[0037] In order to make the purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0038] Reference Figures 1 to 5The application discloses an intelligent lock panel handle clutch device, which comprises a panel 100 and a handle 200 movably connected with the panel 100. The handle 200 extends to a position in the panel and is connected with a handle joint 301. An extension part is arranged on the side of the handle joint 301. A bottom disc is arranged in the panel 100 and is concentric with the handle joint 301. A screw 303 is vertically arranged on the extension part and faces the bottom disc 101. First protrusions 102 are symmetrically arranged on the two sides of the bottom disc 101. A clamping spring is arranged between the handle joint 301 and the bottom disc 101, and the two ends of the clamping spring abut against the first protrusions 102. The rotation track of the lower end of the screw 303 passes through one end of the clamping spring. When the door is opened, the handle 200 is rotated to drive the handle joint 301 to rotate, the handle joint 301 is driven by a clutch mechanism to realize the unlocking operation, the screw 303 on the extension part of the handle joint 301 abuts against one end of the clamping spring and compresses the clamping spring in the rotating process. When the handle 200 is released, the clamping spring releases the elastic force and is transmitted to the handle joint 301 through the lower end of the screw 303, so that the handle joint 301 drives the handle 200 to reset. Since the rotating diameter of the screw 303 is smaller than the distance between the two protrusions 102, when the handle is reset and the two ends of the clamping spring are restored and kept in abutment with the protrusions 102, the handle direction can be adjusted without disassembling the handle. When the intelligent lock panel handle clutch device is installed and the handle direction needs to be adjusted, the above-mentioned screw 303 is loosened, the upper end of the screw 303 is withdrawn upwards to a position that does not block the clamping spring, then the handle 200 is rotated by 180 degrees, and finally the screw 303 is tightened. Therefore, the above-mentioned problems, such as falling, losing or damaging of parts due to improper disassembly, can be avoided, the handle direction can be adjusted only by loosening the screw 303 to a certain extent, professional personnel are not needed for adjustment, and the adjustment can be completed only by rotating the screw 303. The application has a compact structure and is simple to operate, and greatly facilitates the installation and adjustment of installers. In addition, the device can be adjusted to adapt to left-opening and right-opening doors, and the operation is simple, so that the problem of wrong purchase and wrong installation can be avoided.

[0039] In the following, the intelligent lock panel handle clutch device in the application will be further described.

[0040] In the embodiment of the present application, a smart lock panel handle clutch device, wherein the handle joint 301 is symmetrically provided with two U-shaped grooves 302; the U-shaped groove 302 is perpendicular to the direction of the first protrusion 102; one side of the handle joint 301 is provided with a clutch 500, the middle part of the clutch 500 is connected with a lock body; the clutch 500 is provided with a movable pin 504 connected through a first spring 505; the first end of the movable pin 504 is connected with an arc-shaped push plate 401 of a safety mechanism, and the second end of the movable pin 504 is directed to the U-shaped groove 302 in the reset state, and the arc-shaped push plate 401 keeps the distance between the movable pin 504 and the abutting point of the push plate 401 relatively stable. When the handle 200 is in the reset state, that is, the U-shaped groove 302 is in the aligned state with the movable pin 504, the second end of the movable pin 504 is pushed into the U-shaped groove 302 by the push plate 401 of the safety mechanism, so that when the handle is rotated, the handle joint 301 can drive the clutch 500 to rotate together to realize unlocking; on the contrary, when the push plate 401 does not push the second end of the movable pin 504 into the U-shaped groove 302, the second end of the movable pin 504 is separated from the U-shaped groove 302 due to the elastic force of the spring, so that the clutch 500 is separated from the handle joint 301, at this time, when the handle 200 is rotated again, it can only drive the handle joint 301, and cannot drive the clutch 500 to rotate, so that it cannot be unlocked.

[0041] Further, the safety mechanism further comprises: a movable plate 402, the lower end of the movable plate 402 is connected with the push plate 401, and one side of the movable plate 402 is connected with the panel 100 through a second spring; the movable plate 402 is further provided with an inclined hole 405; the panel 100 is provided with a sliding piece 403 which can slide horizontally, and the sliding piece is provided with a connecting column 404 which extends into the inclined hole 405.

