While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 and 2 show a schematic structural view of a pot cover 400 in a locked state according to an embodiment of the present invention; fig. 3 and 4 are schematic structural views illustrating the pot cover 400 according to an embodiment of the present invention when the lock catch 310 is disengaged from the positioning groove 321; fig. 5 and 6 are schematic structural views illustrating the pot lid 400 in an unlocked state according to an embodiment of the present invention.

As shown in fig. 1 to 6, the pot cover 400 includes a cover body 100, a support member 200 and a locking member 300, the support member 200 is located above the pot cover 400 and detachably mounted on the top surface of the cover body 100, the cover body 100 can rotate relative to the support member 200, and the locking member 300 is detachably connected to the cover body 100. In practical application, both ends of the supporting member 200 are fixedly connected to the pot body, and the cover body 100 is opened or closed with respect to the pot body by operating the cover body 100 to rotate with respect to the pot body and the supporting member 200.

According to one embodiment, as shown in fig. 2, 4 and 6, the center of the cover body 100 is provided with the center post 150, and the center of the support member 200 is provided with the center hole 250. The supporting member 200 is sleeved on the central column 150 through the central hole 250, and the width of the central hole 250 is larger than that of the central column 150, so that a certain accommodating space is still formed between the central hole 250 and the central column 150, and the locking member 300 can be sleeved on the central column 150 and accommodated in the central hole 250. It will be appreciated that when the locking member 300 is not mounted, the center post 150 can move relative to the center hole 250, and the support member 200 can be upwardly separated from the center post 150 through the center hole 250, so that the support member 200 can be separated from the cover body 100.

As shown in fig. 2, the locking member 300 is detachably installed in the central hole 250 and is fixedly connected to the central column 150, and the upper end of the locking member 300 has a step portion 354, and the upward movement of the support member 200 can be limited by the step portion 354, so that the support member 200 is prevented from being separated from the cover body 100, and the support member 200 is locked to the cover body 100. In the locked state, since the locking member 300 is fixed to the cover 100 and the central column 150 and the locking member 300 are both located in the central hole 250, the central column 150 and the locking member 300 can rotate in the central hole 250 by rotating the cover 100, that is, when the cover 100 is used as a reference, the locking member 300 is fixed and the central hole 250 of the support member 200 rotates relative to the central column 150 and the locking member 300. Therefore, after the locker 300 is mounted, the support member 200 and the cover body 100 cannot be separated from each other, and the support member 200 can only be rotated with respect to the center of the cover body 100. In addition, as shown in fig. 5 and 6, when the lid 400 is unlocked, the support member 200 can be separated from the center post 150 upward through the center hole 250 after the locking member 300 is removed from the center post 150 by detaching the locking member 300 from the center post 150, so that the support member 200 can be separated from the lid body 100, that is, the unlocked state of the support member 200 from the lid body 100.

Further, as shown in fig. 2 and 4, locking member 300 includes a connecting member 351, and connecting member 351 is adapted to be fixedly connected to central column 150. Wherein, the upper end of the central column 150 is provided with a thread groove 151. The side wall of the connection member 351 is provided with an external thread engaged with the thread groove 151, so that the connection member 351 can be inserted into the thread groove 151 and rotated to be threadedly coupled with the thread groove 151, thereby fixedly coupling the connection member 351 with the center post 150.

Further, as shown in fig. 2 and 4, a positioning groove 321 is axially formed in the central hole 250, and the locker 300 further includes a locker 310. The locking member 300 has a receiving groove 337 above the positioning groove 321, the receiving groove 337 is connected to the positioning groove 321, the latch 310 is slidably mounted in the receiving groove 337, and the latch 310 can be moved along the receiving groove 337, i.e., toward or away from the positioning groove 321, by pressing the latch 310, so as to be locked to or released from the positioning groove 321. Here, when the locker 310 is locked to the positioning groove 321 by an operation, the locking member 300 can be restricted from rotating with respect to the center post 150, thereby preventing the connecting member 351 from being unintentionally unscrewed from the thread groove 151 of the center post 150, and enhancing the stability of the connection of the locking member 300 and the center post 150 in a locked state.

