Abstract
The utility model relates to a double-thread releasing screw bolt assembly. The assembly comprises a flat nut (1), a releasing threaded rod and a piercing nut, wherein the flat nut is fixedly connected with the piercing nut through the releasing threaded rod; a section of positive threads and a section of negative threads, which are in tandem connection, are arranged on the releasing threaded rod. The screw bolt provided by the utility model has the benefits that the thread bolt adopts threads where the ratio of the screw pitch of the positive threads M16*1-6h to the screw pitch of the negative threads M16*2-6h-LH being 1 to 2; when cooperating with a piston assembly, the screw bolt can be used for fixing the position between the piston assembly and a cylinder body through bidirectional operation, as a result, the travel of the piston assembly is controlled; the length of the exposed part of the screw bolt is shortened to one third of the original length,and space occupation is greatly saved.
Description
Technical field
The utility model relates to bolt, and particularly a kind of two thread type discharges bolt assembly.
Background technique
Original bolt, when coordinating with piston assembly, can only fix piston assembly and cylinder body position by secondary operation, thereby controls stroke, the long very large space that takies of bolt exposed parts.
Model utility content
The utility model has solved above-mentioned deficiency of the prior art, provides a kind of two thread type to discharge bolt assembly.
The utility model solves the technological scheme that its technical problem adopts: this pair of thread type discharges bolt assembly, comprise flat nut 1, discharge screw rod and capstan nut, flat nut is affixed by discharging screw rod and capstan nut, wherein discharges screw rod and be provided with positive and negative two sections of screw threads of serial connection.
Described positive/negative thread pitch 1:2.
The beneficial effects of the utility model are: this bolt adopts the screw thread of M16 × 1-6h and M16 × 2-6h-LH positive/negative thread pitch 1:2, when coordinating with piston assembly, by bidirectional operation, be fixed piston assembly and cylinder body position, thereby control stroke, and bolt exposed parts shortens to original 1/3, can save very large space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: flat nut 1, discharges screw rod 2, capstan nut 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this pair of thread type discharges bolt assembly, comprises flat nut 1, discharges screw rod 2 and capstan nut 3, and flat nut 1 is affixed with capstan nut 3 by discharging screw rod 2, wherein discharge positive and negative two sections of screw threads that screw rod 2 is provided with serial connection, described positive/negative thread pitch 1:2.This bolt adopts the screw thread of M16 × 1-6h and M16 × 2-6h-LH positive/negative thread pitch 1:2, when coordinating with piston assembly, by bidirectional operation, be fixed piston assembly and cylinder body position, thereby control stroke, and bolt exposed parts shortens to original 1/3, can save very large space.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
