Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation, and in particular to a collision automatic locking and automatic tripping structure. Background Art

[0002] In fields such as mechanical engineering, equipment connection, and industrial automation, reliable connection and convenient separation between various devices are important technical requirements, especially in scenarios where collisions may occur, such as the connection of components in transportation equipment and the modular combination of construction machinery. The connection structure not only needs to be automatically locked in the event of a collision to ensure system stability, but also needs to be able to quickly and safely release when needed to meet the separation requirements for equipment maintenance, reorganization, or emergency situations.

[0003] Traditional mechanical locking structures usually rely on manual operation to achieve connection and separation, such as bolt and nut connections, snap-on connections, etc. These structures are difficult to achieve automatic response locking action when facing sudden collisions, and often require manual intervention for adjustment or locking, which is inefficient and unreliable. At the same time, some structures with automatic locking functions require complex operating steps or additional unlocking devices when tripping, which makes them inconvenient to use and may even affect the normal use or safety performance of the equipment due to cumbersome operations.

[0004] In addition, the connection structures in the existing technology for collision scenarios often lack effective utilization of collision forces in design. For example, the kinetic energy during the collision cannot be converted into locking power, resulting in structural redundancy or poor locking effect. Moreover, the reset mechanism and limit design of the traditional structure have limitations, and problems such as inability to maintain stability after locking or jamming during release may occur, making it difficult to meet the high-precision and high-reliability industrial application requirements. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides an automatic locking and automatic release structure in the event of a collision. The automatic locking and automatic release structure in the event of a collision provided by the present invention realizes automatic dislocation locking and resetting in the event of a collision through the oblique design of the hook and the cooperation of the positioning column and the compression spring. At the same time, convenient release is achieved by the rotation of the positioning sleeve, which effectively solves the problems of cumbersome operation, untimely response and poor reliability in the existing technology, and has broad application prospects and technical advantages.

[0007] (2) Technical solution

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a collision automatic locking and automatic tripping structure, which has the following beneficial effects:

[0018] The collision automatic locking and automatic release structure is that when the hooks between two adjacent devices touch each other, the two hooks will rotate relative to each other with the help of the oblique design of the hooks and the rotation of the positioning column, so that the two hooks can be relatively staggered. After they are completely staggered, the rebound of the compression spring can drive the limit plate to rotate the positioning column in the opposite direction, so that the hooks are reset and the relative locking is completed. When unlocking, it is only necessary to rotate the positioning sleeve to drive the hook to rotate upward, so that the two hooks are opened and the release of the device is completed.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 6 The present invention provides a technical solution: a collision automatic locking and automatic release structure. It includes a fixing seat 1, wherein:

[0028] Both sides of the outer wall of the fixed seat 1 are fixedly connected with positioning plates 2, and a positioning sleeve 3 is rotatably connected between the positioning plates 2. The inner wall of the positioning sleeve 3 is rotatably connected with a positioning column 11, one side of the positioning column 11 is fixedly connected with a limiting plate 12, and the outer wall of the limiting plate 12 is fixedly connected with a compression spring 13, and the other side of the positioning column 11 is fixedly connected with a hook 14.

[0029] The locating plate 2 is located on both sides of the outer wall of the fixing seat 1, and the locating plate 2 is fixedly connected to the fixing plate 2 on both sides of the fixing seat 1 during operation, so as to ensure that the entire structure has a stable foundation during collision, locking and tripping, and prevent the entire structure from shaking or displacement, and ensure that other components can function normally. The locating plate 2 is located on both sides of the outer wall of the fixing seat 1 and is symmetrically distributed on the left and right. Its main function is to provide a fulcrum for the locating sleeve 3 to rotate. Through the rotatable connection with the locating sleeve 3, the locating sleeve 3 is limited to rotate within a certain range, thereby laying the foundation for the subsequent rotation, locking and tripping of the hook 14, and ensuring that the movement of the structure has precise directionality and stability. The locating sleeve 3 is installed between the two locating plates 2 and can rotate in the space defined by the locating plates 2. Its inner wall is opened It is provided with an installation groove 4, and the side wall of the installation groove 4 is provided with an installation hole for installing components such as the positioning shaft 5. The positioning sleeve 3 plays a key role in connecting the upper and lower parts in the structure. On the one hand, it cooperates with the positioning plate 2 to realize rotation. On the other hand, it provides installation space and movement track for components such as the positioning column 11. During the tripping process, the positioning sleeve 3 is driven to drive the hook 14 to rotate upward to realize the tripping and separation of the structure. The positioning column 11 is installed on the inner wall of the positioning sleeve 3 and can rotate in the positioning sleeve 3. One side of it is connected to the limit plate 12 and the other side is connected to the hook 14. During a collision, the positioning column 11 will rotate with the collision force applied to the hook 14, realizing the relative rotation and staggered action of the hook 14. It is the core rotating component for realizing the automatic locking function of collision. The flexibility and stability of its rotation directly affect the locking effect. The limit plate 12 is fixed on one side of the positioning column 11, and the outer wall is connected to the compression spring 13. When the positioning column 11 rotates under the action of the collision force, the limit plate 12 rotates the compression spring 13 accordingly. After the two hooks 14 are completely staggered, the compression spring 13 rebounds and drives the limit plate 12 to rotate the positioning column 11 in the opposite direction, so that the hook 14 is reset to complete the locking action, which plays the role of transmitting the spring force and controlling the rotation direction of the positioning column 11. One end of the compression spring 13 is connected to the limit plate 12, and the other end is fixed to the inner wall of the mounting groove 4 of the positioning sleeve 3. During the collision process, the spring is compressed to store elastic potential energy. When the hook 14 is staggered, the spring releases the elastic potential energy, pushing the limit plate 12 It drives the positioning column 11 to rotate in the opposite direction, providing power for the reset and locking of the hook 14, and is a key power component for realizing automatic locking. The hook 14 is fixed on the other side of the positioning column 11 and is a component directly involved in connection and locking. The outer surface of the hook 14 is fixedly connected with a paddle 15, which is convenient for manual operation or to paddle the hook 14 under specific circumstances. The hook 14 adopts an oblique design. When two adjacent devices collide, the two hooks 14 are staggered in relative rotation by virtue of their own oblique structure and the rotation of the positioning column 11, and then locked by spring reset, realizing automatic connection between the devices.