It can be understood that when the cover 400 is to be unlocked, the lock catch 310 is first disengaged from the positioning slot 321 by operation, as shown in fig. 4; retaining member 300 can then be removed from central bore 250 by rotating retaining member 300 to unscrew connecting member 351 from threaded channel 151.

Specifically, as shown in fig. 2, 4 and 6, the locker 300 further includes a hollow cylinder 350 having a hollow structure, and a position sleeve 320. As shown in fig. 7b and 7c, a head 353 is formed extending upward from the top of the hollow cylinder 350. Wherein, the hollow column 350 is inserted into the central hole 250 and sleeved outside the central column 150, and a space is present between the hollow column 350 and the central column 150. The connecting member 351 extends downward from the head portion 353 to the hollow cavity of the hollow column 350, and is coaxially disposed with the hollow column 350, so that the connecting member 351 can extend into the threaded groove 151 of the central column 150 to be fixedly connected with the threads thereof.

As shown in fig. 6, the positioning sleeve 320 has a central shaft hole 325 extending through the axial direction, the positioning sleeve 320 is sleeved on the central column 150 through the central shaft hole 325, and the outer wall of the positioning sleeve 320 abuts against the inner wall of the hollow column 350, so that the positioning sleeve 320 can be stably installed in the central hole 250 and fixed in the hollow column 350. Here, the positioning sleeve 320 and the hollow column 350 are of a split structure and can be separated from each other, and the positioning sleeve 320 can be separately sleeved on the central column 150 and also can be detached from the central column 150. As shown in fig. 8, the outer wall of the positioning sleeve 320 is recessed to form the positioning groove 321, so that the positioning groove 320 is located in the hollow cylinder 350.

As shown in fig. 7b and 7c, the head 353 has the receiving groove 337 penetrating therethrough, and the receiving groove 337 has an open upper end, and the lower end of the receiving groove 337 is communicated with the hollow cylinder 350 through the through hole, so that the latch 310 slides along the receiving groove 337 by pressing the latch 310, and extends into the positioning groove 321 in the hollow cylinder 350 through the through hole to be engaged with the positioning groove 321.

Further, as shown in fig. 7b and 7c, the head 353 extends horizontally outward to form the above-mentioned step 354. The top of the supporting member 200 extends downward to form a stopping portion 240, and the stopping portion 240 stops on the outer wall of the step portion 354, so that the supporting member 200 is limited from moving upward and separating relative to the cover body 100.

According to one embodiment, as shown in fig. 7b and 7c, the latch 310 includes a core 311, a latch head 353, and an elastic member 313, and the core 311 may be formed by extending the latch head 353 downward. The latch 310 moves relative to the receiving slot 337 by pressing the latch portion 353, so that the core 311 can extend downward into the positioning slot 321 and engage with the positioning slot 321. In addition, the elastic element 313 is disposed on the core 311, and the elastic element 313 elastically pushes against between the latch 310 and the inner wall of the receiving slot 337. The elastic member 313 may be a spring, but is not limited thereto.

Specifically, as shown in fig. 7c and 7d, the lock head portion 353 may be a cylindrical cavity with an open end, the core 311 is formed by extending a top wall of the lock head portion 353 downward, a lower end of the core 311 protrudes out of the lock head portion 353 downward, and two ends of the elastic member 313 respectively abut against the top wall of the lock head portion 353 and an inner wall of the accommodating groove 337. When the locking head 353 is pressed downward, the elastic member 313 is pressed, and the core 311 is driven to move downward to extend into the positioning groove 321 to be locked with the positioning groove, as shown in fig. 2, at this time, the locking head 353 stops at the inner wall of the accommodating groove 337, so as to limit the latch 310 from moving downward.

