Description

Technical Field

[0001] This utility model belongs to the field of low-voltage engineering technology, and in particular relates to a low-voltage engineering equipment mounting bracket. Background Technology

[0002] Low-voltage electrical equipment refers to electrical equipment used to transmit low-voltage, low-current signals. It typically operates at a voltage below 36V and is mainly used in fields such as communication, security, and automation control. This type of equipment includes, but is not limited to, network switches, telephone systems, surveillance cameras, access control systems, and fire alarm equipment. During the installation of these low-voltage devices, mounting brackets are required for their installation and fixation.

[0003] Chinese patent application CN221150694U discloses a mounting bracket for low-voltage engineering equipment, including a mounting shell and a push groove on its top, and a fixing plate that slides inside the push groove. The main body of the engineering equipment is mounted on the top of the fixing plate, and a dustproof net is installed inside the fixing plate. This utility model uses a positioning mechanism and a through hole to fix the main body of the engineering equipment to the top of the mounting shell, preventing the main body of the engineering equipment from changing position due to external factors during use, facilitating maintenance and repair. When there is too much dust on the surface of the dustproof net, a cleaning mechanism is driven by a push-pull plate to clean the surface of the dustproof net, avoiding affecting the heat dissipation of the main body of the engineering equipment. At the same time, a fan is used to cool the main body of the engineering equipment, effectively improving the heat dissipation effect. This solves the problems of current low-voltage engineering equipment mounting brackets being inconvenient to disassemble and clean, and the inability to clean the dustproof net.

[0004] Although the patent allows for quick installation of the equipment on top of the mounting housing through a positioning mechanism and through-holes, making it convenient to operate and also cooling the engineering equipment and improving heat dissipation, it lacks a quick maintenance function. Workers must disassemble the equipment, remove it from the mounting frame, and then reposition it on top of the frame after maintenance. This reduces maintenance efficiency for heavier equipment, increases the difficulty of operation for workers, and is not conducive to use.

[0005] To address this issue, we provide a mounting bracket for low-voltage electrical engineering equipment. Utility Model Content

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 This utility model is a mounting bracket for low-voltage electrical engineering equipment, including a frame 1 and a quick-assembly assembly 4. A baffle 2 is provided on the front side of the frame 1, and the two sides of the baffle 2 are movably connected to the frame 1 through connecting arms 3. The quick-assembly assembly 4 includes a control shell 41, the front side of the control shell 41 is fixedly connected to the frame 1, a threaded post 42 is movably connected to the bottom of the inner cavity of the control shell 41, a threaded sleeve 43 is threadedly connected to the surface of the threaded post 42, and a pressing arm 44 is fixedly connected to both sides of the threaded sleeve 43.

A mounting frame 45 is fixedly connected to both sides of the bottom of the frame 1, and a support plate 46 is movably connected between the front and rear sides of the inner cavity of the mounting frame 45.

[0028] Specifically: the baffle 2 can block the opening on the front side of the frame 1 to improve the stability of the installation and fixing of the low-voltage engineering equipment; the connecting arm 3 can control the baffle 2 to swing up and down on the front side of the frame 1 to adjust its operating angle, facilitating the installation and disassembly of the low-voltage engineering equipment; the control shell 41 facilitates the installation of the threaded post 42; the threaded post 42 can cooperate with the threaded sleeve 43 to adjust the operating height of the two pressing arms 44; the pressing arm 44 can press one end of the support plate 46, causing the other end to move upward to support the low-voltage engineering equipment inside the frame 1. The device is suspended in mid-air and installed and fixed using the cooperation with the baffle 2. When disassembling, the threaded column 42 is reversed and the threaded sleeve 43 is used to control the pressing arm 44 to move upward, so that it no longer presses one side of the support plate 46. At this time, the support plate 46 slowly unfolds, allowing the low-voltage engineering equipment to move downward until one side of the support plate 46 contacts the ground. Then the baffle 2 is opened, and the staff can pull the low-voltage engineering equipment out of the frame 1, which is convenient for the staff to maintain and repair. The staff does not need to manually lift the low-voltage engineering equipment out of the frame 1.

