Abstract
The utility model relates to locking mechanism of an angular modulation governor of a pneumatic spring which is characterized in that an axis of thread of a pneumatic spring piston-rod which is connected with an operated seat is provided with at least one stopping plane wherein a fastener which is connected with the operated seat is on the top of the plane. The utility model avoids relative rotation between the pneumatic spring piston-rod and the operated seat through the fastener thereby connecting safely and reliably and ensuring that the pneumatic spring works reliably. The utility model has simple and reasonable structure and convenient installment. The utility model still increases operating stroke of the pneumatic spring piston-rod and enlarges angle of a back-rest range of regulation thereby offering reliable, reasonable and common angular modulation mechanism for a back support for vehicle seats and the like with angular adjustment.
Description
Technical field
The utility model relates to a kind of retaining mechanism of backrest angle demodulator, especially a kind of retaining mechanism of vehicle seat back air spring angle regulator.
Background technology
The retaining mechanism of present disclosed air spring angle regulator is that the air spring piston rod is screwed in the screwed hole of handling seat, and the locking of its screw thread is to rely on locking nut to realize.But in use,, locking nut is axially moved forward and backward, cause air spring work malfunctioning, so functional reliability is poor owing to be subjected to vibration, the assembling of vehicle in travelling tightly not reach factors such as chair angle adjusting.Because locking nut has taken the impulse stroke of air spring piston rod, also make the impulse stroke of air spring piston rod shorten simultaneously, not only limited the backrest angle adjustable range, and limited the performance and the quality of air spring.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of safe and reliable, and can increase the retaining mechanism of the air spring angle regulator of air spring piston rod impulse stroke.
Technical problem to be solved in the utility model realizes by following technical proposal: a kind of air spring angle regulator locking, it is characterized in that: the plane with having a retaining on manipulation its thread spindle of air spring piston rod that is connected at least is connected the securing member of handling seat and withstands on this plane.
After adopting technique scheme, after handling being connected of seat and air spring piston rod, withstand on by a securing member on the plane of air spring piston rod thread axle, prevent air spring piston rod and the mutual rotation of handling seat in the work, thoroughly stopped to handle seat and be connected insecure problem with the air spring piston rod, guaranteed the functional reliability of air spring, not only simple in structure, rationally, and it is easy for installation, the locking nut of air spring piston rod has simultaneously gone to disappear, increased the impulse stroke of air spring piston rod and the scope that backrest angle is regulated, and can be by increasing the axial dimension of air spring, to improve air spring performance and quality.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is an another kind of structural representation of the present utility model.
Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment
The retaining mechanism of air spring angle regulator of the present utility model shown in Fig. 1,3, comprise the air spring assembly of forming by air spring screw rod, cylinder body 1-2 and air spring piston rod 1-1 1 and handle seat 3, the thread spindle of air spring piston rod 1-1 front portion is screwed in the screw of handling seat 3, handle 4 hinges of spanner in handling seat 3, handle the flexible of spanner 4 control air spring valve rods by moving.As shown in Figure 1, 2, one side is provided with the plane 1-3 of retaining on the thread spindle of air spring piston rod 1-1, and a securing member 2 is screwed in the screwed hole of handling seat 3, and its bottom withstands on the plane 1-3 of air spring piston 1-1 thread spindle; The retaining mechanism of the utility model air spring angle regulator also can be installed for convenient shown in Fig. 3,4, and the retaining plane 1-3 of air spring piston 1-1 thread spindle can be symmetrical arranged.The utility model can make by securing member 2 and handle seat 3 and can not produce relative rotation at work with air spring piston rod 1-1, so connection reliability, simple in structure, not only can guarantee the air spring functional reliability, and increase the impulse stroke of air spring piston rod 1-1.
Claims (2)
1, a kind of retaining mechanism of air spring angle regulator, it is characterized in that: with handle its thread spindle of air spring piston rod (1-1) that seat (3) is connected on have the plane (1-3) of a retaining at least, be connected a securing member (2) of handling (3) and withstand on this plane (1-3).
2, the retaining mechanism of air spring angle regulator according to claim 1 is characterized in that: described plane (1-3) can be symmetricly set on the two sides of air spring piston rod (1-1) thread spindle.
