Abstract
The utility model relates to a stop screw which comprises a screw body and a screw tail. The head portion of the screw body is provided with a plurality of anti-looseness reverse teeth. One end of the screw tail is provided with an inner hexagonal hole, and the other end of the screw tail is provided with a plurality of anti-skidding teeth, and the anti-skidding teeth are arranged in an annular shape. According to the technical scheme of the stop screw, due to the fact that the anti-looseness reverse teeth are arranged on the head portion of the screw, the screw does not easily drop in the processes of fixation and connection; and due to the two methods, the anti-looseness function of the stop screw is achieved, and the screw can be firm, durable and safe in the process of utilization.
Description
Technical field
The utility model relates to a kind of screw, concrete relates to a kind of backing-up screw.
Background technique
Screw is as a kind of use five metals miscellaneous goods widely; Advantage with convenient and fast connection plays the effect that connects securing part in the ordinary course of things, in connecting fixation procedure; Phenomenons such as becoming flexible, come off appears in screw sometimes, thus some unnecessary troubles caused.
The model utility content
The utility model purpose is for the deficiency that overcomes existing technology a kind of backing-up screw to be provided.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of backing-up screw, comprise screw body, screw tail, and said screw body head is provided with a plurality of anticreep pawls; An end offers inner hexagonal hole on the said screw tail, and the other end is provided with a plurality of slideproof tooth; Said slideproof tooth circular array.
Preferably, the number of said anticreep pawl is 6～12.
Preferably, the number of said slideproof tooth is 24～36.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of backing-up screw of the utility model scheme; Through designing the anticreep pawl at screw head; Make screw difficult drop-off in being fixedly connected using process,, make screw in being fixedly connected using process, not be prone to slip through on the screw tail, designing slideproof tooth; Realized the backing-up screw of screw making the in use firm more durable safety of screw through these two kinds of means.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of backing-up screw of the utility model;
Wherein: 1, screw body; 2, screw tail; 3, anticreep pawl; 4, inner hexagonal hole; 5, slideproof tooth.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1 is the described a kind of backing-up screw of the utility model, comprises screw body 1, screw tail 2, and said screw body 1 head is provided with a plurality of anticreep pawls 3; An end offers inner hexagonal hole 4 on the said screw tail 2, and the other end is provided with a plurality of slideproof tooth 5; Said slideproof tooth 5 circular array; The number of said anticreep pawl 3 is 6; The number of said slideproof tooth 5 is 36; The utility model scheme is through designing anticreep pawl 3 at screw head; Make screw difficult drop-off in being fixedly connected using process; Through design slideproof tooth 5 on screw tail 2; Make screw in being fixedly connected using process, not be prone to slip, realized the backing-up screw of screw making the in use firm more durable safety of screw through these two kinds of means.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
