Description

Technical Field

[0001] The utility model belongs to the technical field of ladders, and particularly relates to a ladder foot pedal locking structure. Background Art

[0002] When a folding ladder is unfolded, the top pedal needs to be locked with the ladder frame before the pedal can be locked in the unfolded state. The existing pedal locking structure generally uses a snap-fit ​​piece to snap the top pedal onto the ladder frame. The snap-fit ​​piece is generally an upper and lower snap-fit ​​structure. When stepped on, it is easily unlocked by external force, causing the pedal assembly to be contracted, resulting in reduced safety performance. Utility Model Content

[0003] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a ladder foot pedal locking structure to solve the problems mentioned in the background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] Preferably, a telescopic groove is provided on the top pedal, the clamping component includes a component body, sliding bars are provided on both sides of the component body, sliding grooves are provided on the inner walls on both sides of the telescopic groove, and the component body is slidably connected in the telescopic groove through the sliding bars and the sliding grooves.

[0007] Preferably, a second limiting groove is provided on the component body, the second limiting groove is close to the front end of the component body and passes through the component body laterally, a connecting rod is provided in the telescopic groove, the connecting rod passes through the second limiting groove, and the second limiting groove is used to realize the limitation of the component body when it is telescopically extended in the telescopic groove.

[0008] Preferably, the telescopic assembly includes a limiting column arranged on the inner end of the telescopic slot, and a limiting slot arranged on the rear end of the component body, and also includes a spring component, one end of which abuts against the limiting column and the other end abuts against the limiting slot.

[0009] Preferably, a connecting plate is provided at the bottom of the component body, and the connecting plate extends downward and bends to form the hook-shaped clamping portion.

[0010] Preferably, after the top pedal is unfolded, the locking cross bar passes through the telescopic slot.

[0011] Preferably, the rear end of the component body protrudes from the outer side of the top pedal to facilitate operation and pressing.

[0012] Preferably, a mounting groove is formed on the bottom surface of the top pedal, and windows are provided on the top and outer side surface of the top pedal, and the windows are connected with the mounting groove to form the telescopic groove.

[0013] When in use, press the body of the component inwards and buckle it on the locking cross bar. Then release the pressure and the spring component will allow the clamping part to be clamped on the locking cross bar. Since unlocking requires applying a force in the radial direction of the top pedal when clamped, the brake will not become unhooked due to excessive force during pedaling, making it safer to use.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The present application sets a telescopic clamping piece along the radial direction of the top pedal to achieve locking of the top pedal and the transverse locking rod. When in use, decoupling will not occur, and the use is safer. BRIEF DESCRIPTION OF THE DRAWINGS
