Description

Technical Field

[0001] This utility model relates to the field of zippers, specifically an anti-knock-off zipper. Background Technology

[0002] A zipper consists of two chain straps and a zipper pull. The chain straps have a row of metal or plastic teeth that act as a latch to secure the opening. The sliding zipper pull pulls the two rows of teeth into the latch, thus closing the opening. Zippers are typically used to fasten the front of garments, allowing the garment to close completely.

[0003] The patent with publication number CN220174622U discloses an anti-slip chain. The zipper head is slidably connected to two chain belts. A fixed base is mounted on the surface of the zipper head, which is divided into an upper zipper head and a lower zipper head. The upper and lower zipper heads are matched in position, size, and shape, and both have corresponding through grooves on their surfaces. A connecting rod is installed inside the through grooves of the upper and lower zipper heads, and a second spring is installed inside the connecting rod. A locking plate is installed at the end of the second spring, and a second locking block is installed on the surface of the locking plate. A through groove matching the position and size of the second locking block is also present on the surface of the connecting rod. This design allows for easy disassembly of the zipper head. If it gets stuck during use, the connecting rod can be pulled out by pressing the second locking block, thus disassembling the zipper head. However, in the above-mentioned zipper, the zipper head and the part of the chain belt near the top of the zipper head may not remain parallel during use, so jamming may still occur when pulling the zipper head. Therefore, an anti-slip chain is proposed to address the above problem. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and avoid the problem of the zipper slipping and getting stuck on the chain, this utility model proposes an anti-slip chain.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an anti-knock chain, including a left chain belt and a right chain belt, a pull head is slidably connected to the surface of the right chain belt, a flattening component is provided at the bottom of the right chain belt, and a lubrication component is provided on the rear side of the pull head;

[0007] Preferably, the slid head is adapted to slide on the surface of the left chain, and the end of the straight plate away from the connecting rod is fixedly connected to the rear side inside the slid head. During the pulling of the slid head, the top of the slid head pulls the right chain through the combination of the straight plate, connecting rod and slider, so that the two parts of the right chain near the front and rear of the slid head remain flat and do not bend. That is, at this time, the bottom of the slid head and the part of the right chain near the rear of the slid head are parallel, and there will be no jamming during the pulling of the slid head.

[0008] Preferably, a groove is provided on the right side of the slider, and the connecting rod extends through the groove into the interior of the slider.

[0009] Preferably, the lubrication assembly includes a connecting sleeve fixedly installed in the middle of the rear side of the pull head. A hollow tube is fixedly connected to the front side of the connecting sleeve. A hollow tube is slidably connected inside the hollow tube. A pressure spring is fixedly connected to the rear end of the hollow tube. A clamping tube is slidably connected inside the hollow tube. Solid wax is clamped inside the clamping tube. A pressure spring is fixedly connected to the rear end of the clamping tube. Side grooves are provided on both the left and right sides inside the hollow tube.

[0010] Preferably, the second hollow tube extends to the outside of the first hollow tube, and the end of the first pressure spring away from the second hollow tube is fixedly connected to the inner wall of the first hollow tube.

[0011] Preferably, the solid wax extends to the outside of the hollow tube II, and the solid wax is adapted to contact the adjacent parts of the left and right chain belts. The end of the pressure spring II away from the clamping tube is fixedly connected to the inner wall of the hollow tube II, and the solid wax can lubricate the connection between the left and right chain belts.

[0012] Preferably, the side groove is located inside the hollow tube II, and a protrusion that is slidably connected to the inside of the side groove is fixedly installed on the surface of the tube clamp. The protrusion can ensure that the tube clamp slides stably inside the hollow tube II, while preventing the tube clamp from moving out of the hollow tube II.

[0013] The advantages of this utility model are:

[0014] This invention achieves this by having the zipper pull the right chain near its rear side during the zipper pull process, keeping the two parts of the right chain near the front and rear of the zipper pull flat. At this time, the two parts of the right chain near the front and rear of the zipper pull are parallel to the rear end of the zipper pull, and there will be no jamming during the zipper pull process.

[0015] In addition, during the process of pulling the slider, the solid wax inside the slider lubricates the adjacent areas of the left and right chains, thereby reducing the friction of the slider sliding on the surfaces of the left and right chains. It also prevents wear on the teeth of the left and right chains, thus making the slider slide more smoothly. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses an anti-knock chain. (Refer to...) Figure 1An anti-knock chain includes a left chain belt 11 and a right chain belt 12. A pull head 2 is slidably connected to the surface of the right chain belt 12. A leveling component 3 is provided at the bottom of the right chain belt 12. A lubrication component 4 is provided at the rear side of the pull head 2.

