[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-4As shown, the utility model provides a suction cup structure that can quickly release gas, and the suction cup structure specifically includes a valve switch valve core 1 and a valve sleeve 2, the valve sleeve 2 is sleeved on the outer wall of the valve switch valve core 1, and a limit rod 4 is threadedly connected above the valve switch valve core 1, and a rotating block 3 is fixedly connected to the top of the limit rod 4, and two first sealing rings 8 are fixedly connected to the inner wall of the valve sleeve 2, and the first sealing ring 8 can complete the sealing work, and a pressure relief groove 7 is provided on the inner wall of the valve switch valve core 1, and a connecting end 9 is integrally provided at the bottom end of the valve switch valve core 1, and a second sealing ring 10 is sleeved on the outer wall of the top end of the connecting end 9, and the second sealing ring 10 can ensure the sealing of the connection at the connecting end 9. The utility model aims to provide a LCD TV screen suction device with excellent performance, safety and reliability, and simple operation. When disassembling, the staff does not need to use external tools. When operating, the air flow of the pressure relief groove 7 can be opened and closed by sliding the valve sleeve 2 up and down, so as to realize the easy switching between the sealing and non-sealing of the suction cup, thereby facilitating the staff to disassemble it and improving the overall practicality of the suction cup structure.

[0023] The valve switch valve core 1 is clamped with a spring washer on the outer wall of the bottom end, and the spring washer can limit the valve sleeve 2 moving downward to prevent vibration and slippage.

[0024] As an implementation mode, the outer wall of the connection end 9 is distributed with threads, and the middle part of the connection end 9 is hollow for air circulation.

[0025] As an implementation method, the pressure relief groove 7 is designed in a “T”-shaped structure, and the pressure relief groove 7 can guide air into the suction cup body 5 .

[0026] As an implementation mode, a connecting sleeve 6 is integrally provided above the suction cup body 5, the connecting sleeve 6 is threadedly connected to the connecting end 9, the inner wall of the connecting sleeve 6 is clamped with a metal pancake structure, and the connecting end 9 is threadedly connected to the metal pancake.

[0027] As an implementation method, the inner wall size of the two first sealing rings 8 fits the outer wall size of the valve switch valve core 1. The two first sealing rings 8 make the outer end opening of the pressure relief groove 7 in a sealed state, and the sealing state can be released by sliding the valve sleeve 2 upward.

[0028] As an implementation mode, the outer wall of the limit rod 4 is distributed with threads, and the limit rod 4 and the valve switch valve core 1 are threadedly connected, and the structure can be connected to the external bracket by rotating the rotating block 3.

[0029] As an implementation method, the cross section of the valve switch valve core 1 is designed as a T-shaped structure.

[0030] Working principle:

[0031] When the suction cup structure that can quickly release gas is in use, the valve switch valve core 1 is first connected to the external bracket, and the limiting rod 4 can be used to insert the bracket, and then the rotating block 3 is rotated after being threadedly connected to the valve switch valve core 1. The valve switch valve core 1 limits the screen through the suction cup body 5. The staff only needs to push the valve sleeve 2 upward. When it moves to the top, the height of the first sealing ring 8 on the bottom side is higher than the outer port of the pressure relief groove 7, so that the air enters the connecting end 9 from the pressure relief groove 7, and then the connecting end 9 enters the suction cup body 5 under the connecting sleeve 6, completing the rapid disassembly and assembly work.
