Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a bolt. Referring to fig. 1, the screw cap 2 having a hexagonal shape and a screw 1 integrally formed with the screw cap 2 are included. The surface of the screw cap 2 is provided with an anti-rust layer which is red lead anti-rust paint. The nut 2 is exposed outside for a long time, so the rust-proof layer can slow down the corrosion of the nut 2 and prolong the service life of the nut 2.

Referring to fig. 2, a support ring 5 is integrally formed at the edge of one side of the nut 2 close to the screw 1 along the circumferential direction, and after the bolt is screwed, the support ring 5 can increase the contact area between the nut 2 and the surface of the object, thereby preventing the nut 2 from being excessively screwed to crush the surface of the object.

Referring to fig. 2, the connecting groove 21 that is the rectangle is seted up along self thickness direction in the middle part of one side that support ring 5 was kept away from to nut 2, and nut 2 has turning block 3 in connecting groove 21 sliding connection, and the lateral wall of turning block 3 all laminates with the inside wall of connecting groove 21. A connecting shaft 22 is fixedly connected between one ends, far away from the screw rod 1, of the inner side walls of the short sides of the two sides of the connecting groove 21, and a long hole 31 for the connecting shaft 22 to penetrate through is formed in the side wall of the short side of the rotating block 3 along the length direction of the rotating block 3. When the bolt needs to be rotated, the rotating block 3 is pulled out from the connecting groove 21, the rotating block 3 can provide an acting point for fingers, then the two sides of the rotating block 3 are pinched by hands and rotated, and the bolt can be screwed out without an additional tool.

Referring to fig. 2 and 3, the two opposite inner walls of the elongated hole 31 are fixedly connected with the reinforcing strips 34 along the length direction of the rotating block 3, and the two opposite side walls on the connecting shaft 22 are provided with sliding grooves 221 for the reinforcing strips 34 to be clamped in. The reinforcing bar 34 can increase the structural strength of the turning block 3 and prolong the service life of the turning block 3.

Referring to fig. 2, fig. 3, one side fixedly connected with that screw rod 1 was kept away from to turning block 3 is parallel with connecting axle 22 and is the fixed strip 32 of rectangle, the middle part of one side that support ring 5 was kept away from to nut 2 is seted up and is supplied the groove 23 of stepping down that the fixed strip 32 card was gone into, fixed strip 32 is connected with the fixed column 33 parallel with turning block 3 towards one side of stepping down groove 23 perpendicularly, the edge that fixed column 33 kept away from the one end of fixed strip 32 is provided with chamfer 331, the diapire of stepping down the groove 23 is seted up and is supplied fixed slot 24 that fixed column 33 card was gone into, fixed column 33 and fixed slot 24 interference fit. When the fixing post 33 is inserted into the fixing groove 24, the fixing post 33 is in interference fit with the fixing groove 24, so that friction exists between the outer side wall of the fixing post 33 and the inner side wall of the fixing groove 24, and the fixing post 33 is prevented from accidentally disengaging from the fixing groove 24, and the rotating block 3 is prevented from accidentally sliding out of the connecting groove 21.

Referring to fig. 2, the inner side wall of the yielding groove 23 around is fixedly connected with a rubber pad 4, and one side of the rubber pad 4 departing from the inner side wall of the yielding groove 23 tightly supports against the outer side wall of the fixing strip 32. The rubber pad 4 can fill the gap between the fixing strip 32 and the receding groove 23, so that dust is prevented from entering the connecting groove 21, and the rotating block 3 can be smoothly pulled out of the connecting groove 21.

Referring to fig. 2, semicircular pull-out grooves 25 are formed in both sides of the abdicating groove 23 on one side of the nut 2 away from the support ring 5, and the pull-out grooves 25 are communicated with the abdicating groove 23. The rotating block 3 can be pulled out from the connecting groove 21 by extending fingers into the pulling-out groove 25 and pinching the fixing strip 32.

The implementation principle of a bolt of the embodiment of the application is as follows: when the bolt needs to be rotated, fingers stretch into the pull-out grooves 25, the two opposite side walls of the fixing strips 32 are pinched, the rotating block 3 is pulled out of the connecting grooves 21, then the rotating block 3 is pinched by hands and rotated, the rotating block 3 can be made to drive the bolt to rotate, and therefore the bolt can be screwed out without the help of tools.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
