Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a construction safety scaffolding structure with a self-locking function. Background Technology

[0002] Current construction scaffolding mainly consists of steel pipe frames and platform panels. The platform panels are attached to the horizontal pipes of the steel pipe frame via clasps. These clasps typically have a semi-circular opening structure, which is used for installation and dismantling operations.

[0003] However, traditional hooks and loops rely solely on their own weight for simple fastening and do not have a locking structure. When construction workers stand at the long edge of the platform, the hooks that are far from the standing position tend to lift up due to the shift in the center of gravity, causing the openings to separate from the horizontal tubes of the steel pipe frame, resulting in a partial loss of restraint on the platform.

[0004] The aforementioned warping phenomenon may cause the platform slab to overturn or tilt, posing a significant construction safety hazard. Therefore, there is an urgent need for a scaffolding structure that can prevent the platform slab from accidentally warping and achieve a self-locking function. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a construction safety scaffold structure with a self-locking function. The first arc-shaped buckle automatically rotates inward under gravity and engages with the steel pipe frame, achieving a stable connection of the platform board. When construction workers stand at the edge of the platform board, the first arc-shaped buckle firmly locks the steel pipe frame, preventing the platform board from tipping over or tilting, thereby improving construction safety.

[0006] The technical solution adopted to solve the above technical problems is: a construction safety scaffold structure with self-locking function, including a steel pipe frame, a platform plate, a first arc-shaped buckle and a connecting rod. The platform plate is rotatably connected to both sides of its short side with a first arc-shaped buckle. After the first arc-shaped buckle is engaged, it wraps around and locks the lower side of the horizontal pipe of the steel pipe frame, preventing the platform plate from coming out. The connecting rod connects two adjacent first arc-shaped buckles. The connecting rod is rotatably connected to the side of the platform plate, and the two first arc-shaped buckles rotate synchronously through the connecting rod.

[0007] Furthermore, it also includes a lock block, a lock hole, and a spring pin. A circular lock block is coaxially connected to the connecting rod. A lock hole is opened on the side wall of the lock block. A spring pin is connected to the short edge of the platform plate. The spring pin cooperates with the lock hole.

[0008] Furthermore, it also includes a second arc-shaped buckle and a gear. The platform plate is rotatably connected to both sides of its short side. After the second arc-shaped buckle is engaged, it wraps around and locks the lower side of the horizontal tube of the steel pipe frame, preventing the platform plate from coming out. The second arc-shaped buckle and the first arc-shaped buckle are integrally connected to a gear. The first arc-shaped buckle and the second arc-shaped buckle are linked by the gear meshing. The first arc-shaped buckle and the second arc-shaped buckle form an interlocking structure and are locked on the steel pipe frame.

[0009] Furthermore, it also includes a torsion spring connected to the connecting rod, the torsion spring providing torsional elasticity to the connecting rod.

[0010] Furthermore, it also includes a pull rod, which is connected to the first arc-shaped buckle.

[0011] The beneficial effects of this utility model are as follows: By setting a connecting rod, the first arc-shaped buckles on both sides of the short side of the platform plate can rotate synchronously. When installing the platform plate, the connecting rod drives the first arc-shaped buckles to open outward. At this time, the spring pin is inserted into the locking hole on the side wall of the locking block, forming a temporary lock on the connecting rod and the locking block, keeping the first arc-shaped buckles in the open state. After the platform plate is placed on the steel pipe frame, the spring pin is pulled to release the lock, and the first arc-shaped buckles automatically rotate inward under the action of gravity and fasten to the steel pipe frame, realizing a stable connection of the platform plate. When the construction personnel stand at the edge of the platform plate, the first arc-shaped buckles firmly lock the steel pipe frame, preventing the platform plate from tipping over or tilting, thereby improving construction safety.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-3As shown in the figure, this embodiment provides a construction safety scaffold structure with self-locking function, including a steel pipe frame 1, a platform plate 2, a first arc-shaped buckle 3, and a connecting rod 4. The platform plate 2 is rotatably connected to both sides of its short side with the first arc-shaped buckle 3. After the first arc-shaped buckle 3 is fastened, it wraps around and locks to the lower side of the horizontal pipe of the steel pipe frame 1, preventing the platform plate 2 from coming out. The connecting rod 4 connects two adjacent first arc-shaped buckles 3. The connecting rod 4 is rotatably connected to the side of the platform plate 2, and the two first arc-shaped buckles 3 rotate synchronously through the connecting rod 4.

[0018] It also includes a locking block 5, a locking hole 6 and a spring pin 7. A circular locking block 5 is coaxially connected to the connecting rod 4. The locking block 5 has a locking hole 6 on its side wall. A spring pin 7 is connected to the short edge of the platform plate 2. The spring pin 7 cooperates with the locking hole 6.

