Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to a reversible lock. Background Art

[0002] A linkage structure is usually provided between the handle peach and the anti-locking handle, lock tongue and other structures in the lock. The inner handle and outer handle in the door lock assembly are connected to the handle peach, so that the inner handle and outer handle are indirectly connected to the related structures in the lock, ultimately realizing functions such as unlocking, locking, anti-locking and releasing anti-locking.

[0003] At present, the inner handle and the outer handle in some door lock assemblies rotate independently of each other, so it is necessary to set two handle peaches connected to the inner handle and the outer handle respectively in the lock. Under this structural form, the above-mentioned linkage structure sometimes only needs to be linked with one of the handle peaches to achieve the corresponding function. However, the door leaf has two forms of left opening and right opening. Under these two different installation environments, one of the handle peaches will be on the inside and outside of the door respectively, and connected to the inner handle and the outer handle respectively. The linkage structure only needs to be indirectly connected to one of the handles, so it is necessary to move the linkage structure between the two handle peaches to ensure that the corresponding function can operate normally. That is, the lock needs to be reversing.

[0004] For example, a linkage structure related to the anti-locking function only needs to be linked with the handle lever connected to the outer handle to realize the anti-locking function. When the lock is installed on door leaves with different door opening directions, the linkage structure needs to be moved to make it linked with the handle lever connected to the outer handle.

[0033] Embodiment 1

[0034] In this embodiment, a reversible lock is disclosed, please refer to Figures 1a to 5The reversible lock comprises: a housing 11, a locking tongue slider 13, a first handle shifter 21, a second handle shifter 22, a reverse lock shifter 23 and a linkage block 14. The housing 11 can be formed by buckling two parts, and a space is formed in the middle to accommodate other components. Figure 1a and Figure 4 Only a half shell structure of the housing 11 is shown in the figure to show its internal structure. A bolt hole is provided on the side of the housing 11 for the bolt 12 to extend and retract to realize unlocking and locking.

[0035] The lock tongue slider 13 is slidably disposed in the housing 11, one end of which is connected to the lock tongue 12 and slides synchronously with the lock tongue 12, and an unlocking portion 131 is provided on the side away from the end of the lock tongue 12. The sliding assembly between the lock tongue slider 13 and the housing 11 and the sliding assembly between other structures in the following text can be realized by using structures such as slide grooves, slide rails, and slide rods in the prior art, and the details are not repeated here.

[0036] The first handle peach 21 and the second handle peach 22 are coaxially rotatable and arranged in the housing 11. When in use, they can be connected to the handle of the door, and the user can rotate the two handle peaches through the handle. The first handle peach 21 and the second handle peach 22 will face the inner and outer sides of the door leaf respectively during actual installation, and are respectively connected to the inner handle and the outer handle, and the user can rotate one of the handle peaches inside or outside the door. A first protrusion 31 is provided on the outer periphery of the first handle peach 21, and a second protrusion 32 is provided on the outer periphery of the second handle peach 22. The first protrusion 31 and the second protrusion 32 are both opposite to the unlocking portion 131. When the first handle peach 21 or the second handle peach 22 rotates to one side, the first protrusion 31 or the second protrusion 32 abuts on the unlocking portion 131 to drive the lock tongue slider 13 to move to the unlocking side, and then the lock tongue 12 is brought into the housing 11 to unlock.

[0037] like Figures 1a to 4 As shown, the unlocking portion 131 in this embodiment is a protruding structure located on the rotation path of the first protrusion 31 and the second protrusion 32. Figure 2a When the first handle peach 21 or the second handle peach 22 in the lock rotates clockwise, the side surface of the first protrusion 31 or the second protrusion 32 abuts against the unlocking portion 131, thereby pushing the lock tongue slider 13 to the unlocking side (i.e. Figure 2a Slide on the right side of the middle to unlock the door. Figure 1a and Figure 1b In other embodiments, the unlocking portion 131 may also be a recessed structure provided on the side of the lock tongue slider 13, as long as the first protrusion 31 or the second protrusion 32 can abut against the side thereof when rotating and drive the lock tongue slider 13 to slide toward the unlocking side.

