[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits.

[0003] Announcement No. "CN220492419U" provides a power distribution cabinet frame, including two side frames, first fixed frames are arranged at the front and rear of the bottom of the inner wall of the two side frames, a first sliding frame is slidably connected between each two first fixed frames, and second fixed frames are arranged at the front and rear of the top of the inner wall of the two side frames. The device can quickly fix the first fixed frame and the second fixed frame through the setting of the fixing component, so that the side frame can be conveniently connected with the first fixed frame and the second fixed frame, and has high stability after connection, which reduces the workload of the staff and improves the work efficiency;

[0004] However, the above solution still has the following defects:

[0005] When used on a ship, severe turbulence may cause the fixed components to shake, thereby damaging the entire frame. In the prior art, multiple distribution cabinets are mostly connected into a whole to resist turbulence. However, since the heat dissipation ports of the distribution cabinets are often arranged on both sides, this method is not conducive to the heat dissipation of the distribution cabinets. If heat is dissipated by reserving a gap between the two distribution cabinets, the overall connection strength will be reduced. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] A power distribution cabinet frame comprises a frame body 1, a limit seat 2 is arranged between two frame bodies 1, a connection mechanism for connecting with the two frame bodies 1 at the same time is arranged on the limit seat 2, and two sides of the limit seat 2 are respectively attached to the side surfaces of the two frame bodies 1;

[0027] The connecting mechanism includes a base 3, a threaded rod 4, a traction seat 5, a connecting arm 6 and a cross bar 7. The base 3 is arranged in the middle of the limit seat 2. One end of the threaded rod 4 is fixed on the base 3, and the other end of the threaded rod 4 is rotatably arranged on the surface of the limit seat 2. The bottom of one of the threaded rods 4 extends into the inside of the limit seat 2 and rotates under the drive of the traction mechanism. The traction seat 5 is threadedly connected to the surface of the threaded rod 4. The cross bar 7 is fixed on the frame body 1. The two ends of the connecting arm 6 are respectively hinged on the cross bar 7 and the traction seat 5. The depth of the limit seat 2 is the same as the depth of the frame body 1, and the top of the limit seat 2 is flush with the top of the frame body 1.

[0028] See also Figure 1 and 2The function of the base 3 is to connect the two threaded rods 4. After the threaded rods 4 are rotated by the traction mechanism, each threaded rod 4 can drive the traction seat 5 to move linearly on its surface. The movement mode of the two traction seats 5 is to move closer to or away from each other. Since the cross bar 7 is fixed, the vertical distance between the traction seat 5 and the cross bar 7 will change during vertical movement. Then, in conjunction with the rotatable connecting arm 6, the horizontal distance between the cross bar 7 and the traction seat 5 can be adjusted to adapt to different usage environments.

[0029] The traction mechanism includes a rotating shaft 8, a handle 9 and a transmission member. One end of the rotating shaft 8 passes through and rotates on the limit seat 2. The handle 9 is fixed to one end of the rotating shaft 8. The other end of the rotating shaft 8 is connected to the threaded rod 4 through a transmission member. The transmission member is two mutually perpendicular and meshing bevel gears 12. The two bevel gears 12 are respectively fixed to the threaded rod 4 and one end of the rotating shaft 8.

[0030] See also Figure 2 and 4 The handle 9 can drive the rotating shaft 8 to rotate, and the rotating shaft 8 can drive the threaded rod 4 to rotate unidirectionally through the mutual engagement of the two bevel gears 12, thereby making the two threaded rods 4 rotate synchronously. At this time, the two threaded rods 4 can respectively drive the two traction seats 5 to move away from or approach each other. When the two traction seats 5 move away from each other, it means that the upper traction seat 5 rises and the lower traction seat 5 falls. The two traction seats 5 move toward one end of the two threaded rods 4 connected to the limit seat 2. Therefore, the longitudinal distance between the traction seat 5 and the cross bar 7 will gradually decrease. The connecting arm 6 can gradually rotate at this time, and since the overall length of the connecting arm 6 cannot be changed, the connecting arm 6 will push the cross bar 7 to move in the direction away from the limit seat 2 when rotating, thereby realizing the distance adjustment between the frame body 1 and the limit seat 2.

