Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

In a first embodiment, please refer to fig. 1-2, the present invention provides a technical solution: the utility model provides a high strength metal nut, includes nut body 1, and nut body 1's top fixed mounting has dome 2, and spout 3 has been seted up to nut body 1's inner wall, and sliding connection has between spout 3 extends lid 4, extends lid 4 through setting up, has played the supplementary effect that covers bolt one end.

Referring to fig. 1-3, a spring 5 is fixedly mounted on the inner wall of the nut body 1, a positioning bead 6 is fixedly connected to one end of the spring 5, a positioning hole 7 is formed in the surface of the extension cover 4, the positioning bead 6 and the positioning hole 7 are symmetrically distributed on two sides of the nut body 1 and the extension cover 4 respectively, the positioning beads 6 are symmetrically distributed to play a role in stably connecting the extension cover 4, the positioning beads 6 are distributed on the inner wall of the nut body 1 at equal intervals, and the extension cover 4 can be limited at different positions by arranging multiple groups of positioning beads 6.

In the second embodiment, referring to fig. 1, the surface of the nut body 1 is provided with the reinforcing device, the reinforcing device includes a reinforcing seat 8, the reinforcing seat 8 is disposed on the outer surface of the nut body 1, a rib 9 is fixedly connected between the reinforcing seat 8 and the nut body 1, the rib 9 is uniformly distributed on the reinforcing seat 8 and the nut body 1 in a circumferential state, and the reinforcing seat 8 and the nut body 1 are stably connected by the plurality of groups of ribs 9.

Referring to fig. 1, the rib 9 penetrates the interior of the reinforcing seat 8, and the surface of the reinforcing seat 8 is not smooth any more by penetrating the rib 9 through the reinforcing seat 8, which is convenient for people to rotate the reinforcing seat 8.

The working principle is as follows: through setting up nut body 1, the round cap 2, spout 3, extend lid 4, spring 5, location pearl 6 and locating hole 7, in the butt joint in-process of nut body 1 and bolt, when meetting the longer bolt of length, only need extend lid 4 stimulate downwards can, at this moment location pearl 6 receives external force influence then drives spring 5 and contracts backward, and then shift out along locating hole 7 inner wall, extend lid 4 also can slide between the spout 3 of nut body 1 inner wall, when extending lid 4 and moving to next location pearl 6 position department, spring 5 then drives location pearl 6 and resets this moment, make it run through to extending in the locating hole 7 of lid 4 one side, play spacing effect that extends lid 4 once more, thereby the length that extends lid 4 can obtain adjusting and bolt looks adaptation simultaneously, at last people only need with nut body 1 with bolt butt joint installation can, through setting up reinforcing apparatus, utilize the mode of installing reinforcement seat 8 around nut body 1, and then improved the intensity of nut body 1 self, strengthen seat 8 surface and be equipped with bead 9 simultaneously, thereby make things convenient for people to rotate nut body 1, avoid people to rotate the smooth in-process of nut body 1 surface the smooth circumstances to appear in the circumstances.
