The below of described button separately all is equipped with back-moving spring; Described rocking arm, combination wheel, moving ratchet, quiet ratchet is equipped with back-moving spring on the relevant position separately; Described electric switch be installed in depression bar transverse bar the below and be fixed on the housing; Described electric switch is installed in the transverse bar below of L shaped reset button and is fixed on the housing;
The utility model makes coding flexibly owing to being provided with the ratchet intermittent drive mechanism and adopting code wheel, and this structure is the single-column type structure, symmetric arrangement, and feel and tin sound can't be decoded, and can realize automatically and the purpose of dual-use manual.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the ratchet intermittent drive mechanism assembling schematic diagram in the utility model structure.
With reference to accompanying drawing as can be known, the utility model by: resetting-mechanism, Cipher mechanism and opening mechanism are formed, it is characterized in that: a, Cipher mechanism: form the middle part that password button (24) is positioned at L shaped reset button (16) and release the button (1) by password button (24), rocking arm (15), combination wheel (20), moving ratchet (17), quiet ratchet (19), tooth axle (23), code wheel (21) and housing institutes such as (8), and place the top of rocking arm (15); The inclined-plane of password button (24) is slidingly connected with the corresponding one-tenth in inclined-plane of rocking arm (15), combination wheel (20) places in the arm body of rocking arm (15) below, moving ratchet (17) and the upper left ratchet of combination wheel (20) (202) resilient snap, quiet ratchet (19) is fixed on the housing (8) with the top-right ratchet of combination wheel (20) (202) resilient snap and with axle nail (32); The straight-tooth (201) of combination wheel (20) bottom and tooth axle (23) engagement, the internal tooth (211) of code wheel (21) becomes spline-like to plug together with tooth axle (23) end, and tooth axle (23) is fixed on the housing (8) by fixed head (5); B, opening mechanism: form by release the button (1), force-limit spring (4), depression bar (25), active latch (22), push rod institutes such as (7), releasing the button, (1) is equipped with force-limit spring (4) in the top of depression bar (25) and with the junction of depression bar (25), depression bar (25) inclined-plane becomes to be slidingly connected with push rod (7) right side, groove in the last lower inclined plane of push rod (7) and the active latch (22) becomes to be slidingly connected, and active latch (22) places in the loose slot of housing (8).
The below of described button separately all is equipped with back-moving spring (6), (14), (18).Described rocking arm (15), combination wheel (20), moving ratchet (17), quiet ratchet (19) is equipped with back-moving spring (29), (28), (31), (30) on the relevant position separately.Described electric switch (9), (10) be installed in depression bar (25) transverse bar (251) the below and be fixed on the housing (8).Described electric switch (11), (12) are installed in transverse bar (161) below of L shaped reset button (16) and are fixed on the housing (8).
Spring is compressed when outside brute force is exerted pressure, because release the button (1) is provided with force-limit spring (4), makes spacing the limit by housing (8) of button (1) stroke structure prop up, and has protected gear shaft not to be damaged.Active latch (22) drawn stem (7) control moves up and down corresponding with code wheel (21) outer breach.When code wheel (21) outer breach forwards active latch (22) correspondence position clockwise to, be decoded positions, when staggering the error code position.When password is correct, the outer breach of code wheel (21) is corresponding with active latch (22), release the button this moment (1) just can press depression bar (25) and move down, depression bar (25) inclined-plane promotes push rod (7) and is moved to the left, active latch (22) inserts in the breach of code wheel (21) under the effect of push rod (7) ramp, depression bar (25) is when moving down, transverse bar (251) on the depression bar (25) presses electric switch (9), (10) action, expose outside the housing (8) lower end of depression bar (25) simultaneously, promote other mechanical transmission mechanism action, thereby realized the purpose of the startup of outer electrical equipment by cipher control.Electric switch (11), (12) are subjected to L shaped reset button (14) control, play and stop effect, realize controlled electric reinstatement attitude.When electrical equipment damages, mechanical manual function should can be brought into play.Therefore, this structure can realize automatically and the purpose of dual-use manual, be the worthy companion of automatically controlled class lockset.
