[0005] In a preferred solution, a threaded joint with internal threads is fixedly installed on the end of the plug with a smaller diameter, and a U-shaped wire tube is installed on the threaded joint through threaded cooperation.
[0006] In a preferred embodiment, a slag discharge port is provided at the bottom of the arc-shaped corner area of the U-shaped wire tube.
[0007] In a preferred solution, an inflatable soft cavity is installed on the outer wall of the middle part of the plug, and the inflatable soft cavity is in contact with the edge of the wire hole.
[0008] In a preferred solution, a hexagonal joint is provided on one end of the screw rod away from the fixing seat.
[0009] The utility model provides a distribution cabinet wire hole blocking structure, which has the following beneficial effects by adopting the above structure:
[0010] (1) The plug with a variable diameter structure relies on the screw rod to achieve an interference fit between it and the wire hole, which can effectively improve the sealing performance and prevent water vapor from entering;
[0011] (2) The U-shaped wire tube can ensure smooth cable installation while recovering any water vapor that may enter and discharging it through the slag discharge port, further ensuring the dryness inside the distribution cabinet. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0013] Figure 1 It is a schematic diagram of the overall structure of the utility model.
[0014] In the figure: power distribution cabinet 1, wire hole 101, plug 2, through hole 201, fixing seat 3, screw rod 4, hexagonal joint 401, threaded hole 5, air-filled soft cavity 6, threaded joint 7, U-shaped wire tube 8, slag discharge port 801. DETAILED DESCRIPTION
[0015] like Figure 1 A wire hole sealing structure for a distribution cabinet is disclosed, comprising a distribution cabinet body 1, a wire hole 101 being provided at the bottom of the distribution cabinet body 1, a plug 2 being inserted at the wire hole 101 in the distribution cabinet body 1, a through hole 201 being provided in the middle of the plug 2 for the cable to pass through, the plug 2 being a variable diameter structure, an end with a smaller diameter being inserted into the wire hole 101, an edge being provided at an end with a larger diameter, a threaded hole 5 being provided on the edge, a screw rod 4 being passed through the threaded hole 5, and one end of the screw rod 4 being movably connected to a fixing seat 3 provided around the wire hole 101.
[0016] In a preferred solution, a threaded joint 7 with internal threads is fixedly mounted on the end of the plug 2 with a smaller diameter, and a U-shaped wire tube 8 is mounted on the threaded joint 7 through threaded matching.
[0017] In a preferred embodiment, a slag discharge port 801 is provided at the bottom of the arc-shaped corner area of the U-shaped wire tube 8 .
[0018] In a preferred solution, an inflatable soft cavity 6 is installed on the outer wall of the middle part of the plug 2, and the inflatable soft cavity 6 is in contact with the edge of the wire hole 101.
[0019] In a preferred solution, a hexagonal joint 401 is provided on one end of the screw rod 4 away from the fixing seat 3 .
[0020] The present invention discloses a plugging structure for a wire hole in a power distribution cabinet. When plugging a wire hole 101:
[0021] like Figure 1 , install the plug 2 in the wire hole 101, make the upper end of the screw rod 4 pass through the threaded hole 5, use the hexagonal wrench to cooperate with the hexagonal joint 401 at the upper end of the screw rod 4, and synchronously drive the multiple screw rods 4 to rotate. During this process, the plug 2 gradually moves down and pushes into the wire hole 101. On the plug 2 installed in place, the inflatable soft cavity 6 is in contact with the wire hole 101. At this time, the inflatable soft cavity 6 is inflated to form two upper and lower inflatable cavities, thereby ensuring the installation stability of the plug 2 at the wire hole 101, and then remove the hexagonal wrench.
[0022] After completing the above installation work, install the U-shaped wire tube 8 on the threaded joint 7 at the bottom of the plug 2, pass the cable through the U-shaped wire tube 8 in advance, and the cable extending from the upper end of the U-shaped wire tube 8 passes through the through hole 201 and directly extends into the distribution cabinet.
