[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The present invention provides a quick-installable new energy cable as shown in Figures 1-5 which includes a joint body 1, a cable body 2 and an external thread cylinder 3. One end of the external thread cylinder 3 is fixedly connected to the joint body 1. A first ring 4 is slidably arranged inside the external thread cylinder 3. An elastic mechanism is arranged inside the external thread cylinder 3. The first ring 4 is slidably arranged inside the external thread cylinder 3 through the elastic mechanism. A plurality of elastic metal sheets 5 evenly distributed in a ring shape are fixedly arranged at the left end of the first ring 4. An electrical connection mechanism is also arranged inside the external thread cylinder 3. The plurality of elastic metal sheets 5 are electrically connected to the joint body 1 through the electrical connection mechanism. A pressing rod 6 is fixedly arranged at the left end of each elastic metal sheet 5. The left ends of the plurality of pressing rods 6 open outwards. A second ring 7 is also arranged inside the external thread cylinder 3. The second ring 7 is arranged on the left side of the first ring 4 and sleeved outside the plurality of elastic metal sheets 5. An internal thread cylinder 8 is threadedly sleeved outside the external thread cylinder 3. Two strip-shaped openings symmetrically distributed front and back are formed in the circumferential side wall of the external thread cylinder 3. Connecting rods 9 are slidably arranged in both strip-shaped openings. Opposite ends of the two connecting rods 9 are fixedly connected to the outer circumferential side wall of the second ring 7. A bearing is installed on the inner circumferential side wall of the internal thread cylinder 8. Opposite ends of the two connecting rods 9 are fixedly connected to the inner ring of the bearing. The wiring end of the cable body 2 passes through the first ring 4 and is located among the plurality of elastic metal sheets 5.

[0026] As shown in Figure 2 and Figure 3As shown, the electrical connection mechanism includes an annular metal sheet 10, a strip-shaped metal sheet 11, and an elastic metal telescopic rod 12. An annular cavity is provided inside the side wall of the first ring 4. The annular metal sheet 10 is fixedly arranged in the annular cavity. A plurality of round holes are provided on the left side of the annular cavity. A metal rod 13 is fixedly arranged in each round hole. The left ends of the plurality of metal rods 13 are respectively fixedly connected to a plurality of elastic metal sheets 5, and the right ends of the plurality of metal rods 13 are fixedly connected to the annular metal sheet 10. A round opening is provided on the outer circular side plate of the annular cavity. The elastic metal telescopic rod 12 is arranged in the round opening. A strip-shaped groove is provided on the upper inner side wall of the external thread cylinder 3. The strip-shaped metal sheet 11 is fixedly arranged in the strip-shaped groove. One end of the elastic metal telescopic rod 12 is fixedly connected to the annular metal sheet 10, and the other end of the elastic metal telescopic rod 12 abuts against and is slidably arranged with the strip-shaped metal sheet 11. One end of the strip-shaped metal sheet 11 is electrically connected to the joint body 1, which can keep the plurality of elastic metal sheets 5 in electrical connection with the strip-shaped metal sheet 11, so that the plurality of elastic metal sheets 5 are electrically connected to the joint body 1. When the connection end of the cable body 2 is connected to the plurality of elastic metal sheets 5, the cable body 2 is electrically connected to the joint body 1.

[0027] As Figure 2 , Figure 3 and Figure 5 shown, an arc-shaped metal sheet 17 is fixedly arranged on the inner side of each elastic metal sheet 5, which can expand the contact area between the elastic metal sheet 5 and the connection end of the cable body 2 and improve the stability of pressing the connection end of the cable body 2.

[0028] As Figure 2 and Figure 3 shown, a plurality of top blocks 14 evenly distributed in a ring shape are fixedly arranged on the inner circular side wall of the second ring 7. The plurality of top blocks 14 respectively abut against and are slidably arranged with the plurality of elastic metal sheets 5. The end of the top block 14 close to the elastic metal sheet 5 is arranged in a round head shape, which is convenient for pressing the plurality of pressure rods 6.

[0029] As Figure 2 and Figure 3As shown, the elastic mechanism includes two sliders 15 and two springs 16. The inner circular side wall of the external thread cylinder 3 is provided with two symmetrically distributed chutes in the front and back. The two chutes are respectively located on the right side of the two strip-shaped openings. The two sliders 15 are respectively slidably arranged in the two chutes. The two sliders 15 are both fixedly connected to the outer circular side wall of the first ring 4. The two springs 16 are respectively arranged in the two chutes. The left ends of the two springs 16 are respectively fixedly connected to the right ends of the two sliders 15. The right ends of the two springs 16 are respectively fixedly connected to the right side walls of the two chutes. When the cable main body 2 is pulled by an external force, the cable main body 2 will drive the first ring 4 to slide to the right through a plurality of elastic metal sheets 5. Thus, the springs 16 and the sliders 15 can buffer the first ring 4 and reduce the damage caused by the cable main body 1 being pulled. And as the plurality of pressure rods move to the right due to the pulling, the plurality of elastic metal sheets 5 will press the connection end of the cable main body 2 more firmly to avoid falling off.

[0030] As Figure 1 shown, the outer circular side wall of the internal thread cylinder 8 is provided with anti-slip lines, which is convenient for people to rotate the internal thread cylinder 8.

[0031] When the present invention is connected and installed, the connection end of the cable main body 2 is inserted into the external thread cylinder 3, passes through the first ring 4 and is inserted between a plurality of elastic metal sheets 5. Then the internal thread cylinder 8 is rotated. Since the internal thread cylinder 8 and the external thread cylinder 3 are threadedly sleeved, rotating the internal thread cylinder 8 can make the internal thread cylinder 8 move to the left. The internal thread cylinder 8 drives the second ring 7 to move to the left through two connecting rods 9. The second ring 7 moving to the left will squeeze a plurality of pressure rods 6. The plurality of pressure rods 6 will drive a plurality of elastic metal sheets 5 to close together towards the middle, thereby pressing the connection end of the cable main body 2. As the second ring 7 moves to the left, the plurality of elastic metal sheets 5 press the connection end of the cable main body 2 more firmly. When it is necessary to disassemble the cable main body 2, directly rotate the internal thread cylinder 8 in the reverse direction to drive the second ring 7 to move to the right, and the plurality of elastic metal sheets 5 will reset and open, so that the connection end of the cable main body 2 can be pulled out. Through the above device, it is not only convenient to stably connect and disassemble the cable main body 2 and the joint main body 1, but also the connection end of the cable main body 2 is pressed from all around by a plurality of elastic metal sheets 5, avoiding damage to the connection end of the cable and being convenient for people to use.

[0032] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
