Abstract
Description
A hook pull tab with interchangeable decorations Technical Field
[0001] This utility model relates to the field of pull tab technology, specifically to a hook pull tab with replaceable decoration. Background Technology
[0002] As a simple, stable, and reliable connector, zippers are widely used in various industries such as garment processing and bag production. A zipper generally includes teeth, a slider, a top stop, a bottom stop, and a pull tab for pulling the slider.
[0003] Most zipper pulls currently available often have decorative elements installed on them for aesthetic purposes. To prevent these decorations from falling off during later use, manufacturers use rivets to secure them. While this method is relatively secure and prevents the decorations from detaching later, it also means that if the user needs to replace the decorations later, the rivets must be removed, which is difficult and can easily damage the pull and the decorations, causing considerable inconvenience to the user. Utility Model Content
[0004] The purpose of this utility model is to provide a replaceable decorative hook and pull tab to solve the technical problems mentioned in the background art.
[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0006] A hook-and-loop fastener with interchangeable decorations, comprising a fastener body;
[0007] The bottom of the pull tab body is provided with a hook part, and one side of the bottom of the pull tab body is provided with an inclined surface that connects with the hook part. An movable groove is provided on the inner side of the inclined surface, and a binding rod is movably arranged inside the movable groove. A limiting slide groove is provided on the side of the binding rod near the inclined surface. A sliding seat is slidably arranged inside the limiting slide groove. An insert plate is provided at the bottom of the sliding seat, and a number of sets of spaced limiting protrusions are provided on one side of the insert plate.
[0008] The inner wall of the hook body is provided with a fixing seat that matches the insert plate. Several sets of blocking blocks are arranged at intervals on the side of the fixing seat near the limiting protrusion, and the blocking blocks and the limiting protrusion are distributed alternately.
[0009] As a further embodiment of this utility model: the hook body and the end face of the restraining rod that are close to each other are symmetrically provided with stepped grooves that engage with each other, and the fixed seat is L-shaped.
[0010] As a further embodiment of this utility model: the limiting protrusion and the blocking block are hemispherical in shape and made of elastic material.
[0011] As a further embodiment of this utility model: the bottom of the insert plate is provided with a plug shaft, and the bottom wall of the fixing seat is provided with a slot that matches the plug shaft.
[0012] As a further embodiment of this utility model, the pull tab body is provided with a fixing member for fixing the end of the binding rod away from the hook body.
[0013] As a further embodiment of this utility model, a pull head groove is provided on the top of the pull tab body.
[0014] The beneficial effects of this utility model are:
[0015] This invention provides a good limit for the rotatable restraint rod through the insertion of the insert plate and the fixing seat. The restraint rod and the fixing seat are staggered on opposite sides, with limit protrusions and blocking blocks. When the insert plate is inserted into the fixing seat, the limit protrusions and blocking blocks engage with each other, further enhancing the fixing effect of the fixing seat on the insert plate. This ensures that the restraint rod will not rotate during use, greatly reducing the probability of the decoration falling off. When it is necessary to replace the decoration, simply pull the sliding seat upwards to disengage the insert plate from the fixing seat. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] As shown in Figures 1-3, a hook and pull tab with replaceable decoration includes a pull tab body 1;
[0023] The bottom of the pull tab body 1 is provided with a hook part 2. A slope 3 connecting to the hook part 2 is provided on one side of the bottom of the pull tab body 1. A movable groove 4 is provided on the inner side of the slope 3. A restraining rod 5 is movably installed inside the movable groove 4. A stepped groove that engages with each other is symmetrically provided on the end faces of the hook part 2 and the restraining rod 5 that are close to each other. A limiting slide groove 6 is provided on the side of the restraining rod 5 near the slope 3. A sliding seat 7 is slidably installed inside the limiting slide groove 6. An insert plate 8 is provided at the bottom of the sliding seat 7. One side of the pull tab has several sets of spaced-apart limiting protrusions 10. The limiting protrusions 10 and the blocking blocks 13 are hemispherical in shape and made of elastic material. The inner wall of the hook body 2 is provided with a fixing seat 11 that matches the insert plate 8. The fixing seat 11 is L-shaped. Several sets of blocking blocks 13 are spaced-apart on the side of the fixing seat 11 near the limiting protrusions 10, and the blocking blocks 13 and the limiting protrusions 10 are staggered. The pull tab body 1, the hook body 2 and the binding rod 5 constitute the main body of the pull tab. The body ensures the normal use of the pull tab. The decoration can be riveted onto the hook body 2. When the decoration needs to be replaced, the worker pulls the sliding seat 7 upward, causing the insert plate 8 to disengage from the fixed seat 11, thereby releasing the fixation of the restraining rod 5. The worker can then press the restraining rod 5 inward, creating a gap between the restraining rod 5 and the hook body 2, allowing the decoration to be replaced. After replacement, the worker moves the restraining rod 5 back to its original position and presses the sliding seat 7 downward, causing the insert plate 8 to re-insert into the L-shaped fixed seat 11, forming a stable limit on the restraining rod 5. The limiting protrusions 10 and blocking blocks 13, which are staggered on the side of the restraining rod 5 and the fixed seat 11 that are close to each other, can form a misaligned engagement when the insert plate 8 is inserted into the fixed seat 11, thereby further improving the fixing effect of the fixed seat 11 on the insert plate 8, ensuring that the restraining rod 5 will not rotate during use, and greatly reducing the probability of the decoration falling off.
[0024] In this embodiment, specifically, the bottom of the insert plate 8 is provided with a plug shaft 9, and the bottom wall of the fixing seat 11 is provided with a slot 12 that matches the plug shaft 9. When the insert plate 8 is inserted into the interior of the fixing seat 11, the plug shaft 9 at its end will also be inserted into the slot 12 opened on the fixing seat 11, which increases the degree of fit between the insert plate 8 and the fixing seat 11 and further prevents the insert plate 8 from shifting in the fixing seat 11.
[0025] In this embodiment, specifically, the pull tab body 1 is provided with a fixing member 14 for fixing the end of the binding rod 5 away from the hook body 2. The fixing member 14 forms a stable limit on the binding rod 5, while ensuring that the binding rod 5 can rotate smoothly to the inside of the pull tab body 1.
[0026] In this embodiment, specifically, a pull head groove 15 is provided on the top of the pull tab body 1 for assembling the pull tab body 1 and the pull head together.
[0027] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