[0038] The anti-locking peach 23 is rotatably disposed in the housing 11, and when in use, it can be connected to other structures such as the anti-locking knob on the door lock, and the user can rotate the anti-locking peach 23 by turning the anti-locking knob. An outwardly protruding sliding shaft 51 is formed on the anti-locking peach 23, which is used to link with the linkage block 14. The linkage block 14 is slidably disposed in the housing 11, and a sliding groove 52 is formed at one end thereof for the sliding of the sliding shaft 51, and the length direction of the sliding groove 52 is different from the sliding direction of the linkage block 14. Therefore, when the anti-locking peach 23 rotates, the sliding shaft 51 slides relatively in the sliding groove 52, which can drive the linkage block 14 to slide in the housing 11 according to a preset direction. When the linkage block 14 slides, the other end ( Figure 1a The right end of the door handle (in the middle) can slide to the side of the first handle paddle 21 or the second handle paddle 22, and correspondingly restrict the rotation of the first handle paddle 21 or the second handle paddle 22. At this time, the reversible lock is in an anti-locking state, that is, the user at least cannot rotate the handle on the outside of the door.

[0039] It should be noted that the linkage block 14 limits the rotation of the handle peach by surface contact. Figure 2a and Figure 3a As shown, the upper side of the linkage block 14 and the lower side of the first handle peach 21 can be in contact with each other. Figure 2a In the embodiment, the right end of the linkage block 14 is located on the left side of the axis of the first handle peach 21, and the first handle peach 21 can be rotated clockwise to unlock; Figure 3a In the embodiment, the right end of the linkage block 14 is located on the right side of the axis of the first handle peach 21. If the first handle peach 21 is rotated clockwise at this time, its lower side surface will be tightly against the upper surface of the linkage block 14, and it cannot continue to rotate or unlock.

[0040] In the reversible lock, if the rotation of the first handle peach 21 is not restricted by the locking block 14, the first handle peach 21 is Figure 2a When the first protrusion 31 rotates clockwise, the side surface of the first protrusion 31 abuts against the unlocking portion 131 and drives the lock tongue slider 13 to the unlocking side ( Figure 2a If the rotation of the second handle peach 22 is not restricted by the locking block 14, the second handle peach 22 is moved to Figure 2b When the second protrusion 32 rotates counterclockwise, the side surface of the second protrusion 32 abuts against the unlocking portion 131 and drives the lock tongue slider 13 to the unlocking side ( Figure 2b Slide the finger (center left) to unlock.

[0041] For the reversible lock in this embodiment, there are two handles, and the inner and outer handles do not share one handle. Therefore, the inner and outer handles can rotate independently. In actual installation, there are forms of door leaf opening on the left and right. Correspondingly, the first handle 21 in the reversible lock will be on the inside and outside of the door leaf in these two situations. In the reversible lock, only the handle that can be restricted by the linkage block 14 can be used to connect with the outer handle to achieve the anti-locking function. Therefore, in order to ensure that the reversible lock can be applied to both left-opening and right-opening door leaves, a reversing member 15 and an operating hole 16 are also provided in the housing 11 of the reversible lock. The user can adjust the connection position of the reversing member 15 and the linkage block 14 through the operating hole 16, so that the linkage block 14 slides on the side of the first handle 21 or the side of the second handle 22. Specifically, when the linkage block 14 is connected to the reversing member 15 at the first position, the linkage block 14 slides on the side of the first handle shift peach 21 to realize linkage with the first handle shift peach 21 to limit the rotation of the first handle shift peach 21; when the linkage block 14 is connected to the reversing member 15 at the second position, the linkage block 14 slides on the side of the second handle shift peach 22 to realize linkage with the second handle shift peach 22 to limit the rotation of the second handle shift peach 22. In this embodiment, the linkage block 14 and the reversing member 15 can be adjusted to be connected at the first position and the second position through the operating hole 16, so that the user can conveniently and quickly perform reversing operation on the lock in actual application.

