[0002] A washer refers to a part placed between the connected parts and the screw (bolt) nut, generally a flat metal ring, which is used to protect the surface of the connected parts from being scratched by the nut and to reduce the pressure / impact force during fixation.
[0003] With the development of nail shooting technology, a combined structure of fixing a washer to a nail has also been proposed in the prior art. For example, the patent document with the publication number CN105927649A discloses a nail bolt, which adopts a structure of fixing a buffer washer on the nail body, being convenient for construction and capable of playing a role of buffering and shock absorption during fastening. The buffer washer represented by this patent document is usually of a flat plate structure. However, through careful analysis, it is found that this flat plate structure washer is not suitable for fastening wood products (including fixing wood products to a substrate using a nail or fixing a nail to a wood product), because when using a nail to fix, due to the action of the shooting force, the nail tip will cause the wood product (especially a wooden strip) to crack when entering the wood product, thereby resulting in construction failure.
[0004] Therefore, it is necessary to improve the existing washer so that it can prevent the wood product from cracking when used for fastening wood products. Summary of the Utility Model

[0029] The fastening washer described in the present utility model and the fastener using the fastening washer have been successfully developed and trial-produced, and the applicant has tried using them and can effectively prevent the cracking of wood products. In order to better protect this technology, the applicant has applied for a utility model patent for this technology. The following will describe the present utility model in detail with reference to specific embodiments.
[0030] Embodiment 1
[0031] As Figure 1-5 shown, a fastening washer includes a washer body 1, and the washer body 1 is usually made of hard metal materials such as iron, copper, and stainless steel. According to Figure 1 the shown direction, the middle part of the washer body 1 bulges upward to form a buffer boss 2, and a nail hole 3 is opened in the middle of the buffer boss 2. The washer body 1 can be assembled on the nail 5 through the nail hole 3. In addition, downward sharp corners 4 are provided around the washer body 1. When used for fastening wood products, the sharp corners 4 will enter the wood products and grip the wood products, thereby preventing the wood products from cracking when the nail 5 enters. It should be noted that the periphery of the aforementioned washer body 1 only refers to the circumferential position of the washer body, and does not specifically refer to the four directions of the washer body 1.
[0032] When using the nail 5 to fasten wood products, the nail 5 is perpendicular to the wood products. Therefore, in this embodiment, it is preferred that the sharp corners 4 are perpendicular to the washer body 1, so that the sharp corners 4 can stably and reliably enter the wood products during fastening, thereby improving the gripping effect of the sharp corners 4 on the wood products. Of course, on the premise of not affecting the gripping effect or having a small impact on the gripping effect, the sharp corners 4 can also be slightly inclined in the vertical direction.
[0033] The washer body 1 in this embodiment mainly has the following two structures:
[0034] First, the washer body 1 has a circular structure, and when the washer body 1 has a circular structure, the sharp corners 4 are integrally formed around the washer body 1.
[0035] Second, the washer body 1 has a polygonal structure. When the washer body 1 has a polygonal structure, the sharp corners 4 are formed by bending all / part of the edges and corners of the washer body 1. It should be noted that when the washer body 1 has a polygonal structure, it can generally be a triangular structure, a quadrilateral structure, a pentagonal structure, a hexagonal structure, etc., and the sharp corners 4 can be formed by bending all / part of the edges and corners. For example, when the washer body 1 is a triangular structure, the sharp corners 4 can be formed by bending the three edges and corners of the washer body 1. When the washer body 1 is a quadrilateral structure, the sharp corners 4 can be formed by bending the four edges and corners or two diagonal edges and corners of the washer body 1. When the washer body 1 is a hexagonal structure, the sharp corners 4 can be formed by bending three spaced edges and corners of the washer body 1.
[0036] Furthermore, the number of the above-mentioned sharp corners 4 is 2 - 6, specifically it can be 2, 3, 4, 6, etc. However, to ensure a better grasping effect, it is preferred that the number of the sharp corners 4 is 4. In this way, a better grasping force can be generated on the wooden product from all around, thereby effectively preventing the wooden product from cracking.
