Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for switches, and in particular to a switch mounting bracket structure that is easy to wall-mount. Background Technology

[0002] In the field of electronic communications, switches, as core devices for network data transmission, directly affect the operational efficiency of network systems due to their installation stability and ease of use. With the rapid development of office automation and the Industrial Internet of Things, the application scenarios of switches are becoming increasingly diversified, expanding from traditional server rooms to space-constrained areas such as offices, low-voltage rooms, and industrial sites. Wall-mounted installation has become one of the mainstream installation methods because it saves floor space and facilitates cabling management.

[0003] Chinese patent document CN208011248U discloses a wall mount bracket for a switch, including a shell-shaped mounting plate made of plastic injection molding. The mounting plate has a through hole at the upper right corner and a through hole at the lower left corner. Mounting feet are movably provided at the through holes. The mounting feet can be extended or retracted by moving or rotating. When installed on the wall, the hook can be easily found. It is convenient to use and is very suitable for installing switches or routers on the wall.

[0004] However, the above-mentioned patent documents still have the following defects in practice:

[0005] The core structure of this bracket is a single shell-shaped mounting plate. The positioning structure such as the protruding columns and support feet on the back can only accommodate the installation of one switch, and disassembly is laborious and complicated. The mounting plate has only one square hole in the center for heat dissipation, and the plastic has poor thermal conductivity. The insufficient heat dissipation area can easily lead to heat accumulation and affect the performance of the equipment. Utility Model Content

[0006] The main purpose of this utility model is to provide a switch mounting bracket structure that is easy to wall-mount, which can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A wall-mounted switch mounting bracket structure includes a slide rail. Self-locking mechanisms are installed on the upper and lower sides of the slide rail. Fixtures for securing the slide rail are installed on the left and right sides of the slide rail. Two latches engage with the front of the self-locking mechanisms to cooperate with self-locking. Four positioning blocks are installed between the two latches. A switch housing is mounted in front of the four positioning blocks. A dust-blocking mesh is fitted onto the top and inner walls of the housing. A backplate for securing the switch is installed inside the housing. A door is installed at the front of the housing, and a fan for cooling the switch is installed in the middle of the door.

[0009] The self-locking mechanism includes two fixed baffles, with a support shaft I installed between the two fixed baffles for support. A buckle II for locking the housing is installed on the outer surface of the support shaft I. A limiting block II for limiting the engagement height is installed at the top of the buckle II, located at the top of the two fixed baffles. A pull ring for pulling up the buckle II is installed at the top of the limiting block II. Several limiting blocks I are installed behind the pull ring. Limit blocks III are installed at the rear ends of the two fixed baffles, and several telescopic structures are installed behind the limiting blocks III.

[0010] Preferably, the telescopic structure includes a plurality of support shafts II, each of the outer surfaces of the plurality of support shafts II being fitted with a housing II, each of the plurality of housings II being fitted with a housing I at its top, each of the plurality of housings I being fitted with a guide rod for pushing a limiting block I, each of the plurality of guide rods being fitted with a spring for providing thrust to the guide rod at its bottom end, each of the plurality of springs being located inside the housing I and the bottom end of the spring being fixedly connected to the bottom of the inner side of the housing I, and the top end of each of the plurality of guide rods being fixedly connected to the bottom of the limiting block I.

[0011] Preferably, the rear part of the second buckle is a hollow cylindrical shape, with the middle part horizontal and the front part vertical, and the lower front part of the vertical part of the second buckle is inclined.

[0012] Preferably, the two buckles are arranged horizontally at the front and vertically at the rear, with the upper front part of the vertical portion of the buckle being inclined.

[0013] Preferably, the two buckles are arranged horizontally at the front and vertically at the rear, with the upper front part of the vertical portion of the buckle being inclined.

[0014] Preferably, when the housing is installed on the front side of the slide rail, the rear side of the vertical portion of the second buckle is in contact with the front side of the vertical portion of the first buckle.

[0015] Preferably, the slide rail is provided with slots on both the upper and lower sides of the front end, and the four positioning blocks are in the same position as the slots. When the housing is installed on the front side of the slide rail, the positioning blocks enter the inside of the slots for limiting.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This device uses a self-locking mechanism and buckle one to work together. When the cabinet is installed on the slide rail, buckle one pushes buckle two up. When it reaches the fixed position, buckle two falls down to the horizontal position in front of buckle one and locks the vertical part of buckle one at the rear. When it needs to be removed, pull the pull ring to lift buckle two and unlock the buckle. The switch can be quickly and easily disassembled.

