Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically, to a quick-reversing door lock handle. Background Technology

[0002] Door locks are a frequently used device in daily life. During the installation process, the handle is matched to the opening direction of the door. However, in actual installation, there is a problem of the handle being installed in the wrong direction. In this case, the handle needs to be removed and the direction adjusted for reinstallation. This usually requires a special screwdriver or disassembling the front and back panels of the door lock to change the handle direction, which is complicated and time-consuming.

[0003] Therefore, improving the ease of reversing door lock handles is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides a quick-reversing door lock handle, which can improve the convenience of reversing the door lock handle and save the time of reversing the door lock handle.

[0005] This application is achieved through the following technical solution: This application provides a quick-reversing door lock handle, which includes a handle, a lock cylinder assembly, a transition fixing block, and a reversing locking assembly. The handle is circumferentially rotatable relative to the transition fixing block. The handle has a first mounting space, and the transition fixing block has a second mounting space. The first and second mounting spaces combine to form a receiving cavity for installing the reversing locking assembly. The reversing locking assembly has a first position where the handle is circumferentially fixed to the transition fixing block, achieving a transmission connection, and a second position where the handle is circumferentially unlocked from the transition fixing block, achieving a transmission separation. The handle has a reversing hole that allows the reversing locking assembly to be switched from the first position to the second position by a tool. The lock cylinder assembly has an unlocked state and a locked state. When the lock cylinder assembly is in the locked state, it limits and fixes the reversing locking assembly in the first position, restricting the handle's reversing. When the lock cylinder assembly is in the unlocked state, it releases the limitation on the reversing locking assembly, allowing the reversing locking assembly to switch from the first position to the second position, and the handle can rotate circumferentially relative to the transition fixing block to complete left and right reversing.

[0006] The technical solution of this application embodiment achieves the transmission connection and transmission separation between the handle and the adapter fixing block by setting a reversing locking component. The reversing hole allows the reversing locking component to be switched from a first position to a second position using a tool, which improves the convenience of handle reversing and saves time. Simultaneously, when the lock cylinder assembly is in the locked state, the limiting reversing locking component is in the first position, ensuring that handle reversing can only be performed after unlocking, thus improving the security of the door lock handle.

[0007] In some embodiments, the reversing locking assembly includes a reversing locking block and an elastic member. The reversing locking block is radially movably disposed in a second mounting space along the transition fixing block. One end of the elastic member is connected to the inner wall of the second mounting space, and the other end abuts against the reversing locking block. In the first position, the handle and the transition fixing block rotate synchronously, the first mounting space and the second mounting space are aligned and connected, and the elastic member elastically pushes the reversing locking block to move, so that part of the reversing locking block is located in the first mounting space and another part is located in the second mounting space, thereby achieving a transmission lock between the handle and the transition fixing block. In the second position, the handle rotates circumferentially relative to the transition fixing block, the first mounting space and the second mounting space are misaligned circumferentially in the transition fixing block, the reversing locking block exits the first mounting space and compresses the elastic member, thereby achieving a transmission separation between the handle and the transition fixing block.

[0008] The technical solution of this application embodiment, by setting a reversing locking block and an elastic member, so that the elastic member abuts between the reversing locking block and the inner wall of the second installation space, is conducive to improving the convenience of moving the reversing locking assembly from the second position to the first position.

[0009] In some embodiments, there are two second mounting spaces, which are arranged symmetrically along the radial direction of the transition fixing block. Each second mounting space is provided with a set of reversing locking components. In the first position, the first mounting space and one of the second mounting spaces form a receiving cavity. One set of reversing locking components in the receiving cavity is driven to lock the handle, and the other set of reversing locking components is used to drive to lock the handle after reversing, thereby realizing bidirectional reversing of the handle.

[0010] The technical solution of this application embodiment, by setting two second installation spaces to cooperate with the first installation space, enables the reversing locking component to move from the first first position through the second position to the second first position, which is beneficial to improving the convenience of handle reversing and saving the time of door lock handle reversing.

