[0001] This utility model relates to the field of ladder technology, specifically to a safety reinforcement double support rod that enhances the stability of a ladder. Background Technology
[0002] During construction, when quality inspections are required on high walls, construction ladders are often used as climbing tools. However, existing single-frame construction ladders, when used against walls, are prone to swaying and instability due to the lack of stabilizing mechanisms. This poses a significant safety hazard when used for single-sided or single-sided support.
[0003] A ladder stabilizer for stabilizing a ladder, disclosed in CN1914402A, includes an arm component connected to the ladder, the arm component comprising a body, legs, and feet; the legs are telescopically movable relative to the body; the feet are connected to adjacent leg ends and are movable relative to the legs; and a bracket connected to the arm component and movable to the ladder. Traditional ladders or support equipment often use single-plane fasteners or simple clips as the bottom fixing components. They are usually placed directly on the ladder steps for reinforcement and support. This method is prone to loosening under vibration, resulting in unstable anchor points in the support system and easy displacement. Utility Model Content
[0004] The purpose of this utility model is to solve the above-mentioned problems by providing a safety-reinforced double support rod that enhances the stability of the ladder and overcomes the defects of the prior art, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a safety reinforcement double support rod to enhance the stability of a ladder, including a support rod structure. One end of the support rod structure is provided with a locking structure that connects to the ladder, and the other end of the support rod structure is provided with an anti-slip sleeve structure that abuts against the wall. The locking structure includes a fixed buckle plate and a movable buckle plate, and a locking chamber is formed between the fixed buckle plate and the movable buckle plate. The fixed buckle plate and the movable buckle plate are detachably connected to each other and locked together by the locking structure.
