The invention relates to a technical field of locks, in particular to an anti-theft lock device with good anti-theft effect.

Generally, the conventional key locks are generally provided with a lockable core in a lock sleeve, the lock core has a key hole, and the lock sleeve has a plurality of elastic lock members between the lock sleeve and the lock core. The plurality of elastic lock members are normally locked by elastic force to restrict the lock core from rotating in the lock sleeve, and when the key is inserted into the key hole, the lock groove on the side of the key can be driven The plurality of elastic lock members are released from the limit for the lock core to rotate in the lock sleeve to achieve the purpose of unlocking. For example, the lock sleeve has a plurality of outer bead holes, and the lock core has a plurality of inner bead holes penetrating into the key holes and respectively communicating with the plurality of outer bead holes, the elastic lock member being included One of the outer bead holes and one outer locking bead are locked with one of the inner bead holes, and the plurality of outer locking beads and the plurality of inner locking beads are set to various lengths. Usually, the plurality of springs respectively position the contact surface of the corresponding outer locking bead and the inner locking bead in the outer bead hole or the inner bead hole, so that the locking core cannot be rotated in the locking core sleeve. And the purpose of locking up. When the key is inserted into the keyhole, the locking groove on the key can push the inner locking bead so that the contact surface of the inner and outer locking beads is just at the interface between the locking core and the locking sleeve, Then, the lock can be rotated in the lock sleeve to unlock the lock.

However, the conventional key lock is limited by the volume relationship, and the diameters of the lock bead and the inner lock bead are not large, so that the small key is inserted into the key hole by a word screwdriver, and then the lock core is strongly twisted, which is very It is easy to break the outer locking bead or the inner locking bead, and achieve the purpose of damaging the unlocking. Moreover, since the outer locking bead and the inner locking bead are only topped by the spring, the experience is small, as long as a wire is used to push the inner locking beads from the key hole, it is easy to The pressure of the inner locking bead is measured at the position where it needs to be pressed, and then unlocked. Therefore, the anti-theft effect of the conventional key lock is very poor.

In view of the above, the inventors have intensively conceived the above-mentioned problems, and actively researched and improved the trial and development to design the present invention.

The main object of the present invention is to provide an anti-theft lock device having a good anti-theft effect.

The plurality of spacers are sleeved on the locking plate shaft and spaced apart between the plurality of locking pieces. The plurality of spacers have a positioning edge for being disposed on the inner side wall of the outer casing so as not to rotate with the locking piece. The elastomer is disposed in the outer casing for providing the elastic force of the plurality of locking pieces and the plurality of spacers together. The lock core is rotatably coupled in the outer casing and has a key hole extending to one side in an open shape. The key can be inserted into the keyhole to rotate the lock core, and the key has a plurality of step edges respectively corresponding to the plurality of lock pieces. When the key is turned by an angle, the upper edge of the key can be respectively pushed to swing the plurality of locking pieces to a state in which the plurality of missing slots are in a straight line below the clamping piece; when the key is reversed back to the original position, the locking core The plurality of locking pieces can be pushed back to the original position. The knob lock mechanism comprises a knob, a driving member, a clutch block, a clutch cylinder, a C-shaped elastic piece and a linkage member. The knob is rotatably coupled to the outside of the housing and has a knob shaft extending into the housing. The driving member is rotatably sleeved on the knob shaft, and the peripheral mask has a card slot, and the opposite sides respectively have a sleeve and a protrusion. The upper end of the card sheet can be inserted into the card slot to be displaced to the carding position, and a guiding inclined surface is formed on both sides of the card slot for guiding the upper end of the card sheet smoothly to the driving member The circumferential surface is such that the card is displaced to the release position. A side wall of the sleeve has an axial groove. The clutch block is sleeved on the knob shaft and is rotatable by the knob shaft to rotate in the sleeve, and a circumferential surface of the clutch block has a groove. The clutch cylinder is disposed in the axial groove and the lower half is embedded in the groove of the clutch block. The C-shaped elastic piece is sleeved on the sleeve, and the elastic force is sufficient for the knob to rotate the driving member through the clutch block and the clutch cylinder to push the card to move to the release against the elastic force of the clamping elastic piece. position.

