[0028] Example 1

[0029] like Figure 1-Figure 5 As shown, this embodiment proposes a protective shed that is easy to disassemble, including two bottom plates 1 and a plurality of square plates 7. The top of the bottom plate 1 is fixedly connected to two support columns 2 by bolts. A lifting column 3 is slidably mounted on the support column 2. A mounting frame 4 is welded to the top of every two lifting columns 3. A stabilizing device 5 is commonly provided on the support column 2 and the bottom plate 1. The stabilizing device 5 includes a driving shaft 51, which is rotatably mounted inside the support column 2. A driven shaft 55 is rotatably mounted inside the support column 2. A sliding rod 58 is slidably mounted inside the support column 2 and the bottom plate 1. A support plate 59 is welded to the bottom of the sliding rod 58. A universal wheel 500 is mounted to the bottom of the support plate 59. A lifting screw 50 and a support screw 57 are rotatably mounted inside the support column 2, respectively. The lifting column 3 is threadedly sleeved on the outer circumferential surface of the lifting screw 50. The sliding rod 58 is threadedly sleeved on the outer circumference of the supporting screw 57, and the outer circumferences of the lifting screw 50 and the supporting screw 57 are respectively fixedly sleeved with a small bevel gear 53 and a large bevel gear 56, and the outer circumferences of the driving shaft 51 and the driven shaft 55 are fixedly sleeved with a transmission bevel gear 52, and the outer circumferences of the driving shaft 51 and the driven shaft 55 are jointly installed with a synchronous belt 54, one side of the supporting column 2 is fixedly connected with a protective shell 502 by screws, and a turntable 501 is welded to one end of the driving shaft 51. Through the arrangement of the lifting column 3, the sliding rod 58 and other structures, the extension and retraction of the lifting column 3 drives the movement of the sliding rod 58, thereby realizing the rising of the mounting frame 4 and the contraction of the universal wheel 500. The rising of the mounting frame 4 realizes the use of the protective shed, and the contraction of the universal wheel 500 makes the base plate 1 supported on the ground, making the device more stable, thereby making the device more practical.

[0030] like Figure 1-Figure 3 As shown, a lifting slot is provided on the support column 2, and a part of the lifting column 3 is slidably connected inside the lifting slot.

[0031] like Figure 1-Figure 3 As shown, a placement groove 503 is formed on the support column 2 and the bottom plate 1 , and the sliding rod 58 is slidably connected inside the placement groove 503 .

[0032] like Figure 3-Figure 4 As shown, a lifting thread groove is provided on the lifting column 3, and the lifting screw 50 is threadedly connected inside the lifting thread groove.

[0033] like Figure 3-Figure 4 As shown, a supporting thread groove is formed on the sliding rod 58, and the supporting screw rod 57 is threadedly connected inside the supporting thread groove.

[0034] like Figure 3-Figure 4 As shown, the large bevel gear 56 is meshed with one of the transmission bevel gears 52 , and the small bevel gear 53 is meshed with the other transmission bevel gear 52 .

[0035] like Figure 3-Figure 4 As shown, a first reduction synchronous wheel and a second reduction synchronous wheel are fixedly sleeved on the outer circumferences of the driving shaft 51 and the driven shaft 55, respectively, and a synchronous belt 54 is installed on the outer circumferences of the first reduction synchronous wheel and the second reduction synchronous wheel.

[0036] The specific implementation principle of this embodiment is as follows: rotating the turntable 501 drives the driving shaft 51 to rotate, and the driving shaft 51 realizes the rotation of the driven shaft 55 through the synchronous belt 54, thereby realizing the rotation of the two transmission bevel gears 52, and the large bevel gear 56 and the small bevel gear 53 are meshed with the two transmission bevel gears 52 and the setting of different numbers of teeth, so that the lifting screw 50 and the support screw 57 are rotated and the rotation speed of the lifting screw 50 is greater than the rotation speed of the support screw 57, and the setting of the threads on the support screw 57 and the lifting screw 50 makes the lifting column 3 move while the sliding rod 58 moves at a slower speed, so that the lifting column 3 rises and drives the sliding rod 58 to rise synchronously, so that the protective shed is raised for use while the universal wheel 500 is retracted, so that the protective shed can be used more stably, and then the installation and fixation of the base plate 1 is realized by bolts. In the same way as the above steps, the lifting column 3 descends and drives the universal wheel 500 to move out, which facilitates the movement of the protective shed (the lifting slot and the placement slot 503 are both square, so that the sliding rod 58 and the lifting column 3 move vertically up and down).

[0037] Example 2

[0038] like Figure 1-Figure 5 As shown, the present embodiment also introduces a protective shed that is easy to disassemble, which adds the following structure on the basis of the first embodiment: a mounting dovetail mortise 8 is installed on one side of the mounting frame 4, a mounting dovetail groove is opened on the mounting frame 4, a connecting dovetail groove 10 is opened on one side of the square plate 7, a connecting dovetail mortise 9 is installed on the other side of the square plate 7, and a rubber pad 6 is fixedly connected to the bottom of the base plate 1. By setting structures such as the connecting dovetail groove 10 and the connecting dovetail mortise 9, and by the mortise and tenon structure of the connecting dovetail mortise 9 and the connecting dovetail groove 10, the installation between multiple square plates 7 is made more convenient and stable, and the installation of multiple groups of square plates 7 on the protective shed is achieved in the same way. The structure is simple and the square plates 7 can be disassembled and assembled.

[0039] The specific implementation principle of this embodiment is as follows: the installation of the first square plate 7 is achieved through the installation dovetail groove on the mounting frame 4 and the connecting dovetail mortise 9 on the square plate 7, the connection of multiple groups of square plates 7 is achieved through the connecting dovetail groove 10 and the connecting dovetail groove 10, and the installation and fixation of the tail square plate 7 is achieved through the connecting dovetail groove 10 and the installation dovetail mortise 8, thereby realizing the installation and fixation of multiple groups of square plates 7 and the mounting frame 4, with a simple structure and convenient operation.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
