[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0051] The core of the present invention is to provide a slider assembly and a zipper including the slider assembly, which are more convenient to open and close.

[0052] For the specific embodiment of the slider assembly provided by the present invention, please refer to Figures 1 to 12 , including a pull head 3, a movable pin 2 and a block structure 1.

[0053] like Figure 1 As shown, the upper bottom plate groove 311 is provided on the upper bottom plate 31 of the slider 3, and can specifically pass through the lower bottom plate 31 of the slider. Figure 5 As shown, a front end protrusion 28 is provided on the movable pin 2. The upper base plate groove 311 is fixedly connected to the front end protrusion 28 to play a limiting role, so that the movable pin 2 can better drive the slider 3 to slide backward. Figure 7 and Figure 8 As shown, the block structure 1 includes a block body 12, and a socket 121 is provided on the block body 12. The block structure 1 is also provided with a fixed pin 11 fixed to the front end of the block body 12, and the fixed pin 11 is used to match the movable pin 2 and be inserted into the slider cavity 32 in parallel.

[0054] When applied to zippers, refer to Figures 10 to 12 , two chain tooth belts 4, the rear end of one chain tooth belt 4 is fixedly connected to the movable pin 2, and the rear end of the other chain tooth belt 4 is fixedly connected to the block structure 1. In the process of zipping, as Figure 10 As shown, there is no need to pull the slider 3 to the state of being in contact with the block 12 in sequence. The movable pin 2 can be directly inserted into the front end of the slider cavity 32 of the slider 3 so that the front end protrusion 28 extends upward into the upper bottom plate groove 311. When the front end protrusion 28 extends into the upper bottom plate groove 311, the movable pin 2 is directly pushed backward, and the slider 3 can be driven by the movable pin 2 to move backward toward the insertion hole 121. Figure 11 As shown, during the movement of the movable pin 2 in the socket 121, the movable pin 2 can cooperate with the socket 121 to make the front end protrusion 28 escape from the upper bottom plate groove 311, and after the escape, as shown in FIG. Figure 12 As shown, the pull head 3 can move forward to disengage the movable pin 2 and the block structure 1 , and the two chain tooth belts 4 can be engaged with each other under the action of the pull head 3 .

[0055] It can be seen that in this embodiment, based on the plug-in fit of the movable pin 2 and the slider 3, during the pulling and closing process, there is no need to move the slider 3 backward to fit with the block body 12, and then insert the movable pin 2 into the slider cavity 32 and the socket 121 of the block body 12 in turn. Instead, there is no need to adjust the positional relationship between the slider 3 and the block body 12. The movable pin 2 can be directly inserted into the slider cavity 32, and then the movable pin can be pushed toward the block body 12 to be inserted into the socket 121. During this process, the slider 3 can move synchronously with the movable pin 2 toward the block body 12, which can reduce the operating steps and make the pulling and closing operation more convenient.

[0056] Further, if Figure 4As shown, the rear side of the groove wall of the upper bottom plate groove 311 includes a vertical surface 3111, so that when the front protrusion 28 extends upward into the upper bottom plate groove 311, the movable pin 2 pushes the vertical surface 3111 through the front protrusion 28 to drive the slider 3 to move backward, so that the movable pin 2 can stably push the slider 3 to move backward. Specifically, as Figure 4 As shown, a small chamfered surface 3113 can be provided at the bottom of the vertical surface 3111 to soften the thrust and facilitate the front protrusion 28 to escape backward from the upper base plate groove 311 .

[0057] Further, if Figure 4 As shown, a groove guide surface 3112 is provided at the bottom of the front part of the groove wall of the upper base plate groove 311, and the groove guide surface 3112 gradually tilts downward from back to front, so that when the movable pin 2 moves forward, the front end protrusion 28 can escape from the upper base plate groove 311 by cooperating with the groove guide surface 3112.

[0058] In the process of unzipping the zipper, Figure 12 becomes Figure 11 During the state, the slider 3 moves back until the movable pin 2 enters the slider cavity 32, and the front protrusion 28 first enters the upper bottom plate groove 311, and the movable pin 2 continues to move forward. During the forward movement, the front protrusion 28 can smoothly escape from the slider cavity 32 under the guidance of the groove guide surface 3112, thereby realizing the opening of the zipper.

[0059] Further, if Figure 5 and Figure 6 As shown, the top surface of the front protrusion 28 is an irregular arc shape as a whole, with its apex located in the middle and rear position. The front side of the apex of the top surface of the front protrusion 28 is the front arc surface 281, and the rear side is the rear arc surface 282. The front arc surface 281 gradually tilts downward from back to front, and the rear arc surface 282 gradually tilts downward from front to back. In other words, the curvature of the front arc surface 281 and the rear arc surface 282 are different. Specifically, the front arc surface 281 is a generally straight beveled surface, and the rear arc surface 282 is generally a hemispherical surface, with the rear arc surface 282 having a larger curvature. The front arc surface 281 facilitates the movable pin 2 to escape from the front end of the upper base plate groove 311. Through the cooperation of the rear arc surface 282 and the vertical surface 3111, the front protrusion 28 can be clamped in the upper base plate groove 311 to limit the pull head 3 and ensure the movable pin 2's ability to push the pull head 3 backward.

