Specifically, the transmission 10 includes a mounting seat, an unlocking mechanism 2, a linkage 102, and a locking member 3. The mounting seat provides a mounting carrier for the unlocking mechanism 2, the linkage 102 and the locking member 3. The unlocking mechanism 2 is matched with a lock body of the door lock, and the lock opening and closing function is realized through movement. The interlocking member 102 is in interlocking fit with the handle 7 of the door lock (specifically, interlocking fit can be achieved through the connecting hole 1024 shown in fig. 1), and is in interlocking fit with the unlocking mechanism 2, so that the driving force of the handle 7 is transmitted to the unlocking mechanism 2, the unlocking mechanism 2 is driven to move, and the unlocking and locking functions are achieved. The locking member 3 is provided on the mounting seat and can be mounted in either a locked position or an unlocked position.

Specifically, when the locking member 3 is mounted in the locking position, the unlocking mechanism 2 or the interlocking member 102 can be locked or both the unlocking mechanism 2 and the interlocking member 102 can be locked, so that the unlocking mechanism 2 cannot move freely. Therefore, a lawbreaker can penetrate a special tool through the cat eye, and the unlocking mechanism 2 cannot act no matter how the handle 7 is operated, so that the door lock cannot be opened to implement lawbreak, and the safety of the door lock is improved. When the locking piece 3 is installed at the unlocking position, the locking of the unlocking mechanism 2 or the linkage piece 102 or the unlocking mechanism 2 and the linkage piece 102 is released, the unlocking mechanism 2 can move freely, and the user can normally open the door lock by rotating the handle 7.

Meanwhile, compared with the scheme that two limiting bulges are matched with one limiting groove 114, the hollow limiting groove 114 is not easy to interfere with other structures, so that the product structure is simplified, and the use reliability of the product is improved.

Of course, the number of the limiting protrusions and the limiting grooves 114 can be two.

Specifically, the limiting protrusion is a limiting ball 4, as shown in fig. 1, the locking member 3 is provided with a guide hole 31, as shown in fig. 1 and 7, the limiting ball 4 is installed in the guide hole 31 and is adapted to move relative to the guide hole 31; an elastic member is further disposed in the guide hole 31, as shown in fig. 1 and 7, and the limit ball 4 is sandwiched between the elastic member and the mounting seat, as shown in fig. 7.

Example two

The difference from the first embodiment is that: on the basis of the first embodiment, further, the linkage 102 is configured to: the unlocking mechanism 2 is driven to be locked under the condition of moving to the locking position, and the unlocking mechanism 2 is driven to be unlocked under the conditions of moving from the locking position to the first unlocking position in a forward direction and moving from the locking position to the second unlocking position in a reverse direction.

The transmission 10 further includes: a first reversing member 104 (shown in fig. 1 and 2). The first reversing element 104 is matched with the linkage element 102, and is configured to be suitable for being installed at different positions, and is used for switching the motion area of the linkage element 102, so that the linkage element 102 reciprocates between the first unlocking position and the locking position or reciprocates between the second unlocking position and the locking position, and the use mode of the handle 7 is switched.

This scheme is through addding first switching-over piece 104 for can switch with the motion region of handle 7 interlock complex interlock piece 102, can switch handle 7's user mode from this, thereby changed the single user mode of lock handle 7 among the prior art, be favorable to satisfying different users' use habit, enlarged the applicable crowd of product, improved the commonality of product, be favorable to the marketing of product.

Specifically, the linkage member 102 can reciprocate between a first unlocking position, a locking position, and a second unlocking position, and the first unlocking position and the second unlocking position are located on two sides of the locking position, so that the linkage member 102 starts from the same locking position and can move to the first unlocking position and the second unlocking position in opposite directions, and then a region between the locking position and the first unlocking position can be recorded as a first movement region, and a region between the locking position and the second unlocking position can be recorded as a second movement region.

