[0035] Please refer to Figures 1-7 , the utility model discloses a guide rail type electric energy meter shell convenient to connect will be described, the utility model discloses a total of 4 parts are formed, as shown in Figure 1 、 Figure 2 , including shell 1, flip door 3, electricity connection block 4 and telescopic assembly, the inside of shell 1 is hollow structure, the front side wall of shell 1 is provided with electricity connection port 2, flip door 3 is hinged on the front side wall of shell 1, flip door 3 can close electricity connection port 2, electricity connection block 4 is slidably connected in the inside of electricity connection port 2, and telescopic assembly is arranged between flip door 3 and electricity connection block 4.

[0036] In the embodiment, the inside of shell 1 is provided with electric energy meter body, the central part of the front side wall of shell 1 is provided with liquid crystal display panel that can display the real-time data of electric energy meter body, the upper and lower sides of the front side wall of shell 1 are provided with flip door 3, as openable protective cover, to protect internal wiring terminal. This openable flip door 3 is to facilitate the opening of internal electrical wiring by later maintenance personnel, and a groove for opening flip door 3 is also arranged on the side.

[0037] By setting flip door 3, the electricity connection block 4 in the inside of shell 1 can be effectively protected from dust, water vapor erosion and accidental touch in the closed state, and the safety of electricity use is ensured, and when opening, a convenient operation channel is provided for maintenance personnel, greatly simplifying the maintenance and maintenance process of internal electrical wiring.

[0038] By setting electricity connection block 4 and telescopic assembly, when opening flip door 3, electricity connection block 4 can automatically extend a certain distance from inside to outside of electricity connection port 2, so that the wiring operation position is closer to the installer, effectively solving the problem that the arm is difficult to extend into the deep part for wiring in the narrow installation space, greatly reducing the installation difficulty and improving the installation efficiency.

[0039] As shown in Figure 2 、 Figure 3 、 Figure 4 , two through grooves 21 are formed on the inner wall of electricity connection port 2, two electricity connection holes 41 are formed on the top wall of electricity connection block 4, two wires 42 are arranged on the rear side wall of electricity connection block 4, the wires 42 are electrically connected with the electricity connection holes 41, two threaded holes 43 are formed on the front side wall of electricity connection block 4, and the threaded holes 43 are in internal communication with the electricity connection holes 41.

[0040] In the embodiment, the two power connection holes 41 on each power connection block 4 are connected with the zero line and the live line respectively. Since the position of connecting the external power line is on the top of the power connection block 4, a through slot 21 is needed to be opened on the inner wall of the power connection port 2, through which the external power line enters the inside of the shell 1 when the flip cover door 3 is closed. A wire guide 42 is arranged on the back wall of the power connection block 4, one end of which is electrically connected with the power connection hole 41, and the other end of which is electrically connected with the power meter body. The threaded hole 43 is a structure commonly used in the prior art for fixing the power line, which is also arranged on the power connection block 4 and moves with the power connection block 4, so that the connection process is more convenient and reliable.

[0041] As shown in Figure 2 , Figure 3 , Figure 6 , the opposite two side walls of the power connection block 4 are provided with sliding blocks 44, and the opposite two inner side walls of the power connection port 2 are provided with sliding grooves 22, and the power connection block 4 is slidably connected in the power connection port 2 through the sliding grooves 22.

[0042] In the embodiment, as can be seen from the drawings, the top surface of the power connection block 4 is lower than the top surface of the shell 1. This has the advantages that the operation space on the upper part of the power connection port 2 is increased, the movement range of the installer's hand is increased, the installer can easily install in a narrow space, and the power connection block 4 will protrude forward by a part. Although the protruding range does not seem to be large, for a narrow or deep installation space, the protruding part makes the installer's arm not need to reach again, which greatly reduces the difficulty of installation.

[0043] The arrangement positions of the sliding blocks 44 and the sliding grooves 22 are shown in Figure 2 , Figure 3 , the sliding blocks 44 are arranged in four, two as a group, which ensures that the sliding direction of the power connection block 4 is more stable.

[0044] As shown in Figure 3 , Figure 4 , the telescopic assembly includes a rotating shaft seat 51, a shaft hole 52 and a push-pull rod 53. The rotating shaft seat 51 is arranged in pairs and fixedly connected to the inner side wall of the flip cover door 3. The shaft hole 52 is arranged in pairs and opened on the side wall of the power connection block 4. The push-pull rod 53 is arranged in pairs, one end of which is rotatably connected in the rotating shaft seat 51, and the other end of which is rotatably connected in the shaft hole 52.

[0045] In the embodiment, the power connection block 4 can be automatically taken out by only opening the flip cover door 3, and the power connection block 4 can be automatically pushed back by closing the flip cover door 3. By arranging the rotating shaft seat 51, the shaft hole 52 and the push-pull rod 53, the opening / closing of the flip cover door 3 and the protruding / retracting of the power connection block 4 are linked, which is simple and reliable, does not need additional operation steps, and is convenient to use.

[0046] As Figure 5 , Figure 6 shown, the inner wall of the chute 22 is provided with an elastic sheet 221, and the outer side wall of the sliding block 44 is rounded.

[0047] In the embodiment, the setting position of the elastic sheet 221 is shown in Figure 6 The elastic sheet 221 is arranged on the inner wall of the chute 22 and between the two sliding blocks 44 on the same side. When the flip door 3 is opened, the sliding block 44 will be in contact with the elastic sheet 221, which will block the opening of the flip door 3. This setting is to prevent accidental touch. When the flip door 3 is continuously opened, the sliding block 44 will compress the elastic sheet 221. After the sliding block 44 passes, the elastic sheet 221 will restore the deformation and push the sliding block 44 to a certain extent, so that the user can feel the opening feedback. Preferably, the elastic sheet 221 is a metal sheet. The rounded corner of the outer side wall of the sliding block 44 can cooperate with the elastic sheet 221 to ensure the smooth and stable sliding process of the sliding block 44, improve the durability and operation feel of the product.

[0048] By arranging the elastic sheet 221, the blocking force can be provided at the initial stage of opening the flip door 3 to prevent accidental touch and enhance safety. When the sliding block 44 slides, the elastic sheet 221 can provide clear tactile feedback through its deformation and reset, and improve the operation feel.

[0049] As Figure 7 shown, the rear side wall of the shell 1 is formed with a guide rail groove 11. The present application significantly improves the installation convenience without changing the standard guide rail groove 11 structure at the rear of the shell 1, and is fully compatible with the existing guide rail installation system, which is convenient for promotion and application.

[0050] Although the utility model has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art.
