[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figure 1 and Figure 2 , an embodiment provided by the present invention: A quick-disassembly and assembly type formwork support frame includes an outer frame 1, a base 2 is fixedly connected to the bottom side of the outer frame 1, a fixed sleeve 3 is fixedly connected to the top side of the outer frame 1, a friction ring 20 is fixedly connected inside the fixed sleeve 3, a telescopic frame 4 is slidably connected inside the friction ring 20, a fixed frame 5 is fixedly connected to the top side of the telescopic frame 4, a cross frame 6 is slidably connected inside the fixed frame 5, longitudinal limiting grooves 8 are respectively opened at the left and right ends of the front side of the cross frame 6, horizontal limiting grooves 7 are respectively opened at the left and right ends of the front side of the cross frame 6 and the fixed frame 5, a limiting block 11 is arranged inside the horizontal limiting groove 7, a groove is opened at the rear side of the horizontal limiting groove 7, a through groove is opened at the front side of the groove, the through groove is connected to the horizontal limiting groove 7 and the groove, a limiting post 10 is slidably connected inside the groove, a connecting rod 9 is fixedly connected to the front side of the limiting post 10, and the front side of the connecting rod 9 is fixedly connected to the rear side of the limiting block 11. The longitudinal limiting groove 8 is connected to the horizontal limiting groove 7, and the horizontal limiting groove 7 penetrates through the front outer wall of the fixed frame 5.

[0025] Specifically, during use, the cross frame 6 is placed into the fixed frame 5 from both sides. After being placed, the limiting block 11 inside the horizontal limiting groove 7 is pulled out, rotated by 90 degrees, and then pushed back into the longitudinal limiting groove 8. Since the rear side of the longitudinal limiting groove 8 is shorter than the horizontal limiting groove 7, the limiting block 11 will not completely enter the longitudinal limiting groove 8, resulting in a part of the front side of the limiting block 11 remaining in front of the cross frame 6, thereby clamping both sides of the fixed frame 5, and further fixing the cross frame 6, so that the formwork support frame can be quickly installed, improving the installation speed and work efficiency.

[0026] Refer to Figure 1 , Figure 3 and Figure 4, a notch is provided on the front side of the fixed sleeve 3. A friction ring 20 is fixedly connected inside the fixed sleeve 3. Elastic pieces 12 are fixedly connected to both the left and right ends of the front side of the fixed sleeve 3. Through grooves are provided inside the elastic pieces 12. A connecting column 17 is arranged inside the two through grooves. Connecting buckles 14 are fixedly connected to both the left and right ends of the connecting column 17. Rotating buckles 13 are arranged on the adjacent sides of the two connecting buckles 14. Limiting buckles 16 are fixedly connected to the separated sides of the two elastic pieces 12. Pressure-bearing blocks 19 are fixedly connected to the front ends of the separated sides of the two limiting buckles 16. Pressing blocks 18 are fixedly connected to the adjacent sides of the two rotating buckles 13. A handle 15 is fixedly connected to the front side of the two rotating buckles 13. The two rotating buckles 13 are rotatably connected to the outer wall of the connecting column 17.

[0027] Specifically, when the telescopic frame 4 is pulled upward to the required height, the handle 15 is pulled downward, which drives the rotating buckle 13 to rotate downward, aligning the pressing block with the pressure-bearing block 19 on the front side of the limiting buckle 16, so that the pressing block presses the pressure-bearing block 19, causing the two elastic pieces 12 to displace inward, shrinking the fixed sleeve 3, driving the internal friction ring 20 to shrink, and then generating a large frictional force on the internal telescopic frame 4 to prevent the telescopic frame 4 from slipping, completing the limiting of the telescopic frame 4. When disassembling, just operate the above steps in reverse, so that the height of the support frame can be freely selected, enhancing the versatility and adaptability of the support frame.

[0028] Working principle: During use, the cross frame 6 is placed inside the fixed frame 5 from both sides. After placement, the limiting block 11 inside the horizontal limiting groove 7 is pulled out, rotated 90 degrees, and then pushed back into the vertical limiting groove 8. Since the rear side of the vertical limiting groove 8 is shorter than the horizontal limiting groove 7, the limiting block 11 will not completely enter the vertical limiting groove 8, leaving a part of the front side of the limiting block 11 in front of the cross frame 6, thus clamping both sides of the fixed frame 5 and then fixing the cross frame 6. After the fixing is completed, the telescopic frame 4 is pulled upward to the required height, and then the handle 15 is pulled downward, which drives the rotating buckle 13 to rotate downward, aligning the pressing block with the pressure-bearing block 19 on the front side of the limiting buckle 16, so that the pressing block presses the pressure-bearing block 19, causing the two elastic pieces 12 to displace inward, shrinking the fixed sleeve 3, and the fixed sleeve 3 drives the internal friction ring 20 to shrink, and then generating a large frictional force on the internal telescopic frame 4 to complete the limiting of the telescopic frame 4. When disassembling, just operate the above steps in reverse.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