Recording the moving direction of the linkage member 102 from the locking position to the first unlocking position as a forward direction, when the linkage member 102 moves in the first movement area, the forward movement realizes unlocking, and the reverse movement realizes locking; when the linkage member 102 moves in the second motion area, the reverse motion realizes unlocking, and the forward motion realizes locking. Since the interlocking member 102 is interlocked with the handle 7, the moving direction of the interlocking member 102 corresponds to the moving direction of the handle 7, and therefore, when the moving direction of the interlocking member 102 changes, the moving direction of the handle 7 also changes correspondingly. Since the first direction-changing member 104 has a plurality of mounting positions, when the first direction-changing member is mounted at different positions, the linkage member 102 can be switched between the first motion region and the second motion region, so that the motion direction of the linkage member 102 during unlocking and locking can be changed, and the use mode of the handle 7 can be switched.

Such as: when the handle 7 is pushed, the linkage piece 102 is driven to move forward (downward in the figure), when the handle 7 is pulled, the linkage piece 102 is driven to move reversely (upward in the figure), and when the linkage piece 102 moves in the first motion area, the handle 7 is pushed to unlock, and the handle 7 is pulled to lock; when the linkage 102 moves in the second motion area, the handle 7 is pulled to unlock, and the handle 7 is pushed to lock. Therefore, by changing the installation position of the first reversing member 104, the use mode of the handle 7 can be switched, and the use habits of different users can be further met.

When the linking member 102 is located at the locking position, the two first mounting portions correspond to two ends of the limiting sliding groove 111 one by one, and at this time, the portion of the first reversing member 104 embedded in the limiting sliding groove 111 is just located at the first end or the second end of the limiting sliding groove 111, as shown in fig. 3. When the first reversing piece 104 is just at the first end of the limiting sliding groove 111, the first reversing piece can only move towards the second end, and unlocking is realized; when the first reversing piece 104 is just at the second end of the limiting sliding groove 111, the first reversing piece can only move towards the first end to realize unlocking, and the moving direction is just opposite to that of the first reversing piece. Therefore, by changing the position of the first reversing member 104, the moving direction of the interlocking member 102 when driving the lock to be unlocked can be changed, and the use mode of the handle 7 can be switched.

In any of the above embodiments, the door lock is a sliding door lock.

Of course, the door lock is not limited to the sliding door lock, and may be a door lock that is opened and closed by rotating the handle 7.

The following takes a sliding door lock in the attached drawings as an example, and describes in detail a push-pull mechanism of the intelligent sliding door lock, which specifically comprises: an upper cover fixing screw (namely a screw for fixing the top cover 11), a push-pull box upper cover (namely the top cover 11 of the transmission box 1), a flat iron (namely an unlocking piece 23), a transmission first gear (namely a second rotating piece 22), a flat iron fixing screw (namely a screw for fixing the flat iron), a positioning steel ball (namely a limiting ball 4), a steel ball compression spring 33 (namely an elastic piece), a cat eye prevention sliding block (namely a locking piece 3), and a push-pull box lower cover (namely the bottom cover 12 of the transmission box 1), the key unlocking second gear (namely, the second transmission gear 1084), the key unlocking first gear (namely, the third transmission gear 1086), the key unlocking third gear (namely, the first transmission gear 1082), the key unlocking free piece 1088, the transmission second gear (namely, the first rotating piece 21), the first reversing screw (namely, the first reversing piece 104), the second reversing screw (namely, the second reversing piece 106) and the push-pull sliding block (namely, the linkage piece 102).

The first reversing screw and the push-pull sliding block form a sliding block assembly; the second reversing screw and the transmission second gear form a second gear assembly; the flat iron, the flat iron fixing screw and the transmission first gear of the unlocking mechanism 2 form a first gear assembly; the positioning steel balls, the steel ball compression spring 33 and the cat eye prevention sliding block form a cat eye prevention assembly; the flat iron and the flat iron fixing screw of the key unlocking mechanism 108, the key unlocking second gear, the key unlocking first gear, the key unlocking third gear and the key unlocking free piece 1088 form a key unlocking assembly.