It will be appreciated that when the latch 353 is no longer pressed, the resilient restoring force of the compressed resilient member 313 can urge the latch 353 and the core 311 to move together upward, thereby disengaging the core 311 from the positioning groove 321, as shown in fig. 4.

According to one embodiment, as shown in FIGS. 2 and 7c, the locker 300 further includes an operating member 330, the operating member 330 is mounted on the top of the head 353, and the operating member 330 is disposed above the latch 310 so as to be capable of abutting against the latch head 353 of the latch 310. As shown in fig. 7b, the operating member 330 includes an arc-shaped pressing protrusion 332, and the pressing protrusion 332 is located opposite to the accommodating slot 337, so as to be capable of being engaged with and abutting against the latch 310 in the accommodating slot 337. Specifically, the operation member 330 is rotated by operation to drive the pressing protrusion 332 to rotate to push against the lock head 353 of the lock catch 310, so that the lock catch 310 moves along the accommodating slot 337 toward the positioning slot 321, and the lock catch 310 extends into the positioning slot 321 to be locked with the positioning slot 321. In addition, the press tab 332 can also be rotated out of the way of the latch head 353, thereby releasing the latch 310.

Further, as shown in fig. 7b to 7d, the operating member 330 further includes a handle 333, and the handle 333 can be snapped on top of the step portion 354. The handle 333 is arcuate, and may be, for example, a semi-circular rod. The handle 333 has two ends extending horizontally inward to form a rotation axis 331, where "inward" is a direction toward the opposite end. The rotation shaft 331 can be fastened to the top of the head 353 and horizontally disposed right above the receiving slot 337, so that both the handle 333 and the rotation shaft 331 can rotate around the axis of the rotation shaft 331 by pulling up or pressing down the handle 333, that is, the rotation shaft 331 rotates.

The pressing protrusion 332 is an arc-shaped protrusion protruded from the rotation shaft 331 of the handle 333, and is specifically protruded in a direction away from the axis of the rotation shaft 331 and toward the handle 333, and a plane of the arc-shaped protrusion is perpendicular to a plane of the handle 333. Thus, when the operating handle 333 is rotated, the rotating shaft 331 rotates, and the arc-shaped protrusion can rotate along with the handle 333 and the rotating shaft 331, thereby pushing the latch 310 to move along the receiving slot 337.

According to one embodiment, as shown in fig. 7b, the pressing protrusion 332 may be a semicircular protrusion protruded from the rotation shaft 331.

Specifically, as shown in fig. 7d, when the handle 333 is in the vertical position, the pressing protrusion 332 rotates above the rotating shaft 331, so that the pressing protrusion 332 does not abut against the latch 310 in the receiving slot 337, and the latch 310 is disengaged from the positioning slot 321. When the handle 333 is pressed downwards to rotate the handle 333 from the vertical position to the horizontal position, the pressing protrusion 332 rotates from above the rotating shaft 331 to a position partially below the rotating shaft 331, and in the process, the pressing protrusion 332 can abut against the locking head 353 of the lock catch 310, so that the lock catch 310 moves vertically downwards along the accommodating groove 337, and the core 311 extends into the hollow cylinder 350 and is locked in the positioning groove 321, as shown in fig. 7c and fig. 2. Through the arrangement, the pressing protrusion 332 is driven to rotate to push against the lock catch 310 to move by the operating handle 333, so that the core body 311 moves into the positioning groove 321 to be buckled with the positioning groove 321, the locking member 300 can be limited to rotate relative to the central column 150, and the locking member 300 and the central column 150 are prevented from being unscrewed due to misoperation.

In addition, when the handle 333 is rotated from the horizontal position to the vertical position, since the pressing protrusion 332 is no longer abutted to the latch 310, thereby releasing the latch 310, at this time, the elastic restoring force of the elastic member 313 can push the latch portion 353 and the core 311 to move upward along the receiving slot 337, so that the core 311 can be disengaged from the positioning slot 321, as shown in fig. 4 and 7d, and at this time, the latch 300 can be rotated to be unscrewed from the center post 150.

