Abstract

The utility model relates to a garbage can, in particular to an elastic buffer structure of a garbage can. A can body and a can cover are connected by a hinge shaft. The elastic buffer structure is characterized in that a part at the inner top surface of the can cover near the hinge shaft and corresponding to the upper edge part at one side of the can body is fixed with an elastic damping wedge; the upper end surface of the upper edge part at one side of the can body, corresponding to the elastic damping wedge, is an arc surface; the tail of the elastic damping wedge is fixed at the top surface inside the can cover; and the tip of the elastic damping wedge clings to and slides and bends along the arc surface when the can cover is falling down to cover the can body. As the buffer structure has damping force, the can cover generates a slowly-braking effect when falling down to cover the can body, so that the can cover can be prevented from rapidly colliding with the upper edge of the can body and then shake and sound caused by rapid collision are avoided; and the elastic buffer structure is simple and low in cost.

Description

A kind of elastic buffer structure of rubbish container

Technical field

The utility model relates to rubbish container, the improvement of the rubbish container covering structure that particularly a kind of public arena is used.

Background technology

The rubbish container that the public arena is used is generally the plastic garbage case and the dustbin of larger volume.Existing these rubbish containers, casing is connected by common linkage with case lid, when the case lid lower cover, because the potential energy effect that deadweight discharges, the moment that case lid contacts with the casing bead can produce the bigger bump sound and disturb people's peacefulness, metal case lid especially, even can crush staff once in a while; For the plastics case lid, long-term this bump also can make the plastics premature aging and breaks.At this problem, Chinese patent 200720051651.9＜a kind of sewage disposer with buffer structure〉introduced a kind of terms of settlement, utilize the effect of piston cavity inner air pressure and friction force, piston rod is slowly moved up, realize slowly covering of case lid.Obviously, this is for the used rubbish container in most of public arenas, environment wet by the rain and burnt by the sun, structure is complexity et out of order too early easily often too, produce and use cost too high.

The utility model content

The purpose of this utility model is to provide a kind of sound that do not knock in use, and is simple in structure, safe in utilization, the life-span is long, has the slow elastic buffer structure that covers the rubbish container of function cheaply.

The technical solution of the utility model is: a kind of elastic buffer structure of rubbish container, casing is connected by hinge with case lid, it is characterized in that at the flexible damping wedge of the cooresponding stationkeeping of case lid inner top surface and position, casing side upper edge near hinge, make cancave cambered surface with upper surface, position, the cooresponding casing side upper edge of elastic damping wedge, the wedge tail of elastic damping wedge is fixed on the case lid inner top surface, and the wedge point is close to when the case lid lower cover and is slided crooked along described cancave cambered surface.

Adopt above-mentioned design, can guarantee under the low-cost prerequisite bump sound that produces by effect of inertia when solving the case lid lower cover effectively.When case lid has just begun to cover, the tip that the damping wedge is thin begins bending and produces damping, the angle that covers is big more, the thickness of damping wedge crooked position is thick more, and dumping force is big more, and the speed that covers is slow more, when case lid arrival covers the position transformation point, the thickest position of damping wedge root still can't continue to be bent under case lid gravity and force of inertia effect, and the setting that case lid promptly stops at casing upper edge retention gap covers on the position, has avoided the bump sound.Described elastic damping wedge is made by silaatic or latex or elastic polyester material, because these material flexibility are big, repeated deflection is difficult for be full of cracks often.

Be installed with cushion at inner top surface away from two jiaos of the case lids of hinge.Its effect is to have deviation when the design of the amount of elasticity of elastic element, or elastic element is aging, causes dumping force to reduce, and cushion plays buffer action, can avoid case lid directly to contact with the casing upper edge and reduces strike note, increases the service life.

The utility model is because buffer gear has dumping force, case lid is covered in the whereabouts produce the effect of braking slowly in the process, avoid case lid quick and casing upper edge generation bump and generation vibrations and sound under gravity and force of inertia effect, and simple in structure, with low cost.

Description of drawings

Fig. 1 is a rubbish container open mode lateral plan, and its midship section place is the scheme drawing of the utility model buffer gear 1 embodiment;

Fig. 2 covers side view of the state for Fig. 1 embodiment rubbish container.

Fig. 3 is Fig. 1 left view.

The specific embodiment

With reference to Fig. 1, Fig. 2, the casing 3 of plastic garbage case is connected by hinge 2 with case lid 1, embodiment as buffer gear, the elastic damping wedge of being made by silaatic or latex or elastic polyester material 9 is being arranged near the cooresponding stationkeeping of case lid inner top surface and position, casing side upper edge of hinge, with the elastic damping wedge be that cancave cambered surface 31 is made in the upper surface, position, the cooresponding casing side upper edge of camber line that the center of circle rotate to form with the hinge, the thick end wedge tail of elastic damping wedge is fixed on the case lid inner top surface, thin end wedge point is close in case lid lower cover process and is slided and bending gradually along described cancave cambered surface, the thickness of elastic damping wedge wedge tail should guarantee still not to be bent when case lid arrival covers the position during design, and the thickness at all the other positions should guarantee the gravity of its elastic force less than case lid.

In the various embodiments described above, be installed with cushion 11 at inner top surface away from two jiaos of the case lids on hinge limit.
