Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a pipe joint and a pipe connection device using the same.
By making both end surfaces of the two joint members sloped in the same direction and providing latches that can be latched to each other along the slope, connection and removal of the pipe bodies is facilitated by the simple operation of sliding the joint members. It was designed so that it could be carried out.

<Prior Art> When connecting pipe bodies, conventionally, as shown in FIG. It was common to have a structure in which the two ends were inserted. The tube body 1.2 may be a straight tube, as shown in FIG. 6, or may include a so-called elbow tube 2, as shown in FIG. The piping connections in Figure 6 are, for example,
It is used when connecting piping between the inlet side cell 3 and the outlet side cell 4. FIG. 7 shows, for example, a drainage basin 5 and an elbow pipe 2.
It is used when receiving wastewater from etc. The drainage basin 5 includes a basin body 52 provided with an invert 51 and a water sealing device 53 provided inside the basin body 52. The water sealing device 53 is provided to prevent foul odors from rising from the drainage basin 5 through the elbow pipe 1.2.

<Problems to be Solved by the Invention> However, the above-described conventional piping connections have the following problems.

(a) When making a piping connection as shown in FIG. 6, the distance between the inflow side cell 3 and the outlet side cell 4 is generally fixed. Within this fixed distance, it becomes difficult to insert the end portion 21 of the other tube 2 into the receiving portion 11 of one tube 1 in the final piping connection. It is difficult to connect the pipes unless the entire pipe is moved toward either the inlet pipe 3 or the outlet pipe 4.

(b) In the drainage basin structure shown in FIG. 7, if the pipe 1 or 2 is clogged with foreign matter, it is necessary to remove the elbow pipe 2 in order to remove the foreign matter.

To remove the elbow tube 2, it is necessary to pull out the elbow tube 2 in the direction of arrow a. However, in addition to the drainage basin 5 being narrow, the end of the elbow pipe 2 is located within the water sealing device 53 which is even narrower than the drainage basin, making it difficult to remove and install the elbow pipe 2. Become.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pipe joint that solves the above-mentioned problems and allows pipe bodies to be easily connected and removed.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the pipe joint j according to the present invention, 1
A pipe joint including two joint members that are combined to form one pipe, each of the two joint members having end faces that overlap each other on both sides in the radial direction when the pipe is configured. and both end surfaces are slopes that are inclined in the same direction along the axial direction when the tube is configured, and latching portions that are latched to each other are provided on the sides, and 2. Each of the two joint members is removably latched to each other so that the inclination directions of the end faces are opposite to each other, and the latching portion allows sliding in the axial direction. do.

Next, a pipe connection device according to the present invention is a pipe connection device including a pipe having a butt portion, and a pipe joint that covers and connects the butt portion of the pipe, the pipe joint comprising: two joint members that are combined to form one pipe, each of the two joint members having end surfaces that overlap with each other on both sides in the radial direction of the pipe, The both end surfaces are slopes that are inclined in the same direction along the axial direction when the pipe is configured, and latching portions that are latched to each other are provided on the sides, and the two coupling members are latched to each other. are removably latched to each other so that the inclination directions of the end faces are opposite to each other, and the latching portions allow sliding in the axial direction; The piping is connected by tightening along with axial sliding.

Each of the two joint members has end faces that overlap each other on both sides in the radial direction, and both end faces are slopes that are inclined in the same direction along the axial direction, and the two joint members have end faces that overlap each other on both sides in the radial direction. The tubular body is latched to each other so that the latching portions are latched, and the inclination directions of the end faces are opposite to each other, and the latching portions allow sliding in the axial direction. By sliding the two joint members in the axial direction, the tightening force necessary for connecting the tube bodies can be obtained. Therefore, it becomes easy to connect the pipes, and the pipes can be connected reliably.

