Description

Technical Field

[0001] This invention relates to the field of gateway technology, and more specifically, to a wall-mounted gateway box. Background Technology

[0002] A gateway box is a connector and protocol converter used in network connections. It can support the conversion between different protocols and realize the interconnection between networks with different protocols. It is widely used in the field of communications.

[0003] Traditional gateway boxes are mostly installed directly in suitable locations indoors, inevitably leading to problems such as space occupation and susceptibility to intentional or unintentional damage. To address this, wall-mounted gateway boxes have emerged. These boxes can be installed on indoor walls, effectively solving the problems of space occupation and vulnerability to damage. For example, patent document CN212660183U discloses a wall-mounting mechanism for a smart gateway. The technical solution disclosed in this patent document uses a wall-mounting plate as a fixing component. During actual installation, the wall-mounting plate is first fixed to a suitable location on the indoor wall, and then the gateway box is fixed to the wall-mounting plate, thus achieving a secure installation of the gateway box on the wall.

[0004] However, in practical applications, when the gateway box is installed high on the wall, a malfunction often requires personnel to use auxiliary devices such as a folding ladder to repair and troubleshoot the box. This process is cumbersome and inefficient. Therefore, it is necessary to design a new wall-mounted gateway box to facilitate repair and troubleshooting when a malfunction occurs. Summary of the Invention

Detailed Implementation

[0040] Example 1

[0041] Please refer to Figures 1 to 5 This embodiment provides a wall-mounted gateway box to overcome at least the technical problems of inconvenient maintenance and debugging when existing wall-mounted gateway boxes installed at high positions on the wall malfunction. Specifically, the wall-mounted gateway box includes a gateway box body 10, a wall-mounting plate 20, a supporting mechanism 30, and a traction mechanism 40. It is understood that the gateway box body 10 mentioned in this embodiment can be a conventional video gateway or sensor gateway, etc., in the prior art.

[0042] In this embodiment, combined with Figure 5 As shown, the wall-mounted panel 20 serves as a fastener. Corresponding fixing holes can be provided on the wall-mounted panel 20 so that it can be fixed to the appropriate position on the wall using fasteners such as bolts during the actual installation process. Once the wall-mounted panel 20 is fixedly installed, it is usually not disassembled.

[0043] In this embodiment, the supporting mechanism 30 is used to support the gateway box body 10. Please refer to... Figure 2The support mechanism 30 includes a support plate 31 and two clamping units 32. The gateway box body 10 is supported on the top surface of the support plate 31. The two clamping units 32 are symmetrically arranged on both sides of the gateway box body 10 so as to firmly clamp the gateway box body 10 onto the support plate 31 through the two clamping units 32.

[0044] Specifically, continue to refer to Figure 2 The clamping unit 32 includes a fixed plate 321, a movable plate 322, and an elastic element 323. The fixed plate 321 is fixedly disposed on the top surface of the support plate 31. Preferably, the fixed plate 321 is disposed at the edge of the top surface of the support plate 31. The movable plate 322 is slidably disposed on the top surface of the support plate 31 and located inside the fixed plate 321 (i.e., on the side closer to the gateway box body 10). For example, a horizontal groove can be provided on the top surface of the support plate 31, and the bottom of the movable plate 322 can be slidably disposed in the horizontal groove to enable the movable plate 322 to slide on the top surface of the support plate 31. The elastic element 323 is disposed between the fixed plate 321 and the movable plate 322. One end of the elastic element 323 is connected to the fixed plate 321, and the other end of the elastic element 323 is connected to the movable plate 322. It is understandable that in actual implementation, each clamping unit 32 can have multiple elastic elements 323 to increase the clamping force applied by the movable plate 322 to the gateway box body 10, making the gateway box body 10 more secure after being clamped. For example, in this embodiment, each clamping unit 32 has two elastic elements 323.

