For example, patent application number: CN202110083687.X provides an embedded network intelligent information processing server, including a cabinet, a storage bin is provided on the cabinet, and a server is slidably connected in the storage bin, a conveying module is provided on one side of the storage bin, and a conveying frame is slidably connected to the conveying module, and a pushing limit frame is provided on the conveying frame, and a pushing limit frame is provided on the pushing limit frame. A pushing rod is provided, and one end of the pushing rod is fixedly connected to a clamping device, and a reciprocating screw rod is rotatably connected to the lower end surface of the conveying frame, and the reciprocating screw rod is connected to a power source. The device has automatic guiding, realizes automatic installation of servers, and automatically cleans all servers through a cleaning bin. Although this solution can realize automatic cleaning of servers, this solution can only complete simple cleaning work, and manual operation of staff is still required when the server needs to be debugged and repaired. Summary of the invention

[0005] The object of the present invention is to provide a computer network server cabinet to solve the problem that it is difficult for staff to repair the server due to height problems and the server being placed deep in the cabinet.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] Preferably, a computer network server cabinet comprises a cabinet body and a tray, wherein the trays are multiple and are arranged vertically inside the cabinet body, a rectangular frame is further provided inside the cabinet body, sliding rods are fixedly installed on the four corners of the rectangular frame, four guide rails are further provided on the inner wall of the cabinet body, four sliding rods are respectively slidably connected to the four guide rails, a control component with a telescopic rod is provided on the rectangular frame, one end of the telescopic rod is fixedly installed on the rectangular frame, a locking component with a clamp is provided on the telescopic rod, the clamps are multiple and are fixedly installed on the telescopic rod, and the clamps are respectively in contact with the tray, the locking component is used to lock the tray with the clamp, and the control component controls the clamp to move back and forth in the vertical direction by controlling the telescopic rod to extend and retract.

[0008] It is easy to understand that the design is provided with a locking assembly of the gripper inside the cabinet, and the gripper can be fixed to the tray by the locking assembly. After the gripper and the tray are fixed, they can be moved together to the outside of the cabinet through the rectangular frame, and a control assembly with a telescopic rod is also provided inside the cabinet. The control assembly can control the gripper and the tray to move up and down in the vertical direction by controlling the telescopic rod. The design solves the problem that the server is located deep in the cabinet and is inconvenient to repair through the rectangular frame and the locking assembly, and further solves the problem that the server is located high in the cabinet and is inconvenient to repair through the control assembly. Therefore, the design facilitates the staff to repair the server inside the cabinet, and the staff can lock multiple trays located high in the cabinet and move them together through the control assembly. The design improves the work efficiency of the staff.

[0009] Preferably, the control component includes a pull rod, a guide rail 2 is opened inside the rectangular frame, the pull rod is slidably connected to the guide rail 2, a connecting rod is fixedly connected to the pull rod, the connecting rod is fixedly connected to the top of the telescopic rod, and the pull rod is also connected to a handle, the handle is located on the outside of the guide rail 2, when the pull rod moves in the vertical direction, the telescopic rod follows the pull rod to move in the vertical direction.

[0010] It is easy to understand that when the rectangular frame brings the gripper and the tray out of the cabinet, the staff pulls the handle on the rectangular frame, and the handle drives the pull rod to move downward along the guide rail 2. The connecting rod moves together with the pull rod and drives the telescopic rod to move. At this time, the gripper on the telescopic rod will move downward with the telescopic rod. This design allows the staff to move the tray to the designated position in only two steps: pulling out the rectangular frame and pulling the handle downward. Therefore, the structure is simple, which saves the staff the difficulty of operation and improves the staff's work efficiency.

[0011] Preferably, the locking assembly includes a locking rod, the clamping hand is provided with a clamping groove, the clamping groove has two sides contacting the tray, the clamping hand and the tray are both provided with locking holes, the locking hole on the clamping hand is aligned with the locking hole on the tray, the bottom of the clamping hand is also fixedly connected with an arc sleeve, the axis of the arc sleeve is aligned with the axis of the locking hole, the locking rod is slidably connected to the inside of the arc sleeve, a reset groove is provided inside the locking rod, a gasket is fixedly installed inside the arc sleeve, the gasket is located inside the reset groove, and a spring 1 is provided between the gasket and the inner wall of the reset groove, a sliding groove is also provided inside the clamping hand, and a locking block is slidably connected to the sliding groove, one end of the locking block is chamfered and extends to the inside of the locking hole, a rectangular hole is provided on the locking rod, and a contact rod 1 is also fixedly connected to the locking block, a spring 2 is provided between the locking block and the inner wall of the sliding groove, and a contact rod 2 is fixedly installed on the inner wall of the cabinet.

