Description

Technical Field

[0001] This utility model relates to the field of zipper slider technology, and in particular to a self-lubricating zipper slider structure. Background Technology

[0002] Zippers are fasteners that use a series of teeth to join or separate items. They are now widely used in clothing, bags, tents, and other products.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing zipper sliders lack a self-lubricating structure, resulting in dry friction between the inner wall of the slider and the metal or resin contact surface of the zipper teeth. The resistance generated during pulling is much greater than that under lubrication, causing the meshing tips of the zipper teeth to become blunt due to repeated friction. Gaps appear in the originally tight meshing relationship, leading to problems such as zipper loosening and easy slippage.

[0004] To address this, a self-lubricating zipper slider structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a self-lubricating zipper slider structure, which can solve the problem that existing zipper sliders lack a self-lubricating structure, resulting in the inner wall of the slider and the metal or resin contact surface of the zipper teeth being in a dry friction state. The resistance generated during the pulling process is much greater than that in a lubricated state, so the meshing tips of the zipper teeth become blunt due to repeated friction, and gaps appear in the originally tight meshing relationship, which in turn leads to problems such as loose zippers and easy slippage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating zipper slider structure, comprising a zipper slider body, a limiting mechanism being provided at the top of the zipper slider body, a lubrication mechanism being slidably connected to the inner side of the limiting mechanism, the lubrication mechanism comprising a mounting shell, a lubricating wax block, three sliding holes, three sliding rods, and a pushing block, the mounting shell being slidably connected to the inner side of the limiting mechanism, the lubricating wax block being installed at the top of the inner side of the mounting shell, the sliding holes being provided at the top of the limiting mechanism, the sliding rods being welded to the top of the mounting shell, the sliding rods being slidably connected to the inner side of the sliding holes, and the pushing block being welded to the top of the sliding rods.

[0007] Preferably, the limiting mechanism includes a limiting groove, a limiting shell, two fixing grooves, two limiting plates, three limiting screws, three limiting holes, and a limiting nut, wherein the limiting groove is formed on the inner side of the top of the zipper slider body.

[0008] Preferably, the limiting shell is movably connected to the inner side of the limiting groove, the mounting shell is slidably connected to the inner side of the limiting shell, the sliding hole is opened on the top of the limiting shell, and the fixing groove is opened on both sides of the top of the zipper slider body.

[0009] Preferably, the limiting plate is welded to both sides of the limiting shell, the limiting screw is welded to the top of the fixing groove, the limiting hole is opened on the surface of the limiting plate, the limiting hole is slidably connected to the surface of the limiting screw, and the limiting nut is threadedly connected to the top of the surface of the limiting screw.

[0010] Preferably, a reinforcing ring is welded at the connection between the sliding rod and the mounting shell, and the surface of the reinforcing ring is coated with an anti-corrosion coating.

[0011] Preferably, the surface of the push block is covered with a protective pad, and the surface of the protective pad is engraved with anti-slip texture.

[0012] Preferably, a connecting block is welded to the top of the zipper slider body, and a pull tab is rotatably connected to the rear side of the connecting block.

[0013] Preferably, the surface of the pull tab is covered with an anti-slip pad, which is made of silicone material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The limiting mechanism of this application provides a clear installation space and sliding guide for the mounting shell of the lubrication mechanism, preventing the mounting shell from shifting or shaking during zipper pulling. At the same time, the limiting shell is further limited in position by sliding connection between the limiting plates on both sides and the limiting screw in the fixing groove, ensuring that the lubrication mechanism is always in the working area corresponding to the chain teeth, ensuring that the lubricating wax can act on the chain teeth, and avoiding lubrication failure caused by mechanism misalignment. In addition, the detachable fixing method of limiting screw and limiting nut is adopted. When the lubricating wax is exhausted or the lubrication mechanism malfunctions, simply unscrew the limiting nut to remove the limiting shell and the internal lubrication mechanism from the limiting groove. After wax replacement or component repair, it can be reassembled and fixed without replacing the entire slider, which greatly simplifies the maintenance process and reduces the user's operating costs.

