The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0026] In order to solve the problem of poor nut fastening reliability of the stirring device in the prior art, the utility model provides a cooking utensil stirring device and a cooking utensil, wherein the cooking utensil comprises the following cooking utensil stirring device.

[0027] Figures 1 to 5The cooking utensil stirring device comprises a stirring piece 10, a seat body 20, a fastener 30, and an anti-loosening piece 40. The seat body 20 is used to install the stirring piece 10. The fastener 30 is connected to the seat body 20 and fixes the stirring piece 10 to the seat body 20, and the fastener 30 can rotate in a first direction relative to the seat body 20, and the first direction is the unlocking direction of the fastener 30. The anti-loosening piece 40 is connected to the seat body 20 and abuts against the fastener 30. The anti-loosening piece 40 can rotate in a second direction relative to the seat body 20, and the second direction is the unlocking direction of the anti-loosening piece 40. The first direction is opposite to the second direction, and the anti-loosening piece 40 prevents the fastener 30 from rotating in the first direction to unlock.

[0028] In this embodiment, a fastener 30 and an anti-loosening member 40 are provided to be connected to the seat body 20, and the locking rotation directions of the fastener 30 and the anti-loosening member 40 are opposite, so that the anti-loosening member 40 can prevent the fastener 30 from loosening. When the fastener 30 tends to loosen, the fastener 30 rotates in the first direction to unlock itself, and because the unlocking rotation direction of the anti-loosening member 40 is the second direction, the rotation of the fastener 30 in the first direction is stopped by the anti-loosening member 40, and the rotation trend of the fastener 30 in the second direction further locks the anti-loosening member 40, thereby further enhancing the anti-loosening effect of the anti-loosening member 40, thereby ensuring that the fastener 30 is firmly locked on the seat body 20. At the same time, in addition to the effect of the anti-loosening member 40 on the fastener 30, when the anti-loosening member 40 becomes loose, since the anti-loosening member 40 rotates in the second direction when it is unlocked, the anti-loosening member 40 further tightens the fastener 30, so that the fastener 30 and the anti-loosening member 40 have an interlocking effect, thereby further improving the anti-loosening effect between the fastener 30 and the seat body 20. In addition, the solution of this embodiment has a simple structure, low cost, and is easy to disassemble and assemble.

[0029] It should be noted that the first direction in this embodiment refers to the counterclockwise direction, and the second direction refers to the clockwise direction. The first direction and the second direction can also be interchanged as long as the connection relationship between the fastener 30, the anti-loosening member 40 and the seat body 20 is satisfied.

[0030] In this embodiment, the fastener 30 and the anti-loosening member 40 are matched with the seat body 20 in a threaded manner, that is, there is a first thread structure between the fastener 30 and the seat body 20, and there is a second thread structure between the anti-loosening member 40 and the seat body 20. The rotation direction of the first thread structure is opposite to the rotation direction of the second thread structure. Specifically, Figure 1As shown, in this embodiment, the stirring member 10 is arranged between the seat body 20 and the fastener 30, the fastener 30 is connected to the seat body 20 through the first thread structure, and the fastener 30 is close to and abuts against the stirring member 10 when tightened in the second direction, so that the fastener 30 is difficult to loosen relative to the seat body 20 in the second direction, and the anti-loosening member 40 is connected to the seat body 20 through the second thread structure, and the anti-loosening member 40 is close to and abuts against the fastener 30 when tightened in the first direction, so that the anti-loosening member 40 is difficult to loosen relative to the seat body 20 in the first direction. When the fastener 30 tends to loosen, the rotation of the fastener 30 in the first direction also drives the anti-loosening member 40 abutting against it to rotate in the first direction. The anti-loosening member 40 has a thread rotation direction opposite to that of the fastener 30. When the anti-loosening member 40 rotates in the first direction, it approaches the fastener 30 to prevent the fastener 30 from separating from the seat body 20, thereby preventing the fastener 30 from loosening. In addition, the threaded connection method makes it possible to adjust the tightness of the fastener 30 more precisely, thereby reducing the gaps for hiding dirt.