[0042] For example, in this embodiment Figures 1a to 5 In the embodiment, the linkage block 14 is connected to the reversing member 15 at the first position. At this time, the linkage block 14 is set to slide on the side of the housing 11 close to the first handle peach 21. The linkage block 14 limits the first handle peach 21, and indirectly limits the outer handle connected thereto, thereby realizing the anti-locking function. Subsequently, if it is necessary to apply it to door leaves with different door opening directions, it is only necessary to adjust the connection position of the reversing member 15 and the linkage block 14 so that the two are connected at the second position, and the linkage block 14 can be set to slide on the side of the housing 11 close to the second handle peach 22. At this time, the second handle peach 22 can be connected to the outer handle to realize the limit of the outer handle, and the first handle peach 21 is close to the inner side of the door, which is used to connect to the inner handle, and can also complete the anti-locking.

[0043] In this embodiment, a specific form of the switching member 15 is also disclosed. Figure 5The reversing member 15 is a reversing screw threadedly connected to the linkage block 14, and the two ends of the reversing screw abut against the inner wall of the housing 11. The side wall of the housing 11 is formed with an operating hole 16 opposite to the end face of the reversing screw. First, the two ends of the reversing screw abut against the inner wall of the housing 11, and can slide synchronously with the linkage block 14 without affecting the relevant functions of the linkage block 14; secondly, when the user rotates the reversing screw through the operating hole 16, the linkage block 14 can also move along the axial direction of the reversing screw, so that the linkage block 14 and the reversing screw can be connected at the first position and the second position, thereby realizing the function of the linkage block 14 sliding on the side of the first handle 21 or the side of the second handle 22. In other words, the reversing operation of the lock can be completed only by rotating the reversing screw.

[0044] Since the reversing screw in this embodiment needs to slide synchronously with the linkage block 14 in the housing 11, the diameter of the operating hole 16 is set to be smaller than the diameter of the end face of the reversing screw, so as to prevent both ends of the reversing screw from entering the operating hole 16 and affecting the normal operation of the linkage block 14. In this structural form, the reversing operation can be performed only when the reversing screw slides with the linkage block 14 to face the operating hole 16.

[0045] In order to further improve the stability of the reversible lock, a limit groove is formed on the inner wall of the housing 11 in the same direction as the sliding direction of the linkage block 14, and the end of the reversing screw is slidably arranged in the limit groove. This ensures that the reversing screw and the linkage block 14 only move in a predetermined direction when in use, and no misalignment or other faults will occur.

[0046] The above linkage block 14 is arranged in the housing 11 in a sliding manner, and realizes linkage with the first handle peach 21 or the second handle peach 22. In another embodiment, the linkage block 14 can also be arranged in the housing 11 in a rotating manner, and realizes linkage with the first handle peach 21 or the second handle peach 22. For example, after the linkage block 14 rotates forward by a preset angle, one end abuts on the first handle peach 21 to limit the rotation of the first handle peach 21, and then reversely rotates by a preset angle to release the rotation restriction of the first handle peach 21. At this time, the linkage block 14 needs to be arranged in the housing 11 around the axial rotation of the reversing screw, and the end of the reversing screw is in the operating hole 16, which can prevent the reversing screw from moving. Under this structural form, the reversing screw can be rotated through the operating hole 16, and the linkage block 14 cannot rotate at a large angle in the housing 11, so it will move along the axial direction of the reversing screw, so that the linkage block 14 and the reversing screw are connected at the first position and the second position. It should be noted that although the linkage block 14 will move a certain distance in the axial direction when rotating the preset angle, it will not exceed the axial width of the first handle paddle 21 or the second handle paddle 22, and can only limit the rotation of one of the handle paddles.

