Description

Technical Field

[0001] The utility model relates to the field of locks, and particularly to a handle dialing component and a lock body in which the inside and outside doors do not interfere with each other when opening and closing the door. Background Art

[0002] In modern family and office environments, mortise locks are widely used because of their simple installation and convenient use. In recent years, with the development of intelligent lock technology, many mortise locks have integrated electronic drive clutch control devices, enabling the locks to be unlocked not only by traditional keys but also by various methods such as electronic keys, passwords, and even biometric identification, greatly improving the user experience.

[0003] However, there is a problem with existing mortise locks with electronic drive clutch control devices, that is, when unlocking by operating the handle from outside the door, the handle inside the door will also rotate together with the handle outside the door. Although this synchronous rotation design simplifies the lock structure, it brings several inconveniences in practical applications.

[0004] First of all, the synchronous rotation of the inside and outside handles increases the torque required to open the door. Especially when the handle inside the door is resisted or fixed, the handle outside the door cannot rotate either; conversely, when the handle outside the door is resisted or fixed, the handle inside the door cannot rotate either, resulting in the door being unable to be opened normally. This problem is particularly serious in emergency situations. For example, during a fire or earthquake, if the people inside the door fix the handle inside the door to prevent external intrusion, the rescue personnel outside the door will not be able to open the door for rescue by normal means.

[0005] Secondly, if someone deliberately fixes the handle inside or outside the door (such as using additional security measures), the door cannot be opened even if the handle on the opposite side is rotated. This situation not only affects the normal entry and exit of legitimate users but may also pose serious safety hazards in emergency situations.

[0006] Therefore, how to overcome the above-mentioned defects has become an important issue that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0013] Furthermore, the middle peach also includes a first limiting protrusion arranged on the limiting portion on the side facing the inner handle peach, and a second limiting protrusion arranged on the side facing the outer handle peach.

[0014] A lock body with non-interference in inner and outer door opening, including a handle-push peach assembly as described in the present case, and also including a lock shell and a lock shell cover, wherein a square tongue assembly, an inclined tongue assembly, a safety tongue assembly, a lock core drive assembly and a motor drive assembly are installed in the lock shell, and the square tongue assembly is linked to the handle-push peach assembly through a first linkage piece so that the square tongue assembly can be driven to move through the lock core drive assembly or the motor drive assembly.

[0015] Further, the inner handle cam includes a third boss disposed towards the inside, the first linkage is movably sleeved on the third boss, a sliding hole is formed at the upper end of the first linkage, the first limiting protrusion is placed in the sliding hole so as to rotate following the middle cam when the middle cam rotates, a plurality of first gear teeth are provided at one end of the first linkage, and a second through hole is formed in the first linkage.

[0016] Further, the outer handle cam includes a fourth boss disposed towards the outside, a second linkage is sleeved on the fourth boss, a third through hole is formed in the second linkage, one end of the second linkage abuts against the second limiting protrusion so as to rotate following the middle cam when the middle cam rotates, the rotation direction of the second linkage is opposite to that of the second dial, and the upper end of the second linkage abuts against the inclined tongue assembly to drive the inclined tongue assembly to retract.

[0017] Further, the square tongue assembly includes a square lock tongue that can extend / retract relative to the lock case, a lock tongue connecting plate that is fixedly connected to one end of the square lock tongue and is installed in the lock case and can drive the square lock tongue to move, and a third linkage that is linked and connected below the lock tongue connecting plate and can drive the lock tongue connecting plate to move. A plurality of second gear teeth are provided at one end of the third linkage, and an abutting portion is provided at the other end. The second gear teeth are meshed with the first gear teeth.