[0045] With this configuration, when it is necessary to fix the gateway box body 10 onto the support plate 31, the movable plates 322 of the two clamping units 32 are first pulled in opposite directions, so that the distance between the two movable plates 322 is greater than the width of the gateway box body 10. During this process, the elastic element 323 contracts to store a spring force. After the gateway box body 10 is placed on the support plate 31 between the two movable plates 322, the two movable plates 322 are released. At this time, the elastic element 323 contracts, and the two movable plates 322 move in opposite directions under the action of the corresponding elastic element 323, so as to firmly clamp and fix the gateway box body 10 onto the support plate 31 through the two movable plates 322. This method can be applied to clamping and fixing gateway box bodies 10 of various widths.

[0046] It should be noted that, in actual implementation, a protective pad can be installed on the side of the movable plate 322 facing the gateway box body 10 to prevent the movable plate 322 from scratching the gateway box body 10 when it comes into direct contact with it. Meanwhile, in conjunction with... Figure 2As shown, the elastic element 323 includes a telescopic column 3231 and a clamping spring 3232. The fixed end of the telescopic column 3231 is connected to the fixed plate 321, and the free end of the telescopic column 3231 is connected to the movable plate 322. The clamping spring 3232 is sleeved on the outer wall of the telescopic column 3231. One end of the clamping spring 3232 is connected to the fixed plate 321, and the other end of the clamping spring 3232 is connected to the movable plate 322. With this configuration, based on the clamping force provided by the clamping spring 3232 to clamp the gateway box body 10, when the movable plate 322 slides on the support plate 31, the telescopic column 3231 can extend and retract synchronously to play a good limiting and guiding role, thereby improving the stability of the movable plate 322 when sliding on the support plate 31.

[0047] In addition, the clamping unit 32 in this embodiment also includes a pressure plate 324, which, in combination with Figure 2 and Figure 3 As shown, the pressure plate 324 is horizontally arranged, with one side of the pressure plate 324 extending towards the gateway box body 10. A reset post 325 is provided at the bottom of the other side of the pressure plate 324. A reset groove adapted to the reset post 325 is provided on the top surface of the movable plate 322. A reset spring 326 is vertically arranged in the reset groove. The bottom of the reset post 325 extends into the reset groove and is connected to the reset spring 326. Based on this configuration, when it is necessary to fix the gateway box body 10, the pressure plate 324 can be pulled upward according to the height of the gateway box body 10, so that the distance from the bottom surface of the pressure plate 324 to the top surface of the support plate 31 is greater than the height of the gateway box body 10. During this process, the return spring 326 is stretched to store a spring force. After the gateway box body 10 is placed on the support plate 31, the pressure plate 324 is released. At this time, the return spring 326 contracts, and the pressure plate 324 moves downward under the action of the return spring 326 until it contacts the top surface of the gateway box body 10. Thus, the support plate 31 and the pressure plate 324 restrict the degree of freedom of the gateway box body 10 in the vertical direction, further improving the stability of the gateway box body 10 after it is clamped and fixed on the support plate 31. This method can be applied to fixing gateway box bodies 10 of various different heights.

[0048] In this embodiment, the traction mechanism 40 is used to drive the supporting mechanism 30 and the gateway box body 10 to move vertically, so as to adjust the position of the gateway box body 10 in the vertical direction as needed, which is beneficial for later maintenance and debugging. Specifically, please refer to... Figure 1 The traction mechanism 40 includes a stranded wire reel 41, a drive unit 42, and two traction units 43. The stranded wire reel 41 is rotatably mounted on the top surface of the wall-mounted panel 20. The drive unit 42 is used to drive the stranded wire reel 41 to rotate. The two traction units 43 are symmetrically arranged on both sides of the gateway box body 10.

[0049] Combination Figure 1 As shown, the traction unit 43 includes a traction rope 431. One end of the traction rope 431 is connected to the twisted wire reel 41, and the other end of the traction rope 431 passes through the wall-mounted plate 20 and is connected to the bearing mechanism 30. It can be understood that, based on the fact that there are two traction units 43 in this embodiment, the twisted wire reel 41 is a twisted wire reel 41 with two twisted wire grooves to avoid the traction ropes 431 of the two traction units 43 from getting tangled together when the twisted wire reel 41 rotates.

