Abstract
Description
Technical Field
[0001] This utility model relates to the field of buckles, and more particularly to durable quick-release buckles. Background Technology
[0002] As a common connecting and fixing structure, snap-fit is widely used in industrial design, electronic products, automobile manufacturing, furniture assembly and other fields. Traditional snap-fit designs mostly rely on metal or plastic materials to achieve quick assembly and disassembly of parts through elastic deformation. However, after long-term use, the connection is prone to failure due to fatigue aging.
[0003] In existing technologies, common quick-release clips work by precisely engaging a female clip to securely connect and fix two components. However, in practical use, the female clip typically needs a certain degree of flexibility to smoothly engage and disengage with the female clip during installation and removal. This requirement for flexibility sacrifices the strength of the female clip to some extent. Under prolonged use or frequent disassembly, the female clip inevitably undergoes repeated deformation. Each engagement and disengagement applies stress to the female clip, causing minor changes in its internal structure. Over time, these minor changes accumulate, eventually significantly reducing the strength of the female clip. When the strength of the female clip decreases to a certain level, it can no longer withstand the stress under normal operating conditions, leading to breakage, deformation, and other failures. These failures not only affect the normal use of equipment or products but may also cause a series of safety issues. Therefore, it is necessary to develop durable quick-release clips to solve these problems. Utility Model Content
[0004] In order to overcome the problem that relying on the deformation of the sub-clamp itself for disassembly and snapping can gradually reduce the strength of the sub-clamp itself during long-term use, eventually leading to an unstable snapping or even breakage of the sub-clamp.
[0005] The technical solution of this utility model is as follows: a durable quick-release buckle, including a bottom shell of the buckle and a first pressing button. A top shell of the buckle is provided outside the bottom shell of the buckle. A female buckle body is provided outside the bottom shell of the buckle for engaging. The first pressing button is slidably connected inside the bottom shell of the buckle. A first connecting rod is fixedly connected to the first pressing button. A first fixing plate is fixedly connected inside the bottom shell of the buckle. A third fixing plate is fixedly connected inside the bottom shell of the buckle. A first guide rod is fixedly connected between the first fixing plate and the third fixing plate. A first sliding block is slidably connected to the first guide rod. A second spring is fixedly connected between the first sliding block and the third fixing plate. A first insertion rod is snapped into the inside of the first connecting rod. A fastening bolt is threadedly connected between the first connecting rod and the first insertion rod. A locking rod is fixedly connected to the first insertion rod. The locking rod is snapped into the inside of the female buckle body.
[0006] Preferably, the bottom shell of the clasp has a groove at the position opposite to the first pressing button, and the first pressing button is slidably connected inside the groove.
[0007] Preferably, the first sliding block has a through groove inside, and the first plug rod passes through the through groove and is snapped into the inside of the first connecting rod.
[0008] Preferably, a second fixing plate is fixedly connected inside the first pressing button, and a first spring is fixedly connected between the second fixing plate and the first pressing button. A second pressing button is slidably connected inside the bottom shell of the sub-button. A second connecting rod is fixedly connected to the bottom of the second pressing button, and a first linkage rod is fixedly connected to the second connecting rod. A second slider is slidably connected inside the first pressing button, and the first linkage rod is slidably connected inside the second slider. A fourth fixing plate is fixedly connected inside the first pressing button, and a third spring is fixedly connected between the fourth fixing plate and the second slider. A snap-fit rod is fixedly connected to the second slider. A connecting block is fixedly connected to the bottom of the top shell of the sub-button, and the snap-fit rod is snap-fitted into the inside of the connecting block.
[0009] Preferably, the bottom shell of the clasp has a slide rail at the position opposite to the second button, and the second button is slidably connected inside the slide rail.
[0010] Preferably, the second slider has a groove at the relative position of the first linkage rod, and the first linkage rod is slidably connected inside the groove.
[0011] Preferably, the connecting block has a slot at the relative position of the locking rod, and the locking rod is locked inside the slot.
[0012] The beneficial effects of this utility model are:
[0013] 1. Compared to the traditional method of deforming the clamping rod by squeezing, the clamping rod is moved by sliding the first sliding block, which avoids bending the clamping rod under force. The clamping rod is fixed by connecting the first plug rod with fastening bolts. If the clamping rod is damaged in the future, it can be replaced separately. This avoids the problem of relying on the deformation of the sub-clamp itself for disassembly and snapping, which will gradually reduce the strength of the sub-clamp itself during long-term use, eventually leading to problems such as insecure snapping or even breakage of the sub-clamp.
