Pinion cross shaft 9 can effectively be limited the raised line fixed, and pass through inner wall by the lateral notch of setting by touching
It can preferably keep being bonded ability with pinion cross shaft 9, prevent poor contact and lead to the response rank of response structure
It reduces, due effect cannot be reached.
The touch device 4 includes touch-control pedestal 15 and triggering rod 16, and the touch-control pedestal 15 is in asymmetric inverted " t " word
Type, 15 side of touch-control pedestal are fixed with mounting rack 17, and the mounting rack 17 is fixedly mounted by two fixing bolts 18
On car cab 3, the triggering rod 16 is laterally vertically connected on 15 other side of touch-control pedestal by hinge 19, pushes up in triggering rod 16
Portion is fixedly installed with touch-control probe 20, and is equipped with reset spring 21,21 both ends of reset spring point in 16 two sides of triggering rod
It is not fixedly mounted on 16 top of 15 outside of touch-control pedestal and triggering rod, limited post 22 is fixedly installed with inside reset spring 21,
The limited post 22 is fixedly mounted on touch-control pedestal 15, and the length of limited post 22 is equal between touch-control pedestal 15 and shell 5
Distance 4/5, be used in conjunction with each other, enabled to more quasi- when touch-control by triggering rod 16 and touch-control probe 20
Really, it can prevent workpiece or other equipment inside due to elevator from surprisingly touching and safety device is caused to be judged by accident, energy
Enough improve the reliability of device, and reset spring 21 enables to device that can quickly reset after removing, prevent due to
Device blocks and safety device is caused to fail.
Preferably, the shell 5 is made of a cuboid and sphere, and sphere is close to 3 side of car cab；It is described outer
It is also equipped with tongue lockhole 12 on compartment door 2, external control tongue 13, and the shape of external control tongue 13 are connected in the tongue lockhole 12
Occlusion corresponding with external connection shank of the key, is carved with anti-fake correction line inside the external control tongue 13, and anti-fake correction line and outer

The end of slot 14 and block tongue 10 corresponds.
In addition, it may further be preferable that as shown in fig. 6, being equipped with anti-bias detection between the touch ball 1 and touch device 4
Device 23 prevents from leading to two structures pair due to long-term use convenient for detecting the positional relationship of touch ball 1 and touch device 4
Position is answered to deviate, thus generate poor contact and cause to protect structure that cannot trigger in time, the anti-bias detection device 23
It is fixedly mounted on 4 outside top of touch device or bottom, the anti-bias detection device 23 includes fixed underpan 24, the fixation
24 side of chassis is vertically fixedly installed with calibration detection needle 25, the top of the calibration detection needle 25 and 1 appearance face paste of touch ball
Splice grafting touching, and it is equipped with detection LED line circle 26 in the outside of calibration school detection needle 25, the calibration detection needle 25 is being located at detection
Part inside LED line circle 26 is made of permanent magnet, it is described detection LED line circle 26 by winding annular in shape enameled wire 27 and with
The LED lamp tube 28 that enameled wire 27 is directly connected to forms, and the light that the LED lamp tube 28 issues is flashing feux rouges.
The working principle of anti-bias detection device 23 is explained further: when the position of touch ball 1 and touch device 4 occurs partially
From when, will be triggered in advance when elevator runs to this part calibration detection needle 25, and due to not predetermined position triggering school
Quasi- detection needle 25, then the position of calibration detection needle 25 will deviate, and due to being permanent-magnet structure, magnet occurs movement and cuts
Electric current will be generated by cutting detection LED line circle, so that the LED lamp tube of flashing feux rouges issues alarm light, in this way in the normal of elevator
In operation, directly it can easily can detect whether protective device is deviateed by the gap between two compartment doors,
It is convenient for subsequent maintenance.
Further, concrete operating principle and process of the invention: when car cab 3 drop to it is corresponding with enclosure door 2
When position, the touch device 4 for being located at car cab 3 touches setting and generates extruding force in wall touch ball 1, makes to be sleeved on touch ball
The spring 8 on centre pinion 7 on 1 inside center bearing 6 is compressed, while centre pinion 7 generates rotation, and it is fixed in horizontal axis to drive
Pinion cross shaft 9 in the slot 11 of position is allowed to jump out 14 rear cargo door of enclosure door lower part card slot by pinion cross shaft 9 10 post-tensioning of block tongue
It can be opened automatically；When car cab 3 leaves corresponding position of touch, the spring 8 in touch ball 1 returns to original
Position generates reaction force, stretches out block tongue 10, blocks back in enclosure door lower part card slot 14, enclosure door 2 would not be beaten automatically
It opens.
In addition, in the present invention, it is also necessary to further explanation: when elevator reparing, needing to open respective storey
Enclosure door 2 when, only corresponding connection shank of the key need to be inserted into the tongue lockhole 12 that be arranged on wall, set be anchored to external control tongue 13
Rotation, will with compartment outdoors door mutually touch when as, enclosure door 2 can be opened easily.If elevator door is opposite opened, need
Product of the present invention is set at two enclosure doors；If it is single open-type, then the setting present invention need to only be produced at the first fan enclosure door
Product.
In conclusion the main characteristic of the invention lies in that: it is an advantage of the invention that Purely mechanical working principle, is not related to electricity
Related contents, the misoperation probabilities as caused by power supply, computer such as source, computer control are zero, have prevented to miss due to enclosure door completely
It opens and causes personnel and fall the generation of casualty accident, and can be reached in determining trigger condition by mechanical processing
It to the purpose executed instruction, can prevent from leading to elevator faults due to software bug, or even occur also to exist when opening carriage
The extreme cases such as operation, and there is self-protection and detection deviation capability, device reliability of operation can be greatly improved, this
Invention applicability is extremely wide, and expansibility is strong, and either new clothes or Late reformation cost are all extremely cheap, and market prospects can
It sees.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
