[0037] In one aspect of the present invention, a stirring mechanism based on a cooking device is provided, the stirring mechanism comprising a fastener 10, a main shaft 20 and a stirring portion 30. Specifically, as Figure 1As shown, the stirring part 30 is connected to the main shaft 20 , and the fastener 10 is connected to the main shaft 20 and is arranged on the upper part of the stirring part for locking the stirring part 30 .

[0038] Another aspect of the utility model provides a push-pull locking structure based on a cooking device, comprising a main shaft and a fastener threadedly sleeved on the main shaft, and the push-pull locking structure also includes a locking assembly. The locking assembly includes a locking clamp ring and a locking pin; wherein the locking clamp ring is sleeved on the main shaft and abuts against the main shaft circumferentially to limit the position; the locking pin is constrained in the locking clamp ring along the radial sliding direction of the locking clamp ring; a locking groove is opened on the fastener along the circumferential direction, and when the fastener is in the locking position, the locking pin is slidably inserted into the locking groove.

[0039] The push-pull locking structure based on the cooking device has a reliable locking function and is very safe to lock during use, which effectively solves the problem that the fasteners of the stirring mechanism of the cooking device are prone to loosening. At the same time, the push-pull locking structure is simple in structure and easy to install and maintain.

[0040] like Figures 2 to 6 As shown, the push-pull locking structure based on the cooking device includes a fastener 10, a spindle 20 and a locking assembly. Specifically, as Figure 2 As shown, a locking groove 11 is provided on the upper edge of the fastener 10 in the circumferential direction, and an internal thread is provided in the inner cavity of the fastener 10, and the fastener 10 is threadedly connected to the main shaft 20. Figure 2 As shown, the inner side of the fastener 10 is provided with an internal thread, and the fastener 10 is connected to the spindle 20 by a thread. A locking groove 11 is provided at the outer edge of the lower part of the fastener 10 near the port. Preferably, the locking groove 11 is annular. Specifically, as Figures 4 to 6 As shown, the other end of the locking pin 70 away from the main shaft 20 passes through the locking clamp ring, and a bent handle is fixedly provided on the other end, and the locking pin 70 is slidably inserted into the annular locking groove. Preferably, the fastener 10 is a locking nut, and an annular locking groove is provided at the outer edge of the lower part of the locking nut near the port. A vertical offset is provided on the main shaft 20 for abutting against related components.

[0041] In some embodiments of the present invention, a locking fold is provided on the fastener 10 in the circumferential direction, and the locking pin 70 abuts against the upper edge of the locking fold, thereby preventing the fastener 10 from sliding axially along the main shaft 20 .

[0042] The locking assembly includes an upper locking snap ring 40 and a lower locking snap ring 50, wherein the upper locking snap ring 40 is connected to the upper portion of the lower locking snap ring 50. Figure 3As shown, the upper locking snap ring 40 is provided with a cavity 41 and a groove 42, and the upper locking snap ring 40 is also provided with a plurality of connecting holes. An elastic component is provided in the cavity, and the elastic component applies an elastic force to the locking latch 70 toward the spindle 20. When the locking latch 70 is in the locking position, the handle of the locking latch 70 is engaged in the groove 42, thereby preventing the locking latch 70 from loosening, and further limiting the fastener 10 from sliding in the axial direction of the spindle 20. Specifically, as shown in FIG. Figure 4 As shown, the inner cavity of the lower locking snap ring 50 is provided with a flat surface 51; a through hole is provided in the middle of the flat surface 51, and the shape of the through hole is non-circular, and the through hole matches the outer dimensions of the offset position on the main shaft 20. When the through hole of the lower locking snap ring 50 is sleeved on the offset position of the main shaft 20, the end surface of the flat surface 51 of the lower locking snap ring 50 abuts against the offset position, thereby preventing the flat surface 51 and the main shaft 20 from rotating relative to each other.

[0043] like Figure 5 As shown, the inner diameter of the upper locking snap ring 40 is the same as the inner diameter of the lower locking snap ring 50, and the inner diameters of the upper locking snap ring 40 and the lower locking snap ring 50 are larger than the outer diameter of the lower portion of the fastener 10; the inner diameters of the upper locking snap ring 40 and the lower locking snap ring 50 are preferably the same as the outer diameter of the lower portion of the fastener 10. This design can not only make the lower outer surface of the fastener 10 fit well with the inner side surfaces of the upper locking snap ring 40 and the lower locking snap ring 50, but also reduce the volume space of the locking structure. When the upper locking snap ring 40 and the lower locking snap ring 50 are connected and matched, a circular hollow groove is formed. When the fastener 10 is locked, the lower end of the fastener 10 abuts against the circular groove and the flat portion 51 of the lower locking snap ring 50, and the front end of the locking pin 70 is slidably inserted into the locking groove 11 of the fastener 10, thereby preventing the fastener 11 from sliding in the axial direction of the main shaft 20.

