Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, specifically relating to a lock body with a clutch structure. Background Technology

[0002] A lock body with a clutch mechanism is a lock system that adds a clutch device to a traditional mechanical lock. It is usually used in situations where high security and convenience are required. The core feature of this type of lock body is that it contains a clutch mechanism that controls the connection between the bolt or lock tongue and the operating mechanism, such as the key or handle.

[0003] In existing technologies, traditional lock bodies with clutch structures typically rely on correct unlocking operations to activate or deactivate the clutch state. The newly added latching mechanism provides an instant-response protection method that can automatically take defensive measures when abnormal behavior is detected, thereby enhancing the overall system reliability. Utility Model Content

[0004] The purpose of this invention is to provide a lock body with a clutch structure, which aims to solve the problem that traditional lock bodies with clutch structures in the prior art usually rely on the correct unlocking operation to activate or deactivate the clutch state.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lock body with a clutch mechanism, characterized in that it comprises:

[0007] case;

[0008] An emergency locking mechanism is provided inside a housing. The emergency locking mechanism includes a square shaft, a connector, locking elements, springs, and fixing elements. The square shaft is fixedly connected inside the housing. The connector is fixedly connected to the circumferential surface of the square shaft. Two locking elements are slidably connected to both ends of the connector. Two springs are fixedly connected to one end of each of the two locking elements. The fixing elements are fixedly connected to one end of each of the two springs.

[0009] A control mechanism, which is located inside the housing.

[0010] As a preferred embodiment of this utility model, the control mechanism includes a rack, a limiting slider, a drive shaft, and gears. The two racks are fixedly connected to the lower ends of the two locking members, the two limiting sliders are slidably connected inside the housing, the two limiting sliders are fixedly connected to one end of the two racks, the two drive shafts are rotatably connected inside the housing, and two gears are fixedly connected to the circumferential surfaces of the two drive shafts. The racks and gears mesh with each other.

[0011] As a preferred embodiment of this utility model, a clutch assembly is fixedly connected inside the housing.

[0012] In a preferred embodiment of this utility model, a push rod is slidably connected inside the clutch assembly, and one end of the push rod is fixedly connected to a connector.

[0013] As a preferred embodiment of this utility model, the docking device has a docking groove, and a connector is slidably connected in the docking groove.

[0014] As a preferred embodiment of this utility model, one end of the square shaft is fixedly connected to a handle, and two limiting grooves are opened in the housing, with two limiting sliders slidably connected in each of the two limiting grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] I. In this design, the locking element expands outward under mechanical thrust and engages with the limiting structure within the housing, preventing the square shaft from continuing to drive the bolt action, thus achieving a physical disconnection function. Only after the control mechanism is triggered will the locking element compress the spring and retract inward, disengaging from the limiting area, releasing the transmission path, and allowing the square shaft to transmit rotational motion to the bolt to complete the unlocking action. This design, through the linkage between the locking element, the connector, and the spring, automatically locks the transmission path in an unauthorized state, effectively preventing forced opening and improving the safety and stability of the lock.

[0017] II. In this solution, the limiting slider, which serves as the driving connection component for the movement of the locking element, cooperates with the internal sliding groove of the housing to ensure that the rack can only move smoothly in the set direction, avoiding deviation or jamming. The drive shaft is installed inside the housing, and two gears are fixedly connected to its outer circumference. The gears and rack maintain a meshing state, forming a stable transmission relationship. When the drive shaft rotates, it drives the gears to rotate, thereby driving the rack to make linear motion, further driving the locking element to slide in the docking device, realizing the switching of the clutch state. This structure efficiently converts rotational motion into linear motion through the meshing between the gears and rack, making the locking element's action more precise and the response faster, thus improving the overall lock body's operational stability and control accuracy.

[0025] Example

[0026] Please see Figures 1-4 The present invention provides the following technical solution:

[0027] A lock body with a clutch mechanism, comprising:

[0028] Casing 1;

[0029] An emergency locking mechanism is located inside the housing 1. The emergency locking mechanism includes a square shaft 2, a connector 3, locking elements 4, springs 5, and fixing elements 6. The square shaft 2 is fixedly connected inside the housing 1. The connector 3 is fixedly connected to the circumferential surface of the square shaft 2. The two locking elements 4 are slidably connected to both ends of the connector 3. The two springs 5 ​​are fixedly connected to one end of the two locking elements 4. The fixing elements 6 are fixedly connected to one end of the two springs 5.

[0030] The control mechanism is located inside the housing 1.

[0031] In a specific embodiment of this utility model, the lock body structure uses the housing 1 as a basic support platform, and an emergency locking mechanism is set inside. This mechanism mainly includes a square shaft 2, a connector 3, locking elements 4, a spring 5, and a fixing element 6. The square shaft 2, as a power input component, is fixed inside the housing 1 to receive the rotational motion transmitted by the external handle. The connector 3 is fastened to the outer circumference of the square shaft 2 and rotates synchronously with it. The two locking elements 4 are slidably installed in the guide grooves at both ends of the connector 3 and are connected to the fixing element 6 via the spring 5, forming an elastic reset structure. When the user operates the handle to rotate the square shaft 2... If the unlocking verification is not performed correctly, the locking element 4 expands outward under the action of mechanical thrust and gets stuck in the limiting structure inside the housing 1, preventing the square shaft 2 from continuing to drive the bolt action, thus achieving the physical disconnection function. Only after the control mechanism is triggered will the locking element 4 compress the spring 5 and retract inward, disengaging from the limiting area, releasing the transmission path, and allowing the square shaft 2 to transmit rotational motion to the bolt to complete the unlocking action. This design, through the linkage between the locking element 4, the docking device 3, and the spring 5, automatically locks the transmission path in the unauthorized state, effectively preventing forced opening and improving the safety and stability of the lock.