[0060] Further, if Figure 4 As shown, the front end of the bottom surface of the upper bottom plate 31 of the slider is a front guide slope 312, which gradually tilts downward from front to back to facilitate the movable pin 2 to enter the slider cavity 32 from front to back. The rear end of the bottom surface of the upper bottom plate 31 of the slider is a rear guide slope 313, which gradually tilts downward from back to front to facilitate the movable pin 2 to enter the slider cavity 32 from back to front.

[0061] Further, if Figure 5As shown, a pin protrusion 23 is provided on the side of the movable pin 2. When the movable pin 2 is inserted into the socket 121 and moves into the socket 121, it moves at most until the pin protrusion 23 is abutted against the block structure 1. The pin protrusion 23 can be abutted against the block body 12, which can effectively position the movable pin 2 and the block structure 1 and prevent the movable pin 2 from excessively extending into the socket 121.

[0062] Furthermore, if Figure 5 and Figure 6 As shown, the movable pin 2 is sequentially connected from front to back, with a front pin slot 24, a rod hole 29, and a rear pin slot 25. A front protrusion 28 is slidably disposed in the front pin slot 24. A connecting rod 26, specifically a round rod, is slidably disposed in the rod hole 29. A rear protrusion 22 is slidably disposed in the rear pin slot 25. The front protrusion 28 is connected to the rear protrusion 22 via the connecting rod 26, forming a linkage structure. Under the connection of the connecting rod 26, when one of the front protrusion 28 or the rear protrusion 22 is subjected to pressure, the connecting rod 26 can drive the other downward, thereby achieving linkage. The linkage structure is connected to an elastic member 27, which imparts an upward motion to the linkage structure. Optionally, the elastic member 27 comprises a front spring and a rear spring. The front spring is disposed in the front pin slot 24, with the front protrusion 28 disposed on the front spring. The rear spring is disposed in the rear pin slot 25, with the rear protrusion 22 disposed on the rear spring.

[0063] During the process of inserting the movable pin 2 into the socket 121, when the rear end protrusion 22 enters the socket 121, the socket 121 can press down the rear end protrusion 22, so that the rear end protrusion 22 drives the front end protrusion 28 to move downward through the connecting rod 26 and disengage from the upper base plate groove 311, thereby facilitating the disengagement of the front end protrusion 28 from the upper base plate groove 311.

[0064] Furthermore, if Figure 5 and Figure 6 As shown, the middle of the top surface of the rear end protrusion 22 is the vertex, the front side of the vertex of the top surface of the rear end protrusion 22 is the front bevel 221, and the rear side is the rear bevel 222. The front bevel 221 gradually slopes downward from the back to the front, and the rear bevel 222 gradually slopes downward from the front to the back. Specifically, the rear end protrusion 22 is generally a triangular protrusion. The front bevel 221 of the rear end protrusion 22 facilitates the movable pin 2 to escape forward from the insertion hole 121, and the rear bevel 222 facilitates the movable pin 2 to enter the insertion hole 121 backward. Accordingly, as shown in FIG. Figure 7 As shown, the top front end of the jack 121 is provided with a jack extrusion surface 1211 that is inclined downward from front to back. Figure 9 In the perspective view in FIG, during the backward movement of the movable pin 2, the jack extrusion surface 1211 can gradually press down the rear end protrusion 22.

[0065] In the slider assembly of this embodiment, during the process of zipping up and closing the zipper, the movable pin 2 is inserted into the slider cavity 31, so that the front protrusion 28 is inserted upward into the groove 311 of the upper bottom plate, and then the pin 2 is pulled, and the movable pin 2 drives the slider 3 to move backward. When the rear protrusion 22 enters the socket 121 of the block body 12, the rear protrusion 22 is inserted into the socket 12 under the downward force of the socket extrusion surface 1211. At the same time, the rear protrusion 22 drives the connecting rod 26 to move downward, and the connecting rod 26 synchronously drives the front protrusion 28 to move downward. Figure 9 As shown, the front protrusion 28 loses its fixed position with the upper bottom plate groove 311, the movable pin 2 is smoothly inserted into the insertion hole 121, and the slider 3 is separated from the movable pin 2 and moves forward to close the zipper.

[0066] The slider assembly in this embodiment, during the processing, is based on the original slider assembly and, according to different types of sliders 3 and chain teeth, determines the position point in the slider cavity 32 where the movable pin 2 can drive it to slide smoothly downward. At the contact surface between the movable pin 2 and the upper bottom plate 31 of the slider, the movable pin 2 is designed with a front end protrusion 28 that can be extended and retracted up and down by elastic force, and an upper bottom plate groove 311 is designed on the bottom plate 31 of the slider to perform the positioning and limiting function between the two, to ensure that the movable pin 2 is stuck, and to provide the driving effect of the movable pin 2 to drive the slider 3 backward. In addition, on the basis of the conventional movable pin 2, the length of the movable pin 2, especially the rear end part, is extended so that when it is stuck in the slider 3, there is an excess part at the rear end of the movable pin 2. The excess part at the rear end is also designed with a rear end protrusion 22 that can be extended and retracted up and down by elastic force. The rear end protrusion 22 and the front end protrusion 28 are connected by a connecting rod 26 to form a linkage structure. At the same time, beveled surfaces are made at the front end inside the socket 121 and the entrance and exit of the bottom plate 31 on the slider to facilitate the entry and exit of the movable pin 2.

