Abstract

The utility model relates to a garbage container, specially a pedal open cover type dustbin, which comprises a pedal mechanism, a bin body (4) and a cover plate (1). A pedal plate (6.2) in the pedal mechanism is on external end of a lever (6.1), upper end of a top rod (11) is hinged with bottom surface of the cover plate (10, lower end of the top rod (11) is parallel with a fixing connection rod (5), a piston (10) that is installed on one bottom of the top rod (11) or the connection rod (5) has sliding fit with inner wall of inflator (9) of a inflator device, a piston that is installed on two bottoms of the top rod (11) or the connection rod (5) is hinged at inner end of the lever (11). For the utility model, since an air flow channel is formed at the gap between conic surface in upper port of valve seat and top of valve core, the gap is adjusted to smaller by rotating the valve core, when the bin cover drops due to its own weight, air in the cavity of the inflator can be released slowly so that the bin cover can drop slowly and gently so as to avoid sound caused by impact of the bin opening and other harms caused by impact.

Description

A kind of foot-operated open type rubbish container

Technical field

The utility model relates to refuse container, particularly a kind of foot-operated open type rubbish container.

Background technology

Foot-operated rubbish container of the prior art is made up of footstep mechanism, casing and case lid usually, and the pedal in the footstep mechanism is loaded on the outer end of lever, and the lower end of push rod is articulated in the inner of lever, and the upper end of push rod is articulated in the case lid bottom surface.This simple and practical, but an one obvious defects is, when pin one left pedal, case lid was fallen after rise fast with the case mouth by its deadweight and fastens, case lid bump case mouth, and the one, send the loud noise noise of ", ", near resident's the sleep influence at night; The 2nd, make casing produce bigger vibrations, the paint on its surface is peeled off easily, and the iron sheet casing is easily by corrosion; The 3rd, if not withdrawal rapidly of hand, finger is crushed easily.

The utility model content

The purpose of this utility model is to overcome weak point of the prior art, and provides a kind of case lid can flexiblely close the foot-operated open type rubbish container that closes.

The purpose of this utility model realizes by following approach; A kind of foot-operated open type rubbish container, comprise footstep mechanism, casing and cover plate, pedal in the footstep mechanism is loaded on the outer end of lever, the upper end of push rod is articulated in the case lid bottom surface, the lower end affixed connecting rod also in parallel that it is characterized in that push rod, be loaded on the piston of one of lever or connecting rod bottom and the cylinder inner wall bearing fit of inflator device, two bottoms that are loaded on lever or connecting rod are articulated in the inner of lever.

Valve seat is equipped with in the inflator bottom, and spool makes the relative valve seat advance and retreat of spool with the valve seat screw thread fit.

Spool has the open inner chamber in bottom, opens in the pore on spool top the inflator inner chamber is communicated with valve core cavity the spool position hoop cover seal ring of pore top.

Valve seat is connected with the inflator bottom thread at the bottom of running through case, makes circular conical surface in the valve seat upper port, and the gap between itself and the spool top constitutes gas channel.

The utility model is because circular conical surface in the valve seat upper port and the gap between the spool top constitute gas channel, by the turn spool, arrive this gap adjustment less, when pin leaves pedal, case lid is fallen after rise by its deadweight, but because gas channel is less, the air of inflator inner chamber can only slowly be released, so case lid can only be slowly, mildly fall after rise, and gas channel adjustable gaps, the speed of the falling of case lid is also adjustable, has avoided sound that case lid produced case mouth bump and peeled off, point easily by the paint that bump produces other harm such as being crushed easily.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the local enlarged diagram at Fig. 1 K place.

Mark among the figure: 1 cover plate, 2 free bearings, 3 hinges, 4 casings, 5 connecting rods, 6.1 levers, 6.2 pedals, 6.3 balance pivots, 7 spools, 7.1 pores, 7.2 valve core cavities, 8 valve seats, 9 inflators, 10 pistons, 11 push rods, 12 hinges, 13 gaps, 14 seal rings.

The specific embodiment

With reference to Fig. 1, Fig. 2, foot-operated open type rubbish container, footstep mechanism are loaded on outside at the bottom of the case, and casing 4 is connected by hinge 12 with cover plate 1, and pedal 6.2 is the outer end of lever 6.1; The upper end of push rod 11 is connected in the free bearing 2 of case lid 1 bottom surface by hinge 3, and welding bifurcated connecting rod 5 in parallel is adopted in the lower end, and piston 10 is equipped with in push rod 11 bottoms, and piston 10 cooperates with the inflator 9 inwall slipper seals of inflator device.The lower end of connecting rod 5 is connected in the inner of lever 6.1 by hinge 6.4, and 6.3 at the fulcrum of lever 6.1 is in ground or at the bottom of being fixed in case; The coupling link of connecting rod 5 and push rod 11 bottoms is interchangeable.

Valve seat 8 runs through at the bottom of the case to be connected with the bottom thread of inflator 9 inflator 9 is fixed in casing 4 bottoms, spool 7 and valve seat 8 screws thread fit, spool 7 has the open inner chamber 7.2 in bottom, open 1-2 pore 7.1 in spool top, the inner chamber of inflator 9 is communicated with the inner chamber 7.2 of spool 7, and the spool position hoop of pore 7.1 tops is with seal ring 14; Make circular conical surface in valve seat 8 upper port, the gap 13 between circular conical surface and spool 7 tops or the seal ring 14 constitutes gas channel.

Turn spool 7 can make spool 7 relative valve seat 8 advance and retreat, and the width in scalable gas channel gap 13 also is the scalable airshed, and then the speed of the falling of scalable case lid 1.
