[0020] Compared with the prior art, the present invention provides a network cabinet with a pallet that can be quickly disassembled, and has the following beneficial effects:

[0021] 1. This network cabinet with a quickly removable pallet uses positioning components instead of screws to fix the pallet in the cabinet, which can achieve quick removal and installation of the pallet in the cabinet, simplifying the disassembly and assembly of the pallet and abandoning the traditional screw fixing method. It not only improves the assembly efficiency of the cabinet, but also reduces the assembly difficulty of the cabinet, and is suitable for application scenarios that require frequent disassembly and installation.

[0022] 2. The network cabinet with a quickly removable pallet is equipped with an auxiliary support component to provide auxiliary support for the end of the pallet that is moved out of the cabinet when the pallet is moved out of the cabinet, so as to prevent the pallet from sagging under the action of gravity due to lack of support at the bottom. The sagging will generate additional torque, which may cause the slide rail to deform or even tear the cabinet connection point in the long term, making it impossible to return to the inside of the cabinet normally, thereby destroying the overall structural stability and increasing the difficulty of disassembly, thereby effectively improving the service life of the cabinet and reducing the difficulty of disassembly and assembly.

[0023] 3. The network cabinet with quickly removable pallets uses the second positioning rod to position the pallet and the slide rail through the positioning assembly, and then limits the connection between the pallet and the cabinet side panel. When all the pallets in the cabinet are moved out, the side panels are no longer restricted and can rotate relative to the main shell, thereby opening the interior of the cabinet, making it easier for staff to inspect the interior of the cabinet and avoiding the difficulty of inspection caused by the small space inside the cabinet.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements; for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] As Figures 1 to 3As shown, this embodiment proposes a network cabinet with a quickly removable pallet, comprising a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1, and also comprising: a pallet body 3, a slide rail 4 and an auxiliary support assembly, wherein the pallet body 3 is provided with multiple pieces and is distributed in sequence from top to bottom along the cabinet body 1, for supporting and placing electronic devices in the cabinet body 1; the slide rail 4 is fixed to the inner wall of the cabinet body 1, and the pallet body 3 is slidably connected to the slide rail 4, and the pallet body 3 can be moved outward and disassembled along the slide rail 4 to the outside of the cabinet body 1; the auxiliary support assembly is provided in the cabinet body 1, for auxiliary support of the pallet body 3 moved out of the cabinet body 1, to prevent the pallet body 3 from sagging under the action of gravity due to lack of support at the bottom, which will generate additional torque, and long-term action may cause the slide rail 4 to deform or even tear the connection point of the cabinet body 1, making it impossible to return to the cabinet body 1 normally Internally, it destroys the stability of the overall structure and increases the difficulty of disassembly, thereby effectively improving the service life of the cabinet and reducing the difficulty of disassembly and assembly; wherein, a positioning component that cooperates with the cabinet body 1 is provided on the pallet body 3, which effectively prevents the pallet body 3 from moving freely in the cabinet body 1, and the positioning component is only operated when the pallet body 3 is moved out or disassembled; the positioning component is connected to the auxiliary support component, and the auxiliary support component automatically moves when the positioning component works; the present application uses the positioning component to replace the screws to fix the pallet body 3 in the cabinet body 1, which can realize the rapid disassembly and installation of the pallet in the cabinet body 1, simplify the disassembly and assembly of the pallet, and abandon the traditional screw fixing method, which not only improves the assembly efficiency of the cabinet, but also reduces the assembly difficulty of the cabinet, and is suitable for application scenarios that require frequent disassembly and installation.

[0038] like Figure 3 、 Figure 4 、 Figure 6 and Figure 8As shown, as a preferred embodiment, on the basis of the above-mentioned method, the auxiliary support assembly further includes a rotating shaft 5 rotatably connected to the cabinet body 1 and a telescopic plate 501 arranged on the rotating shaft 5, and the telescopic plate 501 is connected to the positioning assembly at one end away from the rotating shaft 5, and a ratchet part 502 is fixed on the rotating shaft 5, and a pawl part 503 is provided on the inner wall of the cabinet body 1 that is movably opposed to the ratchet part 502; after the restriction of the positioning assembly on the support plate body 3 and the cabinet body 1 is released, the support plate body 3 is pulled outward, and the telescopic plate 501 is stretched when the support plate body 3 moves. During this period, the telescopic plate 501 drives the ratchet part 502 through the rotating shaft 5 The wheel portion 502 rotates, and the pawl portion 503 limits the rotation direction of the ratchet portion 502 to prevent the telescopic plate 501 from shrinking at will, affecting the support of the telescopic plate 501 on the end of the support plate body 3. The ratchet and pawl are existing technologies and will not be described in detail here. By supporting one end of the support plate body 3, the support plate body 3 is prevented from sagging under the action of gravity due to lack of support at the bottom. The sagging will generate additional torque, and long-term action may cause the slide rail 4 to deform or even tear the connection point of the cabinet 1, making it impossible to return to the inside of the cabinet 1 normally, destroying the overall structural stability and increasing the difficulty of disassembly, thereby effectively improving the service life of the cabinet and reducing the difficulty of disassembly and assembly.

