[0036] The embodiment of the present utility model provides a wire tube retractor and a charging pile system. The wire tube retractor can reel in the charging pile cable, pull out the amount needed, lock the cable length, and retract the cable when not in use. The cable can be fixed on the top or side of the parking space for use, which is easy to use and reduces the safety hazards when using the charging pile cable.

[0037] The following combination Figure 1-Figure 7 The technical solution provided by the utility model is described in more detail.

[0038] Embodiment 1:

[0039] like Figure 1-Figure 7As shown, the wire tube reel provided by the utility model includes a housing 1, a wire reel 2, an elastic member and a claw assembly, wherein: the wire reel 2 is rotatably connected to the housing 1 for winding or releasing the wire tube, and the housing 1 is provided with a wire outlet 11 for the wire tube to extend out; one end of the elastic member is fixed to the rotating shaft 6 of the wire reel 2, and the other end is fixedly connected to the wire reel 2. When the wire tube is pulled, the wire reel 2 rotates and continuously releases the wire tube; the claw assembly and the wire reel 2 have a positioning state and a disengaged state. When in the disengaged state, the claw assembly positions the wire reel 2. When in the disengaged state and the external force pulling the wire tube disappears, the elastic member can drive the wire reel 2 to reset and reel the wire tube.

[0040] The wire pipes may be air compressor pipes, electric wires, water pipes, charging pile cables, etc. This embodiment is described by taking the wire pipes as cables as an example.

[0041] Specifically, this embodiment provides a specific implementation of a cable reel 2:

[0042] See also Figure 2-Figure 4 As shown, the cable reel 2 includes a reel body 21 and a limiting baffle 22, wherein: the reel body 21 is used for winding the wire tube, and a receiving cavity 211 is provided in the reel body 21. One end of the elastic member is fixed to the rotating shaft 6 passing through the reel body 21, and the other end is fixed to the inner wall of the reel body 21. The limiting baffle 22 is fixed to the opposite sides of the reel body 21 and closes the receiving cavity 211. Figure 4 As shown, the elastic member of this embodiment includes a coil spring 4.

[0043] See also Figure 2 As shown, the winding drum 2 is rotatably connected to the housing 1 through the rotating shaft 6, one end of the coil spring 4 is fixed to the rotating shaft 6, and the outer end is a free end fixed to the inner wall of the winding drum body 21, see Figure 3 and Figure 4 As shown, the coil spring 4 is located inside the accommodating cavity 211, which can protect the coil spring 4 structure and prevent other structural components from affecting the retraction of the coil spring 4. The coil spring 4 provides power for the retraction of the cable.

[0044] When the cable is pulled out, the friction between the cable and the cable reel 2 drives the cable reel 2 to rotate, continuously releasing the cable and pulling the coil spring 4 to extend.

[0045] This embodiment provides a specific implementation of a claw assembly:

[0046] See also Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, the claw assembly includes a dial wheel 31, a rotating piece 34, an elastic reset member 33 and a fixed plate 32, wherein: one end of the fixed plate 32 is fixed to the rotating shaft 6, and the other end of the fixed plate 32 is fixedly connected to the first end of the elastic reset member 33; the dial wheel 31 is fixedly connected to the winding reel 2, and the rotating piece 34 is rotatably connected to the fixed plate 32, and one end of the rotating piece 34 is fixedly connected to the second end of the elastic reset member 33; a one-way ratchet 311 is provided on the dial wheel 31, and a plurality of one-way ratchet teeth 311 are provided around the axis of the dial wheel 31. When the wire tube is pulled, the one-way ratchet teeth 311 can dial the rotating piece 34 to rotate, and when the external force is removed, the one-way ratchet teeth 311 can engage with one end of the rotating piece 34, thereby positioning the claw assembly and the winding reel 2. Figure 6 and Figure 7 As shown, the middle portion of the rotating piece 34 is rotatably connected to the fixed plate 32 via a rotating rod 35 .

[0047] The dial wheel 31 is fixed to the winding drum 2 and rotates synchronously with the winding drum 2. The rotating shaft 6 is fixed and stationary. The fixed plate 32 is fixed to the rotating shaft 6 and stationary. The elastic reset member 33 is a reset spring, which provides elastic force for the rotation and reset of the rotating piece 34.

