Description

Technical Field

[0001] This utility model relates to the field of assembly and fixing structure technology, and in particular, to a quick assembly and disassembly structure. Background Technology

[0002] Currently, various methods can be used to connect and disassemble equipment, such as threaded fastening, magnetic connections, and pin hinges. While threaded connections (such as screws and nuts) offer high connection strength, the assembly and disassembly process is cumbersome, requiring specialized tools and resulting in low operational efficiency. This is particularly true in applications requiring frequent maintenance or component replacement, significantly increasing time and labor costs. Magnetic quick-release structures offer some ease of operation, but their connection strength is limited by magnetic force, making them prone to accidental detachment under significant external forces or vibrations, resulting in insufficient reliability and difficulty meeting high-strength connection requirements.

[0003] On the other hand, in the field of mechanical equipment, traditional hinged structures typically use a pin and bushing connection. This type of structure often requires specialized equipment such as a sledgehammer or hydraulic jack for disassembly and assembly, making operation extremely inconvenient and prone to damaging components. It cannot adapt to working conditions requiring frequent assembly and disassembly, thus limiting its application in high-efficiency operating environments.

[0004] Furthermore, some existing quick-release structures often sacrifice connection stability and structural strength to achieve rapid assembly and disassembly. For example, some latch-type quick-release mechanisms are prone to increased clearance due to component wear after long-term use, leading to equipment shaking or locking failure, resulting in poor reliability and durability. At the same time, these structures typically have limited applicability and poor compatibility, making them difficult to effectively promote across different types of equipment or cross-scenario applications.

[0005] Therefore, there is an urgent need for a quick-release structure that combines high-strength connection, convenient operation, and good adaptability to resolve the contradiction between connection strength and disassembly efficiency in the existing technology, and to improve the stability and versatility of the structure. Utility Model Content

[0006] This invention provides a quick-assembly and disassembly structure that combines high-strength connection, convenient operation, and good adaptability, thereby solving the technical problem of the contradiction between connection strength and disassembly efficiency in existing quick-assembly structures.

[0007] This utility model provides a quick-assembly and disassembly structure, including a first installation module and a second installation module. The first installation module and the second installation module are connected by a male and female groove. The inlet and / or outlet ends of the male and female grooves are provided with an eccentric pressing structure. The eccentric pressing structure is positioned and connected to the female groove end or male block end of the corresponding end of the male and female grooves, and forces the female groove or male block to move radially eccentrically through eccentric force, thereby realizing a stable connection between the first installation module and the second installation module. The eccentric pressing structure is assembled in a quick-assembly and disassembly type by an eccentric mechanism.

[0008] Furthermore, the female groove of the male and female grooves is arranged on the first mounting module, and the male block of the male and female grooves is arranged on the second mounting module. The eccentric pressing structure includes a fixed plate, a movable plate, a pin assembly, and an eccentric mechanism. The fixed plate is arranged on the first mounting module and is located on the side of the male and female grooves. The first end of the movable plate is connected to the fixed plate through the eccentric mechanism, and the second end of the movable plate is positioned at the end of the male block through the pin assembly.

[0009] Furthermore, the female groove of the male and female grooves is arranged on the second mounting module, and the male block of the male and female grooves is arranged on the first mounting module. The eccentric pressing structure includes a fixed plate, a movable plate, a pin assembly, and an eccentric mechanism. The fixed plate is arranged on the first mounting module and is located on the side of the male and female grooves. The first end of the movable plate is connected to the fixed plate through the eccentric mechanism, and the second end of the movable plate is positioned at the end of the female groove through the pin assembly.

[0010] Furthermore, the pin assembly includes a pin and a pin hole; at least two sets of pin assemblies are arranged at intervals.

