Detailed Implementation

[0025] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0026] Example 1

[0027] like Figures 1-7 As shown, the first bracket 5 is positioned to the body 11 using the first pin 10 and fastened to the first washer using the first screw 6. The support 8 is positioned and fastened to the body 11 using the second pin 21 and connected using the second screw 9, and damped by the pad 20. The electromagnet 4 is limited and installed to the support 8 using the second washer 16 and the second pin 15. The electromagnet 4 is connected to the pull rod 2 through the first pin 12 and the cotter pin 13, allowing the electromagnet 4 to move up and down. The pull rod 2 is fixed to the stop pin 1 using a square hole shaft. One end of the stop pin 1 is fixed in the body 11 and supported by the first spring 3. The end cap 17 provides limitation and support for the first spring 3 and is fastened to the body 11 using the third screw 18 and the third washer 19. The micro switch 23 is mounted on the first bracket 5 using the fourth screw 22 and is used to detect the position of the top rod 24 and the second bracket 25, respectively. The second bracket 25 is fixed to the stop pin 1 with screws. The locking pin 27 is installed inside the first bracket 5 and is supported and buffered by the second spring 28. The second nut 29 is used for adjustment and limiting. The locking shaft 34 is fixed to the locking pin 27 by a hole-shaft tight fit. The rotating arm 31 is installed on the shaft 35, and the sleeve 30 is installed on the shaft 35 to protect the shaft 35.

[0028] Specifically, the first support 5 has a symmetrical structure, and a baffle is provided behind the first support 5 to restrict the movement of the sleeve 30.

[0029] Specifically, the main body 11 is connected to the first bracket 5 by a threaded connection; a through hole and a threaded hole are provided on the main body 11, the through hole is used for the installation of the top rod 24, and the threaded hole is used for the mounting of the end cap 17.

[0030] Specifically, the support 8 is bolted to the body 11, and the pad 20 is used for vibration damping and adjustment. An electromagnet 4 is installed on the support 8 for raising and lowering the rod 2.

[0031] Specifically, the micro switch 23 is mounted on the first bracket 5 using the fourth screw 22, and is used to detect the position of the push rod 24 and the second bracket 25 respectively.

[0032] Example 2

[0033] The specific usage process of this organization is as follows:

[0034] When locked, a piece of equipment is loaded on a transport vehicle or transport cylinder. The handle is rotated by rotating the shaft 35 to rotate the arm 31, which in turn drives the locking shaft 27 to move horizontally. The second spring 28 is compressed, so that the stop pin 1 is in the extended state. The stop pin 1 drives the top rod 2 and the second bracket 25 to rise. The micro switch 23 detects the second bracket 25 and the back light comes on. At this time, the locking of the special equipment is completed.

[0035] When unlocking, when the special equipment moves, the electromagnet 4 is energized. Under the action of magnetic force, the pull rod 2 moves downward, and the two stop pins 1 also move downward with the pull rod 2. When the top rod 24 moves downward and contacts the micro switch 23, the micro switch indicator light lights up, indicating that the unlocking is in place. The locking pin 27 moves to the right under the action of the second spring 28 to achieve mechanical limit of the locking tongue. The rotating arm 31 rotates to the right under the pulling force of the locking pin 27, thereby achieving the unlocked state.
