Detailed implementation mode

[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0027] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0028] A hardware pull head with good wear resistance, including a pull head body 1, the pull head body 1 is composed of a base 2 and a cover 3, a fixed ring 4 is rotatably connected to the top of the cover 3, and the inside of the front end of the base 2 is fixedly connected to the fixed ring 4 through a fixing mechanism 5. A wear-resistant lining 6 is clamped inside the fixed ring 4, a connecting ring 7 is sleeved inside the fixed ring 4, a buffer mechanism 8 is installed inside the connecting ring 7, and one end of the connecting ring 7 away from the fixed ring 4 is fixedly connected to a pull handle 9.

[0029] First of all, wear-resistant coatings are applied to the inner sides of the base 2, the cover 3 and the connecting ring 7. The wear-resistant coating is chromium tungsten alloy or cobalt tungsten alloy. The wear-resistant coatings on the inner sides of the base 2 and the cover 3 can improve the wear resistance of the inner sides, reduce the wear with the zipper, and thus improve the service life of the pull head body 1. Since the connecting ring 7 is often worn out quickly due to frequent activities, the wear on its inner side is reduced by applying a wear-resistant coating on the inner side, thereby improving the service life of the connecting ring 7.

[0030] Further, the fixing mechanism 5 includes a button 501 slidably connected to the inner top end of the base 2. A limit ring 502 is fixedly connected to the top end outside the button 501. A stop block 503 is fixedly connected to the bottom end of the button 501. The bottom end of the stop block 503 is fixedly connected to the inside of the base 2 through a first spring 504. On the left and right sides of the stop block 503 inside the base 2, there are two mating blocks 505 slidably connected. Both groups of mating blocks 505 are slidably connected to the base 2 through slide columns 506. A second spring 507 is sleeved on the outside of both groups of slide columns 506. One end of both groups of slide columns 506 located outside the base 2 is fixedly connected with a clamping block 508. A clamping slot 509 is opened at the position corresponding to the clamping block 508 inside the fixing ring 4. Under the action of the first spring 504, the stop block 503 is continuously pushed upward, and at the same time, the lifting height of the button 501 is limited by the limit ring 502, so that the top end of the button 501 is exposed outside the fixing ring 4. Under the action of the second spring 507, the clamping block 508 is pushed into the inner side of the clamping slot 509, thereby fixing between the base 2 and the fixing ring 4, enabling the pull head body 1 to be used normally as a whole. When the teeth of the zipper become loose, the button 501 can be pressed to move the stop block 503 downward. At this time, the mating blocks 505 are not blocked and are pushed out by the second spring 507, so that the two clamping blocks 508 retract into the inside of the base 2, thereby releasing the fixing of the fixing ring 4, enabling the cover 3 and the base 2 to be opened. At this time, the zipper can be engaged and then the cover 3 and the base 2 can be closed again for fixing, so that the zipper can be engaged without pulling the pull head body 1, avoiding the risk of damage. At the same time, when the connecting ring 7 is broken, the fixing of the fixing ring 4 can also be released in the same way. The fixing ring 4 can be turned over to replace the connecting ring 7 and the rear pull handle 9, thereby greatly improving the convenience of using the pull head body 1.

[0031] Then, the upper and lower ends of both groups of mating blocks 505 are slidably connected to the base 2 through limit sliding grooves 510. The two ends of the second spring 507 are respectively fixedly connected to the base 2 and the mating blocks 505. The moving distance of the mating blocks 505 is limited by the limit sliding grooves 510, and the mating blocks 505 are driven to move by the second spring 507.

