[0015] The present invention has the following beneficial effects: 1. In the distribution box, the first wire clamping mechanism and the second wire clamping mechanism are provided, so that the distance between the two first wire clamping wheels and the distance between the two second wire clamping wheels can be adjusted, so as to facilitate the clamping of the wires and increase the stability of the plug inserted into the socket. The wire wheel is provided, so that the wires can pass through the first wire clamping wheel, the wire wheel and the second wire clamping wheel for wiring, and the overall length of the wires inside the wiring box is increased. Therefore, when the wires are accidentally pulled by the outside world, the length of the wires passing through the first wire clamping wheel, the wire wheel and the second wire clamping wheel is changed through the tension within a certain range on the wires, so that the wires can be laid out first, and the leakage length of the wires is increased, so as to offset the tension and prevent the risk of the plug being accidentally pulled out of the socket.

[0016] 2. In the distribution box, when the tension on the wire exceeds a certain range, the second mounting seat will first drive the limit plate and the convex strip to move downward to the lowest position, that is, the limit plate moves to the bottom wall of the wiring box, and then the limit plate will not be able to move further. When the limit plate moves to the bottom wall of the wiring box, the first gear moves to a position meshing with the second gear. At this time, the rotation of the second clamping wheel can drive the first gear to rotate, and the first gear drives the second gear to rotate. The second gear drives the moving seat to move through the rack, and the moving seat drives the guide wheel to move, so that the guide wheel can move along the inclined groove, thereby further reducing the length of the wire passing through the first clamping wheel, the guide wheel and the second clamping wheel, increasing the wire pay-out length, and preventing the risk of the plug being pulled out of the socket when the tension of the wire exceeds a certain range.

[0017] 3. In the distribution box, when the tension of the wire exceeds a certain range and the wire wheel moves upward along the inclined groove, the third rotating shaft will contact the pressure plate, causing the pressure plate to slide in the inclined groove. The pressure plate squeezes the first air bag, causing the gas in the first air bag to enter the air cavity through the gas pipeline. After the air cavity is inflated, it presses the movable plate upward, and the movable plate drives the pressing column to press the first mounting seat upward, so that the first mounting seat presses the plug of the wire tightly into the socket, thereby further increasing the stability of the connection between the plug and the socket and reducing the possibility of the plug being accidentally pulled out of the socket.

[0018] 4. In the distribution box, when the tension of the wire exceeds a certain range, the first airbag will continue to move upward along the inclined groove, so that the first airbag that has been squeezed and exhausted will be inflated again, so that the gas inside the air cavity becomes less, causing the clamping column to no longer press against the first mounting seat. After the first mounting seat loses its supporting force, the plug can be pulled out of the socket at this time, thereby preventing the plug from being inserted into the socket when the tension of the wire is too large, causing the plug to pull the socket, causing the socket to pull the distribution box body, causing the distribution box body to be pulled and deformed, which is beneficial to increase the protection of the distribution box body.