After assembly, the push-pull box assembly (i.e., the transmission device 10) is fixed on the door lock panel 8 (i.e., the panel 8 of the panel assembly); the switch piece 5 can slide left and right in the chute (namely the mounting chute 82) of the door lock panel 8, and the switch piece 5 is linked with the cat eye prevention slide block; the decorative plate 9 is fixed on the door lock panel 8 and synchronously limits the axial movement of the switch piece 5; the door lock handle 7 is fixed to the door lock panel 8.

Wherein, switch 5 is established on the back panel 85 of lock, and switch 5 installs on the panel 8 that the lock is located the door promptly, and the user in the door can open as required like this and prevent the cat eye function or close and prevent the cat eye function. The key unlock mechanism 108 may be mounted on the front panel 86 and/or the rear panel 85.

As shown in fig. 5 to 8, the cat eye prevention sliding block is arranged on the right side of the sliding chute of the lower cover of the push-pull box, the positioning steel ball is fixed in the positioning groove on the right side of the upper cover of the push-pull box by the steel ball compression spring 33, the movement of the cat eye prevention sliding block is limited, the first transmission gear can freely rotate along the central shaft, the flat iron and the flat iron fixing screw of the unlocking mechanism 2 are driven to rotate, the door lock is unlocked, and the cat eye prevention function is in a closed state.

When preventing that cat eye function need open, need toggle switch spare 5 to the motion of cat eye slider is prevented in the linkage, prevents that cat eye slider from moving to the left side of push-and-pull box lower cover spout, as shown in fig. 4. When the cat eye prevention sliding block is arranged on the left side of the sliding groove of the lower cover of the push-pull box, the step surface of the transmission first gear is attached to the outer surface of the cat eye prevention sliding block, the rotation of the transmission first gear is limited, the flat iron and the flat iron fixing screw are limited to rotate, and finally the door lock cannot be opened.

From this, the lock of this application can be used to prevent that the cat eye unblanks in the intelligence lock door, has improved the security of lock greatly.

The transmission mode of the push-pull mechanism is as follows:

the sliding block component slides up and down in a sliding groove (namely a guide sliding groove 121) of the lower cover of the push-pull box to drive a second reversing screw in the second gear component to move, so that the transmission second gear is driven to rotate, the transmission second gear is meshed with the transmission first gear, the transmission first gear rotates along with the transmission second gear, and finally the flat iron of the unlocking mechanism 2 is driven to unlock.

The push-pull mechanism realizes the transmission modes of push-pull, left push, left pull, right push and right pull:

the first reversing screw and the push-pull slide block form a slide block assembly, and when the first reversing screw is fixed at different hole positions (namely two first mounting holes 1021) of the push-pull slide block, the reversing screw and the upper cover (the limiting chute 111) of the push-pull box are limited, so that the push/pull limitation is realized.

The second reversing screw and the transmission second gear form a second gear assembly, and when the second reversing screw is fixed on different hole sites (namely two second mounting holes 212) of the transmission second gear, the rotation directions of the transmission second gear are different when the second reversing screw moves up and down, so that four transmission directions of 'left pushing', 'left pulling', 'right pushing' and 'right pulling' are correspondingly realized.

Specifically, for the sliding door lock in the drawings, by changing the installation positions of the first direction changing member 104 and the second direction changing member 106, the transmission device 10 can have four transmission modes of "left push", "left pull", "right push", and "right pull", so as to achieve unlocking.

The first mode is as follows: the first and second diverting

members

104 and 106 are in the positions shown in fig. 3 to 5, namely: the first diverter 104 is mounted in the upper first mounting hole 1021 and the second diverter 106 is mounted in the right second mounting hole 212. At this time, the handle 7 is pushed, the linkage member 102 slides downward, and drives the first direction changing member 104 and the second direction changing member 106 to move downward, so that the second direction changing member 106 drives the first rotating member 21 to rotate rightward, and further drives the second rotating member 22 and the unlocking member 23 to rotate leftward to unlock. This situation corresponds to the "left push" implementation of the unlocking transmission.

