[0005] The handle is rotatably connected to the housing, the unlocking lock cylinder is disposed inside the handle, and the mortise lock assembly is movably disposed inside the handle and the housing, and the mortise lock assembly rotates synchronously with the handle;

[0006] The mortise lock assembly includes a mortise portion and has an inserted state and an unexposed state. The unlocking cylinder is used to insert an unlocking key and, when subjected to external force, drives the mortise lock assembly to switch between the inserted state and the unexposed state. In the inserted state, the mortise portion extends out of the housing and can be inserted into the latch unlocking structure of the door lock. The handle operates the latch unlocking structure through the mortise lock assembly and along the unlocking or locking direction. In the unexposed state, the mortise portion retracts from the latch unlocking structure, and the handle can rotate at any angle relative to the housing.

[0007] In some embodiments of this utility model, the handle mortise lock structure further includes a drive component disposed within the handle, and the unlocking lock cylinder drives the mortise lock component to move through the drive component.

[0008] In some embodiments of this utility model, the driving assembly includes an adapter and a driving member. The adapter is connected to the driving member and rotates synchronously. The adapter is also connected to the unlocking lock cylinder. The driving member is used to drive the mortise lock assembly to move linearly when rotating.

[0009] In some embodiments of this utility model, the driving member includes a driving part that extends along the circumferential direction of the driving member and is configured as an inclined structure; the mortise lock assembly includes a mating part that is in sliding contact with the driving part.

[0010] In some embodiments of this utility model, the mortise lock assembly includes a driven member and a first elastic member. The first elastic member is sleeved on the outer peripheral wall of the driven member, with one end abutting against the outer peripheral protrusion of the driven member and the other end abutting against the inner wall of the handle or the housing. The first elastic member is used to provide a restoring force for the driven member.

[0011] In some embodiments of this utility model, the driven member is provided with a limiting flange, and a limiting step is formed inside the handle. The limiting flange and the limiting step cooperate to limit the movement stroke of the driven member.

[0012] In some embodiments of this utility model, the handle is provided with a first limiting part, and the outer peripheral wall of the driven member is provided with a second limiting part, and the first limiting part and the second limiting part are mutually limiting.

[0013] In some embodiments of this utility model, the mortise lock assembly includes a driven member, a mortise member, a blocking member, and a second elastic member. The driven member is hollow, and the blocking member is disposed at one end of the driven member near the opening of the unlocking lock cylinder. One end of the mortise member is movably disposed inside the driven member, and the other end forms the mortise portion.

[0014] The second elastic member is disposed inside the driven member, with one end abutting against the sealing member and the other end abutting against the insert member. The insert member is provided with a limiting wall, and the driven member is provided with a stop wall. When the second elastic member is in the extended state, the limiting wall and the stop wall are in a limiting engagement, and the insert member moves with the driven member.

[0015] In some embodiments of this utility model, the outer peripheral wall of the insert is provided with a guide groove, the guide groove extends along the length direction of the insert, and the driven member is provided with a guide portion, the guide portion and the guide groove are guided and cooperated with each other;

[0016] The guide groove near the unlocking lock cylinder has a limiting wall formed on its groove wall, and the guide portion near the unlocking lock cylinder has a stop wall formed on its side wall.

[0017] In some embodiments of this utility model, the handle is provided with a receiving cavity with open ends, the housing is provided with a hollow cavity communicating with the receiving cavity, the unlocking lock cylinder is provided at the open end of the handle away from the housing, and part of the mortise lock assembly is provided in the receiving cavity and the other part is provided in the hollow cavity.

[0018] In some embodiments of this utility model, the handle is provided with a connecting end, the housing is provided with a mounting groove, and the connecting end is rotatably disposed in the mounting groove; the handle mortise lock structure further includes an anti-disengagement component, and the connecting end is connected to the groove wall of the mounting groove through the anti-disengagement component.

[0019] To achieve the above objectives, this utility model also proposes a door lock, which includes a bolt unlocking structure, a bolt structure, and a handle mortise lock structure. The handle mortise lock structure unlocks or locks the bolt structure through the bolt unlocking structure.

