Description

Technical Field

[0001] The utility model relates to the technical field of electric power meter boxes, and more specifically to a single-phase one-meter electric energy meter box. Background Art

[0002] An energy meter box is an electrical device designed specifically for the precise measurement and control of energy consumption. It is usually installed at the access point of the power supply line to measure and record the user's electricity consumption. This device is commonly found in residential areas, commercial buildings, industrial sites and other power supply and usage scenarios. It has an electric meter installed inside, also known as an energy meter. This is the core part of the meter box, which is used to measure and accumulate the amount of electrical energy consumed by the circuit in real time.

[0003] Usually, the steps for fixing the energy meter to the meter box are to hold the energy meter with one hand and hold a screwdriver with the other hand to fix the energy meter in the meter box through screws. This fixing method requires holding the energy meter for a long time, which will cause arm soreness and is not convenient for workers to install and fix the energy meters in batches. Although some meter boxes are equipped with a quick installation structure, the fixing ability is poor, which affects the stability during use.

[0004] A single-phase meter installer is disclosed in the Chinese utility model patent application number: CN218719869U, the structure of which includes a rubber plate, a middle plate and a side plate, the middle plate is fixedly installed on the rubber plate, and the side plates are slidably installed on both sides of the middle plate. Although this single-phase meter installer has the function of facilitating the installation of the electric energy meter in the metering box, it uses a spring for fixing. After long-term use, the spring will experience metal fatigue, resulting in the electric energy meter not being firmly fixed. At the same time, when the box is shaken, the electric energy meter will also shake, thereby affecting the stability of the electric energy meter.

[0005] Therefore, it is necessary to propose a single-phase single-meter electric energy meter box to solve the above problems. Utility Model Content

A pull rope 115 moves in the sliding groove 114. When the pull rope 115 is pulled, the pull rope 115 drives the clamping frame 106 to move. One end of the pull rope 115 is connected to a rope handle 119. The initial position of the rope handle 119 is on the cross bar 113. The pull rope 115 is slidably connected in the sliding groove 114, and one end of the pull rope 115 is fixedly connected to the clamping frame 106.

[0033] Specifically, refer to Figure 3 and Figure 6One end of the bidirectional threaded rod 110 is fixedly connected to a worm wheel 116, and a worm 117 is transmission-connected to the outer wall of the worm wheel 116. The worm wheel 116 and the worm 117 cooperate with each other and have a self-locking ability, which plays a role in fixing the bidirectional threaded rod 110. The worm 117 is rotatably connected to the inner wall of the box body 101, and the other end of the worm 117 is fixedly connected to a rotating handle 118.

[0034] Specifically, refer to Figure 3 and Figure 5 One end of the pull rope 115 away from the clamping frame 106 is fixedly connected to a rope handle 119, and the pull rope 115 can be pulled out of the cross bar 113 by pulling the rope handle 119. The rope handle 119 is located at one end of the cross bar 113 away from the worm gear 116.

[0035] Specifically, refer to Figure 3 and Figure 6 A cover plate 120 is connected to the top of the sliding frame 103, and a support seat 121 is fixedly connected to the middle of the sliding frame 103. The support seat 121 supports the cover plate 120 and the bidirectional threaded rod 110. The cover plate 120 can prevent foreign matter from entering, and the support seat 121 is rotatably connected to the bidirectional threaded rod 110.

[0036] Specifically, refer to Figure 4 A baffle 122 is fixedly connected to one side of the clamping frame 106, and the baffle 122 is arranged on the side away from the fixed plate 102, so that the baffle 122 can block the front of the electric energy meter to prevent the electric energy meter from falling out. A wiring groove 123 is arranged at the bottom of the support plate 104.

[0037] Specifically, refer to Figure 3 and Figure 6 A contact pad 124 is fixedly connected to the bottom of the fixing claw 111 . The contact pad 124 can act as a cushion when the fixing claw 111 contacts the vertical plate 112 . The fixing claw 111 is slidably connected on the sliding rod 109 .

[0038] Specifically, refer to Figure 1 and Figure 2 The top of the box body 101 is connected to a front cover 125 through a hinge. The front cover 125 is provided with a transparent cover plate for conveniently observing the value of the internal electric energy meter. The bottom of the box body 101 is provided with a slot for the connection cables to pass through.

[0039] In this embodiment, the box 101 is fixed on the wall where it is needed. When the electric energy meter is installed in the box 101, one hand holds the electric energy meter and the other hand holds the rope handle 119. The rope handle 119 is pulled to the left. The rope handle 119 drives the pull rope 115 to move in the sliding groove 114. When moving, the end of the pull rope 115 drives the clamping frame 106 to move toward the support plate 104, so that the distance between the clamping frame 106 and the support plate 104 becomes smaller, and the spring 108 between them is compressed, and the two clamping frames are The distance between the two clamping frames 106 becomes larger, so that the electric energy meter can be placed between the two clamping frames 106, and then the rope handle 119 is loosened, and the spring 108 between the clamping frame 106 and the support plate 104 is reset and stretched, driving the clamping frame 106 and the pull rope 115 to reset, so that the two clamping frames 106 move toward the direction of the electric energy meter, and then the electric energy meter is clamped in the middle, and the baffle 122 on the clamping frame 106 contacts the front of the electric energy meter, which has a limiting effect on the electric energy meter and prevents the electric energy meter from being separated from between the two clamping frames 106;

[0040] When fixing the distance between the two clamping frames 106, manually rotate the rotating handle 118, and the rotating handle 118 drives the worm wheel 116 to rotate through the worm 117. The worm wheel 116 pushes the symmetrical fixing claws 111 to move toward each other through the bidirectional threaded rod 110. When the fixing claws 111 move to the corresponding position, the fixing claws 111 will come into contact with the vertical plate 112 on the top of the clamping frame 106, so that the position of the clamping frame 106 is limited by the vertical plate 112 to prevent the distance between the two clamping frames 106 from changing due to shaking, thereby causing the electric energy meter to be clamped unstable. In addition, the worm wheel 116 and the worm 117 have a self-locking effect, which can avoid the situation where the distance between the two fixing claws 111 becomes larger due to the reversal of the bidirectional threaded rod 110. The wiring groove 123 between the two support plates 104 is used for the wires on the electric energy meter to pass through.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
