Description

Technical Field

[0001] This utility model relates to the field of meter box technology, specifically to a meter box that facilitates the observation of connectors. Background Technology

[0002] A meter box is a protective device specifically designed for installing electrical energy metering instruments. It is used to fix and install electrical meters, current transformers, and other power instruments, and to provide them with reliable protection and insulation.

[0003] Chinese Patent Publication No. CN203287409U discloses "An Electric Meter Box", which includes a meter box shell composed of a cover and a base plate. The front of the cover has six observation windows for the electric meters, and a wiring port is provided below the observation windows. The side of the cover has ventilation openings. The electric meter box using this utility model has a compact structure, occupies a small area, is easy to install, and can accommodate a large number of electric meter boxes. It is convenient for observing and recording the electric meter readings. The wiring port facilitates wiring and maintenance, and the ventilation openings ensure that the inside of the electric meter box is cool and dry.

[0004] While existing technology can ensure that the inside of the meter box is cool and dry, it results in low maintenance efficiency, leading to wasted costs and time. Replacing or repairing internal components usually requires disassembly and reinstallation using tools such as screwdrivers, increasing work time costs and downtime. At the same time, anyone can easily open the meter box during use, increasing the risk of illegal tampering or damage, such as the increased probability of electricity theft. Utility Model Content

[0005] The purpose of this utility model is to provide an electric meter box that facilitates the observation of connectors, solving the problems of low maintenance efficiency, wasted costs and time, and the need for tools such as screwdrivers to disassemble and reinstall internal components during use, which increases working time and downtime. In addition, anyone can easily open the electric meter box during use, increasing the risk of illegal tampering or damage, such as the increased probability of electricity theft.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An electric meter box for easy observation of connectors includes a box body, a quick-release assembly inside the box body, and a door opening assembly inside the box body.

[0008] The quick-release assembly includes multiple fixing plates, and each fixing plate has a slider slidably embedded inside. Each fixing plate has a large spring inside, and one side of the outer surface of each large spring is fixedly connected to one side of the outer surface of the slider. One side of the inner wall of the box is fixedly connected to multiple base plates, and each fixing plate is fixedly connected to the top of the outer surface of the base plate.

[0009] The door opening assembly includes multiple fixed frames, each with a sliding groove inside. A second connecting post is slidably embedded inside each sliding groove, and a second connecting plate is rotatably sleeved on the outer surface of each of the second connecting posts. A third connecting plate is fixedly connected to one side of the outer surface of each of the second connecting plates, and a transparent door is fixedly connected to one side of the outer surface of each of the third connecting plates.

[0010] Preferably, an insertion post is fixedly connected to one side of the outer surface of each of the plurality of sliders, a second limiting block is fixedly connected to one side of the outer surface of each of the plurality of sliders, and a pushing post is fixedly connected to one side of the outer surface of each of the plurality of sliders.

[0011] Preferably, a fourth limiting block is fixedly connected to one side of the outer surface of each of the plurality of fixed plates, and a third limiting block is fixedly connected to one side of the outer surface of each of the plurality of sliders.

[0012] Preferably, a fixing block is fixedly connected to one side of the outer surface of each of the plurality of fixing plates, and a fixing post is fixedly connected to one side of the outer surface of each of the plurality of fixing blocks. A sliding rod is slidably embedded inside each of the plurality of fixing posts, and a first limiting block is fixedly connected to one side of the outer surface of each of the plurality of sliding rods. A limiting plate is fixedly connected to one side of the outer surface of each of the plurality of sliding rods, and a small spring is wound around the outer surface of each of the plurality of sliding rods.

[0013] Preferably, an output column is rotatably embedded inside one side of one of the plurality of fixing frames, and an output plate is rotatably sleeved on the outer surface of the output column. A first connecting column is rotatably embedded inside the output plate, and a first connecting plate is rotatably sleeved on the outer surface of the first connecting column. A connecting rod is rotatably embedded inside the second connecting plate, and the connecting rod is rotatably embedded inside the sliding groove. The first connecting column is rotatably embedded inside the sliding groove.

[0014] Preferably, a rotary motor is fixedly connected to one side of the outer surface of one of the plurality of fixing frames, and the output shaft of the rotary motor is fixedly connected to the output column.

