[0002] The refrigerant recovery and filling machine is a machine integrating multiple functions such as recovery, regeneration, filling, leak detection, vacuum pumping, and filling of refrigerating oil. Refrigerant recovery: Rely on the compression and filtration device inside the machine system to recover the refrigerant in the air-conditioning pipeline into the working tank. Refrigerant regeneration: It can separate the refrigerating oil and moisture in the air-conditioning system to meet the reuse standard, ensure the purity of the refrigerant, so that the refrigerant can be recycled. Refrigerant filling: Set the amount of refrigerant to be filled and add the corresponding amount of the same type of refrigerant to the vehicle.

[0003] The lower plate structure of the refrigerant filling machine is assembled at the bottom of the main body of the refrigerant filling machine, and is used to control the flow direction of liquid and gas according to the use requirements of the equipment. However, the assembly method of the existing lower plate structure and the refrigerant filling machine is mostly cumbersome, the disassembly and assembly are not convenient enough, and the assembly stability is poor. The bottom plate does not have good shock absorption performance. During the filling process, it is easily affected by external impacts or vibrations and affects the normal operation. Therefore, it is necessary to propose a lower plate structure in the main body module of the refrigerant filling machine to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lower plate structure in the main body module of a refrigerant filling machine, which has the effects of convenient assembly, stable structure, and good shock absorption performance.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A lower plate structure in the main body module of a refrigerant filling machine, including a workbench and a lower plate main body arranged above the workbench. A shock absorption component is installed between the workbench and the lower plate main body. The upper end surface of the lower plate main body is installed with a refrigerant filling machine main body and an assembly component for fixing the refrigerant filling machine main body. The assembly component includes a round table arranged on the upper end surface of the lower plate main body and a circular installation groove concentric with the round table. A rotating ring located on the outer wall of the circular installation groove is rotatably arranged in the circular installation groove. Two fixing columns and four openings are installed on the rotating ring. Four openings corresponding to the position of the rotating ring are arranged on the refrigerant filling machine main body. Four resilient pins passing through the rotating ring and inserted into the openings of the refrigerant filling machine main body are circumferentially installed on the round table. A card slot for the fixing column to be embedded is also arranged at the bottom of the refrigerant filling machine main body.

[0006] By adopting the above technical solution, the bottom of the refrigerant filling machine main body is inserted into the circular installation groove, so that the two positioning posts on the rotating ring are embedded into the card slots. By rotating the refrigerant filling machine main body counterclockwise, the rotating ring is driven to rotate, making the resilient latch correspond to the opening. The resilient latch extends and penetrates through the opening on the outer wall of the refrigerant filling machine main body, thereby installing the refrigerant filling machine main body on the lower plate main body. The whole assembly process is very convenient and facilitates subsequent maintenance and disassembly.

[0007] A further setting of the present utility model is that: the resilient latch includes four limit pins slidably arranged on the outer peripheral wall of the frustum, and a return spring connecting the inner wall of the frustum is arranged at one end of the limit pin far away from the opening.

[0008] By adopting the above technical solution, when the limit pin corresponds to the opening position, the return spring compresses and rebounds the limit pin through the inner wall of the refrigerant filling machine main body.

[0009] A further setting of the present utility model is that: a limit block slidably connected to the frustum is installed at the end of the limit pin, and four guide rods slidably connected to the limit block are also arranged in the frustum.

[0011] A further setting of the present utility model is that: four threaded holes are arranged on the upper end surface of the lower plate main body and are located on the outer periphery of the refrigerant filling machine main body. Four positioning blocks corresponding to the positions of the threaded holes and positioning columns passing through the positioning blocks and being threadedly inserted into the threaded holes are installed on the outer wall of the refrigerant filling machine main body.

[0012] By adopting the above technical solution, after the refrigerant filling machine main body is installed, then the four positioning columns are vertically passed through the positioning blocks and screwed into the threaded holes, thereby further positioning the installation of the refrigerant filling machine main body, which can greatly improve the installation stability of the refrigerant filling machine main body.

