[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A busbar trunking housing includes a busbar trunking housing 1, a side plate 2 fixedly connected to the surface of the busbar trunking housing 1, a top cover 3 provided on the top of the busbar trunking housing 1, and a locking structure 4 provided inside the side plate 2. The locking structure 4 includes a sliding groove 41, a fixing rod 42 fixedly connected to the inner wall of the sliding groove 41, a spring 43 sleeved on the outside of the fixing rod 42, a slider 44 slidably connected to the surface of the fixing rod 42, a locking block 45 fixedly connected to the top of the slider 44, and a lever 4 fixedly connected to the surface of the slider 44. 6. Dustproof structures 5 are provided on both sides of the busbar trunking housing 1. The dustproof structure 5 includes a vent 51. A dustproof net 52 is provided on the outside of the vent 51. Fixing bolts 53 are movably connected at the four corners of the dustproof net 52. The two sides of the side plate 2 are provided with sliding grooves 6. Springs 7 are fixedly connected inside the sliding grooves 6. Top blocks 8 are slidably connected inside the sliding grooves 6. A locking structure 4 and auxiliary components are provided. During installation, the square groove on the surface of the top cover 3 is aligned with the locking block 45. The top cover 3 is moved down, and the locking block 45 and the square groove are aligned. When the slot 1 contacts, the inclined surface of the locking block 45 engages with the square slot 1, causing the slider 44 to move on the fixed rod 42, compressing the spring 43 until the locking block 45 extends out of the square slot 1 and engages with the top of the square slot 1, thus fixing the top cover 3. At the same time, the bottom of the top cover 3 contacts the top block 8 and presses down on the top block 8, causing the spring 7 to be in a compressed state. When disassembling, the lever 46 is moved towards the center, causing the slider 44 to move on the fixed rod 42, thus moving the locking block 45 so that the locking block 45 does not interact with the square slot 1. The top cover 3 is lifted by the top block 8 under the action of spring 2 7, thus removing the top cover 3. The housing of the busbar trunking is easy to install and disassemble, and it is easy to repair the inside in case of failure. It has good practicality. A dustproof structure 5 is set up, and the heat generated by the internal circuit is dissipated through the ventilation openings 51 on both sides to ensure the efficiency of use. At the same time, the dustproof net 52 installed by the fixing bolts 53 filters the dust in the air and prevents dust from entering the busbar trunking housing 1 and damaging the internal circuit.

[0024] Furthermore, the cross-section of the busbar housing 1 is U-shaped, and the side plate 2 is fixedly connected to both ends of the U-shape of the busbar housing 1. The top of the side plate 2 is in contact with the bottom of the top cover 3.

[0025] Furthermore, the two ends of the spring 43 are fixedly connected to the inner wall of the slide groove 41 and the surface of the slider 44, respectively. The inner wall of the spring 43 does not contact the surface of the fixed rod 42, and the spring 43 will not interfere with the fixed rod 42 when it is stretched or compressed.

[0026] Furthermore, both slider 44 and lever 46 are slidably connected inside the slide groove 41. The locking block 45 is triangular. Two sets of locking structures 4 are symmetrically arranged on the surface of the side plate 2. Two sets of square grooves are opened on the surface of the top cover 3. The locking block 45 is slidably connected inside the square groove. During installation, the square groove on the surface of the top cover 3 is aligned with the locking block 45. The top cover 3 is moved down, and the locking block 45 contacts the square groove. Through the cooperation of the inclined surface of the locking block 45 with the square groove, the slider 44 is driven to move on the fixed rod 42, compressing the spring 43 until the locking block 45 extends out from the square groove and locks onto the top of the square groove, thereby fixing the top cover 3.

[0027] Furthermore, the two ends of the second spring 7 are fixedly connected to the bottom of the second slide 6 and the bottom of the top block 8, respectively. A rubber pad is provided on the upper surface of the top block 8. After the top cover 3 is fixed to the surface of the side plate 2, the top block 8 abuts against the bottom of the top cover 3 under the action of the second spring 7. The rubber pad prevents damage to the top cover 3 and increases the friction with the top cover 3.

[0028] Furthermore, the slide groove 2 6, the spring 2 7, and the top block 8 constitute a set of auxiliary components. There are four sets of auxiliary components, which correspond to the four corners of the top cover 3 respectively. The four sets of auxiliary structures cooperate with each other, so that the top cover 3 can be lifted when it is disassembled, making disassembly more convenient.

[0029] Furthermore, the dustproof structure 5 is arranged opposite to each other on both sides of the busbar trunking housing 1. Threaded grooves are provided on the side surface of the busbar trunking housing 1 and at the four corners of the dustproof mesh 52. The fixing bolts 53 install the dustproof mesh 52 on the surface of the ventilation opening 51 through the threaded grooves. The heat generated by the internal circuit is dissipated through the ventilation openings 51 on both sides to ensure the efficiency of use. At the same time, the dustproof mesh 52 installed by the fixing bolts 53 filters the dust in the air to prevent dust from entering the busbar trunking housing 1.

[0030] Working principle: During installation, align the square groove on the surface of the top cover 3 with the locking block 45, and lower the top cover 3. The locking block 45 contacts the square groove, and through the engagement of the inclined surface of the locking block 45 with the square groove, the slider 44 moves on the fixed rod 42, compressing the spring 43 until the locking block 45 extends out of the square groove and engages with the top of the square groove, thus fixing the top cover 3. At the same time, the bottom of the top cover 3 contacts the top block 8 and presses down on the top block 8, so that the spring 7 is in a compressed state. For disassembly, [the text abruptly ends here]. The lever 46 at the center is moved, and the slider 44 moves on the fixed rod 42, causing the locking block 45 to move, so that the locking block 45 does not lock with the square groove. At the same time, under the action of the second spring 7, the top cover 3 is lifted by the top block 8, thereby removing the top cover 3. The heat generated by the internal circuit is dissipated through the ventilation openings 51 on both sides to ensure the efficiency of use. At the same time, the dustproof net 52 installed by the fixing bolts 53 filters the dust in the air and prevents dust from entering the busbar trunking housing 1.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
