Description

Technical Field

[0001] The invention relates to the field of locks, and in particular to a lock handle mounting structure, a lock using the mounting structure, and an anti-theft door having the lock. Background Art

[0002] The modular design and production of the product can effectively reduce the storage, logistics and use costs of the product. For example, during use, when a module is damaged and fails, the module can be removed, replaced and repaired, and other modules can continue to be used. In this way, it is necessary to set up an installation structure that can be quickly disassembled and assembled between each module. In particular, for users who are not professional maintenance personnel, they can also simply disassemble and assemble each module through such a quick installation structure, and the problems faced can be solved without the need for professional maintenance personnel to be on site. In addition, the manufacturing cost of the handle assembly with built-in smart components is relatively high, while the cost of the lock assembly is relatively low. In response to the requirements of door thicknesses of different specifications, it is only necessary to prepare lock assemblies of multiple specifications, which can be assembled into a complete set of locks with internal and external handle assemblies to reduce inventory costs.

[0003] One prior art for modularly installing a lock head and a handle is CN208122531U, which discloses that modular handle assemblies are installed at both ends of a lock core (i.e., a lock head), and the thumbwheel on the lock head is driven by rotating the handle assembly to drive the bolt mechanism on the door lock to move. The portion of the first rotating shaft on the lock head that protrudes from the end of the lock head and acts as a lock core shaft constitutes an insertion portion, and the handle assembly is provided with a fastening hole that cooperates with the insertion portion and a threaded hole that is not parallel to the first rotating shaft, and a top screw is screwed into the threaded hole. The handle assembly is installed on the lock head through the insertion portion and the fastening hole, and the relative position between the handle assembly and the first rotating shaft can be locked by tightening the top screw. Loosening the top screw can release the locking form so that the outer handle assembly can slide along the first rotating shaft. Through the above structure, during installation, the handle assembly is installed on the lock head through the insertion portion, and through the cooperation of the top screw and the fastening hole insertion portion, such a structure allows the handle assembly to be easily loaded and unloaded on the lock head.

[0004] However, in the above technical solution, the locking and positioning is performed only by the top screw screwed on the handle assembly. Due to factors such as vibration during use, the screw connection may become loose and the stability is relatively poor. In addition, the top screw, which is a locking component, is also the object of action of an actuating tool such as a screwdriver. In order for the actuating tool to operate the top screw, it is necessary to appropriately expose the part of the top screw suitable for the action of the screwdriver. Such application requirements require either leaving a release gap between the handle assembly and the door leaf surface for the tool to operate, or opening a hole on the circumferential surface of the handle for the top screw to pass through. Whether leaving a gap or opening a hole on the circumferential surface, it will have a negative impact on the appearance of the handle assembly. In particular, when opening a hole on the circumferential surface, the degree of tightening of the top screw is different, resulting in a feeling of protrusion or defect when holding the handle during use. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the handle installation structure in the prior art that the locking positioning stability between the handle and the lock head is poor, and then provide a handle installation structure that can make the handle and the lock head convenient to install and safe and stable.

[0006] Another technical problem to be solved by the present invention is to overcome the defect of the handle installation structure in the prior art lock that leads to poor locking and positioning stability between the handle and the lock head, and thus provide a lock that can make the handle and the lock head easy to install and safe and stable.

[0007] Another technical problem to be solved by the present invention is to overcome the defect of the handle installation structure of the anti-theft door in the prior art that the locking positioning stability between the handle and the lock is poor, and thus provide an anti-theft door that can make the handle and the lock head both convenient to install and safe and stable.

