Passive lever key and lock

A passive lever key and a lock, in particular, a blade key, two wings are formed with a wide and different order of left and right symmetry, and at least one step of the two wings is provided with a through hole perpendicular to the spoon, and each through hole is inserted Passive rod with limited displacement, the passive rod is struck against the trajectory in the blade key rotation trajectory and the other end protrudes to the preset position adjustable segment lock plate and blade to achieve the purpose of closing/unlocking, with pairing code The number can avoid the phenomenon of repetition, and it can eliminate the unscrupulous use of any kind of unlocking tool to illegally unlock the lock, which is the breakthrough designer of the blade key and lock.

The commercially available blade lock (2) combination (see Figures 11~13) is widely used by the public because it has the advantage of being less susceptible to electric drills directly from the keyhole (27), and its structure is composed of a blade. The key (1) and the corresponding blade lock (2) are formed, and the inserting end (11) of the key lever (10) of the blade key (1) is formed with two wings (12) which are diagonally symmetrically expanded to the left and right. The side of the flap (12) is formed with a plurality of different steps (13), and the blade key (1) is inserted into the key hole (27) of the door panel (91) of the door panel (91) with the insertion end (11). The center of the plate (12) corresponds to the sawtooth groove (40) provided at the end of the blade lock (2) lock plate (4) near the key hole (27), and the blade key (1) two wings (12) front and rear The plate area corresponds to the front and rear row of blade plates (3) (also called row plates), and each blade plate (3) is provided with at least 2 long holes (30), and a password such as a car gear is formed in the middle of the plate surface. Zone (32), and the upper part of each blade plate (3) is provided with an elasticity The piece (34) is displaceable and returnable when it is pushed against the lock case (20) by the blade key (1), and the key hole is provided in the center of the inner surface of the blade lock (2) lock case (20) (27) And corresponding to the blade plate (3) long hole (30) forming a leg (21) for wearing the sleeve and then being sleeved by the sleeve (38), and the lock case (20) is provided with a segment lock plate hole on the side of the door frame (22) The locking plate (4) is extended and locked, and a locking tongue hole (23) is provided at a position slightly below the same side of the segment locking plate hole (22) for being fixed to the cross bar (24) by the spring (25). The locking tongue (26) extends out of the engaging door panel (9) (see Fig. 6), and the locking shell (20) corresponds to the position of each of the front and rear row of blade plates (3) (30) The foot column (21) is fixed to be fixed: in practice, the lock cover (91) and the door panel (9) door hole (90) of the door panel (9) are sequentially passed through the locker by the blade key (1). When the conduit (92) and the keyhole (27) covering the cover (29) of the lock case (2), the center of the blade key (1) flap (12) abuts against the contact lock plate (22) and its steps (22) corresponding to the front and rear row of blade plates (3), the blade key (1) will rotate the compression spring (25) when the right hand rotates, and the lock tongue (26) will be unlocked by disengaging the door frame; Outdoor with blade key (1) When the keyhole (27) is left-handed, its two wings (13) are changed from the horizontal 0° state to the vertical 90°, and the blade key (1) of the two wings (12) is nearly 90 degrees during this rotation. The card is inserted into the groove (54) of the segment lock plate (52) for lateral displacement and locking in the direction of the door frame, and each lock is locked by 180° (a commercially available 3-5 lock); another blade key ( 1) The two steps (13) of the two wings (12) abut against the front and rear rows of blade plates (3) compressing the elastic members (34) upwards, and at the same time the blade keys (1) are turned 90° while allowing the blade keys (1) Check the correctness of the password area (32) of the blade plate (3); the inconsistency is often rotated and unlocked by the multi-module blade key (1), so as long as there is enough matching one by one, the blade lock (2) It is not a difficult lock. The creator has developed this creation after years of research. The purpose is to provide a passive rod (17) that uses the limited displacement to resist the blade lock (2) trajectory. The plate (6) track (60) is correct The core code position is closed/unlocked.

The preferred embodiment of the passive lever key and lock (see Figures 1 and 2) is that the number of pairing codes for the blade lock (2) is too small to be repeated (i.e., the same blade key (1) can be opened. Different sets of blade locks (2), and to avoid unscrupulous use of any type of unlocking tool to illegally unlock, the blade key (1) of the key lever (10) insertion end (11) formed with left and right outer expansion and bilateral symmetry The two wings (12) and the two wings (12) form a plurality of different steps (13) on the side of the plate, and at least one step (13) of the two wings (12) is provided with the vertical direction of the spoon (10) In the through hole (15), a passive rod (17) with a limited displacement is placed in each through hole (15), wherein the length of the passive rod (17) is greater than the depth of the through hole (15), and the center of the shaft is formed equal to The length of the displacement is reduced (18), and the blade key (1) of the key lever (10) corresponds to the central rod of the passive rod (17) (18) is drilled with a pin hole (14), when the passive rod (17) When the two-wing plate (12) is inserted into the through hole (15), a pin (16) is forced by the pin hole (14), because the length of the tapered portion (18) of the passive rod (17) is larger than the outer diameter of the pin (16) And when the limit displacement is reached, the passive lever (17) is rotated when the blade key (1) is rotated. The side will be in contact with the inner track plate (6) of the blade lock (2) and adjusted to the preset position----the other end protrudes out of the through hole (15) and the preset blade on the upper blade lock (2) The board (3) reaches the correct core code position and closes/unlocks.
