Description

Technical Field

[0001] This application relates to the field of equipment installation technology, and in particular to a mounting bracket and network device component. Background Technology

[0002] In some scenarios, network devices (such as switches) need to be mounted on mounting rails in indoor information boxes (or low-voltage boxes) using mounting brackets. After installation, the network devices' ports face the side of the information box, making installation and maintenance difficult. Utility Model Content

[0003] This application provides a mounting bracket and a network device assembly. The mounting bracket allows the network device to be rotatably installed inside the information box. The technical solution of the mounting bracket and the network device assembly is described below.

[0004] In a first aspect, this application provides a mounting lug. The mounting lug includes a fixing member, a rotating plate, and a hinge shaft. The fixing member includes a first plate and a second plate connected together, the first plate and the second plate being perpendicular to each other. The first plate has a first mounting hole. The rotating plate is hinged to the second plate via the hinge shaft, the axis of the hinge shaft being perpendicular to the second plate and the rotating plate. The rotating plate has a second mounting hole.

[0005] The technical solution provided in this application allows the first plate of the fixing component to be connected to the mounting rail of the information box via the first mounting hole, and the rotating plate to be connected to the network device via the second mounting hole. In this way, the network device can be installed inside the information box via mounting ears and can also rotate outwards at a certain angle, thus simplifying the installation and maintenance operations inside the information box.

[0006] In one implementation, one of the second plate and the rotating plate has a protruding structure on its surface, while the other has a grooved structure. The protruding structure extends into the grooved structure to restrict the rotation of the rotating plate relative to the second plate. This prevents the network device from rotating arbitrarily within the information box, improving the stability of the network device during installation.

[0007] In one implementation, the groove structure includes a first positioning groove and a second positioning groove. The rotating plate can switch between a first position and a second position by rotation. When the rotating plate is in the first position, the protruding structure extends into the first positioning groove. When the rotating plate is in the second position, the protruding structure extends into the second positioning groove. The first position can also be called the initial position, that is, the position when the network device is not rotated outwards. The second position can also be called the rotation position, or the extreme position of outward rotation. In this way, the network device can be stably positioned in the initial position and the extreme position of outward rotation, preventing the network device from shaking arbitrarily within the information box.

[0008] In one implementation, there are two first positioning grooves, two second positioning grooves, and two protruding structures. The two first positioning grooves, two second positioning grooves, and two protruding structures are symmetrically distributed with respect to the hinge axis. The rotating plate corresponds to one first position and two second positions. The rotating plate can rotate from the first position in one direction to one second position, and can rotate from the first position in another direction to another second position. When the rotating plate is in the first position, the two protruding structures extend into the two first positioning grooves respectively. When the rotating plate is in one second position, one protruding structure extends into one second positioning groove. When the rotating plate is in another second position, the other protruding structure extends into the other second positioning groove.

[0009] The technical solution provided in this application, by setting two first positioning grooves, two second positioning grooves, and two protruding structures symmetrically distributed relative to the hinge axis, allows the structures of the two mounting ears on the two opposing walls of the network device to be identical. That is, the two mounting ears can be interchanged and used interchangeably, eliminating the need for the user to distinguish between them. Furthermore, by setting the two protruding structures to extend into the two first positioning grooves respectively when the rotating plate is in the first position, the stability of the network device in the initial position is improved.

[0010] In one implementation, when the rotating plate is in any second position, the protrusions that do not extend into the second positioning groove are offset from the plate body containing the groove structure. This avoids the protrusions continuously applying pressure to the rotating plate or the second plate body, reducing the possibility of deformation of the rotating plate or the second plate body.

[0011] In one implementation, the rotating plate has a groove structure, and the second plate has a protrusion structure. Since one side of the rotating plate adheres to the wall of the network device, and the other side adheres to the second plate, it is not convenient to install a protrusion structure on the rotating plate. However, one side of the second plate adheres to the rotating plate, and the other side is not adhered to any other surface. Therefore, it is more convenient to install a protrusion structure on the second plate.

