BACKGROUND OF THE INVENTION 1. Field of the Invention 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]

[Prior Art and Problems to be Solved by the Invention]
Various structures have been developed and put into practical use for attaching and fixing a bubble tube to the body of a spirit level, but it is possible to attach and fix the bubble tube at a specified angle without the need for screw fixing and bonding work. is not.

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

[0004]

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 both ends of the bubble tube 2 are fitted and fitted to the opening edges of the mounting opening 3 and installed in the mounting opening 3. Mating edge 4
Are formed so as to face each other, and the fitting edge 4 is formed so as to face the opening edges of several sets of the mounting opening portions 3 and a pair of fitting edges 4 are selected, so that the lengthwise direction of the body 1 is selected. A pair of sandwiching members 5 configured so that the bubble tube 2 can be installed over the mounting opening 3 so as to form a predetermined angle, and the fitting opening 5 is fitted and locked together from both the front and back of the mounting opening 3.・ 5 to bubble tube 2
A peep window 6 is formed to expose the opening, and a holding edge portion 7 for holding the bubble tube 2 is formed inside the holding members 5 to hold the bubble tube 2 in the erected state on the fitting edge 4. Are fitted and fitted, and the pair of holding members 5, 5 are fitted and locked to each other from both the front and back sides of the fitting opening 3 with the body 1 interposed therebetween, and the bubble tube 2 is held by the holding edge. The present invention relates to a bubble tube mounting structure of a bubble tube type level, which is configured to be held by a portion 7 and to be able to hold and fix the bubble tube 2.

[0006]

[Function] The bubble tube 2 is erected on the selected pair of mating edges 4.
Is attached and fitted, 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 at the holding edge portion 7.
Hold it in place.

The bubble tube 2 is positioned by the fitting edge 4 at an appropriate angle, and is fixed by the holding edge portion 7 and the fitting edge 4 without displacement.

[0008]

EXAMPLE This example is an example relating 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. A joint edge 4 is formed.

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 fitting edge 4 is parallel to the longitudinal direction of the body 1. State and 45
It can be set in 90 ° and 90 ° positions.

On the other hand, a pair of clasp members 5 and 5 made of resin, respectively.
Respectively, a locking claw 8 and a locking hole 9 are formed, one locking claw 8 locks the other locking hole 9 and the other locking 8 locks one locking hole 9 The sandwiching members 5, 5, sandwiching the body 1 (mounting opening 3), can be detachably slidably engaged with one touch.

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

According to the present invention, by appropriately designing the fitting degree of the fitting edge 4, the fitting degree of the holding members 5 and 5, and the holding support of the holding edge portion 7, it is possible to fix screws completely. It is possible to attach and fix the bubble tube 2 at a predetermined angle position by making the adhesion process etc. defective.
Depending on the case, it is possible to reinforce the fixing strength by attaching a screw or an adhesive process.

In the figure, reference numeral 10 is a curved measurement reference surface portion formed on a curved surface so as to be compatible with a curved measurement object 11 such as a pipe or an erected pipe, 12 is a peep window for measurement formed on the curved measurement reference surface portion 10, 13 is a luminous sheet.

[0015]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the bubble tube is simply fitted to the fitting edge selected so as to have the desired orientation without screw fixing and bonding work. The bubble tube can be attached and fixed at a predetermined angle simply by pressing and holding the holding members from both the front and back sides, which greatly improves the manufacturing work of the level and provides a low-priced bubble level. It has a bubble tube mounting structure.
