Technical Field

[0001] This utility model relates to the technical field of self-locking structures, and in particular to a fast self-locking structure. Background Technology

[0002] A self-locking mechanism is a special type of mechanical structure whose core feature is its ability to automatically maintain a locked state, preventing accidental unlocking under external forces and thus ensuring structural stability and safety. Self-locking mechanisms are widely used in various mechanical devices, door and window locking systems, furniture connectors, and other fields to improve operational convenience and reliability. However, the design and manufacture of self-locking mechanisms currently typically require higher precision and more complex processes, resulting in relatively high costs. Furthermore, the design of self-locking mechanisms is relatively complex, resulting in a redundant structure and difficulties in maintenance.

[0009] Furthermore, the axial length of the driving roller is greater than the axial length of the auxiliary roller.

[0010] Furthermore, the radius of curvature of the limiting slot is slightly larger than the radius of the active roller and the auxiliary roller.

[0011] Furthermore, both the drive roller and the auxiliary roller can rotate around the connecting shaft.

[0012] Furthermore, the guide surfaces of the first and second guide stages are arc-shaped.

Detailed Implementation

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0021] Please see Figure 1-3It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0022] Please see Figures 1 to 3 This utility model provides a quick self-locking structure 100, including a base 1 and a self-locking mechanism. The base is adjustablely mounted on a mounting body, which can be a door panel, mechanical device, or other entity that requires a locking structure.

[0023] The self-locking mechanism includes a self-locking part 2 located in the middle of the base 1 and a lock cylinder assembly 3 rotatably mounted on the self-locking part 2. Specifically, the self-locking part 2 includes a lock cylinder through hole 21 perpendicular to the base 1, a limiting groove 22 extending outward from the lock cylinder through hole 21 along the length direction of the base 1, and a stepped first guide platform 23 and a second guide platform 24; the height of the first guide platform 23 is higher than the height of the second guide platform 24, and both are smoothly connected to the limiting groove 22; the lock cylinder assembly 3 includes a lock cylinder 31 that passes through the lock cylinder through hole 21 sequentially through the self-locking part 2 and the base 1, and a latch 32 located at the upper end of the lock cylinder 31 and rotating synchronously with the lock cylinder 31.

[0024] The locking slot 22 limits the locking of the latch 32, ensuring that the lock cylinder assembly 3 can be firmly locked in the locked state and preventing accidental unlocking. The layout of the lock cylinder 31 and the latch 32 can better distribute the pressure during locking, reduce local stress concentration, thereby extending the service life of the lock cylinder assembly 3 and reducing wear caused by long-term use. The design of each component of this utility model is relatively compact, and it can achieve efficient locking function in a limited space.

[0025] Furthermore, high-precision manufacturing processes such as CNC machining or precision casting can be used to ensure that the dimensions of the limit slot 22, the first guide table 23, the second guide table 24, and the latch 32 meet the requirements for mutual matching.

[0026] Preferably, a position sensor such as a photoelectric sensor or a magnetic sensor can be installed at the contact point between the limit slot 22 and the latch 32 to monitor the position and status of the latch in real time and issue an alarm in case of self-locking failure.

[0027] Please continue reading. Figure 1 and Figure 2 The latch 32 includes an active roller 321, an auxiliary roller 322, and a connecting shaft 323. The active roller 321 and the auxiliary roller 322 are respectively located on both sides of the upper end of the lock cylinder 31, and are connected by the connecting shaft 323. The connecting shaft 323 passes through the upper end of the lock cylinder 31. Both the active roller 321 and the auxiliary roller rotate around the connecting shaft 323.

[0028] Preferably, a retaining ring or nut is provided at the end of the auxiliary wheel 322 away from the active roller 321 to ensure that the auxiliary wheel 322 and the active roller 321 are axially fixed during the movement of the latch 32 and will not be displaced along the axial direction. Even if the angle of rotation of the lock 32 is too large, it can be ensured that the auxiliary roller 322 can accurately retract to the second guide platform when the lock cylinder 32 rolls back.

[0029] In addition, oil or grease lubrication can be added at the contact points between the connecting shaft 323 and the drive roller 321 and the auxiliary roller 322 to reduce friction and wear and lower noise levels. At the same time, damping materials, such as rubber or silicone pads, can be installed between the connecting shaft 323 and the drive roller 321 and the auxiliary roller 322 to reduce vibration and noise and further improve the stability of the structure's operation.

[0030] Please continue reading. Figure 1 and Figure 2 The first guide platform 23 is positioned on one side near the active roller 321 to guide the active roller 321; the second guide platform 24 is positioned on one side near the auxiliary roller 322 to guide the auxiliary roller 322.

[0031] Please continue reading. Figure 1 and Figure 2 The axial length of the active roller 321 is greater than the axial length of the auxiliary roller 322.

[0032] In a preferred embodiment, the active roller 321 and the auxiliary roller 322 have the same diameter, ensuring that the active roller 321 and the auxiliary roller 322 roll smoothly on the first guide platform 23 and the second guide platform 24, respectively.

[0033] In the locked state, since the axial length of the active roller 321 is greater than that of the auxiliary roller 322, the active roller 321 can provide a larger contact area and a stronger locking force, effectively preventing the lock cylinder 31 from being accidentally unlocked under the action of external force and improving the reliability of locking.

[0034] Preferably, the surfaces of the active roller 321 and the auxiliary roller 322 can be treated by hard chrome plating or polytetrafluoroethylene coating to improve their wear resistance and lubricity and reduce friction and wear.

[0035] Please see Figure 1 and Figure 2 The radius of curvature of the limiting slot 22 is slightly larger than the radius of the active roller 321 and the auxiliary roller 322.

[0036] Specifically, a smooth transition area can be designed at the entrance and exit of the limiting slot 22 to reduce the impact force when the active roller 321 and the auxiliary roller 322 enter and exit the limiting slot; at the same time, the transition area can adopt a gradual arc design so that the active roller 321 and the auxiliary roller 322 can enter and exit the limiting slot 22 more smoothly.

[0037] Please see Figure 1 The guide surfaces of the first guide platform 23 and the second guide platform 24 are arc-shaped.

[0038] Specifically, when the active roller 321 and the auxiliary roller 322 reach the limit slot 22, due to the arc design of the first guide plate 23, the latch can smoothly roll into the limit slot 22 and complete the locking.

[0039] The implementation principle of the quick self-locking structure 100 in this utility model is as follows: When locking, the lock cylinder 31 is rotated, so that the active roller 321 and the auxiliary roller 322 roll along the first guide plate 23 and the second guide plate 24 respectively into the limiting slot 22, and the lock cylinder 31 descends to the predetermined position to complete the self-locking; when unlocking, the lock cylinder assembly 3 is slowly raised, and the active roller 321 and the auxiliary roller 322 on the latch 32 roll from the limiting slot 22 in the opposite direction to the first guide plate 23 and the second guide plate 24 until the lock cylinder 31 leaves the locked position to complete the unlocking.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
