Description
Technical Field
[0001] This utility model belongs to the field of locking technology, specifically relating to a quick-release plate locking mechanism that allows for rapid engagement. Background Technology
[0002] Existing panels requiring locking and fastening are typically connected using bolts, clips, or welding. While traditional bolt fastening provides reliable locking force, it suffers from low installation efficiency and requires specialized tools, making it particularly unsuitable for logistics scenarios involving frequent disassembly and assembly. Common clip structures, while simplifying installation, lack sufficient locking stability, making quick-release plates prone to loosening or even detachment under vibration or external impact, affecting the overall structural reliability of the panel. Some improved clips employ a modular design, relying on a single locking point for fixation, resulting in concentrated locking force in a localized area. Long-term use can lead to structural deformation. The lack of a multi-stage locking mechanism makes them unable to effectively resist vibration and impact during handling, requiring strict alignment of the locking components, resulting in low operational error tolerance and increased assembly difficulty.
[0003] Chinese Patent CN110342061B discloses a quick-release plate locking mechanism, including a locking pin and a blocking block. The head of the locking pin has a rotating protrusion. The lower part of the locking pin, which is connected to the blocking block, has a cuboid structure. The tail of the locking pin is hinged to the blocking block. A V-shaped spring is sleeved on the hinge. The two ends of the V-shaped spring are respectively in contact with the surfaces of the locking pin and the blocking block. There is a cylindrical protrusion in the middle of the locking pin. Springs are pressed onto the upper and lower ends of the protrusion, and the springs are respectively sleeved on the locking pin. The locking pin extends out and fits against the side wall of the quick-release plate box lid. A first through hole is opened on the side wall of the quick-release plate box lid, and a second through hole is opened on the side wall of the quick-release plate box. A first groove is opened at the spring on the corresponding locking pin in the first through hole, and a second groove is opened at the tail of the corresponding locking pin. The second groove is a column with unequal distances between its two pairs of sides. The aforementioned device requires sequential actions such as rotation, spring compression, and groove alignment during locking, making the operation cumbersome and difficult to achieve rapid locking. Therefore, it is imperative for those skilled in the art to solve the aforementioned technical problems. Summary of the Invention
[0004] The present invention aims to solve the problem that the existing locking process is cumbersome and difficult to achieve fast locking.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A quick-release plate latch is provided for quickly locking adjacent quick-release plates together and for quick opening, enabling rapid locking and separation of interlocking quick-release plates; characterized in that the latch comprises:
[0007] At least one latch mounting slot, said latch mounting slot being fixed to one of the quick-release plates; and
[0008] At least one set of locking assemblies, wherein the locking assemblies are respectively installed on the locking mounting slots, and the locking assemblies include a fastening lock and a rotation positioning lock;
[0009] When the quick-release plate is assembled, the fastening latch and the rotary positioning latch engage together to lock the quick-release plate.
[0010] By adopting the above technical solution, the locking process between quick-release plates is made extremely rapid through the design of the snap-fit and rotary positioning locks. This significantly shortens assembly time, improves work efficiency, and eliminates the need for additional tools or complex steps, reducing the skill requirements for operators. The use of corrosion-resistant materials such as stainless steel in the lock components enhances their corrosion resistance and improves the overall structural strength and stability. The snap-fit design of the limiting boss and connecting hole, along with the application of locking bolts, ensures that the locking state remains stable even under vibration or impact during transportation, guaranteeing cargo safety. The number and position of the snap-fit locks can be adjusted according to actual needs to accommodate cargo loading requirements of different sizes and weights. The design of the lock components facilitates quick installation and removal, providing convenience for frequently used scenarios.
[0011] Furthermore, the latching buckle includes a positioning part and a connecting part, wherein the positioning part has a groove structure that engages with the latch mounting groove;
[0012] The rotary positioning latch includes a rotatable rotary pin and a connecting part, wherein the rotary pin of the rotary positioning latch is mounted on the positioning part of the rotary positioning latch;
[0013] The rotary positioning latch is located in the latch mounting groove on the top of the quick-release plate, and the latches are distributed at intervals along the height direction of the quick-release plate.
[0014] By adopting the above technical solution, the groove structure of the latching buckle and the snap-fit design of the buckle mounting slot provide a precise positioning function, ensuring that the buckle assembly can be installed accurately. The design of the positioning part helps to avoid unnecessary movement or displacement of the buckle assembly during use, thereby ensuring a tight connection between the quick-release plates. The rotating pin in the rotating positioning buckle can be adjusted according to actual needs, providing convenience for splicing quick-release plates at different angles and positions, increasing the flexibility in the assembly process. Due to the presence of the rotating pin and the positioning part, the latching process between the quick-release plates is simpler, and quick locking can be achieved without complicated alignment work. The latching buckles distributed at intervals along the height direction of the quick-release plates and the rotating positioning buckle located on the top of the quick-release plates combine to form a multi-layered safety protection system, effectively enhancing the stability and impact resistance of the entire structure.
[0015] Furthermore, the positioning part of the latch includes an integrally formed mounting groove, a positioning pin, and a positioning plate with a connecting hole; the connecting part includes a pad that fits against the inner wall of the mounting groove and a locking bolt that passes through both.
