Description

A slider with a lock Technical Field

[0001] The present application belongs to the field of zippers, and specifically relates to a slider with a lock pull head. Background Art

[0002] Zippers are a common switching device consisting of a zipper strap and a slider. Their simple operation—simply sliding the slider to switch the zipper strap's state—is often used to open and close items like clothing, backpacks, and tent lights. However, precisely because this simple sliding operation switches the opening state, tension between the zipper straps can cause the slider to slip, easily leading to the zipper straps opening on their own, resulting in low reliability. To improve zipper reliability, existing zippers often feature a self-locking mechanism that locks the slider once it's in place, preventing it from slipping.

[0003] In the prior art, patent document CN208096221U discloses a self-locking zipper pull, comprising a body, a cap, and a pull tab. The pull tab is characterized in that the upper end of the body has a sliding seat and a locking seat, and the ends of the cap are horizontally protruding rotating ends and sliding ends. The sliding end of the cap has a downwardly protruding spike below, which can be inserted through a strip hole and snapped into the zipper. The rotating end has an outwardly extending arcuate covering sheet above it, which covers the outer side of the rotating seat. The covering sheet is elastic, and the end of the covering sheet is connected to the body and keeps the cap close to the body. The zipper pull achieves self-locking by inserting the spike through the strip hole and snapping into the zipper. However, the zipper pull requires the pull tab to unlock the zipper pull. The connection between the pull tab and the zipper pull is relatively weak and easily damaged. When the pull tab is damaged, the zipper pull cannot be unlocked, resulting in low reliability.

[0004] Therefore, there is an urgent need for a slider with a lock puller to solve the above problems.

[0005] Summary of the Invention

[0006] In response to the problems in the existing technology, this application proposes a slider with a lock slider. The slider is slidably connected to the slider body through a slide rail. The self-locking slider is unlocked by sliding the slider, which increases the contact area between the slider and the slider body, making the connection between the slider and the slider body less prone to damage and improving the reliability of the slider.

[0007] The present application is implemented as follows: a slider with a lock, comprising a slider body, the slider body comprising upper and lower wing plates and a connecting post connecting the upper and lower wing plates, side plates being provided on the left and right side edges of the upper wing plate and / or the lower wing plate, forming a Y-shaped channel for passing a zipper chain between the upper wing plate, the lower wing plate, the connecting post and the side plates;

[0008] A slide rail and a first groove are provided at the upper end of the upper wing plate in the front-to-back direction. The first groove extends forward over the connecting column and bends downward along the connecting column to form a second groove. A lock hole is provided at the rear end of the first groove, which is connected to the Y-shaped channel.

[0009] It also includes a horse hook that is rotatably arranged in the first groove and the second groove. The horse hook is provided with a locking claw at the rear end of the rotating shaft. The locking claw passes through the lock hole and extends into the Y-shaped channel. The horse hook is located at the front end of the rotating shaft and extends along the second groove; the horse hook is also provided with an upwardly protruding stop crown at a position close to the rotating shaft; it also includes an elastic member, which is connected to the horse hook and applies continuous elastic force to the horse hook to make the locking claw of the horse hook rotate into the Y-shaped channel; a zipper chain is provided in the Y-shaped channel, and after the locking claw is rotated into the Y-shaped channel, it is engaged with the zipper chain to achieve self-locking of the slider.

[0010] The invention also includes a slider covering the upper side of the upper wing plate, which is slidably mounted on the slide rail; a front stop arm covering the second groove is provided at the front end of the slider, and when the slider slides backward, the front stop arm pushes the front end of the horse hook to rotate so that the locking claw at the rear end of the horse hook exits the Y-shaped channel; a rear stop wall is provided on the lower side of the slider, which is located behind the stop crown; when the slider slides forward, the rear stop wall pushes the stop crown so that the horse hook rotates and exits the locking claw from the Y-shaped channel. When the slider needs to be unlocked, the locking claw can be rotated out of the Y-shaped channel by driving the slider forward or backward, so that the slider can be unlocked when the zipper is opened or closed, thereby improving the convenience of the slider.

[0011] Preferably, a raised sliding base is provided on the upper side of the upper wing plate, the slide rails are provided on the left and right sides of the sliding base, and the first groove is formed concavely along the upper side of the sliding base; the lower side of the slider is provided with a slide groove that matches the slide rail, and the side walls of the slide groove extend outward along the left and right sides to the edge of the slider. The slide rails are used to guide the slider during sliding, thereby improving the smoothness of the slider's sliding. At the same time, the slide rails provided on both sides of the sliding base can prevent the slider from falling out from above the slider body, thereby improving the reliability of the connection between the slider and the slider body.

[0012] Preferably, the second groove is formed inside the connecting column, or outside the connecting column; when the second groove is formed outside the connecting column, a groove box is protruding from the front side of the connecting column, and the second groove forms an inner cavity of the groove box.

[0013] Specifically, an axis hole is provided at the upper end of the trough box, and the middle section of the horse hook is rotatably connected to the axis hole via an axis pin. The trough box is used to install the axis pin, and the horse hook is rotatably connected to the pull body via the horse hook, which simplifies the installation structure of the horse hook and improves the stability of the horse hook.

