The utility model discloses a following technical scheme realizes: prevent twisting off screw, be provided with screw rod and nut, screw rod and nut between adopt integrated into one piece structure the screw rod on be provided with the screw thread the nut on be provided with the interlock breach in be provided with protective part, protective part be the protection gum cover, the direct suit of protection gum cover at the surface of nut, protection gum cover and nut between be provided with positioning element.
The positioning component is a positioning pin rod, a round hole is formed in the nut, and the positioning pin rod is embedded into the round hole.
The locating pin rod is of a pointed pin rod structure, an external thread is arranged on the outer surface of the locating pin rod, an internal thread is arranged in a round hole formed in the nut, and the external thread is meshed with the internal thread in the round hole.
Compared with the prior art, the utility model discloses when making used, can utilize the outside protection gum cover that sets up of nut, can utilize the protection gum cover to carry out the protection of surface to the nut, increased the lifting surface area of nut simultaneously, can let the screw in the operation, can avoid concentrating the atress, cause the screw to break, can let the use safety more of screw.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an assembly drawing of the protective rubber sleeve of the utility model.
In the figure: 1 is a screw, 2 is a screw cap, 3 is an occlusion gap, 4 is a protective rubber sleeve, 5 is a protective rubber sleeve, 11 is a thread, 21 is a round hole, and 22 is a positioning pin rod.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
Prevent twisting off screw is provided with screw rod 1 and nut 2, screw rod 1 and nut 2 between adopt integrated into one piece structure screw rod 1 on be provided with screw thread 11 nut 2 on be provided with interlock breach 3 in be provided with the protective part, the protective part be protective rubber cover 4, the direct suit of protective rubber cover 4 at the surface of nut 2, protective rubber cover 4 and nut 2 between be provided with positioning element.
Be provided with protection gum cover 4 at the surface of nut 2, rely on locating component to fix a position and fix between protection gum cover 4 and the nut 2, can let the fine surface of fixing at nut 2 of protection gum cover 4 through locating component, setting up through protection gum cover 4 can let nut 2's lifting surface area grow, can let the screw lifting surface area grow in the rotation, can let the avoidance atress of screw too big, make the screw have the risk of twisting off, can satisfy the job requirements of the safe operation of screw.
Utilize locating component can be fine fix the surface at nut 2 with protection gum cover 4, the locating component is positioning pin pole 5, nut 2 on be provided with round hole 21 embedded positioning pin pole 22, positioning pin pole 22 be tip pin pole structure just positioning pin pole 22's surface be provided with the external screw thread nut 2 on be provided with the internal thread in the round hole 21 that sets up, positioning pin pole 5 go up the internal thread intermeshing in external screw thread and the round hole 21.
When the screw is transported, the screw can be sleeved with the protective rubber sleeve 5 in the transportation process for the abrasion of the outer surface of the screw, the protective rubber sleeve 5 is made of flexible rubber, the protective rubber sleeve 5 is internally provided with an inserting hole, the screw is inserted into the inserting hole, and the protective rubber sleeve 5 is utilized to play a role in protecting the outer surface of the screw.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
