Description
Technical field
The invention belongs to medical sterilizer field, and in particular to a kind of release mechanism of nacelle door.
Background technology
At present, the nacelle of sterilizer generally drives lifting by built-in cylinder, but during the nacelle door closing of sterilizer,
Even if having operating personnel's limbs or sterilizing article to appear in close side, nacelle door also can by force be closed under cylinder action, due to
Lack anti-pinch, the protection of anti-obstacle, so operating personnel or destruction sterilizer structure can be hurt, there is larger safety hidden
Suffer from.
In order to solve the above problems, occur in that using contact microswitch or photoelectric sensor to realize anti-pinch, anti-barrier
The technology for hindering.But following shortcoming is still present：The region of protection is limited, and validity is poor；Easily by environment near sterilizer
Temperature and humidity influences, and misoperation or entirely ineffective；Electronic original part in high temperature high-heat environment short life, often to safeguard,
Change；Sterilizer control system is depended on, when system burst failure, can be failed.
The content of the invention

Specific embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As shown in Figure 1 and Figure 2, the release mechanism of nacelle door of the present invention includes the cylinder body 1 of the cylinder in nacelle door 6,
The piston rod 2 of supporting surface is fixed on, the cylinder body 1 of cylinder is set on piston rod 2.The top of cylinder body 1 is by bolt 7 and nacelle door
6 are rigidly connected.Inlet channel 22 is provided with 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, two hooks 9 have been 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 flexible member 4 for being fixed on nacelle door 6.As schemed
Shown in 1, flexible member 4 is spring.As shown in Fig. 2 flexible member 4 can also be spring leaf.Preferably, it is fixed on nacelle door 6
There are two flexible members 4.Certainly, flexible member 4 it can also be provided that 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 is installed, each it is pressed on two pieces of limiting plates 10
Alignment pin 8, for limiting moving left and right for guard plate 5, will not fall off it.
An energy is provided with using the automatically reset mechanical check valve 3 of air pressure at the top of cylinder body 1, it is under normal circumstances, single
Do not acted on by external force to valve 3, be always maintained at closed state.
The operation principle of the release mechanism of nacelle door of the 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 stabilization (fixation pressure and flow velocity)
Afterwards, compressed air can be along the inlet channel 22 of piston rod 2, the pressure of cylinder body 1 and piston rod 2 formation of the cylinder at the top of arrival
Chamber 11, compressed air just can promote cylinder body 1 to be moved up along piston rod 2.The speed of compressed air air inlet is controlled, just can be controlled
The speed of the movement of cylinder body processed 1.Because the top of cylinder body 1 is rigidly connected by bolt 7 and nacelle door 6, utilization is so just realized
Compressed air has lifted nacelle door 6.
When closed, if the top of guard plate 5 is hindered, flexible member 4 will be compressed nacelle door 6, the phase of guard plate 5
Moved downward for nacelle door 6, touch check valve 3, 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, and the resistance on guard plate 5 is added until the gravity of thrust and the nacelle door 6 of compressed air
Power sum is hindered to reach new balance so that nacelle 6 stop motions of door.
As long as reasonably the coefficient of elasticity of selection flexible member 4, just can control guard plate 5 (to be unlikely to by particular size
Cause and crush, damage) hinder the masterpiece used time relative to the displacement of nacelle door 6, so as to the opening degree of check valve 3 namely let out
Pressure value is controllable, namely the thrust magnitude of compressed air is controllable.So, the closing process of nacelle door 6 is just very safe.
Above-mentioned release mechanism not only reliable in action, and have simple structure, component costs are low, and installation and removal facility
The characteristics of, only the surface from nacelle door 6 can all be installed in place, and not need unnecessary machinery adjustment.
The nacelle door of sterilizer of the invention is the cylinder realization lifting of power by a compressed air, using a list
The protection of sports safety is realized to valve 3, and by the limiting plate 10 being arranged on guard plate 5 and the extension being arranged on nacelle door 6
Hook 9 coordinates, and limits the range of guard plate 5, such that it is able to prevent from crushing or obstacle infringement.The safety of nacelle door of the invention
Mechanism is pure mechanic structure, simple, reliability and does not rely on the working condition of sterilizer control system, thus more safely, have
Effect.
It is pointed out that above-mentioned preferred embodiment is only explanation technology design of the invention and feature, its object is to
Allow person skilled in the art will appreciate that present disclosure and implement according to this, protection of the invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, should all be included within the scope of the present invention.
