Abstract

The utility model discloses a locking gasket which comprises a gasket body provided with an inner hole; and two planes of the gasket body are correspondingly provided with convex fins. The convex finsare uniformly arranged in spiral tooth shape. When being matched and used with other standard pieces, pits adaptive to the convex fins are correspondingly arranged on the pressing surface of connectors and nuts adjacent to the two planes of the gasket body; the convex fins on the two planes of the gasket body are pressed into the pits on the pressing surface stuck therewith with the gradual screwing of the nuts; after the whole connectors are pressed tightly, the gasket body becomes a 'spring jack gasket' therein; and the nuts are impossible to be dismounted without using a special tool. Thelocking gasket not only can guarantee firm connection when being used under higher vibration environment, but also can prevent the national base facilities (such as railways, bridges, high-voltage wire towers, and the like) from being stolen by thieves.

Description

The locking pad

Technical field

The utility model relates to and bolt, the matching used standard piece-pad of nut, especially relates to a kind of locking pad.

Background technique

After bolt, nut, spring pad, these standard piece combinations of flat gasket, be commonly used for the connection at detachable position.At some special occasions; when using down as the stronger environment of railway, bridge, high-tension line tower and some vibratilities; these links commonly used through regular meeting owing to become flexible and cause very serious consequence, abominable even can cause the person and the property loss that can't retrieve.

The model utility content

The purpose of this utility model is to provide a kind of locking pad that also can not make connection part loosening that uses in vibration environment.

For achieving the above object, the utility model can be taked following technical proposals:

Locking pad described in the utility model comprises the clout body that has endoporus, and correspondence is provided with the projection fin on two planes of described clout body.

The balanced setting of dentation in the shape of a spiral of described projection fin.

Advantage of the present utility model is that correspondence is provided with the projection fin on two planes of clout body, when being used with other standard piece, the corresponding pit that adapts with the projection fin that sets out on the link that will be adjacent and the pressing surface of nut with clout body two planes, projection fin on clout body two planes is along with nut tightens in the pit that is pressed on the pressing surface that fits with it gradually, after whole connection part compresses, clout body becomes " the very heavy pad of spring " therein, want nut is disassembled again, not using special tool is impossible substantially, not only under the stronger environment of vibration, use and to guarantee that it is connected firmly, prevented that also national Infrastructure is (as railway, bridge, high-tension line tower etc.) meet with pest's theft; In actual the use, what of projection fin can be according to required flexible flexible in size setting.With the balanced setting of dentation in the shape of a spiral of the projection fin on clout body two planes, not only the screw-in of convenient whole connection part compresses, and the locking effect is also better.The utility model is simple in structure, and is easily manufactured, and it is firm to connect effect, and spring pad and plain cushion are united two into one, and has saved raw material.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the right elevation of Fig. 1.

Embodiment

As shown in the figure, locking pad described in the utility model comprises the clout body 2 that has endoporus 1, the corresponding balanced projection fin 3 that is provided with of dentation in the shape of a spiral that is provided with on two planes of described clout body 2.During use, the corresponding pit that adapts with projection fin 3 that sets out on the link that will be adjacent and the pressing surface of nut with 2 liang of planes of clout body, the nut of screwing on after being through link and locking pad together with bolt, projection fin 3 on 2 liang of planes of clout body is along with nut tightens in the pit that is pressed on the pressing surface that fits with it gradually, after whole connection part compresses, clout body 2 becomes " the very heavy pad of spring " therein, want nut is disassembled again, not using special tool is impossible substantially.

Claims

1, a kind of locking pad comprises the clout body (2) that has endoporus (1), and it is characterized in that: correspondence is provided with projection fin (3) on two planes of described clout body (2).

2, locking pad according to claim 1 is characterized in that: described projection fin (3) the balanced setting of dentation in the shape of a spiral.