[0020] The beneficial effects of this utility model are as follows: Unlike the prior art, the handle mortise lock structure disclosed in this utility model is designed with a handle that can rotate freely. Even in the incorrect unlocking state, the handle can rotate freely. This design effectively prevents forced opening. Even when subjected to strong twisting, the free rotation of the handle can act as a force to be twisted, thereby avoiding strong damage. Moreover, unlocking does not require rotating the key. Instead, the handle is rotated while the key is inserted, which drives the mortise lock assembly to perform the locking and unlocking operation. This not only makes unlocking easier and helps extend the service life of the lock and key, but also provides a better operating feel, which can greatly improve the user experience.

[0034] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0038] This utility model proposes a handle-type insert lock structure, referring to... Figures 1 to 4 The handle mortise lock structure 30 includes a housing 1, a handle 2, an unlocking lock cylinder 3, and a mortise lock assembly 4. The handle 2 is rotatably connected to the housing 1, the unlocking lock cylinder 3 is disposed inside the handle 2, and the mortise lock assembly 4 is movably disposed inside the handle 2 and the housing 1, rotating synchronously with the handle 2.

[0039] The mortise lock assembly 4 includes a mortise portion 421 and has an inserted state and an uninserted state. In both the inserted and uninserted states, the handle 2 can rotate relative to the housing 1, allowing the unlocking cylinder 3 to be inserted for the unlocking key. When subjected to external force, the mortise lock assembly 4 is driven to switch between the inserted and uninserted states. In the inserted state, the mortise portion 421 extends out of the housing 1 and can be inserted into the latch unlocking structure 10 of the door lock 100. The handle 2 operates the latch unlocking structure 10 through the mortise lock assembly 4 and along the unlocking or locking direction. In the uninserted state, the mortise portion 421 is disengaged from the latch unlocking structure 10, and the handle 2 can rotate at any angle relative to the housing 1.

[0040] Based on the above design, handle 2 has a free-spinning function. In the case of incorrect unlocking, handle 2 can rotate freely. This design effectively prevents forced opening. Even when subjected to strong twisting, the free-spinning of handle 2 can act as a force to be twisted, thus avoiding strong damage. Moreover, unlocking does not require rotating the key. Instead, when the key is inserted, rotating handle 2 drives the mortise lock assembly 4 to perform the locking and unlocking operation. This not only makes unlocking easier and helps extend the service life of the lock and key, but also provides a better operating feel, which can greatly improve the user experience.

[0041] Understandably, when the unlocking key is not inserted, the handle 2 can rotate at any angle; after the unlocking key is inserted, before the mortise 421 is inserted into the latch unlocking structure 10, the handle 2 can also rotate at any angle, so that the handle 2 adaptively drives the mortise 421 to be inserted into the latch unlocking structure 10; after the mortise 421 is inserted into the latch unlocking structure 10, the handle 2 is rotated at a certain angle along the unlocking or locking direction, the rotation of the handle 2 drives the mortise 421 to rotate, the mortise 421 drives the latch unlocking structure 10 to unlock or lock, and then the unlocking key is rotated again, so that the mortise 421 is disengaged from the latch unlocking structure 10, and the handle 2 can rotate at any angle.

[0042] The direction in which the latch of the latch structure 20 extends is the locking direction, and the direction in which the latch of the latch structure 20 retracts is the unlocking direction.

[0043] The unlocking lock cylinder 3 is installed inside the handle 2 via a limiting pin. The handle 2 has a pin hole into which the limiting pin is inserted. Under the action of the limiting pin, the unlocking lock cylinder 3 can be stably installed on the handle 2, ensuring the structural stability of the handle-mounted lock structure 30. It is understood that the unlocking lock cylinder 3 has a lock cylinder hole exposed to the external space for the insertion of the unlocking key. The unlocking lock cylinder 3 can be a mechanical lock cylinder as used in existing technology, which will not be described in detail here.

[0044] Reference Figures 1 to 8 The handle mortise lock structure 30 also includes a drive assembly 5 disposed within the handle 2. The unlocking lock cylinder 3 drives the mortise lock assembly 4 to move via the drive assembly 5. The drive assembly 5 is disposed between the unlocking lock cylinder 3 and the mortise lock assembly 4. One end of the drive assembly 5 is connected to the rotating part of the unlocking lock cylinder 3, and the other end is in a transmission engagement with the mortise lock assembly 4.

