Description

Technical Field

[0001] The invention belongs to the technical field of communication boxes, and in particular relates to a communication box that is easy to install. Background Art

[0002] A communications enclosure is a metal or composite housing used to house communications equipment. It is commonly found in telecommunications rooms, base stations, and switch rooms. It protects internal equipment (such as switches, routers, and servers) from the outside world while facilitating management and maintenance.

[0003] The existing communication box is provided with a T-shaped slot on the wall, and two card plates pass through the through slot on the inner wall of the installation box. One end of the two card plates passing through the through slot is respectively connected to the two movable plates in the installation box. When installing the installation box on the wall, it is only necessary to insert the card plates into the T-shaped slot of the wall while hanging the installation box on the wall, and then the two movable plates are used to drive the two card plates to move and clamp them into the T-shaped slot in the through slot, so that the installation of the installation box can be realized. The operation is simple and convenient.

[0004] Although the existing box can be installed by engaging the T-slot with the card plate, the card plate still needs to be manually driven and clamped to the T-slot, which makes the installation more cumbersome. When working at high altitude or in a narrow space, manual operation of the card plate may cause problems such as difficulty in positioning or fatigue. Uneven force may cause inadequate clamping, thereby affecting the installation stability of the box.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a communication box that is easy to install to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the deficiencies in the prior art, an object of the embodiments of the present invention is to provide a communication box that is easy to install, so as to solve the problems in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A communication box that is easy to install, comprising a communication box, a fixed back plate and a fixed card block, wherein the fixed card block is fixed to a wall, and the fixed back plate is distributed on the back side of the communication box. The fixed back plate mainly comprises a connecting end, a bent end and an insertion end. The connecting end on the fixed back plate is fixedly connected to the back side of the communication box, and the insertion end on the fixed back plate cooperates with an insertion slot provided on the outside of the fixed card block. The invention also includes:

[0009] A control mechanism, comprising a drive assembly, a rotating shaft, a non-return assembly, and a connecting assembly. The drive assembly is mounted on the inner side of the fixed block and is connected to the rotating shaft rotatably mounted on the fixed block. A non-return assembly is mounted in the middle of the rotating shaft. One end of the non-return assembly extends into the insertion slot and intermittently cooperates with the insertion end on the fixed backplate. Connecting assemblies are symmetrically mounted on both ends of the rotating shaft.

[0010] A limiting mechanism, wherein the limiting mechanism is vertically slidably installed on the inner side of the fixed block, the bottom of the limiting mechanism is connected to one end of the connecting assembly, the left and right ends of the limiting mechanism are respectively slidably matched with the linear guide groove and the inclined guide groove opened on the left and right sides of the fixed block, the inclined guide groove is located above the linear guide groove and is connected to it, and the inclined guide groove is inclined toward the direction close to the outside of the fixed block.

[0011] As a further technical solution of the present invention, a vertical sliding groove is vertically opened on the inner side of the fixed block for the limiting mechanism to slide vertically, and an installation groove is opened in the middle of the fixed block for the anti-return component to be installed, and the installation groove connects the inner side of the fixed block with the insertion groove thereon.

[0012] As a further technical solution of the present invention, the anti-return assembly includes a anti-return ratchet, a anti-return block, a mounting shaft and a hook-shaped spring piece. The anti-return ratchet is fixed on the rotating shaft and is concentric with it. The anti-return block is rotatably installed in the mounting groove through the mounting shaft. One end of the anti-return block is located on the inner side of the fixed block and cooperates with the anti-return ratchet. The other end of the anti-return block extends into the insertion slot and intermittently cooperates with the insertion end on the fixed back plate. One end of the hook-shaped spring piece is installed on the inner side of the fixed block, and the other end of the hook-shaped spring piece is connected to one end of the anti-return block.