[0050] It should be noted that, continue to refer to Figure 1 and Figure 2 In this embodiment, the clamping unit 32 further includes a plug-in block 327, which is disposed on the top surface of the fixing plate 321. The bottom surface of the wall-mounted plate 20 is provided with fixing blocks 21 corresponding to the plug-in blocks 327. Figure 4 As shown, the bottom surface of the fixing block 21 is provided with a plug-in groove for accommodating the plug-in block 327, and the top surface of the fixing block 21 is provided with a first through hole for the traction rope 431 to pass through. The first through hole is connected to the plug-in groove. At this time, the traction rope 431 is connected to the bearing mechanism 30. Specifically, the end of the traction rope 431 away from the twisted coil 41 passes through the wall-mounted plate 20, the first through hole and the plug-in groove in sequence and then connects to the plug-in block 327.

[0051] With this setup, under normal use, the traction rope 431 of each traction unit 43 is in a taut state. When the support plate 31 is below the wall-mounted panel 20 and it is necessary to lift the support plate 31 (e.g.) Figure 1 As shown, the drive unit 42 drives the stranded reel 41 to rotate slowly so that the traction ropes 431 of the two traction units 43 are continuously and synchronously wound around the stranded reel 41. At this time, the support plate 31 can be lifted upward by the traction ropes 431 of the two traction units 43. Since the traction ropes 431 are limited by the first through hole of the fixing block 21, when the plug-in block 327 moves to the position of the fixing block 21, it can be inserted into the plug-in slot of the fixing block 21. Conversely, when it is necessary to lower the support plate 31, the drive unit 42 drives the stranded reel 41 to rotate slowly in the opposite direction to release the traction ropes 431 wound around the stranded reel 41. At this time, the relevant components of the support mechanism 30 and the gateway box body 10 begin to move slowly downward under their own gravity until the support plate 31 and the gateway box body 10 are lowered to a position that is convenient for maintenance and debugging.

[0052] Understandably, in combination Figure 1As shown in this embodiment, the wall-mounted panel 20 is provided with notches corresponding to the traction units 43. The notches penetrate the wall-mounted panel 20. The fixing block 21 is located at the bottom of the wall-mounted panel 20 and aligned with the notches. At the same time, the traction unit 43 also includes a guide wheel 432, which is rotatably disposed in the notch. The end of the traction rope 431 away from the twisted coil 41 passes around the guide wheel 432 and through the notch, and then passes through the first through hole and the insertion slot on the fixing block 21 in sequence, and is connected to the insertion block 327 corresponding to the bearing mechanism 30. By adding the guide wheel 432, the direction of the traction rope 431 can be changed and the friction between the traction rope 431 and the wall-mounted panel 20 can be reduced, thereby improving the service life of the traction rope 431.

[0053] In this embodiment, combined with Figure 4 As shown, the drive unit 42 for driving the twisted wire reel 41 to rotate includes a drive motor 421, a drive shaft 422, a drive gear 423, a transmission shaft 424, and a transmission gear 425. The drive motor 421 is fixedly mounted on the top of the wall-mounted panel 20. The top end of the drive shaft 422 is connected to the drive motor 421 to drive the drive shaft 422 to rotate. The bottom end of the drive shaft 422 vertically penetrates the wall-mounted panel 20 and is connected to the drive gear 423 to drive the drive gear 423 to rotate coaxially. At the same time, the transmission shaft 424 is vertically mounted on the wall-mounted panel 20 and can rotate freely. The twisted wire reel 41 is sleeved on the outer wall of the transmission shaft 424. The bottom end of the transmission shaft 424 penetrates the wall-mounted panel 20 and is connected to the transmission gear 425 to drive the twisted wire reel 41 and the transmission gear 425 to rotate coaxially. The transmission gear 425 meshes with the drive gear 423. With this setup, in actual use, it is only necessary to reasonably control the drive motor 421 to drive the drive shaft 422 to rotate forward or backward. The drive gear 423 and the transmission gear 425 will then drive the stranded reel 41 to rotate forward or backward, thereby enabling the stranded reel 41 to take in and release the traction ropes 431 of the two traction units 43.