[0011] In some embodiments, the lock cylinder assembly includes a lock cylinder and a lock cylinder connecting shaft. The lock cylinder connecting shaft connects the lock cylinder and a transition fixing block. The lock cylinder connecting shaft has a first limiting portion that protrudes axially from the end face of the lock cylinder connecting shaft facing the transition fixing block. The end face of the reversing locking block facing the lock cylinder connecting shaft has a second limiting portion that matches the first limiting portion. In the locked state, at least a portion of the first limiting portion is located radially on the side of the second limiting portion away from the reversing hole of the transition fixing block to prevent the reversing locking block from exiting the first mounting space. In the unlocked state, the first limiting portion and the second limiting portion are misaligned circumferentially on the transition fixing block to allow the reversing locking block to exit radially from the first mounting space.

[0012] The technical solution of this application embodiment, by setting a first limiting part and a second limiting part to cooperate, allows the handle to be changed only after unlocking, which helps to improve the security of the door lock handle.

[0013] In some embodiments, the first limiting portion includes a first segment and a second segment. The first segment extends radially along the transition fixing block, and the second segment extends axially along the transition fixing block. The first segment connects the lock cylinder connecting shaft and the second segment, and the second segment protrudes from the end face of the lock cylinder connecting shaft facing the transition fixing block. There are two first limiting portions and two reversing locking blocks. The two reversing locking blocks are arranged radially opposite to each other along the transition fixing block. In the locked state, radially along the transition fixing block, the second segment of one first limiting portion is located on the side of the second limiting portion opposite to the reversing hole, and the other second limiting portion is located between the second segment of the other first limiting portion and the lock cylinder connecting shaft to stop the reversing locking block.

[0014] The technical solution of this application embodiment, by setting a first segment and a second segment, in the locked state, the second segment of a first limiting part is located on the side of a second limiting part away from the reversing hole, and the other second limiting part is located between the second segment of another first limiting part and the lock cylinder connecting shaft. That is, the second segment of a first limiting part limits the reversing locking assembly to the first position, and reduces the risk of interference between the other first limiting part and the second limiting part, which is beneficial to improving the reliability of the door lock handle.

[0015] In some embodiments, the handle has a receiving space, a transition fixing block is disposed in the receiving space, a first mounting space is disposed on the inner peripheral surface of the handle, a second mounting space is disposed on the outer peripheral surface of the transition fixing block, and the door lock handle also includes a handle bearing, the handle bearing is sleeved on the transition fixing block and connected to the inner peripheral surface of the handle.

[0016] The technical solution of this application embodiment, by setting a handle bearing to connect the adapter fixing block, allows the adapter fixing block to rotate relative to the handle, which helps to improve the convenience and reliability of unlocking.

[0017] In some embodiments, the door lock handle further includes a first retaining ring, and the wall forming the receiving space is provided with a first mounting groove. The first retaining ring is disposed in the first mounting groove and is tightly fitted with the end face of the handle bearing away from the lock cylinder assembly, thereby achieving axial positioning and anti-disengagement of the handle bearing.

[0018] The technical solution of this application embodiment, by setting a first retaining ring to limit the handle bearing, is beneficial to improving the reliability of handle bearing installation.

[0019] In some embodiments, the door lock handle further includes a washer disposed between the first retaining ring and the adapter retaining block.

[0020] The technical solution of this application embodiment reduces the risk of interference between the first retaining ring and the transition fixing block by setting a washer ring between the first retaining ring and the transition fixing block, which helps to improve the reliability of the door lock handle.

[0021] In some embodiments, the door lock handle further includes a second retaining ring. The outer peripheral surface of the adapter fixing block is provided with a second mounting groove. The second retaining ring is snapped and fixed inside the second mounting groove. The outer end face of the second retaining ring is tightly fitted with the end face of the handle bearing facing the lock cylinder assembly. It cooperates with the first retaining ring to achieve bidirectional axial positioning of both ends of the handle bearing.