[0018] Further, the square tongue assembly further includes a fourth linkage that is movably connected to the upper part of the lock tongue connecting plate. A convex plate is provided on the second linkage. The other end of the fourth linkage is disposed below the second linkage and abuts against the convex plate. The upper end of the second linkage abuts against the inclined tongue assembly to drive the inclined tongue assembly to extend and retract.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1. This case provides a handle peach component with a three - layer peach structure. The handle peach component in this case adopts a three - layer peach structure. The inner handle peach and the outer handle peach are respectively embedded on the inner and outer sides of the middle peach. The inner handle peach and the outer handle peach separately control the middle peach, thereby driving the middle peach to rotate to achieve locking / unlocking. A clutch pin is hooked at the upper end of the middle peach. The clutch pin hangs above the first chute and the second chute. In the initial state, the inner handle peach drives the middle peach to rotate synchronously through the limiting structure, and the outer handle peach does not rotate synchronously. At this time, the outer handle peach rotates idly. When the clutch pin is driven to move downward and can enter the first chute and the second chute, rotating the outer handle peach at this time can drive the clutch pin to slide in the first chute and the second chute, thereby driving the middle peach to rotate, and the inner handle peach does not rotate synchronously. The rotation direction of the inner handle peach is opposite to that of the outer handle peach to facilitate the user to open the door inside and outside the door respectively. Specifically in implementation, the clutch pin is used to cooperate with the motor drive assembly to achieve the clutch function. When the motor drive assembly drives the clutch pin to move downward and enter the first chute and the second chute, rotating the outer handle peach at this time can drive the middle peach to rotate, thereby achieving opening and closing the door. Under normal conditions, due to the separation of the inner and outer handle peaches, the outer handle peach is always in an idle rotation state. At this time, the inner handle peach can drive the middle peach to rotate through the limiting structure, thereby achieving opening and closing the door. The handle peach component of this case can be installed in different lock bodies, which can effectively solve the problem that the inner and outer door handles do not interfere with each other when rotating, and realizes the separate operation of the inner and outer handles. In this way, even if the inner door handle is fixed, the outer door handle can still rotate freely and complete the unlocking action, greatly improving the convenience and safety of use. Through the design of the three - layer peach structure in this case, the torque required to open the door is reduced at the same time, and it is ensured that the door can be opened timely and smoothly under any circumstances. Since the inner and outer handle peaches no longer rotate synchronously, unnecessary friction and resistance are reduced, making it easier to open the door.

[0021] 2. This case also provides a lock body with non - interfering inner and outer door openings including the above - mentioned handle peach component. Through optimizing the internal structure design, the lock body realizes the separate control of the inner and outer handle operations and can achieve the independent operation of the inner and outer handles in different working modes. When linkage is not required, the inner handle can be operated independently without affecting the state of the outer handle; vice versa. By selecting the lock core drive assembly or the motor drive assembly, multiple unlocking methods can be supported, which not only retains the convenience of traditional keys but also introduces the intelligence of electronic drive. The first linkage piece connects the handle peach component with the square tongue component, so that whether driven by the lock core or the motor, the square tongue component and the diagonal tongue component can be extended or retracted, ensuring the normal opening and closing of the door. It significantly improves the practicality and safety of the lock, and at the same time provides a more flexible and convenient use experience. Brief Description of the Drawings

[0033] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0034] Regarding the descriptions of the positional relationships of components such as front, rear, top, bottom, left, right, inner, and outer in this case, please refer to Figure 2 、 Figure 3 for the shown orientations.