[0015] Preferably, each of the outer surfaces of the plurality of base plates is provided with an internal element, and the plurality of insertion posts are slidably embedded inside the internal element.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] 1. When internal components need to be installed, slide the slider towards the large spring by holding the push column. By squeezing the large spring, the slider slides and engages with the first and second limit blocks. The first limit block is trapezoidal in shape. The internal component is then placed between multiple fixed plates. Pulling the slide rod outward moves the slider, which in turn moves the first limit block. The movement of the first limit block releases the engagement limit, and the large spring pushes the slider out. As the slider is pushed out, the third and fourth limit blocks re-limit it to prevent it from slipping. This technical solution completes the engagement of multiple internal components, improving maintenance efficiency and reducing downtime.

[0018] 2. When the transparent cabinet door needs to be opened, the rotary motor is activated, which drives the output column to rotate. The rotation of the output column, in turn, drives the output plate to rotate. The rotation of the output plate, through the first connecting column, drives the first connecting plate to move. The first connecting plate, through the connecting rod, drives the second connecting plate to move. The second connecting plate is connected to the transparent cabinet door through the third connecting plate. Therefore, by rotating the motor, the second connecting plate slides along the slide groove, thereby changing the transparent cabinet door from its initial state of being flush with the cabinet body to a state perpendicular to the cabinet body. Through the above technical solution, safety is improved and unauthorized operation is prevented. Only authorized personnel can open the cabinet for operation. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-4 An electric meter box for easy observation of connectors includes a box body 1, a quick-release assembly inside the box body 1, and a door opening assembly inside the box body 1.

[0026] The quick-release assembly includes multiple fixing plates 2, and each fixing plate 2 has a slider 3 slidably embedded inside it. Each fixing plate 2 has a large spring 301 inside it, and one side of the outer surface of each large spring 301 is fixedly connected to one side of the outer surface of the slider 3. One side of the inner wall of the housing 1 is fixedly connected to multiple base plates 101, and multiple fixing plates 2 are fixedly connected to the top of the outer surface of the base plate 101.

[0027] The door opening assembly includes multiple fixing brackets 8, and each fixing bracket 8 has a sliding groove 801 inside. Each sliding groove 801 has a second connecting post 606 slidably embedded inside. Each second connecting post 606 has a second connecting plate 605 rotatably sleeved on its outer surface. Each second connecting plate 607 is fixedly connected to one side of its outer surface. Each third connecting plate 607 is fixedly connected to one side of its outer surface.

[0028] With the above technical solution, when it is necessary to install the internal component 5, the slider 3 is slid towards the large spring 301 by hand-pushing the push column 305. The slider 3 is slid by squeezing the large spring 301. The first limiting block 205 and the second limiting block 303 are engaged. The first limiting block 205 is trapezoidal in shape. At this time, the internal component 5 is placed between multiple fixed plates 2. The slider 202 is pulled outward. The movement of the slider 202 drives the first limiting block 205 to move. The movement of the first limiting block 205 releases the engagement limit. At this time, the slider 3 is pushed out by the large spring 301. When the slider 3 is pushed out, it is again limited by the small spring 204 and the fourth limiting block 207, thereby preventing the slider 3 from slipping. With the above technical solution, the engagement of multiple internal components 5 is completed, improving operation and maintenance efficiency and shortening downtime.

[0029] With the above technical solution, when it is necessary to open the transparent box door 4, the rotary motor 6 is turned on, which drives the output column 601 to rotate. The rotation of the output column 601 drives the output plate 602 to rotate. The rotation of the output plate 602 drives the first connecting plate 604 to move through the first connecting column 603. The first connecting plate 604 drives the second connecting plate 605 to move through the connecting rod 7. The second connecting plate 605 is connected to the transparent box door 4 through the third connecting plate 607. Therefore, the rotary motor 6 drives the second connecting plate 605 to slide along the slide groove 801, thereby changing the transparent box door 4 from its initial state of being attached to the box body 1 to a state of being perpendicular to the box body 1. With the above technical solution, safety is improved and unauthorized operation is prevented. Only authorized personnel can open the box body 1 for operation.

[0030] Specifically, an insertion post 302 is fixedly connected to one side of the outer surface of multiple sliders 3, a second limiting block 303 is fixedly connected to one side of the outer surface of multiple sliders 3, and a pushing post 305 is fixedly connected to one side of the outer surface of multiple sliders 3.

