Description

Technical Field

[0001] The present invention relates to the technical field of junction boxes, and particularly to an upper structure junction box installation device. Background Art

[0002] In ship production design, multiple factors need to be comprehensively considered for the installation position of the upper structure junction box. Generally speaking, the junction box should be set in a place convenient for wiring, maintenance and not affecting equipment operation, and comply with relevant electrical installation specifications and standards.

[0003] Currently, when installing the junction box, in addition to meeting the above conditions, installing the junction box inside the ceiling at the top of the living area walkway can eliminate the need for equipment pedestals, reduce the number of steel outfitting parts and welding work. However, the actual effect is not very ideal. The junction box is fixed inside the ceiling. After the ceiling is installed, a lot of inspection doors need to be opened, which not only increases the on-site construction volume but also increases the cost of materials and physical quantities. The position of the existing junction box is generally fixed after installation, and the height cannot be effectively adjusted as needed, making maintenance inconvenient. Moreover, the cables connected to the junction box cannot be fixed, and the redundant cables cannot be stored, easily causing cable chaos. Therefore, an upper structure junction box installation device is needed to solve the above problems. Summary of the Invention

The upper end of the adjustment screw rod is rotatably connected to the mounting plate. The lower end of the adjustment screw rod passes through the bottom connecting plate and is connected to the knob.

[0010] Preferably, fixing wire assemblies are provided at the middle ends of the two vertical angle steels. The fixing wire assembly includes an L-shaped frame, a limiting sliding rod and a pressing block. The horizontal plate of the L-shaped frame is connected to the vertical angle steel. A sliding hole is opened on the vertical plate of the L-shaped frame. One end of the limiting sliding rod is connected to the pressing block. The end of the limiting sliding rod far from the pressing block passes through the sliding hole and is provided with a handle.

[0011] Preferably, a compression spring is sleeved on the outer surface of the limiting sliding rod. Annular gaskets are provided at both ends of the compression spring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The superstructure junction box installation device is provided with a height adjustment component. The upper end of the limit vertical rod passes through the perforation formed in the second horizontal angle steel and is slidably connected to the second horizontal angle steel, which can effectively limit the installation plate, ensuring that the installation plate moves up and down in the vertical direction. By rotating the knob, the adjustment screw can be effectively driven to rotate. During the upward rotation of the adjustment screw and under the limiting effect of the limit vertical rod, the installation plate can be effectively lifted. During the downward rotation of the adjustment screw and under the limiting effect of the limit vertical rod, the installation plate can be effectively driven to descend, realizing the effective adjustment of the height of the installation plate and the signal equipment box and low-voltage equipment box installed thereon. When there is no need for maintenance, the installation plate is adjusted to a high position to avoid being damaged by collision. When maintenance is required, the installation plate is lowered to a suitable height to facilitate maintenance operations by maintenance personnel of different heights.

[0018] 2. The superstructure junction box installation device uses a support frame to arrange the junction box behind the sanitary unit and shares the inspection door for maintenance with the sanitary unit. This can avoid opening an inspection door at the top, facilitating installation, convenient for maintenance, integrated installation, with good concealment, improving the beauty and integrity of the interior wall; in the subsequent electrical processes of the project, unified installation regulations are formed for the equipment on the superstructure that requires an inspection door, avoiding excessive installation forms and increasing the number of inspection doors.

[0019] 3. The superstructure junction box installation device is provided with a wire fixing component. By pulling the handle outwards, the limit slide rod moves synchronously. During the movement of the limit slide rod, the pressing block is driven to squeeze the compression spring and move towards the vertical plate of the L-shaped frame. At this time, it is convenient to place the cable between the pressing block and the vertical plate of the vertical angle steel. Then, release the handle, and the compression spring releases energy, effectively pushing the pressing block to move. The pressing block can cooperate with the vertical angle steel to clamp the cable, ensuring the stability of the cable; by setting a wire winding component, when the length of the signal cable or low-voltage cable is long, the excess cable can be wound around the outer surface of the winding column. Then, by tightening the fixing screw, the strip-shaped anti-disengagement plate is fixed at the front end of the winding column, which can effectively limit the cable and prevent the cable from detaching from the winding column, ensuring the neatness of the cable; the strip-shaped anti-disengagement plate is convenient for installation and disassembly. After disassembling the strip-shaped anti-disengagement plate, the cable wound around the winding column can be removed, facilitating the effective adjustment of the height of the signal equipment box and the low-voltage equipment box in cooperation with the height adjustment component.

The strip anti-slip plate 803 is detachable. When the signal cable 90 1 or when the length of the low-voltage cable 1001 is long, the excess cable can be wound around the outer surface of the winding post 802, and then the strip anti-slip plate 803 can be fixed to the front end of the winding post 802 by tightening the fixing screws 804, which can effectively limit the cable and prevent the cable from detaching from the winding post 802, thereby ensuring the neatness of the cable; the strip anti-slip plate 803 is easy to install and disassemble. After removing the strip anti-slip plate 803, the cable wound on the winding post 802 can be removed, which is convenient for cooperating with the height adjustment component 6 to effectively adjust the height of the signal equipment box 9 and the low-voltage equipment box 10.

[0037] Among them, avoidance grooves are provided at both ends of the first horizontal angle steel 303 and the second horizontal angle steel 304.

Then, release the handle 705, and the compression spring 704 releases energy, which can effectively push the pressing block 703 to move. The pressing block 703 can cooperate with the vertical angle steel 301 to clamp the cable and ensure the stability of the cable. When the length of the signal cable 901 or the low-voltage cable 1001 is relatively long, the redundant cable can be wound around the outer surface of the winding column 802. Then, by tightening the fixing screw 804, the strip-shaped anti-detachment plate 803 can be fixed at the front end of the winding column 802, which can effectively limit the cable and prevent the cable from detaching from the winding column 802, ensuring the neatness of the cable. The strip-shaped anti-detachment plate 803 is convenient for installation and disassembly. After disassembling the strip-shaped anti-detachment plate 803, the cable wound around the winding column 802 can be removed, which is convenient for effectively adjusting the heights of the signal device box 9 and the low-voltage device box 10 in cooperation with the height adjustment assembly 6.

[0040] Furthermore, by setting the limit vertical rod 501, the upper end of the limit vertical rod 501 passes through the perforation formed in the second horizontal angle steel 304 and is slidably connected to the second horizontal angle steel 304, which can effectively limit the mounting plate 5 and ensure the up and down movement of the mounting plate 5 in the vertical direction. By rotating the knob 603, the adjusting screw 602 can be effectively driven to rotate.
