A network cabinet with an extended structure for computer system integration services

Abstract

This invention relates to the field of network cabinet technology and discloses a network cabinet for computer system integration services with an expandable structure. The cabinet includes an upper shell, a lower shell, a load-bearing component, and a lifting component. The lifting component includes a rack, gears, and a drive component. When the cabinet's installation capacity needs to be increased, the operator drives two gears to rotate synchronously via the drive component. The gears climb upwards along the racks fixed to both sides of the lower shell, causing the upper shell to move vertically upwards relative to the lower shell. During the upward movement, the overlap between the upper and lower shells gradually decreases, and the effective vertical communication area between the internal spaces of the upper and lower shells increases accordingly. When it needs to be restored to the standard height or used for transport, the drive component is rotated in the opposite direction until it returns to the lowest position. At this point, the overall height of the cabinet is reduced, facilitating handling and storage.

Description

Technical Field

[0001] This invention relates to the field of network cabinet technology, and in particular to a network cabinet for computer system integration services with an expandable structure. Background Technology

[0002] Network cabinets are infrastructure used in computer system integration services to centrally install network equipment such as servers, switches, and patch panels. During system expansion or equipment upgrades, the vertical installation capacity of the cabinet often needs to be dynamically adjusted; therefore, network cabinets with high scalability have become an important requirement in this field.

[0003] The prior art discloses a network cabinet with an expansion structure (such as CN215898235U), which sets a connecting block and a slider at the rear end of the cabinet shell so that the expansion shell can be manually pulled upward. Then, by tightening four limit bolts, the ends of the bolts abut against the outer surface of the cabinet shell, and the expansion shell is fixed at a certain height by friction.

[0004] However, the existing solutions mentioned above have obvious shortcomings in actual use: the expansion shell and the equipment installed inside it are quite heavy, and it is very difficult for operators to pull it up manually, and it is also difficult to accurately control the lifting height; in addition, the sliders on both sides are prone to asynchrony when pulled manually, which can cause the expansion shell to jam or tilt, affecting normal use. Summary of the Invention

[0005] The purpose of this invention is to provide a network cabinet for computer system integration services with an expandable structure, which solves the problems of laborious manual lifting and lowering operations and jamming caused by asynchronous operation on both sides in the prior art.

[0006] To achieve the above objectives, the present invention provides a network cabinet for computer system integration services with an expandable structure, comprising an upper shell, a lower shell, a load-bearing component, and a lifting component. The upper shell is slidably connected to the lower shell and is sleeved on the outside of the lower shell. The load-bearing component is disposed on the upper shell. The lifting component includes a rack, a gear, and a driving component. The rack is fixedly connected to the lower shell and located on one side of the lower shell. The gear is rotatably connected to the upper shell and meshes with the rack. The driving component is disposed on the upper shell and is used to drive the gear to rotate.

[0007] The load-bearing component includes a bracket and a support plate. The bracket is detachably connected to the upper housing by bolts, and the support plate is fixedly connected to the bracket and disposed on the bracket.

[0008] The lower housing has a guide groove on one side; the upper housing has a guide protrusion on the inner side of the upper housing and the guide protrusion extends into the guide groove.

[0009] The driving component includes a first rotating shaft, a first bevel gear, a second bevel gear, and a drive shaft. The first rotating shaft is fixedly connected to the gear and is located on one side of the gear. The first bevel gear is fixedly connected to the first rotating shaft and is located at the end of the first rotating shaft away from the gear. The drive shaft is rotatably connected to the upper housing and is located inside the upper housing. The second bevel gear is fixedly connected to the drive shaft and meshes with the first bevel gear.

[0010] The driving component further includes a worm gear, a worm, and a turntable. The worm gear is fixedly connected to the driving shaft and is sleeved on the driving shaft. The turntable is rotatably connected to the upper housing and is located on one side of the upper housing. The worm is fixedly connected to the turntable and meshes with the worm gear.

[0011] The computer system integration service network cabinet with expansion structure further includes an upper door and a lower door. The upper door is rotatably connected to the upper housing and is located on one side of the upper door. The lower door is rotatably connected to the lower housing and is located on one side of the lower housing.

