[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1: Figure 1-Figure 4 As shown, the utility model provides an electronic meter head with electromechanical separation and instant replacement, including a watch case 1 and a watch cover 4. A chip slot 11 is provided at the top of the watch case 1 near the front edge, and slots 12 are symmetrically provided at the inner bottom of the chip slot 11 near the two side edges. A plurality of pressing edges 43 are fixedly connected between the inner surface walls of the watch cover 4 near the bottom, wherein the bottoms of two pressing edges 43 are fixedly connected with a clamping block 44. A digital display chip 5 is placed inside the chip slot 11, and the bottom of the pressing edge 43 and the digital display chip 5 are fixedly connected. The tops are fitted together, the card block 44 and the slot 12 are matched, and the top of the case 1 is provided with an embedded groove 2 near the four corners of the chip slot 11, and the inner wall of the embedded groove 2 is symmetrically provided with a limiting groove 21 near the inner bottom, and a top column 23 is slidably arranged between the inner walls of the embedded groove 2, and the outer surface of the top column 23 is symmetrically fixedly connected with a limiting block 24 near the bottom, and the limiting block 24 and the limiting groove 21 are slidably matched, and a spring 22 is connected between the inner top of the top column 23 and the inner bottom of the embedded groove 2.

[0023] The effect achieved by the entire embodiment 1 is that when in use, the digital display chip 5 is placed inside the chip slot 11 after the circuit connection is completed, and then the cover 4 is buckled and pressed. At this time, the pressing edge 43 of the inner wall of the cover 4 will press the digital display chip 5 tightly, and at the same time, the top column 23 will be squeezed and retracted into the inside of the embedded slot 2 and squeeze the spring 22 to contract. The block 44 will be squeezed inside the chip slot 11 and slightly bend inward. When the end of the block 44 passes through the slot 12, the whole loses the squeezing force and will recover and engage, thereby completing the installation of the cover 4 and the digital display chip 5. When removing, After squeezing the exposed bottom parts of the two clamping blocks 44, the meter cover 4 loses its fixation. At this time, the spring 22 rebounds and generates thrust to push the top column 23 upward. At this time, the top column 23 will lift the meter cover 4 upward, and the meter cover 4 can be easily pulled off upward, and then the digital display chip 5 can be taken out for repair and replacement. The whole does not require the use of extra tools and is convenient for disassembly and assembly, thereby reducing maintenance time and cost, improving maintenance efficiency, and ensuring the normal operation of the water meter. The height of the limit groove 21 is less than the height of the embedded groove 2, and the limit block 24 is mainly used to limit the top column 23.

[0024] Example 2: Figure 1-Figure 4 As shown, the outer surface of the watch case 1 is fixedly connected with a plurality of positioning blocks 3, the outer surface of the watch cover 4 is fixedly connected with a plurality of connecting blocks 41, the positions of the connecting blocks 41 and the positioning blocks 3 correspond, the bottom of the connecting blocks 41 is fixedly connected with a positioning column 42, the outer surfaces of the connecting blocks 41 and the positioning blocks 3 are fitted together, and the bottom end of the positioning column 42 slides through the outer surface of the positioning block 3.

[0025] The effect achieved by the entire embodiment 2 is that during the installation of the watch cover 4, the connecting blocks 41 around its surface will be close to the positioning blocks 3 around the surface of the watch case 1. As the watch cover 4 is installed, the positioning columns 42 at the bottom of the connecting blocks 41 will be synchronously inserted into the holes on the surface of the positioning blocks 3, thereby playing a positioning role, avoiding the deviation of the watch cover 4, improving the stability and protection effect of the watch cover 4, and having a simple structure and high practicality.

[0026] Working principle: When in use, after the circuit connection of the digital display chip 5 is completed, it is placed inside the chip slot 11, and then the cover 4 is buckled and pressed. At this time, the edge 43 of the inner wall of the cover 4 will press the digital display chip 5 tightly, and at the same time, the top column 23 will be squeezed and retracted into the inside of the embedded slot 2 and squeeze the spring 22 to contract. The block 44 will be squeezed inside the chip slot 11 and slightly bent inward. When the end of the block 44 passes through the slot 12, the whole loses the squeezing force and will recover and engage, thereby completing the installation of the cover 4 and the digital display chip 5. When removing, the exposed parts at the bottom of the two blocks 44 are squeezed to make the cover 4 lose its fixation. At this time, the spring 22 rebounds and generates thrust to push the top column 2 upward. 3. At this time, the top column 23 will push the meter cover 4 upward, and the meter cover 4 can be easily pulled up and then the digital display chip 5 can be taken out for maintenance and replacement. No extra tools are required and the disassembly and assembly are convenient, thereby reducing maintenance time and cost, improving maintenance efficiency, and ensuring the normal operation of the water meter. In addition, during the installation of the meter cover 4, the connecting blocks 41 around its surface will be close to the positioning blocks 3 around the surface of the case 1. As the meter cover 4 is installed, the positioning columns 42 at the bottom of the connecting blocks 41 will be synchronously inserted into the holes on the surface of the positioning blocks 3, thereby playing a positioning role, avoiding the displacement of the meter cover 4, improving the stability and protection effect of the meter cover 4, and having a simple structure and high practicality.
