[0029] See also Figure 1-5 A connecting elbow for power distribution equipment, comprising a shell 1, a cover 2 movably provided on the upper end of the shell 1, a plurality of support seats 3 provided in the shell 1, the upper end of each support seat 3 is recessed inward to form a plurality of fixed chambers 4, two support plates 5 are provided in each fixed chamber 4, two limiting rods 6 are fixedly provided between the two support plates 5, an arc-shaped clamping plate 7 is rotatably provided on each limiting rod 6, a first spring 8 is fixedly connected between each clamping plate 7 and the fixed chamber 4, and a guide plate 9 is provided on the upper end of each clamping plate 7;

[0030] A plurality of mounting seats 10 are provided on the outside of the cover body 2 , and an inserting block 11 is provided at the lower end of each mounting seat 10 . A plurality of fixing shells 12 that match the inserting blocks 11 are provided on the outside of the housing 1 .

[0031] In this embodiment, when it is necessary to lay cables within the connecting elbow, the cables are placed above the corresponding multiple fixing chambers 4 and between the two guide plates 9. The cables are then moved downward, causing the cables to push the two guide plates 9 in a separating direction. The guide plates 9 drive the clamping plates 7 to rotate about the limit rods 6. The first spring 8 is compressed, and the cables are moved downward between the two clamping plates 7. The first spring 8 pushes the clamping plates 7 to rotate in adjacent directions, thereby clamping and securing the cables. The same method can be used to secure multiple cables between the two clamping plates 7 within the corresponding multiple fixing chambers 4, allowing them to be laid and organized simultaneously.

[0032] More specifically, the cable can be placed between the two clamping plates 7. Under the push of the first spring 8, the two clamping plates 7 clamp and fix the cable. When the cover 2 needs to be installed, the cover 2 is placed above the shell 1. The cover 2 drives the multiple mounting seats 10 to move, and the mounting seats 10 drive the insertion block 11 to move, so that the insertion rod is inserted into the fixed shell 12, thereby installing the cover 2.

[0033] See also Figure 1-5 As an implementation method for fixing the plug block 11: a fixed block 13 that cooperates with the plug block 11 is slidably connected to the fixed shell 12 through a track structure, and the plug block 11 and the fixed block 13 are respectively provided with a matching inclined surface 14, and a plurality of second springs 15 are fixedly connected between the fixed block 13 and the fixed shell 12. A push rod 16 is fixedly provided on one side of the fixed block 13, and one end of the push rod 16 extends to the outside of the fixed shell 12.

[0034] Specifically, when the insert block 11 is inserted into the fixed shell 12, the inclined surface 14 on the insert block 11 contacts the inclined surface 14 of the fixing block 13. When the insert block 11 continues to move downward, the insert block 11 pushes the fixing block 13 through the inclined surface 14, so that the fixing block 13 moves along the sliding connection with the fixed shell 12, and the second spring 15 is compressed. When the inclined surface 14 of the insert block 11 is separated from the inclined surface 14 of the fixing block 13, the fixing block 13 moves back to its original position under the push of the second spring 15, thereby fixing the insert block 11. When the cover body 2 needs to be opened, the push rod 16 is pushed, and the push rod 16 will drive the fixing block 13 to move. The second spring 15 is compressed, and the fixing block 13 is separated from the insert block 11. At this time, the cover body 2 can be pulled upward, and the cover body 2 drives the mounting seat 10 and the insert block 11 to move, thereby removing the cover body 2.

[0035] See also Figure 1-5, as an implementation method for connecting the entire connecting elbow and the wire trough pipe 20: two first mounting grooves 17 are symmetrically provided at the lower end of the cover body 2, and two second mounting grooves 18 that match the first mounting grooves 17 are provided in the shell 1, and the first mounting groove 17 and the second mounting groove 18 are both movably connected with a mounting ring 19, and one end of the mounting ring 19 is fixedly connected to the wire trough pipe 20.

[0036] Specifically, the mounting rings 19 of two adjacent wire trough tubes 20 are placed in the second mounting groove 18, and the mounting rings 19 drive the wire trough tubes 20 to be connected to the shell 1. When the cover body 2 is fixed to the upper end of the shell 1, the upper end of the mounting ring 19 will be inserted into the first mounting groove 17, fixing the mounting ring 19, thereby fixing the wire trough tubes 20 at both ends of the shell 1.

[0037] In summary, when the overall equipment is in use:

[0038] When it is necessary to lay cables in the connecting elbow, the cables are placed above the corresponding multiple fixing chambers 4 and between the two guide plates 9. The cables are then moved downward, pushing the two guide plates 9 in the separation direction. The guide plates 9 drive the clamping plates 7 to rotate around the limit rod 6. The first spring 8 is compressed, and the cables are moved downward between the two clamping plates 7. Under the push of the first spring 8, the clamping plates 7 rotate in the adjacent direction, thereby clamping and fixing the cables. The same method can be used to fix multiple cables between the two clamping plates 7 in the corresponding multiple fixing chambers 4, so that they can be laid and organized at the same time.

[0039] When it is necessary to fix the cover body 2 to the shell 1, the cover body 2 is placed above the shell 1, and the cover body 2 drives the multiple mounting seats 10 to move, and the mounting seats 10 drive the plug block 11 to move, so that the insertion rod is inserted into the fixed shell 12, and the inclined surface 14 on the plug block 11 contacts the inclined surface 14 of the fixed block 13. When the plug block 11 continues to move downward, the plug block 11 pushes the fixed block 13 through the inclined surface 14, so that the fixed block 13 moves along the sliding connection with the fixed shell 12, and the second spring 1 5 is compressed. When the inclined surface 14 of the inserting block 11 separates from the inclined surface 14 of the fixing block 13, the fixing block 13 moves back to its original position under the push of the second spring 15, thereby fixing the inserting block 11. When it is necessary to open the cover 2, the push rod 16 is pushed, and the push rod 16 drives the fixing block 13 to move. The second spring 15 is compressed, and the fixing block 13 separates from the inserting block 11. At this time, the cover 2 can be pulled upward, and the cover 2 drives the mounting base 10 and the inserting block 11 to move, thereby removing the cover 2.

[0040] When the entire connecting elbow needs to be connected to two adjacent wire trough pipes 20, the mounting rings 19 of the two adjacent wire trough pipes 20 are placed in the second mounting groove 18, and the mounting ring 19 drives the wire trough pipes 20 to be connected to the shell 1. When the cover body 2 is fixed to the upper end of the shell 1, the upper end of the mounting ring 19 will be inserted into the first mounting groove 17, fixing the mounting ring 19, thereby fixing the wire trough pipes 20 at both ends of the shell 1.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
