[0017] This invention provides a computer network room cabling device. It has the following advantages:
[0018] 1. This computer network room cabling equipment protects the cable connections by incorporating a cable management and pressing mechanism. Because the cables in the computer room are often long and prone to tangling, and their varying lengths make maintenance difficult, the cable management and pressing mechanism solve this problem by securing the cables inside the winding machine and mounting bracket, allowing for a pre-existing length for maintenance, and then winding up any remaining cable within the machine.
[0019] 2. This computer network room cabling equipment utilizes a storage mechanism for placing and transporting cables. The mounting frame is divided into two chambers, each containing an arc-shaped groove for cable placement. During cable movement, the cables rest within the smooth arc-shaped grooves, reducing wear caused by contact with rough surfaces. Furthermore, by controlling the position of the pressure plate and connectors, the cables can be moved from one end of the mounting frame to the other, facilitating the user's feeding of one end of the cable into the winding machine.
[0020] 3. This computer network room cabling equipment protects the wire connection ends by incorporating protective components. The wire connection ends are fixed in a trapezoidal plate, and a first rubber rod is installed at the bottom of the trapezoidal plate to press and protect the wire connection ends, thus fixing their position and facilitating maintenance by workers.
[0021] 4. This computer network room cabling equipment features a pressing mechanism for limiting and moving the wires. When the wire is stationary, the pressing mechanism's locking plate protects the wire and absorbs moisture from the space around it. The moisture-absorbing material can be replaced in real time by rotating the moisture-absorbing component. When the wire needs to be removed for maintenance, the wire can be moved by controlling the position of the locking plate. Attached Figure Description

The pressure plate 605 is slidably connected to the outside of the connector 606.
[0036] The pressing mechanism 7 is used to absorb moisture and protect the wire. The pressing mechanism 7 is set inside the fixed frame 5. The pressing mechanism 7 includes a third telescopic rod 701. A disc 702 is fixedly connected to the outside of the third telescopic rod 701. A moisture-absorbing component 703 is fixedly connected to the outside of the disc 702. There are two moisture-absorbing components 703, which are arranged symmetrically.
[0037] Before using the equipment, adjust the storage mechanism 6. Manually place the power supply end of the power cord into the storage mechanism 6, which will then guide it to the other end of the mounting bracket 5. Allow for a maintenance length, and adjust the storage mechanism 6 and pressing mechanism 7 to secure the connection between the power cord and the appliance, and then secure the power cord within the mounting bracket 5. Manually feed the power supply end of the power cord into the winding machine, ensuring it protrudes through the top of the winding machine and connects to the power source. When maintenance is required on the connection between the power cord and the appliance, adjust the storage mechanism 6 and pressing mechanism 7 to control the position of the power cord.
[0038] The storage mechanism 6 also includes a shelf 607, which is fixedly connected to the outside of the fixed frame 5. A motor is installed inside the shelf 607, and the third telescopic rod 701 is fixedly connected to the output end of the motor.
[0039] When it is necessary to adjust the direction of the pressing mechanism 7, the motor is turned on. The motor drives the third telescopic rod 701 to rotate, which in turn drives the pressing mechanism 7 to rotate, thereby adjusting the direction of the pressing mechanism 7.
[0040] The storage mechanism 6 also includes a connecting rod 610 and a fixing cylinder 608. The connecting rod 610 is fixedly connected to the top of the shelf plate 607, and a mounting base is fixedly connected to the bottom of the connecting rod 610.

[0041] The protective component 609 includes a second telescopic rod 6091, a connecting rod 6092 fixedly connected to the bottom of the second telescopic rod 6091, a blocking plate 6093 fixedly connected to the outside of the connecting rod 6092, the second telescopic rod 6091 passing through the interior of the fixed cylinder 608, and the second telescopic rod 6091 fixedly connected to the bottom of the frame plate 607.
[0042] A first adjusting rod 6094 is fixedly connected to the bottom of the connecting rod 6092. A trapezoidal plate 6095 is fixedly connected to the bottom of the first adjusting rod 6094. A first rubber rod is installed at the bottom of the trapezoidal plate 6095. Multiple first rubber rods are provided.
[0043] Before using the equipment, the second telescopic rod 6091 is in its initial state, at which time the connecting rod 6092 is in a higher position in the fixed cylinder 608, and the opening of the fixed cylinder 608 is exposed. Open the first telescopic rod 603, which drives the connecting piece 606, the elastic rod 604, and the pressure plate 605 to move outwards until the elastic rod 604, the pressure plate 605, and the connecting piece 606 are in the fixed cylinder 608. Manually pull the pressure plate 605 to squeeze the elastic rod 604, and wrap one end of the power cord connected to the power source around the connecting piece 606. Release the elastic rod 604 and the pressure plate 605, and the pressure plate 605 will press the power cord onto the connecting piece 606, fixing the position of one end of the power cord. Adjust the first telescopic rod 603 to its initial state. The first telescopic rod 603 sends one end of the wire connected to the power source to the other end of the fixed frame 5. Then, open the second telescopic rod 6091. The second telescopic rod 6091 drives the connecting rod 6092, the blocking plate 6093, the first adjusting rod 6094, and the trapezoidal plate 6095 to move downward. The trapezoidal plate 6095 presses down on one end of the wire connected to the electrical appliance. The blocking plate 6093 does not close the opening of the fixed cylinder 608.
[0044] Manually remove the wire from the pressure plate 605, leaving a maintenance length at the end of the wire connected to the power source. Manually feed the end of the wire connected to the power source into the winding machine to wind up the remaining wire. The end of the wire connected to the power source will protrude through the top of the winding machine and be connected to the power source.
