Detailed Description
Example, see figure 1: a vehicle anti-theft lock assembly includes a housing 10 and a key 30. The housing 10 is generally stationary. The lock case 10 has a right-and-left through fitting hole 11 therein, and a lock core 20 rotatable in the fitting hole 11 is inserted in the fitting hole 11. For example, the lock core 20 is loosely fitted to the fitting hole 11. The lock core 20 has a key hole 21 therein with a left opening for the key 30 to pass through from left to right. Generally, the keyhole 21 is left-right through. In this embodiment, the key hole 21 and the key 30 have a square cross section.
Further speaking:
as shown in fig. 2, an upper limit groove 111 is provided at an upper portion of a circumferential side wall of the fitting hole 11, and a lower limit groove 112 is provided at a lower portion thereof, and both the upper limit groove 111 and the lower limit groove 112 extend in a longitudinal direction of the fitting hole 11.
As shown in fig. 3 to 7, the side wall of the key hole 21 is provided at an upper portion thereof with an upper insertion hole 211 extending upward to the upper surface of the lock core 20 and at a lower portion thereof with a lower insertion hole 212 extending downward to the lower surface of the lock core 20. Upper blades 22 which can move up and down are inserted into the upper insertion holes 211, and lower blades 23 which can move up and down are inserted into the lower insertion holes 212. In this embodiment, the upper row of blades 22 and the lower row of blades 23 are each flat plates having a square extension perpendicular to the direction of extension of the keyhole 21. The middle parts of the upper row of sheets 22 and the lower row of sheets 23 are provided with through holes 24. An encoding stage 241 is selectively provided on an upper side wall, a lower side wall, a front side wall or a rear side wall of the through hole 24. That is, only one sidewall of one perforation 24 is provided with the encoding stage 241, so that the encoding stage 241 is located either on the upper sidewall, or on the lower sidewall, or on the front sidewall, or on the rear sidewall of the corresponding perforation 24. The upper side of the upper row of sheets 22 is provided with an upper boss 221 extending upwards, and the lower side of the lower row of sheets 23 is provided with a lower boss 231 extending downwards.
As shown in fig. 8 and 9, the key 30 has a tooth socket 31 formed on each of an upper surface, a lower surface, a front surface and a rear surface. That is, the key 30 preferably has a square cross-section. The tooth grooves 31 located on the upper and lower side surfaces of the key 30 have variations in depth. That is, the bottom of the tooth socket 31 located on the upper and lower surfaces of the key 30 is recessed. The tooth socket 31 on the front and rear surfaces of the key 30 has a curvature change in the up-down direction. That is, the tooth grooves 31 on the front and rear surfaces of the key 30 are curved and varied.
More specifically:
the upper boss 221 is fitted to the upper limit groove 111, and the lower boss 231 is fitted to the lower limit groove 112. That is, in the initial state, the upper row of tabs 22 is located relatively upward, so that the upper boss 221 is caught in the upper limit groove 111, forcing the lock core 20 to be unable to rotate; meanwhile, in the initial state, the lower row of fins 23 is located relatively downward, so that the lower boss 231 is caught in the lower retaining groove 112, and the lock core 20 is also forced to be unrotatable.
The upper row of sheets 22 and the lower row of sheets 23 are provided with a pressure spring 25. The compression springs 25 give the corresponding upper row of blades 22 a tendency to move upwards and the compression springs 25 give the corresponding lower row of blades 23 a tendency to move downwards. That is, in the initial state, the upper row of blades 22 is positioned relatively upward and the lower row of blades 23 is positioned relatively downward by the pressing spring 25.
