Description
Technical field
The present invention relates to the field of medical instrument technology, a kind of particularly sterilizer.
Background technology
Sterilizer carries out disinfection medical instrument by the saturated vapor for the high temperature and pressure importeding into chamber, will sterilize
Medical instrument arrangement in the cavity.
Sterilizer needs to seal and bears certain pressure, and door latch structure is for by hermatic door and body lock in sterilizer
Tight mechanism, is to ensure sterilizer under the steam pressure of compression 0.26MPa, hermatic door will not be opened, and hermatic door and main body
Between do not have steam leakage.
Existing sterilizer door lock construction is sealed using the mode of withholding more, in pressurization, hermatic door cunning easily occurs
It is de-, lock not firm situation, due to hinge mounting door latch hook, it is impossible to the cooperation distance of hermatic door and cylinder is adjusted, when adopting
When being driven with drive ring, the distance of drive ring range gate latch hook is slightly remote, will result in force structure and disperses, easily in motion process
In cause door lock hook catching phenomenon.
The content of the invention
The object of the present invention is to provide a kind of sterilizer rational in infrastructure, sealing effect is good.
The technical scheme is that：A kind of sterilizer, including cylinder and cover, are equipped with hinge and fill between cylinder and cover
Put and locking device, it is characterised in that：The locking device includes no less than 3 groups of closing piece units and for driving closing piece unit
Drive ring, the closing piece unit include mounting platform, fixing axle, shaft and ear closing piece, and the mounting platform is welded on cylinder
On lateral wall, the upper plane of mounting platform parallel to cartridge openings place plane described in drive ring pass through shaft and locked with ear
Block is connected, the fixing axle and ear closing piece by being threadably mounted on mounting platform,
The first arc-shaped edges of outer cause of the ear closing piece, the second arc-shaped edges, first straight line are in, three-arc, the 4th
Arc-shaped edges and second straight line side join end to end composition successively, first arc-shaped edges, the second arc-shaped edges, three-arc side and the 4th
The corresponding central angle of arc-shaped edges is 90 °, and the strip hole parallel to first straight line side, the strip hole two are equipped with the middle part of ear closing piece
Hold as semicircle, half diameter of a circle is equal with the width of strip hole, and the ear closing piece is equipped with close to three-arc side one end
Circular hole,
The shaft is engaged with the circular hole on ear closing piece, and the diameter of the fixing axle and the width of strip hole match
Close, the outer rim of the drive ring installs driven rack, and the locking device further includes drive gear, drive gear and driven rack
It is engaged, the cover is equipped with and the matched closing piece jack of ear closing piece.The present invention is using eccentric ear closing piece, servo
Motor drives drive gear, controls drive ring to move back and forth by driven rack, when drive ring moves, drive ring passes through shaft band
Dynamic ear closing piece rotates, and ear closing piece coordinates the limitation of strip hole for eccentric design, makes the diagonal rotation that ear closing piece is longer
Where to cartridge openings on the radial direction of circle, relative to the fixed form of strip dead bolt of the prior art, closing piece is in cylinder
Occupy-place is small on the radial direction of circle where body opening, has been effectively saved space, has reduced the outer dia size of cylinder, and
And drive ring is directly coupled by bolt with door lock block, shortens driving torque, it is ensured that the totally tansitive of power, can guarantee that
The smooth rotation and closing piece of drive ring flexibly stretch.
The fixing axle outer surface is equipped with external screw thread, and mounting platform is equipped with and the matched interior spiral shell of external screw thread in fixing axle
Line, fixing axle lower end are equipped with and the matched nut of fixing axle.The screw thread of mounting platform, fixing axle and nut, which is set, locks ear
Block can be adjusted in the short transverse of sterilization cylinder, so that closing piece coordinates with cover upper locking piece jack.
Locating piece is additionally provided with the fixing axle, the locating piece is installed between mounting platform and ear closing piece, described
Locating piece is equipped with and the matched internal thread of fixing axle external screw thread.Ear is formd between cap portion at the top of locating piece and fixing axle
The activity spacing of shape closing piece, cap portion are fixed, and the position of locating piece in vertical direction have adjusted locating piece and fixing axle
Thickness between the cap portion at top, so as to influence the fluency of ear closing piece rotation.
First arc-shaped edges, the second arc-shaped edges, the ratio between the radius of three-arc side and the corresponding circle of the 4th arc-shaped edges are
5:7:4:6, which determines the length on the radial direction that ear closing piece is justified where cartridge openings, has reasonably taken into account close
The size of envelope effect and ear closing piece, the undersized reliability for reducing sealing of ear closing piece, oversized and occupancy are larger
Space..
The present invention has the advantages and positive effects of：Due to the adoption of the above technical scheme, sterilizer retaining mechanism takes
Space is few, easy to operate, locking is safe and reliable.
