[0019] 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.

[0020] See also Figures 1 to 3 In the embodiment of the utility model, an adjustable foundation pit enclosure includes a first mounting column 1 and a second mounting column 11, and winding rollers 5 are fixedly installed on the outer sides of the first mounting column 1 and the second mounting column 11. A plurality of guardrails 12 are wound around the outer side of the winding roller 5 on the first mounting column 1, and one end of the guardrail 12 is fixedly connected to the winding roller 5 on the second mounting column 11. The bottom ends of the first mounting column 1 and the second mounting column 11 are both provided with bottom plates 9, the first mounting column 1 is rotatably connected to the bottom plate 9, and the second mounting column 11 is fixedly connected to the bottom plate 9, an extrusion plate 3 is provided on one side of the first mounting column 1, and an insertion strip 2 is symmetrically fixedly installed on one side of the extrusion plate 3, and the two insertion strips 2 both penetrate the first mounting column 1, and a through groove 8 is opened inside the insertion strip 2, and a screw 13 is provided inside the through groove 8, and nuts 7 are threadedly connected to the outer side of the screw 13 and on both sides of the first mounting column 1, and the nuts 7 are tightly fitted with the first mounting column 1.

[0021] A warning strip 18 is disposed around the outer side of the first mounting column 1 and below the lowermost guardrail 12 , and the warning strip 18 has a reflective warning effect.

[0022] A fixing bolt 10 is provided on the top of the bottom plate 9, and the bottom plate 9 is fixed to the ground through the fixing bolt 10 for fixing the enclosure.

[0023] The guardrail 12 is a high-strength braided rope.

[0024] A slot 4 is symmetrically fixedly installed on one side of the extrusion plate 3, and a card slot 6 is provided on the top and bottom of the two slots 4. Two plug blocks 14 are symmetrically fixedly installed on one side of the winding roller 5 outside the second mounting column 11. The two plug blocks 14 are adapted to the slot 4. Both plug blocks 14 are provided with mounting grooves 15. A partition is fixedly installed inside the mounting groove 15, and a spring 16 is fixedly installed on the top and bottom of the partition. A card block 17 is fixedly installed on one end of the spring 16 and passes through the mounting groove 15, so that the two enclosures can be quickly connected.

[0025] The clamping block 17 is matched with the clamping slot 6 .

[0026] The working principle of the utility model is:

[0027] When the utility model is used, the first mounting column 1 is fixed to the ground by the fixing bolt 10, and the second mounting column 11 is pulled, and the second mounting column 11 drives the guardrail 12 and the warning strip 18 wound on the outside of the first mounting column 1 to be unwound, so that they can be stretched according to the required length. After the length is determined, the nut 7 is loosened so that the insert 2 can slide on the first mounting column 1. At this time, the extrusion plate 3 on one side of the sliding insert 2 is used to squeeze and limit the remaining part of the guardrail 12 and the warning strip 18 to prevent the guardrail 12 and the warning strip 18 from being scattered on the outside of the first mounting column 1. At this time, the single enclosure is set up. When rolling up, the first mounting column 11 rotatably connected to the bottom plate can be rotated to squeeze the guardrail 12 and the warning strip 18 Reel in and fix the second mounting column 11 to the ground with the fixing bolt 10, take out another enclosure body, and put the slot 4 on it on the outside of the plug block 14 of the previous enclosure body. In the process of the slot 4 being put on the outside of the plug block 14, the block 17 will be squeezed and contracted by the inner wall of the slot 4 inside the mounting slot 15, and the spring 16 will also be compressed at this time. When the block 17 moves to the slot 6, the spring 16 will reset, and the block 17 will be stuck into the inside of the slot 6 at this time, thereby completing the connection between the two enclosures. When the two enclosures need to be dismantled, remove the fixing bolts 10 of the other enclosure, press the two blocks 17, pull outward to remove the enclosure with the fixing bolts 10, and the two enclosures can be dismantled.
