[0017] 2. For the structure frame of the distribution cabinet, when the crossbeam needs to be moved, the sleeve is pressed upward to make the limit ring move upward in the guide hole, and then the sleeve is pushed to one side to make the sleeve and the limit ring move from the guide hole to the trapezoidal slide groove. At the same time, the sleeve drives the connecting plate to move to one end through the T-shaped rod, and the connecting plate drives the adapter plate to rotate around the supporting column through the connecting column inside the second slide groove. Another connecting column on the supporting column will drive the second connecting block to move in the opposite direction of movement of the connecting plate through the first slide groove. At the same time, the second connecting block will drive the second pin to move out of the second positioning hole, and then the crossbeam can be moved. The operation is simple and avoids the operator accidentally moving or pressing the sleeve, causing the crossbeam to tilt to one side or fall downward, resulting in damage to the electrical equipment on the crossbeam.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, as Figure 1 - Fig.11 As shown, an embodiment of the present invention provides a distribution cabinet structure frame, including a cabinet body 1, two symmetrical guide rails 2 are fixedly connected to the two opposite inner sides of the cabinet body 1, a plurality of first positioning holes 5 are opened in a linear array on one side of the guide rail 2, a longitudinal beam 3 is slidably matched on the two guide rails 2, a plurality of cross beams 7 are slidably matched between the two longitudinal beams 3, and a first plug-in assembly 4 is provided at both ends of the longitudinal beam 3; Specifically, the first plug assembly 4 includes a first latch 401 that is slidably matched with the longitudinal beam 3, the first latch 401 is plugged into the first positioning hole 5, one end of the first latch 401 is fixedly connected to a first connecting block 402 that is slidably matched inside the longitudinal beam 3, and the first connecting block 402 is fixedly connected to a first spring 403 at one end away from the first latch 401. When the first connecting block 402 moves toward the side close to the first spring 403, the first spring 403 is compressed, so as to utilize the rebound of the first spring 403 to assist the first latch 401 in resetting. One side of the first connecting block 402 is fixed A guide rod 404 is connected, and a steering plate 405 is slidably matched inside the longitudinal beam 3. A guide bevel groove 406 is provided on one side of the steering plate 405. The guide bevel groove 406 slidably matches with the guide rod 404. By pushing the steering plate 405 to move up and down, the guide rod 404 slides in the guide bevel groove 406, thereby pushing the guide rod 404 to move left and right in the horizontal direction. At the same time, the guide rod 404 will drive the first connecting block 402 to move synchronously, and the first connecting block 402 will drive the first pin 401 to move synchronously, so that the first pin 401 is inserted into or removed from the corresponding first positioning hole 5.

[0022] A second spring 407 is fixedly connected to one side of the steering plate 405 inside the longitudinal beam 3. When the steering plate 405 moves toward the side close to the second spring 407, the second spring 407 is compressed, so that the rebound of the second spring 407 is used to assist the steering plate 405 in resetting. A connecting rod 408 is fixedly connected to the other side of the steering plate 405. A guide block 409 is fixedly connected to one end of the connecting rod 408 away from the steering plate 405. A connecting chamfer 410 is provided on one side of the guide block 409. An isosceles trapezoidal block 11 is slidably fitted between the two guide blocks 409. The connecting chamfer 410 on one side of the guide block 409 and the hypotenuse angle of the isosceles trapezoidal block 11 are complementary angles to each other. The isosceles trapezoidal block 11 is slidably matched with the longitudinal beam 3, and a third spring 12 is fixedly connected to one end of the isosceles trapezoidal block 11 inside the longitudinal beam 3, and a pressure rod 13 is fixedly connected to the other end of the isosceles trapezoidal block 11 and slidably matched with the longitudinal beam 3. By pressing the pressure rod 13, the isosceles trapezoidal block 11 is pushed to move toward the side close to the third spring 12 and compress the third spring 12. At the same time, the two hypotenuses of the isosceles trapezoidal block 11 are respectively attached to the hypotenuses of the connecting chamfers 410 of the two guide blocks 409 and slide against each other, thereby pushing the two guide blocks 409 to move in opposite directions. When the pressure rod 13 is no longer pressed, the compressed third spring 12 will drive the isosceles trapezoidal block 11 to reset.

