Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 8, the safety mechanism of a lock body provided by the embodiment of the present invention includes: clutch mechanism and trigger bolt 9.
The clutch mechanism includes: the lock catch comprises a shifting block 3 which can be driven by a handle, a clutch seat 2 which can drive a main lock tongue to move, and a clutch piece 4 which can enable the shifting block 3 to be combined with and separated from the clutch seat 2. The trigger latch 9 is movably disposed, and the trigger latch 9 is connected to the clutch member 4.
When the trigger bolt 9 moves, the clutch piece 4 can be driven to move so that the shifting block 3 is combined with the clutch seat 2, and when the trigger bolt 9 moves into the lock shell, the shifting block 3 is combined with the clutch seat 2.
It can be understood that the shifting block 3 is driven by the handle, the rotation angle of the shifting block 3 is ± a, and the limiting position is provided. a is a set angle, and a specific value of a is set according to actual needs, for example, a is equal to 40 °, which is not limited in the embodiment of the present invention. The extension or retraction of the main bolt is mainly driven by the clutch seat 2, so the clutch seat 2 does not move, and the main bolt does not move.
It should be noted that the above-mentioned trigger latch 9 is connected with the clutch member 4, and the two may be directly connected or indirectly connected. The embodiment of the invention does not limit the connection structure of the two, as long as the connection structure can ensure that the trigger bolt 9 can drive the clutch piece 4 to move to combine the shifting block 3 with the clutch seat 2 when moving, and the shifting block 3 is combined with the clutch seat 2 when the trigger bolt 9 moves into the lock shell. The trigger bolt 9 and the clutch part 4 can be directly connected through abutting and can also be directly connected through bonding.
When the door is opened, the trigger bolt 9 extends out of the lock shell; in the door closing process, the handle is not lifted, and when the trigger bolt 9 contacts the door frame, the trigger lock 9 moves under the pushing of the door frame; when the door is closed, the spring bolt 9 is triggered to move into the lock shell. When the shifting block 3 is combined with the clutch seat 2, the clutch seat 2 rotates along with the shifting block 3; when the shifting block 3 is separated from the clutch seat 2, the clutch seat 2 cannot rotate along with the shifting block 3, namely, the shifting block 3 idles.
The working principle of the safety mechanism of the lock body provided by the embodiment of the invention is as follows:
in the door closing process, the trigger bolt 9 moves under the acting force of the door frame, and the trigger bolt 9 drives the clutch piece 4 to move; when the door is closed, the spring bolt 9 is triggered to move into the lock shell, the clutch piece 4 enables the clutch seat 2 to be combined with the shifting block 3, at the moment, the handle is lifted upwards, the shifting block 3 can be driven to rotate, the clutch seat 2 combined with the shifting block 3 rotates along with the shifting block 3, and the main spring bolt can be driven to extend out of the lock shell, so that the door locking is realized.
The safety mechanism of the lock body provided by the embodiment of the invention ensures that the combination of the clutch seat 2 and the shifting block 3 can be realized only when the door is closed by arranging the trigger bolt 9 and the clutch member 4, namely, the lifting of the handle can be realized to extend the main bolt.
In the safety mechanism of the lock body, the clutch piece 4 realizes the combination and separation of the shifting block 3 and the clutch seat 2, and various structures exist. For example, the shifting block 3 is sleeved and connected with the clutch seat 2, the clutch piece 4 can connect the shifting block 3 with the clutch seat 2, and the clutch piece 4 can also be separated from the shifting block 3 or the clutch seat 2; or the shifting block 3 and the clutch seat 2 are arranged side by side, when the clutch 4 enables the clutch seat 2 to move to the combination position, the clutch seat 2 is combined with the shifting block 3, and when the clutch 4 enables the clutch seat 2 to move to the separation position, the clutch seat 2 is separated from the shifting block 3. In order to facilitate the combination and the separation, and to reduce the occupied space, the former is preferably selected, specifically, the shifting block 3 is sleeved and connected with the clutch seat 2, and the triggering lock tongue 9 can drive the clutch piece 4 to move along the direction perpendicular to the axial direction of the clutch seat 2 when moving. It is understood that the axial direction of the clutch seat 2 is the axial direction of the shifting block 3.
In the above structure, the clutch seat 2 can be sleeved outside the shifting block 3 or sleeved inside the shifting block 3. For the convenience of installation, the clutch seat 2 is preferably sleeved outside the shifting block 3.
The clutch member 4 is movably disposed on the clutch holder 2, and the dial 3 has a clutch hole 301 capable of engaging with the clutch member 4.