[0045] When electrical wiring needs to be inspected, adjust the second telescopic rod 6091 to its initial state and release the connection between the wire and the appliance.
[0046] A central shaft 704 is fixedly connected to the outside of the disc 702. A push rod 705 is also fixedly connected to the outside of the disc 702. A sliding ring 708 is slidably connected to the outside of the central shaft 704. The sliding ring 708 is fixedly connected to the push rod 705. Vertical rods 709 are fixedly connected to the top and bottom of the sliding ring 708. A fourth telescopic rod 706 is fixedly connected to the outside of the vertical rod 709. A buckle plate 707 is fixedly connected to the outside of the fourth telescopic rod 706. A second rubber rod is installed at the bottom of the buckle plate 707. There are two vertical rods 709, two fourth telescopic rods 706, and two buckle plates 707, and they are arranged symmetrically.
[0047] With the wire positioned in the arc-shaped groove 611, push rod 705 is activated. Push rod 705 drives sliding ring 708, vertical rod 709, fourth telescopic rod 706, and buckle plate 707 to move. Moisture-absorbing component 703 and fourth telescopic rod 706 near the wire are activated. Fourth telescopic rod 706 drives buckle plate 707 to move towards the wire. Buckle plate 707 gradually contacts the wire, and the second rubber rod at the bottom of buckle plate 707 fixes the position of the wire.
[0048] When it is necessary to perform maintenance work on the wires, gradually adjust the push rod 705 to the initial state. As the push rod 705 moves the buckle plate 707, the buckle plate 707 moves the second rubber rod and the wire, thereby moving the wire of the reserved length towards the connection end, which facilitates the maintenance work.
[0049] The moisture-absorbing assembly 703 includes a fifth telescopic rod 7031, a top plate 7032 fixedly connected to the top of the fifth telescopic rod 7031, a groove 7033 is provided inside the top plate 7032, moisture-absorbing material is placed in the groove 7033, a second adjusting rod 7034 is fixedly connected to the top of the top plate 7032, a cross plate 7035 is fixedly connected to the top of the second adjusting rod 7034, and a moisture-absorbing plate 7036 is fixedly connected to the bottom of the cross plate 7035.
[0050] With the wire in the arc groove 611, the fifth telescopic rod 7031 near the wire is activated. The fifth telescopic rod 7031 drives the top plate 7032 to move towards the wire. The cross plate 7035 does not contact the wire, and the moisture-absorbing material in the groove 7033 absorbs moisture from the space where the wire is located.
[0051] When it is necessary to replace the moisture-absorbing material, adjust the fifth telescopic rod 7031 and the fourth telescopic rod 706 to their initial state, turn on the motor, and the motor will drive the third telescopic rod 701 to rotate, which in turn drives the moisture-absorbing component 703 to rotate, thereby adjusting the orientation of the moisture-absorbing component 703.
[0052] Working principle: Before using the equipment, the second telescopic rod 6091 is in its initial state, at which time the connecting rod 6092 is in the higher position in the fixed cylinder 608, and the opening of the fixed cylinder 608 is exposed. Open the first telescopic rod 603, which drives the connecting piece 606, the elastic rod 604, and the pressure plate 605 to move outwards until the elastic rod 604, the pressure plate 605, and the connecting piece 606 are in the fixed cylinder 608. Manually pull the pressure plate 605 to squeeze the elastic rod 604, and wrap one end of the wire connected to the power supply around the connecting piece 606. Release the elastic rod 604 and the pressure plate 605, and the pressure plate 605 will press the wire onto the connecting piece 606, fixing the position of one end of the wire. Adjust the first telescopic rod 603 to its initial state. The first telescopic rod 603 sends one end of the wire connected to the power source to the other end of the fixed frame 5. Then, open the second telescopic rod 6091. The second telescopic rod 6091 drives the connecting rod 6092, the blocking plate 6093, the first adjusting rod 6094, and the trapezoidal plate 6095 to move downward. The trapezoidal plate 6095 presses down on one end of the wire connected to the electrical appliance. The blocking plate 6093 does not close the opening of the fixed cylinder 608.
[0053] Manually remove the wire from the pressure plate 605, leaving a maintenance length at the end of the wire connected to the power source. Manually feed the end of the wire connected to the power source into the winding machine to wind up the remaining wire. The end of the wire connected to the power source will protrude through the top of the winding machine and be connected to the power source.
[0054] With the wire positioned in the arc-shaped groove 611, push rod 705 is activated. Push rod 705 drives sliding ring 708, vertical rod 709, fourth telescopic rod 706, and buckle plate 707 to move. Moisture-absorbing component 703 and fourth telescopic rod 706 near the wire are activated. Fourth telescopic rod 706 drives buckle plate 707 to move towards the wire. Buckle plate 707 gradually contacts the wire, and the second rubber rod at the bottom of buckle plate 707 fixes the position of the wire.
[0055] The fifth telescopic rod 7031, which is close to the power line, is activated. The fifth telescopic rod 7031 moves the top plate 7032 toward the power line. The cross plate 7035 does not contact the power line. The moisture-absorbing material in the groove 7033 absorbs moisture from the space where the power line is located.
[0056] When it is necessary to perform maintenance work on the wires, adjust the second telescopic rod 6091 to the initial state, release the connection end between the wire and the appliance, and gradually adjust the push rod 705 to the initial state. As the push rod 705 moves the buckle plate 707, the buckle plate 707 moves the second rubber rod and the wire, thereby moving the wire of the reserved length towards the connection end, which facilitates the maintenance work.
[0057] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
