[ detailed description ] of the invention
The invention is further described below with reference to the accompanying drawings:
the utility model provides a lock that key volume is big and can prevent technology from opening, its includes lock shell 100, is equipped with lock core 10 that can lock shell internal rotation in the lock shell 100, is equipped with on the lock core 10 and supplies blade 2 male blade holding tank 11 and supplies key male key holding tank 12, is equipped with a plurality of blades 2 in the blade holding tank 11, every blade 2 all be equipped with and supply key male blade groove 21, every blade 2's blade groove 21 constitutes and supplies key male key drive groove 3, is equipped with in the key drive groove 3 to be used for preventing technology from opening prevent dialling the piece and drive the key piece that the lock core rotated the realization switch lock with the key cooperation. Compared with the existing blade lock, the invention not only is provided with the key piece which is matched with the key to drive the lock core to rotate to realize the opening and closing of the lock, but also is provided with the anti-poking piece for preventing technical opening, and the key piece in the key driving groove 3 can be arranged at will due to the anti-poking piece, so that the key quantity is improved.
The blade groove 21 of the blade 2 of the present invention may be square, circular, irregular, etc.
As shown in fig. 5-8, when the key 8 is inserted into the key driving slot 3, since the width H of the key driving slot 3 is more than 1.5 times of the thickness F of the key 4, the height E of the key driving slot 3 is more than one third of the height F of the key 4, and although the width of the key driving slot 3 is much greater than the thickness of the key 4, due to the action of the anti-pulling member, when the technology is started, as long as one blade is pulled, the key moves along with the blade, and the key moves to drive other blades to move, so that a technical opener cannot judge which blade is moving, and the technical starting cannot be realized. In addition, the width of the key driving groove 3 is much larger than the thickness of the key 4, and the height E of the key driving groove 3 is larger than the height F of the key 4, so that the key piece can be arranged at different positions on the blade 2, and the length of the key piece can be selected more, thereby improving the key quantity.
The anti-dial member includes a first anti-dial block 51 provided on one side in the key driving groove 3, and a second anti-dial block 52 provided on the opposite side of the first anti-dial block 51 in the key driving groove 3. The first anti-setting block 51 and the second anti-setting block 52 may be provided on the same blade or different blades.
The first anti-dial block 51 and the second anti-dial block 52 are integrally structured with the blade 2, and the thickness of the first anti-dial block 51 and the second anti-dial block 52 is the same as the thickness of the blade 2. Therefore, a plurality of blades 2 arranged in the blade accommodating groove 11 can be tightly attached together, gaps are not generated between the blades, the number of the blades 2 in the blade accommodating groove 11 is increased, and the key quantity is improved.
One side of each blade 2 is provided with a blade spring slot 22 for the spring to snap into. The blade spring grooves 22 on each blade 2 can be arranged at the same position, so that only one spring is required to be assembled in the blade spring grooves 22, one spring drives the plurality of blades 2 to reset, the assembly quantity of the springs is reduced, and meanwhile, the difficulty of technical opening can be increased because one spring pushes the plurality of blades 2, and the situation that the blade cannot accurately sense when the technology is opened is solved.
The key member comprises one or more protrusions 6 arranged in the key driving groove 3, the protrusions 6 are arranged on the same blade or different blades, and the protrusions 6 can be sheet-shaped, block-shaped or columnar. The key member and the blade 2 are integrally formed.
The thickness of the bulge 6 is the same as that of the blades 2, so that a plurality of blades 2 arranged in the blade accommodating groove 11 can be tightly attached together, gaps are not generated between the blades, the number of the blades 2 assembled in the blade accommodating groove 11 is increased, and the key quantity is improved.
The invention can be that the lower side of the blade 2 is provided with an opening to form a notch 7 for inserting a key, and a key piece is arranged in a blade groove at the left side or/and the right side of the notch 7; the first anti-poking block 51 and the second anti-poking block 52 are arranged in the blade grooves on the left side and the right side of the notch 7.
The upper end wall of each blade 2 is also provided with a bumper slot 23 into which the bumper 7 snaps. The lock container body 1 is also provided with a bumper bar lifting groove 13 for lifting the bumper bar 7 on the lock container body 1.
The anti-poking part, the key part and the blade 2 are of an integrated structure, and can be formed by integrally punching and cutting a metal sheet, so that the anti-poking part, the key part and the blade 2 are more convenient to process.
A key 8 is provided with an anti-pulling groove for engaging with an anti-pulling member and a driving groove 83 for engaging with a key member.
The anti-dialing grooves comprise a first anti-dialing groove 81 which is arranged on one side surface of the key and matched with the first anti-dialing block 51, and a second anti-dialing groove 82 which is arranged on the other side surface of the key and matched with the second anti-dialing block 52. The first anti-poking groove 81 and the second anti-poking groove 82 may be a whole concave groove or may be formed by arranging a plurality of concave grooves in a row.
The distance between the first anti-shifting block 51 and the second anti-shifting block 52 is smaller than the thickness of the key 8, so that the difficulty of preventing technical opening can be further improved.
The driving groove 83 of the present invention may be formed by arranging a plurality of blind holes 831 in a row, and the size of the blind holes 831 is matched with the size of the key member.
The driving groove 83 of the present invention may also be a curved groove provided with at least one deepest concavity.
The inlets of the anti-poking groove and the driving groove 83 are respectively provided with an inclined surface 801, and the inclined surface 801 can be arranged on one side or the inclined surfaces 801 can be arranged on both sides, so that a key can be conveniently inserted into the key driving groove 3.
