Description

Technical Field

[0001] The utility model relates to the technical field of enclosures, in particular to a dust-proof construction enclosure. Background Art

[0002] Construction fencing is a facility used to isolate construction areas and ensure construction safety at construction sites or other construction sites. Construction fencing is usually made of fences, baffles, protective nets and other materials. Its purpose is to prevent construction objects or debris from splashing and injuring people, avoid nearby pedestrians and vehicles from entering, and reduce the impact of noise and dust on the surrounding environment. Construction fencing can effectively improve the safety of the construction site, protect the surrounding environment, and ensure the smooth progress of construction.

[0003] In the existing patent literature, there is a patent document with the publication number CN 214195816 U and the patent name "Construction Fence". The existing technology is mainly composed of a frame and a fence. Although it can prevent the entry of pedestrians and vehicles, when there is windy weather, the dust on the construction site will be blown up by the wind. The frame and the fence cannot block the dust, which is easy to cause damage to the external environment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a dust-proof construction fence. When strong winds occur, in order to avoid dust, a windproof cloth can be pulled down to block the wind. When the hook is hung on the hanging core, the windproof cloth can cover the entire surface of the main frame, and the dust will be intercepted within the construction fence, thereby reducing pollution to the outside world.

[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:

[0006] A dust-proof construction enclosure comprises a main frame, a plurality of longitudinally distributed ribs are fixed on the main frame, a plurality of lower fixed legs are fixed on the bottom of the main frame, and each two adjacent main frames are uniformly fixedly connected by a plurality of transversely arranged connecting plates;

[0007] The interior of the main frame is hollow, and a reel is hidden in the upper crossbeam of the main frame. The windproof cloth is stored in the reel. An avoidance groove is provided at the bottom of the upper crossbeam of the main frame. The windproof cloth can pass through the avoidance groove and stretch vertically downward. A hook is fixedly connected to the end of the windproof cloth, and a hanging core used in conjunction with the hook is fixed on the lower crossbeam of the main frame. When the hook is hung on the hanging core, the windproof cloth can cover the entire surface of the main frame.

[0008] By adopting the above scheme, the construction fence is equipped with a hidden reel, so that the construction fence can be used as an ordinary fence in windless weather. When there is strong wind, in order to avoid dust, the windproof cloth can be pulled down to block the wind. When the hook is hung on the hanging core, the windproof cloth can cover the entire surface of the main frame, and the dust will be intercepted inside the construction fence, thereby reducing pollution to the outside world.

[0009] As an optimal implementation scheme for anti-dust construction fence, longitudinally arranged lifting rods are fixed on the left and right ends of the reel respectively. The lifting rods are hidden in the left and right longitudinal beams of the main frame. The lifting rods are provided with multiple lifting holes in a linear array along their length direction. The main frame is installed with a plug-in lifting adjustment component used in conjunction with the lifting holes.

[0010] By adopting the above scheme, in order to further improve the height of dust prevention, a lifting rod is provided to raise the height of the retractor, wherein the height of the lifting rod is adjusted by a plug-in lifting adjustment component.

[0011] As a preferred implementation of a dust-proof construction enclosure, the plug-in lifting and adjusting assembly and the lifting and lowering holes are both located on the inner side of the main frame.

[0012] With the above solution, in order to facilitate the operation of the staff inside the enclosure, the plug-in lifting adjustment component and the lifting hole are arranged on the inner side of the main frame, so that the staff can operate in time.

[0013] As a preferred embodiment of an anti-dust construction fence, the plug-in lifting and adjustment assembly includes a mounting seat, a pin that is used in conjunction with a lifting hole, sliding seats are fixed on both sides of the pin body of the pin, and the sliding seat is slidably installed on a sliding rod fixed on the mounting seat. The sliding rod is equipped with a spring, which can push the sliding seat to move toward the lifting hole.

[0014] By adopting the above scheme, when the plug-in lifting adjustment component is performing lifting adjustment, the pin is pulled outward, the spring is compressed, and the pin is disengaged from the lifting hole, so that the height of the lifting rod can be adjusted. After the height is determined, the pin is released, and the pin is pushed by the elasticity of the spring to cooperate with the nearest lifting hole, thereby completing the lifting adjustment of the lifting rod.

[0015] As a preferred implementation method of a dust-proof construction enclosure, the ribs are evenly and alternately distributed along the front and rear sides of the avoidance groove.

