Description

Technical Field

[0001] This utility model relates to the technical field of electricity metering boxes, specifically an electricity metering box that is easy to assemble and disassemble. Background Technology

[0002] An electricity meter box (also called a power meter box) is a device used to install and protect electricity meters and related power metering devices. It is commonly used in residential, commercial, or industrial buildings as an important component of electricity metering and distribution. The main function of an electricity meter box is to measure and record the electricity consumption of a building or area and to ensure the safe operation of electrical facilities.

[0003] For example, a conveniently detachable electricity metering box, disclosed in CN221978464U, includes a box body, a fixing plate, a limiting frame, a fixing bracket, a return spring, and moving blocks. Two fixing plates are connected to the upper front of the box body. A limiting frame and two fixing brackets are located at the front of the box body. Two limiting parts on the left side of the limiting frame limit the fixing plates. Two return springs connect the limiting frame to the box body. Two pairs of moving blocks are connected to the left side of the limiting frame. By pulling the limiting frame, the limiting parts disengage from the slots, at which point the locking part abuts against the inclined part, thus fixing the limiting frame and allowing for quick removal of the electricity metering box. Then, by pressing the locking part with the sliding block, the locking part disengages from the inclined part of the trapezoidal plate, causing the limiting part to re-engage into the slot, thus re-fixing the box body. This method is simple to operate, reduces manual labor, and improves disassembly and assembly efficiency.

[0004] The aforementioned patent proposes that if the locking part continues to move to the left, it will separate from the inclined part, and the locking part will no longer press against the adjacent inclined part. The inclined part will then return to its original position, and the locking part will then engage with the adjacent inclined part. Simultaneously, the movement of the limiting bracket to the left will cause the limiting part to move to the left as well. The limiting part will disengage from the fixing plate slot and will no longer limit the fixing plate, allowing the electricity metering box to be removed directly. However, in actual use, when the locking part and the inclined part are pressed against each other, because they are both made of elastic materials, repeated deformation will occur. Over long-term use, repeated deformation will lead to material fatigue, reducing the elasticity and pressure-bearing capacity of the locking part and the inclined part, thus affecting the overall locking effect of the device. Utility Model Content

[0005] The purpose of this utility model is to provide an easy-to-disassemble and disassemble power metering box to solve the problem mentioned in the background art that repeated deformation during long-term use will lead to material fatigue, reduce the elasticity and pressure bearing capacity of the snap-fit ​​and inclined parts, and thus affect the snap-fit ​​effect of the entire device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily detachable and assembleable electricity metering box, comprising an electricity metering box, a connecting structure installed at the rear end of the electricity metering box, a locking component installed at the rear end of the electricity metering box, two sets of locking components, a water guide strip installed on the outer side of the rear end of the electricity metering box, and an external frame installed through the rear end of the electricity metering box.

[0007] The connection structure includes a fixed frame and a frame groove inside the fixed frame. The front end of the fixed frame has a positioning hole, and there are two sets of positioning holes.

[0008] Preferably, a rain cover is installed on one side of the outer frame, and a rubber ring is installed at one end of the rain cover.

[0009] Preferably, the locking component includes a plug rod and a top through groove formed at the top of the plug rod, and an outer limiting plate is installed at one end of the plug rod.

[0010] Preferably, a connecting ring is installed at the top of the fixed frame, a bottom hole is provided through the bottom of the frame groove, and a lead wire hole is provided at the front of the fixed frame.

[0011] Preferably, an inner slide bar is slidably installed at the upper end of the inner slide bar, and a rotating shaft is movably installed at the bottom end of the inner slide bar, with the lower end of the rotating shaft penetrating the bottom end of the fixed frame.

[0012] Preferably, the upper outer surface of the rotating shaft is provided with threaded grooves, and two sets of threaded grooves are provided.

[0013] Preferably, a through groove is provided at the middle end of the inner slide bar, a transverse connecting strip is installed inside the through groove, and inserts are installed at the top end of the through groove and the bottom end of the transverse connecting strip.

[0014] Preferably, the inner slide bar has inner grooves on both sides and on the inner wall of the frame groove, and sliders are installed on both sides of the inner slide bar.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model discloses an easy-to-assemble and disassemble electricity metering box. By holding the bottom end of the rotating shaft and rotating it, the rotating shaft moves upward along the bottom end of the fixed frame. The sliders installed on both sides of the inner slide bar will move upward along the inside of the inner groove. The insert will move out from the inside of the top through groove. The electricity metering box can be taken out from the front end of the connecting structure. The locking component moves out from the positioning hole. Since there are two sets of locking components and two sets of positioning holes, the electricity metering box can still be kept stable when it is removed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-4 An easy-to-assemble and disassemble electricity metering box includes an electricity metering box 1, a connecting structure 2 installed at the rear end of the electricity metering box 1, a locking component 15 installed at the rear end of the electricity metering box 1, two sets of locking components 15, a water guide strip 11 installed on the outer side of the rear end of the electricity metering box 1, an external frame 12 installed through the rear end of the electricity metering box 1, a rain cover 13 installed on one side of the external frame 12, and a rubber ring 14 installed at one end of the rain cover 13.