[0045] The drive component 5 drives the mortise lock assembly 4 to move, so that the mortise part 421 of the mortise lock assembly 4 can be inserted into the latch unlocking structure 10 of the door lock 100. When the mortise part 421 is inserted into the latch unlocking structure 10, there is no need to continue rotating the unlocking key. Just operate the handle 2 to rotate, so that the handle 2 drives the mortise lock assembly 4 to rotate, thereby driving the latch unlocking block of the latch unlocking structure 10 to rotate, thereby operating the locking and unlocking of the door lock 100.

[0046] With this configuration, the handle 2 can rotate relative to the housing 1 whether the mortise 421 is inserted into the latch unlocking structure 10 or not. This allows the handle 2 to rotate freely, which effectively prevents the handle mortise lock structure 30 from being forcibly disassembled or from being forcibly twisted, thus effectively protecting the handle mortise lock structure 30.

[0047] The drive assembly 5 includes an adapter 51 and a drive component 52. The adapter 51 is connected to the drive component 52 and rotates synchronously. The adapter 51 is also connected to the unlocking lock cylinder 3. The drive component 52 is used to drive the mortise lock assembly 4 to move linearly when rotating.

[0048] The adapter 51 and the drive component 52 can be integrally formed or detachably connected. In the embodiment of this application, the adapter 51 and the drive component 52 are detachably connected. This configuration allows for the reasonable assembly and disassembly of the handle mortise lock structure 30 according to actual conditions.

[0049] The driving component 52 has a limiting hole 521 on the side facing the adapter 51. The limiting hole 521 can be set as a square hole, a rectangular hole, a polygonal hole, etc. The adapter 51 has a protrusion 511, which extends into the limiting hole 521. The protrusion 511 and the limiting hole 521 are matched in a limiting fit. The shape of the protrusion 511 is adapted to the limiting hole 521. The adapter 51 drives the driving component 52 to rotate through the protrusion 511.

[0050] The driving member 52 includes a driving part 522, which extends along the circumferential direction and is configured with an inclined structure. The mortise lock assembly 4 includes a mating part 411, with the driving part 522 in sliding contact with the mating part 411. This configuration, through the driving part 522 and the mating part 411, rationally utilizes the structural characteristics to convert the circumferential rotation of the driving member 52 into linear movement of the mortise lock assembly 4, thus enabling the conversion of movement modes within the limited space of the handle 2.

[0051] When the drive unit 522 is configured as an inclined structure, the drive unit 522 can be a gentle slope, which includes an inclined slope 5221 and a flat slope 5222. The connection between the inclined slope 5221 and the flat slope 5222 is rounded. When the inclined slope 5221 slides into contact with the mating part 411, the inclined slope 5221 gradually pushes the mating part 411 to move, so that the mortise lock assembly 4 moves linearly. When the mating part 411 slides from the inclined slope 5221 to the flat slope 5222, the drive unit 522 no longer pushes the mortise lock assembly 4 to move.

[0052] The number of driving parts 522 includes two, which are spaced apart along the circumferential direction of the driving member 52. Correspondingly, the number of mating parts 411 includes two, which are in one-to-one contact with the two driving parts 522. The mutual cooperation of the two driving parts 522 and the two mating parts 411 increases the pushing stability of the mortise lock assembly 4, enabling the mortise lock assembly 4 to move stably.

[0053] When the lock is unlocked, the operator inserts the unlocking key into the lock cylinder hole of the unlocking lock cylinder 3. The operator can rotate the key 90° clockwise, which unlocks the lock cylinder 3 and drives the drive assembly 5 to rotate. The drive part 522 pushes the mating part 411 to move, causing the mortise lock assembly 4 to move until the mortise part 421 is inserted into the latch unlocking structure 10. Then, the handle 2 is rotated counterclockwise, and the handle 2 drives the mortise lock assembly 4 to rotate synchronously, so that the mortise lock assembly 4 can move the latch unlocking block of the latch unlocking structure 10. The latch unlocking block causes the latch of the lock 100 to retract, thereby unlocking the lock.