[0014] 2. Compared to the traditional bolt fixing method, the top shell of the device is fixed by snapping the connecting rod with the connecting block. During subsequent disassembly, pressing the second button moves the snapping rod to release the restriction of the connecting block. The disassembly process is simple and quick, and users can more conveniently inspect or maintain the equipment. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment of a durable quick-release buckle, including a bottom shell 1 and a first pressing button 21. A top shell 4 is provided on the outside of the bottom shell 1, and a female buckle body 5 is provided on the outside of the bottom shell 1 for engagement. The first pressing button 21 is slidably connected inside the bottom shell 1, and a first connecting rod 22 is fixedly connected to the first pressing button 21. A first fixing plate 23 and a third fixing plate 211 are fixedly connected inside the bottom shell 1. A first guide rod 24 is fixedly connected between the first fixing plate 23 and the third fixing plate 211. A first sliding block 25 is slidably connected to the first guide rod 24, and a second spring 25 is fixedly connected between the first sliding block 25 and the third fixing plate 211. 12. The first connecting rod 22 is internally connected to the first insertion rod 26. The first connecting rod 22 and the first insertion rod 26 are internally threaded together by a fastening bolt 27. A locking rod 28 is fixedly connected to the first insertion rod 26. The locking rod 28 is locked inside the female buckle body 5. In use, by pressing the first pressing button 21, the first pressing button 21 moves, which drives the first sliding block 25 to slide outside the first guide rod 24 through the first connecting rod 22. This causes the locking rod 28 to slide inward, so that the locking rod 28 is inserted into the female buckle body 5. After releasing the first pressing button 21, the second spring 212 provides a pushing force to the first sliding block 25, pushing the locking rod 28 and the first sliding block 25 to slide outward, thereby locking the locking rod 28 with the female buckle body 5. This completes the connection between the female and male buckles. If the locking rod 28 is damaged, loosen the fastening bolt 27 to release the restriction on the first insertion rod 26, then remove the locking rod 28 for replacement. After replacement, align the first insertion rod 26 with the slot of the first connecting rod 22, ensuring the threaded hole of the first insertion rod 26 aligns with the threaded hole of the first connecting rod 22. Then, thread the fastening bolt 27 into the slot, completing the replacement of the locking rod 28. The female buckle base 1 has a sliding groove at the relative position of the first pressing button 21. The first pressing button 21 is slidably connected inside the sliding groove, restricting the sliding of the first pressing button 21 and preventing it from detaching from the female buckle base 1 during sliding, thus affecting the subsequent movement of the locking rod 28. The moving block 25 has a through groove inside, through which the first insertion rod 26 passes and engages with the inside of the first connecting rod 22. When installing or replacing the locking rod 28, the through groove restricts the position of the first insertion rod 26 to prevent it from shifting from the locking rod 28 and affecting the engagement of the subsequent female buckle body 5. The first pressing button 21 has a second fixing plate 29 fixedly connected inside, and a first spring 210 is fixedly connected between the second fixing plate 29 and the first pressing button 21. The bottom shell 1 of the female buckle has a second pressing button 213 slidably connected inside, and a second connecting rod 214 is fixedly connected to the bottom of the second pressing button 213. A first linkage rod 215 is fixedly connected to the second connecting rod 214, and a second slider 216 is slidably connected inside the first pressing button 21.The first linkage rod 215 is slidably connected inside the second slider 216. A fourth fixing plate 217 is fixedly connected inside the first pressing button 21. A third spring 218 is fixedly connected between the fourth fixing plate 217 and the second slider 216. A locking rod 219 is fixedly connected to the second slider 216. A connecting block 220 is fixedly connected to the bottom of the sub-button top shell 4. The locking rod 219 is locked inside the connecting block 220. The first spring 210 provides a pushing force to the first pressing button 21. After pressing and releasing the first pressing button 21, the first spring 210 drives the first pressing button 21 to reset. To a certain extent, this prevents the locking rod 28 from being opened due to accidental activation of the first pressing button 21 by external factors, which would affect the locking between the buckles. A slide rail is provided on the sub-button bottom shell 1 at the relative position of the second pressing button 213. The second pressing button 213 slides... Connected inside the slide rail, a groove restricts the sliding of the second pressing button 213, preventing it from tilting or detaching from the bottom shell 1, which would affect the subsequent engagement of the locking rod 219 and the connecting block 220. The second slider 216 has a groove at a position relative to the first linkage rod 215, with the first linkage rod 215 slidably connected inside the groove. The groove restricts the sliding of the first linkage rod 215, preventing it from detaching from the second slider 216 and affecting its subsequent movement. The connecting block 220 has a slot at a position relative to the locking rod 219, with the locking rod 219 engaging inside the slot. This engagement between the locking rod 219 and the connecting block 220 is more convenient and faster than the traditional bolt-fixed buckle housing method, improving overall maintenance efficiency.
[0024] During operation, pressing the first pressing button 21 moves the first connecting rod 22, causing the first sliding block 25 to slide outside the first guide rod 24. This causes the locking rod 28 to slide inward, inserting it into the female buckle body 5. Releasing the first pressing button 21 then provides a pushing force to the first sliding block 25 via the second spring 212, pushing the locking rod 28 and the first sliding block 25 outward. The first spring 210 provides a pushing force to the first pressing button 21, pushing it back to its original position. This engages the locking rod 28 with the female buckle body 5, thus connecting the female and male buckles. If the locking rod 28 is damaged, loosening the fastening bolt 27 releases the restriction on the first insertion rod 26, allowing the locking rod 28 to be removed and replaced. After replacement, the first insertion rod 26 is aligned with the locking mechanism of the first connecting rod 22. After the slot is inserted, align the threaded hole of the first insertion rod 26 with the threaded hole of the first connecting rod 22, and then thread the fastening bolt 27 into it to complete the replacement of the locking rod 28. When the sub-buckle top shell 4 needs to be disassembled, press the second pressing button 213 to move the second connecting rod 214. When the second connecting rod 214 moves, it drives the second slider 216 to slide through the first linkage rod 215. When the second slider 216 slides, it drives the locking rod 219 to slide inward, releasing the locking of the connecting block 220. After removing the connecting block 220, inspect and maintain the components inside the sub-buckle. After inserting the connecting block 220 into the sub-buckle bottom shell 1, the third spring 218 provides a pushing force to the second slider 216, pushing the second slider 216 to slide back to its original position, driving the locking rod 219 to lock with the connecting block 220 to complete the fixing of the sub-buckle top shell 4.
[0025] Through the above steps, compared with the traditional method of deforming the clamping rod 28 by squeezing, the movement of the clamping rod 28 is driven by the sliding of the first sliding block 25, which avoids the clamping rod 28 from bending under force. This solves the problem that the method of disassembling and snapping by relying on the deformation of the sub-clamp itself will gradually lead to a decrease in the strength of the sub-clamp itself during long-term use, eventually leading to an unstable snapping or even the breakage of the sub-clamp.