[0008] To this end, the technical solution provided by the present invention is as follows:

[0009] A lock handle installation structure, comprising:

[0010] The protrusion is arranged on the inner and outer ends of the main lock head having the lock sleeve and the transmission member rotatably mounted in the lock sleeve, and extends toward the handle;

[0011] A concave cavity is formed on the handle, faces the end of the main lock when installed, and is plugged with the protruding portion to limit the non-axial movement between the handle and the main lock; the concave cavity has a non-circular connection structure that is plugged with the transmission member in the main lock;

[0012] Also includes:

[0013] A locking structure, disposed between the protrusion and the concave cavity, adapted to achieve axial fixation between the protrusion and the concave cavity;

[0014] The actuating mechanism is arranged on the handle and is suitable for driving the locking structure to switch between a locked state and an unlocked state. The movement direction of the force-applying component in the actuating mechanism for driving to the locked state forms an angle with the movement direction of the force-bearing component on the locking structure in the locked state.

[0015] As a preferred technical solution, the locking structure includes:

[0016] A locking member, driven by the actuating mechanism and movably installed in the handle between a locking position and a releasing position, wherein a moving direction forms an angle with a plugging direction of the protrusion and the cavity;

[0017] The locking groove is arranged on the protruding portion and is suitable for allowing the end of the locking member close to the protruding portion to be embedded therein in the locking position.

[0018] As a preferred technical solution, the locking member is slidably disposed in a slideway formed in the handle.

[0019] As a preferred technical solution, the actuating mechanism includes:

[0020] a biasing member, disposed between the locking member and the handle, for applying a biasing force on the locking member in a direction away from the protrusion; and

[0021] A force applying member for driving the locking member toward the locking state is movably arranged in the handle in a direction forming an angle with the moving direction of the locking member.

[0022] As a preferred technical solution, one of the interaction parts of the force-applying member and the locking member or both of them are provided with a pushing inclined surface. When the force-applying member pushes the locking member from one of the release position and the locking position to the other, the pushing inclined surface gradually protrudes toward the other side, so as to overcome the biasing force of the biasing member and push the locking member to move.

[0023] As a preferred technical solution, the force-applying member is an actuating member fixedly connected to a rotating member, and the rotating member is rotatably installed in a handle; the rotating member has a manual operation structure.

[0024] As a preferred technical solution, the rotation axis of the actuating member is parallel to the sliding direction of the locking member.

[0025] As a preferred technical solution, the rotating member is one of the secondary lock core shaft of the secondary lock head fixedly mounted on the handle or the secondary lock sleeve, and the other of the two serves as the rotating member and is fixedly connected to the actuating member.

[0026] As a preferred technical solution, the force-applying member is arranged on a channel in the handle.

[0027] As a preferred technical solution, the channel extends from the end of the handle facing the main lock head when the handle is installed along the axial direction of rotation of the handle.

[0028] As a preferred technical solution, the channel is a screw hole, the force-applying member is an actuating screw threadably installed in the screw hole, and the push inclined surface is a conical surface formed on the top end of the actuating screw.

[0029] As a preferred technical solution, the protrusion is in a tubular shape extending from the locking sleeve, and the locking groove is in a circular ring shape arranged on the outer wall of the protrusion.

[0030] A lock having the lock handle installation structure described in the above technical solution.

[0031] A theft-proof door comprises the above-mentioned lock.

[0032] The technical effects of the above technical solution are:

[0033] 1. The lock handle installation structure provided in the present invention includes a protrusion, a cavity, a locking structure and an actuating structure. The protrusion is arranged on the inner and outer ends of the main lock having a lock sleeve and a transmission member rotatably installed in the lock sleeve, and extends toward the handle; the cavity is formed on the handle, facing the end of the main lock when installed, and plugging and cooperating with the protrusion to limit the non-axial movement between the handle and the main lock; the cavity has a non-circular connection structure that is mutually plugged with the transmission member in the main lock; the locking structure is arranged between the protrusion and the cavity, and is suitable for completing axial fixation between the protrusion and the cavity; the actuating mechanism is arranged on the handle, and is suitable for driving the locking structure to switch between the locked state and the unlocked state, and the movement direction of the force-applying member in the actuating mechanism for driving to the locked state forms an angle with the movement direction of the force-bearing member on the locking structure in the locked state.