The linkage rod extends to the outside of the housing for driving a bolt mechanism. When the driving member is reversed by 360 degrees, the linking block can be pushed by the protruding post to rotate the linking member relatively 90 degrees to drive the locking mechanism to unlock and lock.

Thus, by the cooperation of the driving member, the clutch block, the clutch cylinder and the C-shaped elastic piece of the knob lock mechanism, the key lock mechanism can be used to unlock or lock the lock mechanism when the key lock mechanism is opened by the key. Therefore, the knob lock mechanism can be prevented from being strongly twisted, and the anti-theft effect is better. In particular, the plurality of locking pieces in the key lock mechanism do not use any elastic force to drive the swing to unlock or lock, but are completely driven by the step edge of the key and the lock core to swing or unlock or lock. The small system cannot use the wire to move the plurality of locking pieces to measure the unlocking position. Moreover, the key lock mechanism utilizes the elastic body to provide the elastic force of the plurality of locking pieces and the plurality of spacers together, and further prevents the plurality of locking pieces from arbitrarily swinging or being easily plucked, and further has an antitheft effect. . In addition, the plurality of spacers are spaced apart between the plurality of locking pieces, and the positioning edge of the plurality of spacers is placed on the inner side wall of the outer casing so that it does not rotate with the locking piece. The lock pieces can be operated separately without interfering with each other. In particular, when the knob is turned to the lower end of the card to be locked in the retaining groove of the plurality of locking pieces, the plurality of locking pieces cannot be swung, thereby preventing the rotation feeling and the lock by the knob The swinging feeling of the sheet opens the key lock mechanism, so that it can be further improved in theft.

When the lock core 35 is not rotated, the positioning block 15 is at one end of the positioning slot 352. When the lock core 35 is rotated 90 degrees, the positioning block 15 is at the other end of the positioning slot 352.

The knob lock mechanism 4 includes a knob 40, a driving member 41, a clutch block 42, a clutch cylinder 43, a C-shaped elastic piece 44, a sleeve cover sheet 45, a C-shaped buckle 46 and a linkage member 47. The knob 40 is rotatably coupled to the front side of the housing 10, and has a knob shaft 400 extending into the housing 10 from the pivot hole 12, and a ring groove 401 is formed at a distal end portion of the knob shaft 400. The driving member 41 is rotatably sleeved on the knob shaft 400, and has a slot 410 on the circumference of the driving member 41. The opposite sides respectively have a sleeve 411 and a protrusion 412. The card slot 410 is engageable with the upper end of the card sheet 21 to enable the card sheet 21 to be displaced to the carding position. A guiding slope is formed on each side of the card slot 410 for guiding the upper end of the card piece 21 to the circumferential surface of the driving member 41 so that the card piece 21 can be displaced to the releasing position. A side wall of the sleeve 411 has an axial groove 413. The clutch block 42 is sleeved on the knob shaft 400 and can be rotated by the knob shaft 400 to rotate in the sleeve 411. The clutch 42 has a groove 420 on the circumferential surface thereof. The clutch cylinder 43 is disposed in the axial groove 413 and the lower half is embedded in the groove 420 of the clutch block 42. The C-shaped elastic piece 44 is sleeved on the sleeve 411. The sleeve cover sheet 45 is rotatably sleeved on the knob shaft 400 on the open side of the sleeve 411 for restricting the clutch block 42, the clutch cylinder 43 and the C-shaped elastic piece 44 to the sleeve 411. The C-shaped buckle 46 is fastened in the annular groove 401 to fit the housing 10 for limiting the driving member 41 and the sleeve cover sheet 45 to the knob shaft 400. The linkage member 47 is rotatably coupled to the through hole 17 and has a pivot groove 470, a linkage rod 471 and a linkage block 472. The pivot groove 470 is rotatably sleeved at a distal end portion of the knob shaft 400. The linkage rod 471 extends from the through hole 17 to the outside of the cover body 11 for driving a bolt mechanism (not shown). The linking block 472 is protruded from the circumferential surface of the linking member 47. When the driving member 41 is reversed 360 degrees, the driving member 41 can be pushed by the protruding post 412 to reverse the positive locking member 47 by 90 degrees to drive the lock. The tongue mechanism is unlocked and locked.

