Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction site enclosure technology, and in particular to a construction site enclosure for preventing tipping. Background Technology
[0002] During construction, construction site fencing serves as an important safety protection facility, widely used to isolate the construction site from its surrounding environment. It not only effectively blocks the spread of dust, noise, and construction waste generated during construction, reducing disruption to the lives of nearby residents and traffic order, but also plays a crucial role in warning pedestrians and vehicles, demarcating construction areas, and ensuring construction safety.
[0003] Most construction site fences are currently made of a frame and sheet metal, which has low structural strength. At the same time, the enclosed structure is prone to collapse and breakage when encountering strong winds and excessive surface wind pressure, affecting the safety of pedestrians. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a construction site fence that prevents tipping over, effectively solving the deficiencies of the prior art.
[0005] To achieve the above objectives, one embodiment of this utility model provides a construction fence for preventing tipping, comprising a fixed frame, wherein a plurality of rotating shafts are rotatably connected to the center of the inner wall of the fixed frame, and a shielding blade plate is fixedly connected to the outer wall of each of the plurality of rotating shafts. The top of each of the plurality of rotating shafts extends through the top surface of the fixed frame and is fixedly connected to a connecting ear. A first connecting shaft is fixedly connected to the center of the edge of the top surface of the connecting ear away from the rotating shaft. A linkage rod is rotatably connected to the outer wall of the plurality of first connecting shafts. A shielding plate is fixedly connected to one edge of the top surface of the fixed frame. A support ear is fixedly connected to one side edge of the shielding plate. A second connecting shaft is fixedly connected to the center of the top surface of the support ear. A tension spring is fixedly connected to the outer wall of the second connecting shaft and the outermost first connecting shaft. When the plurality of shielding blade plates are opened, the tension spring is pulled open.
[0006] Preferably, in any of the above embodiments, fixing ears are fixedly connected to both bottom sides of the fixing frame, a fixing hole is provided on one side of the fixing ears, connecting pages are fixedly connected to both top sides of one side of the fixing frame, a support arm is rotatably connected to the center of one side of the two connecting pages, a support plate is rotatably connected to the bottom of the two support arms, and a plurality of connecting holes are provided on the surface of the support plate.
[0007] The technical effects achieved by adopting the above solution are: the support arm provides stable support for the fixed frame, thereby increasing the support strength; and the support plate increases the support area at the bottom, thereby improving the stability of the support.
[0008] Preferably, in any of the above embodiments, the length of the support arm is greater than the height of the fixed frame, the length of the support plate is adapted to the width of the fixed frame, and a plurality of the connecting holes are evenly opened in the middle of the top surface of the support plate.
[0009] The technical effect achieved by adopting the above solution is that the support width of the support plate can be matched with the width of the fixed frame, thereby improving the stability of the support.
[0010] Preferably, in any of the above schemes, the length of the shielding blade plate is adapted to the height of the inner wall of the fixed frame, the edges of the shielding blade plates overlap each other, and the distribution length of the shielding blade plates is adapted to the width of the inner wall of the fixed frame.
[0011] The technical effect achieved by adopting the above solution is that the shielding blade plate can completely cover the inner wall of the fixed frame, forming a barrier wall.
[0012] Preferably, in any of the above schemes, the distance between the first connecting shaft and the second connecting shaft at the outermost edge of the plurality of shielding blades after they are closed is greater than the length of the tension spring after it has fully contracted and returned to its original position.
[0013] The technical effect achieved by adopting the above solution is that the tension spring can be tightened to connect the lug, thereby achieving tight closure of several shielding blades.
[0014] This utility model has the following advantages: 1. This anti-tipping construction fence, under normal conditions, uses several shielding blades. When pulled by tension springs, the outermost connecting lug is pulled to one side, and then through a linkage rod, several connecting lugs are pulled to one side simultaneously. This causes several rotating shafts to rotate synchronously, so that the shielding blades press against each other to form a shielding wall. In windy weather, the huge wind pressure can push several shielding blades open, creating a connection between the inside and outside, thereby allowing airflow, reducing the obstruction area, reducing the impact of strong winds, and improving the anti-tipping effect.
