Description

Technical Field

[0001] This invention relates to a safety clip for use on pedals, and more particularly to a safety clip structure for pedals that avoids adhesion during hot-dip galvanizing, is easy to peel off, and is easy for personnel to operate. Background Technology

[0002] During construction or repair work on a site, a scaffold is typically erected around the perimeter to form an external connecting structure. This allows users to perform construction and other tasks. To provide a standing workspace, the scaffold is equipped with several footboards 10 for user use; please refer to [link / reference]. Figure 1 and 2 As shown, the existing pedal 10 has a body 11 for creating a standing plane. A hook 12 is provided at the front and rear ends of the pedal 10. The hook 12 has a hook portion 121 for fastening to the work frame. In order to prevent the pedal 10 from falling off the work frame, a fastening piece 122 is pivotally provided on one side of the hook portion 121. After the hook portion 121 is hooked on the work frame, the fastening piece 122 can be moved to limit the work frame between the hook portion 121 and the fastening piece 122, so that the hook 12 cannot be separated from the work frame.

[0003] In existing technology, after the pedal 10 is manufactured, it undergoes a hot-dip galvanizing process to galvanize the entire surface of the pedal (including the hook 12 and the fastener 122), so that the pedal body 11 and the hook 12 can resist corrosion from the external environment and are not easy to rust. However, during hot-dip galvanizing, the pedal 10 is usually placed upright and tilted into the galvanizing tank to achieve an appropriate amount of zinc adhesion. However, because the hook part 121 and the fastener 122 of the hook 12 are in a movable state, during hot-dip galvanizing, the fastener 122 will move closer to the hook part 121 due to its own weight, forming a close fit. After hot-dip galvanizing is completed, the hook part 121 and the fastener 122 may become stuck together due to the influence of the zinc liquid adhesion layer. Therefore, after the hot-dip galvanizing of the pedal 10 is completed, it is necessary to confirm whether the hook part 121 and the fastener 122 can move. If the hook part 121 and the fastener 122 are stuck together, further local processing is required to remove the adhered zinc liquid layer, and it must be ensured that the zinc liquid layer remains on the surface of the hook part 121 and the fastener 122. This process will cause uncertainty in the use of the product, and the processing is relatively cumbersome, requiring more time and cost.

[0004] In addition, when the pedal 10 is placed on the workbench, the hooking portion 121 is buckled on the workbench, and the buckling pieces 122 automatically slide downward due to the weight, so that the hooking portion 121 and the buckling pieces 122 form a partially closed state, the hooking portion 12 cannot be separated from the workbench, and the user cannot be overturned when standing on the pedal 10 to work, and the falling problem cannot occur. When the work is completed and the workbench and the pedal 10 are to be removed, the operator needs to work below the pedal 10, and the buckling pieces 122 provided on the hooking portion 121 of the pedal 10 are flipped upward, so that the hooking portion 121 and the buckling pieces 122 are opened, and the hooking portion 121 and the buckling pieces 122 that originally limit the workbench are converted to an open state, so that the pedal 10 and the workbench can be separated.

[0005] The buckling piece 122 of the prior art pedal 10 is a sheet structure, and when it is flipped up, it can only be flipped upward from the lower end of the buckling piece 122, the area of the force point is small, and it is not easy to flip the buckling piece 122 upward during operation. When the pedal 10 is removed, it also consumes more time and reduces work efficiency. SUMMARY

[0006] An object of the present application is to provide a safe buckling piece structure, which can be spaced apart from the hooking portion and the buckling piece by the provision of a holding portion, so that excessive adhesion of the two during hot-dip galvanizing can be avoided, and the adjustment process and time can be reduced.

[0036] Please refer to Figure 3 , which shows a workbench A provided with a plurality of pedals 20 for a user to step on, each pedal 20 being provided with two safety catches at two ends thereof, so that the pedal is arranged on the workbench A. The body 30 of the pedal 20 has a rectangular plate portion 31, and a frame 32 is wrapped around the periphery of the plate portion 31, the frame 32 having two side frames 321 and two end frames 322.

[0037] Figures 4 to 6The safety buckle structure of the first preferred embodiment of the present application has a hook 40 and a buckle 50. The hook 40 is arranged on the end frame 322 of the body 30 of the pedal 20. The hook 40 has a hooking portion 41 and a base 42, and can be buckled on the workbench A. The rear end of the base 42 is fixed on the end frame 322 of the pedal 20, and the front end of the base 42 forms the hooking portion 41. The hooking portion 41 is an arc-shaped hook portion. One side of the base 42 is provided with two pivot columns 43.

[0038] The buckle 50 is an arc-shaped piece. The buckle 50 is provided with two arc grooves 51 opposite the two pivot columns 43. The periphery of each of the two arc grooves 51 is defined as a groove edge 511. The outer side of the buckle 50 is also defined as an outer periphery 52. The buckle 50 is sleeved on the two pivot columns 43 of the hook 40 through the two arc grooves 51, so that the buckle 50 can slide relative to the hook 40, and can partially close or open the space between the hooking portion 41 and the base 42. The end edge (bottom side) of the buckle 50 is provided with a push block 53. The push block 53 can be used by a user to exert force to pull, so that the buckle 50 can be easily adjusted in position.

[0039] In use, as shown in Figure 3 , the pedal 20 is arranged on the workbench A. The hook 40 hooks the workbench A, and the buckle 50 is moved downward, so that the hooking portion 41 and the buckle 50 sleeve the workbench A, preventing the pedal 20 from falling off. When the pedal 20 is separated from the workbench A, the user can directly pull the push block 53 of the buckle 50, so that the buckle 50 is easily pulled, and the difficulty and time of disassembling the pedal 20 can be reduced.

[0040] Please refer to Figures 4 to 6As shown, the present application sets the top holding part 60 between the hook 40 and the buckle 50 to keep a distance between the hook 40 and the buckle 50; the top holding part 60 of the embodiment is set at the position of the outer periphery 52 of the buckle 50, the buckle 50 is provided with three top holding parts 60, the top holding part 60 is a protrusion formed by stamping, other forming methods of the top holding part can also be used, and the forming method is not limited; the end of the top holding part 60 has a pointed end 61, which can contact or not contact the side surface of the hook 40; when the pedal 20 is subjected to hot-dip galvanizing, the pedal 20 is straightened, so that the buckle 50 can be close to the hook 40 due to its own weight, when the buckle 50 is close, the top holding part 60 provided on the buckle 50 protrudes from the end surface of the buckle 50, so that the pointed end 61 of the top holding part 60 first contacts the side surface of the hook 40, so that the buckle 50 keeps a proper distance from the hook 40, through the distance, the opposite surfaces of the buckle 50 and the hook 40 can be covered by the zinc solution during hot-dip galvanizing, and a good zinc solution adhesion layer can be formed. In addition, because the buckle 50 and the hook 40 have a distance between them, the two are not easy to be adhered by the zinc solution adhesion layer, even if they are adhered, it will only occur on the pointed end 61 of the top holding part 60 and the side surface of the hook 40, the contact area is small, easy to process and remove, and the time and difficulty of subsequent processes can be reduced. Depending on the processing method, the side surface (first side surface) of the buckle 50 can be formed with several protruding top holding parts 60, and the other side surface (second side surface) of the buckle remains flat and has no any recess.

[0041] Please refer to Figure 7 As shown, the second preferred embodiment of the safety buckle provided by the present application has the same main structure as the previous embodiment, the same structure is denoted by the same symbol, and will not be described again, wherein:
