Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an electricity meter that is easy to assemble. Background Technology

[0002] In the current field of electricity meter technology, the terminal design of electricity meters typically requires that the power cord be completely installed inside the meter to ensure the safety and stability of the electrical connection and to avoid the risk of electric shock or short circuit caused by exposed power cords. However, in actual installation, this design presents certain operational difficulties.

[0003] Specifically, power cords typically consist of internal copper conductors and an external insulation sheath. During installation, the insulation sheath must first be peeled back to expose the internal copper conductors before they are inserted into the terminals of the electricity meter. However, the process of peeling back the insulation is often difficult to control precisely. Peeling back too much insulation results in an excessively long exposed copper conductor, while peeling back too little prevents the conductor from being fully inserted into the terminal, causing poor contact. This operational inconvenience not only increases installation time but also affects the performance stability and safety of the electricity meter. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to provide an easy-to-assemble electricity meter, which solves the problems mentioned in the background above.

[0006] (II) Technical Solution

[0007] An easy-to-assemble electricity meter includes an electricity meter body. Multiple sets of connection terminals are provided at the bottom of the electricity meter body. Multiple sets of fastening bolts are movably installed on one outer surface of each set of connection terminals. Terminal holes are formed at the bottom of the multiple sets of connection terminals. Threads are formed on the inner wall of the terminal holes, and an adjusting tube is movably installed on the inner wall of the terminal holes. Threads are formed on both the upper and lower outer surfaces of the adjusting tube. A clamping ring is connected to the bottom of the adjusting tube. Multiple sets of vertical through grooves are formed on the outer surface of the clamping ring, and a compression ring is movably installed on the lower outer surface of the clamping ring.

[0008] Preferably, a limit ring is fixedly installed on the outer surface of the regulating tube.

[0009] Preferably, multiple handles are fixedly installed on the outer surfaces of both the limiting ring and the compression ring.

[0010] Preferably, the top of the compression ring is conical.

[0011] Preferably, the outer surface of the extrusion ring is wrapped with rubber.

[0012] Preferably, two sets of connecting posts are fixedly installed on both outer surfaces of the main body of the electricity meter, and a screw groove is opened on one side of each set of connecting posts.

[0013] Preferably, magnetic blocks are fixedly installed on one outer surface of the two sets of connecting columns.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. This utility model adjusts the height of the regulating tube by rotating the handle on the limiting ring, thus blocking excess copper wire. Subsequently, rotating the extrusion ring compresses the clamping ring, causing it to elastically deform and clamp the power cord, ensuring the integrity and safety of the entire assembly process and improving assembly efficiency.

[0016] 2. This utility model utilizes magnetic blocks to easily and initially attach the electricity meter body to the mounting bracket, achieving quick and accurate initial positioning. This design not only simplifies the installation process and improves efficiency but also ensures the stability and safety of the electricity meter body during installation. Subsequently, using the screw grooves on the connecting posts, screws can be easily inserted to securely install the electricity meter body in the designated position. This installation method is not only robust and reliable but also facilitates subsequent maintenance and replacement. Attached Figure Description

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] An easy-to-assemble electricity meter includes an electricity meter body 1. The bottom end of the electricity meter body 1 is provided with multiple sets of connection terminals 7. Multiple sets of fastening bolts 8 are movably installed on one side of the outer surface of the multiple sets of connection terminals 7. The bottom end of the multiple sets of connection terminals 7 is provided with terminal holes 9. The inner wall of the terminal holes 9 is threaded. An adjusting tube 5 is movably installed on the inner wall of the terminal holes 9. The upper and lower outer surfaces of the adjusting tube 5 are both threaded. The bottom end of the adjusting tube 5 is connected to a clamping ring 513. The outer surface of the clamping ring 513 is provided with multiple sets of vertical through grooves 514. A compression ring 6 is movably installed on the bottom outer surface of the clamping ring 513.

[0026] Furthermore, a limiting ring 511 is fixedly installed on the outer surface of the adjusting tube 5. The limiting ring 511 serves as a reference point for fixing and adjusting the adjusting tube 5, making it easier for the user to grasp and rotate the adjusting tube 5 to adjust its height. At the same time, the limiting ring 511 also plays a certain limiting role, preventing the adjusting tube 5 from moving excessively or falling off during rotation.

[0027] Furthermore, multiple handles 512 are fixedly installed on the outer surfaces of the limiting ring 511 and the compression ring 6. The design of the handles 512 makes it easier for users to grasp and rotate the limiting ring 511 and the compression ring 6, thereby improving the convenience and efficiency of operation.

[0028] Furthermore, the top of the compression ring 6 is conical. This conical design allows the compression ring 6 to more easily insert into and compress the clamping ring 513 during rotation, thereby achieving a clamping effect. In addition, the conical design also allows the compression ring 6 to gradually apply greater pressure during rotation, thus ensuring the firmness of the clamping.

[0029] Furthermore, the outer surface of the extrusion ring 6 is covered with rubber.

[0030] Furthermore, two sets of connecting posts 2 are fixedly installed on both outer surfaces of the main body 1 of the electricity meter, and each set of connecting posts 2 has a screw groove 3 on one side. The design of the connecting posts 2 and the screw groove 3 makes it easier for the main body 1 of the electricity meter to be connected to the mounting bracket or other fixing devices. By inserting screws through the screw groove 3 and tightening them, the firmness and stability of the main body 1 of the electricity meter can be ensured.

[0031] Furthermore, magnetic blocks 4 are fixedly installed on one outer surface of each of the two sets of connecting columns 2. The design of the magnetic blocks 4 makes it easier for the main body of the electricity meter 1 to be attracted to the mounting bracket during initial installation, achieving initial positioning. This not only improves the convenience of installation but also reduces errors and troubles during the installation process to a certain extent.

[0032] Working principle: During the installation of the electricity meter body 1, the magnetic properties of the magnetic block 4 are first used to initially attract the electricity meter body 1 to the mounting bracket, achieving initial positioning. Subsequently, screws can be easily inserted through the screw grooves 3 on the connecting post 2 to further securely install the electricity meter body 1 in the designated position.

[0033] Next is the power cord assembly process. Insert the copper wire portion of the power cord through the opening of terminal hole 9 until the required connection depth is reached. During this process, if the copper wire is too long, causing some to protrude from the outer surface of terminal hole 9, the vertical position of the adjusting tube 5 can be adjusted by rotating the handle 512 on the outer surface of the limiting ring 511. Since the upper surface of the adjusting tube 5 is threaded, it can match the threads on the inner wall of terminal hole 9, achieving precise height adjustment. By adjusting the position of the adjusting tube 5, excess copper wire can be effectively concealed, maintaining overall neatness and safety.

[0034] After adjusting the position of the regulating tube 5, the power cord needs to be clamped and secured. This is done by rotating the compression ring 6, which engages with the threaded surface of the lower end of the regulating tube 5, and then using its conical end to compress the clamping ring 513. Because the outer surface of the clamping ring 513 has multiple sets of vertical through grooves 514, it undergoes elastic deformation when compressed, thus contracting and clamping the power cord. This clamping method is not only simple and convenient but also effectively ensures the stability and reliability of the power cord.

[0035] Finally, by tightening the fastening bolt 8, the connecting terminal 7 can be securely connected to the power cord.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