[0054] Therefore, the wall-mounted gateway box provided in this embodiment, by adding a traction mechanism 40 and a supporting mechanism 30, not only allows the gateway box to be installed at an appropriate position on the wall, but also enables the direct adjustment of the vertical position of the gateway box as needed, which facilitates the later maintenance and debugging of the gateway box.

[0055] Meanwhile, this embodiment, by setting up a support mechanism 30 composed of components such as a support plate 31, a movable plate 322, and a pressure plate 324, can reliably fix the gateway box and is applicable to fixing gateway boxes of various widths and heights, making it highly practical.

[0056] Example 2

[0057] Based on Embodiment 1, considering that the gateway box body 10 is lifted by a traction mechanism 40 composed of components such as a traction rope 431, the traction rope 431 may be damaged and break during long-term use. Whether the traction rope 431 of one traction unit 43 breaks or the traction ropes 431 of both traction units 43 break simultaneously, it may cause unnecessary losses and accidents. Therefore, this embodiment adds a fall protection component 50 to prevent the gateway box body 10 and the supporting mechanism from falling together after the traction rope 431 of the traction unit 43 breaks.

[0058] In this embodiment, please refer to Figure 6 The plug block 327 has an internal cavity, and the anti-fall component 50 is disposed inside the internal cavity of the plug block 327.

[0059] Specifically, in combination Figure 6 As shown, the fall arrestor assembly 50 includes a support plate 51, a sliding plate 52, a fall arrestor block 53, a first spring 54, and at least two fall arrestor units 55. The support plate 51 is horizontally fixed in the inner cavity of the plug-in block 327. The sliding plate 52 is slidably disposed below the support plate 51, that is, the sliding plate 52 can slide freely in the inner cavity of the plug-in block 327 in the vertical direction. At this time, one end of the first spring 54 is connected to the bottom of the sliding plate 52, and the other end of the first spring 54 is connected to the bottom of the inner cavity of the plug-in block 327. It can be understood that the number of first springs 54 can be set to multiple and distributed in an array to increase the force exerted by the first springs 54 on the sliding plate 52 and improve the stability of the sliding plate 52 during movement.

[0060] Meanwhile, the bottom end of the fall arresting block 53 is connected to the top surface of the sliding plate 52, and the top end of the fall arresting block 53 vertically penetrates the support plate 51 so that the fall arresting block 53 can move synchronously through the sliding plate 52. The top of the plug block 327 is provided with a second through hole that communicates with the inner cavity. The end of the traction rope 431 away from the twisted wire disc 41 passes through the second through hole and is connected to the top end of the fall arresting block 53.

[0061] At least two fall arresting units 55 are sequentially arranged along the circumference of the fall arresting block 53. Preferably, in this embodiment, two fall arresting units 55 are provided, and the two fall arresting units 55 are symmetrically arranged on both sides of the fall arresting block 53. In combination with... Figure 7 As shown, the fall protection unit 55 includes a fall protection post 551, a limiting block 552, and a second spring 553. The outer wall of the plug-in block 327 is provided with fall protection holes corresponding to the fall protection units 55. These fall protection holes horizontally penetrate the plug-in block 327 and are adapted to the fall protection post 551. Figure 6 or Figure 8As shown, the fixing block 21 has an anti-fall groove inside that is adapted to the anti-fall post 551. The anti-fall groove can accommodate the anti-fall post 551 that extends out of the plug block 327 and ultimately support the anti-fall post 551.

[0062] At the same time, continue to refer to Figure 7 The limiting block 552 is fixedly installed on the top surface of the support plate 51. One end of the anti-fall post 551 points towards the anti-fall block 53, and the other end of the anti-fall post 551 extends horizontally through the limiting block 552 into the anti-fall hole. The anti-fall post 551 and the limiting block 552 are slidably connected. The second spring 553 is sleeved on the outer wall of the anti-fall post 551. One end of the second spring 553 is connected to the side of the limiting block 552 away from the anti-fall block 53, and the other end of the second spring 553 is connected to the outer wall of the anti-fall post 551. The end of the anti-fall post 551 facing the anti-fall block 53 has an arc-shaped structure. The outer wall of the anti-fall block 53 near its top is provided with an anti-fall part 53a that corresponds one-to-one with the anti-fall post 551 of the anti-fall unit 55. The anti-fall part 53a is a rectangular block with an arc-shaped structure at the bottom.