[0013] As a further technical solution of the present invention, a groove is provided on one side of the insertion end of the fixed backplate, and the thickness of the groove is greater than the length of the anti-return block extending into the insertion slot. When the bottom of the fixed backplate contacts the anti-return block, it drives the anti-return block to rotate and releases the restriction on the rotating shaft; when the groove moves down to a position matching the anti-return block, the anti-return block rotates under the drive of the hook-shaped spring piece and restores the restriction on the rotating shaft.

[0014] As a further technical solution of the present invention, the connecting assembly includes a spiral spring piece, a reel and a connecting rope, one end of the spiral spring piece is connected to the rotating shaft, the other end of the spiral spring piece is connected to the fixed block, the reel is concentrically fixed on the rotating shaft, a connecting rope is wound around the reel, and one end of the connecting rope is connected to the limiting mechanism.

[0015] As a further technical solution of the present invention, the driving assembly includes a rotating part, gear 1 and gear 2, the rotating part is located outside the left or right side of the fixed block, the rotating part is coaxial with the gear, the gear 1 is rotatably installed on the inner side of the fixed block, and the gear 1 is engaged with gear 2 concentrically fixed on the rotating shaft.

[0016] As a further technical solution of the present invention, the limiting mechanism includes a slide, spring 1, a limiting plate, a guide wheel and spring 2. One side of the slide is installed in the vertical slide groove. A horizontal slide groove is provided on the slide. The bottom of the slide is connected to the inner side of the fixed block through spring 1. The limiting plate is horizontally slidably installed on the horizontal slide groove. One end of the limiting plate intermittently cooperates with the bent end of the fixed back plate. Guide wheels that slide with the linear guide groove and the inclined guide groove are fixed on both sides of the limiting plate. One side of the limiting plate is connected to the slide through spring 2.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By engaging the fixed back panel and the fixed card block to trigger the control mechanism and the limit mechanism, installation can be completed quickly without additional tools, greatly reducing installation time and significantly improving installation efficiency and quality. The insertion slot on the fixed card block cooperates with the fixed back panel to form a horizontal limit and prevent the box from lateral displacement. Under the action of the inclined guide groove, the limit mechanism moves up in a curved trajectory to the top of the bent end to form a vertical limit, thereby achieving rapid installation of the communication box. The double limit design can keep the box stable in complex environments such as strong winds or earthquakes, reducing the risk of internal equipment failure. The modular design of the fixed card block and the fixed back panel can adapt to communication boxes of different specifications and sizes. It only needs to adjust the dimensional parameters of the fixed back panel to meet diverse needs. In addition, the combined design of the inclined guide groove and the straight guide groove can adapt to different installation angle requirements. Whether it is a vertical wall, an inclined slope or a special structural surface, it can achieve reliable installation, expanding the application scenarios of the communication box.

[0019] When the communication box needs to be disassembled, the drive assembly drives the rotating shaft to rotate, and the connecting assembly in the stored force state cooperates with the rotating shaft to drive the limiting mechanism and release the vertical limit of the fixed backplate. In this way, the high-altitude box can be quickly disassembled to the ground for inspection, shortening the equipment downtime and making the maintenance of communication equipment more convenient and efficient.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0034] like Figures 1 to 10 As shown, as an embodiment of the present invention, an easy-to-install communication box 100 is provided, including a communication box 100, a fixed back panel 200 and a fixed card block 300, wherein the fixed card block 300 is fixed to the wall, and the fixed back panel 200 is distributed on the back side of the communication box 100. The fixed back panel 200 is mainly composed of a connecting end 210, a bent end 220 and an insertion end 230. The connecting end 210 on the fixed back panel 200 is fixedly connected to the back side of the communication box 100, and the insertion end 230 on the fixed back panel 200 cooperates with the insertion slot 310 provided on the outer side of the fixed card block 300. The invention also includes:

[0035] The control mechanism 400 includes a drive assembly 410, a rotating shaft 420, a check assembly 430, and a connecting assembly 440. The drive assembly 410 is mounted on the inner side of the fixed block 300 and is connected to the rotating shaft 420 rotatably mounted on the fixed block 300. The check assembly 430 is mounted in the middle of the rotating shaft 420. One end of the check assembly 430 extends into the insertion slot 310 and intermittently engages with the insertion end 230 on the fixed backplate 200. The connecting assemblies 440 are symmetrically mounted at both ends of the rotating shaft 420.