[0016] 2. The lubrication mechanism of this application allows the lubricating wax block inside the mounting housing to directly contact the zipper teeth. During zipper operation, the wax adheres evenly to the surface of the zipper teeth along with the relative movement between the zipper teeth and the lubrication mechanism, forming a durable lubricating film. This transforms the dry friction between the slider and the zipper teeth into lubricating friction, significantly reducing frictional resistance and wear rate. This continuous lubrication effect not only effectively reduces wear on the inner wall of the slider and the zipper teeth, extending the zipper's service life, but also avoids the jamming and abnormal noise problems caused by dry friction in traditional zippers, making the zipper open and close more smoothly. The effect is even more significant in environments that easily aggravate friction, such as low temperatures. The three sliding rods provide balanced guidance for the sliding of the mounting housing, and the push block at the top forms a convenient manual control structure. When the user feels that the zipper jamming is aggravated or the lubrication effect is weakened, they can directly press the push block, which pushes the mounting housing downward through the sliding rods, allowing the lubricating wax block to form a tight contact with the zipper teeth.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5The present invention provides the following technical solution:

[0025] A self-lubricating zipper slider structure includes a zipper slider body 1. A limiting mechanism 2 is provided on the top of the zipper slider body 1. A lubrication mechanism 3 is slidably connected to the inner side of the limiting mechanism 2. The lubrication mechanism 3 includes a mounting shell 31, a lubricating wax block 32, three sliding holes 33, three sliding rods 34, and a pushing block 35. The mounting shell 31 is slidably connected to the inner side of the limiting mechanism 2. The lubricating wax block 32 is installed on the top of the inner side of the mounting shell 31. The sliding holes 33 are provided on the top of the limiting mechanism 2. The sliding rods 34 are welded to the top of the mounting shell 31 and slidably connected to the inner side of the sliding holes 33. The pushing block 35 is welded to the top of the sliding rods 34.

[0026] In this embodiment: the zipper slider body 1 provides a stable mounting reference and support carrier for the limiting mechanism 2 and the lubrication mechanism 3. The mounting shell 31 serves as a dedicated container and mounting carrier for the lubricating wax block 32, providing a stable storage space for the wax block and preventing it from falling off or shifting. Furthermore, it slides in conjunction with the limiting shell 22, allowing the wax block to move longitudinally and adjust its contact with the zipper teeth. Through contact and friction with the zipper teeth, the lubricating wax block 32 continuously releases wax and adheres to the surface of the zipper teeth, forming a lubricating film and converting dry friction into lubricating friction. The sliding hole 33 serves as a sliding rod 34. The sliding rod 34 is provided with a through-path and a sliding channel to restrict its direction of movement and prevent the mounting housing 31 from shifting due to tilting or shaking of the sliding rod 34. As a transmission component connecting the mounting housing 31 and the push block 35, the sliding rod 34 transmits the pressing force of the push block 35 to the mounting housing 31, causing the mounting housing 31 to move longitudinally and adjust the contact between the lubricating wax block 32 and the chain teeth. The push block 35 provides a convenient operating carrier for the user, and its top pressing surface makes it easy for the user to apply external force. The sliding rod 34 drives the mounting housing 31 to move downward, increasing the contact pressure between the lubricating wax block 32 and the chain teeth.

[0027] Specifically, such as Figure 4 , Figure 5 As shown, the limiting mechanism 2 includes a limiting groove 21, a limiting shell 22, two fixing grooves 23, two limiting plates 24, three limiting screws 25, three limiting holes 26 and a limiting nut 27. The limiting groove 21 is opened on the inner side of the top of the zipper slider body 1.

[0028] Specifically, such as Figure 4 , Figure 5 As shown, the limiting shell 22 is movably connected to the inner side of the limiting groove 21, the mounting shell 31 is slidably connected to the inner side of the limiting shell 22, the sliding hole 33 is opened on the top of the limiting shell 22, and the fixing groove 23 is opened on both sides of the top of the zipper slider body 1.

[0029] Specifically, such as Figure 4 , Figure 5As shown, the limiting plate 24 is welded to both sides of the limiting shell 22, the limiting screw 25 is welded to the top of the fixing groove 23, the limiting hole 26 is opened on the surface of the limiting plate 24, the limiting hole 26 is slidably connected to the surface of the limiting screw 25, and the limiting nut 27 is threadedly connected to the top of the surface of the limiting screw 25.