[0023] The operation process of this embodiment is as follows: when it is necessary to move the two symmetrical longitudinal beams 3, the pressure rods 13 on the two longitudinal beams 3 are pressed at the same time, the pressure rods 13 push the isosceles trapezoidal block 11 to move toward the side close to the third spring 12 and compress the third spring 12, and the isosceles trapezoidal block 11 will push the guide block 409 located above to move upward, and push the guide block 409 located below to move downward, and the guide block 409 pushes the steering plate 405 to move toward the side close to the second spring 407 through the connecting rod 408 to compress the second spring 407, and at the same time, the steering plate 405 drives the guide rod 404 to move in the horizontal direction through the guiding inclined groove 406, and the guide rod 404 pushes the first connecting block 402 to move toward the side close to the first spring 403 and compress the first spring 403, and at the same time, the first connecting block 402 drives the first latch 401 to move synchronously until the end of the first latch 401 is completely moved out of the first positioning hole 5, and when the four first latches 401 are all moved out of the corresponding first positioning holes 5, they can be pushed at the same time. The two longitudinal beams 3 are moved to slide along the guide rails 2 to reserve space for wiring and installing heat dissipation devices of the distribution cabinet, and at the same time, it is convenient for maintenance personnel to inspect the electrical equipment on the crossbeam 7 at close range at the cabinet door. When the two longitudinal beams 3 move to the appropriate position and approach the nearest first positioning hole 5 on the guide rail 2, the two pressure rods 13 can be released, and the compressed third spring 12 drives the isosceles trapezoidal block 11 to reset first, and then the compressed second spring 407 begins to drive the steering plate 405 to reset. When resetting, the steering plate 405 will drive the guide rod 404 to move in the opposite direction of the previous movement, and at the same time, cooperate with the compressed first spring 403 to push the first connecting block 402 to move toward the side away from the first spring 403, and the first connecting block 402 will push the first pin 401 to move synchronously. At this time, in order to avoid the first pin 401 not being inserted into the corresponding first positioning hole 5, the two longitudinal beams 3 should be moved back and forth in a small amplitude. When the two longitudinal beams 3 can no longer be moved back and forth, it can be inferred that the first pin 401 has been inserted into the corresponding first positioning hole 5.

[0024] Embodiment 2, as Figure 1 - Fig.11 As shown, based on the specific embodiment 1, a plurality of second positioning holes 6 are provided in a linear array on one side of the longitudinal beam 3, second plug-in components 8 are provided at both ends of the cross beam 7, and two symmetrical installation grooves 14 are provided through one side of the cross beam 7.

[0025] The second plug-in assembly 8 includes a second latch 801 that is slidably matched with the cross beam 7, the second latch 801 is plugged into the second positioning hole 6, one end of the second latch 801 is fixedly connected to a second connecting block 802, one side of the second connecting block 802 is penetrated with a first sliding groove 803, a connecting plate 804 is slidably matched inside the cross beam 7, one side of the connecting plate 804 is penetrated with a second sliding groove 805, a support column 806 is fixedly connected inside the cross beam 7, and an adapter plate 807 is rotatably matched around the side surface of the support column 806, and one side of the adapter plate 807 is fixedly connected to two symmetrical connecting columns 808, and the two connecting columns 808 are respectively connected to the first sliding groove 803 and the second The slide groove 805 slides together, and a fourth spring 809 is fixedly connected to one end of the connecting plate 804 inside the crossbeam 7. By pushing the connecting plate 804 to move toward the end close to the fourth spring 809, the fourth spring 809 is compressed, and when the second slide groove 805 moves, it will drive the adapter plate 807 to rotate around the support column 806 through the connecting column 808 inside it. Another connecting column 808 on the support column 806 will drive the second connecting block 802 to move in the opposite direction of the connecting plate 804 through the first slide groove 803. At the same time, the second connecting block 802 will drive the second pin 801 to move out of the second positioning hole 6.

