Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a level that enables mass production of high-precision levels.

[Conventional technology]

In manufacturing levels, it is important to mass-produce high-precision levels.

Conventionally, for example, the vertical vial of a level shown in Publication of Utility Model Publication No. 59-35766 has been fitted into a mounting hole drilled in the body with an adhesive, but while it is simple, it is difficult to Once installed, there are drawbacks that cannot be corrected, and installation requires skill.

[Problem that the invention attempts to solve]

The present invention solves these drawbacks, and the technical problem is to simplify the mounting structure of the vial and mass-produce highly accurate levels.

[Means for solving problems]

In a level device in which a vial 2 is horizontally buried in the upper center of a long and narrow container 1 and a vertical vial 3 is buried in one end, the hollow square container 1 is formed of aluminum molding material. A circular mounting hole 4 is bored in the front and rear walls 1a at one end of the body 1, and a locking rib 5 is integrally formed on the inner surface of the front and rear walls 1a of the body 1 around the mounting hole 4. The bubble tube 3 is held in a C-shaped plastic holder 6 whose diameter can be reduced, and a locking groove 7 that engages with the locking rib 5 is formed on the front and back of the circumferential surface of the holder 6. A locking step 8 is formed on the front and rear peripheral edges of this holder 6 to lock onto the peripheral edge of the mounting window hole 4, and this holder 6 with a bubble tube 3
Fits into the mounting window hole 4 with the diameter reduced,
The locking groove 7 is locked to the locking rib 5, the locking step part 8 is locked to the inner peripheral edge of the mounting window hole 4 of the front and rear walls 1a, and the holder 6 with the vertical vial 3 is installed in the mounting window hole 4. Bury and fix.

〔Example〕

The vertical bubble tube 3 has a circular frame 9 made of plastic.
It is integrally formed within.

The horizontal bubble tube 2 is fitted into a plastic holder 10 via adhesive.

Although the locking ribs 5 are formed over the entire front and rear walls 1a of the container body 1, they may be formed only on the left and right sides of the mounting window hole 4.

In the figure, reference numeral 11 indicates a plastic cap fitted into the openings at both ends of the vessel body 1, 12 indicates a plastic C-shaped ring forming a hanging hole, and 13 indicates a reinforcing rib forming the locking step 8.

[Effect of idea]

As mentioned above, the present invention uses a highly precise aluminum molding material for the vessel body 1, holds the vertical vial 3 in a C-shaped holder 6 with a partially open opening, and attaches the vertical vial 3 to the C-shaped holder 6. When the holder 6 is compressed and fitted into the mounting window hole 4, the holder 6 opens by its own elastic force and the locking grooves 7 on the left and right sides of the holder 6 are connected to the locking ribs 5 on the inner surface of the front and rear walls 1a of the container body 1. Lock the holder 6
Since the locking steps 8 on the front and rear edges are locked on the inner surface of the periphery of the mounting window hole 4 in the front and rear walls 1a of the vessel body 1, the vertical vial 3 can be quickly and accurately installed at the desired position, making it easy to install. We can provide highly accurate levels.

Once installed in the mounting window hole 4, the holder 6 with the vertical vial 3
When the holder 6 is fixed, the locking groove 7 is locked to the locking rib 5, and the front and rear locking steps 8 are locked to the inner surface of the periphery of the mounting hole 4 in the front and rear walls 1a of the container body 1, so an external force is applied to the holder 6. It will not come off unless you shrink it.

In this way, the present invention makes it possible to easily embed and fix the mounting hole 4 by using the elasticity of the holder 6 with the vertical vial 3, and also to improve the work efficiency because the mounting accuracy of the vertical vial 3 can be quickly achieved. Furthermore, since the container body 1 itself is made of aluminum molding material, it is lightweight and has excellent practical effects such as providing a level that is easy to use.