Referring to the fifth figure, the key 36 is just inserted into the keyhole 350 in the locked state. At this time, the returning convex portion 351 of the lock core 35 is pushed against the locking side edge 314 of the plurality of locking pieces 31, and the plurality of locking pieces 31 are inclined at an angle, so that the upper missing groove 310 is not in a straight line. The card elastic piece 22 maintains the card piece 21 upward in the locking position by the elastic force thereof, and the upper end of the card piece 21 is caught in the card slot 410 of the driving member 41. The lower half of the clutch cylinder 43 is embedded in the recess 420 of the clutch block 42.

Referring to the sixth figure, it is pointed out that when the key 36 is rotated 90 degrees, the step 360 on the same will push the unlocking side 313 of the plurality of locking pieces 31 to swing the plurality of locking pieces 31 to The upper notch 310 is in a straight line on the lower side of the card sheet 21. At this time, when the knob 40 is rotated 270 degrees, the clutch cylinder 43 is pressed by the C-shaped elastic piece 44 to insert the lower half into the groove 420 of the clutch block 42. Therefore, the knob 40 can pass through the knob 40. The clutch block 42 and the clutch cylinder 43 drive the driving member 41 to rotate 270 degrees, so that the stud 412 just leans on one side of the linking block 472. At the same time, the upper end of the card sheet 21 is moved by the slot 410 of the driving member 41 along the guiding slope of the side to the circumferential surface of the driving member 41, so that the card sheet 21 is pushed downward. The release position is such that the card elastic piece 22 is elastically bent and deformed downward, and the lower end of the card piece 21 is embedded in the notch 310.

Referring to the seventh figure, it is pointed out that when the knob 40 is continuously rotated 90 degrees (that is, the knob 40 is rotated 360 degrees in total), the driving member 41 will continue to be rotated 90 degrees by the knob 40. At the same time, the stud 412 on the driving member 41 pushes the linking block 472 to rotate the linking member 47 by 90 degrees. Thus, the linkage rod 471 of the linkage member 47 can positively rotate the external bolt mechanism by 90 degrees to form an unlocked state.

Referring to the eighth figure, it is pointed out that in the above unlocked state, the driving member 41 is rotated by the knob 40, so that the card slot 410 is thus turned downward. Thus, the card sheet 21 is moved back to the carding position by the elastic force of the card shrapnel 22 from the release position. At this time, the upper end of the card sheet 21 is caught in the card slot 410, and the lower end is separated from the slot 310. In this way, the key 36 can be reversed by 90 degrees, so that the returning convex portion 351 of the lock core 35 pushes the locking side 314 of the plurality of locking pieces 31, so that the plurality of locking pieces 31 swing back to the original position, and then The keyhole 350 pulls out the key 36.

Referring to the figure IX, it is pointed out that when the lock is to be locked, the key 36 is first inserted into the keyhole 350 and then rotated 90 degrees, and the plurality of edges 360 on the key 36 are used to push the plurality of locks respectively. The unlocking side 313 of the 31 swings the plurality of locking pieces 31 to a state in which the notch 310 thereon is in a straight line on the lower side of the forming piece 21. At this time, when the knob 40 is reversed by 270 degrees, the clutch cylinder 43 is pressed by the C-shaped elastic piece 44 to insert the lower half into the groove 420 of the clutch block 42, so the knob 40 can pass the clutch. The block 42 and the clutch cylinder 43 drive the driving member 41 to reverse 270 degrees so that the stud 412 just leans on one side of the linking block 472. At the same time, the upper end of the card sheet 21 is moved by the slot 410 of the driving member 41 along the guiding slope of the side to the circumferential surface of the driving member 41, so that the card sheet 21 is pushed downward. The release position is such that the card elastic piece 22 is bent downward and deformed, and the lower end of the card piece 21 is inserted into the notch 310.

Referring to the tenth figure, it is pointed out that when the knob 40 is continued to be reversed by 90 degrees (ie, the knob 40 is reversed by 360 degrees in total), the driving member 41 will continue to be reversed by the knob 40 by 90 degrees, and at the same time The stud 412 on the driving member 41 pushes the linking block 472 to cause the linking member 47 to be reversed by 90 degrees. Thus, the linkage rod 471 of the linkage member 47 can reverse the external bolt mechanism by 90 degrees to form a locked state.

