JPH02211698A - Positioning device for three member - Google Patents

Abstract

PURPOSE:To obtain positioning structure having high accuracy in a small space by arranging a first member having a hole for positioning and second and third members having protruding sections fitted into said hole on both sides of the first member. CONSTITUTION:The protruding sections 2, 6 of second and third cabinets 1, 5 are fitted into the hole 4 of a first cabinet 3 so as to hold the first cabinet 3 by the second and third cabinets 1, 5. The three cabinets are clamped and unified by a machine screw. Accordingly, the positioning of the three cabinets can be determined by one hole, thus improving dimensional accuracy, then positioning the three cabinets in a small space.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a three-member positioning device used in video equipment and the like.

BACKGROUND OF THE INVENTION In recent years, cabinets and frames for video equipment and the like are required to have high positional accuracy, and since space is scarce, it is required to position them in as small a space as possible.

An example of a conventional cavity installation device will be described below with reference to the drawings.

Figure 3 shows a conventional cabinet positioning device 21\-
FIG. In FIG. 3, the cabinet 7 is provided with a first hole 8 for positioning. There are no restrictions. Furthermore, the cabinet 12 has a second protrusion 1 that fits into the second hole 11.
3 is provided.

A method for assembling the cabinet configured as described above will be described below.

First, the cabinet 7 and the cabinet 9 are positioned by fitting the protrusion 10 into the first hole 8 . Next, the cabinet 9 and the cabinet 12 are positioned by fitting the second protrusion 13 into the second hole 11.

Problems to be Solved by the Invention However, in the conventional configuration described above, a dimensional error occurs between the second hole 11 and the first convex portion 100. Moreover, since there are two holes, it takes up space. was.

The present invention solves the above-mentioned problems of the prior art, and aims to provide a three-member positioning device for positioning one/piece in the cavity 3 with improved mounting accuracy and in a smaller space.

Means for Solving the Problem In order to achieve this object, the three-member positioning device of the present invention includes: a first member having a positioning hole; and a first member that is fitted into the hole. The second part has a convex part.
and a third member.

Function: With this configuration, the three members can be positioned with one hole, so highly accurate positioning can be achieved in a small space.

EXAMPLE An example of the present invention will be described below with reference to one screen.

FIG. 1 is an exploded sectional view of three cabinets according to a second embodiment of the present invention, and FIG. 2 is an exploded perspective view of the same embodiment.

In FIGS. 1 and 2, -1 is a second cabinet, and -2 is a convex portion provided on the second cabinet 1. In FIGS.

3 is a first cabinet and -4 is a hole provided in the first cabinet 3, which fits into the screen 2 to determine the positions of the second cabinet 1 and the first cabinet 3. , 6 is the third cabinet, -6 is a convex portion provided on the third cabinet 6, which fits into one hole 4, and connects the first cabinet 3.
The positions of the third cavity and the cutter 6 are determined by the hole 4 and the protrusion 6.

The positioning of the cabinet configured as described above will be explained below.

Second. The third cabinet 1, 6 is inserted into the hole 4 of the first cabinet 3 so as to sandwich the first cabinet 3 therebetween. Convex portion 2.6 of third cavity throat 1.6
mate. Then, the three cabinets are fastened together using screws (not shown) to form a body.

As described above, according to this embodiment, the first cabinet has one positioning hole, and the second cabinet has a convex portion that fits into the hole. The third cab is equipped with a t-no) and 6 heno, and the second. The first cabinet is inserted into the hole of the first cabinet by the third cavity.
By fitting the convex part of the third cabinet, the positioning of the first three cabinets can be determined with one hole, which improves dimensional accuracy - and allows the positioning of the three cabinets to be done in a small space. can do.

Effects of the Invention As described above, the present invention provides a first member (first cabinet in the embodiment) having a positioning hole, and a second member having a convex portion that fits into the hole. The third member (in the example, the second member.
a third cabinet); The first member is sandwiched between the third member and the second member is inserted into the hole of the first member. Since the convex portion of the third member is fitted, the positioning accuracy of the three members is improved, and an excellent three-member positioning device that can perform positioning in a small space can be realized. .
