Abstract
The utility model discloses a screw rod of a bottom valve for an automobile shock absorber. The screw rod of the bottom valve for the automobile shock absorber comprises a hexagon screw head and a cylindrical screw rod body, and at the connection position of the screw rod body and the hexagon screw head, an annular groove is arranged on the hexagon screw head along the circumference of the root portion of the screw rod body. The included angle between the outer wall of the groove and an end face of the hexagon screw head is 45 degrees. The screw rod of the bottom valve for the automobile shock absorber is simple in structure and reasonable in design, the effect that the end face of the hexagon screw head tightly contacts a baffle plate of the bottom valve in a fit mode can be guaranteed, oil leakage can be prevented from happening, and functions of the bottom valve which comprises a compression valve assembly and a compensation valve assembly can be well achieved.
Description
Technical field
The utility model relates to a kind of screw rod, particularly relates to a kind of vehicle shock absorber bottom valve screw rod.
Background technique
Such as Fig. 1, Fig. 2 and shown in Figure 3, in vehicle shock absorber, bottom valve screw rod 1 is made of hexagonal screw rod head 12 and cylindrical screw column 11.The major function of bottom valve screw rod 1 is that bottom valve screw rod 1 passes bottom valve baffle plate 2 and foot valve seat 3 cooperates with bottom valve nut 4, thereby realizes the fixing of sub assembly of bottom valve, and the throttle functionality of sub assembly of bottom valve and recuperation valve function are achieved.The problem that exists at present is: be a vertical surface between the screw column 11 of existing bottom valve screw rod 1 and hexagonal screw rod head 12 end faces, when hexagonal screw rod head 12 end faces of bottom valve screw rod 1 match with bottom valve baffle plate 2, can fit between them not tight, can form gap a, thereby causing sub assembly of bottom valve that fluid easily occurs in the course of the work reveals, vibration damper compression damping value conformity is relatively poor, affects compression valve and the recuperation valve function of sub assembly of bottom valve.
The model utility content
The purpose of this utility model just provides a kind of vehicle shock absorber bottom valve screw rod, can guarantee to fit closely between hexagonal screw rod end surface and the bottom valve baffle plate, prevents fluid and reveals, and the compression valve of sub assembly of bottom valve and recuperation valve function are better realized.
The purpose of this utility model realizes by following technical proposals:
A kind of vehicle shock absorber bottom valve screw rod comprises hexagonal screw rod head and cylindrical screw column, at the link position of screw column and hexagonal screw rod head, offers circular groove along screw column root circumference at the hexagonal screw rod head.
Further, the angle between described groove outer wall and the hexagonal screw rod end surface is 45 °.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, reasonable in design, can guarantee to fit between hexagonal screw rod end surface and the bottom valve baffle plate closely, prevent fluid and reveal, the compression valve of sub assembly of bottom valve and recuperation valve function are better realized.
Description of drawings
Fig. 1 is the structural representation of prior art bottom valve screw rod;
Fig. 2 is the structural representation of sub assembly of bottom valve;
Fig. 3 is the partial enlarged drawing at A place among Fig. 2;
Fig. 4 is structural representation of the present utility model;
Fig. 5 is the partial enlarged drawing at B place among Fig. 4.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 4 and Figure 5, a kind of vehicle shock absorber bottom valve screw rod comprises hexagonal screw rod head 12 and cylindrical screw column 11, at the link position of screw column 11 with hexagonal screw rod head 12, offers circular groove 13 along screw column 11 root circumference at hexagonal screw rod head 12.Angle b between described groove 13 outer walls and hexagonal screw rod head 12 end faces is 45 °.
Structure of the present utility model, clear the screw column 11 back chipping mode with 12 transition of hexagonal screw rod head, guarantee the conformity of parts machining, and can guarantee to fit between hexagonal screw rod head 12 end faces and the bottom valve baffle plate closely, prevent fluid and reveal, the compression valve of sub assembly of bottom valve and recuperation valve function are better realized.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
