Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the present disclosure, unless otherwise stated, the terms of orientation such as "inner" and "outer" are generally used with respect to the self-outline of the corresponding components, for example, the inner side of the panel 3 refers to the side of the door lock where the latch tongue is provided, and the outer side refers to the side where various operating components are provided, such as the back lock knob or the door handle.

As shown in fig. 1 and 2, the present disclosure provides an anti-lock mechanism for a door, comprising a panel 3 and a knob 1 connected to the panel 3 and capable of moving perpendicular to the panel surface, wherein the knob 1 has a pressed-in position close to the panel 3 and a released position far from the panel 3, and the knob 1 drives a latch (not shown in the figure) in the panel 3 to rotate at the pressed-in position so as to anti-lock or unlock the door. Here, the proximity and the distance of the knob 1 to and from the faceplate 3 are relative, and the knob 1 in the pressed-in position is closer to the outer plate surface of the faceplate 3 than to the released position. Through the technical scheme, when a user locks reversely, the user can rotate to drive the bolt in the panel 3 by pressing the knob 1 towards the direction close to the panel 3. The operation mode of firstly pressing in and then rotating disassembles the back lock of the door into two steps, so that the problem of misoperation in the related technology can be avoided, for example, the problem that the door is locked by carelessly triggering the knob 1 by children or pets, and the user cannot open the door from the outside can be avoided, and the safety of the back lock mechanism is improved.

Normally, a certain gap is required between the knob 1 and the faceplate 3, so that a space is left for pressing the knob 1. The push-in position of the present disclosure means that the knob 1 is pushed to move toward the panel 3, and in the push-in position, the knob 1 can rotate and drive the bolt to rotate through the transmission assembly. The transmission assembly may be a transmission assembly connected between the knob and the latch bolt in the related art, and the disclosure is not limited thereto. The release position of the present disclosure means that the knob 1 is in a non-pressed state, the knob 1 cannot be rotated, or the knob 1 can be rotated, but the rotation of the knob 1 cannot drive the transmission assembly to drive the latch bolt to rotate.

The present disclosure is not limited to the above-mentioned specific implementation of the knob 1 driving the latch bolt in the panel 3 to rotate in the pressed-in position to unlock or unlock the door, and any structure or method capable of achieving this function may be applied to the present disclosure, and the following describes an alternative embodiment thereof by way of example with reference to the accompanying drawings.

According to an embodiment of the present disclosure, as shown in fig. 1 and 2, a limiting member 4 fixed to the knob 1 and the latch bolt may be disposed on an inner side of the panel 3. In the release position, the limiting member 4 is circumferentially clamped on the panel 3, i.e. circumferential rotation cannot occur; in the press-fit position, the stopper 4 is circumferentially separated from the face plate 3, and its circumferential rotation is not restricted. The limiting piece 4 is arranged between the knob 1 and the lock bolt, namely, the connection mode that the knob 1 in the related technology is directly connected with the lock bolt through the transmission assembly is changed, and the knob 1 is connected with the transmission assembly through the limiting piece 4, namely, the knob 1 can finally drive the lock bolt by firstly driving the limiting piece 4 to rotate. Like this, when locating part 4 circumference card ends when panel 3, rotatory knob 1 just can't transmit the spring bolt with rotatory power, when knob 1 was in the position of impressing, locating part 4 circumference broke away from in panel 3, and rotatory knob 1 can transmit the revolving force for transmission assembly through locating part 4 this moment. As shown in fig. 2, in the present disclosure, the limiting member 4 may be configured in a sleeve shape, the sleeve-shaped limiting member 4 may be disposed coaxially with the knob 1 to facilitate the knob 1 to drive the limiting member 4 to rotate, and the hollow area of the sleeve may also provide an operation space for the installation of the knob 1 and the limiting member 4. Of course, the shape of the stopper 4 is not limited in the present disclosure, and any structure that can achieve the above-described circumferential locking with or releasing from the panel 3 may be used in the stopper 4 of the present disclosure.

