Technical Field
[0001] This utility model belongs to the field of kitchen utensils technology, specifically referring to a rotary drive structure for a food processor. Background Technology
[0002] Currently, utility model application number 201520900417.3 discloses a hand-cranked slicer, including an upper body and a lower body. The handle is screwed to the upper body by a large nut. A hand grip is also connected to the outside of the handle. A cutting tube is provided on the right side of the upper body, and the cutting tube is screwed to the upper body by a large nut. The upper body and the lower body are connected by a snap fastener.
[0003] However, the handle of the aforementioned hand-cranked slicer cannot be folded for storage, taking up a large amount of space and making it difficult to store. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary drive structure that is easy to store and occupies less lateral space when stored.
[0005] The objective of this utility model can be achieved through the following technical solutions: A rotary drive structure for a food processor includes a rotating base and a handle, characterized in that: the rotating base is provided with a receiving groove; one end of the handle is hinged to the receiving groove and can be unfolded outward or folded inward into the receiving groove.
[0006] This rotary drive structure hinges the handle to the receiving slot of the rotating base, allowing it to unfold outwards or fold inwards into the receiving slot. When working, rotating the handle unfolds it; when folding it for storage, rotating the handle inwards folds it into the receiving slot. This effectively reduces the lateral space occupied by the food processor, making it easy to store.
[0007] In the aforementioned rotary drive structure of a food processor, one end of the handle is hinged to the receiving groove via a rotating shaft, and the handle can be fastened to the receiving groove by a locking member; the other end of the handle is provided with a hand crank, which is located outside the rotating seat when the handle is folded into the receiving groove.
[0008] The locking mechanism in this rotary drive structure allows the handle to be fixed in place with the receiving slot after it is unfolded, preventing the handle from wobbling when unfolded. When the handle is unfolded, the hand crank faces outward, and the food processor occupies a large amount of lateral space. When the handle is folded into the receiving slot, the hand crank faces the rotating base, and the lateral space occupied by the food processor is significantly reduced, making it easier to store.
[0009] In the aforementioned rotary drive structure of a food processor, the locking member includes a first latch disposed within the handle. The outer end of the first latch can partially extend out of the first locking hole on the handle and cause the handle to be in an unfolded state. The handle is also provided with a first elastic member that drives the first latch to move outward.
[0010] When the food processor is in operation, rotate the handle to unfold it. At this time, the first latch extends outward under the action of the first elastic element to achieve positioning, ensuring that the handle remains in the unfolded state without wobbling. When the food processor needs to be folded for storage, move the first latch inward and rotate the handle to store it in the rotating base. At this time, the hand crank changes from extending backward to facing the main body of the food processor, which can effectively reduce the lateral space occupied by the food processor and facilitate storage.
[0011] In the aforementioned rotary drive structure of a food processor, a rotary clearance groove is provided on the bottom of the receiving groove. The rotary clearance groove is located at the end of the receiving groove near the rotating shaft. When the handle rotates around the rotating shaft, there is a gap between the end of the handle and the wall of the rotary clearance groove. The first latch can extend outward from the first locking hole and abut against the bottom of the receiving groove inside the rotary clearance groove. The first latch can retract inward into the first locking hole and follow the rotation of the handle into the rotary clearance groove.
[0012] The aforementioned rotary clearance groove design enables the handle to rotate more smoothly, while also ensuring that the handle remains partially within the receiving groove when unfolded, which helps improve the stability of this rotary drive structure during operation.
[0013] In the aforementioned rotary drive structure of a food processor, the handle includes a base plate and a cover plate, which together form a first receiving cavity for accommodating a first latch. The cover plate is provided with a first adjustment hole communicating with the first receiving cavity, and the first latch is formed with a first adjustment part that can extend out of the first adjustment hole.
[0014] When the handle is in the unfolded state, the design of the first latch can play a positioning role. When it is necessary to fold the handle, the first adjustment part is moved manually towards the hand crank to make the first latch retract into the first locking hole, thereby releasing the positioning role of the first latch, allowing the handle to rotate smoothly around the rotation axis and finally fold into the receiving groove.
[0015] In the aforementioned rotary drive structure of a food processor, the outer end of the first latch has an inclined guide surface.
[0016] The design of the aforementioned guide surface allows the handle to rotate from the folded state to the unfolded state without the need for manual adjustment of the position of the first latch. After the guide surface contacts the outer edge of the rotation clearance groove or receiving groove, it will be automatically pressed into the first locking hole, thereby enabling the handle to rotate smoothly to the unfolded state.