[0011] Furthermore, the eccentric mechanism includes a stud, a first stud hole, and a second stud hole. The first stud hole is located in the fixed plate, and the second stud hole is located in the movable plate. The first vertical distance between the first stud hole and the pin hole is greater than or less than the second vertical distance between the second stud hole and the pin hole, and they are combined to form an eccentric structure. By assembling the stud into the first stud hole and the second stud hole, a relative eccentric force is generated between the female groove and the male block via the pin assembly.

[0012] Furthermore, the distance difference between the first vertical distance and the second vertical distance is 0.1 mm to 5 mm; or the distance difference between the second vertical distance and the first vertical distance is 0.1 mm to 5 mm.

[0013] Furthermore, the stud is provided with ball bearings, and multiple ball bearings are evenly arranged around the circumference of the stud. The end of the second stud hole away from the movable plate is provided with a groove, and the ball bearings are arranged in a one-to-one correspondence with the groove. The stud passes through the first stud hole and the second stud hole and matches and connects the ball bearings with the groove, thereby realizing the locking of the stud.

[0014] Furthermore, the lower side of the first mounting module is connected to the first mounting module through multiple sets of male and female grooves, and each set of male and female grooves is provided with a set of eccentric pressing structures.

[0015] Furthermore, the lower side of the first mounting module is connected to the first mounting module through two sets of male and female grooves, and each set of male and female grooves is provided with a set of eccentric pressing structures; the male and female grooves and the eccentric pressing structures are symmetrically arranged at both ends of the first mounting module.

[0016] Furthermore, one end of the female groove in the male and female grooves is closed by an end plate.

[0017] This utility model has the following beneficial effects:

[0018] 1. Effectively improves connection strength and impact resistance: The plug-in fit of the male and female slots constitutes the main load-bearing structure, providing basic mechanical connection strength; the added eccentric pressing structure generates a continuous radial eccentric force, forcing the male block and female slot to form a tight press and increasing friction, thereby significantly enhancing the connection point's ability to resist axial pull-out and lateral shear force, solving the problems of insufficient connection strength and easy separation by external force in traditional magnetic attraction and other methods.

[0019] 2. Significantly improves connection stability and reliability: The eccentric force generated by the eccentric mechanism has adaptive characteristics, which can automatically compensate for the fit clearance caused by manufacturing tolerances or wear during long-term use. This avoids problems such as equipment shaking, abnormal noise and locking failure caused by increased clearance in traditional pin structures, ensuring the stability of the connection under various working conditions and the reliability over a long life cycle.

[0020] 3. Achieve an efficient and convenient operating experience: The combination of male and female grooves and eccentric pressing structure combines simple axial insertion with quick eccentric snap-fit ​​operation, making the entire assembly and disassembly process smooth and intuitive. It can usually be completed without the aid of any tools, which greatly simplifies the operation steps and shortens the assembly and disassembly time. It perfectly meets the pursuit of efficiency in application scenarios that require frequent maintenance, replacement or adjustment.

[0021] 4. Enhanced structural versatility and adaptability: As a basic mechanical connection interface, the male and female grooves can be flexibly designed in terms of form (such as dovetail grooves, T-grooves, C-grooves, etc.) and size according to specific load-bearing requirements, and have a wide range of applications; the eccentric pressing structure, as a modularly addable functional unit, can be arranged at key positions in the insertion path, such as the assembly inlet or outlet of the male and female grooves, and can be flexibly adapted to different types and specifications of products, with good design compatibility and application potential.