[0054] When the lock is locked, the operator inserts the unlocking key into the lock cylinder hole of the unlocking lock cylinder 3. The operator can rotate the key 90° clockwise, which unlocks the lock cylinder 3 and drives the drive assembly 5 to rotate. The drive part 522 pushes the mating part 411 to move, causing the mortise lock assembly 4 to move until the mortise part 421 is inserted into the latch unlocking structure 10. Then, the operator rotates the handle 2 clockwise, which simultaneously drives the mortise lock assembly 4 to rotate synchronously, so that the mortise lock assembly 4 can move the latch unlocking block of the latch unlocking structure 10 until the latch unlocking block no longer moves. The latch unlocking block causes the latch of the lock 100 to extend. Finally, the operator rotates the key 90° counterclockwise, the mortise lock assembly 4 returns to its original position, and the mortise part 421 exits the latch unlocking structure 10, thus locking the lock.

[0055] When the unlocking key is not inserted into the unlocking cylinder 3, the insert part 421 does not contact the door latch unlocking structure 10, and rotating the handle 2 will not unlock the door.

[0056] Continue to refer to Figures 1 to 8The mortise lock assembly 4 includes a driven member 41 and a first elastic member 44. The first elastic member 44 is sleeved on the outer peripheral wall of the driven member 41, with one end abutting against the outer peripheral protrusion of the driven member 41 and the other end abutting against the inner wall of the handle 2 or the housing 1. The first elastic member 44 is used to provide a restoring force for the driven member 41.

[0057] With this configuration, after the handle 2 moves the mortise lock assembly 4 and completes the unlocking or locking, the first elastic element 44 not only enables the driven element 41 to return to its original position smoothly, but also enables the driven element 41 to drive the mortise part 421 to exit the latch unlocking structure 10. The handle 2 will not unlock or lock if it rotates at any angle.

[0058] The driven member 41 can be configured as a driven shaft, which is a stepped shaft with a hollow center. A protrusion is formed on the end face of the driven shaft facing the unlocking lock cylinder 3, forming a mating part 411. The first elastic member 44 can be configured as a spring or other structural member with elastic properties, which is not limited here.

[0059] The driven member 41 is provided with a limiting flange 412, and a limiting step 22 is formed inside the handle 2. The limiting flange 412 and the limiting step 22 engage to limit the movement stroke of the driven member 41. By cooperating with each other, the limiting flange 412 and the limiting step 22 can confine the driven member 41 inside the handle 2, ensuring the structural connection between the handle 2 and the mortise lock assembly 4, and effectively avoiding the possibility of structural failure due to structural connection detachment.

[0060] The handle 2 is provided with a first limiting part 23, and the outer peripheral wall of the driven member 41 is provided with a second limiting part 413. The first limiting part 23 and the second limiting part 413 are engaged in a limiting cooperation. Through the first limiting part 23 and the second limiting part 413, the handle 2 and the driven member 41 are rotated synchronously, thereby driving the mortise lock assembly 4 to move as a whole.

[0061] The first limiting part 23 and the second limiting part 413 can both be set as planes, and the planes form a limit; the first limiting part 23 and the second limiting part 413 are connected or inserted into each other, such as the first limiting part 23 being a locking block and the second limiting part 413 being a locking groove, with the locking block and the locking groove engaging.

[0062] Continue to refer to Figures 1 to 8The mortise lock assembly 4 includes a driven member 41, a mortise member 42, a blocking member 43, and a second elastic member 45. The driven member 41 is hollow. The blocking member 43 is located at the open end of the driven member 41 near the unlocking cylinder 3. One end of the mortise member 42 is movably disposed within the driven member 41, and the other end forms a mortise portion 421. The second elastic member 45 is disposed within the driven member 41, with one end abutting against the blocking member 43 and the other end abutting against the mortise member 42. The mortise member 42 is provided with a limiting wall 4221, and the driven member 41 is provided with a stop wall 4141. When the second elastic member 45 is in an extended state, the limiting wall 4221 and the stop wall 4141 engage in a limiting cooperation, and the mortise member 42 moves with the driven member 41.

[0063] With this configuration, when the drive unit 522 pushes the driven member 41 to move, the driven member 41 drives the insert member 42 to move through the sealing member 43 and the second elastic member 45 during the movement, so as to realize that the driven member 41 drives the insert member 42 to move synchronously. Through the limiting wall 4221 and the stop wall 4141 limiting cooperation, the insert member 42 can be restricted within the driven member 41 to prevent the insert member 42 from detaching from the driven member 41. Through the second elastic member 45, the insert member 42 can also be elastically inserted into the door latch unlocking structure 10, increasing the stability of the insert part 421 inserted into the door latch unlocking structure 10, so that the handle 2 can drive the door latch unlocking structure 10 more stably, thereby further improving the user's operating feel.