[0029] A positioning mechanism 5 is provided on the front side of the baffle 2. The positioning mechanism 5 includes a positioning shell 51. The rear side of the positioning shell 51 extends into the inner cavity of the frame 1. A rotating sleeve 52 is provided on the front side of the positioning shell 51. The rear side of the rotating sleeve 52 extends through the positioning shell 51 and is threadedly connected to a screw 53. The rear side of the screw 53 extends through the positioning shell 51 and is fixedly connected to a pressing plate 54. A mounting bracket 55 is movably connected to the surface of the rotating sleeve 52. The bottom of the mounting bracket 55 is fixedly connected to the positioning shell 51. Limiting tubes are fixedly connected to both sides of the bottom of the inner cavity of the positioning shell 51. A limiting plate is provided in the inner cavity of the limiting tube. A limiting rod is fixedly connected to the rear side of the limiting plate. The rear side of the limiting rod extends through the positioning shell 51 and is fixedly connected to the pressing plate 54. A protective device is provided on the rear side of the pressing plate 54. The front of the rotating sleeve 52 is fixedly connected to a knob. The front of the positioning shell 51 has a through hole that mates with the rotating sleeve 52. The two sides of the top rear side of the frame 1 are fixedly connected to slide rods. The surfaces of the slide rods are slidably connected to slide sleeves. The rear side of the slide sleeves is fixedly connected to the extrusion arm 44. The bottom sides of the frame 1 and the bottom sides of the control shell 41 are fixedly connected to fixing plates. The front and rear sides of the bottom of the fixing plates are fixedly opened. The two sides of the front side of the inner cavity of the control shell 41 are fixedly connected to slide rails. The surfaces of the slide rails are slidably connected to sliders. The rear side of the sliders is fixedly connected to the extrusion arm 44. The two sides of the control shell 41 have movable openings that mate with the extrusion arm 44. The two connecting arms 3 are movably connected to the frame 1 through bearings.

[0030] Specifically: the positioning shell 51 facilitates the installation of the rotating sleeve 52, which can rotate smoothly in conjunction with the mounting bracket 55. The screw 53 can cooperate with the rotating sleeve 52 to control the position of the extrusion plate 54. When the low-voltage engineering equipment is lifted by the two support plates 46, the extrusion plate 54 can be controlled to extrude the low-voltage engineering equipment, ensuring its stable installation inside the frame 1. The limiting tube can cooperate with the limiting plate to control the position of the limiting rod. The limiting plate can prevent the limiting rod from dislodging from the inner cavity of the limiting tube. The limiting rod can limit the extrusion plate 54, preventing it from deviating during movement. The anti-slip texture is used to improve the anti-slip effect of the extrusion plate 54. The knob makes it easy for the operator to rotate the rotating sleeve 52. The through hole allows the rotating sleeve 52 to rotate easily. The slide rod and slide sleeve can limit the extrusion arm 44, so that it can be smoothly adjusted up and down. The fixing plate and fixing hole can install and fix the frame 1, improving the stability of the frame 1. The slide rail and slider can limit the threaded sleeve 43 to prevent the threaded sleeve 43 from rotating during movement. The movable opening can facilitate the use of the extrusion arm 44. The bearing makes it easy to connect the arm 3 to control the baffle 2 to adjust the angle of use.

[0031] The working principle of this utility model is as follows: When it is necessary to install low-voltage electrical equipment, the equipment is pushed into the frame 1, and then the threaded column 42 is rotated to make it rotate. The threaded column 42 drives the threaded sleeve 43 to move downward. The threaded sleeve 43 pushes the pressing arm 44 to move downward. The pressing arm 44 presses one end of the support plate 46, causing the other end of the support plate 46 to lift upward, thereby lifting the equipment and suspending it in the frame 1. At the same time, the baffle 2 is closed by the connecting arm 3, blocking the front opening of the frame 1, which plays a role in fixing and protecting the equipment. In order to further stabilize the equipment, the rotating sleeve 52 is rotated to make it rotate on the mounting bracket 55. The rotating sleeve 52 drives the screw 53 to move backward. The screw 53 pushes the extrusion plate 54 to press the equipment backward. The anti-slip texture on the extrusion plate 54 increases friction and prevents the equipment from sliding. When the equipment needs to be repaired, the rotating sleeve 52 is reversed to move the screw 53 forward and drive the extrusion plate 54 to release the pressure on the equipment. Then the threaded column 42 is reversed to move the threaded sleeve 43 upward. The threaded sleeve 43 drives the extrusion arm 44 to move upward so that it no longer presses the pallet 46. The pallet 46 slowly unfolds and descends under the action of gravity until it touches the ground. At this time, the baffle 2 is opened, and the equipment can be pulled out of the frame 1 without manual lifting, thus realizing quick disassembly and assembly and efficient maintenance, reducing the difficulty of operation and improving work efficiency.