Detailed Implementation

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the quick-assembly structure of this embodiment includes a first installation module 100 and a second installation module 200. The first installation module 100 and the second installation module 200 are connected by a male and female groove 300. An eccentric pressing structure 400 is provided at the insertion inlet and / or outlet end of the male and female groove 300. The eccentric pressing structure 400 is positioned and connected to the end of the female groove 301 or the end of the male block 302 at the corresponding end of the male and female groove 300. The eccentric force forces the female groove 301 or the male block 302 to move radially eccentrically, thereby achieving a stable connection between the first installation module 100 and the second installation module 200. The eccentric pressing structure 400 is assembled in a quick-assembly snap-fit ​​manner through an eccentric mechanism 404. This utility model's quick-assembly and disassembly structure uses the insertion and mating of male and female grooves 300 to form the main load-bearing structure, providing basic mechanical connection strength. The added eccentric pressing structure 400 generates a continuous radial eccentric force, forcing the male block 302 and female groove 301 to form a tight press and increasing friction, thereby significantly enhancing the connection point's ability to resist axial pull-out and lateral shear force. This solves the problems of insufficient connection strength and susceptibility to external force detachment in traditional magnetic attraction methods. The eccentric force generated by the eccentric mechanism 404 has adaptive characteristics, automatically compensating for the fit clearance caused by manufacturing tolerances or long-term wear. This avoids problems such as equipment shaking, abnormal noise, and locking failure caused by increased clearance in traditional pin structures, ensuring the stability of the connection under various working conditions and its reliability over a long lifespan. The combined structure of the male and female grooves 300 and the eccentric pressing mechanism 400 integrates simple axial insertion with rapid eccentric snap-fit ​​operation, making the entire assembly and disassembly process smooth and intuitive. It can usually be completed without any tools, greatly simplifying the operation steps and shortening the assembly and disassembly time. This perfectly meets the efficiency requirements of applications that require frequent maintenance, replacement, or adjustment. The male and female grooves 300, as a basic mechanical connection interface, can be flexibly designed in terms of form (such as dovetail grooves, T-grooves, C-grooves, etc.) and size according to specific load-bearing requirements, resulting in a wide range of applications. The eccentric pressing mechanism 400, as a modularly addable functional unit, can be placed at key locations in the insertion path, such as the assembly inlet or outlet of the male and female grooves 300. It can flexibly adapt to different types and specifications of products, exhibiting good design compatibility and application potential. By combining and coordinating the male and female grooves 300 and the eccentric pressing structure 400, multiple requirements such as high connection strength, good stability, convenient operation and strong adaptability can be met at the same time. This comprehensively solves the contradiction between strength and convenience, stability and wear, and versatility and specialization in the existing technology, and provides an efficient, reliable and universal quick disassembly and assembly solution.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the female groove 301 of the male and female groove 300 is arranged on the first mounting module 100, and the male block 302 of the male and female groove 300 is arranged on the second mounting module 200. The eccentric pressing structure 400 includes a fixed plate 401, a movable plate 402, a pin assembly 403, and an eccentric mechanism 404. The fixed plate 401 is arranged on the first mounting module 100 and is located on the side of the male and female groove 300. The first end of the movable plate 402 is connected to the fixed plate 401 through the eccentric mechanism 404, and the second end of the movable plate 402 is positioned at the end of the male block 302 through the pin assembly 403. By positioning the second end of the movable plate 402 to the end of the male block 302 via the pin assembly 403, and connecting the first end of the movable plate 402 to the fixed plate 401 fixed to the side of the male and female grooves 300 via the eccentric mechanism 404, the movable plate 402 can act as a single lever when the eccentric mechanism 404 is operated. This effectively converts the eccentric motion into a continuous and stable radial clamping force on the end of the male block 302. The radial clamping force acts directly on the root of the mating joint, effectively eliminating the mating gap between the male block 302 and the female groove 301, preventing shaking or abnormal noise when the connection is under force, and significantly improving the rigidity and stability of the connection. The fixed plate 401 is fixed to the first mounting module 100, providing a stable mounting base for the entire eccentric pressing structure 400. The pin assembly 403 hinges the movable plate 402 to the end of the male block 302, ensuring that the clamping force is accurate and reliable. The force is transferred to the common block 302, avoiding force dispersion or unexpected deformation of structural components, and enhancing the durability and reliability of the structure under repeated disassembly and long-term use. Users only need to operate the eccentric mechanism 404 (such as rotating the eccentric cam or pulling the handle) to easily drive the movable plate 402 through the lever principle, thereby quickly pressing or releasing the common block 302. The entire operation process is labor-saving, has a short stroke, and simple action, without the need for additional tools, achieving true quick disassembly and assembly, greatly improving maintenance efficiency and operating experience. The eccentric pressing structure 400 is designed as an independent functional module composed of a fixed plate 401, a movable plate 402, a pin assembly 403, and an eccentric mechanism 404, and is fixed to the mounting module. This makes the quick-release unit itself easy to manufacture, install, and replace. If a component is damaged, it can be replaced specifically without scrapping the entire mounting module, reducing maintenance costs.

