Description

Knob-type lock core transmission structure that locks automatically after damage

The present invention provides a transmission structure of a knob-type lock core that is automatically locked after being damaged, especially a lock core that is automatically locked at one end of the lock body after being damaged, so that the damaged end cannot be unlocked, and the knob at the other end is still locked. Can be unlocked and unlocked.

By the way, the commonly used locks usually use the upper and lower beads in the lock core to achieve the effect of locking and anti-theft; When the upper and lower beads are in the unlocked position, the lock can be opened by turning the cam; however, if the arrangement of the upper and lower beads in the lock seat and the lock core is too complicated, it is difficult to move the upper and lower beads to the unlocked position. Destroy the lock seat directly from the outside to break the joint between the lock seat and the lock core, take out the lock core, and then turn the cam directly to unlock. This method can still unlock the lock within a few minutes, so no matter what the complexity of the lock Mind, if the intensity of breaking the lock is greater than the rigidity of the lock seat, the lock seat can be destroyed and the lock core can be taken out. Therefore, its anti-theft performance is still insufficient.

However, it is known to provide a "lock mechanism" such as the Chinese mainland invention patent publication No. 105649408 A, which is mainly due to the first clutch sub-assembly being provided with a compression spring and a first clutch member. The first clutch member includes Stepped shaft, the stepped shaft has a driving member, and the first clutch member includes a cylindrical toughened steel plug installed in its axial opening, in addition, the first clutch member includes a diameter To the moving lock pin, it is radially outwardly biased by the compression spring; and the second clutch assembly includes a second clutch member, which contains a stepped shaft and has a radially protruding drive member; the second clutch assembly into a push pin, which is mounted axially against the larger diameter portion of the second clutch member; whereby, when the second lock cylinder alone or with the second lock actuator housing is removed, its The push pin and the second clutch member will fall, so that the compression spring pushes the first clutch member, and then the lock pin is pressed by the spring and stretches out to fit the lock pin hole on the first lock cylinder to lock the clutch; The lock pin will also protrude through the lock pin hole to fit the lock pin hole on the camshaft; so that the cam is restricted by the first lock cylinder, so that the outside intruder cannot turn the cam to unlock, and the inside personnel It can still be unlocked by driving the first lock actuator.

But this, because the person who is located in the room needs to unlock the lock, mainly by pushing the finger to combine with the key assembly, and then turn and unlock the lock instead of unlocking the lock pin. When the second lock cylinder and the housing of the second lock actuator are removed as a whole, there is a possibility of directly destroying and turning the first clutch member through a tool to unlock.

As far as the usual usage is concerned, the knob 3 can be arranged on a In the room where anti-theft is desired, one end of the lock core 2 is arranged at the opposite outdoor place; and in one embodiment, the lock core 2 can be rotated only through the correct key, and its setting is conventional Known technology, so do not go into details here, and the setting form of lock core 2 is only for illustration, not as limitation; This lock core 2 is provided with a transmission block 21 toward this cam 4 end transmission, and this transmission block 21. An elastic unit 22 is provided at one end opposite to the cam 4. When the transmission block 21 is in an unlocked position, it is correspondingly assembled and transmitted to the cam 4;

The lock body 1 is provided with a sleeve 5 at one end of the knob 3, and the sleeve 5 is correspondingly driven on the cam 4, and the knob 3 is provided with a lock rod 31, which is axially movably sleeved on the sleeve. In the cylinder 5, it is transmitted in the sleeve 5 in the direction of rotation, and the locking lever 31 is provided with an elastic element 32, a locking element 33 and a driver 34 in sequence towards the end of the cam 4, and the locking element 33 has An abutting portion 331, and a receiving portion 332 protrudes radially from the end of the abutting portion 331; the cam 4 is provided with a through groove 41 corresponding to the driver 34 and the transmission block 21;

