[0001] This utility model relates to the field of plastic production technology, specifically to a mounting bracket for low-voltage electrical engineering equipment. Background Technology

[0002] Low-voltage electrical engineering is a category of electrical applications. Electrical applications can be divided into two categories according to the strength of the power transmission: high-voltage and low-voltage. The electricity used in buildings and building complexes generally refers to AC 220V, low-voltage electricity below 50Hz. Low-voltage electrical engineering mainly provides people with electrical energy and converts electrical energy into other energy sources, such as electricity for air conditioning, lighting, power, etc.

[0003] Existing low-voltage electrical equipment is generally installed on a dedicated mounting rack. The installation method is mostly to stack them one by one and fix them with bolts. Since low-voltage electrical equipment usually has a lot of external wires, stacking the equipment one by one will make the wiring cumbersome, as well as the disassembly and maintenance cumbersome. In addition, stacking will reduce the cooling effect of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mounting bracket for low-voltage engineering equipment, which has the advantages of facilitating cable management and maintenance and cooling, while avoiding the problems of cumbersome wiring and disassembly and poor heat dissipation.

[0005] To facilitate wire harness maintenance and cooling, this utility model provides the following technical solution:

[0006] A mounting bracket for low-voltage electrical engineering equipment includes a housing, the inner wall of which has multiple sets of slots, and a connecting plate is slidably connected to the inner wall of the slots. The bracket also includes:

[0007] The top of the connecting plate is fixedly connected to a mounting base, and the inner wall of the mounting base is rotatably connected to a bidirectional threaded rod. Both sides of the bidirectional threaded rod are threadedly connected to fixing plates. The surface of the connecting plate is provided with a cable tray, and the inner wall of the cable tray is provided with an arc-shaped groove. The inner cavity of the cable tray is located on the side wall of the connecting plate, and a first fixing bolt is threadedly connected to the inner wall of the connecting plate. The bottom end of the first fixing bolt is rotatably connected to a clamping plate.

[0008] According to some embodiments, a connecting pipe is fixedly connected to the side wall of the box, a second fixing bolt is threaded to the top of the connecting pipe, and an arc-shaped plate is rotatably connected to the bottom of the second fixing bolt. Multiple sets of connecting pipes are provided, and the connecting pipes correspond one-to-one with the slots. A limiting post is fixedly connected to the top of the arc-shaped plate, and the limiting post penetrates the connecting pipe.

[0009] According to some embodiments, an air inlet pipe is fixedly connected to the top of the housing, a servo motor is fixedly connected to the top of the air inlet pipe, a rotating shaft is fixedly connected to the output end of the servo motor, a fan blade is fixedly connected to the bottom end of the rotating shaft, a side door is snapped onto the side wall of the housing, and filters are fixedly connected to the inner wall of the air inlet pipe and the bottom of the side wall of the side door.

[0010] According to some embodiments, the top two sides of the box are provided with locking pins, and the locking pins pass through the locking slots and connecting plates. The side wall of the bidirectional threaded rod is threaded with a nut, which is used to fix the bidirectional threaded rod.

[0011] Beneficial effects

[0012] This utility model provides a mounting bracket for low-voltage engineering equipment, which has the following advantages:

[0013] (1) The low-voltage engineering equipment mounting bracket places the equipment on the top of the mounting base and uses the threaded connection between the bidirectional threaded rod and the fixing plate to fix the equipment on the surface of the mounting base. Then, the mounting base on the top of the connecting plate and the equipment are installed in the inner cavity of the box using the slot. The equipment is inserted one by one without affecting each other, which is convenient for subsequent disassembly and maintenance.

[0014] (2) The mounting bracket for the low-voltage electrical equipment allows the external wiring to be inserted through the connecting pipe and then through the cable tray at the bottom of the connecting plate to be connected to the interface of the equipment. The first fixing bolt is used to move the clamping plate to insert the wire into the inner cavity of the arc groove, thus fixing the external wiring in the inner cavity of the box. Similarly, the arc plate is used to fix the wire in the inner cavity of the connecting pipe to further fix the wire and prevent the wire from being placed messily.

[0015] (3) After the installation of the equipment is completed, the side door of the low-voltage engineering equipment mounting bracket can be attached to the side wall of the box. The servo motor drives the fan blade to rotate through the rotating shaft, thereby allowing the external air to enter the inner cavity of the box through the air inlet pipe and then be discharged from the bottom of the side door to cool the equipment. The filter screen can filter the air to prevent dust from entering the inner cavity of the box. Attached Figure Description

The bracket also includes:

[0023] A mounting base 2 is fixedly connected to the top of the connecting plate 102. A bidirectional threaded rod 201 is rotatably connected to the inner wall of the mounting base 2. A fixing plate 202 is threadedly connected to both side walls of the bidirectional threaded rod 201. A cable tray 203 is opened on the surface of the connecting plate 102. An arc groove 204 is opened on the inner wall of the cable tray 203. A first fixing bolt 205 is threadedly connected to the side wall of the connecting plate 102 located in the inner cavity of the cable tray 203. A clamping plate 206 is rotatably connected to the bottom end of the first fixing bolt 205.

[0026] It should be noted that: The device is placed on top of the mounting base 2, and then the bidirectional threaded rod 201 is rotated. Utilizing the threaded connection between the bidirectional threaded rod 201 and the fixing plate 202, the fixing plate 202 slides towards the center of the mounting base 2, thereby fixing the device onto the surface of the mounting base 2. Then, using the sliding connection between the connecting plate 102 and the slot 101, the mounting base 2 on top of the connecting plate 102 and the device are installed inside the housing 1 using the slot 101. Since multiple sets of slots 101 are provided, multiple sets of devices can be installed, and... The external wiring is inserted through the connecting pipe 207 and then through the cable tray 203 at the bottom of the connecting plate 102, and connected to the interface of the equipment. Then, the first fixing bolt 205 is rotated, which drives the clamping plate 206 to move and clamp the wire into the inner cavity of the arc groove 204, thus fixing the external wiring in the inner cavity of the housing 1. The second fixing bolt 208 is rotated, which drives the arc plate 209 to move down, thereby using the arc plate 209 to fix the wire in the inner cavity of the connecting pipe 207, further fixing the wire.

[0033] Operating procedure: Place the device on top of the mounting base 2, then rotate the bidirectional threaded rod 201. Utilizing the threaded connection between the bidirectional threaded rod 201 and the fixing plate 202, the fixing plate 202 slides towards the center of the mounting base 2, thus fixing the device onto the surface of the mounting base 2. Then, using the sliding connection between the connecting plate 102 and the slot 101, the mounting base 2 on top of the connecting plate 102 and the device are installed inside the housing 1 using the slot 101. Since multiple sets of slots 101 are provided, multiple sets of devices can be installed, and multiple sets of devices can be installed. The external wiring is inserted through the connecting pipe 207 and then through the cable tray 203 at the bottom of the connecting plate 102, and connected to the interface of the equipment. Then, the first fixing bolt 205 is rotated, which drives the clamping plate 206 to move and clamp the wire into the inner cavity of the arc groove 204, thus fixing the external wiring in the inner cavity of the housing 1. The second fixing bolt 208 is rotated, which drives the arc plate 209 to move down, thereby using the arc plate 209 to fix the wire in the inner cavity of the connecting pipe 207, further fixing the wire.

[0034] After the equipment is installed, the side door 303 can be snapped onto the side wall of the housing 1 to seal the housing 1.
