[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable scaffold for construction engineering, comprising a support plate and a support frame rotatably mounted at its bottom, with a connecting mechanism rotatably connected between the two support frames. The connecting mechanism includes a reinforcing rod, a first rotating rod, and a second rotating rod. The reinforcing rod is fixedly mounted on the inner side of the support frame. A connecting plate is rotatably connected between the first rotating rod and the second rotating rod. The first rotating rod and the second rotating rod are respectively rotatably connected to the two reinforcing rods.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a portable scaffold for construction engineering, including a support plate 1 and a support frame 2 rotatably mounted on its bottom. A connecting mechanism 3 is rotatably connected between the two support frames 2. The connecting mechanism 3 includes a reinforcing rod 31, a first rotating rod 32, and a second rotating rod 33. The reinforcing rod 31 is fixedly installed on the inner side of the support frame 2. A connecting piece 35 is rotatably connected between the first rotating rod 32 and the second rotating rod 33. The first rotating rod 32 and the second rotating rod 33 are respectively rotatably connected to the two reinforcing rods 31. Connecting gears 37 are symmetrically rotatably mounted on the inner side of the connecting piece 35. The two connecting gears 37 are located at both ends of the connecting piece 35 and mesh with each other. One connecting gear 37 is located on the inner side of the first rotating rod 32, and the other connecting gear 37 is located on the inner side of the second rotating rod 33. A limiting plate 36 is fixedly installed at the end of the second rotating rod 33. The limiting plate 36 is located on the upper surface of the first rotating rod 32 and the second rotating rod 33.

[0022] The specific setup and function of this embodiment are described in detail below. The overall support is achieved by the support frame 2 rotatably mounted at the bottom of the support plate 1. The connecting mechanism 3 between the two support frames 2 plays a role in linkage and reinforcement. The reinforcing rod 31 is fixed to the inner side of the support frame 2, providing a basic connection point. The first rotating rod 32 and the second rotating rod 33 are rotatably connected to the two reinforcing rods 31 respectively, and the two are rotatably connected by a connecting piece 35. Two connecting gears 37, symmetrically rotatably mounted on the inner side of the connecting piece 35, are located at both ends and mesh with each other, respectively embedded inside the first rotating rod 32 and the second rotating rod 33. This ensures that the first rotating rod 32 and the second rotating rod 33 rotate synchronously through gear meshing. Simultaneously, the second... The limiting plate 36 at the end of the rotating rod 33 is located on the upper surface of both, limiting the rotation range. Utilizing the rotational connection between the first rotating rod 32, the second rotating rod 33 and the connecting piece 35 in the connecting mechanism 3, and the meshing transmission of the connecting gear 37, the two support frames 2 can be simultaneously unfolded or folded, improving operational convenience and portability. The reinforcing rod 31 enhances the stability of the connection between the support frame 2 and the rotating rod, and the meshing of the connecting gear 37 ensures rotational synchronization, avoiding uneven force on the support frame 2. The limiting plate 36 prevents excessive rotation that could cause structural damage. While ensuring the support stability of the support plate 1, it also takes into account the portability and structural strength of the scaffolding, making it suitable for the mobile operation needs in construction engineering.

[0023] Example 2: Figure 3 and Figure 4 As shown, the second rotating rod 33 has a cavity 311 inside. A gear 310 is slidably connected to the inside of the second rotating rod 33 through the cavity 311. A driven gear 38 is fixedly installed on one side of the gear 37 connected to the inner side of the reinforcing rod 31. The gear 310 is meshed with the driven gear 38. A control lever 34 is rotatably installed inside the second rotating rod 33. The control lever 34 passes through another second rotating rod 33. A transmission gear 39 is fixedly installed on the rod body of the control lever 34. The transmission gear 39 is meshed with the gear 310.

[0024] The overall effect of this embodiment is that by rotating the control lever 34, the transmission gear 39 fixed on its body is driven to rotate. The transmission gear 39 meshes with the rack 310, causing the rack 310 to slide in the cavity 311 inside the second rotating rod 33. The sliding of the rack 310 drives the driven gear 38 meshing with it to rotate. The driven gear 38 is fixedly connected to the connecting gear 37 on the inner side of the reinforcing rod 31, thereby causing the connecting gear 37 to rotate. Since the two connecting gears 37 mesh with each other, the first rotating rod 32 and the second rotating rod 33 are synchronously linked, driving the two support frames 2 to unfold or fold synchronously. This is achieved by utilizing the control lever 34, the transmission gear 39, and the rack 310. 10. The multi-stage transmission system composed of driven gear 38 and connecting gear 37 transforms the rotation of a single control lever 34 into the synchronous action of two support frames 2, making operation simple and efficient. The cavity 311 provides sliding space for the rack 310, making the structure compact and reasonable. The reinforcing rod 31 enhances the stability of the connection between the support frame 2 and the rotating rod. The meshing of driven gear 38 and rack 310, as well as the meshing between connecting gear 37, ensures the accuracy and synchronization of the transmission, avoids uneven force on the support frame 2, and further improves the convenience of scaffolding deployment and folding while ensuring the support stability of the support plate 1, making it suitable for the needs of rapid construction and mobile operation in building engineering.

[0025] The operating method and working principle of this device are as follows: When unfolding the scaffolding, rotate the control lever 34 that passes through the second rotating rod 33. The control lever 34 drives the transmission gear 39 on the rod to rotate. The transmission gear 39 meshes with the rack 310, causing the rack 310 to slide in the cavity 311. The rack 310 drives the driven gear 38 to rotate. The driven gear 38 drives the inner connecting gear 37 of the reinforcing rod 31, which is fixed to it, to rotate. Since the two connecting gears 37 mesh with each other, the first rotating rod 32 and the second rotating rod 33 are synchronously linked, driving the two supports... The frame 2 unfolds synchronously until the limiting plate 36 at the end of the second rotating rod 33 restricts the rotation range of the first rotating rod 32 and the second rotating rod 33. At this time, the scaffolding is unfolded into place, and the reinforcing rod 31 enhances the stability of the support frame 2. The support plate 1 can be used for construction engineering operations. When folding the scaffolding, the control lever 34 is rotated in the opposite direction. Through the transmission gear 39, the rack 310, the driven gear 38, and the connecting gear 37, the first rotating rod 32 and the second rotating rod 33 rotate synchronously in the opposite direction, driving the two support frames 2 to fold synchronously, thus completing the storage of the scaffolding.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
