Description
Technical Field
[0001] This utility model relates to the installation of low-voltage boxes, and more particularly to a liftable buried low-voltage box. Background Technology
[0002] Low-voltage boxes are commonly used in network systems, and their number has surged with the development of technologies such as 5G and the Internet of Things.
[0003] Traditional low-voltage distribution boxes are typically installed on the ground or walls, occupying valuable urban space and often affecting the overall aesthetics. Especially in public areas such as parks, squares, and pedestrian streets, these obtrusive boxes disrupt the harmony of the landscape. With accelerating urbanization and increasing demands for environmental aesthetics, traditional ground-mounted low-voltage distribution boxes can no longer meet the needs of modern urban development, leading to the emergence of underground installation designs.
[0004] Traditional low-voltage boxes are usually installed on the ground or wall, making them easy to spot and susceptible to vandalism or theft.
[0005] On the other hand, buried low-voltage boxes need to address the technical issue of convenient maintenance. Utility Model Content
[0006] The present invention aims to solve at least one of the technical problems mentioned above, and to provide a liftable buried low-voltage box that is concealed and easy to maintain, ensuring a clean and aesthetically pleasing environment.

[0030] Support arm 300, finger end 310, hinge end 320, first rotating shaft 330, first mounting base 340;

[0032] Linkage rope 510, tension roller 520, second rotating shaft 521, second mounting base 522. Detailed Implementation
[0033] 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.
[0034] Reference Figures 1 to 7 This utility model provides a lifting buried low-voltage box, including a box body 100, a buried cylinder 200, and a support arm 300; the top of the box body 100 is provided with a handle 130; the buried cylinder 200 is provided with a limit port or a vertical rail, and the box body 100 is used to move up and down along the limit port or vertical rail to enter and exit the buried cylinder 200; the support arm 300 includes a finger end 310 and a hinge end 320 that is hinged to the buried cylinder 200. The finger end 310 is used to lean against the box body 100 based on its own weight, and is also used to lie down (swing) under the box body 100 based on its own weight when the box body 100 is higher than the support arm 300, so as to support the box body 100 that sinks down.
[0035] It is understandable that in the design of the buried low-voltage box, the buried cylinder 200 is connected to a cylinder cover. As for "relying on", it is understandable that the support arm 300 maintains an upward tilted posture with the support finger end 310 resting against the buried cylinder 200.
[0036] The buried cylinder 200 can be made of concrete; it can also be made of plastic prefabricated using molds and then buried on the ground / underground, or embedded in the ground / underground using concrete.
[0037] The underground casing 200 is buried in the ground. The electrical box body 100 needs to move up and down to enter and exit the underground casing 200. Therefore, it is understandable that the upper end of the underground casing 200 is open, and this opening may even be designed as a restriction opening to limit the direction of the electrical box body 100's lifting and lowering. In this design, the vertical rail design is saved, and the underground casing 200 is simplified. Vertical guide rods, etc., are equivalent replacements for the vertical rails.
[0038] In network design, the electrical components inside the electrical box 100 include low-voltage equipment such as optical modems, routers, switches, PoE switches, wireless APs, power modules, PDU power strips, telephone splitters, TV splitters / amplifiers, and / or IPTV set-top boxes.
[0039] The cables connecting the low-voltage equipment pass through an underground cable tray, through a waterproof connector in the buried casing 200, and then into the buried casing 200, before being connected in series with the electrical box body 100. The cable redundancy between the electrical box body 100 and the waterproof connector facilitates the raising and lowering of the electrical box body 100. Preferably, the electrical box body 100 is provided with another waterproof connector for the cables to pass through.
[0040] In some configurations, a cable chain trough connects the electrical box body 100 and the underground casing 200. The cables between the underground casing 200 and the electrical box body 100 are threaded through the cable chain trough. (Refer to...) Figures 1 to 4 The buried cylinder 200 is provided with a vertical shaft 230 to allow the cable carrier trough to bend and deform. The cable carrier trough can be seen in machine tool equipment. The cable carrier trough deforms with movement to prevent the cables, air pipes, etc. inside from being bent or knotted too much.
[0041] In some designs, the support arm 300 is directly pried open by hand, causing the support finger tip 310 to rise, thus preventing the electrical box body 100 from sinking. (Refer to...) Figures 1 to 7 In some configurations, a reset mechanism is also included, which is used to drive the finger end 310 of the support arm 300 to rise, so as to prevent the electrical box body 100 from sinking.