[0035] In this embodiment, the female groove 301 of the male and female groove 300 is arranged on the second mounting module 200, and the male block 302 of the male and female groove 300 is arranged on the first mounting module 100. The eccentric pressing structure 400 includes a fixed plate 401, a movable plate 402, a pin assembly 403, and an eccentric mechanism 404. The fixed plate 401 is arranged on the first mounting module 100 and is located on the side of the male and female groove 300. The first end of the movable plate 402 is connected to the fixed plate 401 through the eccentric mechanism 404, and the second end of the movable plate 402 is positioned at the end of the male and female groove 300 through the pin assembly 403. The second end of the movable plate 402 is positioned at the end of the male and female grooves 300 via the pin assembly 403, and the first end of the movable plate 402 is connected to the fixed plate 401, which is fixed to the male block 302 on the side of the first mounting module 100, via the eccentric mechanism 404. When the eccentric mechanism 404 is operated, the movable plate 402 acts as a lever, converting the eccentric motion into a continuous and stable radial clamping force on the end of the male and female grooves 300. This radial clamping force acts directly on the root of the male and female grooves 300, effectively constraining the radial deformation or displacement of the male and female grooves 300, thereby eliminating the fitting gap between the male block 302 and the female groove 301, preventing the connection from shaking under force, and significantly improving the rigidity and stability of the connection. The fixed plate 401 is fixed to the first mounting module 100, providing a stable base for the entire eccentric pressing structure 400. The pin assembly 403 hinges the movable plate 402 to the end of the male and female grooves 300, ensuring that... The clamping force can be applied precisely and reliably directly to the male and female grooves 300, which need to be constrained, making the force transmission path more direct and clear, and enhancing the durability and reliability of the structure under repeated disassembly and long-term load. Users only need to operate the eccentric mechanism 404 (such as rotating the eccentric cam or pulling the handle) to easily drive the movable plate 402 through the lever principle, thereby quickly clamping or loosening the ends of the male and female grooves 300. The entire operation process is labor-saving, has a short stroke, and simple action, requiring no additional tools, achieving truly rapid disassembly and assembly, and greatly improving maintenance efficiency and operating experience. It provides an innovative way to actively constrain and lock the male and female grooves 300 in the plug-in fit. By directly applying a controllable radial force to the ends of the male and female grooves 300, it can effectively compensate for tolerances and suppress loosening caused by vibration, providing a direct and efficient technical means to solve the stability problem in the connection of the male and female grooves 300.

[0036] like Figure 5As shown, in this embodiment, the pin assembly 403 includes pins 4031 and pin holes 4032; at least two sets of pin assemblies 403 are arranged at intervals. By setting at least two sets of spaced-apart pins 4031 cooperating with pin holes 4032, a multi-point positioning constraint is formed between the end of the male and female groove 300 and the second end of the movable plate 402. This can effectively resist the torsion or off-center load that may occur between the movable plate 402 and the male block 302 when the movable plate 402 is under force, and prevent the movable plate 402 from warping or deforming unexpectedly. This ensures that the clamping force generated by the eccentric mechanism 404 can be transmitted to the end of the male and female groove 300 more evenly and stably, thereby greatly improving the overall rigidity and reliability of the connection. Under long-term repeated clamping and loosening operations, the connection point of a single-point pin connection is prone to wear or deformation due to stress concentration. However, by using two or more sets of spaced-apart pin assemblies 403, the force can be distributed to multiple connections. At the point of view, the contact stress at a single pin hole 4032 is significantly reduced, wear is reduced, and the service life of the movable plate 402, the ends of the male and female grooves 300, and the pin assembly 403 itself is extended, thus improving the durability of the entire pressing structure. Multiple sets of pin assemblies 403 together form a more stable hinge axis or constraint interface, making the movement of the movable plate 402 more stable and precise when it rotates around the axis under the drive of the eccentric mechanism 404. This avoids the backlash and wobbling that may exist in single-point hinges, ensures the certainty of the direction of the clamping force, and makes the force transmission more efficient and reliable. The spaced multi-point constraints can form a more effective enclosure and restriction on the ends of the male and female grooves 300, thereby further ensuring the tightness and stability of the insertion fit between the male block 302 and the female groove 301.

