Fig. 4 is the structural representation of the coding slide plate among Fig. 1.

Fig. 5 is the structural representation of password push pedal among Fig. 1.

Fig. 6 is the structural representation of lockhole plate washer among Fig. 1.

1 is shell among the figure, 2 is shell lockhole opening, 3 are password promotion groove, 4 are password numbering mark, 5 is lockhole plate washer locator slide, 6 is the password locking pressing plate, 7 is the password push pedal, 8 is password push pedal handle, 9 is password push pedal trundle, 10 is password push pedal positioning reed, 11 is the lockhole plate washer, 12 are coding slide plate locator slide, 13 are the coding square hole, 14 is the password locating hole, 15 is plate washer lockhole opening, 16 is lockhole plate washer push button, 17 is the password positioning ball, 18 are the coding slide plate, 19 are coding slide plate locating hole, 20 are the coding groove, 21 is password positioning ball stage clip, 22 is the stage clip riveting point, 23 is lockhole plate washer chimb, 24 is the shell fixed screw holes.

Only establishing a group coding sign indicating number position among the figure is 4, can protect two lockholes, requires to establish many group codings according to password encryption in the implementation process, and the sign indicating number position of every group coding also can arbitrarily be set, and the protection lock hole count also can be chosen wantonly.The utility model embodiment is a security door lockhole protective device; with principle in the accompanying drawing; structure is all identical; just code set increases to 3 groups; 3 group coding slide plates (18) promptly are set on one group of lockhole plate washer; password push pedal (7); password positioning ball (17) and affiliated separately annex; the sign indicating number position increases to 10; be that each group password locating hole (14) is 19 (sign indicating number position * 2-1) every group of password numbering mark (4) is 10, and encoding board password locating hole (19) still is 2, and every group of password positioning ball (17) also is two; the cipher code set number is 1000 groups, and the lockhole of protection (2) also is 2.

Password positioning ball (17) adopts the ordinary bicycle steel ball, password push pedal positioning reed (10), password positioning ball stage clip (21) adopts the spring steel plate punching press to make, other all parts all adopt the general steel plate punching press to make, rivet is adopted in spring steel plate and steel plate junction, connects between steel plate to adopt spot welding to connect.

Lockhole plate washer (11) is shifted to the left side when the lockhole closed state; two lockholes all are closed; push pedal trundle this moment (9) has shifted out the right side that coding groove (20) enters coding square hole (13); password positioning ball stage clip (21) entered password positioning pressuring plate (6) below make password positioning ball (17) extremely fixing coding slide plate locating hole (19) and password locating hole (14); thereby coding slide plate (18) can not be moved; mobile password push pedal handle (8) drive password push pedal (7) and push pedal trundle (9) move it the position outside password; lockhole plate washer this moment (11) can not move; play a protective role; each is organized password and all aligns when true; promptly the push pedal trundle (9) of each group moves to right to promoting lockhole plate washer push button (16) drive lockhole plate washer (11) at once to the right with coding groove (20); left side shell lockhole opening (2); because plate washer moves to right and exposes; the relative lockhole that makes with plate washer lockhole opening (15) of right side shell lockhole opening (2) exposes; built-in lock can normally use; at this moment; push pedal trundle (9) enters coding groove (20) again because password positioning ball stage clip (21) moves to right and is not subjected to the restriction of password positioning pressuring plate (6); reset password as need and can promote the upper and lower displacement of password push pedal handle (8) drive push pedal trundle (9) drive coding slide plate (18); whenever moving a steel ball (17) beats once; play the role of positioning simultaneously; setting finishes and remembers new password; promote lockhole plate washer push button (16) sealing keyhole left; promote the password push pedal handle (8) of each group again; upset password, finish overall process.Password push pedal positioning reed (10) effect has the scale sense also to play anti-fall effect simultaneously when being to promote password push pedal handle (8); lockhole plate washer chimb (23) also seals shell fixed screw holes (24) when the lockhole closed state; make other people can't back out screw, play the Global Macros effect.
