Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a safe junction box for broadcasting and television engineering. Background Technology

[0002] In home broadcasting and television installation projects, junction boxes are often used to gather multiple incoming lines before they are routed out in batches. Therefore, various cables are concentrated inside the junction box. When gathering the incoming lines, to prevent excessive cable length and resulting clutter, any excess cable length needs to be left inside the junction box. When gathering a large number of cables, the junction box must prevent the cables from becoming tangled together.

[0003] CN202320880685.8 describes a junction box for broadcasting and television engineering. It involves inserting one end of a cable into a take-up groove through an inlet, then winding the excess cable around the surface of a winding drum, and finally allowing the bottom end of the cable to exit through an outlet to the outside of the box. This facilitates the neat winding and tidying of excess cable from multiple cables. When the external cable is pulled, it causes a support plate to descend, compressing a spring to cushion the pulling force. The descent of the support plate also presses a trigger button, activating an alarm to alert the operator. However, this junction box has a low safety profile because it is difficult to extinguish a fire caused by a fault in the internal wiring, as the internal wiring is easily burned. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a safe junction box for broadcasting and television engineering, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a safe junction box for broadcasting and television engineering, comprising a junction box body, an elastic cable winding assembly disposed inside the junction box body, broadcasting and television engineering cables passing through the elastic cable winding assembly, a plurality of insulating heat insulation boards fixedly connected to the middle of the junction box body, a closed cover fixedly installed on the top of the insulating heat insulation boards and the junction box body, and a plurality of plastic fire extinguishing bags fixedly installed at the bottom of the closed cover, the plastic fire extinguishing bags being filled with fire extinguishing sand, and an elastic cable clamping block being attached to the bottom of the fire extinguishing bags.

[0006] Preferably, in any of the above embodiments, the main body of the junction box has a plurality of wire grooves inside, and wire holes are provided at both ends of the wire grooves. The wire grooves and the insulation plate are distributed alternately.

[0007] The above technical solution involves passing the broadcast television engineering cable through the wire hole at one end into the wire trough, then through the wire trough and through the wire hole at the other end, so that the broadcast television engineering cable runs through the entire junction box.

[0008] Preferably, in any of the above embodiments, the elastic take-up assembly includes a support spring and a take-up seat. The support spring is fixedly installed inside both the main body of the cable box and the insulating heat insulation plate. One end of the support spring is fixedly installed with a take-up seat that is movably connected to the main body of the cable box. The take-up seat is located inside the wire groove, and a take-up groove is formed in the middle of the take-up seat.

[0009] The above technical solution involves allowing the broadcast television engineering cable passing through the conductor trough to enter the inside of the take-up trough. The elasticity of the support spring is used to support the take-up seat, and adjacent take-up seats are distributed crosswise. The crosswise distribution of the take-up seats bends the broadcast television engineering cable inside the take-up trough, thereby enabling the storage of a certain length of broadcast television engineering cable inside the conductor trough, which facilitates the adjustment of the length of the broadcast television engineering cable.

[0010] Preferably, in any of the above embodiments, both ends of the broadcast television engineering cable pass through conductor holes, and the broadcast television engineering cable passes through the take-up base located inside the take-up groove.

[0011] The above technical solution involves applying force to the broadcast television engineering cable, which causes the cable inside the take-up trough to press against the take-up seat, thereby compressing the take-up seat against the support spring. Adjusting the position of the take-up seat allows for the adjustment of the length of the broadcast television engineering cable.

[0012] Preferably, in any of the above embodiments, the closed cover covers the top of the junction box body, and the closed cover and the junction box body are fixedly installed by screws.

[0013] The above technical solution involves using a sealed cover to enclose the main body of the junction box, ensuring the overall airtightness of the junction box.

[0014] Preferably, in any of the above embodiments, the plastic fire extinguishing bag is located at the top of the inside of the wire channel, and the number of the plastic fire extinguishing bags is the same as the number of the guide channels.

[0015] The above technical solution involves using plastic fire extinguishing bags to store fire extinguishing sand. Due to the nature of the plastic fire extinguishing bags, they are easily damaged by fire. After the plastic fire extinguishing bags are damaged, the fire extinguishing sand inside falls into the guide channel under the action of gravity, covering the burning broadcast and television engineering cables and thus extinguishing the fire.

[0016] Preferably, in any of the above embodiments, the elastic wire clamping block includes a fixing spring and a wire clamping plate. The fixing spring is fixedly installed inside the wire take-up seat, the top of the fixing spring is fixedly installed with the wire clamping plate, and the bottom of the wire clamping plate has a wire clamping groove in the middle.

[0017] The above technical solution involves pulling the cable clamping plate during the cable insertion process to stretch and fix the spring. After the cable is inserted, the clamping plate is released so that the cable is secured by the spring, ensuring the stability of the cable.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. An insulation structure is installed inside the junction box to separate the internal wiring. A rapidly incinerating plastic storage bag is installed above the wiring to store fire extinguishing sand. In the event of a fire caused by a wiring fault, the plastic storage bag will burn quickly, and the fire extinguishing sand inside will cover the ignition point under gravity, extinguishing the fire in time and preventing the fire inside the junction box from spreading and damaging other wiring. This effectively improves the fire resistance of the junction box and isolates and protects the internal wiring, enhancing the safety of the junction box.

