DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] In one embodiment, see Figure 1 , Figure 2 and Figure 3 A quick junction box for power construction comprises a junction box body 1, two relatively distributed side walls of the junction box body 1 are provided with symmetrically distributed wiring holes 2, a wiring cavity 6 is provided inside the junction box body 1, and symmetrically distributed slots 5 are provided on both sides of the wiring cavity 6, the wiring hole 2 passes through the slot 5 and extends into the wiring cavity 6, a conductive sheet 7 is fixed on the inner wall of the wiring cavity 6, a trapezoidal block 8 is provided inside the wiring cavity 6, a threaded rod 3 passes through the trapezoidal block 8, the threaded rod 3 is threadedly connected to the trapezoidal block 8, the threaded rod 3 passes through the top of the junction box body 1 and is rotatably connected to the top of the junction box body 1, and a storage mechanism 4 is provided inside the slot 5, and the storage mechanism 4 is used to collect the cables outside the junction box body 1 into the junction box body 1.

[0023] In this embodiment, when connecting the cables, the ends of the two cables are first stripped to expose the wire cores inside the cables, and then the ends of the two cables are respectively inserted into the inside of the junction box body 1 from the wiring holes 2 on both sides of the junction box body 1. The cable ends first pass through the inside of the slot 5 and then enter the inside of the wiring cavity 6. At this time, the threaded rod 3 is rotated, and the trapezoidal block 8 is driven to move downward through the threaded connection between the threaded rod 3 and the trapezoidal block 8. While the trapezoidal block 8 moves downward, it first squeezes the cable end through its inclined surface, so that the cable end is bent toward the inner wall of the wiring cavity 6. As the trapezoidal block 8 continues to move, the side wall of the trapezoidal block 8 will have an squeezing effect on the cable end, thereby pressing the wire core inside the cable against the surface of the conductive sheet 7 on the side wall of the wiring cavity 6. The docking of two cables can be achieved, the structure is simple, and it is convenient for workers to quickly connect the cables, which effectively improves the efficiency of power construction. The trapezoidal block 8 can squeeze the cable while pressing the core against the surface of the conductive sheet 7. The core is squeezed and fixed by the side wall of the trapezoidal block 8, which can effectively improve the stability of the cable, thereby improving the tensile strength of the cable. At the same time, the trapezoidal block 8 can also bend the cable, thereby increasing the friction between the cable and the inner wall of the wiring cavity 6, and further improving the tensile strength of the cable. After the cable connection is completed, the cable outside the junction box body 1 is collected into the inside of the junction box body 1 through the storage mechanism 4 inside the slot body 5, which improves the aesthetic performance and also reduces the potential safety hazard caused by the excessive length of the cable outside the junction box body 1.

[0024] See also Figure 3 The inner wall of the wiring cavity 6 is provided with symmetrically distributed slide grooves 10, and the outer side of the trapezoidal block 8 is fixed with symmetrically distributed sliders 11, and the sliders 11 are located inside the slide grooves 10 and are slidably connected to the slide grooves 10; As the trapezoidal block 8 moves, the slider 11 on its side wall is driven to slide inside the slide groove 10. The slide groove 10 limits the trapezoidal block 8 through the slider 11, thereby preventing the threaded rod 3 from rotating and driving the trapezoidal block 8 to rotate, thereby ensuring the stability of the trapezoidal block 8 when moving.

[0025] See also Figure 2 and Figure 4 The storage mechanism 4 includes a threading ring 41 arranged inside the groove body 5, a support rod 42 is fixed on the top of the threading ring 41, a slideway 43 is provided on the inner wall of the groove body 5, and the end of the support rod 42 is located inside the slideway 43 and is slidably connected to the slideway 43, wherein one end of the support rod 42 located inside the slideway 43 is connected to a traction assembly, and the traction assembly is used to pull the support rod 42; The cable passes through the groove body 5 and the threading ring 41 at the same time. When the cable is connected, the support rod 42 is pulled by the traction component, so that the support rod 42 slides inside the slide 43. The support rod 42 moves while also driving the threading ring 41 to move. The threading ring 41 moves while pulling the cable, thereby pulling the cable located outside the junction box body 1 into the junction box body 1, thereby storing the cable, improving the aesthetic performance, and reducing safety hazards to a certain extent.

[0026] See also Figure 4 , an anti-slip ring 44 is fixed on the inner wall of the slideway 43, and the support rod 42 is slidably connected to the inner wall of the anti-slip ring 44; The provision of the anti-slip ring 44 can improve the friction performance between the support rod 42 and the slideway 43, thereby ensuring the stability of the support rod 42 and further improving the stability of the threading ring 41, wherein the anti-slip ring 44 can be made of rubber.

[0027] See also Figure 2 and Figure 4 The traction assembly includes a wire groove 46 arranged at the end of the slide 43, and the other end of the wire groove 46 extends to the inside of the wiring chamber 6. A baffle 9 is fixed inside the wiring chamber 6, and a rotating ring 413 runs through the inside of the baffle 9. The rotating ring 413 is rotatably connected to the baffle 9. A symmetrically distributed traction rope 45 is fixed to the outside of the rotating ring 413. The traction rope 45 passes through two wire grooves 46 respectively and is fixedly connected to the ends of the two support rods 42, wherein the rotating ring 413 is connected to a rotating component, and the rotating component is used to drive the rotating ring 413 to rotate; When the cables are connected, the rotating ring 413 is driven to rotate by the rotating component. While the rotating ring 413 rotates, the support rod 42 is pulled by the traction rope 45, thereby driving the support rod 42 to slide inside the slide 43. The structure is simple, which is convenient for the staff to quickly store the cables. The wire groove 46 can play a guiding role for the traction rope 45, so that the support rod 42 can be subjected to vertical force.

