Description

Technical Field

[0001] This utility model relates to the field of quick-release structure technology, and in particular to a spring-loaded snap-lock quick-locking and disassembly structure. Background Technology

[0002] Quick-release mechanisms are mechanical connection devices that enable rapid disassembly or assembly of components. Due to their ease of operation and high efficiency, they are widely used in industrial equipment, furniture, medical devices, and other fields. In the industrial equipment sector, common quick-release mechanisms mainly include hydraulic / pneumatic quick-release mechanisms and spring-loaded snap-on quick-release mechanisms.

[0003] Spring-loaded quick-release structures typically employ a built-in spring ball or elastic latch design. By inserting the spring into the corresponding groove, the deformation of the elastic element achieves instantaneous engagement, thus realizing automatic locking. However, existing spring-loaded quick-release structures still have the following technical drawbacks: 1. High assembly precision requirements and low operational efficiency. During assembly, the parts to be connected must be precisely aligned with the groove to allow the spring ball or elastic latch to smoothly engage and lock. Since the alignment process relies on manual adjustment, the operation is cumbersome and time-consuming, affecting assembly efficiency. 2. Prone to jamming during disassembly, resulting in insufficient reliability. During disassembly, the spring ball or elastic latch may jam due to frictional resistance, material fatigue, or structural deformation, preventing it from smoothly exiting the groove. This not only reduces operational convenience but may also affect the reusability of the structure. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems of the prior art and provide a spring-loaded snap-lock quick-locking and disassembly structure, which has the advantages of high snap-locking and disassembly efficiency, convenient operation and stable operation.

The lifting spring acts on the sliding push block, so that: the top of the sliding push block abuts against the bottom of the positioning frame, the sliding push block is directly facing the area where the unlocking protrusion is located, and the push block linkage section extends out of the pressing port.

[0013] When the sliding push block is pressed down, so that the bottom end of the sliding push block abuts against the top end of the spring base, the sliding push block is directly opposite the area where the locking groove is located.

[0014] Furthermore, a rotating synchronizing disk is also provided inside the housing, located below the two clamps and rotatable relative to the housing;

[0015] The bottom end of the unlocking rod segment is provided with an unlocking limit protrusion;

[0016] The rotating synchronous disk has two unlocking limit strip openings that slide in conjunction with two unlocking limit protrusions.

[0017] Furthermore, the bottom end of the rotating synchronous disk is provided with an annular disk limiting protrusion;

[0021] Furthermore, a lifting limiting groove is provided at the bottom end of the push block limiting section;

[0022] The spring base is provided with a lifting limit post in the base receiving groove;

[0023] The upper and lower ends of the lifting spring are located in the lifting limiting groove and the receiving groove, respectively, and the lower end of the lifting spring is sleeved on the lifting limiting post.

[0024] Furthermore, the other end of the unlocking rod segment has an unlocking head located outside the housing and with a width greater than the width of the unlocking port.

[0025] Furthermore, the housing includes an upper housing and a lower housing detachably connected to the bottom end of the upper housing;

[0026] The lower housing has a lower receiving groove for accommodating the spring base and the lower ends of the two clamps;

[0027] The upper housing has an upper receiving groove for accommodating the positioning frame and the upper ends of the two clamps.

[0028] Furthermore, the inner wall of the lower housing is provided with a clamping and limiting groove A;

[0029] The outer surface of the chuck is provided with a clamping limiting groove B corresponding to the clamping limiting groove A;

[0030] The two ends of the clamping spring are located in clamping limiting groove A and clamping limiting groove B, respectively.

[0031] Furthermore, a positioning and fixing section that is misaligned with the clamp section is connected to the side wall of the positioning frame. The positioning and fixing section is detachably connected to the lower housing and a positioning through hole is also provided on the positioning and fixing section.

