Description

Technical Field

[0001] This utility model relates to the field of home furnishing equipment technology, and in particular to a quick-release structure. Background Technology

[0002] Quick-release structures are widely used in furniture, medical and health care equipment, and warehouse racking. Their core function is to enable the rapid assembly and disassembly of functional components while ensuring the reliability of component connections, reducing reliance on special tools and thus improving product installation efficiency and ease of maintenance.

[0003] However, existing quick-release structures have the following problems: To achieve a stable connection between components, most structures use multiple components such as bolts, nuts, and locating pins. Users need to operate multiple fasteners one by one during disassembly and assembly, which is not only cumbersome and time-consuming, but also makes it easy to lose small fasteners. To simplify the structure, some quick-release structures use only a single insertion method for connection, which leads to a lack of effective positioning between components during assembly and is prone to radial misalignment. Therefore, existing quick-release structures cannot achieve synchronous positioning and locking of multiple components, making it difficult to balance ease of disassembly and assembly with connection stability.

[0004] Therefore, there is an urgent need for a quick-release structure that can combine positioning and locking functions and simplify the assembly process, thereby solving the above-mentioned technical problems. Utility Model Content

[0036] Quick-release structures are widely used in furniture, medical and health care equipment, and warehouse racking. Their core function is to enable the rapid assembly and disassembly of functional components while ensuring the reliability of component connections, reducing reliance on special tools and thus improving product installation efficiency and ease of maintenance.

[0037] However, existing quick-release structures have the following problems: To achieve a stable connection between components, most structures use multiple components such as bolts, nuts, and locating pins. Users need to operate multiple fasteners one by one during disassembly and assembly, which is not only cumbersome and time-consuming, but also makes it easy to lose small fasteners. To simplify the structure, some quick-release structures use only a single insertion method for connection, which leads to a lack of effective positioning between components during assembly and is prone to radial misalignment. Therefore, existing quick-release structures cannot achieve synchronous positioning and locking of multiple components, making it difficult to balance ease of disassembly and assembly with connection stability.

[0038] Therefore, there is an urgent need for a quick-release structure that can combine positioning and locking functions and simplify the assembly process, thereby solving the above-mentioned technical problems.

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1-6As shown, this embodiment provides a quick-release structure, which includes a mounting component 1, a connector 2, a connecting sleeve 3, and a mounting tube 4. The mounting component 1 has a first through hole 11, the connector 2 has a first locking part 21, and the connecting sleeve 3 has a second through hole 31. The first locking part 21 is sequentially inserted into the first through hole 11 and the second through hole 31, and the mounting tube 4 is detachably sleeved on the connecting sleeve 3.

[0041] In this embodiment, the mounting component 1 has a first through hole 11, the connector 2 has a first locking part 21, and the connecting sleeve 3 has a second through hole 31. The first locking part 21 is inserted into the first through hole 11 and the second through hole 31 in sequence, thereby achieving synchronous positioning and locking of the mounting component 1, the connector 2, and the connecting sleeve 3 through the first locking part 21. This simplifies the assembly steps and prevents the risk of loss caused by multiple scattered fasteners. Moreover, the above-mentioned arrangement ensures the coaxiality of the connection between the mounting component 1, the connector 2, and the connecting sleeve 3, effectively reducing radial offset. The mounting tube 4 can be detachably sleeved onto the connecting sleeve 3, allowing for a reliable connection between the mounting tube 4 and the mounting component 1 through the connector 2 and the connecting sleeve 3. No special disassembly or assembly tools are required, making the operation more convenient and faster. Through the above-mentioned arrangement, the quick-release structure of this embodiment can combine positioning and locking functions, simplifying the assembly process.

[0042] It should be noted that the connection between the mounting tube 4 and the connecting sleeve 3 can be achieved either by detachably fitting the mounting tube 4 onto the outside of the connecting sleeve 3 or by detachably fitting the connecting sleeve 3 onto the outside of the mounting tube 4. No further limitation is made here. Those skilled in the art can choose according to actual working conditions to adapt different sizes and specifications of the mounting tube 4 and the connecting sleeve 3 to meet the needs of diverse assembly scenarios.

[0043] The following is a detailed explanation of the quick-release mechanism:

[0044] Specifically, such as Figures 1-6 As shown, the connecting sleeve 3 includes a connecting cavity 32, which communicates with the second through hole 31. The first locking part 21 is inserted into the connecting cavity 32 to achieve a stable connection between the connecting piece 2 and the connecting sleeve 3. Then, the mounting tube 4 is inserted into the connecting cavity 32 to achieve synchronous positioning and locking of the mounting piece 1, the connecting piece 2, and the connecting sleeve 3. Moreover, by providing the connecting cavity 32, assembly space is provided for the first locking part 21 and the mounting tube 4, which helps to improve the connection stability and assembly accuracy between the above components.

