Detailed Description
In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.
As shown in fig. 1-3, the hexagonal bolt with the anti-slip threads comprises a nut 10 and a screw 11, wherein the nut 10 is arranged in a hexagonal shape, an external thread is arranged on one side of the screw 11 far away from the nut 10, a working cavity 14 is formed in the nut 10, the screw 11 extends into the working cavity 14, the working cavity 14 is arranged in a square shape, a main pressing plate 17 is fixedly connected to the end surface of one side of the screw 11 close to the nut 10, an auxiliary pressing plate 15 is arranged on one side of the main pressing plate 17 far away from the screw 11, the auxiliary pressing plate 15 is arranged in the working cavity 14, the auxiliary pressing plate 15 and the main pressing plate 17 are also arranged in a square shape, and a spring 16 is fixedly connected between the end surface of one side of the auxiliary pressing plate 15 close to the screw 11 and the end surface of one side of the main pressing plate 17 far away from the screw 11;
at least two chutes are further formed in one side end face, close to the screw rod 11, of the screw cap 10, each chute is communicated with the working cavity 14, a sliding rod 13 is further arranged in each chute, at least two penetrating limiting holes 18 are formed in the main pressing plate 17, the limiting holes 18 correspond to the sliding rods 13, the sliding rods 13 extend and penetrate the limiting holes 18 in the direction close to the screw cap 10, one side end face, far away from the screw cap 10, of the sliding rod 13 is fixedly connected with a sealing gasket 12, the sealing gasket 12 can be made of rubber, the sealing performance of the bolt can be increased through the sealing gasket 12, the screw rod 11 is isolated from the outside, the screw rod 11 is prevented from being corroded by outside air, and the screw rod 11 is led to generate sliding threads when being installed.
When the bolt is used, the nut 10 is rotated by using a tool, under the limitation of the working cavity 14, the main pressure plate 17 drives the screw rod 11 to rotate, the bolt can be installed, when the connecting piece abuts against the sealing gasket 12, the sealing gasket 12 can be driven to move towards the direction close to the nut 10, so that the sliding rod 13 abuts against the auxiliary pressure plate 15, the auxiliary pressure plate 15 can be driven to overcome the elasticity of the spring 16 to move towards the direction far away from the screw rod 11, at the moment, under the elastic action of the spring 16, a certain pre-tightening force can be caused on the bolt in advance, on one hand, the screw rod 11 can be prevented from shaking, the stability of the bolt is improved, on the other hand, the required force during screwing can be increased, the stress size of the thread of the bolt is reduced under the same force, the phenomenon of thread slipping is avoided, when the sealing gasket 12 abuts against the nut 10, the screw rod 11 downwards passes through the main pressure plate 17, the sealing gasket 10 is made to extrude the sealing gasket 12, the sealing performance of the bolt is improved, the screw rod 11 is isolated from the outside, the corrosion of the screw rod 11 by outside is avoided, the external air, the thread slipping is caused, and the stability of the bolt can be further improved when the installation.