[0031] The limiting seat 2 is also provided with an auxiliary heat dissipation structure, which includes a groove 10 and a heat dissipation slot 11 . The groove 10 and the heat dissipation slot 11 are arranged on both sides of the limiting seat 2 , and the heat dissipation slot 11 is connected to the groove 10 .

[0032] See also Figure 1 and 2 , when the two frame bodies 1 are Figure 1 When the two frame bodies 1 are connected in this way, the side of the frame body 1 is in contact with the side of the limit seat 2. At this time, part of the heat can enter the groove 10 through the heat dissipation groove 11 and finally dissipate the heat through the top of the groove 10. If the distance between the two frame bodies 1 is further increased, the frame body 1 will not be in contact with the side of the limit seat 2. At this time, a gap will appear between the frame body 1 and the limit seat 2, which further facilitates the heat dissipation of the frame body 1.

[0033] Embodiment 2:

[0034] The above scheme realizes the connection between the two frame bodies 1 through the connecting mechanism, and ensures the heat dissipation effect in cooperation with the limit seat 2 and the auxiliary heat dissipation structure. However, the connection strength is not high because the cross bars 7 on the two frame bodies 1 are connected together by only relying on the connecting arm 6 and the threaded rod 4. The connection may fall off due to bumps. Therefore, in this embodiment, a reinforcement structure is arranged between the threaded rod 4 and the cross bar 7. The reinforcement structure includes a diagonal support rod 13, a limit rod 14 and a slide groove 15. The slide groove 15 is arranged on the surface of the cross bar 7. A pair of diagonal support rods 13 are cross-rotated on the surface of each threaded rod 4. The two ends of the limit rod 14 are respectively slidably arranged in the two slide grooves 15 and fixed to one end of the diagonal support rod 13. The two diagonal support rods 13 on each threaded rod 4 are stacked together, and the threaded rod 4 is rotatably arranged at the center of the diagonal support rod 13 through a bearing.

[0035] See also Figure 2 and 3 The two stacked diagonal braces 13 can form a scissor structure. When the horizontal distance between the two cross bars 7 increases, the cross bar 7 can pull the limit rod 14 to move through the slide groove 15. The limit rod 14 can then pull the two ends of the diagonal brace rod 13, so that the two diagonal brace rods 13 rotate with the threaded rod 4 as the center. No matter how the cross bar 7 moves, the limit rod 14 can always follow the limit rod 14 through the slide groove 15 to move synchronously. Therefore, the limit rod 14, the cross bar 7, the diagonal brace rod 13, the connecting arm 6 and the threaded rod 4 can form a whole. In addition, a triangular stable structure can always be formed between the two diagonal braces 13 and the cross bar 7, and a triangular stable structure can also be approximately formed between the two connecting arms 6 on the same side and the frame body 1, thereby greatly increasing the connection strength between the two frame bodies 1, and thus being able to resist bumps and prevent the frame body 1 from being damaged.

[0036] Working principle: When in use, the handle 9 is used to drive the rotating shaft 8 to rotate, and the rotating shaft 8 can drive the threaded rod 4 to rotate unidirectionally through the mutual engagement of the two bevel gears 12, thereby making the two threaded rods 4 rotate synchronously, and each threaded rod 4 can drive the traction seat 5 to move linearly on its surface, and the movement mode of the two traction seats 5 is to approach or move away from each other, and since the cross bar 7 is fixed, the vertical distance between the traction seat 5 and the cross bar 7 will change during vertical movement, and the connecting arm 6 can gradually rotate at this time, and since the overall length of the connecting arm 6 cannot be changed, the connecting arm 6 will push the cross bar 7 to move in the direction away from the limit seat 2 or pull the cross bar 7 to move in the direction close to the limit seat 2 during rotation, and the change in the distance between the two cross bars 7 will cause the cross bar 7 to pull the limit rod 14 to move through the slide groove 15, and the limit rod 14 can now pull the two ends of the diagonal support rod 13, so that the two diagonal support rods 13 rotate with the threaded rod 4 as the center of the circle.
