At this point, the rope on pulley 12a is stretched, as shown in Fig. 2, fixed pulley 12b with the direction of action of rope 13 and
Rotation, handle 23 is lifted up by rope 13, and rope 13 is the output end of turbine and worm 2, by pulley blocks (pulley 12a and fixed
Pulley 12b) it is connected with handle 23.
Spring contact 15 is no longer influenced by the active force that doorframe applies it, rope during main door 8 is opened by being closed to
Rope 13 promotes handle 23 through fixed pulley 12b and moves upwards.Spring contact 15 is with the contact point of lever 14 by connecing in following procedure
It touches to non-contact excessive.Specifically, flashboard 11 has one end of section to flank with lock tongue 16 during handle 23 moves upwards
Touching applies thrust and upward active force to the left to lock tongue 16, and 16 compressed spring 24 of lock tongue applies active force to the left to it, from
And 25 left movement of connecting rod, being based on fulcrum 26 with the lever 14 that connecting rod 25 links rotates clockwise, and lock tongue 16 is by connecting rod 25 at this time
Pulling force to the left moves downward, so that flashboard 11 rises, spring 24 is compressed to the left at this time.After flashboard 11 passes through, lock tongue 14 exists
It is resetted under the promotion of spring 24, flashboard 11 is blocked and is led.Specifically, being locked when flashboard 11 is risen to completely on 14 upper surface of lock tongue
Tongue 14 resets to play position-limiting action to flashboard 11, prevents flashboard 11 from declining, at this time the quilt between support 7 and flashboard 11 of spring 27
Compression.Lock tongue 16 and 24 junction of spring are mounted in lock housing 28, and when lock tongue 14 resets, spring 24, which withstands lock tongue 14, to be made at its
In the state of stretching, prevent flashboard 11 from declining.Further, lock housing 28 has position-limiting action to lock tongue 24, make its can only stretching motion,
To prevent the gravity of the components such as handle 23, cervical orifice of uterus 1 from lock tongue 24 being caused to rotate.
Wherein, handle 23 is mounted on the lower part of main door 8 by support 7, flashboard 11 and support 7 jointly limitation handle can only on
Lower movement.
Further, while turning door handle 21, the rope 18 on fixed pulley 17 is stretched, and then pulls connecting rod
22 are moved to the left, and by compression, lock tongue 20 is shunk spring 29 to the left simultaneously, release and limit to flashboard 10, spring 30 is by compressing at this time
To stretching, extension push flashboard 10 rise, thus through handle 31 drive support 7 rise, in conjunction with above structure drive cervical orifice of uterus 1 quickly on
It rises.After main door 8 fully opens, cervical orifice of uterus 1 is unfolded, and an area of isolation is formed between toilet and surge chamber.
Fig. 3 is the status diagram that main door 8 of the present invention fully opens, as shown in Figure 3.Flashboard 10 is promoted on lock tongue 20
Afterwards, main door 8 continues to open, and the continuation of rope 13 is pulled by turbine and worm 2 in support 7 at this time, 7 entire lowering of support.To lock
Plate 10 also declines therewith, until flashboard 10 overcomes the friction between lock tongue 20 to be placed in below, with door handle 21

Carry out accumulation of energy preparation.
Fig. 4 is structural schematic diagram of the technical solution of the present invention when main door 8 is closed, as shown in Figure 4.
When main door 8 is closed, when main door 8 and doorframe are closely sealed, doorframe applies pressure to spring contact 15.Spring contact 15 is to it
Apply active force to the right with the contact point of lever 14 so that lever 14 is based on fulcrum 26 and rotates clockwise, drive connecting rod 25 to
Left movement is further driven to lock tongue 16 and moves downward.At this point, lock tongue 16 is withdrawn from below flashboard 11, lock tongue 16 is to flashboard 11
Position-limiting action releases, and cervical orifice of uterus 1 declines.Specifically, when lock tongue 16 releases the limit to cervical orifice of uterus 1, the stretching, extension release elastic force of spring 27,
Thrust is generated to flashboard 10, further speeds up and pushes down cervical orifice of uterus 1, until it touches ground, cervical orifice of uterus 1 further completely cuts off toilet
Inner air and outer air flowing, plays sealing effect.In the process, handle simultaneously declines, and turbine and worm 2 is opened compared to main door 8
When counter motion, support 7 declines, to rotate immediately in door handle 21 at closing time, flashboard 10 will not rise.
Wherein, lever 14 is using resistance arm (resistance arm lengths are less than power arm) design, to amplify the output of lever 14
Distance.One end of connecting rod 25 is connect with lever 14, and the other end is connect with lock tongue 16, and the section end of lock tongue 16 is associated with fortune with flashboard 11
It is dynamic.Specifically, for lock tongue, the design of lock tongue both ends is different, close to one end of connecting rod use with compressed spring elastic connection and
The dual connection type that it is fixedly connected with connecting rod uses the design method of section design close to one end of flashboard, for working as
It can make flashboard pass through to son by thrust to the left to compressed spring when moving upwards with flashboard to reduce resistance
Door 1 is unfolded.Further, shape of the section of lock tongue with flashboard close to lock tongue side matches.
Wherein, lock tongue both ends separately design as shown in figs 2-4, and one end is fixedly connected with connecting rod and spring；The other end is
The gradient of section, section side is matched with flashboard, the other side, when the section of lock tongue is in flashboard relative motion, reduces flashboard resistance
Power, conversely, increasing ram movement resistance and limiting.
Pulley blocks can move up and down in support 7.Specifically, cause pulley 12a to rotate referred to herein as the rotation of drive shaft 9,
Power is transferred at handle 23 by rope 13.With the tension of rope, pulley 12b becomes smaller at a distance from support 7.Similarly, with
The relaxation of rope 13, pulley 12b become larger at a distance from support 7.Variation between both they position is to move up and down to close
System.
Now cervical orifice of uterus 1 is further illustrated, as shown in figure 5 a and 5b, cervical orifice of uterus 1 has two flexible side plates, their junctions are set
There is a Flexible Rotating 32,1 bottom end doorframe of cervical orifice of uterus is elastic soft bottom frame.
Side view of the cervical orifice of uterus 1 during expansion and decline is dove-tail form.It combines design using flexible back bone and software.
The elastic soft bottom frame of 1 bottom end of cervical orifice of uterus can deform, specifically, in 1 motion process of cervical orifice of uterus, two flexible side plate unbalance stress
It is even, become A (surge chamber side), B (in cervical orifice of uterus 1), three regions C (toilet side), so that between toilet and surge chamber
A cushion space is further increased, isolating power is improved.When cervical orifice of uterus 1 declines, the area C increases with falling pressure, inner area
Domain air is extruded, and during spring shakes and rebounds, forms internal negative pressure, so that dovetail two sides " grabbing ground " is more firm, is increased
Strong isolation effect, can be avoided the air agitation that clean indoor air is flowed into from crack between a door and its frame.When cervical orifice of uterus 1 rises completely, B
Space possessed by area is maximum, to form a buffer area, further functions as the effect to surge chamber and toilet's isolation.
Specifically, the result advantage of deformation is: 1) elastic soft bottom frame touches ground, will not hurt ground；2) swallow
Tail deformation of bottom reduces requirement for the design of cervical orifice of uterus 1.
Technical solution of the present invention additionally provides a kind of concealed sealing crack between a door and its frame mechanical device.Transmission mechanism with hinge is ipsilateral sets
