Description

Locknut sleeve for wood connection

Technical Field

The utility model relates to a nut fastening accessory, in particular to a locknut sleeve for wood connection.

Background

Bolts are called in a number, each may be different, and are called screws, bolts, fasteners, although the meaning is the same, bolts are common references to fasteners, and bolts are means for progressively fastening a work of a device using the physical and mathematical principles of the bevel circular rotation and friction of an object.

In common wood connection and wooden furniture, the body and the shadow of a bolt fastener are also visible everywhere, but the bolts used in the conventional wood connection and wooden furniture are mostly common connecting bolts, so that the locking function is not achieved, the locking effect is poor, the stability is low, and the stability of connection cannot be ensured for a long time; in daily use and handling, the phenomenon that bolted connection is not hard up appears easily, destroys its structural integrity, influences timber connecting piece and wooden furniture's life and result of use.

Disclosure of Invention

In order to achieve the above problems, an object of the present utility model is to provide a locknut cover for wood connection, which can be used in conjunction with nuts and bolts to strengthen the connection of wood, and also greatly enhance its locking performance.

In order to achieve the above object, the present utility model adopts the following scheme:

the utility model provides a locknut cover that timber was connected usefulness, its includes nut cover body and hook tooth, nut cover body is used for placing the nut, and its lower extreme is equipped with the opening, and its upper end is equipped with the hook tooth and supplies the opening that the screw rod passed through, the projection of hook tooth is right triangle, and its right angle limit is located and is close to nut cover one side, the hook tooth is equipped with bilateral symmetry's two, the hook tooth side of two hook teeth keeps parallelism.

Preferably, the number of the hook teeth is four, and the hook teeth on opposite angles of the hook teeth are symmetrically arranged in pairs.

Preferably, the nut is an outer hexagonal nut.

Preferably, the upper end of the nut sleeve body is provided with a snap ring portion which cooperates with the threads.

Preferably, each edge of the nut sleeve body is rounded.

In summary, the utility model has the advantages that the hook teeth are arranged, and can be firmly clamped into the wood when the wood is connected, so that the loosening caused by vibration is prevented.
