[0023] A cavity is provided inside the cover plate 3, and bosses are provided on both sides of the cavity. A pin hole is provided inside the boss, and a pin 9 is provided inside the pin hole. A spring is sleeved on the pin 9. A spring hole is provided inside the cover plate 3 perpendicular to the direction of the boss, and a plug 12 is provided at the bottom of the spring hole. The slider 6 is set in the cavity, with wedge-shaped sides that contact the pin 9. The other end of the spring connected to the end of the slider 6 is set in the spring hole. The top of the slider 6 is provided with a connecting protrusion. The handle 1 is rotatably connected to the connecting protrusion through the crossbar 4. It is used to drive the slider 6 to slide back and forth against the spring force in the spring hole, and push the pin 9 to extend or retract from the cover plate 3 against the spring force of the sleeve, so as to lock or release it with the groove at the structure to be installed, thereby achieving locking or disassembly. The upper cover plate 2 is positioned above the cover plate 3, and a slider groove is provided on it for the connecting protrusion to slide. The sealing gasket pressure plate 10 is connected below the cover plate 3.

[0024] For example, the handle 1 is fixed to the slider 6 by the crossbar 4. The slider 6 is fixed in the cavity formed by the upper cover plate 2 and the cover plate 3, and the spring 13 is placed at the slider 6 and the pin 9.

[0025] Optionally, a limit snap ring 8 is provided at one end of the slider groove on the upper cover plate 2 adjacent to the spring hole to limit the handle 1 after locking; Optionally, the elastic stop 7 is U-shaped, with its bottom fixed at the end of the slider groove on the upper cover plate 2 away from the spring hole, and its two arms are raised upward and arranged toward the limiting snap ring 8, with the height of the two arms being higher than the crossbar 4. Both ends of the handle 1 are fixedly connected to the side of the elastic stop 7 with unlocking pins 5; When locking, pull handle 1 causes unlocking pin 5 to press down the two arms of elastic block 7. At this time, crossbar 4 is higher than elastic block 7, so that handle 1 moves to the locking position under the action of spring 13 and locks.

[0026] The elastic stop 7, the limiting snap ring 8, and the upper cover plate 2 are fixed to the cover plate 3 by screws 14; the sealing gasket pressure plate 10 is fixed to the cover plate 3 by pins 15, and the bottom is glued with a sealing gasket 11 for sealing.

[0027] The sealing device can be installed into a structure with a specific slot by pressing and rotating the handle. After installation, the handle can be locked in the limit spring to prevent the sealing device from unlocking.

[0028] The key points of this invention are as follows: a. The sealing device can be quickly installed and removed by pressing and rotating the handle; b. After installation, lock the sealing device using the handle; c. The sealing device is designed with a sealing structure to prevent water from entering the machine body.

[0029] For example, the assembly steps of the device provided by the present invention include: 1. The sealing gasket 11 is bonded to the sealing gasket pressure plate 10, and the sealing gasket pressure plate 10 is fixed to the bottom of the cover plate 3 by the pin 15; 2. Install two spring-loaded pins 9 at the pin holes of the boss on the cover plate 3, and install two short pins 16 at the short pin through holes next to the boss. 3. Place the spring 13 in the inner hole of the slider 6, and then place the whole thing in the cavity of the cover plate 3. Align the spring 13 with the spring hole at the cover plate 3 perpendicular to the boss. Install the plug 12 on the other side of the spring hole. 4. The upper cover plate 2 slide groove is aligned with the slide 6 and placed on the cover plate 3. It is connected to the cover plate 3 together with the elastic stop block 7 and the limit snap ring 8 through screws 15. 5. Two unlocking pins 5 are fixed in the through holes on both sides of the handle 1, and then fixed to the slider 6 by the crossbar 4.

[0030] In this embodiment of the invention, the opening of the structure is slotted according to the size of the pin 9.

[0031] During installation, align the short pin 16 of the sealing device with the slotted hole, and rotate the handle 1 to screw the sealing device into the structural opening.

[0032] After the sealing device is installed, press down the handle 1. The spring 13 inside the slider 6 will push the slider 6 and the handle to slide along the slider groove. After sliding to the bottom, press the handle in the opposite direction to lock the handle inside the limit spring 8. The pin 9 pops out and locks in the slotted hole of the structure. The sealing device is now installed.

[0033] During disassembly, pull up the handle 1 from the limit spring 8, then pull the handle along the slider groove. After pulling to the bottom, the pin 9 is pressed back into the cover plate groove by the spring. Rotate the handle to remove the sealing device.
