Description

Technical Field

[0001] The utility model relates to the technical field of intelligent instruments, in particular to an intelligent instrument which is easy to assemble and disassemble. Background Art

[0002] The original smart meters were called automatic meter reading systems (AMR), and remote automatic meter reading has become the most basic function of smart meters. By using the infrared and other communication functions of smart meters, automatic meter reading can be achieved, which eliminates the need for staff to go to the site for manual meter reading, improves efficiency, and reduces the cost of meter reading services. In addition, it can also reduce errors caused by human factors, improve meter reading accuracy, and increase profits. Later, the remote operation function of two-way communication was also added to prevent illegal use of electricity / gas, etc. Therefore, smart meters were initially used and favored by the energy industry.

[0003] When the front shell and the rear shell of the smart meter are combined, they are mostly fixed with bolts and keyholes. When the internal of the smart meter needs to be inspected, the front shell and the rear shell of the smart meter need to be disassembled. Therefore, when the front and rear shells of the smart meter are disassembled and assembled, designated tools are required for auxiliary operation, which brings inconvenience to the operator. Therefore, we propose a smart meter that is easy to disassemble and assemble. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an intelligent meter that is easy to disassemble and assemble, including a meter main shell 1, a mounting plate 2 is fixedly connected to the left side of the meter main shell 1, a mounting shell 3 is sleeved on the surface of the mounting plate 2, a display screen and a plurality of buttons are fixedly connected to the left side of the mounting shell 3, and the plurality of buttons are arranged below the display screen. The interior of the mounting shell 3 includes:

[0027] Positioning components 4, multiple positioning components 4 are respectively arranged at the upper and lower sides of the interior of the mounting shell 3, and the positioning components 4 include positioning blocks 41, the surface of the positioning blocks 41 is sleeved with positioning sleeves 42, the inner wall of the positioning sleeves 42 matches the surface of the positioning blocks 41, and the surface of the positioning blocks 41 is fixedly connected to the limiting blocks 43;

[0028] The clamping assembly 5 is arranged inside the positioning sleeve 42, and the clamping assembly 5 includes an elastic card 51, and the elastic card 51 is arranged in a U shape. A clamping block 52 is provided on the top of the elastic card 51, and the clamping block 52 is arranged in a triangle shape. A clamping groove 53 is provided on the right side of the positioning block 41, and the inner wall of the clamping groove 53 is arranged in the same shape as the clamping groove 53 and the clamping block 52.

[0029] The left end of the positioning block 41 is fixedly connected to the left side of the inner wall of the mounting shell 3 , the right side of the positioning sleeve 42 is fixedly connected to the left side of the mounting plate 2 , and one end of the elastic card 51 is fixedly connected to the left side of the mounting plate 2 .

[0030] An opening is provided on the right side of the mounting plate 2, and the plurality of openings are arranged on the right side of the positioning sleeve 42. A groove is provided on the lower side of the inner wall of the opening, and a reset component 6 is arranged inside the groove. The reset component 6 includes a top shell 61, and slide grooves are provided on the left and right sides of the inner wall of the groove. The inner walls of the two slide grooves are slidably connected to the left and right sides of the top shell 61 respectively through sliders, and a reset spring 62 is fixedly connected to the upper side of the inner wall of the top shell 61.

[0031] The lower end of the return spring 62 is fixedly connected to the lower side of the inner wall of the groove.

[0032] During use, when the mounting plate 2 and the mounting shell 3 are combined, the mounting shell 3 is sleeved on the mounting plate 2, and the plurality of positioning blocks 41 on the mounting shell 3 are inserted into the positioning sleeve 42 in the mounting plate 2, and the plurality of elastic cards 51 enter the card slots 53 in the positioning sleeve 42. When the elastic cards 51 are inserted into the card slots 53, the elastic cards 51 are compressed due to the shape of the card slots 53. At the same time, after the card blocks 52 on the elastic cards 51 enter the card slots 53, the card blocks 52 are clamped in the card slots 53 due to the rebound effect of the elastic cards 51.

[0033] When the elastic card 51 is compressed, the return spring 62 is compressed into the groove by the elastic card 51.
