Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, and more specifically, to a locking structure, a zipper block, a pin, a zipper end stop, and a zipper. Background Technology
[0002] Zippers are accessories used in clothing. A zipper consists of a slider, top stop, fabric tape, and teeth. In conventional zippers, the pin, zipper block, and zipper end stop are mostly made of zinc alloy or injection-molded plastic, which has a low production cost and only requires pressing and locking with the fabric tape during assembly.
[0003] In practical use, a punch is typically used to press the pressure-bearing surfaces of accessories such as pins, zipper blocks, and zipper ends. Under the pressure of the punch, these surfaces deform, clamping the fabric and locking the accessories to the tape. However, when the pressure-bearing surfaces deform, the limited extensibility of the accessory material causes the surface and protective layers to tear, such as electroplating and paint layers. Therefore, when accessories are deformed by the punch, the protective layer on the surface of the accessory material will be damaged, resulting in direct exposure of the material. After long-term use, or in environments with high salt spray content, the exposed material will be oxidized or corroded, causing a change in material color and affecting the performance of the accessories.
[0004] In summary, how to solve the problem of tearing and damage to the surface and protective layer of the accessory material caused by the assembly and locking of the accessory and the tape is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a locking structure that, by setting a groove, forms a cantilever beam-shaped stress plate on the pressing force surface, and a protective layer can be applied to its side surface, and the cross-sectional area of the deformation position and the connection position of the accessory itself is reduced, so as to reduce the deformation of the material, reduce the damage to the material surface and protective layer, and avoid material exposure and corrosion.
[0006] The second objective of this invention is to provide a zipper block that includes the above-mentioned locking structure, has the same technical features, and can solve the same technical problem.
[0007] The third objective of this utility model is to provide a pin bar that includes the above-mentioned locking structure, has the same technical features, and can solve the same technical problem.
[0008] The fourth objective of this utility model is to provide a zipper end stop that includes the above-mentioned locking structure, has the same technical features, and can solve the same technical problem.
[0009] The fifth objective of this utility model is to provide a zipper that includes at least one of the above-mentioned zipper block, pin, and zipper end stop, has the same technical features, and can solve the same technical problem.
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A locking structure, comprising:
[0012] The main body includes a C-shaped insertion tube, which includes at least one pressure-bearing surface;
[0013] A groove is provided through the pressing force surface to form at least one force-bearing piece on the pressing force surface, the force-bearing piece being connected to the pressing force surface in the form of a cantilever beam.
[0014] Preferably, the groove surrounds the non-connected position between the stress-bearing plate and the pressing surface.
[0015] Preferably, the width L of the groove is not less than 0.5 mm.
[0016] Preferably, the force-bearing plate is circular in shape, and a cantilever extends from the outer periphery of the force-bearing plate to connect with the pressing force-bearing surface.
[0017] Preferably, the force-bearing piece is polygonal in shape, with only one side of it connecting to the pressing force-bearing surface.
[0018] Preferably, the two sides or the middle surface of the cannula are the pressure-bearing surfaces;
[0019] The groove is provided on at least one of the pressing force-bearing surfaces.
[0020] A zipper block for inserting a pin into a zipper;
[0021] The zipper block includes any of the locking structures described above.
[0022] A pin for engaging with a zipper block inside a zipper;
[0023] The pin includes any of the locking structures described above.
[0024] A zipper end stop is provided at the end of the zipper and is used to limit the end of the zipper pull;

[0026] A zipper, comprising the zipper block described above;
[0027] Or the aforementioned pin;
[0028] Or the zipper stop mentioned above.
[0029] The locking structure provided by this utility model has at least the following advantages compared with the prior art:
[0030] 1. By setting grooves on the pressing surface to form a cantilever beam-shaped stress plate, the cross-sectional area at the connection point between the stress plate and the pressing surface is reduced. This allows the stress plate to deform only at the connection point when it is pressed by the punch, thereby reducing the deformation of the material, reducing the probability of damage to its surface and protective layer, and preventing the material from being oxidized and corroded.
[0031] 2. Since the stress-bearing plate is formed by setting through grooves on the pressure-bearing surface, the side walls of the stress-bearing plate, i.e. the positions that were torn in the original design, can be pre-set with protective layers, thereby reducing the exposed material surface after assembly and avoiding material oxidation and corrosion.

[0044] The core of this utility model is to provide a locking structure. By setting a groove, a cantilever beam-shaped stress plate is formed on the pressing force surface.

[0049] Please refer to Figures 1-3 A locking structure, comprising:
[0050] The main body includes a C-shaped insertion tube, which includes at least one pressing force-bearing surface 1;
[0051] The groove 3 is provided through the pressing force surface 1 and is used to form at least one force plate 2 on the pressing force surface 1. The force plate 2 is connected to the pressing force surface 1 in the form of a cantilever beam.