[0020] 2. An adjustable cable winding structure is installed inside the junction box to guide the cable winding, and an adjustable cable clamping structure is installed inside the cable winding structure to facilitate cable installation and adjust the cable length inside the junction box.

[0028] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0029] like Figure 1-4 As shown in the figure, a safe junction box for broadcasting and television engineering according to an embodiment of the present invention includes a junction box body 1, an elastic cable winding assembly 2 is provided inside the junction box body 1, a broadcasting and television engineering cable 3 passes through the elastic cable winding assembly 2, a plurality of insulating heat insulation boards 4 are fixedly connected to the middle of the junction box body 1, a closed box cover 5 fixedly installed on the top of the insulating heat insulation board 4 and the junction box body 1, and a plurality of plastic fire extinguishing bags 6 are fixedly installed at the bottom of the closed box cover 5, the plastic fire extinguishing bags 6 are filled with fire extinguishing sand 7, and an elastic cable clamping block 8 is attached to the bottom of the fire extinguishing bag 6.

[0030] Preferably, in any of the above schemes, the main body 1 of the junction box has a plurality of wire grooves 9 inside, and wire holes 10 are provided at both ends of the wire grooves 9. The wire grooves 9 and the insulating heat insulation plate 4 are distributed in a cross pattern.

[0031] The above technical solution is adopted: after the broadcast television engineering cable 3 passes through the wire hole 10 at one end and enters the wire groove 9, it passes through the wire groove 9 and passes through the wire hole 10 at the other end, so that the broadcast television engineering cable 3 runs through the entire junction box.

[0032] Preferably, in any of the above solutions, the elastic take-up assembly 2 includes a support spring 21 and a take-up seat 22. The support spring 21 is fixedly installed inside both the main body 1 of the cable box and the insulating heat insulation plate 4. One end of the support spring 21 is fixedly installed with a take-up seat 22 that is movably connected to the main body 1 of the cable box. The take-up seat 22 is located inside the wire groove 9, and a take-up groove 11 is provided in the middle of the take-up seat 22.

[0033] The above technical solution involves allowing the broadcast television engineering cable 3, which passes through the conductor trough 9, to enter the take-up trough 11. The elasticity of the support spring 21 supports the take-up seat 22, causing adjacent take-up seats 22 to be distributed crosswise. The crosswise distribution of the take-up seats 22 bends the broadcast television engineering cable 3 inside the take-up trough 11, thereby enabling the broadcast television engineering cable 3 to be stored to a certain length inside the conductor trough 9, which facilitates the adjustment of the length of the broadcast television engineering cable 3.

[0034] Preferably, both ends of the broadcast television engineering cable 3 pass through the conductor holes 10, and the broadcast television engineering cable 3 passes through the take-up base 22 located inside the take-up groove 11.

[0035] By adopting the above technical solution: by applying force to the broadcast television engineering cable 3, the broadcast television engineering cable 3 inside the take-up trough 11 can be squeezed against the take-up seat 22, causing the take-up seat 22 to squeeze the support spring 21, and adjusting the position of the take-up seat 22 can achieve the adjustment of the length of the broadcast television engineering cable 3.

[0036] Preferably, in any of the above solutions, the cover 5 covers the top of the junction box body 1, and the cover 5 and the junction box body 1 are fixedly installed by screws.

[0037] The above technical solution is adopted: the main body 1 of the junction box is covered and sealed by the sealing cover 5 to ensure the overall airtightness of the junction box.

[0038] Preferably, in any of the above embodiments, the plastic fire extinguishing bag 6 is located at the top of the wire channel 9, and the number of plastic fire extinguishing bags 6 is the same as the number of wire channels 9.

[0039] The above technical solution is adopted: a plastic fire extinguishing bag 6 is used to store fire extinguishing sand 7. Due to the material of the plastic fire extinguishing bag 6, it is easily damaged by fire. After the plastic fire extinguishing bag 6 is damaged, the fire extinguishing sand 7 inside it falls into the wire trough 9 under the action of gravity and covers the burning broadcast and television engineering cable 3, thereby playing a role in extinguishing the fire.

[0040] Preferably, in any of the above embodiments, the elastic wire clamping block 8 includes a fixing spring 81 and a wire clamping plate 82. The fixing spring 81 is fixedly installed inside the wire take-up base 22, and the wire clamping plate 82 is fixedly installed on the top of the fixing spring 81. A wire clamping groove is provided in the middle of the bottom end of the wire clamping plate 82.

[0041] The above technical solution is adopted as follows: during the process of the broadcast and television engineering cable 3 being inserted into the cable tray 11, the cable clamping plate 82 is pulled to stretch the fixing spring 81. After the broadcast and television engineering cable 3 is inserted, the cable clamping plate 82 is released so that the broadcast and television engineering cable 3 is locked in place under the action of the fixing spring 81, thereby ensuring the stability of the broadcast and television engineering cable 3.

[0042] The working principle of this utility model for a safe junction box used in broadcasting and television engineering is as follows:

[0043] The broadcast television engineering cable 3 is passed through the wire hole 10 and into the inside of the wire groove 9. The cable clamp 82 is pulled to pass the broadcast television engineering cable 3 into the inside of the cable take-up groove 11. After releasing the cable clamp 82, the sealing box cover 5 is fastened to the top of the junction box body 1 to seal the junction box.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] 1. An insulation structure is installed inside the junction box to separate the internal wiring. A rapidly incinerating plastic storage bag is installed above the wiring to store fire extinguishing sand 7.