[0035] Such as Figures 2 to 4As shown in the figure, this case provides a handle peach-picking component, which includes an intermediate peach-picking part 1, an inner handle peach-picking part 2, and an outer handle peach-picking part 3 arranged coaxially. The inner handle peach-picking part 2 and the outer handle peach-picking part 3 are respectively embedded on the inner and outer sides of the intermediate peach-picking part 1. The interaction between these three peach-picking parts is realized through a specific chute structure and a clutch pin 4. Specifically, a first chute 21 is provided on the inner handle peach-picking part 2, and second chutes 31 symmetrical to the first chute 21 are arranged on the outer handle peach-picking part 3. That is to say, the first chute 21 and the second chute 31 are the same in size and structure, and when the handle peach-picking component of this case is assembled, the two are symmetrically arranged with each other. A clutch pin 4 is hooked at the upper end of the intermediate peach-picking part 1. Under normal conditions, the clutch pin 4 hangs above the first chute 21 and the second chute 31. In specific implementation, the clutch pin 4 is driven to move up and down through a motor drive component, so as to realize the clutch switching between the outer handle peach-picking part and the intermediate peach-picking part. In the initial state, the inner handle peach-picking part 2 drives the intermediate peach-picking part 1 to rotate synchronously through a limiting structure, and the outer handle peach-picking part 3 does not rotate synchronously. At this time, the outer handle peach-picking part 3 rotates idly; when the clutch pin 4 is driven to move downward and can enter the first chute 21 and the second chute 31, at this time, rotating the outer handle peach-picking part 3 can drive the clutch pin 4 to slide in the first chute 21 and the second chute 31, thereby driving the intermediate peach-picking part 1 to rotate, and the inner handle peach-picking part 2 does not rotate synchronously. The rotation direction of the inner handle peach-picking part 2 is opposite to that of the outer handle peach-picking part 3, so as to facilitate opening the door inside and outside. When one of the inner handle peach-picking part 2 or the outer handle peach-picking part 3 is operating, the other handle peach-picking part will be in a static state, avoiding the extra torque and operation complexity brought by their synchronous rotation. The handle peach-picking component of this case realizes the separation of the inner handle peach-picking part 2 and the outer handle peach-picking part 3. When the clutch pin 4 moves downward and enters the first chute 21 and the second chute 31, the outer handle peach-picking part 3 can drive the intermediate handle peach-picking part 1 to rotate, so as to realize opening the door outside the door. Because the rotation direction of the inner handle peach-picking part 2 is opposite to that of the outer handle peach-picking part 3, at this time, the inner handle peach-picking part 2 is in a static idling state. When internal door opening is required, rotating the inner handle peach-picking part 2 drives the intermediate handle peach-picking part 1 to rotate through a limiting structure. Because the rotation direction of the inner handle peach-picking part 2 is opposite to that of the outer handle peach-picking part 3, at this time, the outer handle peach-picking part 3 is in a static idling state. It should be noted that in specific implementation, the user can change the lengths of the first chute 21 and the second chute 31, so as to shorten or extend the stroke of the clutch pin 4 in the first chute 21 and the second chute 31, thereby realizing door opening methods with different rotation angles to meet the door opening requirements in different scenarios. Through the position change of the clutch pin 4 in this case, the separate control of the inner and outer handles can be realized. When external operation is required, the outer handle peach-picking part 3 can be operated alone without affecting the state of the inner handle peach-picking part 2, and vice versa. In specific implementation, the rotation angles of the inner and outer handles are generally 30-45 degrees, so that door opening is faster and more convenient, and the user can design it according to needs.

[0036] Further, continue to refer toFigures 2 to 4 As shown, the limiting structure includes a screw 5 detachably installed on the middle peach-shaped handle 1. One end of the inner handle peach-shaped handle 2 abuts against the screw 5, so that the middle peach-shaped handle 1 is driven to rotate by the screw 5. A screw hole 11 for the screw 5 to pass through is provided on the middle peach-shaped handle 1. The screw hole 11 is a through hole, and the end of the screw 5 is parallel to the wall surface of the middle peach-shaped handle 1 to prevent the end of the screw 5 from interfering with the rotation of the outer handle peach-shaped handle. The screw 5 can also play a role in changing the opening direction and changing the inside-outside opening mode. After being normally installed, generally the screw head of the screw 5 is arranged towards the inner handle peach-shaped handle 2. During specific implementation, the user can unscrew the screw 5, change the direction, make the screw head of the screw 5 face the outer handle peach-shaped handle 3, and the end of the screw face the inner handle peach-shaped handle 2. In this way, by the limitation between the screw 5 after changing the direction and the outer handle peach-shaped handle 3, the opening direction and the inside-outside opening mode are changed, significantly improving the practicability and flexibility of the handle peach-shaped handle assembly in this case and being able to adapt to different installation requirements.