[0037] It should be noted that the overall shape of the sharp corner 4 in this embodiment is generally a triangular structure so as to be able to effectively enter the wooden product. The length ( Figure 1 the height shown) of the sharp corner 4 is preferably such that it can effectively grasp the wooden product.
[0038] This embodiment is particularly suitable for the fastening of wooden products, but can also be applied to the fastening of plastic products. As Figure 7 shown, when this embodiment is in use, it is mainly assembled on the nail 5 through the nail hole 3 and fired by a nail gun. Taking the example of fastening a nail 5 on a wooden strip, during fastening, the buffer boss 2 on the washer body 1 will reduce the impact force during fixation. Under the action of the shooting force, the sharp corners 4 on the washer body 1 will enter the wooden strip and grasp the wooden strip, preventing the wooden strip from cracking when the nail 5 enters, effectively ensuring the construction quality and construction efficiency.
[0039] Embodiment 2
[0040] As Figure 6 shown, this embodiment provides a fastener using the fastening washer of Embodiment 1. This fastener includes a nail 5 and a washer body 1. The middle part of the washer body 1 protrudes upward to form a buffer boss 2. A nail hole 3 is opened in the middle of the buffer boss 2. The washer body 1 is fixed on the nail 5 through the nail hole 3, and specifically can be fixed at the tip of the nail 5 or the lower part of the nail rod. In addition, downward sharp corners 4 are provided around the washer body 1. When used for the fastening of wooden products, the sharp corners 4 will enter the wooden products and grasp the wooden products, thereby preventing the wooden products from cracking when the nail 5 enters.
[0041] When using the nail 5 to fasten wood products, the nail 5 is perpendicular to the wood products. Therefore, in this embodiment, it is preferred that the pointed corner part 4 is perpendicular to the washer body 1, so that the pointed corner part 4 can stably and reliably enter the wood products during fastening, thereby improving the grasping effect of the pointed corner part 4 on the wood products. Of course, on the premise of not affecting or having a small impact on the grasping effect, the pointed corner part 4 can also be slightly inclined in the vertical direction.
[0042] The washer body 1 in this embodiment mainly has the following two structures:
[0043] First, the washer body 1 has a circular structure, and when the washer body 1 has a circular structure, the pointed corner part 4 is integrally formed around the washer body 1.
[0044] Second, the washer body 1 has a polygonal structure, and when the washer body 1 has a polygonal structure, the pointed corner part 4 is formed by bending all / part of the corner parts of the washer body 1. It should be noted that when the washer body 1 has a polygonal structure, it can usually be a triangular structure, a quadrilateral structure, a pentagonal structure, a hexagonal structure, etc., and the pointed corner part 4 can be formed by bending all / part of the corner parts. For example, when the washer body 1 is a triangular structure, the pointed corner part 4 can be formed by bending the three corner parts of the washer body 1. When the washer body 1 is a quadrilateral structure, the pointed corner part 4 can be formed by bending the four corner parts or two diagonal corner parts of the washer body 1. When the washer body 1 is a hexagonal structure, the pointed corner part 4 can be formed by bending three spaced corner parts of the washer body 1.
[0045] Furthermore, the number of the above-mentioned pointed corner parts 4 is 2 - 6, specifically, it can be 2, 3, 4, 6, etc. However, to ensure a better grasping effect, it is preferred that the number of the pointed corner parts 4 is 4, so that a better grasping force can be generated on the wood products from all around, thereby effectively preventing the wood products from cracking.
[0046] The implementation principle of this embodiment is the same as that of Embodiment 1 and will not be elaborated here.
[0047] The above is only the specific implementation manner of the present utility model. Any feature disclosed in this specification, unless specifically described, can be replaced by other equivalent or similar-purpose alternative features; all the features disclosed, or all the steps in any method or process, except for mutually exclusive features and / or steps, can be combined in any way.
