Description

[Detailed description of the invention] Industrial application field This invention is connected to a rotating brush and washing machine for high-pressure spray cleaning used for cleaning automobile bodies, food manufacturing machines and food processing plants, buildings and equipment, etc. This invention relates to a coupling joint for a rotating brush that can be easily separated and detached from a cleaning gun.

Conventional technology When using a conventional high-pressure spray cleaning rotating brush, it is desirable to separate and remove the rotating brush and the cleaning gun pipe, and use a commercially available coupler joint to facilitate this process, but it is difficult to clean multi-angle surfaces. When doing this, the spinning motion of the male and female sides of commercially available or conventional cupradio joints is a soft rotation, so when the brush comes into contact with the surface of the object to be cleaned when the rotating brush body is in operation, it does not touch the surface of the object to be cleaned. However, when cleaning deformed surfaces of the object to be cleaned and multi-angle surfaces other than flat surfaces, when this brush itself rotates with jetted cleaning water, the point of force is applied in the direction of rotation, physically impacting the cleaning surface. Not only does it not match the focus, but the brush surface ends up being swung in the opposite direction. Therefore, the application of cupradio joints to rotating brushes is of no value.

Problems that the invention aims to solve Spray cleaning machines have different cleaning pressures due to the jet water pressure depending on the mechanical performance, and the cleaning pressure can also be adjusted by changing settings. Even when connected to the cleaning gun pipe, the shaft that can be spun is too loose, so when the desired rotating brush is attached, it spins easily and is not suitable for the object to be cleaned.Furthermore, if it is a fixed connection type, it can be used for cleaning polygonal surfaces. There are problems such as difficulty in doing so.

Therefore, the present invention provides a capillary joint that can be easily separated and removed, and can also adjust the spin softness of the capillary joint according to the pressure of the washing machine, thereby making it possible to clean multi-angle surfaces of the object to be washed.

Means for Solving the Problems The structure of the present invention for achieving the above object will be explained with reference to FIG. An insertion tube 4 provided on one side of the male coupler 1 and an insertion port 9 provided on one side of the tubular female coupler 8 screwed onto the cleaning gun pipe 20 are connected to the insertion tube 4 provided around the insertion tube 4. In a device in which the coupling groove 3 is removably connected by engaging and disengaging the spin ball 11 provided in the peripheral wall of the insertion port, a flange 2 is provided on the outer periphery of the middle part of the male coupler 1, and a flange 2 is provided on the outer periphery of the middle part of the male coupler 1. A slide ring 12 is slidably attached to the outer periphery of the side via a spring 14 for engaging and disengaging the spin ball 11 from the engagement groove 3 and abutting against the flange side surface 2a. Spin softness adjustment ring 1 that can be screwed onto the threaded part 18 provided in
This is a coupling joint for a rotating brush of a high-pressure spray cleaning machine, in which the contact friction force between the slide ring side end surface 12b and the flange side surface 2a is increased or decreased by the movement of the slide ring 7 back and forth through a spring 19.

Function The male coupler 1 is installed by screwing one end of the side opposite to the insertion pipe 4 into the liquid receiving pipe 7 on the rotating brush body 6 side, and the female coupler 8 is attached to the end of the cleaning gun pipe 20. Attached by screw fit,
When inserting the insertion tube 4 of the male coupler 1 into the insertion port 9 of the female coupler 8, by sliding the slide ring 12 against the spring 14, the spin ball 11 is temporarily moved to the outside. After insertion, the male coupler 1 and the female coupler 8 are connected in a spin-able manner by engaging across the engagement groove 3 of the insertion tube 4. Then, attach the spin soft hardness adjustment ring 17 to the threaded part 18.
When the slide ring 12 is slid in the tightening direction, the pressure of the spring 19 causes the side end surface 12 of the slide ring 12 to tighten.
b strongly presses against the flange side surface 2a, increasing mutual frictional force, and when the spin softness adjustment ring 17 is slid in the loosening direction, the slide ring 1
2 and the flange side surface 2a is weakened, and therefore the cleaning gun pipe 20 and the liquid receiving pipe 7 are
The rotating brush main body 6 side rotated by the washing water passing through the flange side 2a of the coupling joint
Since the rotating brush can be rotated with appropriate hardness by the and slide ring 12, even when the cleaning water pressure is low, the rotating brush does not rotate around at the coupling joint, and it can be used on any surface of the object to be cleaned. The rotating brush can be pressed against the surface to be cleaned with an appropriate force for rotational cleaning. Also, the slide ring 12 is connected to the spring 14.
When sliding the spin soft hardness adjusting ring 17 in the direction of loosening it by the screw part 18, the sliding range of the slide ring 12 is expanded, and the coupling between the female coupler 8 and the male coupler 1 is Easy to remove (separate).