Through the above arrangement, as shown in fig. 1 and 2, the locking member 300 is accommodated in the central hole 250, the connecting member 351 is fixedly connected with the central column 150 by screwing the locking member 300, and the operating handle 333 is rotated to the horizontal position to fasten the lock catch 310 to the positioning slot 321, so that the locking member 300 is prevented from being rotated in the opposite direction relative to the central column 150 and unscrewed, thereby preventing the misoperation and firmly locking the supporting member 200 and the cover body 100.

According to one embodiment, as shown in fig. 8, the outer wall of the positioning sleeve 320 is recessed inward to form a plurality of positioning grooves 321, each positioning groove 321 penetrates from the top to the bottom of the positioning sleeve 320 along the axial direction, and the plurality of positioning grooves 321 are uniformly arranged along the circumferential direction of the positioning sleeve 320, so that any one of the positioning grooves 320 is aligned with the core 311 after the positioning sleeve 320 is installed. Specifically, the locating slot 321 is formed by the outer wall of the locating sleeve 320 firstly recessing inwards along the inclined plane to form a notch, and then further recessing inwards along the arc surface, so that the opening of the locating slot 321 is in an expanded arc shape, and the core 311 slides into the locating slot 321 to be buckled.

In addition, a space is provided between two adjacent positioning grooves 321, which are not communicated. Thus, after the entire locker 300 is mounted in the central hole 250 and the connecting member 351 is threadedly coupled to the threaded groove 151, the outer wall (non-recessed portion) of the positioning sleeve 320 abuts against the inner wall of the hollow cylinder 350, so that the sidewall of the positioning groove 321 is relatively sealed, and the core 311 of the locker 310 can be stably fastened in the positioning groove 321 without being separated from the side of the positioning groove 321.

According to one embodiment, as shown in FIGS. 7a to 7d, the locker 300 further includes a fixing cap 340, and the fixing cap 340 is covered over the head 353. The handle 333 may be provided around the outer circumference of the fixed cover 340 so as to be rotatable around the fixed cover 340 over the fixed cover 340. The rotation shaft 331, the pressing protrusion 332, and the locker 310 are all located under the fixing cover 340, and thus are shielded by the fixing cover 340, so that the overall appearance of the locker 300 is more beautiful.

According to one embodiment, as shown in fig. 2, 4 and 6, the supporter 200 includes a fixing portion 280 at a lower end and a top cover 290 snap-coupled to a top surface of the fixing portion 280, and a receiving space is formed between the top cover 290 and the fixing portion 280. The top cover 290 is provided with a through hole for exposing the handle 333 and the fixing cover 340, the fixing cover 340 protrudes out of the supporting member 200 through the through hole of the top cover 290, the handle 333 also protrudes out of the supporting member 200 when rotating to have an included angle with the horizontal position, so that the handle 333 is operated to drive the pressing protrusion 332 to push against the latch 310 to move, so that the latch 310 is latched with or disengaged from the positioning slot 321.

Specifically, as shown in fig. 6, a stopping portion 240 is provided at the through hole of the top cover 290 and extends downward to match with the step portion 354. When the locker 300 is mounted in the center hole 250, as shown in fig. 2, the stopping portion 240 can be stopped at the outer wall of the stepped portion 354, so that the supporter 200 cannot be moved upward with respect to the cover body 100, and cannot be separated from the cover body 100.