[0016] The positioning pin is disposed on the outer wall of the mounting groove, and the positioning pin is adapted to the connecting hole;
[0017] The positioning part is installed in the locking mounting groove by the locking bolt.
[0018] By adopting the above technical solutions, the matching design of the locating pin and the connecting hole ensures precise alignment between the locating part and the quick-release plate, thereby improving the installation accuracy of the entire locking assembly. The design of the locking bolt penetrating the pad and the mounting groove provides a robust mechanical connection, enhancing the stability and durability of the overall structure. The one-piece molded mounting groove and locating plate design reduces the number of parts, making the installation process simpler and faster. At the same time, the design of the locking bolt also facilitates quick disassembly and maintenance. The matching design of the locating pin and the connecting hole allows for fine-tuning within a certain range to adapt to different installation requirements and environmental conditions. The one-piece locating part and pad, made of high-quality materials, can effectively resist wear during daily use, extending the service life of the locking assembly. The use of the locking bolt not only increases structural strength but also provides an additional protective layer, preventing external factors such as moisture and dust from affecting the internal mechanism.
[0019] Furthermore, the positioning part of the rotary positioning lock includes a mounting groove, a positioning plate with a connecting hole, and a rotatable rotary pin. The rotary pin is provided with a connecting shaft with a limiting boss. When the rotary pin is in the locked position, the limiting boss is engaged with the connecting hole of the mounting groove.
[0020] By adopting the above technical solution, when the rotating pin is in the locked position, the limiting boss engages with the connecting hole of the mounting groove, forming a physical barrier and adding an extra layer of security. This design ensures that the latch is not easily opened accidentally even under external force. The limiting boss design effectively prevents unintended unlocking due to misoperation or vibration, improving the safety and reliability of the entire system. The rotating pin design allows users to flexibly adjust the locking state as needed, easily achieving locking and unlocking operations without complete disassembly, greatly improving ease of use. This design can adapt to locking requirements at different angles and directions, and is suitable for more complex or variable working environments. By limiting the range of motion of the rotating pin and using the limiting boss for precise alignment, unnecessary friction and wear can be reduced, extending the service life of the latch assembly.
[0021] Furthermore, the limiting boss of the rotating pin and the connecting shaft are integrally formed, and the mounting groove of the rotating positioning lock is also equipped with a positioning hole, and the connecting shaft is rotatably installed in the positioning hole.
[0022] By adopting the above technical solution, the limiting boss and connecting shaft are designed as a single piece, which significantly enhances the connection strength between these two key components and reduces the risk of loosening or breakage due to long-term use. Compared with separate assemblies, single-piece components generally have higher mechanical strength and durability. By reducing the number of joints between parts, potential failure points are lowered, making the entire rotating pin structure more reliable and suitable for long-term stable operation under high loads or harsh environments. The rotating pin is rotatably mounted in the positioning hole on the mounting groove via its connecting shaft, ensuring the accuracy and repeatability of each rotation. This not only helps maintain the consistency of the locked state but also makes the unlocking process smoother, improving the accuracy and efficiency of operation. The presence of the positioning hole allows for easier installation and adjustment of the rotating pin, achieving precise positioning without complex alignment steps, thereby speeding up assembly and reducing the error rate.
[0023] Furthermore, the quick-release plate is provided with three locking latches and one rotary positioning latch on its side, and the rotary positioning latch and the locking latch are made of stainless steel.
[0024] By adopting the above technical solutions, stainless steel, renowned for its excellent mechanical properties, provides higher strength than ordinary steel. Even under significant pressure or impact, the latch is not easily deformed or damaged. Stainless steel also possesses excellent corrosion resistance, especially in humid or chemically-containing environments, effectively preventing rust and corrosion, thus extending the latch's service life. Multiple interlocking latches ensure the quick-release plate is securely fixed in all directions, improving the overall structural safety. The rotary positioning latch provides an additional locking mechanism when needed, further enhancing protection. The use of stainless steel ensures the latch will not loosen or fail in other ways during prolonged use, guaranteeing the stability of the quick-release plate connection.
[0025] Furthermore, both the snap-fit latch and the rotary positioning latch are provided with four locking bolts and two pads.
[0026] By adopting the above technical solution and using four locking bolts, the contact area and number of fixing points between the latch and the quick-release plate can be greatly increased, thereby providing stronger gripping force and shear resistance, making the entire structure more robust, reducing the risk of loosening due to external forces, and multiple locking bolts help to distribute the pressure applied to the latch more evenly, avoiding deformation or damage caused by excessive force on a single point. The presence of the pad can form a buffer between the latch and the quick-release plate, reducing friction and wear between direct metals, protecting the surface of the quick-release plate from damage, and extending the service life of the latch itself. Different materials have different coefficients of thermal expansion, and setting up the pad can leave room for dimensional changes caused by temperature changes, preventing structural damage caused by thermal expansion and contraction.
