Description

Foldable trash

Technical field

It is especially a kind of to match the folded garbage used with hospital dressing change cart the utility model relates to dustbin field Bucket.

Background technique

Medical staff can generate many rubbish during to changing medicine for patient.At present medical staff frequently with rubbish receive Packaging is set to the small-sized rubbish collection box for being placed in dressing change cart lower layer, but using when must bend over to be opened rubbish box cover with hand, open Inconvenient and unhygienic (may have blood, body fluid etc. when dressing on gloves, opening lid can pollute), and capacity is small.

105109861 A of Chinese patent prospectus CN discloses a kind of folding garbage bin, this dustbin is by two Bottom bar is hinged together, and support rod is fixed at every low bar both ends respectively, and collapsible, is allowed to not take up space when not used. But do not meet hospital's hygienic requirements without bung, and place it in it is not very convenient on dressing change cart.

Utility model content

The technical issues of the utility model solves is to provide a kind of cooperation hospital's dressing change cart use more easily dustbin, no Only it is not necessarily to manually opened dustbin cover, and capacity is big, space is saved in foldable placement when not in use.

To solve the above problems, the foldable trash of the utility model includes mounting base, is fixed on the mounting base one The holding stand for garbage sack of side and the dustbin cover above holding stand for garbage sack are between the dustbin cover and the mounting base It is flexibly connected；The holding stand for garbage sack includes upper frame and lower frame, and the upper frame and lower frame include that head and the tail are hinged on Four connecting rods together are equipped with four scalable columns between the upper frame and the lower frame；The dustbin cover includes Plate one and plate two, by hinge connection among the plate one and plate two；Between the mounting base and the dustbin cover Equipped with dustbin cover opening device.

The dustbin cover opening device includes oscillating rod, and the first end of the oscillating rod is fixedly mounted on the dustbin Lid side is hinged in the mounting base in the middle part of the oscillating rod, and the second end of the oscillating rod is hinged with vertical link, institute The lower end for stating vertical link is equipped with horizontal axis；The arc-shaped slot being oppositely arranged is offered in the mounting base, horizontal axis both ends difference It stretches out and can be moved along this arc-shaped slot from corresponding arc-shaped slot；Turning set, the rotation are rotatably equipped on the horizontal axis It puts on and is fixedly installed with swing arm, the lower end of the swing arm is fixedly installed with foot pedal.It is equipped with inside the swing arm towards institute The pilot hole that horizontal axis extends and penetrates the turning set is stated, the pilot hole is movably installed with locking pin, and the locking pin is separate There is a shifting block in one end of horizontal axis；The lower part of the horizontal axis is equipped with the groove to match with this locking pin；The locking pin bottom A spring is equipped between the bottom of the pilot hole；The swing arm and the shifting block corresponding position are provided with one and the guiding The strip slot of hole perforation；Shifting block on the locking pin is stretched out from this strip slot, and can be moved along this strip slot.It is described It is fixedly installed with locating piece in mounting base, is equipped between the locating piece and the swing arm so that the swing arm turns counterclockwise Dynamic tension spring.

The scalable column includes outer tube and covers the elastic activity bar in the outer tube, and the elasticity activity bar is in U-shape, and is in One arm of the elastic activity bar of U-shaped is fixedly installed with fixture block, and the inner wall of the outer tube is equipped with the card cooperated with the fixture block Slot, another arm for the elastic activity bar being in U-shape are fixedly installed with the guide post above fixture block, the guide post activity It is mounted in the outer tube.

The mounting base side opposite with holding stand for garbage sack has to match hook with dressing change cart.

With such a structure, since upper frame and lower frame include four hinged connecting rods of head and the tail, Four scalable columns are equipped between upper frame and lower frame, convenient for diagonally adjusting frame and lower frame according to size of garbage bags And it pinches elastic activity bar and adjusts distance between upper frame and lower frame.Since dustbin cover includes plate one and plate two, in Between by hinge connection, when not in use can by plate two-fold, save space.Due to being equipped with rubbish between mounting base and dustbin cover Bung opening device is bonded when use with foot pedal spacing block set to block with foot rotation swing arm, makes locking pin along pilot hole It is caught in horizontal axis groove, dustbin cover can be opened by then stepping on foot pedal.Since the presence of hook hangs over dustbin On dressing change cart, use is very convenient.
