Preferably, the top end of the top plate is fixedly provided with a fixing column, the bottom end of the base is fixedly provided with a fixing column, the top end of the fixing column close to the upper side is fixedly provided with a fixing frame, the bottom end of the fixing column close to the lower side is fixedly provided with a fixing frame, and the center position of the fixing frame is provided with a threaded hole.
Preferably, a bottom valve is arranged inside the base.
Preferably, the inside fixed mounting of support column has flexible loop bar, the central point that the piston rod runs through the support column top puts the bottom that extends to flexible loop bar inside, the inside top position slidable mounting of support column has the shock attenuation disc, the bottom fixed mounting of flexible loop bar has the piston valve.
Preferably, the telescopic sleeve rod comprises a thick sleeve and a thin rod, the bottom end of the thick sleeve is fixedly connected with the piston valve, the thin rod is movably connected with the inner side of the top end of the thick sleeve in a sealing mode, engine oil is filled in the thick sleeve, and a damping sponge is arranged on the outer side of the top end of the telescopic sleeve rod.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model has the advantages that the shock absorber rapidly contracts by the impact force of the conical compression spring to the damping spring, and the phenomena of falling and loosening of the shock absorber caused by overlarge oscillation amplitude are prevented;
2. the utility model can work normally when the device is subjected to large-amplitude oscillation through the cooperation of the piston valve and the bottom valve;
3. the utility model shares the pressure born by the damping spring through the damping sponge, so that the resilience of the damping sponge reduces jolt;
4. the utility model can prevent the piston rod from entering the telescopic loop bar when bearing large pressure due to the fixing of the damping disc, thereby greatly prolonging the service life;
5. the utility model discloses a conical spring protects the up-and-down motion of gum cover, prevents the wearing and tearing phenomenon that the direct contact of roof and support column produced, makes its renewal part more convenient.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1 to 4, the present invention provides an embodiment: the utility model provides a storage battery car back seat buffer of high security, includes base 1, its characterized in that: fixed mounting is put at the central point on base 1 top has support column 2, the central point on 2 tops of support column puts slidable mounting has piston rod 5, the sliding surface of piston rod 5 is connected with conical spring protection gum cover 4, the top fixed mounting of piston rod 5 has roof 6, the outside of support column 2 is equipped with damping spring 3, damping spring 3's one end is connected with roof 6, damping spring 3's the other end is connected with base 1, conical spring protection gum cover 4's inside is equipped with toper compression spring 10.
Further, the top fixed mounting of roof 6 has fixed column 7, and the bottom fixed mounting of base 1 has fixed column 7, and the top fixed mounting that is close to fixed column 7 of top has mount 8, and the bottom fixed mounting that is close to fixed column 7 of below has mount 8, and the central point of mount 8 puts and is equipped with screw hole 9.
Further, a bottom valve 14 is arranged in the base 1, a piston valve 13 is fixedly arranged at the top end of the bottom valve 14, and the piston valve and the bottom valve work in a matched mode to enable the device to work normally even when the device is subjected to large-amplitude oscillation.
Further, the inside fixed mounting of support column 2 has flexible loop bar 12, and piston rod 5 runs through the central point on 2 tops of support column and puts the bottom that extends to flexible loop bar 12 inside, and the top position slidable mounting of 2 inside of support column has shock attenuation disc 11, and shock attenuation disc 11 is fixed, makes the piston rod can not get into the power of flexible loop bar too big when bearing the high pressure, the phenomenon of rupture appears, very big improvement life.
Further, flexible loop bar 12 includes thick sleeve pipe and thin pole, thick sheathed tube bottom and piston valve 13 fixed connection, and the inboard sealed swing joint on thick sleeve pipe top has thin pole, and thick sheathed tube inside is filled has machine oil, and the outside on 12 tops of flexible loop bar is equipped with damping sponge 15, and damping sponge shares the pressure that damping spring bore, makes its resilience reduce jolt.
The working principle is as follows: during the use, pass through screw hole 9 with the device and be connected with electric motor car back seat below, when the electric motor car is through overturning the topography, the electric motor car falls on the ground and conducts the power that produces in the twinkling of an eye and makes it drive piston rod 5 and push down damping spring 3 for roof 6, toper compression spring 10 also receives the power of certain power buffering damping spring 3 simultaneously, piston rod 5 pushes down the bottom to flexible loop bar 10, it begins work to drive bottom valve 14 and the piston valve 13 of bottom plate 1 inside to receive the pressure, make piston rod 5 kick-back, again because the effect of shock attenuation disc 11 and sponge 15, make the power of kick-back reduce, return the normal position until damping spring 3 and conical spring protection gum cover 4, the work is ended.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
