DETAILED DESCRIPTION

[0026] In order to further understand the characteristics, technical means and specific purposes and functions reached by the utility model, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0027] Referring to Figures 1-5 As shown in the figure, a portable civil engineering fence device comprises a pair of butt joint plates 1 arranged oppositely, a fence board 2 arranged between the two butt joint plates 1 and a rain shield 3 arranged on the top of the fence board 2, and further comprises an adjusting mechanism 4;The adjusting mechanism 4 has a pair of adjusting plates 41 and pulling blocks 42 arranged on the two sides of the fence board 2 respectively;The adjusting plate 41 has a pair of adjusting plates 41 and pulling blocks 42 arranged on the two sides of the rain shield 3 respectively;The two sides of the rain shield 3 are provided with a sliding groove for the sliding of the adjusting plate 41;The pulling block 42 has a pair of pulling blocks 42 and is slidably arranged on the two sides of the fence board 2.

[0028] When the rain-shielding range of the rain shield 3 needs to be adjusted, the user standing below the rain shield 3 pulls the pulling block 42 downwards, and when the pulling block 42 is lowered, the adjusting plate 41 can be driven to slide and extend outside the rain shield 3, thereby realizing the adjustment of the rain-shielding range and improving the practicability. The abutting plate 1, the enclosing plate 2 and the rain shield 3 are all installed through bolts, and the whole is convenient to disassemble and install.

[0029] Referring to Figures 3-5 The adjusting mechanism 4 further comprises a first positioning rod 43 and a second positioning rod 44. The first positioning rod 43 is arranged at the bottom of the adjusting plate 41, and the first positioning rod 43 is located above the enclosing plate 2. The second positioning rod 44 is arranged at the top of the pulling block 42.

[0030] When the adjusting plate 41 moves, the first positioning rod 43 can be driven to move synchronously. When the pulling block 42 moves, the second positioning rod 44 can be driven to move synchronously.

[0031] Referring to Figures 3-5 The adjusting mechanism 4 further comprises a connecting rod 45. The connecting rod 45 is rotatably arranged outside the second positioning rod 44. One end of the connecting rod 45 is rotatably connected with the second positioning rod 44, and the other end of the connecting rod 45 is rotatably connected with the first positioning rod 43.

[0032] When the user pulls the pulling block 42, the pulling block 42 is in a descending movement state in this process. When the pulling block 42 moves, the adjusting plate 41 can be pulled to slide along the rain shield 3 through the rotatably connected connecting rod 45. The position of the adjusting plate 41 is adjusted to increase the rain-shielding area of the rain shield 3.

[0033] Referring to Figure 4 and Figure 5 The adjusting mechanism 4 further comprises a positioning plate 46. The positioning plate 46 has a pair of and is arranged on both sides of the enclosing plate 2 respectively. The top of the pair of positioning plates 46 is provided with a displacement slot for the sliding of the pulling block 42.

[0034] The positioning plate 46 can be quickly installed to both sides of the enclosing plate 2 through fasteners 47. The pulling block 42 can slide upwards or downwards along the displacement slot provided at the top of the positioning plate 46.

[0035] Referring to Figure 5 The adjusting mechanism 4 further comprises fasteners 47. The fasteners 47 are rotatably arranged beside the pulling block 42. The fasteners 47 can be in abutment with the enclosing plate 2 through the screwing-in mode.

[0036] When the pulling block 42 stops moving and the user has adjusted the position of the adjusting plate 41, the user rotates the fastener 47 again until the fastener 47 abuts against the side of the enclosing plate 2. The position of the sliding pulling block 42 is fixed, and the pulling block 42 can be effectively prevented from sliding downward due to the gravity of the adjusting plate 41.

[0037] Referring to Figure 5 and Figure 6 As shown in the figure, the adjusting mechanism 4 further comprises a pulling plate 48. The pulling plate 48 is arranged beside the pulling block 42, and a circular opening is formed in the top of the pulling plate 48.

[0038] When the user needs to adjust the position of the pulling block 42, the user should first hold the pulling plate 48 by fingers in the circular openings formed in the top of the pulling plate 48. Then the pulling block 42 can be pulled by the pulling plate 48, achieving the purpose of saving labor.

[0039] Referring to Figure 1 As shown in the figure, the two sides of the enclosing plate 2 are provided with a plurality of first flow guide grooves 21 for air to pass through, and the sizes of the plurality of first flow guide grooves 21 are sequentially decreased from top to bottom.

[0040] When the wind is relatively large, the wind enters through the first flow guide grooves 21 formed in the two sides of the enclosing plate 2.

[0041] Referring to Figure 1 As shown in the figure, the two sides of the enclosing plate 2 are provided with a plurality of second flow guide grooves 22 connected with the first flow guide grooves 21, and the plurality of second flow guide grooves 22 are all located below the first flow guide grooves 21 and penetrate through the bottom of the enclosing plate 2.

[0042] When the wind flows through the first flow guide grooves 21, the wind direction changes and then enters the second flow guide grooves 22. In the second flow guide grooves 22, the wind direction is further changed to a vertical downward direction. When the wind is relatively large, the air sequentially passes through the first flow guide grooves 21 and the second flow guide grooves 22 and finally blows to the ground. In this process, the wind force generates a downward pressure at the positions of the first flow guide grooves 21 and the second flow guide grooves 22, so that the enclosing plate 2 can still be stably connected with the ground in an environment with relatively large wind force.

[0043] The above embodiments only express one or several embodiments of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
