The housing 1 is used to assemble the actuator and the magnetic induction unlocking assembly. The actuator includes a drive rod 2, a return spring 3, and a locking assembly. The drive rod 2 is movably disposed within the housing 1, with its upper end extending out of the housing. The return spring 3 is used to push the drive rod 2 upward. The locking assembly is used to lock or unlock the drive rod 2. The up-and-down movement of the drive rod 2 can drive the locking assembly to move. The magnetic induction unlocking assembly 5 includes an electromagnet 5.1 and a sliding insert 5.2. A magnet 5.3 is fixed to the sliding insert 5.2.

[0021] Specifically, based on the above, the housing is provided with an installation cavity, the side wall of the installation cavity 1.11 is provided with a plurality of positioning plates 1.12, a sliding groove 1.13 is formed between two adjacent positioning plates 1.12, the bottom of the positioning plate 1.12 is provided with a positioning groove 1.14, the installation cavity 1.11 is also provided with a positioning post 1.15, the locking assembly includes a limiting ring 4, the limiting ring 4 is rotatably sleeved on the bottom of the drive rod 2, and the outer side of the limiting ring 4 is provided with a limiting member 4.1 corresponding to the positioning groove 1.14, the outer side of the drive rod 2 is provided with a threaded sliding groove 2.3 that cooperates with the positioning post 1.15, the housing is also provided with an annular drive tooth 1.23, the drive tooth 1.23 is located below the positioning plate 1.12, and the return spring 3 is provided in the housing and abuts against the drive rod 2. The housing includes a detachable upper housing 1.1 and a lower housing 1.2. A mounting cavity 1.11 is located inside the upper housing 1.1, and a drive gear 1.23 is located in the lower housing 1.2. The lower housing 1.2 is provided with a fixing post 1.21, and a fixing hole 2.23 is provided in the middle of the drive rod 2. A return spring 3 is sleeved on the outside of the fixing post 1.21 and is embedded in the fixing hole 2.23 and abuts against the drive rod 2. The detachable upper housing 1.1 and lower housing 1.2 can effectively improve the assembly efficiency of the actuator. At the same time, sleeved on the outside of the fixing post 1.21, the return spring 3 can be guaranteed to be reliable and prevent the return spring 3 from shaking or shifting.

[0022] To further explain, the lower housing 1.2 is provided with a fixed sleeve 1.22, and the drive tooth 1.23 is located inside the fixed sleeve 1.22. When the lower end of the drive rod 2 moves downward, it can penetrate into the fixed sleeve 1.22. The upper housing 1.1 is provided with a movable opening 1.16 and a guide groove 1.17. The positioning pin 5.22 is laterally slidably located in the guide groove 1.17 and can penetrate through the movable opening 1.16 and extend into the locking hole 2.1. The fixed sleeve 1.22 facilitates the processing and forming of the drive tooth 1.23 and improves the stability of the drive tooth 1.23.

[0023] It is worth mentioning that an assembly cavity 1.3 for assembling the sliding plug 5.2 is also provided between the upper housing 1.1 and the lower housing 1.2. The sliding plug 5.2 is movably disposed in the assembly cavity 1.3. The electromagnet 5.1 is fixed to the lower housing 1.2. The sliding plug 5.2 is provided with a movable cavity 5.24. The sliding plug 5.2 covers the outside of the electromagnet 5.1, and magnets 5.3 are provided at both ends of the movable plug. Specifically, the sliding plug 5.2 is provided with a limiting block 5.21, and the upper housing 1.1 is provided with limiting plates 1.18 located on both sides of the limiting block 5.21. The limiting block 5.21 has a guide groove 5.23 along its sliding direction, and the upper housing 1.1 is also provided with a slide rail 1.19 that cooperates with the guide groove 5.23. The advantage is that the cooperation between the limiting plate 1.18 and the limiting block 5.21 can limit the movement stroke of the sliding plug 5.2 and avoid excessive movement. At the same time, the cooperation between the guide groove 5.23 and the slide rail 1.19 can ensure the movement stability of the sliding plug 5.2.

[0024] It should be noted that the two magnets 5.3 are arranged such that their adjacent end faces repel each other. This ensures that when the electromagnet 5.1 is placed between the two magnets 5.3, and when the electromagnet 5.1 is energized, it can simultaneously act on both magnets 5.3, thereby enhancing the force on the sliding plug 5.2 and ensuring the reliable movement of the sliding plug 5.2.