[0027] Reference Figures 2-4 The leveling component 3 includes an L-shaped metal block 31 fixedly installed at the bottom of the right chain belt 12. The upper and lower ends of the L-shaped metal block 31, away from the right chain belt 12, are provided with grooves 32. A slider 33 is slidably connected to the surface of the L-shaped metal block 31 on the side away from the right chain belt 12. A connecting rod 34 is fixedly connected to one end of the slider 33 near the inside of the pull head 2. A groove is provided on the right side of the pull head 2, through which the connecting rod 34 extends into the interior of the pull head 2. A straight plate 35 is fixedly connected to the rear end of the connecting rod 34. The pull head 2 is adapted to slide... The left chain belt 11 is dynamically connected to the surface of the left chain belt 11. The end of the straight plate 35 away from the connecting rod 34 is fixedly connected to the rear side inside the slider 2. During the process of pulling the slider 2, the top of the slider 2 pulls the right chain belt 12 through the combination of the straight plate 35, the connecting rod 34 and the slider 33, so that the two parts of the right chain belt 12 near the front and rear sides of the slider 2 remain flat and do not bend. That is, at this time, the bottom end of the slider 2 and the part of the right chain belt 12 near the rear side of the slider 2 remain parallel. At this time, there will be no jamming during the process of pulling the slider 2.

[0028] Reference Figures 5-6 The lubrication assembly 4 includes a connecting sleeve 41 fixedly installed in the middle of the rear side of the pull head 2. A hollow tube 42 is fixedly connected to the front side of the connecting sleeve 41. A hollow tube 43 is slidably connected inside the hollow tube 42. A pressure spring 44 is fixedly connected to the rear end of the hollow tube 43. The hollow tube 43 extends to the outside of the hollow tube 42. The end of the pressure spring 44 away from the hollow tube 43 is fixedly connected to the inner wall of the hollow tube 42. A retaining tube 45 is slidably connected inside the hollow tube 43. Solid wax 46 is retained inside the retaining tube 45. A pressure spring 47 is fixedly connected to the rear end of the retaining tube 45. The solid wax 46 extends... Outside the hollow tube 43, the solid wax 46 and the left chain belt 11 and right chain belt 12 are in contact with each other. The end of the pressure spring 47 away from the clamping tube 45 is fixedly connected to the inner wall of the hollow tube 43. The solid wax 46 can lubricate the connection between the left chain belt 11 and right chain belt 12. The hollow tube 43 has inner grooves on both the left and right sides. The side groove 48 is located inside the hollow tube 43. The surface of the clamping tube 45 is fixedly installed with a protrusion that slides inside the side groove 48. The protrusion can ensure that the clamping tube 45 slides stably inside the hollow tube 43, while preventing the clamping tube 45 from moving out of the hollow tube 43.

[0029] Working principle: When the operator needs to pull the zipper, the part of the zipper head 2 away from the right chain belt 12 is fitted onto the surface of the left chain belt 11. Then, the operator pulls the zipper head 2 backward. During this pulling process, the front part of the zipper head 2 connects with the left chain belt 11 and the right chain belt 12, while the rear part of the zipper head 2 is located between the separated left and right chain belts 11 and 12. As the operator pulls the zipper head 2, it drives the straight plate 35, connecting rod 34, and slider 33 to move. The slider 33 slides on the surface of the L-shaped metal block 31, and its movement within the groove 32 keeps the slider in place. The stability of the slider 33 sliding on the surface of the L-shaped metal block 31 is improved. Therefore, during the process of pulling the slider 2, the rear end of the slider 2 pulls the right chain 12 of the separated part, so that the right chain 12 of the separated part and the right chain 12 connected to the left chain 11 at this time remain flat. That is, the right chain 12 of the separated part and the right chain 12 connected to the left chain 11 as a whole are parallel to the bottom end surface of the slider 2. Therefore, during the process of pulling the slider 2, the opening at the rear end of the slider 2 and the separation point of the left chain 11 and the right chain 12 are reduced, thus making the pulling of the slider 2 smoother.

[0030] Furthermore, during the pulling of the slider 2, the elastic force of the pressure spring 44 pushes the hollow tube 43 towards the part where the left chain belt 11 and the right chain belt 12 are about to connect. At the same time, the elastic force of the pressure spring 47 pushes the clamp tube 45 and the solid wax 46 towards the part where the left chain belt 11 and the right chain belt 12 are about to connect, thus causing the solid wax 46 to come into contact with the left chain belt 11 and the right chain belt 12. During the pulling of the slider 2, the slider 2 will drive the left chain belt 11 and the right chain belt 12 to gradually connect, and at the same time, the solid wax 46 will lubricate the part where the left chain belt 11 and the right chain belt 12 are gradually connected. During the consumption process, the elastic force of the pressure spring 47 will push the end of the solid wax 46 away from the clamp tube 45 to always contact the connection between the left chain belt 11 and the right chain belt 12, thereby ensuring that the connection between the left chain belt 11 and the right chain belt 12 is constantly lubricated, thereby reducing the friction when the slider 2 slides on the surface of the left chain belt 11 and the right chain belt 12. In addition, it can avoid wear on the teeth of the left chain belt 11 and the right chain belt 12 when the slider 2 slides, thus making the slider 2 slide more smoothly. When the solid wax 46 is consumed, the operator can use tools such as tweezers to pick up new solid wax 46, put it back and clamp it into the inside of the clamp tube 45.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