Referring to the eleventh figure, it is pointed out that in the above-mentioned upper lock state, the driving member 41 is rotated one turn by the knob 40, so that the card slot 410 is thus turned downward. Thus, the card sheet 21 is moved back to the carding position by the elastic force of the card shrapnel 22 from the release position. At this time, the upper end of the card sheet 21 is caught in the card slot 410, and the lower end is separated from the slot 310. In this way, the key 36 can be reversed by 90 degrees, so that the returning convex portion 351 of the lock core 35 pushes the locking side 314 of the plurality of locking pieces 31, so that the plurality of locking pieces 31 swing back to the original position, and then The keyhole 350 pulls out the key 36.

Referring to the twelfth and thirteenth drawings, it is pointed out that when the plurality of locking pieces 31 are twisted by wire or other items, the missing slot 310 is not in a straight line, so the knob 40 is rotated at this time. When the angle is θ (about 6 degrees), the knob 40 drives the driving member 41 to rotate by θ angle through the clutch block 42 and the clutch column 43. Thus, the card sheet 21 is pushed downward by the guiding slope of the card slot 410 until the lower end of the card sheet 21 is locked in the locking groove 311 of the locking pieces 31, so that the card sheet is made. 21 cannot move down to the release position. Therefore, the driving member 41 is caught by the upper end of the card piece 21 and cannot continue to rotate, and the purpose of unlocking cannot be achieved. At the same time, the plurality of locking pieces 31 can not be swung by the clamping of the lower end of the clamping piece 21, so that the small locking piece 31 can not be continuously pushed by the wire or other objects to test the swinging angle thereof, thereby achieving good Anti-theft effect. At this time, if the knob 40 is further rotated, the clutch cylinder 43 will be disengaged from the groove 420 of the clutch block 42 to open the C-shaped elastic piece 44 outward, so that the clutch block 42 is thus disposed on the driving member 41. The sleeve 411 is hollowed to prevent the knob lock mechanism 4 from being strongly damaged.

The elastic disengagement of the driving member 41, the clutch block 42, the clutch cylinder 43, and the C-shaped elastic piece 44 of the knob lock mechanism 4 is such that the key lock mechanism is first used by the key 36 when unlocking or locking. 3 After the opening action, the knob 40 can drive the locking mechanism to unlock or lock, so that the knob locking mechanism 4 can be prevented from being strongly twisted, and the anti-theft effect is better.

In particular, the plurality of locking pieces 31 of the key lock mechanism 3 do not utilize any elastic force of the elastic body when oscillating, but are completely unlocked and reset by the plurality of steps 360 of the key 36 and the lock core 35. The small lock piece 31 cannot be used to measure the unlock position of the lock piece 31 by using other objects such as a wire. Moreover, the key lock mechanism 3 uses the elastic body 33 to provide the elastic force of the plurality of locking pieces 31 and the plurality of spacers 32 together, and further prevents the plurality of locking pieces 31 from arbitrarily swinging or being easily plucked, thereby Further has an anti-theft effect.

In addition, the plurality of spacers 32 are spaced apart between the plurality of locking tabs 31, and the positioning edge 320 of the plurality of spacers 32 is disposed on the inner sidewall of the housing 10 so as not to follow the The rotation of the locking piece 31 is designed such that the locking pieces 31 can be operated independently without interfering with each other.

In particular, when the key lock mechanism 3 is not normally opened by the key 36, when the knob 40 is rotated, the clutch cylinder 43 is disengaged from the recess 420 of the clutch block 42 to cause the clutch block 42 to be driven by the drive member. The hollow portion is rotated so that the lower end of the card sheet 21 is caught in the retaining groove 311 of the plurality of locking pieces 31, so that the plurality of locking pieces 31 cannot be arbitrarily dialed. Thereby, the key lock mechanism 3 can be prevented from being opened by the rotation feeling of the knob 40 and the swing feeling of the lock piece 31, so that it can further have a better anti-theft effect.

In summary, since the present invention has the above advantages and practical value, and has not seen the same or similar technology published or disclosed before, the present invention has met the novelty and progressive requirements of the invention patent, and applied according to law. .
