The implementation principle of the high-strength easy-to-operate roof swing type trailer roof provided by the embodiment of the application is as follows:

When the trailer is used for the first time, the trailer is fixed on the connecting block 6, the outer tube 4 is rotated, the base 1 is placed on the ground, meanwhile, the rotating rod 51 drives the sliding block 511 to slide in the sliding cavity 62, when the trailer top is to be placed perpendicular to the ground, the sliding block 511 presses the corresponding fixed shaft 72, the fixed shaft 72 slides along the depth direction of the sliding hole 71, the elastic piece 73, namely the compression spring, is pressed, the compression spring is stressed to shrink and keep the trend of resetting until the fixed shaft 72 is opposite to the fixed hole 74 on the sliding block 511, the compression spring resets and extends and applies thrust to the fixed shaft 72, the fixed shaft 72 is in plug-in fit with the fixed hole 74 on the sliding block 511, the sliding block 511 is limited to move in the sliding cavity 62, namely the connecting block 6 is fixedly connected with the fixed plate 5, and then the fixed nut 521 is screwed until the sliding block 511 is tightly abutted to the cavity bottom of the sliding cavity 62, and the fixing between the fixed plate 5 and the connecting block 6 is reinforced, namely the supporting and fixing of the trailer top corresponding to the trailer top are realized.

Then, a pulling force is applied to the lifting rod 321, so that the lifting rod 321 slides in a direction away from the inner tube 2, the cooperation between the lifting rod 321 and the locking hole 21 is canceled, the reset piece 91, namely the tension spring, is extruded, the tension spring is stressed to shrink and keep a reset trend, then an upward pulling force is applied to the inner shaft 8, namely the middle tube 3 and the outer tube 4 are lifted upwards at the same time, after the proper position is reached, the proper locking hole 21 is selected on the inner tube 2, the pulling force applied to the lifting rod 321 is canceled, the tension spring is reset to extend, and a pushing force is applied to the lifting rod 321, so that the lifting rod 321 moves in a direction close to the inner tube 2, the lifting rod 321 is in plug-in cooperation with the corresponding locking hole 21, namely the position relation between the inner tube 2 and the outer tube 4 is fixed, and coarse adjustment of lifting height of a trailer is realized.

The handle 10 is then turned to the proper direction of application, and the coupling nut 8211 is tightened, i.e., the handle 10 and the inner shaft 8 are fixedly coupled via the coupling sleeve 82. The pushing force is applied to the handle 10, the handle 10 drives the inner shaft 8 to rotate, the inner shaft 8 is in threaded connection with the rotating hole 311 on the fixing seat 31, so that the inner shaft 8 moves upwards, the outer tube 4 is driven by the inner shaft 8 to move upwards through the supporting plate 81, the outer tube 4 is lifted with the connecting block 6, namely, the trailer is lifted, and the accurate adjustment of the lifting height of the trailer is realized.

When the proper height is reached, the limiting shaft 431 is in threaded connection with the limiting hole 811, so that the rotation of the supporting plate 81 is limited, and the supporting plate 81 is axially and fixedly connected to the circumferential side wall of the inner shaft 8, so that the rotation of the inner shaft 8 is limited, and the handle 10 is prevented from driving the inner shaft 8 to rotate due to false touch.

When the use is completed, the fixing nut 521 is turned, and the sliding block 511 is canceled from tightly abutting against the bottom of the sliding chamber 62. And then the rotating shaft is rotated, the rotating shaft extrudes the fixed shaft 72 in the fixed hole 74, so that the fixed shaft 72 slides along the depth direction of the sliding hole 71, extrudes the compression spring, and the compression spring is stressed to shrink and keep the reset trend until the cooperation between the fixed shaft 72 and the fixed hole 74 is canceled, and the compression spring resets with the fixed shaft 72, so that the rotating rod 51 can slide in the sliding cavity 62 with the sliding block 511. When the trailer rotates to a proper position, the angle of the trailer roof is convenient for the trailer to carry, the corresponding fixed shaft 72 is in plug-in fit with the fixed hole 74 on the sliding block 511 through the compression spring, the trailer roof is fixed on the trailer under the condition that the use of the trailer is not affected, the carrying of the corresponding trailer roof is realized, and then the fixed nut 521 is screwed down for reinforcement and fixation. And when the trailer is used again, the fixing nut 521 is only required to be rotated and the rotating shaft is required to be rotated so that the top of the trailer reaches a proper position.

The trailer is carried on the trailer roof, so that the trailer roof is not required to be disassembled, and the trailer roof is not required to be installed again when being used again, so that the time for disassembling and assembling the trailer roof is saved.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
