[0025] like Figure 1 and Figure 2 As shown, a self-retracting and resetting lifting column includes a shell 1, a moving column 2 is slidably connected to the inner surface of the shell 1, a hydraulic drive component 3 is fixedly connected to the lower part of the inner surface of the shell 1, the middle part of the lower end of the moving column 2 is fixedly connected to the hydraulic drive component 3, a connecting line 4 is fixedly connected to the upper front end of the shell 1, a storage component 5 is fixedly connected to the front end of the shell 1, and a buffer component 6 is provided at the upper end of the shell 1.

[0026] During the implementation of this embodiment, the shell 1 and the mobile column 2 are buried inside the soil. The hydraulic cylinder and hydraulic motor in the hydraulic drive component 3 work together with the hydraulic pump, hydraulic valve and other devices to realize the transmission and control of power to lift and reset the mobile column 2. At the same time, during the transportation process, the connecting line 4 can be stored by the storage component 5, and the buffer component 6 can be filled as the mobile column 2 is raised and lowered, thereby protecting pedestrians.

[0027] The hydraulic drive components 3 mentioned above are all mature technical means in the existing technology. In this solution, they can be used through hydraulic cylinders and hydraulic motors. These components work together with hydraulic pumps, hydraulic valves and other devices to achieve power transmission and control. Their internal structure and principles are not described in detail.

[0028] Specifically, in order to store the connecting wire 4, refer to Figure 4 and Figure 5 In this embodiment, the rear portion of the inner surface of the concave groove block 51 is fixedly connected with round rods 511 symmetrically up and down, and the front portion of the outer surface of the two round rods 511 is fixedly connected with circular ring blocks 512.

[0029] For further information, see Figure 4 and Figure 5 In this embodiment, the storage component 5 includes a concave groove block 51 fixedly connected to the front end of the shell 1, and a slide groove 53 is provided at the lower part of the inner surface of the concave groove block 51. The inner surface of the slide groove 53 is symmetrically slidably connected with a slider 55. A circular hole 52 is provided at the lower part of the right end of the concave groove block 51 and is connected to the inner surface of the slide groove 53. A threaded rod 54 is rotatably connected to the inner surface of the circular hole 52. The outer surface of the threaded rod 54 is threadedly connected to the slider 55. The threads on the outer surface of the threaded rod 54 are distributed at equal distances in opposite directions. The upper ends of the two sliders 55 are fixedly connected to a clamping plate 56, and the right end of the threaded rod 54 is fixedly connected to an operating block 58.

[0030] For further information, see Figure 4 and Figure 5 In this embodiment, the ends of the two clamping plates 56 that are close to each other are fixedly connected with a plurality of anti-slip strips 57, and the plurality of anti-slip strips 57 are linearly and equidistantly distributed.

[0031] During implementation, the connecting wire 4 to be stored is placed inside through the groove on the concave groove block 51, and the connecting wire 4 is wound around the round rod 511. At this time, the operating block 58 is rotated so that the operating block 58 drives the threaded rod 54 to rotate. Since the threaded rod 54 and the slider 55 are threadedly connected, and the thread grooves on the outer surface of the threaded rod 54 are symmetrically distributed in opposite directions, the rotation of the threaded rod 54 will drive the clamping plate 56 to move closer to the middle, so that the clamping plate 56 can fix the connecting wire 4 wound on the round rod 511, thereby effectively preventing the connecting wire 4 from scattering, and at the same time storing the connecting wire 4.

[0032] For further information, see Figure 4 and Figure 5 In this embodiment, a circular groove 59 is opened on the left part of the inner surface of the slide groove 53, and a round block 510 is rotatably connected to the inner surface of the circular groove 59. The right end of the round block 510 is fixedly connected to the left end of the threaded rod 54.

[0033] As can be seen from the above, during the rotation of the threaded rod 54 , the round block 510 rotates on the inner surface of the circular groove 59 , so that the threaded rod 54 will not deviate from the rotation position during rotation, thereby improving the rotation stability of the threaded rod 54 .

[0034] Example 2

[0035] This embodiment adds a buffer component 6 that can buffer the moving column 2 on the basis of the first embodiment, so as to achieve the purpose of buffering and protecting pedestrians when the moving column 2 is hit.

[0036] Specifically, in order to provide buffer protection for pedestrians who are hit by the moving column 2, refer to Figure 3 、 Figure 6 and Figure 7 In this embodiment, the buffer assembly 6 includes an airbag 66, and rectangular grooves 61 are provided on the left and right parts of the inner surface of the shell 1. The inner surfaces of the two rectangular grooves 61 are provided with stamping grooves 62, and the inner surfaces of the two stamping grooves 62 are slidably connected with pistons 64. The upper end of the shell 1 is provided with a circular groove 63 connected to the inner surface of the stamping groove 62, and the lower part of the inner surface of the circular groove 63 is fixedly connected to the lower end of the airbag 66, and the inner surface of the circular groove 63 is connected to the inner cavity of the airbag 66.

[0037] For further information, see Figure 3 、 Figure 6 and Figure 7 In this embodiment, the middle part of the lower end of the two pistons 64 is fixedly connected with a connecting rod 65, and the ends of the two connecting rods 65 away from the pistons 64 are fixedly connected to the lower end of the movable column 2, and the outer surfaces of the two connecting rods 65 are slidably connected to the inner surface of the rectangular groove 61.

[0038] During the implementation process, as the moving column 2 rises, the moving column 2 drives the connecting rod 65 to move downward, and then drives the inner surface of the outer stamping groove 62 of the piston 64 on the connecting rod 65 to slide, so that the piston 64 squeezes the air inside the stamping groove 62, allowing the air to enter the airbag 66 through the annular groove 63, so that the airbag 66 is filled. At the same time, the airbag 66 wraps up the moving column 2 to prevent pedestrians from being injured by accidentally colliding with the moving column 2.

[0039] Secondly, during the process of the moving column 2 descending, the piston 64 is driven to move downward. At this time, the piston 64 extracts the air in the airbag 66 into the inside of the stamping groove 62, and at the same time, the airbag 66 is retracted into the inside of the annular groove 63.

[0040] For further information, see Figure 3 、 Figure 6 and Figure 7 In this embodiment, the middle parts of the inner surfaces of the two stamping grooves 62 are fixedly connected to the limiting blocks 67 , and the inner surface diameters of the two limiting blocks 67 are larger than the outer surface diameter of the connecting rod 65 .

[0041] During the implementation process, since the piston 64 slides on the inner surface of the stamping groove 62, the limit block 67 provided can effectively prevent the piston 64 from contacting the rectangular groove 61 during movement, thereby preventing the piston 64 from being unable to perform normal extrusion operations.

[0042] Working process: During transportation, the connecting wire 4 to be stored is placed into the concave groove block 51 and wrapped around the round rod 511. At this time, the operating block 58 is rotated so that the operating block 58 drives the threaded rod 54 to rotate, so that the sliders 55 on the threaded rod 54 move toward the middle, so that the clamping plate 56 on the slider 55 fixes the connecting wire 4 wrapped around the round rod 511 to prevent the connecting wire 4 from falling off. At the same time, when the moving column 2 is raised, the piston 64 on the connecting rod 65 is driven to slide on the inner wall of the stamping groove 62, squeezing the internal air into the airbag 66, so that the airbag 66 wraps the moving column 2.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