[0047] In addition, in this embodiment, it is intended to provide a lock that can conveniently and quickly perform a reversing operation, and the reversing operation refers to adjusting one end of the linkage block 14 to be linked with the first handle peach 21 or the second handle peach 22. Which structure the other end of the linkage block 14 is linked with is irrelevant to the technical problem to be solved in this application. In the above embodiments, the other end of the linkage block 14 is linked with the anti-locking peach 23 only to illustrate the basic function of the lock and to supplement the effect of the reversing operation. In other embodiments, when the other end of the linkage block 14 is connected to other structures, the above-mentioned reversing operation can also be performed.

[0048] Embodiment 2

[0049] In this embodiment, another reversible lock is disclosed, which is different from the reversible lock in the first embodiment mainly in the structure of the reversing member 15 and the connection method with the linkage block 14. Other structures such as the lock tongue 12, the lock tongue slider 13, the linkage block 14, the first handle shift peach 21, the second handle shift peach 22, the reverse lock shift peach 23, etc. are the same as those in the first embodiment and are not described in detail here.

[0050] Please combine Figure 6 In this embodiment, the side wall of the housing 11 is provided with a first operating hole 161 and a second operating hole 162 opposite to each other. When the switching member 15 is arranged in the first operating hole 161 and the inner end abuts against the upper side wall of the linkage block 14, the linkage block 14 is connected to the switching member 15 at the first position. Figure 6 As shown, at this time, the linkage block 14 is slidably disposed on the lower side of the housing 11, and the left end slides on the side of the first handle paddle 21 to achieve linkage with the first handle paddle 21 to limit the rotation of the first handle paddle 21.

[0051] Similarly, when the reversing member 15 is taken out and installed in the second operating hole 162 so that its inner end abuts against the lower side wall of the linkage block 14, the linkage block 14 is connected to the reversing member 15 in the second position. At this time, the linkage block 14 is slidably arranged on the upper side of the housing 11, and the left end slides on the side of the second handle shift peach 22 to achieve linkage with the second handle shift peach 22 to limit the rotation of the second handle shift peach 22.

[0052] In this embodiment, by installing the reversing member 15 in the first operating hole 161 or the second operating hole 162, and using the inner end of the reversing member 15 to push the linkage block 14 to move in the shell, the linkage block 14 and the reversing member 15 can be connected at the first position and the second position, so that the user can easily and quickly perform reversing operations on the lock in actual applications.

[0053] Furthermore, in this embodiment, the reversing member 15 is a reversing screw that can be threadedly connected to the first operating hole 161 and the second operating hole 162. In practical applications, the reversing screw can be fixedly installed in the first operating hole 161 or the second operating hole 162 by rotating it, and the inner end abuts against a side wall of the linkage block 14. This further facilitates the user to perform the reversing operation. Of course, in other embodiments, interference connection, clamping, etc. can also be used to achieve the connection between the reversing member 15 and the first operating hole 161 and the second operating hole 162.

[0054] Similar to the first embodiment, in this embodiment, the linkage block 14 is slidably disposed in the housing 11, and a limiting groove having the same direction as the sliding direction of the linkage block 14 is formed on the side wall of the linkage block 14, and the inner end of the reversing member 15 is slidably disposed in the limiting groove. This ensures that the linkage block 14 moves only in a predetermined direction when in use, and does not cause misalignment or other faults, thereby further improving the stability of the reversible lock.

[0055] In another embodiment, the linkage block 14 can also be rotatably disposed in the housing 11, and a circular arc-shaped limiting groove is formed on the side wall of the linkage block 14, and the inner end of the reversing member 15 is slidably disposed in the limiting groove. It can also ensure that the linkage block 14 moves only in a predetermined direction when in use, and will not cause misalignment and other faults, further improving the stability of the reversible lock.

[0056] Embodiment 3

[0057] In this embodiment, another reversible lock is disclosed, which is different from the reversible lock in the first embodiment mainly in the structure of the reversing member 15 and the connection method with the linkage block 14. Other structures such as the lock tongue 12, the lock tongue slider 13, the linkage block 14, the first handle shift peach 21, the second handle shift peach 22, the reverse lock shift peach 23, etc. are the same as those in the first embodiment, and will not be repeated here.