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In Figs. 1 and 2, 1 has a flange 2 on the outer circumferential side of the middle part, an insertion tube 4 having an engagement groove 3 locally circumferentially provided on one side, and a water liquid receiving part of the rotating brush body 6 on the other side. This is a male coupler in the form of a tube with a screw hole 5 for screwing into the tube 7.

Reference numeral 8 denotes a female coupler having an insertion port 9 of the insertion pipe 4 on one side and a screw hole 10 on the other side for screwing into the cleaning gun pipe 20 of a cleaning machine. Several spin balls 11 are provided on the peripheral wall of 9, which can engage and detach from the engagement groove 3 when the insertion tube 4 is attached or detached.
A slide ring 12 is fitted on the outside of the circumferential wall to face and contact the side surface 2a of the flange 2 with a spring 14 interposed between it and the circumferential wall step 13, and the slide ring is attached to the outer periphery of the end of the circumferential wall. The retaining ring 15 allows the slide ring 12 to slide in only one direction. Further, the spin ball 11 is provided on the inner periphery of the side end of the slide ring 12.
The slide ring 12 is provided with a tapered notch 12a for engaging or disengaging with the engagement groove 3 of the insertion tube 4, and the slide ring 12 is moved against the spring 14 when the insertion tube 4 is inserted into or removed from the insertion port 9. By sliding, each spin ball 11 falls into the tapered notch 12a, making it easy to install and remove the insertion tube 4, and when you release your hand from the slide ring 12, the force of the spring 14 returns the slide ring 12 to its original position. Returning, the spin ball 11 protrudes inward and engages with the engagement groove 3 when the insertion tube 4 is installed. In addition, in order to ensure watertightness when connecting the insertion port 9 and the insertion pipe 4, an O
Attach ring 16 and backup spring 16',
It is arranged to come into close contact with the outer peripheral portion 4a of the tip of the insertion tube 4, which has a slightly smaller diameter.

Reference numeral 17 denotes a spin soft/hardness adjustment ring screwed onto a threaded part 18 provided on the outer periphery of the other side of the female coupler mold 8. A spring 19 is interposed between the ring 17 and the slide ring 12. By moving the degree adjustment ring 17 in the pipe axis direction, the strength of the pressure contact between the side end surface 12b of the slide ring 12 and the flange side surface 2a is adjusted, and the cleaning gun pipe 20 on the cleaning machine side and the rotating brush main body 6 are connected. The spin of the coupling joint can be adjusted to a hardness suitable for cleaning with a rotating brush and for changing the direction of the cleaning surface of the cleaning object.

Effects of the Invention Spray jet cleaning machines have different cleaning pressure ranges from the lower limit to the upper limit and their maximum and minimum pressures depending on the machine performance. With spin-capable coupler joints, the shaft may become too loose and the attached rotating brush surface may not be able to bounce back from the cleaning surface, and if used for a long time, the shaft of the coupler may wear out, causing even more spin. However, since the cupradio joint of the present invention has the above-mentioned structure, it not only allows easy attachment and detachment of the cleaning pipe on the cleaning machine side and the rotating brush body with one touch, but also By turning the spin soft hardness adjustment ring, you can freely adjust the strength of the contact friction force between the flange of the male coupler and the slide ring of the female coupler. However, the rotating brush does not wander around the shaft of the coupling joint, and the rotating brush surface can always be kept in stable contact with the surface of the object to be cleaned.
Even when cleaning multi-angle surfaces of the object to be cleaned, there is no need to change the direction of the brush surface each time the cleaning gun pipe rotates.By rotating the adjustment ring, the brush surface can freely change direction and conform to the cleaning surface, thereby cleaning the object from multiple angles. Surface cleaning can be carried out effectively, and this cupradio joint has the advantage of being able to be used without any problems in various types of cleaning machines with different cleaning pressures.