[0042] Reference Figures 2 to 4 The operation process of this utility model is as follows: when it is stationary (i.e. when the buried low-voltage box is idle or working quietly), the box body 100 and its low-voltage equipment are submerged in the buried cylinder 200 and the buried cylinder 200 is covered with a cylinder cover.
[0043] When it is necessary to maintain or replace the low-voltage equipment or wiring inside the electrical box 100, first lift the electrical box 100 using the handle 130, referring to... Figure 2 , Figure 5 During the process of the electrical box body 100 rising to gradually protrude from the buried cylinder 200, the support finger end 310 of the support arm 300 always relies on the side wall.
[0044] When the electrical box body 100 is higher than the support arm 300, the support finger tip 310 of the support arm 300 continues to swing downwards based on its own weight, so as to lie horizontally below the electrical box body 100. At this time, the electrical box body 100 can sink down to support the horizontally lying support arm 300; see reference. Figure 2 , Figure 5 There are two support arms 300, which are used to support the left and right ends of the electrical box body 100 respectively.
[0045] After the electrical box body 100 is maintained, the electrical box body 100 is first lifted up, and then the support arm 300 is driven to move upward to avoid it, and the electrical box body 100 is lowered down; when the lower end of the electrical box body 100 is lower than the support arm 300, the support arm 300 is released, and the support finger end 310 of the support arm 300 remains supported by the electrical box body 100 based on its own weight.
[0046] Reference Figure 3 The electrical box body 100 is integrally formed with an electrical compartment and a raised seat connected to the lower end of the electrical compartment. When the electrical compartment enters or exits the buried cylinder 200, the raised part remains in the buried cylinder, so that the electrical box body is always limited by the limit port when it is raised or lowered, so that the electrical compartment can be raised and lowered in a directional manner.
[0047] Compared with existing technologies, the beneficial effects of this application include: the lift-up buried design hides the equipment underground, raising it only when maintenance is needed, thus maintaining the cleanliness and aesthetics of the environment to the greatest extent; this design concept coincides with the current advocacy of "seamless" urban construction, making the facilities "disappear" from people's sight when not in use; the liftable mechanism enables the concealed installation and convenient maintenance of low-voltage equipment inside the electrical box, reducing the risk of theft; the double-layer sealed space of the buried cylinder and the electrical box body provides double protection for the low-voltage equipment. This protection not only targets moisture but also reduces the impact of various environmental factors such as temperature changes and chemical corrosion on the low-voltage equipment.
[0048] While the initial investment for a lift-up underground low-voltage distribution box may be higher than that of a traditional design, its advantages, such as reduced maintenance costs, extended equipment lifespan, and enhanced aesthetics, result in a more optimized overall lifecycle cost. This design's economic viability is particularly evident when considering the land and landscape value of prime urban areas.
[0049] Reference Figures 2 to 4 , Figure 7 In some embodiments of this utility model, the buried cylinder 200 is provided with a limiting part 210, which is used to limit the swing of the support arm 300, so that the finger end 310 of the support arm 300 rests on the buried cylinder 200 or lies horizontally in the lifting position.
[0050] Reference Figure 3 , Figure 4 , Figure 6 , Figure 7 The limiting part 210 is used to press the hinge end 320 of the support arm 300 so that the support arm 300 supports the electrical box body 100 in a lever manner.
[0051] Reference Figures 1 to 4 In some embodiments of this utility model, at least two support arms 300 are provided. One support arm 300 is connected to a handle 400 for driving its finger tip 310 to rise and avoid an obstacle. The support arm 300 is connected to other support arms 300 through a linkage rope 510. The support arm 300 is used to drive the other support arms 300 together to raise their finger tips 310 to avoid an obstacle.
[0052] Reference Figure 3 , Figure 4Two support arms 300 are provided. The finger end 310 of the left support arm 300 is connected to the handle 400, and the finger end 310 of the left support arm 300 is connected to the hinge end 320 of the right support arm 300 through a linkage rope 510. In this utility model, only the handle 400 needs to be pulled to drive all the support arms 300 to swing together to avoid the obstacle. That is, after the electrical box body 100 is maintained, the worker can first lift the electrical box body 100 with his right hand and pull the handle 400 with his left hand to make all the support arms 300 swing upwards to avoid the obstacle; then, while keeping the handle 400 temporarily in place, the electrical box body 100 is lowered; when the lower end of the electrical box body 100 is lower than the support arm 300, the handle 400 can be released, and the finger end 310 of the support arm 300 remains supported by the electrical box body 100 based on its own weight.
