[0018] Based on the above structural features of the present application, the implementation methods of the present application are further described: Reference Figure 1 The present embodiment provides an adjustable edge protection device, comprising a plurality of columns 1, a plurality of telescopic plates 2 and a plurality of double-sided connectors 3. The telescopic plates 2 are arranged between adjacent columns 1, and the edges of the two sides of the telescopic plates 2 are respectively connected to the columns 1 through the double-sided connectors 3. The plurality of columns 1 are adapted to be installed on the ground at the construction site in a broken line or stepped shape, and the side edges of the telescopic plates 2 are connected to the columns 1, thereby achieving the purpose of the present invention to adapt to the complex terrain of the construction site.

[0019] Reference Figure 1 and Figure 2 The column 1 includes a column 11, a connecting fin 12 and a guide tip 13. The connecting fin 12 is vertically fixedly installed at the bottom of the column 11 (for example, fixedly connected by welding or fixedly connected by bolts); the guide tip 13 is detachably installed at the top of the column 11 (for example, detachably connected by bolts or detachably connected by threads). The guide tip 13 is used to conveniently sleeve the double-sided connecting member 3 on the side wall through the top of the column 11 when the double-sided connecting member 3 is pre-assembled.

[0020] Reference Figure 3 and Figure 4 , a single telescopic plate 2 includes a first plate body 21 and two second plate bodies 22. The first plate body 21 and the second plate body 22 are both straight plate structures with rectangular edges. The first plate body 21 is a shell-like structure with openings on both sides, and the two second plate bodies 22 are respectively inserted and arranged at the left and right edge positions of the inner cavity of the first plate body 21 and can slide laterally; a plurality of positioning holes 211 are provided at the bottom of the side wall of the first plate body 21, and the cross-section of the positioning holes 211 is rectangular; a pop-up bouncing protrusion 221 is provided at the bottom end of the side wall of the second plate body 22, and the bouncing protrusion 221 is selectively inserted into the positioning hole 211, thereby limiting the relative position of the first plate body 21 and the second plate body 22, thereby limiting the length of the telescopic plate 2; when the bouncing protrusion 221 is inserted into different positioning holes 211, the telescopic plate 2 has different lengths to adapt to the complex environment of the construction site and the spacing between adjacent columns 1.

[0021] Reference Figure 4, a first bolt hole 2212 is provided at the end of the bouncing protrusion 221; the first bolt hole 2212 is opened at the center position of the outer end surface of the bouncing protrusion 221. The adjustable edge protection device also includes a plurality of positioning bolts 4 and gaskets 5, and the positioning bolts 4 are adapted to be screwed with the first bolt holes 2212. The inner diameter of the gasket 5 is smaller than the outer diameter of the column head of the positioning bolt 4, and the gasket 5 is sleeved on the stud surface of the positioning bolt 4 and can be crimped with the column head of the positioning bolt 4. The outer diameter of the gasket 5 is larger than the maximum diameter of the positioning hole 211; when the positioning bolt 4 is tightened in the first bolt hole 2212, the column head crimps the middle position of the gasket 5 so that the outer edge of the gasket 5 is crimped on the side wall of the first plate body 21 to prevent the positioning bolt 4 from being embedded in the positioning hole 211. The positioning bolt 4 embedded in the positioning hole 211 will cause three problems: the positioning bolt 4 cannot apply a locking force between the first plate 21 and the second plate 22; the user cannot insert a wrench into the positioning hole 211 to tighten the positioning bolt 4; the user cannot insert a wrench into the positioning hole 211 to unscrew the positioning bolt 4. The positioning bolt 4 is an external hexagonal bolt; the washer 5 is annular.

[0022] Reference Figure 4 and Figure 5 The aspect ratio of the cross section of the positioning hole 211 is not less than 2, so that the end of the bouncing protrusion 221 can slide laterally in the positioning hole 211, thereby achieving fine adjustment of the length of the telescopic plate 2.

[0023] Reference Figure 4 and Figure 5 The side wall of the gasket 5 is fixedly connected to a limiting ring body 51 (for example, through an integrated fixed connection), and the cross section of the limiting ring body 51 is rectangular and fits the positioning hole 211; the length of the cross section of the limiting ring body 51 is less than 1 / 2 of the length of the cross section of the positioning hole 211, so that the limiting ring body 51 can be selectively installed on the left side, right side or middle position of the positioning hole 211. The top and bottom surfaces of the limiting ring body 51 are respectively matched with the top and bottom surfaces of the positioning hole 211, so as to realize the convenient insertion and removal of the limiting ring body 51. Figure 5 A first rack structure is respectively provided on the top and bottom surfaces of the positioning hole 211, and a second rack structure adapted to the first rack structure is respectively provided on the top and bottom surfaces of the limiting ring body 51. The user can selectively insert the second rack structure into any tooth groove of the first rack structure, thereby realizing the clamping connection between the limiting ring body 51 and the positioning hole 211, avoiding the limiting ring body 51 from sliding along the length direction of the cross section of the positioning hole 211, that is, avoiding the relative movement of the first plate body 21 and the second plate body 22, and realizing the locking of the telescopic plate 2 after fine adjustment.

[0024] Reference Figure 4The end of the bouncing protrusion 221 can be inserted into the inner cavity of the limiting ring body 51; a first through hole 2201 is opened at the bottom of the side wall of the second plate body 22 to accommodate the end of the bouncing protrusion 221, and the end of the bouncing protrusion 221 can extend from the second plate body 22 through the first through hole 2201, thereby being inserted into the positioning hole 211.

[0025] Reference Figure 4 The bottom of the second plate body 22 is a hollow shell-like structure, and a horizontal plug-in column 222 is fixedly installed in the inner cavity of the second plate body 22. The plug-in column 222 includes a limiting column 2221 and a side support fin 2222 that are fixedly connected in a T-shape (for example, through an integrated fixed connection); the limiting column 2221 is inserted into the inner cavity of the end of the bouncing protrusion 221, and the limiting column 2221 is a hollow columnar structure with openings on both sides, and a compression spring 223 is provided in the inner cavity of the limiting column 2221. One end of the compression spring 223 is pressed against the side support fin 2222, and the other end is pressed against the bottom surface of the inner cavity of the bouncing protrusion 221. Under the pushing action of the compression spring 223, the bouncing protrusion 221 has a tendency to extend from the first through hole 2201 and the positioning hole 211.

[0026] Reference Figure 4 The side support fin 2222 is fixedly connected to the bottom of the inner cavity side wall of the second plate body 22 by bolts.

[0027] The cross-section of the limiting column 2221 is rectangular, and the cross-section of the inner cavity of the bouncing protrusion 221 is a rectangle that matches the surface of the limiting column 2221, thereby preventing the bouncing protrusion 221 from rotating, so that the positioning bolt 4 can be easily screwed into the first bolt hole 2212, rather than causing the bouncing protrusion 221 to passively rotate under the action of the thread friction force of the positioning bolt 4.

[0028] Reference Figure 4 The side wall of the bouncing protrusion 221 is fixedly connected with an abutting fin 2211 (for example, by an integral fixed connection or by a bolt fixed connection), and the abutting fin 2211 is annular and abuts against the first through hole 2201 on the inner wall of the second plate body 22. After the positioning bolt 4 is removed, the abutting fin 2211 is used for the bouncing protrusion 221 to escape from the first through hole 2201 and the positioning hole 211.

[0029] Reference Figure 6 and Figure 7 The single double-sided connecting member 3 includes two first hoop rings 31 and one second hoop ring 32. The two first hoop rings 31 are respectively arranged on the upper and lower sides of the second hoop ring 32; the second plate body 22 is connected to the first hoop ring 31 or the second hoop ring 32. The first hoop ring 31 and the second hoop ring 32 are respectively used to support the second plate body 22 on both sides. The first hoop ring 31 and the second hoop ring 32 are both sleeved on the side wall of the column 1 and connected by friction.