[0022] The technical solution of this application embodiment, by setting a second retaining ring to limit the handle bearing, is beneficial to improving the reliability of handle bearing installation.

[0023] In some embodiments, the door lock handle further includes a seal, which is fitted onto the outer peripheral surface of the adapter fixing block to seal the gap between the adapter fixing block and the door panel.

[0024] The technical solution of this application embodiment reduces the risk of impurities entering the door lock handle by setting a sealing element to block the gap between the adapter fixing block and the door panel, which is beneficial to improving the reliability of the door lock handle.

[0035] Please refer to Figures 1 to 3 , Figure 1 This is an exploded view of the structure of a door lock handle provided in some embodiments of this application. Figure 2 This is an exploded view of the structure of a door lock handle provided in some embodiments of this application from another perspective. Figure 3 This is a schematic diagram of the internal structure of a door lock handle provided in some embodiments of this application. This application provides a quick-reversing door lock handle 1, which includes a handle 10, a lock cylinder assembly 20, a transition fixing block 30, and a reversing locking assembly 40. The handle 10 is circumferentially rotatable relative to the transition fixing block 30. The handle 10 is provided with a first mounting space 11, and the transition fixing block 30 is provided with a second mounting space 31. The first mounting space 11 and the second mounting space 31 combine to form a receiving cavity for mounting the reversing locking assembly 40. The reversing locking assembly 40 has a first position where the handle 10 is circumferentially fixed to the transition fixing block 30, achieving a transmission connection, and a second position where the handle 10 is circumferentially unlocked from the transition fixing block 30, achieving transmission separation. The handle 10 is provided with a reversing hole 12 that allows the reversing locking assembly 40 to be switched from the first position to the second position by a tool. The lock cylinder assembly 20 has an unlocked state and a locked state. When the lock cylinder assembly 20 is in the locked state, the lock cylinder assembly 20 limits the reversing locking component 40 to be fixed in the first position, restricting the handle 10 from reversing. When the lock cylinder assembly 20 is in the unlocked state, the lock cylinder assembly 20 releases the limitation on the reversing locking component 40, allowing the reversing locking component 40 to switch from the first position to the second position, and the handle 10 can rotate circumferentially relative to the transfer fixing block 30 to complete the left and right reversing.

[0036] The handle 10 may include a main body 10b and a handle portion 10a, with the handle portion 10a connected to the main body 10b. The main body 10b is connected to the door panel 2, which is typically rotatably mounted on a pivot to open and close the door. The handle portion 10a is typically positioned horizontally towards the pivot. However, during installation, the handle 10 may be installed backwards, causing the handle portion 10a to be positioned away from the pivot. In this case, the handle 10 needs to be reversed so that the handle portion 10a points towards the pivot to conform to the user's usage habits.

[0037] In some embodiments, the handle 10 is provided with a first mounting space 11, which can be integrally formed with the handle 10, or it can be formed by machining after the handle 10 is manufactured.

[0038] In some embodiments, the adapter fixing block 30 is provided with a second mounting space 31. The second mounting space 31 can be integrally formed with the adapter fixing block 30, or it can be formed by machining after the adapter fixing block 30 is manufactured.

[0039] In some embodiments, the adapter fixing block 30 may be disposed inside the handle 10. The first mounting space 11 of the handle 10 and the second mounting space 31 of the adapter fixing block 30 may communicate to form a receiving cavity for mounting the reversing locking assembly 40.

[0040] In some embodiments, the adapter fixing block 30 can be connected to the handle connecting shaft 3, thereby driving the handle connecting shaft 3 to rotate, thereby driving the lock body inside the door to unlock.

[0041] In some embodiments, the handle 10 is provided with a reversing hole 12, which can be integrally formed with the handle 10, or formed by machining after the handle 10 is manufactured.

