Summary of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned background technology, and propose mechanical anti-shutdown gear
Pin.
The purpose of this utility model is implemented by following technical solution: mechanical anti-shutdown backing pin, it includes door
Pin and badge two parts composition, the door bolt are stretched in the groove of badge and are mutually clamped, and the door bolt is mounted on wall
On face, the badge is mounted on a door；
The door bolt includes guide, mounting plate, pin, spring, washer and adjusting nut composition；
The guide is integrally cylindrical and is mounted on the mounting plate, be equipped in the guide pin,
Spring, washer and adjusting nut, the head of the pin are in the outer edge of the upper end of guide described in arc-shaped and stretching, institute
Spring, washer and adjusting nut are from top to bottom sequentially installed in the guide stated；
The badge includes clamp and mounting hole two parts composition, and the clamp is made of three sections of circular arcs, described
The radius of the Inner arc of clamp and the head arc-shaped of pin are mutually clamped.
In the above-mentioned technical solutions: the top of the minimum point of circular arc and the guide is located at together in the clamp
On one horizontal plane.
The utility model has the advantages that 1, the utility model structure is simple, and working service is convenient and strength-saving, and safety can
It leans on, while proportionally zooming in and out not and influence it using function, adapt to various occasion demands, 2, the utility model producing
The narrow place of site space, had not only been able to satisfy the requirement of anti-shutdown, but also was not take up channel space.

Specific embodiment
The performance that according to the present invention will be described in detail below with reference to the accompanying drawings, but they are not constituted to the utility model
It limits, it is only for example, while by illustrating the utility model the advantages of will become clearer and be readily appreciated that.
Referring to Fig.1 shown in -4: mechanical anti-shutdown backing pin, it includes door bolt 9 and 10 two parts of badge composition, the door
Pin 9 is stretched in the groove of badge 10 and is mutually clamped, and the door bolt 9 is mounted on the wall, and the badge 10 is mounted on
Men Shang；
The door bolt 9 includes that guide 1, mounting plate 2, pin 3, spring 4, washer 5 and adjusting nut 6 form；
The guide 1 is whole cylindrical and is mounted on the mounting plate 2, is equipped with pin in the guide 1
Nail 3, spring 4, washer 5 and adjusting nut 6, the head of the pin 3 are in arc-shaped and the upper end for stretching out the guide 1
Outer edge is from top to bottom sequentially installed with spring 4, washer 5 and adjusting nut 6 in the guide 1；
The badge 10 includes that clamp 7 and 8 two parts of mounting hole form, and the clamp 7 is made of three sections of circular arcs, institute
The radius of the Inner arc for the clamp 7 stated and the head arc-shaped of pin 3 are mutually clamped.
The top of the minimum point of circular arc and the guide 1 is located on the same horizontal plane in the clamp 7.
As shown in Figure 1, Figure 2, Figure 3 shows: wherein Fig. 1 and Fig. 2 forms door bolt 9, and Fig. 2 is the detailed cloth of the internal part of door bolt 9
It sets, is successively assembled from the lower part of guide 1, wherein the 3 hemispherical contact of pin just all stretches out guide 1, from top to bottom
It is sequentially loaded into spring 4 and washer 5, finally screws in adjusting nut 6, door bolt 9 is completed and assembles.
Door bolt 9 is fixed on wall behind the door by mounting plate 2.Fig. 3 is that the structure of the badge 10 in the utility model is shown
It is intended to, left side working portion is made of (i.e. three sections of circular arcs of clamp 7) three sections of circular arcs, wherein the inner arc radius ratio of clamp 7
3 radius of pin is slightly larger so that it is convenient to engage；
Badge 7 is fixed on the door leaf back side by mounting hole 8.7 circular arc lowest part of badge should be with the guide in door bolt 9 when installation
1 the top is located on the same horizontal plane.Door bolt 9 after the installation is completed, can be changed by the screw-in depth of adjusting adjusting nut 6
Spring clamp force makes badge 7 that can easily slip over door bolt 9 back and forth and door bolt 9 is made to block badge 7.
Above-mentioned unspecified part is the prior art.
