As shown in fig. 1 to 7, the embodiment of the present application provides a pot cover assembly for covering a pot body 5, and the pot cover assembly includes a support member 1, a pot cover body 3, a control member 2 and a transmission mechanism 4. The pot body 5 can be any cooking utensil, and pot teeth are arranged at the opening at the top of the pot body 5; the supporting piece 1 can be supported on the top of the pot body 5 and can be clamped with the pot body 5; the pot cover body 3 is rotationally connected below the supporting piece 1, the pot cover body 3 can rotate around the axis of the pot cover body 3, the pot cover body 3 is provided with cover teeth capable of being buckled with the pot teeth, and the pot cover body 3 is rotated relative to the pot body 5, so that the cover teeth on the pot cover body 3 and the pot teeth on the pot body 5 are buckled or separated from the buckle, and the pot cover body 3 and the pot body 5 are buckled with each other to cover or separate from the buckle to open the pot; the control part 2 is movably connected to the upper part of the support part 1, the control part 2 is operated to move, and the control part 2 can drive the pot cover body 3 to rotate through the transmission mechanism 4.

The transmission mechanism 4 includes a first transmission wheel 40 in transmission connection with the control member 2, the control member 2 directly or indirectly drives the first transmission wheel 40 to rotate around the axis of the pot lid body 3, for example, the rotation axis of the control member 2 coincides with the rotation axis of the pot lid body 3, and the first transmission wheel 40 is directly fixed to the rotation axis of the control member 2. The first driving wheel 40 is rotatably connected to the pot cover body 3, and a locking structure is arranged between the first driving wheel 40 and the pot cover body 3, and the locking structure can be any structure capable of realizing repeated locking and releasing under a proper condition, such as a matching structure of an elastic bolt and a slot. When the locking structure is locked, the first driving wheel 40 and the pot cover body 3 are fixed into a whole and linked, so that the first driving wheel 40 can be driven to drive the pot cover body 3 to rotate by operating the control part 2 to move, and the cover opening and closing operation is realized; when the cooker cover body 3 cannot rotate (for example, when the cooker cover body 3 is clamped), the locking structure is released, the first transmission wheel 40 moves along with the control piece 2, and the cooker cover body 3 is kept stationary, so that damage caused by overlarge stress of the transmission mechanism is avoided, and the transmission mechanism is protected; when the control piece 2 is operated reversely, the locking structure can be locked again, and the resetting of the transmission mechanism 4 is realized.

Further, the locking structure comprises an elastic buckle 402 and a lock cylinder 30 which are matched with each other, the lock cylinder 30 is clamped into the elastic buckle 402 to realize locking of the locking structure, or the lock cylinder 30 is separated from the elastic buckle 402 to realize releasing of the locking structure. One of the elastic buckle 402 and the lock cylinder 30 is disposed on the first driving wheel 40, and the other is disposed on the pot cover body 3; when the locking column 30 is clamped into the elastic buckle 402, the locking structure is locked, and the first driving wheel 40 and the pot cover body 3 are fixed into a whole and linked, that is, the first driving wheel 40 can drive the pot cover body 3 to rotate to open and close the cover; when pot cover body 3 is unable to rotate, along with the rotation of first drive wheel 40, elastic buckle 402 extrudes each other with lock post 30, makes elastic buckle 402 take place to warp, and elastic buckle 402 is deviate from to lock post 30, and the hasp structure loosens to make first drive wheel 40 rotate alone, avoid the too big production of drive mechanism 4 atress to damage.

The locking column 30 can be arranged in a shaft-shaped structure, the axis of the locking column 30 is parallel to the axis of the pot cover body 3, when the locking column 30 is clamped into the fixing groove 400, the side wall of the locking column 30 abuts against the elastic buckle 402 to form a larger contact area, so that a larger acting force can be transmitted between the locking column 30 and the elastic buckle 402, and the locking structure cannot be loosened under normal conditions; the lateral wall of the lock column 30 is a smooth arc surface, so that when the pot cover body 3 cannot rotate, the lock column 30 can slip along the elastic buckle 402, that is, when a large acting force is generated between the lock column 30 and the elastic buckle 402, the lock column structure is loosened. In addition, the rolling contact is formed between the lock cylinder 30 and the elastic buckle 402, so that the friction resistance between the lock cylinder 30 and the elastic buckle 402 can be reduced, and the abrasion failure between the lock cylinder 30 and the fixing groove 400 in the use process can be prevented. Of course, the lock cylinder 30 may be provided in any other suitable configuration, such as a block configuration with a ball head or a cone head, for example.

