Description

Technical Field

[0001] The utility model relates to the field of construction enclosures, in particular to a portable construction enclosure with a folding function. Background Art

[0002] Fencing is a kind of outer shielding used in urban construction sites. Its main function is to isolate the construction site from the outside world, turning the construction site into a relatively closed environment to avoid interference from the outside environment during construction. It also plays a protective role to ensure the safety of residents outside.

[0003] Most of the existing construction fences are made by splicing several metal plates and then fixing them through support rods. Finally, multiple such combinations are connected through connectors to form a complete construction fence. This type of construction must be repeatedly disassembled and assembled before it can be retracted or unfolded, which results in a lot of time being spent in the disassembly and assembly process. At the same time, because the fence is a metal plate and the size of each plate is fixed, the height of the fence cannot be adjusted, which greatly reduces the practicability of the fence. For this reason, a portable construction fence with a folding function is proposed to solve the above problems. Summary of the invention

[0029] 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 in 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.

[0030] Reference Figure 1-4 The utility model provides an embodiment: a portable construction fence with a folding function, comprising two telescopic frames 1, the telescopic frames 1 are fixedly connected to the opposite sides with a fixing member 5, the bottoms of the two telescopic frames 1 are slidably connected with a telescopic frame 2, the telescopic frame 2 is fixedly connected with a plurality of evenly distributed wheels 13, the upper part of the telescopic frame 2 is fixedly connected with a fixing member 29 on the opposite side, the telescopic frame 2 is rotatably connected with a handle 14 on the separated side, the fixing member 29 is rotatably connected with a fence cross bar 2 10 on the opposite side, the two fixing members 29 are rotatably connected to the fence cross bar 2 10 on the opposite side, the fence cross bar 2 10 is rotatably connected with a connecting member 2 11 on the opposite side, a plurality of fence vertical bars 12 are evenly distributed on the upper part of the fence cross bar 2 10, the top of the fence vertical bar 12 is fixedly connected with a fence cross bar 1 8, the tops of the plurality of fence vertical bars 12 are fixedly connected to the bottom of the fence cross bar 1 8, and the bottoms of the plurality of fence vertical bars 12 are fixedly connected to the fence cross bar 2 10 top.

[0031] Specifically, the wheel 13 is a universal wheel in the prior art, which has functions such as rotation and self-locking. The fixing part 29, the handle 14 and the fixing part 29 are all hardware standard parts of the existing mature technology, which have the function of anti-corrosion and anti-rust. The fence crossbar 18 is rotatably connected to the fixing part 15 at the separated end, the top of the fixing part 15 is fixedly connected to the spring rod 6, the bottom of the spring rod 6 is rotatably connected to the connecting part 17, the top of the fixing part 15 is rotatably connected to the telescopic rod 3, the top of the telescopic rod 3 is rotatably connected to the fixing part 15 at the opposite end, the top of the telescopic frame 1 is provided with a fixing hole 4, the telescopic rod 3 is slidably connected inside the fixing hole 4, and the telescopic frame 22 is provided with a lifting component inside.

[0032] Specifically, the fixing member 5 and the telescopic rod 3 are both standard hardware parts of existing mature technology, so they are not described in detail. When the spring rod 6 is fully retracted, it just matches the minimum thickness of the enclosure after folding.

[0033] The lifting assembly includes two threaded rods 15, which are rotatably connected to the inner bottom of the telescopic frame 2, and the outer circumference of the threaded rod 15 is threadedly connected to a worm wheel 16, and the outer circumference of the worm wheel 16 is meshedly connected to a worm 17.

[0034] Specifically, through the cooperation of the above components, the height of the entire enclosure can be adjusted.

[0035] Working principle: When the telescopic frame 1 needs to be raised or lowered, the handle 14 is rotated to drive the worm 17 to rotate. When the worm 17 rotates, the worm 17 will mesh with the teeth of the worm wheel 16, thereby transmitting the rotational force to drive the threaded rod 15, so that the telescopic frame 1 fixed on the threaded rod 15 can be adjusted in height, and the vertical rod 12 of the fence can be raised or lowered.

[0036] When it is necessary to fold the fence crossbar 1 8 and the fence crossbar 2 10, first loosen the screws of the connector 1 7 and the connector 2 11, and then push the two telescopic frames 2. When the two telescopic frames 2 move towards each other, the spring rod 6 contracts. When the spring rod 6 is fully contracted and the two telescopic frames 2 are close to each other, tighten the screws of the connector 1 7 and the connector 2 11, so that the entire enclosure is folded and fixed.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
