DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figure 1-7 The utility model provides a technical solution: a concrete canvas tent which is convenient for expanding space, comprising a fixing block 1, a supporting leg 2, a movable frame 3, a first spring 4, a pull rod 5, a connecting plate 6, a positioning protrusion 7, a fixing rod 8, an expansion component 9, an outer expansion plate 10, a fixing hole 11, a movable plate 12, a limiting block 13, a second spring 14, a fixing cap 15 and a concrete canvas cloth body 16.

[0033] When using this concrete canvas tent that is easy to expand, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the various components that make up the tent are moved to the corresponding use positions, the left and right ends of the fixed block 1 are hingedly connected with the support legs 2, and the middle part of the fixed block 1 is inserted with a movable frame 3, the movable frame 3 is fixedly connected to the pull rod 5, and the pull rod 5 is connected to the fixed block 1 by a slot, first, by pulling the pull rod 5 upward, the pull rod 5 drives the movable frame 3 and the fixed block 1 to slide, at this time, the movable frame 3 squeezes the first spring 4, so that the first spring 4 undergoes elastic deformation, and the left and right sides of the upper end of the movable frame 3 are fixedly connected with connecting plates 6, the movable frame 3 drives the connecting plate 6 to move upward and disengage from the upper end of the support leg 2, thereby releasing the limit between the support leg 2 and the fixed block 1, and then by flipping the support leg 2, the support leg 2 and the fixed block 1 are rotated, so that the support leg 2 is set tilted, when the support leg 2 and the fixed block 1 are rotated to as shown in the figure Figure 1In the state shown, by loosening the pull rod 5, the first spring 4 restores its elastic deformation, driving the movable frame 3 and the fixed block 1 to slide, so that the movable frame 3 drives the connecting plate 6 to engage with the corresponding position of the upper end of the supporting leg 2, thereby facilitating the position limiting between the supporting leg 2 and the fixed block 1;

[0034] like Figure 5 , Figure 6 and Figure 7 As shown, the expansion assembly 9 includes an external expansion plate 10 for connection, fixing holes 11 equidistantly arranged at the upper end of the external expansion plate 10, a movable plate 12 plugged into the middle of the external expansion plate 10, and a limiting block 13 for limiting. The left and right sides of the fixing block 1 close to one end of the external expansion plate 10 are fixedly connected with positioning protrusions 7, and the fixing rod 8 is fixedly connected to the fixing block 1. The positioning protrusions 7 are plugged into the left and right sides of the external expansion plate 10, and the fixing rod 8 is plugged into the middle of the external expansion plate 10. Then, the fixing cap 15 threadedly connected to the outer surface of the fixing rod 8 is rotated, so that the fixing cap 15 and the external expansion plate 10 are fitted, so as to facilitate the fixing between the external expansion plate 10 and the fixing block 1, and facilitate assembly.

[0035] After the connection between the external expansion plate 10 and the fixed block 1 is completed, Figure 1 and Figure 6 As shown, a fixing hole 11 is installed through the middle of the external expansion plate 10. According to the actual use requirements of the tent space, the limiting block 13 can be pressed downward to slide between the limiting block 13 and the movable plate 12, and a second spring 14 is arranged between the limiting block 13 and the movable plate 12. At this time, the limiting block 13 squeezes the second spring 14, so that the second spring 14 is elastically deformed, and the movable plate 12 moves out of the fixing hole 11, thereby loosening the limit between the external expansion plate 10 and the movable plate 12, and then the external expansion plate 10 is pulled to slide between the external expansion plate 10 and the movable plate 12, so as to facilitate the fixing of the fixing blocks 1 at the front and rear ends. The spacing between the two can be adjusted to expand the use space of the tent, and fixing holes 11 are evenly spaced at the upper end of the external expansion plate 10. When the external expansion plate 10 and the movable plate 12 slide to the corresponding position, the second spring 14 restores its elastic deformation to push the limit block 13 and the movable plate 12 to slide, so that the limit block 13 is inserted into the fixing hole 11 at the corresponding position, which is convenient for limiting the external expansion plate 10 and the fixing hole 11, and then the concrete canvas cloth body 16 is installed on the outside of the support frame by fixing measures such as binding straps. The fixation between the concrete canvas cloth body 16 and the support frame is a mature technology and will not be elaborated.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