[0016] By adopting the above scheme, in order not to hinder the stretching of the windproof cloth, the ribs are evenly distributed alternately along the front and rear sides of the avoidance groove. This will not affect the pulling of the windproof cloth from the avoidance groove. At this time, the ribs are distributed on the front and rear sides of the windproof cloth. The ribs can also restrain the windproof cloth to a certain extent, thereby preventing the windproof cloth from "fluttering" in strong winds.

[0017] As a preferred implementation of an anti-dust construction enclosure, the lower fixed legs are detachably fixed to the main frame by bolts.

[0018] By adopting the above scheme, in order to facilitate the transportation of the construction fence, the lower fixed legs and the main frame can be installed and fixed after arriving at the destination, thereby improving the convenience during transportation.

[0019] As a preferred implementation of a dust-proof construction enclosure, a plurality of evenly distributed drainage holes are provided through the bottom of the lower cross beam of the main frame.

[0020] In order to avoid water accumulation in the main frame, a drainage hole is provided at the bottom of the lower crossbeam of the main frame to prevent the accumulated water from corroding the interior of the main frame.

[0021] As a preferred implementation of a dust-proof construction enclosure, a pattern and a text introduction for promoting the construction project are printed on the outer side of the windproof cloth.

[0022] By adopting the above scheme, in order to increase the use of the windproof cloth, the pattern and text introduction of the construction project can be printed on the windproof cloth, thereby expanding the publicity of the construction project.

[0023] After adopting the above technical solution, the beneficial effects of the utility model are:

[0024] 1. The construction fence is equipped with a hidden retractor, so it can be used as an ordinary fence in windless weather. When it is windy, in order to avoid dust, the windproof cloth can be pulled down to block the wind. When the hook is hung on the hanging core, the windproof cloth can cover the entire surface of the main frame, and the dust will be intercepted inside the construction fence, thereby reducing pollution to the outside world.

[0025] 2. In order to further improve the height of dust prevention, a lifting rod is set to raise the height of the retractor, wherein the height of the lifting rod is adjusted by a plug-in lifting adjustment component; when the plug-in lifting adjustment component is performing lifting and adjustment, the pin is pulled outward, the spring is compressed, and the pin is disengaged from the lifting hole, so that the height of the lifting rod can be adjusted. After the height is determined, the pin is released, and the pin is pushed by the elasticity of the spring to cooperate with the nearest lifting hole, thereby completing the lifting and lowering adjustment of the lifting rod.

[0026] 3. In order to facilitate the operation of the staff inside the enclosure, the plug-in lifting adjustment component and the lifting hole are set on the inner side of the main frame, so that the staff can operate in time.

[0027] 4. In order not to hinder the stretching of the windproof cloth, the ribs are evenly distributed along the front and rear sides of the avoidance groove in turn. This will not affect the pulling of the windproof cloth from the avoidance groove. At this time, the ribs are distributed on the front and rear sides of the windproof cloth. The ribs can also constrain the windproof cloth to a certain extent, thereby preventing the windproof cloth from "fluttering" in strong winds.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] like Figures 1 to 8 As shown, a dust-proof construction enclosure includes a main frame 1, nine longitudinally distributed ribs 2 are fixed on the main frame 1, three lower fixed legs 3 are fixed to the bottom of the main frame 1 by bolts, and each two adjacent main frames 1 are uniformly fixedly connected by a plurality of transversely arranged connecting plates 4;

[0045] The interior of the main frame 1 is hollow, and a retractor 5 is hidden in the upper crossbeam of the main frame 1. The retractor 5 accommodates a windproof cloth 6. An avoidance groove 7 is provided at the bottom of the upper crossbeam of the main frame 1. The windproof cloth 6 can pass through the avoidance groove 7 and stretch vertically downward. A hook 8 is fixedly connected to the end of the windproof cloth 6. A hanging core 9 used in conjunction with the hook 8 is fixed on the lower crossbeam of the main frame 1. When the hook 8 is hung on the hanging core 9, the windproof cloth 6 can cover the entire surface of the main frame 1; wherein, the outer surface of the windproof cloth 6 is printed with patterns and text introductions for promoting the construction project, which can expand the publicity of the construction project.

[0046] The construction fence is provided with a hidden retractor 5, so that the construction fence can be used as an ordinary fence in windless weather. When windy weather occurs, in order to avoid dust, the windproof cloth 6 can be pulled down to block the wind. When the hook 8 is hung on the hanging core 9, the windproof cloth 6 can cover the entire surface of the main frame 1, and the dust will be intercepted inside the construction fence, thereby reducing pollution to the outside world.