[0012] In one implementation, the mounting lug includes a ball screw. The ball screw is fixed to the second plate, and the ball of the ball screw forms a raised structure for extending into a recessed structure. The ball screw includes a housing, a spring, and a ball. The spring is located inside the housing and is used to drive the ball to extend outward. The ball is elastically expandable and contractable relative to the axial direction of the ball screw, thereby facilitating the insertion or removal of the ball into or out of the recessed structure.

[0013] In one implementation, the mounting lug further includes a threaded component, which is fixed to the second plate. The threaded component includes a threaded hole, through which a ball screw passes and is threadedly connected to the threaded component. The threaded component can be a press-fit stud, which can be fixed to the second plate by press-fitting. By incorporating the threaded component, the reliability of the ball screw's fixed connection to the second plate is improved.

[0014] In one implementation, the rotating plate is equipped with a stop rib, which is used to contact the second plate when the rotating plate rotates to the second position. This prevents the network device from rotating outward at an excessive angle.

[0015] In one implementation, the second plate is provided with a stop rib, which is used to contact the rotating plate when the rotating plate rotates to the second position. This prevents the network device from rotating outward at an excessive angle.

[0016] In one implementation, there are two stop ribs, which are symmetrically distributed with respect to the hinge axis. This way, when the rotating plate rotates in both directions, the stop ribs can limit the rotation of the plate.

[0017] In one implementation, the rotating plate bends away from the second plate from the edge near the first plate. This increases the distance between the edge and the mounting rail, ensuring that the rotating plate does not jam against the mounting rail during network device rotation.

[0018] In one implementation, when the rotating plate is close to the edge of the first plate and parallel to the first plate, the edge is flush with or retracted relative to the surface of the first plate facing away from the second plate.

[0019] The technical solution provided in this application, through the above-described configuration, enables the mounting ears to also support wall mounting of network devices. Specifically, when the network device is wall-mounted using the mounting ears, the first plate of the fastener adheres to the wall and is fixedly connected to it. The rotating plate is fixedly connected to the network device. It is understood that if the aforementioned edge protrudes from the surface of the first plate away from the second plate, this edge will abut against the wall, preventing the first plate from adhering to the wall and thus preventing its fixed connection.

[0020] In one implementation, the edge of the rotating plate near the first plate is flush with or protrudes from the surface of the first plate facing the second plate. This way, when the network device is wall-mounted using mounting ears, the edge of the rotating plate is close to or directly abuts the wall. When the network device tends to rotate, the edge contacts the wall, preventing the device from rotating or allowing it to rotate only a small angle, thus reducing the swaying amplitude during wall mounting.

[0021] In one implementation, when the rotating plate is fixedly connected to the network device, the edge of the rotating plate near the first plate body protrudes relative to the back of the network device. The back of the plate has ventilation holes. This creates a gap between the back of the network device and the wall, allowing airflow and thus improving the heat dissipation of the network device.

[0022] In one implementation, the first plate is fixedly connected to a mounting rail in the information box. The rotating plate is fixedly connected to the network device. This allows the network device to be rotatably mounted inside the information box.

[0023] In one implementation, the first plate is used for fixed connection to the wall, and the rotating plate is used for fixed connection to the network device. This achieves wall mounting of the network device.

[0024] Secondly, this application provides a network device assembly. The network device assembly includes a network device and a mounting bracket as described in any of the first aspects. The rotating plate of the mounting bracket is used for fixed connection with the network device.

[0025] The network equipment includes switches (or mini-switches), routers, and optical network units (ONUs).

[0026] In one implementation, the network device component includes two mounting ears, and the rotating plates of the two mounting ears are respectively fixedly connected to two walls opposite to the network device. Attached Figure Description

[0052] Figure 1 A schematic diagram of an information box 100 (or low-voltage box) is shown. Figure 1 As shown, the information box 100 contains a mounting rail 101 for installing network equipment 200. The network equipment 200 may be a switch (or mini-switch), router, or optical network unit (ONU), etc. The accompanying drawings in this application illustrate the network equipment 200 as a switch. Additionally, as... Figure 1 As shown, the information box 100 may also be equipped with a fiber optic cable tray 102. After the optical fiber entering the information box 100 is coiled in the fiber optic cable tray 102, it is then connected to the optical port of the network device 200.