[0045] More specifically, in this embodiment, the mounting tube 4 passes through the connecting sleeve 3, and the first locking part 21 includes a fastening pin. The fastening pin is inserted into the connecting cavity 32 and the interior of the mounting tube 4 through the second through hole 31, thereby locking the mounting part 1, the connecting part 2 and the connecting sleeve 3, thereby improving the connection firmness.

[0046] More specifically, in this embodiment, the connector 2 includes a mounting plate 22, and a first locking part 21 is disposed on the mounting plate 22, providing a stable mounting base for the first locking part 21. The mounting part 1 is disposed between the mounting plate 22 and the connecting sleeve 3, which can distribute the assembly pressure, improve the fit between the above-mentioned components, and thus improve the structural compactness. By having the first locking part 21 pass through the mounting part 1 and the connecting sleeve 3 in sequence, the mounting part 1, the connector 2, and the connecting sleeve 3 form a stable structure.

[0047] Specifically, such as Figures 4-6 As shown, the mounting plate 22 is provided with a second locking part 221, and the mounting component 1 is provided with a third through hole 12. The second locking part 221 is inserted into the third through hole 12, and the second locking part 221 and the third through hole 12 cooperate with each other to further improve the connection stability between the mounting plate 22 and the mounting component 1.

[0048] More specifically, such as Figures 1-4 As shown, in this embodiment, the mounting member 1 has a flat plate structure, and the second locking part 221 includes a locking plate. The locking plate is disposed at one end of the mounting plate 22 and extends outward in a direction perpendicular to the mounting plate 22, which facilitates precise insertion into the third through hole 12. Moreover, the end of the locking plate that passes through the third through hole 12 can be bent, thereby forming a mechanical anti-disengagement limit, improving the connection reliability between the mounting plate 22 and the mounting member 1, and preventing the locking plate from being dislodged from the third through hole 12 by vibration or external force.

[0049] In other embodiments, such as Figure 7 As shown, the second locking part 221 includes fastening pins, which allows for quicker and easier assembly and disassembly compared to a locking plate. The first locking part 21 and the second locking part 221 are spaced apart and positioned on the same side of the mounting plate 22, which ensures that the mounting plate 22 is subjected to balanced forces and improves connection stability.

[0050] It should be noted that the first locking part 21 and / or the second locking part 221 include, but are not limited to, structures such as locking pins, locking plates and locking bolts, so as to adapt to different assembly strength requirements and processing technology and improve structural adaptability.

[0051] Specifically, such as Figures 1-6 As shown, a connecting tube 33 is provided inside the connecting cavity 32. The connecting tube 33 communicates with the second through hole 31. The first locking part 21 is inserted into the connecting tube 33, thereby providing precise guidance for the first locking part 21 and ensuring the accuracy of its insertion position. Moreover, by providing the connecting tube 33 to insert the first locking part 21, the service life of the connecting sleeve 3 can be extended, and stress concentration between the first locking part 21 and the hole wall of the second through hole 31 can be avoided, thus preventing damage to the connecting sleeve 3.

[0052] Specifically, such as Figure 5As shown, the surface of the connecting cavity 32 is connected to the connecting tube 33 by a reinforcing rib 34, which can enhance the structural strength between the surface of the connecting cavity 32 and the connecting tube 33, thereby improving the bending resistance of the connecting tube 33 and preventing the connecting tube 33 from deforming or breaking due to excessive force when the first locking part 21 is inserted.

[0053] More specifically, multiple reinforcing ribs 34 are provided, and the multiple reinforcing ribs 34 are arranged at intervals along the circumference of the connecting pipe 33, so that the connecting pipe 33 is subjected to uniform force in all directions, thereby improving the overall structural stability. The number of reinforcing ribs 34 includes, but is not limited to, four, six, or eight, etc., and is not further limited here.

[0054] Specifically, such as Figures 4-6 As shown, in this embodiment, the mounting tube 4 is provided with a snap-fit ​​hole 41, and the surface of the connecting cavity 32 is provided with an elastic snap-fit ​​member 35. When the mounting tube 4 is inserted into the connecting cavity 32, the elastic snap-fit ​​member 35 is fastened to the snap-fit ​​hole 41. It can be understood that the detachable connection between the mounting tube 4 and the connecting sleeve 3 can be achieved through the elasticity of the elastic snap-fit ​​member 35 itself. This not only eliminates the need for additional tools and improves the efficiency of assembly and disassembly, but also uses the elasticity of the elastic snap-fit ​​member 35 itself to buffer the impact force of the snap-fit, avoiding wear caused by rigid collision between the mounting tube 4 and the connecting sleeve 3. The elastic snap-fit ​​member 35 can adopt a structure such as a rubber protrusion or a silicone protrusion, and the specific material of the elastic snap-fit ​​member 35 is not limited here.

