CN209725048U - A kind of limiting buffer device - Google Patents

Abstract

The utility model relates to a kind of limiting buffer devices, including limit pedestal, limited block, rubber pad and pin.The rubber pad is mounted in limited block, and it is rubber pad between limited block and pedestal that limited block, which is mounted on the sliding slot of limit pedestal, play buffer function, directly contacting between limited block and limit pedestal is avoided, impact force and noise is reduced, improves limit reliability.The buffer limiter of the utility model can play the role of buffering to external force, make to reduce direct collision between the structural member of contact, reduce noise and destruction, play good position-limiting action.

Description

A kind of limiting buffer device

Technical field

The invention belongs to mechanical design fields, are related to a kind of limiting buffer device, the limit suitable for optoelectronic device work.

Background technique

Caging system is one of the most common design in Machine Design.There are many multiplicity, such as spring for the mode of limit Limit, rubber limit, rigid limit, electromagnetism limit, limiting buffer device provided by the utility model belong to one kind of rubber buffer, With simple with structure, adjustment is simple, convenient disassembly, advantage effective, small in size is buffered.

Summary of the invention

Technical problems to be solved

In order to avoid the shortcomings of the prior art, the present invention proposes a kind of limiting buffer device, by the fixed limit of the limiter In bit architecture, structure limit can be realized.

Technical solution

A kind of limiting buffer device, it is characterised in that including limited block 1, limit pedestal 2, rubber pad 3 and pin 4；Limited block 1 On the slideway in limit pedestal 2, rubber pad 3 is located in 1 groove of limited block, and rubber pad 3 is made to occupy limited block 1 and limit base Between seat 2, pin 4 is fixed on the mounting hole of limit pedestal 2.

The limited block 1 is equipped with a kidney slot, so that limited block 1 moves on the sliding slot of limit pedestal 1, until with Pin 4 contacts.

Rubber pad 3 is located between limited block 1 and limit pedestal 2, plays buffer function, reduces the collision to limit pedestal 2 It destroys.

Kidney slot on limited block 1 is compressed, the design of kidney slot is so that limited block when external force is collided by spring pad 3 1 moves on the sliding slot of limit pedestal 1, until contacting with pin 4, elongates stroke-limit；After external force is eliminated, pass through rubber pad 3 itself retractilities push limit block reset.

Beneficial effect

A kind of limiting buffer device proposed by the present invention, including limit pedestal, limited block, rubber pad and pin.The rubber Pad is mounted in limited block, and limited block is mounted on the sliding slot of limit pedestal, is rubber pad between limited block and pedestal, is played slow Punching effect avoids directly contacting between limited block and limit pedestal, reduces impact force and noise, it is reliable to improve limit Property.Buffer limiter of the invention can play the role of buffering to external force, make to reduce between the structural member of contact and directly touch It hits, reduces noise and destruction, play good position-limiting action.

1- limited block, 2- limit pedestal, 3- rubber pad, 4- pin.

Specific embodiment

Now in conjunction with embodiment, attached drawing, the invention will be further described:

Refering to fig. 1, Fig. 2 and Fig. 3.

Buffer limiter, including limited block 1, limit pedestal 2, rubber pad 3, pin 4.

Wherein rubber pad 3 is fixed in 1 groove of limited block, is then mounted on limited block 1 on the slideway of limit pedestal 2, Then pin 4 is fixed on the mounting hole of limit pedestal 2.

When external force is on limited block 1, by kidney slot, limited block 1 moves ahead compressing rubber pad 2, avoids limited block 1 With directly contacting for limit pedestal 2, impact force and noise, extending structure service life are reduced, good limit performance, Jin Erti are played High overall structure performance.After external force is eliminated, by the retractility of rubber pad 3 itself, limited block 1 is pushed to reset.
