Description

Technical Field

[0001] This invention belongs to the field of cabinet bracket technology, and particularly relates to a self-locking cabinet with adjustable brackets. Background Technology

[0002] Currently, traditional server rack brackets on the market are formed by bending sheet metal, such as... Figure 1-3 As shown, the conventional bracket 1 has a bent back plate 2 and a tray 3. The back plate 2 is used to connect to the frame 4, and the tray 3 is used to support the equipment. The frame 4 has square holes 5. The conventional bracket 1 is fastened to the frame 4 of the cabinet with screws, flat spring washers and combination square nuts, and the layout follows the 19-inch standard layout.

[0003] Traditional rack bracket installation has several drawbacks: First, fasteners are required to secure the bracket to the rack frame, making installation and disassembly cumbersome. This wastes significant manpower, resources, and time. Adjusting the bracket order on-site further increases the workload. Second, traditional rack brackets only support equipment. When dealing with equipment with simultaneous front and rear cabling, there's no way to secure the cables extending from the front to the rear cable trays, as the cable trays are located at the rear. Without a connection between the front and rear, cables are not properly secured, potentially causing damage. Furthermore, exposed cables on the rack sides detract from the overall aesthetics. Third, traditional rack brackets use a backplate bent at an angle without additional reinforcement. Since the trays support equipment, which has weight, heavy equipment can deform the brackets, potentially causing the equipment to sink and deform. Additionally, loading and unloading equipment causes wear and tear on the trays. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a self-locking bracket adjustable type cabinet. By setting a self-locking hook on the bracket and cooperating with the irregular slot on the frame, the bracket and the frame are connected without fasteners, so as to facilitate disassembly and assembly.

[0005] To achieve the above objectives, the main technical solutions adopted by the present invention include: An adjustable self-locking cabinet includes a bracket, a first frame, and a second frame. The bracket has a first plate and a second plate that are perpendicular to each other. The first plate has a self-locking hook that is positioned towards the frame. The first and second frames have irregularly shaped slots at positions corresponding to the self-locking hooks. The self-locking hook includes a bent portion and a protruding engaging portion. The bent portion bends downwards towards the frame, and the protruding engaging portion is laterally perpendicular to the bent portion. The irregularly shaped slot includes a first side, a second side, a first groove, a second groove, a third side, and a bottom. The first side and the top side are arranged opposite to the second side, the first groove, the second groove, and the third side, which are continuously arranged on one side. The distance between the first side and the second side is less than the width of the protruding engagement part and greater than the width of the bent part. The distance between the first side and the side of the first groove is greater than the width of the protruding engagement part. The distance between the first side and the side of the second groove is less than the width of the protruding engagement part and greater than the width of the bent part. The distance between the first side and the third side is less than the width of the protruding engagement part, and from top to bottom, the distance increases from greater than the width of the bent part to the width of the bent part.

[0006] Furthermore, the bending portion bends 90° from the horizontal to the vertical direction and then bends towards the first plate, so that the self-locking hook hangs on the frame and abuts tightly against the frame.

[0007] Furthermore, the bottom of the bent portion is provided with a positioning groove, and the bottom edge of the irregularly shaped slot is provided with a positioning protrusion that matches the positioning groove. The positioning groove and the positioning protrusion are used to limit the self-locking hook.

[0008] Furthermore, the first plate is provided with a card plate extending towards the frame, and the frame is provided with a card plate groove at the corresponding position of the card plate, which is used to limit the upper and lower positions of the card plate, thereby limiting the upper and lower directions of the bracket.

[0009] Furthermore, a cable fixing groove is provided on the side of the first plate facing away from the frame.

[0010] Furthermore, a number of reinforcing ribs are provided at the inner corner of the bend between the first plate and the second plate, and the reinforcing ribs are used to strengthen and fix the bend position between the first plate and the second plate.

[0011] Furthermore, the second plate is provided with a self-locking hook, which has the same structure as the self-locking hook on the first plate and is located at the position corresponding to the irregular slot when the second plate is hung on the frame; the second plate is provided with a card plate, which is located at the position corresponding to the card plate slot when the second plate is hung on the frame, and the card plate slot is positioned above and below the card plate of the second plate.

[0012] Furthermore, the width of the edge of the first plate away from the connection point between the first plate and the second plate is less than the width of the edge of the second plate away from the connection point. When the first plate is hung on the frame, the distance between the second plates of a pair of brackets at the same height of the frame is less than the width of the equipment to be supported. When the second plate is hung on the frame, the distance between the first plates of a pair of brackets at the same height of the frame is greater than the width of the equipment to be supported.