Further, the specific structure of the elastic buckle 402 disposed on the first driving wheel 40 and the locking column 30 disposed on the lid body 3 will be described.

The elastic buckle 402 includes a bayonet and at least one guiding leg 402a, the guiding leg 402 is formed by smoothly extending at least one side end of the buckle, and the lock cylinder 30 slides along the guiding leg 402a to be clamped into the elastic buckle 402 or to be separated from the elastic buckle 402. When the lock cylinder 30 slides to the bayonet, the lock cylinder 30 is clamped in the bayonet, and the lock catch structure is locked; when the lock cylinder 30 slides out of the bayonet along the guide leg 402a, the locking mechanism is released. The guide leg 402a may elastically abut against the first driving wheel 40 (the guide leg 402a may have elasticity, or the guide leg 402a may abut against the first driving wheel 40 through an elastic member), and the bayonet may be deformed by pressing the guide leg 402a, so that the lock cylinder 30 may be disengaged from the bayonet.

Specifically, when the lock cylinder 30 slides to one side (the side close to the bayonet) of the guide leg 402a, the lock cylinder 30 is clamped into the elastic buckle 402; when the pot cover body 3 is stuck, the locking column 30 presses the guide leg 402a along with the rotation of the control member 2, so that the bayonet is deformed, the locking column 30 slides to the other side (the side far away from the bayonet) of the guide leg 402a along the guide leg 402a, and the locking column 30 is separated from the elastic buckle 402.

Preferably, the elastic buckle 402 includes two guide legs 402a symmetrically disposed, and the guide legs 402a are formed by extending two side ends of the bayonet, that is, the bayonet is located between the two guide legs 402a, so that the elastic buckle 402 is more convenient to process and manufacture, and the first driving wheel 40 can rotate in both forward and reverse directions. When the lock cylinder 30 slides between the two guide legs 402a, the lock cylinder 30 snaps into the resilient catch 402 (see fig. 6); when the lock cylinder 30 slides to the outer side of the two guide legs 402a (the side where the two guide legs 402a face away from each other), the lock cylinder 30 comes out of the elastic catch 402 (see fig. 7). Of course, the elastic buckle 402 may include only one guiding foot 402a, so that the first driving wheel 40 can rotate only in one direction.

Further, the first driving wheel 40 is provided with a fixing groove 400, the fixing groove 400 may be disposed at an edge of the first driving wheel 40, and the elastic buckle 402 further includes a fixing portion 402b installed in the fixing groove 400; the fixing portion 402b is attached to a groove wall of the fixing groove 400, that is, an outer contour of the fixing portion 402b is adapted to an inner contour of the fixing groove 400, so that the elastic buckle 402 is fixed in the fixing groove 400, and the elastic buckle 402 is prevented from falling off under the squeezing action of the lock cylinder 30 and the elastic buckle 402; the bayonet is connected with the fixing part 402b and is clamped and fixed at the notch of the fixing groove 400, so that the locking column 30 is convenient to be matched with the bayonet; the guide leg 402a extends from at least one side end of the bayonet and protrudes out of the fixing groove 400 along a notch of the fixing groove 400.

Further, the size of the fixing groove 400 is shrunk at the notch to form a clamping neck, so that the elastic clamp 402 is prevented from being released along the notch of the fixing groove 400; the guide legs 402a extend from the two side ends of the bayonet and extend out of the fixing groove 400 by bypassing the clamping neck, so that the bayonet is located at the notch, the bayonet has smaller width, and the depth of the lock cylinder 30 extending into the fixing groove 400 is limited, so that the lock cylinder 30 can be smoothly separated from the bayonet; leave the clearance between the notch of bayonet socket and fixed slot 400, make the bayonet socket can take place to warp, that is to say, when lock post 30 extrudes the bayonet socket, one side of bayonet socket inclines to the direction of being close to the cell wall of fixed slot 400, and the clearance between this side bayonet socket and the notch reduces, perhaps the bayonet socket is laminated with the notch mutually, and lock post 30 follows guide foot 402a roll-off bayonet socket.

