In order to solve the problem that the cooking utensil has the difficult assembly of clip among the prior art, the utility model provides a clip structure and cooking utensil.

As shown in fig. 1 to 8, the clasp structure comprises a clasp body 20 and a movement guiding structure 30, wherein the clasp body 20 has a guiding surface 21, an extending direction of the guiding surface 21 and a moving direction of the clasp structure 10 form an included angle and are not perpendicular, the guiding surface 21 includes a plurality of surface segments connected in sequence along the extending direction, all the surface segments are not located in the same plane, and the movement guiding structure 30 is disposed on the clasp body 20 and extends along the moving direction of the clasp structure 10.

By arranging the movement guide structure 30 on the clasp structure 10, the movement direction of the clasp structure 10 is limited in the extending direction of the movement guide structure 30, and the movement of the clasp structure 10 is no longer a rotating movement, so that the clasp structure 10 is easily installed on a structure to be installed, and the convenience of assembling the clasp structure 10 is improved. The guiding surface 21 guides the structure matched with the hook structure 10, and the structure matched with the hook structure 10 can drive the hook structure 10 to move through the guiding surface 21. The surface sections of the guiding surface 21 are not in the same plane, so that the structure cooperating with the hook structure 10 will drive the hook structure 10 to move along the extending direction of the movement guiding structure 30 when moving along the guiding surface 21.

As shown in fig. 8, an end of the hook body 20 away from the fastening end 26 has a guiding rib 22 protruding upward, a side surface of the guiding rib 22 facing the fastening end 26 of the hook body 20 is used as a guiding surface 21, and a connecting line between the fastening end 26 and the guiding rib 22 is used as a moving direction of the hook structure 10. That is, the direction of movement of clasp 10 is parallel to the direction of the horizontal connection between clasped end 26 and guide rib 22. The guide ribs 22 are provided to facilitate movement of the clasp 10 by structure associated with the clasp 10.

As shown in fig. 8, the distances between the plurality of surface segments and the fastening end 26 of the hook body 20 gradually increase along the extending direction of the guiding surface 21. This arrangement allows the structure associated with clasp 10 to move along guide surface 21, which also drives clasp 10 in the direction of the horizontal line between clasp end 26 and guide rib 22.

As shown in fig. 8, the clasp body 20 includes a top plate 23, and lateral vertical plates 24 located on two sides of the top plate 23 and disposed oppositely, and at least a portion of the movement guide 30 is disposed on the lateral vertical plates 24 of the clasp body 20. The arrangement enables the height occupied by the hook structure 10 to be smaller, which is beneficial to the miniaturization requirement of the hook structure 10 and the miniaturization requirement of the upper cover component. And the lateral riser 24 may strengthen the clasp 10 such that the clasp 10 is not easily damaged.

Alternatively, the clasp body 20 and the motion guide 30 are integrally formed, so that the clasp 10 is structurally strong.

As shown in fig. 8, the hook body 20 further includes a fastening protrusion 25, the fastening protrusion 25 is located at the fastening end 26 of the hook body 20 and extends out toward a direction away from the guide surface 21, and at least another portion of the movement guide 30 is disposed at two sides of the fastening protrusion 25. That is, the engaging protrusion 25 extends away from the guiding surface 21 to cooperate with the engaging portion 51 of the pot body assembly 50 to engage and disengage the hook structure 10. While the other part of the movement guide 30 is disposed on both sides of the engaging protrusion 25 to make the movement of the hook structure 10 more stable. Through set up motion guide structure 30 in a plurality of positions of clasp body 20, can increase clasp body 20 and wait the area of contact between the mounted position (for example the inside lining) to guarantee the effect of motion direction, avoid clasp structure 10 to topple or block dead at the in-process of motion, improved clasp structure 10's motion stability.

Optionally, the motion guide structure 30 is a limit rib. The limiting ribs may cooperate with the grooves to limit the movement of the clasp 10, making the movement of the clasp 10 more reliable, and in addition, the limiting ribs may also enable the clasp 10 to be supported on a structure (e.g., a liner). Of course, the motion guide structure 30 may also be a groove. At this moment, the rib position matched with the groove is correspondingly arranged at the position to be installed.

As shown in fig. 8, the top plate 23 has a limiting hole 231, and the extending direction of the limiting hole 231 is the same as the moving direction of the hook structure 10. The limiting hole 231 can limit the movement distance of the hook structure 10, so that the movement of the hook structure 10 is more reliable. Of course, a limiting groove may be formed on the top plate section 23 to function as the limiting hole 231.

As shown in fig. 8, the plurality of surface segments include a first surface segment 211, a second surface segment 212 and a third surface segment 213 which are connected in sequence, the second surface segment 212 is used as a transition surface, the second surface segment 212 is a plane or an arc surface, and the connection between the second surface segment 212 and the first surface segment 211 and the third surface segment 213 is smoothly transited. The smooth transition of the junction of the second surface segment 212 and the first surface segment 211 and the third surface segment 213 is to avoid the problem that the structure matched with the clasp structure 10 is jammed when moving along the guide surface 21, and the smooth transition is not easy to cause the jam condition, so that the stability of the movement of the clasp structure 10 is increased. And the first face section 211 and the third face section 213 can be matched with each other by the following methods:

first, the first surface segment 211 and the third surface segment 213 are planar and parallel, the first surface segment 211 and the third surface segment 213 are not in the same plane, and are staggered, and the second surface segment 212 connects the first surface segment 211 and the third surface segment 213. This arrangement allows the structure cooperating with the hook structure 10 to move along the guide surface 21 and also to move the hook structure 10 along the extension direction of the movement guide 30.