As a specific structure in which the stopper 4 and the face plate 4 can be circumferentially locked, as shown in fig. 2, a stopper groove 41 may be formed on an end surface of one of the stopper 4 and the face plate 3, and a stopper protrusion 32 that is matched with the stopper groove 41 may be formed on an end surface of the other. In the process that the limiting part 4 moves along the axial direction, at the release position, the limiting protrusion 32 is clamped into the limiting clamping groove 41, and the circumferential rotation of the limiting part 4 is limited by the limiting clamping groove 41; in the press-in position, the limiting protrusion 32 is separated from the limiting slot 41, the circumferential rotation of the limiting member 4 is not limited by the limiting slot 41, and the knob 1 can drive the limiting member 4 to rotate. It should be understood that the disclosure is not limited to the circumferential locking structure, and any structure or method capable of achieving the circumferential locking of the limiting member 4 and the panel 3 may be applied to the disclosure, for example, the end surface of the limiting member 4 may be provided with a limiting protrusion, and the panel 3 is provided with a stopping sheet, and in the releasing position, the limiting protrusion can be locked by the stopping sheet, so as to prevent the limiting member 4 from further rotating.

According to another embodiment of the present disclosure, the knob 1 may be selectively engaged with a driven component, which may be the transmission assembly for driving the rotation of the latch bolt described above, or an adaptor connected to the transmission assembly. In the pressed-in position, the knob 1 is engaged with the driven part to be able to drive the bolt; in the release position, rotation of the knob 1 does not actuate the deadbolt, as the knob 1 is disengaged from the driven member. For example, as shown in fig. 3, in the present embodiment, a column 4 ' fixedly connected to the transmission assembly may be provided, the column 4 ' is coaxial with the knob 1, and the column 4 ' is the above-mentioned adaptor. The knob 1 is provided with a recess matched with the section profile of the column 4 ', at a release position, the knob 1 is separated from the column 4', and the knob 1 and the column 4 'are in a relatively rotatable state, namely the column 4' is not driven to rotate although the knob 1 rotates; at the press-in position, the knob 1 moves along the axial direction, so that the column 4 'is inserted into the recess of the knob 1, and the column 4' can be driven to rotate together by rotating the knob 1, and then the lock tongue is driven to rotate so as to perform the operation of back locking or unlocking. Further, in order to ensure that the knob 1 can rotate the column 4 ', the cross section of the column 4' may be non-circular, such as a cross section as shown. Furthermore, according to another embodiment, the aforementioned cylinder 4 'may be a hollow cylinder, in which case the knob 1 may be designed in such a shape that it can be inserted with a form fit into the cylinder 4'. The form of the knob 1 driving the cylinder 4' is similar to the above process and will not be described in detail here.

It can be known from the above embodiments that the effect that the knob 1 drives the latch bolt in the pressed-in position and cannot drive the latch bolt in the released position can be achieved by various appropriate ways. In some embodiments, the knob 1 can be connected to the bolt in both positions (or connected to the bolt through an intermediate structure), but it is necessary to provide a limit structure on the panel 3 that can limit the rotation in the release position; in other embodiments, the knob 1 is selectively connected to the latch bolt (or to the latch bolt via an intermediate structure), so that the knob 1 can actuate the latch bolt only in the pressed-in position.

According to some embodiments, the knob 1 may comprise a body intended to be held by hand to be driven in rotation and a stem coaxially connected to the body and intended to project into the panel 3, the stem being intended to be connected to the above-mentioned stop 4 or to the cylinder 4'.

In the embodiment shown in fig. 2, a threaded hole may be opened at an end surface of the rod portion 12, a through hole 43 is formed at an end surface of the limiting member 4 close to the rod portion 12, and the knob 1 and the limiting member 4 are connected by a fastening member 5 which passes through the through hole 43 and is screwed into the threaded hole. That is, the knob 1 and the limiting member 4 can be detachably connected by means of a threaded connection. When the retaining element 4 is configured as a sleeve as described above, the fastening element 5 can protrude into the interior of the sleeve, in order to increase the space utilization of the component.

Further, the end of the rod 12 may be formed as a stepped shaft, the end of the stopper 4 is formed as a groove 42, the notch of the groove 42 abuts against the shoulder of the stepped shaft, and the bottom of the groove 42 abuts against the end face of the stepped shaft. The structure can enable the knob 1 and the limiting piece 4 to be tightly connected, the limiting piece 4 can synchronously rotate along with the knob 1, and therefore the situation that the knob 1 rotates in place due to the fact that the knob 1 and the limiting piece 4 rotate asynchronously is avoided, and the limiting piece 4 cannot drive the lock tongue to complete the operation of back locking.