[0036] The limiting mechanism 500 is vertically slidably installed on the inner side of the fixed block 300, and the bottom of the limiting mechanism 500 is connected to one end of the connecting component 440. The left and right ends of the limiting mechanism 500 are respectively slidably matched with the linear guide groove 330 and the inclined guide groove 340 opened on the left and right sides of the fixed block 300. The inclined guide groove 340 is located above the linear guide groove 330 and is connected to it. The inclined guide groove 340 is inclined toward the direction close to the outside of the fixed block 300.

[0037] In the initial state, the limiting mechanism 500 slides with the linear guide groove 330 on the fixed block 300 and is hidden inside the fixed block 300. The anti-return assembly 430 restricts the rotating shaft 420 and keeps it in a stationary state. The connecting assembly 440 limits the limiting mechanism 500 and keeps it in a power storage state.

[0038] When the locking mechanism 500 is in the state of being moved, the locking mechanism 500 is locked and the locking mechanism 500 is unlocked, so that the locking mechanism 500 is unlocked and the locking mechanism 500 is unlocked. The box body 100 is displaced laterally, and the limiting mechanism 500 cooperates with the fixed card block 300 to complete the vertical limitation of the fixed back panel 200. The double limiting design enables the communication box body 100 to remain in a firmly installed state in complex environments (such as strong winds, earthquakes or traffic vibration areas), reducing the risk of failure of internal equipment. The plug-in of the fixed back panel 200 and the fixed card block 300 triggers the linkage of the control mechanism 400 and the limiting mechanism 500, and the installation action can be completed without additional tools, thereby realizing the rapid installation of the communication box body 100, greatly reducing the installation time, and significantly improving the installation efficiency and installation quality of the communication box body 100. The modular design of the fixed card block 300 and the fixed back panel 200 can adapt to communication boxes 100 of different specifications and sizes. It is only necessary to adjust the size parameters of the fixed back panel 200 to meet diverse needs. In addition, the combined design of the inclined guide groove 340 and the linear guide groove 330 can adapt to different installation angle requirements. Whether it is a vertical wall, an inclined slope or a special structure surface, reliable installation can be achieved, expanding the application scenarios of the communication box 100.

[0039] like Figures 2 to 7 As shown, as a preferred embodiment of the present invention, a vertical slide groove 320 for vertical sliding of the limiting mechanism 500 is vertically opened on the inner side of the fixed block 300, and an installation groove 350 for installing the anti-return component 430 is opened in the middle of the fixed block 300. The installation groove 350 can connect the inner side of the fixed block 300 with the insertion groove 310 thereon.

[0040] like Figures 2 to 9As shown, as a preferred embodiment of the present invention, the anti-return assembly 430 includes a anti-return ratchet 431, a anti-return block 432, a mounting shaft 433 and a hook-shaped spring piece 434. The anti-return ratchet 431 is fixed on the rotating shaft 420 and is concentric therewith. The anti-return block 432 is rotatably installed in the mounting groove 350 through the mounting shaft 433. One end of the anti-return block 432 is located on the inner side of the fixed block 300 and cooperates with the anti-return ratchet 431. The other end of the anti-return block 432 extends into the insertion groove 310 and intermittently cooperates with the insertion end 230 on the fixed backplate 200. One end of the hook-shaped spring piece 434 is installed on the inner side of the fixed block 300, and the other end of the hook-shaped spring piece 434 is connected to one end of the anti-return block 432.