[0052] like Figures 4-6As shown, the locking structure includes a tube with a C-shaped cross-section. When the tube is assembled with the fabric tape, the fabric tape is simply inserted along the opening on the side of the tube, and then a punch is used to press the tube radially to deform it, thereby pressing and clamping the fabric tape inside the tube, thus completing the assembly of the tube and the fabric tape.
[0053] The insertion tube includes a pressing force-bearing surface 1, which is used to deform under the pressure of the punch and thus press the fabric tape in the insertion tube. A groove 3 is provided on the surface of the pressing force-bearing surface 1, and the groove 3 is a through groove, so that a cantilever beam-shaped force-bearing piece 2 is formed on the pressing force-bearing surface 1. That is, the force-bearing piece 2 is connected to the insertion tube at only one end, which effectively reduces the cross-sectional area at the connection position between the force-bearing piece 2 and the insertion tube. When the force-bearing piece 2 is pressed by the punch, since there is a groove 3 between the outer periphery of the force-bearing piece 2 and the pressing force-bearing surface 1, only the connection position between the force-bearing piece 2 and the pressing force-bearing surface 1 is deformed, thereby reducing the deformation of the main material and effectively reducing the probability of tearing and damage to the surface of the main material and its surface protective layer, and avoiding oxidation and corrosion of the main material.
[0054] Meanwhile, the area where the main body is prone to tearing when squeezed is replaced by the groove 3. The side wall of the groove 3 is the side surface of the stress plate 2 and the pressing stress surface 1. This area can be processed together with the main body surface to form a protective layer, such as an electroplating layer and a paint layer, thereby increasing the corrosion resistance during use.
[0055] In some embodiments, the groove 3 surrounds the non-connected position between the force-bearing piece 2 and the pressing force-bearing surface 1.
[0056] like Figures 4-6 As shown, the groove 3 has a semi-enclosed structure that surrounds the force-bearing plate 2. If the groove 3 is U-shaped or H-shaped, the force-bearing plate 2 is connected to the pressing force-bearing surface 1 at only one end, and the rest of the position is separated from the pressing force-bearing surface 1 through the groove 3. Because the non-connected positions of the force-bearing plate 2 and the pressing force-bearing surface 1 are all in an enclosed state, the pressing force-bearing surface 1 around the force-bearing plate 2 can protect the cantilever beam-shaped force-bearing plate 2, and prevent the insertion tube from being deformed by external force, thereby avoiding the difficulty of assembling the locking structure and the tape due to the deformation of the force-bearing plate 2.
[0057] In some embodiments, the groove 3 extends to the opening side of the insertion tube, that is, the groove 3 does not form a semi-enclosed structure to wrap the force-bearing piece 2, so that the end of the force-bearing piece 2 away from the pressure-bearing surface 1 is not surrounded by the groove 3. At this time, the side surface of the force-bearing piece 2 away from the pressure-bearing surface 1 is the original side surface of the insertion tube opening side. At this time, it can still achieve the effect of reducing the deformation of the main body during assembly. However, it is worth noting that since the cantilever beam-shaped force-bearing piece 2 has an unwrapped end face, it is easily subjected to external forces, causing the cantilever beam-shaped force-bearing piece 2 to deform. As a result, when assembling with the fabric tape, the force-bearing piece 2 does not have a fixed relative positional relationship with the punch and the fabric tape, resulting in a decrease in assembly accuracy and affecting the final assembly effect.
[0058] In some embodiments, the width L of the groove 3 is not less than 0.5 mm.
[0059] The surface of the main body is provided with a protective layer, preferably an electroplated layer and / or a paint layer, which can effectively inhibit the surface oxidation and corrosion of the main body material. When manufacturing the tank 3, the treatment of the protective layer on the inner wall of the tank 3 needs to be considered. That is, the width L of the tank 3 must be not less than 0.5mm so that when the main body is electroplated or painted, the electroplating liquid or paint liquid can enter the tank 3 and come into contact with the inner wall of the tank 3, thereby forming an effective protective layer on the inner wall of the tank 3. When the width L of the tank 3 is less than the preset value, the electroplating liquid or paint liquid cannot come into effective or sufficient contact with the tank 3, and thus cannot form an effective protective layer on the inner wall of the tank 3. As a result, in subsequent use, there will be oxidation or corrosion on the side wall of the tank 3, affecting the performance and appearance of the product.
[0060] In some embodiments, the force-bearing plate 2 is circular, and a cantilever extends from the outer periphery of the force-bearing plate 2 to connect with the pressing force-bearing surface 1.
[0061] like Figure 3 As shown, the stress-bearing plate 2 on the left is circular and has a cantilever at the top. One end of the cantilever is connected to the pressing stress-bearing surface 1. When the stress-bearing plate 2 is subjected to force, the position of its cantilever deforms, thus avoiding damage to the protective layer caused by the deformation of the stress-bearing plate 2 itself.
