The U-shaped plate 4 is provided with two extension strips 52 extending toward the inner wall of the bottom of the U-shaped plate 4, and each extension strip 52 is provided with a sliding block 53 at one end away from the moving block 51. The sliding block 53 can be slidably arranged in the corresponding strip-shaped slide groove 41. The outer wall of the U-shaped plate 4 on one side close to the lower shell 2 is provided with a first rectangular avoidance groove 42 for avoiding the moving block 51. Each side of the lower shell 2 is also provided with a second rectangular avoidance groove 21 for avoiding the extension strip 52. The end of the bottom of each U-shaped plate 4 close to the first rectangular avoidance groove 42 is provided with a first strip through groove 43 cooperating with the sliding block 53. The length direction is perpendicular to the length direction of the two strip-shaped slide grooves 41; a driving gear 32 is also arranged at the center of each connecting block 3, and the driving gear 32 is coaxially arranged with the corresponding flip axis 31; a mounting plate 44 is arranged at the end of each U-shaped plate 4 away from the corresponding lower shell 2, and each mounting plate 44 is provided with a rack 441 that cooperates with the driving gear 32, and each moving block 51 is provided with a third rectangular avoidance groove 513 for avoiding the rack 441; a positioning plate 45 for pushing the extension strip 52 is also slidably arranged in each U-shaped plate 4, and a positioning spring 46 is arranged between the positioning plate 45 and the corresponding mounting plate 44.

[0035] Under the elastic force of multiple positioning springs 46, the positioning plate 45 can push the corresponding extension strip 52 to be located at the staggered position of the strip slide groove 41 and the first strip through groove 43. At this time, the sides of the upper shell 1 and the lower shell 2 correspond one by one to form a power box. When the power box needs to be repaired, the staff pushes the upper shell 1 according to the position, and the upper shell 1 moves along the corresponding moving direction. The second rectangular avoidance groove 21 set on the lower shell 2 can provide avoidance space for the movement of the moving block 51. At this time, the sliding block 53 of the upper shell 1 along the moving direction can overcome the elastic force of the corresponding return spring and move along the corresponding strip slide groove 41. The sliding blocks 53 on both sides of the upper shell 1 along the moving direction can move from the strip slide groove 41 to the first strip through groove 43, and through The first rectangular avoidance groove 42 on the U-shaped plate 4 is moved out from the U-shaped plate 4. At this time, the upper shell 1 and the lower shell 2 are arranged alternately. As the upper shell 1 continues to move, the driving gear 32 on the connecting block 3 can contact the rack 441 arranged on the mounting plate 44, so that the upper shell 1 can rotate along the corresponding flip axis 31, thereby separating the upper shell 1 from the lower shell 2, which is convenient for staff to carry out maintenance. When the maintenance is completed, the upper shell 1 can be reset under the elastic force of the reset spring to ensure the sealing effect of the power box; and the moving block 51 on the side of the upper shell 1 can make the upper shell 1 open in multiple directions, which not only improves the convenience of maintaining the power box, but also can maintain its internal electrical components in different directions, thereby improving the maintenance efficiency.

[0036] See also Figures 5 to 9 As shown, each strip-shaped slide groove 41 is provided with limiting grooves 411 on the inner walls on both sides along the length direction, and each sliding block 53 is provided with limiting strips 531 on the outer walls on both sides. The limiting strips 531 can be slidably arranged in the corresponding limiting grooves 411, and each limiting strip 531 is provided with a second strip through groove 532 at both ends, and an extension block 533 is slidably arranged in each second strip through groove 532. The divergent ends of two adjacent extension blocks 533 are provided with arc-shaped guiding parts 534, and each extension block 533 is provided with a resistance strip 535 on both sides. The inner walls on both sides of each second strip through groove 532 are provided with a third strip through groove 5321 for avoiding the resistance strip 535, and each extension block 533 is connected to the inner wall at the bottom of the corresponding second strip through groove 532 through a telescopic spring 536.

[0037] In order to make the connection between the upper shell 1 and the lower shell 2 more stable, limit strips 531 are provided on both sides of the sliding block 53, and the limit strips 531 can be slidably arranged in the corresponding limit grooves 411. The extension blocks 533 at both ends of the limit strip 531 are located at the ends of the corresponding limit strips 531 under the elastic force of the telescopic spring 536. When the sliding block 53 is located at the intersection of the strip slide groove 41 and the first strip through-groove 43, the extension block 533 can play a fixing role, thereby preventing the sliding block 53 from sliding out of the strip slide groove 41. When the sliding block 53 moves along the length direction of the corresponding first strip through-groove 43, the arc-shaped guide arranged on the extension block 533 The guide portion 534 and the arc-shaped guide portion contact the inner wall of the first strip through groove 43, so that the extension block 533 can overcome the elastic force of the telescopic spring 536 to move, so that the sliding block 53 can smoothly move out of the U-shaped plate 4 along the first strip through groove 43, thereby facilitating the separation of the upper shell 1 from the lower shell 2. When the upper shell 1 is reset, the sliding block 53 that has moved out of the U-shaped plate 4 can return to the inside of the U-shaped plate 4 along the corresponding first strip through groove 43 through the cooperation of the triangular guide portion 518, and under the action of the elastic force of the telescopic spring 536, the extension block 533 is extended into the limiting groove 411, thereby fixing the upper shell 1 and the lower shell 2.