Second, the first surface segment 211 and the third surface segment 213 are planar and non-parallel, and the first surface segment 211 and the third surface segment 213 are both perpendicular to the moving direction of the hook structure 10 with an included angle therebetween.

Third, at least one of the first face section 211 and the third face section 213 is a cambered surface. The cambered surface is convenient for realizing smooth transition among all surface sections.

Fourth, the first surface segment 211 and the third surface segment 213 are both arc surfaces and have the same radian.

Fifth, the first surface segment 211 and the third surface segment 213 are both arc surfaces and have different radians.

The latter combinations are similar to the first resulting effect and will not be described in detail here.

As shown in fig. 1, the cooking utensil includes an upper cover assembly 40 and a pot body assembly 50, the upper cover assembly 40 is covered on the pot body assembly 50 in an openable and closable manner, the upper cover assembly 40 includes the above-mentioned clasp structure 10, the pot body assembly 50 has a buckle position 51 matched with the clasp structure 10, the upper cover assembly 40 further includes a handle rotating assembly 41, the handle rotating assembly 41 is rotatably disposed on a liner 42 of the upper cover assembly 40, and a driving end 412 of the handle rotating assembly 41 drives the clasp structure 10 to move.

The opening and closing between the upper cover assembly 40 and the pot body assembly 50 are realized by the cooperation of the fastening positions 51 and the fastening teeth 25 of the clasp structure 10. When the fastening protrusion 25 is fastened with the fastening portion 51, the upper cover assembly 40 is fastened with the pot body assembly 50. When the fastening protrusion 25 is separated from the fastening position 51, the upper cover assembly 40 is separated from the pot body assembly 50. The driving end 412 of the handle rotating member 41 is engaged with the guiding surface 21 of the hook structure 10 to drive the hook structure 10 to move, so as to engage the engaging protrusion 25 with the engaging portion 51. Since the clasp 10 moves on the liner 42 in a translational manner, rather than in a rotational manner, the internal space of the lid assembly 40 occupied by the clasp 10 can be reduced, and the lid assembly 40 can be made thinner.

As shown in fig. 6, the lining 42 has at least one guiding post 421, the guiding post 421 extends into the limiting hole 231 or the limiting groove of the hook structure 10 and slides in the limiting hole 231 or the limiting groove to limit the sliding distance of the hook structure 10 on the lining 42, and the guiding posts 421 are disposed corresponding to the limiting holes 231 one by one. The cooperation of guide column 421 and spacing hole 231 makes clasp structure 10 only can slide fixed distance for clasp structure 10's motion becomes controllable, avoids clasp structure 10 and detain position 51 and detain the phenomenon that dies and can not open to appear, still can avoid clasp structure 10's motion off tracking, also plays certain guard action to clasp structure 10 simultaneously. The guide posts 421 are provided to ensure that the clasp 10 does not disengage from the liner 42. In this embodiment, the liner 42 is provided with two guiding studs 421, and there are two limiting holes 231 engaged with the guiding studs 421.

As shown in fig. 3 to 5, the liner 42 further has a height-limiting structure, which includes a stopper 422 and a fastener 423, the stopper 422 is crimped on the liner 42 and the clasp 10, and the fastener 423 fastens the stopper 422 on the liner 42 to stop the upward movement of the clasp 10. The stopper 422 is pressed partially against the lining 42 and partially against the hook structure 10, so as to prevent the hook structure 10 from moving upward, thereby preventing the hook structure 10 from separating from the lining 42 in the process of being stressed, and improving the motion stability of the hook structure 10. Fasteners 423 mount the stop 422 on the liner 42 to prevent failure of the stop 422.

Specifically, the fastener 423 is a screw and the stopper 422 is a washer. Of course, the height limiting structure may be formed by one component, such as a large head screw.

Example one

As shown in fig. 7, the handle rotation assembly 41 includes a rotation rod 411, an extended end of the rotation rod 411 has a driving end 412, the driving end 412 has a top contact surface 413, and during the rotation of the rotation rod 411, the top contact surface 413 slides along the guide surface 21, the top contact surface 413 is an arc-shaped surface, and the curvature center of the arc-shaped surface is on one side of the top contact surface 413 close to the buckle position 51. The abutting surface 413 drives the hook structure 10 to move away from the fastening position 51, so as to disengage the fastening protrusion 25 from the fastening position 51. In this embodiment, the driving end 412 is a protrusion formed at the end of the outward extending end of the rotating rod, and the abutting surface 413 is a surface of the protrusion on a side far away from the fastening position 51. It should be noted that, it is necessary to ensure proper contact friction between the guide surface 21 and the abutting surface 413, so as to avoid excessive or insufficient friction, resulting in loss of force or operational slippage, thereby affecting operational feel and motion reliability.

