[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, Figure 1 The figure shows the cooperation between the base of the gas meter counter and the counter body in the embodiment (top view). Figure 2 The figure shows the schematic diagram of the counter body in the embodiment. Figure 1 (Top-down perspective); Figure 3 The figure shows the schematic diagram of the counter body in the embodiment. Figure 2 (side view); Figure 4 Shown is Figure 1 Schematic diagram of the enlarged structure at A in the middle; Figure 5 Shown is Figure 1 Schematic diagram of the middle cover Figure 1 (Top-down perspective);

[0026] The device includes:

[0027] U-shaped base 11;

[0028] The counter body is detachably embedded in the base 11 and includes a connecting plate 1 and a counter 2. L-shaped fixing blocks 21 are provided at the four corners of the connecting plate 1. A slot 23 is provided on the base 11 corresponding to each fixing block 21. The slot 23 matches the shape of the corresponding fixing block 21, and the fixing block 21 is movably embedded in the slot 23.

[0029] The cover plate 12 is detachably mounted on the open end of the base 11 , and is provided with a window 13 .

[0030] By embedding the fixing block 21 of the counter body into the slot 23 of the base 11, the counter body and the base 11 can be quickly disassembled and assembled, and the installation position is accurate; the cover plate 12 detachably installed on the open end of the base 11 can abut the counter body to ensure the stability of the installation of the counter body. The detachable clip-on installation method makes it possible to disassemble the counter without the use of special tools, simplifies the installation process, and improves the efficiency of disassembly and assembly.

[0031] The U-shaped base 11 is provided with a clearance hole that matches other structures of the gas meter to ensure that the counter body can match the relevant structure in the existing technology and realize the counting function based on the Hall effect.

[0032] like Figure 1 、 Figure 5 、 Figure 6 As shown, Figure 1 The figure shows a schematic diagram of the cooperation between the base of the gas meter counter and the counter body in the embodiment (top view); Figure 5 Shown is Figure 1 Schematic diagram of the middle cover Figure 1 (Top view), Figure 6 Shown is Figure 1 Schematic cross-sectional view of the middle cover (side view);

[0033] The base 11 is also vertically provided with a plurality of fixing columns, each of which is provided with a mounting hole 111 . The cover 12 is provided with an insertion column 121 at one end close to the base 11 and corresponding to the mounting hole 111 . The insertion column 121 is plugged into the mounting hole 111 .

[0034] The plug post 121 and the mounting hole 111 are both cylindrical in shape, and their diameters match to ensure that the plug post 121 can be smoothly and stably inserted into the mounting hole 111. The cover plate 12 is installed on the U-shaped base 11 by plugging, which also makes disassembly and assembly convenient.

[0035] like Figure 1 、 Figure 4 As shown, Figure 1 The figure shows the cooperation between the base of the gas meter counter and the counter body in the embodiment (top view). Figure 4 Shown is Figure 1 Schematic diagram of the enlarged structure at A in the middle;

[0036] Two positioning posts 22 are horizontally provided on the base 11 at the position corresponding to each fixed block 21. There is a gap between the two positioning posts 22 to form a slot 23. A slide 31 is also slidably provided on the two positioning posts 22. When the slide 31 slides to the top of the fixed block 21, the fixed block 21 is pressed into the slot 23. When the slide 31 slides to a position away from the fixed block 21, it does not affect the fixed block 21 from entering the slot 23.

[0037] A sliding groove 32 is formed on each of the two positioning posts 22 of each group, and a slider that slides in cooperation with the sliding groove 32 is provided on the slide plate 31 .

[0038] The slide 31 can press the fixed block 21 by changing its position, and the cover 12 resists the slide 31, so that the counter body is installed stably. When disassembling, after removing the cover 12, slide the slide 31 to the end away from the fixed block 21 until the fixed block 21 can be smoothly disengaged from the slide groove 32.

[0039] like Figure 1 、 Figure 2 As shown, Figure 1The figure shows the cooperation between the base of the gas meter counter and the counter body in the embodiment (top view). Figure 2 The figure shows the schematic diagram of the counter body in the embodiment. Figure 1 (Top-down perspective);

[0040] The base 11 is further provided with a plurality of first card blocks 41 , and the connecting plate 1 of the counter body is provided with second card blocks 42 at positions corresponding to the first card blocks 41 , and the second card blocks 42 are engaged with the first card blocks 41 .

[0041] The first clamping block 41 and the second clamping block 42 are provided to provide a plurality of clamping points, so as to improve the installation stability of the counter body.

[0042] Working principle: When assembling the counter body of this device with the base 11, the fixing block 21 on the connecting plate 1 is embedded in the slot 23 formed by the positioning column 22 of the base 11, and the second clamping block 42 is engaged with the first clamping block 41. Then, the slide 31 on the positioning column 22 is slid to the top of the fixing block 21 and the cover 12 is installed on the open end of the U-shaped base 11 by plugging, so as to realize the rapid assembly of the counter body and the base 11.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
