Described wheel support 39 is provided with elastic force and determines hock 391, and described elastic force is determined hock 391 and fit in the inter-tooth slots place of described all gears 33.
Girder steel self-locking device 5 comprises girder steel 51, translation kelly 52, rotation discount 53, torsion spring 54, cam pin 55 and spacer pin 56; Described cam pin 55 is connected in described rotation discount 53, and described torsion spring 54 is connected between described rotation discount 53 and cam pin 55, and described translation kelly 52 is connected in described cam pin 55; One end of described girder steel 51 is provided with buckle slot 57, and the other end of described girder steel 51 is provided with long recess 58, and described translation kelly 52 coordinates clamping with described buckle slot 57, and described spacer pin 56 coordinates and offsets with described long recess 58.
Described linkage 4 comprises coding 41, stage clip 42, pivoted arm 43 and pulls out tire 44; Described stage clip 42 is socketed on the lower end of described coding 41, described stage clip 42 is connected to described housing 1, described coding 41 upper ends covers are connected in described girder steel 51 and are provided with one end of long recess 58, one side of described coding 41 is provided with a coding arm hole 411, described pivoted arm 43 is rotationally connected with described wheel shaft A37, one end of described pivoted arm 43 is connected with a described coding arm hole 411, the other end of described pivoted arm 43 with described in pull out tire 44 and be connected, described in pull out tire 44 with described in pull out gear 35 and be meshed.
In the time that the girder steel 51 of girder steel self-locking device 5 is depressed to housing button hole 7, under the torsion of torsion spring 54, translation kelly 52 blocks the buckle slot 57 of girder steel 51, and girder steel 51 is in self-locking state.In the process of pressing at girder steel 51, stage clip 42 plays the effect of pretension always to girder steel 51, and topping bar of long recess 58 played and be pressed into position-limiting action with spacer pin 56 simultaneously.Girder steel 51 promotes coding 41 and moves down, and a coding arm hole 411 will drive pivoted arm 43 around wheel shaft A37 rotation, and the tire 411 that pulls out that is positioned at pivoted arm 43 other ends pulls out gear 35 by promotion and rotates.Now, girder steel self-locking device 5 starts to promote mechanical coding device 3 by linkage 4 and carries out mechanical coding.
The coding of mechanical coding device 3 is orderly and unique, it is by following process implementation: when pulling out tire 411 and promoting to pull out gear 35 and rotate, affixed owing to pulling out gear 35 with the first encoder gear group 310, the first encoder gear group 310 with pull out gear 35 and synchronize rotations, this rotation is forward rotation.The number of teeth of pulling out gear 35 is 10, is pulled out tire 411 and drives and just in time rotate a circle for 10 times, and the first encoder gear 31 upgrades 10 subcategory numbers simultaneously.When the first encoder gear 31 upgrades 10 subcategory numbers, be after the first encoder gear 31 rotates a circle, be positioned at the once opportunity driven intermediate drive gear 36 of bidentate 34 of the first encoder gear 31 opposite sides, intermediate drive gear 36 is position encoder gear group 320 after power synchronous is passed to first group by wheel shaft B38, when position encoder gear group 320 after first group is upgraded 10 subcategory numbers, after rotating a circle, position encoder gear group after the bidentate 34 of position encoder gear group 320 passes to second group by intermediate drive gear 36 by power synchronous after first group, so analogizes.Realize front-wheel and upgrade 10 codes, trailing wheel upgrades 1 code, and ratio is 10 yards: 1 yard.On anti-repeated code check plate 621, be provided with stopper 622, stopper 622, for stopping the bidentate 34 of last rear position of group encoder gear group 320, makes last rear position encoder gear 32 forward rotation angles be no more than 360 degree.Anti-reverse pawl 61 on wheel shaft B38, hooks the gear teeth that pull out gear 35, and it can not be rotated backward.By the cooperation of said mechanism, the coding of mechanical coding device 3 can guarantee that whole coding is unique unduplicated in order.The aobvious one yard of being aligned of each encoder gear demonstrates four codings at transparent coding display window 12, calculates and can have 10000 orderly and unique codings by ratio 10:1.The elastic force that wheel support 39 arranges is determined hock 391, and elastic force is determined hock 391 and fit in the inter-tooth slots place of all gears 33, and the rotation of each encoder gear must overcome elastic force and determine the elastic force of hock 391 and can rotate, and guarantees thus the stability of coding.
Due to abnormity design and the inner special setting of rotation discount 53 keyholes, only have the key of joining by spy to insert, and need impose the torsion that external force overcomes torsion spring 54 to key can make its rotation and pull inner translation kelly 52 to exit the buckle slot 57 of girder steel 51 by the cam pin 55 on rotation discount 53, thereby can remove the self-locking state of girder steel 51, realize girder steel 51 and eject housing button hole 7, getting out of a predicament or an embarrassing situation of long recess 58 played ejection position-limiting action with spacer pin 56.In the time that girder steel 51 self-locking states are opened and again carry out self-locking, mechanical coding device 3 produces again new mechanical coding by said process, and original old mechanical coding is eliminated.Be to be consistent with No. ID of passive electronic label system 2 due to the mechanical coding of original state, just can know whether girder steel self-locking device 5 was opened so read contrasting with mechanical coding for No. ID of passive electronic label system 2 by reader.If No. ID of electronic labelling system 2 is consistent with mechanical coding, represent that girder steel self-locking device 5 is not opened; Inconsistent words, represent that girder steel self-locking device 5 has been opened, can also know by the contrast of coding the how many times that was opened.
Mechanical coding safety type RFID passive electronic label of the present invention, adopts reliable ripe technology, is connected by mechanical coding device 3 and girder steel self-locking device 5, passively mechanically realizes the each self-locking of girder steel 51 and all synchronously produces unique new coding in order; If carry out again self-locking after the girder steel stolen solution of 51 self-locking state robber in way, new mechanical coding produces and the elimination of former mechanical coding, and contrast with mechanical coding by the data that read passive electronic label system 2, can know girder steel 51 self-locking states stolen untiing on the way; Improve passive electronic label in the market, cannot send to situations such as moving, steal, change the limitation of security information because lacking active safety circuit system.
