[0025] In order to better understand the purpose, structure and function of the utility model, the photovoltaic cable anti-pull safety device of the utility model is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a photovoltaic cable anti-pulling safety device of the utility model comprises an electronic device 1 and a cable body 11, the right sides of the electronic device 1 are fixedly connected with fixing blocks 2, and the right side of the fixing block 2 is adapted to the left side of the fixing plate 3, the right side of the electronic device 1 is fixedly connected with a socket 20, the left end of the cable body 11 is fixedly connected with a plug 19, the left end of the outer side of the cable body 11 is fixedly connected with a mounting shell 4, the upper and lower sides of the inner side of the mounting shell 4 are rotatably connected with a fixing plate 3, the right side of the fixing plate 3 is fixedly connected with a No. 1 extrusion block 5, and the right end of the mounting shell 4 is installed with a clamping mechanism for clamping the fixing plate 3;

[0027] The clamping mechanism includes a No. 2 sleeve 9 fixedly connected to the right end of the mounting shell 4, the No. 1 sleeve 7 is slidably connected to the outside of the No. 2 sleeve 9, the upper and lower sides of the inner wall of the No. 1 sleeve 7 are fixedly connected with a movable plate 6, the left side of the movable plate 6 is in contact with the left wall of the slide groove 15, the right end of the No. 1 sleeve 7 is fixedly connected with a push plate 14, the interior of the No. 2 sleeve 9 is provided with a slide groove 15, the interior of the slide groove 15 is fixedly connected with a No. 1 spring 16, and the No. 1 spring 16 is sleeved on the outside of the No. 2 sleeve 9.

[0028] When using the device, the push plate 14 is pulled rightward to drive the No. 1 sleeve 7 to move rightward. When the No. 1 sleeve 7 moves, the movable plate 6 is driven to move rightward and squeeze the No. 1 spring 16, so that the No. 1 spring 16 is in a compressed state, and the No. 1 sleeve 7 is separated from the interior of the No. 1 squeezing block 5, so that the fixed plate 3 rotates, so that the No. 2 spring 18 is reset, and the left side of the fixed plate 3 is not in contact with the fixed block 2;

[0029] Next, insert the plug 19 into the socket 20, and then pull the push plate 14 to the left. Under the reaction of the No. 1 spring 16, the movable plate 6 is driven to move to the left, thereby driving the No. 1 sleeve 7 to move to the left, so that the No. 1 sleeve 7 enters the No. 1 extrusion block 5 again, drives the fixed plate 3 to rotate, and squeezes the No. 2 spring 18, so that the left side of the fixed plate 3 fits with the fixed block 2, thereby achieving a firm connection to the cable body 11, increasing the tensile resistance of the photovoltaic cable, and improving the use effect of the photovoltaic cable.

[0030] like Figure 1 and Figure 2 as well as Figure 3 As shown, the right end of the No. 2 sleeve 9 is fixedly connected to a limit plate 10 , which limits the push plate 14 to prevent excessive pulling force from causing the No. 1 sleeve 7 to separate from the outside of the No. 2 sleeve 9 .

[0031] like Figure 1 and Figure 2 as well as Figure 3As shown, the right end of the limit plate 10 is fixedly connected with two rings 12, and the two rings 12 are sleeved on the outside of the cable body 11. A connecting rod 13 is fixedly connected between the two cable bodies 11 to fix the cable body 11 and ensure that the cable body 11 is in a horizontal state to prevent the cable body 11 from bending and causing damage.

[0032] like Figure 2 and Figure 3 As shown, grooves 17 are provided on the upper and lower sides of the interior of the mounting shell 4, and a No. 2 spring 18 is fixedly connected to the interior of the groove 17, and the end of the No. 2 spring 18 facing away from the cable body 11 is fixed to the lower surface of the fixing plate 3. When the No. 1 sleeve 7 is separated from the interior of the No. 1 extrusion block 5, the No. 2 spring 18 can push the fixing plate 3 to expand outward, so as to facilitate the installation or removal of the No. 1 sleeve 7.

[0033] like Figure 2 and Figure 3 As shown, the lower part of the No. 1 extrusion block 5 is provided with an inclined surface matching the left end of the No. 1 sleeve 7 , and the installation or removal of the No. 1 sleeve 7 is performed with reduced friction through the inclined surface.

[0034] The working principle of the photovoltaic cable anti-pull safety device is as follows: when using the device, the push plate 14 is pulled to the right, driving the No. 1 sleeve 7 to move rightward. When the No. 1 sleeve 7 moves, the moving plate 6 is driven to move rightward and squeeze the No. 1 spring 16, so that the No. 1 spring 16 is in a compressed state, and the No. 1 sleeve 7 is separated from the inside of the No. 1 squeezing block 5, so that the fixed plate 3 rotates, so that the No. 2 spring 18 is reset, and the left side of the fixed plate 3 does not contact the fixed block 2;

[0035] Next, insert the plug 19 into the socket 20, and then pull the push plate 14 to the left. Under the reaction of the No. 1 spring 16, the movable plate 6 is driven to move to the left, thereby driving the No. 1 sleeve 7 to move to the left, so that the No. 1 sleeve 7 enters the No. 1 extrusion block 5 again, drives the fixed plate 3 to rotate, and squeezes the No. 2 spring 18, so that the left side of the fixed plate 3 fits with the fixed block 2, thereby achieving a firm connection to the cable body 11, increasing the tensile resistance of the photovoltaic cable, and improving the use effect of the photovoltaic cable.