In addition, each of the two joint members has slopes that slope in the same direction on both end faces along the axial direction, and the sliding in the axial direction is prevented by the latching part so that the inclination directions of the end faces are opposite to each other. Since they are latched to each other so that the pipe diameter corresponds to the sliding position,

<Example> FIG. 1 is a perspective view of a pipe joint according to the present invention, and FIG. 2 is a perspective view of a joint member. 6.7 is a joint member. These coupling members 6.7 are combined to form a tube. The joint member 6.7 may have a well-balanced half-split shape or may be an unbalanced split piece. Preferably, these coupling parts 6.7 are made of plastic. If the material is made of plastic, a pipe fitting having appropriate elasticity and excellent corrosion resistance and chemical resistance can be obtained.

The coupling member 6.7 has end faces (61, 62) overlapping each other on both radial sides when the tube is configured, <71
．． 72). These end surfaces (61, 62),
(71, 72) are slopes that are inclined in the same direction along the axial direction when the tube is constructed, and the end surfaces (61, 72) are inclined in the same direction.
62) and (71, 72), latching portions (63, 64) and (73, 74) are provided on the outer circumferential surfaces of the sides thereof. The latching parts (63, 64) and (73, 74) constitute a kind of hook latching structure. The joint member 6 and the joint member 7 have end faces (61, 62) and (71, 7).
They are latched to each other by latching portions (63, 73), (64, 74) such that the inclination directions of 2) are opposite to each other so as to allow sliding in the axial direction.

3(a>-(c) are diagrams explaining the function of the pipe joint according to the present invention.Both end surfaces (61, 62) of the joint member 6.7
), (71, 72) are axis 0. The slope is inclined at an angle θ with respect to the slope. Since the joint member 6 and the joint member 7 are combined so that the inclination directions of the end faces (61, 62) and (71, 72) are opposite to each other, the joint member 6
When considered based on, as shown in Figure 3 (a),
As the coupling member 7 moves toward the upper side of the slope of the end face (61, 62) of the coupling member 6, the inner diameter formed by the coupling member 6.7 becomes larger.

When the joint member 6 or the joint member 7 is slid in the direction of arrow a, the inner diameter gradually becomes smaller as shown in FIGS. 3(b) and 3(C).

If you slide it in the direction of arrow A, which is opposite to arrow a,
The inner diameter is expanding. Therefore, the relative sliding action of the joint member 6.7 can be used to tighten and connect the pipe bodies that are butted together inside the pipe joint member 6.7. The position of tightening the pipe body is in either direction as shown in Fig. 3(a) or Fig. 3(C), based on the position where the pipe fitting members 6.7 overlap as shown in Fig. 3(b). It can also be set to Therefore, it is possible to follow changes in the pipe diameter.

FIG. 4 shows a specific example of a pipe connecting device using a pipe joint according to the present invention. 8 and 9 are tube bodies that are butt-connected. The tube body 8.9 may be either a straight tube or a curved tube such as an elbow tube. 10 is a spacer made of adhesive, adhesive material, cushion material, or the like.

When attaching the joint member 6.7 to the pipe body 8.9,
The joint members 6.7 separated from each other, for example, the joint member 6, are arranged so as to cover the abutting portion of the tube body 8.9, and the other joint member 7 is fitted from the end side of the joint member 6. . Here, as explained in FIG. 3, when the two joint members 6.7 are slid in the direction of the arrow a, the inner diameter of the joint members 6.7 is reduced, and by tightening the joint members 6.7, the pipe body 8.9 can be connected easily and reliably. Joint member 6
．． When the joint member 6.7 is slid in the direction of the arrow, the inner diameter formed by the joint member 6.7 is enlarged, as explained with reference to FIG. 3, so that the joint member 6.7 can be easily removed. The illustration shows a pipe connecting device that connects two pipe bodies 8.9, so there is only one abutting part, but when three or more pipe bodies are connected, multiple abutting parts occur. . In this case as well, a plurality of abutting portions can be connected with the same pipe joint.

<Effects of the Invention> As described above, according to the present invention, the following effects can be obtained.

(a) Each of the two joint members has end faces that overlap each other on both sides in the radial direction, and both end faces are sloped slopes that are inclined in the same direction along the axial direction. There is a latching part that can be hung,
