Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Example 1

Referring to fig. 1 to 6, in this embodiment, a locking bolt is provided, which includes a nut 1, a washer 2, a ground bolt 3, a pin 4, and a screw 5, where the nut 1, the washer 2, the ground bolt 3, the pin 4, and the screw 5 form a locking structure, a pin slot 101 is formed in an inner side of the nut 1, a slot 102 is connected to a bottom of the pin slot 101, the slot 102 is formed in a bottom wall of the nut 1, an inner slot 201 is formed in an inner side wall of the washer 2, a plurality of diagonal teeth 202 are formed in an outer side wall of the washer 2, the diagonal teeth 202 are eight in total and are arranged annularly, a lateral diagonal tooth in a stretching direction inclines inward by no less than 45 degrees, the pin 4 is solid, a pin slot 501 is formed in a side wall of the screw 5, and the ground bolt 3 is semi-cylindrical and is bent by 90 degrees.

The anti-loose bolt directly limits the loosening of the nut 1 by utilizing the fixing principle of embedding the nut 1 and the screw 5 (namely, a bull-stumble drill type), thereby achieving the anti-loose effect;

the screw 5 is provided with a layer of gasket 2, the gasket 2 is thicker than a normal gasket (convenient for tooth pulling), an inner diagonal tooth 202 is arranged on the outer edge of the gasket 2 and is consistent with the dismounting direction of the nut 1, an inner groove 201 is arranged in the gasket 2, the screw 5 is provided with a vertical pin clamping groove 501 in a set range, a detachable pin 4 is arranged in the vertical pin clamping groove 501 opposite to the gasket 2 and the screw 5 and can slide up and down in the set range, the distance is convenient to adjust, and when the pin 4 is embedded, the gasket 2 and the screw 5 can only transversely move in the same direction and can be considered as a whole;

the lower end of the nut 1, which is in contact with the washer 2, is provided with a pin groove 101 in the direction opposite to the screw of the screw 5, one fifth of the lower part of the nut 1 is provided with a line groove 102 which is communicated and connected with the pin groove 101 at the lower end, (the size of the groove is determined by the size of the bolt type), and the ground bolt line 3 is made of a material; small iron wire and large steel bar: semi-cylindrical.

During installation, the washer 2 is sleeved in the screw rod 5, the pin 4 is placed, when the nut 1 is screwed down to one fifth away from the washer 2, the geodesic wire 3 which is bent by 90 degrees is placed in the pin groove 101 and the lower part wire groove 102 in the preset nut 1, and is screwed down again until the place is in place, then the geodesic wire 3 which extends out is in the closest position to the inclined pull tooth 202 of the washer 2 of the nut 1, the geodesic wire 3 is left with a good length and is bent to be embedded into the inclined pull tooth 202, so that the nut 1 is bolted, and looseness is avoided to achieve the anti-loosening effect.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art and related fields without creative efforts shall fall within the protection scope of the present invention. Structures, devices and methods of operation not specifically described or illustrated in the present application are not specifically illustrated or described, but are generally practiced in the art without limitation.
