Description

Technical Field

[0001] The utility model relates to the field of decoration, in particular to a cap-preventing dropping coil nail. Background Technique

[0002] In the existing workpiece assembly, in order to firmly connect two articles, coil nails or screws are usually used to connect them. Compared with screws, coil nails do not need to be pre-drilled. It is only necessary to use a tool to drive them into the connecting workpiece. Such coil nails are widely used by decoration workers during the decoration process of houses.

[0003] In order to drive the coil nails more quickly, several coil nails are usually arranged in a coil by a connecting wire (the connecting wire is usually a wire that can be freely bent), and then the coil nails are driven into the workpiece or wall for fixation according to the arrangement structure by a nail gun.

[0004] After the existing coil nails are driven into the workpiece, for aesthetic effects, the nail bodies of the coil nails are usually driven into the wall completely using tools such as hammers. This makes it difficult to use tools to pry them out when they need to be taken out (the force-bearing surface of the coil nail cap is usually a flat structure. In order to ensure that the coil nail cap will not fall off due to uneven force, the connecting end of the coil nail cap and the nail body is usually a conical surface structure). After the coil nails are driven into the wall or workpiece, the coil nail cap and the surface of the workpiece usually form a seamless structure. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that after the existing cap-preventing dropping coil nails are driven into the wall or workpiece, the coil nails are not easy to take out.

[0006] To solve the above technical problem, the technical solution provided by the utility model is: a cap-preventing dropping coil nail, including a coil nail row. The coil nail row includes a connecting wire and a plurality of coil nails located on one side of the connecting wire. One side of the coil nail cap at the top of the coil nail is provided with a T-shaped strengthening layer. A groove-shaped hole is provided on the top surface of the thick column end of the T-shaped strengthening layer. A wrench sandwich layer is provided on the side surface of the thick column end of the T-shaped strengthening layer. A shock-absorbing gasket is provided at the thin column end of the T-shaped strengthening layer.

[0007] As an improvement, spiral threads are provided on the nail surface of the coil nail.

[0008] As an improvement, a reinforcing pointed head is provided on the bottom surface of the coil nail.

[0009] As an improvement, the T-shaped strengthening layer is connected to the top flat end of the coil nail by welding.

[0010] As an improvement, the connecting wire is connected to the side wall of the nail surface of the coil nail by spot welding.

[0011] As an improvement, the top surface of the thick column end of the T-shaped strengthening layer is an arc surface.

[0012] The advantages of the present utility model compared with the prior art are as follows: On one side of the nail cap at the top of the coil nail, a T-shaped strengthening layer is welded by an electric welding machine, and a wrench sandwich layer is cut on the side wall of the T-shaped strengthening layer for the clamping of the wrench, so as to facilitate the removal of the coil nail. In order to prevent the welding end from breaking due to excessive force, a shock-absorbing gasket is sleeved on the thin column end of the T-shaped strengthening layer to reduce the force on the welding point. The card slot formed between the thin column end of the T-shaped strengthening layer and the nail cap can be used as the clamping point of the nail puller after the shock-absorbing gasket is removed.

[0018] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] As shown in the Figure 1 specification 2 drawing, it includes a coil nail row 1. The coil nail row 1 includes a connecting wire 11 and a plurality of coil nails 12 located on one side of the connecting wire 11. The connecting wire 11 is welded to the nail surface side wall of the coil nail 12 by spot welding, arranging each coil nail 12 in sequence, placing the connecting wire 11 on the nail body of the coil nail 12, and using a spot welding machine to weld the two (the function of spot welding is to ensure the normal connection of the two, and when the coil nail 12 is subjected to a large force, the connection between the two can be instantly disconnected), ensuring that when the coil nail row 1 drives out the coil nail 12, the coil nail 12 and the connecting wire 11 will not fail to be normally separated.

[0020] The nail surface of the coil nail 12 is provided with a threaded pattern 121, and the bottom surface of the coil nail 12 is provided with a reinforcing tip 122. The threaded pattern 121 can ensure that the nail body of the coil nail 12 can be more firmly connected after being driven into the workpiece and will not be easily loosened due to the smoothness of the nail body. The reinforcing tip 122 can concentrate the force application point so that the coil nail 12 can be driven into the workpiece more labor-saving.

[0021] As shown in the attached drawings of the specification Figure 2 , 3 , and Figure 4, on one side of the staple cap at the top of the staple 12, there is a T-shaped reinforcement layer 2. The top surface of the thick column end of the T-shaped reinforcement layer 2 is an arc surface. There is a groove-shaped hole 21 on the top surface of the thick column end of the T-shaped reinforcement layer 2. There is a wrench sandwich layer 22 on the side surface of the thick column end of the T-shaped reinforcement layer 2. There is a shock-absorbing gasket 23 at the thin column end of the T-shaped reinforcement layer 2. The T-shaped reinforcement layer 2 is connected to the top flat end of the staple 12 by welding. The top surface of the thick column end of the T-shaped reinforcement layer 2 is provided with an arc surface structure, which can prevent the stress point of the T-shaped reinforcement layer 2 from concentrating on the edge of the thick column end of the T-shaped reinforcement layer 2, so as to avoid the welding point between the thin column end of the T-shaped reinforcement layer 2 and the top surface of the staple 12 from breaking due to excessive stress deviation. Similarly, the function of the shock-absorbing gasket 23 is also to reduce the influence on the welding point between the thin column end of the T-shaped reinforcement layer 2 and the top surface of the staple 12 when the stress point of the thin column end of the T-shaped reinforcement layer 2 is not at the center; a groove-shaped hole 21 is opened on the top surface of the thick column end of the T-shaped reinforcement layer 2 to facilitate the removal of the staple 12. People can insert a screwdriver into the groove-shaped hole 21 and reverse it through the spiral thread 121 on the body of the staple 12 to take out the staple. Similarly, the wrench sandwich layer 22 is to provide a clamping point for the movable wrench to cooperate with the spiral thread 121 on the body of the staple 12; when the groove-shaped hole 21 and the wrench sandwich layer 22 fail due to long-term use, the shock-absorbing gasket 23 can be removed, and a nail puller is used to engage with the thin column end of the T-shaped reinforcement layer 2 to facilitate the removal of the staple 12.

[0022] When the present utility model is specifically implemented, the staple row 1 is installed in a stapler. The stapler is used to drive the staple 12 into the connection part of the workpiece or the wall. Finally, a hammer is used to completely drive the staple 12 into the wall to prevent the exposed part from hurting people; when it needs to be taken out, a screwdriver can be inserted into the groove-shaped hole 21 or a movable wrench can be used to clamp the wrench sandwich layer 22, and the wrench or the screwdriver is reversed to take out the staple 12 through the spiral thread 121 on the surface of the staple 12; the shock-absorbing gasket 23 can also be removed, and a nail puller is inserted into the card slot formed between the thin column end of the T-shaped reinforcement layer 2 and the staple cap, and the staple 12 is taken out by rotating the nail puller.

[0023] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present utility model.
