Abstract
The utility model provides a screw is taken off in the antiskid, includes screw cap and nail physically, the center of screw cap is equipped with cross recess or straight line groove, and nail body one end is connected with the screw cap, be equipped with three cylinder groove on the screw cap, cylinder trench in cross recess or straight line groove's the groove footpath outside, and evenly distributed is 120 contained angles in screw cap upper surface, cylinder groove each other. A life that the screw is taken off in the antiskid, and the screw cap up end of cross recess or straight line groove screw is equipped with three cylinder groove, and cross recess or straight line groove insert the cylinder inslot through special instrument and screw up or dismantle behind a lot of dismouting wear out failure, have prolonged the practical life of screw greatly, and utilize two cylinder grooves or three cylinder groove all can realize screwing up or dismantling of screw, have further improved the screw.
Description
Technical field
This utility model relates to a kind of peg, particularly relates to a kind of anti-slip screw.
Background technology
At present, the domestic screw commonly used is standard component, is word screw or a plus screw.This screw tightness is good, easy accessibility.But due to coordinate with screwdriver the flat recess tightened or cross recess the most simple be molded on the end face of screw head, one word screw or plus screw are after repeatedly dismounting, often it is worn at flat recess or cross recess cell wall, insert flat recess or cross recessed screwdriver head is somewhat exerted oneself, i.e. skid off in groove, tightening and dismantling of screw cannot be realized, the service life causing screw is the longest, it is in the screw under adverse circumstances additionally for some use conditions, screw often corrosion, flat recess or cross recess are more susceptible to the abrasion of screwdriver, causing cannot knockout screw, affect the normal service of equipment.
Utility model content
The deficiency that this utility model exists for prior art just, it is provided that a kind of anti-slip screw.
For solving the problems referred to above, technical solution adopted in the utility model is as follows:
A kind of anti-slip screw, including screw cap and rivet nut, the center of described screw cap is provided with cross recess, rivet nut one end is connected with screw cap, described screw cap is provided with three cylinder grooves, cylinder groove is positioned at outside cross recessed groove footpath, and is evenly distributed on screw cap upper surface, and cylinder groove is each other in 120 ° of angles.
Further, the depth ratio cross recessed depth location of described cylinder groove is low and less than the thickness of screw cap.
Further, the inwall of described cross recess and cylinder groove is provided with wearing layer.
Compared with prior art, implementation result of the present utility model is as follows for this utility model:
The anti-slip screw of one described in the utility model, the screw cap upper surface of cross recess or slotted head screw is provided with three cylinder grooves, cross recess or flat recess are after being dismounted for multiple times wear out failure, tighten or dismantle in inserting cylinder groove by special instrument, substantially prolongs the physical life of screw, and utilize two cylinder grooves or three cylinder grooves all can realize tightening or dismantling of screw, further increase the service life of screw.
Accompanying drawing explanation
Fig. 1 is one described in the utility model anti-slip bolt structure schematic diagram；
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Detailed description of the invention
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1 with shown in Fig. 2, the anti-slip screw of described one includes screw cap 1 and rivet nut 2, the center of described screw cap 1 is provided with cross recess 3, rivet nut 2 one end is connected with screw cap 1, described screw cap 1 is provided with three cylinder grooves 4, cylinder groove 4 is positioned at outside the groove footpath of cross recess 3, and is evenly distributed on screw cap 1 upper surface, and cylinder groove 4 is each other in 120 ° of angles.
Screw cap 1 upper surface of cross recess 3 screw is provided with three cylinder grooves 4, cross recess 3 is after being dismounted for multiple times wear out failure, tighten or dismantle in inserting cylinder groove 4 by special instrument, substantially prolongs the physical life of screw, and utilize two cylinder grooves 4 or three cylinder grooves 4 all can realize tightening or dismantling of screw, further increase the service life of screw.
The depth location of the depth ratio cross recess 3 of described cylinder groove 4 is low and less than the thickness of screw cap 1, it is ensured that the practical intensity of screw cap 1, it is to avoid in rundown process, and screw cap 1 deforms, and affects service life.
The inwall of described cross recess 3 and cylinder groove 4 is provided with wearing layer 5, enhances the abrasion resistance of screw cross recess 3, further increases the service life of screw.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
