Example 1

The present embodiment provides a security door, as shown in fig. 1 to 8, including: the door lock comprises a door lock body and a door body provided with the door lock body. Wherein, the lock includes: lock box, telex mechanism and two-way separation and reunion structure. Wherein, a linked switch dial wheel 2 is arranged in the lock box; the electric transmission mechanism is provided with an electric transmission driver and an electric transmission dial wheel 32, and the electric transmission driver drives the electric transmission dial wheel 32 to rotate; the bi-directional clutch structure is connected between the gang switch wheel 2 and the electric wheel 32. For example, the electric drive is a motor, and the motor is connected with the electric dial wheel 32 through a transmission gear 31 group for transmission.

As shown in fig. 2 and 4, the above-mentioned bidirectional clutch structure for a door lock includes: a linkage 14, a drive wheel 11, a connecting wheel 15, an electric clutch 12 and a rotating clutch 13. Wherein, the driving thumb wheel 11 is arranged opposite to the electric thumb wheel 32, and the driving thumb wheel 11 and the connecting thumb wheel 15 are connected between the electric thumb wheel 32 and the linked switch thumb wheel 2; the electric transmission clutch piece 12 and the rotating clutch piece 13 are detachably inserted with each other, the electric transmission clutch piece 12 is arranged in the electric transmission thumb wheel 32 in a sliding manner, and the rotating clutch piece 13 is arranged in the driving thumb wheel 11 in a sliding manner; the linkage 14 is connected between the clutch member and the external drive member.

In the door lock provided in the present embodiment, the clutch member has a clutch state in which the electric clutch member 12 and the rotating clutch member 13 are completely separated from each other by the urging of the external transmission member and the link member 14; when the linkage switch thumb wheel 2 is in a clutch state, the external transmission part drives the driving thumb wheel 11 or the connecting thumb wheel 15 to rotate, so that the driven linkage switch thumb wheel 2 is in a rotating opening and closing state.

In this embodiment, the electric dial wheel 32 has a through hole 321 adapted to pass through the linkage member 14, and the external transmission member pushes the linkage member 14 to be slidably disposed in the through hole 321.

In this embodiment, the electric thumb wheel 32, the connecting thumb wheel 15, the driving thumb wheel 11 and the linked switch thumb wheel 2 can be gears; specifically, the electric thumb wheel 32 is arranged between the driving thumb wheel 11 and the connecting thumb wheel 15, and two linkage switch thumb wheels 2 which coaxially rotate are arranged corresponding to the driving thumb wheel 11 and the connecting thumb wheel 15; the electric transmission thumb wheel 32, the driving thumb wheel 11 and the connecting thumb wheel 15 are coaxially arranged, the two linked switch thumb wheels 2 and the transmission gear 31 meshed with the electric transmission thumb wheel 32 in the gear set of the electric transmission mechanism are coaxially arranged, but the two linked switch thumb wheels 2 and the transmission gear 31 can mutually and separately rotate. The arrangement mode can greatly save the installation space, thereby reducing the installation volume.

Further, as shown in fig. 2, specifically, the inside of the electric clutch member 12 has a guide groove, and the outside of the rotating clutch member 13 has a guide projection slidably provided along the guide groove. The four guide grooves ensure the stability of relative sliding of the two clutch pieces in the sliding process. The more the guide grooves and the guide protrusions are arranged, the higher the guide stability is; in addition, the electric transmission clutch part 12 and the electric transmission dial wheel 32 are also inserted into each other through the slotted holes, so that the stability of rotation between the electric transmission clutch part 12 and the electric transmission dial wheel 32 is ensured, and the rotation clutch part 13 and the driving dial wheel 11 are also inserted into each other through the slotted holes, so that the stability of rotation between the rotation clutch part 13 and the driving dial wheel 11 is ensured.

