DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figure 1-3 The waterproof car top junction box for elevators shown in the figure includes a box body 1, a base 2, a door panel 3, a base cover 4, a buckle 5, a fixing bracket 6, a plug wire fixing plate 7, a cable fixing bracket 8, an isolation column 9 and a pressure plate 10, and the whole is a narrow and long upper and lower chamber structure; the door panel 3 is arranged on one side of the box body 1, and the two sides of the door panel 3 are detachably connected to the box body 1 through the buckle 5, and the box body 1 and the door panel 3 together form a closed upper chamber; the upper chamber is the device installation body, and is the functional configuration realization chamber of the car top junction box; the fixing bracket 6 is arranged on the back wall of the box body 1 relative to the door panel 3, and the fixing bracket The frame 6 is used to fix the car top junction box to the car upper beam or fence; the base 2 is arranged below the box body 1, and a wire outlet hole 11 is provided at the connection between the base 2 and the bottom surface of the box body 1. The wire outlet hole 11 is a long waist hole structure. One side of the base 2 is connected to a base cover plate 4 by screws. The base 2, the base cover plate 4 and the bottom surface of the box body 1 together form a lower chamber with five sides of enclosure. The lower chamber is an incoming line chamber type, which plays a role in connecting and protecting the internal devices and wiring in the upper chamber. The bottom surface of the base 2 is a hollow structure, and the cable enters from the bottom of the base 2 and extends into the box body 1 through the outlet hole; see Figure 4 A wire fixing plate 7 and a cable fixing bracket 8 are fixedly provided in the box body 1. The cable fixing bracket 8 is arranged below the wire fixing plate 7. The pressing plate 10 and the cable fixing bracket 8 are separated by an isolation column 9. The screws pass through the pressing plate 10 and the isolation column 9 to fix the pressing plate 10 on the cable fixing bracket 8. The space formed between the pressing plate 10 and the cable fixing bracket 8 is used to constrain and fix the cables extending into the box body 1.

[0025] In this embodiment, see Figure 5The buckle 5 includes a buckle fixing frame 51, a buckle flap 52 and a fixing buckle 53; the buckle fixing frame 51 is installed on the box body 1, and the fixing buckle 53 is installed on the door panel 3. The fixing buckle 53 is on the same side as the buckle fixing frame 51. The buckle flap 52 is hinged to the buckle fixing frame 51. When the buckle flap 52 rotates relative to the fixing frame 51, the end of the buckle flap 52 moves in a direction close to or away from the fixing buckle 53 to achieve locking or disassembly of the door panel. After the buckle is clamped, the box body and the door panel form a basically closed cavity.

[0026] In this embodiment, a sealing strip 12 is provided at the connection between the door panel 3 and the box body 1. A circle of sealing strips is pasted around the door panel, and after the buckle is clamped, the box body and the door assembly form a basically closed cavity.

[0027] In this embodiment, rubber washers are provided at the connection between the box body 1 and the buckle fixing frame 51 and at the connection between the door panel 3 and the fixing buckle 53. The connection between the two sides of the box body and the outer side of the door panel uses stainless steel screws through rubber washers. After tightening the screws, the screw openings will be compacted and sealed to ensure that water cannot penetrate from the buckle installation holes.

[0028] In this embodiment, see Figure 6 The car roof junction box plate is a textured stainless steel plate, and the plates in the upper chamber of the box body are fully welded. The back wall of the box body 1 relative to the door panel 3 is a double-layer plate structure, including an outer plate 101 and an inner plate 102; the outer plate 101 is located on the outer layer of the box body 1, and is used to fix the fixing bracket 6, and the inner plate 102 is located inside the box body 1, and is used to fix the plug-in fixing plate 7 and the cable fixing bracket 8. Except for the outlet hole reserved on the bottom surface of the upper chamber of the box body, the openings in other parts are compacted and sealed using waterproof devices, waterproof joints, and stainless steel screws with rubber gaskets to ensure that external water cannot enter the upper chamber of the box body from all directions.

[0029] In this embodiment, see Figure 7 The fixing bracket 6 is an L-shaped bracket, and a long hole 61 is opened on the long side of the L-shaped bracket; a screw is arranged in the long hole 61, and the long hole 61 is connected to the outer plate 101 by the screw. During installation, the fixing position of the long hole can be adjusted according to the gap between the bottom of the car top junction box and the car top wire duct.

[0030] In this embodiment, the cable fixing bracket 8 is provided with two groups, namely a cable fixing high bracket 81 and a cable fixing low bracket 82; the wire fixing plate 7 is fixedly connected to the inner plate 102 by 4 screws, and the plug-in fixing plate is used to install the plug-ins and sockets inside the junction box; the cable fixing high bracket 81 and the cable fixing low bracket 82 are arranged in sequence below the wire fixing plate 7, and are fixedly connected to the inner plate 102 by 4 screws respectively.

[0031] The specific operation process of the present invention is as follows:

[0032] The width of the car top junction box is controlled within 380mm, the thickness is within 150mm, the top operating height is 800mm, and the height of the base 2 is 100mm. When installing the car top junction box, adjust the gap between the bottom surface of the box base 2 and the metal wire trough on the car top through the fixing bracket 6. When wiring or repairing, open the buckle 5 in turn, move down the door panel 3; loosen the base cover screws, and remove the base cover 4. When threading, pass the cable in the metal wire trough on the car top through the lower cavity of the base and enter the upper cavity of the box 1. After the upper cavity plug-in and terminal wiring are completed, the cables in the upper cavity are neatly arranged and pressed by the cable fixing bracket 8 and the pressing plate 10. The excess length of the cable can be folded into the bottom cavity and a certain telescopic length is reserved to avoid the cross-entanglement of the cables at the terminals and plug-ins, reduce the difficulty of repair and line checking, and also ensure that the wiring of the upper cavity is clearly layered and beautifully arranged.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