[0028] See also Figure 5 The rotating component includes a limiting groove 410 arranged on the inner wall of the rotating ring 413 and distributed in a circumferential manner, and the side wall of the threaded rod 3 is penetrated by a limiting block 49 which is symmetrically distributed. One end of the limiting block 49 located inside the threaded rod 3 is rotatably connected to a connecting rod 48, and the connecting rod 48 is rotatably connected to a push rod 47, and the push rod 47 passes through the top of the threaded rod 3; When the cable is connected, the push rod 47 is pressed downward. While the push rod 47 moves downward, it drives the two limit blocks 49 to move relative to each other through the connecting rod 48 until the ends of the two limit blocks 49 enter into one of the limit grooves 410 on the inner wall of the rotating ring 413. After the end of the limit block 49 enters the limit groove 410, the threaded rod 3 continues to rotate. At this time, the threaded rod 3 drives the rotating ring 413 to rotate through the cooperation of the limit block 49 and the limit groove 410, and then drives the support rod 42 to move through the traction rope 45. When the cable is stored, the push rod 47 is reset, and the limit block 49 automatically moves to the outside of the limit groove 410, losing the fixation of the limit block 49. When the cable is subjected to external tension, the cable will pull the threading ring 41, and the cable will move to the outside of the junction box body 1, which can play a wire-releasing role for the cable, so that the cable has a certain buffer length, thereby avoiding the cable from breaking when the cable is subjected to external tension, or the loosening between the cable and the conductive sheet 7, further improving the safety performance.

[0029] See also Figure 5 A pressing plate 411 is fixed to one end of the push rod 47 located inside the threaded rod 3, and the pressing plate 411 is slidably connected to the inner wall of the threaded rod 3, wherein an elastic member 412 is fixed to the bottom of the pressing plate 411, and the other end of the elastic member 412 is fixedly connected to the bottom of the threaded rod 3; When the cables are stored, the staff no longer presses the push rod 47, and the push rod 47 can automatically reset under the action of the pressure plate 411 and the elastic member 412, wherein the elastic member 412 can be a spring, and the pressure plate 411 can limit the push rod 47, thereby improving the stability of the push rod 47 when moving.

[0030] See also Figure 1 , a handle 12 symmetrically distributed is fixed to the upper end of the side wall of the threaded rod 3; The arrangement of the handle 12 makes it convenient for the worker to press the push rod 47 downward while rotating the threaded rod 3 .

[0031] Working principle: When connecting the cables, the ends of the two cables are respectively inserted into the inside of the junction box body 1 from the wiring holes 2 on both sides of the junction box body 1. The cable ends first pass through the inside of the slot 5 and then enter the inside of the wiring cavity 6. Then, the threaded rod 3 is rotated, and the threaded connection between the threaded rod 3 and the trapezoidal block 8 drives the trapezoidal block 8 to move downward. While the trapezoidal block 8 moves downward, it first squeezes the cable ends through its inclined surface, so that the cable ends are bent toward the inner wall of the wiring cavity 6. As the trapezoidal block 8 continues to move, the side wall of the trapezoidal block 8 will have an squeezing effect on the cable ends, thereby squeezing the inside of the cable. The wire core is pressed against the surface of the conductive sheet 7 on the side wall of the wiring cavity 6, which plays a quick connection role for the two cables, and the wire core is squeezed and fixed by the side wall of the trapezoidal block 8, which can effectively improve the stability of the cable, thereby improving the tensile strength of the cable. At the same time, the trapezoidal block 8 can also bend the cable, thereby increasing the friction between the cable and the inner wall of the wiring cavity 6, further improving the tensile strength of the cable. After the cable connection is completed, the push rod 47 is pressed downward, and the push rod 47 drives the two limit blocks 49 to move relative to each other through the connecting rod 48, so that the ends of the two limit blocks 49 enter the rotating ring 41 3, the end of the limit block 49 enters the limit groove 410 and then continues to rotate the threaded rod 3. At this time, the threaded rod 3 drives the rotating ring 413 to rotate through the cooperation of the limit block 49 and the limit groove 410. The rotating ring 413 pulls the support rod 42 through the traction rope 45, and the support rod 42 pulls the cable through the threading ring 41, so that the cable outside the junction box body 1 is pulled into the inside of the junction box body 1, thereby playing a storage role for the cable, improving the aesthetic performance, and at the same time, to a certain extent, it can also reduce the safety hazards caused by the excessive length of the cable outside the junction box body 1. To solve the hidden danger problem, when the cables are stored, the staff on the support rod 42 no longer presses the push rod 47, and the push rod 47 automatically resets under the action of the elastic member 412, and the limit block 49 automatically moves to the outside of the limit groove 410. Without the fixation of the limit block 49, when the cables are subjected to external tension, the cables will pull the threading ring 41, and the cables will move to the outside of the junction box body 1, which can play a role in releasing the cables, so that the cables have a certain buffer length, thereby avoiding the cable from breaking when subjected to external tension, or the cable from loosening with the conductive sheet 7, further improving the safety performance.