A first spring 11 is fixed on the fixing box 8, and the top of the first spring 11 is fixedly connected to the first wire clamping mechanism 10. A wire wheel 12 for winding the wire 4 is rotatably provided on the side plate 9. A second wire clamping mechanism 13 for clamping the wire 4 is also provided in the wiring box 3. The second wire clamping mechanism 13 is used to release the wire 4 when the wire 4 is pulled. A second spring 14 is provided in the wiring box 3, and the top of the second spring 14 is fixedly connected to the second wire clamping mechanism 13. The first clamping mechanism 10 comprises a first mounting seat 101 connected to the first spring 11, on which two first clamping wheels 102 with adjustable spacing are rotatably arranged, and the first clamping wheels 102 are elastically connected to the first mounting seat 101; A first adjusting block 103 is slidably disposed in the first mounting seat 101, a first adjusting bolt 104 is threadedly connected to the first mounting seat 101, an end of the first adjusting bolt 104 is rotatably connected to the first adjusting block 103, a first rotating shaft 105 is fixed to the first clamping wheel 102, and the first rotating shaft 105 is fixed to the first adjusting block 103; The second clamping mechanism 13 includes a second mounting seat 131 connected to the second spring 14, a first slide rail 132 is fixed on the inner wall of the wiring box 3, the second mounting seat 131 is slidably connected to the first slide rail 132, two second clamping wheels 133 with adjustable spacing are rotatably provided on the second mounting seat 131, and the second clamping wheel 133 is elastically connected to the second mounting seat 131; A second adjusting block 134 is slidably arranged in the second mounting seat 131, a second adjusting bolt 135 is threadedly connected to the second mounting seat 131, an end of the second adjusting bolt 135 is rotatably connected to the second adjusting block 134, a second rotating shaft 136 is fixed to the second clamping wheel 133, the second rotating shaft 136 is rotatably arranged on the second adjusting block 134, a torsion spring 137 is sleeved on the circumference of the second rotating shaft 136, and two ends of the torsion spring 137 are respectively fixed to the inner side of the second clamping wheel 133 and the circumference of the second adjusting block 134; In the present technical solution, a box door is provided on the outside of the wiring box 3. When wiring, the box door is first opened, and the wire 4 is inserted into the wiring box 3 from the bottom of the wiring box 3, and then the first clamping mechanism 10 is pulled downward with force to move the first mounting seat 101 downward, compressing the first spring 11. The first spring 11 accumulates force, and at this time, the plug 7 of the wire 4 is inserted into the socket 6, and then the first clamping mechanism 10 is released, the first spring 11 releases force, and the first mounting seat 101 is reset, and then the wire 4 passes through the first clamping wheel 102, the wire wheel 12 and the second clamping wheel 133 (such as Figure 2As shown), the first adjusting bolt 104 is then rotated to drive the first adjusting block 103 to move, and the movement of the first adjusting block 103 drives one of the first clamping wheels 102 to approach the other first clamping wheel 102, so that the first clamping wheel 102 clamps the wire 4 tightly, and when the wire 4 passes through the second clamping wheel 133, the second adjusting bolt 135 is rotated to drive the second adjusting block 134 to move, and the second adjusting block 134 drives the two second clamping wheels 133 to approach each other, so that the second clamping wheel 133 clamps the wire 4 tightly, and the wiring is completed; When the wire 4 is pulled unexpectedly by the outside world and the tension of the wire 4 is within a certain range, due to the torsion spring 137 that is set, when the tension of the wire 4 is within a certain range, the torsion spring 137 does not work, so that the second clamping wheel 133 does not rotate. When the second clamping mechanism 13 clamps the wire 4, the wire 4 will first pull the second clamping wheel 133 to move downward. The second clamping wheel 133 moves downward, so that the second spring 14 is compressed. The second spring 14 accumulates force. After the second clamping wheel 133 moves downward, the wire 4 can be released to extend the length of the external wire 4, thereby preventing the risk of the plug 7 being pulled out of the socket 6 due to the accidental pulling of the wire 4 by the outside world. When the external force disappears, the second spring 14 releases the force to reset the second mounting seat 131.