[0053] Figure 2 A schematic diagram of a network device 200 installed inside an information box 100, according to related technologies, is shown. Figure 2 As shown, the network device 200 is fixed to the mounting rail 101 of the information box 100 via mounting ears 300. Each of the network device 200 has a mounting ear 300 on its upper and lower walls, and the two mounting ears 300 are then fixedly connected to two mounting rails 101 respectively. Figure 2 As shown, after the network device 200 is installed, on the one hand, the ports of the network device 200 face the side of the information box 100, making plugging and unplugging operations on the ports of the network device 200 very inconvenient. On the other hand, the network device 200 also obstructs most of the fiber optic cable tray 102, making it possible to operate the fiber optic cable tray 102 only after the network device 200 has been removed, such as performing fiber optic cable coiling or removing unwanted fiber optic cables from the fiber optic cable tray 102, making the operation even more cumbersome. The aforementioned plugging and unplugging operations on the ports and the operations on the fiber optic cable tray 102 can be collectively referred to as installation and maintenance operations.

[0054] In view of the above-mentioned technical problems, embodiments of this application provide a novel mounting lug 300. For example... Figure 3 and Figure 4 As shown, network device 200 is mounted on mounting rail 101 of information box 100 via mounting lugs 300. Furthermore, as... Figure 4As shown, the mounting bracket 300 also supports rotating (or turning) the network device 200 outwards by a certain angle. Thus, when installation and maintenance are required, simply rotate the network device 200 outwards by a certain angle so that its ports face the outside of the information box 100, exposing the fiber optic cable tray 102, without needing to disassemble the network device 200. This simplifies installation and maintenance operations.

[0055] The mounting ear 300 provided in the embodiments of this application will be described by way of example below. Figures 5-9 As shown, the mounting lug 300 includes a fixing member 1, a rotating plate 2, and a hinge shaft 3. The fixing member 1 includes a first plate 11 and a second plate 12 connected together, with the first plate 11 and the second plate 12 perpendicular to each other. The rotating plate 2 is hinged to the second plate 12 via the hinge shaft 3, and the axis I of the hinge shaft 3 is perpendicular to the second plate 12 and the rotating plate 2.

[0056] The technical solutions provided in the embodiments of this application, such as Figure 5 And refer to Figure 3 and Figure 4 As shown, the first plate 11 of the fastener 1 is connected to the mounting rail 101 of the information box 100, and the rotating plate 2 is connected to the wall of the network device 200. In this way, the network device 200 is installed inside the information box 100 by the mounting lugs 300, and the network device 200 can also rotate outward at a certain angle, which is beneficial for installation and maintenance operations inside the information box 100.

[0057] In some examples, such as Figure 9 As shown, the second plate 12 has a first shaft hole 121, and the rotating plate 2 has a second shaft hole 20. The hinge shaft 3 passes through the first shaft hole 121 and the second shaft hole 20. Of course, in some other examples, the hinge shaft 3 may be fixed to the second plate 12 and pass through the second shaft hole 20 on the rotating plate 2. Alternatively, the hinge shaft 3 may be fixed to the rotating plate 2 and pass through the first shaft hole 121 on the second plate 12.

[0058] In some examples, such as Figure 5 As shown, the two opposite walls of the network device 200 are respectively connected to two rotating plates 2 of mounting lugs 300, and the first plates 11 of the two mounting lugs 300 are respectively connected to two mounting guide rails 101. In this way, the rotation of the network device 200 can be made more stable.

[0059] In some examples, such as Figures 6-9 As shown, the first plate 11 is provided with a first mounting hole 111. For example, as... Figure 5 As shown, the first screw 112 passes through the first mounting hole 111 on the first plate 11 and is threadedly connected to the mounting guide rail 101 to achieve a fixed connection between the first plate 11 and the mounting guide rail 101.

