[0002] An ice cream maker is a common food processing device, typically comprising a housing, a container, a mixing blade, a crushing blade, and a drive motor. The container is used to hold the food to be processed, and the crushing blade is rotatably disposed at the inner bottom end of the container and is driven by the drive motor to rotate and crush the food. The output shaft of the drive motor (hereinafter referred to as the "output shaft") is connected to the rotating shaft of the crushing blade via a coupling bracket. The coupling bracket and the output shaft are fixedly connected via a connector (e.g., a screw or bolt) threaded onto the output shaft. However, when using the connector to securely connect the coupling bracket to the output shaft, a problem arises: Since the output shaft can rotate freely during the rotational connection, it is difficult to achieve a threaded connection between the coupling bracket and the output shaft. This problem urgently needs to be addressed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] In the description of this application, it should be understood that the terms "length," "width," "thickness," "up," "down," "left," "right," "front," "back," "top," "bottom," "inside," "outside," "center," "vertical," "horizontal," "transverse," and "longitudinal" and the like, indicating positions or state relationships, are based on the positions or state relationships shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments, and are not intended to limit the devices, elements, or components indicated to having a specific position, or being constructed or operated in a specific position.

[0025] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or state. For example, the term "on" may also be used to express a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0026] In addition, the terms "first," "second," etc. are primarily used to distinguish different devices, elements, or components (the specific types and configurations of which may be the same or different), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0027] Furthermore, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; internal communication between two components; or mere surface contact. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0028] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in their functionality. For example, the term "including" used throughout the specification and claims is an open-ended term and should be interpreted as meaning "including but not limited to." "Substantially" means that those skilled in the art can solve the technical problem within a certain error range and achieve a substantial technical effect.

[0029] An ice cream maker is a common food processing device, typically comprising a housing, a container, a mixing blade, a crushing blade, and a drive motor. The container is used to hold the food to be processed, and the crushing blade is rotatably disposed at the inner bottom end of the container and is driven by the drive motor to rotate and crush the food. The output shaft of the drive motor (hereinafter referred to as the "output shaft") is connected to the rotating shaft of the crushing blade via a coupling bracket. The coupling bracket and the output shaft are fixedly connected via a connector (e.g., a screw, bolt, etc.) threaded onto the output shaft. However, when using the connector to securely connect the coupling bracket to the output shaft, a problem arises: the coupling bracket can only be installed after both the container and the drive motor are securely installed, and the container is located above the drive motor. Therefore, the coupling bracket can only be connected to the output shaft from above the drive motor after passing through the bottom opening of the container. During the process of rotational connection between the connector and the output shaft, the output shaft can rotate freely, and the installation space is small, making it difficult to secure the output shaft using tools. Therefore, it is difficult to achieve a threaded connection between the connector and the output shaft. In order to solve the above problems, an embodiment of the present application provides a fixture 100 to facilitate workers to achieve a fixed connection between the coupling bracket and the output shaft of the drive motor through a connecting piece.

[0030] See also Figure 1 and Figure 2 The embodiment of the present application provides a fixture 100 (see Figure 6 and Figure 7 ), which is used to be installed on a fixed installation member 200, so as to be applied to the installation process of the first rotating member 300 and the second rotating member 400 with a non-rotatable connection. It should be understood that the "non-rotatable connection" between the first rotating member 300 and the second rotating member 400 should be understood as that there is a connection relationship between the first rotating member 300 and the second rotating member 400, but the relative rotation between the first rotating member 300 and the second rotating member 400 is prohibited. The first rotating member 300 and the second rotating member 400 are relatively fixed. When one of the first rotating member 300 and the second rotating member 400 actively rotates, the other will follow the rotation. When one of the first rotating member 300 and the second rotating member 400 stops rotating, the other will also stop rotating. The non-rotatable connection between the first rotating member 300 and the second rotating member 400 can be achieved through various structures, such as a plug-in connection through a non-circular hole, a key connection, etc.