[0047] like Figures 9 to 12 As shown, longitudinally arranged lifting rods 10 are respectively fixed to the left and right ends of the retractor 5, and the lifting rods 10 are hidden in the left and right longitudinal beams of the main frame 1. The lifting rods 10 are provided with a plurality of lifting holes 11 in a linear array along the length direction thereof, and a plug-in lifting adjustment component 12 used in conjunction with the lifting holes 11 is installed on the main frame 1, and the plug-in lifting adjustment component 12 and the lifting holes 11 are both located on the inner side surface of the main frame 1.

[0048] In order to further improve the height of dust prevention, a lifting rod 10 is set to raise the height of the retractor 5, wherein the height of the lifting rod 10 is adjusted by a plug-in lifting adjustment component 12; in order to facilitate the operation of the staff inside the enclosure, the plug-in lifting adjustment component 12 and the lifting hole 11 are set on the inner side of the main frame 1, so as to facilitate the staff to operate in time.

[0049] like Fig.12 As shown, the plug-in lifting and adjusting component 12 includes a mounting seat 1201, through which passes a latch 1202 used in conjunction with the lifting hole 11, and slide seats 1203 are fixed on both sides of the pin body of the latch 1202. The slide seat 1203 is slidably installed on a slide rod 1204 fixed on the mounting seat 1201, and the slide rod 1204 is sleeved with a spring 1205, which can push the slide seat 1203 to move toward the lifting hole 11.

[0050] When the plug-in lifting and adjusting component 12 is performing lifting and adjusting, the pin 1202 is pulled outward, and the spring 1205 is compressed. The pin 1202 is disengaged from the lifting hole 11, and the height of the lifting rod 10 can be adjusted. After the height is determined, the pin 1202 is released. The pin 1202 is pushed by the elasticity of the spring 1205 so that the pin 1202 cooperates with the nearest lifting hole 11, thereby completing the lifting and adjusting of the lifting rod 10.

[0051] like Figure 5 and Fig. 9 As shown, the ribs 2 are evenly distributed alternately along the front and rear sides of the avoidance groove 7.

[0052] In order not to hinder the stretching of the windproof cloth 6, the ribs 2 are evenly and alternately distributed along the front and rear sides of the avoidance groove 7. This will not affect the pulling of the windproof cloth 6 from the avoidance groove 7. At this time, the ribs 2 are distributed on the front and rear sides of the windproof cloth 6. The ribs 2 can also constrain the windproof cloth 6 to a certain extent, thereby preventing the windproof cloth 6 from "fluttering" in strong winds.

[0053] like Figure 8 As shown, a plurality of evenly distributed drainage holes 13 are formed through the bottom of the lower cross beam of the main frame 1 .

[0054] In order to prevent water from accumulating in the main frame 1 , a drainage hole 13 is provided at the bottom of the lower cross beam of the main frame 1 , thereby preventing the accumulated water from corroding the interior of the main frame 1 .

[0055] The working principle of this utility model:

[0056] When in use, first fix the main frame 1 and the lower fixed support leg 3 with bolts, then use expansion screws to fix the lower fixed support leg 3 to the ground, and the installation of a single construction fence can be completed. Finally, the two adjacent construction fences are fixedly connected by the connecting plate 4 to complete the installation of the construction fence.

[0057] In windless weather, the construction fence can be used as an ordinary fence. Figure 3 to Figure 4 shown.

[0058] In breezy weather, the height of the dust is not too high. In order to avoid dust, the windproof cloth 6 is pulled down to block the wind. When the hook 8 is hung on the hanging core 9, the windproof cloth 6 can block the entire surface of the main frame 1, and the dust will be intercepted within the construction enclosure, thereby reducing pollution to the outside world. Figures 5 to 8 shown.

[0059] In strong wind weather, the height of dust will be higher. In order to avoid dust, by raising the height of the lifting rod 10, when using the plug-in lifting adjustment component 12 to perform lifting adjustment, by pulling out the pin 1202, the spring 1205 is compressed, and the pin 1202 is disengaged from the lifting hole 11, the height of the lifting rod 10 can be adjusted. After its height is determined, the pin 1202 is released. Under the elastic push of the spring 1205, the pin 1202 cooperates with the nearest lifting hole 11, thereby completing the lifting and lowering adjustment of the lifting rod 10, and finally pulling down the windproof cloth 6 to block the wind. When the hook 8 is hung on the hanging core 9, the windproof cloth 6 can block the entire surface of the main frame 1, and the dust will be intercepted within the construction enclosure, thereby reducing pollution to the outside world. Figures 9 to 12 shown.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