[0037] like Figure 5As shown, in this embodiment, the eccentric mechanism 404 includes a stud 4041, a first stud hole 4042, and a second stud hole 4043. The first stud hole 4042 is formed in the fixed plate 401, and the second stud hole 4043 is formed in the movable plate 402. The first vertical distance between the first stud hole 4042 and the pin hole 4042 is greater than or less than the second vertical distance between the second stud hole 4043 and the pin hole 4032, and they are combined to form an eccentric structure. By assembling the stud 4041 into the first stud hole 4042 and the second stud hole 4043, a relative eccentric force is generated between the female groove 301 and the male block 302 via the pin assembly 403. By precisely setting the first vertical distance between the first bolt hole 4042 and the pin hole 4032 to be unequal to the second vertical distance between the second bolt hole 4043 and the pin hole 4032, a natural eccentric lever mechanism is formed between the fixed plate 401, the movable plate 402, and the pin assembly 403. When the bolt 4041 is simultaneously inserted into the first bolt hole 4042 and the second bolt hole 4043, due to the difference in the center distance between the two holes and the pin hole 4032, the movable plate 402 is forced into an eccentric pre-tightened position. When the bolt 4041 is rotated or driven, the eccentric mechanism 404 can effectively amplify the small operating force and convert it into a significant radial clamping force acting on the end of the male and female grooves 300, achieving labor-saving and efficient locking. The eccentric mechanism 404 can pass the dead point or reach the self-locking position in the clamped state. Once the clamping is complete, the normal force generated by the eccentric mechanism 404 and the resulting friction will form a stable mechanical balance, effectively resisting vibration and impact, preventing accidental loosening of the connection, and ensuring the long-term stability of the connection. The eccentric mechanism 404 consists only of a bolt 4041 and two bolt holes opened on the fixed plate 401 and the movable plate 402, without the need for complex additional parts. The simple structure means lower manufacturing costs, higher reliability, and fewer points of failure. All moving parts are confined to a limited space, making the entire eccentric clamping structure 400 very compact. Users can easily drive the entire eccentric lever mechanism by rotating or moving the bolt 4041 (e.g., using a handle or wrench) to quickly complete the clamping or loosening action. This operation is intuitive, labor-saving, and has a short stroke, perfectly meeting the functional requirements of quick assembly and disassembly.