[0026] The other end of the connecting plate 804 is fixedly connected to a T-shaped rod 810, and a sleeve 811 is slidably matched with the side surface of the T-shaped rod 810. A fifth spring 812 is fixedly connected to one end of the T-shaped rod 810 inside the sleeve 811, and a limiting ring 813 is fixedly connected to the side surface of the sleeve 811. A trapezoidal slide groove 9 that slidably matches with the sleeve 811 is provided at the bottom of the crossbeam 7. A guide hole 10 that slidably matches with the limiting ring 813 is provided at the bottom of the crossbeam 7. Due to the restriction of the limiting ring 813 of the sleeve 811, the sleeve 811 It is impossible to move directly from the guide hole 10 to the trapezoidal slide groove 9. It is necessary to first press the sleeve 811 upwards to allow the limiting ring 813 to move upwards in the guide hole 10. After moving into place, the sleeve 811 can be pushed to one side to allow the sleeve 811 and the limiting ring 813 to move from the guide hole 10 to the trapezoidal slide groove 9. At the same time, the sleeve 811 drives the connecting plate 804 to move toward the end close to the fourth spring 809 through the T-shaped rod 810, so that the end of the second pin 801 is completely moved out of the second positioning hole 6.

[0027] The operation process of this embodiment is as follows: when it is necessary to move the upper and lower positions of the cross beam 7, the sleeve 811 is first pressed upward so that the limiting ring 813 moves upward in the guide hole 10 first, and at the same time, the T-shaped rod 810 moves in the sleeve 811 and compresses the fifth spring 812, and then the sleeve 811 is pushed to one side so that the sleeve 811 and the limiting ring 813 move from the guide hole 10 to the trapezoidal slide groove 9, and at the same time, the sleeve 811 drives the connecting plate 804 to move toward one end close to the fourth spring 809 through the T-shaped rod 810 and compresses the fourth spring 809, and the connecting plate 804 drives the adapter plate 804 through the connecting column 808 inside the second slide groove 805. 07 rotates around the support column 806, and another connecting column 808 on the support column 806 will drive the second connecting block 802 to move in the opposite direction of the connecting plate 804 through the first sliding groove 803. At the same time, the second connecting block 802 will drive the second latch 801 to move out of the second positioning hole 6. When the second latches 801 at both ends of the crossbeam 7 are all moved out of the corresponding second positioning holes 6, the crossbeam 7 can be moved. When the crossbeam 7 moves to a suitable position and approaches the nearest second positioning hole 6 on the longitudinal beam 3, the sleeve 811 is released, and the compressed fourth spring 809 begins to rebound and drives the connecting plate 804 to a direction away from the fourth spring 809. The connecting plate 804 drives the adapter plate 807 to rotate in the opposite direction around the support column 806 through the connecting column 808 inside the second slide groove 805. Another connecting column 808 on the support column 806 drives the second connecting block 802 to move in the opposite direction of the connecting plate 804 through the first slide groove 803. At the same time, the second connecting block 802 drives the second latch 801 to move synchronously. At this time, in order to avoid the second latch 801 not being inserted into the corresponding second positioning hole 6, the crossbeam 7 should be moved up and down in a small range. When the crossbeam 7 can no longer be moved up and down, it can be inferred that the second latch 801 has been inserted into the corresponding second positioning hole 6 and When the fourth spring 809 drives the connecting plate 804 to move, the connecting plate 804 will drive the sleeve 811 and the limiting ring 813 to move from the trapezoidal slide groove 9 to the guide hole 10 through the T-shaped rod 810, and when the sleeve 811 and the limiting ring 813 return to the guide hole 10, the compressed fifth spring 812 begins to rebound and drives the sleeve 811 and the limiting ring 813 to move downward, so that the sleeve 811 and the limiting ring 813 cannot move directly from the guide hole 10 to the trapezoidal slide groove 9, so as to prevent the operator from accidentally moving or pressing the sleeve 811, causing the beam 7 to tilt to one side or fall downward, resulting in damage to the electrical equipment on the beam 7.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