[0042] In some embodiments, the reversing locking assembly 40 has a first position and a second position. In the first position, a portion of the reversing locking assembly 40 is located in the first mounting space 11, and another portion is located in the second mounting space 31, such that the handle 10 and the transition fixing block 30 are kinetically connected. That is, the door lock handle 10 is in normal use; rotating the handle 10 can drive the transition fixing block 30 to rotate, thereby unlocking the door. In the second position, the reversing locking assembly 40 can be located in either the first mounting space 11 or the second mounting space 31, such that the handle 10 and the transition fixing block 30 are kinetically separated. That is, the handle 10 can rotate relative to the transition fixing block 30, thereby reversing the direction of the handle 10. During reversal, a tool, such as a screwdriver or a pin, can be used to push the reversing locking assembly 40 from the first position to the second position, and rotating the handle 10 will reversal the direction of the handle 10.

[0043] It should be noted that the first mounting space 11 and the second mounting space 31 form a first receiving cavity, and the reversing locking assembly 40 is located in the first receiving cavity. When reversing, the handle 10 rotates relative to the adapter fixing block 30. After rotating 180 degrees, the first mounting space 11 and the second mounting space 31 form a second receiving cavity, and the reversing locking assembly 40 moves into the second receiving cavity.

[0044] In some embodiments, the lock cylinder assembly 20 has an unlocked state and a locked state. When the lock cylinder assembly 20 is in the locked state, it limits the reversing locking component 40 to a first position. When the lock cylinder assembly 20 is in the unlocked state, it allows the reversing locking component 40 to switch from the first position to a second position. That is, when the handle 10 is reversed, the lock cylinder assembly 20 needs to be unlocked to prevent other personnel from arbitrarily reversing the handle 10.

[0045] The technical solution of this application embodiment achieves the transmission connection and transmission separation between the handle 10 and the adapter fixing block 30 by setting a reversing locking component 40. The reversing hole 12 allows the reversing locking component 40 to be pushed from a first position to a second position using a tool, which improves the convenience of reversing the handle 10 and saves time in reversing the door lock handle 1. Simultaneously, when the lock cylinder assembly 20 is in the locked state, the limiting reversing locking component 40 is in the first position, ensuring that the handle 10 can only be reversed after unlocking, thus improving the security of the door lock handle 1.

[0046] Please refer to Figures 1 to 3 In some embodiments, the reversing locking assembly 40 includes a reversing locking block 41 and an elastic member 42. The reversing locking block 41 is radially movably disposed in the second mounting space 31 along the transition fixing block 30. One end of the elastic member 42 is connected to the inner wall of the second mounting space 31, and the other end abuts against the reversing locking block 41. In the first position, the handle 10 and the transition fixing block 30 rotate synchronously, the first mounting space 11 and the second mounting space 31 are aligned and connected, and the elastic member 42 elastically pushes the reversing locking block 41 to move, so that part of the reversing locking block 41 is located in the first mounting space 11 and the other part is located in the second mounting space 31, thereby realizing the transmission locking of the handle 10 and the transition fixing block 30. In the second position, the handle 10 rotates circumferentially relative to the adapter fixing block 30, and the first mounting space 11 and the second mounting space 31 are misaligned circumferentially on the adapter fixing block 30. The reversing locking block 41 exits the first mounting space 11 and compresses the elastic element 42, thereby realizing the transmission separation of the handle 10 and the adapter fixing block 30.

[0047] In some embodiments, the reversing locking block 41 is movably disposed in the second mounting space 31, and the elastic member 42 abuts against the inner wall of the reversing locking block 41 and the second mounting space 31. The elastic member 42 may be a spring.

[0048] In some embodiments, in the first position, the first mounting space 11 and the second mounting space 31 are aligned and connected to form a receiving cavity. The elastic element 42 is in its normal state, with a portion of the reversing locking block 41 located in the first mounting space 11 and the other portion located in the second mounting space 31. During reversal, the reversing locking block 41 is pushed out of the first mounting space 11 using a tool, the elastic element 42 stores force, and the handle 10 is rotated until the first mounting space 11 and the second mounting space 31 are realigned and connected. The restoring force of the elastic element 42 pushes a portion of the reversing locking block 41 into the first mounting space 11, thus linking the handle 10 and the adapter fixing block 30.