According to an embodiment of the present disclosure, as shown in fig. 2 and 3, the back locking mechanism may further include an elastic member 2, the elastic member 2 being disposed between the knob 1 and the panel 3 and having an elastic force to drive the knob 1 away from the panel 3. When the knob 1 is in the released state, the elastic member 2 can drive the knob 1 to be maintained at a position away from the faceplate 3. Thus, when the back-locking operation is not required, the knob 2 can be always in the above-described locked state or in a state in which the lock tongue cannot be driven although it can be rotated, so that an erroneous operation can be avoided. The elasticity of the elastic member 2 can be set according to actual conditions, and the elastic member 2 can be compressed with a large force, for example, an adult needs to press the knob 1 with a small force to drive the elastic member 2, so that the locking operation can not be started even if the knob 1 is pressed carelessly due to the small force of children or pets.

In the present disclosure, the elastic member 2 may include a compression spring, one end of which abuts against the body 11 and the other end of which abuts against the outer side of the panel 3. In this case, the compression spring may not be fixedly connected to the knob 1 and the faceplate 3, but may only elastically abut against end surfaces thereof. Of course, the elastic element 2 and the knob 1 and the panel 3 may be connected together by a fixed connection, such as welding.

For example, in the embodiment shown in fig. 2, in the case that the knob 1 is configured to have the above-mentioned body 11 and the rod portion 12, the compression spring may be sleeved on the outside of the rod portion 12, when no pressing force is applied to the knob 1, the restoring force of the compression spring causes the knob 1 to move in the direction away from the panel 3, and the knob 1 drives the limiting member 4, so that the limiting member 4 is again circumferentially locked with the panel 3; when a force overcoming the elastic force of the compression spring is applied to the knob 1, the knob 1 drives the limiting member 4 to axially move and unlock, so that the knob can rotate. Or according to another embodiment, with reference to fig. 3, the compression springs may also comprise a plurality of springs, each of which is elastically urged between the knob 1 and the panel 3.

Further, the panel 3 may be provided with a groove for placing the elastic member 2, so as to prevent the elastic member 4 from being released from the panel 3. For example, referring to fig. 2, 5 and 6, in the case that the elastic member 2 is a compression spring sleeved on the rod portion 12, an annular groove 31 may be opened on the panel 3, and the compression spring is placed in the annular groove 31.

Further, as shown in fig. 2, 5 and 6, the outer side of the panel 3 may be formed with an inward recessed receiving groove 33, and the knob 1 is at least partially disposed in the receiving groove 33 to reduce the volume of the portion of the knob 1 protruding out of the panel 3, so as to further avoid the risk of being accidentally triggered by a child or a pet at home.

A fully operable lock-back mechanism provided in accordance with the present disclosure is described below with reference to fig. 4-6. As shown in fig. 5, when the knob 1 is at the releasing position, due to the elastic restoring force of the elastic member 2, the knob 1 has a tendency of moving towards a direction away from the panel 3, the knob 1 drives the limiting member 4 to move axially, so that the limiting slot 41 of the limiting member 4 is matched with the limiting protrusion 32 on the panel 3, the limiting member 4 is circumferentially clamped on the panel 3, and at this time, the knob 1 cannot be rotated to perform the anti-locking operation. When the anti-lock is needed, as shown in fig. 6, the knob 1 is pressed into the panel 3, the knob 1 overcomes the elastic restoring force of the elastic member 2, the knob 1 moves towards the panel 3, the knob 1 drives the limiting member 4 to move axially, so that the limiting clamping groove 41 of the limiting member 4 is separated from the limiting protrusion 32 on the panel 3, and the knob 1 can drive the limiting member 4 to rotate to perform the anti-lock operation.

According to a second aspect of the embodiments of the present disclosure, the present disclosure also provides a door lock including the above-described lock reversing mechanism. The door lock has all the beneficial effects of the back locking mechanism, and the description is omitted.

According to an embodiment of the present disclosure, the door lock may be an intelligent door lock, and the panel is a touch panel. The structure and the control method of the touch panel can adopt the structure and the control method in the related art, and the disclosure does not limit this. For example, a preset unlocking password is input through a virtual key on the touch panel, and the transmission system can drive the lock tongue to unlock.

According to a third aspect of the embodiments of the present disclosure, there is also provided a door including the door lock described above. The door has all the advantages of the door lock, and the description is omitted.
