Description

Technical Field

[0001] The utility model relates to the technical field of cable winding, and particularly to a positioning wire feeding mechanism for cables. Background Art

[0002] Cables used in power equipment are generally long. The too-long cables are prone to winding and twisting, thus affecting the use of the cables of power equipment. For example, the cables connecting the charging guns on electric vehicle charging piles; in order to facilitate the use of the cables of power equipment, generally, a winding device is now used to wind or unwind the cables, so as to facilitate the storage and use of the cables.

[0003] Existing cable winding devices usually drive a winding wheel to rotate through a motor or a handle to wind the cable on the winding wheel. However, due to the relatively thick and hard cable, only relying on the rotation of the winding wheel to drive its winding / unwinding, it is easy to cause uneven winding / unwinding of the cable, making the cable unable to be stably wound and arranged, or it is difficult to stably feed the cable during unwinding, resulting in a poor user experience; therefore, the applicant now makes improvements to the cable winding device of power equipment to make it have a stable wire feeding mechanism, so as to improve the user experience when winding and unwinding the cable. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and to provide a positioning wire feeding mechanism for cables. The technical solution adopted by the utility model is as follows:

[0006] In one embodiment, the second runner can be a normal coaxial rotating shaft and runner, and the rotation of the second runner does not change the size of its wire passing hole.

[0007] In another embodiment, those skilled in the art can also set that both the first and second runners have eccentric shafts, and adjust the size of the wire passing hole by the rotation of the two eccentric shafts.

[0008] Preferably, the second runner and the first runner have wire passing grooves, and the adjacent arrangement of the second runner and the first runner makes the wire passing grooves of the two cooperate to form the wire passing hole.

[0009] Preferably, the limit adjustment member enables the first rotating wheel to rotate to a non-friction position in which the diameter of the wire passing hole is larger than the cable diameter and maintained, and enables the first rotating wheel to rotate to an extrusion friction position in which the wire passing hole and the cable diameter are exactly matched and maintained; the limit adjustment member includes a torsion spring and a positioning frame cooperating with the torsion spring; in the non-friction position and the extrusion friction position, the first rotating wheel is prevented from rotating by the torsion spring and the positioning frame.

[0010] Preferably, the second rotating wheel is a coaxial rotating shaft and rotating wheel, the second rotating wheel is transmission-connected to a lower rotating rod, and the lower rotating rod is connected to a power source to drive the second rotating wheel to rotate; when the first rotating wheel is in an extrusion friction position, the second rotating wheel rotates and drives the cable to move by friction force, thereby realizing active retraction and release of the cable.

[0011] Preferably, the present structure also includes a winding drum and a movable frame, and the movable frame is transmission-connected to a reciprocating screw rod, and the reciprocating screw rod rotates to drive the movable frame to move back and forth along it; the second rotating wheel and the first rotating wheel are installed on the movable frame, and the winding drum is located on one side of the movable frame and cooperates with the moving trajectory of the movable frame; the second rotating wheel is sleeved on the lower rotating rod and driven to rotate by the lower rotating rod, and the second rotating wheel can slide relative to the lower rotating rod.

[0012] When paying out the line, the first wheel is in the extrusion and friction position, and the lower rotating rod drives the second wheel to rotate, thereby driving the cable to pay out the line; when winding up the line, the winding drum rotates to drive the cable to be wound up. At this time, the first wheel is adjusted to the non-friction position, and the cable can pass through the wire hole smoothly. The movable frame drives the position of the wheel and the wire hole to move back and forth, so that the second wheel assists in sorting and reciprocating the wire on the winding drum.

[0013] Finally, a circuit control module can be placed in the winding drum, one side of the winding drum is connected to the driving assembly, the other side is provided with an operation panel and a socket, and one end of the cable is connected to an electrical plug.

[0014] The beneficial effects of the utility model are as follows: in the present technical scheme, the cable is limited by the wire hole formed between the second rotating wheel and the first rotating wheel, and the size of the wire hole can be adjusted by the eccentric rotating shaft to adapt to cables of different diameters. The cables can be sorted and positioned before they are retracted or released, which is convenient for winding or releasing the cables. Furthermore, the first rotating wheel is provided with an eccentric rotating shaft and positioned by a limit adjusting member, and the second rotating wheel and the rotating shaft are concentrically arranged. After fixing the size of the wire hole, the second rotating wheel rotates with the cable or drives the cable to be retracted or released when the cable is retracted or released, making the retracting and releasing operations smoother.