[0033] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 11 A limit plate 15 is fixed on the inner surface of the second mounting seat 131, a convex strip 16 is fixed on the limit plate 15, a first gear 17 is fixed on the end of the second rotating shaft 136, a moving seat 18 is slidably provided at the bottom of the wiring box 3, a rack 19 is fixed on the moving seat 18, a second gear 20 is meshed on the rack 19, and the second gear 20 is rotatably provided on the inner wall of the wiring box 3, a lifting guide rod 21 is fixed on the moving seat 18, a lifting groove 22 is provided on the lifting guide rod 21, a lifting seat 23 is slidably provided in the lifting groove 22, a third rotating shaft 24 is fixed on the lifting seat 23, the wire wheel 12 is rotatably provided at the end of the third rotating shaft 24, an inclined groove 25 is provided on the side plate 9, the third rotating shaft 24 passes through the inclined groove 25, and is slidably connected with the inclined groove 25; A second slide rail 26 is fixed to the bottom of the wiring box 3, and the movable seat 18 is slidably arranged on the second slide rail 26; In the present technical solution, when the tension of the wire 4 exceeds a certain range, the second mounting seat 131 will first drive the limit plate 15 and the convex strip 16 to move downward to the lowest position, that is, the limit plate 15 moves to the bottom wall of the wiring box 3, and then the limit plate 15 will not be able to move further. When the limit plate 15 moves to the bottom wall of the wiring box 3, the first gear 17 moves to a position meshing with the second gear 20. Due to the torsion spring 137, when the tension of the wire 4 exceeds a certain range, the torsion spring 137 is actuated to rotate the second clamping wheel 133. The torsion spring 137 accumulates force, and the rotation of the second clamping wheel 133 drives the first gear 17 to rotate. The rotation of the first gear 17 drives the second gear 20 to rotate, and the rotation of the second gear 20 drives the rack 1 9 moves, the rack 19 drives the moving seat 18 to slide on the second slide rail 26, the moving seat 18 slides, and the convex strip 16 is inserted into the notch 44 at the bottom of the moving seat 18. Due to the lifting groove 22 and the lifting seat 23 set on the lifting guide rod 21, when the moving seat 18 slides, the third rotating shaft 24 is restricted by the inclined groove 25, so that the third rotating shaft 24 drives the lifting seat 23 to slide upward in the lifting groove 22, so that the third rotating shaft 24 will slide along the inclined groove 25, and the third rotating shaft 24 slides along the inclined groove 25 to drive the wire wheel 12 to move upward. In this process, the wire release length of the wire 4 can be further increased, and when the pulling force of the wire 4 exceeds a certain range, the risk of pulling out the plug 7 from the socket 6 can be prevented; When the limit plate 15 moves to the bottom wall of the wiring box 3, the distance between the wire wheel 12 and the second wire clamping wheel 133 becomes shorter, so that the wire 4 between the wire wheel 12 and the second wire clamping wheel 133 becomes loose, and the loosened wire 4 can be instantly released by the rotation of the second wire clamping wheel 133, thereby increasing the leakage length of the wire 4, and it is not necessary to wait until the wire wheel 12 moves along the inclined groove 25 before starting the wire release process, which effectively prevents the wire wheel 12 from failing to slide along the inclined groove 25 in time, causing the wire 4 to be pulled and the plug 7 to loosen; When the external force disappears, the torsion spring 137 releases the force, causing the first gear 17 to reverse, and the reversal of the first gear 17 drives the second gear 20 to reverse, and the reversal of the second gear 20 drives the rack 19 to reset, and the rack 19 drives the moving seat 18 to reset. During the resetting process of the moving seat 18, since the convex strip 16 needs to be moved out of the notch 44 at the bottom of the moving seat 18, the notch 44 restricts the convex strip 16 during the process of the convex strip 16 moving out of the notch 44 at the bottom of the moving seat 18, so that the convex strip 16 cannot be reset upward, prompting the moving seat 18 to drive the third rotating shaft 24 to move downward along the inclined groove 25 first, so that the wire wheel 12 is reset first, and after the convex strip 16 moves out of the notch 44 at the bottom of the moving seat 18, the resetting of the wire wheel 12 is completed. After the convex strip 16 loses its restriction, it can move upward, and the torsion spring 137 and the second spring 14 continue to release the force to reset the second mounting seat 131.

