Description

[Detailed Description of the Invention] The present invention relates to a device for temporarily fixing a temporary fixing plate by hooking it onto an object to be attached, and aims to provide a device that can facilitate the installation and removal of the temporary fixing plate. be.

In a television receiver, a mounting plate for a variable resistor is temporarily attached to a tuner case, and after wiring and the like are completed, the plate is permanently attached using screws or the like.

When performing such temporary fixing, it is essential that the temporarily attached mounting plate can be attached and detached at will.

For this purpose, an L-shaped locking piece is cut out from the tuner case, and a through hole provided in the mounting plate is fitted to this piece.
A sliding type is used for temporary fixing.

First, conventional examples of such temporary fixing devices will be explained with reference to FIGS. 1 to 3.

Here, 1 is an attached object such as a tuner case, 2
is a temporary fixing plate such as a variable resistor mounting plate to be temporarily fixed to this, and locking pieces 37 and 4 are cut and raised from the mounting plate 1, and locking pieces 37 and 41 are cut and raised from the mounting plate. The through holes 5 and 6 formed in 1 are through holes provided in the temporary fixing plate 2 so as to fit into the locking pieces 3 and 4 thereof.

Note that the locking piece 4 and the through hole 6 are provided auxiliary, and the temporary locking part 4 is not designed to press and hold the temporary locking plate 2, and is not intended for maintenance. Since there is a considerable margin in the dimensional relationship in the matched state, this is not a problem here.

The problematic part is the temporary fixing part between the locking piece 3 and the through hole 5.The locking piece 3 as a whole is inclined in the direction of the mounting plate 1, and only its free end portion 7 is attached to the mounting plate. It is slightly bent in the opposite direction to 1.

For temporary fixing, the through holes 5 and 6 of the temporary fixing plate 2 are fitted into the locking pieces 3 and 4, and in this state, the temporary fixing plate 2 is slid downward in the direction of arrow A. 1,
As shown in FIG. 2, the temporary fixing plate 2 engages with the periphery of the through holes 5 and 6, whereby temporary fixing is achieved.

At this time, since the locking piece 3 is slightly inclined in the direction of the mounting plate 1, the area around the through hole 5 is covered by the locking piece 3 as shown by arrow B. It is pressed in the direction of the mounting plate 1 and is clamped to prevent rattling.

However, in such conventional devices, when the locking piece 3 is cut and raised from the object 1 to be attached, the distance between the object 1 and the free end portion 7 of the locking piece 3 may be shortened due to machining errors. is often smaller than the standard size,
In such a case, when the temporary fixing plate 2 is attached to or removed from the mounting plate 1 as shown in Fig. 1-2, the temporary fixing plate 3 is pressed more forcefully than necessary by the locking piece 3. This has resulted in a drawback that a large amount of force is required for attachment and removal, resulting in poor workability.

Therefore, the present invention solves such conventional drawbacks and provides a device that can easily attach or detach a temporary fixing plate with good workability even when there is an error in the machining dimensions of the fixing piece of the object to be attached. The purpose is to

An embodiment of the present invention will be described below with reference to FIGS. 4 to 6.

It should be noted that the same parts as in the prior art are denoted by the same reference numerals as in FIGS. 1 to 3, and the explanation thereof will be omitted.

In this device, as shown in FIGS. 5 and 6, there are holes connected to the through hole 5 on both sides of the peripheral portion 8 of the through hole 5 that is pressed by the locking piece 3 when temporarily secured by the slide. It is distinctive in that notches 9 are formed.

If the cut 9 is formed in this way, the pressed peripheral portion 8 will be formed into a tongue shape as shown in FIG. Arrow A
Even if the locking piece 3 is processed to be inclined slightly in the direction of the attached plate 1 when it is slid in the direction indicated by the arrow B, the pressing force in the direction of the arrow B is large. The tongue-like peripheral portion 8 can be elastically bent slightly in the direction of arrow C, and the locking plate 2 can be slid with an appropriate force that is not too large.

Therefore, even if there is a machining error in the locking piece 3, an appropriate force is required when the locking plate 2 is attached or removed, and the workability can be significantly improved. be.

As described above, according to the present invention, it has been possible to realize a practical temporary fixing device that allows a temporary fixing plate to be easily attached to or removed from an object to be attached with good workability.

Claims (1)

[Scope of utility model registration request] An L-shaped locking piece is cut and raised from the mounting plate, and the free end of this locking piece is formed so as to be slightly curved in the opposite direction to the mounting plate, and is temporarily fixed. The temporary fixing plate is provided with a through hole that fits into the locking piece, and when the locking piece and the through hole are fitted into each other and are slid together, the locking piece is attached to the peripheral area of the through hole. What is claimed is: 1. A temporary fixing device configured to press and hold the locking plate, and having notches connected to the through holes formed on both sides of a portion of the locking plate pressed by the locking pieces.