[0058] Please combine Figure 7 and Figure 8 In this embodiment, an operating hole 16 is provided on the side wall of the housing 11 and is opposite to the linkage block 14. A first protrusion 41 is provided in the middle of the side of the linkage block 14. A second protrusion 42 is provided in the middle of the switching member 15 and is opposite to the first protrusion 41. The displacement of the switching member 15 in the depth direction of the operating hole 16 is limited. Figure 8 As shown in FIG. 1 , when the side surface of the first protrusion 41 abuts against the first side surface (left side surface) of the second protrusion 42, the linkage block 14 is connected to the reversing member 15 at the first position. At this time, one end of the linkage block 14 slides on the side of the first handle shift peach 21 to achieve linkage with the first handle shift peach 21 to limit the rotation of the first handle shift peach 21. When the linkage block 14 is pushed toward the first handle shift peach 21 through the operating hole 16, the linkage block 14 is moved to the first handle shift peach 21. Figure 8When moving to the right side, the first protrusion 41 slides along the second protrusion 42, and then the side surface of the first protrusion 41 abuts against the second side surface (right side surface) of the second protrusion 42. At this time, the linkage block 14 is connected to the reversing member 15 at the second position. Accordingly, one end of the linkage block 14 slides on the side of the first handle shift peach 21 to achieve linkage with the first handle shift peach 21 to limit the rotation of the first handle shift peach 21.

[0059] In this embodiment, the cross-sections of the first protrusion 41 and the second protrusion 42 are both arc-shaped, which can reduce the external force required to push the linkage block 14 to move, and further facilitate the user to perform the reversing operation.

[0060] Furthermore, in this embodiment, the reversing member 15 is a cylindrical structure sleeved on the linkage block 14, and its two sides abut against the inner wall of the housing 11. Therefore, during normal use of the lock, the reversing member 15 will not move along the depth direction of the operating hole 16, and indirectly fixes the linkage block 14 in this direction. Only when external force intervenes can the linkage block 14 move along this direction and achieve reversal.

[0061] A strip plate 151 is formed on one side wall of the switching member 15. Only two ends of the strip plate 151 are connected to the switching member 15 body. A gap is provided between the two sides of the strip plate 151 and the switching member 15 body. The middle part of the strip plate 151 is bent to one side to form the second protrusion 42. Figure 8 When moving in the left and right directions, the strip plate 151 can be deformed upward to a certain extent under the action of the first protrusion 41, which is conducive to the passage of the linkage block 14 and makes it easier for the user to complete the reversing operation.

[0062] Of course, in other embodiments, the switching member 15 can also be a structure fixed in the shell 11. As long as the above-mentioned second protrusion 42 is ensured to exist, the connection between the switching member 15 and the connecting block 14 at the first position and the second position can be achieved. The connecting block 14 is limited along the depth direction of the operating hole 16 by the cooperation of the second protrusion 42 and the inner wall of the shell 11.

[0063] Furthermore, in this embodiment, a guide groove 141 is formed on the side of the linkage block 14 along the depth direction of the operation hole 16, the first protrusion 41 is arranged in the guide groove 141, and the second protrusion 42 is arranged to slide relatively along the guide groove 141. This structure further limits the path of the relative movement of the switching member 15 and the linkage block 14, ensuring that the switching operation can operate stably.

[0064] Furthermore, in this embodiment, the side wall of the reversing member 15 is provided with a through hole 152 opposite to the operating hole 16. When performing the reversing operation, the user can use a tool to extend into the operating hole 16 and the through hole 152, abut against the side of the linkage block 14, and then push the linkage block 14 to move. In this structural form, the external force on the linkage block 14 is in the same direction as the slide slot, and it is not easy to have an obvious resistance torque, which is conducive to the smooth completion of the reversing operation.

[0065] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
