Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more particularly to an anti-deformation dry wall screw. Background Art

[0002] Drywall screws with a relatively large height and diameter are prone to deformation due to torque during installation. Therefore, it is necessary to strengthen the connection between the nail body and the nail head to prevent deformation during use. Accordingly, the present invention provides a drywall screw that prevents deformation. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide an anti-deformation drywall screw, which has the characteristics of strong anti-deformation ability and safe and reliable use.

[0004] To solve the above technical problems, the purpose of the present invention is achieved as follows: The present invention relates to an anti-deformation drywall screw, comprising a nail body and a nail head, wherein a polished rod portion having an outer diameter larger than that of the nail body is connected in series between the nail head and the nail body, and the polished rod portion and the nail body are arranged coaxially;

[0005] The polished rod portion is provided with a plurality of adjacent first reinforcement grooves with equal interval angles and extending in the axial direction. The first reinforcement grooves are arranged close to the nail head, and at least one second reinforcement groove extending along the circumference of the polished rod portion is provided between two adjacent first reinforcement grooves.

[0006] The polished rod portion is provided with a plurality of third reinforcing grooves with equal adjacent angles and extending axially. The third reinforcing grooves are arranged close to the nail body, and at least one fourth reinforcing groove extending along the circumference of the polished rod portion is provided between two adjacent third reinforcing grooves.

[0007] The present invention is further configured such that one end of any of the first reinforcement grooves facing the nail body extends between two adjacent third reinforcement grooves that match it.

[0008] The utility model is further configured as follows: an end of any of the third reinforcement grooves facing the nail head extends to between two adjacent first reinforcement grooves matched therewith.

[0009] The utility model is further configured as follows: a truncated cone-shaped transition portion is connected in series between the polished rod portion and the nail body, wherein the large end of the transition portion is connected to the polished rod portion, and the small end is connected to the nail body.

[0010] The utility model is further configured as follows: two second reinforcing grooves extending along the circumference of the polished rod portion are provided between two adjacent first reinforcing grooves; and two fourth reinforcing grooves extending along the circumference of the polished rod portion are provided between two adjacent third reinforcing grooves.

[0011] In summary, the present invention has the following beneficial effects:

[0012] 1. By connecting a polished rod portion with an outer diameter larger than the outer diameter of the nail body in series between the nail head and the nail body, the drywall nail still has better torsional resistance and deformation prevention when the height and diameter are relatively large.

[0013] 2. By arranging the staggered first and second reinforcing grooves and the staggered third and fourth reinforcing grooves on the polished rod part, the torsional resistance of the polished rod part is enhanced and deformation is prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See also Figure 1 and Figure 2 As shown, the anti-deformation drywall screw involved in this embodiment includes a nail body 1 and a nail head 2. A polished rod portion 3 with an outer diameter larger than that of the nail body is connected in series between the nail head 2 and the nail body 1. The polished rod portion 3 is coaxially arranged with the nail body 1.

[0020] The polished rod portion 3 is provided with a plurality of adjacent first reinforcement grooves 4 with equal angles and extending in the axial direction. The first reinforcement grooves 4 are arranged close to the nail head 2. Two second reinforcement grooves 5 extending along the circumference of the polished rod portion are provided between two adjacent first reinforcement grooves 4.

[0021] The polished rod portion 3 is provided with a plurality of third reinforcing grooves 6 with equal adjacent angles and extending axially. The third reinforcing grooves 6 are arranged close to the nail body 1. Two fourth reinforcing grooves 7 extending along the circumference of the polished rod portion are provided between two adjacent third reinforcing grooves 6.

[0022] Example 2

[0023] See also Figure 1 and Figure 2 As shown, the anti-deformation drywall screw involved in this embodiment is further configured on the basis of Example 1, so that the end of any first reinforcement groove 4 facing the nail body extends to between two adjacent third reinforcement grooves 6 matched therewith.

[0024] Furthermore, one end of any of the third reinforcement grooves 6 facing the nail head extends to between two adjacent first reinforcement grooves 4 that match it.

[0025] In this embodiment, by extending the end of any first reinforcement groove 4 facing the nail body to between the two adjacent third reinforcement grooves that match it, and extending the end of any third reinforcement groove 6 facing the nail head to between the two adjacent first reinforcement grooves 4 that match it, there is no anti-torsion blind area between the first reinforcement groove 4 and the third reinforcement groove 6, and the axially overlapping positions of the two can have a better anti-torsion effect.

[0026] Example 3

[0027] See also Figure 1 and Figure 2 As shown, the anti-deformation drywall screw involved in this embodiment is further configured as follows on the basis of Examples 1 and 2: a truncated cone-shaped transition portion 8 is connected in series between the polished rod portion 3 and the nail body 1, and the large end of the transition portion 8 is connected to the polished rod portion, and the small end is connected to the nail body.

[0028] In this embodiment, the provision of the transition portion 8 enhances the structural strength and torsional resistance of the connection.

[0029] The anti-deformation drywall screw involved in the utility model has a polished rod portion with an outer diameter larger than the outer diameter of the nail body connected in series between the nail head and the nail body, so that even when the height and diameter of the drywall screw are relatively large, it still has good torsional resistance and deformation prevention. In addition, by arranging staggered first and second reinforcing grooves and staggered third and fourth reinforcing grooves on the polished rod portion, the torsional resistance of the polished rod portion is enhanced, the deformation prevention is achieved, the overall function is complete, and the practicality is strong.