A seat body 6 is assembled on one end of the lock body 1, and the seat body 6 is correspondingly sleeved on the sleeve 5, and the seat body 6 is provided with at least one stop component in the radial direction of the sleeve 5 7, and the sleeve 5 is provided with a receiving hole 53 corresponding to the stop assembly 7; the stop assembly 7 includes an elastic body 71, a stop block 72 and a receiving block 73, and the receiving block 73 is correspondingly accommodated in the receiving hole 53, and is correspondingly received by the locking element 33, while the elastic body 71 and the stopper 72 are correspondingly arranged in the seat body 6, specifically, the seat body 6 can be provided with There is an accommodating groove 61 for correspondingly accommodating the elastic body 71 and the stop block 72; the elastic body 71 elastically abuts against the stop block 72 and the receiving block 73 in the direction of the locking element 33, and In an initial position, as shown in Figure 3, the abutment of the stop block 72 and the receiving block 73 corresponds to the connection between the seat body 6 and the sleeve 5 in the radial direction, so The lock can be unlocked by rotating the knob 3, and then sequentially driving the sleeve 5 and the cam 4 through the lock rod 31; guide surface 311;

Thereby, in the initial position, as shown in Fig. 3 and Fig. 5, the driver 34 and the transmission block 21 are directly or indirectly abutted against each other in the through groove 41, and the receiving block 73 Corresponding elastic abutment against the outer edge of the receiving portion 332; As far as the abutment between the driver 34 and the transmission block 21 is concerned, it can be configured as described in this embodiment, the two are directly connected to each other in the through groove 41 In other embodiments, the drive 34 and the drive block 21 can be indirectly butted against each other according to the requirements of use or the configuration requirements of the length of the drive 34 in the axial direction, but it is only an example Description, not as a limitation; and as mentioned above, one end of the knob 3 is configured, which can be unlocked by rotating the knob 3 through the lock rod 31 sequentially driving the sleeve 5 and the cam 4, and the lock core is configured 2, as known technology, after inserting the correct key in the lock core 2, the key can directly or indirectly push the transmission block 21 to the unlocked position as shown in Figure 5, so that the transmission block 21 can The transmission group is on the cam 4, and then when the lock core 2 is rotated, it can be driven on the cam 4 through the transmission block 21 to unlock, and its specific configuration can be as the configuration of the known technology, and in a preferred embodiment, It can also be set up as in the present invention, and its description will be described in detail later.

As shown in Figures 6 and 7, when the transmission block 21 is not pushed against by the elastic unit 22, such as when the lock core 2 is taken out due to being directly damaged by an external force, the transmission block 21 is driven by the lock core 2. Therefore, the transmission block 21 at the damaged end will not be supported by the elastic unit 22 because the lock core 2 is taken out. At this time, the elastic element 32 will elastically push the locking element 33 and the driver 34, so that Push the transmission block 21 away from the unlocking position, so that the transmission block 21 cannot be connected with the cam 4 in transmission and assembly. At the same time, because the locking element 33 is pushed by the elastic element 32, the receiving portion 332 will not be aligned radially and Accept the receiving block 73, so that the receiving block 73 is elastically pushed by the elastic body 71 and abuts against the abutting portion 331, and is positioned between the receiving portion 332 and the locking bar 31, so that the latching element 33 cannot be pushed back by the damaged end, and the stop block 72 will be located at the junction of the seat body 6 and the sleeve 5 in the radial direction, therefore, it is blocked by the stop block 72, so it is blocked The damaged end will not be able to rotate the cam 4 to unlock, and in this case, even if the knob 3 is rotated directly or indirectly, the stop block 72 will still be stuck at the joint between the seat body 6 and the sleeve 5 in the radial direction Therefore, it can achieve the purpose of automatic locking after destruction, and then achieve the effect of excellent anti-theft performance.

It should be noted that the receiving hole 53 of the sleeve 5 is not completely aligned with the accommodating groove 61 of the seat body 6 due to the possible transmission of the knob 3 , so that the stopper 72 is resisted by the elastic body 71 at this time. Push against the outer surface of the sleeve 5 instead of the receiving hole 53, which will make the automatic locking function invalid, and when it is not locked, as mentioned above, the knob 3 can be rotated corresponding to the rotation of the cam 4. Therefore, in a preferred embodiment, a plurality of receiving holes 53 can be radially arranged in the sleeve 5, and each receiving hole 53 is correspondingly accommodated a receiving block 73, so that the thief can destroy the When the lock core 2 tries to rotate the cam 4, once the receiving hole 53 is aligned with the accommodating groove 61, the automatic locking mechanism can be activated as described above, so that the cam 4 is stuck against the seat 6 and the seat body 6 by the stopper 72. The joint of the sleeve 5 in the radial direction can no longer be rotated, so as to achieve a comprehensive anti-theft mechanism.

