Description

Technical Field

[0001] The utility model relates to the technical field of seat slide rails, in particular to a high-load engineering vehicle seat slide rail. Background Art

[0002] High-load engineering vehicle seat slides are a device used to adjust the seat position, usually consisting of an upper rail and a lower rail. The lower rail is installed on the ground of the engineering vehicle, and the upper rail is connected to the seat. The position of the seat is adjusted by sliding the upper and lower rails. The ability to withstand heavy loads needs to be considered when designing this slide system, because the seats of engineering vehicles often need to bear heavier loads.

[0003] For example, a Chinese patent discloses "a shock absorbing device for a construction vehicle seat" (patent publication number: CN110203114A), which includes a base plate and a shock absorbing device. The shock absorbing device is located below the base plate, a cushion is fixedly installed on the top of the base plate, a slide rail is fixedly installed on the bottom of the shock absorbing device, armrests are fixedly installed on both sides of the top of the base plate, and a movable seat is fixedly installed on one side of the base plate. The shock absorbing device for a construction vehicle seat can improve the shock absorbing effect of the construction vehicle seat, and the shock absorbing effect can be effectively enhanced by the cooperation of the gear and the gear rod. The above patent has the advantage of improving the comfort of the user.

[0004] However, the above-mentioned seat shock absorbing device is difficult to prevent the seat slide rail from being squeezed and deformed due to excessive load on the slide rail by the seat, and the locking failure. Therefore, a seat slide rail that can improve the safety of the engineering vehicle seat slide rail is needed. Utility Model Content
