Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a footboard with a locking structure for scaffolding. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. Footboards, designed for workers to step on, are disclosed in CN219753935U. This discloses a stable scaffolding footboard, relating to the field of scaffolding technology. It includes a footboard body, an overlapping groove, and a cold-pressing groove. The footboard body has installation openings on both sides, with fixing blocks on the inner walls of the installation openings. Fixing ears are provided on both sides of the bottom of the footboard body. A clamping plate is provided on the outer wall of the footboard body near the fixing ears. A chain is fixedly connected to the outer wall of the fixing ears. A limit ring is provided at the end of the chain away from the fixing blocks. The limit ring can be respectively fitted onto the clamping plate and the fixing blocks. While this design offers significant advantages, each disassembly requires separating the chain from the fixing ears and then separating another chain from the fixing ears on the other side, increasing the labor intensity of individual disassembly.

[0003] Therefore, we propose a footboard with a locking structure for scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a footboard with a locking structure for scaffolding, in order to solve the problem mentioned in the background art that each time the chain is disassembled, it is necessary to separate the chain from the fixing lug and then separate the other chain from the fixing lug on the other side, thereby increasing the labor intensity of individual disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a footboard with a locking structure for scaffolding, comprising a linkage shaft at the bottom of the footboard, gears at both ends of the linkage shaft, each gear being connected to a linkage rod, linkage cylinders on both sides of the linkage shaft, the linkage cylinders being fixedly connected to a connecting shaft, one end of a pull rope being fixedly connected to the linkage cylinder, and a limiting plate being fixedly connected to the other end of the pull rope, one side of the limiting plate tightly pressing a spring, and a locking plate on the other side of the limiting plate, the limiting plate being slidably connected to a base, and a sliding rod being provided inside the base.

[0006] Preferably, the bottom of the pedal is fixedly connected to two bases, and the bases are slidably connected to a linkage rod.

[0007] Preferably, the linkage rod has teeth, and the teeth are connected to a gear.

[0008] Preferably, the linkage shaft is provided with a left gear for clockwise rotation, and the left gear is connected to the linkage shaft.

[0009] Preferably, the linkage shaft is provided with a right gear for counterclockwise rotation, and the right gear is connected to the linkage shaft.

[0010] Preferably, the linkage shaft has a pedal center section, and the linkage shaft is rotatably connected to the pedal.

[0011] Preferably, the top of the limiting plate is provided with a connecting ear, and the connecting ear is fixedly connected to the other end of the pull rope.

[0012] Preferably, the locking plate has a groove in the middle, and the groove is slidably connected to the connecting ear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a linkage shaft at the bottom of the pedal, with gears at both ends. Each gear is connected to a linkage rod. Linkage cylinders are located on both sides of the linkage shaft, serving not only as fixed connections to the connecting shaft but also as the starting point for the pull rope. The other end of the pull rope is fixedly connected to a limiting plate. One side of the limiting plate tightly presses against a spring, while the other side has a locking plate rotatably connected to the base. When the pedal needs to be disassembled, the operator only needs to pull one of the linkage rods. Through the transmission of the linkage cylinders, connecting shaft, and pull rope, the limiting plate slides on the base, compressing the spring and releasing the locking plate. This reduces the operator's workload and improves disassembly efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1-3 The illustration shows a footboard with a locking structure for scaffolding. It includes a footboard 1 with a linkage shaft 2 at its bottom. Both ends of the linkage shaft 2 have gears 3, each gear 3 drivingly connecting to a linkage rod 4. Linkage cylinders 5 are located on both sides of the linkage shaft 2, and are fixedly connected to a connecting shaft 6. One end of a pull rope 7 is fixedly connected to the linkage cylinder 5, and the other end of the pull rope 7 is fixedly connected to a limiting plate 8. One side of the limiting plate 8 tightly presses against a spring 9, and the other side has a locking plate 10. The limiting plate 8 is slidably connected to a base 11, and a sliding rod 12 is located inside the base 11. This invention utilizes the linkage shaft at the bottom of the footboard, with both ends of the linkage shaft... Each component is equipped with gears, and each gear is connected to a linkage rod. Linkage cylinders are installed on both sides of the linkage shaft. The linkage cylinders are not only fixedly connected to the connecting shaft, but also serve as the starting point of the pull rope. The other end of the pull rope is fixedly connected to the limit plate. One side of the limit plate tightly presses against the spring, and the other side is equipped with a locking plate. The locking plate is rotatably connected to the base. When the pedal needs to be removed, the operator only needs to pull the linkage rod on one side. Through the transmission of the linkage cylinder, connecting shaft, and pull rope, the limit plate slides on the base and compresses the spring, thus releasing the locking plate from its locked state. This reduces the operator's labor intensity and improves the disassembly efficiency.