[0044] Preferably, the locking bolt 70 is in a semi-T shape and is made of a rigid material. The width of the locking bolt 70 body is adapted to the width of the cavity. The locking bolt 70 body can be pushed, pulled out or rotated in the passage openings at the front and rear ends of the cavity, and the locking bolt 70 body can rotate in the passage, and the front end of the locking bolt 70 body can extend into the locking groove 11 and abut against the locking groove 11. A buckle rod is integrally formed or detachably installed at one end of the locking bolt 70 body, and the buckle rod is perpendicular to the locking bolt 70 body. A convex portion is integrally formed or detachably installed on the side of the locking bolt 70 body away from the buckle rod, and the width of the convex portion is greater than the width of the passage openings at the front and rear ends of the empty slot, so that the locking bolt 70 body cannot be further pushed or pulled out in the passage; the length of the locking bolt 70 body is greater than the length of the passage. Therefore, in the locked state, the front end of the locking pin 70 body can be engaged in the locking groove 11 of the fastener 10, and the snap rod at the rear end of the locking pin 70 body is just snapped into the groove 42 of the upper locking snap ring 40, thereby forming a locked state.

[0045] like Figure 6 As shown, before locking the fastener 10, the main body of the locking latch 70 is pulled outward, and the buckle rod of the locking latch 70 is rotated and buckled on the outside of the convex part, and the fastener 10 is screwed until the lower end surface of the fastener 10 and the flat part 51 of the lower locking snap ring 50 abut against each other, so that the main body of the locking latch 70 is pushed into the channel, and the buckle rod of the locking latch 70 is rotated and buckled in the groove 42 of the upper locking snap ring 40; at this time, the front end of the main body of the locking latch 70 is fixedly engaged in the locking groove 11 at the lower part of the fastener 10, so the locking latch 70 can limit the rotation of the fastener 10 in the axial direction of the spindle 20. The locking function of the push-pull locking structure is reliable and safe to use, and effectively solves the problem that the fasteners of the stirring mechanism are prone to loosening.

[0046] In this embodiment, an elastic component 60 is provided on the outside of the locking bolt 70 body, and the elastic component 60 can be extended and retracted in the empty groove, and has a pushing or pulling effect on the locking bolt 70 body; preferably, the elastic component is a spring. Before locking the fastener 10, the locking bolt 70 body is pulled outward, and the buckle rod can be further tightly buckled on the outer end surface of the lower locking snap ring 50 under the elastic tension of the elastic component, and the fastener 10 is rotated so that the lower end surface of the fastener 10 abuts against the flat portion 51 of the lower locking snap ring 50, and the handle of the locking bolt 70 is pushed into the channel and clamped in the groove 42 of the upper locking snap ring 40, and the handle can be more tightly clamped in the groove 42 under the elastic thrust of the elastic component; at this time, the front end of the locking bolt 70 body is slidably inserted into the locking groove 11 of the fastener 10, thereby preventing the fastener 10 from rotating in the axial direction of the main shaft 20.

[0047] In some embodiments of the utility model, a first protrusion is provided at one end of the upper locking snap ring, and a first groove is provided in the first protrusion; similarly, a second protrusion is provided at a position corresponding to the first protrusion of the upper locking snap ring, and a second groove is provided in the second protrusion. The shape and size of the first protrusion and the first groove are respectively adapted to the shape and size of the second protrusion and the first groove. The upper locking snap ring is connected to the upper part of the lower locking snap ring through a connecting member, and after the connection, the first groove of the upper locking snap ring and the second groove of the lower locking snap ring form a cavity. An elastic component is provided inside the cavity, and the elastic component applies an elastic force toward the main shaft to the locking pin.

[0048] In some other embodiments of the utility model, threaded holes are provided at corresponding positions of the upper locking snap ring and the lower locking snap ring, and the upper locking snap ring and the lower locking snap ring are threadedly connected through a screw nut assembly. Bosses are provided at both ends of the first groove of the upper locking snap ring, and the upper part of the boss is horizontally aligned. The height of the boss is less than the depth of the first groove, and a notch is formed on the boss, so that a notch channel can be formed between the two ends of the first groove and the inner and outer parts; at the same time, a snap-fit ​​groove is provided at the connection between the boss at one end of the first groove and the outer part.

[0049] Similarly, bosses are provided at the corresponding two ends of the second groove of the lower locking snap ring, and the upper part of the bosses is horizontally aligned, and the bosses are adapted to the bosses at the two ends of the first groove in shape and size; the height of the bosses is less than the depth of the second groove, and a notch is formed on the bosses, so that a channel can be formed between the two ends of the second groove and the inner and outer parts. After the upper locking snap ring is connected to the lower locking snap ring, a channel is formed that runs through the front and rear ends of the empty groove, and the locking pin passes through the channel and is inserted into the locking groove of the fastener, thereby preventing the fastener from sliding in the axial direction of the main shaft, effectively solving the problem that the fasteners of the stirring mechanism are prone to loosening under high-intensity working conditions.

[0050] The push-pull locking structure based on the cooking device provided by the utility model is that the locking clamp ring is sleeved on the main shaft and abuts against the main shaft circumferentially to limit the position, and the locking pin is constrained in the locking clamp ring by sliding radially along the locking clamp ring; at the same time, a locking groove is provided on the fastener along the circumferential direction, and when the fastener is in the locking position, the locking pin is slidably inserted into the locking groove. In this structure, the loosening of the fastener is limited by the cooperation between the locking clamp ring, the locking pin, the fastener and the main shaft.

[0051] The push-pull structure provided by the utility model has a reliable locking function, is safe and reliable to use, and has a simple structure, is easy to install and maintain, and effectively solves the problem that the fasteners of the stirring mechanism of the cooking equipment are prone to loosening or even detachment.
