The specific embodiment
Below in conjunction with accompanying drawing the utility model mechanical code lock is described in further detail.
Such as Fig. 1-Fig. 5, the utility model mechanical code lock, comprise coded lock body 8, be provided with pushing piece 5 and some password keys at the coded lock body, such as Fig. 4, Fig. 5, password key 81 is arranged, password key 82, password key 83, password key 84, password key 85 and password key 86, each password key is equipped with a cover press button mechanism, and each press button mechanism includes tooth bar 1 and gear 2, be provided with breach 21 at gear 2, be provided with the driving cog that is meshed with gear 2 and can the driven gear rotation when password key is pressed action at tooth bar 1, the coaxial installation of gear on each password key, be provided with the boss that just coincide with notch gear at pushing piece 5, open lockset when wherein pushing piece 5 is by the cogged breach of institute.Each press button mechanism also comprises external force button piece 4, Location resilient piece 3, side in the tooth bar bottom is provided with ratchet, Location resilient piece 3 is installed in the rack ratchet side, external force button piece 4 is installed from top to bottom successively with tooth bar, wherein driving cog is located at the tooth bar bottom and is positioned at the relative side of ratchet, ratchet comprises the first ratchet and the second ratchet that is arranged in order from bottom to top, in the tooth bar bottom tooth bar back-moving spring 6 is installed, at external force button piece 4 button back-moving spring 7 is installed, the bottom of external force button piece 4 can with tooth bar 1 top interlock, when wherein pressing external force button 4, tooth bar 1 also can be followed the button direction of motion and be done relative linearly operating, shell fragment 3 blocks until ratchet is positioned, and the relative position of the breach 21 of gear 2 changes the motion control that then realizes pushing piece 5 by the driving cog meshing gear rotation on ratchet opposite.
Top in the rack ratchet side is provided with first order step, second level step from bottom to top successively, the end face on the top of driving cog is shaped to first order step surface, can fit with the first order step on tooth bar top or second level step in the bottom of external force button piece 4, the first ratchet or the second ratchet phase clamping of corresponding Location resilient piece 3 and tooth bar bottom.Have 4 driving cogs on the tooth bar 1.When gear 2 meshes with tooth bar lower end the first driving cog, be vacant password state; When second driving cog of gear 2 and tooth bar lower end meshed, tooth bar and button were got back to initial position by spring, and gear 2 rotates under the transmission of tooth bar 1, and the breach on the gear is also shifted one's position thereupon, blocks the motion of pushing piece 5, for the password state is set.
Be provided with inclined plane part and be connected planar portions at Location resilient piece 3, Location resilient piece is by connecting planar portions and the first ratchet or the second ratchet phase clamping.
Motion principle: because tooth bar 1 is that 4 driving cogs and another 2 ratchets then are that the first ratchet and the second ratchet form by 4 little teeth, 4 little teeth can separate with meshing with gear 2,2 ratchets and the Location resilient piece 3 of another side are meshing, Location resilient piece 3 control tooth bars 1 upper-lower position.Gear 2 is not in the situation that there is password meshing with first tooth of tooth bar 1, such as Fig. 1.Breach on the gear 2 is just aimed at the boss on the pushing piece 5, and pushing piece 5 can slide along breach, and such as Fig. 4, lockset can be opened.When external force is pressed external force button piece 4, tooth bar 1 can be along the motion of button direction, tooth bar 1 driven gear 2 rotates, the breach of gear 2 also rotates thereupon, such as Fig. 2, the boss on the pushing piece 5 can't lead to the breach on the gear 2 like this, and pushing piece 5 can not move, such as the button 84 of Fig. 5, lockset can not be opened.
The replacing of password and setting, the escape key makes tooth bar 1 and gear 2 separately such as the button 81 of Fig. 5 by interlinked mechanism, then presses tooth bar 1, makes Location resilient piece 3 can effectively block rack ratchet.Then rotate the escape key, make second tooth and gear 2 engagements on the tooth bar 1, again by reset key, make button 84, tooth bar 1, gear 2 resets, such as Fig. 3, thereby the breach on the gear 2 also becomes different angles directed, boss on the pushing piece 5 is blocked by gear 2, can not move, such as Fig. 5 button 85, lockset can not be opened, and button 85 just has been arranged to password like this.Only press this key the breach that makes on the gear 2 and the boss on the pushing piece 5 when same position, pushing piece 5 could move, and lockset could be opened.
The escape mode:
1) with other interlinked mechanisms gear 2 and tooth bar 1 are separated first, such as Fig. 5.
2) pressing tooth bar 1 can be position shown in Figure 2 or position shown in Figure 3.
3) again gear usefulness interlinked mechanism tooth with in tooth bar, such as Fig. 4.
4) press reset key, tooth bar can reset by driven gear, and notch gear can rotate thereupon, reaches the escape purpose.
