Description

Technical Field

[0001] The invention relates to the field of chargers, and in particular to a charger with a wire end anti-falling function. Background Art

[0002] The charger adopts high-frequency power supply technology and uses advanced intelligent dynamic adjustment charging technology.

[0003] When using a traditional charger, it is used in conjunction with a charging cable and a charging head. However, the charging cable and the charging head are prone to fall off after being slightly stressed, resulting in low practicality of the charger. Therefore, in order to solve this problem, we propose a charger with a cable head anti-falling function. Summary of the invention

[0004] The present invention provides a charger with a wire head anti-falling function, which solves the problem that the existing charger wire and charger head are easy to fall off when slightly stressed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A charger with a cable end anti-falling function comprises a charging head, a metal plug and a charging cable, wherein two symmetrically distributed metal plugs are fixedly mounted on one side of the charging head, and a socket matching the end of the charging cable is provided on the other side of the charging head, two symmetrically distributed cross plates are fixedly connected to one side of the charging head close to the socket, and an adjustment ring is slidably sleeved between the two cross plates, two symmetrically distributed latches are fixedly connected between the inner walls on both sides of the adjustment ring, and the two latches are respectively slidably mounted inside the two cross plates, and an anti-falling positioning device is provided on the cross plate.

[0007] Preferably, the anti-falling positioning device includes a rotating rod, a rotating groove, a movable groove, a movable plate and positioning teeth. The horizontal plate is provided with a movable groove, and a movable plate is slidably installed in the movable groove. The movable plate passes through the movable groove. A rotating groove is provided in the middle position of a side of the horizontal plate away from the charging head, and a rotating rod is rotatably installed in the rotating groove, and the rotating rod is fixedly connected to one end of the movable plate.

[0008] Preferably, the movable plate is arranged in an arc shape, and the inner arc wall of the movable plate is evenly provided with positioning teeth matching with the latch teeth.

[0009] Preferably, rollers are rotatably mounted on the ends of the two rotating rods that are close to each other.

[0010] Preferably, a sliding groove is provided inside the transverse plate, and the latching tooth is slidably installed inside the sliding groove, and a return spring is fixedly connected between the latching tooth and the inner wall of the sliding groove.

[0011] Preferably, the slide groove and the movable groove are interconnected, and the slide groove is arranged to penetrate along the width direction of the transverse plate, and the two sides of the latching tooth are respectively fixedly connected to the two side inner walls of the adjustment ring.

[0012] The beneficial effects of the present invention are as follows: by pushing the end of the charging cable toward the back of the charging head and inserting it, the roller drives the rotating plate to rotate, and the movable plate can slide stably inside the movable groove until the end of the charging cable is stably inserted into the charging head, and the elastic force of the return spring pushes the latch tooth, so that the movable plate and the rotating rod can be kept stable as a whole, that is, the roller stably clamps and fixes the end of the charging cable, thereby effectively preventing the charging cable and the charging head from falling off due to slight force during use, thereby improving the practical performance of the charger and being suitable for popularization and use.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-4 A charger with a wire end anti-falling function comprises a charging head 1, a metal plug-in sheet 2 and a charging line 3, two symmetrically distributed metal plug-ins 2 are fixedly installed on one side of the charging head 1, and a socket matching the end of the charging line 3 is provided on the other side of the charging head 1, two symmetrically distributed horizontal plates 4 are fixedly connected to one side of the charging head 1 close to the socket, and an adjusting ring 5 is slidably sleeved between the two horizontal plates 4, two symmetrically distributed latch teeth 12 are fixedly connected between the inner walls on both sides of the adjusting ring 5, and the two latch teeth 12 are respectively slidably installed inside the two horizontal plates 4, and an anti-falling positioning device is provided on the horizontal plate 4.

[0020] The anti-falling positioning device includes a rotating rod 7, a rotating groove 8, a movable groove 9, a movable plate 6 and a positioning tooth 11. A movable groove 9 is provided on the transverse plate 4, and a movable plate 6 is slidably installed in the movable groove 9. The movable plate 6 passes through the movable groove 9. A rotating groove 8 is provided in the middle position of the side of the transverse plate 4 away from the charging head 1, and a rotating rod 7 is rotatably installed in the rotating groove 8, and the rotating rod 7 is fixedly connected to one end of the movable plate 6. The movable plate 6 is arranged in an arc shape, and the inner arc wall of the movable plate 6 is evenly provided with positioning teeth 11 matching the latch teeth 12. The ends of the two rotating rods 7 close to each other are rotatably installed with rollers 10. A sliding groove 14 is provided inside the transverse plate 4, and the latch teeth 12 are slidably installed inside the sliding groove 14, and a reset spring 13 is fixedly connected between the latch teeth 12 and the inner wall of the sliding groove 14, the sliding groove 14 and the movable groove 9 are communicated with each other, and the sliding groove 14 is arranged to penetrate along the width direction of the transverse plate 4, and the two sides of the latch teeth 12 are respectively fixedly connected to the two side inner walls of the adjusting ring 5.

[0021] Working principle: When the device is in use, first pull the adjusting ring 5 to move it on the horizontal plate 4 to a position away from the charging head 1, and the adjusting ring 5 will drive the latch tooth 12 to move inside the slide groove 14, and squeeze the reset spring 13, so that the latch tooth 12 is separated from the positioning tooth 11, and then the end of the charging cable 3 is inserted into the back of the charging head 1. During the insertion process, the roller will rotate on the rotating rod 7, and the rotating rod 7 will rotate around the rotating shaft inside the rotating groove 8, so that the rotating rod 7 pushes the movable plate 6 until the end of the charging cable 3 is completely inserted into the charging head 1. After that, release the adjusting ring 5. At this time, the reset spring 13 will push the latch tooth 12 in the reverse direction, so that the latch tooth 12 moves in the reverse direction inside the slide groove 14 until the latch tooth 12 is stuck between two adjacent positioning teeth 11 on the movable plate 6, thereby keeping the movable plate 6, the rotating plate 7 and the roller 10 fixed, and the end of the charging cable 3 is fixed by the two rollers 10 to prevent it from falling off from the charging head 1.
