Description

Rivet nut rises with protective structure

Technical Field

The utility model relates to the field of nuts, in particular to a rivet expansion nut with a protection structure.

Background

The nut is a part which is screwed together with the bolt or the screw rod to play a role in fastening, and the nut and the bolt with the same specification can be connected together through the inner threads. At present, in mechanical design, the nut connection is a very common method, and has the advantages of simplicity, convenience, strong popularity and the like, but after two connecting pieces are connected together through the nut, the nut is easy to loosen due to vibration or external force in the use process, so that the nut is disconnected, and the nut connection is invalid.

In the prior art, a screw hole is usually formed in the side face of a nut, after the nut is screwed, a fixing column and other structures which can be fixed are inserted into the screw hole of the nut to achieve a fixing effect, but in the practical use process, due to the fact that the screw hole is formed, and the other structures such as the fixing column are needed to be fixed, the fixing column is quite troublesome in diameter, the fixing column is small in diameter, the fixing column is easy to break due to long-term stress, the nut is still easy to loosen and rotate after breakage, and due to rotation of the nut, the nut is loosened, so that the anti-loosening capacity of the nut is poor.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the rivet expansion nut with the protection structure, which can effectively solve the technical problem of poor locking capability of the existing nut.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a rivet nut rises with protective structure, includes cylinder, protection piece and connecting block, cylinder and connecting block integration set up, the protection piece encircle set up in the side of cylinder, a plurality of U-shaped grooves have been seted up to the connecting block, the inboard of connecting block and cylinder is provided with a plurality of screw threads, the round hole has been seted up to the bottom of protection piece.

Further, the outer surface of the column body is a smooth surface.

Further, the column, the protection block and the connection block are all made of stainless steel materials.

Further, the cylinder is circular.

Compared with the prior art, the utility model has the beneficial effects that: the expansion riveting nut with the protection structure has strong anti-loosening capability, plays a role in preventing loosening by arranging the U-shaped groove, enhances the connection tightness between the nut and the connected piece, directly screws and presses the nut when in use, enables the U-shaped groove and the connected piece to be clamped, and can realize the fixing effect.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, rivet nut rises with protective structure, including cylinder 1, protection piece 2 and connecting block 3, cylinder 1 and connecting block 3 integration set up, protection piece 2 encircle set up in the side of cylinder 1, a plurality of U-shaped grooves 5 have been seted up to connecting block 3, the inboard of connecting block 3 and cylinder 1 is provided with a plurality of screw threads 6, round hole 4 has been seted up to the bottom of protection piece 2, the surface of cylinder 1 is the smooth surface, cylinder 1, protection piece 2 and connecting block 3 constitute by stainless steel material, cylinder 1 is circular form.

The rivet nut that rises with protective structure of this embodiment is when using, directly screws the nut and presses, makes U-shaped groove 5 and by the connecting piece carry out the block and can realize the fixed action, after the nut is fixed, inserts structures such as cylinder in addition and realizes spacing function in round hole 4, further strengthens the locking ability of nut, avoids the nut to rotate and produces not hard up.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Claims (4)