[0013] Furthermore, the second plate is provided with anti-slip grooves at the equipment support position, and anti-slip mats are provided in the anti-slip grooves.

[0014] Furthermore, the self-locking hook, clamping plate, cable fixing groove, reinforcing rib, and anti-slip groove are formed by stamping the first plate and the second plate into one piece.

[0015] The beneficial effects of this invention are: 1. This invention achieves a fastener-free connection between the bracket and the frame by setting a self-locking hook on the first plate and a special-shaped slot on the frame, which is convenient for disassembly and assembly, saves manpower and costs; 2. The self-locking hook cooperates with the irregular groove on the frame to achieve lateral limitation, and the card plate cooperates with the card plate groove on the frame to achieve vertical limitation of the bracket; 3. This invention constrains cables by setting cable fixing grooves on the first plate, making the wiring inside the cabinet neat and protecting the cables from damage. 4. By also setting the same self-locking hooks and locking plates on the second plate, the bracket can be adjusted in the frame position using the second plate, which facilitates the adjustment and positioning of the bracket. 5. By setting reinforcing ribs between the first and second plates, the support strength of the bracket is increased, preventing the bracket from deforming or being damaged; 6. By setting anti-slip grooves on the bracket and using anti-slip mats, the tray can prevent the equipment it supports from slipping, thus reducing wear between the tray and the equipment.

Detailed Implementation

[0018] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This invention provides a self-locking cabinet with adjustable brackets, such as... Figure 4-12 As shown, it includes a bracket 6, a first frame 17, and a second frame 20. The bracket 6 has a first plate 7 and a second plate 8 that are perpendicular to each other, specifically arranged in an L-shape. Figure 4-5 As shown, the first plate 7 is provided with self-locking hooks 9 arranged towards the frame. Specifically, four hooks can be provided: two upper and two lower hooks 9 at the connection position with the first frame 17, and two upper and two lower hooks 9 at the connection position with the second frame 20. This ensures the stability of the bracket hanging on the frame. The first frame 17 and the second frame 20 are provided with irregularly shaped slots 18 at positions corresponding to the self-locking hooks 9. These slots cooperate with the self-locking hooks 9, allowing the self-locking hooks 9 to self-lock after entering the irregularly shaped slots 18 at specific positions, and to separate from the irregularly shaped slots 18 at specific positions, achieving a fastener-free connection and facilitating assembly and disassembly.

[0020] like Figure 6As shown, the self-locking hook 9 includes a bent portion 9-1 and a protruding engaging portion 9-2. The bent portion 9-1 bends downwards towards the frame, and the protruding engaging portion 9-2 is horizontally perpendicular to the bent portion 9-1. The bent portion 9-1 allows the self-locking hook 9 to be hooked into the irregularly shaped slot 18 of the frame. Specifically, the bent portion 9-1 bends 90° from horizontal to vertical and then slightly bends towards the first plate 7 at a certain angle, approximately 5°, so that the self-locking hook 9 is tightly abutted against the frame after being hooked. More specifically, the bottom side of the bent portion 9-1 facing the frame can be arc-shaped to facilitate a smoother entry of the self-locking hook 9 into the irregularly shaped slot 18.

[0021] like Figure 8-10 As shown, the irregularly shaped slot 18 includes a first side 18-1, a top edge 18-8, a second side 18-2, a first groove 18-3, a second groove 18-4, a third side 18-5, and a bottom edge 18-6 connected end to end. The first side 18-1 is positioned opposite to the second side 18-2, the first groove 18-3, the second groove 18-4, and the third side 18-5, which are continuously arranged on one side. The lateral distance D between the first side 18-1 and the second side 18-2 is less than the width a of the protruding engaging portion 9-2 and greater than the width c of the bent portion 9-1, preventing the self-locking hook 9 from sliding out between the first side 18-1 and the second side 18-2. The lateral distance A between the first side 18-1 and the side of the first groove 18-3 is greater than the width a of the protruding engaging portion 9-2, allowing the self-locking hook 9 to enter and exit the irregularly shaped slot 18 at this location. The lateral distance B between the first side 18-1 and the second groove 18-4 is less than the width a of the protruding engaging portion 9-2 and greater than the width c of the bent portion 9-1, preventing the self-locking hook 9 from disengaging from the irregular groove 18 at this point and causing it to transition downwards. The lateral distance C between the first side 18-1 and the third side 18-5 is less than the width a of the protruding engaging portion 9-2 and moves from top to bottom from being greater than the width of the bent portion 9-1 to approaching the width c of the bent portion 9-1, ultimately engaging and limiting the self-locking hook 9. Specifically, the bottom of the bent portion 9-1 is provided with a positioning groove 9-3, and the bottom edge 18-6 of the irregular groove 18 is provided with a positioning protrusion 18-7 that matches the positioning groove 9-3. The positioning groove 9-3 and the positioning protrusion 18-7 are used to limit the self-locking hook 9, thereby achieving lateral limitation of the self-locking hook 9.