In addition, in the embodiment according to the present invention, as shown in fig. 1 to 6, two limiting columns 110 are symmetrically disposed on the cover body 100 relative to the center of the cover body 100. Correspondingly, two arc-shaped grooves matched with the limiting columns 110 are symmetrically arranged on the supporting piece 200 relative to the center of the supporting piece 200, and when the cover body 100 rotates relative to the supporting piece 200, the limiting columns 110 are driven to slide along the arc-shaped grooves. The arc-shaped groove comprises an end with a relatively large width, specifically, the width of any one end of the arc-shaped groove is larger than the section width of the top of the limiting column 110, and the width of the rest part of the arc-shaped groove except the end is smaller than the section width of the top of the limiting column 110. Therefore, when the cover 100 rotates relative to the supporting member 200, the limiting column 110 is driven to slide relative to the arc-shaped groove, and when the cover slides to the end with the larger width, the end can be separated from the arc-shaped groove, that is, the supporting member 200 can be separated from the limiting column 110 upwards through the arc-shaped groove.

When the pot cover 400 needs to be disassembled and washed, the cover body 100 is rotated relative to the center of the support member 200 by rotating the cover body 100, and simultaneously the limiting column 110 is driven to slide relative to the arc-shaped groove, and the limiting column 110 slides to the end with larger width along the arc-shaped groove. At this time, by rotating the operating handle 333 to the vertical position, as shown in fig. 4, the lock catch 310 is disengaged from the positioning slot 321, and the rotation of the lock member 300 is no longer restricted. Retaining member 300 is then removed from central aperture 250 by rotating retaining member 300 to unscrew it from central post 150, as shown in FIG. 6, so that retaining member 300 no longer presses against support member 200. Thus, the supporting member 200 can be upwardly separated from the central post 150 through the central hole 250, and the end of the arc-shaped groove having a larger width can also be separated from the stopper post 110, so that the supporting member 200 can be detached from the cover body 100 to clean the pot cover 400. Here, in the process of detaching the pot cover 400, the engagement of the limiting post 110 and the arc-shaped groove plays a guiding role for the relative rotation of the cover body 100 and the supporting member 200, and can assist the detachment and separation of the supporting member 200 and the cover body 100.

Further, in order to more easily detach the supporter 200 and the cover 100, as shown in fig. 1, 3 and 5, the arc-shaped groove includes a guide groove 210 of a first section and an offset groove 215 of a second section smoothly connected to the guide groove 210 of the first end. It should be noted that the width of the guiding groove 210 is smaller than the cross-sectional width of the top of the position-limiting post 110, so as to stop at the top of the position-limiting post 110, and the width of the offset groove 215 is larger than the cross-sectional width of the top of the position-limiting post 110, so as to be capable of separating from the position-limiting post 110 upwards.

Specifically, as shown in fig. 9 and 10, the positioning column 110 includes a cylinder 111 and a circular truncated cone 112 located at a top end of the cylinder 111, a step surface is formed between the circular truncated cone 112 and the cylinder 111, one end of the cylinder 111 away from the circular truncated cone 112 is fixedly connected to the cover 100, a width of the guide groove 210 is smaller than a diameter of the circular truncated cone 112, and a width of the offset groove 215 is larger than the diameter of the circular truncated cone 112. As shown in fig. 1, 3 and 5, the guide groove 210 has an arc-shaped bar shape, and the offset groove 215 has an arc-shaped block shape. Through the arrangement, the column body 111 of the limit column 110 can penetrate through the guide groove 210 and is stopped on the top surface of the guide groove 210 through the circular truncated cone 112, namely the guide groove 210 is stopped below the circular truncated cone 112, so that the guide groove 210 cannot be separated from the limit column 110 upwards; since the width of the offset groove 215 is greater than the width of the circular truncated cone 112, the offset groove 215 can be separated from the stopper 110 upward.

As shown in fig. 1 and 2, in a state when the supporting member 200 and the lid 100 are locked firmly, when the pot lid 400 needs to be disassembled and washed, the lid 100 is rotated relative to the central hole 250 of the supporting member 200, and the position-limiting column 110 is driven to slide along the guide groove 210 and can slide to one end of the guide groove 210 communicating with the offset groove 215. In the process, the guide groove 210 stops below the circular truncated cone 112 and cannot be separated from the limit posts 110, and the sliding tracks of the two limit posts 110 in the corresponding guide grooves 210 are symmetrical relative to the center of the support member 200.

