Description

Refrigerant filling start-stop device with pressure monitoring function Technical Field The utility model relates to the technical field of refrigerant filling devices, in particular to a refrigerant filling start-stop device with pressure monitoring. Background In the technical field of refrigerant filling, a refrigerant filling start-stop device with pressure monitoring is key equipment for realizing accurate control of refrigerant filling quantity, and pressure data in a filling process can be fed back in real time through an integrated pressure monitoring function, so that the safety and efficiency of filling operation are ensured. When the refrigerant is filled, the pressure filling valve is required to be temporarily fixed, so that the operations such as pipeline connection, parameter adjustment and the like can be conveniently performed manually. The hanging structure of the existing device adopts a simple hook or binding band mode, is difficult to form multi-point clamping, is difficult to stably position, is easy to fall down due to external force collision or vibration, is easy to clamp or loosen in part of the hanging structure, and has potential safety hazards. Disclosure of utility model The utility model aims to provide a refrigerant filling start-stop device with pressure monitoring so as to solve the technical problem that a pressure filling valve cannot be stably fixed in the process of filling a refrigerant. In order to achieve the purpose, the utility model provides the technical scheme that the refrigerant filling start-stop device with the pressure monitoring function comprises a pressure filling valve, wherein a hanging component for hanging the pressure filling valve is arranged at the upper end of the pressure filling valve. The hanging component comprises a hanging rope fixedly installed at the upper end of the pressure filling valve, the upper end of the hanging rope is fixedly connected with a limiting seat, a limiting groove is formed in one side of the limiting seat, a reset spring is fixedly connected to the other side of the limiting seat, a transmission plate is fixedly connected to the other end of the reset spring, two sleeves are fixedly connected to one side of the transmission plate, extrusion blocks are symmetrically arranged on the inner walls of the two sleeves, transmission rods are symmetrically arranged on the upper end of the limiting seat in a rotating mode, clamping shafts are fixedly connected to one end of each transmission rod, and the other end of each transmission rod is provided with the corresponding extrusion groove. As a preferable scheme of the utility model, the extrusion groove is of an inclined structure, and the extrusion block is in sliding connection with the extrusion groove. As a preferable scheme of the utility model, the limit seat is of a rectangular structure. As the preferable scheme of the utility model, the limit groove is of a cross structure, and the corners of the limit groove are chamfered. As a preferable scheme of the utility model, the hanging rope is made of braided belts, and two ends of the hanging rope are respectively and fixedly connected with the upper end of the pressure filling valve and the lower end of the limiting seat in an injection molding or hot pressing mode. Compared with the prior art, the refrigerant filling start-stop device with pressure monitoring has the beneficial effects that the limiting groove is accurately inserted into the fixed position through the cooperation of the limiting seat, the clamping shaft and the reset spring, the clamping shaft is automatically reset and clamped after the transmission plate is loosened by utilizing the sliding transmission of the extrusion block and the inclined extrusion groove, the multi-angle stable clamping of the fixed position is formed, the device is prevented from shaking or falling off in the hanging process, and the convenience and the safety of hanging and holding of the pressure filling valve in the refrigerant filling process are effectively improved.
