Abstract
The utility model relates to an automotive air spring antiskid device which comprises an antiskid seat, an antiskid sleeve, an elastic piece and a plug pin. The antiskid seat is a cylinder body, a through hole is arranged in the middle of the antiskid seat, the outer circle of the cylinder body is in a step shape, and two pin holes where location pins are installed are symmetrically arranged on the outer circle. The antiskid sleeve is a round tube, a notch is arranged at one end of the round tube, and the antiskid sleeve is sleeved on the antiskid seat and respectively located through two location pins. The elastic piece is installed on an inclined groove of the antiskid seat. When an air spring is in a complete folding state, the antiskid sleeve can swing outwards under the elasticity of the elastic piece, and the notch of the antiskid sleeve can be clamped on an air spring cylinder to effectively prevent a car cover form gliding downwards due to failure of the air spring. The automotive air spring antiskid device is simple and practical in structure and widely applied to heavy excavators.
Description
Technical field
The utility model relates to a kind of safety guard of gas spring for automobile, especially the anti-skid device of gas spring for automobile.
Background technology
When repairing or checking the engine of excavating machine, must open bonnet.After gas spring struts bonnet, because of its bonnet is roomy and heavy, in case gas spring lost efficacy or will inevitably cause the lifting force decay of gas spring the downward landing of bonnet, thereby just have serious potential safety hazard because of the long-term use of gas spring causes.
Summary of the invention
The purpose of the utility model just provides a kind of safety guard of gas spring for automobile, i.e. the anti-skid device of gas spring for automobile.
The main technical schemes of the utility model is following:
A kind of gas spring for automobile anti-skid device, it comprises Anti-skid seat, anti-sliding sleeve, shell fragment and two locating dowel pins that are installed in Anti-skid seat cylindrical and symmetry.It is step-like cylinder that said Anti-skid seat has a through hole, cylindrical in the middle of being, on the cylindrical of Anti-skid seat, is provided with two pin-and-holes symmetry, that be used for the installing and locating pin.Anti-skidding being sleeved on the Anti-skid seat located respectively through two locating dowel pins.Anti-sliding sleeve is a pipe, and an end of anti-sliding sleeve is with a breach.Shell fragment is to have a certain degree in its total length 1/3rd places bending, and is contained on the skewed slot of Anti-skid seat.
The relative Anti-skid seat of said anti-sliding sleeve axle center certain angle that can swing.
Said shell fragment can be with preventing the certain angle of sliding sleeve swing because of its elasticity that has.
Said when gas spring is in the full extension state, be sitting on the gas spring through the breach card of preventing sliding sleeve, can effectively prevent to come off because of the inefficacy of gas spring.
Having the following advantages of the utility model: when gas spring is in the full extension state; Because of its shell fragment rubber-like effect; Impel anti-sliding sleeve outwards to swing, its breach card is sitting on the gas spring cylinder barrel, can prevent effectively to cause the downward landing of car bonnet because of the inefficacy of gas spring.The utility model is simple and practical, can be widely used on the heavy digger at present.
Description of drawings
Fig. 1 is the structural representation of the utility model when the gas spring extended configuration.
Fig. 2 is the structural representation of the utility model when the gas spring compressive state.
Being numbered of each parts in the accompanying drawing:
1, gas spring joint; 2, Anti-skid seat; 3, locating dowel pin; 4, shell fragment; 5, anti-sliding sleeve; 6, piston rod; 7, gas spring.
The specific embodiment:
As shown in the figure, a kind of gas spring for automobile anti-skid device is contained on the head of piston rod 6 of gas spring, screws with gas spring joint 1.The gas spring for automobile anti-skid device, it comprises Anti-skid seat 2, anti-sliding sleeve 5, shell fragment 4 and two locating dowel pins 3 that are installed in Anti-skid seat 2 cylindricals and symmetry.It is step-like cylinder that Anti-skid seat 2 has a through hole, cylindrical in the middle of being, on the cylindrical of Anti-skid seat 2, is provided with two pin-and-holes symmetry, that be used for the installing and locating pin; Two locating dowel pins 3 are installed on the Anti-skid seat 2 with the mode symmetric mode of interference fit.Shell fragment 4 is to have a certain degree in its total length 1/3rd places bending, and is contained on the skewed slot of Anti-skid seat 2.Anti-sliding sleeve 5 is contained on the Anti-skid seat 2, locatees respectively through two locating dowel pins 3; Anti-sliding sleeve 5 is pipes, is with a breach at an end of preventing sliding sleeve 5.
When gas spring was in the state of full extension, because the elastic reaction of shell fragment 4, anti-sliding sleeve 5 was the axle center with locating dowel pin 3, nature swing certain angle left, the breach card of anti-sliding sleeve 5 bottoms is sitting on the gas spring 7.When needs close bonnet, that is when needing gas spring to be in the state of full extension, at first, promote the anti-sliding sleeve 5 of anti-skidding safety device to the right with hand, the endoporus of anti-sliding sleeve 5 is aligned gas spring, the breach of anti-sliding sleeve 5 can be stuck on the gas spring 7.The second, close bonnet one segment distance, promptly shortly past the position of preventing sliding sleeve 5 breach.At last, bonnet is closed fully.