[0034] In the above structure, the handle and the main lock can be quickly plugged in by means of the protrusions respectively arranged on the main lock and the concave cavity arranged on the handle, so that the handle and the main lock can be installed in a modular manner. The actuating structure arranged on the handle can drive the locking structure to perform locking and unlocking actions, so that axial movement between the handle and the main lock can be avoided. Moreover, more importantly, when the handle and the main lock have a tendency to move relative to each other due to factors such as vibration, the movement tendency will directly affect the locking structure and be stopped by the locking structure. Since the locking structure and the actuating structure are in a matching relationship, the movement tendency will not be directly transmitted to the actuating structure. Therefore, the above structure can effectively reduce the interference of factors such as vibration on the locking structure, make the positioning between the main lock and the handle more stable, avoid the locking structure from becoming loose, and greatly improve the safety and stability of the entire handle installation structure.

[0035] 2. In the lock handle installation structure provided in the present invention, the locking structure includes a locking member and a locking groove. The locking member is driven by the actuating mechanism and is movably installed in the handle between a locking position and a release position, and its moving direction forms an angle with the insertion direction of the protrusion and the concave cavity; the locking groove is arranged on the protrusion and is suitable for allowing one end of the locking member close to the protrusion to be embedded therein in the locking position.

[0036] On the one hand, the above structure provides a simpler and easier to implement structural basis for the locking structure; on the other hand, by adopting a matching method of a movable locking piece and a locking groove, when the locking piece vibrates between the handle and the main lock head, the vibration can be more easily converted into the vibration of the locking piece itself, thereby minimizing the impact on the actuating structure, ensuring that the actuating structure can more stably maintain the locking state of the locking piece, and further improving the installation stability between the handle and the main lock head.

[0037] 3. In the lock handle installation structure provided in the present invention, the locking member is slidably disposed in a slideway formed in the handle.

[0038] In the above structure, the method of installing the locking element in the handle through the slide has the following effects: first, compared with the method of setting the locking element separately, it can reduce the number of modules of the lock, making the disassembly and assembly of the handle more convenient; second, compared with the method of setting the locking element on the main lock, on the one hand, it is conducive to reducing the complexity of the main lock, and is conducive to making main locks of different lengths according to different door thicknesses; on the other hand, since the actuating structure is set on the handle, it is also more conducive to using a simple structure to achieve the coordination of the locking element and the actuating structure.

[0039] 4. In the lock handle installation structure provided in the present invention, the manual operating end includes an auxiliary lock, and one of the lock core shaft of the auxiliary lock or the lock sleeve is fixedly installed on the handle, and the other of the two serves as the rotating member and is fixedly connected to the actuator.

[0040] By setting the manual operating end of the locking member to the shape of a secondary lock head, the rotation operation of the actuator can only be completed with the cooperation of a key. When there is no special key, the actuator will be locked, and the locking member will also maintain a locked state or an unlocked state under the action of the actuator or the biasing member. Therefore, this can further improve the anti-theft performance of the entire installation structure.

[0041] 5. In the lock handle installation structure provided in the present invention, the actuator is arranged on the channel inside the handle.

[0042] Compared with the actuating member installed by rotation through the auxiliary lock head, this type of actuating member installed in the handle channel has better concealment and is more suitable for being arranged on the inner handle.

[0043] 6. In the lock handle installation structure provided in the present invention, the protruding portion is a tubular shape extending from the lock sleeve, and the locking groove is a circular ring shape arranged on the outer wall of the protruding portion.