[0013] A further setting of the present utility model is that: two gas-liquid conduits accessing the refrigerant filling machine main body are arranged on the side surface of the lower plate main body, and an interface for installing a flow valve is arranged above the gas-liquid conduits.

[0014] By adopting the above technical solution, the external equipment pipeline is connected by the gas-liquid conduit, thereby realizing the transportation of gas-liquid raw materials. After installing the flow valve, it is convenient to control the input amount of raw materials.

[0015] A further setting of the present utility model is that the shock-absorbing component includes two fixing plates symmetrically arranged front and back on the upper end surface of the workbench.

A first shock-absorbing main body and a second shock-absorbing main body are provided at the bottom of the lower plate body.

[0016] By adopting the above technical solution, the first shock-absorbing main body and the second shock-absorbing main body perform shock-absorbing treatment. While shock-absorbing, during the sliding process of the lower plate body, the sliders on both sides slide in the chutes, improving the earthquake resistance performance.

[0017] A further setting of the present utility model is that the first shock-absorbing main body includes a plurality of first elastic dampers hinged to both sides of the bottom of the lower plate body, and a connecting frame for connecting the other ends of the first elastic dampers is hinged on the fixing plate.

[0018] By adopting the above technical solution, when affected by external impacts or vibrations, the workbench pushes the connecting frame to slide, squeezing the first elastic dampers, and performing shock absorption through the action of the plurality of first elastic dampers, thereby enhancing the working stability of the lower plate body and the refrigerant filling machine body.

[0019] A further setting of the present utility model is that a retaining piece is installed on the outer wall of the first elastic damper and the end of the connecting frame, and a first spring is installed between the two retaining pieces.

[0020] By adopting the above technical solution, while the first elastic damper is compressed, the two retaining pieces will squeeze the first spring, which can further enhance the shock-absorbing effect on both sides.

[0021] A further setting of the present utility model is that the second shock-absorbing main body includes a connecting block installed on the opposite sides of the workbench and the lower plate body, and a second spring is installed between the two connecting blocks.

[0022] By adopting the above technical solution, while the workbench pushes and presses the connecting frame, the two connecting blocks approach each other, compressing the second spring, and performing shock absorption on the middle area.

[0023] A further setting of the present utility model is that the connecting block is a rubber shock-absorbing block, and second elastic dampers are further provided around the periphery between the two rubber shock-absorbing blocks.

[0024] By adopting the above technical solution, the setting of the rubber shock-absorbing block and the second elastic damper can further increase the shock-absorbing effect on the middle area between the workbench and the lower plate body, making the overall shock-absorbing performance better.

[0025] The beneficial effects of the present utility model are:

[0026] 1. In this utility model, by inserting the bottom of the refrigerant filling machine main body into the circular installation groove, the two positioning posts on the rotating ring are embedded into the card slots. By rotating the refrigerant filling machine main body counterclockwise, the rotating ring is driven to rotate. When the limit pin corresponds to the opening position, the return spring compresses and rebounds the limit pin, making it pass through the inner wall of the refrigerant filling machine main body, and quickly installing the refrigerant filling machine main body on the lower plate main body. Then, the four positioning posts are vertically passed through the positioning blocks and screwed into the threaded holes, thereby further positioning the installation of the refrigerant filling machine main body, which can greatly improve the installation stability of the refrigerant filling machine main body. The entire assembly process is very convenient, facilitating subsequent maintenance and disassembly.

[0027] 2. In this utility model, when the device is affected by external impacts or vibrations, the workbench pushes the connecting frame to slide, squeezing the first elastic damper. The two retaining plates will squeeze the first spring. Through the cooperation of multiple groups of first elastic dampers and first springs, the shock absorption performance on both sides of the bottom of the lower plate main body can be greatly improved. When the workbench pushes and presses the connecting frame, the two connecting blocks approach, squeezing the second spring and the second elastic damper. At the same time, the connecting blocks are made of rubber shock-absorbing blocks, which can further enhance the shock absorption effect in the middle area between the workbench and the lower plate main body, making the overall shock absorption performance better and making the equipment safer and more stable during the filling process.
