Description

Technical Field

[0001] This utility model belongs to the technical field of refrigerant accessories and relates to a digital display of refrigerant pressure. Background Technology

[0002] Refrigerant pressure gauges are mainly used to measure the pressure values ​​of various refrigerants in different states within refrigeration systems or equipment, such as air conditioning equipment, cold storage refrigeration systems, industrial chillers, refrigerant filling equipment, and central air conditioning systems. Pressure gauges are typically connected via threaded pipe fittings, and their positions are usually fixed. However, in actual use, situations arise where the pipe fittings are not long enough, and moving the equipment is inconvenient, necessitating the replacement of the pressure gauge. This requires disassembling and reinstalling the pressure gauge, a relatively cumbersome process that fails to meet usage requirements. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an adjustable position digital pressure gauge.

[0004] The objective of this utility model can be achieved through the following technical solution: A refrigerant pressure digital display meter, comprising an assembly body with meter one and meter two, characterized in that a sliding groove is provided on the rear end face of meter one and meter two along their length direction, meter one is provided with a slide rail that slides and engages with it at the sliding groove, both ends of the slide rail extend axially outward and extend out of meter one, and one end of the slide rail extends axially to the sliding groove in meter two, and a mating unit is provided at the corresponding sliding groove of meter one and meter two and connected to it and engaging with the slide rail.

[0005] In the aforementioned refrigerant pressure digital display, the slide rail has folded edges on both sides that fit against the first and second displays, and several weight-reducing holes are provided on the end face of the slide rail along its length.

[0006] In the aforementioned refrigerant pressure digital display meter, the mating unit includes a pressure plate and two pressure blocks. The two pressure blocks are symmetrically arranged on corresponding gauges 1 and 2. The pressure blocks are located at the upper end of the slide groove. Gauges 1 and 2 are provided with mounting grooves for installing the pressure plate and communicating with the slide groove. The pressure plate has radially outward protrusions on both side walls that slide into the protrusions. The upper end of the pressure plate has several limiting parts that are connected to it and fit against the corresponding folded edges. The lower end of the pressure plate has a disassembly part that protrudes axially downward and facilitates the disassembly of the pressure plate. The end faces of gauges 1 and 2 have communicating grooves that facilitate the disassembly parts to extend out of gauges 1 and 2 and communicate with the mounting grooves.

[0007] Compared with existing technologies, this refrigerant pressure digital display gauge can be adjusted in position by setting a slide groove and a matching unit, thereby meeting the usage requirements of different distances. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the rear view of the digital refrigerant pressure display.

[0009] In the diagram, 1 is Table 1; 2 is Table 2; 3 is the slide rail; 4 is the folded edge; 5 is the pressure plate; 6 is the pressure block; and 7 is the disassembly part. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, this refrigerant pressure digital display includes an assembly body with a gauge 1 and a gauge 2. The rear end faces of gauges 1 and 2 each have a groove extending along their length and axially penetrating the corresponding gauge 1 and gauge 2. A slide rail 3 is provided at the groove of gauge 1, slidingly engaging with it. Both ends of the slide rail 3 extend axially outwards and out of gauge 1, with one end extending axially to the groove in gauge 2 and then axially extending out of the groove. Each gauge 1 and gauge 2 has a mating unit at its corresponding groove, connecting to and engaging with the slide rail 3. Both sides of the slide rail 3 have bent edges 4 that fit snugly against gauges 1 and 2. These edges 4 are L-shaped. Several weight-reducing holes are provided on the end face of the slide rail 3 along its length, allowing connection to other equipment. The mating unit includes a pressure plate 5 and two pressure blocks 6. The pressure blocks 6 are all set on the corresponding Table 1 and Table 2, and are arranged symmetrically. The pressure blocks 6 are located at the upper end of the slide groove. Table 1 and Table 2 are each provided with an installation groove for the installation of the pressure plate 5 and connected to the slide groove. The height of the installation groove is less than the height of the slide groove, and the installation groove is located below the pressure block 6. The two side walls of the pressure plate 5 are provided with radially outward protrusions that slide into the protrusions. The two inner side walls of Table 1 and Table 2 at the installation groove are provided with limiting grooves for the installation of the protrusions. The position of the pressure plate 5 is limited by the limiting grooves. The upper end of the pressure plate 5 is provided with several limiting parts that are connected to it and fit with the corresponding folded edge 4. The lower end of the pressure plate 5 is provided with a disassembly part 7 that protrudes axially downward and facilitates the disassembly of the pressure plate 5.
