Although they can ensure stability during use, they are extremely inconvenient in use, disassembly, transportation, etc., and the height is fixed and cannot be adjusted according to actual needs. In addition, there are some improvements to the structure of the scaffold, but most of them are driven by connecting rods to present different heights, but the stability during use cannot be guaranteed, which poses a safety hazard.

[0004] To sum up, the above technical problems need to be solved. Utility Model Content

DETAILED DESCRIPTION

[0019] 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.

[0020] The utility model provides Figure 1-4 The anti-loosening quick-disassembly scaffold shown in the figure comprises a main board 1, a support rod 2 is arranged on the outer wall of the lower side of the main board 1, and the support rod 2 comprises a base rod 3, an extension rod 4 and an inner rod 5, the base rod 3 is rotatably mounted on the outer wall of the lower side of the main board 1, the extension rod 4 is movably connected with the base rod 3, and the inner rod 5 is movably mounted on the extension rod 4; an extension screw 10 is arranged on the base rod 3, and a mounting block 8 is arranged on the outer wall of the lower side of the main board 1, a mounting hole 9 is opened on the mounting block 8, a fixing nut 11 is arranged in the mounting hole 9, a polygonal opening 12 is arranged on the mounting hole 9, and a slider 13 matching the polygonal opening 12 is arranged on the fixing nut 11. The support rods 2 are distributed on the outer wall of the lower side of the main board 1 in a rectangular array. When in use, first rotate the support rods 2 to a state perpendicular to the main board 1, and fix them with the fixing nut 11 and the extension screw 10. In order to ensure that the support rod 2 always maintains a vertical and non-loose connection with the main board 1 during use, the slider 13 can be slid into the polygonal opening 12 after the fixing nut 11 is fully installed. Through the effect of the polygon, the support rod 2 is always in a stable state to ensure the safety of the user. In addition, the height of the main board 1 from the ground can be adjusted according to actual use needs, that is: by adjusting the connection relationship between the base rod 3, the extension rod and the inner rod 5, the support rod 2 has three heights for easy use.

[0021] Specifically, the base rod 3 is provided with a mounting groove 1 6, the extension rod 4 is provided with a connecting rod 41, the connecting rod 41 is slidably installed in the mounting groove 1 6, the outer wall of the lower side of the extension rod 4 is provided with a mounting groove 2 7, and the inner rod 5 is slidably installed in the mounting groove 2 7. The inner walls of the mounting groove 1 6 and the mounting groove 2 7 near one end of the port are provided with a threaded opening 16, and the connecting rod 41 and the inner rod 5 are respectively provided with thread lines matching the threaded opening 16. When in use, threads are provided at both ends of the connecting rod and the inner rod 5. The connecting rod can be fixed in cooperation with the threads through a threaded opening 16 located at the end of the mounting groove 1 6 to control the state of the connecting rod 41 being retracted or extended to the outside of the mounting groove. Similarly, the inner rod 5 can also be retracted inside the mounting groove 2 7 or fixed outside the mounting groove 2 7 through a threaded opening 16 provided at the end of the mounting groove 2 7. In this way, the length of the support rod 2 can be adjusted. The support rod body is composed of a base rod 3, an extension rod 4 and an inner rod 5. Therefore, the support rod 2 has three usable heights. When performing operations at a high level, the height of the support rod 2 can be adjusted according to actual conditions.

[0022] Specifically, the extended screw rod 10 is rotatably installed in the installation hole 9, and the fixing nut 11 is threadedly connected to the extended screw rod 10. The slider 13 is slidably installed on the outer wall of the fixing nut 11, and its outer wall is movably connected to the inner wall of the polygonal opening 12. When fixing the support rod body, the fixing nut 11 can be loosened and the slider 13 can be slid away from the polygonal opening 12 to ensure that the support rod body is in an arbitrary rotation state. Then, the support rod body is rotated until the groove 14 cooperates with the mounting block 8 to keep the position of the support rod body perpendicular to the main board 1. At this time, the fixing nut 11 can be rotated and the fixing nut 11 and the extension bolt can be tightened. At this time, the slider 13 is slid into the polygonal opening 12 to ensure that the horizontal height of the main board 1 is stable during use. The outer wall of the fixing nut 11 needs to be a rectangular with edges to ensure that the slider 13 can always maintain a stable state after sliding to connect with the polygonal opening 12. The purpose of setting the polygonal opening 12 is to cooperate with the fixing nut 11 and the extension screw 10. After tightening, there may be a deviation in the installation angle between the slider 13 and the polygonal opening 12. The polygon with smaller angles of the outer walls on the adjacent two sides is set to reduce the difficulty of alignment when there is a deviation after tightening.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
