DETAILED DESCRIPTION
[0034] The utility model discloses a charging pile, wherein a counterweight is connected to a gun line through a traction rope wound around a pulley block, so that the gravity of the gun line is balanced by the gravity of the counterweight, ensuring that the force exerted by the traction rope on the gun line remains unchanged when the gun line is dragged, avoiding a situation in which a user encounters greater resistance when dragging the gun line for a longer distance, making it easier for the user to drag the gun line to a long distance, and facilitating use.
[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] In this application, the words indicating directions, such as "upper", "lower", "top", "vertical direction", etc., all refer to the directions of the charging pile when it is in normal use.
[0037] See also Figure 1-Figure 5 An embodiment of the utility model provides a charging pile, including a shell 112, a counterweight 109, a pulley block and a traction rope 113; the shell 112 is provided with a wire outlet hole; the counterweight 109 is arranged in the shell 112, and the counterweight 109 can move in a vertical direction; the pulley block includes a movable pulley 108 installed on the counterweight 109 and a fixed pulley 104 installed on the top of the shell 112; the first end of the traction rope 113 is fixed to the top of the shell 112, and the second end successively passes around the movable pulley 108 and the fixed pulley 104 and then extends out of the shell 112 and is connected to the gun line 114 to suspend the gun line 114.
[0038] In the above-mentioned charging pile, the first end of the traction rope 113 is fixed to the top of the shell 112, and the second end of the traction rope 113 first passes around the movable pulley 108 to suspend and pull the counterweight 109 to move up and down in the vertical direction; the second end of the traction rope 113 then passes around the fixed pulley 104, which changes the extension direction and force direction of the traction rope 113, making it convenient for the traction rope 113 to be connected to the gun line 114 after it exits the shell 112, so that the user can use the gun line 114 directly by dragging it.
[0039] When using the above-mentioned charging pile, the user pulls the gun line 114, and the gun line 114 stretches the traction rope 113 and gradually extends out of the shell 112. The traction rope 113 pulls the pulley 108 upward under the steering action of the fixed pulley 104, and the counterweight 109 carried by the movable pulley 108 uses its own weight to balance the tension of the gun line 114 through the traction rope 113; wherein the weight of the counterweight 109 remains unchanged, and the force provided by the counterweight 109 to the gun line 114 through the traction rope 113 also remains constant, and will not increase as the gun line 114 is pulled to a longer distance. Since the movable pulley can reduce the pulling force, compared with the solution of suspending the gun line 114 using a balancer in the prior art, it can save the user effort when dragging the gun line 114 to a long distance, which is convenient for the user to use.
[0040] In addition, the charging pile provided in this embodiment uses the gravity of the counterweight 109 to balance the gravity of the gun line 114. The gun line 114 is subjected to constant force when stretched. When use is over, the gun line 114 can also restore its initial position by itself under the action of the gravity of the counterweight 109, providing a better user experience.
[0041] Furthermore, the pulley block in the charging pile provided in this embodiment applies the movable pulley principle, so that the movement stroke of the traction rope 113 is doubled, and the use range of the gun line 114 is greatly increased.
[0042] The charging pile may be configured to further include a tensioning member 106, which is located between the fixed pulley 104 and the outlet hole, and the tensioning member 106 presses against the traction rope 113. In this embodiment, the charging pile is provided with a tensioning member 106 to keep the traction rope 113 in a tensioned state, so that the traction rope 113 can be reliably wound around the fixed pulley 104, and the traction rope 113 is prevented from being separated from the fixed pulley 104, especially when the gun line is stretched over a long distance, so as to prevent the traction rope 113 from being derailed from the fixed pulley 104 due to a large angle relative to the housing 112.
[0043] In a specific embodiment, the tensioning member 106 may be configured as a tensioning wheel, and the axis of the tensioning wheel is configured to be parallel to the axis of the fixed pulley 104 .

An arc-shaped enclosure 162 may be provided around the threading hole 163, and the arc-shaped enclosure 162 can play a role in guiding the traction rope 113 to slide, reduce the sliding resistance of the traction rope 113, and prevent the traction rope 113 from directly contacting the hole wall of the threading hole 163 to prevent the hole wall of the threading hole 163 from cutting the traction rope 113.
[0045] The arc-shaped enclosure 162 can be configured as an arc plate fixed to the bracket 161, such as Figure 5 As shown, the arc-shaped enclosure 162 includes four parts, forming a ring (specifically, a rectangle) including a threading hole 163, and the part of each part close to the threading hole 163 is a smooth slope, which can prevent the traction rope 113 from being cut when it contacts the hole wall. In addition, the arc-shaped enclosure 162 can also be set as the outer wall of the drum. The drum can be set to multiple, and each drum can be rotatably mounted on the bracket 161 around its own axis. All the drums are arranged in sequence along the circumferential direction, and the outer walls of all the drums surround the above-mentioned threading hole 163.
[0046] The upper edge of the threading hole 163 presses against the traction rope 113, and the upper edge of the threading hole is lower than the lower edge of the outlet hole in the outer shell 112 for leading out the traction rope 113; when the charging pile is in use, the traction rope 113 presses against the upper edge of the threading hole 163 and the lower edge of the outlet hole, ensuring that the traction rope 113 is tensioned under the action of the tensioning member 106.
[0047] Further, the upper edge of the threading hole 163 is also lower than the upper edge of the fixed pulley 104. The traction rope 113 passes around the movable pulley 108 from below and passes around the fixed pulley 104 from above.

[0050] A guide column arranged vertically may also be installed in the housing 112 , and the counterweight 109 is provided with a guide hole for inserting and fitting with the guide column. In the solution provided in this embodiment, the guide column plays a guiding role for the counterweight 109 .
