Detailed Description

The invention is further described with reference to the following figures and examples:

the first embodiment is as follows: referring to fig. 2 to 6, the slow cooker with a locking structure comprises a cooker body, a cooker cover and handles arranged on two sides of the cooker body, wherein each handle is provided with a locking structure, each locking structure comprises a retaining ring 11 arranged on the handle and a clasp 12 arranged on the cooker cover, one side of the retaining ring 11 is an open end, and the other side of the retaining ring is a closed end in snap fit with the clasp 12; the handle include with the fixed part 13 that the pot body is connected to and the folding portion 15 of being connected through pivot 14 with this fixed part 13, be equipped with a cam mechanism 16 on the pivot 14 of folding portion 15, the open end of buckle 11 sets up on this cam mechanism 16's follower for have locking and unblock two states between buckle 11 and clasp 12.

In this embodiment, the retaining ring 11 is formed by bending a steel wire, and the open ends thereof are respectively provided with outward hooks to form a rotating shaft for rotatably connecting the retaining ring 11 with the driven member.

As shown in fig. 2, the folding portion 15 is U-shaped, the opening end of the folding portion is connected to the fixing portion 13 through the rotating shaft 14, a cavity for accommodating the opening end of the folding portion 15 is disposed in the fixing portion 13, the bottom of the cavity is open, the folding portion 15 rotates to the bottom through the rotating shaft 14, and has a rotational degree of freedom from horizontal to vertical downward, when the folding portion 15 rotates to vertical downward, as shown in fig. 4, corresponding to the unlocking state of the buckle 11 and the clasp 12, and when the folding portion 15 rotates to horizontal, corresponding to the locking state of the buckle 11 and the clasp 12.

As shown in fig. 3, 5 and 6, the cam mechanism 16 is a disc cam mechanism, and includes a cam 17, and a mounting post 18 and a through hole 19 that are disposed on the cam 17, the open end of the buckle 11 is rotatably connected to the mounting post 18, and the cam 17 is connected to the folding portion 15 through the through hole 19 by a screw 20. The cam 17 is in a fan shape, the shaft rotation 14 is located at the center of the fan shape, and the mounting column 18 and the through hole 19 are located at two ends of the fan shape arc respectively. When the folding portion 15 rotates downward, the screw 20 drives the cam 17 to rotate counterclockwise together, so that the mounting post 18 located below rotates counterclockwise to reach the upper side of the screw 20, the distance from the mounting post 18 to the pot cover is shortened, and the retaining ring 11 can be loosened from the clasp 12, as shown in fig. 3, and is in an unlocking state.

When needing to lock, place buckle 11 on clip 12, be the active state this moment, not locking, then upwards overturn folding portion 15, cam 17 is under folding portion 15's pulling, clockwise rotation, and erection column 18 stimulates buckle 11 downwards, until folding portion 15 resumes horizontal position, buckle 11 and clip 12 are taut, realize the locking to the pot cover to oppress the sealing washer between pot cover and the pot body, form sealed lid and close, avoid overflowing of hot water.

In order to avoid the mistaken turning of the folding portion 15, the fixing portion 13 is close to the rotating shaft 14 and is provided with an arc-shaped limiting sliding groove 21 which is coaxial with the rotating shaft 14, the folding portion 15 is provided with a pin shaft 22, and the pin shaft 22 is slidably connected in the arc-shaped limiting sliding groove 21. The handle is folded, a certain rotating force needs to be applied to the folding part 15, so that the pin 22 can move in the arc-shaped limiting sliding groove 21, otherwise, the handle cannot be folded, and the handle is prevented from being loosened by mistake between the buckle 11 and the clasp 12 caused by external force. Further, a convex point can be arranged in the arc-shaped limiting sliding groove 21 to increase the sliding resistance of the pin 22, and the convex point can be arranged at the position (not shown) where the pin 22 is located in the locking state.

A pushing and poking member (not shown) may be further disposed on the folding portion 15 or the cam 17, the retaining ring 11 is placed on the pushing and poking member, and when the folding portion 15 rotates to the horizontal state, the pushing and poking member pushes the retaining ring 11 to rotate towards the clasp 12. Therefore, the manual pushing and poking of the buckle 11 can be omitted, and when the folding part 15 or the cam 17 rotates, the pushing and poking piece automatically pushes the buckle 11 to rotate towards the clasp 12, and meanwhile, the operation of locking and buckling is completed.

The pushing and pulling piece can also be a connecting rod, the connecting rod is connected between the cam 17 and the snap ring 11, the snap ring 11 can be pushed to rotate and lock the clasp 12 during locking, the snap ring 11 can be pulled to separate from the clasp 12 during unlocking, manual operation is simplified, and a user can obtain better user experience.

Example two: referring to fig. 7 to 9, the slow cooker with a locking structure of the embodiment is basically similar to the first embodiment, except that: a safety lock 23 is arranged in the folding portion 15, the safety lock 23 comprises a support 24, a spring 25 and a key 26, a lock hole 27 is arranged at the front end of the support 24, a lock tongue (not shown) matched with the lock hole 27 is arranged in the fixing portion 13, a pressing piece 28 is arranged in the middle of the support 24, one end of the spring 25 abuts against the pressing piece 28, the other end abuts against the key 26, and the key 26 protrudes out of the outer surface of the folding portion 15.

In this embodiment, the cooperation between the clasp 11 and the clasp 12 is the same as that in the first embodiment, but the difference is the safety lock 23 for preventing false turning, as shown in fig. 9, the front end of the bracket 24 is provided with a lock hole 27, which is engaged with the lock tongue in the fixing part 13, so that the folding part 15 cannot rotate in a locked state, and the problem of preventing false unlocking is solved; when unlocking is needed, the key 26 is pressed, the key 26 pushes the pressing piece 28 through the spring 25, the support 24 moves outwards, the locking of the lock tongue is released, the folding part 15 can be rotated at the moment, the locking state of the buckle 11 and the buckle 12 is released, the support 24 resets under the elastic force of the spring 25, when locking is needed again, the folding part 15 is rotated, then the key 26 is pressed, and the lock hole 27 in the support 24 is matched with the lock tongue again to enter the locking state.
