The width of the front end of the stop blade is smaller than the width of the rear end of the stop blade, and the height of the front end of the stop blade is greater than the height of the rear end of the stop blade. This fiberboard nail has the characteristics of anti-loosening and reliable locking, with complete overall function and strong practicality.

Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and more specifically, to a fiberboard nail. Background Technology

[0002] Existing fiberboard nails, when connecting fiberboard, solid wood, and other materials, rely solely on the friction between the threads and the board for fixation. Over time, or under the influence of vibration and temperature changes, they are prone to loosening or even falling off. While some fiberboard nails are equipped with washers to enhance sealing, the washers only provide cushioning and cannot prevent the nail from rotating backwards, still failing to meet the requirements for a stable, long-term connection, resulting in overall unsatisfactory performance. Therefore, this utility model proposes a new type of fiberboard nail. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fiberboard nail that has the characteristics of being anti-loosening and securely locked.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a fiberboard nail, comprising a pan-head fiberboard nail body. The pan-head fiberboard nail body includes a nail head in the shape of a pan head, a shank with full threads, and a self-tapping tail with a sharp end. A soft rubber washer is fitted onto the shank and tightly adheres to the nail head. The soft rubber washer has several circumferentially extending stop holes, which also extend axially along the soft rubber washer and are connected to the outside at both ends. Each stop hole contains a stop blade connected to the nail head, and the stop blade has the same thread direction as the shank. The front end of the stop blade is a sharp end, and the rear end is a flat end. The width of the front end of the stop blade is smaller than the width of the rear end of the stop blade, and the height of the front end of the stop blade is greater than the height of the rear end of the stop blade.

[0005] The present invention is further configured such that the thickness of the soft rubber washer is greater than the maximum height of the stop blade.

[0006] The present invention is further configured such that: the included angle between two adjacent stop holes is equal; and the circumferential extension angle of each stop hole is equal.

[0007] The present invention is further configured such that the soft rubber gasket is made of rubber material.

[0008] The present invention is further configured such that the stop blade and the nail head are an integral structure.

[0009] In summary, this utility model has the following beneficial effects: 1. Through the cooperation of the soft rubber washer and the stop blade, the stop blade is screwed into the working surface to form a one-way stop structure, which effectively prevents the fiberboard nail from falling back and loosening, and significantly improves the connection stability and durability.

[0010] 2. The soft rubber gasket has both cushioning and sealing functions. The stop blade design does not affect the normal screwing of the nail body. The overall structure is simple, requires no additional processing steps, is suitable for existing installation scenarios, and is easy to use. Attached Figure Description

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1 See Figure 1 and Figure 2 As shown, the fiberboard nail involved in this embodiment includes a pan head fiberboard nail body. The pan head fiberboard nail body includes a nail head 1 with a pan head shape, a rod 2 with full threads, and a self-tapping tail (not shown) with a sharp end. A soft rubber washer 3 is fitted on the rod 2 and closely adheres to the nail head 1. The soft rubber washer 3 has several circumferentially extending stop holes 4. The stop holes 4 also extend axially along the soft rubber washer 3 and are connected to the outside at both ends. Each stop hole 4 is provided with a stop blade 5 connected to the nail head 1. The stop blade 5 has the same thread direction as the thread on the rod 2. The front end of the stop blade 5 is a sharp end and the rear end is a flat end. The width of the front end of the stop blade 5 is smaller than the width of the rear end of the stop blade, and the height of the front end of the stop blade 5 is greater than the height of the rear end of the stop blade.

[0015] Furthermore, the thickness of the soft rubber washer 3 is greater than the maximum height of the stop blade 5.

[0016] Furthermore, the included angle between two adjacent stop holes 4 is equal; the circumferential extension angle of each stop hole 4 is equal.

[0017] Furthermore, the soft rubber gasket 3 is made of rubber material.

[0018] Furthermore, the stop blade 5 and the nail head 1 are an integral structure.

[0019] In practice, first align the self-tapping end of the fiberboard nail with the fiberboard or solid wood surface to be connected, and then screw the nail in by turning the head of the nail with a tool. Initially, the soft rubber washer is in its natural state, and the locking edge is completely embedded in the locking holes around it, which does not affect the normal driving of the nail. As the screw is driven deeper, the nail head gradually presses against the working surface, and the soft rubber washer flattens under pressure, exposing the locking edge from the locking hole. As the screw is tightened further, the sharp tip of the locking edge breaks into the working surface as the nail rotates. Because the locking edge rotates in the same direction as the thread on the shank and its rear end is flat, when the nail tends to retreat, the flat end comes into contact with the working surface and cannot rotate in the opposite direction. At the same time, the flattened soft rubber washer cannot spring back, ultimately locking the fiberboard nail firmly in the construction position.

[0020] The fiberboard nail involved in this utility model, through the cooperation of a soft rubber washer and a stop blade, forms a one-way stop structure after the stop blade is screwed in, effectively preventing the fiberboard nail from backing back and loosening, and significantly improving the connection stability and durability; in addition, the soft rubber washer also has a buffering and sealing function, the stop blade design does not affect the normal screwing of the nail body, the overall structure is simple, no additional processing steps are required, it is suitable for existing installation scenarios, is convenient to use, has complete overall functions, and is highly practical.