[0034] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 11 A base 27, a first airbag 28 and a pressure plate 29 are slidably arranged in the inclined groove 25, one end of the first airbag 28 is fixed on the base 27, and the pressure plate 29 is in contact with the other end of the first airbag 28. A pad 30 for supporting the base 27 is elastically arranged in the inclined groove 25, an air cavity 31 is arranged inside the fixed box 8, a movable plate 32 is arranged in the air cavity 31, a second airbag 33 is arranged between the movable plate 32 and the bottom of the air cavity 31, a tightening column 34 is fixed on the movable plate 32, and the top of the tightening column 34 is in contact with the first mounting seat 101, an air delivery pipeline 35 is arranged between the first airbag 28 and the second airbag 33, and a receiving groove 36 for sliding the air delivery pipeline 35 is opened in the side plate 9; In the present technical solution, when the tension of the electric wire 4 exceeds a certain range, and when the third rotating shaft 24 slides along the inclined groove 25 to drive the wire wheel 12 to move upward, the third rotating shaft 24 will contact the pressure plate 29, so that the pressure plate 29 slides in the inclined groove 25, and the pressure plate 29 squeezes the first air bag 28, so that the gas in the first air bag 28 enters the second air bag 33 through the gas pipeline 35, and the second air bag 33 expands after being inflated and presses the movable plate 32 upward, and the movable plate 32 drives the pressing column 34 to press the first mounting seat 101 upward, so that the first mounting seat 101 presses the plug 7 of the electric wire 4 in the socket 6, thereby further increasing the stability of the connection between the plug 7 and the socket 6, and reducing the situation where the plug 7 is accidentally pulled out of the socket 6; when the external force disappears, the second air bag 33 is compressed by the movable plate 32 to exhaust and reset, and the gas inside the second air bag 33 is filled into the first air bag 28 through the gas pipeline 35, so that the first air bag 28 is reset; When the plug 7 is inserted into the socket 6, the first clamping mechanism 10 needs to be pulled downward with force to move the first mounting seat 101 downward. At this time, the abutting column 34 drives the movable plate 32 to move downward in the air cavity 31. Since the second airbag 33 is not fully filled with gas at the beginning, it can be deformed to a certain extent when subjected to external force, so the movable plate 32 can be guaranteed to move downward normally. A T-shaped limit groove 37 is opened on the side plate 9, and a T-shaped limit block 38 is fixed on the base 27 and the pressure plate 29, and the T-shaped limit block 38 is slidably set in the T-shaped limit groove 37; by sliding the T-shaped limit block 38 inside the T-shaped limit groove 37, the pressure plate 29 can only slide along the inclined groove 25 and will not slide out from the inclined groove 25.

[0035] Embodiment 4: When the pulling force of the wire 4 is too great, if the plug 7 is only prevented from being pulled out of the socket 6, when an unbearable pulling force occurs, the plug 7 will pull the socket 6, and the socket 6 will pull the distribution box body 1, causing the distribution box body 1 to be pulled and deformed, resulting in damage to the distribution box body 1 and cannot be used again. To address this problem, this embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-Figure 11 A contraction groove 39 is also provided in the side plate 9, a slide plate 40 is slidably provided in the contraction groove 39, a third spring 41 is fixed between the slide plate 40 and the bottom wall of the contraction groove 39, the end of the pad 30 is fixed on the slide plate 40, a triangular inclined block 42 is fixed on the pad 30, and a resisting rod 43 for resisting the triangular inclined block 42 is fixed on the T-shaped limit block 38 on the pressure plate 29; In the present technical solution, when the tension of the wire 4 exceeds a certain range, the pressure plate 29 will squeeze the first airbag 28 to a certain position, and the abutment rod 43 will slide upward along the T-shaped limit groove 37 (such as Figure 8 As shown), until the abutment rod 43 slides to only contact with the triangular inclined block 42 and does not conflict with the triangular inclined block 42, but when the tension of the wire 4 continues to increase, the tension of the wire 4 is too large, the abutment rod 43 continues to slide, and contacts with the triangular inclined block 42. Fig. 9 The triangular inclined block 42 in the air chamber 31 contacts the base 27, causing the triangular inclined block 42 to drive the pad 30 to slide, and the pad 30 drives the slide plate 40 to move into the contraction groove 39, compressing the third spring 41, so that the third spring 41 accumulates force. When the pad 30 is completely removed from the base 27, the base 27 loses its supporting force, and the gas inside the air cavity 31 rushes into the first air bag 28 through the air delivery pipe 35, causing the first air bag 28 to reset. The reset of the first air bag 28 causes the base 27 to move upward along the inclined groove 25, while driving the air delivery pipe 35 to move upward. 5 moves in the receiving groove 36 to prevent the gas delivery pipeline 35 from being broken. After the first airbag 28 is reset, the abutting column 34 no longer abuts against the first mounting seat 101. At this time, the first mounting seat 101 loses its supporting force. At this time, the plug 7 can be pulled out of the socket 6, thereby preventing the plug 7 from being inserted into the socket 6 when the tension of the wire 4 is too large, causing the plug 7 to pull the socket 6, causing the socket 6 to pull the distribution box body 1, causing the distribution box body 1 to be pulled and deformed, which is beneficial to increase the protection of the distribution box body 1; After the plug 7 is pulled out from the socket 6, the worker checks it and after confirming that there is no problem, the worker manually resets the first airbag 28 and inserts the plug 7 into the socket 6 again for continued use.
