Description

Technical Field

[0001] The utility model relates to the technical field of strong and weak current boxes, in particular to a spliced ​​strong and weak current cabinet assembly. Background Art

[0002] When renovating a house, high-voltage and low-voltage boxes are often installed in specific areas to arrange circuits in the house, making it convenient for people living in the house to use various electrical appliances through sockets and improve the quality of life. Some places also use a combination of high-voltage and low-voltage cabinets to directly install the high-voltage and low-voltage boxes, avoiding the need to chisel out space when installing them on the wall, which wastes a lot of time.

[0003] Existing, such as Chinese patent publication number CN116191238B discloses an intelligent strong and weak electricity integrated control cabinet, the top of the cabinet is provided with a transformer mechanism, the piston plate is provided with a ventilation component, the cabinet door is used to seal the interior of the cabinet, and the first cylinder drives the piston plate to move downward in the transformer cylinder to increase the internal pressure of the cabinet. Under the action of pressure, the switch piece moves upward in the bottom cabin to block the first connecting pipe. On the contrary, when the first cylinder drives the piston plate to move upward in the transformer cylinder, the air pressure inside and outside the cabinet gradually balances until the internal pressure is less than the external pressure. The switch piece will move downward in the bottom cabin to connect the first connecting pipe and the second connecting pipe, and the gas enters the cabinet after passing through the filter cabin. This reciprocating process can achieve a certain degree of pressurization effect inside the cabinet for a long time, and avoid external corrosive gases entering the cabinet during long-term use, causing corrosion of electrical components.

[0004] Although the above patent can achieve a certain degree of pressurization effect inside the cabinet for a long time, and prevent external corrosive gases from entering the cabinet during long-term use, causing corrosion of electrical components, there are still some shortcomings. For example, the weak current box and the strong current box of the device are of fixed heights, and the weak current box and the strong current box have different height requirements in different scenarios. For example, if the strong current box is installed in the basement, it needs to be 1.5 meters away from the bottom edge. If it is on the first floor and installed in the aisle, it needs to be 1.7 meters away from the ground, which makes the cabinet unsuitable for other scenarios. Therefore, it is necessary to propose a new type of spliced ​​strong and weak current cabinet combination. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the weak current box and the strong current box in the prior art are both at fixed heights, while the weak current box and the strong current box have different height requirements in different scenes.

[0008] Preferably, the back surface of the high-voltage cabinet and the back surface of the low-voltage cabinet are both fixedly connected with ventilation holes, and the inner walls of the two ventilation holes are fixedly installed with electric fans, so that during daily work, the electric fans can be started to blow away the hot air in the cabinet to prevent the electronic components on the low-voltage box and the high-voltage box from overheating.

[0009] Preferably, filter frames are fixedly installed on the back surfaces of the high-voltage cabinet and the low-voltage cabinet, and filter nets are fixedly installed on the inner walls of the two filter frames, so that the vents can be blocked by the filter nets to prevent dust from entering the cabinet through the vents and damaging the electronic components.

[0010] Preferably, observation glasses are fixedly inserted into the inner walls of the two shielding doors, and handles are welded on one side of the outer walls of the two shielding doors, so that when it is necessary to observe the internal situation of the cabinet, it can be directly observed through the observation glass.

[0011] Preferably, a shielding plate is provided between the opposite sides of the high-current cabinet and the low-current cabinet, and the shielding plate is fixedly connected to the bottom of the high-current cabinet and the top of the low-current cabinet by multiple bolt mechanisms, so as to facilitate shielding the interior of the high-current cabinet and the interior of the low-current cabinet, and prevent the signals between the high-current box and the low-current box from interfering with each other.

[0012] Preferably, the outer wall of the shielding plate is provided with a plurality of wiring grooves, and the inner wall of the shielding plate is fixed with an extrusion block by screws, and the outer wall of the extrusion block and the shielding plate are electroplated with a tin layer, which is convenient for wiring the cables that need to be connected between the high-voltage box and the low-voltage box. At the same time, the tin plating can further improve the ability to prevent signal interference.

[0014] 1. In the utility model, by setting threaded rods and knobs, the high-voltage cabinet and the low-voltage cabinet are installed in a space by means of a bolt mechanism, and then it is observed whether the heights of the low-voltage box and the high-voltage box are at the specified heights for the box installation. If not, the heights of the low-voltage box and the high-voltage box can be adjusted by rotating the two knobs using the threaded structure, thereby achieving the problem of being able to adjust the heights of the low-voltage box and the high-voltage box, allowing the low-voltage box and the high-voltage box to be suitable for different scenarios, thereby improving the versatility of the entire cabinet.

[0015] 2. In the utility model, by setting an electric fan, external air can be blown into the interior of the cabinet, which can achieve the effect of cooling the weak current box and the strong current box, and the setting of the filter can also prevent external dust from entering the interior through the vents and affecting the weak current box and the strong current box. At the same time, a shielding plate is also provided to prevent the weak current box and the strong current box from being too close to each other, which is easy to cause signal interference, thereby improving the stability of the cabinet.