[0064] Understandably, both the sealing member 43 and the insert member 42 are provided with grooves for the two ends of the second elastic member 45 to be installed. The grooves can limit the ends of the second elastic member 45, thus ensuring stable and reliable installation of the second elastic member 45. The sealing member 43 can be configured as a plug or a column head. The sealing member 43 is embedded in the opening of the driven member 41, and the sealing member 43 is interference-fitted with the driven member 41 to fix it on the driven member 41.

[0065] The mortise portion 421 is formed at the end of the mortise member 42 away from the unlocking cylinder 3. The mortise portion 421 is rectangular, square, polygonal, or similar in shape. The side of the mortise portion 421 also has a protrusion. After the mortise portion 421 is inserted into the door latch unlocking structure 10, the handle 2 rotates the mortise portion 421. The protrusion prevents the mortise portion 421 from disengaging from the door latch unlocking structure 10, so that the handle 2 can stably control the door latch unlocking structure 10 through the mortise portion 421.

[0066] The outer peripheral wall of the mortise cylinder 42 is provided with a guide groove 422, which extends along the length of the mortise cylinder 42. The driven member 41 is provided with a guide portion 414, which guides and engages with the guide groove 422. A limit wall 4221 is formed on the groove wall of the guide groove 422 near the end of the unlocking lock cylinder 3, and a stop wall 4141 is formed on the side wall of the guide portion 414 near the end of the unlocking lock cylinder 3.

[0067] With this configuration, the guide part 414 and the guide groove 422 guide each other, allowing the follower 41 and the insert 42 to move in a mutually guiding manner, thereby increasing the stability of the movement of the follower 41 and the insert 42.

[0068] Continue to refer to Figures 1 to 8 The handle 2 has a receiving cavity 21 with open ends, the housing 1 has a hollow cavity communicating with the receiving cavity 21, the unlocking lock cylinder 3 is located at the open end of the handle 2 away from the housing 1, part of the mortise lock assembly 4 is located in the receiving cavity 21, and the other part is located in the hollow cavity.

[0069] The handle 2 has an operating part 24, which can be cylindrical, spherical, square, or similar in shape. In this embodiment, the operating part 24 is cylindrical. A threaded structure is formed on the surface of the operating part 24, which increases surface friction and improves the operator's feel.

[0070] The handle 2 is provided with a connecting end 25, and the housing 1 is provided with a mounting groove 11. The connecting end 25 is rotatably disposed in the mounting groove 11. The handle mortise lock structure 30 also includes an anti-disengagement component 6, and the connecting end 25 is connected to the groove wall of the mounting groove 11 through the anti-disengagement component 6.

[0071] Specifically, the outer peripheral wall of the connecting end 25 has an outer ring groove 251, the groove wall of the mounting groove 11 has an inner ring groove 12, and the anti-detachment component 6 is disposed in the outer ring groove 251 and the inner ring groove 12, so as to realize that the handle 2 can be detached from the housing 1. The anti-detachment component 6 can be configured as a retaining ring.

[0072] This utility model also proposes a door lock, referring to... Figure 9 and Figure 10 The door lock 100 includes a bolt unlocking structure 10, a bolt structure 20, and a handle mortise lock structure 30. The handle mortise lock structure 30 unlocks or locks the bolt structure 20 through the bolt unlocking structure 10.

[0073] The latch structure 20 has a contoured hole 201. The handle mortise lock structure 30 is located on one side of the contoured hole 201, and the latch unlocking structure 10 is located on the other side of the contoured hole 201. The handle mortise lock structure 30 is fixedly connected to the latch unlocking structure 10 by screws. The latch unlocking structure 10 has a groove 101, which corresponds to the mortise part 421. The mortise part 421 can be inserted into or withdrawn from the groove 101.

[0074] Both the latch structure 20 and the latch unlocking structure 10 can adopt the existing latch structure 20, which will not be described in detail here. The specific structure of the handle mortise lock structure 30 is the same as that in the above embodiments. Since the door lock 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0075] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