[0018] 2. This device uses a combination of a designed slide rail and a positioning block. The cabinet is slidably connected to the slide rail through the slots of the positioning block, which allows the position of the cabinet to be adjusted so that multiple cabinets can be installed on the slide rail. It has an independent fixing structure for multiple devices and is compatible with the assembly of multiple switches.

[0019] 3. This device achieves good air circulation by using a fan that blows air inward when it rotates, combined with air outlets on the upper side and the left and right sides of the back panel, ensuring smooth airflow inside the enclosure. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] Example 1, as Figure 2 As shown, a switch mounting bracket structure for easy wall mounting includes a slide rail 6. Self-locking mechanisms 4 are installed on the upper and lower sides of the slide rail 6. Fixtures 3 for fixing the slide rail 6 are installed on the left and right sides of the slide rail 6. Two latches 9 are installed on the front side of the self-locking mechanism 4 for self-locking. Four positioning blocks 10 are installed between the two latches 9. A cabinet 1 for placing the switch is installed on the front side of the four positioning blocks 10. A dust-blocking mesh 7 for dust protection is fitted into the top wall of the cabinet 1. A backplate 8 for fixing the switch is installed inside the cabinet 1. A door 2 is installed at the front end of the cabinet 1. A fan 5 for heat dissipation of the switch is installed in the middle of the door 2.

[0033] In this embodiment, the fan 5 consists of three blades, two protective covers, and a drive shaft. The protective cover located on the front side is fixedly installed at the center of the front side of the door 2, and the protective cover located on the rear side is installed at the center of the rear side of the door 2. The drive shaft is installed at the center of the two protective covers and rotates relative to the two protective covers. The blades are fixedly connected to the outer surface of the drive shaft.

[0034] In addition, in this case, the dust filter 7 filters the air entering the switch while ensuring a certain amount of ventilation, so that the heat dissipation system can work more effectively. The dust filter 7 can prevent dust from blocking the heat dissipation channel, ensure that air passes smoothly through the inside of the switch, remove heat, and maintain the switch within the normal operating temperature range.

[0035] Therefore, in this case, the dust filter 7 can be made of common aluminum or stainless steel, such as the SNOWFAN8025 metal dust filter, which is made of pure aluminum, is heat-resistant, rust-proof and durable, has a compact structure and moderate pore size, which can ensure air intake and effectively block dust particles, and will not attract dust like cloth mesh, making it easier to clean.

[0036] Secondly, both fasteners 3 have connection holes at their connection points with the slide rail 6. Before fixing the fasteners 3 to the wall, the two fasteners 3 and the slide rail 6 need to be fixed through the connection holes.

[0037] In addition, in this case, after the cabinet door 2 is closed, it needs to fit snugly against the cabinet body 1 and remain closed at all times. Therefore, a door lock can be installed on the right side of the cabinet body 1 and the cabinet door 2. The recommended door lock is a compression door lock: EMKA109-1101-01. The core advantage of this door lock is that when closed, the lock tongue compresses the door sealing strip, further improving the fit and sealing of the cabinet door 2 and the cabinet body 1. At the same time, it supports dual use, fixing the cabinet door 2 and enhancing dustproof and waterproof performance. The protection level can reach IP65. The lock body structure is sturdy and can withstand a certain amount of external impact, making it suitable for equipment boxes with multiple switches placed together.

[0038] In this embodiment, a control module needs to be installed inside the enclosure 1. This control module can supply power to the switch so that it can work normally. The control module can also supply power to the fan 5 so that the fan 5 can continuously dissipate heat from the switch, keeping the switch at a normal temperature and preventing it from stopping working and malfunctioning due to overheating.

[0039] In this case, the control module can use the existing technology model CloudEngine16804. This module supports multiple power supply methods including DC, AC, and high-voltage DC. The device connects to the external power distribution system through the PEM module and can support two power supplies, A and B. Each PEM module meets the requirements of two inputs to the front end and can convert the input power to achieve stable power supply to the entire switch device. At the same time, the power converted by the PEM module can power the fan 5 through reasonable circuit design and wiring. Its power supply capability is strong and can ensure the continuous operation of the heat dissipation device, effectively dissipating heat for the switch and keeping the switch within the normal operating temperature range, avoiding failure due to overheating. This module design is mature and widely used in switch products. It has high reliability and stability and can ensure the stable operation of the switch and heat dissipation equipment in complex network environments.