[0039] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the positioning assembly includes an ear plate 6 fixedly mounted on the lower side of the support plate body 3, a first positioning rod 601 slidably connected to the ear plate 6, an end plate 602 arranged at the end of the first positioning rod 601, a first elastic element 603 sleeved on the first positioning rod 601 and connected to the end plate 602 and the ear plate 6 at both ends, a pull rope 604 fixedly connected to the end plate 602 and a toggle plate 605 slidably connected to the lower side of the support plate body 3, and the inner wall of the cabinet 1 and the telescopic plate 501 are all on the inner wall of the cabinet 1 and the telescopic plate 501. A first socket 7 is provided which cooperates with the first positioning rod 601; when it is necessary to release the positioning component from limiting the pallet body 3 and the cabinet body 1, by pulling the toggle plate 605, the toggle plate 605 applies tension to the end plate 602 through the pull rope 604, so that the end plate 602 drives the first positioning rod 601 to move out of the first socket 7 of the cabinet body 1, so that the pallet body 3 can slide outward in the slide rail 4. It should be noted that at this time the first positioning rod 601 has not yet moved out of the first socket 7 of the telescopic plate 501, so that it can drive the telescopic plate 501 to move when the pallet moves.

[0040] like Figure 5 and Figure 6As shown, as a preferred embodiment, on the basis of the above method, further, a guide rod 8 is fixed on the lower side of the support plate body 3, and the pull rope 604 is slidably connected to the guide rod 8; the guide rod 8 can guide the moving direction of the pull rope 604, so that the movement of the toggle plate 605 can drive the first positioning rod 601 to move horizontally.

[0041] like Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, a slider 6051 is fixed on the toggle plate 605, and a movable groove 13 for sliding the slider 6051 is opened at the bottom of the support plate body 3, and a third elastic element 131 is provided between the inner wall of the movable groove 13 and the slider 6051; when the toggle plate 605 moves, it slides in the movable groove 13 through the slider 6051, thereby improving the smoothness of the movement of the toggle plate 605, and when the slider 6051 moves, the third elastic element 131 is stretched so that the toggle plate 605 can move back under the elastic force of the third elastic element 131 when it is not under force. The third elastic element 131 can be a spring or other device that can drive the slider 6051 to reset.

[0042] like Figure 4 、 Figure 6 and Figure 7 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the positioning assembly further includes a second positioning rod 9 slidably connected to the slide rail 4, an annular plate 901 is fixed on the second positioning rod 9, a slide groove 902 for sliding the annular plate 901 is opened in the slide rail 4, a second elastic element 903 is provided between the inner wall of the slide groove 902 and the annular plate 901, and a second socket 10 cooperating with the second positioning rod 9 is opened on the slide rail 4 and the support plate body 3;

[0043] Furthermore, the second positioning rod 9 is an elastically retractable positioning rod, and the top of the second positioning rod 9 is provided with a first inclined surface that is movably abutted against the support plate body 3, and the bottom of the second positioning rod 9 is fixed with a force block 904, and the bottom of the force block 904 is provided with a second inclined surface that cooperates with the first positioning rod 601, and the bottom of the force block 904 is connected to the pawl part 503 through a connecting rod.

[0044] Specifically, the positioning assembly further includes a second positioning rod 9 for positioning the slide rail 4 and the pallet body 3, so as to position the cabinet 1 and the pallet body 3. The pallet body 3 is fixed in the cabinet 1 longitudinally and transversely by the first positioning rod 601 and the second positioning rod 9 respectively. When the cabinet is subjected to external impact, such as transportation collision or earthquake, the two-way fixation can provide multi-directional constraints, reduce the risk of the pallet dislocation, and avoid relying solely on the positioning rods in the transverse or longitudinal direction for positioning, so that stress is concentrated at the plug-in point, which easily leads to deformation of the side wall structure. After the multi-directional positioning rod is set, the load is transmitted to the cabinet and the pallet body 3 through the two-way node, which conforms to the mechanical principle of "triangle stability".

