Definitions

  • the present invention relates to a reinforced electric wire box, and more particularly to a reinforced electric wire box that can be firmly connected to a wall.
  • BACKGROUND OF THE INVENTION At present, wire boxes used in interior decoration and homes are mostly fixed in the wall by friction between the wire box itself and the wall, or the wire box and the wall are made of adhesive or cement. Bonding, the fixing between the wire box and the wall is not very reliable, and the wire box is easily deformed and broken by the wall pressing, especially when the wire box is externally connected to the socket, and the plug is broken after being inserted and removed multiple times. The electric wire box is prone to the overall fall off, and the electric shock accident caused by it is also common.
  • the reinforced electric wire box of the present invention includes a wire box, a connecting device with the upper cover, and a connecting device with the wall, wherein the connecting device with the upper cover is mounted on the upper middle portion of the casing, and the connecting device with the wall is An expansion sleeve on the corner or side of the wire box.
  • the reinforcing wire box of the present invention and the connecting device of the upper cover are two protruding bodies with threaded holes.
  • the expansion sleeve is on the four or four sides (which may be one to four, preferably two or four) of the electric box, and the expansion sleeve is integrally connected with the electric box, and the expansion strip on the outer end surface of the expansion sleeve has a strip Flange.
  • the expansion sleeve has two front thin and thick thick trapezoidal expansion strips, and the movable plug of the expansion sleeve is embedded with a nut and connected with a screw.
  • the reinforced electric wire box of the invention is convenient to install, and is installed. The connection is firmly JL.
  • the structure of the present invention is extremely simple, and can be produced by adding a small amount of input to the existing electric wire box production, and the cost is low, and can be recycled and reused after use, thereby improving resource utilization and having a promising market prospect.
  • Figure 1 is a schematic view of the structure of the present invention
  • Figure 2 is a partial cross-sectional view of the expansion sleeve of the present invention.
  • symbol 1 represents the wire box
  • symbol 2 represents the connection device with the wall
  • symbol 3 represents the screw
  • symbol 4 represents the nut
  • symbol 5 represents the expansion bar
  • symbol 6 represents the expansion sleeve
  • symbol 7 represents the upper cover Connecting means
  • symbol 8 represents a strip flange.
  • the reinforced electric wire box of the present invention comprises a wire box 1, a connecting device 7 with the upper cover, and a connecting device 2 to the wall, wherein the connecting device 7 with the upper cover is mounted on the casing 1.
  • the connecting device 1 to the wall is an expansion sleeve 6 at the corner (or side) of the wire box.
  • the reinforcing wire box of the present invention and the connecting device 7 of the upper cover are two protruding bodies with threaded holes, and the expansion sleeve 6 is at the four corners or four sides of the electric wire box 1 (may be available at four corners, or There are two corners, the other two are ordinary or not, and can also be on the four sides.
  • the expansion sleeve 6 is connected to the electric wire box 1 as a whole, and the expansion strip 5 on the outer end surface of the expansion sleeve 6 has a strip.
  • the expansion sleeve 6 When the expansion sleeve 6 is mounted on the corner, there are two outwardly thin front and rear thick trapezoidal expansion strips 5, and when installed on the side, there is an outwardly thin front and rear thick trapezoidal expansion strip 5,
  • the movable plug inner nut 7 of the expansion sleeve 6 is connected to the screw 3.
  • the screw When the invention is used, the screw is first retracted to the tail end of the expansion sleeve, the invention is placed into the wall body, and the screw is turned to move the expansion strip along the inclined surface in the expansion sleeve, and the expansion sleeve is pushed and expanded outwardly.
  • the strip-shaped flange distributed on the outer surface of the expansion strip increases the friction force, so that the entire electric wire box is firmly fixed in the wall body.
  • the invention can also be recycled and reused after use. When the screw is retracted, the expansion sleeve moves forward, the pressing force of the expansion strip is reduced, the friction is reduced, and the wire box can be easily recovered.