[0063] It is understood that in this embodiment, the elastic force of the plurality of first springs 54 is less than the tension applied to the fall arrestor block 53 by the traction rope 431 in the tensioned state, while the elastic force of the second spring 553 is less than the elastic force of the first spring 54.

[0064] With this configuration, under normal use, since the traction rope 431 is connected to the anti-fall block 53 and the traction rope 431 is not broken, the traction rope 431 is always taut, whether the support plate 31 is slowly raised or lowered. At this time, the anti-fall block 53 moves upward due to the tension from the traction rope 431. Since the tension applied to the anti-fall block 53 by the traction rope 431 is greater than the elastic force of the multiple first springs 54, the anti-fall block 53 will drive the sliding plate 52 to move upward until the top surface of the sliding plate 52 contacts the bottom surface of the support plate 51. During this process, the multiple first springs 54 are stretched to store an elastic force. The anti-fall part 53a on the anti-fall block 53 and the end of the anti-fall post 551 with an arc-shaped structure do not contact each other. The second spring 553 of the anti-fall unit 55 is in a naturally extended state. The end of the anti-fall post 551 away from the anti-fall block 53 is hidden in the anti-fall hole on the plug block 327. At this time, since the fall protection posts 551 of both fall protection units 55 are hidden in the fall protection holes corresponding to the plug-in blocks 327, the plug-in blocks 327 can freely insert into or protrude from the plug-in slots of the fixing blocks 21 under the action of the traction rope 431, thus not affecting the normal adjustment of the vertical position of the gateway box body 10 described in the aforementioned embodiment 1. Specifically, when the traction rope 431 is not broken, the structure of each component of the fall protection assembly 50 is as follows: Figure 6 As shown.

[0065] When the gateway box 10 is not normally inspected or debugged, the plug-in block 327 is always inserted into the plug slot of the fixing block 21. During this process, if the traction rope 431 corresponding to the plug-in block 327 breaks, the tension acting on the anti-fall block 53 will disappear instantly. The first spring 54 located below the sliding plate 52 will contract to drive the sliding plate 52 and the anti-fall block 53 to move downwards synchronously. At this time, for a single anti-fall unit 55, when the bottom of the anti-fall part 53a on the anti-fall block 53 contacts the arc-shaped end of the anti-fall post 551, because the elastic force of the first spring 54 is greater than the elastic force of the second spring 553, the anti-fall block 53... The fall arrestor 53a pushes the corresponding fall arrestor 551 to move horizontally. The second spring 553 is stretched to store a spring force. One end of the fall arrestor 551 away from the fall arrestor block 53 extends from the fall arrestor hole on the plug block 327 into the fall arrestor groove of the fixing block 21. As the plug block 327 continues to move downward, when the fall arrestor 551 moves to the bottom of the fall arrestor groove, the fall arrestor 551 will be supported by the bottom of the fall arrestor groove, thereby preventing the plug block 327 from extending out of the plug groove of the fixing block 21, thus realizing the fall arrest function. Specifically, when the traction rope 431 breaks, the structure of each component of the fall arrestor assembly 50 is as follows: Figure 8 As shown.

[0066] In addition, to further improve the stability of the fall arrestor 551 when it extends from the fall arrestor hole on the plug block 327, continue to refer to Figure 7 The top of the fall arresting hole is provided with a locking groove. A third spring 554 and a locking pin 555 are arranged sequentially from top to bottom in the locking groove. One end of the third spring 554 is connected to the top of the locking groove, and the other end of the third spring 554 is connected to the top of the locking pin 555. The bottom end of the locking pin 555 contacts the outer wall of the fall arresting post 551. The outer wall of the fall arresting post 551 is provided with a locking hole that matches the locking pin 555. It can be understood that the locking hole is located on the outer wall of the fall arresting post 551 between the second spring 553 and the locking groove.

