lift seat

Abstract

The invention discloses a lifting seat. The lifting seat comprises a base and a supporting rod for connection with a seat plate, wherein the supporting rod is connected to the base along the verticaldirection in a sliding manner; the base is internally provided with a hollow cavity for sliding of the supporting rod; a ring-shaped bulge is arranged on the inner wall of the hollow cavity, partitions the hollow cavity into an upper cavity and a lower cavity, and is provided with a through hole for penetration of the supporting rod; the lower end of the supporting rod is rotatably connected witha swinging plate by a first hinging point, a first stopper and a second stopper for abutting against or separating from the bottom part of the lower cavity are arranged at the bottom part of the lowercavity and at the two ends of the swinging plate, the two ends of the swinging plate are respectively connected with the base by a first pulling spring and a second pulling spring, the stiffness coefficients of the first pulling spring and the second pulling spring are not equal, and one side with low stiffness coefficient on the supporting rod is provided with a clamping pin. The lifting seat disclosed by the invention has the beneficial effects that the structure is simple, the safety coefficient is improved and the bearing capability is high.

Description

technical field [0001] The invention relates to a lifting seat. Background technique [0002] The lifting seat is a kind of chair for people to sit on. Its characteristic is that the height of the seat plate on the seat can be adjusted. The seat plate is slid and connected to the base along the vertical direction. The sitting height relative to the ground. The key of a lifting seat lies in its mechanism for adjusting the height of the seat plate. In the prior art, there are various types and forms of such height-adjusting mechanisms; among them, the most commonly used structure is between the seat plate and the base. Set the cylinder, and then people can automatically change the height of the seat plate according to their weight after sitting on the seat plate. This type of lift seat has a greater safety hazard, and it is easy to cause the seat plate and the base to suddenly separate or even burst due to the aging of the cylinder. Then cause personal injury to the occupant...

The key of a lifting seat lies in its mechanism for adjusting the height of the seat plate. In the prior art, there are various types and forms of such height-adjusting mechanisms; among them, the most commonly used structure is between the seat plate and the base. Set the cylinder, and then people can automatically change the height of the seat plate according to their weight after sitting on the seat plate. This type of lift seat has a greater safety hazard, and it is easy to cause the seat plate and the base to suddenly separate or even burst due to the aging of the cylinder. Then it will cause personal injury to the occupants; in addition, the height adjustment of the seat plate is realized by setting a transmission mechanism between the seat plate and the base. This type of lift seat often causes inconvenient adjustment due to the complicated structure of the transmission mechanism.

Generally speaking, the lifting seats in the prior art generally have the disadvantages of complex structure, insufficient safety factor and low carrying capacity
