Description

Counterweight type dustbin cover structure and pedal opening type dustbin

Technical Field

The utility model relates to a box cover structure of a dustbin, in particular to a counterweight type box cover structure and a pedal opening type dustbin.

Background

Typical residential or outdoor waste bins are large and have a lid. The lid is normally closed because of the need to protect against water and the emission of odors from the waste. When the garbage is put into the garbage can every time, a user needs to forcibly lift the box cover, so that great force is needed, and the operation is inconvenient. Therefore, a plurality of manufacturers produce the dustbin with the pedal function, and convenience is brought to the operation of users. However, due to the structural design, most of the pedal-type garbage bins need to be stepped on with large force during operation, after the pedal-type garbage bins are stepped on, the gravity center shifts, the stress is reduced, the pedal-type garbage bins are initially not moved, and once the pedal-type garbage bins are stepped on, the bin covers can be quickly lifted up, certain trouble is caused to users, and the reason is that the weight of the bin covers is large. Therefore, the inventor searches a batch of patent documents according to a search keyword 'name ═ (garbage AND (bin or barrel)) AND name, abstract, claim ═ (labor saving (weight reduction or easy operation or labor saving) AND (pedal or foot stepping) AND garbage AND (bin or barrel))', but does not find a structure which can fall on an actual product. And most are theoretically assumed.

Therefore, the inventor of the present invention has considered that it is necessary to redesign the structure of the lid so as to reduce the handling strength of the user when opening the lid, and to allow easy handling by the elderly and young children.