[0040] A switch is a network device used for forwarding electro-optical signals. It provides a dedicated electrical signal path for any two network nodes connected to the switch, making it one of the core devices in a Local Area Network (LAN). Its core functions are mainly reflected in the following aspects: First, data forwarding: By analyzing the destination MAC address in the data packet, it accurately forwards data from the source port to the destination port, avoiding collisions in shared-medium networks and improving network bandwidth utilization. Second, address learning: During operation, the switch receives data packets, records the mapping relationship between the source MAC address and the corresponding port, and stores it in a MAC address table for subsequent fast data forwarding. Third, filtering: When the source MAC address and destination MAC address of a data packet belong to the same port, the switch filters out the data packet, avoiding unnecessary forwarding and reducing network traffic. In addition, in complex network topologies, switches also have loop avoidance capabilities, which can detect and eliminate network loops through technologies such as Spanning Tree Protocol (STP), preventing data packets from endlessly looping and causing network congestion.

[0041] Therefore, during implementation, the slide rail 6 is first fixedly connected to the two fixing devices 3 on both sides, and then the two fixing devices 3 are fixed to the wall. When installing the switch, the switch is installed on the front side of the back panel 8, and then the back panel 8 is installed inside the enclosure 1. Then the enclosure 1 is installed on the slide rail 6. The buckle 2 45 is lifted by the buckle 1 9 on the rear side of the enclosure 1. After reaching the position, the buckle 2 45 falls to the horizontal position in front of the buckle 1 9. The buckle 2 45 locks the vertical part of the rear of the buckle 1 9. At this time, the positioning block 10 on the rear side of the enclosure 1 slides in the slot 11. When disassembly is required, the buckle 2 45 is pulled up by the pull ring 43 to open the lock. At this time, the enclosure 1 can be directly pulled out to complete the disassembly.

[0042] Specifically, in order to achieve the locking purpose of the self-locking mechanism 4, please refer to... Figure 6 In this embodiment, the self-locking mechanism 4 includes two fixed baffles 41. A support shaft 46 for support is installed between the two fixed baffles 41. A buckle 45 for locking the housing 1 is installed on the outer surface of the support shaft 46. A limiting block 44 for limiting the engagement height is installed at the top of the buckle 45. The limiting block 44 is located at the top of the two fixed baffles 41. A pull ring 43 for pulling up the buckle 45 is installed at the top of the limiting block 44. Several limiting blocks 42 are installed on the rear side of the pull ring 43. A limiting block 47 is installed at the rear end of the two fixed baffles 41. Several telescopic structures 48 are installed on the rear side of the limiting block 47.

[0043] The telescopic structure 48 includes several second support shafts 485, each of which has a second outer shell 484 mounted on its outer surface. Each of the second outer shells 484 has a first outer shell 482 mounted on its top. Each of the first outer shells 482 has a guide rod 481 mounted on its inner side for pushing the first limiting block 42. Each of the guide rods 481 has a spring 483 mounted on its bottom end for providing thrust to the guide rods 481. Each of the springs 483 is located inside the first outer shell 482 and its bottom end is fixedly connected to the bottom of the inner side of the first outer shell 482. The top end of each of the guide rods 481 is fixedly connected to the bottom of the first limiting block 42.

[0044] The rear part of the second buckle 45 is set in the shape of a hollow cylinder, with the middle part set horizontally and the front part set vertically. The lower front part of the vertical part of the second buckle 45 is set at an angle.

[0045] In this embodiment, in order to ensure that the second buckle 45 can rotate around the first support shaft 46, the rear part of the second buckle 45 is set in a hollow cylindrical shape. In order to ensure that the second buckle 45 can be lifted upward by the push of the first buckle 9, the lower front part of the vertical part of the second buckle 45 is tilted to provide the second buckle 45 with a tilt angle, so that the front part of the second buckle 45 can be lifted upward by the tilting push.

[0046] The two buckles 9 are horizontally positioned at the front and vertically positioned at the rear. The upper front part of the vertical part of buckle 9 is inclined.