[0022] Specifically, the first plate 7 is provided with a retaining plate extending towards the frame. The frame has a retaining plate groove at the corresponding position of the retaining plate, which is used to limit the upper and lower movement of the retaining plate, and thus limit the upper and lower movement of the bracket 6, that is, the longitudinal movement. More specifically, the first plate 7 is provided with two retaining plates, namely a first retaining plate 10 and a second retaining plate 11, which are respectively matched with the first retaining groove 10 on the first frame 17 and the second retaining groove 21 on the second frame 20. The edges of the retaining plates entering and exiting the retaining grooves can be provided with arc chamfers to facilitate smoother movement of the retaining plates in and out of the retaining grooves.

[0023] The self-locking hook 9 and the irregularly shaped slot 18 provide lateral positioning, while the card plate and the card plate slot provide longitudinal positioning, making the bracket 6 more securely assembled on the frame.

[0024] Specifically, the first plate 7 has a cable fixing groove 15 on the side facing away from the frame. The cable fixing groove 15 can be set as an open cable routing groove with intersecting teeth to avoid the cables being exposed on the side of the cabinet, causing cable damage and affecting the safe operation of the equipment.

[0025] Specifically, a number of reinforcing ribs 12 are provided at the inner corner of the bend between the first plate 7 and the second plate 8. The reinforcing ribs 12 are used to strengthen and fix the bend position between the first plate 7 and the second plate 8, increase the support strength of the bracket, and prevent the bracket from deforming or being damaged.

[0026] Specifically, the second plate 8 is provided with self-locking hooks 9, which have the same structure as the self-locking hooks 9 on the first plate 7. Specifically, four self-locking hooks 9, a third locking plate 13, and a fourth locking plate 14 are also provided, located at the corresponding positions of the irregularly shaped locking slots 18 when the second plate 8 is hung on the frame. The second plate 8 is provided with locking plates, which are located at the corresponding positions of the locking plate slots when the second plate 8 is hung on the frame. The locking plate slots provide upper and lower limits for the locking plates of the second plate 8. Figure 12As shown, the width from the edge of the first plate 7 away from the connection point with the second plate 8 is less than the width from the edge of the second plate 8 away from the connection point. When the first plate 7 is hung on the frame, the distance between the second plates 8 of a pair of brackets 6 at the same height on the frame is less than the width of the equipment to be supported. When the second plate 8 is hung on the frame, the distance between the first plates 7 of a pair of brackets 6 at the same height on the frame is greater than the width of the equipment to be supported. The purpose of setting the self-locking hook 9 and the locking plate on the second plate 8 at the same position as the first plate 7 is to allow the second plate 8 to be used to conduct an experiment on adjusting the position of the bracket 6. During adjustment, the second plate 8 is hung on the frame, and the distance between the pair of first plates 7 at the same height on the frame is greater than the distance of the equipment. In this way, the equipment can move up and down, and the bracket 6 will no longer obstruct the up and down movement of the equipment. This avoids the trouble of installing and removing fasteners every time the position of the traditional bracket is adjusted. After the position of the bracket 6 to be fixed is determined by the second plate 8, the bracket 6 is flipped over, and finally the first plate 7 is used to hang it on the frame to support the equipment.

[0027] Specifically, the second plate 8 is provided with an anti-slip groove 16 at the equipment support position, and an anti-slip pad is provided in the anti-slip groove 16. The anti-slip pad can be rubber, silicone or plastic parts with anti-slip protrusions, as long as it can play an anti-slip role.

[0028] Specifically, the self-locking hook 9, the card plate, the cable fixing groove 15, the reinforcing rib 12, and the anti-slip groove 16 are formed by stamping the first plate 7 and the second plate 8 into one piece, which saves costs and improves the production efficiency of the bracket 6 and the frame.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any modifications, alterations, substitutions, and variations made by those skilled in the art to the above embodiments are within the scope of the present invention.
