Description

Technical Field

[0001] The utility model relates to the field of communication cabinets, in particular to a heat dissipation structure used for a communication cabinet. Background Art

[0002] The communication cabinet is made of metal or non-metal materials and does not allow unauthorized operators to enter and operate the cabinet. It provides a physical working environment and security system for wireless communication sites or wired network site workstations.

[0003] Publication No.: CN218163208U discloses a communication cabinet for a fire passage, which is used as a spare communication cabinet. In order to solve the problem that the communication cabinet is kept sealed when not in use to avoid dust accumulation and can dissipate heat when not sealed when in use, a cabinet body, a cabinet top and a cabinet door are provided, the cabinet top is located at the upper end surface of the cabinet body and the cabinet top is fixedly connected to the cabinet body, the cabinet door is located at the front end surface of the cabinet body, the front and rear sides of the cabinet top are provided with heat dissipation holes, the cabinet door is provided with a glass window, the left and right sides of the inner side of the cabinet body are symmetrically provided with a track shaft 1, the tail of the track shaft 1 is fixedly connected with an adjustment block, the upper part of the track shaft 1 is provided with a track shaft 2, the track shaft 2 is fixedly connected with a spur gear, and a heat dissipation adjustment structure is provided between the cabinet top and the spur gear. When not in use, it is necessary to ensure the sealing of the communication cabinet, and the heat dissipation holes are blocked by a sealing plate to prevent dust from falling into them and making the instruments inside unusable.

[0004] In short, in the above-mentioned prior art, knobs (adjustment blocks) are set on both sides of the cabinet, and the knobs control the rotation of the gears through the belt body. The gears engage with the rack plate fixed under the sealing plate to control the sliding of the sealing plate, so that the heat dissipation holes on the top of the cabinet are unobstructed. However, in the above-mentioned structure, when it is actually used, if only one side of the knob is rotated, not only will the force point be single when the sealing plate slides, but the gear on the other side will also block the movement of the tooth plate on the corresponding side of the sealing plate. Therefore, in order to ensure the stability of the sealing plate when sliding and avoid getting stuck when sliding, it is ideally necessary to rotate the knobs at the same speed on both sides of the cabinet at the same time. In order to make the process of controlling the opening and closing of the heat dissipation holes of the communication cabinet more convenient, we propose a heat dissipation structure for the communication cabinet.

At this time, the movable column 7 controls the sealing plate 3 to lift up through the horizontal plate 6 fixed on its outside, thereby closing the heat dissipation groove 2.

[0023] Among them, the control component 5 includes a pull-up mechanism 10 and a pull-down mechanism 11, the pull-up mechanism 10 includes a back column 12, the back column 12 is fixedly connected to the top of the cabinet 1, and a first positioning block 13 is fixedly connected to the top of the cabinet 1 near the edge. A first pulling wire 14 is slidably connected between the back column 12 and the first positioning block 13. One end of the first pulling wire 14 is fixedly connected to the top of the movable column 7, and the other end of the first pulling wire 14 passes through the first positioning block 13 and hangs down to the outside of the cabinet 1. It can be understood that Figure 1 From a certain perspective, when the first pulling wire 14 is pulled downward from the right side of the cabinet 1, the movable column 7 can be lifted up by pulling the first pulling wire 14 from the lower end of the back column 12. When the sealing plate 3 is not in contact with the heat dissipation slot 2, the sealing plate 3 can be controlled to lift up to close the heat dissipation slot 2.

[0024] It can be understood that the pull-down mechanism 11 includes a front column 15, which is fixedly connected to the top of the cabinet 1, and a through vertical groove 16 is opened on the surface of the front column 15. The outer wall of the movable column 7 is fixedly connected with a convex column 17 that matches the size of the vertical groove 16, and the convex column 17 is slidably connected to the inside of the vertical groove 16 through the movable column 7.
