The engineering truck seat with the shock absorption device comprises a baseboard (1); a seat cushion (2) is arranged on the baseboard; and a backrest (3) is arranged at one end of the seat cushion. The engineering truck seat with the shock absorption device is characterized in that: shock absorption sheets (4) are fixed at the lower parts of the front and rear ends of the seat cushion (2); the shock absorption sheets are hinged with fixed sheets (5) which are fixed on the baseboard; and the lower part of the seat cushion (2) is connected with a buffer spring (6).
Description
Technical field
The utility model relates to a kind of engineering truck seat, especially relates to a kind of engineering truck seat with shock absorption device.
Background technology
Continuous progress and development along with society, main tool when heavy engineering vehicle day becomes to becoming people and carries out operation, but the engineering truck seat of engineering truck use at present, when carrying out operation or transportation, ubiquity is owing to engineering truck seat and body contact insufficient strength or cushion frame insufficient rigidity, situation about meeting accident easily.Chinese patent discloses a kind of automotive seat, and (Granted publication number: CN 201240297Y), it comprises the chair back, and the chair back comprises side board, and last side plate and headrest, seat also are provided with induction tailstock impulsive force and make the device of headrest to driving staff's head movement; Device comprise be arranged on described chair back top and with the chair back flexibly connect lean against stay bearing plate and with the last bindiny mechanism that leans against stay bearing plate and rest the head on and captive joint; Device also comprises the connecting rod that two side stands of captiveing joint with the both sides of side board respectively and an end and side stand flexibly connect; The other end of connecting rod with lean against stay bearing plate and flexibly connect; The bottom that leans against stay bearing plate also is provided with the following bindiny mechanism that flexibly connects with side board; Last bindiny mechanism be two two ends respectively with lean against stay bearing plate and headrest and captive joint and pass the headrest guide pipe of side plate; The top of last side plate is provided with and the cooresponding groove of the guide pipe of resting the head on; One end of connecting rod and side stand are hinged by shoulder bolt, the other end of connecting rod with lean against stay bearing plate and flexibly connect by rotating pin and jam nut; Following bindiny mechanism is that two ends are respectively with side board with lean against stay bearing plate bonded assembly elastic element; The headrest guide pipe passes the side plate place and is coated with buffer bush; Be provided with lining between connecting rod and the shoulder bolt; Rotating pin and lean against to be provided with between the stay bearing plate and add long bushing; Elastic element be two respectively with side board with lean against stay bearing plate bonded assembly spring.But because engineering truck is in transportation or during operation, vehicle body can produce vibrations, and this automotive seat do not have shock absorption device at the seat cushion place, and therefore the shaking force that human body is produced is bigger, influences the operation of people to automobile.
The utility model content
The utility model provides a kind of engineering truck seat with shock absorption device, it mainly is to solve the existing in prior technology engineering truck when transportation or operation, vehicle body can produce vibrations, existing engineering truck seat does not have shock absorption device at the seat cushion place, therefore the shaking force that human body is produced is bigger, influences the technical matters of people to the operation of engineering truck etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The engineering truck seat of band shock absorption device of the present utility model comprises base plate, and base plate is provided with seat cushion, seat cushion one end is provided with backrest, and the bottom of described seat cushion rear and front end is fixed with vibration damping sheet, and vibration damping sheet is hinged with fixed plate, fixed plate is fixed on the base plate, and the seat cushion bottom is connected with recoil spring.Vibration damping sheet can be swung on fixed plate slightly, and recoil spring can absorb impulsive force, the vibrations that bring in the time of can alleviating the engineering truck operation like this.
As preferably, be provided with dust boot between described base plate and the seat cushion.The seat cushion bottom is owing to install shock absorption device, so leaves the gap between itself and the base plate, this gap can be sealed by dust boot, played antisoiling effect on the one hand, prevents from also on the other hand that human body from entering between base plate and the seat cushion to be crushed.
As preferably, described seat cushion bottom is provided with the operating knob of contact-carrying, and the contact of operating knob bottom has drag hook, drag hook is connected on the spring, spring is connected with movable contact spring, and the upper and lower of movable contact spring end is respectively equipped with normally closed interlock, normally open contact, and contact connects electric lock by circuit.After seat cushion presses down, the required action that presses down of electrical sensation, drag hook loses pulling force, and spring promptly can resilience, thereby makes movable contact spring contact normally open contact, makes contact and electric lock conducting, the engineering truck startup of can unblanking.Can prevent that like this engineering truck from starting automatically because of accident, avoid causing safety misadventure.
As preferably, the outside face of described seat cushion, backrest is provided with the plastic uptake sponge.The plastic uptake sponge is that vacuum foaming one-shot forming is made, and has high resilience.
As preferably, be connected with the backrest angle regulating handle on the described backrest, can regulate the angle of backrest as required.
As preferably, described base plate lower surface is fixed with slide rail, and slide rail is connected with the front and back position regulating handle.Slide rail can slide on engineering truck, thereby adjusts the spacing of seat and operator's station.
As preferably, described seat cushion is provided with body weight and regulates roller, can adjust the height of seat cushion.
Therefore, the utility model increases shock absorption device in the bottom of engineering truck seat cushion, when engineering truck is subjected to impacting, can play the effect of damping, buffering,, can play only to be sitting on the seat cushion and could start engineering truck in addition by electric lock, avoid causing safety misadventure, simple and reasonable for structure.
