Description

Technical Field

[0001] The invention belongs to the technical field of display cabinets, and in particular relates to a display cabinet that is easy to move slightly. Background Art

[0002] The header cabinet is generally located at the end of a row of cabinets. The header cabinet is a device that provides network wiring transmission services or power distribution management for cabinets arranged in rows or divided by functional areas. It contains many electrical components such as circuit breakers.

[0003] The header cabinet is generally not easily moved after installation, but it may be moved slightly under special circumstances, such as maintenance. The movement of the header cabinet is more difficult because the number and types of connections between the header cabinet and other cabinets are large and complicated. Since the lengths of various connections are not uniform, moving the header cabinet is likely to cause some shorter connections to be straightened and tightened first, which on the one hand restricts the movement of the header cabinet, and on the other hand, forcibly moving the header cabinet will cause the connections to break.

[0004] In addition, the internal installation layout of the cabinet includes two parts: the installation of electrical components and the connection of lines. The installation of electrical components is relatively easy and simple, while the connection of lines between the electrical components inside and between the electrical components inside and other cabinets needs to be completed by experienced professional operators. Patent application number 202022603749.9 discloses a cabinet that is easy to install and construct, in which multiple movable doors are designed on the four sides of the cabinet to facilitate the installation of electrical components into the cabinet and the maintenance of electrical components and lines. These ideas can be used as a reference and optimized and improved.

[0005] The present invention designs a terminal cabinet with three movable sides and convenient for small-range movement, which realizes the convenience of installation of the terminal cabinet and ensures that the output line of the terminal cabinet does not have a great influence on its small-range movement. Summary of the invention

[0006] Based on this, it is necessary to provide a slightly movable cabinet for the problems existing in the current cabinet. The present invention can facilitate the installation and connection of electrical components and circuits and the later maintenance of electrical components and circuits by rotating and swinging the three component box components arranged on the three sides of the cabinet assembly around the corresponding rotating pins. The installation of electrical components in the component box assembly and the connection of circuits can be completed without professional operators. When the present invention moves slightly, the trigger component arranged at the bottom of the cabinet triggers the transmission of the loosening component arranged in the middle of the cabinet assembly to moderately relax the connection between the first component in the component box assembly and other cabinets, ensuring that the present invention has appropriate moving space during the movement process and will not pull the circuit and cause the circuit to be broken. In the present invention, the wire feeding component located on the top plate can release the circuit loosened by the loosening component to the outside of the cabinet assembly during its movement, keeping the circuit in the cabinet assembly in a moderately straightened state during the movement process to prevent the loosened circuit from being disordered, and at the same time ensuring that the present invention will not break the circuit due to pulling due to the tension of the circuit length during the small movement process. The membrane sleeve in the wire loosening assembly of the second scheme of the present invention can assist in releasing all the wires crowded in the wire threading barrel and not loosened due to the movement of the wire threading barrel toward the first wire threading hole or the second wire threading hole relative to the wire threading barrel when the cabinet assembly moves slightly, thereby ensuring that the wires in the cabinet assembly always remain moderately taut and will not be disordered.

The wire feeding assembly 300 located on the top plate 107 of the present invention can release the wires relaxed by the wire loosening assembly 500 to the outside of the cabinet assembly 100 during its movement, so as to keep the wires in the cabinet assembly 100 in a properly straightened state during the movement and prevent the relaxed wires from becoming disordered, and at the same time ensure that the wires will not break due to pulling due to the tight wire length during the small movement of the present invention. The membrane sleeve 516 in the wire loosening assembly 500 of the second scheme of the present invention can make the wires crowded in the threading barrel 501 and not relaxed due to the movement of the threading barrel 501 all auxiliaryly released in the direction of the first threading hole 108 or the second threading hole 112 relative to the threading barrel 501 when the cabinet assembly 100 moves slightly, so as to ensure that the wires in the cabinet assembly 100 always remain properly tensioned and will not become disordered.

[0069] The operation process of the present invention is as follows:

[0070] In the initial state, the rod 701 of the locking assembly 700 on the door 411 of the component box assembly 400 is inserted into the second slot 403 at the bottom of the box body 401 and the first slot 104 on the bottom plate 101, so that the box body 401 of the component box assembly 400 is in a closed state to the corresponding side of the cabinet assembly 100, the door 411 is closed to the outer side of the corresponding box body 401, and the second spring 703 is in a compressed state. The ball wheel 202 in the trigger assembly 600 is located in the first guide sleeve 103 and maintains a certain distance from the ground, the first pull rope 509 is in a straightened state, the radial distance between the slide seat 310 in the wire feeding assembly 300 and the first ring 301 is the smallest, the rubber strip 504 on the threading barrel 501 in the loosening assembly 500 is closed to the corresponding whole line groove 502, and the membrane sleeve 516 is in a tight state under the action of the corresponding set of second pull ropes 514.

