Description

Technical Field

[0001] This utility model relates to the field of building low-voltage electrical technology, and in particular to a low-voltage electrical distribution structure for building floors. Background Technology

[0002] As modern buildings develop towards intelligence and multifunctionality, low-voltage systems have become one of the core infrastructures for building operations. These systems encompass multiple key subsystems such as communication, networking, monitoring, and security, directly impacting users' daily office and living environments, as well as building management efficiency. Currently, the distribution of low-voltage signals across building floors generally adopts a "centralized control + layered deployment" architecture. This involves a main switch located in the building's computer room to manage overall signal distribution. The main switch then connects to relay cabinets on each floor via cables. Sub-switches within these relay cabinets are responsible for distributing low-voltage signals to the various user terminals on that floor.

[0003] In traditional distributed systems, when a floor needs cable replacement due to aging wiring or when a branch switch malfunctions and requires shutdown for maintenance, the conventional procedure is to first disconnect the low-voltage connection between that floor and the main switch or adjacent floors before carrying out maintenance work. This results in all low-voltage terminals on that floor being out of service during the maintenance period (especially in places like hospitals, office buildings, and data centers), making it impossible to guarantee normal circuit use for users' floors during line maintenance. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a low-voltage electrical distribution structure for building floors.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a low-voltage distribution structure for building floors, comprising a main switch, multiple relay cabinets disposed on one side of the main switch, and branch switches fixed in the relay cabinets and connected to the main switch circuit. The number of branch switches is equal to the number of relay cabinets and their positions correspond one-to-one. A mounting shell is fixed inside the relay cabinet, and two main power strips are slidably disposed inside the mounting shell. The two main power strips are connected by a wire circuit. Main plugs fixed to the mounting shell are penetrated through the side walls on both sides of the mounting shell. One of the main plugs is connected to the branch switch circuit via a wire, and the other main plug is connected to the user's product circuit via a wire. The main plugs are plugged into the corresponding main power strips. A branch power strip is provided inside the mounting housing. The branch power strip is connected to the two main power strips via a wire. The top and bottom of the mounting housing are both provided with branch plugs fixed to the mounting housing. The lower branch plug is connected to the branch plug on the lower branch transfer cabinet via a wire, and the upper branch plug is connected to the branch plug on the upper branch transfer cabinet via a wire.

[0006] By adopting the above technical solution, when the power line on one of the floors needs to be replaced or repaired, firstly, the main power strip and the main plug on the side closest to the branch switch are disconnected. Then, the branch power strip on that floor is connected to the branch plug at the bottom of that floor. Subsequently, the branch power strip on the lower floor is connected to the branch plug on the upper side of that floor. At this time, the power signal from the lower floor will be transmitted from the branch power strip and branch plug on the lower floor to the branch power strip and branch plug on the repair floor through the wire, and then transmitted to the main power strip and main plug on the user side through the wire, so as to ensure the normal use of low-voltage electricity on the repair floor.

[0007] Furthermore, the mounting housing is provided with a displacement assembly, which includes a mounting box rotatably mounted inside the mounting housing. The mounting box has a through sliding hole. The displacement assembly also includes a fixing plate fixed to the mounting box, a displacement screw threaded through the fixing plate and connected by threads, and a sliding connecting plate slidably mounted through the mounting box. One end of the sliding connecting plate is fixed to the support plug, and the other end of the sliding connecting plate passes through the through sliding hole and is slidably engaged. The displacement screw is rotatably mounted on the sliding connecting plate.

[0008] By adopting the above technical solution, the mounting box is rotated 180 degrees. At this time, the support plug moves from the top of the mounting box to the bottom of the mounting box. The displacement screw is rotated. Since the displacement screw is threadedly connected to the fixed plate, the displacement screw is rotatably connected to the sliding connecting plate, thereby driving the support plug to move downward until the support plug is plugged into the lower support plug to ensure normal power supply.

[0009] Furthermore, the mounting box is provided with a distance adjustment mechanism, which includes a connecting component. The connecting component includes a connecting plate that is disposed through the mounting box and slidably engaged with it, and an adjusting column disposed on the connecting plate. The connecting plate is fixedly connected to the main power strip. The number of the connecting components is equal to the number of the main power strips and their positions correspond one-to-one. The distance adjustment mechanism also includes a distance adjustment component for adjusting the distance between the two adjusting columns.

[0010] By adopting the above technical solution, firstly, the distance adjustment component is operated to reduce the distance between the two adjustment columns, and then the distance between the two connecting plates is adjusted until the two main sockets are separated from the two main plugs. The mounting box is rotated until the branch socket is in position with the main plug near the user. Then, the displacement component is operated to insert the branch socket into the main plug near the user. Subsequently, the distance adjustment component is operated to increase the distance between the two adjustment columns until the two main sockets are connected to the branch plugs on the upper and lower sides respectively. At this time, part of the current flows from the main plug to the user, and the other part of the current is transmitted to the upper or lower floor through the wire between the two main plugs, thereby achieving the purpose of temporarily supplying power to the two floors.