It can be understood that, during the door closing process, when the handle is not lifted up, the clutch hole 301 is opposite to the clutch member 4, so as to ensure that the clutch member 4 enters the clutch hole 301 under the driving of the trigger bolt 9, and the clutch seat 2 is combined with the shifting block 3. When the clutch thimble is not in the clutch hole 301, the clutch seat 2 is separated from the shifting block 3. As the trigger bolt 9 moves, the clutch part 4 moves within the clutch seat 2.
The clutch holder 2 has a mounting hole 201 for mounting the clutch 4, and the clutch 4 is slidably mounted in the mounting hole 201.
In order to facilitate the sliding of the clutch member 4, the clutch member 4 is a clutch thimble. Of course, other shapes of clutch 4 may be selected, such as, but not limited to, clutch plates, etc.
The engaging hole 301 may be a through hole or a blind hole, which is not limited in the embodiments of the present invention.
After the door is closed, the door is opened again, the spring bolt 9 is triggered to extend out of the lock shell, and the clutch part 4 needs to be reset at the moment so as to ensure that the door is closed again and locked. The resetting of the clutch part 4 can be realized by the acting force of the trigger bolt 9, specifically, the trigger bolt 9 is fixedly connected with the clutch part 4, and when the trigger bolt 9 extends out of the lock shell, the trigger bolt 9 drives the clutch part 4 to move so as to separate the clutch seat 2 from the shifting block 3.
The trigger bolt 9 is fixedly connected with the clutch part 4, and when the trigger bolt 9 is directly connected with the clutch part 4, the trigger bolt 9 is directly and fixedly connected with the clutch part 4; when the trigger latch 9 is indirectly connected with the clutch member 4, for example, the trigger latch 9 is indirectly connected with the clutch member 4 through a transmission mechanism, the trigger latch 9 is indirectly fixedly connected with the clutch member 4 through the transmission mechanism.
Of course, resetting of clutch 4 can be achieved in other ways. Specifically, a reset elastic member is arranged in the clutch seat 2, and the reset elastic member can deform along the moving direction of the clutch member 4, specifically, one end of the reset elastic member is connected with the clutch seat 2, and the other end of the reset elastic member is connected with the clutch thimble.
When the clutch 4 does not enter the engaging hole 301, the return elastic member is kept as it is, and after the clutch 4 enters the engaging hole 301, the return elastic member is compressed. After the door is opened, the spring bolt 9 is triggered to extend out of the lock shell, and the clutch part 4 is reset under the restoring force of the reset elastic part, so that the reset is facilitated.
In the above structure, the clutch member 4 is connected to the trigger latch 9, and specifically, the clutch member 4 is connected to the trigger latch 9 by abutment. The clutch part 4 is abutted against the trigger bolt 9, namely the clutch part 4 is directly connected with the trigger bolt 9; or the trigger bolt 9 is abutted against the clutch part 4 through a connecting part, namely the trigger bolt 9 is indirectly connected with the clutch part 4 through the connecting part. When the trigger bolt 9 extends out of the lock shell, the trigger bolt 9 can not apply acting force to the clutch part 4, and the clutch part 4 is reset only by the restoring force of the reset elastic part.
In order to facilitate the resetting, the resetting elastic piece is a resetting spring.
In order to improve the resetting reliability, it is preferable that the clutch member 4 is reset by the restoring force of the reset elastic member and the force applied to the clutch member 4 by the trigger latch 9.
In order to trigger the lock tongue 9 to drive the clutch piece 4 to move, so that the clutch seat 2 is combined with the shifting block 3. Preferably, the triggering latch 9 is indirectly connected to the clutch member 4. In particular, the trigger bolt 9 is connected to the clutch 4 via a transmission mechanism. In particular when the clutch member 4 is moved in a direction perpendicular to the axial direction of the clutch seat 2.
The moving direction of the clutch piece 4 can be vertical to or parallel to the moving direction of the triggering bolt 9. In order to avoid the triggering bolt 9 from influencing the setting of the main bolt, the moving direction of the clutch part 4 is preferably perpendicular to the moving direction of the triggering bolt 9.
When the moving direction of the clutch member 4 is perpendicular to the moving direction of the trigger latch 9, there are various transmission mechanisms for converting the horizontal motion into the vertical motion, such as a slider mechanism, a slanting wedge mechanism, a pulley mechanism, etc., which can be designed according to actual requirements.
For improving the reliability, the transmission mechanism is preferably a slanting wedge mechanism, specifically, the driving member 11 of the slanting wedge mechanism is connected with the trigger bolt 9, and the force-bearing member 8 of the slanting wedge mechanism is connected with the clutch member 4.