[0062] In some embodiments, the force-bearing piece 2 is polygonal in shape, with only one side of it connecting to the pressing force-bearing surface 1.
[0063] like Figure 3 As shown, the force-bearing plate 2 on the right is triangular, with its upper side edge connecting to the pressing force-bearing surface 1, or as shown in the figure. Figure 1 and Figure 2 As shown, the stress-bearing piece 2 is rectangular, and its upper or lower side is connected to the pressing stress-bearing surface 1. When the stress-bearing piece 2 is compressed, only the connection position deforms, effectively reducing the deformation position and lowering the probability of damage to the surface protective layer.
[0064] likeFigure 2 As shown, the groove 3 is H-shaped, simultaneously generating two cantilever beam-shaped force-bearing plates 2. Alternatively, multiple U-shaped grooves 3 can be set on a single pressing force-bearing surface 1, thereby forming multiple force-bearing plates 2 with the same direction on the pressing force-bearing surface 1. Figure 3 As shown, the groove 3 is C-shaped or V-shaped, which generates a circular or triangular force-bearing plate 2. During assembly, a punch with the same shape as the force-bearing plate 2 is selected first to punch the force-bearing plate 2, thereby causing the force-bearing plate 2 to deform relative to the pressing force-bearing surface 1, and pressing and fixing the cloth tape inside the insertion tube.
[0065] In practical implementation, the connection position between the cantilever beam-shaped load-bearing plate 2 and the pressing load-bearing surface 1 can be as follows: Figure 1 The upper surface shown can also be as follows: Figure 2 The upper or lower end face shown can also be as follows: Figure 5 The left or right end face shown forms a force-bearing piece 2 that can deform in different directions. The connection position between the force-bearing piece 2 and the pressing force-bearing surface 1 can be designed according to the locking relationship between the insertion tube and the cloth tape. Different connection positions can enable the force-bearing piece 2 to obtain different deformation directions, all of which can achieve locking between the insertion tube and the cloth tape.
[0066] In some embodiments, the effective force-bearing area of the force-bearing plate 2 is not less than the effective force-applying area of the punch.
[0067] During implementation, the stress plate 2 is deformed by punching and then locked with the fabric belt. Therefore, during punching, the punch should be kept away from the pressing surface 1 around the stress plate 2 to avoid deformation of the pressing surface 1 around the stress plate 2, thereby reducing the overall deformation of the main material and reducing damage to the surface protective layer of the main body, so as to ensure the oxidation resistance and corrosion resistance of the main body.
[0068] Therefore, when designing the force-bearing plate 2, it should be ensured that the effective force-bearing area of the force-bearing plate 2 in contact with the punch is not less than the effective force-applying area of the punch.
[0069] In some embodiments, the two sides or the middle surface of the cannula are the pressure-bearing surfaces 1;
[0070] At least one of the pressing surfaces 1 is provided with a groove 3.
[0071] like Figures 4-6 As shown, the cross-section of the cannula is C-shaped, therefore it includes two side surfaces and one middle surface, at least one of which is the pressure-bearing surface 1, as shown. Figure 4 As shown, one side is the pressure-bearing surface 1. The punch can then press the pressure-bearing piece 2 from one side, causing it to deform. This, combined with the other side, completes the pressing and fixing of the fabric strip. Alternatively, it can be as follows: Figure 5As shown, both sides are pressure-bearing surfaces 1. At this time, the punch can press the pressure-bearing pieces 2 from both sides, causing the pressure-bearing pieces 2 on both sides to deform simultaneously, thus completing the pressing and fixing of the fabric strip; it can also be as follows... Figure 6 As shown, the middle surface serves as the pressing force-bearing surface 1, and the punch presses the force-bearing plate 2 from the side. This, combined with the blocking part 4 that extends inward from the opening side of the insertion tube in a closing trend, completes the pressing and fixing of the cloth strip inside the insertion tube.
[0072] In practical use, the side closest to the inside of the zipper is generally selected as the pressing force surface 1, which can ensure that the outer surface of the locking structure is flat, thereby improving the overall aesthetics of the product.
[0073] like Figures 1-3 As shown, in addition to the locking structures disclosed in the above embodiments, this utility model also provides a zipper block including the above-mentioned locking structure for inserting the zipper inner pin 5. The zipper block includes an insert tube and a block body below, which are fixedly connected.
[0074] In addition to the locking structures disclosed in the above embodiments, this utility model also provides a pin 5 including the above-mentioned locking structure for insertion into the zipper block inside the zipper.
[0075] like Figures 4-6 As shown, in addition to the locking structures disclosed in the above embodiments, this utility model also provides a zipper end stop including the above-mentioned locking structure, which is disposed at the end of the zipper and used to limit the end of the zipper pull.
[0076] In addition to the zipper block, connector, and zipper stop disclosed in the above embodiments, this utility model also provides a zipper that includes any one of the above-mentioned zipper block, connector, and zipper stop.