[0038] like Figure 2As shown, in this embodiment, the distance difference between the first vertical distance and the second vertical distance is 0.1 mm to 5 mm; or the distance difference between the second vertical distance and the first vertical distance is 0.1 mm to 5 mm. Limiting the eccentricity (i.e., the distance difference) to the range of 0.1 mm to 5 mm ensures that when the stud 4041 is rotated, the movable plate 402 can generate a significant and controllable radial displacement, balancing the operating force and the clamping effect. Within this range of eccentricity, the user can feel a clear change in hand feel or torque when locking or loosening the stud 4041 by rotating it. The operation is effortless and provides clear feedback, avoiding the problems of no feeling due to too short a stroke or time-consuming and laborious work due to too long a stroke. This improves the intuitiveness of operation and user experience, meeting the core requirement of ease of operation for quick-assembly and disassembly structures. The clamping stroke range of 0.1 mm to 5 mm effectively covers... The 300mm male-female groove mating mechanism addresses common dimensional tolerances and wear that may occur after long-term use of components. It ensures that even with tolerances or slight wear, the eccentric mechanism 404 can still generate sufficient clamping force through its stroke margin to eliminate gaps, guaranteeing connection stability and reliability, and extending product lifespan. This range of eccentricity design allows for sufficient clamping force while minimizing the swing space required for the movable plate 402, contributing to a compact structure and easy integration into products. Simultaneously, it avoids the risk of accidental interference between the movable plate 402 and surrounding structures due to excessive stroke, improving safety. If this value is too small, such as less than 0.1mm, the clamping stroke will be too short, potentially failing to effectively compensate for the mating gap, resulting in insufficient clamping force and poor locking effect. If this value is too large, such as greater than 5mm, it may cause excessive displacement of the movable plate 402, drastically increasing the required operating force, making operation difficult, and potentially causing structural interference or damage. Optionally, at least one of the pin hole 4032, the first stud hole 4042, and the second stud hole 4043 is provided with an elastic protective bushing; the eccentricity (i.e., the distance difference) can be finely adjusted by the elastic protective bushing (by replacing different elastic protective bushings), while also playing a certain role in buffering and protection, and preventing structural damage caused by long-term action on the hole.

[0039] like Figure 5 and Figure 6As shown, in this embodiment, the stud of the bolt 4041 is provided with ball bearings 4044, and multiple ball bearings 4044 are evenly arranged along the circumference of the stud. The end of the second bolt hole 4043 away from the movable plate 402 is provided with a groove 4045, and the ball bearings 4044 and the groove 4045 are arranged in a one-to-one correspondence. The bolt 4041 passes through the first bolt hole 4042 and the second bolt hole 4043 and matches and connects the ball bearings 4044 with the groove 4045, thereby realizing the locking of the bolt 4041. When the stud 4041 passes through the hole and the ball 4044 aligns with the groove 4045, the ball 4044 engages in the corresponding groove 4045, providing a clear positioning feel and mechanical interlock. This offers a quick locking mechanism without additional tools; simply pushing the stud to the predetermined position automatically locks it, effectively preventing the stud 4041 from accidentally rotating or loosening under vibration or external force, ensuring the reliability of the eccentric mechanism 404's locking state. As a rolling element, the ball 4044's contact with the groove 4045 is rolling friction, which has a much lower frictional resistance than the sliding friction between the stud and the hole wall. This makes inserting and removing the stud 4041 easier and smoother, while significantly reducing the contact area between the stud 4041 and the stud hole. Wear between the first pin hole 4042 and the second pin hole 4043 extends the service life of the pin 4041, the movable plate 402, and the fixed plate 401, improving the overall durability of the mechanism. When the ball bearing 4044 falls into the groove 4045, it produces a clear sound or tactile feedback, clearly indicating to the operator that locking is complete. This positive feedback makes operation more intuitive and reliable, improving the user experience and avoiding repetitive operations or checks due to uncertain locking status, further demonstrating the convenience of quick assembly and disassembly. Once the ball bearing 4044 locks with the groove 4045, a stable relative positional relationship is formed between the pin 4041, the movable plate 402, and the fixed plate 401, ensuring that the eccentricity remains constant. This prevents the preload from loosening due to slight rotation of the pin 4041 caused by vibration or impact during equipment operation, thus maintaining a persistent clamping force and ensuring the stability of the connection.

