Description

Technical Field

[0001] This utility model relates to the field of fastening structure technology, specifically a quick-assembly and disassembly fastening structure. Background Technology

[0002] Fasteners are indispensable basic components in mechanical equipment, and their performance directly affects the safety and maintenance efficiency of the equipment. However, traditional fasteners (such as bolts, nuts, and snap-fit ​​connectors) have significant limitations in practical applications:

[0003] Low operational efficiency: Reliance on specialized tools such as wrenches and screwdrivers for assembly and disassembly severely restricts work efficiency in high-frequency maintenance scenarios;

[0004] Rapid reliability degradation: Repeated disassembly and assembly can easily lead to failure modes such as thread stripping and snap-fit ​​stress fracture, resulting in a significant decrease in connection reliability over the service life;

[0005] High maintenance costs: The entire connector needs to be replaced after the threads wear out, and broken clips may cause secondary losses such as equipment downtime.

[0006] While existing quick-connect technologies (such as magnetic and elastic snap-fit) have improved the ease of assembly and disassembly through structural innovation, they generally have shortcomings in mechanical performance: magnetic connections are prone to loosening under vibration conditions, and elastic snap-fits have limited fixing strength.

[0007] Therefore, an improved quick-assembly and fastening structure is needed to address the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a quick-release fastening structure to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a quick-release fastening structure, comprising a first mounting block, a second mounting block disposed on one side of the first mounting block, and a fixing mechanism disposed between the first mounting block and the second mounting block. The fixing mechanism includes a rotating component, a connecting rod, a buckle, a slider, and a limiting block. The first mounting block is provided with a rotating component, which is movably connected to the first mounting block so that the rotating component can rotate around the first mounting block. A connecting rod is fixedly disposed at one end of the rotating component. A buckle is fixedly disposed on the outer surface of the second mounting block. A slider is movably sleeved on the outer surface of the connecting rod. A limiting block is fixedly disposed on the surface of the slider, and the limiting block is movably engaged inside the buckle.

[0010] Preferably, a handle is fixedly provided at the end of the connecting rod away from the rotating part, so that the rotating part can be easily rotated by the handle.

[0011] Preferably, a spring is fitted on the outer surface of the connecting rod between the handle and the buckle, so that the spring can automatically spring up to push the limiting block into the buckle.

[0012] Preferably, extension rods are fixedly provided on both sides of the slider surface. When the user grips the handle, they can extend their fingers to hook the extension rods, thereby driving the extension rods, slider, and limiting block to move towards the handle, forming... Figure 2 As shown in the diagram, the connecting rod and rotating parts are then rotated to tighten or loosen the fastener.

[0013] Preferably, both the first mounting block and the second mounting block are fixedly provided with fixing screws at their lower ends. The fixing screws can be used to easily fix the device in the position that needs to be tightened, and one side can be installed and used multiple times. The fixing screws are only one way to install the device. If necessary, welding can be used to fix the first mounting block and the second mounting block to the target position.

[0014] Preferably, the outer surface of the limiting block is chamfered, which facilitates the limiting block to be inserted into the buckle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model's quick-release fastening structure, through the synergistic action of the fixing mechanism, enables tool-free quick assembly and disassembly, effectively solving the problems of traditional fasteners' reliance on tools and low efficiency. The handle provides a convenient point of force for rotating the component, and the spring pushes the limit block to automatically engage with the buckle, greatly simplifying the fastening operation. Furthermore, hooking the extension rod with a finger disengages the limit block from the buckle, allowing for disassembly in conjunction with rotating the handle; the entire process is fast and efficient.

[0017] 2. In terms of connection stability, the precise engagement of the limiting block and the buckle, combined with the elastic support of the spring, can form a stable fastening effect, which is stronger than that of magnetic fasteners. At the same time, the rigid connection of each component of the device is combined with the elastic auxiliary design, which avoids the problem of easy failure of the elastic buckle after long-term use and improves the overall durability.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a quick-release fastening structure, including a first mounting block 1, a second mounting block 2 disposed on one side of the first mounting block 1, and a fixing mechanism disposed between the first mounting block 1 and the second mounting block 2. The fixing mechanism includes a rotating component 3, a connecting rod 4, a buckle 5, a slider 6, and a limiting block 7. The first mounting block 1 is provided with a rotating component 3, which is movably connected to the first mounting block 1. A connecting rod 4 is fixedly disposed at one end of the rotating component 3. A buckle 5 is fixedly disposed on the outer surface of the second mounting block 2. A slider 6 is movably sleeved on the outer surface of the connecting rod 4. A limiting block 7 is fixedly disposed on the surface of the slider 6, and the limiting block 7 is movably engaged inside the buckle 5.

