However, the high-voltage cable branch box is installed in the outside world, but the screw in the above patent is in direct contact with the outside world for a long time without protection, so that the screw is in contact with moisture or other substances in the outside air for a long time, so that the surface of the screw will rust or be covered with a layer of dust, so that the screw may not be rotated normally when the cable branch box shell is disassembled, thereby affecting the normal disassembly of the cable branch box shell. Therefore, the inventor provides a high-voltage cable branch box with a protective function to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown, a high-voltage cable branch box with a protective function includes a support frame 10, and protective plates 11 are fixedly connected to the left, right and rear sides of the top of the support frame 10. A high-voltage cable branch box body 20 is arranged on the top of the support frame 10, and connecting blocks 21 are fixedly connected to the left and right sides of the bottom of the high-voltage cable branch box body 20. The connecting blocks 21 are in contact with the top surface of the support frame 10, and a fixing box 30 for fixing the high-voltage cable branch box body 20 is arranged between the two connecting blocks 21, and the bottom of the fixing box 30 is fixedly connected to the top of the support frame 10.

[0022] Preferably, installing protective plates 11 on three sides of the high-voltage cable branch box body 20 can reduce the impact force of external objects on the high-voltage cable branch box body 20, and the outer shell of the high-voltage cable branch box body 20 is made of alloy material, which can effectively reduce the impact of the harsh external environment on the interior of the high-voltage cable branch box body 20, thereby achieving the protection effect of the high-voltage cable branch box body 20.

[0023] refer to Figure 2 , the left and right sides of the interior of the fixed box 30 are rotatably connected with a rotatable bidirectional threaded rod 31, and the left and right sides of the bidirectional threaded rod 31 are threadedly connected with a pair of mirror-symmetrical moving blocks 32, and the front and rear ends of the outer sides of the two moving blocks 32 are fixedly connected with plug blocks 33, and the connection between the plug blocks 33 and the surface of the fixed box 30 and the surface of the fixed box 30 are provided with matching movable grooves 34. When in use, the counterclockwise rotating bidirectional threaded rod 31 drives the two moving blocks 32 to move back to each other, and drives the plug blocks 33 to slide along the inside of the movable groove 34. When in use, the plug blocks 33 do not leave the movable groove 34, and the limit distance is that the outer end of the moving plug block 33 is flush with the outer surface of the movable groove 34. The inner ends of the two connecting blocks 21 are provided with a pair of grooves (not shown in the figure) adapted to the plug blocks 33. When in use, the moving plug blocks 33 are inserted into the grooves on the inner side of the corresponding connecting blocks 21 to achieve the limit fixation of the connecting blocks 21, thereby achieving the fixation of the high-voltage cable branch box body 20.

[0024] Specifically, refer to Figure 2 , the middle position of the bidirectional threaded rod 31 is fixedly connected with a driven bevel gear 35, the right side of the driven bevel gear 35 is vertically meshed with an active bevel gear 36, and the front side of the active bevel gear 36 is fixedly connected with a rotating rod 37, and the rotating rod 37 passes through the front of the fixed box 30 and is rotatably connected with the front of the fixed box 30. The front of the rotating rod 37 is fixedly connected with a turning handle 38. The turning handle 38 can facilitate the free rotation of the rotating rod 37. When in use, the turning handle 38 is turned counterclockwise, and the turning handle 38 drives the rotating rod 37 to rotate in the same direction. Through the cooperation of the active bevel gear 36 and the driven bevel gear 35, the bidirectional threaded rod 31 rotates counterclockwise, driving the plug blocks 33 on both sides to gradually plug into the groove body on the connecting block 21. Similarly, turning the turning handle 38 clockwise can drive the bidirectional threaded rod 31 to rotate in the same direction, driving the two plug blocks 33 to be disconnected from the connecting block 21. Thereby achieving the effect of convenient installation and disassembly of the high-voltage cable branch box body 20.

[0025] During the operation of the above device, since the handle 38 cannot be fixed, the handle 38 may rotate naturally clockwise to drive the bidirectional threaded rod 31 to rotate in the same direction, causing the plug block 33 to be disconnected from the connecting block 21, or the plug block 33 and the connecting block 21 to be loosely connected.