[0012] It is easy to understand that when the staff presses the locking rod on the clamp hand, the locking rod squeezes the spring inside the arc sleeve and moves upward, and the rectangular hole on the locking rod cooperates with the locking block to lock the clamp hand and the tray together. When the staff completes the maintenance of the server on the tray and pushes the rectangular frame back into the cabinet, the contact rod 2 on the inner wall of the cabinet will squeeze the contact rod 1 on the locking block, and the locking block squeezes spring 2 and completely moves away from the rectangular hole. At this time, the clamp hand and the tray are unlocked. Therefore, this design only requires the staff to press the locking rod on the clamp hand to complete the locking of the tray, and when the staff resets the tray after completing the maintenance, the tray is automatically unlocked. The design has a simple structure and is easy to operate, which improves the work efficiency of the staff. The staff can lock any number of trays through the locking component, and these trays can be moved to the specified position together with the control component. Therefore, this design allows the staff to move multiple servers that need to be repaired at the same time, further improving the work efficiency of the staff.

[0013] Preferably, a ratchet is fixedly connected to the guide rail two, the handle is rotatably connected to the pull rod, a torsion spring is arranged between the handle and the pull rod, a gear is also rotatably connected to the inner wall of the pull rod, the gear is fixedly connected to the handle, a rack is also slidably connected inside the pull rod, the rack is meshed with the gear, a pawl is slidably connected to one end of the rack, a spring three is arranged between the pawl and the rack, the pawl is in contact with the ratchet, and when the handle is rotated in the clockwise direction, the pawl moves away from the ratchet.

[0014] It is easy to understand that when the staff pulls the handle, the handle will rotate around the pull rod, and the rotation of the handle will drive the gear to rotate. The rack meshing with the gear will move with the rotation of the gear, and the pawl at one end of the rack will move away from the ratchet on the guide rail 2. Only then can the staff pull the handle and the pull rod downward. When the tray moves to the appropriate position, the staff releases the handle. At this time, the handle is reset by the action of the torsion spring, and the gear also rotates and resets with the handle, and the pawl on the rack contacts the ratchet on the guide rail 2 again. At this time, the pull rod cannot move and the tray is fixed in the specified position. This design arranges a pawl on the pull rod and a ratchet on the guide rail 2 that cooperates with the pawl, so that the pull rod cannot move when no one pulls the handle, thereby avoiding the rectangular frame being damaged due to the sudden fall of the pull rod when the rectangular frame is pulled out. This design improves the reliability of the computer network server cabinet, and through the cooperation of the pawl and the ratchet, the staff can also stop the tray at any height according to actual conditions, further facilitating the maintenance of the staff and improving work efficiency.

[0015] Preferably, limit blocks are provided on both upper and lower sides of the tray, both upper and lower sides of the tray are in contact with the limit blocks, the limit blocks are fixedly connected to the inner wall of the cabinet, and the front end of the limit blocks is rounded.

[0016] It is easy to understand that this design sets limit blocks on the upper and lower sides of the pallet to provide support for the pallet and ensure the stability of the pallet in the cabinet. The front end of the limit block is also rounded, which allows the pallet to be better aligned with the limit block during the process of moving back to the cabinet. Therefore, this design improves the reliability of the computer network server cabinet.

[0017] Preferably, a plurality of the trays are provided with U-shaped grooves, and the U-shaped grooves on each of the trays are staggered.

[0018] It is easy to understand that the server is installed on the pallet, and the wires connected to the server can be placed in the middle of the U-shaped groove, and the U-shaped grooves on multiple pallets inside the cabinet are staggered. This allows the wires on the pulled-out pallet to not affect the wires on other pallets when the pallet is pulled out following the gripper. Similarly, the wires on other pallets will not affect the pulling out of the pallet. Therefore, this design ensures that the pallet will not be affected by the clutter of wires during mobile work, thereby improving the fluency of the control components and improving work efficiency.

[0019] Preferably, blocks are hinged on both sides of the tray, and torsion springs are provided at the hinges between the blocks and the tray. A slot is also provided inside the cabinet, and the blocks are slidably connected inside the slots. The maximum rotation angle of the blocks in the counterclockwise direction is 90°. A chamfer is provided at the inflection point of the slot, and the chamfer radius gradually decreases from top to bottom. The longest block length of the block on the topmost tray gradually decreases from top to bottom.