[0060] In some examples, such as Figures 6-9 As shown, the rotating plate 2 is provided with a second mounting hole 21. For example, as... Figure 5 As shown, the second screw 211 passes through the second mounting hole 21 and is screwed into the wall of the network device 200 to achieve a fixed connection between the rotating plate 2 and the network device 200.

[0061] In some examples, such as Figures 6-9 As shown, there are two of each of the above-mentioned first mounting hole 111 and the above-mentioned second mounting hole 21.

[0062] Since the rotating plate 2 can rotate relative to the second plate 12, in order to prevent the network device 200 from shaking freely inside the information box 100, in some examples, such as Figure 9 and Figure 10 As shown, one of the second plate 12 and the rotating plate 2 has a raised structure on its surface (such as...). Figure 10 The steel ball 41 in one plate, and the other plate surface has a groove structure (such as steel ball 41 in the other plate). Figure 9 The first positioning groove 22 and the second positioning groove 23 are shown in the figure. The protruding structure is used to extend into the groove structure to limit the rotation of the rotating plate 2 relative to the second plate 12. In the accompanying drawings of the embodiment of this application, the second plate 12 is provided with a protruding structure and the rotating plate 2 is provided with a groove structure as an example.

[0063] The following provides an exemplary description of possible implementations of the aforementioned groove structure and protrusion structure.

[0064] In some examples, such as Figure 9 and Figure 11 As shown in the middle portion, the groove structure includes a first positioning groove 22. When the rotating plate 2 is in the first position, the protruding structure extends into the first positioning groove 22 to stabilize the rotating plate 2 in the first position. This first position can also be referred to as the initial position, that is, the position of the network device 200 before it rotates outward.

[0065] In some examples, such as Figure 6 , Figure 8 , Figure 9 and Figure 11 As shown in the upper and lower parts, the groove structure also includes a second positioning groove 23. The rotating plate 2 can switch between a first position and a second position by rotation. When the rotating plate 2 is in the second position, the protruding structure extends into the second positioning groove 23 to stabilize the rotating plate 2 in the second position. The second position can also be referred to as the rotation position or the extreme position of outward rotation.

[0066] In some examples, such as Figure 8 , Figure 9 and Figure 11As shown, there are two of each of the first positioning groove 22, the second positioning groove 23, and the raised structure (such as the ball screw 4 or steel ball 41 in the figure). The two first positioning grooves 22, the two second positioning grooves 23, and the two raised structures are symmetrically distributed relative to the hinge axis 3. Figure 11 As shown, the rotating plate 2 corresponds to a first position ( Figure 11 The middle part) and two second positions ( Figure 11 The rotating plate 2 (comprising the upper and lower parts) can rotate from a first position in one direction to a second position, and can also rotate from the first position in another direction to another second position. For example... Figure 11 As shown in the middle part, when the rotating plate 2 is in the first position, the two protruding structures extend into the two first positioning grooves 22 respectively. Figure 11 As shown in the upper part, when the rotating plate 2 is in a second position, a protruding structure extends into a second positioning groove 23. Figure 11 As shown in the lower part, when the rotating plate 2 is in another second position, another protruding structure extends into another second positioning groove 23.

[0067] The technical solution provided in this application embodiment, through the above-described arrangement, enables the rotating plate 2 to rotate relative to the second plate 12 in two directions. Thus, as... Figure 5 As shown, the mounting ears 300 installed on the two opposite walls of the network device 200 can be of the same type. That is, the two mounting ears 300 can be interchanged and used interchangeably, and the user does not need to distinguish between them. Furthermore, by setting the rotating plate 2 to the first position, the two protruding structures extend into the two first positioning grooves 22 respectively, improving the stability of the mounting. Figure 3 The stability of network device 200 under the conditions shown.

