Description

Technical Field

[0001] This utility model belongs to the field of cabinets and relates to a novel anti-door panel corner-dropping device. Background Technology

[0002] The cabinet consists of a cabinet body and doors. The doors are rotatably connected to the cabinet body and are used to open or close the cabinet. In existing technology, the doors are generally directly connected to the cabinet body via hinges. However, after the doors have been opened and closed for a long time, due to gravity and the weight of the doors themselves, the corners of the doors may chip, causing the doors to become stuck when opening and closing. Therefore, there is an urgent need to provide a solution. Summary of the Invention

[0003] In order to overcome at least one deficiency of the prior art, this utility model provides a novel anti-door panel corner-dropping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel anti-corner-dropping device for door panels, installed in a cabinet, the cabinet including a frame and a door panel hinged to the frame, the anti-corner-dropping device including an anti-corner-dropping movable device and an anti-corner-dropping fixed device, the anti-corner-dropping movable device being installed in the door panel, the anti-corner-dropping fixed device being installed in the frame, the anti-corner-dropping fixed device including a fixed surface and a movable surface, the anti-corner-dropping movable device including a roller, the roller making rolling contact with the fixed surface and the movable surface.

[0005] Furthermore, the fixed surface is horizontal, and the movable surface faces the door panel.

[0006] Furthermore, the movable surface and the fixed surface are fixedly connected, and the two are smoothly connected by a guide plate.

[0007] Furthermore, the anti-fall corner fixing device also includes a mounting plate, which is fixedly connected to the cabinet frame.

[0008] Furthermore, the fixing surface is fixedly connected to the mounting plate.

[0009] Furthermore, the movable surface is also fixedly connected to the mounting plate, and both sides of the movable surface are fixedly connected to the fixed surface and the fixed surface, respectively.

[0010] Furthermore, the anti-corner-dropping device also includes a corner-dropping bracket, which is fixedly connected to the door panel and movably connected to the roller.

[0011] Furthermore, the mounting plate is fixedly provided with a first connecting hole, the cabinet frame is provided with a second connecting hole, and fasteners pass through the connecting hole and the second connecting hole to fix the mounting plate and the cabinet frame in place.

[0012] Furthermore, the corner bracket is provided with a first mounting hole, and the door panel is provided with a second mounting hole. The first mounting hole and the second mounting hole correspond one-to-one, and the fastener passes through the first mounting hole and the second mounting hole to fix the corner bracket to the door panel.

[0013] Furthermore, the first mounting hole is an oblong hole.

[0014] In summary, the advantages of this utility model are as follows:

[0015] 1) When the door panel is closed, the roller rolls along the movable surface and guide plate to the fixed surface. At the same time as the door panel closes, the corner of the door panel is corrected by the corner-dropping device, and the door panel returns to the normal position. The anti-corner-dropping movable device supports the door panel through the fixed surface, reducing the probability of the door panel sagging or corner-dropping problems that may occur after long-term use.

[0016] 2) This utility model is provided with a fixed surface, a movable surface and a guide plate. The roller can roll along the guide plate to the fixed surface on the movable surface. Through the above structure, the existing corner-dropping solution fails and the door panel has great resistance to closing and is not smooth when the angle of the door panel drops too much. When the angle of the door panel drops too much, this application drives the roller to roll along the movable surface and the guide plate to the fixed surface in sequence to correct the corner drop and return the cornered door panel to the normal position. At the same time, the design of the roller can make the closing resistance small and the closing smooth. Attached Figure Description

[0025] Example 1:

[0026] like Figures 1-3 As shown, a novel anti-corner-dropping device for door panels is installed in a server rack. The server rack includes a rack frame 3 and a door panel 4 hinged to the rack frame 3. The anti-corner-dropping device includes an anti-corner-dropping movable device 1 and an anti-corner-dropping fixed device 2. The anti-corner-dropping movable device 1 is installed on the door panel 4, and the anti-corner-dropping fixed device 2 is installed on the rack frame 3. The anti-corner-dropping fixed device 2 includes a fixed surface 21 and a movable surface 22. The anti-corner-dropping movable device 1 includes a roller 11, which makes rolling contact with the fixed surface 21 and the movable surface 22.

[0027] The anti-fall corner fixing device 2 also includes a mounting plate 20, which is fixedly connected to the cabinet frame 3, thereby realizing the fixed connection between the anti-fall corner fixing device 2 and the cabinet frame 3.

[0028] The mounting plate 20 is fixedly provided with a first connecting hole 201, and the cabinet frame 3 is provided with a corresponding second connecting hole 31. Bolts, screws and other fasteners pass through the connecting holes 201 and the second connecting holes 31 and are threadedly connected to the cabinet frame 3. This structural design facilitates the disassembly, assembly and maintenance of the anti-fall corner fixing device 2 and the cabinet frame 3, and the connection between the anti-fall corner fixing device 2 and the cabinet frame 3 is firm. The number and distribution of the connecting holes 201 can be set as needed.

[0029] Preferably, the mounting plate 20 is located in the vertical direction, and the connection surface between the mounting plate 20 and the cabinet frame 3 is located in the vertical plane.

[0030] The fixed surface 21 is fixedly connected to the mounting plate 20. The fixed surface 21 is in the horizontal direction. The roller 11 rolls on the upper surface of the fixed surface 21. The fixed surface 21 supports the roller 11, thereby supporting the door panel 4. This reduces the probability of the door panel 4 sagging or corner falling off after long-term use, improves the working stability of the door panel 4, and extends the service life of the door panel 4.

[0031] The movable surface 22 is fixedly connected to the fixed surface 21. The movable surface 22 and the fixed surface 21 are inclined to facilitate the roller 11 to roll along the movable surface 22 towards the fixed surface 21. The movable surface 22 and the fixed surface 21 are smoothly connected by the guide plate 23, so that the roller 11 rolls from the movable surface 22 to the fixed surface 21 through the guide plate 23, thereby realizing the smooth reciprocating rolling of the roller 11 between the movable surface 22 and the fixed surface 21 during the opening and closing of the door panel 4.

[0032] Preferably, the movable surface 22 is also fixedly connected to the mounting plate 20, and both sides of the movable surface 22 are fixedly connected to the fixed surface 21 and the fixed surface 21 respectively, which effectively improves the stability of the movable surface 22.

[0033] like Figure 1 As shown, the mounting plate 20, the fixed surface 21, and the movable surface 22 are connected to form a cavity structure with three open sides. The connection surface between the mounting plate 20 and the cabinet frame 3 is located inside the cavity. That is, the position where the fasteners fix the mounting plate 20 and the cabinet frame 3 is located inside the cavity. This structural design accommodates the fasteners inside the cavity, avoiding injury to the user's hands and effectively improving safety.

[0034] The roller 11 rolls in contact with the fixed surface 21 and the movable surface 22. The roller 11 can roll along the surfaces of the fixed surface 21 and the movable surface 22 without damaging the fixed surface 21 and the movable surface 22. This not only makes the rotation of the door panel 4 relative to the cabinet frame 3 smooth and ensures the smoothness of opening and closing the door panel 4, but also provides support for the door panel 4, making it less likely to have problems such as sagging or corner breakage, thus extending the service life of the door panel 4. Preferably, the roller 11 can be set as a movable bearing.

[0035] The anti-drop corner device 1 also includes a corner-drop bracket 12, which is fixedly connected to the door panel 4 and movably connected to the roller 11.

[0036] The corner bracket 12 has a first mounting hole 123, and the door panel 4 has a second mounting hole (not shown in the figure). The first mounting hole 123 and the second mounting hole correspond one-to-one. Bolts, screws, and other fasteners pass through the first mounting hole 123 and the second mounting hole to thread the corner bracket 12 to the door panel 4. This structural design facilitates the disassembly, assembly, and maintenance of the anti-corner-dropping device 1 and the door panel 4, and the connection between the anti-corner-dropping device 1 and the door panel 4 is firm. The number and distribution of the first mounting holes 123 can be set as needed.

[0037] Preferably, the multiple first mounting holes 123 are arranged vertically. This structural design makes the connection between the corner bracket 12 and the door panel 4 more secure and less prone to loosening, which is beneficial for supporting the door panel 4.

[0038] Preferably, the first mounting hole 123 is an oblong hole, which facilitates the appropriate adjustment of the horizontal or vertical position of the corner bracket 12 on the door panel 4, ensuring that the roller 11 maintains rolling contact with the fixed surface 21, making it convenient and flexible to use.

[0039] Preferably, the corner bracket 12 is a bent structure, including a first bracket 121 and a second bracket 122 connected vertically. The first bracket 121 and the second bracket 122 are in the vertical direction. The second bracket 122 is close to the door panel 4 and fixedly connected to the door panel 4. The first mounting hole 123 is provided in the second bracket 122. The roller 11 is movably connected to the first bracket 121.

[0040] The implementation process is as follows:

[0041] When the door panel 4 rotates relative to the cabinet frame 3 to open the cabinet frame 3, the roller 11 rolls sequentially along the fixed surface 21, the guide plate 23, and the movable surface 22 until the roller 11 is completely disengaged from the anti-drop corner fixing device 2, and the door panel 4 is fully opened. When the door panel 4 closes, if the drop angle is small, the roller 11 rolls along the inclined guide plate 23 to the fixed surface 2, and the door panel 4 closes while the drop angle is corrected by the anti-drop corner device. If the drop angle is large, the roller 11 rolls into contact with the movable surface 22. As the door panel 4 continues to close, under the closing force of the door panel 4, the roller 11 rolls along the inclined guide plate 23 to the fixed surface 2, and the door panel 4 closes while the drop angle is corrected by the anti-drop corner device, and the door panel 4 returns to its normal position. During this process, the anti-drop corner fixing device 2 is activated. The corner-dropping device 1 supports the door panel 4 via the fixed surface 21, reducing the probability of the door panel 4 sagging or corner-dropping problems due to long-term use. In addition, this application adds a movable surface 22 to the guide plate 23 to extend the rolling path, so that the roller 11 can roll from the movable surface 22 along the guide plate 23 to the fixed surface 21. Through the above structure, the problem of existing corner-dropping solutions failing when the door panel drops at a large angle and the door panel closing resistance being high and not closing smoothly is effectively solved. When the door panel drops at a large angle, this application drives the roller 11 to roll sequentially along the movable surface 22 and the guide plate 23 to the fixed surface 2 to correct the corner drop and return the door panel with the corner drop to the normal position. At the same time, the design of the roller 11 can make the closing resistance small and the closing smooth.

[0042] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
