Abstract
The utility model discloses a kind of screw retention jump ring, comprise stud and nut; Described nut screws in stud one end; The upper-end surface of described stud has a horizontal straight trough, and the upper-end surface of described nut has three uniform horizontal straight troughs; Jump ring is embedded with inside the horizontal straight trough of described stud and nut upper-end surface; Described jump ring is G type structure.Screw retention jump ring of the present utility model, structure is simple, with low cost, curves diagram shape with Spring Steel Wire; Install jump ring by the horizontal straight trough fit inside of stud and nut upper-end surface, anti-loosing effect is good.
Description
Technical field
The utility model relates to a kind of screw retention jump ring, belongs to piston spiral shell technical field.
Background technique
Being threaded in engineering goods is the connection of most extensive use, but it is in use because vibration, the reason such as loose always have loosening phenomenon; Connect to loosen and will cause serious consequence; In prior art, the axial pre tightening force produced when threaded fastener is by tightening realizes, in strenuous vibration, this pretightening force reduces will cause loosening gradually, the form of bolt looseness has three kinds of forms such as horizontal transposition, transverse translation and axial strain, these loosening forms all can cause the displacement between screw thread or between nut and supporting surface, namely from the appearance of loose phenomenon; China Patent No.: 201210478033.8 disclose a kind of piston blot jump ring, comprise stud, nut and jump ring, jump ring is fixed on stud by nut, is connected between piston top and piston skirt by stud with pin, loosen for preventing stud, stud is provided with spring jump ring, inventive piston screw jump ring, and technique is simple, easy for installation, with low cost, structure is simple, anti-loosening effective; The jump ring of technique scheme is fixed on stud by nut, carries out spacing, but this type of mode stability is inadequate, easily causes disengaging.
Model utility content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of screw retention jump ring, be installed on by jump ring on stud and nut simultaneously; Ensure that it is not easy to depart from.
(2) technological scheme
Screw retention jump ring of the present utility model, comprises stud and nut; Described nut screws in stud one end; The upper-end surface of described stud has a horizontal straight trough, and the upper-end surface of described nut has three uniform horizontal straight troughs; Jump ring is embedded with inside the horizontal straight trough of described stud and nut upper-end surface; Described jump ring is G type structure.
As preferred embodiment, jump ring can directly be curved by Spring Steel Wire.
Further, described stud two ends are installed between piston top and piston skirt respectively.
As preferred embodiment, the horizontal straight trough of described stud upper-end surface can be T-type structure.
(3) beneficial effect
Compared with prior art, screw retention jump ring of the present utility model, structure is simple, with low cost, curves diagram shape with Spring Steel Wire; Install jump ring by the horizontal straight trough fit inside of stud and nut upper-end surface, anti-loosing effect is good.
Accompanying drawing explanation
Fig. 1 is partial axial section structural representation of the present utility model;
Fig. 2 is clip spring structure schematic diagram of the present utility model.
Embodiment
A kind of screw retention jump ring as depicted in figs. 1 and 2, comprises stud 1 and nut 2; Described nut 2 screws in stud 1 one end; The upper-end surface of described stud 1 has a horizontal straight trough (not shown), and the upper-end surface of described nut 2 has three uniform horizontal straight troughs 3; Jump ring 4 is embedded with inside the horizontal straight trough of described stud 1 and nut 2 upper-end surface; Described jump ring 4 is G type structure.
Wherein, described jump ring 4 can directly be curved by Spring Steel Wire; Described stud 1 two ends are installed between piston top and piston skirt respectively; The horizontal straight trough of described stud 1 upper-end surface can be T-type structure.
Screw retention jump ring of the present utility model, structure is simple, with low cost, curves diagram shape with Spring Steel Wire; Install jump ring by the horizontal straight trough fit inside of stud and nut upper-end surface, anti-loosing effect is good.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
