Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more specifically, it relates to a quick-release fastener. Background Art

[0002] In the existing technology, as a commonly used connecting device, the design and function of fasteners directly affect the installation efficiency and use safety of products. However, most of the current fasteners on the market have many limitations and cannot meet the diverse needs of modern production and construction. These problems not only reduce work efficiency but may also affect product quality and operation safety.

[0003] First of all, the installation operation of traditional fasteners is usually cumbersome and complex. This design is unable to cope when faced with scenarios that require quick fixing. Specifically, it is manifested as follows: the operation steps are numerous, often requiring multiple steps to complete the installation, increasing the time cost; it is highly dependent on tools, usually requiring special tools for installation, increasing the complexity of the operation; the efficiency is low. In the case of batch installation or emergency fixing, the cumbersome installation process seriously affects work efficiency. These problems result in the inability to achieve rapid assembly of fasteners, thus unable to meet the need for quick fixing of products, which has an adverse impact on production efficiency and cost control.

[0004] Secondly, some manufacturers have realized this problem and started to introduce some mechanisms in the fastener design to achieve quick fixing of products. This is undoubtedly a progress, but new problems have emerged. These designs often only consider the convenience of installation while ignoring the importance of the disassembly process. The specific problems include: difficult disassembly. Although quick fixing is achieved, when disassembly is required, cumbersome operations still need to be carried out with the help of tools; tool dependence, many designs require special tools to complete disassembly, increasing the complexity of on-site operations; difficult maintenance, the complex quick-fixing mechanism increases the maintenance difficulty and may lead to a shortened service life of the equipment; operation risk, the cumbersome disassembly process increases the risk of operation errors and may affect work safety. The existence of these problems severely restricts the practicality of such fasteners and makes them unable to play their due role in scenarios that require frequent disassembly and assembly.

[0005] Finally, some manufacturers have tried to achieve both quick fixation and quick removal by designing simplified structures. However, these designs often focus too much on convenience and neglect the crucial factor of structural stability, which is manifested as follows: insufficient strength, in order to achieve quick connection and disconnection, simplified locking mechanisms are often used, resulting in a reduction in the overall structural strength; risk of accidental unlocking, simple locking devices are prone to accidental loosening or detachment due to vibration or external forces, seriously threatening the use safety; decreased accuracy, unstable structures may cause slight changes in the fixed position during use, affecting product performance; high maintenance costs, unstable structures may require more frequent inspections and maintenance, increasing the usage cost. The existence of these problems severely restricts the practicality and reliability of such quick-release fasteners. They not only affect work efficiency and product quality but also may pose safety hazards. Summary of the Utility Model

The mating groove 9 is opened on the outer side of the mating sleeve 8, and the mating groove 9 is designed as a spiral structure. The mating block 10 is slidably arranged in the mating groove 9. The mating block 10 is fixedly connected to the inner side of the mating plate 11. The mating plate 11 is fixedly connected to one side of the control sleeve 7. The limiting groove 12 is opened on the side wall of the control sleeve 7. A locking mechanism is provided on the outer side of the fastening sleeve 2.

[0032] Both sides of the fastening rod 1 and the fastening sleeve 2 are fixedly connected with fixing plates 13.

[0033] A push spring 14 is movably arranged in the fastening sleeve 2, and the other end of the push spring 14 is connected with a push plate 15.

[0034] A rotating shaft 16 is arranged in the movable groove 4, and the movable plate 3 and the fastening plate 6 are rotatably arranged in the movable groove 4 through the rotating shaft 16.