[0053] Reference Figure 3 In some embodiments of this utility model, the support arm 300 has a first rotating shaft 330 integrally formed on both sides. The first rotating shaft 330 is threaded into a corresponding first mounting seat 340, and the first mounting seat 340 is connected to the buried cylinder 200 by screws. In this utility model, the two rotating shafts of the support arm 300 can be directly optical shafts, making it convenient to assemble and disassemble the support arm 300 and the buried cylinder 200; the rotating structure of the support arm 300 is simple and practical.
[0054] Reference Figure 3 In some embodiments of this utility model, the middle part of the linkage rope 510 is wrapped around multiple tension rollers 520. The two ends of the tension rollers 520 are integrally formed with second rotating shafts 521. The second rotating shafts 521 are threaded into corresponding second mounting seats 522. The second mounting seats 522 are connected to the buried cylinder 200 by screws.
[0055] In some embodiments of this utility model, the buried cylinder 200 is made of plastic, and the first mounting base 340 and the second mounting base 522 are installed to the buried cylinder 200 by self-tapping screws. That is, the buried cylinder 200 can be first installed with components such as the support arm 300 and the tension roller 520, and then the buried cylinder 200 is built into the ground. The electrical box body 100 is used to install low-voltage equipment, cables, and cable trays. Then, the support arm 300 is driven to move aside, straightening the electrical box body 100 and sinking it into the buried cylinder 200. Preferably, the redundant cable between the electrical box body 100 and the buried cylinder 200 is ≥1.3 times the height of the electrical box body 100.
[0056] Reference Figures 1 to 4In some embodiments of this utility model, the buried cylinder 200 includes a boss 220 for protruding from the ground, and the handle 400 includes a pull ring 410 and a pull rope 420 for connecting the corresponding support arm 300. The boss 220 is provided with a through hole for the pull rope 420 to pass through, and the through hole also limits the pull rope 420 to prevent the pull rope 420 from obstructing the lifting and lowering of the electrical box body 100. The pull rope 420 extends directly to the pull ring 410 through the through hole. The pull rope 420 can be relatively short and is not easy to redundantly wrap around the support arm 300. The boss 220 is provided with a countersunk hole for storing the wristband.
[0057] In some embodiments of this utility model, a cylinder cover is also included. The buried cylinder 200 includes a protrusion 220 for protruding from the ground. The cylinder cover is used to cover the protrusion 220. The buried low-voltage box has high waterproof performance and prevents rainwater from splashing in.
[0058] The cylinder cover is used to cover the boss 220. Therefore, in some designs, the cylinder cover is an integral cover, which covers the boss 220 from top to bottom. In this design, the left and right ends of the cylinder cover generally need to be connected to the boss 220 through the first key lock, so there are many key locks and the unlocking of the cylinder cover is more troublesome; in addition, during maintenance, the cylinder cover is completely detached from the buried cylinder 200, and the cylinder cover is easily mistakenly placed in other places, which will lead to the search, such as being mistakenly placed in the engineering vehicle and being towed away with the vehicle during maintenance.
[0059] In some embodiments of this utility model, the cylinder cover is divided into a first part and a second part that are hinged together. The first part is used to cover the top of the boss 220 and the three side walls of the boss 220. The second part is used to cover the other side wall of the boss 220. One end of the first part that is offset from the second part is used to hinge the boss 220. One end of the second part that is offset from the first part is connected to the other side wall of the boss 220 through a first key lock. The first part covers the opening of the buried cylinder 200 through a first sealing ring.
[0060] In some embodiments of this utility model, a cylinder cover is also included. The buried cylinder 200 includes a protrusion 220 for protruding from the ground. The upper end of the protrusion 220 is provided with a recess for sinking the handle 400. The cylinder cover is used to cover the protrusion 220.
[0061] Reference Figure 2 , Figure 3 In some embodiments of this utility model, the electrical box body 100 includes a box shell 110 and a box door 120. One end of the box door 120 is hinged to the box shell 110, and the other end is connected to the box door 120 through a second key lock 140, so that the box door 120 covers the opening of the box shell 110. The box door 120 is connected to the box shell 110 through a second sealing ring.
[0062] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