[0019] In the above embodiments, by setting the connecting rod 4, the first arc-shaped buckles 3 on both sides of the short side of the platform plate 2 can rotate synchronously. When installing the platform plate 2, the connecting rod 4 drives the first arc-shaped buckles 3 to open outward. At this time, the spring pin 7 is inserted into the lock hole 6 on the side wall of the locking block 5, forming a temporary lock on the connecting rod 4 and the locking block 5, keeping the first arc-shaped buckles 3 in the open state. After the platform plate 2 is placed on the steel pipe frame 1, the spring pin 7 is pulled to release the lock. The first arc-shaped buckles 3 automatically rotate inward under the action of gravity and fasten to the steel pipe frame 1, realizing the stable connection of the platform plate 2. When the construction personnel stand at the edge of the platform plate 2, the first arc-shaped buckles 3 firmly lock the steel pipe frame 1, preventing the platform plate 2 from tipping over or tilting, thereby improving construction safety.

[0020] Specifically, it also includes a second arc-shaped buckle 8 and a gear 9. The platform plate 2 is rotatably connected to both sides of its short side with a second arc-shaped buckle 8. After the second arc-shaped buckle 8 is engaged, it wraps around and locks the lower side of the horizontal tube of the steel pipe frame 1, preventing the platform plate 2 from coming out. The second arc-shaped buckle 8 and the first arc-shaped buckle 3 are integrally connected with a gear 9. Correspondingly, the first arc-shaped buckle 3 and the second arc-shaped buckle 8 are linked by the gear 9. The first arc-shaped buckle 3 and the second arc-shaped buckle 8 form an interlocking structure and are locked on the steel pipe frame 1.

[0021] In the above embodiments, the second arc-shaped buckle 8 is linked with the first arc-shaped buckle 3 through the gear 9 to form an interlocking structure, which further wraps the lower side of the horizontal tube of the steel pipe frame 1, preventing the platform plate 2 from coming off under the action of external force, and significantly enhancing the resistance to pull-out.

[0022] Specifically, it also includes a torsion spring 10, which is connected to the connecting rod 4 and provides torsional elasticity to the connecting rod 4.

[0023] In the above embodiments, a torsion spring 10 is further provided to provide a reset torsional force for the connecting rod 4, ensuring that the arc-shaped buckle can be quickly and stably locked in place after the lock is released, thereby improving the self-locking response speed and reliability.

[0024] Specifically, it also includes a pull rod 11, which is connected to the first arc-shaped buckle 3.

[0025] In the above embodiments, it is convenient for operators to manually pull the first arc-shaped buckle 3 to unlock or install, thus improving the ease of operation.

[0026] The working principle of this utility model is as follows:

[0027] The operator pulls the lever 11, causing the first arc-shaped buckle 3 connected to it to rotate outward. The first arc-shaped buckle 3 drives the other end of the first arc-shaped buckle 3 to rotate synchronously through the connecting rod 4. At the same time, the second arc-shaped buckle 8 is also driven to open outward through the meshing of the gear 9. At this time, the torsion spring 10 on the connecting rod 4 is compressed and stored, and the circular locking block 5 coaxially set on the connecting rod 4 rotates accordingly until the spring pin 7 on the edge of the platform plate 2 springs into the locking hole 6 on the side wall of the locking block 5, completing the temporary locking of the connecting rod 4. At this time, all the arc-shaped buckles are in the open state, which is convenient for the platform plate 2 to be placed.

[0028] Place the platform plate 2 above the horizontal tube of the steel pipe frame 1, so that the horizontal tube is inside the first arc-shaped buckle 3 and the second arc-shaped buckle 8. Then pull the spring pin 7 to disengage it from the locking hole 6. Under the restoring force of the torsion spring 10, the connecting rod 4 rotates in the opposite direction, causing the first arc-shaped buckle 3 and the second arc-shaped buckle 8 to rotate inward synchronously. Since the arc-shaped structure of the first arc-shaped buckle 3 and the second arc-shaped buckle 8 can wrap around the lower side of the horizontal tube, the platform plate 2 cannot come out, thus achieving stable self-locking.

[0029] During disassembly, the operator pulls the lever 11 again, causing the first arc-shaped buckle 3 to rotate outward, which in turn causes all the arc-shaped buckles to open synchronously. When the spring pin 7 springs back into the lock hole 6, the locking state is restored, and all the arc-shaped buckles disengage from the horizontal tube, allowing the platform plate 2 to be lifted upward and removed.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
