[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] A quick-lock component for rapid disassembly of a shelf, characterized in that it includes a quick-lock rotating shaft 1 and a quick-lock wrench 6. The quick-lock rotating shaft 1 is connected to the quick-lock wrench 6 through a connecting piece, and a quick-lock pressure plate 9 is provided below the quick-lock wrench 6;

[0021] The quick-lock pressure plate 9 is placed on the quick-lock seat 4, and a quick-lock rubber spring 3 is provided below the quick-lock seat 4;

[0022] A hole is opened in the center of the quick-lock rotating shaft 1, and a quick-lock positioning spring 7 and a steel ball 8 are installed in the hole.

[0023] Under the elastic force of the spring, the steel ball 8 can quickly enter or exit the semi-circular hole of the quick-lock seat 4. This mechanism significantly speeds up the locking and unlocking speeds, thereby greatly improving the operation efficiency. In industrial applications that require rapid assembly or disassembly, such as in automated production lines or tool replacement processes, this high-speed response characteristic can be translated into a significant increase in production efficiency.

[0024] The precise matching of the steel ball 8 and the semi-circular hole not only provides an efficient locking method for the quick-lock system, but also their cooperation constitutes a reliable additional locking mechanism. This mechanism ensures that even when subjected to unexpected external forces or vibrations, the connection can remain stable and will not unlock accidentally, thereby enhancing the self-locking property of the connection. This is particularly important in applications where safety is crucial, such as in construction machinery, aerospace, or medical devices, where any accidental unlocking may lead to serious consequences.

[0025] Due to the precise matching between the steel ball 8 of the quick-lock rotating shaft 1 and the semi-circular hole of the quick-lock seat 4, this design not only ensures the accuracy of the initial assembly, but also guarantees that after multiple disassembly and reassembly, the same level of precision and repeat positioning accuracy can still be maintained. This is crucial for applications that require frequent disassembly and assembly. Precise repeat positioning can ensure the rapid and accurate assembly of components, reducing assembly errors and the time for additional adjustments.

[0026] The designs of the quick-lock rotating shaft 1 and the quick-lock seat 4 are highly flexible and can be customized according to different application requirements to adapt to different loads and operating environments. For example, the stiffness of the spring or the size of the steel ball 8 can be changed to adapt to different load requirements, or the size of the semi-circular hole can be adjusted to accommodate rotating shafts of different diameters. This design flexibility enables the quick-lock system to be widely applied in various industrial and engineering fields, including manufacturing, construction, and transportation industries, etc.

[0027] Finally, the mating design of the quick-lock rotating shaft 1 and the quick-lock seat 4 also brings benefits in terms of maintenance. Due to their simple structure and easy disassembly, it becomes more convenient and faster to maintain and replace components. This means that during regular inspections or when components fail, maintenance work can be completed more quickly, which helps reduce maintenance costs and downtime. In modern industrial production, where high efficiency and high reliability are pursued, this easy-to-maintain feature is crucial.

[0028] The quick-lock rotating shaft 1 and the quick-lock wrench 6 are connected by a rivet 5, and the connection part of the quick-lock wrench 6 is a cam. The rivet 5 connection is convenient and fast, and the cam mechanism allows the quick-lock wrench 6 to be quickly locked and unlocked, improving the operation efficiency, which is especially suitable for occasions that require frequent installation and disassembly.

[0029] As a traditional connection method, the rivet 5 still plays an important role in modern industry, especially in occasions that require high-strength connections. In the connection between the quick-lock wrench 6 and the quick-lock rotating shaft 1, the use of the rivet 5 provides a very stable and reliable connection method. This connection can not only withstand repeated mechanical stresses but also resist external forces generated by temperature changes, vibrations, or impacts, thus ensuring the safety and durability of the entire quick-lock assembly under various usage conditions.

[0030] The introduction of the cam mechanism makes the operation of the quick-lock wrench 6 more efficient and fast. Through the carefully designed cam profile, the quick-lock wrench 6 can achieve precise positioning and quick locking and unlocking, enabling the operator to complete complex connection tasks with simple rotation or pressing actions. This simplified operation not only improves work efficiency but also reduces the complexity of the operation, making it easy for non-professionals to get started. It is especially suitable for occasions that require frequent installation and disassembly operations, such as rapid die change on the production line, equipment maintenance and repair, etc.

[0031] The simplicity and reliability of the rivet 5 connection also mean that its maintenance requirements are relatively low. Compared with traditional bolt connections, due to the one-time forming characteristic of the rivet 5, it does not require frequent inspection of the fastening state, thus reducing the maintenance workload. Regular inspections and lubrication can ensure that the rivet 5 connection remains in good working condition and extend its service life. This low-maintenance feature not only reduces the long-term operating costs but also improves the economic efficiency of the entire quick-lock assembly.

[0032] Generally speaking, the design combining the rivet 5 and the cam mechanism provides a strong, efficient, and low-maintenance connection solution for the quick-lock assembly, which is suitable for a variety of industrial applications, thus improving production efficiency and safety.

[0033] The quick-lock rotating shaft 1 passes through the centers of the quick-lock pressure plate 9 and the quick-lock seat 4. The design of central alignment simplifies the installation process, enabling the quick-lock pressure plate 9 and the quick-lock seat 4 to be precisely aligned, reducing the errors during assembly. The precise installation and uniform force distribution work together to improve the reliability of the quick-lock assembly. In critical applications, such as safety-related equipment or high-precision instruments, this reliability is indispensable as it ensures the stable operation of the equipment under various conditions.

[0034] Due to the central symmetry design enhancing durability and reliability, the need for maintenance is also reduced. This means that both maintenance costs and downtime can be effectively controlled, which is a significant advantage for industrial environments aiming for high efficiency and low-cost operation.

[0035] The central symmetry design also provides greater flexibility for designers, allowing them to adjust the design of the quick-lock assembly according to specific application requirements, such as adding or removing components, changing materials or dimensions, to meet specific performance requirements.

[0036] In summary, the central symmetry design of the quick-lock rotating shaft 1 not only provides stability and durability in structure, but also brings significant advantages in installation and maintenance. These advantages make this design very popular in various industrial and engineering applications.

[0037] The cross-section of the quick-lock seat 4 is an inverted L shape, with extended reinforcing ribs. One end of the quick-lock seat 4 connected to the quick-lock pressure plate 9 is provided with a groove. The inverted L-shaped cross-section provides a large support area, making the quick-lock seat 4 more stable when subjected to vertical and horizontal forces, reducing the possibility of shaking and displacement. The groove can be used as a positioning mark during assembly, making the assembly process faster and simpler, and improving production efficiency. The L-shaped cross-section of the quick-lock seat 4 is also provided with unique holes for connection with the lock head during installation.

[0038] The inverted L-shaped cross-section resembles an inverted letter "L", and this shape is widely regarded as a strong and stable structural form in engineering. The reinforcing ribs further enhance the mechanical strength of the quick-lock seat 4, enabling it to withstand greater loads while resisting bending and torsional forces.

[0039] One end of the quick-lock seat 4 connected to the quick-lock pressure plate 9 is provided with a groove. This design can serve as a guiding feature to ensure that the quick-lock pressure plate 9 can be correctly and quickly positioned on the quick-lock seat 4, simplifying the assembly process. The presence of the groove makes the installation of the quick-lock pressure plate 9 faster and more accurate, reducing the adjustment time during assembly and improving the overall assembly efficiency. The groove can cooperate with specific components on the quick-lock pressure plate 9 to provide an additional locking mechanism, enhancing the stability and security of the connection. Since the connection between the quick-lock seat 4 and the quick-lock pressure plate 9 is achieved through the mutual cooperation of the groove and the flange, it can be quickly disassembled and reassembled when maintenance or component replacement is required.

[0040] In summary, the design of the inverted L-shaped cross-section and the extended reinforcing ribs of the quick-lock seat 4, as well as the groove at the connecting end with the quick-lock pressure plate 9, jointly provide a quick-lock system with stable structure, easy installation, durability and strong adaptability.

[0041] The cross-section of the quick-lock rubber spring 3 is designed in a cam shape. This design can provide a self-locking mechanism after the spring is compressed, enabling the spring to maintain its compressed state at a certain rotation angle. The advantage of this self-locking mechanism is that it can ensure the stability of the quick-lock assembly in the locked state, preventing unlocking caused by accidental collision or vibration, thus improving the safety and reliability during use. For example, in the QSCA quick shaft locking device (pneumatic type), it locks through spring pressure and releases through pneumatic action, which can avoid the decrease of clamping force due to air leakage, demonstrating the advantages of the cam shape in practical applications.

[0042] In addition, the cross-section of the cam shape can also, through its unique geometric shape, make the spring return to its original state after the spring is released, which helps to maintain the locked state of the quick-lock assembly and prevent accidental unlocking. This design is particularly useful in applications that require frequent quick locking and unlocking, such as on automated production lines, where it can improve production efficiency and reduce downtime.

[0043] In mechanical design, a cam mechanism can convert rotational motion into linear motion, and this conversion is the key to achieving the self-locking function. The cam shape design enables the spring to precisely control the motion during compression and release, ensuring the accuracy and repeatability of the operation. This ability of precise control is crucial for many precision machinery and automated equipment.

[0044] In summary, the cam-shaped cross-section design of the quick-lock rubber spring 3 provides an effective self-locking mechanism, which not only enhances the stability and security of the quick-lock assembly, but also improves the efficiency and accuracy of the operation.

[0045] Below the hole opened in the quick-lock rotating shaft 1, there is a groove, in which an O-ring 2 is installed for sealing. The bottom of the quick-lock rotating shaft 1 is also provided with a hole. The quick-lock rotating shaft 1 is provided with a step that matches the quick-lock seat 4. O-ring sealing is a very effective sealing method. It can prevent the leakage of liquid or gas and ensure the sealing performance between connecting components. This kind of sealing is crucial for preventing pollutants from entering and maintaining the cleanliness of the internal environment, especially in applications that require waterproof or dustproof.

