Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the device comprises a box body 1, a box door 2, a control switch 3, a rain blocking strip 4, a rain blocking cover 5, a windscreen wiper 6, a buffer sponge 7 and a transparent observation window 8.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model discloses a distribution box, including box, chamber door and wiper, set up instrument and control switch in the box. The four corners of the box body are provided with bolt holes for fixing the box body in a notch of a wall. The box door is movably connected in the opening in the front of the box body through a hinge, the hinge is connected on the left side of the box door and the left side of the opening of the box body, and the door lock is arranged on the right side of the box door. The upper part of the box door is provided with a transparent observation window corresponding to the instrument, the lower part of the box door is provided with a rectangular operation opening corresponding to each control switch, and the operation opening is sleeved outside the control switches, so that the water inflow of the box body can be reduced. A rain-proof cover is movably connected above the operation opening through a hinge. The rain-proof cover can be turned over up and down. The inner wall of the lower end of the rain cover is vertically connected with a positioning column, the box door below the operation opening is provided with a corresponding positioning hole, and when the operation opening is turned over under the rain cover, the positioning column is just sleeved in the positioning hole. The wiper blade includes a driving motor, a link and a wiper strip. The wiper strip is made of rubber, sponge or cotton cloth and other wiper materials. The driving motor is fixedly connected to the back face of the box door below the transparent observation window, one end of the connecting rod is connected with the rotating shaft of the driving motor, the other end of the connecting rod is connected with the wiper strip, the wiper strip abuts against the inner wall of the transparent observation window, and the driving motor is electrically connected with one of the control switches. The connecting rod can be a multi-connecting rod or a single connecting rod; when the multi-connecting rod is adopted, the continuous rotation of the motor is converted into the back-and-forth swing through the multi-connecting rod, similar to a windscreen wiper of an automobile; when the single connecting rod is adopted, the wiper can directly swing back and forth through the driving motor with the internal controller. After the drive motor is electrified through the corresponding control switch, the drive motor drives the wiper strip to swing back and forth through the connecting rod, so that rainwater and water mist on the inner wall of the transparent observation window are scraped, the instrument in the box can be observed through the transparent observation window more clearly, the box door does not need to be opened for cleaning, and the use is more convenient.

As shown in fig. 1, the driving motor is a bidirectional speed reducing motor, and the control switch electrically connected to the driving motor is a double-pole double-throw switch. The double-pole double-throw switch is used for realizing positive connection and reverse connection of a circuit of the driving motor, further realizing positive rotation and reverse rotation of the driving motor, and the speed reducing motor is slower in rotating speed, easier to control and larger in rotating force. When the double-pole double-throw switch is shifted to the upper end, the speed reducing motor rotates forwards, and the wiper strip swings rightwards; when the double-pole double-throw switch is shifted to the lower end, the speed reducing motor rotates reversely, and the wiper strip swings leftwards; when the double-pole double-throw switch is shifted to the middle part, the speed reducing motor is powered off, and the wiper strip stops swinging.

As shown in fig. 1, the middle of the wiper strip is movably connected with the connecting rod through a round shaft, so that the wiper strip can rotate around the round shaft. The round shaft is sleeved with a cylindrical spring, and two ends of the cylindrical spring are fixedly connected with the wiper strip and the connecting rod respectively, so that the cylindrical spring limits the rotation amplitude of the wiper strip, and the wiper strip rotates around the round shaft to rotate elastically. The wiper strip and the connecting rod are connected through combination of the round shaft and the cylindrical spring, and can be properly rotated according to friction force between the wiper strip and the transparent observation window to adapt to the shape of the transparent observation window, so that collision damage of the wiper strip can be reduced, and a cleaning effect can be improved.

As shown in figure 1, two sides of the inner wall of the transparent observation window are respectively provided with a buffer sponge. The buffering sponge can prevent and buffer the excessive swing of windscreen wiper strip, reduces the damage of windscreen wiper strip, can in time absorb rainwater and water smoke that the windscreen wiper strip struck off simultaneously, improves the clearance effect of wiper, improves the definition of transparent observation window.

As shown in fig. 1, the door further comprises a weather strip, and the weather strip is fixed on the front surface of the door and the back surface of the door between the operation opening and the hinge in a protruding manner. The rain strip on the front side of the box door can stop water flow falling from the front side of the box door from flowing into the control switch, and the rain strip on the back side of the box door can stop water flow falling from the back side of the box door from flowing into the control switch, so that the open circuit and the electric leakage of the control switch are reduced. The rain blocking strips are downwards inclined from the middle to the two ends respectively, rainwater can be guided to flow down from the middle to the two ends, and the rainwater is reduced to flow into the control switch. The length of the rain-shielding strip is larger than that of the operation opening and smaller than that of the rain-shielding cover, so that rainwater at the tail end of the rain-shielding strip is prevented from flowing into the control switch, the rain-shielding strip covering the outside of the box door when the rain-shielding cover is folded is convenient, and the aging of the rain-shielding strip is reduced. The water flowing groove is formed in the upper surface of the rain blocking strip along the length direction, so that water on the rain blocking strip can be reduced from overflowing into an operation opening of the control switch, electric leakage and electric shock accidents are reduced, and the safety is higher.
