Description

Technical Field

[0001] This application relates to the field of line protection technology, specifically a protection device for incoming lines to a low-voltage electrical room. Background Technology

[0002] Low-voltage circuits generally refer to DC circuits or audio, video, network, and telephone lines. DC voltage is typically below 36 volts. Household appliances such as telephones, computers, televisions' cable signal input lines, and audio equipment's output lines are all examples of low-voltage electrical equipment. Conceptually, high-voltage and low-voltage circuits are generally easy to distinguish; the main difference lies in their purpose. High-voltage electricity is used as a power source, while low-voltage electricity is used as a signal source. Voltage is not the sole distinguishing factor. During installation, these low-voltage circuits require protection. However, most current incoming line protection devices fail to properly clamp and secure the wiring, leading to messy internal wiring.

[0003] Chinese utility model patent CN220382657U discloses an intelligent low-voltage incoming line protection device for communication equipment room renovation. It places the low-voltage line on a semi-circular ball seat. Rotating the operating handle drives the screw to move, causing the semi-circular receiving plate and semi-circular mounting base to move downwards. The semi-circular mounting base then moves a spring and a limiting plate closer to and until they fully contact the low-voltage line, securing it in place. This provides stronger support for the bottom wall of the line during the limiting and fixing process, while also protecting the top of the line, thus enhancing the safety of the low-voltage line. However, installing or removing the line from the semi-circular ball seat usually requires opening the upper fixing base or pulling the line out from one end. Pulling out the line is inconvenient when it is too long, and opening the upper fixing base is also necessary for maintenance of a specific section of the line, making the operation inconvenient.

[0004] Therefore, this application provides a protection device for incoming lines to a low-voltage electrical room to solve the above problems. Utility Model Content

[0005] This application provides a low-voltage electrical room incoming line protection device, which aims to solve the problems mentioned in the background art. When installing or removing the line into the hemispherical base, the existing low-voltage incoming line protection device usually requires opening the upper fixing base or pulling the line out from one end. When the line is too long, it is inconvenient to pull it out. When maintaining a part of the line, it is also necessary to open the upper fixing base, which is inconvenient to operate.

[0006] To achieve the above objectives, this application provides the following technical solution: a low-voltage electrical room incoming line protection device, comprising a mounting plate, a mounting base fixedly mounted on the mounting plate, and a cable management mechanism slidably mounted on the mounting base for organizing cable harnesses.

[0007] The combing mechanism includes a base slidably mounted on a mounting seat. The base has a insertion cavity, into which several U-shaped wire clamping frames, evenly arranged from top to bottom, are inserted. Each wire clamping frame has a clearance groove at one end facing the insertion cavity. Thus, during wiring installation, the mounting plate is fixed to the mounting surface, and the wire clamping frames are pulled outwards to expose the clearance grooves. The wire harness is then inserted into the wire clamping frames through the clearance grooves. The wire clamping frames are then pushed further into the insertion cavity. The adjacent upper wire clamping frames block the clearance grooves at the top of the lower wire clamping frames from behind, ensuring the wire harness is stably installed within the wire clamping frames. Installing or removing the wiring only requires pulling the wire clamping frames. Compared to existing fixed clamps, no disassembly device is needed, making operation very convenient.

[0008] Preferably, to prevent detachment, a sliding groove is provided inside the insertion cavity, and a slider that matches the sliding groove and is slidably connected within the sliding groove is fixedly installed on the wire clamping frame. This ensures stable movement of the wire clamping frame, prevents the wire clamping frame from detaching from the base, and ensures stability and reliability.

[0009] Preferably, for automatic reset, a guide rod is fixedly installed inside the slide groove, the slider is sleeved on the guide rod, and a spring is sleeved on the guide rod. This allows the wire clamp frame to automatically reset into the insertion cavity, making it convenient to use.

[0010] Preferably, mounting holes are provided near the four corners of the mounting plate to secure it. This makes operation convenient and quick.

[0011] Preferably, to adjust the height difference, the protective device further includes a lifting mechanism. The lifting mechanism includes a lifting cavity formed on the mounting base, a lead screw rotatably mounted within the lifting cavity, and a lifting block adapted to the lifting cavity screwed onto the lead screw. The outer wall of the lifting block is fixedly connected to the outer wall of the base. Changing the height difference of each section of the line ensures that the line is installed horizontally as much as possible, avoiding bending of the wire harness that could affect transmission.

[0012] Preferably, for ease of adjustment, one end of the lead screw passes through the lifting cavity and extends outside the mounting base, and a knob is fixedly installed at the end of the lead screw located outside the mounting base. This allows for convenient and quick adjustment of the lifting block's position.

