[0027] Please see Figure 3 and Figure 4 As shown, the sliding rod 14 is threadedly connected to the middle of the operating rod 4; the surface of the operating rod 4 is arc-shaped; the operating rod 4 is installed on the surface of the sliding rod 14, and when the cabinet door 12 needs to be unlocked, the operating rod 4 can be pressed to control the card plate 17. At the same time, because the surface of the operating rod 4 is prone to dirt or coating peeling due to long-term pressing, when the operating rod 4 needs to be replaced, it can be removed from the surface of the sliding rod 14 by rotating the operating rod 4, so as to realize the quick replacement of the operating rod 4 by the device.
[0028] Please see Figure 4 As shown, a plurality of protrusions 5 are fixedly connected to the middle of the operating lever 4; the protrusions 5 are filled in; by setting the protrusions 5, the surface friction coefficient of the operating lever 4 will be greater when it is replaced, thereby improving the convenience of replacing the operating lever 4.
[0029] Please see Figure 1 and Figure 2As shown, a sponge 6 is fixedly attached to the middle of the handle 13; the sponge 6 is located on one side of the cabinet body 1; the cabinet door 12 can be rotated through the handle 13. Since the palms of the workers' hands are prone to sweat or other liquids when working, the sponge 6 can absorb these liquids and improve the stability of the handle 13 when operating.
[0030] Working principle: When cabinet door 12 needs to be unlocked, the slide bar 14 can be pulled to make the latch 17 slide along the first slide groove 16. The first spring 15 will be compressed accordingly, and the latch 17 will slide out of the slot in the middle of the cabinet door 12, making the cabinet door 12 in an open state. At the same time, when the latch 17 moves, the crank 18 will slide along the second slide groove 19 until the crank 18 slides to the concave part of the surface of the second slide groove 19. At this time, the latch 17 will be fully inserted into the first slide groove 16, and the cabinet body 1 will be in a fully unlocked state, and the cabinet door 12 can be opened and closed freely. When the door 12 is locked, after rotating the cabinet door 12 to close the cabinet body 1, the slide bar 14 can be pressed to make the crank 18 slide along the second slide groove 19 to the protrusion. At this time, the locking plate 17 will slide out of the first slide groove 16 and enter the locking groove in the cabinet door 12, realizing the device to quickly lock the cabinet door 12. During the rotation of the cabinet door 12, the cabinet door 12 can be operated by the handle 13. When the locking plate 17 slides along the first slide groove 16, the slider 22 will be pressed tightly against the surface of the locking plate 17 under the elastic force of the second spring 24, and the elastic cloth 2 will move together with the slider 22. The gap between the card plate 17 and the first slide groove 16 is shielded to reduce the amount of dust and impurities entering the first slide groove 16. Simultaneously, the ball bearing 23 contacts and rotates with the card plate 17, reducing wear caused by friction between the slider 22 and the card plate 17. The sealing strip 3 seals the gap between the slider 22 and the card plate 17, further improving the sealing performance and reducing the entry of external impurities into the first slide groove 16. Installing the operating lever 4 on the surface of the slide rod 14 requires disassembling the cabinet door 12. When locking, the locking plate 17 can be operated by pressing the operating lever 4. However, since the operating lever 4 is prone to dirt or coating peeling due to long-term pressing, it can be removed from the slide bar 14 by rotating it when it needs to be replaced. The protrusion 5 increases the surface friction coefficient of the operating lever 4 when it is replaced. The cabinet door 12 can be rotated by the handle 13. Since the palms of the workers are prone to sweat or other liquids during work, the sponge 6 can absorb these liquids and improve the stability of the handle 13 when operating.
