The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 13, the handle joint of the door lock panel 9 with a clutch according to the present invention includes:

the rotary disk main body 1, as shown in fig. 1, 12 and 13, is provided with a handle mounting structure on one surface for mounting and connecting the handle assembly 11, and the specific shape and structure of the handle mounting structure can be designed according to the handle assembly 11; as shown in fig. 1, a rotary station 2 is arranged on the other side, and a clutch rotor 21 of the clutch can be arranged in the rotary station 2;

a clutch pin 3, as shown in fig. 2, 3 and 10, which is slidably provided on the other face of the rotating disc main body 1 along its central axis; and a clutch pin 3 close to one end 3232 of the rotating station 2 can be inserted into the rotating station 2 in a sliding manner, specifically, a limiting installation structure (such as a groove, a cavity and the like) is arranged on the rotating disc main body 1 to provide a limited sliding range for the clutch pin 3, so that the clutch pin 3 is installed on the rotating disc main body 1 and can slide along the central axis of the clutch pin 3 under external force, and a through hole aligned with the clutch pin 3 is formed in the rotating station 2 for the clutch pin 3 to be inserted and withdrawn in a sliding manner; an elastic pressing piece 4 is further arranged between the clutch pin 3 and the rotating disc main body 1, the elastic pressing piece 4 applies elastic force to the clutch pin 3 to enable the clutch pin 3 to tend to be away from the rotating station 2, concretely, the elastic pressing piece 4 can adopt a spring and is sleeved on the periphery of the clutch pin 3, two ends of the spring are respectively limited on the surfaces of the limiting installation structure and the clutch pin 3, the clutch pin 3 is stressed to slide and displace towards the rotating station 2, the relative distance between two ends of the spring is shortened, elastic deformation increases elastic potential energy, and the clutch pin 3 can be reset to the position before sliding when external force is cancelled;

as shown in fig. 9, the sliding block 5 has a through passage 51 formed in the middle thereof for movably engaging with the outer periphery of the clutch pin 3; the inner wall of the through passage 51 is provided with a convex locking portion 52;

as shown in fig. 4, when the protruding locking portion 52 abuts and locks the clutch pin 3, the clutch pin 3 is prevented from sliding to a position where the rotating disk main body 1 and the clutch rotor 21 can be interlocked with each other.

Therefore, when the clutch rotor 21 is rotatably arranged on the rotating station 2, the clutch pin 3 can be clamped as long as the sliding block 5 is positioned so that the protruding locking part 52 in the sliding block 5 abuts against the clutch pin 3, thereby preventing the clutch pin 3 from being further forced to slide and inserted into the rotating station 2, preventing the clutch pin 3 from being inserted into the rotating station 2, enabling the handle joint and the clutch rotor 21 to relatively independently rotate, and enabling the clutch pin 3 to be a connecting piece for linking the handle joint and the clutch rotor 21. Therefore, the sliding position of the clutch pin 3 can be limited by the convex locking part 52 of the sliding block, so that the clutch pin 3 can be prevented from being inserted into the clutch rotor 21 of the rotating station 2 under the condition of an unreasonable state by the sliding block, the clutch rotor 21 cannot be in linkage connection with the handle joint, and a safety guarantee is provided for the handle joint and the clutch or door lock panel 9 comprising the handle joint.

In order that the sliding block 5 can slide to the position where the protruding locking part 52 collides and locks the clutch pin 3 more accurately in the sliding range, further, a one-way inclined guiding and limiting structure 6 is further arranged on the other surface of the rotating disc main body 1; the sliding block 5 is movably arranged in the guide limiting structure 6; under the direction guide of direction limit structure 6, sliding block 5 receives external force displaceable to the card limit position, and when sliding block 5 was located the card limit position, protruding locking part 52 contradicted and locked separation and reunion round pin 3 to hinder separation and reunion round pin 3 to slide to the position that can link handle joint and separation and reunion rotor 21. The sliding range of the sliding block 5 is limited by the guiding and limiting structure 6, and the guiding and limiting structure 6 is designed into a structural shape with one-way inclination. Under the dynamic state of external force: the slide block 5 is moved by an external force along the direction of the inclined extension of the guide limit structure 6, which guides the slide block 5 to slide to the engagement position, so that the protruding lock portion 52 can abut and lock the clutch pin 3.

Further, one end of the guiding and limiting structure 6, which is close to the clutch rotor 21, is a limiting end 61, and the other end is a placing end 62; the locking position is located in a path of the sliding block 5 moving from the placing end 62 to the limiting end 61 under the action of external force. That is, during the process of moving the sliding block 5 from the placing end 62 to the limiting end 61 by the external force, the protruding locking part 52 will move to abut against and lock the clutch pin 3 along with the sliding block 5. Specifically, the handle joint is installed on the panel of the door lock panel 9 in a conventional assembly manner, the sliding block automatically falls on the placing end 62 under the action of gravity, and if the sliding block 5 is driven by external force, the sliding block moves from the placing end 62 to the limiting end 61 along the guiding and limiting structure 6. It is because the guiding and limiting structure 6 is designed to be inclined, during this movement, the entire sliding block 5 is displaced not only in the longitudinal direction but also in the transverse direction (for convenience of description and understanding, the longitudinal and transverse directions are referred to herein based on the mounted state of the clutch pin 3 in the longitudinal direction as shown in fig. 4); meanwhile, since the sliding of the clutch pin 3 is restricted to be performed only along the central axis thereof, that is, in the longitudinal direction, during the process of moving the slide block 5 from the placing end 62 to the limiting end 61, the distance between the protruding locking portions 52 and the clutch pin 3 in the transverse direction is shortened, so that the space where the through channel 51 in the middle of the slide block 5 is aligned with the clutch pin 3 is narrowed, the clutch pin 3 cannot slide in the through channel 51, and therefore, the clutch pin cannot be inserted into the rotation station 2 to be linked with the clutch rotor 21.

