Description

Technical Field

[0001] The utility model relates to the technical field of fixed brackets, in particular to an explosion-proof junction box fixed bracket. Background Art

[0002] The explosion-proof junction box is a sealed box that prevents sparks generated by short circuits from affecting the wiring ports in dangerous areas on site. The explosion-proof junction box is made of cast metal and is used in explosion-proof areas. It is mainly used in houses and frame structures. It is used when cables change direction to avoid sparks inside the lines and create safety hazards to the surrounding environment.

[0003] During the installation process, a fixed bracket is required for the explosion-proof junction box. The bracket can provide stable support to ensure that the explosion-proof junction box will not shake or move after installation, thereby improving its stability. The bracket can ensure the isolation of the explosion-proof junction box from the surrounding environment and reduce safety hazards caused by external factors such as impact and vibration.

[0005] In the above-mentioned prior art, although the bracket installs the junction box in the installation cavity of the fixed bracket and uses the elastic force of the locking spring to press and fix the junction box, the bracket in the patented technology only limits and fixes the junction box by the elastic force of the spring, and the fixing method is not firm. The spring may become loose during the use process, which will reduce the fixing effect over time, and then cause the junction box installation to be not stable enough. Therefore, we need an explosion-proof junction box fixing bracket. Utility Model Content

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an explosion-proof junction box fixing bracket, comprising a fixing plate 1, a connecting plate 2 is installed on one side of the fixing plate 1, and a mounting component 3 is arranged on one side of the connecting plate 2, and a detachable component 7 is installed inside the fixing plate 1;

[0027] The mounting assembly 3 includes a motor 301, the output end of the motor 301 is detachably connected to a screw rod 302 through a coupling, and the outer surface of the screw rod 302 is rotatably connected to a lifting block 303, one side of the lifting block 303 is fixedly connected to a connecting frame 304, and one side of the connecting frame 304 is threadedly connected to a screw rod 305, one end of the screw rod 305 is rotatably connected to a limiting plate 306, and a first spring 307 is installed on the inner wall of the connecting frame 304, and one end of the first spring 307 is fixedly connected to a buffer plate 308;

[0028] The detachable component 7 includes a card slot 701, the inner wall of the card slot 701 is snap-connected with a card block 702, and a positioning slot 703 is opened on one side of the card block 702, the inner wall of the positioning slot 703 is snap-connected with a positioning rod 704, and one side of the positioning rod 704 is fixedly connected with a second spring 705, and the inner wall of the second spring 705 is sleeved with a pull rod 706.

[0029] Through the above technical scheme, by starting the motor 301, the two lifting blocks 303 can be driven to move up and down in the connecting plate 2. Because the threads on both sides of the screw rod 302 rotate in opposite directions, the two lifting blocks 303 can be lifted relatively, so that the two connecting frames 304 can move relative to each other to clamp and limit the junction box. Rotating the screw rod 305 can drive the limit plate 306 to move and limit the junction box again, thereby improving the limiting effect. The buffer plate 308 moves inward under the action of the first spring 307, achieving a buffering effect, thereby greatly improving the limiting effect of the fixed bracket on the junction box.

[0030] Specifically, one side of the fixing plate 1 is fixedly connected with the mounting plate 4 , and one side of the mounting plate 4 is provided with a mounting groove 5 , and the inner wall of the mounting groove 5 is threadedly connected with a mounting screw 6 .

[0031] Through the above technical solution, it is convenient for the mounting groove 5 provided on the mounting plate 4 to extend the mounting screw 6 into the interior and then connect with the wall surface, so that the fixing bracket is fixed on the wall surface.

[0032] Specifically, the motor 301 forms a lifting structure through the screw rod 302 and the lifting block 303, and the threads on both sides of the screw rod 302 are rotated in opposite directions, and the number of the lifting blocks 303 is two.

[0033] Through the above technical solution, it is convenient to start the motor 301 to drive the screw rod 302 to rotate and drive the lifting block 303 to lift and lower at the same time, because the threads on both sides of the screw rod 302 rotate in opposite directions, and the two lifting blocks 303 are symmetrically arranged at both ends of the screw rod 302, thereby making the two lifting blocks 303 move relative to each other.

[0034] Specifically, the connecting frame 304 forms a movable structure through the screw rod 305 and the limiting plate 306 , and the external thread of the screw rod 305 matches the internal thread of the connecting frame 304 .

[0035] Through the above technical solution, the two lifting blocks 303 can drive the two connecting frames 304 to move relative to each other, and can clamp and fix the upper and lower sides of the junction box. Turning the screw 305 by hand can drive the limit plate 306 to move, and then the two limit plates 306 clamp and fix one side of the junction box, further improving the fixing effect.

[0036] Specifically, the connecting frame 304 forms an elastic structure through the first spring 307 and the buffer plate 308, and the number of the first springs 307 is two.

[0037] Through the above technical solution, when the junction box is squeezed, the buffer plate 308 can be elastically moved by the first spring 307 to prevent the limiting plate 306 from exerting excessive pressure on the junction box and causing damage to the junction box.

[0038] Specifically, the fixing plate 1 forms a snap-fit ​​structure with the snap-fit ​​block 702 through the snap-fit ​​slot 701, and the shape and size of the snap-fit ​​slot 701 match the shape and size of the snap-fit ​​block 702. The snap-fit ​​block 702 forms a snap-fit ​​structure with the positioning rod 704 through the positioning slot 703, and the shape and size of the positioning slot 703 match the shape and size of the positioning rod 704.

[0039] Through the above technical solution, the connecting plate 2 can be conveniently extended into the slot 701 through the clamping block 702 to connect with the fixed plate 1, and the position of the clamping block 702 can be limited and fixed by extending the positioning rod 704 into the positioning slot 703, thereby achieving the effect of installing and fixing the connecting plate 2.

[0040] Specifically, the fixing plate 1 forms an elastic structure with the second spring 705 and the positioning rod 704 , and one end of the pull rod 706 penetrates the inner wall of the second spring 705 and is connected to the positioning rod 704 .

[0041] Through the above technical solution, it is convenient for the positioning rod 704 to extend into the positioning groove 703 through the elastic pressure of the second spring 705 to limit the block 702. Pulling the pull rod 706 can make the positioning rod 704 move outward to release the limitation on the block 702. At the same time, the second spring 705 is also compressed, thereby achieving the effect of quickly installing and disassembling the connecting plate 2.

[0042] Working principle: when using the explosion-proof junction box fixing bracket, first, when installing the junction box, first place the junction box in the connecting frame 304, then start the motor 301, the motor 301 drives the screw rod 302 to rotate, the screw rod 302 drives the lifting block 303 to lift, because the threads on both sides of the screw rod 302 rotate in opposite directions, and then the two lifting blocks 303 move relative to each other, and then the two lifting blocks 303 drive the two connecting frames 304 to move relative to each other, which can clamp and fix the upper and lower sides of the junction box, and then turn the screw rod 305 by hand to drive the limit plate 306 to move, and then the two limit plates 306 clamp and fix one side of the junction box, and at the same time When the first spring 307 is used, the buffer plate 308 will be elastically moved by the first spring 307 to prevent the limit plate 306 from applying too much pressure on the junction box and causing damage to the junction box. When disassembling the connecting plate 2, first pull the pull rod 706 by hand. The pull rod 706 can move the positioning rod 704 outward, so that the positioning rod 704 disengages from the positioning groove 703, releases the limit on the block 702, and then the block 702 on one side of the connecting plate 2 is pulled out from the groove 701 to complete the disassembly of the connecting plate 2 on the bracket. There is no need to use tools to disassemble the entire bracket. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