[0048] When the cable is pulled out, the friction between the cable and the reel 2 drives the reel 2 to rotate, continuously releasing the cable and pulling the coil spring 4 to extend. Figure 7 As shown, Figure 7 The arrow in the figure indicates the direction of rotation of the cable reel 2. When in the next position, the one-way ratchet 311 activates the rotating piece 34. When the one-way ratchet 311 activates the rotating piece 34, the rotating piece 34 deflects about the rotating rod 35, making way for the rotation of the dial wheel 31. The cable reel 2 rotates under the pull of the cable, continuously releasing the cable. When the cable is pulled to the target length, the cable is pulled and the external force is removed. At this point, the teeth of the one-way ratchet 311 engage the end of the rotating piece 34, preventing the dial wheel 31 from rotating, and the cable extension length is fixed.

[0049] See also Figure 6 and Figure 7 As shown, the dial wheel 31 is further provided with a tooth-removing groove 312. The tooth-removing groove 312 and the one-way ratchet 311 are arranged around the axis of the dial wheel 31. When the cable reel 2 rotates until the end of the rotating plate 34 extends into the tooth-removing groove 312, the claw assembly is disengaged from the cable reel 2. The number of tooth-removing grooves 312 can be one or more. When there are more than two tooth-removing grooves 312, the tooth-removing grooves 312 are arranged at intervals around the axis of the dial wheel 31.

[0050] The function of the tooth groove 312 is as follows: Figure 6As shown, when the dial 31 rotates with the cable reel 2 until the end of the rotating piece 34 extends into the tooth withdrawal groove 312, the cable reel 2 and the claw assembly are in a disengaged state, that is, the claw assembly no longer positions the cable reel 2. At this time, the tension acting on the cable is removed, and the cable reel 2 can rotate under the elastic restoring force of the winding spring 4. Since the direction of rotation is opposite, the one-way ratchet 311 can no longer be positioned with the rotating piece 34.

[0051] As an alternative embodiment, see Figure 1 As shown, rollers 12 are provided on opposite sides of the cable outlet 11 , and the rollers 12 are rotatably connected to the side walls of the cable outlet 11 to prevent the cables from being scratched.

[0052] As an alternative embodiment, see Figure 1 As shown, a mounting bracket 5 is fixed on the housing 1, and the mounting bracket 5 is used to be fixed on the device to be fixed, so as to facilitate the fixed installation of the device.

[0053] When the wire tube retractor of this embodiment is used:

[0054] When the cable is pulled out, the friction between the cable and the reel 2 drives the reel 2 to rotate, continuously releasing the cable and pulling the coil spring 4 to extend. Figure 7 As shown, Figure 7 The direction of the arrow in the figure represents the direction of rotation of the cable reel 2. In the next position, the one-way ratchet 311 can toggle the rotating piece 34. When the one-way ratchet 311 toggles the rotating piece 34, the rotating piece 34 deflects around the rotating rod 35, making way for the rotation of the dial 31. The cable reel 2 can rotate under the pull of the cable, continuously releasing the cable. When the cable is pulled out to the target length, the cable is pulled and the external force is removed. At this time, the teeth of the one-way ratchet 311 engage with the end of the rotating piece 34, and the rotating piece 34 blocks the rotation of the dial 31, and the cable extension length is fixed. Among them, at this time, the end of the rotating piece 34 is engaged with the one-way ratchet 311, and the end of the rotating piece 34 does not extend into the tooth-retracting groove 312, that is, the cable reel 2 and the claw assembly are in a positioned state.

[0055] After use, when the cable needs to be rewound, the user pulls the cable until the end of the rotating piece 34 extends into the tooth-retracting groove 312. When the user pulls the cable, there is a "clicking" sound when the rotating piece 34 engages with the one-way ratchet 311. When the end of the rotating piece 34 extends into the tooth-retracting groove 312, there is a noticeable sense of no obstruction and no "clicking" sound. This is perceptible to the user when pulling the cable. When the dial 31 rotates with the cable reel 2 until the end of the rotating piece 34 extends into the tooth-retracting groove 312, the tension on the cable is removed, and the cable reel 2 can rotate under the elastic restoring force of the winding spring 4. Since the rotation direction is opposite, the one-way ratchet 311 can no longer be positioned with the rotating piece 34. In other words, the cable reel 2 and the claw assembly are disengaged, and the claw assembly no longer positions the cable reel 2.

[0058] The cable reel can be fixed to the side or top of the parking space to facilitate the retraction of the charging pile cable and ensure the safety of electricity use.