Through the cooperation of the top contact surface 413 and the hook structure 10, the rotational motion of the rotating rod 411 is converted into the translational motion of the hook structure 10, so that the motion reversing is realized, and the smooth locking and unlocking process and good operation hand feeling are ensured.

In the embodiment shown in fig. 5, the handle 414 of the handle rotating assembly 41 is separated from the rotating rod 411, and the rotating rod 411 passes through the cover and is connected to the handle 414, so that the handle 414 drives the rotating rod 411 to move when rotating.

Specifically, the upper cover assembly 40 further has a reset member 43, the reset member 43 is supported between the hook structure 10 and the lining 42, and the reset member 43 keeps the hook structure 10 and the fastening position 51 in a fastening state. When the handle rotating assembly 41 is switched from the locking position to the unlocking position, the handle rotating assembly 41 drives the clasp 10 to move in a translational manner so that the clasp 10 overcomes the action of the reset piece 43 and is separated from the catch 51, and when the handle rotating assembly 41 is switched from the unlocking position to the locking position, the reset piece 43 pushes the clasp 10 to reset under the action of the reset force so as to be buckled with the catch 51.

In this embodiment, when the handle rotating assembly 41 is switched from the locking position to the unlocking position, the abutting surface 413 moves along the guiding surface 21 when the handle rotating assembly 41 rotates, and moves from the surface section of the guiding surface 21 far away from the fastening end 26 to the surface section near the fastening end 26. At this time, the handle rotating assembly 41 drives the hook structure 10 to move in a translational manner in a direction away from the fastening position 51, so as to separate the hook structure 10 from the fastening position 51, and unlock the upper cover assembly 40 and the cooker body assembly 50. In this process, the handle rotating assembly 41 always pulls the clasp 10 inward, and work needs to be done against the force of the restoring member 43.

Optionally, the cooking appliance is an electric pressure cooker. Of course, the cooking appliance may also be other electric products for cooking food materials, such as an electric cooker and the like.

Example two

The difference from the first embodiment is that the handle rotating assembly 41 and the reset member 43 function just in reverse to the first embodiment. Specifically, the handle rotating assembly 41 enables the hook structure 10 to be buckled with the buckling position 51, the reset piece 43 enables the hook structure 10 to be kept separated from the buckling position 51, and the reset piece 43 is located far away from the center of the upper cover assembly 40 relative to the hook structure 10.

In the present embodiment, the guide surface is the surface of the guide rib 22 away from the fastening end 26 of the clip body 20 as the guide surface 21.

Note that the return spring of the return member 43.

Specifically, the reset member 43 keeps the hook structure 10 separated from the catch 51, when the handle rotating member 41 is switched from the unlocking position to the locking position, the handle rotating member 41 drives the hook structure 10 to move in a translational manner so that the hook structure 10 overcomes the action of the reset member 43 and is buckled with the catch 51, and when the handle rotating member 41 is switched from the locking position to the unlocking position, the reset member 43 pushes the hook structure 10 to reset so that the hook structure 10 is separated from the catch 51. When the handle rotating component 41 is switched from the unlocking position to the locking position, the handle rotating component 41 pushes the hook structure 10 to move in a translational manner in a direction away from the center of the upper cover component in the rotating process, so that the hook structure 10 overcomes the action of the reset piece 43 and is buckled with the buckling position. When the handle rotating element 41 is switched from the locking position to the unlocking position, the pushing force of the handle rotating element 41 on the clasp mechanism 10 is reduced, and under the action of the resetting element 43, the clasp mechanism 10 is pushed to the central side of the pot body element 50 by the resetting element 43, so that the clasp mechanism 10 is separated from the buckle position 51, and the upper cover assembly 40 is unlocked from the pot body element 50.

EXAMPLE III

The difference from the first embodiment is that the engagement and disengagement of the hook structure 10 and the fastening position 51 are realized by the handle rotating component 41 without the action of the reset piece 43.

Specifically, the handle rotating assembly 41 and the clasp structure 10 are always connected, and when the handle rotating assembly 41 moves, the clasp structure 10 moves back and forth in a translational manner under the action of the handle rotating assembly 41. When the handle rotating element 41 is switched from the unlocking position to the locking position, the handle rotating element 41 drives the hook structure 10 to move in a translational manner in a direction close to the hook 51 during the rotation process, so that the hook structure 10 is buckled with the hook 51. When the handle rotating assembly 41 is switched from the locking position to the unlocking position, the handle rotating assembly 41 drives the hook structure 10 to move in a translational manner in a direction away from the hook 51 during the rotation process, so that the hook structure 10 is separated from the hook 51.

Specifically, a slot may be formed at the driving end 412 of the rotating rod 411, so that at least a portion of the hook structure 10, for example, the top of the hook structure 10, is inserted into the slot, so that during the rotation of the rotating rod 411, the hook structure 10 is always in contact with the slot, so that the hook structure 10 is pushed forward or pulled backward according to the specific movement of the handle rotating component 41, and thus the unlocking and the locking are realized.
