CN2093113U - Automatic locking device for damping chair - Google Patents

Abstract

The utility model discloses an automatic locking device for a damping chair, which relates to an automatic locking and stopping mechanism and is suitable for various damping chairs with level, front and back hang. The utility model is mainly composed of a ratchet pawl, ratchet bars, stretching flexible shaft and springs; when the brake pedal is stepped down, the ratchet pawl is meshed with ratchet bars by the stretching flexible shaft which is moveable linked with the brake pedal to make the level backwards displacement of the damping chair relative to the chair frame be locked. The utility model has the advantages of simple structure, easy fabrication and safety.

Description

Automatic locking device for damping chair

A kind of automatic lock locking apparatus of shock absorbing seat relates to the automatic lock locking mechanism, is applicable to various shock absorbing seats with horizontal front and rear suspension, is used for short wheelbase engineering overland vehicle.

Application number is 85204298 patent, a kind of two-way hanging vibration reduction seat is disclosed, though this two-way shock absorbing seat can reduce the pitch vibration of various vehicles to chaufeur effectively, but when vehicle during at emergency braking, under the effect of brake pedal counter-force, make seat displacement backward, cause brake action to lag behind, reduced the safety of braking.

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of when car brakeing, make horizontal front and rear suspension shock absorbing seat backward displacement movement automatically by the automatic lock locking apparatus of a kind of shock absorbing seat of locking.

The utility model is achieved in that

One end of spring (2) catches on brake pedal (1), and the other end catches on an end of stretching flexible axle (3); The other end of stretching flexible axle (3) catches on the tail end of ratchet (7); Ratchet (7) is movably articulated on the vehicle frame (8) with bearing pin (9); One end of torsion spring (6) catches on the front end of ratchet (7), and the other end colludes on vehicle frame (8); Ratchet (5) is fixed on the seat transition bracket (4) with screw (10).

Accompanying drawing 1 is a constructional drawing of the present utility model.

Accompanying drawing 2 is enforcement illustrations of the present utility model.

Now in conjunction with the accompanying drawings 1, accompanying drawing 2 is described as follows:

One end of spring (2) catches on brake pedal (1), and the other end catches on stretching flexible axle (3); The other end of stretching flexible axle (3) catches on the tail end of ratchet (7); Ratchet (7) is movably articulated on the vehicle frame (8) with bearing pin (9); One end of torsion spring (6) catches on the front end of ratchet (7), and the other end colludes on vehicle frame (8); Sour jujube bar (5) is fixed on the seat transition bracket (4) with screw (10).Under normal conditions, because the elastic force effect of torsion spring (6), the claw of ratchet (7) and sour jujube bar (5) are in released state.When depressing brake pedal (1), by with the stretching flexible axle (3) of brake pedal (1) interlock, make the engagement of ratchet (7) and sour jujube bar (5), thus make seat transition bracket (4) and above seat (11) relatively vehicle frame (8) level backward displacement by locking.Spring (2) can make the control run of ratchet (7) not disturb with car brakeing master cylinder (12) control run.

Ratchet of the present utility model (7) and sour jujube bar (5) engagement travel are very little, so, when brake pedal (1) when depressing idle travel, just can realize the seat locking, can not produce the seat locking and lag behind car brakeing.

The utility model is as being used in combination with two-way hanging vibration reduction seat, then can reduce the pitch vibration of various vehicles effectively to chaufeur, in the time of preventing emergency brake of vehicle again by the seat braking retardation that causes of displacement backward, guarantee driving and job safety, and make and install easily, it is few to increase cost.

The utlity model has the advantages such as simple in structure, easy to manufacture, that security is good.

Claims (1)

1. A kind of automatic lock locking apparatus of shock absorbing seat comprises pedal [1], transition bracket [4], it is characterized in that:
