Description

Technical Field

[0001] This utility model relates to the field of communication cabinets, and in particular to magnetic double-locking quick-release blind plates. Background Technology

[0002] A blind flange is an accessory in a computer cabinet, available in 1U, 2U, and 3U sizes. Installed in the cabinet, it fills in unused U-positions, improving the cabinet's appearance. Furthermore, by blocking these gaps, it creates a closed, bottom-up cold aisle within the cabinet, improving cooling efficiency for the equipment. Additionally, many devices installed in the cabinet are electrically connected; blind flanges prevent customers from touching exposed conductors, enhancing safety and facilitating cleaning of the equipment.

[0003] Traditional communication cabinet blind plates are generally fixed with bolts or screws. During installation, tools are needed to align and tighten multiple bolts one by one. During disassembly, they also need to be loosened one by one. The operation steps are cumbersome, and a single disassembly and assembly can take several minutes. Bolt fixing requires specific wrenches or screwdrivers. If the tools are lost or the model is incompatible, it may lead to operation interruption or even stripping and damage of the bolts, increasing maintenance costs. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a magnetic double-locking quick-release blind plate, which can effectively solve the technical problem of inconvenient disassembly and assembly caused by installation with bolts to the cabinet.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A magnetic double-locking quick-release blind plate includes a mounting plate, a first mounting base, and a second mounting base. The two ends of the mounting plate are detachably connected to the first mounting base and the second mounting base, respectively. The first mounting base and the second mounting base are used to fix the blind plate in a communication cabinet. The two ends of the mounting plate are respectively provided with a first positioning part and a second positioning part. The surface of the first mounting base is provided with a rotatable positioning sleeve. The first positioning part can be paired and inserted into the positioning sleeve. The positioning sleeve and the first positioning part are provided with mutually attractive magnetic blocks.

[0007] The second positioning part includes a housing, a latch, a connecting rod, and an unlocking button. The latch, connecting rod, and unlocking button are installed inside the housing. The side wall of the housing is fixedly connected to the mounting plate. The latch and unlocking button are located at both ends of the connecting rod. The bottom surface of the housing is provided with a positioning groove. The latch extends into the positioning groove, and the unlocking button extends to the side wall of the housing. The surface of the connecting rod is connected to the inner wall of the housing through an elastic connector. The unlocking button can drive the latch to extend and retract through the connecting rod. The surface of the second mounting base is provided with a positioning block. The side wall of the positioning block is provided with a tongue hole, and the latch can be paired and inserted into the tongue hole.

[0008] Furthermore, a sliding sleeve is provided inside the outer casing, and both ends of the connecting rod pass through the sliding sleeve. The elastic connecting element is a compression spring, which is sleeved on the surface of the connecting rod. A baffle is provided at one end of the connecting rod, and both ends of the compression spring abut against the baffle and the sliding sleeve, respectively.

[0009] Furthermore, the surface of the second mounting base is provided with a compressible elastic pad, and the surface of the elastic pad is provided with anti-slip texture.

[0010] Furthermore, an elastic connector is also provided between the unlock button and the inner wall of the housing, the unlock button is movably connected to one end of the connecting rod, and the latch is fixedly connected to one end of the connecting rod.

[0011] Furthermore, the surface of the mounting plate is provided with anti-slip pads and reinforcing ribs.

[0012] Furthermore, a torsion spring is provided between the first mounting base and the positioning sleeve, and a positioning protrusion is provided on the surface of the first mounting base.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: It achieves efficient assembly and disassembly through a dual locking mechanism of magnetic attraction and latch. The first positioning part and the positioning sleeve are automatically attracted by the built-in magnetic block, allowing for quick initial fixation without precise alignment during installation, significantly shortening positioning time. The magnetic attraction provides a stable pre-fixation effect, preventing accidental detachment of the mounting plate. The latch of the second positioning part cooperates with the tongue hole to form a rigid lock, combined with the restoring force of the elastic connector, ensuring a tight fit between the mounting plate and the cabinet, preventing loosening due to vibration during equipment operation. Pressing the unlock button directly controls the latch retraction via a linkage, allowing for unlocking with one hand without tool assistance. After unlocking, flipping the mounting plate separates the magnetic end, simplifying operation and making it particularly suitable for high-frequency maintenance or emergency repair scenarios. The collaborative design of the magnetic attraction and latch completely eliminates the traditional bolt or screw fixing method, eliminating the need for tools during assembly and disassembly, avoiding delays caused by lost or mismatched tools. Maintenance personnel can quickly replace blind flanges or access the inside of the cabinet, improving maintenance efficiency. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is combined Figures 1-4 The present invention provides a detailed description of the magnetic double-locking quick-release blind flange:

[0021] A magnetic double-locking quick-release blind flange includes a mounting plate 1, a first mounting base 2, and a second mounting base 3. The two ends of the mounting plate 1 are detachably connected to the first mounting base 2 and the second mounting base 3, respectively. The first mounting base 2 and the second mounting base 3 are used to fix the flange inside a communication cabinet. The two ends of the mounting plate 1 are respectively provided with a first positioning part 4 and a second positioning part 5. The surface of the first mounting base 2 is provided with a rotatable positioning sleeve 6. The first positioning part 4 can be paired and inserted into the positioning sleeve 6. The positioning sleeve 6 and the first positioning part 4 are provided with mutually attractive magnetic blocks 7.

[0022] The second positioning part 5 includes a housing 501, a latch 502, a connecting rod 503, and an unlocking button 504. The latch 502, connecting rod 503, and unlocking button 504 are installed inside the housing 501. The side wall of the housing 501 is fixedly connected to the mounting plate 1. The latch 502 and unlocking button 504 are located at both ends of the connecting rod 503. The bottom surface of the housing 501 is provided with a positioning groove 505. The latch 502 extends into the positioning groove 505, and the unlocking button 504 extends into the side wall of the housing 501. The surface of the connecting rod 503 is connected to the inner wall of the housing 501 through an elastic connector. The unlocking button 504 can drive the latch 502 to extend and retract through the connecting rod 503. The surface of the second mounting base 3 is provided with a positioning block. The side wall of the positioning block is provided with a tongue hole 301. The latch 502 can be paired and inserted into the tongue hole 301.

[0023] Installation process: First, fix the first mounting base 2 and the second mounting base 3 in the cabinet. Place the mounting plate 1 into the cabinet at an angle. Insert the first positioning part 4 into the positioning sleeve 6. The positioning sleeve 6 and the first positioning part 4 are attracted to each other by the magnetic block 7. Flip the mounting plate 1 and engage the second positioning part 5 with the second mounting base 3. Insert the latch 502 into the latch hole 301.

[0024] Disassembly process: Press the unlock button 504 to retract the latch 502 into the outer shell 501 and separate it from the latch hole 301. After flipping the mounting plate 1, pull the first positioning part 4 out of the positioning sleeve 6.

[0025] The beneficial effects are as follows: Efficient assembly and disassembly are achieved through a dual locking mechanism of magnetic attraction and latch 502. The first positioning part 4 and the positioning sleeve 6 are automatically attracted by the built-in magnetic block 7, allowing for quick initial fixation without precise alignment during installation, significantly shortening positioning time. The magnetic attraction provides a stable pre-fixation effect, preventing the mounting plate 1 from accidentally falling off. The latch 502 of the second positioning part 5 cooperates with the tongue hole 301 to form a rigid lock. Combined with the restoring force of the elastic connector, this ensures that the mounting plate 1 fits tightly against the cabinet, preventing loosening due to vibration during equipment operation. Pressing the unlock button 504 directly controls the latch 502 to retract via the linkage 503, allowing for unlocking with one hand without tool assistance. After unlocking, flipping the mounting plate 1 separates the magnetic end, making operation simple and particularly suitable for high-frequency maintenance or emergency repair scenarios. The collaborative design of the magnetic attraction and latch 502 completely eliminates the traditional bolt or screw fixing method, eliminating the need for tools during assembly and disassembly, avoiding delays caused by lost or mismatched tools. Maintenance personnel can quickly replace blind flanges or access the inside of the cabinet, improving maintenance efficiency.

[0026] A sliding sleeve 506 is provided inside the outer casing 501. Both ends of the connecting rod 503 pass through the sliding sleeve 506. The elastic connecting element is a compression spring 507, which is sleeved on the surface of the connecting rod 503. A baffle is provided at one end of the connecting rod 503. Both ends of the compression spring 507 abut against the baffle and the sliding sleeve 506 respectively. The two ends of the connecting rod 503 are guided by the sliding sleeve 506. Combined with the elastic return of the compression spring 507, this ensures the linear and precise extension and retraction of the latch 502, eliminating jamming problems caused by lateral offset. The abutment design between the baffle and the sliding sleeve 506 limits the spring compression stroke, preventing excessive deformation and extending the service life of the elastic connecting element.

[0027] The surface of the second mounting base 3 is provided with a compressible elastic pad 8, and the surface of the elastic pad 8 is provided with anti-slip texture. The elastic pad 8 on the surface of the second mounting base 3 is deformed under pressure when the latch 502 is locked, providing additional cushioning and increasing friction, further suppressing vibration transmission and preventing abnormal noise or micro-displacement between the blind plate and the cabinet. An elastic connector is also provided between the unlock button 504 and the inner wall of the outer shell 501. The unlock button 504 is movably connected to one end of the connecting rod 503, and the latch 502 is fixedly connected to one end of the connecting rod 503, ensuring that the button automatically resets to the initial position after being pressed. During installation, the retraction of the latch 502 will not cause the unlock button 504 to retract synchronously.

[0028] The surface of the mounting plate 1 is provided with anti-slip pads and reinforcing ribs. The anti-slip pads on the surface of the mounting plate 1 increase grip friction and prevent hand slippage during disassembly. The reinforcing ribs reduce weight while increasing bending stiffness, preventing the mounting plate 1 from deforming due to external pressure and ensuring the flatness of the blind plate for long-term use.

[0029] A torsion spring is provided between the first mounting base 2 and the positioning sleeve 6. The surface of the first mounting base 2 is provided with a positioning protrusion 201. When disassembling, the positioning sleeve 6 automatically rotates upward to facilitate quick alignment during the next installation. The positioning protrusion 201 limits the maximum upward rotation range of the positioning sleeve 6.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
