[0030] Please refer to Figure 1-6 , the present utility model provides a technical solution for a busbar suspension installation mechanism: a busbar suspension installation mechanism includes a busbar 1 and a busbar joint 2. The outer wall of the busbar 1 is provided with a busbar joint 2 to connect and fix the two busbars. The outer wall of the busbar joint 2 is provided with a protective shell 3, which can protect the busbar joint 2 while bearing the suspension installation mechanism at the top. The front surface of the protective shell 3 is provided with an opening and closing plate 4. The opening and closing nature of the opening and closing plate 4 can facilitate the installation and disassembly of the busbar 1 and the busbar 2. The top of the front surface of the opening and closing plate 4 is provided with a buckle assembly for locking the opening and closing plate 4. The top of the protective shell 3 is provided with a support shell 9 for connecting the bottom protective shell 3 and the internal slide plate 12. The inside of the support shell 9 is provided with a telescopic assembly, so that the support shell 9 and the slide plate 12 can adjust the length to adapt to the distance between the busbar 1 and the ceiling. The top of the support shell 9 is provided with a fixing member 16 for connecting the bottom support shell 9, the inner swing member 17 and the top connecting member 21. The inner side of the fixing member 16 is provided with a swing member 17, which cooperates with the lengths of the support shell 9 and the slide plate 12 to adjust the distance between the left and right support shells, so as to make the overall structure firm. The outer wall of the swing member 17 is provided with a strip frame 18 to cooperate with the inner swing member 17 to adjust the length. The top of the swing member 17 is provided with a screw 19, and the outer wall of the screw 19 is provided with a nut 20. The screw 19 and the strip frame 18 are used to fix the swing member 17 at a corresponding position to ensure the length of the swing member 17. The top of the fixing member 16 is provided with a connecting member 21 for connecting the bottom fixing member 16 and the top ceiling.

[0031] The bottom of the front surface of the protective shell 3 is provided with two convex blocks, and the inside of the two convex blocks is provided with a pin shaft connected to the opening and closing plate 4, which can make the opening and closing plate 4 open and close on the front surface of the protective shell 3.

[0032] The buckle assembly includes a first convex block 5 for connecting the clamping plate 6 to the opening and closing plate 3. The first convex block 5 is arranged on the front surface of the opening and closing plate 4. The bottom of the first convex block 5 is provided with a swingable clamping plate 6, which swings up and down to control the locking buckle 7 to complete the locking and unlocking of the opening and closing plate 4. The left and right sides of the clamping plate 6 are provided with swingable locking buckles 7, which can lock the opening and closing plate 4 under the control of the clamping plate 6. The top of the locking buckle 7 is provided with a second convex block 8 to cooperate with the locking buckle 7 to complete the locking work.

[0033] The inside of the first bump 5 is provided with a pin shaft bent on both sides, and the pin shaft inside the first bump 5 is connected to the clamping plate 6 to ensure that the clamping plate 6 can swing.

[0034] The telescopic assembly includes a chute 10 provided inside the support shell 9 to enable the slide plate 12 to slide up and down inside. A hook tooth 11 is provided on the right side of the chute 10. When the pin 15 slides to the hook tooth, it can unidirectionally hold the pin 15 and ensure that the pin 15 can slide upward. A slide plate 12 is provided inside the support shell 9 to adjust the length by sliding up and down. An elastic piece 13 is provided on the front surface of the slide plate 12 to apply a thrust force in the direction of the hook tooth to the pin 15 when the pin 15 is not stuck on the hook tooth 11. When the slide plate 12 slides to the topmost position, due to the narrowing of the chute, the hook at the bottom end of the elastic piece will catch the card slot of the special-shaped wheel, preventing the pin 15 from being stuck on the hook tooth. A special-shaped wheel 14 is provided on the front surface of the slide plate 12 and is used in cooperation with the elastic piece 13 and the pin 15 to complete the control of the slide plate 12. A pin 15 is provided at the bottom end of the special-shaped wheel 14. When the pin 15 slides to the hook tooth position, it will hold the slide plate 12.

