Description

Technical Field

[0001] The utility model relates to the technical field of refrigerant analyzers, and particularly relates to a housing of a refrigerant analyzer. Background Art

[0002] A refrigerant analyzer, also known as a refrigerant detector, mainly functions to detect gas leakage in a refrigerant system, and then mainly detects the composition and quality of the refrigerant by sampling samples.

[0003] To meet the principle of sampling detection, a sampling bottle slot is generally opened on the housing of the refrigerant analyzer for placing a sampling bottle. Usually, only a groove for embedding the bottle body is provided in the sampling bottle slot, so that the sampling bottle is only placed in the sampling bottle slot by embedding. Therefore, when the housing of the refrigerant analyzer is placed or moved in a box, the sampling bottle is extremely likely to be squeezed because the box containing the housing is squeezed or collided, resulting in a high probability of damage to the sampling bottle, affecting subsequent sampling use and reducing the analysis efficiency of the analyzer. Summary of the Utility Model

Detailed Embodiment

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a refrigerant analyzer housing as shown in Figures 1-4 , including a housing main body 100 and a sampling bottle slot 200 opened at the top of the housing main body 100. A limiting structure 300 is provided above the sampling bottle slot 200 and at the top of the housing main body 100. The limiting structure 300 includes a first limiting plate 301 and a second limiting plate 302. The first limiting plate 301 is fixedly arranged above the sampling bottle slot 200 and at the top of the housing main body 100. The first limiting plate 301 is used to limit the position of the sampling bottle in the sampling bottle slot 200. The second limiting plate 302 is movably arranged on both sides of the first limiting plate 301. An activity member for the movement of the second limiting plate 302 is arranged between the second limiting plate 302 and the first limiting plate 301.

[0022] Specifically referring to Figure 1 and Figure 2 , the housing main body 100 is the housing of the refrigerant analyzer. The main function of the refrigerant analyzer is to detect the gas leakage in the refrigerant system. The refrigerant analyzer is a prior art, and the specific structural principle will not be elaborated in detail in this embodiment. The housing main body 100 is adapted to the use of the refrigerant analyzer. A sampling bottle slot 200 for placing the sampling bottle is opened on the housing main body 100. The sampling bottle is usually embedded inside the sampling bottle slot 200. However, during the process of moving and transporting, although the refrigerant analyzer is loaded in the box, the sampling bottle is also likely to fall out of the sampling bottle slot 200. Therefore, a first limiting plate 301 is provided above the sampling bottle slot 200 to limit the top of the sampling bottle slot 200, so that the sampling bottle is not easily dropped out of the sampling bottle slot 200. At the same time, with the setting of the second limiting plate 302, the limiting range of the sampling bottle slot 200 can be adjusted, so as to better meet different limiting requirements. The number of the second limiting plates 302 is at least two, which are respectively located on both sides of the first limiting plate 301. Thus, with the cooperation of the activity member, the second limiting plates 302 can move synchronously and in the same direction, so as to adjust the limiting range, which helps to strengthen the diversity and flexibility of the sampling bottle limiting, and further strengthens the stability and safety of the sampling bottle placement.

[0023] The movable part includes a movable groove 304 and a movable rod 303. The movable groove 304 is formed on the side surface of the first limiting plate 301. The movable rod 303 is movably inserted into the inner cavity of the movable groove 304 and its end is connected to the second limiting plate 302. A rubber sleeve is fixedly sleeved on the outer wall of the movable rod 303.

[0024] Specific reference Figure 2 , while the movable rod 303 is movably inserted into the inner cavity of the movable groove 304 through the rubber sleeve, the friction between the rubber sleeve and the inner wall of the movable groove 304 can be utilized to keep the position of the movable rod 303 stable without external force, so that the second limiting plate 302 can move its position through the movement of the movable rod 303 along the inner cavity of the movable groove 304. At the same time, without external force, the moved second limiting plate 302 can also maintain the position limitation, thereby ensuring the limitation of the position of the sampling bottle in the sampling bottle groove 200. And the first limiting plate 301 is located in the middle above the sampling bottle groove 200, playing a main limiting role. In cooperation with the lateral movement of the second limiting plate 302, the limiting range can be adjusted according to the length of the sampling bottle, effectively enhancing the effectiveness of the sampling bottle limiting.

