Abstract

The utility model discloses a dead locking mechanism for a garbage door. The dead locking mechanism for the garbage door is used for a garbage can, and comprises the garbage door. The upper side of a garbage inlet is connected with the upper side of the garbage door through a hinge. A screw shaft is connected to the position, close to the garbage door, of the inner wall of a frame of the garbage can. The screw shaft is movably connected with the middle of a locking piece. The locking piece can rotate around the screw shaft. One end of the locking piece is heavier than the other end of the locking piece. The heavier end of the locking piece is located on the inner side of the screw shaft to be pressed on an edge opening of an inner cylinder. The lighter end of the locking piece is located on the outer side of the screw shaft. A protruding limiting platform is arranged at the rear portion of the locking piece. An upper limiting point and a lower limiting point are arranged on the limiting platform. When the inner cylinder for collecting garbage inside the garbage can is lost or is damaged or is not installed in place, the garbage door at the garbage inlet can be dead locked, and a person is not allowed to put garbage into the garbage can until a new inner cylinder is placed into the garbage can again. The garbage can is prevented from being further damaged, the working intensity of a sanitation worker for cleaning garbage is reduced, the structure is simple and reliable, the manufacturing cost is low, and use is convenient.

Description

Chute door locking mechanism

Technical field

The utility model relates to a kind of public environment sanitation facility rubbish container, relates in particular to a kind of chute door of rubbish container.

Background technology

The garbage inlet place of existing rubbish container is all provided with chute door, for preventing rubbish stink in rubbish container to external diffusion or preventing fly turnover rubbish container.For example: the chute door device of 200620097137.4 rotary refuse gates, 94219104.8 magnetic semi-automatic refuse doors, 99253701.0 anti-blocking chokes.Their common ground is all equipped with manually or the chute door that utilizes rubbish to open in garbage inlet, but jointly deposits a problem, and in the time that nothing in rubbish container is collected the interior bucket of rubbish, chute door still can be opened.Interior bucket in actual life in rubbish container is often lost or is damaged, and rubbish container just cannot be realized garbage collecting function.If at this moment still rubbish is dropped into, by rubbish or sewage are flowed out from the gap of rubbish container, can accelerate the corrosion damage of rubbish container inside simultaneously, also bring tired heavy cleaning work to sanitationman.

Summary of the invention

For overcoming existing chute door in the still openable defect of interior when bucket without collecting rubbish, the utility model provides a kind of chute door locking mechanism, and this chute door locking mechanism chute door in the time of the interior bucket without collecting rubbish is not opened.

The technical solution of the utility model is: this chute door locking mechanism comprises chute door, garbage inlet upside is connected with chute door upside by hinge, be connected with spiral shell axle at rubbish container frame inner wall near near chute door, spiral shell axle is connected with the intermediate active of locking plate, locking plate can rotate around spiral shell axle, locking plate one end is than other end weight, locking plate is heavily held and is positioned at spiral shell axle inner side and is pressed on inner core bead, the light end of locking plate is positioned at spiral shell axle outside, locking plate rear portion is provided with protruding limit dais, and limit dais is provided with upper limit site and lower limit site.

Interior bucket by the slightly heavy one end of locking plate jack-up, makes the light end of locking plate depart from the path that chute door is opened in the time of normal position, and chute door can normally open or close.When in rubbish container without interior when bucket, locking plate is heavily held under Action of Gravity Field and is pivoted, and the light end of locking plate is forwarded on the path that chute door opens, and while at this moment pushing away chute door again, will gently be held dieback by locking plate, rubbish container is no longer accepted rubbish and is dropped into.

The upper limit site of the limit dais of locking plate rear portion projection and lower limit site can prevent that locking plate from departing from predetermined angle while rotation.

The utility model advantage is: when the interior bucket of rubbish container internal gathering rubbish lose, damaged or install time not in place, can, by locked the chute door of garbage inlet, not allow people drop into again rubbish, until be reentered into interior bucket.Avoid allowing rubbish container suffer further infringement, reduce sanitationman and clear up the working strength of rubbish, allow the people of garbage throwing is conscious removes to find next normally functioning rubbish container.Simple and reliable for structure, low cost of manufacture, easy to usely saves worry.

Accompanying drawing explanation

Fig. 1 is the structural representation of an embodiment of the present utility model.

Fig. 2 is the schematic top plan view of Fig. 1.

Fig. 3 is the schematic diagram under the chute door locking state of Fig. 1.

In figure: 1. rubbish container housing, 2. frame inner wall, 3. hinge, 4. garbage inlet, 5. chute door, 6. interior barrel of bead, 7. locking plate is heavily held, 8. locking plate, 9. limit dais, 10. upper limit site, 11. lower limit sites, 12. nuts, 13. spiral shell axles, 14. locking plates are gently held, 15. interior buckets.

The specific embodiment

In Fig. 1, Fig. 2, in garbage inlet 4, use hinge 3 that chute door 5 is installed, be welded with a spiral shell axle 13 at the frame inner wall 2 of rubbish container housing 1 near the position of chute door 5, on spiral shell axle 13, cover has locking plate 8, and fixing with nut 12.Spiral shell axle 13 is connected with the intermediate active of locking plate 8, and locking plate 8 can rotate around spiral shell axle 13.Locking plate 8 left ends are that locking plate heavily holds 7, and locking plate 8 right-hand members are the light end 14 of locking plate, and locking plate heavily holds 7 than light end 14 Heavy Weights of locking plate.Locking plate heavily holds 7 to be positioned at spiral shell axle 13 inner sides and to be pressed on inner core 15 beads, and locking plate gently holds 14 to be positioned at spiral shell axle 13 outsides.Interior bucket 15 is placed on bottom in rubbish container, and locking plate heavily holds 7 to be pressed on interior bucket bead 6, and according to the angle setting, locking plate gently holds 14 below chute door 5, to depart from the path that chute door 5 is opened, and now chute door 5 can normally be opened (as shown in arrow A direction in Fig. 1).

In Fig. 3, in the time that the interior bucket 15 in rubbish container is extracted out or loses, locking plate heavily holds 7 to rotate below because gravity reason drives locking plate 8 left, make the light end 14 of locking plate forward chute door 5 left ends to, and gear opening on path at chute door 5, at this moment chute door 5, by locked and cannot push open, has also just reached object of the present invention.

Simultaneously, because locking plate 8 rear portions are provided with protruding limit dais 9, limit dais 9 includes upper limit site 10 and lower limit site 11, bucket 15 o'clock in inserting or extracting out, the rotational angle of locking plate 8 is all limited in pre-designed angular range by upper change point 10 and lower limit site 11, prevents that locking plate 8 inordinate rotation from losing function.
