The upper surfaces of the fixing plates are provided with notches. The upper ends of the short winding posts are provided with mounting grooves. The inner side of the mounting groove is rotatably connected with a retaining rod, and the other end of the retaining rod is engaged with the notch.

[0009] The sealing structure is used to enhance the sealing performance of the cable connection protection device to prevent water from entering the interior of the device and causing a short circuit;

[0013] It is further configured that the upper surface of the fixed plate is rotatably connected to a limiting member, the limiting member is L-shaped, a torsion spring is arranged between one end of the L-shape and the fixed plate, the other end of the L-shape is engaged with the retaining rod, the limiting member is located inside the torsion spring, and the torsion spring is sleeved outside the limiting member.

[0014] It is further configured that the cable power connection structure includes a mounting plate arranged at the bottom of the inner cavity of the cable power connection protection box, and a plurality of outer shells and copper conductive plates are fixedly installed on the upper surface of the mounting plate. The copper conductive plates are located inside the outer shells, and conductive seats are symmetrically fixedly installed on the upper surface of the copper conductive plates.

[0015] It is further configured that an arc groove and a groove are provided on the upper surface of the conductive seat, two grooves are provided on both sides of the arc groove and are connected to each other, a plurality of threaded holes are provided on the top of the outer shell, and the fastening bolts pass through the threaded holes and enter the interior of the outer shell and then rotate to connect to the lower pressure block, and a protrusion is provided on the lower surface of the lower pressure block, and the protrusion is engaged with the groove.

[0016] It is further provided that a receiving groove is provided at the bottom of the mounting plate, and more than two supporting rods are rotatably connected in the receiving groove.

[0017] It is further arranged that the inner cavity of the cable power connection protection box is symmetrically provided with insertion grooves, U-shaped seats are fixedly installed on both sides of the mounting plate, tension springs are fixedly installed on the inner sides of the two U-shaped seats, one end of the tension spring is fixedly connected to an insertion rod passing through the U-shaped seat, and one end of the insertion rod passes through the U-shaped seat and is inserted into the insertion groove.

Because the retaining rod on the top of the short winding post is stuck into the inside of the notch, and at the same time, the elastic deformation ability of the torsion spring is used to enable the limiter to limit the position of the retaining rod, thereby preventing the cable from escaping from the gap between the short winding post and the fixed plate. Such a serpentine wire passing path greatly enhances the cable's resistance to pulling, and solves the technical problem that the electrical engineering cable power connection protection device in the prior art has poor resistance to pulling and is prone to loosening and falling off when connecting to the power, thereby affecting the power-on effect.

By pulling the insertion rod, the tension spring is stretched, so that the insertion rod is separated from the interior of the insertion slot, so that the cable power connection structure can be moved upward. At the same time, under the action of gravity, the support rod is rotated to a vertical state, so that the cable power connection structure moved up to a certain height is supported and fixed. Compared with the operation in the narrow space of the cable power connection protection box, the cable power connection structure exposed on the top of the cable power connection protection box is easier to perform cable power connection operation, thereby improving the cable power connection efficiency.

[0033] Example 1

[0034] An electrical engineering cable connection protection device, such as Figure 1-3 As shown, including:

[0035] The cable power connection protection box 1 has a first cable pipe 12 and a second cable pipe 36 symmetrically fixedly connected to the left and right sides of the cable power connection protection box 1;

[0036] The anti-pull structure comprises two long winding poles 3, two short winding poles 4 and two fixing plates 5 symmetrically installed at the bottom of the inner cavity of the cable power connection protection box 1. The two fixing plates 5 are respectively arranged on one side of the first cable pipe 12 and the second cable pipe 36 and are close to the inner wall of the cable power connection protection box 1, and are lower than the first cable pipe 12 and the second cable pipe 36; a notch 20 is provided on the upper surface of the fixing plate 5, and a mounting groove 18 is provided on the upper end of the short winding pole 4. A retaining rod 19 is rotatably connected to the inner side of the mounting groove 18, and the other end of the retaining rod 19 is engaged with the notch 20. A limiting member 16 is rotatably connected to the upper surface of the fixing plate 5. The limiting member 16 is L-shaped. A torsion spring 17 is arranged between one end of the L-shaped member and the fixing plate 5. The other end of the L-shaped member is located at the top of the retaining rod 19 and is engaged with the retaining rod 19 (the retaining rod 19 is in close contact with the limiting member 16). The limiting member 16 is located inside the torsion spring 17, which can prevent the torsion spring 17 from bending and affecting the elastic deformation capacity;