[0030] In this embodiment: A limiting groove 21 provides installation and positioning space for the limiting shell 22, clearly defining its assembly position and preventing lateral displacement during use. The inner space of the limiting shell 22 guides the sliding of the mounting shell 31, limiting its range of motion and preventing misalignment between the lubricating wax block 32 and the chain teeth. The fixing groove 23 provides dedicated installation space for the limiting screw 25, making the welding of the limiting screw 25 more stable and preventing collision damage or interference with the operation of other components caused by exposed screws. The limiting plate 24 is welded to the limiting shell 22, forming a connection between the limiting shell 22 and the limiting... The connecting bridge of the screw 25 utilizes the limiting hole 26 on its surface to fit the limiting screw 25, thereby achieving lateral fixation of the limiting shell 22. The limiting screw 25, the limiting hole 26, and the limiting nut 27 cooperate to form a detachable fixing structure, enabling the limiting shell 22 to be stably installed in the limiting groove 21. The limiting hole 26, through sliding cooperation with the screw, not only enables the detachable assembly of the limiting shell 22 but also restricts the lateral displacement of the limiting shell 22, ensuring the fixing effect of the limiting mechanism 2. The limiting nut 27 is threadedly connected to the limiting screw 25, and the tightening force presses and fixes the limiting plate 24, thereby locking the limiting shell 22.

[0031] Specifically, such as Figure 2 As shown, a reinforcing ring 4 is welded at the connection between the sliding rod 34 and the mounting shell 31, and the surface of the reinforcing ring 4 is coated with an anti-corrosion coating.

[0032] Specifically, such as Figure 5 As shown, a protective pad 5 is fitted on the surface of the push block 35, and the surface of the protective pad 5 is engraved with anti-slip texture.

[0033] In this embodiment: by setting a reinforcing ring 4, the contact area between the two is increased, the structural strength of the welded part is enhanced, and the root breakage of the sliding rod 34 due to repeated sliding and pressing is avoided. By setting an anti-corrosion coating, it can resist the erosion of sweat, rainwater, etc., prevent the reinforcing ring 4 from rusting and being damaged, and extend the connection life of the sliding rod 34 and the mounting shell 31. By setting a protective pad 5, the hand comfort when pressing is increased, and discomfort caused by direct contact of the hand with the hard push block 35 is avoided. By setting an anti-slip texture, the friction between the hand and the push block 35 is increased, and slippage is prevented when pressing.

[0034] Specifically, such as Figure 1 As shown, a connecting block 6 is welded to the top of the zipper slider body 1, and a pull tab 7 is rotatably connected to the rear side of the connecting block 6.

[0035] Specifically, such as Figure 1 As shown, the surface of the pull tab 7 is covered with an anti-slip pad 8, which is made of silicone material.

[0036] In this embodiment: By setting a connecting block 6 as a connecting medium between the pull tab 7 and the zipper slider body 1, and by welding and fixing it to the top of the slider body, a stable rotation support point is provided for the pull tab 7. By setting the pull tab 7, a grip structure is provided for the user to pull the slider. By rotating and connecting with the connecting block 6, the grip angle can be flexibly adjusted to adapt to different usage postures. By setting an anti-slip pad 8, the friction is increased to prevent the hand from slipping when pulling. By setting the anti-slip pad 8 to be made of silicone material, the soft properties of silicone are used to improve grip comfort and alleviate the discomfort of holding for a long time.

[0037] Working principle: First, the operator inserts the limiting shell 22 into the limiting groove 21 of the zipper slider body 1, and passes the limiting screw 25 through the limiting hole 26. At this time, the operator tightens the limiting nut 27 to achieve a stable installation of the limiting shell 22. Next, after assembly, the lubricating wax block 32 in the mounting shell 31 is in the position corresponding to the zipper teeth. At this time, the lubricating wax block 32 and the teeth are close to each other, waiting for lubrication to be triggered. Then, when the user feels that the zipper is stuck or the lubrication effect is weakened, he / she presses the pushing block 35 by hand. The force of the pushing block 35 is transmitted to the mounting shell 31 through the three evenly distributed sliding rods 34, causing the mounting shell 31 to slide down along the inner side of the limiting shell 22. The movement causes the lubricating wax block 32 to come into close contact with the chain teeth. The wax on the surface of the wax block is transferred to the surface of the chain teeth under the contact pressure, quickly forming a lubricating film. Then, the user holds the pull tab 7 and pulls the zipper slider body 1. During the movement of the zipper slider body 1, the chain teeth and the lubricating wax block 32 rub against each other naturally, continuously and evenly adhering the wax to the surface of the chain teeth, maintaining the integrity of the lubricating film, and converting the dry friction between the slider and the chain teeth into lubricating friction. Finally, when the lubricating wax block 32 is gradually consumed, the user can unscrew the limit nut 27, remove the limit shell 22 and the internal lubrication mechanism 3, replace the new lubricating wax block 32, and then reset and fix the parts according to the original assembly steps to complete the replenishment of the lubricating medium.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
