Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet equipment, in particular to a power distribution cabinet door with a sealing structure. Background Art

[0002] A power distribution cabinet is a complete set of devices used for centralized installation of switches, instruments, and other equipment. Currently, a power distribution cabinet door consists of a door body with an observation window in the center. The edge of the observation window is secured to the door body and framed. The frame is fixed to the door body. The observation window is used to view the display screens of instruments mounted on the cabinet body. Existing doors are mostly made of sheet metal. When the door is closed, a gap exists between the outer wall of the door and the cabinet body, resulting in poor sealing performance. This allows dust and other particles to easily enter the cabinet body, potentially affecting the normal operation of the power distribution cabinet. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a distribution cabinet door with a sealing structure.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A distribution cabinet door with a sealing structure includes a main door body, an inflatable sealing strip is embedded in the middle of the outer side of the main door body, external sealing strips are fixed to the front and rear ends of the outer wall of the main door body, a fixing cylinder is fixed to the middle of the back side of the main door body through a bracket, connecting pipes are vertically fixed to the rear of the fixing cylinder, a fixing seat is fixed to the middle of the front surface of the main door body, an adjusting bolt is embedded in the middle of the fixing seat, a connecting ring is fixed to the rear end of the adjusting bolt, a connecting disk is nested on the outer side of the connecting ring, and a piston ring is fixed to the back side of the connecting disk.

[0006] Preferably, the inflatable sealing strip is arranged between two outer sealing strips, and the vertical sectional area of ​​the inflatable sealing strip is larger than the vertical sectional area of ​​the outer sealing strips.

[0007] Preferably, a hollow air storage tank is provided inside the fixing cylinder, and the inflation sealing strip is communicated with the inner rear end of the fixing cylinder through two connecting tubes.

[0008] Preferably, the outer wall of the adjusting bolt is connected to the inner wall of the fixing seat via a thread, and the connecting ring at one end of the adjusting bolt rotates horizontally inside the connecting disk.

[0009] Preferably, the piston ring is arranged at the rear end of the air storage tank of the fixed cylinder, and an appropriate amount of gas is injected into the air storage tank.

[0010] Preferably, the outer wall of the piston ring is in close contact with the inner wall of the fixing cylinder, and the piston ring slides back and forth in the fixing cylinder.

[0011] 1. After the main door body is closed and embedded in the cabinet body, the adjusting bolt is rotated in the fixing seat by twisting the adjusting bolt, so that the adjusting bolt pushes the connecting plate and the piston ring to move from back to front in the fixing cylinder through the connecting ring. In the process of the piston ring moving from back to front in the fixing cylinder, the gas in the fixing cylinder is pushed along the connecting pipe into the inflatable sealing strip, so that the inflatable sealing strip expands and becomes close to the cabinet body, further improving the sealing effect between the main door body and the cabinet body, and effectively preventing external dust from entering the cabinet body along the gap between the main door body and the cabinet body.

[0012] 2. After the main door body is closed and embedded in the cabinet body, the inflatable sealing strip is inflated and fits tightly against the cabinet body. At the same time, the outer sealing strips located at the front and rear ends of the outer side of the inflatable sealing strip fit tightly against the cabinet body, achieving multiple sealing between the main door body and the cabinet body, further improving the sealing effect between the main door body and the cabinet body, and effectively preventing external dust from entering the cabinet body along the gap between the main door body and the cabinet body.

[0018] Main door body 1 , inflatable sealing strip 101 , outer sealing strip 102 , fixing tube 2 , connecting tube 201 , fixing seat 3 , adjusting bolt 301 , connecting ring 302 , connecting disk 303 , piston ring 304 . DETAILED DESCRIPTION

[0019] Example 1, with reference to Figure 1-4 A distribution cabinet door with a sealing structure includes a main door body 1, which is characterized in that an inflatable sealing strip 101 is embedded in the middle of the outer side of the main door body 1, and external sealing strips 102 are fixed to the front and rear ends of the outer wall of the main door body 1. A fixing cylinder 2 is fixed to the middle of the back of the main door body 1 through a bracket, and a connecting pipe 201 is vertically fixed to the rear of the fixing cylinder 2. A fixing seat 3 is fixed to the middle of the front surface of the main door body 1, and an adjusting bolt 301 is embedded in the middle of the fixing seat 3. A connecting ring 302 is fixed to the rear end of the adjusting bolt 301, a connecting disk 303 is nested on the outside of the connecting ring 302, and a piston ring 304 is fixed to the back of the connecting disk 303.

[0020] A hollow air storage tank is provided inside the fixing cylinder 2 , and the inflation sealing strip 101 is connected to the rear end of the interior of the fixing cylinder 2 through two connecting tubes 201 .

[0021] The outer wall of the adjusting bolt 301 is connected to the inner wall of the fixing base 3 via a thread, and the connecting ring 302 at one end of the adjusting bolt 301 rotates horizontally inside the connecting disk 303;

[0022] After the main door body 1 is closed and embedded in the cabinet, the adjusting bolt 301 is turned to rotate in the fixing seat 3, so that the adjusting bolt 301 pushes the connecting plate 303 and the piston ring 304 to move from back to front in the fixing cylinder 2 through the connecting ring 302;

[0023] The piston ring 304 is arranged at the rear end of the gas storage tank of the fixed cylinder 2, and a proper amount of gas is injected into the gas storage tank;

[0024] The outer wall of the piston ring 304 is in close contact with the inner wall of the fixed cylinder 2, and the piston ring 304 slides back and forth in the fixed cylinder 2;

[0025] When the piston ring 304 moves from back to front in the fixed cylinder 2, it will push the gas in the fixed cylinder 2 along the connecting pipe 201 into the inflatable sealing strip 101, causing the inflatable sealing strip 101 to expand and become close to the cabinet body, further improving the sealing effect between the main door body 101 and the cabinet body, and effectively preventing external dust from entering the interior of the cabinet body along the gap between the main door body 101 and the cabinet body.

[0026] Example 2: Example 2 differs from Example 1 in that, in this example, the inflatable sealing strip 101 is disposed between the two outer sealing strips 102, and the vertical sectional area of ​​the inflatable sealing strip 101 is larger than the vertical sectional area of ​​the outer sealing strips 102;

[0027] After the main door body 1 is closed and embedded in the cabinet, the inflatable sealing strip 101 is inflated and fits tightly against the cabinet. At the same time, the outer sealing strip 102 located at the front and rear ends of the outer side of the inflatable sealing strip 101 fits tightly against the cabinet, achieving multiple sealing between the main door body 101 and the cabinet, further improving the sealing effect between the main door body 101 and the cabinet, and effectively preventing external dust from entering the interior of the cabinet along the gap between the main door body 101 and the cabinet.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
