[0002] Protection cabins can be divided into indoor protection cabins and outdoor protection cabins. The common feature of the two is that they are attached to existing buildings, have strong decorative properties, and can adopt more free modeling techniques. However, due to the different environments in which the two are located, there are also different design requirements. Because they are less restricted by the site environment and can be customized and placed according to the terrain, they can be moved at any time at low cost, so they are widely installed in crowded areas such as commercial streets, stations, squares and campuses.

[0003] A Chinese utility model with authorization announcement number CN218493223U discloses a telescopic protection cabin frame. When the device is in use, the height of the protection cabin frame is raised or lowered by fixing it with a first fastening nut, thereby adjusting the height of the protection cabin. However, during actual use, the device has certain defects. After multiple adjustments, the fastening nut is prone to loosening due to uneven force or external environmental influences, resulting in the height of the protection cabin frame being unable to be stably maintained. Therefore, it is necessary to redesign a telescopic mechanism of the protection cabin to address the above-mentioned problem. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A telescopic mechanism of a protective cabin comprises two groups of load-bearing tubes 1 and one group of force-bearing tubes 3. The upper ends of the two groups of load-bearing tubes 1 are both open, and an extension tube 2 is slidably connected thereto. The side wall of one group of extension tubes 2 is fixedly connected to the force-bearing tube 3. A lifting tube 4 is slidably connected inside the force-bearing tube 3 and extends to the outside to be fixedly connected to the extension tube 2. Slide grooves 7 are provided on the outer walls of the two groups of load-bearing tubes 1 and the force-bearing tubes 3. A fastening screw 6 is slidably installed in the slide groove 7. The side walls of the two groups of load-bearing tubes 1 and the upper end surfaces of the load-bearing tubes 1 are respectively fixedly connected to side plates 8 and fixing plates 9. The side plates 8 and fixing plates 9 are connected to the limiting plates 5 through a connecting mechanism. The limiting plates 5 are in close contact with the outer walls of the fastening screws 6 through an elastic mechanism.

[0021] By adjusting the height of the extension tube 2 and the position of the lifting tube 4, the height and length of the entire frame can be expanded or contracted. At the same time, the fastening screws 6 are provided to fix and limit the positions of the adjusted extension tube 2 and the lifting tube 4. It should be noted that the design of the fastening screws 6 is consistent with the structure of the fastening screws 6 in the comparative documents in the background technology, and is assumed to be based on public technology.

[0022] The connecting mechanism includes a connecting rod 10 slidably connected to the outer wall of the side plate 8 and the fixed plate 9, the end of the connecting rod 10 is fixedly connected to the limit plate 5, the elastic mechanism includes a limit block 11 fixedly connected to the end of the connecting rod 10, and the outer wall of the connecting rod 10 is sleeved with a spring 12, one end of the spring 12 is fixedly connected to the limit block 11, and the other end of the spring 12 is fixedly connected to the outer wall of the side plate 8;

[0023] This design provides a continuous pressure through the elastic mechanism, so that the limit plate 5 can fit tightly against the fastening screw 6, thereby ensuring the fastening and stability of the overall structure during the telescopic process and avoiding the problem of the fastening screw 6 loosening.

[0024] The radius of the limit block 11 is larger than the radius of the connecting rod 10. The outer wall of the limit plate 5 is penetrated by multiple groups of through holes, and the radius of the multiple groups of through holes is smaller than the diameter of the fastening screw 6. The diameter of the limit plate 5 is larger than the diameter of the slide groove 7, and the outer wall of the connecting rod 10 is L-shaped.

[0025] In the utility model, the specific function of the device is: the telescopic mechanism of the protective cabin is reasonably designed to realize convenient adjustment of the overall height and length of the protective cabin. First, the upper ends of the two groups of load-bearing tubes 1 are open, and the extension tubes 2 can slide therein. By adjusting the depth of the extension tubes 2 inserted into the load-bearing tubes 1 and the sliding distance of the lifting tubes 4 inside the force-bearing tubes 3, the height and width of the protective cabin can be adjusted.

[0026] In order to ensure the stability of the adjusted height and length, the adjusted extension tube 2 and pulling tube 4 can be fixed in a predetermined position by tightening the fastening screw 6 to prevent them from sliding. The spring 12 uses continuous elastic pressure to enable the limit plate 5 to fit tightly with the fastening screw 6, thereby ensuring the tightness and stability of the structure of the protective cabin during the telescopic adjustment process and avoiding the problem of loosening of the fastening screw 6.

[0027] In summary, the height and length of the protective cabin can be adjusted by adjusting the height of the extension tube 2 and the position of the lifting tube 4, and the fastening screws 6 in the slide groove 7 can be used to limit and fix the cabin. The connecting mechanism and the elastic mechanism further ensure the tightness and stability of the overall structure, avoiding the common loosening problem.