[0031] Using the above technical solution, the slider 3 is slid towards the large spring 301 by hand-pushing the push column 305, and the slider 3 is slid by squeezing the large spring 301.

[0032] Specifically, a fourth limiting block 207 is fixedly connected to one side of the outer surface of multiple fixed plates 2, and a third limiting block 304 is fixedly connected to one side of the outer surface of multiple sliders 3.

[0033] Through the above technical solution, the first limiting block 205 and the second limiting block 303 are engaged, and the third limiting block 304 and the fourth limiting block 207 are used for further limiting.

[0034] Specifically, a fixing block 201 is fixedly connected to one side of the outer surface of multiple fixing plates 2, and a fixing post 203 is fixedly connected to one side of the outer surface of multiple fixing blocks 201. A sliding rod 202 is slidably embedded inside the multiple fixing posts 203. A first limiting block 205 is fixedly connected to one side of the outer surface of multiple sliding rods 202. A limiting plate 206 is fixedly connected to one side of the outer surface of multiple sliding rods 202. A small spring 204 is wrapped around the outer surface of multiple sliding rods 202.

[0035] Through the above technical solution, by pulling the slide bar 202 outward, the movement of the slide bar 202 drives the first limiting block 205 to move, and the movement of the first limiting block 205 releases the locking limit.

[0036] Specifically, an output post 601 is rotatably embedded inside one side of one of the multiple fixed frames 8, and an output plate 602 is rotatably sleeved on the outer surface of the output post 601. A first connecting post 603 is rotatably embedded inside the output plate 602, and a first connecting plate 604 is rotatably sleeved on the outer surface of the first connecting post 603. A connecting rod 7 is rotatably embedded inside the second connecting plate 605, and the connecting rod 7 is rotatably embedded inside the second connecting plate 605. The connecting rod 7 is slidably embedded inside the slide groove 801, and the first connecting post 603 is slidably embedded inside the slide groove 801.

[0037] Through the above technical solution, the output column 601 rotates, thereby driving the output plate 602 to rotate. The rotation of the output plate 602 drives the first connecting plate 604 to move through the first connecting column 603. The first connecting plate 604 drives the second connecting plate 605 to move through the connecting rod 7. The second connecting plate 605 is connected to the transparent door 4 through the third connecting plate 607.

[0038] Specifically, a rotary motor 6 is fixedly connected to one side of the outer surface of one of the multiple fixed brackets 8, and the output shaft of the rotary motor 6 is fixedly connected to the output column 601.

[0039] The above technical solution uses a rotary motor 6 to drive the output column 601 to rotate.

[0040] Specifically, internal components 5 are provided on the top of the outer surface of multiple base plates 101, and multiple insertion posts 302 are slidably embedded inside the internal components 5.

[0041] The above technical solution limits the internal component 5 by inserting the post 302.

[0042] In use, when it is necessary to install the internal component 5, the slider 3 is slid towards the large spring 301 by holding the push column 305. The slider 3 slides by squeezing the large spring 301, and is engaged by the first limiting block 205 and the second limiting block 303. The first limiting block 205 is trapezoidal in shape. The internal component 5 is then placed between multiple fixing plates 2. Pulling the slide rod 202 outwards moves the first limiting block 205, releasing the engagement. The large spring 301 then pushes the slider 3 out. As the slider 3 is pushed out, it is again limited by the third limiting block 304 and the fourth limiting block 207 to prevent it from slipping. This technical solution completes the engagement of multiple internal components 5, improving efficiency. To improve operational efficiency and reduce downtime, when the transparent enclosure door 4 needs to be opened, the rotary motor 6 is activated, which drives the output column 601 to rotate. The rotation of the output column 601 drives the output plate 602 to rotate. The rotation of the output plate 602 drives the first connecting plate 604 to move via the first connecting column 603. The first connecting plate 604 drives the second connecting plate 605 to move via the connecting rod 7. The second connecting plate 605 is connected to the transparent enclosure door 4 via the third connecting plate 607. Therefore, the rotary motor 6 drives the second connecting plate 605 to slide along the slide groove 801, thereby changing the transparent enclosure door 4 from its initial state of being flush with the enclosure 1 to a state perpendicular to the enclosure 1. Through the above technical solution, safety is improved and unauthorized operation is prevented. Only authorized personnel can open the enclosure 1 for operation.

[0043] 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, the scope of which is defined by the appended claims and their equivalents.
