Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, and in particular to a blind plate structure and cabinet. Background Technology

[0002] Server rack blind panels can insulate the front and back of the server rack from cold and hot air, thus creating a better cooling channel inside the rack and providing a better cooling environment for the operating equipment. Without server rack blind panels, the front and back of the rack cannot be insulated from cold and hot air. When the air inlet temperature is too high, the fans inside the equipment will draw the heat from the air inlet into the rack, reducing cooling efficiency.

[0003] Existing cabinet blind flanges use a gear transmission structure to open and close, which is not convenient to operate and requires staff to manually rotate the handle, resulting in low work efficiency. Utility Model Content

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1-3As shown, this utility model provides a blind flange structure for heat insulation and heat dissipation of equipment inside a server rack. The blind flange structure includes a winding shaft 1, a blind flange 2, an elastic element 3, a movable beam 4, and two locking elements 5. The winding shaft 1 is rotatably mounted at the opening of the server rack around its own axis. One end of the blind flange 2 is fixed, and the other end is movable; the fixed end is fixedly connected to the winding shaft 1. One end of the elastic element 3 is connected to the blind flange 2, and the other end is fixedly mounted relative to the inner wall of the server rack. The movable beam 4 is fixedly mounted at the movable end and is parallel to the winding shaft 1. The two locking elements 5 are correspondingly and detachably mounted at both ends of the movable beam 4. Each locking element 5 includes a locking clip 51, which can lock onto the side wall of the opening of the server rack. When the locking clip 51 is separated from the side wall of the server rack, the blind flange 2 can be wound onto the winding shaft 1 under the elastic restoring force of the elastic element 3.

[0038] When the blind plate 2 needs to be unfolded to block the cabinet opening, pull the movable beam 4 so that the movable end of the blind plate 2 is away from the fixed end. Connect the two locking pieces 5 one-to-one to the two ends of the movable beam 4, and lock the locking clip 51 to the side wall at the cabinet opening. When the blind plate 2 needs to be retracted, simply unlock the locking clip 51 to the side wall of the cabinet, and the blind plate 2 can be rolled up onto the winding shaft 1 under the elastic restoring force of the elastic piece 3. The operation is simple and convenient, the structure is highly versatile, and it can be adapted to various cabinet models.

[0039] Specifically, the blind flange structure also includes a fixing frame 6, which includes a fixing beam 61. The fixing beam 61 is detachably installed at the opening of the cabinet, and a connecting part 611 is fixedly installed at both ends of the fixing beam 61. The two ends of the winding shaft 1 are rotatably connected to the two connecting parts 611 respectively. The above configuration enables the winding shaft 1 to be rotated relative to the cabinet opening, and the structure is simple, reliable, and highly stable.

[0040] More specifically, the mounting bracket 6 also includes a transition bearing 62, one of which, the inner ring and the outer ring, is fixedly connected to the transition part 611, and the other is fixedly connected to the take-up shaft 1. The aforementioned transition bearing 62 enables a rotatable connection between the transition part 611 and the end of the take-up shaft 1, and is low in production cost and not easily damaged.

[0041] Specifically, the mounting bracket 6 also includes a fixing block 63, which is slidably connected to the fixing beam 61. One side of the fixing block 63 can be locked to the fixing beam 61, and the other side can be detachably connected to the inner wall of the cabinet. With the above configuration, the position of the fixing block 63 in the length direction of the fixing beam 61 is adjustable, so that the fixing beam 61 can be adapted to cabinets of different structures and models.

[0042] In this embodiment, for example, the fixing block 63 can be locked to the fixing beam 61 by a bolt and nut structure. In other embodiments, the fixing block 63 can also be bonded to the fixing beam 61 by adhesives commonly used in the art.

[0043] Specifically, the locking component 5 also includes a latch 52, which is fixedly connected to the locking clip 51. Both ends of the movable beam 4 are provided with slots, and the latch 52 is configured to extend into the slots and press against the inner wall of the slots. With the above arrangement, the latch 52 and the slots cooperate with each other to achieve a detachable connection between the locking component 5 and the movable beam 4.

[0044] More specifically, the locking clip 51 is provided with a fixed part 511 and a movable part 512, which can magnetically attract each other. With the above configuration, when the locking clip 51 needs to be clamped at the opening of the cabinet, the fixed part 511 is located on the inner wall of the cabinet, and the movable part 512 is located on the outer wall of the cabinet. The two are magnetically attracted and fixed to each other to fix the locking clip 51 at the opening of the cabinet. When the side wall of the cabinet is thick, the locking clip 51 can also be magnetically locked to the side wall of the cabinet, which is highly versatile.

[0045] In other embodiments, the locking clip 51 can also be a spring clip structure commonly used in the art, the working principle and specific structure of which will not be described in detail here.

[0046] For example, in this embodiment, the elastic element 3 is configured as a torsion spring. The elastic element 3 is sleeved on the take-up shaft 1, with one end fixedly connected to the inner wall of the cabinet and the other end fixedly connected to the take-up shaft 1. With the above-mentioned torsion spring, the torsion spring can be sleeved on the take-up shaft 1 along the length direction of the take-up shaft 1, which saves space and is more aesthetically pleasing. However, when replacing the torsion spring, the take-up shaft 1 needs to be disassembled.

[0047] Alternatively, in other embodiments, the elastic element 3 is configured as a spring, with one end connected to the fixed end of the blind plate 2 and the other end connected to the inner wall of the cabinet. This spring configuration allows for spring replacement without disassembling the winding shaft 1, making operation simple and convenient.

[0048] This utility model also provides a cabinet, including a cabinet body and the aforementioned blind panel structure. It is understood that this cabinet possesses all the beneficial effects of the aforementioned blind panel structure, which will not be elaborated upon here.

[0049] Specifically, the cabinet is equipped with multiple accommodating cavities, each with a blind plate structure. This arrangement of accommodating cavities allows the cabinet to simultaneously accommodate multiple electronic communication devices, thereby improving the cabinet's space utilization.

[0050] For example, in this embodiment, multiple partitions are arranged vertically inside the cabinet to separate multiple accommodating cavities, and a blind plate structure is provided between two adjacent partitions. The movable end of the blind plate 2 can be unfolded horizontally to block the opening of the accommodating cavity.

[0051] Alternatively, in other embodiments, the cabinet can be adjusted to have multiple compartments spaced apart in the horizontal direction, so that the accommodating cavities are also spaced apart in the horizontal direction, according to actual usage requirements. No specific limitation is made here.

[0052] Alternatively, in other embodiments, the movable end of the blind plate 2 can also be adjusted to unfold in the vertical direction, without being specifically limited here.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
