Abstract
The utility model discloses an antiskid self-locking sleeve, comprising a cylinder body (1). The cylinder body (1) is provided with a handle connecting port (2); the cylinder body (1) is internally provided with a sleeve chamber (5) which is internally provided with at least two symmetrical eccentric arcs (8) which are provided with eccentric threads corresponding to the eccentric arcs; the upper end surface and the lower end surface of the eccentric threads (6) are provided with arc concave troughs (4) which are internally provided with cirque springs (3); the lower port of the sleeve chamber (5) is provided with a clip (7) which blocks the eccentric threads (6) which are provided with teeth (9). By adopting the structure, under the torsion action, the eccentric threads (6) are rotated along the eccentric arc (8); the internal chamber formed by the eccentric threads (6) is contracted, which leads the teeth (9) to be tightly engaged with screws or screw caps in order to implement automatic locking; because the internal chamber formed by the eccentric threads (6) reduced in the torsion, one specification can be suitable for screws with two through three specifications; the utility model has the advantages of simple and dense structure, smart and convenient application, multipurpose with one part, long service life, etc.
Description
One, technical field
The utility model relates to a kind of sleeve, particularly a kind of anti-skidding self-tightening sleeve that sleeve can the auto lock screw when dismantling screw.
Two, background technology
Now sleeve that uses or double offset ring spanner all are that a kind of specifications and models can only be used for dismantling or tighten the screw with a kind of specifications and models, can not use one more; If dismounting or the screw hexagonal (hexagon)nut of tightening wear and tear to some extent, just be easy to generate during operation and skid, give and install or repair and bring difficulty and inconvenience, thereby influence operating efficiency and work quality.After sleeve or double offset ring spanner wearing and tearing, equally also can produce above defective.
Three, summary of the invention
In order to overcome existing sleeve or the double offset ring spanner specifications and models are many, the disadvantage of skidding easily when using, the utility model provides the anti-skidding self-tightening sleeve of a kind of energy auto lock and applicable plurality of specifications model.The invention solves the technical scheme that its technical problem adopts and comprises cylindrical shell, cylindrical shell is provided with the handle connector, be provided with the sleeve cavity in simplified, the eccentric arc of at least two symmetries is set in the sleeve cavity, on eccentric arc, be provided with corresponding with it eccentric bolt die, the upper and lower end face of eccentric bolt die is provided with arc groove, and ring spring is set in the arc groove, and the end opening of sleeve cavity is provided with buckle and blocks eccentric bolt die; Eccentric bolt die is provided with teeth.After adopting said structure, eccentric bolt die is under twisting force, and eccentric bolt die rotates along the eccentric arc in the sleeve cavity, and the inner chamber that eccentric bolt die is formed further dwindles, and makes teeth tightly bite screw or nut, realizes auto lock; Because the inner chamber that eccentric bolt die is formed when reversing dwindles, a specification just can be suitable for the screw or the nut of two to three specifications; Have simple and compact for structure, flexible and convenient to use, more than one with advantages such as, life-span are long.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Figure 1A-A cross-sectional view.
Five, the specific embodiment
Illustrated in figures 1 and 2, specific embodiments for a kind of anti-skidding self-tightening sleeve of the utility model, it comprises cylindrical shell 1, cylindrical shell 1 is provided with handle connector 2, be provided with sleeve cavity 5 in the cylindrical shell 1, the eccentric arc 8 of four symmetries is set in the sleeve cavity 5, on eccentric arc 8, be provided with corresponding with it eccentric bolt die 6, the upper and lower end face of eccentric bolt die 6 is provided with arc groove 4, ring spring 3 is set in the arc groove 4, the end opening of sleeve cavity 5 is provided with buckle 7 and blocks eccentric bolt die 6, and eccentric bolt die 6 is provided with teeth 9.
Its course of work is as follows: at first entangle screw or nut with the utility model, screw that requirement is rotated or nut diagonal can block eccentric bolt die 6 and get final product, under twisting force, eccentric bolt die 6 rotates along the eccentric arc 8 in the sleeve cavity 5, the inner chamber that eccentric bolt die 6 is formed further dwindles, make teeth 9 tightly bite screw or nut, reach auto lock; By the time after dismantling or tighten screw or nut and unclamping, eccentric bolt die 6 automatically resets under the effect of ring spring 3.The inner chamber of forming owing to eccentric bolt die 6 when reversing is along with the increase of the anglec of rotation is dwindled, so just can use as long as screw or nut diagonal can block eccentric bolt die 6, a specification can be suitable for the screw or the nut of two to three specifications, and existing sleeve or double offset ring spanner specification can reduce half.
Claims (3)
1, a kind of anti-skidding self-tightening sleeve, it comprises cylindrical shell (1), cylindrical shell (1) is provided with handle connector (2), be provided with sleeve cavity (5) in the cylindrical shell (1), it is characterized in that: the eccentric arc (8) that at least two symmetries are set in the described sleeve cavity (5), on eccentric arc (8), be provided with corresponding with it eccentric bolt die (6), the upper and lower end face of eccentric bolt die (6) is provided with arc groove (4), ring spring (3) is set in the arc groove (4), and the end opening of sleeve cavity (5) is provided with buckle (7) and blocks eccentric bolt die (6).
2, anti-skidding self-tightening sleeve according to claim 1 is characterized in that: described eccentric bolt die (6) is provided with teeth (9).
