[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example 1

[0033] Reference Figures 1-4 A low-voltage communication distribution cabinet with quick connection function includes a low-voltage communication distribution cabinet body 1, an operation port is provided at the front end of the low-voltage communication distribution cabinet body 1, and a cabinet door 5 is installed at the front end of the operation port. A drive assembly 2 is installed on the low-voltage communication distribution cabinet body 1, and a base 4 is fixedly installed on the lower end face of the low-voltage communication distribution cabinet body 1.

[0034] The drive component 2 facilitates the quick installation of electrical components, as well as the laying of cables and the rapid connection of wire ends by staff.

[0035] The drive assembly 2 includes an inverted drive housing 209. Two side mounting brackets 203 are symmetrically installed inside the inverted drive housing 209 and inside the low-voltage interconnection distribution cabinet body 1. Multiple mounting base plates 211 are installed between the two side mounting brackets 203.

[0036] In this embodiment, two side drive ports 6 are symmetrically opened at the left and right ends of the low-voltage interconnection distribution cabinet body 1, which are arranged in the front and back directions. The U-shaped drive housing 209 is fixedly connected to the two side mounting brackets 203 through the two side drive ports 6.

[0037] A motor 213 is fixedly installed on the left rear end face inside the C-shaped drive housing 209. A first lead screw 212, which is arranged in the front-rear direction, is fixedly connected to the front end of the output shaft of the motor 213. A second lead screw 216 is rotatably installed on the right rear end face inside the C-shaped drive housing 209. The second lead screw 216 is arranged parallel to the first lead screw 212 and is mechanically linked. The front end of the second lead screw 216 is rotatably connected to the front end face inside the C-shaped drive housing 209. The first lead screw 212 and the second lead screw 216 are mechanically linked to the two side mounting brackets 203 respectively.

[0038] Both the first lead screw 212 and the second lead screw 216 have transmission wheels fixedly mounted on their rear ends, and the two transmission wheels are connected by a transmission belt 214.

[0039] By starting the motor 213, the motor 213 can drive the first lead screw 212 to rotate. The rotating first lead screw 212 can drive the second lead screw 216 to rotate through two transmission wheels and transmission belt 214.

[0040] Both the first lead screw 212 and the second lead screw 216 are threaded with nut blocks 210. The inner left and right walls of the U-shaped drive housing 209 are symmetrically opened with two strip-shaped openings arranged in the front and back directions. The two nut blocks 210 pass through the strip-shaped openings and the side drive openings 6 in sequence at one end close to each other, and are fixedly connected to the two side mounting brackets 203 at the opposite ends.

[0041] The rotation of the first lead screw 212 and the second lead screw 216 causes the nut block 210 on them to move back and forth, thereby causing the two side mounting brackets 203 to move back and forth, which in turn causes the mounting base plate 211 to move back and forth. When the cabinet door 5 is opened, the mounting base plate 211 can be moved to the front of the operating port, and the motor 213 can be turned off. At this time, the mounting base plate 211 is no longer inside the low-voltage interconnection distribution cabinet body 1.

[0042] Then, the staff can directly press the front of the low-voltage interconnection distribution cabinet body 1 and install the electrical components on the mounting plate 211. After the installation is completed, the cables can be laid immediately until the wire ends are connected. After all is completed, the motor 213 is started in reverse to reverse the first lead screw 212 and the second lead screw 216, and bring the mounting plate 211 back into the low-voltage interconnection distribution cabinet body 1.

[0043] Both side mounting brackets 203 are open at one end and close to each other. A vertically arranged guide rod 204 is fixedly installed inside the side mounting bracket 203. The mounting base plate 211 is symmetrically fixedly installed with C-shaped side blocks 206 at both ends. The rear end of the C-shaped side block 206 is slidably fitted onto the guide rod 204. The front end of the C-shaped side block 206 is detachably fixedly connected to the side mounting bracket 203 through a set screw 208.

[0044] By loosening the set screw 208, the height of the mounting base plate 211 can be adjusted. At this time, the rear end of the U-shaped side block 206 slides up and down on the guide rod 204, thereby adjusting the spacing of the mounting base plate 211 according to the different sizes of the electrical components installed. After adjustment, tighten the set screw 208. Compared with the authorized patent with application number 202323444928.2, this design has a wider adjustment range and is more precise, resulting in better performance.

[0045] Example 2

[0046] Reference Figure 3 A low-voltage communication distribution cabinet with quick connection function, compared with embodiment 1, further includes a positioning component, which is installed on the upper surface of the mounting base plate 211;

[0047] The positioning assembly includes a fixing plate 207. Two fixing plates 207 are provided. The two fixing plates 207 are symmetrically fixedly installed on the upper surface of the mounting base plate 211. A horizontally arranged positioning screw is threaded through the fixing plate 207. The two positioning screws are rotatably installed with a positioning plate 205 at one end close to each other. The lower end surface of the positioning plate 205 slides and fits against the upper end surface of the mounting base plate 211 in the horizontal direction.

[0048] After the electrical components are placed on the mounting base plate 211, the positioning screw can be turned to drive the two positioning plates 205 to move towards each other, thereby positioning the electrical components on the mounting base plate 211.

[0049] Example 3

[0050] Reference Figure 4 A low-voltage interconnection distribution cabinet with quick-connect function, compared with embodiment 1, further includes a mounting back plate 201, which is fixed to the front end face of two side mounting brackets 203.

[0051] Multiple rear air inlets 202 are evenly provided on the mounting back plate 201, and the side end face of the mounting back plate 201 slides and fits against the inner wall of the low-voltage communication distribution cabinet body 1 in the front-to-back direction. Multiple side exhaust holes 3 are provided on both the left and right ends of the low-voltage communication distribution cabinet body 1.

[0052] A fan 215 is fixedly installed on the upper end of the U-shaped drive housing 209 and at the rear side of the low-voltage connection distribution cabinet body 1. The air outlet of the fan 215 passes through the rear end of the low-voltage connection distribution cabinet body 1 and extends into the interior of the low-voltage connection distribution cabinet body 1.

[0053] By activating fan 215, the fan 215 blows air from the rear end of the low-voltage communication distribution cabinet body 1 into the low-voltage communication distribution cabinet body 1. The airflow passes through multiple rear air inlets 202 and blows evenly into the low-voltage communication distribution cabinet body 1. The airflow will drive the moisture inside the low-voltage communication distribution cabinet body 1 and the heat generated by the electrical components during operation to be discharged from the side exhaust ports 3 at both ends of the low-voltage communication distribution cabinet body 1, thereby achieving the functions of moisture prevention and heat dissipation.