[0049] The technical solution of this application embodiment, by setting a reversing locking block 41 and an elastic member 42, so that the elastic member 42 abuts against the inner wall of the reversing locking block 41 and the second installation space 31, is beneficial to improving the convenience of moving the reversing locking assembly 40 from the second position to the first position.

[0050] Please refer to Figures 1 to 3 In some embodiments, there are two second mounting spaces 31, which are symmetrically arranged along the radial direction X of the transition fixing block. Each second mounting space 31 is provided with a set of reversing locking components 40. In the first position, the first mounting space 11 and one of the second mounting spaces 31 form a receiving cavity. One set of reversing locking components 40 in the receiving cavity is driven and locked with the handle 10, and the other set of reversing locking components is used to drive and lock with the handle after reversing, so as to realize the left and right bidirectional reversing of the handle.

[0051] In some embodiments, the radial direction X of the adapter fixing block can be represented by the direction indicated by the letter X in the figure, and the axial direction Y of the adapter fixing block can be represented by the direction indicated by the letter Y in the figure.

[0052] In some embodiments, the number of second mounting spaces 31 can be two, and each second mounting space 31 is provided with a reversing locking component 40, while the number of first mounting spaces 11 can be one.

[0053] In the first position, the first second mounting space 31 corresponds to the first mounting space 11, and the first reversing locking assembly 40 connects the first second mounting space 31 to the first mounting space 11, realizing the linkage between the handle 10 and the adapter fixing block 30. The second reversing locking assembly 40 is located in the second second mounting space 31, the elastic element 42 of the second reversing locking assembly 40 is compressed, and the reversing locking block 41 of the second reversing locking assembly 40 is located in the second second mounting space 31 and abuts against the inner wall of the handle 10.

[0054] During reversing, the first reversing locking assembly 40 is moved from the first mounting space 11 to the first second mounting space 31 using a tool. The handle 10 is rotated relative to the adapter fixing block 30 until the second second mounting space 31 aligns with the first mounting space 11. The second reversing locking assembly 40 then connects the second second mounting space 31 with the first mounting space 11, achieving linkage between the handle 10 and the adapter fixing block 30. The first reversing locking assembly 40 is located in the first second mounting space 31, the elastic element 42 of the first reversing locking assembly 40 is compressed, and the reversing locking block 41 of the first reversing locking assembly 40 is located in the first second mounting space 31 and abuts against the inner wall of the handle 10.

[0055] The technical solution of this application embodiment, by setting two second installation spaces 31 to cooperate with the first installation space 11, enables the reversing locking component 40 to move from the first first position through the second position to the second first position, which is beneficial to improving the convenience of reversing the handle 10 and saving the time of reversing the door lock handle 1.

[0056] Please refer to Figures 1 to 3 In some embodiments, there are two first mounting spaces 11, which are arranged opposite each other along the radial direction X of the adapter fixing block. In the first position, the second mounting space 31 and one of the first mounting spaces 11 form a receiving cavity.

[0057] In some embodiments, the number of first mounting spaces 11 can be two, the number of second mounting spaces 31 can be one, and the reversing locking assembly 40 is disposed in the second mounting space 31.

[0058] In the first position, the first mounting space 11 corresponds to the second mounting space 31, and the reversing locking assembly 40 connects the first mounting space 11 to the second mounting space 31 to achieve linkage between the handle 10 and the adapter fixing block 30.

[0059] During reversing, the reversing locking assembly 40 is moved from the first first mounting space 11 to the second mounting space 31 using a tool. The handle 10 is rotated so that it rotates relative to the adapter fixing block 30 until the second mounting space 31 corresponds to the second first mounting space 11. The reversing locking assembly 40 connects the second first mounting space 11 with the second mounting space 31, realizing the linkage between the handle 10 and the adapter fixing block 30.