The socket 31 is fitted to the encoding stage 241. That is, the encoding stage 241 is caught at a portion of the corresponding socket 31 so that the corresponding upper or lower row 22 or 23 is located at an appropriate height. For example, the lower side wall of the through hole 24 of one upper row of sheets 22 has a coding platform 241, and the one upper row of sheets 22 corresponds to a position of the tooth socket 31 on the lower surface of the key 30; when the correct key 30 is inserted, the tooth socket 31 pushes down against the corresponding code table 241, and the corresponding upper row of tabs 22 will move downward by a certain distance against the pressure of the corresponding compression spring 25 until the upper projection 221 of the upper row of tabs 22 is disengaged from the upper limit groove 111, so that the lock core 20 may rotate. Similarly, the code platform 241 in the through hole 24 of a lower row of plates 23 is generally located on the lower side wall of the corresponding through hole 24, and the corresponding socket 31 is located on the lower surface of the key 30. In the case of the upper row 22 or the lower row 23, if the coding table 241 is provided on the front side wall in the through hole 24, the curved tooth socket 31 moves the corresponding coding table 241 corresponding to the tooth socket 31 on the front side surface of the key 30, so that the corresponding upper row 22 moves downward or the lower row 23 moves upward. Similarly, the coding 241 on the rear side wall of the through hole 24 corresponds to the tooth socket 31 on the rear side surface of the key 30. In fig. 4 to 9, the tooth sockets 31 on the upper, lower, front and rear surfaces of the key 30 are respectively identified by reference numerals 311, 312, 313 and 314, and their corresponding code platforms 241 are respectively identified by reference numerals 2411, 2412, 2413 and 2414.
Thus, the mutual unlocking rate of the blank tooth codes of the keys of the anti-theft lock component for the vehicle is greatly reduced. Meanwhile, the copying difficulty is improved, and the tooth form is unconventional. And, the tooth profile appearance is excellent.
Optimizing:
the right end face of the lock core 20 is provided with a linkage block 27 protruding rightwards, and the section of the linkage block 27 is non-circular. Meanwhile, the antitheft lock assembly for the vehicle further comprises a connecting plate 40 and a connecting piece 50. The middle part of the connecting plate 40 is provided with a linkage hole 41 which is sleeved on the linkage block 27, and the shape of the linkage hole 41 is the same as the section of the linkage block 27. And a hinge hole 42 is formed at the side of the connecting plate 40, and a connector 51 locked in the hinge hole 42 is formed on the connector 50. That is, after the lock core 20 rotates, the lock core can rotate with the connection plate 40, and then the connection member 50 moves up and down. The link 50 moves up and down, and then moves together with other members, thereby enabling unlocking and locking. This is conventional and will not be described further.
The lower portion of the link 50 is provided with a slider 52. The slide block 52 is provided with an E-shaped fixing member 53. That is, the slider 52 is connected to the associated unlocking member through the "E" shaped fixing piece 53.
A torsion spring 60 is provided between the lock case 10 and the lock core 20. That is, both ends of the torsion spring 60 are hooked on the lock case 10 and the lock core 20, respectively, so that the lock core 20 can be timely restored by rotating.
The sides of the upper and lower blades 22 and 23 are provided with a support 26 against which one end of the compression spring 25 abuts. Obviously, the upper insertion hole 211 and the lower insertion hole 212, which are inserted into the corresponding upper and lower blades 22 and 23, are provided with steps (not shown in the drawings) for supporting the other end of the compression spring 25, and the portion for penetrating the compression spring 25 has a receiving hole having a diameter larger than the thickness of the upper or lower blade 22 or 23.
In addition:
in the upper row 22, the code stages 241 having a part of the perforations 24 of the upper row 22 are located on the front side walls of the corresponding perforations 24, and the code stages 241 having a part of the perforations 24 of the upper row 22 are located on the rear side walls of the corresponding perforations 24. For example, different types of upper row of tabs 22 can be inserted into the upper socket 211 according to the model of the upper socket 211 of the milled lock core 20, and the type of the upper row of tabs 22 is different mainly in which side wall of the corresponding through hole 24 the assembling table 241 is located in the through hole 24. That is, whether the mount 241 in the upper row 22 is of the type 2413 in fig. 4 to 7 or of the type 2414 has different effects. Similar to the upper row of sheets 22 shown in fig. 1, there are a partial type 2413 and a partial type 2414 in addition to the type 2411 that it must have. Of course, the type of arrangement is not limited thereto. Therefore, the corresponding tooth codes are different, and the number of the milled teeth is increased; the tooth milling can be realized by knowing which type of the lock core 20 is selected, the effect is inconsistent, the number of the milled teeth is greatly increased, and the anti-copying effect is better.
Similarly, in the lower row of sheets 23, there may be some encoding stages 241 of the through holes 24 of the lower row of sheets 23 on the front side wall of the corresponding through holes 24, and some encoding stages 241 of the through holes 24 of the lower row of sheets 23 on the rear side wall of the corresponding through holes 24.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
