[0002] Water barrier is an important guarantee facility for civilized construction of urban municipal engineering and construction projects. It can not only improve construction safety, but also maintain the cityscape.

[0003] At present, most of the traditional water barrier enclosures on the market are of integrated design. Traditional water barrier enclosures are characterized by light weight and strong weather resistance. However, traditional water barrier enclosures also have some disadvantages. For example, traditional water barrier enclosures are large in size, which is not conducive to transportation and storage, and the height of traditional water barrier enclosures is fixed, which has poor applicability. Utility Model Content

[0004] The purpose of the utility model is to provide a counterweight type foldable enclosure, which can be folded longitudinally for easy transportation and storage, and has the advantages of easy installation and stable structure.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A counterweight type foldable enclosure, comprising a base and a folding enclosure;

[0007] The folding enclosure includes a top plate and a bottom plate, the bottom plate is fixed on the base, and a folding portion is connected between the top plate and the bottom plate, the folding portion can be expanded or compressed in the longitudinal direction, and support frames for reinforcement are provided on both sides of the folding enclosure.

[0008] Compared with the prior art, the advantages of the present invention are:

[0009] 1. By providing a folding portion, the foldable enclosure can be expanded or compressed in the longitudinal direction, and by cooperating with the slot on the base, the foldable enclosure can be accommodated in the slot when not expanded, further reducing the overall volume of the enclosure and making it easier to transport and store;

[0010] 2. By setting up an articulated seat, the retractable legs can be retracted and retracted synchronously with the expansion or compression of the folding enclosure, and by cooperating with the compression spring pieces and multiple positioning holes, the two retractable legs in the same support assembly can be relatively locked at different heights, thereby achieving the effect of adjustable height of the folding enclosure, which not only improves the applicability of the water barrier enclosure, but also enhances the structural strength and overall stability of the folding enclosure.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0020] like Figure 1-7 The figure shows a schematic diagram of an embodiment of a counterweight-type foldable enclosure provided by the present invention:

[0021] A counterweight type foldable enclosure, comprising a base 1 and a foldable enclosure 2;

[0022] The folding enclosure 2 includes a top plate 21 and a bottom plate 22. The bottom plate 22 is fixed on the base 1, and a folding portion 23 is connected between the top plate 21 and the bottom plate 22. The folding portion 23 can be expanded or compressed in the longitudinal direction, and support frames for reinforcement are provided on both sides of the folding enclosure 2.

[0023] The foldable enclosure 2 is made of a plastic material with a certain ductility, such as high-density polyethylene or polypropylene.

[0024] Furthermore, the top plate 21 , the bottom plate 22 and the folding portion 23 are integrally formed.

[0025] The top surface of the base 1 is provided with a downwardly recessed slot 101 , and the bottom plate 22 is fixed to the bottom surface of the slot 101 . When the folding portion 23 is not unfolded, the entire foldable enclosure 2 can be accommodated in the slot 101 .

[0026] The support frame includes two support assemblies 3 spaced apart from each other in the front and rear directions. The support assembly 3 includes two hinged seats 301 and two retractable legs 302. The two hinged seats 301 are fixed to the top plate 21 and the bottom plate 22 respectively, and one end of the two retractable legs 302 is hinged to the two hinged seats 301 respectively.

[0027] A hinge shaft 303 is provided on the free end of one of the retractable legs 302, and a compression spring 304 is provided on the side of the hinge shaft 303. An axial hole that cooperates with the hinge shaft 303 is provided on the free end of the other retractable leg 302, and a positioning hole is provided on the inner wall of the axial hole to allow the compression spring 304 to pop out.

[0028] There are a plurality of positioning holes, and the plurality of positioning holes are circumferentially spaced around the shaft hole.

[0029] By setting up the hinge seat 301, the retractable legs 302 can be retracted and retracted synchronously with the expansion or compression of the folding enclosure 2. When the folding enclosure 2 is gradually expanded, the hinge shaft 303 and the shaft hole rotate relative to each other. After the hinge shaft 303 and the shaft hole rotate relative to each other by a certain angle, the compression spring piece 304 on the hinge shaft 303 matches the positioning hole and pops out of the positioning hole, so that the hinge shaft 303 can no longer rotate relative to the shaft hole, thereby achieving relative locking of the two retractable legs 302 in the same support assembly 3.

[0030] The top plate 21 is provided with a handle 4 for facilitating pulling up or pressing down the foldable enclosure 2 .

[0031] Furthermore, the handle 4 and the top plate 21 are integrally formed.

[0032] The folding portion 23 is connected between the outer peripheries of the top plate 21 and the bottom plate 22 , and a cavity is formed between the folding portion 23 , the top plate 21 and the bottom plate 22 . A vent 201 communicating with the cavity is provided on the folding enclosure 2 .

[0033] In some embodiments, the vent 201 is provided on the bottom plate 22 , and the bottom plate 22 is separated from the slot 101 by a hinge seat 301 , so that the vent 201 can smoothly deliver air into or out of the cavity.

[0034] A counterweight space is provided in the base 1 , and an injection port 102 and an outlet 103 communicating with the counterweight space are provided on the base 1 .

[0035] The injection port 102 is provided at the upper portion of the side wall of the base 1 , and the discharge port 103 is provided at the lower portion of the side wall of the base 1 . Liquid or fine sand can be poured into the counterweight space from the injection port 102 according to actual site conditions.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