[0015] 2. This anti-tipping construction fence uses fixing ears to firmly fix the fixing frame to the ground, and then uses several connecting holes to fix the support plate to the ground on one side of the fixing frame. The support arm can provide stable support for the fixing frame and improve the support strength. The support plate can increase the support area at the bottom and improve the stability of the support. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0019] like Figures 1 to 3 As shown, a construction site fence designed to prevent tipping includes a fixed frame 1. Several rotating shafts 2 are rotatably connected to the center of the inner wall of the fixed frame 1. Each rotating shaft 2 has a shielding blade 3 fixedly connected to its outer wall. The tops of the rotating shafts 2 extend through the top surface of the fixed frame 1 and are fixedly connected to connecting ears 4. A first connecting shaft 5 is fixedly connected to the center of the edge of the top surface of the connecting ear 4 away from the rotating shaft 2. A linkage rod 6 is rotatably connected to the outer walls of the first connecting shafts 5. A shielding plate 7 is fixedly connected to one edge of the top surface of the fixed frame 1. A supporting ear 8 is fixedly connected to one edge of the shielding plate 7. A second connecting shaft 9 is fixedly connected to the center of the top surface of the supporting ear 8. A tension spring 10 is fixedly connected to the outer wall of the second connecting shaft 9 and the outermost edge of the first connecting shaft 5. When the shielding blades 3 are opened, the tension spring is pulled open.
[0020] As an optional technical solution of this utility model, fixing ears 15 are fixedly connected to both bottom sides of the fixed frame 1. A fixing hole is opened on one side of the fixing ears 15. Connecting pages 11 are fixedly connected to both sides of the top side of the fixed frame 1. Support arms 12 are rotatably connected to the center of one side of the two connecting pages 11. Support plates 13 are rotatably connected to the bottom of the two support arms 12. Several connecting holes 14 are opened on the surface of the support plate 13. The fixed frame 1 is firmly fixed to the ground by the fixing ears 15. Then, the support plate 13 is fixed to the ground on one side of the fixed frame 1 by the several connecting holes 14. The support arms 12 can achieve stable support for the fixed frame 1 and improve the support strength. The support plate 13 can increase the support area at the bottom and improve the stability of the support.
[0021] As an optional technical solution of this utility model, the length of the support arm 12 is greater than the height of the fixed frame 1, the length of the support plate 13 is adapted to the width of the fixed frame 1, and a number of connecting holes 14 are evenly opened in the middle of the top surface of the support plate 13, so that the support width of the support plate 13 matches the width of the fixed frame 1, thereby improving the stability of the support.
[0022] As an optional technical solution of this utility model, the length of the shielding blade plate 3 is adapted to the height of the inner wall of the fixed frame 1, the edges of several shielding blade plates 3 overlap each other, and the distribution length of several shielding blade plates 3 is adapted to the width of the inner wall of the fixed frame 1, so that the shielding blade plate 3 can completely shield the inner wall of the fixed frame 1 and form a barrier wall.
[0023] As an optional technical solution of this utility model, after the several blocking blade plates 3 are closed, the distance between the first connecting shaft 5 and the second connecting shaft 9 at the outermost edge is greater than the length of the tension spring 10 after it is fully contracted and reset, so that the tension spring 10 can tighten the connecting lug 4 and realize the tight closure of the several blocking blade plates 3.
[0024] The following steps are required when using this anti-tipping construction fence: 1) When the shielding blades 3 are in normal condition, the outermost connecting lug 4 can be pulled to one side by the tension spring 10. Then, the connecting rod 6 drives the connecting lugs 4 to be pulled to one side synchronously, thereby driving the shafts 2 to rotate synchronously, so that the shielding blades 3 press against each other to form a shielding wall. 2) When encountering strong winds, the huge wind pressure can push open several blocking blades 3, forming a connection between the inside and outside, thereby allowing airflow, reducing the obstruction area, and thus reducing the impact of strong winds. 3) The fixed frame 1 is firmly fixed to the ground by the fixed ear 15, and then the support plate 13 is fixed to the ground on one side of the fixed frame 1 by several connecting holes 14. The support arm 12 can provide stable support for the fixed frame 1 and improve the support strength. The support plate 13 can increase the support area at the bottom and improve the stability of the support.
[0025] In summary, under normal conditions, the outermost connecting lug 4 of the several shielding blades 3 can be pulled to one side by the tension spring 10. Then, the connecting rod 6 drives several connecting lugs 4 to be pulled to one side synchronously, thereby driving several rotating shafts 2 to rotate synchronously. This causes the several shielding blades 3 to press against each other, forming a shielding wall. In windy weather, the huge wind pressure can push the shielding blades 3 open, forming a connection between the inside and outside, thereby allowing airflow, reducing the obstruction area, reducing the impact of strong winds, and improving the anti-collapse effect. The fixing lug 15 is used to firmly fix the fixing frame 1 to the ground, and then the supporting plate 13 is fixed to the ground on one side of the fixing frame 1 through several connecting holes 14. The supporting arm 12 can provide stable support for the fixing frame 1, improving the support strength. The supporting plate 13 can increase the support area at the bottom and improve the stability of the support.