[0032] The top of the lower housing is also provided with a positioning post that engages with the positioning through hole;

[0035] This utility model has the following beneficial effects: Through innovative mechanical linkage structure and optimized spatial layout design, this utility model achieves significant performance improvement, specifically manifested in the following technical advantages:

[0036] 1. Locking Operation: A single downward press of the push block linkage section synchronously drives the two clamping sections to move in opposite directions, ensuring stable three-point contact between the clamping groove and the component to be fixed, thus achieving rapid locking. This design simplifies the traditional multi-step locking process into a single action, effectively improving operational efficiency.

[0037] 2. Unlocking operation: The symmetrically arranged unlocking lever segments only require radial pressure to synchronously drive the two clamp segments to separate, thereby achieving a fast unlocking operation. In particular, the design of rotating the synchronous disk can effectively improve the synchronicity of the radial movement of the two clamps, thereby improving the reliability of unlocking.

[0038] 3. Reset and holding function: The lifting spring adopts a pre-compression design (it is in a compressed state when locked) and can maintain a stable elastic restoring force when unlocked, ensuring that the sliding push block is accurately reset to the initial position, providing a reliable standby state for the next assembly;

[0039] 4. Low-friction motion system: The spring structures inside the housing adopt a large-space layout design, which effectively reduces the frictional resistance during the deformation process of the elastic elements and ensures the smooth movement of each component.

[0040] It is evident that this utility model has made significant progress in terms of locking and unlocking efficiency, ease of operation, and operational stability, and is particularly suitable for the high-end equipment manufacturing field that requires frequent disassembly and assembly.

[0056] To enable those skilled in the art to better understand this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0057] Example 1

[0058] like Figures 1 to 16As shown, the spring-loaded snap-lock quick-locking and disassembly structure includes a housing 1, with a locking port 36 at the top and unlocking ports 16 on both sides of the housing 1.

[0059] Two symmetrically arranged clamps 8 are installed inside the housing 1. Each clamp 8 has an unlocking rod section 10 that can slide radially relative to the housing 1 and a clamping section 11 connected to one end of the unlocking rod section 10. The inner end of the clamping section 11 is provided with a clamping groove 13, an unlocking protrusion 14 and a locking groove 15 connected sequentially from top to bottom.

[0060] The inner wall of the housing 1 is provided with clamping springs 12 that act on the chucks 8. The two clamping springs 12 act on the two chucks 8 respectively, so that the two chuck sections 11 always tend to move closer to each other, and the other ends of the two unlocking rod sections 10 can extend out of the two unlocking ports 16 respectively.

[0061] Inside the housing 1, in the area between the two clamping sections 11, a positioning frame 2, a sliding push block 3, and a spring base 4 are arranged sequentially from top to bottom;

[0062] The positioning frame 2 is fixed on the housing 1 and located in the area directly opposite the clamping groove 13. The positioning frame 2 has a pressing port 5.

[0063] The top of the sliding pusher 3 has a pusher linkage section 6, and the sliding pusher 3 can move axially relative to the housing 1;

[0064] A lifting spring 7 is provided on the spring base 4. The lifting spring 7 acts on the sliding push block 3, so that: the top of the sliding push block 3 abuts against the bottom of the positioning frame 2, the sliding push block 3 is directly facing the area where the unlocking protrusion 14 is located, and the push block linkage section 6 extends out of the pressing port 5.

[0065] When the sliding push block linkage section 6 is pressed down, so that the bottom end of the sliding push block 3 abuts against the top end of the spring base 4, the sliding push block 3 is directly facing the area where the locking groove 15 is located.

[0066] In this embodiment, the shell 1 can be a cylindrical shape with a closed bottom, so as to... Figure 3 For example, the radial sliding of the unlocking rod segment 10 allows it to move left and right relative to the housing 1; the axial movement of the sliding push block 3 allows it to move up and down relative to the housing 1.