As shown in fig. 2 and 3, the link 14 in the present embodiment is provided with two link members 14 arranged oppositely, and each link member 14 has a connecting portion 141 and a connecting flange 144. Wherein, the connecting flange 144 is protruded outward along the radial direction of the end of the connecting portion 141; the connecting portion 141 is slidably disposed through the clutch member, and the connecting portion 141 is a cylindrical rod structure in this embodiment, and the two flanges are disposed opposite to each other.

In this embodiment, the link 14 further includes an abutting portion 142 and a pushing portion 143. The pushing part 143 is pushed by the external transmission part and abuts against the clutch parts, so that the pushing part 143 moves one clutch part to move away from the other clutch part; the pushing portion 143 is a face where the two connecting flanges 144 are oppositely disposed.

As shown in fig. 3, the connecting portion 141 slides the link 14 provided in the electric clutch member 12, and the right side of the flange is a pushing portion 143 and the left side of the flange is an abutment portion 142. The two link members 14 are disposed opposite to each other, so that the pushing portions 143 abut against each other to transmit the pushing force, thereby further improving the stability of pushing. The two linkage pieces 14 are oppositely arranged as the pushing conduction of the external transmission piece 14, so that the pushing parts 143 are mutually abutted to realize the conduction of the pushing force, and the pushing stability is further improved. The external transmission member pushes one end of the connecting portion 141 of the linkage member 14, and the abutting portion 142 pushes one clutch member to move, so that the two clutch members are in a relatively separated clutch state, and the stability of the opening and closing action of the door lock is ensured by the arrangement of the linkage member 14. Meanwhile, the distance that the external transmission part at least pushes the linkage part 14 can be set according to the preset clutch distance of the two clutch parts, and the opening and closing accuracy of the door lock is further improved.

As shown in fig. 2 and 3, the door lock of the present embodiment further includes a pair of biasing members 16, the biasing members 16 are disposed on the connecting portion 141 of the linking member 14; the right-hand biasing member 16 has one end abutting against the rotating clutch member 13 and the other end abutting against the driving wheel 11; the left biasing member 16 abuts the electric clutch member 12 at one end and the electric thumbwheel 32 at the other end. Specifically, the biasing member 16 is a spring. In the clutched state, the biasing member 16 has a biasing force that urges either clutch member to return to engagement with one another. For example, as shown in FIG. 5, sliding rotating clutch member 13 to the right disengages electric clutch member 12, and the right biasing member 16 will have a biasing force that urges rotating clutch member 13 to the left; accordingly, as shown in FIG. 6, as the electric clutch member 12 slides to the left and disengages from the electric clutch member 12, the left biasing member 16 will have a biasing force urging the electric clutch member 12 to reset to the right. The arrangement of the biasing member 16 provides a driving force for resetting the clutch member to effect resetting of the clutch member under the biasing force, and also provides for resetting of the linkage member 14 by resetting of the clutch member to facilitate subsequent operation.

The door lock provided in the present embodiment is used and operated as follows:

in the electric driving stage, as shown in fig. 4, in a state that the electric dial wheel 32 and the rotating dial wheel are inserted into each other to rotate synchronously, when the motor receives a driving unlocking signal, the transmission gear 31 rotates to further drive the electric dial wheel 32 to rotate, the electric clutch member 12 in the electric dial wheel 32 and the rotating clutch member 13 inserted into the electric clutch member 12 rotate synchronously, and then the rotating clutch member 13 transmits the rotation to the rotating dial wheel to further rotate through the linked switch dial wheel 2 engaged with the rotating dial wheel for transmission, so as to realize unlocking or locking;

when the motor part has a problem, there are two situations, in the first situation, as shown in fig. 5, if the user is on the left side shown in fig. 5, namely the outer side of the door, the external transmission part is the key 41, the lock core extends into the lock core through the key 41 and is mutually abutted and pushed with the linkage part 14 on the left side, because the pushing parts 143 of the two linkage parts 14 are mutually abutted, the abutting part 142 of the right linkage part 14 pushes the rotating clutch part 13 to move rightwards until the rotating clutch part 13 and the electric clutch part 12 are in a completely separated clutch state; then, when the key 41 is rotated, the key 41 is in a second driving state to drive the connecting dial wheel 15 to rotate, and correspondingly, the linked switch is driven by the connecting dial wheel 15 to realize an opening and closing state of the door lock.