[0030] The inner wall of the positioning sleeve 3 is provided with a mounting groove 4, and both sides of the inner wall of the mounting groove 4 are provided with mounting holes through.

[0031] The inner wall of the mounting hole is rotatably plugged with a positioning shaft 5, and the end of the positioning shaft 5 is fixedly connected to a limiting plate. The positioning shaft 5 is rotatably plugged into the inner wall of the mounting hole of the positioning sleeve 3, and its end is fixedly connected to the limiting plate to prevent the positioning shaft 5 from falling out. A limiting groove 6 is provided on the outer surface of the shaft, which is engaged with the limiting block 7 on the inner wall of the mounting hole to limit the rotation range of the positioning shaft 5, ensuring that the positioning shaft 5 rotates within a specific angle, thereby ensuring the accuracy and stability of the movement of the associated components. One end of the positioning shaft 5 passing through the positioning sleeve 3 is threadedly connected to the connecting rod 8, and the retaining ring at the end of the connecting rod 8 can prevent the connecting rod 8 from falling off, and at the same time play a certain limiting and protective role in the operation of the structure.

[0032] The outer surface of the positioning shaft 5 is provided with a limiting groove 6, the inner side wall of the mounting hole is fixedly connected to the limiting block 7, and the outer surface of the limiting block 7 is engaged with the inner wall of the limiting groove 6 and passes through.

[0033] One end of the positioning shaft 5 passing through the positioning sleeve 3 is threadedly connected to a connecting rod 8, and the end of the connecting rod 8 is fixedly connected to a retaining ring. By rotating the connecting rod 8, the positioning sleeve 3 can be directly driven to rotate, and the connecting rod 8 can be directly driven to rotate with the help of an external control device, thereby facilitating the realization of automatic tripping.

[0034] The top of the positioning sleeve 3 is plugged with a positioning bolt 9, and one end of the positioning bolt 9 passing through the positioning sleeve 3 is threadedly connected with a positioning nut 10. The positioning bolt 9 passes through the outer wall of the positioning sleeve 3 and is rotatably plugged into the top of the positioning post 11. The positioning bolt 9 and the positioning nut 10 are threadedly connected to fix the positioning post 11 and the positioning sleeve 3 relatively, while allowing the positioning post 11 to rotate within a certain range, playing a dual role of connection and limit. By adjusting the tightening degree of the positioning nut 10, the tightness between the positioning post 11 and the positioning sleeve 3 can be accurately controlled to ensure the stability of the position of the positioning post 11 in the structure, ensuring that the positioning post 11 can maintain a stable installation position during the operation of the structure, and can be flexibly rotated to achieve collision automatic locking and tripping functions. At the same time, it is convenient to install, disassemble and debug the positioning post 11, thereby improving the maintainability and versatility of the structure.

[0035] A paddle 15 is fixedly connected to the outer surface of the hook 14, and the other end of the compression spring 13 is fixedly connected to the inner wall of the mounting groove 4. The design of the paddle 15 on the outer surface of the hook 14 allows the hook 14 to be manually toggled and forced to be released when necessary, such as manually releasing the component in an emergency, thereby improving operational flexibility.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller, and the main controller can be a conventional known device for controlling a computer or the like.

[0037] In summary, when the collision automatic locking and automatic tripping structure is used:

[0038] 1. During the collision process, when two adjacent devices collide, the inclined surfaces of the hooks 14 come into contact with each other. Under the action of the collision force, the positioning column 11 begins to rotate, compressing the spring 13, causing the hooks 14 to stagger. As the positioning column 11 rotates, the two hooks 14 will stagger relative to each other until they completely pass each other. The spring resets. After the hooks 14 stagger, the compressed spring 13 releases its elastic potential energy, driving the positioning column 11 to rotate in the opposite direction, restoring the hooks 14 to their initial position, thereby achieving automatic locking.

[0039] 2. By directly rotating the connecting rod 8 with the help of an external control device, the positioning sleeve 3 can be driven to rotate, thereby achieving the tripping operation.