[0032] Among them, both the front and rear ends of the wear-resistant inner lining 6 are fixedly connected with insertion blocks 601. Both groups of insertion blocks 601 are inserted into the fixing ring 4 through insertion slots 602. The wear-resistant inner lining 6 is made of nylon material. The connection between the connecting ring 7 and the fixing ring 4 is in an active state. The insertion blocks 601 are inserted into the inner side of the insertion slots 602 to fix the wear-resistant inner lining 6. When pulling the pull handle 9, it is protected by the wear-resistant nylon inner lining 6, thereby preventing the inner side of the fixing ring 4 from being directly worn and broken. At the same time, after the wear-resistant inner lining 6 is worn, it can also be pulled out for replacement, further improving the service life of the pull head body 1.

[0033] Secondly, the connecting ring 7 is composed of a connecting half-ring 701, an intermediate section 702 and a movable half-ring 703. The intermediate section 702 is located between the connecting half-ring 701 and the movable half-ring 703, and the buffer mechanism 8 is installed inside the intermediate section 702. The buffer mechanism 8 includes a third spring 801 movably installed inside the intermediate section 702. Both ends of the connecting half-ring 701 and the movable half-ring 703 are fixedly connected to the third spring 801 through connecting heads 802. When the pull handle 9 is pulled, the connecting ring 7 will be directly affected by the pulling force. The third spring 801 is stretched and elongated under the influence of the pulling force, causing the separation between the connecting half-ring 701, the intermediate section 702 and the movable half-ring 703. The stretching and resetting of the third spring 801 are used to buffer the pulling force, thereby increasing the service life of the connecting ring 7.

[0034] Finally, a LOGO area 901 is provided at the front end of the outer side of the pull handle 9. The LOGO area 901 can be printed with the LOGO of the merchant for identification and anti-counterfeiting. The rear end of the outer side of the pull handle 9 is fixedly connected with an anti-slip convex block 902. The anti-slip convex block 902 is made of rubber material, and a plurality of groups of anti-slip lines are provided on the outer side of the anti-slip convex block 902. When the pull handle 9 is pulled, the anti-slip convex block 902 is pinched by hand, and the anti-slip convex block 902 made of rubber material and the anti-slip lines provided on its outer side are used to prevent the hand from slipping off when the pull handle 9 is pulled.

[0035] In this embodiment, the implementation scenario is specifically as follows: The wear-resistant coatings on the inner sides of the base 2, the cover 3, and the connecting ring 7 can improve the wear-resistant effect on the inner sides, reduce the wear on their inner sides, thereby increasing the service life of the slider body 1 and the connecting ring 7. When the slider body 1 is in use, the fixing mechanism 5 is used to fix between the base 2 and the fixing ring 4, enabling the slider body 1 to be used normally as a whole. When the teeth of the zipper become loose, the fixing of the fixing ring 4 can be released through the fixing mechanism 5, allowing the cover 3 and the base 2 to be opened. At this time, the zipper can be meshed and then the cover 3 and the base 2 can be closed again for fixing, so that the zipper can be meshed without pulling the slider body 1, avoiding the risk of damage. At the same time, when the connecting ring 7 breaks, the fixing of the fixing ring 4 can also be released in the same way, and the fixing ring 4 can be turned over to replace the connecting ring 7 and the pull handle 9 at the rear end. When pulling the pull handle 9, it is protected by the wear-resistant inner lining 6 of nylon, thus preventing the inner side of the fixing ring 4 from being directly worn and broken. At the same time, the wear-resistant inner lining 6 can also be taken out for replacement after wear, further increasing the service life of the slider body 1. When pulling the pull handle 9, the connecting ring 7 will be directly affected by the pulling force. The third spring 801 is stretched and elongated under the influence of the pulling force, causing the connecting half-ring 701, the middle section 702, and the movable half-ring 703 to separate. The stretching and resetting of the third spring 801 are used to buffer the pulling force, thereby increasing the service life of the connecting ring 7. The entire operation process is simple and convenient. Compared with the existing hardware sliders, the present utility model can improve the overall wear-resistant effect of the hardware slider through design, thereby increasing the overall service life and greatly improving the convenience of use.

[0036] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
