Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bubble tube mounting structure of a bubble tube type level for measuring the horizontality, verticality and perpendicularity of a measurement surface or a measurement object.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, various structures have been developed and put into practical use to attach and fix a bubble tube to the body of a level, but the bubble tube is attached at a predetermined angle without the need for screw fixing and bonding work. It cannot be fixed.

According to the present invention, the bubble tube type can be installed and fixed at a predetermined angle without screw fixing and bonding work, and the manufacturing work of the level can be greatly improved and an inexpensive product can be provided. It is a technical problem to provide a bubble tube mounting structure for a container.

[0004]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A mounting opening 3 having a width substantially equal to that of the bubble tube 2 is formed in the body 1, and the bubble tube 2 is mounted and fitted to the opening edge of the mounting opening 3 so as to be installed in the mounting opening 3. Along with the formation of the mating edge 4, a pair of retaining members 5 and 5 engaging and locking are formed with a peep window 6 exposing the bubble tube 2, and the bubble tube 2 is held inside the retaining members 5 and 5. A holding edge portion 7 to be held is formed, the bubble tube 2 is attached and fitted to the fitting edge 4 in a state of being erected, and the pair of holding members 5 and 5 are locked with the body 1 interposed therebetween. A bubble tube mounting structure of a bubble tube type level, characterized in that the bubble tube 2 is fitted and held by the holding edge portion 7 so that the bubble tube 2 can be held and fixed. It is a thing.

[0006]

[Action]

 The bubble tube 2 is attached and fitted to the fitting edge 4 in a erected state, and the pair of holding members 5 and 5 are locked and fitted with the body 1 sandwiched therebetween to hold the bubble tube 2 with the holding edge portion 7. , Hold the bubble tube 2 in place.

The bubble tube 2 is positioned by the fitting edge 4 at a proper angle, and is fixed by the holding edge portion 7 and the fitting edge 4 without being displaced.

[0008]

【Example】

 The present embodiment relates to a bubble tube mounting structure in which the bubble tubes 2 are attached to the aluminum container 1 having an I-shaped cross section at three positions at predetermined angles.

A mounting opening 3 is formed in the bubble tube mounting position of the body 1, and an uneven edge is formed on the opening edge so that the end of the bubble tube 2 is mounted and fitted to the mounting opening 3. It forms a joint edge 4.

In the present embodiment, by connecting and forming several sets of the fitting edges 4 around the entire circumference of the opening edge, the one fitting edge 4 is selected, so that the base 1 is parallel to the longitudinal direction. It can be set to 45 degrees or 90 degrees in the positioning state.

On the other hand, the locking claw 8 and the locking hole 9 are formed in each of the pair of resin-made clamping members 5, 5, and the one locking claw 8 is locked in the other locking hole 9. The other locking member 8 can be locked in one locking hole 9 to sandwich the body 1 (mounting opening 3), and the catching members 5, 5 can be detachably fitted by a single touch. Is configured as follows.

Further, a peep window 6 that exposes the bubble tube 2 is formed on the sandwiching member 5, and the corrugated ridges and ridges are formed so as to correspond to the case where the sandwiching inside is mounted and fitted at various angles as described above. To form a holding edge portion 7 for holding the bubble tube 2.

In addition, according to the present invention, by appropriately designing the fitting degree of the fitting edge 4, the locking fitting degree of the holding members 5, 5, and the holding support degree of the holding edge portion 7, it is possible to completely fix the screws and screws. Although the bubble tube 2 can be mounted and fixed at a predetermined angle position by making the bonding process defective, in some cases, screw fixing or a bonding process can be performed to reinforce the mounting and fixing strength.

In the figure, reference numeral 10 is a curved measurement reference surface portion formed on a curved surface so that it can also be used for a curved measurement object 11 such as a pipe or an erected pipe, and 12 is a peep for measurement formed on the curved measurement reference surface portion 10. The window 13 is a luminous sheet.

[0015]

[Effect of device]

 Since the present invention is configured as described above, the bubble tube can be attached and fixed at a predetermined angle without fixing with screws or adhering work, and the manufacturing work of the spirit level can be remarkably improved and a bubble product which can provide an inexpensive product can be provided. It becomes a bubble tube mounting structure of a tube level.