And if it is necessary to operate the knob 3 to unlock, as shown in Figure 8, one end of the knob 3 (such as: indoor) must be pushed through the knob 3 in the axial direction, so that the guide surface 311 of the lock rod 31 is pushed radially. The receiving block 73, so that the abutment of the stop block 72 and the receiving block 73 is corresponding to the connection between the seat body 6 and the sleeve 5 in the radial direction, at this time, the knob 3 can be rotated And unlock; And what can be known is that when pushing the knob 3 in the axial direction, the guide surface 311 of the lock rod 31 can radially push the receiving block 73, so the guide surface 311 can be a corresponding slope, or on the receiving block. 73 configures the corresponding guide surface to achieve its purpose and effect, but it is only an example and not a limitation.

As far as the transmission connection between the locking rod 31 and the sleeve 5 is concerned, the sleeve 5 is further equipped with a limit groove 51, which is arranged in the axial direction, and the locking rod 31 is provided with a position corresponding to the The guide part 312 of the limit groove 51, by this, because the sleeve 5 is pivotally connected to the seat body 6, it can only rotate in the direction of rotation, but cannot be displaced in the seat body 6 in the axial direction, and through the limiter The setting of the bit groove 51 and the guide part 312 will enable the locking rod 31 to be axially displaced in the sleeve 5, and then the knob 3 can be axially pushed as mentioned above, thereby reaching the unlocked position. In addition, It can also be transmitted to the sleeve 5 in the rotation direction, so as to be transmitted to the cam 4 through the rotation of the sleeve 5 to unlock.

As far as the configuration of the elastic body 71 and the locking element 33 is concerned, in a specific embodiment, a connecting groove 313 can be recessed in the radial direction of the locking rod 31, and the elastic body 71 is fixed in the connecting groove 313. The abutting portion 331 is elastically abutted, so that the elastic body 71 will not lose its function of elastic abutment due to stress and distortion, so as to ensure the stability of the overall transmission of the present invention.

In addition, in terms of the transmission mode of the sleeve 5 to the cam 4, it can be directly connected to the transmission. In this embodiment, a driving block 52 is provided for the corresponding transmission between the sleeve 5 and the cam 4. And the sleeve 5 is correspondingly driven to the cam 4 by the driving block 52, so as to reduce the complexity of its parts and facilitate the manufacture and configuration of each component, but it is only for illustration, not as a limited.

In order to further enhance the anti-theft of the present invention as a whole, in order to prevent the intruder from driving, knocking or destroying the cam 4 by the destroyed end when the locked position is in the locked position, it is better to use A limiter 341 can be further provided on the side edge of the actuator 34; the through groove 41 is radially arranged with a limiter 42 corresponding to the limiter 341, and the limiter 341 and its corresponding limiter Between 42, they are elastically assembled when they are aligned with each other; at the initial position, as shown in Figures 3 to 5, the limiting unit 42 is not aligned with the limiting member 341; and When in the locked position, as shown in Figures 6 and 7, the actuator 34 will be pushed away by the elastic element 32 to push the transmission block 21 away, so that the limiting member 341 and the limiting unit 42 can be mutually aligned and assembled.

In order to improve the stability of positioning between the limiting member 341 and the limiting unit 42, the limiting member 341 is a slightly rectangular cutout, and the limiting unit 42 includes a block 421 and at least An elastic member 422, the block 421 is arranged in a shape corresponding to the stopper 341, so that the block 421 can be assembled with the stopper 341 in a large area, so as to prevent the transmission The device 34 is knocked by force to cause the block 421 to pop out the stopper 341 and cause its automatic locking function to fail; and the elastic member 422 is arranged and abutted against the inner wall of the through groove 41, and is elastically abutted For the corresponding block 421, as shown in Figures 3 and 4, when it is in the initial position, since the limiting member 341 has not yet aligned with the limiting unit 42, the locking block 421 will be elastically resisted by the elastic member 422. Push against the side edge of the actuator 34, the transmission block 21 or the sliding block provided during the period, and when it is in the locked position, as shown in Figures 6 and 7, the clamping block 421 will be positioned against the limiting member 341 , so that the clamping block 421 is elastically assembled on the corresponding limiting member 341, and in order to reduce the elastic member 422 is not easy to be compressed by the spring of the clamping block 421 when knocked by an external force, so a plurality of elastic members 422 can be provided , to increase its coefficient of elasticity to reduce the possibility of elastic compression. In addition, in order to prevent the elastic part 422 from being skewed by knocking, the block 421 is provided with a corresponding assembly part for assembling the elastic part 422 4211, in a specific embodiment, the assembly part 4211 can be a concave hole corresponding to the elastic part 422, so as to correspondingly assemble the elastic part 422, so that the elastic part 422 is not easy to disengage and be skewed so that the assembly of the limiting part 341 Connection fails.

