In addition, specific terms can be selected by the applicant, and in this case, the detailed meanings thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as mere names, but based on the meanings of the terms and the overall description of the present application.

[0028] Referring to Figures 1-8 , the present embodiment provides a foundation pit full-coverage curtain support device of a unit, which includes a base column 1 and an adjusting column 2 slidingly disposed with the base column 1. As shown in Figure 1 , the base column 1 has an insertion slot 11 open at one end, the insertion slot 11 extending along the length direction of the base column 1, and one end of the adjusting column 2 inserted into the insertion slot 11, the other end of the adjusting column 2 being provided with a wire binding assembly 3 for connecting a connecting rope.

[0029] Specifically, as shown in Figure 5 , the wire binding assembly 3 includes a positioning shaft 31 and a winding roller 32 concentrically disposed with the positioning shaft 31 and movably sleeved on the positioning shaft 31. When binding, one end of the connecting rope can be wound on the winding roller 32, and then the protruding part of the connecting rope is knotted to complete the binding; when disassembling, the knot is untied, and since the winding roller 32 is coaxially rotated with the positioning shaft 31, after the knot is untied, only the end of the connecting rope connected with the curtain needs to be pulled to drive the winding roller 32 to rotate quickly in the circumferential direction to release the connecting rope wound on the winding roller 32.

[0030] Further, as shown in Figure 6 and Figure 7As shown, the end of the adjusting column 2 extending out of the slot 11 is provided with a receiving part 21, the receiving part 21 has a barrel cavity 211 with one end opening, the receiving part 21 can cover the winding roller 32, and then the winding roller 32 and the connecting rope wound on the winding roller 32 are received in the barrel cavity 211, so that the rope is prevented from being exposed to the outside, and the wear and corrosion caused by the external environment (rain, sand or ultraviolet environment, etc.) are reduced.

[0031] Further, as shown in Figure 6 and Figure 7 , the receiving part 21 also has a threaded groove 212 in communication with the barrel cavity 211 and concentrically arranged; the positioning shaft 31 has a locking rod 33 concentrically arranged at one end and extending in the axial direction, and the outer periphery of the locking rod 33 has external threads matched with the threaded groove 212; the other end of the positioning rod is provided with a twist cap 34. By arranging the twist cap 34, the knob positioning shaft 31 and the locking rod 33 are facilitated; by rotating the twist cap 34, the external threads on the outer periphery of the locking rod 33 are screwed with the threaded groove 212, so as to control the positioning rod to enter or exit the barrel cavity 211, that is, to control the winding roller 32 and the connecting rope wound on the winding roller 32 to enter or exit the barrel cavity 211.

[0032] Further, as shown in Figure 7 , the radial cross-sectional dimension of the twist cap 34 is greater than the opening cross-sectional dimension of the barrel cavity 211, so that when the locking rod 33 is completely screwed with the threaded groove 212, that is, when the winding roller 32 is completely received in the barrel cavity 211, the twist cap 34 can abut against the opening end of the receiving part 21, so as to close the opening of the barrel cavity 211, preventing rain, dust and the like from entering the barrel cavity 211 through the opening end of the receiving part 21.

[0033] In some embodiments, as shown in Figure 2 and Figure 7 , the side wall of the receiving part 21 is provided with a rope entering and exiting slot 213 in communication with the barrel cavity 211, and one end of the rope entering and exiting slot 213 extends to the opening of the barrel cavity 211; the rope entering and exiting slot 213 is used as a placement area for the extending part of the connecting rope

[0034] In some embodiments, as shown in Figure 1 , the utility model discloses a foundation pit full-covering awning support device of a unit further comprises a locking assembly 4 arranged at the opening of the slot 11 close to the base column 1, for fixing the adjusting column 2 after telescopic sliding.

[0035] Specifically, as shown in Figure 4 and Figure 8As shown, the base column 1 is provided with a sliding groove 12 perpendicular to and communicating with the insertion slot 11 near the opening of the insertion slot 11; the locking assembly 4 includes a limiting block 41 arranged in the sliding groove 12; the adjusting column 2 is provided with a limiting groove 22 arranged along the length direction on the side opposite to the sliding groove 12; one end of the limiting block 41 can extend out of the sliding groove 12 and be inserted into any limiting groove 22, and the other end of the limiting block 41 is provided with a first spring 42 between the opposite surface of the sliding groove 12.

