Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an enclosure for environmentally friendly construction. Background Art

[0002] During the construction process, construction fences need to be set up around the construction site. Using construction fences to isolate an independent construction area can effectively prevent pedestrians from entering by mistake and eliminate safety hazards. Currently, construction fences are mostly divided into columns and panels. During installation, the columns need to be fixed on the ground, and then the two sides of the panels need to be fixed together with the columns, so as to connect multiple panels into fences. The entire installation process is cumbersome, time-consuming and labor-intensive, and the height of the existing fences cannot be adjusted. It is impossible to select different speeds according to user needs, and the flexibility of use is poor. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an environmentally friendly construction enclosure, which can simplify the installation process and adjust the enclosure height according to usage requirements.

[0005] On the basis of the above scheme and as a preferred scheme of the above scheme: the pulling rope can drive the first slider to slide and is hung on the first hanging ring. The first slider drives the first support rod to rotate and drives the top plate to rise and fall.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the pulling rope is hung on the first hanging rings at different positions, the first support rod can maintain different inclination angles, and the top plate is maintained at different heights.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the shielding cloth reel is installed in a reel box, both ends of the rotating shaft are rotatably installed on the reel box, and torsion springs are installed at both ends of the rotating shaft; a slender opening is provided under the reel box for the shielding cloth to pass through.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: shielding cloth reels are installed on the front and rear sides of the top plate, second hanging rings are provided on the front and rear sides of the base, and the telescopic mechanism is located between the shielding cloths on both sides.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a card block is provided at the left end of the base, and a card slot cooperating with the card block is provided at the right end, and adjacent enclosures are connected through the card block and the card slot.

[0010] The construction process is as follows:

[0011] 1) In the initial state, under the gravity of the top plate and the shielding cloth reel, the first support rod and the second support rod are in a retracted state, the first slider and the second slider are both located at the far left, and the distance between the top plate and the base is the shortest, which is more convenient for storage and transportation;

[0012] 2) During installation, place the base on the ground and pull the pulling rope, which drives the first slider to slide to the right, that is, drives the left end of the first support rod to move to the right, and the first support rod and the second support rod rotate and cooperate, so that the second slider at the left end of the second support rod moves to the right synchronously, and the first support rod and the second support rod are in an unfolded state, and the top plate is lifted upward;

[0013] 3) First hanging rings at different positions are provided on the base, and the first hooks of the pulling rope are hung on different first hanging rings, which means that the first slider is stopped at different positions, so that the first support rod and the second support rod are at different inclinations, and finally the enclosure is at different heights;

[0014] 4) After the height of the top plate is fixed, the shielding cloth is pulled down so that the shielding cloth is pulled out from the reel box, and the second hook under the shielding cloth is hung on the second hanging ring of the base, thereby fixing the shielding cloth and completing the installation of a single enclosure;

[0015] 5) Engage the base of the second enclosure with the base of the previous enclosure and fix it, then follow the previous operation to complete the installation of the second enclosure, and so on, until all enclosures are installed.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. A scissor-type telescopic mechanism is set between the base and the top plate, and a pulling rope is used to control the expansion of the telescopic structure, which is simpler to operate and low in cost; a plurality of first hanging rings are provided on the base, so that the pulling rope can be fixed at different positions, which is convenient for users to keep the enclosure at different heights according to their needs.

[0018] 2. The shielding cloth of the enclosure is set in the form of a reel. The shielding cloth is wound on the rotating shaft, and a torsion spring is set on the rotating shaft. When the shielding cloth is pulled out, the rotating shaft will be subjected to the torsion force of the torsion spring. Therefore, the shielding cloth can be pulled out to a corresponding length according to the height of the enclosure, and the excess continues to be wound on the rotating shaft, so that the shielding cloth remains in a tensioned state and has a better aesthetic appearance.
