Examples

Referring to fig. 1-4, the present invention discloses a 7KW ac charging pile, which includes a column 100, a body 200 and a gun line collector 300.

The upright column 100 has a hollow inner cavity to form a space required for folding the gun line 221, thereby avoiding potential safety hazards such as snagging caused by leakage of the gun line 221, and simultaneously improving the tidiness and the attractiveness of the product.

The body 200 includes a control box 210 and a charging gun 220, and the control box 210 is provided with a control panel 211 for facilitating a user to perform a charging operation. The charging gun 220 is inserted in the control box 210. The gun line 221 of the charging gun 220 is connected with the control box 210 after penetrating into the inner cavity of the upright 100 through the wire outlet hole on the upright 100.

The gun wire furler 300 includes a movable pulley weight 310, a corner guide wheel 320 and a pressure wheel 330 disposed in the inner cavity of the mast 100. The movable pulley counterweight 310 is hung on the gun line 221, so that the gun line 221 keeps the trend of falling and gathering, namely, when the gun line 221 is pulled out, the movable pulley configurator ascends along with the pulling of the gun line 221; when the gun line 221 needs to be retracted, the movable pulley weight 310 provides the force required for the retraction of the gun line 221, so that the gun line 221 is retracted by the movable pulley weight 310.

The corner guide wheel 320 is disposed at the wire outlet of the upright 100 to adapt to the curvature requirement of the gun wire 221 and guide the gun wire 221 to be taken out.

The pressing wheel 330 is disposed corresponding to the corner guide wheel 320 and can change its distance from the corner guide wheel 320 to press or release the gun line 221. The pressing wheel 330 rotates along the outgoing direction through the one-way bearing, so that when the pressing wheel presses the gun wire 221, the pulling-out of the gun wire 221 is not hindered, but the retraction of the gun wire 221 is hindered. When the wire needs to be taken up, the space between the pressing wheel 330 and the corner guide wheel 320 is adjusted through the adjuster, so that a gap is formed between the pressing wheel 330 and the gun wire 221, at the moment, the pressing wheel 330 does not generate a blocking effect any more, and the gun wire 221 can retract under the action of the movable pulley counterweight 310.

In a preferred embodiment, the adjuster further comprises a fork 340 and a hold down spring 350. Wherein, the shifting fork 340 is hinged in the inner cavity of the upright 100, the shifting fork end of the shifting fork 340 is connected with the pressing wheel 330, and the pressing end extends out of the upright 100 for pressing. The pressing spring 350 acts on the fork end of the fork 340, so that the pressing wheel 330 always keeps a tendency of closing toward the corner guide wheel 320 to press the gun wire 221, and when the pressing end of the fork 340 is pressed, the fork end presses the spring, a slight gap is generated between the pressing wheel 330 and the gun wire 221, and the gun wire 221 retracts under the gravity of the movable pulley weight 310.

In this embodiment, the length of the pressing end of the shift fork 340 is greater than that of the shift fork end, so as to save labor. The lower end surface of the pressing end is provided with a reinforcing rib 341 to enhance the strength of the pressing end.

In this embodiment, in order to reduce the diameter of the guide wheel required by the guide wheel, the corner guide wheel 320 includes an arc-shaped wheel frame 321 and a plurality of guide wheels 322 rotatably mounted on the arc-shaped wheel frame 321, and an arc shape adapted to the curvature of the gun line 221 is formed through the arc-shaped wheel frame 321.

In an alternative embodiment, the number of the guide wheels 322 is two, and the two guide wheels are respectively rotatably mounted at two ends of the arc-shaped wheel frame 321, and the pressing wheel 330 is disposed at a middle position of the arc-shaped wheel frame 321. With such an arrangement, when the pressing wheel 330 acts on the gun line 221, a slight amount of depression is generated on the gun line 221, so as to further prevent the gun line 221 from retreating, and improve the retreating prevention effect on the gun line 221.

In this embodiment, the pressing wheel 330 and the guide wheel 322 are grooved wheels, and the cross-sectional profile of the grooved wheels is adapted to the gun line 221 to increase the contact area with the gun line 221. In addition, in this embodiment, the pressing wheel 330 is a rubber wheel, and the damping pattern 331 is disposed on the surface of the wheel groove of the pressing wheel 330, so as to further increase the resistance when blocking the gun line 221.

In order to prevent the gun line 221 from deviating from the grooved wheel and to achieve the guiding effect of the gun line 221, the gun line furler 300 further includes two cable guide sleeves 360, and the two cable guide sleeves 360 are respectively disposed at two ends of the corner guide wheel 320. One of the cable guide sleeves 360 is installed in the cable outlet hole, and the other cable guide sleeve 360 is fixed in the column 100. It is easy to understand that the cable guide 360 is made of rubber or plastic material to avoid damaging the gun wire 221.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