[0040] like Figure 1 , Figure 5 and Figure 6As shown, in this embodiment, the lower side of the first mounting module 100 is connected to the first mounting module 100 via multiple sets of male and female grooves 300. Each set of male and female grooves 300 is provided with a set of eccentric pressing structures 400. Through the connection of multiple sets of male and female grooves 300, multiple parallel force transmission paths are formed between the first mounting module 100 and the second mounting module 200, distributing the load to each connection point. This greatly enhances the overall rigidity and stability of the connection structure when subjected to complex loads (such as bending moment and torque), avoids stress concentration or structural deformation that may occur with single-point connection, and can meet the application requirements of higher strength and heavier load. Each set of male and female grooves 300 is provided with a set of eccentric pressing structures 400, so that the clamping force can be evenly distributed on the entire connection interface, ensuring that the fit gap between the male block 302 and the female groove 301 is effectively eliminated at multiple points simultaneously, avoiding warping or local stress on the connection surface that may be caused by single-point clamping, thereby obtaining a smoother and more stable connection effect. In applications requiring sealing, uniform pressure distribution also helps improve the compression uniformity of the seals and enhances sealing reliability. A multi-connection layout (usually symmetrical or uniformly distributed) effectively resists off-center loads or impacts from different directions, preventing loosening or damage to the connection structure under asymmetrical forces. The combined operation of multiple eccentric anti-loosening mechanisms 400 significantly enhances the entire connection system's anti-loosening capability under vibration, improving equipment reliability and safety. Integrating multiple quick-release units onto a single modular interface allows users to quickly lock or release the entire large interface simply by operating multiple eccentric mechanisms 404 sequentially or simultaneously, greatly improving the efficiency of assembling and disassembling large components, modules, or complete equipment. This is particularly suitable for large equipment requiring frequent maintenance, replacement, or transportation.

[0041] like Figure 1 , Figure 5 and Figure 6As shown, in this embodiment, the lower side of the first installation module 100 is connected to the first installation module 100 through two sets of male and female grooves 300. Each set of male and female grooves 300 is provided with a set of eccentric pressing structures 400. The male and female grooves 300 and the eccentric pressing structures 400 are symmetrically arranged at both ends of the first installation module 100. Two sets of male and female grooves 300 and corresponding eccentric pressing structures 400 are symmetrically arranged at both ends of the first mounting module 100. This ensures that the clamping force and constraint force are symmetrically distributed with the center of the connection interface as the reference. This effectively resists bending moments or torques from different directions, preventing stress concentration, warping, or loosening on one side of the connection structure when subjected to asymmetrical loads, and greatly enhancing the stability and reliability of the overall connection. The symmetrically arranged eccentric pressing structures 400 can apply clamping force synchronously and uniformly from both ends, ensuring that the mating gap between the male block 302 and the female groove 301 is uniformly eliminated along the entire contact surface. This avoids twisting or local wear of the connection surface that may be caused by unilateral clamping, making the connection interface uniformly stressed and improving the fatigue life and load-bearing capacity of the structure. The two sets of symmetrical male and female grooves 300 are plugged in to form two clear and symmetrical force transmissions. The path effectively transfers the load from the first mounting module 100 to the second mounting module 200, significantly enhancing the overall rigidity of the interface and reducing the relative displacement or deformation of the connection parts under load. This is suitable for applications requiring high structural rigidity. The symmetrical layout allows the operator to quickly and evenly lock or unlock the entire interface by operating the eccentric mechanisms 404 at both ends sequentially or simultaneously (e.g., by simultaneously pulling both handles). This simplifies the operation steps, avoids structural internal stress that may result from asymmetrical locking, and further improves the efficiency and user experience of assembly and disassembly. The symmetrical layout provides excellent centering guidance. During the insertion process, the male and female slots 300 at both ends can jointly guide the first mounting module 100 and the second mounting module 200 to accurately align, reducing adjustment time during installation and lowering the possibility of misoperation.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, in this embodiment, one end of the female groove 301 of the male and female grooves 300 is closed by the end plate 303. The end plate 303 forms a rigid groove end of the female groove 301. When the male block 302 is inserted into the female groove 301 and reaches the predetermined position, its end will contact the inner surface of the end plate 303, thereby being precisely restricted to the design position. This provides a clear axial positioning reference for the entire insertion and mating, preventing the male block 302 from affecting the connection accuracy and the normal operation of the eccentric pressing structure 400 due to over-insertion or under-insertion, and ensuring consistency in each disassembly and assembly. The end plate 303 closes one end of the female groove 301, which is equivalent to providing an additional support surface for the female groove 301, enhancing the structural rigidity and torsional and bending resistance of the female groove 301 (especially the open end), reducing the risk of deformation, flaring, or damage of the opening of the female groove 301 due to force during insertion and extraction or when bearing load, thereby improving the structural rigidity of the female groove 301. The durability of the end plate 301 itself and the reliability of the connection; the closed structure of the end plate 303 to a certain extent blocks the path of dust, debris and other contaminants from the end of the female groove 301 into the groove, which helps to keep the mating surfaces of the male block 302 and the female groove 301 clean, reducing wear, jamming or decreased connection accuracy caused by contamination, and is particularly suitable for harsh working conditions such as outdoor or dusty environments; when the eccentric pressing structure 400 (such as through the movable plate 402 and the pin assembly 403 at the second end) acts on the closed end of the female groove 301, the end plate 303 can provide a stable force-bearing base for it, ensuring that the pressing force can be effectively transmitted to the entire female groove 301 structure through the end plate 303, avoiding the direct application of force to the weak groove wall or opening, optimizing the force transmission path and improving the pressing efficiency.

