When the adjusting structure provided by the invention is used, when the adjusting structure is installed, the bending angle of the hose 2 is required to be determined according to the design of an electric wire, the fastening nut 256 is rotated outwards to release the fixation of the rotating plate 252, the rotating plate 252 is respectively rotated around the pin shafts under the action of the first springs 257, the rotating plate 252 drives the first toothed ring 253 to rotate outwards to release the matching of the second toothed ring 254, the second rotating rod can be rotated, wherein the rotating plate 252 is provided with an angle dial for rotation reference, when the second rotating rod 251 is rotated to a proper angle, the fastening nut 256 is rotated reversely, the fastening nut 256 is rotated inwards to squeeze the rotating plate 252, the rotating plate 252 rotates inwards around the pin shafts, the first springs 257 shrink, the rotating plate 252 drives the first toothed ring 253 to rotate inwards, the first toothed ring 253 is matched with the second toothed ring 254, the angle of the hose 2 is adjusted through the adjusting structure, the angle of the electric wire passes through the hose 2, the angle of the second toothed ring 254 can be determined, the angle of the hose 2 is not only adjusted rapidly, but also the stability of the hose 2 is improved through the matching of the first toothed ring 253 with the second toothed ring 254;
The rubber rods 24 are uniformly arranged on the outer side of the hose 2 to protect the hose 2, so that the hose 2 is prevented from being damaged by external impact, the rubber rods 24 have certain elasticity and buffering property, and are convenient for adjustment and protection at different angles, and the rubber rods 24 and the hose 2 are protected by the aid of the rubber-made protective tube 22, so that the hose 2 is prevented from being damaged easily due to overlarge internal stress at the bending part, the protection performance of the hose 2 is poor, and the water infiltration in soil can be reduced, so that the hose 2 is corroded;
When the mounting seat 31 is mounted, the mounting seat 31 is sleeved on the screw rods 36, one screw rod 36 is driven, the screw rod 36 drives the connected rotating wheel 39 to rotate, the rotating wheel 39 drives the belt 38 to rotate, the belt 38 drives the rotating wheel 39 at the other end to rotate, the two screw rods 36 are driven by the rotating wheel 39 to rotate, the two screw rods 36 synchronously rotate, the stability and balance of the movement of the mounting seat 31 are improved, and the mounting seat 31 moves downwards until the mounting seat 31 is attached to the fixed seat 3 due to the threaded fit of the screw rods 36 and the mounting seat 31, and then the butterfly nut 37 is sleeved on the screw rod 36, so that the stability of the mounting seat 31 and the fixed seat 3 is kept;
When the sleeve 1 is impacted by external force, the external force damages the internal stress of the sleeve 1, the sleeve 1 is easy to break and damaged, the sleeve 1 presses the arc plate 32 through the cooperation of the limiting rod 33 and the second spring 35, the arc plate 32 moves in the groove through the limiting rod 33 when the external force is applied, and the buffering of the sleeve 1 is finished through the second spring 35, so that the sleeve 1 is prevented from being damaged suddenly by the external force;
When the electric wire passes through the sleeve 1 and the hose 2, the electric wire is worn by contact friction with the inner walls of the sleeve 1 and the hose 2, the diameter of the sleeve 1 is large, the electric wire is inconvenient to fix, the diameter of the sleeve 1 is small, and the electric wire is inconvenient to enter; when the electric wire passes through the gyro wheel 4, according to the diameter size difference of electric wire, extrude gyro wheel 4 outside, gyro wheel 4 drives mounting bracket 41 outside motion, and mounting bracket 41 drives connecting rod 44 outside motion, and third spring 43 is compressed, is applicable to the fixed to different diameter electric wires, and the electric wire passes through between gyro wheel 4 when carrying, reduces the frictional force between electric wire and sleeve pipe 1 and the hose 2 through gyro wheel 4.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