[0031] Among them, the mounting member 200 is provided with a receiving hole 20 for receiving the fixture 100. It should be noted that the receiving hole 20 can be a through hole opened on the mounting member 200, or a hole structure formed by a structure on the mounting member 200. For example, the receiving hole 20 can be a through hole formed by a cylindrical structure on the mounting member 200. The first rotating member 300 is rotatably arranged. The first rotating member 300 can be a structure that can rotate by itself, or it can be connected to a rotating driving member to drive itself to rotate. The second rotating member 400 is sleeved on one end of the first rotating member 300 to rotate synchronously with the first rotating member 300 or to be stationary synchronously, and is used to be connected to the first rotating member 300 through a connecting member 500. The above-mentioned connecting member 500 can be a fastener such as a screw or a bolt.

[0032] See also Figure 5 As a specific example, in this embodiment, the mounting member 200 is a container for the ice cream machine, the first rotating member 300 is an output shaft of the driving motor of the ice cream machine, the second rotating member 400 is a coupling bracket of the ice cream machine, and the connecting member 500 is a screw. The specific structure and usage process of the above-mentioned fixture 100 are described in detail.

[0033] See also Figure 6 and Figure 7 The fixture 100 includes a mounting seat 10 , a limiting member 11 and a clamping member 12 .

[0034] The mounting base 10 is the main structure of the fixture 100. As a specific example, in this embodiment, the mounting base 10 is generally cylindrical and matches the shape of the receiving hole 20. In other embodiments, the mounting base 10 can also be any other shape, such as a rectangular parallelepiped or a cube. At least part of the structure of the mounting base 10 is accommodated in the receiving hole 20 (see FIG. Figure 2 and Figure 4 ) inside, the mounting seat 10 is provided with a clearance hole 101 for allowing the connecting member 500 to pass through.

[0035] The limiter 11 is a structure of the fixture 100 used to limit the relative rotation between itself and the mounting member 200. The limiter 11 is connected to the mounting base 10 and protrudes relative to the mounting base 10, so as to engage with the mounting member 200 and prevent the mounting base 10 from rotating. The limiter 11 can be a rod-shaped structure, a block-shaped structure, or any other structure protruding from the surface of the mounting base 10. The inner side wall of the receiving hole 20 can be provided with a limit groove 21 adapted to the limiter 11 (see Figure 2 and Figure 4 ), when the mounting seat 10 is accommodated in the accommodating hole 20, the limiting member 11 can be embedded in the limiting groove 21 to achieve the clamping connection between the mounting seat 10 and the mounting member 200. At the same time, the inner side wall of the limiting groove 21 can also support the limiting member 11 to keep the mounting seat 10 stable in the accommodating hole 20.

[0036] The clamping member 12 is a structure of the fixture 100 used to limit the relative rotation of the second rotating member 400 relative to itself. The clamping member 12 is connected to the end of the mounting base 10 facing the second rotating member 400. The clamping member 12 is plugged into the second rotating member 400 and is located on the rotation path of the second rotating member 400 and the first rotating member 300. The clamping member 12 can be a rod-shaped structure, a block structure, or any other structure. Figure 2 and Figure 3 The second rotating member 400 may be provided with an insertion slot 40 for inserting the holding member 12, and the inner sidewall of the insertion slot 40 may be provided with a mating member 41 for engaging with the holding member 12. When the second rotating member 400 rotates to a position where the mating member 41 abuts against the holding member 12, the mating member 41 cannot continue to rotate because the position of the holding member 12 is fixed, thereby causing the second rotating member 400 and the first rotating member 300 to stop rotating.