[0068] It should be noted that the two first positioning grooves 22 are symmetrically distributed with respect to the hinge axis 3, meaning that in Figure 11 In the top view, let the line connecting the two first positioning grooves 22 be the first connecting line, and let the reference line passing through the axis of the hinge shaft 3 and perpendicular to the first connecting line be the first reference line. Then, the two first positioning grooves 22 are mirror-symmetrical about the first reference line. The two second positioning grooves 23 are symmetrically distributed with respect to the hinge shaft 3, meaning that in... Figure 11 In the top view, let the line connecting the two second positioning grooves 23 be the second connecting line, and let the reference line passing through the axis of the hinge shaft 3 and perpendicular to the second connecting line be the second reference line. Then, the two second positioning grooves 23 are mirror-symmetrical about the second reference line. The symmetrical distribution of the two protruding structures relative to the hinge shaft 3 means that, in... Figure 11In the top view, let the line connecting the two protruding structures be the third line, and let the reference line passing through the axis of hinge axis 3 and perpendicular to the third line be the third reference line. Then the two protruding structures are mirror-symmetric about the third reference line.

[0069] In some examples, such as Figure 12 As shown, when the rotating plate 2 is in any second position, the protruding structure that does not extend into the second positioning groove 23 is misaligned with the plate body (rotating plate 2 in the figure) where the groove structure is located. In this way, the protruding structure can be prevented from constantly applying pressure to the rotating plate 2, thus preventing deformation of the rotating plate 2 surface.

[0070] In some examples, such as Figure 12 As shown, the edge of the rotating plate 2 opposite to the protruding structure is bent away from the second plate 12 to avoid the rotating plate 2 abutting against the protruding structure.

[0071] In some examples, such as Figure 9 and Figure 10 As shown, the rotating plate 2 has a groove structure, and the second plate 12 has a protruding structure. Since one side of the rotating plate 2 is attached to the wall of the network device 200, and the other side is attached to the second plate 12, it is not convenient to install a protruding structure on the rotating plate 2; for example, it is not convenient to install ball screws 4. On the other hand, one side of the second plate 12 is attached to the rotating plate 2, and the other side is not attached to any other surface. Therefore, it is convenient to install a protruding structure on the second plate 12.

[0072] In some examples, such as Figure 6 , Figure 8 and Figure 9 As shown, the mounting lug 300 includes a ball screw 4, which is fixed to the second plate 12. The ball screw 4 has a protruding ball 41 that extends into the recessed structure. The ball screw 4 can also be called a positioning ball screw or a spring plunger. The ball screw 4 includes a housing, a spring, and a ball 41. The spring is located inside the housing and drives the ball 41 to extend outward. Therefore, the ball 41 can elastically expand and contract relative to the axial direction of the ball screw 4, thus facilitating the insertion or removal of the ball 41 into or out of the recessed structure.

[0073] In some examples, such as Figure 6 , Figure 8 and Figure 9 As shown, the mounting lug 300 also includes a threaded component 5, which is fixed to the second plate 12. The threaded component 5 includes a threaded hole, through which a ball screw 4 passes and is threadedly connected to the threaded component 5. The threaded component 5 can be a press-fit stud, which can be fixed to the second plate 12 by press-fitting. By providing the threaded component 5, the reliability of the ball screw 4's fixed connection to the second plate 12 is improved.

[0074] In some examples, such as Figures 6-11As shown, the rotating plate 2 is provided with a stop rib 24. The stop rib 24 is used to contact the second plate body 12 when the rotating plate 2 rotates to the second position. In this way, the network device 200 can be prevented from rotating outward at an excessive angle. For example, Figures 6-11 As shown, the second plate 12 is provided with a stop groove 122, and the stop rib 24 is used to extend into the stop groove 122. It can be understood that the limiting resistance of the above-mentioned groove structure and protrusion structure is small, while the limiting resistance of the stop rib 24 is large.

[0075] Of course, in other examples, the second plate 12 may be provided with a stop rib 24, which is used to contact the rotating plate 2 when the rotating plate 2 is rotated to the second position.