[0011] Furthermore, the adjusting assembly includes an adjusting disc rotatably mounted inside the mounting box, a connecting rod that passes through the mounting box and is rotatably connected, and a knob fixedly sleeved on the connecting rod. The connecting rod is fixed to the adjusting disc and coaxially arranged. The adjusting disc has an adjusting through hole that slides with the adjusting column. The adjusting through hole is eccentrically arranged with the adjusting disc. The number of adjusting through holes is equal to the number of adjusting columns and their positions correspond one-to-one.

[0012] By adopting the above technical solution, rotating the knob drives the connecting rod to rotate, which in turn drives the adjustment plate fixed to the connecting rod to rotate synchronously. Since the adjustment through hole and the adjustment plate are eccentrically set, the adjustment through hole and the adjustment column slide together, thereby achieving the purpose of the two adjustment columns moving closer or further apart. There is no need to operate the two main plugs and their corresponding main plugs or branch plugs to plug or disconnect them separately, which facilitates the use of the device.

[0013] Furthermore, the mounting box is provided with a limiting component, which includes a fixing block fixed to the mounting box and a limiting screw threaded through and threaded onto the fixing block. The side wall of the mounting shell is provided with a limiting groove for the limiting screw to be inserted. Multiple limiting grooves are provided and distributed in a rectangular array.

[0014] By adopting the above technical solution, the limiting screw is rotated until it separates from the connected limiting groove, then the mounting box is rotated to the desired rotation angle, and then the limiting screw is rotated in the opposite direction until it is inserted into the corresponding limiting groove, thereby limiting the mounting box and improving the stability of the mounting box in a static state.

[0015] Furthermore, the limiting component also includes an auxiliary block fixed to the limiting screw and coaxially arranged with the limiting screw.

[0016] By adopting the above technical solution, the auxiliary block facilitates the rotation of the limiting screw.

[0017] Furthermore, the adjusting column passes through the connecting plate and is rotatably connected.

[0018] By adopting the above technical solution, the adjusting column and the connecting plate are rotatably connected, which reduces the friction between the adjusting column and the adjusting through hole when the adjusting column moves.

[0019] Furthermore, multiple anti-slip strips are fixed on the side walls of both the auxiliary block and the knob.

[0020] By adopting the above technical solution, the probability of slippage when rotating the auxiliary block and the knob is reduced.

[0021] In summary, this utility model has the following beneficial effects: In this application, by improving the existing structure and supplying power from other floors, normal circuit use is ensured when the maintenance floor is being inspected or the power line is being replaced, thus avoiding unnecessary trouble for customers.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-6As shown in the illustration, this application discloses a low-voltage distribution structure for building floors, including a main switch 1, a relay cabinet 2, branch switches 3, a displacement component 9, an adjustment mechanism 11, and a limiting component 13. Multiple relay cabinets 2 are provided, each located on a different floor. Branch switches 3 are fixed within the relay cabinet 2 and connected to the main switch 1 via wires. A mounting shell 4 is fixed inside the relay cabinet 2, and two main power strips 5 are slidably disposed within the mounting shell 4. The two main power strips 5 are electrically connected via wires. Main plugs 6, fixed to the mounting shell 4, are disposed through the side walls on both sides of the mounting shell 4. One main plug 6 is electrically connected to the branch switch 3 via a wire, and the other main plug 6 is electrically connected to the user's product via a wire. The main plugs 6 are plugged into the corresponding main power strips 5. Branch power strips 7 are disposed inside the mounting shell 4. The branch power strips 7 are electrically connected to the two main power strips 5 via wires. Branch plugs 8, fixed to the mounting shell 4, are disposed through the top and bottom of the mounting shell 4. The lower branch plug 8 is connected to the branch plug 8 on the lower branch transfer cabinet 2 via a wire, and the upper branch plug 8 is connected to the branch plug 8 on the upper branch and transfer cabinet 2 via a wire. When the power line on one of the floors needs to be replaced or repaired, first disconnect the main socket 5 and the main plug 6 near the branch exchange 3. Then, connect the branch socket 7 of that floor to the branch plug 8 at the bottom of that floor. Subsequently, connect the branch socket 7 of the lower floor to the branch plug 8 at the top of that floor. At this time, the power signal of the lower floor will be transmitted from the branch socket 7 and branch plug 8 of the lower floor to the branch socket 7 and branch plug 8 of the repair floor via a wire, and then transmitted to the main socket 5 and main plug 6 on the user side via a wire, so as to ensure the normal use of low-voltage electricity on the repair floor.