[0067] In this embodiment, through the structural design of the movable pin 2, the slider 3 and the block structure 1, it is possible to achieve that during the zipper closing and pulling process, the movable pin 2 drives the slider 3 to slide backward to the block structure 1, which can reduce the operation steps of closing and pulling the zipper. There is no need to deliberately pull the slider 3 to the bottom or align it with the block structure 1, and avoid the situation where the slider 3 cannot be pulled when the movable pin 2 is inserted and pulled when it is not aligned and attached to the block structure 1, and the chain teeth are misaligned and engaged, causing the chain to break, thereby improving the convenience and comfort of zipping.

[0068] In the second specific embodiment of the slider assembly provided by the present invention, the linkage structure of the above embodiment is not provided between the movable pin 2 and the block structure 1, but the separation of the front protrusion 28 and the upper bottom plate groove 311 is achieved by another method.

[0069] Specific reference Figures 13 to 25The bottom rear of the movable pin 2 is provided with an avoidance surface 21 that gradually tilts upward from front to back. Specifically, when processing the movable pin 2, the lower half can be cut off compared to the ordinary movable pin 2 to increase the range of motion of the movable pin 2. When force is applied to the top surface of the rear end of the movable pin 2, the front end can be tilted. The top of the hole wall of the socket 121 is provided with a lower protrusion 1213 that protrudes downward. When the movable pin 2 is inserted into the socket 121, as shown in FIG. Figure 21 As shown, the lower protrusion 1213 presses the top surface of the movable pin 2, so that the rear end of the movable pin 2 swings downward, the front end protrusion 28 moves downward and disengages from the upper bottom plate groove 311. Figure 22 Within the height range of the slider cavity 32 shown between the two horizontal dotted lines, the rear end of the movable pin 2 is subjected to force and can swing between the active states shown by the dotted line and the solid line.

[0070] In this embodiment, during the pulling and closing process, the movable pin 2 is inserted into the sliding head 3, and the movable pin 2 is stuck in the sliding head 3 through the cooperation and insertion of the upper base plate groove 311 and the front end protrusion 28, and the rear end of the movable pin 2 is in a tilted state in the sliding head cavity 32. In this state, when the movable pin 2 moves backward, the movable pin 2 has a backward force on the sliding head 3 to drive the sliding head 3 to move backward synchronously, and the part of the movable pin 2 extending out of the sliding head 3 from the rear contacts the block structure 1. Specifically, the front end of the lower protrusion 1213 is the bevel cut surface 1212 of the socket, and the bevel cut surface 1212 of the socket presses down the rear end of the movable pin 2, driving the change of the angle of the movable pin 2 in the sliding head 3, so that the front end protrusion 28 stuck in the groove 311 of the upper base plate is disengaged downward from the groove 311 of the upper base plate, and the movable pin 2 is inserted into the socket 121 of the block body 12 along the backward force.

[0071] In addition, when the zipper is opened, the movable pin 2 moves forward in the slider cavity 32. After the upper base plate groove 311 is plugged into the front end protrusion 28, the movable pin 2 continues to move forward, and the groove guide surface 3112 of the upper base plate groove 311 presses down the front arc surface 281 of the front end protrusion 28, causing the movable pin 2 to swing forward and downward and backward, so that the front end protrusion 28 disengages from the upper base plate groove 311, and then the movable pin 2 can continue to move forward to disengage from the slider cavity 32.

[0072] The slider assembly in this embodiment is mainly designed for the structure of the movable pin 2. For coordinated use, the slider 3 and the block structure 1 are also partially structurally adjusted. On the basis of the original slider assembly, the length of the movable pin 2 is extended on the basis of the conventional movable pin 2 so that it extends beyond a portion of the slider 3, and a portion of the bottom of the movable pin 2 is cut off to design a tilted style. The contact portion of the block structure 1 and the movable pin 2 is designed with a beveled surface and a convex point, so as to achieve the angle change of the movable pin 2 within the insertion range of the insertion hole 121, thereby driving the rear end of the movable pin 2 to be pressed down and the front end to be tilted, so that the front end protrusion 28 that acts as a limiter at the front end is downwardly disengaged from the limiting effect of the upper bottom plate groove 311 of the slider upper bottom plate 31, and the backward insertion force allows the movable pin 2 to be smoothly inserted into the insertion hole 121 of the block body 12.

[0073] In addition to the aforementioned slider assembly, the present invention further provides a zipper including a slider assembly. Specifically, the slider assembly may be any of the above embodiments, and the beneficial effects thereof may be referred to in conjunction with the respective embodiments. The zipper also includes two fastener strips 4, one of which is fixedly connected to the movable pin 2, and the other fastener strip 4 is fixedly connected to the block structure 1.