[0042] When the handle 200 is reset, the handle 200 can be locked by the sliding piece 403, so that the handle 200 can be switched to be unlocked or cannot be unlocked, which is equivalent to switching to a state, so that the handle 200 cannot be unlocked from the outside and the inside (anti-locking state), or it can also be set to a state that the handle 200 can be unlocked. Specifically, when the sliding piece 403 is pushed to move to an unlocking position, the sliding piece 403 drives the connecting column 404, and since the sliding piece 403 is in translation, the connecting column 404 moves the movable plate 402 through the inclined hole, thereby driving the push plate 401 to push the movable pin 504 into the U-shaped groove 302, so that the clutch 500 is connected with the handle joint 301, and then the handle 200 can drive the clutch 500 to rotate, and the clutch 500 is connected with the lock body, like Figure 5As shown, the insertion hole 501 of the clutch can be connected with the lock body through the insertion pin, thereby triggering the action of the lock body; conversely, when the sliding piece 403 is in the state of being locked, the sliding piece 403 is pushed to slide in the opposite direction, the push plate 401 is moved to the position away from the movable pin 504, and the movable pin 504 is popped out of the U-shaped slot 302 under the action of the first spring 505. In this state, the clutch 500 is not connected with the handle joint 301 (cannot be driven), so that when the handle 200 is rotated and drives the handle joint 301, the clutch 500 cannot be driven, thereby the handle cannot be unlocked. The upper end of the inclined hole 405 is provided with a horizontal direction extending for a certain length, so that when the force on the sliding piece 403 is removed, the sliding piece 403 can stop at the end of the inclined hole 405 without sliding, and is stable. It should be noted that the above-mentioned locking is to set the handle to an invalid unlocking state, rather than a state in which the handle cannot be moved.

[0043] As an application, for example, it can be used as a locking device of a smart electronic lock. The locking device can be driven by an internal motor component. For example, the sliding piece 403 can be driven to different states. When locking, the sliding piece 403 is driven to the locking position, and when unlocking, the sliding piece 403 is in the non-locking state.

[0044] In the embodiment of the present application, as shown in the drawings, Figure 5 As shown, the middle part of the clutch 500 is provided with a pin hole 501 for connecting with the lock body through the lock pin; the clutch 500 is symmetrically provided with a through hole 503, and the position of the through hole 503 is matched with the position of the screw 303. Through the above-mentioned through hole 503, when it is necessary to adjust the direction of the handle 200, the screw 303 can be loosened or removed from the position of the through hole 503 without taking down the clutch 500. Specifically, the sliding piece 403 can be pushed to the locking state, so that when the handle 200 is rotated, the clutch 500 will not rotate, the screw 303 is loosened, and then the handle 200 is rotated by half a circle, and then the screw 303 is tightened.

[0045] Further, the two sides of the through hole 503 are provided with a baffle 506 towards the direction of the chassis 101; the baffle 506 is located between the screw 303 and the first protrusion 102, and abuts against the two ends of the snap spring. Through the above-mentioned baffle 506, the snap spring can drive the clutch to reset at the same time when it drives the handle joint 301 to reset without affecting the transmission of the handle joint 301. The present application realizes the automatic resetting of multiple components by means of simple structure through ingenious design, and solves the problems of complex resetting structure and high cost of the same type of products.

[0046] In the embodiment of the present application, the through hole 503 is provided with a second protrusion 502 facing the direction of the screw 303; the rotation track of the screw head of the screw 303 away from the direction of the snap spring passes through the second protrusion 502.

[0047] Understandably, when the lock is opened or locked, the handle 200 of the door lock is generally screwed downward, and through the structure of the second protrusion 502, the handle can be operated reversely, that is, when the handle 200 is screwed upward, the lock can also be achieved, that is, when the handle 200 is lifted upward, the clutch 500 is driven to rotate by the screw head, and the lifting and locking function is achieved.

[0048] In the embodiment of the present application, the clutch 500 is further provided with an upper cover 507; the clutch 500 is provided with a containing groove at the lower end of the upper cover 507, the first spring 505 and the movable pin 504 are arranged in the containing groove, and the upper cover 507 is connected with the clutch 500 through a countersunk screw. Through the above combination, the movable pin 504 can be protected and limited in the containing groove, so that the stability can be maintained.

[0049] In the embodiment of the present application, a limiting groove can also be arranged on the chassis 101, the limiting groove is located on the rotation track of the screw 303, and the lower end of the screw 303 in the tightened state is located in the limiting groove.

[0050] It should be noted that the temperature state needs to be matched with a temperature sensor, such as a temperature sensing resistor and the like, and the temperature sensor and the application circuit are conventional technical means, which will not be described here.