[0036] Specifically, as shown in the drawings, Figure 6 the limiting groove 22 has a contact wall 221 arranged perpendicularly to the extension direction of the insertion slot 11 away from the insertion slot 11, and a sliding surface wall 222 arranged obliquely close to the insertion slot 11; the limiting block 41 has a pointed portion 411 consistent with the longitudinal section profile of the limiting groove 22; when the base column 1 and the adjusting column 2 are locked, the pointed portion 411 of the limiting block 41 is embedded in the limiting groove 22 opposite to the side wall of the adjusting column 2.

[0037] In summary, the base column 1 and the adjusting column 2 are slidingly matched to realize stepless height adjustment; by arranging the locking assembly 4, when the adjusting column 2 is slid outwardly to extend out of the insertion slot 11, the sliding surface wall 222 of the limiting groove 22 arranged obliquely is in contact with and pressed against the pointed portion 411 of the limiting block 41, which drives the limiting block 41 to move into the sliding groove 12 and press the first spring 42, that is, the locking assembly 4 does not limit the sliding extension of the adjusting column 2 out of the insertion slot 11.

[0038] When the adjusting column 2 is slid outwardly to extend out of the insertion slot 11 to the desired length, the first spring 42 under pressure always pushes the limiting block 41 to move out of the sliding groove 12, and then pushes the pointed portion 411 of the limiting block 41 into the limiting groove 22 opposite to the side wall of the adjusting column 2. When the pointed portion 411 of the limiting block 41 is embedded in the inside of any limiting groove 22 on the side wall of the adjusting column 2, the pointed portion 411 of the limiting block 41 is in contact with the contact wall 221 of the limiting groove 22, and the contact wall 221 is arranged perpendicularly to the extension direction of the insertion slot 11, that is, the limiting block 41 at this time plays a role of lifting and limiting the adjusting column 2, that is, the locking assembly 4 can prevent the adjusting column 2 from sliding inwardly into the insertion slot 11 due to gravity.

[0039] In some embodiments, as shown in the drawings, Figure 4 and Figure 8As shown, the open end of the base column 1 is provided with a reset slot 13 vertically penetrating the sliding slot 12, and a reset rod 43 is slidingly arranged in the reset slot 13; the limiting block 41 has an adjusting slot 412 with a notch facing the reset slot 13, the longitudinal section of the adjusting slot 412 is trapezoidal, and the adjusting slot 412 has an adjusting wall 412a which is arranged away from the insertion slot 11 and is inclined, that is, the adjusting wall 412a of the adjusting slot 412 is arranged in an inverted eight-shaped manner with the sliding surface wall 222 of the limiting slot 22, and the reset rod 43 has a convex part 431 which abuts against the adjusting wall 412a. The end of the reset rod 43 inserted into the reset slot 13 is provided with a second spring 44 between the opposite surfaces of the reset slot 13.

[0040] In summary, when it is necessary to autonomously control the adjusting column 2 to slide and shrink into the insertion slot 11, the reset rod 43 is moved into the reset slot 13 by pressing, and the second spring 44 is compressed, the convex part 431 on the reset rod 43 is in contact with the adjusting wall 412a arranged obliquely on the adjusting slot 412, and then the limiting rod is pressed to move into the sliding slot 12 and the first spring 42 is compressed, so that the sharp part 411 of the limiting rod is removed from the corresponding limiting slot 22, and the limiting of the sliding and shrinking of the adjusting column 2 into the insertion slot 11 is released. At this time, the adjusting column 2 can slide and shrink into the insertion slot 11 under the action of gravity, and the adjusting column 2 can also be held by hand to slowly control the adjusting column 2 to slide and shrink into the insertion slot 11. When the adjusting column 2 is shrunk to a specified length, the finger pressing the reset rod 43 is released, and the reset rod 43 and the limiting block 41 are pushed to reset under the elastic reset action of the first spring 42 and the second spring 44, so that the sharp part 411 of the limiting block 41 is reinserted into the directly opposite limiting slot 22.

[0041] In some embodiments, as Figure 1 As shown, in order to further increase the stability of the foundation pit full-cover tent support device of the subunit, the end of the base column 1 away from the opening of the insertion slot 11 is detachably connected with a support 5.

[0042] Finally, it should be pointed out that the above detailed description of the method and device is only an embodiment, and those skilled in the art can modify the embodiment in different ways without departing from the scope of the present application.