[0031] In this embodiment, the base 20 has a boss 21, the boss 21 passes through the stirring member 10, and the fastener 30 and the anti-loosening member 40 are both threadedly engaged with the boss 21. In other words, the stirring member 10 has a hole for the boss 21 to pass through, and the boss 21 passes through the hole and is threadedly engaged with the fastener 30 and the anti-loosening member 40, thereby fixing the stirring member 10 between the base 20 and the fastener 30. When the stirring member 10 needs to be replaced or disassembled, it is only necessary to rotate the anti-loosening member 40 in the second direction and the fastener 30 in the first direction in sequence, so that the stirring member 10 can be removed from the base 20, thereby replacing a new stirring member 10.

[0032] In this embodiment, the outer peripheral side of the convex post 21 has a first thread 211, and the convex post 21 further has a through hole axially provided. The inner wall of the through hole has a second thread 212. The helix directions of the first thread 211 and the second thread 212 are opposite. One of the fastener 30 and the anti-loosening member 40 is in threaded engagement with the first thread 211, and the other of the fastener 30 and the anti-loosening member 40 is in threaded engagement with the second thread 212. In this embodiment, the fastener 30 uses a nut. The fastener 30 is arranged on the outer peripheral side of the convex post 21 and is engaged with the first thread 211, so as to fix the stirring member 10 to the seat body 20. The anti-loosening member 40 uses a bolt. The threaded part of the anti-loosening member 40 is arranged in the through hole and is engaged with the second thread 212. The anti-loosening member 40 abuts against the side of the fastener 30 away from the stirring member 10, so as to lock the fastener 30 and the stirring member 10. This setting method has a simple structure and only needs to process left- and right-handed threads, with a relatively low cost. Of course, it is also possible to use the method of tightening the fastener 30 in cooperation with the second thread 212 and tightening the anti-loosening member 40 in cooperation with the fastener 30 to achieve locking. For example, the fastener 30 is set in a "C" shape. The first side of the opening has a thread extending axially so that it can be inserted into the through hole and tightened in cooperation with the second thread 212. The second side relative to the first side is located outside the convex post 21 and can abut against the surface of the stirring member 10 away from the seat body 20, so as to fix the stirring member 10. The second side of the opening also has a reverse thread extending axially and cooperating with the anti-loosening member 40. The anti-loosening member 40 uses a nut. The surface of the anti-loosening member 40 close to the stirring member 10 abuts against the surface of the stirring member 10 after being tightened. In this way, when one of the fastener 30 and the anti-loosening member 40 has a loosening tendency, torque is transmitted to the other through the stirring member 10, causing the other to have a tightening movement tendency, thereby achieving interlocking.

[0033] In this embodiment, the fastener 30 has a threaded hole 31, and the threaded hole 31 has a fastening internal thread that is threadedly matched with the first thread 211. The anti-loosening member 40 has a head 41 and a threaded portion 42. The threaded portion 42 is cylindrical, penetrates the threaded hole 31 and has an anti-loosening external thread that is threadedly matched with the second thread 212. The head 41 abuts against the fastener 30 and can prevent the fastener 30 from axial movement. Specifically, when the fastener 30 is tightened on the boss 21, the boss 21 enters the threaded hole 31 of the fastener 30, and the anti-loosening member 40 passes through the threaded hole 31 from the end of the fastener 30 away from the stirring member 10 and is screwed into the through hole of the boss 21. In order to ensure that the anti-loosening member 40 will not be completely screwed into the threaded hole 31, the head 41 of the anti-loosening member 40 is set to a cylindrical or arc shape in this embodiment, and its diameter is greater than the diameter of the threaded hole 31, so as to ensure the blocking effect of the head 41 on the fastener 30. At the same time, in order to ensure the friction between the anti-loosening member 40 and the fastener 30, the surface of the anti-loosening member 40 abutting against the fastener 30 is a plane to ensure a larger contact area, thereby generating a larger friction. In this way, when one of the anti-loosening member 40 and the fastener 30 rotates in the direction of the loosening trend, it can drive the other to rotate in the same direction. Since the thread rotation direction is opposite, the other has a tendency to tighten the thread, thereby achieving interlocking. The head 41 of the anti-loosening member 40 can be set to a hexagonal shape to facilitate the use of tools for disassembly and assembly. Of course, the specific shape of the head 41 can also be adjusted as needed, as long as it can abut against the fastener 30 to achieve blocking of the axial movement of the fastener 30.