[0021] Furthermore, two bases 11 are fixedly connected to the bottom of the pedal 1, and the bases 11 are slidably connected to the linkage rod 4. The two bases are fixedly connected to the bottom of the pedal, and both bases are slidably connected to the linkage rod, so that the linkage rod can slide smoothly inside the base and ensure the stability of the movement trajectory.

[0022] Furthermore, the linkage rod 4 has a toothed plate 401, which is connected to the gear 3. The toothed plate on the linkage rod is connected to the gear, ensuring good meshing with the gear. At the same time, the rotation of the gear drives the linkage rod to move linearly.

[0023] Furthermore, the linkage shaft 2 is equipped with a left gear 201 for clockwise rotation. The left gear 201 is connected to the connecting shaft 6. By specially designing a left gear for clockwise rotation on the linkage shaft and connecting it to the connecting shaft, it is ensured that when the linkage shaft is subjected to driving force, the left gear can drive the connecting shaft to rotate in its specific rotation direction.

[0024] Furthermore, the linkage shaft 2 is equipped with a right gear 202 for counterclockwise rotation. The right gear 202 is connected to the connecting shaft 6. By specially designing a right gear for counterclockwise rotation on the linkage shaft and connecting it to the connecting shaft, the right gear can drive the connecting shaft on the other side to rotate in its specific rotation direction when the linkage shaft is subjected to a driving force in a specific direction.

[0025] Furthermore, the linkage shaft 2 is located in the middle of the pedal 1. The linkage shaft 2 is rotatably connected to the pedal 1. By setting the linkage shaft in the middle of the pedal, the rotational connection between the linkage shaft and the pedal is realized. The middle mounting allows the linkage shaft to better withstand and transmit the force and movement from the pedal, while maintaining a tight connection between the two, thereby ensuring the accuracy and reliability of the transmission.

[0026] Furthermore, the top of the limiting plate 8 is provided with a connecting ear 801, which is used to fix the other end of the pull rope 7. The connecting ear is specially designed on the top of the limiting plate, and the other end of the pull rope is fixedly connected to the connecting ear to ensure that the limiting plate and the end of the pull rope can be tightly and firmly connected together, thereby preventing easy loosening or falling off during the movement and ensuring normal operation.

[0027] Furthermore, a groove is provided in the middle of the locking plate 10, and the groove is slidably connected to the connecting ear 801. By specially opening a groove in the middle of the locking plate and realizing the sliding connection between the groove and the connecting ear, it is ensured that the connecting ear can move freely in the groove and maintain a stable connection with the locking plate.

[0028] In this solution, the workflow is as follows: When dismantling is required, the worker pulls the linkage rod 4, which in turn drives the gear 3 to rotate. During the rotation of the gear 3, the linkage shaft 2 drives the connecting shaft 6 to rotate.

[0029] The connecting shaft 6 is fixed with the linkage cylinder 5, and the linkage cylinder 5 is fixedly connected with the pull rope 7. During the rotation of the connecting shaft 6, the pull rope 7 is wound up, thereby driving the limit plate 8 to slide. During the sliding connection process of the limit plate 8, the spring 9 will be squeezed. When the limit plate 8 moves to the moving position, the locking plate 10 will automatically droop.