[0025] To ensure the reliability of the rotation of the limiting sleeve, a connecting rod 2.2 is coaxially provided at the lower end of the drive rod 2. The outer diameter of the connecting rod 2.2 is smaller than that of the drive rod 2. The limiting ring 4 is movably sleeved on the outside of the connecting rod 2.2. A retaining ring 2.4 fixed to the connecting rod 2.2 is provided below the limiting ring 4. The retaining ring 2.4 is provided with a retaining ring 2.43. The limiting ring 4 is rotatably sleeved on the outside of the retaining ring 2.43. The retaining ring 2.4 is provided to prevent the limiting ring 4 from falling off. Specifically, the end of the connecting rod 2.2 is provided with a locking hole 2.21 and a fixing groove 2.22 along its length. The fixing ring 2.4 is nested on the outside of the connecting rod 2.2 and is provided with a fastener 2.41 that cooperates with the locking hole 2.21. A fixing plate 2.42 is provided on the inside of the fixing ring 2.4. The fixing plate 2.42 is inserted into the fixing groove 2.22. The cooperation between the locking hole 2.21 and the fastener 2.41 facilitates the quick assembly of the fixing ring 2.4. At the same time, the cooperation between the fixing groove 2.22 and the fixing plate 2.42 increases the stability between the fixing ring 2.4 and the connecting rod 2.2.

[0026] To ensure reliable fixation of the electromagnet 5.1, a fixing bracket 1.24 is provided at both ends of the electromagnet 5.1 in the lower housing 1.2. The fixing bracket 1.24 is used to clamp and fix the electromagnet 5.1. The lower housing 1.2 is also provided with a wire hole 1.25 for connecting the electromagnet 5.1.

[0027] The specific working process of this utility model is as follows: Pressing the drive rod 22 causes it to move downwards. With the cooperation of the threaded groove 2.3 and the positioning pin 1.15, the drive rod 22 rotates simultaneously during its downward movement. Simultaneously, as the drive rod 2 moves downwards, it drives the limiting ring 4 to move downwards along the sliding groove 1.13. Due to the cooperation between the limiting block 5.21 and the sliding groove 1.13, the limiting ring 4 can only move vertically along the sliding groove 1.13. When the drive rod 2 continues to move downwards, it drives the limiting ring 4 to move downwards and disengage from the sliding groove 1.13. Continuing to press downwards, the limiting member 4.1 on the limiting ring 4 cooperates with the drive tooth 1.23, forcing the limiting ring 4 to rotate and shift. At this time, the limiting member 4.1 is aligned with the positioning groove 1.14. After the downward pressure on drive rod 2 is removed, drive rod 2 moves upward under the action of return spring 3. At this time, the retaining ring 2.4 moves upward with drive rod 2, and drives the limiting ring 4 to move upward synchronously, driving the limiting member 4.1 into the positioning groove 1.14. The limiting member 4.1 in the positioning groove 1.14 is restricted from moving upward, thereby achieving locking. When drive rod 2 is in the locked state, the locking hole 2.1 of drive rod 2 is aligned with the positioning pin 5.22. The sliding plug 5.2 is driven to move laterally by electromagnet 5.1, which in turn drives the positioning pin 5.22 to move laterally and insert into the locking hole 2.1, achieving electric locking and ensuring locking reliability. When unlocking is required, the positioning pin 5.22 is first driven laterally by electromagnet 5.1, that is, the positioning pin 5.22 is moved out of the locking hole 2.1. Then, press the drive rod 2, causing it to move downwards and simultaneously move the limiting ring 4 downwards. At this time, the limiting member 4.1 on the limiting ring 4 cooperates with the drive tooth 1.23 to force the limiting ring 4 to rotate and shift again. At this time, the limiting member 4.1 is aligned with the sliding groove 1.13. The downward pressure of the drive rod 2 is removed, and the drive rod 2 is pushed upwards by the return spring 3. The drive rod 2 drives the limiting ring 4 to move upwards along the sliding groove 1.13. At the same time, the drive rod 2 rotates in the opposite direction to reset while moving upwards with the cooperation of the positioning block 2.2 and the spiral groove, thus unlocking.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
