Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electricity metering boxes, specifically relating to a three-phase multi-position electricity metering box. Background Technology
[0002] An electricity metering box is a device used in power systems to install electricity meters and related accessories. Its main function is to accurately measure the electricity consumption of users, ensuring that power companies can charge electricity fees based on actual consumption, while also protecting the legitimate rights and interests of electricity users.
[0003] Problems with existing technology:
[0004] Currently, in the process of using existing electricity metering boxes, the incoming line end usually does not have a fixed structure, which makes it easy for people to pull the cable, resulting in unauthorized connections and haphazard pulling, thus affecting the accuracy of the electricity metering box data. At the same time, due to the lack of a fixed structure, the cable is also prone to detachment from the three-phase electricity meter due to external pulling. Utility Model Content
[0005] The purpose of this utility model is to provide a three-phase multi-position electricity metering box, which can drive the anti-theft electricity mechanism to move by pushing the pressure plate with the screw, so that the pressure member drives the expansion fixing component to fix the cable through the pressure ring, and further fix it by rotating the fixing component, so as to avoid unauthorized connection and haphazard pulling of the cable under human action.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A three-phase multi-meter energy metering box includes a box body, a box door on the front of the box body, a three-phase energy meter fixedly installed inside the box body by a mounting bracket, and a fixing column fixedly installed inside the box body.
[0008] The screw installed on the internal thread of the fixed column is used to push the pressure plate to move linearly, so that the pressure plate drives the anti-pull mechanism to move synchronously.
[0009] The anti-pull mechanism includes a rotating fixing component rotatably mounted on the top of the pressure member. The pressure plate pushes the pressure member to cause the pressure ring to abut against the expansion fixing component, so that the expansion fixing component abuts against the cable.
[0010] The box is equipped with a partition to separate the metering chamber and the wire threading chamber, and the box door is hinged to the box.
[0011] The rotating fixing assembly includes a rotating cylinder, an adjusting ring is vertically slidably mounted on the outside of the rotating cylinder, an elastic band is fixedly connected between the rotating cylinder and the fixing ring, and the fixing ring is fixedly installed to the housing.
[0012] A spring is abutting between the adjusting ring and the rotating cylinder. The spring is used to push the adjusting ring to drive the positioning rod to move vertically, so that the positioning rod is inserted into the pressure piece.
[0013] The adjusting ring drives one end of the elastic band to rotate via the rotating cylinder, causing the elastic band to spirally wrap around the surface of the cable.
[0014] The expansion fixing assembly includes a connecting cylinder, and a spring is fixedly installed inside the connecting cylinder. The connecting cylinder is slidably installed with the pressure member through a limiting rod.
[0015] The pressure member abuts against the pressure plate, and the pressure plate pushes the pressure ring to move through the pressure member, so that the pressure ring pushes the spring to abut against the cable.
[0016] The technical effects achieved by this utility model are as follows:
[0017] This utility model utilizes a fixing post installed inside the housing. The screw threaded inside the fixing post can push the pressure plate to drive the pressure member and pressure ring to move linearly. This causes the pressure ring to push the spring inside the connecting cylinder to move inward, thereby clamping the inner wall of the spring with the cable. Since multiple expansion fixing components are provided and located between multiple pressure members, the cable can be fixed by the action of multiple expansion fixing components, avoiding external force pulling the cable.
[0018] This invention utilizes an adjusting ring located outside a rotating cylinder, with a spring between the adjusting ring and the rotating cylinder. By pushing the adjusting ring upwards and rotating it, the rotating cylinder can be driven to rotate, causing one end of the elastic band to rotate. Since the other end of the elastic band is fixed by a fixing ring, the elastic band can be spirally wound around the surface of the cable, further improving the cable's fixing effect and preventing unauthorized or haphazard connections.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0028] like Figure 1-6 As shown, a three-phase multi-meter energy metering box includes a box body 1, a box door 2 on the front of the box body 1, a three-phase energy meter 4 fixedly installed inside the box body 1 by a mounting bracket 3, and a fixing column 5 fixedly installed inside the box body 1.