Therefore, when in the unlocked position as mentioned above, because the transmission device 34 and the cam 4 are locked in the axial direction by the limiting member 341 and the limiting unit 42, the cam 4 and the knob 3 can still be locked. Synchronous transmission in the direction of rotation, so when the knob 3 is rotated, the cam 4 can still be unlocked through the transmission of the actuator 34, so that the user at one end of the knob 3 will not be locked because the other end is damaged.

In addition, as far as the arrangement of the block 421 and the elastic member 422 is concerned, a set of joint holes 43 can be pierced on the cam 4 corresponding to the position of the limiting unit 42, and the elastic member 422 and at least part of the The clamping block 421 is arranged in the group connecting hole 43. Preferably, in order to facilitate assembly, the group connecting hole 43 is provided through, so that at least one end is provided with the cam 4, and the group connecting hole 43 is fixed with a positioning element 431 at one end opposite to the clamping block 421, and the elastic member 422 is elastically resisted between the positioning element 431 and the clamping block 421; and in one embodiment, since the cam 4 There is a locking protrusion 44 for locking the door body, so the setting of the connecting hole 43 needs to avoid the locking protrusion 44. In addition, in order to facilitate the configuration of the shape of the actuator 34, the position limiting Part 341 can be inclined and cut to form the aforementioned slightly rectangular slit, so that the overall shape of the driver 34 is simple, and the effect of automatic locking after the transmission and destruction can be achieved without complicated design.

In addition, regarding the configuration of the lock body 1 for the lock core 2 and the knob 3, in one embodiment, the two side ends of the lock body 1 are respectively provided with a connecting rod 11, and the connecting rod 11 is at one end of the corresponding lock core 2. It is connected with a bushing 12, and the lock core 2 is set in the cover, and the other end is set with the seat body 6; the connecting rod 11 can be used for an intruder to remove the lock core 2 and the lock core 2 by knocking. When the bushing 12 is used, it is easy to be broken by the connecting rod 11, so that the lock body 1 is not broken at the part not connected to the connecting rod 11 and there is a doubt that the automatic locking will be lost. Therefore, in one embodiment, the connecting rod 11 can be provided with a ring groove 111, to weaken its structural rigidity, to be more conducive to being knocked by force and broken by the ring groove 111, so that it is difficult to directly damage the lock body 1.

As for the specific configuration of the lock core 2 and the transmission block 21, in one embodiment, the lock core 2 is at one end corresponding to the cam 4, and a transmission wheel 23 is set for transmission in the direction of rotation, and the inner axis of the transmission wheel 23 A transmission groove 231 is pierced, and the transmission block 21 is arranged in the transmission groove 231; the transmission block 21 protrudes in the radial direction with a projection 211 corresponding to the transmission groove 231; the through groove 41 is in the The radial direction is provided with slide grooves 411 respectively corresponding to the projections 211, and the slide grooves 411 are configured so that the projections 211 can be displaced in the axial direction, and can drive the rotation of the cam 4 in the rotation direction By.

In one embodiment, when the lock core 2 is destroyed, the drive block 21 cannot be removed from the cam 4, and is covered by the drive 34 at the other end, so that it cannot be destroyed by knocking again. Preferably, the transmission wheel 23 can be configured to be idling and positioned on the cam 4. As shown in FIG. A stopper part 232 corresponding to the fastening groove 212 is respectively provided, and it passes through an elastic member 233 to abut against the wall surface of the transmission block 21, so that in the locked position, the stopper part 232 can correspond to Assembled in the fixing groove 212, the transmission block 21 and the transmission wheel 23 are fixed to each other, so that the transmission block 21 cannot be displaced axially, so the transmission block 21 cannot be removed, and the shielding effect as described above can be achieved , and as the aforementioned, because under the locked position, the transmission block 21 has been pushed away from the chute 411, therefore, its transmission block 21 and the transmission wheel 23 can only idle on the cam 4, and cannot drive the cam 4 at all.