[0012] A sealing gasket is installed on the side of the upper door body near the lower door body, and the sealing gasket is in contact with the lower door body.

[0013] This invention discloses a network cabinet for computer system integration services with an expandable structure. A drive turntable rotates a worm gear, which in turn drives a worm wheel and a drive shaft. The drive shaft, via first and second bevel gears on both sides, causes the first rotating shafts on both sides to drive the gears to rotate synchronously. The gears smoothly ascend or descend along racks fixed to both sides of the lower housing, thus achieving effortless lifting and lowering of the upper housing relative to the lower housing. Due to the use of worm gear transmission, its self-locking characteristic allows the upper housing to remain stably at any height without relying on friction for locking, significantly improving load-bearing safety. Simultaneously, the rigid meshing of the gears and racks on both sides ensures height synchronization during lifting, avoiding jamming and tilting problems caused by asynchrony on both sides during manual pulling. This invention features a compact structure, convenient operation, and reliable, effectively solving the problems of laborious and asynchronous manual lifting and lowering in existing technologies.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] First embodiment: Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of a network cabinet for computer system integration services with an expansion structure according to the first embodiment of the present invention. Figure 2 This is a schematic diagram of the lifting assembly according to the first embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the driving component according to the first embodiment of the present invention.

[0022] This invention provides a network cabinet for computer system integration services with an expandable structure, including an upper shell 101, a lower shell 102, a load-bearing component 103, and a lifting component 104. The lifting component 104 includes a rack 119, a gear 120, and a drive component 121. Through the meshing transmission between the gear 120 and the rack 119, and the synchronous drive of the gears 120 on both sides by the drive component 121, the problem of manual pulling of the expansion shell in the prior art, which is laborious and causes jamming and tilting due to asynchrony on both sides, is solved. It is understood that the above solution can be used in scenarios where data centers or system integration rooms need to dynamically expand the capacity of network equipment.

[0023] In this specific embodiment, the upper housing 101 is slidably connected to the lower housing 102 and sleeved on the outside of the lower housing 102. The bearing assembly 103 is disposed on the upper housing 101. The rack 119 is fixedly connected to the lower housing 102 and located on one side of the lower housing 102. The gear 120 is rotatably connected to the upper housing 101 and meshes with the rack 119. The driving member 121 is disposed on the upper housing 101 and is used to drive the gear 120 to rotate. Multiple bearing assemblies 103 are provided, and the lower housing 102 also has a bearing assembly 103 inside. The bearing assembly 103 is used to support and fix network equipment such as servers, switches, and patch panels. Two gears 120 and two racks 119 are provided, respectively located on the left and right sides of the upper housing 101. The driving member 121 can drive the two gears 120 to rotate synchronously.

[0024] In use, initially, the upper housing 101 is fitted over the lower housing 102 and is in its lowest position. When the installation capacity of the cabinet needs to be increased, the operator drives the two gears 120 to rotate synchronously through the drive component 121. The gears 120 climb upward along the racks 119 fixed to both sides of the lower housing 102, causing the upper housing 101 to move vertically upward relative to the lower housing 102. During the upward movement, the overlap between the upper housing 101 and the lower housing 102 gradually decreases, and the effective vertical communication area between the internal space of the upper housing 101 and the internal space of the lower housing 102 increases accordingly. After the body 101 rises to a predetermined height, the upper housing 101 is fixed at that height. At this time, the vertical distance between the load-bearing component 103 in the upper housing 101 and the load-bearing component 103 in the lower housing 102 increases. If it is necessary to further increase the expansion capacity, the upper housing 101 can be driven to rise to a higher position. Conversely, when it is necessary to restore to the standard height or transport cabinet, the drive component 121 is rotated in the opposite direction until it is reset to the lowest position. At this time, the overall height of the cabinet is reduced, which is convenient for handling and storage. The present invention drives the gear 120 to rotate, so that the gear 120 climbs or descends on the rack 119, thereby adjusting the internal space of the cabinet and achieving the purpose of convenient adjustment.

