Description
Technical field
The invention belongs to medical sterilizer fields, and in particular to a kind of release mechanism of nacelle door.
Background technology
Currently, the nacelle door of sterilizer usually drives lifting by built-in cylinder, but when the nacelle door closing of sterilizer,
Even if can by force be closed under cylinder action if thering are operating personnel's limbs or sterilizing article to appear in close side nacelle door, due to
Lack anti-pinch, the protection of anti-obstacle, so can hurt operating personnel or destroy sterilizer structure, there is larger safety is hidden
Suffer from.
To solve the above-mentioned problems, occur realizing anti-pinch, anti-barrier using contact microswitch or photoelectric sensor
The technology hindered.But still have following disadvantage：The region of protection is limited, and validity is poor；It is easy by environment near sterilizer
Temperature and humidity influences, and malfunction or entirely ineffective；Electronic original part in high temperature high-heat environment short life, often to safeguard,
It replaces；It can fail when system burst failure dependent on sterilizer control system.
Invention content
The technical problem to be solved by the invention is to provide a kind of safe machines that can be realized sterilizer nacelle door and normally lift
Structure not will produce the big contact force for leading to human injury to realize nacelle door during the motion, will not encounter obstacle
When destroy sterilizer structure.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of release mechanism of nacelle door, including set
Set the guard plate above nacelle door, the cylinder body of the cylinder in nacelle door and unidirectional at the top of the cylinder body
Valve, the guard plate is located above the check valve, is arranged between the nacelle door and the guard plate and has elastic component, described
Limiting plate is installed on guard plate, hook is installed on the nacelle door, the hook coordinates with the limiting plate to limit peace
The range of full plate.
In addition, the present invention also proposes following attached technical scheme.
Preferably, the elastic element is spring.
Preferably, the elastic element is spring leaf.
Preferably, there are two elastic elements for setting between the nacelle door and the guard plate.
Preferably, the limiting plate is fixedly mounted on by positioning pin on the guard plate.
Preferably, two pieces of limiting plates are provided on the guard plate.
Preferably, it is provided with inlet channel in the piston rod of the cylinder.
Preferably, the lower end of the piston rod of the cylinder is provided with air inlet.
Preferably, the cylinder body of the cylinder is bolted to connection on the nacelle door.
Preferably, when closed, if hindered above the guard plate, the elastic element can quilt for the nacelle door
Compression, the guard plate are moved downward relative to the nacelle door, touch the check valve, check valve just opens pressure release
Compared with the prior art, the advantage of the invention is that：The nacelle door of sterilizer is power by a compressed air
Cylinder realize lifting, the protection of sports safety, and the limiting plate by being arranged on guard plate are realized using check valve
Coordinate with the hook that is arranged on nacelle door, limit the range of guard plate, so as to prevent from crushing or obstacle damage.
The release mechanism of the nacelle door of the present invention is pure mechanic structure, is simply, reliably and independent of sterilizer control
The working condition of system, so more safely, effectively.

Specific implementation mode
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its attached drawing.
As shown in Figure 1 and Figure 2, the release mechanism of nacelle door of the present invention includes the cylinder body 1 for the cylinder being mounted in nacelle door 6,
It is fixed on the piston rod 2 of supporting surface, the cylinder body 1 of cylinder is set on piston rod 2.The top of cylinder body 1 passes through bolt 7 and nacelle door
6 rigid connections.Inlet channel 22 is provided in piston rod 2, the lower end of piston rod 2 is provided with the air inlet 21 of compressed air.
Hook 9 is installed on nacelle door 6.Preferably, hook 9 there are two being left and right symmetrically arranged on nacelle door 6.
The top of nacelle door 6 is provided with guard plate 5, and guard plate 5 is supported by the elastic element 4 for being fixed on nacelle door 6.Such as figure
Shown in 1, elastic element 4 is spring.As shown in Fig. 2, elastic element 4 or spring leaf.Preferably, fixed on nacelle door 6
There are two elastic elements 4.Certainly, elastic element 4 may be set to be one or more.
Limiting plate 10 is installed on guard plate 5.Preferably, two pieces of limiting plates 10 have been left and right symmetrically arranged on guard plate 5, and
It is correspondingly arranged respectively with two hooks 9 on nacelle door 6.After guard plate 5 installs, respectively it is pressed on two pieces of limiting plates 10
Positioning pin 8 makes it will not fall off for limiting moving left and right for guard plate 5.
At the top of cylinder body 1, setting is under normal circumstances, single there are one the mechanical check valve 3 that air pressure can be utilized to automatically reset
To valve 3 not by outer force effect, it is always maintained at closed state.
The operation principle of the release mechanism of the nacelle door of the present invention is as follows.
As shown in Figure 1 and Figure 2, when the air inlet 21 of piston rod 2 accesses the compressed air of stable (fixation pressure and flow velocity)
Afterwards, the pressure that compressed air along the inlet channel 22 of piston rod 2, can reach the cylinder body 1 of the cylinder at top and piston rod 2 is formed
Chamber 11, compressed air can push cylinder body 1 to be moved up along piston rod 2.The speed for controlling compressed air air inlet, can control
The speed that cylinder body 1 processed moves.Since the top of cylinder body 1 is rigidly connected by bolt 7 and nacelle door 6, utilization is just realized in this way
Compressed air has lifted nacelle door 6.
When closed, if 5 top of guard plate is hindered, elastic element 4 will be compressed nacelle door 6,5 phase of guard plate
Nacelle door 6 is moved downward, check valve 3 is touched, check valve 3 just opens pressure release.The obstruction power that guard plate 5 is subject to is bigger,
The opening degree of check valve 3 will be bigger, until the thrust of compressed air and the gravity of nacelle door 6 add the resistance on guard plate 5
The sum of power is hindered to reach new balance so that 6 stop motion of nacelle door.
As long as the reasonably coefficient of elasticity of selection elastic element 4, just can control guard plate 5 and (be unlikely to by particular size
Cause to crush, damage) obstruction force effect when displacement relative to nacelle door 6, to check valve 3 opening degree namely let out
Pressure value is controllable namely the thrust magnitude of compressed air is controllable.In this way, the closing process of nacelle door 6 is just very safe.
Above-mentioned release mechanism not only reliable in action, and have simple in structure, component costs are low, and mount and dismount facility
The characteristics of, it only can be all installed in place from the surface of nacelle door 6, and do not need extra machinery adjustment.
The nacelle door of the sterilizer of the present invention realizes lifting by the cylinder that a compressed air is power, utilizes a list
The protection of sports safety, and the limiting plate 10 by being arranged on guard plate 5 and the extension that is arranged on nacelle door 6 are realized to valve 3
Hook 9 coordinate, limit guard plate 5 range, so as to prevent from crushing or obstacle damage.The safety of the nacelle door of the present invention
Mechanism is pure mechanic structure, simple, reliable and independent of the working condition of sterilizer control system, thus more safely, have
Effect.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements according to this, and the protection of the present invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