The force-receiving member 8 may be directly or indirectly connected to the clutch member 4. The design is carried out according to actual needs.
Further, the driving member 11 is a driving rod, and the stressed member 8 has a first guide groove 801 and a second guide groove 802 which is communicated with the first guide groove 801 and is relatively obliquely arranged; the length direction of the second guide groove 802 is the same as the moving direction of the trigger bolt 9, and both the second guide groove 802 and the first guide groove 801 are in sliding fit with the driving rod.
It will be appreciated that the first channel 801 and the second channel 802 are in communication along the length of the second channel 802.
For ease of installation, one side of the first channel 801 has an opening for entry of the active lever. The plane of the opening of the first guide groove 801 and the plane of the notch of the first guide groove 801 are perpendicular to each other.
The inclination direction of the first guide groove 801 needs to be designed according to the relative positions of the first guide groove 801 and the second guide groove 802. Specifically, the end of the first guide groove 801 far away from the second guide groove 802 is a first end, and the end of the first guide groove 801 near the second guide groove 802 is a second end. When the first guide groove 801 is located at a side of the second guide groove 802 close to the clutch seat 2, the first guide groove 801 is inclined from the second end to the first end thereof in a direction close to the clutch seat 2; when the first guide groove 801 is located on the side of the second guide groove 802 away from the clutch seat 2, the first guide groove 801 is inclined from the second end to the first end thereof in a direction away from the clutch seat 2.
Of course, the wedge mechanism may be other structures, for example, the driving member 11 has a first wedge surface, and the force-receiving member 8 has a second wedge surface cooperating with the first wedge surface, and is not limited to the above embodiment.
In the safety mechanism of the lock body, the trigger bolt 9 can be positioned at the lower side of the clutch seat 2 and also can be positioned at the upper side of the clutch seat 2. In order to reduce the volume of the entire lock body, it is preferred that the triggering bolt 9 is located on the underside of the clutch seat 2.
It is understood that "upper side" and "lower side" refer to the upper side and the lower side, respectively, in the vertical direction after the entire lock body is installed on the door.
In order to further optimize the above technical solution, the safety mechanism of the lock body further comprises a force-storing elastic member 5.
When the shifting block 3 is in a first state, the shifting block 3 limits the movement of the clutch piece 4 to limit the combination of the shifting block 3 and the clutch seat 2, and the force storage elastic piece 5 stores the driving acting force generated when the trigger bolt 9 moves; when the shifting block 3 is in the second state, the shifting block 3 releases the limitation on the clutch piece 4, the force storage elastic piece 5 releases the driving acting force, and the driving acting force drives the clutch piece 4 to move so that the shifting block 3 is combined with the clutch seat 2.
It can be understood that when the handle is not lifted up, the shifting block 3 is in the second state; after the handle is lifted up, the shifting block 3 is in the first state.
Taking fig. 5 as an example, when the handle is not lifted up, the clutch hole 301 is opposite to the clutch piece 4, and the shifting block 3 is in the second state, at this time, the clutch piece 4 can realize the combination of the clutch seat 2 and the shifting block 3; taking fig. 8 as an example, after the handle is lifted up, the clutch hole 301 is staggered from the clutch piece 4, and the shifting block 3 is in the first state, at this time, the clutch piece 4 cannot realize the combination of the clutch seat 2 and the shifting block 3.
In the structure, when the lifting handle is used for closing the door, the shifting block 3 is in the first state, namely the shifting block 3 rotates by a preset angle, the shifting block 3 limits the movement of the clutch piece 4 to limit the clutch piece 4 to enable the shifting block 3 to be combined with the clutch seat 2, at the moment, the lifting handle cannot enable the main bolt to extend out, namely, the door cannot be locked, and the main bolt cannot collide with the door frame. When the handle is lifted to close the door, the driving force generated when the trigger bolt 9 moves is stored by the storing force elastic member 5. After the door is closed, the handle is loosened, the handle returns to the original position, the shifting block 3 also returns to the original position along with the handle, at the moment, the shifting block 3 releases the limitation on the clutch piece 4, the clutch piece 4 moves, and the shifting block 3 is combined with the clutch seat 2. And lifting the handle again, and extending the main bolt to complete the door locking.
The safety mechanism of the lock shell avoids damaging the internal structure of the lock body and also avoids collision between the main bolt and the door frame in the door closing process of the upper carrying handle; moreover, the door can be closed by lifting the handle, so that the reliability and convenience are improved.