[0025] Connectors are arranged between the ends of the movable rod 303 and the second limiting plate 302. The connectors include a connecting rod 305 and a connecting groove 306. The connecting groove 306 is formed on the end face of the second limiting plate 302 facing the first limiting plate 301. The connecting rod 305 is fixedly inserted into the inner cavity of the connecting groove 306. External threads are formed on the outer wall of the connecting rod 305, and internal threads are formed on the inner wall of the connecting groove 306. The connecting rod 305 is threadedly connected with the inner cavity of the connecting groove 306.

[0026] Specific reference Figure 2 , the connecting rod 305 is fixedly arranged at the end of the movable rod 303. Through the connection with the connecting groove 306, the movable rod 303 can be relatively fixed to the second limiting plate 302, so that the second limiting plate 302 can move synchronously. At the same time, the threaded connection between the connecting rod 305 and the connecting groove 306 also makes the structure between the movable rod 303 and the second limiting plate 302 detachable, facilitating the flexible selection of the use of the second limiting plate 302 and providing convenience for the disassembly and assembly of the second limiting plate 302.

[0027] Two grooves are formed at the top end of the housing main body 100. A fixing structure 400 is arranged between the housing main body 100 and the first limiting plate 301. The fixing structure 400 includes two fixing rods 401 and two fixing sleeves 402. The two fixing sleeves 402 are respectively fixedly sleeved on the outer walls of the two fixing rods 401. The two fixing rods 401 are symmetrically and fixedly arranged at the bottom end of the first limiting plate 301. The two fixing rods 401 are respectively inserted into the inner cavities of the two grooves.

[0028] Specific referenceFigure 1 and Figure 3 , the fixing sleeve 402 is any one of elastic rubber or elastic silica gel. The setting of the fixing sleeve 402 helps to increase the friction between the fixing rod 401 and the inner wall of the groove. Therefore, after the fixing rod 401 is inserted into the corresponding groove, the connection can be fixed by the frictional resistance between the fixing sleeve 402 and the groove. Furthermore, the first limiting plate 301 is installed at the top of the housing main body 100 from top to bottom. Therefore, the method of directly inserting the fixing rod 401 into the inner cavity of the groove is simple and convenient. At the same time, during the movement of the refrigerant analyzer, with the setting of the box body, it can also be easily separated in the vertical or other states, ensuring the effectiveness of the use of the first limiting plate 301, and thus effectively improving the convenience and efficiency of the disassembly and assembly of the first limiting plate 301.

[0029] A pressing structure 500 is fixedly arranged at the bottom end of the first limiting plate 301. The pressing structure 500 includes a pressing arc plate 501, a telescopic rod 502, and a spring 503. The telescopic rod 502 is fixedly arranged between the pressing arc plate 501 and the first limiting plate 301, and the spring 503 is fixedly arranged in the inner cavity of the telescopic rod 502.

[0030] Specifically refer to Figure 4 , through the connection of the telescopic rod 502, the pressing arc plate 501 disassembles and installs the position along with the first limiting plate 301. After the first limiting plate 301 is installed at the top of the sampling bottle groove 200, the pressing arc plate 501 can press the sampling bottle, so that the space between the first limiting plate 301 and the sampling bottle has support. The telescopic rod 502 has telescopic performance through the spring 503 installed on the inner wall, so that the distance between the pressing arc plate 501 and the first limiting plate 301 can be automatically adjusted. At the same time, when the housing main body 1 and the first limiting plate 301 are collided, the telescopic rod 502 can use the spring 503 structure to buffer the collision force, strengthening the stability of the sampling bottle position while reducing the stress level of the sampling bottle.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
