Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerant storage tank technology, and more specifically, to a filling port sealing mechanism for a refrigerant storage tank. Background Technology
[0002] Refrigerant, also known as coolant or refrigerant, is a medium used in various heat engines to complete energy conversion. It increases power through reversible phase changes (such as gas-liquid phase changes) and is widely used in industrial and household appliances. Refrigerant actually needs to be stored in storage tanks. When using storage tanks, a sealing mechanism is required to seal the tank filling port. In practice, refrigerant has the advantages of simple operation, stable structure and good sealing effect.
[0003] The prior art discloses a reusable refrigerant storage tank with application number CN201921817155.9. In the above-mentioned utility model, the sealing of the liquid inlet of the storage tank requires the use of a sealing valve. The sealing valve needs to be connected to the liquid inlet and the liquid guiding pipe. There is no auxiliary structure. The operator needs to lift the sealing valve by hand and make multiple adjustments to align it. At the same time, the connection between the sealing valve and the liquid inlet and the liquid guiding pipe requires multiple bolt structures. After the alignment work is completed, the operator needs to insert multiple bolt structures through the installation hole one by one. This operation is quite cumbersome.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a sealing mechanism for the filling port of a refrigerant storage tank, which has the following advantages:
[0019] (1) This utility model adopts an installation box. When using the refrigerant storage tank filling port sealing mechanism, the operator moves the sealing valve by hand. When the sealing valve is moved between the storage tank filling port and the liquid guiding pipe, the operator rotates the two sets of mounting screws on the same side by hand, which can drive the one set of external gear rings on the same side to rotate. Since the one set of external gear rings on the same side and the two sets of driven gears on the same side mesh with each other, the rotating one set of external gear rings on the same side can drive the two sets of driven gears on the same side to rotate. The two sets of driven gears on the same side can drive the two sets of first bevel gears on the same side to rotate through the two sets of mounting shafts on the same side. Since the two sets of first bevel gears on the same side and the two sets of second bevel gears on the same side mesh with each other, the rotating two sets of first bevel gears on the same side can drive the two sets of second bevel gears on the same side to rotate. The two sets of second bevel gears on the same side can drive the two sets of lead levers on the same side to rotate. Since the two sets of lead levers and the two sets of lead screws on the same side The screw threads engage with each other, and the rotating two sets of screw levers on the same side can push the two sets of screw sleeves on the same side closer or further apart. The two sets of screw sleeves on the same side can bring the two sets of clamping seats on the same side closer together through the two sets of sleeve plates, the two sets of connecting rods, and the two sets of mounting plates on the same side. After the two sets of clamping seats on the same side clamp the filling port or liquid guide tube, the two sets of mounting screws and the two sets of threaded hole plates on the same side engage with each other. The operator rotates the two sets of threaded hole plates on the same side clockwise. When the two sets of threaded hole plates on the same side contact the mounting box on the same side, the external toothed ring on the same side is stably fixed, and the sealing valve is stably fixed, completing the alignment work. At this time, the sealing valve can be installed. The mounting box has an auxiliary structure, which facilitates the alignment work of the sealing valve and improves the practicality of the filling port sealing mechanism for refrigerant storage tanks.
[0020] (2) This utility model adopts a socket plate. According to the above operation, after the sealing valve is aligned, the operator can move away from the two sets of socket plates by hand. When one end of multiple sets of mounting bolts on the same side passes through multiple flange holes of a set of flanges on the same side, the installation work can be completed by using an external nut. When the two sets of socket plates are moved, multiple sets of balls roll inside multiple sets of ball sockets. The four sets of vertical rods can ensure the stability of the movement of the two sets of socket plates. Through the socket plate, it is convenient to complete the installation of multiple bolt structures, which brings convenience to the installation of the refrigerant storage tank filling port sealing mechanism.

[0037] In one embodiment, the threads of the two sets of levers 9 on the same side are in opposite directions.
[0038] Working principle:
[0039] When actually using the refrigerant storage tank filling port sealing mechanism, the operator manually moves the sealing valve 1. When the sealing valve 1 is moved between the storage tank filling port and the liquid guiding pipe, the operator manually rotates the two sets of mounting screws 18 on the same side, which can drive the one set of external gear rings 5 on the same side to rotate. Since the one set of external gear rings 5 on the same side and the two sets of driven gears 7 on the same side mesh with each other, the rotating one set of external gear rings 5 on the same side can drive the two sets of driven gears 7 on the same side to rotate. The two sets of driven gears 7 on the same side can drive the two sets of first bevel gears 8 on the same side to rotate through the two sets of mounting shafts 6 on the same side. Since the two sets of first bevel gears 8 on the same side and the two sets of second bevel gears 8 on the same side mesh with each other, the two sets of driven gears 7 on the same side can drive the two sets of driven gears 7 on the same side to rotate. The bevel gears 13 mesh with each other. The rotating first bevel gears 8 on the same side can drive the two sets of second bevel gears 13 on the same side to rotate. The two sets of second bevel gears 13 on the same side can drive the two sets of lead levers 9 on the same side to rotate. Since the two sets of lead levers 9 and the two sets of lead screw sleeves 10 on the same side are threadedly engaged, the rotating two sets of lead levers 9 on the same side can push the two sets of lead screw sleeves 10 on the same side closer or further apart. The two sets of lead screw sleeves 10 on the same side can bring the two sets of clamping seats 16 on the same side closer together through the two sets of sleeve plates 11, the two sets of connecting rods 14, and the two sets of mounting plates 15 on the same side. When the two sets of clamping seats 16 on the same side are engaged... After the filling port or liquid guiding tube is clamped, the two sets of mounting screws 18 and two sets of threaded hole plates 19 on the same side engage with each other. The operator manually rotates the two sets of threaded hole plates 19 clockwise. When the two sets of threaded hole plates 19 contact the mounting box 2 on the same side, the external toothed ring 5 on the same side is stably fixed, and the sealing valve 1 is stably fixed, completing the alignment work. At this time, the installation work of the sealing valve 1 can be carried out. The mounting box 2 has an auxiliary structure, which facilitates the alignment work of the sealing valve 1, improves the practicality of the filling port sealing mechanism for refrigerant storage tanks, and at the same time, according to As can be seen from the above operation, after the sealing valve 1 is aligned, the operator can move their hands away from the two sets of socket plates 3. When one end of multiple sets of mounting bolts 24 on the same side passes through multiple flange holes of a set of flanges 4 on the same side, the installation work can be completed using external nuts. When the two sets of socket plates 3 are moved, multiple sets of balls 23 roll inside multiple sets of ball sockets 22 respectively. The four sets of vertical rods 20 can ensure the stability of the movement of the two sets of socket plates 3. Through the socket plates 3, the installation work of multiple bolt structures can be easily completed, which brings convenience to the installation work of the refrigerant storage tank filling port sealing mechanism.