[0037] Specifically, continue to refer to Figures 2 to 4 As shown, for the convenience of connecting the inner handle peach-shaped handle 2 and the outer handle peach-shaped handle 3 to the middle peach-shaped handle 1, a first through hole 12 is opened on the middle peach-shaped handle 1. The inner handle peach-shaped handle 2 and the outer handle peach-shaped handle 3 are respectively embedded in the first through hole 12, making the installation of the inner handle peach-shaped handle 2 and the outer handle peach-shaped handle 3 simpler and reducing the installation time and complexity. The inner handle peach-shaped handle 2 includes an inner handle through hole 22, which is convenient for connecting the inner handle during installation. The inner handle peach-shaped handle 2 further includes a first boss 23 arranged towards the first through hole 12 and embedded in the first through hole 12, so as to be more stably embedded in the first through hole 12, stably connect with the middle peach-shaped handle 1, and improve the reliability of the entire handle peach-shaped handle assembly. At the same time, the setting of the first boss 23 helps the inner handle peach-shaped handle 2 to rotate stably in the first through hole 12. The inner handle peach-shaped handle 2 further includes a first groove 24 opened in the first boss 23, and a separator 6 is embedded in the first groove 24 to prevent the excessive extension of the inner handle from affecting the separate rotation of the inner handle peach-shaped handle 2 and the outer handle peach-shaped handle 3 when connecting the inner handle in the inner handle through hole 22. The outer handle peach-shaped handle 3 includes an outer handle through hole 32 and a second boss 33 arranged towards the first through hole 12 and embedded in the first through hole 12. The function of the second boss 33 here is the same as that of the first boss 23, so no more details will be described. During specific implementation, for the convenience of installing the handle peach-shaped handle assembly in this case, the first through hole 12 is set to be circular, and the inner handle through hole 22 and the outer handle through hole 32 are set to be common squares that are easy to match with the door handle, and the inner handle through hole 22 and the outer handle through hole 32 have the same size and structure, so that the adaptability is better and it is easy to install.

[0038] Continue to refer to Figures 2 to 4As shown in the figure, further, limiting parts 13 are symmetrically arranged on both the inner and outer sides of the middle dial 1, and are integrally formed with the middle dial 1. The clutch pin 4 is hooked on the limiting part 13. Through the structural design of the limiting part 13, the clutch pin 4 can maintain stability during the up-and-down movement and be docked with the first sliding groove 21 and the second sliding groove 31 at appropriate positions, realizing the separation control of the inner handle dial 2 and the outer handle dial 3, ensuring the stability of the clutch pin 4 during the up-and-down movement, and avoiding the problem of the linkage failure of the inner handle dial 2 and the outer handle dial 3 caused by the instability of the clutch pin 4. The limiting part 13 includes a first limiting end 131 and a second limiting end 132. The first limiting end 131 and the second limiting end 132, as the two ends of the limiting part, provide a positioning reference for the rotation of the inner handle dial 2 and the outer handle dial 3, ensuring the consistency and accuracy of the rotation. Among them, the first limiting end 131 limits the rotation of the inner handle dial 2 and the outer handle dial 3 towards the first limiting end 131, and the second limiting end 132 limits the rotation of the inner handle dial 2 and the outer handle dial 3 towards the second limiting end 132, thereby preventing the inner handle dial 2 and the outer handle dial 3 from rotating excessively. For the convenience of limiting cooperation with the limiting part 13 and at the same time facilitating the limiting cooperation with the screw 5 on the middle dial 1, the inner handle dial 2 of this case includes a first dial piece 25 and a second dial piece 26, and the outer handle dial 3 includes a third dial piece 34 symmetrically arranged with the first dial piece 25 and a fourth dial piece 35 symmetrically arranged with the second dial piece 26. By limiting the excessive rotation of the inner handle dial 2 and the outer handle dial 3 through the limiting part 13, the safety hazards and the situation of being unable to unlock caused by improper operation are avoided. The symmetric arrangement between the limiting part 13, the third dial piece 34 symmetrically arranged with the first dial piece 25, and the fourth dial piece 35 symmetrically arranged with the second dial piece 26 ensures the stability of the inner handle dial 2 and the outer handle dial 3 during the rotation process, reducing unnecessary shaking and wear. The design of the limiting part 13 makes the user operate the inner handle dial 2 and the outer handle dial 3 more smoothly, reduces unnecessary resistance, and improves the comfort of operation.