[0076] In some examples, such as Figure 11 As shown, there are two stop ribs 24, which are symmetrically distributed with respect to the hinge axis 3. This ensures that when the rotating plate 2 rotates in both directions, the stop ribs 24 can limit the rotation of the rotating plate 2. The symmetrical distribution of the two stop ribs with respect to the hinge axis 3 means that, in… Figure 11 In the top view, let the line connecting the two stop ribs 24 be the fourth line, and let the reference line passing through the axis of the hinge shaft 3 and perpendicular to the fourth line be the fourth reference line. Then the two stop ribs 24 are mirror symmetrical about the fourth reference line.

[0077] During the rotation of the rotating plate 2, to avoid interference between the rotating plate 2 and the mounting guide rail 101 in the information box 100, in some examples, such as... Figure 13 and Figure 14 As shown, the rotating plate 2 is bent away from the second plate 12 at the edge (i.e., the bent edge 25) near the first plate 11. This increases the distance between the bent edge 25 and the mounting rail 101, ensuring that the rotating plate 2 will not get stuck with the mounting rail 101 during the rotation of the network device 200.

[0078] Besides the scenario where network device 200 is installed in information box 100 via mounting ear 300, in other scenarios, such as Figure 15 and Figure 16 As shown, network device 200 may also be wall-mounted. To enable mounting ears 300 to also support wall-mounting of network device 200, in some examples, such as... Figure 13 , Figure 16 and Figure 17 As shown, when the rotating plate 2 is in the first position, the rotating plate 2 is close to the edge of the first plate 11 (i.e., Figure 16 and Figure 17The bent edge 25 in the fastener 1 is flush with or retracted relative to the surface of the first plate 11 facing away from the second plate 12 (i.e., the first plate surface 113). In this way, the first plate 11 of the fastener 1 can conform to the wall 400 and be fixedly connected to the wall 400. It is understood that if the bent edge 25 protrudes relative to the surface of the first plate 11 facing away from the second plate 12 (i.e., the first plate surface 113), the bent edge 25 will abut against the wall 400, preventing the first plate 11 from conforming to the wall 400 and thus preventing its fixed connection.

[0079] In some examples, to improve the reliability of wall-mounted network devices, such as... Figure 13 , Figure 16 and Figure 17 As shown, the edge of the rotating plate 2 near the first plate 11 is flush with or protrudes from the surface of the first plate 11 facing the second plate 12 (i.e., the second plate surface 114). Thus, when the network device 200 is wall-mounted, the bent edge 25 of the rotating plate 2 is close to or directly abuts against the wall 400. This means that when the network device 200 tends to rotate, the bent edge 25 will contact the wall 400, preventing the network device 200 from rotating, or allowing it to rotate only a small angle. This reduces the swaying amplitude of the network device 200 during wall-mounting.

[0080] In some examples, such as Figure 16 and Figure 17 As shown, when the rotating plate 2 is fixedly connected to the network device 200, the edge of the rotating plate 2 near the first plate 11 (i.e., the bent edge 25) protrudes relative to the back surface 201 of the network device 200. Wherein, as Figure 18 As shown, the back 201 of the network device 200 may be provided with heat dissipation holes 202. In this way, there is a gap between the back 201 of the network device 200 and the wall 400 for airflow, thereby improving the heat dissipation effect of the network device 200.

[0081] In some examples, such as Figure 8 As shown, the edge of the second plate 12 away from the first plate 11 includes a protrusion 123 and two recesses 124, with the protrusion 123 located between the two recesses 124. The protrusion 123 points towards the position between the two second mounting holes 21, and the two recesses 124 are respectively used to avoid the two second mounting holes 21 or the two second screws 211, so as to avoid interference between the second screws 211 and the second plate 12. Specifically, when the rotating plate 2 is in the second position, the recesses 124 are offset from the second mounting holes 21 or the second screws 211.

[0082] This application also provides a network device component. For example... Figure 5As shown, the network device component includes a network device 200 and the aforementioned mounting bracket 300, with the rotating plate 2 of the mounting bracket 300 fixedly connected to the network device 200.

[0083] In some examples, such as Figure 5 As shown, the network device assembly includes two mounting ears 300, and the rotating plates 2 of the two mounting ears 300 are respectively fixedly connected to two walls opposite to the network device 200.

[0084] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