[0067] In this embodiment, when in the zero position, the sliding push block 3 moves upward under the action of the lifting spring 7 to abut against the positioning frame 2. At this time, the sliding push block 3 is directly opposite the unlocking protrusion 14, and the two clamping sections are in an expanded (unlocked) state due to the abutment relationship between the unlocking protrusion 14 and the sliding push block 3. Then, the component to be connected is inserted into the housing 1 through the locking port 36 and the push block linkage section 6 is pressed down until the bottom end of the sliding push block 3 abuts against the top end of the spring base 4. At this time, the sliding push block 3 is directly opposite the area where the locking groove 15 is located, and the two clamping sections 11 will move rapidly towards each other under the action of the two clamping springs 12, thereby driving the clamping groove 13 to quickly clamp the component to be connected.

[0068] When unlocking is required, the other ends of the two unlocking rod segments 10 are pressed radially inward at the same time, and the two clamp segments 11 will be in the expanded (unlocked) state again. At this time, the sliding push block 3 will move up quickly under the support of the lifting spring 7 and abut against the positioning frame 2 again. The sliding push block 3 will also be in the position facing the unlocking protrusion 14 again. In this way, the unlocked state of this embodiment can be maintained for the next assembly work.

[0069] In this embodiment, simply pressing down on the push block linkage section 6 synchronously drives the two clamp sections 11 to move towards each other, thereby achieving a rapid locking operation; simply pressing the two unlocking rod sections 10 radially inward synchronously drives the two clamp sections 11 to separate, thereby achieving a rapid unlocking operation. Furthermore, the lifting spring's reset action on the sliding push block 3 maintains this unlocked state for future assembly work. Therefore, this embodiment offers advantages of convenient operation and stable performance in both locking and unlocking operations.

[0070] In addition, such as Figure 10 As shown, in the chuck 8, the two chuck segments 11 should be symmetrically arranged on both sides of the positioning frame 2, so that the parts to be connected can be clamped more stably; the two unlocking rod segments 10 should be staggered so that they do not interfere with each other and move towards or away from each other.

[0071] Preferably, the housing 1 is further provided with a rotating synchronizing disk 9 located below the two clamps 8 and rotatable relative to the housing 1;

[0072] The bottom end of the unlocking rod segment 10 is provided with an unlocking limit protrusion 17;

[0073] The rotating synchronous disk 9 has two unlocking limit strip openings 18 that slide in conjunction with two unlocking limit protrusions 17.

[0074] In this embodiment, the rotating synchronization disk 9 ensures the synchronicity of the two unlocking rod segments 1 moving towards or away from each other, and also helps to improve the stability of the two unlocking rod segments 10 during radial movement. Specifically, when the unlocking rod segment 10 moves radially outward under the support of the clamping spring 12, or radially inward under the action of external force, even if the two unlocking rod segments 10 are out of sync under the aforementioned pressures, as long as any one of the unlocking limiting strip openings 18 in the rotating synchronization disk 9 engages with the corresponding unlocking limiting protrusion 17, that is, the unlocking limiting protrusion 17 will slide within the unlocking limiting strip opening 18, causing the rotating synchronization disk 9 to rotate appropriately to accommodate the aforementioned radial inward and outward movement position requirements. In this way, it will inevitably cause the other unlocking limiting strip opening 18 to engage with the other corresponding unlocking limiting protrusion 17 to achieve a synchronization effect.

[0075] Preferably, the bottom end of the rotating synchronous disk 9 is provided with an annular disk limiting protrusion 29;

[0076] The inner wall of the housing 1 is provided with a turntable limiting groove 30 that rotates in conjunction with the turntable limiting protrusion 29.

[0077] In this embodiment, the stability of the rotation of the synchronous disk 9 can be improved by the cooperation of the turntable limiting protrusion 29 and the turntable limiting protrusion 29, so as to better limit the radial movement of the two unlocking rod segments 10.

[0078] Preferably, the bottom end of the sliding push block 3 is provided with a push block limiting section 31, and the side wall of the push block limiting section 31 is provided with a push block limiting protrusion 32.

[0079] The spring base 4 has a base receiving groove 33 that can accommodate the push block limiting section 31, and the groove wall of the base receiving groove 33 has a push block limiting groove 34 that cooperates with the push block limiting protrusion 32.