[0047] In this embodiment, in order to allow the first buckle 9 to mechanically engage with the vertical part of the second buckle 45, the rear part of the first buckle 9 is set vertically. In order to ensure that the second buckle 45 is not blocked by the vertical part of the first buckle 9 when it is lifted upward, the upper front part of the vertical part of the first buckle 9 is set at an angle.

[0048] In this embodiment, when the housing 1 is installed on the slide rail 6, the first buckle 9 on the rear side of the housing 1 contacts the front of the second buckle 45. The front of the second buckle 45 is subjected to an inclined thrust and rotates upward around the support shaft 46. At this time, the first limiting block 42 rotates backward with the second buckle 45, pushing the guide rod 481 to contract towards the inside of the outer shell 482. The spring 483 generates a compressive force due to the compression of the guide rod 481. After the first buckle 9 moves with the housing 1 to the preset fixed position, the second buckle 45 loses the thrust constraint. The spring 483 releases the compressive force and pushes the guide rod 481 to extend outward to provide thrust for the first limiting block 42. The first limiting block 42 drives the second buckle 45 to rotate in the opposite direction and fall down to reset. The front vertical part of the second buckle 45 falls into the horizontal area in front of the first buckle 9. At the same time, the vertical part of the second buckle 45 is mechanically engaged with the rear vertical part of the first buckle 9, and the housing 1 is stably fixed on the front side of the slide rail 6.

[0049] When disassembling housing 1, pulling the pull ring 43 causes the second buckle 45 to rotate around the support shaft 46 and lift upwards again. At this time, the first limiting block 42 rotates backwards with the second buckle 45, pushing the guide rod 481 to retract inwards towards the outer shell 482. The spring 483 generates compressive force due to the compression of the guide rod 481. At this time, housing 1 is pulled forward, and housing 1 simultaneously causes the first buckle 9 to disengage from the mating area with the second buckle 45. After the first buckle 9 is completely disengaged, the pull ring 43 is released, the second buckle 45 loses its tension constraint, and the spring 483 releases its compressive force to push the guide rod 481 outwards to provide thrust for the first limiting block 42. The first limiting block 42 causes the second buckle 45 to rotate in the opposite direction and fall back to its original position for subsequent reinstallation and use.

[0050] Specifically, in order to achieve the purpose of allowing the housing 1 to move in front of the slide rail 6, refer to... Figure 5 In this embodiment, the upper and lower sides of the front end of the slide rail 6 are provided with slots 11, and the four positioning blocks 10 are in the same position as the slots 11. When the housing 1 is installed on the front side of the slide rail 6, the positioning blocks 10 enter the slots 11 for limiting.

[0051] When the housing 1 is assembled to the front of the slide rail 6, the positioning block 10 on the rear side of the housing 1 is embedded in the inner side of the slot 11 and slides smoothly along the direction of the slide rail 6. After the housing 1 moves to the preset installation position, the positioning block 10 is fastened to the inner side of the slot 11 through the connection hole reserved on the inner side of the positioning block 10 to form a rigid limit, preventing the housing 1 from continuing to slide and completing the fixing.

[0052] When the housing 1 needs to be disassembled from the front of the slide rail 6, first remove the connecting piece between the positioning block 10 and the inner side of the slot 11 to release the fixed relationship between the positioning block 10 and the slot 11. Then pull the housing 1 so that the housing 1 moves the positioning block 10 away from the inner side of the slot 11. When the positioning block 10 is completely away from the guide rail range of the slot 11, the housing 1 can be completely disassembled and removed from the front of the slide rail 6.

[0053] Example 2: Based on Example 1, this example is optimized and improved to improve heat dissipation in housing 1, as follows:

[0054] In this case, the air outlets on the upper side of the box 1 and the left and right sides of the back panel 8 achieve good air circulation, making the air inside the box 1 flow smoothly.

[0055] In addition, the bottom of the enclosure 1 in this case is provided with a wiring hole. When it is necessary to connect to the switch, the wiring can be done through the wiring hole without causing the wires to become tangled or knotted.

[0056] It should be noted that the specific installation method of the backplane 8 and the switch, as well as the connection method and control method of the circuit for controlling the switch and fan 5 power supply in this utility model, are all conventional designs and will not be described in detail in this utility model.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
