Shape slot 2124 is on a vertical plane.
Embodiment 1: by taking 3 combination disks as an example.
As seen in figs. 5-6, Fig. 5 is that the utility model coded lock is prevented filling the opening state figure set in the deflated condition, Fig. 6
For the utility model coded lock it is anti-fill set open after liquefied gas flow graph, anti-fill of the utility model coded lock set opening
Mode is as follows:
Filled since coded lock is anti-and set combination disk in use and upset, therefore, it is necessary to first to coded lock it is anti-
The combination disk set is filled to control to original state (reset).
It is filled with the flat recess 2087 of convex 208 end in rotation drive device end alignment top on rifle, rotation drive device
Rotation drives convex 208 rotation in top, and the histogram block 2082 on top convex 208 is cooperatively formed with the linear type slot 2124 of coded shaft 212
The drive shaft of all combination disk positive and negative rotations.Pushing up convex 208 drives coded shaft 212 to rotate, in the column block for passing through coded shaft 212
(2123) it drives the lower part third convex block 2036 of end combination disk 203 to rotate first when rotated, keeps end combination disk multiple at first
, end combination disk 203 and the continuation synchronous rotary drive intermediate cryp-tographic disk reset of coded shaft 212 unexpectedly is then identical in continuation
Direction synchronous rotary drives head end combination disk 205 to reset, and sealing axis in this way drives each combination disk to be in original state.Further according to
The rotation angle of the setting of background program is reversely rotated for the first time by coded shaft to be made head end combination disk 205 be initially completed password to open
Open, coded shaft drive each combination disk unlatching direction of rotation and last time direction of rotation on the contrary, and so on, complete intermediate cryp-tographic
The unlatching of disk finally completes the unlatching of end combination disk 203.
At this point, the column block in the spacing breach and coded shaft of all combination disks corresponds, own under airflow acting force
Combination disk can be moved a certain distance towards airintake direction, and limit combination disk (210) can be limited in and prevent filling sealing surface by position-arresting disk at this time,
So, limit combination disk and head end combination disk hermetic separation, entire intake channel is opened under airflow acting force.Then it fills
The liquefied gas of air gun enters from the arch groove on top convex 208, then enters limit combination disk along top convex 208 and valve nozzle inner wall gap
Gap between outer wall and valve nozzle, liquefied gas enter the cavity between coded shaft and valve nozzle from arcuate socket, then from holding out against nut
Gap between 213 and valve nozzle enters in valve body main chamber, and last liquefied gas enters in cylinder for liquefied gas from valve body main chamber.
Embodiment 2: valve is prevented filling the state set by coded lock when illegal forced aeration.
As shown in fig. 7, combination disk is misaligned state, limit when coded lock is prevented filling and be set by illegal forced aeration
Disk closes the circular groove in the middle part of head end combination disk, and liquefied gas is prevented to pass through from circular hole gap, limits combination disk and head end combination disk
Overlapping, limit combination disk all block the arcuate socket in head end combination disk, and entire air flue is closed, and therefore, illegally fills shape by force
It is that can not inflate under state.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the patent model of the utility model
Enclose, equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, or directly or
It connects and is used in other relevant technical fields, be also included in the patent protection scope of the utility model.