[0080] In this embodiment, the stability of the axial movement of the sliding push block 3 can be improved by the cooperation between the push block limiting section 31 and the base receiving groove 33; the stability of the axial movement of the sliding push block 3 can be further improved by the cooperation between the push block limiting groove 34 and the push block limiting protrusion 32.

[0081] Preferably, the bottom end of the push block limiting section 31 is provided with a lifting limiting groove 35;

[0082] The spring base 4 is provided with a lifting limit post 38 in the base receiving groove 33;

[0083] The upper and lower ends of the lifting spring 7 are located in the lifting limiting groove 35 and the receiving groove 33 respectively, and the lower end of the lifting spring 7 is sleeved on the lifting limiting post 38.

[0084] In this embodiment, the lifting limiting groove 35, the lifting limiting post 38, and the receiving groove 33 can improve the stability of the lifting spring 7 during the elastic deformation process and prevent it from shifting its position.

[0085] Preferably, the other end of the unlocking rod segment 10 has an unlocking head 19 located outside the housing 1 and with a width greater than the width of the unlocking port 16.

[0086] In this embodiment, the setting of the unlocking head 19 makes it easier for the operator to move the unlocking rod segment 10 radially inward to unlock the two clamp segments 11, thereby improving the reliability of operation.

[0087] Preferably, the housing 1 includes an upper housing 23 and a lower housing 24 detachably connected to the bottom end of the upper housing 23;

[0088] The lower housing 24 is provided with a lower receiving groove 25 for accommodating the lower ends of the spring base 4 and the two clamps 8;

[0089] The upper housing 23 has an upper receiving groove 26 for accommodating the positioning frame 2 and the upper ends of the two clamps 8.

[0090] To facilitate the assembly of structures such as the two clamps 8, the positioning frame 2, the sliding push block 3, and the spring base 4, the housing 1 can be composed of two parts: the upper housing 23 and the lower housing 24.

[0091] Preferably, the inner wall of the lower housing 24 is provided with a clamping and limiting groove A20;

[0092] The outer surface of the chuck 8 is provided with a clamping and limiting groove B21 corresponding to the clamping and limiting groove A20;

[0093] The two ends of the clamping spring 12 are located in the clamping limiting groove A20 and the clamping limiting groove B21, respectively.

[0094] In this embodiment, by setting the clamping limiting groove A20 and the clamping limiting groove B21, the stability of the clamping spring 12 during the elastic deformation process can be improved, and its position displacement can be avoided.

[0095] Preferably, the side wall of the positioning frame 2 is connected to a positioning and fixing section 22 that is misaligned with the clamping section 11. The positioning and fixing section 22 is detachably connected to the lower housing 24. The positioning and fixing section 22 is also provided with a positioning through hole 27.

[0096] The top of the lower housing 24 is also provided with a positioning post 28 that engages with the positioning through hole 27;

[0097] The bottom end of the upper housing 23 is provided with a clearance blind hole 39 that cooperates with the positioning post 28.

[0098] In this embodiment, to achieve a suspended fixed connection of the positioning frame 2 within the housing 1, a positioning and fixing section 22 connected to the lower housing 24 is designed. The cooperation between the positioning post 28 and the positioning through hole 27 enables rapid positioning of the positioning frame 2 on the lower housing 24, improving assembly efficiency.

[0099] Preferably, it also includes a snap-fit ​​adapter 37, which can be inserted into the locking port 36 and press down the push block linkage section 6.

[0100] In this embodiment, the snap-fit ​​adapter 37 has an adapter clamping section 40 that can be adapted to the clamping groove 13. In application, the snap-fit ​​adapter 37 is connected to the component to be connected, and then quickly assembled in this embodiment. It is evident that the snap-fit ​​adapter 37 enhances the versatility of this embodiment, enabling the quick assembly and disassembly of various components of different specifications and shapes.

It should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, other embodiments derived without departing from the technical solution of the present invention should be included within the protection scope of the present invention.