[0067] Based on this configuration, under normal use, since the fall arrestor 551 is hidden inside the fall arrestor hole, the bottom of the locking pin 555 contacts the outer wall of the fall arrestor 551. Under the restraint of the fall arrestor 551, the locking pin 555 is hidden in the locking groove, and the third spring 554 is compressed to store a spring force. When the fall arrestor 551 moves horizontally to extend to the outside of the plug-in block 327 under the pushing action of the fall arrestor part 53a of the fall arrestor block 53, once the fall arrestor hole on the fall arrestor 551 moves to the position of the locking groove, the third spring 554 will release the spring force to force the locking pin 555 to extend from the locking groove and insert into the locking hole of the fall arrestor 551, thereby locking the position of the fall arrestor 551 with the locking pin 555 to prevent the fall arrestor 551 from being affected by external force and retracting into the fall arrestor hole of the plug-in block 327.

[0068] On the other hand, once the risk of falling is eliminated, simply reconnecting the traction rope 431 to the fall arrestor block 53 will allow the fall arrestor block 53 to be pulled back by the traction rope 431, thereby resetting the fall arrestor block 53 and the sliding plate 52. At this point, to allow the locked fall arrestor post 551 to retract into the fall arrestor hole of the insertion block 327, continue referring to... Figure 7 A reset port communicating with the locking groove can be opened on the outer wall of the plug block 327, and a reset rod 556 connected to the locking pin 555 is provided in the reset port. When it is necessary to remove the locking pin 555 from the locking hole on the anti-fall post 551, simply push the reset rod 556 upward. Once the locking pin 555 is removed from the anti-fall hole, the second spring 553 will retract to force the anti-fall post 551 to retract into the anti-fall hole. After the anti-fall post 551 retracts into the anti-fall hole, the reset rod 556 can be released to make the bottom of the locking pin 555 re-contact the outer wall of the anti-fall post 551. The operation is simple and convenient.

[0069] Therefore, based on Embodiment 1, this embodiment further adds a fall protection component 50 inside the plug-in block 327. The fall protection component 50 cooperates with the fixing block 21 to restrict the plug-in block 327 within the plug-in groove of the fixing block 21 when the traction rope 431 breaks. This effectively reduces the risk of the gateway box body 10 and the supporting mechanism 30 falling when the traction rope 431 breaks, and improves the safety and reliability of the wall-mounted gateway box.

[0070] Example 3

[0071] Based on Embodiment 1, considering that the drive motor 421 is used as the power source, the position of the gateway box body 10 cannot be adjusted in the event of a power outage. Therefore, this embodiment adds a method for manually adjusting the gateway box body 10, so that the vertical position of the gateway box body 10 can be adjusted during a power outage.

[0072] Specifically, in this embodiment, the driving unit 42 further includes a driving rod 426, which, in conjunction with... Figure 4 As shown, the bottom surface of the drive shaft 422 is provided with a cross-shaped engagement groove, at which point, the engagement... Figure 9 As shown, the top of the drive rod 426 is provided with a locking part 426a that is adapted to the locking groove.

[0073] It is understandable that a telescopic rod can be used as the drive rod 426, and the engaging part 426a is provided at the telescopic end of the telescopic rod, so as to minimize the volume of the drive rod 426 and facilitate the storage of the drive rod 426.

[0074] With this configuration, when there is a power outage and the position of the gateway box body 10 needs to be adjusted, simply insert the engaging part 426a of the drive rod 426 into the engaging groove on the bottom surface of the drive shaft 422, and the drive shaft 422 can be manually driven to rotate by the drive rod 426, thereby adjusting the position of the gateway box body 10. The operation is simple and convenient.

[0075] Therefore, by adding a drive rod 426, this embodiment enables manual adjustment of the vertical position of the gateway box body during power outages, further improving the practicality of the wall-mounted gateway box.

[0076] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