[0038] It is particularly noted that the diverging ends in this application are ends that are away from each other.

[0039] See also Figure 7 As shown, a sealing plate 514 for sealing the second rectangular avoidance groove 21 is provided at the bottom of each moving block 51 .

[0040] By providing the sealing plate 514 , the second rectangular avoidance groove 21 can be sealed to prevent dust and impurities from entering between the upper shell 1 and the lower shell 2 and causing damage to components.

[0041] See also Figures 5 to 7 As shown, circular grooves 515 are provided on the outer walls on both sides of each moving block 51. The circular grooves 515 are coaxially arranged with the corresponding rotating holes 512. The diameter of the circular grooves 515 is larger than the diameter of the rotating holes 512. A horizontal torsion spring 33 is provided at one end of each flip shaft 31 extending into the circular groove 515.

[0042] When the rack 441 is separated from the driving gear 32, under the action of the torsion of the horizontal torsion spring 33, the connecting block 3 and the corresponding moving block 51 can be made parallel to each other. Not only can the sliding block 53 arranged on the moving block 51 be accurately moved to the corresponding first strip groove 43 when the upper shell 1 is reset, but also the volume collision between the moving block 51 and the lower shell 2 can be avoided during the reset process of the upper shell 1.

[0043] See also Figures 5 to 8As shown, each mounting plate 44 is also provided with a locking mechanism 6 for limiting the position of the moving block 51; each group of locking mechanisms 6 includes a locking rod 61; two vertical plates 442 are provided on the top of each mounting plate 44, and a locking hole 443 is provided on each vertical plate 442; two rotating rods 62 are mirrored on the outer wall of one end of each locking rod 61 along the length direction along the axial direction, and the rotating rod 62 is rotatably arranged in the corresponding locking hole 443, and the locking rod 61 is located between the two vertical plates 442, and a clamping rod 63 is provided at one end of each locking rod 61 away from the vertical plate 442, and a reset torsion spring 64 is also provided on each rotating rod 62; two horizontal plates 516 are provided on the side of each moving block 51 close to the corresponding mounting plate 44, and V-shaped limiting portions 517 are provided on the opposite sides of the two horizontal plates 516, and a space for the locking rod 61 to pass through is formed between the two limiting portions 517, and a triangular guiding portion 518 is provided at one end of each horizontal plate 516 away from the moving block 51.

[0044] By setting a reset torsion spring 64, the locking rod 61 can be set in a horizontal state. As the moving block 51 moves, the rack 441 meshes with the driving gear 32, so that the upper shell 1 can rotate along the axis of the corresponding flip shaft 31. As the moving block 51 moves, the triangular guide portion 518 contacts the clamping rod 63, so that the rotating rod 62 overcomes the torsion of the reset torsion spring 64 and rotates. At this time, the clamping rod 63 moves to the recess along the V-shaped limiting portion 517. At this time, under the elastic force of the positioning spring 46, the upper shell 1 is in a locked state, which is convenient for the staff to handle the power box; when the processing is completed, the staff continues to push the upper shell 1, so that the clamping rod 63 can slide out of the recess, thereby releasing the lock on the moving rod. Under the elastic force of the positioning spring 46, the upper shell 1 can be reset, thereby completing the entire maintenance work, and the distance between the upper end protrusion and the moving block 51 is smaller than the distance between the lower end protrusion and the moving block 51, thereby ensuring the smoothness of the movement of the clamping rod 63.

[0045] It is particularly noted that the facing sides in the present application are the sides that are close to each other.

[0046] See also Figure 5 and Figure 6 As shown, each positioning plate 45 is provided with L-shaped slide bars 451 at both ends along the length direction, and each U-shaped plate 4 is provided with horizontal slide grooves 47 on both sides of the inner wall. The end of the L-shaped slide bar 451 away from the positioning plate 45 can be slidably arranged in the corresponding horizontal slide groove 47.

[0047] Under the elastic force of the positioning spring 46, the corresponding sliding block 53 can be located at the intersection of the corresponding strip slide groove 41 and the first strip through groove 43. At this time, the L-shaped slide bar 451 and the horizontal slide groove 47 are in contact with the side close to the lower shell 2, so that the position of the positioning plate 45 can be limited to ensure the accuracy between the upper shell 1 and the lower shell 2, and the positioning plate 45 can perform secondary limiting on the sliding block 53, thereby further ensuring the stability of the upper shell 1 and the lower shell 2.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