[0025] The supporting component 103 includes a bracket 105 and a tray 106. The bracket 105 is detachably connected to the upper housing 101 by bolts. The tray 106 is fixedly connected to the bracket 105 and is disposed on the bracket 105. Multiple brackets 105 are disposed on one tray 106. The bracket 105 has an L-shaped structure and is provided with through holes. Bolts pass through the through holes on the bracket 105 and are threadedly connected to the upper housing 101 or the lower housing 102 to realize the installation of the tray 106.

[0026] Secondly, the lower housing 102 has a guide groove 107, which is disposed on one side of the lower housing 102; the upper housing 101 has a guide protrusion 108, which is disposed on the inner side of the upper housing 101 and extends into the guide groove 107; there are multiple guide grooves 107 and multiple guide protrusions 108, and the guide grooves 107 guide the movement of the guide protrusions 108, thereby guiding the lifting and lowering of the upper housing 101 and improving the stability of the upper housing 101 during lifting and lowering.

[0027] Meanwhile, the driving component 121 includes a first rotating shaft 109, a first bevel gear 110, a second bevel gear 111, and a driving shaft 112. The first rotating shaft 109 is fixedly connected to the gear 120 and is located on one side of the gear 120. The first bevel gear 110 is fixedly connected to the first rotating shaft 109 and is located at the end of the first rotating shaft 109 away from the gear 120. The driving shaft 112 is rotatably connected to the upper housing 101 and is located inside the upper housing 101. The second bevel gear 111 is fixedly connected to the driving shaft 112 and meshes with the first bevel gear 110.

[0028] In addition, the driving component 121 also includes a worm gear 113, a worm 114, and a turntable 115. The worm gear 113 is fixedly connected to the driving shaft 112 and is sleeved on the driving shaft 112. The turntable 115 is rotatably connected to the upper housing 101 and is located on one side of the upper housing 101. The worm 114 is fixedly connected to the turntable 115 and meshes with the worm gear 113.

[0029] Two second bevel gears 111 are provided, located at both ends of the drive shaft 112. Two first bevel gears 110 and two first rotating shafts 109 are provided. The two first rotating shafts 109 are respectively connected to the two gears 120, and the two first bevel gears 110 are respectively connected to the two first rotating shafts 109. The two second bevel gears 111 mesh with the two first bevel gears 110 in a one-to-one correspondence. When the operator rotates the turntable 115, the turntable 115 drives the worm gear 114 to rotate. The worm gear 114 drives the worm wheel 113 and the drive shaft 112 to rotate. The second bevel gears 111 at both ends of the drive shaft 112 rotate synchronously, thereby driving the two first bevel gears 110 and the two first rotating shafts 109 meshing with them to rotate synchronously. Finally, the two gears 120 climb or descend along the rack 119 at the same speed. Because the transmission between the worm gear 113 and the worm 114 has a self-locking characteristic, when the turntable 115 stops rotating, the upper housing 101 can automatically lock at the current height without the need for an additional locking device, effectively avoiding the risk of accidental slippage due to vibration or heavy load.

[0030] Then, the computer system integration service network cabinet with expansion structure also includes an upper door 116 and a lower door 117. The upper door 116 is rotatably connected to the upper housing 101 and is located on one side of the upper door 116; the lower door 117 is rotatably connected to the lower housing 102 and is located on one side of the lower housing 102.

[0031] Finally, a sealing gasket 118 is installed on the side of the upper door body 116 near the lower door body 117, and the sealing gasket 118 is in contact with the lower door body 117.

[0032] Both the upper door 116 and the lower door 117 are single-door structures, and their rotation axes are located on the same side. When the upper housing 101 rises to the extended position, the upper door 116 moves upward with the upper housing 101, forming a gap between the upper door 116 and the lower door 117. The sealing gasket 118 is fixed to the lower end of the upper door 116. When the upper housing 101 is at any height, the lower edge of the sealing gasket 118 always remains in contact with the upper edge of the lower door 117, thereby sealing the gap between the upper door 116 and the lower door 117 and preventing external dust or foreign objects from entering the cabinet. At the same time, the sealing gasket 118 is made of flexible rubber and can undergo elastic deformation with the rise and fall of the upper housing 101 to ensure the continuity of contact and the sealing effect.

