Abstract

The utility model relates to a clasp type module locking mechanism which is used for locking modules. A bottom board of a module is fixedly connected with a supporting seat which is provided with a clasp. The front surface of the clasp is provided with a downward barb and the back surface of the clasp is provided with an upward spanner board. The lower part of the spanner board is connected with a support board. The support board and the supporting seat are transversely inserted with shafts of the clasp. Torsional springs are penetrated on the shafts of the clasp. The lower part of a panel of the is provided with a movable door which corresponds to the spanner board of the clasp. The back surface of the movable door is provided with a restoring spring. The utility model has the advantages of simple structure, convenient use, etc., and can enhance the work efficiency of production and maintenance.

Description

Clasp type module latch mechanism

The utility model relates to a kind of clasp type module latch mechanism, and it is applicable to electronic module is installed on the subrack support base plate easily.

At present, the electronic module that uses at aspects such as electronic instrument, equipment, generally be with its by screw on subrack support base plate, when needs dismounting, maintenance, then need with screwdriver dismounting screw one by one, give like this produce, maintenance, use brought many constant.

The purpose of this utility model provides a kind of simple in structure, easy to use, can improve the clasp type module latch mechanism of production, maintenance work efficient.

For achieving the above object, the utility model is taked following design:

A kind of clasp type module latch mechanism that is used for locking module, module base plate, module faceplate are arranged, it is characterized in that: on the module base plate, be connected with a supporting seat, one grab is set on this supporting seat, there is downward barb the front of this grab, and there is spanner plate upwards the back of this grab, is connected with supporting bracket in the bottom of spanner plate, transverse splicing has a grab axle on supporting bracket and supporting seat, and cross-under has torsion spring on the grab axle.

In order to pull spanner plate with finger, be provided with a dodge gate in the bottom of module faceplate, corresponding the spanner plate of grab is connected with back-moving spring in the dodge gate back in this dodge gate.

The utility model is described in further detail below in conjunction with accompanying drawing.

Figure 12 is Figure 11 schematic top plan view

Referring to Fig. 1～shown in Figure 12: a kind of clasp type module latch mechanism that is used for locking module, it is arranged on the module base plate 14 of module 1, on module base plate 14, be connected with a supporting seat 9, one grab 3 is set on this supporting seat 9, there is downward barb 8 front of this grab 3, and there is spanner plate 10 upwards the back of this grab 3, is connected with supporting bracket 13 in the bottom of spanner plate 10, transverse splicing has a grab axle 12 on supporting bracket 13 and supporting seat 9, and cross-under has torsion spring 11 on grab axle 12.

Supporting seat 9 is to be welded on the module base plate 14.

In order to pull spanner plate with finger, be provided with a dodge gate 6 in the bottom of module faceplate 4, corresponding the spanner plate 10 of grab is connected with back-moving spring 7 in dodge gate 6 back in this dodge gate 6.

When the slide rail 2 of module 1 on subrack inserts, the barb of grab 3 front portions and subrack bump against (see figure 1), grab 3 is around 12 rotations of grab axle, when the barb of grab 3 front portions flushes with the module base plate, module continues the (see figure 2) that moves ahead, when module arrives the precalculated position, because the effect of torsion spring 11 torsion, grab 3 is around 12 revolutions of grab axle, and module 1 is locked (see figure 3).

When module 1 when slide rail is extracted on subrack, hand stretches into (see figure 4) from module faceplate 4 anterior dodge gates 6, dodge gate 6 stretches into around door-hinge with finger and rotates inwards, finger is pushed down the spanner plate 10 of grab, and grab 3 is around 12 rotations of grab axle, when the anterior overhead kick 8 of grab is concordant with module 1 base plate, the anterior overhead kick 8 of grab breaks away from subrack bottom oblong aperture, module release (see figure 6) holds module faceplate and outwards moves, and module 1 skids off (see figure 7) along slide rail on the subrack.

The utility model has the advantages that: simple in structure, easy to use, can improve production, maintenance work efficient.
