[0028] See also Figure 1 The embodiment of the present application provides a sterilization device cover locking device, including a locking pin, a cylinder, a locking fork, and a mounting seat. The mounting seat is fixed on the sterilization device; the cylinder is arranged on the mounting seat; the locking fork is fixed on the piston rod of the cylinder; the locking pin is fixed on the top cover of the sterilization device; when the top cover is locked, the locking pin is clamped on the locking fork.

[0029] Before locking the top cover of the sterilization device, the piston rod of the cylinder is in a stationary state, so that the locking fork on the piston rod is stationary. At this time, the locking pin rotates with the top cover until the locking pin is inserted into the locking fork. At this time, the cylinder gives the piston rod an extension force (the direction of the locking force is to the left), so that the locking fork presses against the locking pin, and then locks the locking pin, thereby locking the top cover. When the top cover is to be opened, the cylinder gives the piston rod a contraction force, so that the piston rod of the cylinder contracts, and then the locking fork and the locking pin are disengaged, and then the top cover is released to achieve automatic unlocking. The device has a simple structure, is firm and reliable during use, is easy to operate, does not require manual intervention, and greatly improves the convenience of use.

[0030] In one embodiment, two locking forks and two locking pins are included, the two locking forks are connected by a connecting rod, and the spacing between the locking pins is the same as the spacing between the locking forks. By providing two locking forks and two locking pins to lock the top cover, the locking stability is improved.

[0031] In one embodiment, a connecting rod cover is further included, one end of which is fixed on the mounting seat, and the connecting rod cover is arranged on the periphery of the connecting rod.

[0032] In one embodiment, a terminal head is disposed at the other end of the connecting rod cover.

[0033] In one embodiment, the cylinder is connected with an air pipe joint, the mounting seat is provided with a joint fixing seat, and the air pipe joint is installed and fixed on the joint fixing seat.

[0034] In one embodiment, the cylinder is a single-acting spring-reset cylinder. By using a single-acting spring-reset cylinder, the resetting force given to the piston rod by the elastic member (spring) in the cylinder can be used to lock the locking pin, so that the locking device can lock the top cover without power or air pressure, avoiding the phenomenon of loosening due to power or air failure of the locking device.

[0035] When the locking device needs to be opened, air is simply ventilated into the cylinder through the air pipe joint, and the air pressure is used to overcome the elastic force of the elastic member in the cylinder, causing the piston rod to contract, so that the lock fork and the lock pin can be disengaged for unlocking.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
