Abstract

The utility model relates to an armchair angular modulation governor of a pneumatic spring which is operated horizontally comprising a main assemblage of spring, an operated seat and an operated spanner. The utility model is characterized in that a whorl hole of the operated seat is provided with a notch, wherein the operated seat is connected with the pneumatic spring piston-rod. A boot-shaped and rotary block is hinged with the inside of the notch of the operated seat wherein the back of the boot-shaped and rotary block is a valve handle of the pneumatic spring, the operated spanner which is provided horizontally is hinged on branch auricular of the operated seat and is provided on the boot upper of the boot-shaped and rotary block. The operated spanner which is on the operated seat hinged horizontally is thrown up and down thereby the boot-shaped and rotary block rotating specified angle controls telescopic motion of the valve handle of the pneumatic spring. Above all, the operated spanner which is provided horizontally achieves adjustable function of armchairs and is applied in armchairs with horizontal space.

Description

The air spring angle regulator of lateral operation

Technical field

The utility model relates to a kind of backrest angle demodulator, especially a kind of air spring angle regulator of lateral control.

Background technology

Known air spring angle regulator, mostly by air spring assembly, the manipulation seat that is connected with seat and be arranged on a manipulation spanner of handling in the seat and form, it handles spanner, and generally all the axial direction with the air spring assembly is identical, be vertical setting, when the adjustment seat chair back, flexible by moving manipulation spanner control air spring valve rod, so the air spring angle regulator of this kind structure generally can only be applicable to the seat that certain space is vertically arranged, then can not be suitable for for the seat of inconvenience in vertically operation.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of spanner of handling can be horizontally installed on the air spring angle regulator of handling on the seat.

Technical problem to be solved in the utility model realizes by following technical proposal: a kind of air spring seat angle regulator of lateral operation, comprise the air spring assembly, handle seat and handle spanner, it is characterized in that: the manipulation seat screw rear portion that is connected with the air spring piston rod has notch, the boot-shaped gyration block is hinged in the notch of handling seat, the back of boot-shaped gyration block and air spring valve rod join, and the manipulation spanner of horizontally set is hinged on the journal stirrup of handling seat and is arranged on the boot upper of boot-shaped gyration block.

After adopting technique scheme, because being hinged on, boot-shaped gyration block one end handles on the seat, the boots back of the body joins with the air spring valve rod, its boot upper joins with the manipulation spanner, move up and down by the manipulation spanner that horizontal hinge is handled on the seat, the boot-shaped gyration block is rotated a certain angle control the stretching motion of air spring valve rod, but therefore horizontally set is handled the regulatory function that spanner is realized seat, be applicable to the seat of horizontal space.

The specific embodiment

As Fig. 1, the air spring angle regulator of lateral control of the present utility model shown in 2, comprise by air spring cylinder body 1-2 and air spring piston rod 1-1, the air spring assembly 1 that air spring valve rod 1-3 etc. form, the front portion of air spring piston rod 1-1 has screw thread, and be screwed in the screw of handling seat 5, for preventing air spring piston rod 1-1 and handling relatively rotating of seat 5, also be provided with locking nut 2 on the air spring piston rod 1-1, have notch 5-1 at manipulation seat 5 screw rear portions, one boot-shaped gyration block 3 is hinged in the notch 5-1 that handles seat 5 by pivot pin, the back of boot-shaped gyration block 3 and air spring valve rod 1-3 join, the manipulation spanner 4 of horizontally set is hinged on the journal stirrup 5-3 that handles seat 5 and is arranged on the boot upper of boot-shaped gyration block 3, for dwindling manipulation space, it is handled spanner 4 and can be " L " shape, handle spanner 4 by moving up and down, make the stretching motion of boot-shaped gyration block 3 control air spring valve rod 1-3.Handle spanner 4 control positions for controlling exactly, the dual-side of notch 5-1 is provided with stopper slot 5-2.

It shown in Fig. 3,4 the air spring angle regulator of another kind of lateral control of the present utility model, its structure is substantially identical with Fig. 1,2 structures, its difference is that air spring piston rod 1-1 and the retaining mechanism of handling seat 5 adopt locking shell fragment 6, there is back stop slot at air spring piston rod 1-1 screw thread rear portion, one end of locking shell fragment 6 is arranged in the back stop slot 1-3, the opposite side of locking shell fragment 6 then is fixedly connected on by securing member 7 and handles on the seat 5, makes air spring piston rod 1-1 and handles seat 5 reliable lock by locking shell fragment 6.

As Fig. 5, it shown in 6 the air spring angle regulator of the lateral control of another structure of the present utility model, its structure is basic identical with above-mentioned two kinds of structures, its difference is that air spring piston rod 1-1 and the locking of handling seat 5 adopts a securing member 8, air spring piston rod 1-1 thread spindle is provided with the plane 1-4 of retaining, one securing member 8 is connected on the manipulation seat 5 and withstands on the 1-4 of this plane, as shown in Figure 7, also can on the thread spindle of air spring piston rod 1-1, be arranged with the plane 1-4 of retaining, to prevent air spring piston rod 1-1 and to handle seat 5 and rotate in that the course of work is relative, so connect reliably, can guarantee the functional reliability of air spring.