[0037] The sealing structure is used to enhance the sealing performance of the cable power connection protection device to prevent water from entering the interior of the device and causing a short circuit; the sealing structure includes a buckle seat 2 installed and fixed on the front surface of the cable power connection protection box 1, a power connection box cover 9 is hinged on the upper surface of the cable power connection protection box 1, a buckle head engaged with the buckle seat 2 is fixedly installed on the upper surface of the power connection box cover 9, and also includes a rubber sealing ring 8, a rubber sleeve 14, and the rubber sleeve 14 on the inner side of the first cable pipe 12 and the second cable pipe 36 ensures the sealing performance of the connection between the first cable pipe 12, the second cable pipe 36 and the cable; a sealing groove 6 is provided on the upper surface of the cable power connection protection box 1, and a rubber sealing ring 8 engaged with the sealing groove 6 is fixedly installed on the lower surface of the power connection box cover 9; the rubber sealing ring 8 is inserted into the sealing groove 6 to help enhance the sealing performance of the connection between the power connection box cover 9 and the cable power connection protection box 1;

[0038] The cable power connection structure connects the two cables passing through the first cable tube 12 and the second cable tube 36 to electricity. In this embodiment, the cable power connection structure is a conventional conductive sheet.

[0039] When the device of this embodiment is in use, the two cables are first passed through the first cable tube 12 and the second cable tube 36 respectively into the interior of the cable power connection protection box 1, and the cables are successively passed through the gap between the short winding column 4 and the fixing plate 5, and the gap between the short winding column 4 and the long winding column 3, and the retaining rod 19 is stuck into the interior of the notch 20. Moreover, under the elastic deformation capacity of the torsion spring 17, one end of the limiter 16 limits the position of the retaining rod 19 to prevent the cable from escaping from the gap between the short winding column 4 and the fixing plate 5, and then the two cables are connected using the cable power connection structure. The serpentine wire passing path of the cable of this embodiment greatly enhances the cable's anti-pulling ability, and solves the problem that the electrical engineering cable power connection protection device in the prior art usually presses the conductive connecting ends of the two cables onto the conductive sheet or fixes them by winding the connecting ends when connecting to the power. Although this achieves power connection, it has poor anti-pulling ability and is prone to loosening and falling off, affecting the power-on effect.

[0040] Example 2

[0041] Based on Example 1, an electrical engineering cable connection protection device, such as Figure 4-7 As shown, the cable power connection structure includes a mounting plate 11 arranged at the bottom of the inner cavity of the cable power connection protection box 1, and five outer shells 13 and copper conductive plates 22 are fixedly installed on the upper surface of the mounting plate 11. The copper conductive plates 22 are located inside the outer shell 13, and two conductive seats 23 are symmetrically fixedly installed on the upper surface of the copper conductive plates 22;

[0042] An arc groove 25 and two grooves 34 are provided on the upper surface of the conductive seat 23. Two grooves 34 are provided on both sides of the arc groove 25 and the three grooves are connected to each other. A plurality of threaded holes are provided on the top of the outer shell 13. The fastening bolt 21 passes through the threaded holes and enters the inner part of the outer shell 13 and then rotates to connect the lower pressing block 24. A convex block 35 is provided on the lower surface of the lower pressing block 24. The convex block 35 is engaged with the groove 34. After the two cables are combined, they are fixed in the arc groove 25.

