Description

TECHNICAL FIELD

[0001] The utility model relates to power cabinet carrying technical field, concretely is a kind of power cabinet tow handle self-locking device. BACKGROUND

[0002] The carrying of power cabinet usually needs to use appropriate tools and methods, for example, a forklift can be used to lift the power cabinet off the pallet and place it on the ground, or by coordinating the actions of each mechanism, the continuous actions of holding, pushing, forking, righting, lifting and carrying the power distribution cabinet are realized, and the carrying efficiency and stability are improved.

[0003] For example, the patent with publication number CN218893006U discloses a carrying device, which includes a support part, an air bag part, a suction cup part and a support part. The support part includes a bottom support part and a top support part, and a cavity is formed between the bottom support part and the top support part. A first roller is provided on the bottom support part, and the top support part is used to place the object to be carried. The support part is placed in the gap between the object to be carried and the ground. The air bag part is provided in the cavity. The air bag part is inflated to make the top support part move upward relative to the bottom support part. The air bag part is deflated to make the top support part move downward relative to the bottom support part. The suction cup part is used to adsorb the object to be carried. The support part and the suction cup part are provided on the support part. The patent adsorbs and connects the object to be carried by the suction cup, and then drives the top support part to rise by inflating the air bag part, so as to lift the object to be carried off the ground.
