DETAILED DESCRIPTION

[0017] The technical solutions in the utility model will be further described below in combination with the drawings and embodiments.

[0018] As Figs. 1-3 shown, the utility model discloses an assembly type construction fence, including support unit, connecting pin 4, support unit is several, every support unit all includes two uprights 1, two uprights 1 relative one side all along its length direction symmetry is equipped with two first wing plate 2, and is equipped with first baffle 3 between two first wing plate 2, every upright 1 is away from first wing plate 2 one side all is detachably equipped with connecting lug 5, and connecting pin 4 is worn and is equipped with the connecting lug 5 on two support units of adjacent two, make two support units between each other rotate, every upright 1's top all are set up with slide groove, every slide groove all are equipped with extension column 6 of sliding, every upright 1's side wall all is equipped with the limiting piece 7 of limiting extension column 6 sliding, every extension column 6's at least one side wall along its length direction is equipped with two second wing plate 8, and the second wing plate 8 between two extension columns 6 opposite sides of same support unit all are equipped with several second baffles 9. In this embodiment, several support units are connected in head and tail and enclose the fence range of the protection of construction area, specifically, two uprights 1 of same support unit are supported on the ground, adjust the interval between two uprights 1, the both ends of first baffle 3 are clamped into the first recess groove formed by two first wing plates 2 of upright 1 respectively, the connecting lug 5 on upright 1 is connected between different support units, so that two support units can rotate each other to enclose a ring, when the height of fence needs to be improved, extension column 6 is stretched out from the slide groove, after extension column 6 is stretched out from the slide groove by a predetermined distance, locking is performed by limiting piece 7, then second baffle 9 (the both ends of the second baffle 9 located at the bottom are supported by the top of upright 1) is clamped between the second recess groove formed by two second wing plates 8 of upright 1, thereby improving the height of fence, adapting to different construction conditions, when not used subsequently, first baffle 3 and second baffle 9 can be removed and extension column 6 can be stored in the slide groove, thereby reducing the occupied space.

[0019] As Figs. 1-3 shown, further, the side wall of every upright 1 is provided with a limiting hole for the limiting piece 7 to pass through, and every extension column 6 is provided with insertion holes 10 for the limiting piece 7 to insert at equal intervals. Specifically, in this embodiment, four insertion holes 10 are provided on every extension column 6 at equal intervals, when the extension column 6 is stretched to the maximum length, one end of the limiting piece 7 passes through the limiting hole on the upright 1 and is inserted into the insertion hole 10 at the bottom of the extension column 6, three second baffles 9 are clamped between the two extension columns 6 from top to bottom in sequence, when the extension height of the extension column 6 is reduced, the extension column 6 is retracted into the slide groove by releasing the limiting piece 7, if the limiting piece 7 is inserted into the second insertion hole 10 from bottom to top of the extension column 6 after passing through the limiting hole, then two second baffles 9 can be clamped between the two extension columns 6. Preferably, the limiting hole is an internally threaded hole, and the limiting piece 7 is a bolt.

[0020] As Figs. 1-3As shown in the drawings, further, the limiting cap 11 is provided with a threaded hole in the bottom, and each of the extension columns 6 is provided with a threaded column 12 at the top for screwing with the limiting cap 11. In the embodiment, when the extension columns 6 are used to increase the height of the fence, the second fence 9 is clamped between the two extension columns 6, and the limiting cap 11 is screwed with the threaded column 12 at the top of the extension column 6, so that the bottom of the limiting cap 11 abuts against the top of the topmost second fence 9, thereby limiting the second fence 9 from being pulled out of the two extension columns 6.

[0021] As shown in the drawings, Figs. 1-3 Further, at least one extension block 13 is arranged on each side wall of the upright column 1, each of the extension blocks 13 is hingedly provided with a support rod 14, and a sharp part 15 is arranged on the free end of each of the support rods 14. When the upright column 1 is supported on the ground, the support rods 14 are rotated, and the sharp parts 15 on the free ends of the support rods 14 are inserted into the soil near the construction area, so as to enhance the support strength of the upright column 1 and improve the stability of the upright column 1. Preferably, the extension blocks 13 and the support rods 14 are arranged on the opposite side walls of the upright column 1, and the line connecting the two extension blocks 13 is perpendicular to the line connecting the connecting lug 5 and the two wing plates.

[0022] Further, each of the support rods 14 is a telescopic rod. The telescopic structure of the support rod 14 can be selected from the prior art, such as electric type, sleeve type, screw type, etc. By adjusting the telescopic structure of the support rod 14, the support rod 14 can be supported at a suitable position.

[0023] As shown in the drawings, Fig. 1 Further, a base plate 16 is arranged at the bottom of each of the upright columns 1, and two positioning holes 17 are symmetrically arranged on the base plate 16, and the two positioning holes 17 are respectively located on the same side of the two extension blocks 13. The base plate 16 arranged at the bottom of the upright column 1 can increase the contact area between the upright column 1 and the ground, and further improve the stability of the upright column 1. When the device is used, the base plate 16 is fixed to the ground by the positioning pin passing through the positioning hole 17, and when the device is not used, the sharp part 15 at the free end of the support rod 14 is inserted into the positioning hole 17, so as to limit the rotation of the support rod 14 around the hinged end, and facilitate storage.

[0024] Further, the cross section of the sliding groove is in the shape of an I-beam. Since the side wall of the extension column 6 is provided with the second wing plate 8, the I-beam-shaped sliding groove can adapt to the shape formed by the extension column 6 and the wing plate, and the wing plate simultaneously guides the sliding of the extension column 6.

[0025] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
