Abstract

The utility model discloses a screw capable of preventing twisting, which comprises a head part and a rod part, wherein a groove is formed in the head part, a plurality of springs are arranged in the groove along the edge of the groove, a pressing plate is connected to the springs, and a gap exists between the edge of the pressing plate and the inner wall of the groove. The groove, the spring and the pressing plate provided by the utility model can prevent a tool from being inserted into the head of the screw in an incorrect pressing-in direction, and the existence of the spring can provide stable reaction force to ensure that the pressing plate keeps unbalanced in the incorrect pressing-in direction, so that the tool cannot be inserted into the groove, thereby preventing the screw from being twisted; the improved anti-skid patterns prevent the tool from slipping when the pressing plate is pressed into the groove, and normal screw screwing operation is not affected.

Description

Screw capable of preventing twisting

Technical Field

The utility model relates to a screw capable of preventing twisting.

Background

Screws are a common type of mechanical connection element, typically made of metal, with a threaded structure. It is mainly used for fixing two or more parts together and for fastening and unfastening by rotating screws.

However, in actual use, the screw is susceptible to twisting due to the influence of twisting force when the applied force is uneven or the applied angle is incorrect. Tightening of the skewed screws may result in a loose connection, reducing the reliability and stability of the connection, and may result in loosening or falling of the connection.

Disclosure of utility model

The present utility model is directed to a screw capable of preventing a screw from being twisted, and solves the problems of the prior art.

The aim of the utility model can be achieved by adopting the following technical scheme:

The utility model provides a prevent twisting askew screw, includes head and pole portion, be provided with the recess on the head, the inside a plurality of springs that are provided with along its edge of recess, be connected with the clamp plate on the spring, there is the clearance between the edge of clamp plate and the inner wall of recess.

Preferably, the shape of the groove is cross-shaped.

Preferably, the springs are disposed at four corners of the cross-shaped groove, respectively.

Preferably, the pressing plate is in a cross-shaped structure.

Preferably, a portion of the platen is disposed inside the recess and another portion of the platen is disposed outside the recess.

Preferably, a positioning hole is formed in the middle of the pressing plate.

Preferably, the positioning hole is in a truncated cone-shaped structure with a large upper part and a small lower part.

Preferably, the pressing plate is provided with anti-skid patterns.

The beneficial technical effects of the utility model are as follows:

The groove, the spring and the pressing plate provided by the utility model can prevent a tool from being inserted into the head of the screw in an incorrect pressing-in direction, and the existence of the spring can provide stable reaction force to ensure that the pressing plate keeps unbalanced in the incorrect pressing-in direction, so that the tool cannot be inserted into the groove, thereby preventing the screw from being twisted; the improved anti-skid patterns prevent the tool from slipping when the pressing plate is pressed into the groove, and normal screw screwing operation is not affected.

Detailed Description

In order to make the technical solution of the present utility model more clear and obvious to those skilled in the art, the present utility model will be described in further detail with reference to examples and drawings, but the embodiments of the present utility model are not limited thereto.

As shown in fig. 1-4, the anti-twisting screw provided in this embodiment includes a head 1 and a rod 2, a groove 3 is provided on the head 1, a plurality of springs 4 are provided along the edges of the groove 3, a pressing plate 5 is connected to the springs 4, a gap exists between the edges of the pressing plate 5 and the inner wall of the groove 3, so that a tool can be prevented from being inserted into the head 1 of the screw in an incorrect pressing direction, if the pressing direction of the tool is incorrect, the applied force can make the pressing plate 5 high on one side and low on the other side, and the tool is ejected out of the groove 3 by the high side of the pressing plate 5, so that the tool cannot twist the screw, and the screw is prevented from being twisted.

In this embodiment, as shown in fig. 2 and 3, the shape of the groove 3 is cross-shaped, the springs 4 are respectively disposed at four corners of the cross-shaped groove 3, the pressing plate 5 is in a cross-shaped structure, and each of the four directions is provided with one spring 4, so that when the tool is pressed in an incorrect direction, the correct direction can be quickly adjusted according to the raising direction of the pressing plate 5, and the screw can be continuously screwed.

In this embodiment, as shown in fig. 4, a part of the pressing plate 5 is disposed inside the groove 3, so that the pressing plate 5 can be accurately pressed into the groove 3 at the initial stage of pressing in the tool, so that the screwing operation of the screw can be smoothly performed, and the other part of the pressing plate 5 is disposed outside the groove 3, so that the pressing plate 5 can better eject the tool when the pressing direction of the tool is incorrect.

In this embodiment, as shown in fig. 3, a positioning hole 6 is provided in the middle of the pressing plate 5, and the positioning hole 6 has a truncated cone-shaped structure with a large top and a small bottom, so that the tool can find the correct insertion position more quickly.

In this embodiment, as shown in fig. 1, the pressing plate (5) is provided with anti-skidding patterns, so that the tool will not slip when pressing the pressing plate 5 into the groove 3, and normal screwing operation will not be affected.

In summary, in the present embodiment, the groove 3, the spring 4 and the pressing plate 5 provided in the present embodiment can prevent the tool from being inserted into the screw head 1 in an incorrect pressing direction, and the presence of the spring 4 can provide a stable reaction force, so as to ensure that the pressing plate 5 is unbalanced in the incorrect pressing direction, and the tool cannot be inserted into the groove 3, thereby preventing the screw from being twisted; the provided anti-skid patterns prevent the tool from slipping when the pressing plate 5 is pressed into the groove 3, and normal screw screwing operation is not affected.

The above description is merely a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto, and any person skilled in the art will be able to apply equivalents and modifications according to the technical solution and the concept of the present utility model within the scope of the present utility model disclosed in the present utility model.