[0027] Embodiment 1

[0028] As Figure 1-4 shown, a positioning wire feeding mechanism for a cable includes a first runner 63 and a second runner 62 that are adjacent and cooperate with each other, and a wire passing hole 603 for the cable to pass through is reserved between the second runner 62 and the first runner 63;

[0029] The first runner 63 has an eccentric rotating shaft 64, and a limit adjusting member 65 is cooperatively provided on the eccentric rotating shaft 64. The limit adjusting member 65 limits the rotation of the eccentric rotating shaft 64 to adjust the size of the wire passing hole 603.

[0030] In this embodiment, the second runner 62 is a normal coaxial rotating shaft and runner, and the rotation of the second runner 62 does not change the size of its wire passing hole 603; those skilled in the art can also set both the first and second runners to have eccentric shafts, and adjust the size of the wire passing hole 603 by the rotation of the two eccentric shafts.

[0031] The above structure limits the cable through the wire passing hole formed between the second runner and the first runner, and can adjust the size of the wire passing hole through the eccentric rotating shaft to adapt to cables of different diameters. It can first sort and position the cable during cable winding and unwinding, which is convenient for winding or unwinding the cable. Further, the first runner is provided with an eccentric rotating shaft and is positioned by a limit adjusting member, and the second runner is concentric with the rotating shaft and rotates with the wire during winding and unwinding, making the winding and unwinding operations smoother.

[0032] The second runner 62 and the first runner 63 have wire grooves 66, and the adjacent arrangement of the second runner 62 and the first runner 63 makes the wire grooves 66 of the two cooperate to form the wire passing hole 603.

[0033] The limit adjusting member 65 enables the first runner 63 to rotate to a non-friction position where the diameter of the wire passing hole 603 is greater than the diameter of the cable and maintain it, and enables the first runner 63 to rotate to a position where the wire passing hole 603 exactly matches the diameter of the cable and maintain it; in the non-friction position and the extrusion friction position, the first runner 63 is prevented from rotating relative to the second runner 62 through a torsion spring and a positioning bracket 611, and the positioning bracket 611 is connected to the moving bracket 61.

[0034] The limit adjusting member 65 includes a torsion spring and a positioning bracket 611 that cooperates with the torsion spring.

[0035] As shown in the attached Figure 5 、 6 figure, the second runner 62 is drivingly connected to the lower rotating rod 602, and the lower rotating rod 602 is connected to a power source to drive the second runner 62 to rotate. When the first runner 63 is in the extrusion and friction position, the second runner 62 drives the displacement of the cable by friction when rotating, so as to actively wind and unwind the cable.

[0036] It further includes a cable reel 5 and a moving frame 61, and the moving frame 61 is drivingly connected to a reciprocating lead screw 601, and the reciprocating lead screw 601 rotates to drive the moving frame 61 to reciprocate along it; the second runner 62 and the first runner 63 are installed on the moving frame 61, and the cable reel 5 is located on one side of the moving frame 61 and matches the moving track of the moving frame 61.

[0037] When paying out the cable, the first runner 63 is in the extrusion and friction position, the lower rotating rod drives the second runner 62 to rotate, and then drives the cable to be paid out; when winding the cable, the cable reel 5 rotates to drive the cable to be wound. At this time, the first runner is adjusted to a non-friction position, and the cable can smoothly pass through the wire passing hole. The moving frame 61 drives the positions of the runner and the wire passing hole to reciprocate, so that the second runner assists in sorting and reciprocatingly arranging the cable on the cable reel 5 (to achieve the effect shown in the attached Figure 7 figure).

[0038] The second runner 62 is sleeved on the lower rotating rod 602 and is driven to rotate by the lower rotating rod 602, and the second runner 62 is slidable relative to the lower rotating rod 602.

[0039] As shown in the attached Figure 7 figure, a circuit control module is placed inside the cable reel 5. One side of the cable reel 5 is connected to a driving component, and an operation panel and a socket are arranged on the other side, and one end of the cable is connected to an electricity connection plug 8.