[0060] It should be noted that there can be two first installation spaces 11 and two second installation spaces 31, and each second installation space 31 is provided with a reversing locking component 40.

[0061] In the first position, a second mounting space 31 corresponds to a first mounting space 11, and each reversing locking component 40 connects the second mounting space 31 to the first mounting space 11 to realize the linkage between the handle 10 and the adapter fixing block 30.

[0062] The number of reversing holes 12 can be two. When reversing, each reversing locking component 40 is moved from the first mounting space 11 to the second mounting space 31 by a tool, so that the handle 10 rotates relative to the adapter fixing block 30 until the first mounting space 11 and the second mounting space 31 are aligned again. The reversing locking component 40 connects the second mounting space 31 with the first mounting space 11, so as to realize the linkage between the handle 10 and the adapter fixing block 30.

[0063] The technical solution of this application embodiment, by setting two first installation spaces 11 and a second installation space 31 to cooperate, enables the reversing locking component 40 to move from a first first position through a second position to a second first position, which is beneficial to improving the convenience of reversing the handle 10 and saving the time of reversing the door lock handle 1.

[0064] Please refer to Figures 1 to 3 and refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram illustrating the cooperation between the reversing locking block and the lock cylinder connecting shaft according to some embodiments of this application. Figure 5 This is a schematic diagram of the structure of the reversing locking block and the lock cylinder connecting shaft provided in some embodiments of this application. In some embodiments, the lock cylinder assembly 20 includes a lock cylinder 21 and a lock cylinder connecting shaft 22. The lock cylinder connecting shaft 22 connects the lock cylinder 21 and the adapter fixing block 30. The lock cylinder connecting shaft 22 is provided with a first limiting part 221, which protrudes along the axial direction Y of the adapter fixing block from the end face of the lock cylinder connecting shaft 22 facing the adapter fixing block 30. The reversing locking block 41 is provided with a second limiting part 411 on the end face of the lock cylinder connecting shaft 22 that matches the first limiting part 221. In the locked state, at least a portion of the first limiting part 221 is located on the side of the second limiting part 411 away from the reversing hole 12 in the radial X direction of the adapter fixing block, so as to prevent the reversing locking block 41 from exiting the first mounting space 11; in the unlocked state, the first limiting part 221 and the second limiting part 411 are misaligned in the circumferential direction of the adapter fixing block 30, so as to allow the reversing locking block 41 to exit the first mounting space 11 radially.

[0065] In some embodiments, the lock cylinder 21 and the lock cylinder connecting shaft 22 are connected, and the connection method can be welding, bolting, etc.

[0066] In some embodiments, the lock cylinder connecting shaft 22 and the adapter fixing block 30 are connected by welding, bolting, or other methods.

[0067] In some embodiments, when the lock cylinder 21 is unlocked, the lock cylinder connecting shaft 22 drives the adapter fixing block 30 to rotate, and the adapter fixing block 30 drives the handle 10 connecting shaft to rotate, thereby achieving unlocking.

[0068] In some embodiments, the lock cylinder connecting shaft 22 is provided with a first limiting part 221. The first limiting part 221 can be integrally formed with the lock cylinder connecting shaft 22, or it can be formed by machining after the lock cylinder connecting shaft 22 is processed.

[0069] In some embodiments, the reversing locking block 41 is provided with a second limiting part 411. The second limiting part 411 can be integrally formed with the reversing locking block 41, or it can be formed by machining after the reversing locking block 41 is manufactured.

[0070] In some embodiments, the reversing hole 12 can communicate with the first mounting space 11, and the reversing hole 12, the first mounting space 11 and the second mounting space 31 are arranged sequentially along the radial direction X of the adapter fixing block.

