Therefore, an easier-to-install electricity meter has been designed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an easy-to-install electricity meter, aiming to solve to some extent the technical problems in the prior art where, due to space limitations within a standard distribution cabinet, the existing installation methods are cumbersome, inconvenient for electricity meter installation, and lack stability.

[0005] To achieve the above objectives, the technical solution adopted in this application is: an easy-to-install electricity meter, including an assembly plate, a guide rail fixedly connected to the front of the assembly plate, and an electricity meter detachably connected to the guide rail;

[0006] The electricity meter has mounting components snapped onto both sides, and a locking mechanism is connected to the mounting components. The mounting components and the locking mechanism work together to fix the electricity meter horizontally.

[0007] The locking mechanism is provided with an abutting end, which forms a pressing fit with the front of the guide rail.

[0008] In one feasible technical solution of this application, the electricity meter includes a body part, and the back of the body part is provided with a longitudinal fixing groove adapted to the guide rail.

[0009] In one feasible technical solution of this application, the back sides of the main body are symmetrically provided with insertion slots, and the insertion slots are connected to the fixing slots;

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] like Figures 1-3 As shown, an easy-to-install electricity meter includes an assembly plate 100, a guide rail 200 fixedly connected to the front of the assembly plate 100, and an electricity meter 300 detachably connected to the guide rail 200.

[0035] The electricity meter 300 has mounting parts 400 snapped onto both sides, and a locking mechanism 500 is connected to the mounting parts 400. The mounting parts 400 and the locking mechanism 500 cooperate to fix the electricity meter 300 horizontally.

[0036] The locking mechanism 500 has an abutment end that forms a pressing fit with the front of the guide rail 200. The electricity meter 300 is installed on the guide rail 200, and the mounting parts 400 are snapped into both sides of the electricity meter 300. The locking mechanism 500 fixes the electricity meter 300 in place, with the end of the locking mechanism 500 pressing tightly against the guide rail 200, making the electricity meter 300 securely installed.

[0037] like Figure 4 As shown, the electricity meter 300 includes a body part 301. The back of the body part 301 is provided with a longitudinal fixing groove 302 that is adapted to the guide rail 200, so as to facilitate the installation of the electricity meter 300 on the guide rail 200 and prevent the electricity meter 300 from tilting forward or backward after installation, and always keep it in an upright state.

[0038] like Figure 4 As shown, the back of the main body 301 is symmetrically provided with insertion slots 303 on both sides, which communicate with the fixing slots 302; the inner top wall and inner bottom wall of the insertion slots 303 are provided with multiple locking slots 304 at equal intervals. This facilitates the connection of the mounting component 400 to the electricity meter 300. The locking slots 304 can engage the locking blocks 403 on the mounting component 400, thus firmly fixing the mounting component 400 to the electricity meter 300. The design of multiple locking slots 304 allows for selection of different installation positions as needed, providing greater flexibility and convenience.

[0039] like Figure 5 As shown, the mounting component 400 includes a mounting plate 401, with symmetrical support plates 402 at its upper and lower inner sides. The support plates 402 have locking blocks 403 at their ends that fit into the slots 304. The mounting plate 401 has threaded holes 404 on its front side, with the axis of the threaded holes 404 perpendicular to the front side of the guide rail 200. Inserting the mounting plate 401 into the insertion slot 303 and pushing it allows the locking blocks 403 to engage in the slots 304, thus fixing the mounting component 400 onto the electricity meter 300. The threaded holes 404 on the mounting plate 401 are used to install a locking mechanism 500. The locking mechanism 500 passes through the threaded holes 404 and can be vertically pressed against the guide rail 200, thereby fixing the electricity meter 300 in place.

[0040] like Figure 1 As shown, the locking mechanism 500 includes a locking bolt, the shank of which passes through a threaded hole 404; the end of the locking bolt is provided with an elastic pressure head, which is made of rubber and abuts against the front of the guide rail 200. The locking bolt passes through the threaded hole 404 on the mounting plate 401, and rotating the locking bolt can adjust the position of the end elastic pressure head, so that the elastic pressure head presses tightly against the guide rail 200.

[0041] like Figure 5As shown, the mounting component 400 also includes two positioning rods 405, which are vertically connected to the opposing surfaces of the two support plates 402. Compression springs 406 are sleeved around the outer periphery of the positioning rods 405, providing support and guidance for the compression springs 406. The two ends of the compression springs 406 abut against the inner sides of the two support plates 402, respectively. The elastic force of the compression springs 406 causes the locking block 403 to be more tightly engaged in the locking groove 304, preventing the locking block 403 from falling out of the locking groove 304, thus making the connection between the mounting component 400 and the electricity meter 300 more secure and reliable.

[0042] like Figure 5 As shown, pull plates 407 are fixedly connected to the inner sides of both support plates 402. The side of the pull plate 407 is provided with a through groove. After the energy meter 300 is removed from the guide rail 200, the pull plate 407 is pulled inward to make the locking block 403 engage with the locking groove 304, which makes it easy to remove the mounting component 400 from the energy meter 300.

[0043] When in use, insert the mounting plate 401 into the insertion slot 303, push the mounting plate 401, and the locking block 403 can be locked into the locking slot 304 to fix the mounting component 400 on the energy meter 300.

[0044] Then the electricity meter 300 is installed on the guide rail 200. The guide rail 200 is snapped into the longitudinal fixing groove 302 on the back of the main body 301 to prevent the electricity meter 300 from tilting forward or backward after installation and to keep it upright at all times.

[0045] Pass the locking bolt through the threaded hole 404 on the mounting plate 401, rotate the locking bolt to make the elastic pressure head press firmly on the guide rail 200, and complete the quick installation of the electricity meter 300.

[0046] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