[0044] In the above structure, the annular locking groove can be engaged with the locking member in the entire circumference of the locking groove, which means that the entire handle has more angles when cooperating with the protrusion of the main lock, thereby effectively reducing the difficulty of installing the handle and the main lock; at the same time, the tubular lock sleeve can provide more installation space for the main lock, so that parts such as wires can be conveniently passed through the main lock to connect the inner and outer handles, thereby improving the compactness and rationality of the structure of the entire lock. It also has a better effect than using the transmission member as the protrusion connection, that is, the transmission member is completely hidden in the cover formed by the lock sleeve and the handle, and the transmission member cannot be contacted from the outside, making the structure of the lock more difficult to be destroyed. The transmission member here can be either a lock core connected to the outer handle or a transmission shaft connected to the inner handle.

[0045] 7. The lock provided by the present invention has the above-mentioned lock handle installation structure, and thus also has the advantages brought by the above-mentioned lock handle installation structure.

[0046] 8. The anti-theft door provided by the present invention includes the above-mentioned lock, and thus also has all the advantages brought by the above-mentioned lock.

[0047] To sum up, the lock handle installation structure, lock and anti-theft door provided by the present invention have the advantage of being more stable when the lock and the handle are installed, and also have the advantages of good anti-theft performance, simple assembly of the handle and the lock, and compact and reasonable structure.

DETAILED DESCRIPTION

[0059] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0061] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] A concept that needs to be explained in advance is that all the outer sides, inner sides, upper edges, lower edges, etc. mentioned in the following embodiments are based on the posture of the mask when worn on the human body. The upper edge is close to the bridge of the nose, the lower edge is close to the chin, the outer side is the side away from the skin, and the inner side is the side close to the skin.

[0064] See also Figure 1 , Figure 2 and Figure 3, is an embodiment of the present invention, and this embodiment provides a lock handle installation structure, comprising a main lock 3 composed of a main lock sleeve 1 and a main lock core shaft 2 rotatably installed in the main lock sleeve 1 as a transmission member, and a handle 4 suitable for being installed on the main lock 3. The end of the lock sleeve of the main lock 3 corresponds to the handle 4, and the tubular protrusion protruding toward the handle 4 forms a protrusion 5, and the end of the handle 4 connected to the main lock 3 is formed with a cavity 6. The cavity 6 has a non-circular connection structure that is mutually plugged with the main lock core shaft 2 in the main lock 3. The handle 4 can be conveniently installed on the main lock 3 through the cooperation of the cavity 6 and the protrusion 5.

[0065] The locking mechanism 7 for axially locking the handle 4 on the protruding portion 5 comprises an annular locking groove 8 formed on the outer circumferential surface of the tubular protruding portion of the protruding portion 5 and a locking member 10 slidably arranged in a slideway 9 formed on the handle 4. The extending direction of the slideway 9 forms an angle with the plug-in direction of the protruding portion 5 and the cavity 6, so as to allow the locking member 10 to reciprocate between a locking position where it is inserted into the locking groove 8 and a release position where it is removed from the locking groove 8. The locking member 10 achieves locking of the handle 4 and the main lock 3 when inserted into the locking groove 8, and unlocks the handle 4 and the main lock 3 when removed from the locking groove 8.

[0066] The handle 4 is also provided with a spring 11 as a biasing member between the locking member 10 and the handle 4, which tends to drive the locking member 10 in the locking mechanism 7 to move to a release position out of the locking groove 8, and an actuating member 12 as a force-applying member provided on the handle 4 for driving the locking member 10 to move toward a locking position embedded in the locking groove 8 to overcome the biasing force of the spring 11. The actuating member 12 is fixedly connected to a secondary lock core shaft 14 of a secondary lock head 13 as a rotating member, a secondary lock sleeve 15 of the secondary lock head 13 is fixedly installed in the handle 4, the secondary lock core shaft 14 is rotatably installed in the secondary lock sleeve 15, and the rotation axis of the secondary lock core shaft 14 is parallel to the sliding direction of the locking member 10. The secondary lock core shaft 14 has a keyhole suitable for inserting a key 16 as a manual operation structure. The interaction portion between the locking member 10 and the actuating member 12 is a slope 17 which gradually protrudes toward the actuating member 12 and serves as a push slope. When the actuating member 12 rotates from the release position to the lock position, the push slope can overcome the biasing force of the spring 11 to push the locking member 10 from the release position to the lock position, and can also gradually release the push on the locking member 10 from the lock position, so that the locking member 10 moves from the lock position to the release position under the biasing force of the spring 11. In this embodiment, the rotation plane of the actuating member 12 is perpendicular to the sliding direction of the locking member 10.