[0037] When the staff uses the above-mentioned jig 100, they first install the mounting seat 10 of the jig 100 in the receiving hole 20 of the mounting member 200. Since the jig 100 is provided with a limiting member 11, the limiting member 11 is engaged with the fixed mounting member 200 to keep the position of the mounting seat 10 fixed; since the jig 100 is provided with a clamping member 12 connected to the mounting seat 10, the clamping member 12 is plugged into the second rotating member 400 and is located on the rotation path of the second rotating member 400 and the first rotating member 300 rotating synchronously, when the second rotating member 400 rotates synchronously with the first rotating member 300, When the moving member 400 meets the holding member 12, the holding member 12 can prevent the second rotating member 400 from continuing to rotate synchronously with the first rotating member 300, thereby keeping both the second rotating member 400 and the first rotating member 300 stationary. At this time, the staff can smoothly rotate and insert the connecting member 500 into the first rotating member 300, and ultimately achieve a fixed connection between the first rotating member 300 and the second rotating member 400. After the connection operation is completed, the staff can simply remove the jig 100 from the receiving hole 20 along the axial direction of the receiving hole 20, which is convenient to operate. In summary, the above-mentioned jig 100 has the beneficial effect of facilitating the staff to securely connect the first rotating member 300 and the second rotating member 400 via the connecting member 500.

[0038] See also Figure 2 、 Figure 6 and Figure 7The limiting member 11 protrudes relative to the mounting seat 10 along the radial direction of the clearance through-hole 101, and a plurality of limiting members 11 are provided, and the plurality of limiting members 11 are spaced apart from each other on the outer peripheral wall of the mounting seat 10. As a specific example, in this embodiment, the limiting member 11 is a block-shaped structure protruding relative to the mounting seat 10 along the radial direction of the clearance through-hole 101, and there are two limiting members 11, and the two limiting members 11 are roughly arranged relative to the mounting seat 10. In other embodiments, the limiting member 11 can also be a rod-shaped structure, a strip-shaped structure, or any other structure protruding relative to the mounting seat 10 along the radial direction of the clearance through-hole 101, and the limiting member 11 can also be provided in any number such as three or four. This embodiment does not limit the specific form of the limiting member 11 and the number of the limiting members 11.

[0039] Through the above arrangement, the plurality of limiting members 11 can improve the limiting effect on the mounting seat 10 , so that the mounting seat 10 can be more stably accommodated in the accommodating hole 20 to prevent the fixture 100 from rotating relative to the mounting member 200 .

[0040] See also Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , the holding member 12 is extended along the axial direction O of the clearance through hole 101, and a plurality of holding members 12 are provided, and the plurality of holding members 12 are evenly distributed along the circumferential intervals of the clearance through hole 101. As a specific example, in this embodiment, the holding member 12 is a rod-shaped structure extended along the axial direction O of the clearance through hole 101, and the number of the holding members 12 is four, and the four holding members 12 are evenly distributed along the circumferential intervals of the clearance through hole 101. In other embodiments, the holding member 12 can also be a block structure, a strip structure, or any other structure extending along the axial direction O of the clearance through hole 101, and the number of the holding members 12 can also be two, three, five, or any other number. This embodiment does not limit the specific form of the holding member 12 and the number of the holding members 12.

[0041] Through the above-mentioned setting, multiple clamping members 12 can improve the rotation limiting effect of the fixture 100 on the second rotating member 400, so that the clamping member 12 can stably prevent the rotation of the second rotating member 400 and the first rotating member 300, so as to achieve the fixation of the first rotating member 300, thereby facilitating the staff to rotate the connecting member 500 to the first fixed member.

[0042] See also Figure 2 and Figure 7In some embodiments, the clamping member 12 has a first end 121 and a second end 122 that are separated from each other. The first end 121 is connected to the mounting base 10, and the second end 122 has a smaller dimension in the direction O perpendicular to the axis of the clearance hole 101 than the first end 121. With the above arrangement, the second end 122 of the clamping member 12 that is away from the mounting base 10 is more easily inserted into the insertion groove 40 of the second rotating member 400 (refer to Figure 3 ) so that the holding member 12 contacts and cooperates with the matching member 41 to prevent the second rotating member 400 and the first rotating member 300 from continuing to rotate.