[0027] This utility model has the following beneficial effects:
[0028] 1. This utility model achieves a rapid locking process between quick-release plates by using a snap-fit lock and a rotary positioning lock. The locking action can be completed without the use of additional tools or complex steps. This not only greatly shortens the assembly time and improves work efficiency, but also reduces the skill requirements of the operators. The ingenious design of the lock assembly ensures that it can maintain a stable locking state even when subjected to vibration or impact during transportation, thus ensuring the safety of the goods.
[0029] 2. This utility model uses corrosion-resistant materials such as stainless steel to make the locking assembly, and combines the design of four locking bolts and two pads, which significantly enhances the strength and stability of the overall structure. It can effectively resist the influence of adverse external factors, adapt to the dimensional changes caused by temperature changes, and prevent structural damage caused by thermal expansion and contraction. At the same time, the one-piece molded mounting groove and positioning plate reduce the number of parts, simplify the installation process, and extend the service life of the locking assembly.
[0030] 3. This utility model provides an additional layer of safety protection through the snap-fit design of the limiting boss and the connecting hole and the application of the locking bolt, ensuring that the lock is not easy to open accidentally, increasing the safety and reliability of the entire system. The design of the rotating pin allows users to flexibly adjust the locking state according to actual needs, and can easily achieve locking and unlocking operations without complete disassembly, improving the convenience of use. According to the different sizes and weight requirements of the goods, the number and position of the buckles can be adjusted to adapt to more complex or changeable working environments, providing a multi-layered safety protection system.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.
[0041] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.
[0042] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As can be seen, this utility model discloses a quick-release plate latch, which consists of a quick-release plate 10, latch mounting grooves 11, and latch assembly 20. Four latch mounting grooves 11 are vertically formed on the side of the quick-release plate 10. The latch assembly 20 is installed in each latch mounting groove 11. The latch assembly 20 includes two types: snap-fit latches 21 and rotary positioning latches 22. The snap-fit latches 21 are spaced apart along the height of the quick-release plate, and the rotary positioning latches 22 are fixed to the top latch. In the mounting groove 11, both the snap-fit latch 21 and the rotary positioning latch 22 include a positioning part 201 and a connecting part 202. The positioning part 201 of the snap-fit latch 21 includes an integrally formed mounting groove 211, a positioning pin 212, and a positioning plate 213 with a connecting hole 2131. The mounting groove 211 is installed in the latch mounting groove 11. The positioning pin 212 is vertically disposed on the outer wall of the mounting groove 211 and is inserted into the connecting hole 2131 on the positioning plate 213 of the adjacent quick-release plate 10.
[0043] The connecting part 202 of the latching buckle 21 includes two pads 223 and four locking bolts 222. The pads 223 fit against the inner wall of the mounting groove 211, and the locking bolts 222 pass through the side wall of the groove and the pads 223. The latching buckle 21 is fixed to the buckle mounting groove 11 by the thread preload.
[0044] The difference between the positioning part 201 of the rotary positioning latch 22 and the positioning part 201 of the latching latch 21 is that the positioning pin 212 is replaced by a rotary pin 221. The rotary pin 221 includes an integrally formed limiting boss 2211 and a connecting shaft 2212. The connecting shaft 2212 is rotatably installed in the positioning hole 2111 of the positioning part 201. When the limiting boss 2211 is rotated to the locking position, it is engaged with the connecting hole 2131 of the mounting groove 211 to form a mechanical self-locking. The latching latch 21 and the rotary positioning latch 22 are made of stainless steel. The quick release plate on one side is equipped with three latching latches 21 and one rotary positioning latch 22 to form a distributed locking system with top rotary locking and three middle latching.
[0045] Each locking assembly 20 achieves rapid alignment through the guide insertion of the positioning pin 212 and the connecting hole 2131. The 90° rotation locking action of the rotating pin 221 completes the final locking. The entire process requires no tool assistance and quickly achieves the locking and positioning of the quick-release plate 10.
[0046] Working principle: First, the positioning pin 212 of the latching latch 21 engages with the connecting hole 2131 on the positioning plate 213 of the adjacent quick-release plate 10 through an insertion fit, achieving rapid alignment during quick-release plate assembly. The snap-fit structure between the mounting groove 211 and the latch mounting groove 11 further constrains the relative position of the quick-release plates, completing the initial positioning. Next, the top rotating positioning latch 22, through the 90° rotation of the rotating pin 221, causes its limiting boss 2211 to engage with the connecting hole 2131 of the adjacent quick-release plate mounting groove 211, forming an interference fit mechanical self-locking to resist the pull force of the quick-release plate disengaging. Finally, the three latching latches 21 are distributed at intervals along the height of the quick-release plates. The insertion of the positioning pin 212 with the connecting hole 2131 constrains lateral displacement, and the top rotating positioning latch 22 suppresses longitudinal displacement, forming a multi-point coordinated three-dimensional locking system. The locking bolt 222 can be simply tightened to complete the final fixation without the need for special tools. The locking mechanism of the latch 21 is separated from the rotational self-locking action of the rotating positioning latch 22. First, the positioning pin 212 is used for quick alignment, and then the rotating pin 221 is used to complete the final locking with one hand. The two-stage action is seamlessly connected to achieve a quick locking process of "one-insert-one-rotate".
[0047] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