[0017] In the aforementioned rotary drive structure of a food processor, a connecting post is provided on the rotating base. The connecting post can pass through the rear end of the processor body and be inserted and fixed to the rear end of the rotating body within the processor body. A connecting groove is provided at the rear end of the rotating body, and a positioning groove is provided on the wall of the connecting groove. A second latch is provided inside the connecting post, and a second locking hole is provided on the outer wall of the connecting post for the second latch to extend out. A second elastic element is provided inside the connecting post to drive the second latch to extend out of the second locking hole and insert into the positioning groove.
[0018] The design of the connecting column and the second latch enables quick connection and disassembly of the rotating seat and the rotating body. The design of the second elastic element ensures that the second latch can keep the connecting column and the rotating body locked in place without external force.
[0019] In the aforementioned rotary drive structure of a food processor, the rotary seat is provided with a second accommodating cavity for accommodating a second latch, the accommodating groove is provided with a second adjusting hole communicating with the second accommodating cavity, and the second latch is formed with a second adjusting part that can extend out of the second adjusting hole.
[0020] When disassembling the rotating base and the rotating body, move the second adjusting part to retract the second latch into the second locking hole, and then pull the connecting post out of the connecting groove. The structure is simple and the operation is convenient.
[0021] In the aforementioned rotary drive structure of a food processor, the connecting column is a regular polygon, the connecting groove is a regular polygon structure that mates with the connecting column, and each wall of the connecting groove is provided with a positioning groove.
[0022] The aforementioned regular polygonal structure of the connecting post and connecting groove facilitates the insertion and mating of the two, and also facilitates the alignment and locking of the positioning groove and the second latch.
[0023] In the aforementioned rotary drive structure of a food processor, an adjustment relief groove is provided on the cover plate, and the first adjustment hole is provided on one side of the adjustment relief groove. When the handle is folded and stored in the receiving groove, the second adjustment part can be extended into the other side of the adjustment relief groove.
[0024] The aforementioned adjustment groove design allows the rear side of the handle and the rear side of the rotating seat to be flatter after folding, which helps to improve the stability and aesthetics of the entire rotating drive structure after folding.
[0025] Compared with the prior art, the technical effects of this utility model are as follows: This invention features a rotating base and handle that can be unfolded and folded. When in operation, rotating the handle unfolds it, and the first latch extends outward under the action of the first elastic element to achieve positioning, ensuring the handle remains stable in the unfolded state. When folding for storage, moving the first latch inward and rotating the handle retracts it into the rotating base. At this time, the hand crank changes from extending backward to facing the main body of the food processor, effectively reducing the lateral space occupied by the food processor and facilitating storage.

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0035] The rotary drive structure of this food processor includes a rotating base 1 and a handle 2. The rotating base 1 is provided with a receiving groove 11. One end of the handle 2 is hinged to the receiving groove 11, allowing it to unfold outward or fold inward within the receiving groove 11. This rotary drive structure, by hinged the handle 2 to the receiving groove 11 of the rotating base 1, enables it to unfold outward or fold inward within the receiving groove 11. When working, rotating the handle 2 unfolds it; when folding it for storage, rotating the handle 2 inward folds it into the receiving groove 11. This effectively reduces the lateral space occupied by the food processor, facilitating storage.
[0036] Furthermore, one end of the handle 2 is hinged to the receiving groove 11 via a rotating shaft 29, and the handle 2 can be fastened to the receiving groove 11 by a locking member; the other end of the handle 2 is provided with a hand crank 3. When the handle 2 is folded into the receiving groove 11, the hand crank 3 is located outside the rotating base 1. The locking member in this rotary drive structure can fix the handle 2 to the receiving groove 11 after it is unfolded, preventing the handle 2 from shaking in the unfolded state. At the same time, when the handle 2 is in the unfolded state, the hand crank 3 faces outward, and the entire food processor occupies a large lateral space. When the handle 2 is folded into the receiving groove 11, the hand crank 3 faces the rotating base 1, and the lateral space occupied by the entire food processor is significantly reduced, making it easier to store.
[0037] The aforementioned locking component includes a first latch 21 disposed within the handle 2. The outer end of the first latch 21 can partially extend out of the first locking hole 22 on the handle 2, allowing the handle 2 to be in an unfolded state. The handle 2 also contains a first elastic element 27 that drives the first latch 21 to move outward. When operation is required, rotating the handle 2 unfolds it, at which point the first latch 21 extends outward under the action of the first elastic element 27 to achieve positioning, ensuring the handle 2 remains stable in the unfolded state. When folding for storage, moving the first latch 21 inward and rotating the handle 2 allows it to be stored within the rotating base 1. At this time, the hand crank 3 changes from a rearward extended state to a direction towards the food processor body 5, effectively reducing the lateral space occupied by the food processor and facilitating storage. Furthermore, the aforementioned locking component can also be a positioning plate. One end of the positioning plate is rotatably connected to the outer side of the rotating base 1. The positioning plate can rotate to a position perpendicular to the length of the receiving groove 11 and limit the handle 2. The other end of the positioning plate is detachably fixed to the rotating base 1.