[0025] The connecting structure 2 includes a fixed frame 21 and a frame groove 25 opened inside the fixed frame 21. The front end of the fixed frame 21 is provided with a positioning hole 26. There are two sets of positioning holes 26. The position of the locking member 15 is aligned with the position of the positioning hole 26.

[0026] The locking component 15 includes a plug 151 and a top through groove 153 formed at the top of the plug 151.

[0027] A connecting ring 22 is installed at the top of the fixed frame 21, a bottom hole 24 is opened through the bottom of the frame groove 25, and a lead wire hole 23 is opened at the front end of the fixed frame 21. The lead wire hole 23 and the bottom hole 24 are aligned in front and back positions, and the position of the lead wire hole 23 is aligned with the position of the rain cover 13.

[0028] An inner slide bar 211 is slidably installed at the upper end of the inner slide bar 211, and a rotating shaft 215 is movably installed at the bottom end of the inner slide bar 211. The lower end of the rotating shaft 215 passes through the bottom end of the fixed frame 21. A threaded groove 216 is provided on the outer surface of the upper end of the rotating shaft 215. Two sets of threaded grooves 216 are provided to facilitate fixing the position of the inner slide bar 211.

[0029] A central groove 212 is provided through the middle of the inner slide bar 211. A transverse connecting bar 213 is installed horizontally inside the central groove 212. Inserts 214 are installed at the top of the central groove 212 and the bottom of the transverse connecting bar 213. The inserts 214 are adapted to the top groove 153.

[0030] Inner grooves 27 are provided on both sides of the inner slide bar 211 and on the inner wall of the frame groove 25. Slider 217 is installed on both sides of the inner slide bar 211. The slider 217 slides within the inner groove 27 to limit the movement angle of the inner slide bar 211.

[0031] In this embodiment: After opening the electricity metering box 1, the wire plug is removed from inside the electricity metering box 1. The bottom end of the rotating shaft 215 is held and rotated. When the rotating shaft 215 rotates upward along the bottom end of the fixed frame 21, the sliders 217 installed on both sides of the inner slide bar 211 will move upward along the inside of the inner groove 27. When the inner slide bar 211 moves upward, it will drive the horizontal connecting bar 213 and the two sets of plug bars 214 to move. The plug bars 214 move out from the inside of the top through groove 153. At this time, the operator... By holding the power meter box 1, the power meter box 1 can be removed from the front end of the connecting structure 2. The locking component 15 is moved out from the positioning hole 26. Since there are two sets of locking components 15 and two sets of positioning holes 26, the power meter box 1 can still be kept stable when it is removed. When moving the power meter box 1, the wire moves inside the rubber ring 14, which makes it easier for operators to remove the power meter box 1 for maintenance and avoids the wire being pulled and messed up, which would affect the subsequent installation and normal operation of the power meter box 1.

[0032] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 An outer limiting plate 152 is installed at one end of the insertion rod 151. The diameter of the outer limiting plate 152 is larger than the diameter of the insertion rod 151, which facilitates the clamping of the positioning component 15. The diameter of the positioning hole 26 is the same as the diameter of the outer limiting plate 152.

[0033] In this embodiment: After the electricity metering box 1 is repaired, the locking component 15 is aligned with the positioning hole 26, and the electricity metering box 1 is pushed towards one side of the connecting structure 2. When one end of the outer limit plate 152 contacts the inner side of the frame groove 25, the rotating shaft 215 is held and rotated, causing the rotating shaft 215 to move downward. When the inner slide bar 211 moves downward, it will drive the insert bar 214 to move downward. The lower end of the insert bar 214 is inserted into the interior of the top through groove 153. The provided insert rod 151, positioning hole 26, insert bar 214, inner slide bar 211 and cross joint bar 213 will protect the metering box. The connection structure 2 supports the installation of the electricity metering box 1 and prevents the electricity metering box 1 from moving. Since the upper outer surface of the rotating shaft 215 has two sets of threaded grooves 216, the threaded grooves 216 fix the rotating shaft 215 at different positions to ensure the stability of the inner slide bar 211 inside the frame groove 25, and prevent the inner slide bar 211 from falling off, which would affect the disassembly and assembly of the electricity metering box 1. After the electricity metering box 1 is installed, one end of the wire can be inserted into the inside of the electricity metering box 1 to maintain the reasonable planning and use of the wire and avoid the wires being messy.