[0035] A card hook is provided at the bottom end of the elastic piece 13, and a card slot for cooperating with the card hook of the elastic piece 13 is provided on the left side of the special-shaped wheel 14. The top end of the chute 10 narrows to the left, and the bottom end of the chute 11 narrows to the right. When the slide plate 12 slides to the topmost position, due to the narrowing of the top end of the chute 10 to the left, the card slot on the left side of the special-shaped wheel 14 is caught by the card hook of the elastic piece 13, ensuring that the pin 15 will not be caught by the hook tooth 11. When the slide plate 12 slides to the bottommost position, due to the narrowing of the bottom end of the chute 10 to the right, the special-shaped wheel 14 will be disengaged from the control of the elastic piece 13, and the pin 15 will be able to be caught by the hook tooth.

[0036] A through hole is provided at the bottom end of the front surface of the slide plate 12, and a through hole corresponding to the slide plate 12 is provided at the center of the special-shaped wheel 14. The slide plate 12 and the special-shaped wheel 14 are connected by a pin shaft to ensure that the special-shaped wheel 14 can rotate around the pin shaft.

[0037] A chute is provided at the top end of the strip frame 18, and the width of the chute is smaller than the diameter of the bottom end of the nut 20. When the nut 20 is tightened, the screw rod 19 will drive the swing piece 17 at the bottom end upward. Since the width of the chute is smaller than the diameter of the bottom end of the nut 20, the swing piece 17 will be fixed after tightening.

[0038] The screw rod 19 can slide in the chute at the top end of the strip frame 18. The screw rod 19 can adjust the length in cooperation with the sliding of the swing piece 17 and then fix it. The bottom end of the screw rod 19 is connected to the top end of the swing piece 17.

[0039] A through hole is provided at the top end of the fixing piece 16, and a through hole corresponding to the fixing piece 16 is provided at the center of the connecting piece 21. The fixing piece 16 and the connecting piece 21 are connected by a pin shaft for the fixing piece 16 to swing left and right in cooperation with the adjustment of the length of the swing piece 17.

[0040] Working principle: When the busway needs to be installed by suspension, first fix the connector 21 on the ceiling, and then adjust the lengths of the sliding plate 12 and the support shell 9 according to the situation of the ceiling. When the sliding plate 12 is pulled upward, the internal pin 15 will be stuck on the hook teeth 11 until the required length is adjusted. When the length needs to be adjusted again, slide the sliding plate 12 upward to the highest position. At this time, since the top of the chute 10 becomes narrower to the left, the card slot of the special-shaped wheel 14 will be caught by the hook of the elastic piece 13. At this time, the sliding plate 12 can slide downward without being blocked. When the sliding plate 12 slides to the lowest position, since the chute 10 becomes narrower to the right, the card slot of the special-shaped wheel 14 will release the lock of the elastic piece 13. At this time, when the sliding plate 12 slides to the required position, the pin 15 will be caught by the hook teeth 11. Since the swing piece 17 and the strip frame 18 need to fix the support shell 9 and the sliding plate 12, when the lengths of the support block 9 and the sliding plate 12 are adjusted, the lengths of the swing piece 17 and the strip frame 18 also need to be adjusted. At this time, the nut 20 needs to be loosened and rotated until the nut 20 and the screw rod 19 can control the swing piece 17 to slide in the chute at the top of the strip frame 18. When it slides to the corresponding position and the nut 20 is tightened, the swing piece 17 will be fixed at the corresponding position of the strip frame 18 by using the property of the fixed connection between the screw rod 19 and the swing piece 17. And at this time, the fixing piece 16 will also swing at the bottom of the connector 21 due to the inclination. After the above steps are completed, pull the clamping plate 6 upward from bottom to top to release the lock of the lock 7 on the second convex block 8. At this time, the opening and closing plate 4 can swing downward so that the inner wall of the protective shell 3 is exposed. Then the busway 1 and the busway joint 2 can be placed inside the protective shell 3. After placing them, lock the opening and closing plate 4 in the same way to complete the fixation of the busway 1 and the busway joint 2. The above is the overall suspension installation method of the busway.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