[0038] like Figure 2 and Figure 3As shown, a rotating clearance groove 12 is provided on the bottom of the receiving groove 11. The rotating clearance groove 12 is located at the end of the receiving groove 11 near the rotating shaft 29. When the handle 2 rotates around the rotating shaft 29, there is a gap between the end of the handle 2 and the groove wall of the rotating clearance groove 12. The first latch 21 can extend outward from the first locking hole 22 and abut against the bottom of the receiving groove 11 inside the rotating clearance groove 12. The first latch 21 can retract inward into the first locking hole 22 and follow the rotation of the handle 2 into the rotating clearance groove 12. The design of the rotating clearance groove 12 makes the rotation of the handle 2 smoother, and also ensures that the handle 2 is still partially located in the receiving groove 11 when unfolded, which is beneficial to improving the stability of this rotary drive structure during operation.
[0039] Furthermore, the handle 2 includes a base plate 23 and a cover plate 24. The base plate 23 and the cover plate 24 together form a first receiving cavity 25 for accommodating the first latch 21. The cover plate 24 is provided with a first adjustment hole 26 communicating with the first receiving cavity 25. The first latch 21 is formed with a first adjustment part 211 that can extend out of the first adjustment hole 26. When the handle 2 is in the unfolded state, the design of the first latch 21 can play a positioning role. When it is necessary to fold the handle 2, by manually moving the first adjustment part 211 towards the hand crank 3, the first latch 21 is retracted into the first locking hole 22, thereby releasing the positioning role of the first latch 21, so that the handle 2 can smoothly rotate around the rotation axis 29 and finally fold into the receiving groove 11.
[0040] like Figure 4 As shown, the outer end of the first latch 21 has an inclined guide surface 212. The design of the guide surface 212 allows the handle 2 to rotate from the folded state to the unfolded state without the need for manual adjustment of the position of the first latch 21. After the guide surface 212 contacts the outer edge of the rotation clearance groove 12 or the receiving groove 11, it will be automatically pressed into the first locking hole 22, thereby allowing the handle 2 to rotate smoothly to the unfolded state.
[0041] like Figure 1-3 and Figure 5 As shown, a connecting post 13 is provided on the rotating base 1. The connecting post 13 can pass through the rear end of the processor body 5 and be inserted and fixed to the rear end of the rotating body 4 inside the processor body 5. The rear end of the rotating body 4 is provided with a connecting groove 41, and the groove wall of the connecting groove 41 is provided with a positioning groove 42. A second latch 14 is provided inside the connecting post 13. A second locking hole 131 is provided on the outer wall of the connecting post 13 for the second latch 14 to extend out. A second elastic element 17 is provided inside the connecting post 13 to drive the second latch 14 to extend out of the second locking hole 131 and insert into the positioning groove 42. The design of the connecting post 13 and the second latch 14 enables quick connection and disassembly between the rotating base 1 and the rotating body 4. The design of the second elastic element 17 ensures that the second latch 14 can keep the connecting post 13 and the rotating body 4 locked without external force intervention.
[0042] Furthermore, the rotating base 1 is provided with a second receiving cavity 15 for accommodating the second latch 14, and the receiving groove 11 is provided with a second adjusting hole 16 communicating with the second receiving cavity 15. The second latch 14 is formed with a second adjusting part 141 that can extend out of the second adjusting hole 16. When separating the rotating base 1 and the rotating body 4, the second adjusting part 141 is moved to retract the second latch 14 into the second locking hole 131, and then the connecting post 13 is pulled out from the connecting groove 41. The structure is simple and the operation is convenient.
[0043] like Figure 5 As shown, the connecting post 13 is a regular polygon, and the connecting groove 41 is a regular polygon structure that mates with the connecting post 13. Each wall of the connecting groove 41 is provided with a positioning groove 42. The aforementioned regular polygon structure of the connecting post 13 and the connecting groove 41 facilitates the insertion and mating of the two, and also facilitates the alignment and locking of the positioning groove 42 and the second latch 14.
[0044] like Figure 1-3 As shown, the cover plate 24 is provided with an adjustment relief groove 28, and the first adjustment hole 26 is provided on one side of the adjustment relief groove 28. When the handle 2 is folded and stored in the receiving groove 11, the second adjustment part 141 can extend into the other side of the adjustment relief groove 28. The design of the adjustment relief groove 28 makes the rear side of the folded handle 2 and the rear side of the rotating seat 1 more flat, which is beneficial to improving the stability and aesthetics of the entire rotary drive structure after folding.
[0045] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