[0067] During installation, the concave cavity 6 on the handle 4 is aligned with the protrusion 5 on the main lock 3 and plugged into each other, so that the locking groove 8 on the protrusion 5 is aligned with the slideway 9 on the handle 4 on which the locking member 10 is installed. The key 16 is inserted into the keyhole on the secondary lock core shaft 14 in the secondary lock 13, so that the secondary lock 13 is unlocked, and then the secondary lock 13 is rotated to drive the actuator 12 fixed thereon to rotate. During the rotation process, the slope 17 of the interaction portion between the locking member 10 and the actuator 12 is used to drive the locking member 10 to move toward the annular locking groove 8, and the biasing force of the spring 11 is overcome during the movement process, and the spring 11 is stored with energy. When the actuator 12 rotates to a state where the locking member 10 is embedded in the locking groove 8, the locking between the handle 4 and the main lock 3 is completed.

[0068] During use, since the locking member 10 is embedded in the annular locking groove 8, the axial displacement of the handle 4 relative to the main lock 3 is limited, so that the handle 4 cannot be removed from the main lock 3. When the handle 4 is rotated, the locking member 10 can slide and rotate in the embedded annular locking groove 8, meeting the rotation requirement of the handle 4. This structure in which the handle 4 is connected to the protruding portion 5 of the tubular protrusion of the main lock sleeve 1 has a better effect, that is, the transmission member is completely hidden in the housing formed by the lock sleeve and the handle 4, and the transmission member cannot be contacted from the outside, making the structure of the lock more difficult to be damaged.

[0069] When the handle 4 needs to be removed from the main lock 3, the key 16 is inserted into the keyhole on the secondary lock core shaft 14 in the secondary lock 13, so that the secondary lock 13 is unlocked, and then the secondary lock 13 is rotated in the opposite direction of the above operation, so that the secondary lock 13 drives the actuator 12 fixed thereon to rotate. During the rotation process, the slope 17 of the interaction portion between the actuator 12 and the locking member 10 gradually loses the push on the locking member 10, and under the action of the biasing force of the spring 11, the locking member 10 is moved out of the annular locking groove 8 until it is completely disengaged. At this time, the handle 4 is pulled out axially relative to the main lock 3 to complete the disassembly.

[0070] In the above embodiment, the spring 11 as the biasing member and the locking member 10 can also be arranged in the following manner. That is, the spring 11 is arranged between the main lock sleeve 1 and the locking member 10, but the biasing force of the spring 11 is used to maintain the locking member 10 in the locked position, and the ramp surface 17 as the push inclined surface on the locking member 10 is arranged in the opposite direction to the ramp surface 17 in the above embodiment. In this way, when the unlocking handle 4 and the main lock head 3 need to be locked axially, the actuator 12 is rotated, and the actuator 12 uses the ramp surface 17 to pull the locking member 10 to the unlocking position, and overcomes the biasing force of the spring 11 during the pulling process. When the handle 4 and the main lock head 3 need to be locked axially, the actuator 12 is rotated in the opposite direction to release the obstruction of the ramp surface 17 by the actuator 12. In this way, under the biasing force of the spring 11, the locking member 10 moves toward the annular locking groove 8 on the main lock head 3 until it is embedded in the locking groove 8 to complete the locking action.