[0026] The displacement assembly 9 is mounted on the mounting housing 4. The displacement assembly 9 includes a mounting box 91, a fixing plate 92, a displacement screw 93, and a sliding connecting plate 94. The mounting box 91 is rotatably mounted inside the mounting housing 4, and a sliding through hole 10 is provided through the mounting box 91. The fixing plate 92 is fixed to the mounting box 91, and the displacement screw 93 is threaded through the fixing plate 92. The sliding connecting plate 94 is slidably mounted through the mounting box 91, with one end fixed to the support strip 7. The other end of the sliding connecting plate 94 passes through the sliding through hole 10 and is slidably engaged. The displacement screw 93 is rotatably mounted on the sliding connecting plate 94. Rotate the mounting box 91 180 degrees. At this time, the support plug 7 moves from the top of the mounting box 91 to the bottom of the mounting box 91. Rotate the displacement screw 93. Since the displacement screw 93 is threadedly connected to the fixing plate 92, the displacement screw 93 is rotatably connected to the sliding connecting plate 94, thereby driving the support plug 7 to move downward until the support plug 7 is plugged into the lower support plug 8 to ensure normal power supply.

[0027] An adjustment mechanism 11 is mounted on the mounting box 91. The adjustment mechanism 11 includes a connecting component 111 and an adjustment component 112. The connecting component 111 includes a connecting plate 1111 and an adjusting post 1112. The connecting plate 1111 is disposed through the mounting box 91 and slidably engaged. The connecting plate 1111 is fixedly connected to the main socket 5. The number of connecting plates 1111 is equal to the number of main sockets 5 and their positions correspond one-to-one. The adjusting post 1112 is disposed on the connecting plate 1111. First, operate the distance adjustment component 112 to reduce the distance between the two adjustment columns 1112, and then adjust the distance between the two connecting plates 1111 until the two main sockets 5 are separated from the two main plugs 6. Rotate the mounting box 91 until the branch socket 7 is in the position of the main plug 6 near the user. Then, operate the displacement component 9 to insert the branch socket 7 into the main plug 6 near the user. Then, operate the distance adjustment component 112 to increase the distance between the two adjustment columns 1112 until the two main sockets 5 are connected to the branch plugs 8 on the upper and lower sides respectively. At this time, part of the current flows from the main plug 6 to the user, and the other part of the current is transmitted to the upper or lower floor through the wire between the two main plugs 6, thereby achieving the purpose of temporarily supplying power to the two floors.

[0028] The adjusting assembly 112 is used to adjust the distance between the two adjusting columns 1112. The adjusting assembly 112 includes an adjusting plate 1121, a connecting rod 1122, and a knob 1123. The adjusting plate 1121 is rotatably mounted in the mounting box 91, and the connecting rod 1122 passes through the mounting box 91 and is rotatably connected. The connecting rod 1122 is fixed and coaxially arranged with the adjusting plate 1121. The adjusting plate 1121 has adjusting through holes 12 that slide with the adjusting columns 1112. The adjusting through holes 12 are eccentrically arranged with the adjusting plate 1121. The number of adjusting through holes 12 is equal to the number of adjusting columns 1112, and their positions correspond one-to-one. The knob 1123 is fixedly sleeved on the connecting rod 1122. Rotating the knob 1123 drives the connecting rod 1122 to rotate, which in turn drives the adjusting plate 1121, which is fixed to the connecting rod 1122, to rotate synchronously. Since the adjusting through hole 12 and the adjusting plate 1121 are eccentrically set, the adjusting through hole 12 and the adjusting column 1112 slide together, thereby achieving the purpose of the two adjusting columns 1112 moving closer or further apart. There is no need to operate the two main plugs 5 to connect or disconnect the corresponding main plugs 6 or branch plugs 8 separately, which facilitates the use of the device.

[0029] A limiting component 13 is disposed on the mounting box 91. The limiting component 13 includes a fixing block 131 and a limiting screw 132. The fixing block 131 is fixed to the mounting box 91, and the limiting screw 132 passes through the fixing block 131 and is threadedly connected. A limiting groove 14 is provided on the side wall of the mounting shell 4 for the limiting screw 132 to enter and insert. Multiple limiting grooves 14 are provided and distributed in a rectangular array. The limiting screw 132 is rotated until it separates from the connected limiting groove 14. Then, the mounting box 91 is rotated to the desired rotation angle. Subsequently, the limiting screw 132 is rotated in the opposite direction until it is inserted into the corresponding limiting groove 14, thereby limiting the mounting box 91 and improving the stability of the mounting box 91 in a stationary state.

[0030] The limiting assembly 13 also includes an auxiliary block 133, which is fixed to the limiting screw 132 and coaxially arranged with the limiting screw 132. The auxiliary block 133 facilitates the rotation of the limiting screw 132.

[0031] The adjusting column 1112 passes through the connecting plate 1111 and is rotatably connected. The rotatable connection between the adjusting column 1112 and the connecting plate 1111 reduces the friction between the adjusting column 1112 and the adjusting through hole 12 when the adjusting column 1112 moves.

[0032] Multiple anti-slip strips are fixed on the side walls of both the auxiliary block 133 and the knob 1123. This reduces the probability of slippage when rotating the auxiliary block 133 and the knob 1123.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