[0034] like Figure 2As shown, in this embodiment, the fastener 30 has an axially arranged fastening section 32 and a transition head 33, and the transition head 33 is farther away from the seat body 20 than the fastening section 32, and the threaded hole 31 includes a threaded section located at the fastening section 32 and a transition section located at the transition head 33, and the threaded section has a fastening internal thread, that is, the part of the fastener 30 that abuts against the stirring member 10 is the fastening section 32, and the part that abuts against the anti-loosening member 40 is the transition head 33, and the threaded hole 31 inside the fastening section 32 cooperates with the first thread 211 to play a fastening role, the boss 21 is located in the threaded section, and the anti-loosening member 40 passes through the transition section and is tightened with the second thread 212 of the boss 21 to play an anti-loosening role. The outer peripheral side of the fastening section 32 is a hexagonal mounting structure, which is convenient for disassembly and assembly using tools. The end of the fastening section 32 close to the stirring member 10, that is, the surface abutting the stirring member 10, is a plane to ensure a larger contact area with the stirring member 10, and the end away from the stirring member 10 is connected to the transition section. The interior of the transition section may be a threaded hole or a through hole. The transition section is connected to the threaded hole 31 of the fastening section 32. The outer peripheral surface of the transition section is an arc-shaped surface to avoid the installation position of the anti-loosening member 40. The surface of the transition section away from the fastening section 32 abuts against the anti-loosening member 40. This structure in which the threads are fully tightened and the contact surfaces abut against each other makes there is no gap between the anti-loosening member 40, the fastener 30, and the stirring member 10, reducing the possibility of hiding dirt.

[0035] In order to prevent the head 41 from falling into the threaded hole 31 when the anti-loosening member 40 is screwed into the through hole, so that the anti-loosening member 40 and the fastener 30 cannot abut against each other, or the abutting area is too small to affect the anti-loosening effect, the inner diameter of the transition section is set to be less than or equal to the inner diameter of the threaded section in this embodiment, and the head 41 abuts against the transition head 33. Preferably, the surface of the transition head 33 abutting against the anti-loosening member 40 is a plane to increase the contact area with the anti-loosening member 40 and increase the friction force.

[0036] like Figures 3 to 5 As shown, preferably, the rotation axis of the anti-loosening member 40 is eccentrically arranged relative to the rotation axis of the fastener 30, and the boss 21 has an eccentrically arranged through hole, that is, the through hole on the boss 21 is eccentrically arranged relative to the geometric axis of the boss 21, and the rotation axis of the fastener 30 is consistent with the geometric axis of the boss 21. Since the anti-loosening member 40 is screwed into the through hole, the rotation axis of the anti-loosening member 40 is located at the geometric axis of the through hole. In this way, when one of the anti-loosening member 40 and the fastener 30 has a tendency to loosen in the direction away from the stirring member 10, the rotation axes thereof are inconsistent, so that a certain eccentric torque is formed between the anti-loosening member 40 and the fastener 30, thereby reducing the possibility of the anti-loosening member 40 being loosened by the fastener 30.

[0037] In this embodiment, the minimum inner diameter of the threaded hole 31 is greater than or equal to the maximum distance from the inner wall of the through hole to the rotation axis of the fastener 30. Specifically, the minimum inner diameter of the threaded hole 31 is also the inner diameter of the transition section, and the rotation axis of the fastener 30 is also the geometric axis of the boss 21. The distance from the inner wall of the through hole to the rotation axis of the fastener 30 determines the position of the through hole on the surface of the fastener 30 perpendicular to the axis. By adopting the above-mentioned arrangement, when the fastener 30 is screwed into the boss 21, no matter to which position the transition section rotates, the through hole is always completely located within the range of the transition section, so that the through hole will not be blocked by the solid part of the transition head 33, and the anti-loosening member 40 can be smoothly screwed into the through hole.

[0038] It should be noted that, the multiple in the above embodiments refers to at least two.

[0039] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0040] 1. Solve the problem of poor nut fastening reliability of the stirring device in the prior art;

[0041] 2. The fastener and the anti-loosening member are connected to the seat body, and the seat body is locked from two opposite directions, so that the fastener and the anti-loosening member are interlocked, thereby achieving the anti-loosening effect between the fastener and the seat body;

[0042] 3. The structure is simple and low-cost, easy to disassemble and assemble, and reduces the gaps that hide dirt.