[0014] Preferably, a spring hole extending into the connecting column is provided at the bottom of the second groove. The elastic member is a compression spring installed in the spring hole, with the outer end of the compression spring abutting the front end of the horse hook. The compression spring provides the driving force for the locking claw to engage with the zipper, effectively preventing the locking claw from rotating out of the Y-shaped channel when the slider is not sliding, thereby improving the reliability of the locking claw.

[0015] Preferably, the upper end of the slider is provided with a plastic head integrally injection-molded from a different material than the slider; the upper end of the slider is provided with a glue-injection engaging portion fixed to the plastic head. The plastic head is used to protect the slider from damage caused by external impact, thereby improving the reliability of the slider.

[0016] Specifically, the plastic head is made of a flexible material, which may be silicone.

[0017] Preferably, the upper end of the slider is provided with a pull nose for mounting a pull tab. The pull tab is used to pull the slider to slide, and the slider is pulled by the pull tab, which improves the convenience of pulling the slider.

[0018] Preferably, the left and right edges of the upper wing plate extend downward to form the side plates, which are used to limit the lateral movement of the slider and prevent the slider from escaping laterally.

[0019] As an equivalent alternative, the left and right edges of the lower wing panel extend upward to form the side panels, which continue to extend upward to the height of the upper wing panel and extend inward to form flap panels. The gap between the flap panels and the upper wing panel forms a Y-shaped notch corresponding to the Y-shaped channel. The flap panels are used to conceal the slider, allowing it to be hidden inside the zipper string, improving the aesthetics.

[0020] Preferably, the upper end of the upper wing plate is further provided with a limiting boss, and the lower end of the slider is provided with a limiting groove. The limiting groove is adapted to the limiting boss, and when the slider slides forward and backward, the limiting boss intermittently abuts against the limiting groove. The limiting groove is used to limit the forward and backward sliding stroke of the slider, preventing the slider from sliding off the guide rail, thereby improving the reliability of the slider.

[0021] Specifically, one end of the limiting groove is in communication with the outside world, and the other end is provided with a limiting surface. A gap exists between the limiting surface and the limiting boss. When the slider slides backward a distance corresponding to the gap, the limiting surface abuts the limiting boss. One end of the limiting groove is in communication with the outside world, allowing the limiting boss to slide into the limiting groove from the end of the limiting groove that is in communication with the outside world, thereby improving the convenience of installing the slider.

[0022] Beneficial effects of this application:

[0023] The present application proposes a slider with a lock slider, which is slidably connected to the slider body through a slide rail. The self-locking slider is unlocked by sliding the slider, which increases the contact area between the slider and the slider body, makes the connection between the slider and the slider body less prone to damage, and improves the reliability of the slider; at the same time, the slider can slide forward or backward to rotate the locking claw out of the Y-shaped channel, so that the slider can be unlocked when the zipper is opened or closed, thereby improving the convenience of the slider.

A Y-shaped channel for passing the zipper chain is formed between the upper wing panel 11, the lower wing panel 12, the connecting column 19 and the side panels 13.

[0036] A slide rail 15 and a first groove 16 are provided at the upper end of the upper wing plate 11 along the front-to-back direction. The first groove 16 extends forward over a connecting post 19 and bends downward along the connecting post 19 to form a second groove 17. A lock hole 18 is provided at the rear end of the first groove 16, which communicates with the Y-shaped channel.

[0037] In this embodiment, a raised sliding base 14 is provided on the upper side of the upper wing plate 11. Slide rails 15 are provided on the left and right sides of the sliding base 14. A first groove 16 is formed concavely along the upper side of the sliding base 14. A sliding groove matching the slide rails 15 is provided on the lower side of the slider 2. The sidewalls of the sliding groove extend outward along the left and right sides to the edge of the slider 2. The slide rails 15 guide the slider 2 during sliding, improving its smoothness. Furthermore, the slide rails 15 provided on both sides of the sliding base 14 prevent the slider 2 from dislodging from above the slider body 1, thereby improving the reliability of the connection between the slider 2 and the slider body 1.

[0038] It also includes a horse hook 3 that is rotatably arranged in the first groove 16 and the second groove 17. The horse hook 3 is provided with a locking claw 31 at the rear end of the rotating shaft. The locking claw 31 passes through the locking hole 18 and extends into the Y-shaped channel. The horse hook 3 is located at the front end of the rotating shaft and extends along the second groove 17; the horse hook 3 is also provided with an upwardly protruding stop crown 32 at a position close to the rotating shaft; it also includes an elastic member, which is connected to the horse hook 3 and applies continuous elastic force to the horse hook 3 to make the locking claw 31 of the horse hook 3 rotate into the Y-shaped channel; a zipper chain is provided in the Y-shaped channel, and after the locking claw 31 is rotated into the Y-shaped channel, it is engaged with the zipper chain to achieve self-locking of the slider.

[0039] In this embodiment, the second groove 17 is formed inside the connecting column 19, or formed outside the connecting column 19; when the second groove 17 is formed outside the connecting column 19, a groove box is protruded from the front side of the connecting column 19, and the second groove 17 forms an inner cavity of the groove box.