Further, as shown in fig. 5 and 6, the convex lock portion 52 protrudes from the inner wall of the slide block 5 on one side; and the sliding block 5 is in the slidable range in the guide limit structure 6, when the sliding block 5 is positioned at the placing end 62, the distance between the convex locking part 52 and the clutch pin 3 is farthest, so that the through channel 51 provides the largest sliding space for the clutch pin 3 in a normal state; and, before protruding locking portion 52 collides against clutch pin 3, clutch pin 3 can freely slide in through channel 51 of slide block 5 to ensure that clutch pin 3 can be smoothly inserted into rotation station 2 by force under normal state. It should be noted that, as shown in fig. 5 and 6, the protruding locking portion 52 is formed by protruding a layer of circular arc protrusion on the inner wall of the through channel 51, so that the diameter of the through channel 51 is reduced, and the shape structure of the protruding locking portion 52 can be changed according to the locking with the clutch pin 3, for example, the shape of the square protrusion, the protrusion formed along the shape of the inner wall, the shape of the strip protrusion, and the like, and the thickness of the protrusion and the specific position change in the through channel 51 all belong to the protection scope of the present invention.

In order to ensure the locking action to be effective and stable under uniform stress, the convex locking part 52 is further provided with a fitting end surface, and the shape of the fitting end surface is matched with the shape of the side surface of the clutch pin 3. For example, if the clutch pin 3 is cylindrical, the mating end face of the convex locking portion 52 is also designed as a matching circular arc end face; the protruding locking portion 52 abuts against the side surface of the clutch pin 3 through the fitting end surface, and due to the shape mutual fitting, the protruding locking portion can abut against each other in a fitting manner, thereby ensuring the locking effect.

In order to further ensure the locking effect, as shown in fig. 7, a locking engagement portion 31 is provided on a side surface of the clutch pin 3 and on an end portion thereof remote from the clutch rotor 21; protruding sticking department 52 of sliding block 5 is through contradicting the locking cooperation portion 31 on clutch pin 3 surface with locking clutch pin 3 to the realization hinders clutch pin 3 to slide to the position that can link rotating disc main part 1 and clutch rotor 21, and sliding block 5 is in promptly during the card limit position, protruding sticking department 52 in the sliding block 5 and the mutual conflict of locking cooperation portion 31 on clutch pin 3 surface are spacing, thereby realize hindering clutch pin 3 to the further slip of clutch rotor 21 direction. By changing the position of the projection lock portion 52 in the above-described lateral direction such that the projection lock portion 52 is obstructed in the sliding path of the lock engagement portion 31 in the above-described longitudinal direction, the projection lock portion 52 can catch the lock engagement portion 31, so the space where the through passage 51 is aligned with the clutch pin 3 is insufficient for the lock engagement portion 31 provided on the side surface of the clutch pin 3 to pass through, and therefore, the clutch pin 3 cannot be further slidably inserted into the rotation station 2. It should be noted that the change of the shape and structure of the locking engagement portion 31 and the specific arrangement position on the clutch pin 3 can be adaptively changed according to the specific design condition of the protrusion locking portion 52, which all belong to the protection scope of the present invention. For example, the lock engagement portion 31 is a protruding ring (as shown in fig. 8) or a groove or the like provided on an end portion of the clutch pin 3 remote from the clutch rotor 21, and is a limit structure capable of engaging with the protruding lock portion 52 to lock the clutch pin 3.

In order to optimize the overall structure of the handle joint, the guide limiting structure 6 is a non-rectangular parallelogram containing groove, and the side wall of the containing groove is required to play a role in limiting and guiding the inclination, so that the rectangular containing groove is not in line with the theory; the outer contour of the sliding block 5 is also in a shape matched with the containing groove; the space in the groove of the containing groove can be used for the movable displacement of the sliding block 5; and the sliding block 5 can be guided to move to the clamping limit position through the side wall of the containing groove. Through the structure that designs into the storage tank with direction limit structure 6, not only can slide the atress of sliding block 5 and play the guide effect, can also play the restriction effect of slip scope to sliding block 5, so play protection and installation effect to sliding block 5, also easy operation when producing the equipment. Of course, should not understand direction limit structure 6 as the structure that is only limited to the storage tank, for example set up several can play spacing structures such as protruding panel beating or lug of the equal spacing effect of direction, sliding block 5 is movably set up wherein, also belongs to the utility model discloses a protection scope.