[0071] In some embodiments, in the locked state, at least a portion of the first limiting portion 221 may be located on the side of the second limiting portion 411 opposite to the reversing hole 12. When the reversing locking block 41 is driven by a tool, the first limiting portion 221 abuts against the second limiting portion 411, preventing the reversing locking block 41 from leaving the first mounting space 11. In the unlocked state, the lock cylinder 21 drives the lock cylinder connecting shaft 22 to rotate, thereby causing the first limiting portion 221 and the second limiting portion 411 to be misaligned in the circumferential direction of the transition fixing block 30. When the reversing locking block 41 is driven by a tool, the reversing locking block 41 leaves the first mounting space 11.

[0072] The technical solution of this application embodiment, by setting the first limiting part 221 and the second limiting part 411 to cooperate, allows the handle 10 to be reversed only after unlocking, which helps to improve the security of the door lock handle 1.

[0073] Please refer to Figures 1 to 5In some embodiments, the first limiting portion 221 includes a first segment 2211 and a second segment 2212. The first segment 2211 extends radially X along the transition fixing block, and the second segment 2212 extends axially Y along the transition fixing block. The first segment 2211 connects the lock cylinder connecting shaft 22 and the second segment 2212. The second segment 2212 protrudes from the end face of the lock cylinder connecting shaft 22 facing the transition fixing block 30. There are two first limiting portions 221 and two reversing locking blocks 41. The two reversing locking blocks 41 are arranged opposite each other along the radial X of the transition fixing block. In the locked state, on the radial X of the transition fixing block, the second segment 2212 of one first limiting portion 221 is located on the side of one second limiting portion 411 away from the reversing hole 12, and the other second limiting portion 411 is located between the second segment 2212 of the other first limiting portion 221 and the lock cylinder connecting shaft 22 to stop the reversing locking block 41.

[0074] In some embodiments, the first segment 2211 and the second segment 2212 can be integrally formed. Along the radial X of the adapter fixing block, one end of the first segment 2211 is connected to the outer peripheral surface of the lock cylinder connecting shaft 22, and the other end is connected to the second segment 2212. Along the radial X of the adapter fixing block, one end of the second segment 2212 is connected to the first segment 2211.

[0075] In some embodiments, there are two first limiting portions 221 and two reversing locking blocks 41. In the locked state, the first reversing locking assembly 40 is connected to the first mounting space 11 and the second mounting space 31. The elastic element 42 of the first reversing locking assembly 40 is in the normal state. A portion of the reversing locking block 41 of the first reversing locking assembly 40 is located in the first mounting space 11, and another portion is located in the second mounting space 31, such that the second limiting portion 411 of the reversing locking block 41 of the first reversing locking assembly 40 is located on the side of the second segment 2212 of the first limiting portion 221 facing the reversing hole 12. The first limiting portion prevents the first reversing locking assembly 40 from moving from the first position to the second position. It is understandable that the second reversing locking assembly 40 is located in the second mounting space 31, that is, the elastic element 42 of the second reversing locking assembly 40 is in a compressed state, and the reversing locking block 41 of the second reversing locking assembly 40 is located in the second mounting space 31, that is, the second limiting part 411 of the reversing locking block 41 of the second reversing locking assembly 40 is located on the side opposite to the reversing hole 12 of the second segment 2212 of the second first limiting part 2211. Due to the existence of the first segment 2211, clearance space is provided for the second limiting part 411 of the reversing locking block 41 of the second reversing locking assembly 40, reducing the risk of interference between the second limiting part 411 of the reversing locking block 41 of the second reversing locking assembly 40 and the second first limiting part 221.

[0076] The technical solution of this application embodiment, by setting a first segment 2211 and a second segment 2212, in the locked state, the second segment 2212 of a first limiting part 221 is located on the side of a second limiting part 411 away from the reversing hole 12, and the other second limiting part 411 is located between the second segment 2212 of the other first limiting part 221 and the lock cylinder connecting shaft 22. That is, the second segment 2212 of a first limiting part 221 limits the reversing locking assembly 40 to the first position, and reduces the risk of interference between the other first limiting part 221 and the second limiting part 411, which is beneficial to improving the reliability of the door lock handle 1.