[0055] More specifically, in this embodiment, the mounting tube 4 is provided with two snap-fit ​​holes 41. Correspondingly, each of the opposing inner walls of the connecting cavity 32 is provided with an elastic snap-fit ​​element 35. The elastic snap-fit ​​elements 35 can be fastened into the snap-fit ​​holes 41 one by one, thereby forming a bidirectional symmetrical locking, making the force on the mounting tube 4 more balanced, thereby improving the connection stability between the mounting tube 4 and the connecting sleeve 3, and avoiding the unilateral tilting or rotation of the mounting tube 4 caused by a single snap-fit. It should be noted that the specific number of snap-fit ​​holes 41 and elastic snap-fit ​​elements 35 is not limited, as long as the above-mentioned functions can be achieved.

[0056] In other embodiments, the mounting tube 4 is provided with a flexible snap-fit ​​element 35, and the connecting sleeve 3 is provided with a snap-fit ​​hole 41. When the mounting tube 4 and the connecting sleeve 3 are fitted together, the flexible snap-fit ​​element 35 is fastened to the snap-fit ​​hole 41, thereby achieving a detachable connection between the mounting tube 4 and the connecting sleeve 3. It is understood that the specific location of the snap-fit ​​hole 41 and the flexible snap-fit ​​element 35 is not particularly limited, as long as the above-mentioned functions can be achieved.

[0057] Specifically, in this embodiment, a portion of the edge of the elastic snap-fit ​​member 35 has a hollow structure between it and the connecting sleeve 3. This allows the elastic snap-fit ​​member 35 to extend into the connecting cavity 32 and out of the connecting sleeve 3 under external force, thereby achieving the fastening or release between the elastic snap-fit ​​member 35 and the snap-fit ​​hole 41. The hollow structure provides sufficient deformation space for the elastic snap-fit ​​member 35, ensuring that it can smoothly extend and retract under external force to complete the fastening and release, avoiding insufficient deformation space that prevents the elastic snap-fit ​​member 35 from being fully engaged or disengaged.

[0058] Specifically, the connecting sleeve 3 is provided with a disassembly hole 36, which is opposite to the elastic snap-fit ​​member 35. By providing the disassembly hole 36, an external operating channel can be provided for the elastic snap-fit ​​member 35, so that the tool can be inserted through the disassembly hole 36 to press the elastic snap-fit ​​member 35 to deform and disengage from the snap-fit ​​hole 41, thereby realizing the quick disassembly of the installation tube 4.

[0059] Specifically, the elastic snap-fit ​​component 35 is provided with a guide surface 351 to meet different assembly requirements between the mounting tube 4 and the connecting sleeve 3.

[0060] More specifically, in this embodiment, along the axial direction of the mounting tube 4, the guide surface 351 gradually approaches the axis of the mounting tube 4 in the direction of approaching the connector 2. When the mounting tube 4 is pulled out of the connecting sleeve 3, the guide surface 351 generates an outward force through relative sliding, which can assist the elastic snap-fit ​​35 in deforming and disengaging from the snap-fit ​​hole 41, thereby making it easier for the user to pull the mounting tube 4 out of the connecting sleeve 3 with less effort.

[0061] In other embodiments, along the axial direction of the mounting tube 4, the guide surface 351 gradually moves away from the axis of the mounting tube 4 towards the connector 2, so as to improve the fastening effect between the elastic snap-fit ​​35 and the snap-fit ​​hole 41, thereby improving the connection stability between the mounting tube 4 and the connecting sleeve 3 and preventing them from separating.

[0062] Specifically, the quick-release structure also includes a limiting member 5, which is disposed on the mounting member 1. The limiting member 5 at least partially abuts against the connecting sleeve 3, thereby forming a radial limit on the connecting sleeve 3 and restricting the displacement range of the connecting sleeve 3, thereby improving the relative positional stability of the mounting member 1, the connecting member 2 and the connecting sleeve 3.

[0063] More specifically, in this embodiment, the limiting member 5 includes a semi-circular arc plate, and both the mounting tube 4 and the connecting sleeve 3 are cylindrical structures. By having the inner wall of the semi-circular arc plate fit against part of the outer peripheral wall of the connecting sleeve 3, the cylindrical connecting sleeve 3 can be precisely radially limited, preventing the connecting sleeve 3 from moving radially and detaching under the action of external force. Moreover, the opening end of the semi-circular arc plate is set downward, which can provide sufficient space for the mounting tube 4 to be inserted and removed, while avoiding the accumulation of dust due to the opening facing upward.

[0064] In other embodiments, the limiting member 5 includes a circular arc plate, the inner wall of which can fit more closely to the outer peripheral wall of the connecting sleeve 3, thereby further improving the radial limiting effect on the connecting sleeve 3 and preventing it from shaking.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
