Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In this embodiment, a metering cabinet for convenient replacement of metering instruments comprises a metering cabinet body 1 and a metering instrument body 16 clamped inside the metering cabinet body 1, a support plate 10 is fixedly connected to the middle of the inner side of the metering cabinet body 1, a first wire hole 4 is provided on the upper end surface of the metering cabinet body 1, and second wire holes 11 are provided on both the left and right ends of the support plate 10, and a fixing assembly for clamping and fixing the metering instrument body 16 is provided on the inner bottom wall of the metering cabinet body 1 and the upper side of the support plate 10. The fixing assembly comprises a fixing frame 8 fixedly connected to the inner bottom wall of the metering cabinet body 1 and the upper side surface of the support plate 10, respectively, a positioning frame 12 is slidably connected inside the fixing frame 8, the inner bottom wall of the positioning frame 12 is fitted with the metering instrument body 16, two clamping rods 18 are sleeved inside the upper side of the positioning frame 12, and a first spring 15 is fixedly sleeved on the outer wall of the lower side of the clamping rod 18, and a first rotating shaft 19 is rotatably connected to the left and right ends of the lower side of the fixing frame 8, and a connecting rod 9 is rotatably sleeved inside the first rotating shaft 19.

[0024] Among them, an absorption component for absorbing dust inside the metering cabinet body 1 is arranged on the left side of the metering cabinet body 1, and the absorption component includes a filter box 5 connected to the left side of the metering cabinet body 1, and a filter plate 6 is slidably connected to the inner side of the filter box 5, and a vacuum cleaner 7 is fixedly installed on the side of the filter plate 6 away from the metering cabinet body 1, and a metering cabinet door 2 is hinged on the front end face of the metering cabinet body 1, and a glass window 3 is inlaid on the front end face of the metering cabinet door 2. Two third line holes are provided on the upper sides of the two fixed frames 8, and the two third line holes are arranged equidistantly laterally. The inner walls of the two fixed frames 8 are fixedly connected with guide blocks 13, and the left and right sides of the positioning frame 12 are fixedly connected with sliders 14, and the sliders 14 are slidably connected on the surface of the guide blocks 13. The connecting rod 9 is fixedly connected with a second spring 17 on the side close to the inner wall of the metering cabinet body 1, and the number of the second springs 17 is two, and the two second springs 17 are arranged equidistantly laterally.

[0025] It should be noted that the vacuum cleaner 7 will use the filter plate 6 to filter while sucking in the filter box 5 from the metering cabinet body 1, and the filter plate 6 can be removed from the vacuum cleaner 7 and clean the dust adsorbed on the surface. Normally, the line can be connected and fixed to the metering instrument body 16 through the first line hole 4 and the third line hole opened on the upper side of the fixing frame 8, and the lower side fixing frame 8 only needs to be connected from the second line hole 11.

[0026] The working principle of the above embodiment is:

[0027] The measuring instrument body 16 is placed in the positioning frame 12, and the clamping rods 18 at the front and rear ends of the upper side of the positioning frame 12 are pulled upward. As the measuring instrument body 16 is placed between the two clamping rods 18, the first spring 15 rebounds to make the lower surface of the clamping rod 18 contact with the front and rear ends of the measuring instrument body 16 and clamp it in the positioning frame 12. The sliders 14 on both sides of the positioning frame 12 are aligned with the surface of the guide block 13 and slid into the fixing frame 8 to be clamped. The rear side of the positioning frame 12 will contact with the surface of one end of the connecting rod 9. The line is inserted into the metering cabinet body 1 from the first line hole 4 and the third line hole opened on the upper side of the fixing frame 8. It is inserted into the interior and connected to the measuring instrument body 16, and the lower end fixing frame 8 can be moved to the lower side fixing frame 8 through the second line hole 11 opened on the support plate 10 to connect with the measuring instrument. The main body 16 is connected. You only need to close the metering cabinet door 2 to directly check the condition of the metering instrument main body 16 through the glass window 3. The suction force generated by the operation of the vacuum cleaner 7 on the surface of the filter box 5 absorbs the dust inside the metering cabinet main body 1 and discharges it into the filter box 5. During this period, the dust is adsorbed and filtered by the filter plate 6. It is necessary to regularly move the filter plate 6 from the upper side of the filter box 5 to clean the adsorbed dust. When the metering instrument main body 16 needs to be replaced and repaired, press the connecting rod 9 on the left and right sides of the fixing frame 8 under the action of the first rotating shaft 19 to drive the other end of the connecting rod 9 to tilt and push out the positioning frame 12. Pull the card rod 18 again to move the metering instrument main body 16 out. During this period, the line needs to be separated before it can continue to be moved out. The connecting rod 9 rebounds under the elasticity of the second spring 17 to move the connecting rod 9 to its original position.

[0028] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