The second mode is as follows: on the basis of the first mode, the position of the second direction-changing member 106 is changed, and the second direction-changing member 106 is installed in the second installation hole 212 close to the left, so that the handle 7 is pushed, the linkage member 102 slides downwards, the first direction-changing member 104 and the second direction-changing member 106 are driven to move downwards, the second direction-changing member 106 drives the first rotating member 21 to rotate leftwards, and the second rotating member 22 and the unlocking member 23 are driven to rotate rightwards to realize unlocking. This situation corresponds to the "push right" implementation of the unlocking transmission.

The third mode is as follows: on the basis of the first mode, the position of the first direction changing member 104 is changed, and the first direction changing member 104 is installed in the first installation hole 1021 below, so that the handle 7 is pulled, the linkage member 102 slides upwards to drive the first direction changing member 104 and the second direction changing member 106 to move upwards, the second direction changing member 106 drives the first rotating member 21 to rotate leftwards, and further drives the second rotating member 22 and the unlocking member 23 to rotate rightwards to realize unlocking. This situation corresponds to the "right pull" implementation of the unlocking transmission.

The fourth mode is that: on the basis of the third mode, the position of the second direction-changing member 106 is changed, and the second direction-changing member 106 is installed in the second installation hole 212 close to the left, so that the handle 7 is pulled, the linkage member 102 slides downwards to drive the first direction-changing member 104 and the second direction-changing member 106 to move downwards, the second direction-changing member 106 drives the first rotating member 21 to rotate rightwards, and further the second rotating member 22 and the unlocking member 23 are driven to rotate leftwards to realize unlocking. This situation corresponds to the unlocking transmission mode realized by "left pulling".

Therefore, the universality of the sliding door lock is greatly improved, the market competitiveness of the product is greatly improved, and the market popularization of the product is facilitated.

Further, the above components may be combined as needed for the front panel 86 (i.e., the panel 8 of the door lock located at the outer portion of the door) and the rear panel 85 (i.e., the panel 8 of the door lock located at the inner portion of the door).

The combination applied to the front panel 86 is as follows, as shown in fig. 10 to 15:

the transmission box 1 on the front panel 86 needs to realize the functions of push-pull transmission unlocking and mechanical key transmission unlocking, and the functions need to be combined by the sliding block assembly, the second gear assembly, the first gear assembly and the key unlocking assembly.

For push-pull transmission unlocking: the handle 7 is pushed and pulled, the handle 7 rotates along the rotating shaft 72 of the handle 7, the swing tongue 71 of the handle 7 rotates along with the handle 7, and the push-pull sliding block in the transmission box 1 is driven to slide up and down, so that transmission unlocking is realized.

Unlocking for mechanical key drive: after the mechanical key unlocks the mechanical lock cylinder 83, the mechanical lock cylinder rotating shaft 84 is driven to rotate, so that the key is driven to unlock the third gear to rotate, and the mechanical key is unlocked.

The combination applied to the rear panel 85 is as follows, as shown in fig. 16 to 21:

the transmission box 1 on the rear panel 85 needs to realize push-pull transmission unlocking and prevent the cat eye function (prevent that the tool for outdoor use from passing through the cat eye and pushing the door inner handle 7), and the function needs the slider assembly, the second gear assembly, the first gear assembly and the cat eye prevention assembly to be combined for use.

For push-pull transmission unlocking: the push-pull handle 7 rotates along the rotating shaft 72 of the handle 7, the swing tongue 71 of the handle 7 rotates along with the handle 7, and the push-pull sliding block in the transmission box 1 is driven to slide up and down, so that transmission unlocking is realized.

For the cat-eye prevention function: the anti-peep hole switch is shifted left and right to drive the anti-peep hole sliding block to slide left and right, so that the anti-peep hole function is switched on and off.

In addition, sliding door lock drive mechanism assembles on 8 bases of lock panel with spare part form mostly on the intelligent lock market, influences the whole line of product, and is difficult to realize the standardization of follow-up design. The transmission box 1 integrates a push-pull transmission mechanism in an assembly mode, so that subsequent design standardization is facilitated, and transmission use of the front panel 85 and the rear panel 85 is realized through combination of different parts.
