Abstract

The utility model relates to a push rod type module locking mechanism used for locking modules. A bracket of a clamping hook is arranged in a bottom board of a bracket of an inserting box. The bracket of the clamping hook is connected with a right angle clamping hook by a shaft of the clamping hook. A restoring spring of the clamping hook is installed on the shaft of the clamping hook. The right side of the clamping hook is provided with a push rod in a transverse direction. The right end of the push rod is arranged in a framework. The push rod in the framework is penetrated with a pressure spring. A small door is installed on the right end of the push rod. Chutes of the small door are arranged on two inner side walls of the small door. The utility model has the advantages of simple structure, convenient use, high work efficiency of production and maintenance, etc.

Description

Post rod type module latch mechanism

The utility model relates to a kind of post rod 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 post rod type module latch mechanism of production, maintenance work efficient.

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

A kind of post rod type module latch mechanism that is used for locking module, it is characterized in that: in subrack support base plate, be provided with a grab support, on the grab support, be connected with a right angle grab with the grab axle, the grab reduction torsion spring is installed on the grab axle, be horizontally arranged with a push rod on the right side of grab, the right-hand member of this push rod is arranged in the framework, has placed stage clip on the push rod in framework, at push rod right-hand member head wicket is installed.

For level promotes wicket, the two side is provided with the wicket chute in the wicket.

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

Fig. 1 is the module diagram that has post rod type module latch mechanism

Fig. 2 looks schematic diagram for Fig. 1 right side

Fig. 3 is the enlarged diagram of Fig. 2 post rod type module latch mechanism

Fig. 4 is for using finger push wicket schematic diagram

Fig. 5 looks right angle grab schematic diagram for Fig. 3 left side

Fig. 6 is for there being the schematic diagram of wicket chute on the two side in the wicket

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6: a kind of post rod type module latch mechanism that is used for locking module, it is provided with a grab support 3 in subrack support base plate 2, on grab support 3, be connected with a right angle grab 4 with grab axle 8, grab reduction torsion spring 7 is installed on grab axle 8, be horizontally arranged with a push rod 5 on the right side of grab 4, the right-hand member of this push rod 5 is arranged in the framework 6, has placed stage clip 9 on the push rod in framework 6, at push rod 5 right-hand member heads wicket 10 is installed.

For level promotes wicket 10, the two side is provided with wicket chute 11 (see figure 6)s in the wicket 10.

When the slide rail of module 1 on subrack inserts, grab 4 pressurizeds, grab 4 is around 8 rotations of grab axle, when grab 4 front portions flushed with the module base plate, module continued to move ahead, when module arrives the precalculated position, because the effect of torsion spring 7 torsion, grab 4 is around 8 revolutions of grab axle, and module 1 is locked (see figure 1).

When module 1 when slide rail is extracted on subrack, with anterior wicket 10 (see figure 4)s of finger push module faceplate, wicket 10 stretches into along wicket chute 11 with finger and slides inwards, push rod 5 is pushed down grab 4, and grab is around 8 rotations of grab axle, when grab 4 front portions are concordant with the module base plate, grab 4 breaks away from subrack bottom oblong aperture, the module release holds module 1 and outwards moves, and module skids off 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.
