[0028] See also Figure 1 to Figure 2 As shown, the utility model provides a convenient anti-overflow liquid device, including a connecting sleeve 7, a sealing cover 1, and a sealing flange 2;

[0029] The connecting sleeve 7 is fixedly connected to the device to be injected, and a liquid inlet 6 is provided on the top;

[0030] The sealing cover 1 is installed on the top of the connecting sleeve 7, and a cavity is provided inside the sealing cover 1, and the bottom of the cavity is connected to the liquid inlet 6; the top of the sealing cover 1 is also provided with a liquid injection port 8;

[0031] The sealing flange 2 is disposed inside the cavity of the sealing cover 1 and can be elastically lifted and lowered relative to the connecting sleeve 7 to achieve sealing closure or liquid injection opening of the liquid injection port 8 of the sealing cover 1 .

[0032] Specifically, see Figure 1 to Figure 2 As shown, the portable anti-overflow liquid injection device includes a sealing cover 1, a sealing flange 2, a positioning shaft 3, a spring 4, a sleeve 5, a liquid inlet 6, a connecting sleeve 7, a liquid injection port 8, and a liquid injection pipe connecting portion 9.

[0033] The sealing cover 1 is a cover structure with a downward opening, comprising a cover shell, a containing space arranged inside the cover shell, i.e., a cavity, and a liquid injection port 8 arranged at the top of the cover shell. The cavity is fixedly connected to the top of the connecting sleeve 7, and they enclose each other to form a closed liquid injection cavity.

[0034] The liquid injection port 8 arranged on the top of the sealing cover 1 can be sealed and closed by the sealing flange 2, thereby preventing the solution in the box of the device to be injected from overflowing during movement.

[0035] The inner diameter of the liquid injection port 8 is larger than the outer diameter of the liquid injection tube.

[0036] In some specific embodiments, the shaft sleeve 5 is installed at the top center of the connecting sleeve 7, and the liquid inlet 6 is distributed around the shaft sleeve 5. In addition, the cavity of the sealing cover 1 covers the shaft sleeve 5 and the liquid inlet 6, and is connected to the connecting sleeve 7 and encloses each other.

[0037] The connecting sleeve 7 is provided with structures such as threads or flanges, and is used for fixed connection with the water tank waiting for liquid injection device.

[0038] The sealing flange 2 and the shaft sleeve 5 are connected by sliding up and down through the positioning shaft 3 ; the bottom of the sealing flange 2 is threadedly connected to the top of the positioning shaft 3 .

[0040] The top of the sealing flange 2 is provided with an injection pipe connecting portion 9 , which is a protruding rib structure or a groove structure, and is used to allow the solution to be injected from the cavity between the sealing flange 2 and the sealing cover 1 .

[0041] After the injection pipe contacts the top of the sealing flange 2, it will continue to press downward to inject the liquid from the cavity. The protruding rib plate or groove (injection pipe connection part 9) is provided on the top of the flange to ensure that there is always a gap between the injection port 8 and the top surface of the sealing flange 2 to prevent the injection port 8 from being blocked by the plane of the sealing flange 2, thereby ensuring the smoothness of the injection.

[0042] In a non-working state, the sealing flange 2 is sealedly connected to the sealing cover 1 to close and seal the liquid injection port 8 .

[0043] When in working state, the injection tube abuts against the injection tube connecting portion 9 arranged on the sealing flange 2, and the sealing flange 2 elastically slides downward relative to the connecting sleeve 7. The liquid in the injection tube is injected into the cavity through the injection tube connecting portion 9 and finally flows to the liquid inlet 6, thereby preventing the liquid from overflowing.

[0044] The working mechanism of the convenient anti-overflow liquid device provided by the utility model is:

[0045] During operation, the injection pipe is inserted into the injection port 8 of the sealing cover 1, and the injection pipe abuts against the injection pipe connection portion 9 provided on the sealing flange 2, so that the sealing flange 2 slides downward. Then, the injection pipe starts to inject liquid, and the liquid is injected through the cavity between the sealing cover 1 and the sealing flange 2, and enters the liquid injection device box through the liquid inlet 6 on the connecting sleeve 7, so that the liquid can be easily injected.

[0046] After the liquid is filled, as the injection tube is pulled out from the injection port 8 of the sealing cover 1, the sealing flange 2 moves upward under the elastic force of the spring 4 to seal the injection port 8 of the sealing sleeve 1, thereby achieving the effective effect of preventing the solution from overflowing during moving or swinging operations.

[0047] When not in operation, due to the elastic force of the spring 4 , the sealing flange 2 and the sealing cover 1 are always in a sealed connection state to close and seal the liquid injection port 8 .

[0048] The convenient anti-overflow liquid injection device provided by the utility model is provided with a combined structure of a sealing cover, a sealing flange and a connecting sleeve, etc., and utilizes the enclosed cavity structure between the sealing cover and the connecting sleeve to realize a buffer accommodating space for liquid injection; utilizes the elastic sliding connection structure between the sealing flange and the connecting sleeve to realize the sealed closure and liquid injection opening of the sealing cover liquid injection port; utilizes the communication structure design between the sealing cover cavity and the liquid inlet of the connecting sleeve, so that the injected liquid in the cavity finally flows to the liquid inlet and enters the interior of the device to be injected; thereby, it is achieved that the injected liquid does not overflow during the movement process such as moving or swinging, and convenient liquid injection can be realized.

[0049] In summary, the utility model provides a convenient anti-overflow liquid injection device, which relates to technical fields such as gold mines and environmental protection management of tailings dust, and includes a connecting sleeve, a sealing cover, and a sealing flange; the connecting sleeve is fixedly connected to the device to be injected, and a liquid inlet is arranged on the top; the sealing cover is installed on the top of the connecting sleeve, and a cavity is arranged inside the sealing cover, and the bottom of the cavity is connected to the liquid inlet; the top of the sealing cover is also provided with a liquid injection port; the sealing flange is arranged inside the cavity of the sealing cover, and can be elastically lifted and lowered relative to the connecting sleeve to achieve the sealing closure or liquid injection opening of the sealing cover liquid injection port.