[0041] When the locking cam 432 is engaged with the locking cam 431, the locking cam 432 is engaged with the locking cam 431, and the locking cam 432 is engaged with the locking cam 431, thereby limiting the rotation of the shaft 420 and making it only rotate in one direction. When the fixing back plate 200 is engaged with the locking cam 432, the fixing back plate 200 drives the locking cam 432 to rotate in the opposite direction, separating it from the locking cam 431, thereby releasing the restriction on the shaft 420 and making the shaft 420 free. At this time, the connecting assembly 440 and the limiting mechanism 500 in the stored force state can release their own elastic force, so that the limiting mechanism 500 can quickly move upward and complete the vertical limitation of the fixing back plate 200, so that the fixing block 300 is stably connected to the fixing back plate 200, thereby improving the installation stability of the communication box 100.

[0042] When the insertion end 230 of the fixed backplate 200 fully enters the insertion slot 310, the fixed backplate 200 is separated from the anti-return block 432, so that the anti-return block 432 is driven by the hook-shaped spring piece 434 to resume cooperation with the anti-return ratchet 431, thereby restoring the restriction on the rotating shaft 420; when the communication box 100 needs to be dismantled, the worker drives the rotating shaft 420 to rotate through the driving component 410, and the rotating shaft 420 drives the limiting mechanism 500 to move downward through the connecting component 440 and releases the vertical restriction on the fixed backplate 200, so that the fixed backplate 200 can be quickly pulled out from the insertion slot 310, thereby realizing the rapid disassembly of the communication box 100, so that the communication box 100 located at a high altitude can be disassembled to the ground or a work surface, which is convenient for workers to inspect or replace the communication equipment inside the communication box 100, shortening the downtime of the equipment and making the maintenance of the communication equipment more convenient and efficient.

[0043] like Figures 2 to 9As shown, as a preferred embodiment of the present invention, a groove 240 is provided on one side of the insertion end 230 on the fixed back plate 200, and the thickness of the groove 240 is greater than the length of the anti-return block 432 extending into the insertion groove 310. When the bottom of the fixed back plate 200 first contacts the anti-return block 432, it can drive the anti-return block 432 to rotate, thereby releasing the restriction on the rotating shaft 420, and when the anti-return block 432 rotates to a certain angle, it will slide with the side wall of the insertion end 230, so that the insertion end 230 can fully enter the insertion groove 310 to ensure fixation. The connection strength between the back panel 200 and the fixed block 300; when the groove 240 moves down to a position matching the anti-return block 432, the anti-return block 432 rotates under the drive of the hook-shaped spring piece 434. After the fixed back panel 200 and the fixed block 300 are stably connected, the anti-return block 432 can restore the restriction on the rotating shaft 420. In this way, during the disassembly of the communication box 100, the driving component 410 can facilitate the unidirectional drive of the rotating shaft 420 better and faster to avoid rotation, etc., thereby improving the disassembly efficiency of the communication box 100 and reducing the disassembly time.

[0044] like Figures 2 to 9 As shown, as a preferred embodiment of the present invention, the connecting component 440 includes a spiral spring piece 441, a reel 442 and a connecting rope 443, one end of the spiral spring piece 441 is connected to the rotating shaft 420, the other end of the spiral spring piece 441 is connected to the fixed block 300, the reel 442 is concentrically fixed on the rotating shaft 420, a connecting rope 443 is wound around the reel 442, and one end of the connecting rope 443 is connected to the limiting mechanism 500.

[0045] In the initial state, the spiral spring piece 441 is in an uncharged state, and one end of the connecting rope 443 is wound onto the reel 442. When the rotating shaft 420 is in a free state, the limiting mechanism 500 quickly moves upward by releasing its own elastic force and drives one end of the connecting rope 443 to move upward. The upward movement of one end of the connecting rope 443 can drive the reel 442 to rotate, and the reel 442 drives the rotating shaft 420 to rotate. The rotating shaft 420 drives one end of the spiral spring piece 441 to rotate and keep it in a charged state. In this way, the upward movement of the connecting rope 443 can be controlled to prevent it from being separated from the reel 442.

[0046] When the driving component 410 drives the rotating shaft 420 to rotate in the opposite direction, the spring piece in the stored force state can release its own elastic force and help the driving component 410 to drive the rotating shaft 420 together. This can reduce the driving force of the driving component 410, making it easier for workers to disassemble the communication box 100 better and faster, further reducing the difficulty of disassembling the communication box 100 and improving the convenience of the communication box 100.