The arrangement mode of the elastic force storage part 5 depends on the connection relationship between the trigger bolt 9 and the clutch part 4. When the trigger bolt 9 is directly connected with the clutch part 4, the force storage elastic part 5 is connected with the trigger bolt 9 and the clutch part 4, and the force storage elastic part 5 can deform along the movement direction of the clutch part 4.
When the trigger bolt 9 is connected with the clutch part 4 through the transmission mechanism, the force storage elastic part 5 is connected with the transmission mechanism and the clutch part 4, and the force storage elastic part 5 can deform along the movement direction of the clutch part 4.
Of course, the above-mentioned force-storing elastic member 5 may alternatively be provided in the transmission mechanism. Specifically, the transmission mechanism includes: the first transmission piece is connected with the trigger bolt 9, and the second transmission piece 7 is connected with the clutch piece 4; the second transmission piece 7 and the first transmission piece can move relatively, and the force storage elastic piece 5 is connected with the first transmission piece and the second transmission piece 7.
It will be appreciated that, in the direction of movement of clutch member 4, the force-storing elastic member 5 is able to deform; the second transmission element 7 and the first transmission element can be moved relative to each other in the direction of movement of the clutch element 4.
The second transmission member 7 and the first transmission member can move relatively, for example, the first transmission member and the second transmission member 7 are connected by a fastening member 6, and the first transmission member and the second transmission member 7 are provided with a placement hole for installing the fastening member 6, and the placement hole is strip-shaped. In particular, the fastener 6 is a rivet or a screw. Of course, the second transmission member 7 and the first transmission member may be selected to move relative to each other through other connection structures, and are not limited to the above embodiments.
When the first transmission piece moves under the driving of the trigger bolt 9, the second transmission piece 7 is also limited to move because the shifting block 3 limits the movement of the separating piece 4, the second transmission piece 7 is kept still, namely the first transmission piece moves relative to the second transmission piece 7, so that the force storage elastic piece 5 is deformed, and the force storage elastic piece 5 stores the acting force of the trigger bolt 9 on the first transmission piece, namely the driving acting force generated when the trigger bolt 9 moves; when the shifting block 3 releases the limitation on the separating piece 4, the separating piece 4 and the second transmission piece 7 can move, and under the action of the restoring force of the elastic force storage piece 5, the separating piece 4 and the second transmission piece 7 move, so that the clutch seat 2 is combined with the shifting block 3.
Preferably, the storage elastic member 5 is a storage spring. When the first transmission member moves relative to the second transmission member 7, the force storage spring can be compressed or stretched, and is specifically set according to actual requirements.
In order to facilitate the installation of the force storage elastic member 5, the first transmission member is provided with a first hook leg, the second transmission member 7 is provided with a second hook leg, and two ends of the force storage elastic member 5 are respectively hooked on the first hook leg and the second hook leg.
When the transmission mechanism is an inclined wedge mechanism, a driving piece 11 of the inclined wedge mechanism is connected with a trigger bolt 9, and a stress piece 8 of the inclined wedge mechanism is connected with the clutch piece 4, the first transmission piece is the stress piece 8. The slanting wedge mechanism further comprises a second transmission member 7. In particular, please refer to the above.
It should be noted that "lock door is realized" as described herein, and may be "lock back is realized".
In order to embody the present invention more specifically, the following describes each state of the safety mechanism of the lock body in combination with a specific structure:
as shown in fig. 5 and 6, in the door opening state, the triggering bolt 9 extends out of the lock shell, because of the action of the first guide groove 801, the second transmission piece 7 and the stressed piece 8 move downwards, the clutch piece 4 moves downwards through the action of the reset elastic piece in the clutch seat 2, at the moment, the clutch piece 4 is in the non-working state, the lifting handle cannot drive the clutch seat 2 to rotate, and only the shifting block 3 rotates without work.
As shown in fig. 7, in the door-closed state, since the triggering bolt 9 is forced to move into the lock case, the second transmission member 7 and the stressed member 8 are driven to move upwards through the first guide groove 801, the clutch member 4 is also lifted, the clutch member 4 is in the working state, and at this time, the handle can be lifted up, so that the main bolt is extended.
The second transmission piece 7 and the stressed piece 8 can move relatively, and when the second transmission piece 7 is not moved, the stressed piece 8 can move upwards relative to the second transmission piece 7; when the force-bearing member 8 is not moved, the second transmission member 7 can move downwards relative to the force-bearing member 8, and the position relationship between the second transmission member 7 and the force-bearing member 8 is reset through the force-storing elastic member 5.
