Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figures 1-2 As shown, an adjustable installation structure for a lightweight portal steel frame includes a support column 1, a base 2, a lifting column 3, a first screw 4, a screw sleeve 7, a second screw 8, and a mounting plate 9. There are two support columns 1, arranged vertically, each with a base 2 fixedly connected to its bottom end. A first screw 4 is vertically installed inside each support column 1, with its bottom end fixedly connected to the base 2. A lifting column 3 is also installed inside each support column 1, slidingly engaging with it. The lifting column 3 has an internal thread that connects to the first screw 4. A first drive assembly is connected to the lifting column 3 to drive its rotation. A mounting plate 9 is rotatably connected near the top of the lifting column 3. Second screws 8 are fixedly installed on each mounting plate 9. The screw sleeve 7 has internal threads that connect to both second screws 8 to drive the two second screws 8 to synchronously extend and retract, adjusting their spacing. A telescopic structure is connected to the top of the lifting column 3, and a second drive assembly for driving the screw sleeve 7 to rotate is installed on the telescopic structure.

[0022] Specifically, the vertical state of the support column 1 enables the lifting column 3 to rise and fall vertically within its cavity. By driving the lifting column 3 to rotate, it spirals upward on the first screw 4. The mounting plate 9 is connected to the lifting column 3 through a bearing seat, so that the lifting column 3 can rotate while supporting the mounting plate 9. When the screw sleeve 7 is driven to rotate, the screw sleeve 7 is screwed to the second screw 8, which can adjust the distance between the second screw 8.

[0023] Furthermore, the first drive assembly includes a first support base 10, a first rotating shaft 11, a first worm gear 12, and a first worm wheel 13. The first support base 10 is fixedly connected to the telescopic structure. The first rotating shaft 11 is rotatably connected to the first support base 10. The first worm gear 12 is fixedly installed on the first rotating shaft 11. The first worm wheel 13, which meshes with the first worm gear 12, is installed on the lifting column 3.

[0024] Specifically, the first support seat 10 is used to support the rotation of the first rotating shaft 11. When the first rotating shaft 11 rotates, it drives the first worm gear 12 to rotate. The first worm gear 12 meshes with and drives the first worm wheel 13 to rotate, which in turn drives the lifting column 3 to rotate.

[0025] Further, the second driving assembly comprises a second support base 15, a second rotating shaft 16, a second worm 17, and a second worm wheel 18. The second support base 15 is fixedly connected with the telescopic structure. The second rotating shaft 16 is rotatably connected with the second support base 15. The second worm 17 is arranged on the second rotating shaft 16. The second worm wheel 18 is arranged on the screw sleeve 7 and engaged with the second worm 17.

[0026] Specifically, the second support base 15 supports the rotation of the second rotating shaft 16, so that the second worm 17 on the second rotating shaft 16 can engage and drive the second worm wheel 18 to rotate, thereby rotating the screw sleeve 7.

[0027] Further, the telescopic structure comprises two slide rods 5 and a slide sleeve 6. The two slide rods 5 are rotatably connected with the top ends of the two lifting columns 3, respectively. The slide sleeve 6 is sleeved with the two slide rods 5 and is in sliding cooperation with the two slide rods 5. The first support base 10 is fixedly connected with the slide rod 5. The second support base 15 is fixedly connected with the slide sleeve 6.

[0028] Specifically, when the screw sleeve 7 is rotated to adjust the distance between the second screw rods 8, the slide rod 5 can be telescoped in the cavity of the slide sleeve 6 to adjust the distance between the second screw rods 8.

[0029] Further, the top of the slide rod 5 and the top of the slide sleeve 6 are fixedly connected with a mounting seat 20 for mounting a support beam.

[0030] Further, the lifting column 3 is uniformly provided with a plurality of limiting grooves 21 along the length direction. The two lifting columns 3 are both provided with a limiting clamp 22 which can be mounted on the inner side of the limiting groove 21.

[0031] Specifically, the limiting clamp 22 is fixed in the limiting groove 21 near the top end of the support column 1 by a fastener, thereby increasing the stability of the lifting column 3 and preventing the lifting column 3 from falling.

[0032] Further, the two ends of the first rotating shaft 11 are fixedly connected with a first nut 14. The two ends of the second rotating shaft 16 are fixedly connected with a second nut 19, so as to be easily screwed by a wrench or the like.

[0033] In the structure, when the height of the portal steel frame needs to be adjusted, a wrench or other tools are used to rotate the first nut 14 to drive the first rotating shaft 11 to rotate, and then the first worm 12 rotates synchronously, and after the first worm 12 rotates, the first worm 12 meshes to drive the first worm wheel 13 to rotate, so that the lifting column 3 rotates, and the lifting column 3 can be raised and lowered on the first screw rod 4 to change the height through the internal thread screwed with the first screw rod 4, when the height is determined, the limiting clamp 22 is fixed in the limiting groove 21 on the inner side close to the top end of the support column 1 through the fastener, so as to increase the stability of the lifting column 3, when the width of the portal steel frame needs to be adjusted, the second nut 19 is rotated to drive the second rotating shaft 16 to rotate, and then the second worm 17 rotates synchronously, the second worm 17 meshes to drive the second worm wheel 18 to rotate, and then the screw sleeve 7 rotates, the screw sleeve 7 adjusts the width through the second screw rod 8, and the self-locking characteristics of the second worm 17 and the second worm wheel 18 can lock the width, so that the height and width of the portal steel frame are conveniently adjusted.

[0034] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
