Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to an active sealing type switch cabinet door body structure. Background Technique

[0002] After the switch cabinet operates for a period of time, the joint between the cabinet door and the cabinet body will be poorly sealed, and moisture or dust will enter the interior of the switch cabinet, affecting the normal operation of the mechanism. If the surrounding environment has a high humidity, "condensation" will form inside the switch cabinet, and the insulation strength inside the cabinet will also be reduced under humid conditions, bringing huge potential safety hazards such as pollution flashover.

[0003] Most switch cabinets are provided with gaskets at the joints between the cabinet doors and the cabinet bodies. When the cabinet doors are closed, the gaskets will be squeezed to ensure the sealing performance. However, when the cabinet doors are repeatedly opened and closed for a long time, the repeated squeezing actions are likely to cause damage to the gaskets, resulting in loose closing of the subsequent cabinet doors with gaps, and it is impossible to actively seal and adjust the gaskets further. Content of the Utility Model

[0004] The purpose of the utility model is to provide an active sealing type switch cabinet door body structure to solve the above technical problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-5 shown, an actively sealed switch cabinet door body structure includes a cabinet body 1 and a cabinet door 2 hinged outside the cabinet body 1. A first fixing frame 3 is fixedly arranged inside the cabinet body 1, a sealing plate 4 is slidably arranged inside the cabinet door 2, and a driving assembly for driving the sealing plate 4 to closely fit the outer surface of the first fixing frame 3 is arranged inside the cabinet door 2.

[0027] Furthermore, the driving assembly includes a bidirectional lead screw 6 rotatably arranged inside the cabinet door 2 and two connecting seats 15 symmetrically arranged on one side of the sealing plate 4. An operating handle 7 for driving the bidirectional lead screw 6 to rotate is rotatably arranged outside the cabinet door 2. Two threaded seats 9 are symmetrically threadedly sleeved on the outside of the bidirectional lead screw 6. Two connecting rods 10 are respectively hinged on the outside of the two threaded seats 9. One ends of the two connecting rods 10 are respectively hinged and matched with the two connecting seats 15. During use, first, the staff closes the cabinet door 2, and then rotates the operating handle 7 to drive the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 drives the two threaded seats 15 to move relatively. Under the action of the connecting rod 10, the sealing plate 4 moves towards the first fixing frame 3 until the sealing plate 4 is in close contact with the outer surface of the first fixing frame 3, effectively ensuring the sealing performance inside the cabinet body 1 after the cabinet door 2 is closed.

[0028] Furthermore, a second fixing frame 8 is fixedly arranged inside the cabinet door 2. Two installation grooves are symmetrically formed on one side of the second fixing frame 8 close to the sealing plate 4. Constraint blocks 11 that cooperate with the inner wall of the cabinet body 1 are slidably arranged inside the two installation grooves. Both of the two constraint blocks 11 are connected to the inner wall of the installation groove through springs 12. During use, first, the sealing plate 4 moves towards the first fixing frame 3. During this process, the sealing plate 4 moves away from the second fixing frame 8, gradually relieving the extrusion on the constraint blocks 11. The constraint blocks 11 pop outwards under the action of the springs 12 and come into contact with the inner wall of the cabinet body 1. When the constraint blocks 11 are in contact with the inner wall of the cabinet body 1, the flipping and opening of the cabinet door 2 are restricted, that is, the stability of the closed state of the cabinet door 2 is ensured.

[0029] Furthermore, a protective shell 5 for pressing the outer surface of the operating handle 7 is hinged on the outer side of the cabinet door 2. One side of the protective shell 5 away from the hinge is fixedly connected to the outer surface of the cabinet door 2 through bolts. After the operating handle 7 is rotated, the staff closes the protective shell 5, so that the protective shell 5 tightly presses on the outer surface of the operating handle 7, effectively restricting the rotation of the operating handle 7.

[0030] Furthermore, a first sealing gasket 13 that cooperates with the first fixing frame 3 is arranged on one side of the sealing plate 4, and a second sealing gasket 14 that cooperates with the second fixing frame 8 is arranged on the other side of the sealing plate 4. By providing the first sealing gasket 13 and the second sealing gasket 14, the sealing performance of the contact surface of the sealing plate 4 is further ensured.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