[0029] The screw 6, which is installed in the internal thread of the fixed column 5, is used to push the pressure plate 7 to move linearly, so that the pressure plate 7 drives the anti-pull mechanism 8 to move synchronously.
[0030] The anti-pull mechanism 8 includes a rotating fixing component 81 rotatably mounted on the top of the pressure member 82. The pressure plate 7 pushes the pressure member 82 to drive the pressure ring 84 to abut against the expansion fixing component 83, so that the expansion fixing component 83 abuts against the cable.
[0031] See attached document Figures 2 to 5 In this embodiment, the interior of the box 1 is provided with a partition to separate the metering chamber and the wire threading chamber, and the box door 2 is hinged to the box 1.
[0032] In the above embodiment, the main switch can be installed through the wiring cavity, and multiple three-phase energy meters 4 can be fixedly installed inside the housing 1 through the mounting bracket 3 provided inside the metering cavity.
[0033] Furthermore, four sets of fixing posts 5 are installed inside the housing 1, and the screw 6 passes through the pressure plate 7 and is threaded to the fixing posts 5. Therefore, when the pressure plate 7 is rotated, the pressure plate 7 can simultaneously push the anti-pull mechanism 8 to move, so that the anti-pull mechanism 8 can clamp and fix the cable entering the housing 1.
[0034] Specifically, the top of the pressure member 82 of the anti-pull mechanism 8 is rotatably mounted with a rotating fixing component 81, wherein the rotating fixing component 81 includes a rotating cylinder 811, and an adjusting ring 812 is vertically slidably mounted on the outside of the rotating cylinder 811. An elastic band 814 is fixedly connected between the rotating cylinder 811 and the fixing ring 816. The rotating cylinder 811 passes through the pressure plate 7 and rotates with the pressure member 82, and the fixing ring 816 is fixedly mounted with the housing 1.
[0035] More specifically, since there is a spring 813 between the adjusting ring 812 and the rotating cylinder 811, after pushing the adjusting ring 812 to drive the positioning rod 815 away from the pressure member 82, the adjusting ring 812 can drive the rotating cylinder 811 to rotate, so that the elastic band 814 can spirally wrap around the surface of the cable, and the elastic band 814 can fix the cable inside the anti-pull mechanism 8.
[0036] It should be noted that the cable can be initially fixed by rotating the fixing assembly 81, while the cable can be further fixed by the multiple expansion fixing assemblies 83 arranged between the multiple pressure members 82.
[0037] Please refer to the appendix for details. Figure 2 , Figure 5 and Figure 6 The expansion fixing assembly 83 includes a connecting cylinder 831 that is slidably mounted on the pressure ring 84 and the pressure member 82. A spring 833 is fixedly installed inside the connecting cylinder 831. Due to the special shape design of the spring 833, the spring 833 can fix the cable. The connecting cylinder 831 and the pressure ring 834 can be connected into a whole by the limiting rod 832.
[0038] It is worth noting that when the screw 6 is turned, the screw 6 can push the pressure plate 7 to drive the pressure member 82 to move linearly. The movement of the pressure member 82 can drive the pressure ring 84 to move synchronously, so that the pressure ring 84 pushes the spring 833 to compress inside the connecting cylinder 831. The compression of the connecting cylinder 831 can abut against the cable, thereby fixing the cable.
[0039] The working principle of this utility model is as follows: After the cable is fed into the interior of the housing 1 through the anti-pull mechanism 8, the positioning rod 815 can be moved away from the interior of the pressure member 82 by pushing the adjusting ring 812 upward. By rotating the adjusting ring 812, the rotating cylinder 811 is rotated, causing one end of the elastic band 814 to rotate and spirally wrap around the surface of the cable. After the cable is initially fixed, the pressure plate 7 can be pushed to abut against the pressure member 82 by rotating the screw 6. The pressure member 82 pushes the pressure ring 84 to compress the spring 833 inward. After the spring 833 fixes the cable, the cable can be prevented from being pulled from the interior of the housing 1.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
