Abstract

The invention relates to the technical field of accessories of automobile seats, in particular to an automobile seat heightening pump. A shell is fixed on a fixing rack and is fastened with a cover via screws, the fixing rack and the shell are respectively provided with corresponding through holes, a toothed shaft is sleeved in the shell, a cylinder is arranged on the upper end surface of the toothed shaft, and rotating teeth are arranged on the lower end surface of the toothed shaft and respectively penetrate through the through holes of the fixing rack and the shell; a toothed disc is sleeved outside the toothed shaft, a disc with a toothed edge is formed on the upper end surface of the toothed disc, a through hole is arranged in the middle of the toothed disc, the cylinder of the toothed shaft penetrates through the through hole of the toothed disc, a handle is sleeved on the cylinder and drives a pawl, a tooth portion is arranged at the front end of the pawl, the rear end of the pawl is riveted on the handle, and the tooth portion of the pawl is meshed with the disc, with the toothed edge, formed on the upper end surface of the toothed disc; and the pawl can drive the toothed disc to rotate by means of rotating the handle, so that the height of a seat is adjusted. Compared with a foreign product, the automobile seat heightening pump is more optimal and simpler in structure, but the service effect of the automobile seat heightening pump is identical to that of the foreign product.

Description

technical field [0001] The invention relates to the technical field of car seat accessories, in particular to a car seat booster pump. Background technique [0002] The existing car seat heightening pump has a mechanism for manual adjustment and electric adjustment. At present, for domestic enterprises, it is still impossible to design a better product. General automobile companies use imported heightening pump products. The technical structure of the heightened pump products is more precise, the product structure is more complicated and the cost is higher. [0003] For the manual height adjustment pump, there is currently only one published patent document with reference value in China, the patent number is "200920071027.4", which discloses a locking mechanism for a manual height adjustment mechanism for a car seat, including a shaft core, Unlocking wheel, fixed ring, lock plate, spring and roller; the lock plate is installed in the fixed ring and can rotate relative to th...