[0033] Second embodiment: Based on the first embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the locking component in the second embodiment. The turntable 115 in this embodiment includes a disc body 201, a rotating rod 202 and a locking component 203. The locking component 203 includes a locking rod 204 and a spring 205.

[0034] In this specific embodiment, the disc body 201 is rotatably connected to the upper housing 101 and fixedly connected to the worm gear 114; the rotating rod 202 is rotatably connected to the disc body 201 and is disposed on the disc body 201; the locking member 203 is disposed on the disc body 201; a torsion spring (not shown in the figure) is disposed between the rotating rod 202 and the disc body 201, one end of the torsion spring being fixedly connected to the rotating rod 202 and the other end being fixedly connected to the disc body 201. The rotating rod 202 has a retracted position and an extended position: in the retracted position, the rotating rod 202 is retracted into a groove on the surface of the disc body 201 to reduce space occupation and avoid accidental collisions; in the extended position, the rotating rod 202 extends outward against the elastic force of the torsion spring, forming a perpendicular angle with respect to the disc body 201, thereby increasing the rotation arm and making it easier for the operator to hold and easily rotate the disc body 201.

[0035] The locking rod 204 is rotatably connected to the disc body 201 and axially passes through the worm gear 114; the two ends of the spring 205 are respectively connected to the locking rod 204 and the disc body 201; the rotating rod 202 has a driving protrusion, which is located on the side of the rotating rod 202 near the locking rod 204; the lower housing 102 is provided with a plurality of locking grooves, which cooperate with the locking rod 204. When the rotating rod 202 rotates from the unfolded position to the retracted position under the action of the torsion spring, the driving protrusion moves synchronously with the rotating rod 202; when the rotating rod 202 is completely retracted into the groove on the surface of the disc body 201, the driving protrusion aligns with the end of the locking rod 204 and pushes the locking rod 204 against the elastic force of the spring 205 to move axially; the locking rod 204 axially passes through the disc body 201. The worm gear 114 extends into the locking groove at the corresponding position on the lower housing 102, thereby locking the rotation angle of the disc 201 and the worm gear 114 to prevent the upper housing 101 from accidentally rising or falling under its own weight or external force. Multiple locking grooves are distributed vertically along the side wall of the lower housing 102, corresponding to different lifting height positions of the upper housing 101. When the height of the upper housing 101 needs to be adjusted, the operator manually pulls the rotating rod 202 outward from its retracted position. Driven by the torsion spring, the rotating rod 202 springs up to the unfolded position. During this process, the driving protrusion disengages from the locking rod 204, and the locking rod 204 exits the locking groove under the reset action of the spring 205, releasing the locked state. The operator can then freely rotate the disc 201 via the rotating rod 202 to perform lifting and lowering operations.

[0036] This invention relates to a network cabinet for computer system integration services with an expandable structure. Through the meshing transmission of double-sided gears 120 and racks 119, it achieves smooth, effortless, and synchronous lifting of the upper housing 101 relative to the lower housing 102, solving the problems of laborious manual pulling and jamming / tilting caused by asynchronous operation on both sides in existing technologies. Utilizing the self-locking characteristics of the worm gear 113 and worm 114, the upper housing 101 can automatically lock at any height without the need for additional locking devices, significantly improving load-bearing safety and operational convenience. The turntable 115 is equipped with a retractable rotating rod 202 and a locking component 203, ensuring effortless lifting and preventing the rotating rod 202 from protruding and causing space occupation or collisions. Simultaneously, the locking rod 204, in cooperation with the locking groove of the lower housing 102, provides independent mechanical locking, forming a double safety guarantee. This invention features a compact structure, effortless operation, flexible expansion, and reliable safety, making it suitable for scenarios requiring dynamic expansion of network equipment capacity, such as data centers and system integration rooms. It has good practical value and promising prospects for widespread application.

[0037] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