[0035] In this embodiment, when the device needs to be disassembled, first rotate the locking sleeve 17 so that the locking sleeve 17 moves spirally along the thread provided on the outer side of the fastening sleeve 2. Then, the outer side of the locking rod 18 will lose the limit of the inner side of the locking sleeve 17. Then, rotate the control sleeve 7, and the control sleeve 7 will drive the locking rod 18 to move. Then, the side wall of the locking groove 19 will squeeze the end of the locking rod 18. Due to the rounded corner structure design at the edge of the locking groove 19 and the end of the locking rod 18, one end of the locking rod 18 will slide out of the locking groove 19. Then, the other end of the locking rod 18 will drive the return spring 20 to stretch. At the same time, the control sleeve 7 will drive the mating plate 11 connected to one side to rotate. Then, the mating plate 11 will drive the mating block 10 provided on the inner side to rotate. Due to the spiral structure design of the mating groove 9 and the adaptability of the mating block 10, the mating block 10 slides in the mating groove 9. Since the movable plate 3 and the limiting groove 12 cooperate to limit the mating sleeve 8, the mating sleeve 8 will slide along the side wall of the locking sleeve 17. Then, the mating sleeve 8 will drive the limiting groove 12 to move. Then, one side of the inner wall of the limiting groove 12 will squeeze one side of the movable plate 3, causing the movable plate 3 to drive the fastening plate 6 to rotate along the rotating shaft 16 in the movable groove 4. Then, the fastening plate 6 will gradually screw out of the fastening groove 5 and gradually screw into the movable groove 4. When the mating sleeve 8 stops moving, the fastening plate 6 completely enters the movable groove 4. At this time, the fastening groove 5 loses the limit and engagement of the fastening plate 6. Then, the push spring 14 provided on the inner side of the fastening sleeve 2 will reset. Then, the push spring 14 will push the push plate 15 to move, causing the push plate 15 to push the fastening rod 1 to move, so as to promote the separation of the fastening rod 1 and the fastening sleeve 2. Then, pull the fastening sleeve 2 and the fastening rod 1 to both sides respectively, and the rapid disassembly of the fastening sleeve 2 and the fastening rod 1 can be realized. At the same time, the return spring 20 will drive the locking rod 18 to reset.

[0036] Please refer to Figures 1-5 , as an implementation manner of the locking mechanism: The locking mechanism includes a locking sleeve 17, a locking rod 18 and a locking groove 19.

[0037] A return spring 20 is connected to the outer side of the control sleeve 7, and the other end of the locking rod 18 is connected to the outer wall of the control sleeve 7 through the return spring 20.

[0038] The edges of the locking groove 19 and the ends of the locking rod 18 are both designed with rounded corners.

[0039] Anti-slip strips 21 are connected to the outer sides of the control sleeve 7 and the locking sleeve 17.

[0040] More specifically, when it is necessary to use this device to fix a product, first pass the fastening rod 1 through one side of the product, and then sleeved the fastening sleeve 2 onto the outer side of the fastening rod 1 from the other side of the product. Due to the chamfer structure design at one end of the fastening rod 1, one end of the fastening rod 1 will then push the locking rod 18 to move, causing the locking rod 18 to drive the return spring 20 to stretch again. Then one end of the fastening rod 1 will abut against the push plate 15, and then the fastening rod 1 will push the push plate 15 to compress the push spring 14. When the push spring 14 is compressed to the limit, rotate the control sleeve 7 in the reverse direction. Then the control sleeve 7 will drive the mating plate 11 connected to one side to rotate. Then, through the cooperation of the mating block 10 and the mating groove 9, the mating sleeve 8 will be driven to slide and reset. Then the mating sleeve 8 will drive the limiting groove 12 to reset. Then the other side of the inner wall of the limiting groove 12 will squeeze the other side of the movable plate 3, causing the movable plate 3 to drive the fastening plate 6 to rotate and reset along the rotating shaft 16. Then the fastening plate 6 will gradually rotate from the movable groove 4 into the fastening groove 5. Then the fastening plate 6 will form a clamping relationship with the fastening groove 5 again, so that the fastening rod 1 is clamped into the fastening sleeve 2. At this time, the return spring 20 will drive the locking rod 18 to reset, causing the locking rod 18 to be clamped into the original locking groove 19. Then rotate the locking sleeve 17 in the reverse direction. Then the locking sleeve 17 will reset along the thread line provided on the outer side of the fastening sleeve 2. Then the inner wall of the locking sleeve 17 will limit the outer end of the locking rod 18 again to prevent the locking rod 18 from moving. Then the locking rod 18 will cooperate with the locking groove 19 to limit the control sleeve 7 to prevent accidental unlocking, enhancing the structural stability.