[0026] refer to Figure 3, 4 A ratchet 50 is fixedly connected to the rotating rod 37, and the ratchet 50 is located between the front of the fixed box 30 and the turning handle 38. A ratchet 54 is installed on the upper right end of the ratchet 50; a turning plate 51 is fixedly connected to the front of the fixed box 30, and a pair of clamping blocks 52 are fixedly connected to the left side of the turning plate 51. The opposite ends of the clamping blocks 52 are rotatably connected to the ratchet 54 through a movable shaft, and a support spring 55 is fixedly connected to the right side of the ratchet 54, and the right side of the support spring 55 is fixedly connected to the surface of the turning plate 51.

[0027] When the rotating rod 37 rotates counterclockwise, the ratchet 50 is driven to rotate in the same direction, and the teeth on the surface of the ratchet 50 contact the surface of the ratchet 54, driving the ratchet 54 to flip clockwise, and then the ratchet 54 is pulled back by the support spring 55 to flip counterclockwise, so that when the ratchet 50 rotates counterclockwise, the ratchet 54 performs the above-mentioned reciprocating operation, but when the ratchet 50 rotates clockwise, the ratchet 54 is stuck between two adjacent teeth on the surface of the ratchet 50, limiting the rotation of the ratchet 54, thereby limiting the rotation of the rotating rod 37. When the high-voltage cable branch box body 20 is disassembled and the rotating rod 37 needs to rotate clockwise, the ratchet 54 can be manually pulled out to separate the ratchet 54 from the surface of the ratchet 50, so that the rotating rod 37 can rotate clockwise.

[0028] During long-term use, if the rotating rod 37 is directly exposed to the air, it may be affected by the external environment, and a layer of dust may be adsorbed on the surface of the rotating rod 37, making it difficult to rotate the rotating rod 37, affecting the disassembly of the high-voltage cable branch box body 20. Therefore, a reversible protective cover 40 is provided on the outer periphery of the rotating rod 37 exposed outside the fixing box 30.

[0029] refer to Figure 4 A pair of positioning blocks 41 are fixedly connected to the top of the front side of the fixing box 30 , and a flip rod 42 is rotatably connected to the opposite sides of the two positioning blocks 41 , and a protective cover 40 is fixedly connected to the flip rod 42 .

[0030] Preferably, reference Figure 4 The front of the fixing box 30 is fixedly connected with a connecting strip 45, and a groove 46 is provided on the front of the connecting strip 45. The bottom of the protective cover 40 is fixedly connected with a protruding strip 44, and the protruding strip 44 is designed to be compatible with the groove 46 in an arc shape, and the protruding strip 44 is made of a sealing strip material. When in use, the protective cover 40 is turned downward and the protruding strip 44 is embedded in the groove 46. After the protruding strip 44 made of a sealing strip material is connected with the groove 46, the gap at the connection can be reduced, and then when the protective cover 40 is in use, the influence of the external environment on the inside of the protective cover 40 can be minimized. In this way, daily protection of the rotating rod 37 is achieved.

[0031] The working principle of the utility model is: the protective cover 40 is flipped downward, and the protruding strip 44 is embedded in the groove 46. After the protruding strip 44 made of sealing strip material is connected with the groove 46, the gap at the connection can be reduced. Therefore, when the protective cover 40 is used, the influence of the external environment on the inside of the protective cover 40 can be minimized, thereby achieving daily protection of the rotating rod 37.

[0032] When the high-voltage cable branch box body 20 needs to be fixed, the handle 38 is turned counterclockwise, and the handle 38 drives the rotating rod 37 to rotate in the same direction. The two-way threaded rod 31 rotates counterclockwise through the cooperation of the active bevel gear 36 and the driven bevel gear 35, driving the plug blocks 33 on both sides to gradually plug into the grooves on the connecting block 21. Similarly, turning the handle 38 clockwise can drive the two-way threaded rod 31 to rotate in the same direction, driving the two plug blocks 33 to be disconnected from the connecting block 21. Thus, the high-voltage cable branch box body 20 is easy to install and disassemble.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