[0047] In a preferred embodiment, the connecting rope 443 is preferably a rust-proof or corrosion-resistant steel wire rope, which can extend the service life of the connecting component 440 and thereby improve the installation stability of the communication box 100.

[0048] like Figures 2 to 9 As shown in FIG. 4 , as a preferred embodiment of the present invention, the driving assembly 410 includes a rotating member 411, a gear 1 412, and a gear 2 413. The rotating member 411 is located outside the left or right side of the fixed block 300. The rotating member 411 is coaxial with the gear 1 412. The gear 1 412 is rotatably mounted on the inner side of the fixed block 300. The gear 1 412 is meshed with the gear 2 413 concentrically fixed on the rotating shaft 420.

[0049] When the communication box 100 needs to be dismantled, the worker drives gear 1 412 to rotate through the rotating part 411, and gear 1 412 drives the rotating shaft 420 to rotate through gear 2 413. The rotating shaft 420 drives the reel 442 to rotate and completes the winding of the connecting rope 443. The reel 442 can drive the limiting mechanism 500 to move downward and release the vertical limit of the fixed backplate 200 by winding the connecting rope 443, so that the fixed backplate 200 can be quickly pulled out from the insertion slot 310, thereby realizing the rapid disassembly of the communication box 100, so that the communication box 100 located at a high altitude can be disassembled to the ground or a work surface, which is convenient for workers to inspect or replace the communication equipment inside the communication box 100, shortening the downtime of the equipment and making the maintenance of the communication equipment more convenient and efficient.

[0050] In a preferred embodiment, the rotating part 411 preferably adopts a circular block structure, and a slot that cooperates with the handle can be opened on one side of the rotating part 411. The handle can be a hexagonal handle. In this case, the slot is a hexagonal slot, which can facilitate workers to drive gear 1 412 through the hexagonal handle, thereby completing the rapid disassembly of the communication box 100.

[0051] like Figures 2 to 10As shown, as a preferred embodiment of the present invention, the limiting mechanism 500 includes a slide 510, a spring 1 520, a limiting plate 530, a guide wheel 540 and a spring 2 550. One side of the slide 510 is installed in the vertical slide groove 320. The slide 510 is provided with a horizontal slide groove 511. The bottom of the slide 510 is connected to the inner side of the fixed block 300 through the spring 1 520. The limiting plate 530 is horizontally slidably installed on the horizontal slide groove 511. One end of the limiting plate 530 is intermittently matched with the bent end 220 of the fixed back plate 200. Guide wheels 540 that slide with the linear guide groove 330 and the inclined guide groove 340 are fixed on both sides of the limiting plate 530. One side of the limiting plate 530 is connected to the slide 510 through the spring 2 550.

[0052] When the guide wheel 540 slides with the linear guide groove 330, the limiting plate 530 can squeeze the second spring 550 by cooperating with the vertical slide groove 320 and the slide seat 510, so that the second spring 550 is in a force storage state. At the same time, the limiting plate 530 is hidden in the fixed block 300 and is located on one side of the fixed back plate 200.

[0053] When the guide wheel 540 slides with the inclined guide groove 340, the spring 2 550 releases its own elastic force and drives the limit plate 530 to move horizontally on the slide 510, so that the limit plate 530 also slides horizontally while moving up with the slide 510, thereby making the limit plate 530 move up in a curved trajectory to above the bent end 220 and complete the vertical limitation of the fixed back plate 200. The fixed block 300 cooperates with the insertion groove 310 to complete the horizontal limitation of the fixed back plate 200, preventing the communication box 100 from lateral displacement. The double limit design enables the communication box 100 to remain firmly installed in complex environments (such as strong winds, earthquakes or traffic vibration areas), reducing the risk of failure of internal equipment.

[0054] The elastic force of the first spring 520 is greater than the elastic force of the second spring 550 and the spiral spring piece 441 combined.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