[0041] In summary, when the overall device is in use or operation: when the device needs to be disassembled, first rotate the locking sleeve 17 so that the locking sleeve 17 moves spirally along the thread line provided on the outer side of the fastening sleeve 2. Then, the outer side of the locking rod 18 will lose the limit of the inner side of the locking sleeve 17. Then, rotate the control sleeve 7, and the control sleeve 7 will drive the locking rod 18 to move. Then, the side wall of the locking groove 19 will squeeze the end of the locking rod 18. Due to the rounded corner structure design at the edge of the locking groove 19 and the end of the locking rod 18, one end of the locking rod 18 will slide out of the locking groove 19. Then, the other end of the locking rod 18 will drive the return spring 20 to stretch. At the same time, the control sleeve 7 will drive the mating plate 11 connected on one side to rotate. Then, the mating plate 11 will drive the mating block 10 provided on the inner side to rotate. Due to the spiral structure design of the mating groove 9 and the adaptability of the mating block 10, the mating block 10 slides in the mating groove 9. Since the movable plate 3 and the limiting groove 12 cooperate to limit the mating sleeve 8, the mating sleeve 8 will slide along the side wall of the locking sleeve 17. Then, the mating sleeve 8 will drive the limiting groove 12 to move. Then, one side of the inner wall of the limiting groove 12 will squeeze one side of the movable plate 3, causing the movable plate 3 to drive the fastening plate 6 to rotate along the rotating shaft 16 in the movable groove 4. Then, the fastening plate 6 will gradually screw out of the fastening groove 5 and gradually screw into the movable groove 4. When the mating sleeve 8 stops moving, the fastening plate 6 completely enters the movable groove 4. At this time, the fastening groove 5 loses the limit and engagement of the fastening plate 6. Then, the push spring 14 provided on the inner side of the fastening sleeve 2 will reset. Then, the push spring 14 will push the push plate 15 to move, causing the push plate 15 to push the fastening rod 1 to move, thereby promoting the separation of the fastening rod 1 and the fastening sleeve 2. Then, pull the fastening sleeve 2 and the fastening rod 1 to both sides respectively, and the quick disassembly of the fastening sleeve 2 and the fastening rod 1 can be achieved. At the same time, the return spring 20 will drive the locking rod 18 to reset.

[0042] When the device is needed to fix a product, first pass the fastening rod 1 through one side of the product, and then sleeved the fastening sleeve 2 from the other side of the product onto the outside of the fastening rod 1. Due to the chamfer structure design at one end of the fastening rod 1, one end of the fastening rod 1 will push the locking rod 18 to move, so that the locking rod 18 drives the return spring 20 to stretch again. Then one end of the fastening rod 1 will abut against the push plate 15, and then the fastening rod 1 will push the push plate 15 to compress the push spring 14. When the push spring 14 is compressed to the limit, rotate the control sleeve 7 in the reverse direction. Then the control sleeve 7 will drive the mating plate 11 connected to one side to rotate. Then, through the cooperation of the mating block 10 and the mating groove 9, the mating sleeve 8 is driven to slide and reset. Then the mating sleeve 8 will drive the limiting groove 12 to reset. Then the other side of the inner wall of the limiting groove 12 will squeeze the other side of the movable plate 3, so that the movable plate 3 drives the fastening plate 6 to rotate and reset along the rotating shaft 16. Then the fastening plate 6 will gradually turn from the movable groove 4 into the fastening groove 5. Then the fastening plate 6 will form a clamping relationship with the fastening groove 5 again, so that the fastening rod 1 is clamped into the fastening sleeve 2. At this time, the return spring 20 will drive the locking rod 18 to reset, so that the locking rod 18 is clamped into the original locking groove 19. Then rotate the locking sleeve 17 in the reverse direction. Then the locking sleeve 17 will reset along the thread line provided on the outside of the fastening sleeve 2. Then the inner wall of the locking sleeve 17 will limit the outer end of the locking rod 18 again to prevent the locking rod 18 from moving. Then the locking rod 18 will cooperate with the locking groove 19 to limit the control sleeve 7 to prevent accidental unlocking, enhancing the stability of the structure.