[0071] like Fig. 22 As shown, when installing the first component 408 and the second component 409 in the box body 401 of the component box assembly 400 and connecting the lines, the handle 705 on the box door 411 of the component box assembly 400 is pushed up, and the handle 705 drives the insertion rod 701 to disengage from the second slot 403 at the bottom of the box body 401 and the first slot 104 of the bottom plate 101 and further compress the corresponding second spring 703, and the box door 411 opens the box body 401 and the box body 401 opens the corresponding side of the cabinet assembly 100, and the first component 408 and the second component 409 are respectively inserted into the corresponding first clamping strip 406 on the back plate of the box body 401, and the output line of the first component 408 is passed from the corresponding third threading hole 405 through the corresponding side threading barrel 501 and the guide ring 113 to pass through the first threading hole 108 or the second threading hole 112 in sequence, and the line passing through the first threading hole 108 is led out from the first ring 301 and installed and fixed in the line card 312 at the corresponding position.

[0072] After the installation and line connection of the first component 408 and the second component 409 in the component box assembly 400 are completed, the rod 701 is pushed up by the handle 705 to close the box door 411 in the component box assembly 400 and the corresponding side of the box body 401 to the cabinet assembly 100. Then, the force on the corresponding rod 701 is removed, and the rod 701 is inserted into the second slot 403 at the bottom of the corresponding box body 401 and the first slot 104 on the bottom plate 101 under the action of the corresponding second spring 703, thereby completing the locking and closure of the component box assembly 400 on the corresponding side of the cabinet assembly 100 by the locking assembly 700.

[0073] When the present invention needs to be moved, the hand wheel 616 is manually rotated, and the hand wheel 616 drives the two sliders 607 to move downward synchronously through the fourth rotating shaft 615, the ninth gear 614, the eighth gear 613, the third rotating shaft 612, the seventh gear 611, the sixth gear 610 and the two screws 608. The two sliders 607 drive the second rotating seat 601 to move downward synchronously through the corresponding telescopic rods 603, and the second rotating seat 601 drives the ball wheel 202 to move downward. When the ball wheel 202 reaches the ground, as the ball wheel 202 and the ground are squeezed against each other, the two telescopic rods 603 are synchronously compressed, and the first spring 605 in the telescopic rod 603 is further compressed. The ball wheel 202 drives the first rack 506 connected thereto through the first pull rope 509 to move downward synchronously, and the first rack 506 connected to the first pull rope 509 is driven by the fourth gear 508. The first rack 506 and another first rack 506 drive the two threading tubes 501 to move toward the guide ring 113 on the corresponding side, so that the line between the first element 408 and the guide ring 113 is loosened. At the same time, the third gear 309 in the loosening assembly 500 rotates synchronously driven by the fourth gear 508. The third gear 309 drives the vortex bar 313 to rotate through the second gear 308, the first rotating shaft 307, the first gear 305, the gear ring 304 and the second ring 303. All the sliding sleeves 311 slide relative to the vortex bar 313. Under the action of the vortex bar 313, the sliding sleeve 311 drives the corresponding sliding seat 310 to move radially away from the first ring 301. The sliding sleeve 311 drives the line to be transmitted toward the adjacent cabinet through the line card 312, so that the present invention has a certain movement range to prevent the line from being tightened and broken during the movement of the present invention.

[0074] In order to prevent the line in the threading barrel 501 from being crowded and unable to be effectively relaxed while the threading barrel 501 moves, and to prevent the wire feeding assembly 300 from pulling the line in the threading barrel 501, a film sleeve 516 is provided in the threading barrel 501. When the fourth gear 508 rotates, it drives the two fifth gears 511 to rotate through the second rotating shaft 510. The two fifth gears 511 respectively drive the two fourth rings 513 to move through the corresponding two second racks 512. The fourth ring 513 pulls the film sleeve 516 to move relative to the threading barrel 501 through the second pull rope 514. The film sleeve 516 drives the line crowded in the threading barrel 501 to move toward the corresponding side guide ring 113, thereby ensuring that the line loosening assembly 500 does not form excessive pulling on the line between the guide ring 113 and the threading barrel 501, thereby avoiding the line from being broken.