[0043] In implementation, a quick-assembly / disassembly structure achieves initial alignment and load-bearing through the insertion and mating of male and female grooves 300, and utilizes an eccentric pressing structure 400 to generate radial eccentric force to eliminate mating gaps and enhance connection strength and stability. The quick-assembly / disassembly structure mainly includes a first mounting module 100, a second mounting module 200, male and female grooves 300, and an eccentric pressing structure 400. The eccentric pressing structure 400 consists of a fixed plate 401, a movable plate 402, a pin assembly 403, and an eccentric mechanism 404. By operating the eccentric mechanism 404 (such as a stud 4041), the movable plate 402 is driven, forcing the end of the male block 302 or the female groove 301 to move radially, achieving tight clamping.

[0044] I. Rapid Assembly Process

[0045] 1. Alignment and insertion: Align the male block 302 of the first mounting module 100 with the female groove 301 of the second mounting module 200, and insert it axially until the end of the male block 302 contacts the closed end plate 303 of the female groove 301, thus completing the initial positioning and mechanical connection.

[0046] 2. Drive eccentric mechanism 404: Operate eccentric mechanism 404 (such as rotating pin 4041), and through the principle of eccentric lever, make movable plate 402 rotate around pin assembly 403, thereby applying radial clamping force to the end of female groove 301 or male block 302.

[0047] 3. Locking and Confirmation: When the ball 4044 on the stud 4041 falls into the groove 4045 and produces a sound or tactile feedback, it indicates that the eccentric mechanism 404 has been locked, the clamping force has reached the preset value, and the connection is in a stable locked state.

[0048] II. Quick Disassembly Process

[0049] 1. Release eccentric mechanism 404: Reverse the operation of eccentric mechanism 404 (e.g., reverse the rotation of stud 4041) to disengage ball 4044 from groove 4045 and release the locked state.

[0050] 2. Loosen the clamping force: Continue to operate the eccentric mechanism 404 to return the movable plate 402 to its original position. The radial clamping force is gradually released, and the tight fit between the male block 302 and the female groove 301 becomes loose.

[0051] 3. Axial pull-out: Easily pull out the first mounting module 100 along the axial direction to complete the disassembly.

[0052] The technical advantages of this invention's quick-assembly and disassembly structure are as follows:

[0053] 1. High efficiency and convenience: The plug-in connection with eccentric clamping makes operation simple, labor-saving, and tool-free.

[0054] 2. Connection reliability: Eccentric force adaptive compensation gap, vibration resistant and anti-loosening.

[0055] 3. High adaptability: It can meet the requirements of high load and high rigidity through multiple sets of symmetrical layouts.