[0020] It is easy to understand that after the pallet is pulled out with the gripper, the limit block loses its function, causing the pallet to be stressed only on the side where the gripper is located. This causes the pallet to easily tilt during movement and maintenance by the staff, which in turn causes the pallet to bend or even be damaged. The design is hinged with blocks on both sides of the pallet. When the pallet moves, the blocks follow the pallet to move in the slot. When the pallet completes the translation and starts to move downward, the blocks pass through the inflection point in the slot, and the blocks are squeezed by the chamfers to rotate 90° counterclockwise and continue to move downward along the slot. When the pallet completes the movement, since the maximum rotation angle of the blocks is 90°, when the pallet tilts, the blocks will squeeze the inner wall of the slot to prevent the pallet from tilting. Therefore, this design avoids the problem of bending or even damage to the pallet caused by uneven force on the pallet. The problem is solved, and the service life of the pallet is improved. The design also gradually reduces the chamfer radius from top to bottom, and the length of the card block from top to bottom. This makes it impossible for the longer card block located at a higher place to rotate to the smaller inflection point during the pallet maintenance and lifting process. Therefore, when the pallet is lowered, the card block on the upper pallet will not rotate to the lower inflection point. When the pallet moves to the original position during the lifting process, the card block on the pallet will rotate to the matching inflection point to lock the pallet. Therefore, this design makes it possible for the card block to not affect the movement of the pallet during the descent of the pallet, and after the pallet is raised to the original position, the card block will lock the pallet so that the pallet cannot continue to rise, so that the pallet can be reset more accurately. Therefore, this design improves the reliability of the computer network server cabinet.

[0021] Preferably, the tray length is A, the maximum distance that the rectangular frame moves along the guide rail is B, and BA ≥ 10 cm.

[0022] It is easy to understand that when the pallet is locked by the clamp lock, the rectangular frame is pulled, and the distance the rectangular frame moves is equal to the distance the pallet moves. This design allows a gap of more than 10 cm to exist between the locked pallet and the pallet that has not been pulled out. The existence of the gap allows the pallet to be pulled out and away from the wires in the pallet that has not been pulled out. This ensures that the pallet will not be affected by the wires when it moves downward following the extension and retraction, eliminating the need for staff to sort out the wires and improving work efficiency.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The design is provided with a locking assembly of a gripper inside the cabinet. The gripper can be fixed to the tray through the locking assembly. After the gripper and the tray are fixed, they can be moved together to the outside of the cabinet through a rectangular frame. A control assembly with a telescopic rod is also provided inside the cabinet. The control assembly can control the gripper and the tray to move up and down in the vertical direction by controlling the telescopic rod. The design solves the problem that the server is located deep in the cabinet and is inconvenient to repair through the rectangular frame and the locking assembly. At the same time, the control assembly further solves the problem that the server is located high in the cabinet and is inconvenient to repair. The design facilitates the staff to repair the server inside the cabinet and improves the staff's work efficiency.

[0025] 2. The design is provided with a control component on the rectangular frame. When the rectangular frame brings the gripper and the tray out of the cabinet, the staff pulls the handle on the rectangular frame. At this time, the handle drives the pull rod to move downward along the guide rail 2. The connecting rod moves together with the pull rod and drives the telescopic rod to move. At this time, the gripper on the telescopic rod will move downward with the telescopic rod. This design enables the staff to move the tray to the designated position in only two steps: pulling out the rectangular frame and pulling the handle downward. Therefore, the structure is simple, which saves the staff the difficulty of operation and improves the staff's work efficiency.

[0026] 3. The design is provided with a locking assembly on the telescopic rod. When the staff presses the locking rod on the clamp, the rectangular hole on the locking rod cooperates with the locking block to lock the clamp and the pallet. When the staff completes the maintenance of the server on the pallet and pushes the rectangular frame back into the cabinet, the second contact rod on the inner wall of the cabinet will squeeze the first contact rod on the locking block. The locking block squeezes the second spring and completely moves away from the rectangular hole, and the clamp and the pallet are unlocked. This design improves work efficiency, and the staff can lock any number of designated pallets through the locking assembly. These pallets can be moved to the designated position together with the control assembly. Therefore, this design allows the staff to move multiple servers that need to be repaired at the same time, further improving the work efficiency of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