[0071] In the above embodiment, the rotating member fixing the actuating member 12 can be replaced by the secondary lock sleeve 15 of the secondary lock head 13, and the secondary lock core shaft 14 is fixedly mounted on the handle 4. In this way, the actuating member 12 can rotate around the main lock core shaft 2 in the secondary lock head 13. At this time, a handle is provided on the secondary lock sleeve 15, which exposes the handle 4, as the manual operation structure. During operation, when the key 16 is inserted into the keyhole on the secondary lock core shaft 14 to unlock the secondary lock head 13, the handle is then turned to rotate the secondary lock sleeve 15 to drive the actuating member 12 to rotate.

[0072] In the above embodiment, the protrusion 5 can be replaced by an outer end portion of the transmission member protruding from the main lock sleeve 1. The transmission member can be the main lock spindle 2 or the transmission core 19 driving the thumbwheel 18. In this case, the locking groove 8 can be replaced by a concave point corresponding to the slideway 9 on which the locking member 10 is installed.

[0073] See also Figure 4 and Figure 5 , which is another embodiment of the present invention. This embodiment also provides a lock handle installation structure having the same Figure 1 -3 shows the same locking structure as the embodiment shown in FIG. The difference is that the force-applying member is an actuating screw 20, and the actuating screw 20 is threadedly installed in a screw hole 21 as a passage provided in the handle 4. The screw hole 21 extends from the end of the handle 4 facing the main lock head 3 when the handle 4 is installed along the axial direction of the rotation of the handle 4, and the push-up inclined surface is a conical surface 22 formed at the top of the actuating screw 20.

[0074] When in use, the actuating screw 20 is rotated to make the actuating screw 20 reciprocate in the screw hole, and then the locking member 10 is driven by the conical surface 22 .

[0075] Since the actuating structure in this embodiment adopts a threaded structure, it can be operated using a tool such as a screwdriver or a wrench. Therefore, the installation structure of the lock handle 4 in this embodiment is more suitable for application on the inner handle 4b.

[0076] See also Figure 6 , Figure 7 and Figure 8 This embodiment provides a lock having a Figure 1 -3 The outer handle 4a installed in the lock handle installation structure in the embodiment shown in FIG. Figure 4 , 5 The inner handle 4b is installed in the lock handle installation structure in the illustrated embodiment.

[0077] When in use, the inner handle 4b is first sleeved on the main lock 3, and the actuating screw 20 is screwed in, so that the locking member 10 overcomes the biasing force of the inner spring 11b in the inner handle 4b and is lifted up, and is inserted into the locking groove 8 on the protruding portion 5 on the inner side of the main lock 3 to achieve locking. Then, the main lock 3 with the inner handle 4b is installed on the door lock in a common manner and fixed to the door lock. Then, the outer handle 4a is sleeved on the protruding portion 5 of the main lock 3 extending out of the door, and the key 16 is inserted into the keyhole of the auxiliary lock 13 in a matching manner, so that the auxiliary lock core shaft 14 with the actuating member 12 can rotate relatively, thereby driving the actuating member 12 to rotate and transmitting it to the locking member 10 in a pushing manner, so that the locking member 10 overcomes the biasing force applied by the outer spring 11a in the outer handle 4a and moves, and is stuck in the locking groove 8 on the protruding portion 5 of the main lock 3, thereby locking the outer handle 4a.

[0078] The disassembly process is the reverse process described above, which will not be described in detail here. In this embodiment, the inner handle 4b is assembled and disassembled by screwing in and out, and the outer handle is assembled and disassembled using a key 16, which is convenient and safe.

[0079] As a more preferred embodiment, the key 16 opening structure of the main lock 3 and the auxiliary lock 13 can be set to the same structure. In this way, one key 16 can be used to open and lock the main and auxiliary locks, saving one key 16 and simplifying the operation of the actuating structure.

[0080] The above two embodiments of the lock handle mounting structure and the one embodiment of the lock can be generally applied to anti-theft doors. Therefore, the anti-theft door is also an embodiment provided by the present invention. The use of the anti-theft door with the above lock handle mounting structure or lock is the same as the use of the anti-theft door under normal circumstances, and will not be repeated here.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