[0043] A receiving groove 27 is provided at the bottom of the mounting plate 11, and two support rods 26 are symmetrically rotatably connected at both ends of the receiving groove 27. The two support rods 26 can be folded and put into the receiving groove 27. When the mounting plate 11 is lifted upward, the two support rods 26 can be pulled out of the receiving groove 27 under the action of gravity to support the mounting plate 11.

[0044] The inner cavity of the cable connection protection box 1 is symmetrically provided with insertion grooves 33, and U-shaped seats 28 are fixedly installed on both sides of the mounting plate 11. Tension springs 29 are fixedly installed on the inner sides of the two U-shaped seats 28. One end of the tension spring 29 is fixedly connected to an insertion rod 30 that passes through the U-shaped seat 28. One end of the insertion rod 30 passes through the U-shaped seat 28 and is inserted into the insertion groove 33. The end of the insertion rod 30 enters the insertion groove 33 to fix the mounting plate 11. Conversely, the end of the insertion rod 30 is pulled out of the insertion groove 33, and the mounting plate 11 can be moved up and down.

[0045] The guide grooves 10 are symmetrically arranged in the inner cavity of the cable power connection protection box 1, and guide sliders 15 slidably connected to the guide grooves 10 are fixedly installed at both ends of the mounting plate 11, and rolling grooves 31 are arranged on the inner wall of the guide grooves 10, and balls 32 are arranged in the rolling grooves 31. Both sides of the guide slider 15 are in contact with the balls 32, and the mounting plate 11 and the cable power connection protection box 1 are movably connected by the guide sliders 15, the guide grooves 10, the balls 32 and the rolling grooves 31. By pulling the insertion rod 30, the tension spring 29 is stretched, so that one end of the insertion rod 30 is separated from the inside of the insertion groove 33, so that the cable power connection structure can be moved upward, and at the same time, under the action of gravity, the support rod 26 is rotated to a vertical state, so that the cable power connection structure moved up to a certain height is supported and fixed. Compared with the operation in the narrow space of the cable power connection protection box 1, the cable power connection structure exposed on the top of the cable power connection protection box 1 is easier to perform cable power connection operation, thereby improving the cable power connection efficiency.

[0046] When the device of this embodiment is in use, first, the two cables are passed through the first cable tube 12 and the second cable tube 36 respectively into the interior of the cable power connection protection box 1, and the cables are successively passed through the gap between the short winding column 4 and the fixing plate 5, and the gap between the short winding column 4 and the long winding column 3, and then the retaining rod 19 is inserted into the interior of the notch 20. Under the elastic deformation capacity of the torsion spring 17, one end of the limiter 16 limits the position of the retaining rod 19 to prevent the cable from escaping from the gap between the short winding column 4 and the fixing plate 5, and then the insertion rod 30 is pulled to stretch the tension spring 29, so that one end of the insertion rod 30 is disengaged from the interior of the insertion groove 33, and then the cable power connection structure is moved up, and the guide slider 15 connected to the mounting plate 11 slides inside the guide slide groove 10, and at the same time, the ball 32 rolls inside the rolling groove 31 to prevent the guide slider 15 from generating a force between the cable power connection protection box 1 Friction is generated. When the cable power connection structure moves to the highest position, under the action of gravity, the support rod 26 rotates to a vertical state to support and fix the cable power connection structure that has moved up a certain height. Then, the conductor connection end of the cable is inserted into the interior of the arc groove 25, and the fastening bolt 21 is tightened to drive the protrusion 35 of the lower pressing block 24 rotatably connected thereto to be clamped into the interior of the groove 34, so that the conductors of the two cables are fixed on the conductive seat 23 to complete the wiring. Then, the support rod 26 is rotated to the interior of the accommodating groove 27, and the cable power connection structure is moved down to the bottom of the inner cavity of the cable power connection protection box 1, and the above-mentioned means are used again to fix the position of the cable power connection structure. Finally, the power connection box cover 9 is covered on the cable power connection protection box 1, and the rubber sealing ring 8 is clamped into the interior of the sealing groove 6. At the same time, the buckle head 7 and the buckle seat 2 are used to connect and fix the power connection box cover 9 and the cable power connection protection box 1.
