Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See Figure 1 An electronic device locking device includes a quick-lock pin 35, which comprises a pin sleeve 351, a pin return spring 352, a pin 353, a pin core return spring 354, a pin core 355, a lock 356, a connecting rod 357, a handle 358, and an end cap 359. The quick-lock pin 35 has two states: a retracted state and an extended state. The pin sleeve 351 is fixedly connected to the end face of an object to be fixed, and one end of the pin sleeve 351 is a bevel. The handle 358... 58 is fixed to the pin 353. The handle 358 abuts against the inclined surface of the pin sleeve 351, serving as a limit between the pin sleeve 351 and the pin 353. The end cap 359 is fixedly connected to the top of the handle 358 and to the pin 353, serving as a limit for the handle 358. The pin 353 is rotatably disposed within the pin sleeve 351 and is elastically connected to the pin 353 via a pin return spring 352. A top ring 3511 is fixedly connected to the inner wall of the pin sleeve 351. (See reference...) Figure 2The outer wall of the pin 353 is formed with an outer step 3531 that is always located below the plane of the top ring 3511. The top ring 3511, the inner wall of the pin sleeve 351, the outer step 3531 and the pin 353 enclose the installation gap of the pin return spring 352. The top of the pin return spring 352 is fixedly connected to the top ring 3511. The top of the pin return spring 352 is rotatably fixed to the top surface of the outer step 3531 of the pin 353. Since the top surface of the pin 353 is inclined, when the pin 353 is rotated by the handle 358, the pin 353 can be retracted and extended relative to the pin sleeve 351.

[0027] See Figure 3 and Figure 4 The pin 353 has at least two lock holes 3533, which are taken as examples in this embodiment. The lock holes 3533 are evenly distributed around the circumference. A lock 356 is slidably fitted in the lock holes 3533. When the pin 353 is in the extended state, the lock 356 extends out of the pin 353 through the lock holes 3533. The pin return spring 352 is used to hold and return the pin 353. A pin core 355 is slidably connected in the pin 353 and is spring-loaded with the pin core 355 by the pin core return spring 354. The connection allows the pin 355 and pin body 353 to slide relative to each other. The outer wall of the pin 355 has an integrally formed pin ring 3551, and the inner wall of the pin body 353 has an internal step 3532. The internal step 3532 is located below the plane of the pin ring 3551. The pin ring 3551, the inner wall of the pin body 353, the top surface of the internal step 3532, and the outer wall of the pin 355 together form the movement gap of the pin return spring 354. One end of the pin 355 is a pressing end, and the other end is a narrow, tapered rod. (See reference...) Figure 5 The narrow rod is movably connected to the lock 356 via a connecting rod 357. One end of the connecting rod 357 is hinged to the lock 356, and the other end is hinged to the narrow rod. Pressing the pressing end of the pin 355 causes the pin 355 to move downward, causing the connecting rod 357 to rotate, thereby driving the lock 356 to slide in the lock hole. The lock 356 retracts back into the lock hole. Releasing the pressing end of the pin 355 causes the pin 355 to spring up under the action of the pin return spring 354, and the lock 356 extends out of the lock hole. It should be noted that the handle 358 has anti-slip threads.

[0028] How to use:

[0029] Insert the quick-lock pin 35 into the through holes on the two objects to be fixed. The bottom of the pin sleeve 351 is in contact with the end face of the object to be fixed on one side. Rotate the pin body 353 by turning the handle 358 to make the pin body 353 extend out of the pin sleeve 351. Press the pin core 355 to make the two locks 356 extend out of the pin body 353. Release the pin core 355 and the pin body 353 to fix the two objects to be fixed.

[0030] Pressing the pin 355 of the quick-lock pin 35 causes the lock 356 to retract into the pin body 353, releasing the vertical limit. At the same time, rotating the handle 358 rotates the pin body 353, causing the pin body 353 to be in a retracted state, releasing the limit on the two objects to be fixed, allowing them to move relative to each other.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
