Detailed Description
As shown in fig. 1A and 1B, the present invention is a rotary knob lock 900 that is easy to operate and is not damaged by forcibly rotating the rotary knob 100. In a preferred embodiment, the turn button lock 900 of the present invention is for use in a cabinet 880, wherein the cabinet 880 has a door 881, and the user can rotate the turn button to rotate the locking member 500 to a locking position 581, shown in fig. 1A, where the door 881 is not opened, and an unlocking position 582, shown in fig. 1B, where the door 881 is opened. In various embodiments, however, the knob lock 900 may also be used as a case lock, door lock, glass door lock, window lock, furniture lock, etc.
As shown in the embodiment of fig. 2A and 2B, the knob lock 900 includes a knob 100, a driving cylinder 200, a rotary member 300, a connecting cylinder 400, a locking member 500, and a first core 601. The knob 100 is rotatable about a first axial direction 801. That is, the knob 100 is rotated with respect to an axis 810 extending in the first axial direction 801. The knob 100 rotates along a plane formed by the second axis direction 802 and the third axis direction 803, and the first axis direction 801, the second axis direction 802 and the third axis direction 803 are orthogonal.
As shown in fig. 2A and 2B, the driving cylinder 200 is engaged with the knob 100 and rotates together with the knob 100 about the first axial direction 801. More specifically, in the preferred embodiment, the inside 111 of the top portion 110 of the knob 100 has an engaging member 112, the top portion 210 of the driving cylinder 200 has an engaging hole 212, and the engaging member 112 is engaged with the engaging hole 212. This allows the drive cylinder 200 to engage with the inside of the knob 100. However, in various embodiments, the drive barrel 200 can be engaged with the knob 100 in various ways depending on manufacturing, design, or use requirements.
As shown in fig. 2A and 2B, the rotary member 300 is disposed in the driving cylinder 200 and can rotate around a first axial direction 801. The connecting cylinder 400 is provided on the other side of the rotary member 300 with respect to the knob 100, is connected to the rotary member 300, and rotates in conjunction with the rotary member 300 about the first axial direction 801 as an axis. The locking member 500 is disposed on the other side of the connecting cylinder 400 opposite to the knob 100, and rotates together with the connecting cylinder 400 about the first axial direction 801. The first lock core 601 is disposed beside the connecting cylinder 400. When the first lock core 601 is in a locked state, the rotation of the rotary member 300 is restricted by the first lock core 601, and the rotary knob 100 and the driving cylinder 200 can rotate relative to the rotary member 300; when the first lock core 601 is in the unlocked state, the rotation of the rotary member 300 is not restricted, and the rotary knob 100 rotates to drive the locking member 500 to rotate to the unlocked position 582 where the door 881 can be opened. The first lock cylinder 601 is preferably, but not limited to, a combination lock cylinder.
More specifically, as in the embodiment shown in fig. 2A, a side surface 410 of the connector barrel 400 has a connector barrel recess 411. The first cylinder 601 has a lock shaft 610, and one end 611 of the lock shaft 610 is movably inserted into the connector recess 411. As shown in fig. 3A and 3A-1, the inner wall 220 of the driving cylinder 200 has a driving recess 240, and the skirt 320 of the rotating member 300 has an elastic member 340 abutting against the inner wall 220 of the driving cylinder 200 and capable of being snapped into the driving recess 240.
In the embodiment shown in fig. 3B, when the first lock cylinder 601 is in the locked state, the movement of the lock shaft 610 is restricted, and one end 611 of the lock shaft 610 is inserted into and held by the connecting cylinder recess 411 (see fig. 2A), so that the rotation of the connecting cylinder 400 and the rotary member 300 is restricted by the first lock cylinder 601. At this time, when the knob 100 (see fig. 2A) is rotated by an external force, the driving cylinder 200 is also rotated based on the interlocking relationship. However, since the rotation of the rotary 300 is restricted by the first core 601, the knob 100 and the driving cylinder 200 rotate relative to the rotary 300. In the embodiment shown in fig. 3B-1, the elastic member 340 will bend inward the rotating member 300, separate from the driving recess 240, and abut against the inner sidewall 220 at a position other than the driving recess 240.
As shown in fig. 3C, when the first lock core 601 is in the unlocked state, the movement of the lock shaft 610 is not restricted, that is, the one end 611 of the lock shaft 610 can be separated from the connector recess 411, and the restriction of the rotation of the rotary member 300 is released. At this time, if the knob 100 (see fig. 2A) is rotated by an external force, as in the embodiment shown in fig. 3C-1, the driving cylinder 200 is also rotated based on the interlocking relationship, and the rotating member 100 is also rotated by being inserted into the driving recess 240 through the elastic member 340, so as to further rotate the connecting cylinder 400 and the locking member 500.
In other words, if the user rotates the knob 100 when the lock cylinder 601 is in the unlocked state, such as when the password is correct, the knob 100 can rotate the driver 500. If the user still forcibly rotates the knob 100 when the lock core 601 is in the locked state, such as a wrong password, the knob 100 can be rotated without damaging the connection mechanism between the knob 100 and the lock 500, thereby preventing the knob lock 900 from being used continuously.
As shown in fig. 3A to 3C-1, the elastic member 340 is a spring plate having a free end 344 abutting against the inner sidewall 220 of the driving barrel 200 and capable of being snapped into the driving recess 240. The free end 344 preferably has a slope 345 for the elastic member 340 to move into and out of the driving recess 240 more smoothly. However, in different embodiments, the elastic member 340 can be configured differently based on manufacturing, design or usage requirements. In the embodiment shown in fig. 4A and 4B, the elastic element 340 is a ball device, which includes a cavity 341, an elastic body 342, and a ball 343. The cavity 341 is disposed on the outer side of the rotating member 300, and the cavity 341 has a top opening 341a and a bottom 341 b. The elastic body 342 is provided on the bottom 341 b. The balls 343 are disposed between the elastic body 342 and the top opening 341a, and can selectively partially protrude from the top opening 341a into the cavity 341 (as shown in fig. 4A) or retract into the cavity 341 (as shown in fig. 4B).
As shown in fig. 1A, 2A and 2B, the knob lock 900 preferably comprises a housing 700, wherein the driving cylinder 200, the rotary member 300, the connecting cylinder 400 and the first lock core 601 are disposed in the housing 700. The housing 700 has a fitting portion 710, and the knob 100 is fitted in the fitting portion 710. The knob 100 preferably has a display opening 180 exposing the nesting portion 710. As shown in the embodiment of fig. 5, when the knob 100 rotates the lock 500 to the unlocking position 582, the opening 180 is shown to expose the unlocking indication area 711 of the engaging portion 710. Therefore, the user can confirm the position of the locking member 500 conveniently, and the convenience of the use of the knob lock 900 is improved.
As shown in fig. 2A, the connecting cylinder 400 preferably has a second lock core 602 connected to the locking element 500, and the locking element 500 can rotate together with the second lock core 602 about the first axial direction 801 as an axis. When the second lock core 602 is in the locked state, the rotation of the lock 500 is restricted by the second lock core 602; when the second lock core 602 is in the unlocked state, the second lock core 602 can drive the lock 500 to rotate. The second cylinder 602 is preferably a key cylinder, and more preferably a customs lock cylinder, customs law enforcement officers, etc. can use a key insertion provided by the manufacturer to unlock and turn the second cylinder 602.
