Example Embodiment

[0020] refer to figure 1 , figure 2 , image 3 , the box body 3 and the box cover 1 of the plastic waste bin are connected by a hinge shaft 2, and a buffer mechanism to prevent the box cover from hitting the box body is installed at the junction of the box body and the box cover. As the first embodiment of the buffer mechanism, the hinge shaft The tail end of 2 is pre-buried in the box cover so that it can rotate with the box cover, the damping cylinder 4 is pre-buried in the upper edge of the box body, and a damping member 5 in the shape of a bolt is placed in the damping cylinder 4, and the top surface of the nut body is It can be screwed with the top of the hinge shaft. The thickness of the bottom wall of the damping cylinder 4 is 1-2 times the thickness of the side wall. The bottom wall has a central hole for the top of the hinge shaft 2 to extend into. To cooperate, install a limit circlip 8 on the hinge shaft at the inner and outer positions of the bottom wall of the ...

Abstract

The invention relates to a dustbin capable of closing slowly. A box body is connected with a box cover by a hinged shaft. A buffer mechanism is arranged at the joint of the box body and the box cover. In the structure of the buffer mechanism, the hinged shaft rotates along with the box cover and the top end of the hinged shaft is in screwed connection with a damping piece in a damping cylinder, and the outer diameter of a spiral spring is slightly smaller than the inner diameter of the damping cylinder; or a torsional spring is sleeved at the hinged shaft between the box body and the box cover, one end of the torsional spring is blocked on the box cover while the other end is locked on the box body, and the inner diameter of the spiral part of the torsional spring is slightly greater than the outer diameter of the hinged shaft; or an elastic damping wedge is fixed on the inner top surface of the box cover, corresponding to the upper edge of the box body, the upper end surface at the upper edge of the box body is made into a concave arc-shaped surface, and the wedge tail of the elastic damping wedge is fixed on the inner top surface of the box cover. The buffer mechanism has the damping force so that the box cover generates slow braking effect in process of falling to close, thereby avoiding vibration and noise generated by rapid collision of the box cover with the upper edge of the box body under effect of gravity and inertia force. And the dustbin has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to a dustbin, in particular to an improvement of the lid closure structure of a dustbin used in public places. Background technique [0002] The trash bins used in public places are generally larger plastic trash bins and metal trash bins. In these existing dustbins, the box body and the box cover are connected by an ordinary hinge mechanism. When the box cover is lowered, due to the potential energy released by the self-weight, a large impact sound will be generated when the box cover contacts the edge of the box body. And it disturbs people's peace, especially the metal box cover, which may even pinch people's hands occasionally; for the plastic box cover, this kind of impact for a long time will also cause the plastic to age prematurely and break. Aiming at this problem, Chinese patent 200720051651.9 introduced a solution, using the air pressure and friction in the piston chamber to make the piston connecting rod move upward ...