Further, as shown in fig. 4, by rotating the operating handle 333 to the vertical position, the lock catch 310 is disengaged from the positioning groove 321, and the rotation of the lock member 300 is no longer restricted, and then the lock member 300 is rotated to be unscrewed from the center post 150, so that the lock member 300 is taken out from the center hole 250, and the lock member 300 is no longer pressed against the support member 200, as shown in fig. 6. When the cover 100 is rotated, the supporting member 200 rotates eccentrically with respect to the cover 100, and drives the two positioning posts 110 to move in the moving slots 215. Since the support member 200 can be upwardly separated from the stopper post 110 by the offset groove 215 and the locker 300 does not restrict the upward movement of the support member 200, the support member 200 can be upwardly separated from the center post 150 by the center hole 250, and thus, the support member 200 can be upwardly removed to be separated from the cover body 100. It should be noted that, after the locking member 300 is removed, the offset tracks and distances of the two spacing posts 110 in the corresponding offset slots 215 are different because the supporting member 200 rotates eccentrically relative to the cover 100.

In addition, as shown in fig. 1 to 6, a connection column 130 is further disposed in a region of the cover body 100 deviating from the central column 150, specifically, the connection column 130 is disposed in a region between the central column 150 and the limiting column 110. Accordingly, the supporting member 200 is provided with a coupling hole 230 in a region offset from the central hole 250, and as shown in fig. 1, the coupling hole 230 has an arc shape, so that the coupling post 130 can relatively rotate and relatively slide in the coupling hole 230. The supporting member 200 is rotatably sleeved on the connecting post 130 through the connecting hole 230 and can eccentrically rotate around the connecting post 130 relative to the cover body 100. Specifically, in the case of installing the locker 300, when the support member 200 is rotated with respect to the center of the cover body 100 by rotating the cover body 100, the connection post 130 of the cover body 100 is also rotated with respect to the center of the support member 200, and since the connection hole 230 has an arc shape, the connection post 130 can relatively slide in the connection hole 230. In addition, after the locking member 300 is removed, when the cover body 100 is rotated, the supporting member 200 can rotate relative to the connecting column 130 through the connecting hole 230, that is, eccentrically rotate relative to the cover body 100, thereby driving the two limiting columns 110 to deflect in the deflecting groove 215. In this embodiment, the center of symmetry of the two offset slots 215 may be offset from the center post 150, for example, by locating the center of symmetry at the location of the connecting post 130, thereby facilitating the offset of the restraint post 110 within the offset slots 215.

It should be understood that the cooperation of the guide groove 210 and the offset groove 215 with the position-limiting post 110 plays a guiding auxiliary role for the central rotation and the eccentric rotation of the supporting member 200 with respect to the lid body 100 when the lid cover 400 is disassembled, thereby assisting the disassembly separation of the supporting member 200 from the lid body 100.

Further, fig. 1 and 3 also show the sliding track range of the connection post 130 and the position-limiting post 110 when the supporting member 200 rotates relative to the center of the cover body 100 in the locked state, and the rotation angles thereof are all rotation angles along y-y to x-x. When the locking member 300 is removed and the supporting member 200 eccentrically rotates with respect to the connecting post 130 of the cover 100, the central post 150 is offset with respect to the central hole 250, the positioning posts 110 are offset with respect to the offset slots 215, the offset tracks are as shown in fig. 5, the rotation angle is along the rotation from x-x to z-z, the offset tracks of the two positioning posts 110 in the offset slots 215 are different, and it can be seen from fig. 5 that the offset track of the positioning post 110 farther from the central hole 230 in the offset slot 215 is longer.

Here, the rotation angles and the sliding tracks of the spacing post 110 and the connecting post 130 can be adjusted by a gear assembly, and the rotation angles of the spacing post and the connecting post can be set to be the same or different, which is not listed here.