[0013] This protective device fixes the mounting plate to the mounting surface, pulls the wire clamp frame outward to expose the relief groove, inserts the wire harness into the wire clamp frame through the relief groove, and then pushes the wire clamp frame into the plug cavity. The adjacent upper wire clamp frame blocks the relief groove at the top of the lower wire clamp frame through its bottom, thus ensuring that the wire harness is stably installed in the wire clamp frame, organizing and protecting the wire harness. When installing or removing the line, simply pull the wire clamp frame. Compared with existing fixed clamps, there is no need to disassemble the device, making the operation very convenient.

[0014] After the mounting plate is fixed on the plane, the screw is rotated, which drives the lifting block to rotate. The lifting block is restricted and moves up and down in the lifting cavity, thereby driving the base fixedly connected to the lifting block to adjust up and down on the mounting seat. This changes the height difference of each section of the line, ensuring that the line is installed horizontally as much as possible and avoiding bending of the wire harness from affecting transmission.

[0021] The technical solutions of 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a protection device for the incoming line of a low-voltage electrical room, such as... Figure 1-4 As shown, the protective device includes a mounting plate 1, a mounting base 2 fixedly mounted on the mounting plate 1, and a combing mechanism 3 slidably mounted on the mounting base 2 for organizing the wire harness.

[0024] The combing mechanism 3 includes a base 31 that is slidably mounted on the mounting base 2. The base 31 has an insertion cavity 32. Several U-shaped wire clamping frames 33 are inserted into the insertion cavity 32 and are evenly arranged from top to bottom. The wire clamping frames 33 have a clearance groove 34 at one end facing the insertion cavity 32.

[0025] In use, the mounting plate 1 is fixed on the mounting surface, and the wire clamping frame 33 is pulled outward to expose the relief groove 34. The wire harness is inserted into the wire clamping frame 33 through the relief groove 34, and then the wire clamping frame 33 is pushed into the plug cavity 32. The adjacent upper wire clamping frame 33 blocks the relief groove 34 at the top of the lower wire clamping frame 33 through its bottom, so that the wire harness is stably installed in the wire clamping frame 33, which organizes and protects the wire harness. When installing or removing the line, you only need to pull the wire clamping frame 33. Compared with the existing fixed clamps, there is no need for disassembly, and the operation is very convenient.

[0026] Specifically, a groove 35 is provided inside the insertion cavity 32, and a slider 36 that is adapted to the groove 35 and slidably connected within the groove 35 is fixedly installed on the wire clamping frame 33. In use, when the wire clamping frame 33 is pulled, the slider 36 slides within the groove 35, defining the movement trajectory of the wire clamping frame 33, ensuring stable movement of the wire clamping frame 33, preventing the wire clamping frame 33 from detaching from the base 31, and ensuring stability and reliability.

[0027] More specifically, a guide rod 37 is fixedly installed inside the slide groove 35, and a slider 36 is sleeved on the guide rod 37. A spring 38 is sleeved on the guide rod 37. In use, when the wire clamping frame 33 is pulled outward, the slider 36 compresses the spring 38, causing the spring 38 to contract under pressure. After the wire harness is installed or removed, the wire clamping frame 33 is released, and the spring 38 rebounds the slider 36 through its elastic force, causing the wire clamping frame 33 to automatically return to its original position and enter the insertion cavity 32, making it convenient to use.

[0028] Furthermore, mounting holes 11 are provided near the four corners of the mounting plate 1. In use, the mounting plate 1 is placed flat on the mounting surface, and the mounting plate 1 is fixed to the mounting surface by bolts passing through the mounting holes 11, making the operation convenient and quick.

[0029] Example 2

[0030] Unlike Embodiment 1, the installation space may be limited during the installation of the lines at various locations, potentially resulting in significant height differences and requiring adjustments. Therefore, this protective device also includes a lifting mechanism 4. The lifting mechanism 4 comprises a lifting cavity 41 formed on the mounting base 2. A lead screw 42 is rotatably mounted within the lifting cavity 41, and a lifting block 44, adapted to the lifting cavity 41, is screwed onto the lead screw 42. The outer wall of the lifting block 44 is fixedly connected to the outer wall of the base 31. After fixing the mounting plate 1 to the plane, rotating the lead screw 42 causes the lifting block 44 to rotate. The lifting block 44, constrained, moves up and down within the lifting cavity 41, thereby causing the base 31, fixedly connected to the lifting block 44, to move up and down on the mounting base 2. This changes the height difference of each line segment, ensuring the lines are installed horizontally as much as possible and preventing bending of the wire harness from affecting transmission.

[0031] Specifically, one end of the lead screw 42 passes through the lifting cavity 41 and extends outside the mounting base 2. A knob 43 is fixedly installed at the end of the lead screw 42 located outside the mounting base 2. In use, the position of the lifting block 44 is adjusted by rotating the knob 43 to drive the lead screw 42 to rotate. This is convenient and quick.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
