Abstract

The utility model relates to a lifting chair with a chair seat which can move back and forth, in particular to a supporting seat relating to the lifting chair. The supporting seat comprises a base, a sliding plate and a handle for locking the sliding plate; the handle for locking the sliding plate is arranged on the base; the sliding plate is movably and directly arranged on the surface of the base; a resetting device is also arranged between the sliding plate and the base; more than two positioning holes are arranged on the sliding plate; and the locking end of the handle for locking the sliding plate moves on the sliding plate back and forth for a certain distance, can be embedded into the corresponding positioning hole, and locks the sliding plate. The supporting seat has simple and reasonable structural design; a bottom cover is removed, and the sliding plate is directly arranged on the surface of the base, thereby greatly reducing the cost of the supporting seat; the sliding plate is also convenient to be mounted, which further reduces the cost of the lifting chair; the handle for locking the sliding plate is arranged on the side of the base so as to make the structure of the supporting seat more compact, reduce the mounting height of the chair seat, and increase the adjusting range in height simultaneously.

Description

The supporting seat of chair lift

Technical field

The utility model relates to the chair lift that a kind of seat support can move forward and backward, and specifically relates to the supporting seat of this kind chair lift.

Background technology

A kind of chair lift is arranged now, and its seat support can move forward and backward, and the supporting seat that supports this seat support comprises base, be fixed on the bottom on the susceptor surface, with the slide plate that bottom is slidingly connected, seat support is installed on the slide plate, and the slide plate lock handle is installed on the bottom, owing on the bottom slide lock handle will be installed, therefore bottom is thicker, causes seat position higher, uses inconvenient, and cost is also high, has increased the installation procedure of supporting seat.

Summary of the invention

Therefore, the purpose of this utility model is to provide a kind of cost low, simple in structure and increase the supporting seat of the chair lift of the adjustable range of seat support on short transverse.

To achieve these goals, the utility model adopts following technical proposals:

A kind of supporting seat of chair lift, comprise a base that is installed in elevating lever upper end, slide plate that is connected with seat support and slide plate lock handle, described slide plate lock handle is installed on the base, the slide plate activity be directly installed on susceptor surface, also be provided with resetting means between slide plate and the base, slide plate is provided with plural locating hole, and the locking termination of slide plate lock handle can embed after slide plate moves forward and backward certain position and lock slide plate in the positioning hole corresponding.

In order better to realize above-mentioned purpose, technique scheme also can be done following further perfect:

Described slide plate and base are respectively equipped with four rectangular grooves and four bolts hole, rectangular groove extends along the direction that moves forward and backward of seat support, bolt hole and rectangular groove are corresponding one by one up and down and be provided with bolt within it, the bolt two ends are provided with nut and along bolt axial compression slide plate and base, described locating hole moves forward and backward the direction setting along seat support.

Described resetting means is a back-moving spring, and back-moving spring one end is hooked on the base, and the other end is hooked on the slide plate.

The utility model structural design advantages of simple, remove bottom, slide plate is directly installed on susceptor surface, greatly reduce the cost of supporting seat, slide plate is installed also convenient, has further reduced the cost of chair lift, the slide plate lock handle is installed in the base side, make clamping support compact more, reduced the setting height(from bottom) of seat support simultaneously, increased its adjustable range in short transverse.