[0039] To adapt and install the handle dial assembly of this case on different lock bodies and connect and drive with other components of the lock body, such as Figures 2 - 4 As shown in the figure, the middle dial 1 of this case further includes a first limiting convex block 133 arranged on the limiting part 13 on the side facing the inner handle dial 2 and a second limiting convex block 14 arranged on the side facing the outer handle dial 3. At the same time, the setting of the second limiting convex block 14 is beneficial to further limit the rotation angle of the outer handle dial 3. When not assembled and fixed, the third dial piece 34 and the fourth dial piece 35 respectively abut against the second limiting convex block 14 when rotating to the maximum angle, making the rotation of the outer handle dial 3 more controllable and avoiding the locking failure or safety problems caused by excessive rotation.

[0040] As Figures 1 - 11As shown in the figure, this case also provides a lock body where the inner and outer door openings do not interfere with each other, including a handle dial cam component 1000 described above in this case. It also includes a lock case 100 and a lock case cover 101. The lock case 100 and the lock case cover 101 are the basic structural frameworks of the lock body, used to accommodate and protect the components inside the lock body. Inside the lock case 100, a square tongue component 200 is installed, which is responsible for performing the locking or unlocking function, an oblique tongue component 300, which assists the square tongue component 200 to improve the sealing and safety of the lock, a safety tongue component 400, which provides additional safety protection to prevent unauthorized opening, a lock core drive component 500, which is used for the locking and unlocking operations of traditional keys, and a motor drive component 600, which is used for the unlocking operation in the electronic drive mode. The square tongue component 200 is linked and connected to the handle dial cam component through the first linkage piece 7, so that the square tongue component 200 can be driven to extend / retract into / out of the lock case 100 through the lock core drive component 500 or the motor drive component 600. Thus, whether driven by the lock core or the motor, the extension or retraction of the square tongue component 200 can be achieved, ensuring the normal opening and closing of the door. The lock body provided in this case, where the inner and outer door openings do not interfere with each other, can realize the independent operation of the inner and outer handles in different working modes by setting the handle dial cam component 1000. When linkage is not required, the inner handle can be operated independently without affecting the state of the outer handle; vice versa. Through the selection of the lock core drive component 500 or the motor drive component 600, multiple unlocking methods can be supported, retaining the convenience of traditional keys and introducing the intelligence of electronic drive. The setting of the lock core drive component 500 can handle the situation where the motor may be damaged or there is no power and the door cannot be opened.

[0041] As Figures 5 - 9 shown, further, to facilitate the connection between the first linkage piece 7 and the inner handle dial 2, the inner handle dial 2 includes a third boss 27 arranged towards the inside. A second through hole 73 is formed on the first linkage piece 7. The first linkage piece 7 is movably sleeved on the third boss 27 through the second through hole 73 and does not rotate with the inner handle dial 2. A sliding hole 71 is formed at the upper end of the first linkage piece 7. The first limiting convex block 133 is placed in the sliding hole 71 and thus rotates with the middle dial 1 when the middle dial 1 rotates. This structure has high transmission efficiency and stability. During specific implementation, the length of the sliding hole 71 can be set to determine the sliding stroke of the first limiting convex block 133 in the sliding hole 71, thereby setting the rotation angle for locking / unlocking. One end of the first linkage piece 7 is provided with a number of first gear teeth 72. The first gear teeth 72 are convenient for meshing with the second gear teeth 2031, thereby generating linkage and driving the square tongue component 200 to extend / retract relative to the lock case 100 to achieve the opening or closing of the door. The way of gear meshing provides better smoothness and reliability for the lock body in this case where the inner and outer door openings do not interfere with each other.