[0046] The groove design of the quick-lock rotating shaft 1 and the cooperation of the O-ring 2 provide a stable sealing interface, which helps to maintain stability when the rotating shaft bears dynamic loads and reduces the risk of failure caused by poor sealing. In particular, at both ends of the bottom of the quick-lock rotating shaft 1, there are extended reinforcing ribs, and small holes are also provided on the reinforcing ribs, which match the lock head.

[0047] The bottom hole and step design of the quick-lock rotating shaft 1 make the connection with the quick-lock seat 4 more intuitive and simple. This design simplifies the assembly process, makes installation and maintenance faster, and thus improves work efficiency.

[0048] The step design ensures the precise alignment between the quick-lock rotating shaft 1 and the quick-lock seat 4, which is crucial for ensuring the consistency and reliability of the connection. Precise alignment helps to reduce wear and extend the service life of the components.

[0049] Since the connection between the quick-lock rotating shaft 1 and the quick-lock seat 4 is achieved through steps, it can be quickly disassembled and reassembled when maintenance or component replacement is required, which helps to reduce maintenance costs and downtime.

[0050] This design of the quick-lock rotating shaft 1 can adapt to different installation environments and requirements. Whether under light load or heavy load conditions, it can provide reliable locking performance. The O-ring 2 sealing and the step design work together to improve the durability of the quick-lock assembly, enabling it to be used for a long time under various environmental conditions and maintaining its performance without attenuation.

[0051] Semicircular holes are opened on the cross axis of the circular hole opened in the center of the quick-lock seat 4. The semicircular holes can provide additional positioning surfaces, which helps to improve the alignment accuracy with the quick-lock pressure plate 9 and ensure the stability of the connection.

[0052] The steel ball 8 is installed at one end far from the quick-lock rotating shaft 1 and matches the semicircular hole of the quick-lock seat 4.

[0053] The precise fit of the steel ball 8 with the semi-circular hole can ensure the precise alignment of the quick-lock assembly during connection, which is particularly important for applications that require frequent disassembly and assembly, such as in automated production lines or during tool replacement processes. It can significantly improve work efficiency and assembly accuracy. The semi-circular hole provides a stable mating surface for the steel ball 8, helping to improve the alignment accuracy with the quick-lock pressure plate 9 and ensuring the stability of the connection. This design helps to prevent unlocking caused by accidental collisions or vibrations, enhancing the safety during use. The cam-shaped cross-section or semi-circular hole design can provide a self-locking mechanism after the spring is compressed, enabling the spring to maintain its compressed state at a certain rotation angle, which helps to maintain the locked state of the quick-lock assembly and prevent accidental unlocking. The fit between the steel ball 8 and the semi-circular hole can reduce the direct contact between metals, thereby reducing wear and extending the service life of the components. Especially in applications that require frequent installation and disassembly, this design reduces wear and damage during the assembly process.

[0054] In summary, the matching design of the steel ball 8 with the semi-circular hole of the quick-lock base 4 provides an efficient, reliable, and easy-to-operate locking solution.

[0055] The following describes a specific usage scenario: The device to be locked is internally designed with a special lock head, and the inner hole design of the lock head is precisely matched with the L-shaped inner hole of this device to ensure perfect docking between the two. To further enhance the connection stability, the lock head is also specially designed with screw holes, and the device can be firmly fixed by tightening the screws.

[0056] The installation process is extremely simple. The user only needs to gently place this device aligned with the inner hole of the lock head to achieve preliminary positioning. Subsequently, through simple operations, the locking can be completed. Specifically, this device is equipped with a cleverly designed cam-shaped quick-lock wrench 6. The user only needs to press down on this wrench, and the cam part of the wrench will apply pressure to the quick-lock pressure plate 9 below, causing it to tightly press against the surface of the lock head.

[0057] The material selection of the quick-lock pressure plate 9 is very flexible and can be various types of gaskets, such as flat gaskets or tapered gaskets, etc., to adapt to different locking requirements and surface characteristics. When the quick-lock pressure plate 9 is subjected to a pressing force, this force is transmitted to the quick-lock rubber spring 3 through the quick-lock base 4 below it. The design of the quick-lock rubber spring 3 is also crucial. Its cam-shaped cross-section will generate an outward reaction force when compressed, enabling this device to closely fit against the outer surface of the lock head.

[0058] This ingenious mechanical design enables the device to achieve self-locking rapidly after installation, without the need for additional fixing components or complex operation steps. The effect of rapid self-locking not only improves work efficiency but also ensures the safety and reliability of the connection. Especially in occasions where quick installation and disassembly are required, such as in the fields of production lines, mechanical equipment, medical devices, etc., the advantages of this device are particularly obvious. Through this design, the device provides users with a fast, simple, and efficient locking solution.