In the second case, if the user is at the right side shown in fig. 6, i.e. at the side inside the door, the external transmission member is a square iron sheet 42, the square iron sheet 42 extends into the square groove at the right side of the driving thumb wheel 11, and abuts against the linkage member 14 at the right side and pushes the linkage member 14 to move to the left side, and due to the abutting of the pushing portions 143 of the two linkage members 14, the abutting portion 142 of the linkage member 14 at the left side pushes the electric clutch member 12 to move to the left until the rotating clutch member 13 and the electric clutch member 12 are in a completely separated clutch state; thereafter, when the square iron sheet 42 rotates, the square iron sheet 42 is in a first driving state for driving the driving dial wheel 11 to rotate, and correspondingly, the linked switch is driven by the connecting dial wheel 15 to realize an opening and closing state of the door lock.

According to the bidirectional clutch structure for the door lock, due to the fact that the electric transmission clutch part 12 is linked with the electric transmission dial wheel 32, the realization of multiple output of opening and closing of the door lock is achieved; the rotary clutch piece 13 is linked with the driving thumb wheel 11, and the electric transmission clutch piece 12 and the rotary clutch piece 13 have two conditions, wherein in one condition, the electric transmission clutch piece and the rotary clutch piece are mutually inserted, the electric transmission thumb wheel 32 can rotate to drive the driving thumb wheel 11 to rotate, and then the linkage switch thumb wheel 2 in the lock box is driven to rotate to realize electric opening and closing of the door lock; in another case, that is, when the motor cannot drive the linked switch gear to rotate, because the driving thumb wheel 11 and the electric thumb wheel 32 are in the clutch state of being separated from each other at two clutch members under the clutch state, so that the influence of locking of the electric thumb wheel 32 is not received, the external transmission member directly controls the linked switch thumb wheel 2 to rotate to realize manual opening and closing of the door lock. The problem that the electric door lock cannot be opened due to the fact that the motor is locked is solved, and the adaptability of the door lock is improved; in addition, the external transmission parts can be pushed to separate from each other in multiple directions, so that the stretching of the external transmission parts along multiple directions of the clutch structure when the door lock is opened is improved, and the adaptability of subsequent door lock installation is improved.

Example 2

The security door provided in this embodiment is different from the security door provided in embodiment 1 in that: the driving thumb wheel 11 and the connecting thumb wheel 15 are arranged on the same side of the electric thumb wheel 32, so long as the rotation of the driving thumb wheel 11 and the connecting thumb wheel 15 can be realized when an external transmission part extends in.

Furthermore, the connecting thumb wheel 15 may not be provided, and the external transmission members on both sides may be directly connected to the driving thumb wheel 11 after the clutch member is in the clutch state. For example, after two clutch pieces are completely separated, the external transmission pieces are positioned at two sides of the bidirectional clutch structure and are mutually limited with the driving thumb wheel 11, so that when the external transmission pieces rotate, the linkage switch thumb wheel 2 is driven to rotate to drive the door lock to open and close.

Example 3

The security door provided in this embodiment is different from the security door provided in embodiment 1 or 2 in that: in this embodiment, one linkage member 14 may be further provided, the linkage member 14 is a cylindrical rod inserted into the through hole 321, and has a connection flange 144 installed on the connection portion 141, both sides of the flange are abutting portions 142, and the abutting portions abut on the mutually facing wall surfaces of the electric clutch member 12 and the rotating clutch member 13, respectively, so that driving can be realized as well. As a further variant of this embodiment, the door lock may be provided without the linkage 14, just by actuation of an external transmission member to effect disengagement of the two clutch members.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