[0032] Please refer to the details. Figures 1-4 The control mechanism includes a rack 7, a limit slider 8, a drive shaft 9, and a gear 10. The two racks 7 are fixedly connected to the lower ends of the two locking parts 4. The two limit sliders 8 are slidably connected inside the housing 1. The two limit sliders 8 are fixedly connected to one end of the two racks 7. The two drive shafts 9 are rotatably connected inside the housing 1. The circumferential surfaces of the two drive shafts 9 are fixedly connected to two gears 10, and the racks 7 and gears 10 mesh with each other.

[0033] In this embodiment: the rack 7 is fixed below the locking member 4, serving as the driving connection component for the movement of the locking member. The limiting slider 8 cooperates with the internal sliding groove of the housing 1 to ensure that the rack 7 can only move smoothly in the set direction, avoiding deviation or jamming. The drive shaft 9 is installed inside the housing 1, and two gears 10 are fixedly connected on its outer circumference. The gears 10 and the rack 7 are in a meshing state, forming a stable transmission relationship. When the drive shaft 9 rotates, it drives the gears 10 to rotate, thereby driving the rack 7 to make linear motion, further driving the locking member 4 to slide in the docking device 3, realizing the switching of the clutch state. This structure, through the meshing between the gears 10 and the rack 7, efficiently converts the rotational motion into linear motion, making the action of the locking member 4 more precise and the response faster, improving the overall operation stability and control accuracy of the lock body.

[0034] Please refer to the details. Figures 1-4 A clutch assembly 11 is fixedly connected inside the housing 1.

[0035] In this embodiment: the clutch assembly 11, as a key transmission control component within the lock body, is used to engage or disengage the power transmission path under different operating states. Through linkage with components such as the locking member 4 and the push rod 12, it maintains the transmission path separation in the unauthorized state, preventing the square shaft 2 from driving the bolt. Upon receiving a correct unlocking signal, the push rod 12 drives the connector 13 into the clutch assembly 11, switching it to the transmission state, thereby allowing the handle operation to be converted into bolt driving action. This structure improves the safety and operational reliability of the lock through precise control of the clutch assembly 11.

[0036] Please refer to the details. Figures 1-4 A push rod 12 is slidably connected inside the clutch assembly 11, and a connector 13 is fixedly connected to one end of the push rod 12.

[0037] In this embodiment: the structure drives the mating head 13 to move by axially sliding the push rod 12 within the clutch assembly 11, so that the mating head 13 can engage or disengage with the docking slot 14 inside the docking device 3, thereby controlling the connection or disconnection of the power transmission path. In the unlocked state, the push rod 12 is driven by the control mechanism to drive the mating head 13 into the docking slot 14 to achieve transmission connection. In the locked state, the mating head 13 exits the docking slot 14, cutting off the transmission path and ensuring that the square shaft 2 cannot drive the locking tongue to move. This linkage method improves the accuracy and response speed of clutch control.

[0038] Please refer to the details. Figures 1-4 The docking device 3 has a docking slot 14, and a connector 13 is slidably connected in the docking slot 14.

[0039] In this embodiment: when the push rod 12 drives the connector 13 to slide along the docking slot 14 to the designated position, the connector 13 and the clutch assembly 11 form a transmission engagement, so that the rotation of the square shaft 2 can be transmitted to the locking tongue. In the locked state, the connector 13 disengages from the transmission area of ​​the docking slot 14 and cuts off the power output.

[0040] Please refer to the details. Figures 1-4 One end of the square shaft 2 is fixedly connected to a handle 15, and two limiting grooves 16 are opened in the housing 1. Two limiting sliders 8 are slidably connected in the two limiting grooves 16.

[0041] In this embodiment: the structure realizes operation input by rotating the square shaft 2 driven by the handle 15. The sliding trajectory of the limit slider 8 in the limit groove 16 is used to limit and guide the movement range of the control mechanism, ensuring that the rack 7 and gear 10 maintain a stable path during transmission, while providing directional constraints for the action of the locking member 4, making the clutch switching process more accurate and reliable, and improving the overall operation stability and linkage consistency of the lock body.

[0042] The working principle and usage process of this utility model: The user operates the handle 15 to drive the square shaft 2 to rotate, and the square shaft 2 drives the docking device 3 to rotate synchronously. The locking part 4 slides outward under the action of centrifugal force and compresses the spring 5. If the unlocking operation is not performed correctly, the locking part 4 cannot disengage from the limit state, the power transmission path is blocked, and the locking tongue does not move. When the user passes the identity verification, the control mechanism is activated, the drive shaft 9 rotates and drives the gear 10 to rotate, and the rack 7 meshing with it moves in a straight line, driving the locking part 4 to retract. At the same time, the limit slider 8 slides in the limit groove 16 to maintain a stable motion trajectory. The push rod 12 slides in the clutch assembly 11 and drives the docking device 1 to rotate. 3. Enter the docking slot 14 inside the docking device 3 to establish a transmission connection, so that the rotation of the square shaft 2 can be transmitted to the bolt to complete the unlocking. After unlocking, each component is reset under the action of the spring 5 and the control signal. The docking device 13 exits the docking slot 14, and the locking part 4 re-engages in the limit area to restore the locked state. This utility model has the function of preventing forced unlocking. When the square shaft, that is, the component connecting the door handle and the internal mechanism of the lock body, is shaken by external force or attempted to be pried by physical means, the two buckles can lock immediately to prevent any mechanical force from being transmitted to the bolt or lock. In this way, even if someone tries to forcibly open the door lock by shaking the handle, they will not succeed.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
