Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to an anti-fouling zipper head. Background Art

[0002] A zipper is a chain-shaped metal or plastic product that can be opened and closed. It consists of teeth, a slider, and upper and lower stops. It is now widely used in clothing, bags, tents, and other items. Its ease of opening and closing, durability, and durability make it one of the ten most convenient inventions of modern times. The zipper pull, also known as the slider or zipper teeth, is primarily used to adjust the zipper's opening and closing. The slider slides along the ridge of the puller to control the zipper's opening and closing.

[0003] To facilitate the replacement of pull tabs, existing zipper pulls are equipped with a sliding block for easy pull tab installation, and a chute for mounting the sliding block. The chute is equipped with a spring, allowing the sliding block to slide, providing a mounting channel for the pull tab to fit into the zipper pull. After manufacturing, the zipper pull needs to be plated. The chute where the spring and sliding block are mounted is prone to accumulating electroplating wastewater. This highly acidic wastewater can corrode the internal spring, affecting the zipper pull's aesthetics and lifespan. Over time, it can cause dirt to accumulate. Furthermore, during laundry, wastewater can easily remain in the chute, corroding the interior and affecting the smooth sliding of the slider within the rail, making it prone to getting stuck.

[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0025] like Figures 1-6 As shown, a dirt-proof zipper head includes an upper plate 1, a guide post 2, a lower plate 3, and a pull nose 4. The guide post 2 is fixed between the upper plate 1 and the lower plate 3, and the pull nose 4 is fixed on the upper surface of the upper plate 1; a chute 11 is provided on the upper plate 1, and a slider 5 is slidably fitted in the chute 11. A drainage groove 12 is provided on the surface of the upper plate 1 close to the lower plate 3, and the drainage groove 12 is connected to the chute 11 to discharge the sewage in the chute 11.

[0026] By adopting the above technical solution, a drainage groove 12 connected to the chute 11 is opened on the upper plate 1, so that after the zipper head is electroplated, the electroplating wastewater in the chute 11 is automatically discharged, avoiding the internal accumulation of wastewater and causing corrosion of internal components. In addition, the water in the chute 11 can be discharged in time during cleaning during use, preventing rust and dirt accumulation inside the chute 11, thereby improving the sliding smoothness of the slider 5.

[0027] A connector post 41 extending toward the upper plate 1 is provided at the end of the pull nose 4 away from the guide post 2. A first gap is defined between the connector post 41 and the upper plate 1. A limiting post 51 is fixedly connected to the slider 5. The limiting post 51 is located in the first gap and blocks the first gap between the connector post 41 and the upper plate 1, thereby limiting the pull tab 7 in the installation cavity formed between the pull nose 4 and the upper plate 1. By providing the connector post 41 and the limiting post 51, the zipper pull tab 7 can be confined between the pull nose 4 and the upper plate 1. By moving the slider 5, the limiting post 51 and the connector post 41 can be offset, thereby allowing the pull tab 7 to be removed and easily replaced. A guide bevel 52 is provided on the side of the limiting post 51 away from the guide post 2. When installing the pull tab 7, the slider 5 moves a certain distance, allowing the pull tab 7 to squeeze the guide bevel 52 and slide into the inner side of the pull nose 4.

[0028] The drainage groove 12 is arranged along the sliding direction of the slider 5, and its width is smaller than that of the chute 11. Thus, the drainage groove 12 splits the chute 11 along its length, near the lower plate 3, allowing dirt in the chute 11 to flow out more easily. The drainage groove 12 is narrower than the chute 11, thus guiding the slider 5 and preventing it from falling out of the chute 11. The chute 11 is arranged along the centerline of the upper plate 1, and the end of the chute 11 away from the guide post 2 is open. During installation, the slider 5 and spring 6 are pushed into the chute 11 from the open end, and then the stopper 13 is riveted, facilitating installation of the slider 5 and spring 6.

[0029] The slide 11 has a mounting groove 15 at one end thereof, which is close to the guide post 2. A spring 6 is disposed in the mounting groove 15. A stopper 13 is fixedly connected to the upper plate 1. A stepped surface 53 is disposed on the slider 5. The stopper 13 is located on the side of the stepped surface 53 away from the pull nose 4. The spring 6 abuts against the end of the slider 5 to push the slider 5 out so that the stepped surface 53 of the slider 5 abuts against the stopper 13. When the stepped surface 53 of the slider 5 abuts against the stopper 13, the limiting post 51 is located between the connector post 41 and the upper plate 1. The stopper 13 limits the position of the slider 5, and the elastic force provided by the spring 6 enables the limiting post 51 to be in a relative position to the connector post 41 in a natural state, thereby blocking the gap between the connector post 41 and the upper plate 1 and preventing the pull tab 7 from falling off.

[0030] The upper plate 1 is provided with an escape groove 14 on the side away from the lower plate 3, the escape groove 14 is connected to the slide groove 11, and the limit column 51 is located in the escape groove 14. The escape groove 14 is provided to avoid the limit column 51, providing a movement space for the limit column 51, and facilitating the movement of the limit column 51.

[0031] The parts not involved in this technical solution can be implemented using existing technologies.

[0032] The above shows and describes the basic principles, main features, and characteristics of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
