Description

Technical Field

[0001] The utility model relates to the technical field of copper rivets, in particular to a strong copper rivet that is anti-falling off. Background Art

[0002] Metal rivets can be divided into: covered rivets, straw hat rivets, reverse cap rivets, double-sided rivets, single-sided rivets, mushroom rivets, conical rivets, two-color rivets, drilled rivets, mushroom rivets, pointed rivets. The main materials of metal rivets are copper, zinc alloy, aluminum, etc. They are mainly used for stitching the edges and corners of thicker fabrics to make clothes more beautiful and elegant. For example, they come in various shapes and sizes on jeans, backpacks, jacket pockets and other clothing. They are of different shapes and sizes and in many colors. Metal rivets are used on jeans.

[0003] For example, a rivet with application number CN201520145199.7 includes a rivet cover and a rivet base, wherein the rivet cover is an integrated structure, and a clamping portion for the rivet base to be clamped is provided on the side of the rivet cover close to the rivet base, and the rivet cover and the rivet base can be fixedly connected. The rivet provided by the utility model utilizes the integrated structure of the rivet cover. During installation, only the rivet cover and the rivet base need to be assembled, which reduces the number of assembly parts and can effectively improve the installation efficiency. In addition, since the number of assembly parts is reduced, the material cost is effectively saved. Moreover, since the rivet has fewer reverse convex beads than the rivets in the prior art, the distance between the rivet cover and the fabric is effectively reduced, which significantly improves the aesthetics of the product. However, when the copper rivet passes through the fabric layer and enters the cover, it is difficult for it to be in the center position and is prone to deviation, which makes the copper rivet body easy to loosen.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a strong copper rivet that prevents falling off is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a strong copper nail that prevents falling off, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a strong copper rivet that prevents falling off, comprising a cover surface and a sharp nail body, the sharp nail body being fixedly connected to one side of the cover surface, and a fabric layer being inserted into the outside of the sharp nail body, an embedded block being provided on the outside of the sharp nail body, and a spring being sleeved on the outer surface of the sharp nail body, and a first squeezing ball being provided on the top of the spring.

[0007] Preferably, a second squeezing ball is provided on a side of the top of the spring that is symmetrical to the first squeezing ball, and a movable cap is sleeved on the outside of the second squeezing ball.

[0008] Preferably, a pressing arm is provided at the bottom of the insert block, and the bottom of the pressing arm is fixedly connected to the pressing block.

[0009] Preferably, a limiting groove is provided inside the pressing block, and the limiting groove is movably connected to the limiting block.

[0010] Preferably, the vertical center line of the insert is consistent with the vertical center line of the spring, and the spike body is engaged with the movable cap to drive the movable cap to move up and down.

[0011] Preferably, the movable cap contacts the inner wall of the insert and moves based on the inner wall of the insert.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model uses the arrangement of a spring and a squeezing ball. When the spike body passes through the fabric layer and connects to the insert, the squeezing ball secures the spike body. Without applying downward force to the spring, the squeezing ball will not loosen. On the contrary, the more the spike body is pulled upward, the greater the force exerted by the squeezing ball on the spike body, keeping the spike more stable and preventing it from falling off.

[0014] 2. The utility model sets a limiting groove and a limiting block inside the pressing block. When the spike body passes through the pressing block, the spike body is rotated and the limiting block is rotated to the inside of the limiting groove. The pressing block fixes the middle part of the spike body. The limiting groove and the extrusion ball form a double reinforcement mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 2 As shown, a strong copper rivet that prevents falling off includes a cover surface 1 and a sharp nail body 2, characterized in that the sharp nail body 2 is fixedly connected to one side of the cover surface 1, and the outside of the sharp nail body 2 is interspersed with a fabric layer 3, the outside of the sharp nail body 2 is provided with an insert 4, and the outer surface of the sharp nail body 2 is sleeved with a spring 5, and the top of the spring 5 is provided with a first squeezing ball 6, the cover surface 1 is a copper surface, which has a decorative effect and is not easy to fade, the cover surface 1 and the insert 4 are located on the upper and lower sides of the fabric layer 3 to fix the fabric layer 3, and the spring 5 provides a movable space for the first squeezing ball 6.

[0022] like Figure 3-Figure 4 As shown, a second squeezing ball 7 is provided on the side of the top of the spring 5 that is symmetrical to the first squeezing ball 6, and a movable cap 8 is sleeved on the outside of the second squeezing ball 7. The first squeezing ball 6 is a small steel ball. The first squeezing ball 6 and the second squeezing ball 7 fix the spike body 2 so that the spike body 2 is located at the center of the insert 4 to maintain the stability of the spike body 2.

[0023] Furthermore, a pressing arm 9 is provided at the bottom of the insert 4, and a pressing block 10 is fixedly connected to the bottom of the pressing arm 9. The pressing arm 9 is made of plastic. Pressure is applied to the pressing arm 9 so that the pressing block 10 and the pressing arm 9 press the movable cap 8 downward together.

[0024] Furthermore, a limiting groove 11 is opened inside the pressing block 10, and the limiting groove 11 is movably connected to the limiting block 12. The inner surface of the pressing block 10 is a hollow layer. When the limiting groove 11 enters the pressing block 10, the spike body 2 is rotated, and the limiting block 12 enters the inside of the hollow layer to fix the middle end of the spike body 2.

[0025] Furthermore, the vertical center line of the insert 4 is consistent with the vertical center line of the spring 5, the spike body 2 is engaged with the movable cap 8, driving the movable cap 8 to move up and down, the movable cap 8 is in contact with the inner wall of the insert 4, and moves on the inner wall of the insert 4. The first squeezing ball 6 and the second squeezing ball 7 are located between the movable cap 8 and the spring 5. The spring 5 drives the first squeezing ball 6 and the second squeezing ball 7, and the spike body 2 can be quickly removed.

[0026] Working principle: When using the anti-falling strong copper rivet, first pass the sharp nail body 2 at the bottom of the cover 1 through the fabric layer 3. When the sharp nail body 2 is inserted into the spring 5 inside the insert 4, the first squeezing ball 6 and the second squeezing ball 7 squeeze and fix the sharp nail body 2. Then, when the sharp nail body 2 needs to be removed from the inside of the fabric layer 3, press the pressing arm 9 downward to make the pressing block 10 press the movable cap 8. Finally, the movable cap 8 presses the first squeezing ball 6 and the second squeezing ball 7. With the help of the spring 5, the first squeezing ball 6 and the second squeezing ball 7 are loosened, and the sharp nail body 2 can be taken out to separate the copper rivet body from the fabric layer 3. This is the working principle of the anti-falling strong copper rivet.
