[0029] 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.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a deep foundation pit assembled reinforced concrete support, including a support plate 1, a block 2 is fixedly connected to one side of the support plate 1, a slide groove 3 is provided inside the support plate 1, a slot 2 is provided inside the support plate 1, a slot 4 is provided inside the block 2, a locking groove 6 is provided inside the block 2, a positioning groove 7 is provided inside the block 2, a connecting block 8 is provided inside the support plate 1, a sleeve 9 is fixedly connected to one side of the connecting block 8, one end of the sleeve 9 is fixedly connected to a limiting plate 10, a rotating shaft 12 is rotatably connected inside the sleeve 9, and one end of the rotating shaft 12 is fixedly connected to The knob 11 and the other end of the rotating shaft 12 are fixedly connected with a connecting disk 13, and a connecting rod 14 is rotatably connected inside the connecting disk 13. One end of the connecting rod 14 is rotatably connected with a supporting column 16, and one end of the supporting column 16 is fixedly connected with a limiting block 17, and one side of the limiting block 17 is fixedly connected with a locking block 19. The outer wall of the connecting block 8 is provided with a positioning assembly, and the positioning assembly includes a positioning block 20, one side of the positioning block 20 is fixedly connected to the outer wall of the connecting block 8, and the outer wall of the positioning block 20 is slidably connected to the inside of the positioning groove 7, the outer wall of the locking block 19 is embedded in the locking groove 6, and the outer wall of the limiting block 17 is slidably connected to the inside of the connecting block 8;

[0031] Specifically, when performing the connection operation of the support plate 1, it is first necessary to insert the block 2 on one support plate 1 into the slide groove 3 on the other support plate 1. This process seems simple, but it is actually crucial because it establishes the initial connection between the two support plates 1. Then, by turning the knob 11, we can drive the shaft 12 to rotate. The rotation of the shaft 12 will further drive the connection plate 13 to rotate. The rotation of the connection plate 13 means that the movement of the support column 16 begins. The connection plate 13 drives the support column 16 to retract into the connection block 8 through the connecting rod 14. In this process, the contraction of the support column 16 is crucial because it will provide a basis for subsequent locking. Then, the support column 16 is retracted into the connection block 8 through the locking block 19. After completing the above steps, we need to insert the connection block 8 into the slot 1 4 through the slot 2 5. This step is to ensure that the position of the connection block 8 is accurate. The connection block 8 is positioned in the positioning groove 7 by the positioning block 20, which ensures the stability and accuracy of the connection block 8 in the support system. Finally, the locking block 19 needs to be inserted into the locking groove 6 for locking. This step means that the connection of the entire support system has been completed. At this time, the connection between the support plate 1 and the connecting block 8 will be very stable, ensuring the firmness of the entire structure.

[0032] Reference Figure 3 and Figure 4, a partition 15 is fixedly connected inside the connecting block 8, the outer wall of the support column 16 is slidably connected inside the partition 15, a spring 18 is sleeved on the outer wall of the support column 16, one end of the spring 18 is fixedly connected to the other side of the limit block 17, and the other end of the spring 18 is fixedly connected to one side of the partition 15, one side of the positioning block 20 is symmetrically arranged and fixedly connected to the outer wall of the connecting block 8, one side of the limit plate 10 is attached to one side of the support plate 1, and the outer wall of the connecting block 8 is slidably connected to the inside of the slot 4;

[0033] Specifically, when the rotating shaft 12 is released, the force of the spring 18 will take effect, pushing the limit block 17, thereby driving the locking block 19 to extend. In this process, the connecting block 8 plays a connecting role. Under normal use, the locking block 19 will be tightly embedded in the interior of the connecting block 8 to ensure the stability and safety of the entire device. However, when the equipment needs to be disassembled or repaired, it is only necessary to turn the knob 11 again to retract the locking block 19 into the interior of the connecting block 8. This design makes the disassembly of the connecting block 8 extremely simple and greatly improves work efficiency. Moreover, due to the contraction of the locking block 19, the connecting block 8 can be quickly separated from other components, so that the two support plates 1 can be easily separated.

[0034] Working principle: when using the deep foundation pit assembled reinforced concrete support, first insert the block 2 on one support plate 1 into the slide groove 3 on the other support plate 1 for connection, then turn the knob 11 to drive the rotating shaft 12 to rotate through the knob 11, the rotating shaft 12 drives the connecting plate 13 to rotate, the connecting plate 13 drives the supporting column 16 to retract into the connecting block 8 through the connecting rod 14, the supporting column 16 is retracted into the connecting block 8 through the locking block 19, then the connecting block 8 is inserted into the slot 1 4 through the slot 2 5, the connecting block 8 is positioned in the positioning groove 7 through the positioning block 20, and then the rotating shaft 12 is released. Under the tension of the spring 18, the limit block 17 is pushed to drive the locking block 19 to extend out of the connecting block 8 and reset, and then the locking block 19 is inserted into the locking groove 6 for locking, so that the two support plates 1 are connected through the cooperation of the connecting block 8 and the limit plate 10. When disassembly is required, only the knob 11 needs to be turned again to retract the locking block 19 into the connecting block 8, and the connecting block 8 can be quickly disassembled.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