[0045] It should be noted that, when the first positioning rod 601 moves out of the first socket 7 of the cabinet 1 and has not moved out of the first socket 7 of the telescopic plate 501, the end of the first positioning rod 601 no longer applies a thrust to the second inclined surface of the force-bearing block 904, and the stretched second elastic element 903 drives the second positioning rod 9 to move downward, so that the second positioning rod 9 moves out of the second socket 10 of the support plate body 3, thereby releasing the positioning restriction on the support plate body 3, so that the support plate body 3 can slide smoothly to the outside of the cabinet 1; when the force-bearing block 904 moves downward, the pawl part 503 is driven by the connecting rod to abut against the ratchet part 502, ensuring that the subsequent telescopic plate 501 can effectively support the support plate body 3 moved out of the cabinet 1; when the support plate body 3 is subsequently reset and moved back, the first positioning rod 601 is driven to abut against the ratchet part 502, ensuring that the subsequent telescopic plate 501 can effectively support the support plate body 3 moved out of the cabinet 1 The end 601 applies force to the second inclined surface, and a ball bearing can be set at the end of the first positioning rod 601 to reduce sliding wear. The force block 904 drives the first positioning rod 601 to move upward, so that the force block 904 synchronously drives the pawl part 503 to move upward, and releases the restriction of the pawl part 503 on the ratchet part 502, so that the telescopic plate 501 can drive the rotating shaft 5 to reset and rotate when the support plate body 3 moves back. When the support plate body 3 moves back, it presses the first inclined surface on one side of the end of the second positioning rod 9, and the second positioning rod 9 elastically contracts. When the second positioning rod 9 moves to the second socket 10 that is initially matched, the second positioning rod 9 elastically recovers and is inserted into the second socket 10, which restricts the support plate body 3 vertically and restricts the support plate body 3 from moving toward the outside of the cabinet 1.

[0046] like Figure 4 and Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, a plurality of elastic metal baffles 11 are evenly arranged on the circumference of the first positioning rod 601, and the elastic metal baffles 11 are movably opposed to the telescopic plate 501; when it is necessary to release the positioning component from limiting the support plate body 3 and the cabinet body 1, by pulling the toggle plate 605, the toggle plate 605 applies a pulling force to the end plate 602 through the pull rope 604, so that the end plate 602 drives the first positioning rod 601 to move out of the first insertion hole 7 of the cabinet body 1, so that the support plate body 3 can slide outward in the slide rail 4. Due to the design of the elastic metal baffles 11 The arrangement allows the operator to clearly know that the first positioning rod 601 has moved to the telescopic plate 501 when resistance is felt when pulling the first positioning rod 601. The operator can decide to apply a greater force to the toggle plate 605 as needed to cause the elastic metal baffle 11 to retract toward the central axis of the first positioning rod 601, and the first positioning rod 601 to move out of the first insertion hole 7 of the telescopic plate 501, thereby causing the entire tray to slide out of the slide rail 4 and disassemble the tray; or the operator does not move the first positioning rod 601 out of the insertion hole of the telescopic plate 501, but only moves the tray out of the cabinet 1 and performs maintenance on the electronic components on the tray.

[0047] like Figure 1 、 Figure 2 、 Figure 3 and Figure 9 As shown in Figure 9 , as a preferred embodiment, on the basis of the above method, further, the cabinet body 1 includes a main housing 101 and side plates 102 rotatably connected to both sides of the main housing 101 through pin shafts. The cabinet door 2 is connected to the side plates 102 through hinges. The slide rail 4, the first jack 7 and the rotating shaft 5 are all arranged on the side plates 102. By using the second positioning rod 9 of the positioning component to position the tray and the slide rail 4, and then connecting and limiting the tray and the side plate 102 of the cabinet body 1. When all the trays in the cabinet body 1 are removed, the side plate 102 is no longer restricted, and the side plate 102 can rotate relative to the main housing 101, so that the interior of the cabinet body 1 is opened, which is convenient for the staff to repair the interior of the cabinet body 1 and avoids the difficulty of repair caused by the narrow interior space of the cabinet body 1.

[0048] [[ID=⑥]]As[[ID=⑦]] Figure 9 [[ID=⑧]]shown, as a preferred embodiment, on the basis of the above method, further, a U-shaped frame 12 is further arranged on the inner wall of the main housing 101, and a sealing pad 121 which is movably abutted against the side plate 102 is fixedly arranged on the outer side wall of the U-shaped frame 12. When the side plate 102 rotates and approaches the main housing 101, the inner wall of the side plate 102 abuts against the sealing pad 121, ensuring the sealing performance of the connection between the side plate 102 and the main housing 101 and reducing the probability of dust and water vapor entering. [[ID=⑨]] [[ID=⑩]]

[0049] [[ID=⑪]]The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes an equivalent replacement or change, and should be covered within the protection scope of the present invention.