[0042] Continue to refer to Figures 5 - 9As shown in the figure, the outer handle cam 3 of this case includes a fourth boss 36 disposed towards the outside. A second linkage piece 8 is sleeved on the fourth boss 36. The setting of the fourth boss 36 facilitates the connection between the second linkage piece 8 and the outer handle cam 3. Specifically, when implemented, a third through hole 81 is also provided on the second linkage piece 8. The second linkage piece 8 is movably sleeved on the outer handle cam 3 through the third through hole 81 and does not rotate with the outer handle cam 3. One end of the second linkage piece 8 abuts against the second limiting boss 14, and thus rotates with the intermediate cam 1 when the intermediate cam 1 rotates. The second linkage piece 8 rotates in the opposite direction to the second dial piece 26. The setting of the second linkage piece 8 is used to transmit the rotation of the outer handle cam 3 to the square tongue assembly 200, thereby driving the square tongue assembly 200 to extend / retract relative to the lock housing 100, realizing the opening or closing of the door. The upper end of the second linkage piece 8 abuts against the oblique tongue assembly 300 to drive the oblique tongue assembly 300 to retract, thereby realizing the opening of the door.

[0043] As Figure 1 , Figure 4 , Figure 5 , Figure 10 , Figure 11 As shown in the figure, the square tongue assembly 200 of this case includes a square lock tongue 201 that can extend / retract relative to the lock housing 100, a lock tongue connecting plate 202 fixedly connected to one end of the square lock tongue 201 and installed in the lock housing 100, which can drive the square lock tongue 201 to move, and a third linkage piece 203 linked and connected below the lock tongue connecting plate 202, which can drive the lock tongue connecting plate 202 to move. One end of the third linkage piece 203 is provided with a number of second gear teeth 2031, and the other end is provided with an abutting portion 2032. The second gear teeth 2031 are engaged with the first gear teeth 72, thereby realizing the linkage with the first linkage piece 7. In this way, the linkage between the square tongue assembly 200 and the handle cam assembly 1000 is realized. Whether it is mechanical or electronic locking / unlocking, the rotation of the intermediate cam 1 can drive the rotation of the first linkage piece 7, and then drive the rotation of the third linkage piece 203, thereby driving the square tongue assembly 200 to achieve. The setting of the abutting portion 2032 is for the lock core cam of the lock core driving assembly 500 to abut when rotating, thereby driving the third linkage piece 203 to act and reversely driving the first linkage piece 7 to drive the intermediate cam 1 to rotate. In this way, when locking the door with the lock core inside the door, in case the lock core driving assembly 500 is not reset, the handle outside the door can still be rotated to retract the square tongue assembly 200 completely, avoiding the situation that the square tongue assembly 200 cannot be retracted completely and jams the door panel and cannot open the door when the motor or mechanical unlocking is performed. Through reasonable structural design, the efficient transmission and stable connection between the square tongue assembly 200, the first linkage piece 7, and the third linkage piece 203 are realized, significantly improving the transmission efficiency and reliability of the lock, while simplifying the operation process and enhancing the user experience.

[0044] Continuing as Figure 1 , Figure 4 , Figure 5 ,Figure 10 , Figure 11 As shown, further, the square tongue component 200 of this case further includes a fourth linkage piece 204 with one end movably connected above the lock tongue connecting plate 202. Specifically, during implementation, the fourth linkage piece 204 is rotatably connected to the lock tongue connecting plate 202 through a pin shaft. A convex plate 81 is provided on the second linkage piece 8. The other end of the fourth linkage piece 204 is disposed below the second linkage piece 8 and abuts against the convex plate 81. The upper end of the second linkage piece 8 abuts against the inclined tongue component 300 to drive the inclined tongue component 300 to extend and retract. Through the linkage connection between the second linkage piece 8 and the fourth linkage piece 204, the second linkage piece 8 can drive the fourth linkage piece 204 to rotate to drive the inclined tongue component 300 to extend and retract, thereby realizing opening and closing of the door. Specifically, during implementation, in the movement state where the lock tongue connecting plate 202 extends and retracts relative to the lock housing 100, the end of this end of the fourth linkage piece 204 abuts against the lock core driving component 500, thereby realizing mechanical locking and unlocking of the lock core driving component 500.

[0045] As above, what this case protects is a handle dialing peach component and a lock body where the inside and outside door openings do not interfere with each other. All technical solutions that are the same as or similar to this case should be shown to fall within the protection scope of this case.