Further, a fixing column 404 is disposed in the fixing groove 400, and the fixing portion 402b is sleeved on the fixing column 404 and is clamped between the fixing column 404 and the fixing groove 400. That is to say, the fixing column 404 is close to the groove wall of the fixing groove 400, and forms an installation gap with the groove wall of the fixing groove 400, and the elastic buckle 402 is clamped in the installation gap, so as to further ensure the installation reliability of the elastic buckle 402, and effectively prevent the elastic buckle 402 from falling off in the use process.

Further, a gap may be left between the fixing groove 400 and the edge of the first driving wheel 40, and at this time, the first driving wheel 40 may be provided with a limiting groove 406, and the limiting groove 406 is disposed outside the notch of the fixing groove 400 and penetrates through the first driving wheel 40 along the thickness direction of the first driving wheel 40. The limit groove 406 is configured to be an arc structure corresponding to the sliding track of the lock cylinder 30, and the lock cylinder 30 passes through the limit groove 406 and is clamped into the elastic buckle 402; when the lock cylinder 30 is disengaged from the resilient catch 402, the lock cylinder 30 can slide along the retaining groove 406. On one hand, the locking column 30 is guided by the limiting groove 406, so that the relative rotation between the first driving wheel 40 and the pot cover body 3 is more stable; on the other hand, the lock column 30 is limited by the limiting groove 406, so that the first driving wheel 40 and the pot cover body 3 are prevented from rotating relatively at an overlarge angle, and the resetting of the lock catch structure is facilitated.

The guiding pin 402a should extend into the limiting groove 406 and elastically abut against the groove wall of the limiting groove 406, and the lock cylinder 30 can always abut against the guiding pin 402a and slide along the guiding pin 402a, so as to prevent the lock cylinder 30 from being jammed and causing the lock structure to be difficult to reset.

Preferably, the transmission mechanism 4 provided in the embodiment of the present application further includes a second transmission wheel 42, and a tooth-shaped structure is disposed between the first transmission wheel 40 and the second transmission wheel 42, that is, the first transmission wheel 40 and the second transmission wheel 42 form a gear structure; the second transmission wheel 42 is fixedly connected to the rotating shaft 20 of the control part 2, the control part 2 drives the second transmission wheel 42 to rotate, and the second transmission wheel 42 drives the first transmission wheel 40 to rotate.

Preferably, the diameter of the second transmission wheel 42 is smaller than that of the first transmission wheel 40, so that a larger moment is generated on the first transmission wheel 40, and a user can open and close the cover more easily. The first driving wheel 40 may be provided with tooth-like structures along the circumferential direction, or a corresponding second driving wheel 42 on the first driving wheel 40 may be provided with a tooth-like structure at a local section.

Preferably, the control member 2 includes a rotating shaft 20, an axis of the rotating shaft 20 is perpendicular to an axis of the pot cover body 3, the control member 2 rotates around the rotating shaft 20 in a direction close to the pot cover body 3 and is attached to the pot cover body 3 (see fig. 2), or the control member 2 rotates around the rotating shaft 20 in a direction away from the pot cover body 3 and is perpendicular to the pot cover body 3 (see fig. 1), so as to define an angle of rotation of the control member 2, further define an angle of rotation of the transmission mechanism 4 relative to the pot cover body 3, and facilitate resetting of the transmission mechanism 4. The first driving wheel 40 and the second driving wheel 42 are meshed with each other to form a bevel gear transmission structure, and the transmission direction is changed through bevel gear transmission, so that the pot cover body 3 can rotate around the axis of the pot cover body.

Preferably, the control member 2 is a handle, that is, when the lid assembly has a rotatable handle, the first driving wheel 40 can be directly driven and connected to the handle, so that the number of parts of the lid assembly is reduced, and the structure of the lid assembly is simplified.
