[0043] In a specific embodiment, the slider provided by the present invention includes a slider body 1 capable of engaging with a chain and a hook 4 provided on the slider body 1, wherein the hook 4 includes a first end 41 capable of locking with a chain tooth and a second end 42 embedded in the interior of the slider body 1 for positioning; and further includes:

[0044] The sliding cap 2 is slidably connected to the slider body 1, and the sliding cap 2 includes a supporting portion 22 that can contact and support the horse hook 4. When the sliding cap 2 slides relative to the slider body 1, the supporting portion 22 contacts the horse hook 4 and can drive the horse hook 4 to move toward or away from the chain to achieve locking or unlocking.

[0045] The two sides of the slider body 1 can be engaged with the chain teeth of the chain. The specific engagement structure can be referred to the prior art and will not be described in detail here. The first end 41 and the second end 42 of the horse hook 4 are both embedded in the slider body 1, the first end 41 is locked with the chain teeth, and the second end 42 is fixed with the slider body 1 to limit the movement of the horse hook 4 in the slider body 1.

[0046] The sliding cap 2 is slidably connected to the slider body 1, such as by a slide rail slider 21 mechanism. The support portion 22 can contact and support the horse hook 4, and the support portion 22 can be set as a support rod, or a support protrusion set on the end wall of the sliding cap 2. Preferably, the support portion 22 is set below the horse hook 4 and contacts and supports its lower surface. It can be understood that the horse hook 4 is fixed relative to the slider body 1. When the sliding cap 2 slides relative to the slider body 1, it also slides relative to the horse hook 4. The sliding direction of the sliding cap 2 is preferably parallel to the center line direction of the slider body 1. More preferably, it slides along the second end 42 of the horse hook 4 to the first end 41. The position and sliding direction of the sliding cap 2 can be set as needed.

[0047] The sliding cap 2 is preferably provided integrally with the support portion 22 to facilitate production and processing. Alternatively, in another embodiment, the sliding cap 2 and the support portion 22 can also be fixed by snapping or other means. When in use, the sliding cap 2 is slidably connected to the slider body 1. In the initial position, the horse hook 4 and the chain teeth are in a locked state. When the sliding cap 2 slides relative to the slider body 1, the support portion 22 can contact the horse hook 4, and as the sliding cap 2 slides, the horse hook 4 moves away from the chain so that the horse hook 4 is disengaged and unlocked from the chain teeth; when the horse hook 4 needs to be locked with the chain teeth, the sliding cap 2 can be pushed to move back to the initial position to complete the locking.

[0048] Compared with the prior art, the slider provided by the present invention has the following technical effects:

[0049] First, there is no need to set a pull tab, and the sliding cap 2 can drive the horse hook 4 to move towards or away from the chain to achieve locking or unlocking. When in use, you only need to slide the sliding cap 2 to release the locking force. Its structure is simple and provides a new type of slider structure; second, it solves the problem of paint falling off after the slider is painted, and the problem that the pull tab is easy to shake during movement and directly contacts the skin and causes discomfort.

[0050] Specifically, the horse hook 4 also includes a concave curved surface 43 for connecting the first end 41 and the second end 42;

[0051] The support portion 22 is arranged below the horse hook 4 and can contact the concave curved surface 43. The support portion 22 includes an outer convex curved surface that smoothly transitions from front to back along the sliding direction. When the sliding cap 2 slides relative to the slider body 1, the outer convex curved surface contacts the inner concave curved surface 43 and pushes the inner concave curved surface 43 upward.

[0052] During the sliding process, the support part 22 slides from the highest point of the concave curved surface 43 to the lowest point, and the concave curved surface 43 makes the sliding process smoother. At the same time, in order to ensure that the upward lifting distance of the horse hook 4 can be separated from the chain teeth, the support part 22 is provided with a convex curved surface. During the sliding process, the lowest point of the convex curved surface contacts the highest point of the concave curved surface 43 and gradually slides to the lowest point of the concave curved surface 43. The upward lifting distance of the horse hook 4 is the distance between the highest point and the lowest point of the convex curved surface.

[0053] In another embodiment, the shape of the horse hook 4 can be set as needed. During the sliding contact with the surface of the horse hook 4, the maximum upward movement distance of the horse hook 4 is set by the distance between the highest point and the lowest point of the convex curved surface of the support part 22. At the same time, the shape of the support part 22 can also be set as needed, as long as the same technical effect can be achieved.

[0054] Furthermore, the sliding cap 2 is arranged above the horse hook 4 and is provided with a clearance cavity 23 for making way for the horse hook 4 when sliding. The support part 22 is arranged below the clearance cavity 23 and forms a fitting opening with the inner wall of the clearance cavity 23 for fitting with the horse hook 4.

[0055] During installation, the second end 42 of the horse hook 4 extends through the sleeve opening to the clearance cavity 23, and the first end 41 and the second end 42 of the horse hook 4 sleeved with the support portion 22 are respectively positioned and installed with the slider body 1. During the sliding process of the sliding cap 2, the clearance cavity 23 moves relative to the horse hook 4 from the second end 42 to the first end 41, and the horse hook 4 is made to make way through the clearance cavity 23 to prevent the sliding cap 2 from colliding with the horse hook 4 during the sliding process. In addition, the second end 42 of the horse hook 4 is covered by the clearance cavity 23 to prevent rainwater and the like from eroding the inside of the horse hook 4 and the slider body 1.

[0056] The shape of the give-way cavity 23 can be set according to the shape of the second end 42 of the horse hook 4. The give-way cavity 23 is an open cavity with an opening at the lower end, and it can be fitted with the horse hook 4 only through the fitting opening. The support part 22 and the inner wall of the give-way cavity 23 form the fitting opening. The width of the fitting opening is set according to the width of the horse hook 4. It can be set to a rectangle or other shapes as needed.

[0057] In one embodiment, in order to realize the sliding connection between the slider body 1 and the sliding cap 2, a slide groove 11 is provided on the slider body 1 and is arranged parallel to the length direction of the horse hook 4, and a slider 21 is provided on the sliding cap 2 to cooperate with the slide groove 11, wherein the slide groove 11 can be arranged as a concave groove slide groove 11 concave in the surface of the slider body 1, and the slider 21 can be arranged on the bottom wall of the support portion 22 accordingly. When the slider 21 is at the first end of the slide groove on the slide groove 11, the horse hook 4 and the chain are in a locked state, and when the slider 21 moves on the slide groove 11 in a direction away from the first end of the slide groove to the second end of the slide groove, the support portion 22 contacts the horse hook 4 and drives the horse hook 4 to move in a direction away from the chain to realize unlocking.

[0058] Preferably, in order to limit the maximum sliding distance of the sliding cap 2, the device further comprises:

[0059] The limiting cap 3 is arranged on the slider body 1 at one side of the second end 42 near the slide groove 11 to limit the maximum sliding distance of the sliding cap 2. The sliding of the sliding cap 2 is limited by the limiting cap 3. The limiting cap 3 can be abutted against the sliding cap 2 to prevent the sliding of the sliding cap 2. In another embodiment, the maximum sliding distance of the sliding cap 2 can be directly limited by setting the length of the slide groove 11.