[0025] A handle 8 is fixedly installed at the end of the connecting rod 4 away from the rotating part 3. The user can easily rotate the rotating part 3 by holding the handle 8 without additional tools. A spring 9 is sleeved on the outer surface of the connecting rod 4 between the handle 8 and the buckle 5. When no external force is applied, the elastic thrust of the spring 9 can push the slider 6 towards the buckle 5, thereby causing the limiting block 7 to automatically engage inside the buckle 5, completing the automatic fastening. Extension rods 10 are fixedly installed on both sides of the slider 6. When disassembly is required, the user holds the handle 8 and hooks the extension rod 10 with their fingers and pulls it towards the handle 8. The extension rod 10 moves the slider 6 and the limiting block 7, causing the limiting block 7 to disengage from the buckle 5. Then, rotating the handle 8 will rotate the connecting rod 4 and the rotating part 3, thus completing the fastening release.

[0026] Both the first mounting block 1 and the second mounting block 2 are fixedly equipped with fixing screws 11 at their lower ends. The fixing screws 11 can be used to quickly install the device at the target position, which is convenient for multiple disassembly and reuse. If the scenario requires stronger connection stability, the first mounting block 1 and the second mounting block 2 can be fixed to the target position by welding. The chamfered structure on the outer surface of the limiting block 7 can reduce frictional resistance when the limiting block 7 is engaged with the buckle 5, making the engagement process smoother.

[0027] Working Principle: In practical applications, this device can be used on flip-top components. The first mounting block 1 can be installed on the main body of the equipment using fixing screws 11, and the second mounting block 2 can be installed on the flip-top component. When the flip-top is closed, rotating the handle 8 drives the connecting rod 4 and the rotating part 3 to rotate, so that the limiting block 7 aligns with the buckle 5. The spring 9 pushes the slider 6 and the limiting block 7 into the buckle 5, thus securing the flip-top. When it is necessary to open the flip-top, hooking the extension rod 10 causes the limiting block 7 to disengage from the buckle 5, and rotating the handle 8 opens the flip-top. The operation is convenient and efficient. First, the first mounting block 1 is fixed to the main body of the equipment using the fixing screws 11 at the lower end of the first mounting block 1. Then, the second mounting block 2 is fixed to the flip-top component using the fixing screws 11 (or by welding) at the lower end of the second mounting block 2, thus completing the basic installation and positioning of the device.

[0028] When disassembling, apply force to separate the limiting block 7 and the buckle 5: The user maintains the posture of holding the handle 8, and at the same time hooks the extension rods 10 on both sides of the slider 6 with his fingers and pulls the extension rods 10 towards the handle 8; the extension rods 10 drive the slider 6 to move along the connecting rod 4 towards the handle 8. During the movement of the slider 6, the spring 9 is compressed, and at the same time, the limiting block 7 is disengaged from the buckle 5, releasing the locking state of the two.

[0029] Disassembly is completed by rotating: After the limiting block 7 separates from the buckle 5, continue to hold the handle 8 and rotate the connecting rod 4 and the rotating part 3 so that the entire fixing mechanism rotates out of the buckle 5 area of ​​the second mounting block 2. At this time, the flip cover part loses its fixed constraint and can be easily opened to complete the disassembly operation.

[0030] Throughout the entire operation, the elastic force of spring 9 provides automatic driving force for fastening, the cooperation between handle 8 and extension rod 10 provides a convenient force application point for disassembly and assembly, and the chamfered structure of limit block 7 ensures smooth engagement. Ultimately, it achieves the core functions of "tool-free, quick disassembly and assembly, and stable fastening," and is compatible with components that require rotational fastening (such as flip covers), avoiding functional failure in lateral pulling scenarios.

[0031] It should be noted that this device is used to fasten parts that need to be rotated, such as flip-top parts; it is not suitable for parts that need to be fastened when pulled horizontally.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