[0043] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, the fixture 100 further includes a lifting member 13, which is disposed on the mounting seat 10. The lifting member 13 protrudes relative to the mounting seat 10 along the radial direction of the clearance hole 101, and the distance between the lifting member 13 and the axis of the clearance hole 101 is greater than the radius of the receiving hole 20. As a specific example, in this embodiment, the lifting member 13 is a block-shaped structure that protrudes relative to the mounting seat 10 along the radial direction of the clearance hole 101. In other embodiments, the limiting member 11 may also be a rod-shaped structure, a strip-shaped structure, or any other structure that protrudes relative to the mounting seat 10 along the radial direction of the clearance hole 101. This embodiment does not limit the specific form of the limiting member 11.

[0044] Through the above arrangement, since the distance from the lifting member 13 to the axis of the yielding through hole 101 is greater than the radius of the accommodating hole 20, the lifting member 13 will be clamped on other structures of the mounting member 200 to prevent the mounting seat 10 from being completely accommodated in the accommodating hole 20. This not only makes it convenient for the staff to remove the jig 100 from the accommodating hole 20, but the clamping of the lifting member 13 and other structures of the mounting member 200 can also improve the stability of the mounting seat 10 in the accommodating hole 20, thereby improving the anti-rotation effect of the jig 100 on the first rotating member 300 and the second rotating member 400.

[0045] In some embodiments, multiple lifting members 13 are provided, spaced apart from each other on the outer peripheral wall of the mounting base 10. As a specific example, in this embodiment, two lifting members 13 are provided, and the two lifting members 13 are generally arranged opposite each other with respect to the mounting base 10. In other embodiments, any number of lifting members 13 may be provided, such as three or four, and this embodiment does not limit the number of lifting members 13.

[0046] Through the above-mentioned arrangement, the multiple lifting members 13 can not only facilitate the staff to remove the jig 100 from the accommodating hole 20, but also improve the stability of the mounting seat 10 accommodated in the accommodating hole 20, thereby improving the anti-rotation effect of the jig 100 on the first rotating member 300 and the second rotating member 400.

[0047] See also Figure 6 and Figure 7 In some embodiments, the projections of the lifting member 13 and the limiting member 11 in the vertical direction do not overlap. The vertical direction is substantially the same as the axial direction O of the clearance hole 101. With the above arrangement, when the staff puts the jig 100 into the receiving hole 20 along the vertical direction, the lifting member 13 will not block the staff's sight too much, so that the staff can observe the limiting member 11 and the limiting groove 21 (refer to Figure 5 ) are aligned, thereby more efficiently assembling the fixture 100 and the mounting member 200.

[0048] See also Figure 2 In some embodiments, the clearance hole 101 includes a first hole segment 1011, a second hole segment 1012, and a third hole segment 1013 that are connected in series. The first hole segment 1011 is located at the end of the clearance hole 101 away from the retaining member 12. The aperture of the first hole segment 1011 is larger than the aperture of the second hole segment 1012, and the aperture of the second hole segment 1012 is larger than the aperture of the third hole segment 1013. It should be noted that the aperture of the first hole segment 1011 being larger than the aperture of the second hole segment 1012 means that the maximum aperture of the first hole segment 1011 is larger than the maximum aperture of the second hole segment 1012, and the aperture of the second hole segment 1012 being larger than the aperture of the third hole segment 1013 means that the maximum aperture of the second hole segment 1012 is larger than the maximum aperture of the third hole segment 1013. Through the above-mentioned arrangement, when the staff is initially inserting the connecting member 500 into the clearance hole 101, since the aperture of the third hole section 1013 is relatively large, the operating space is also large, which is convenient for operation. As the connecting member 500 continues to move downward in the clearance hole 101, the aperture of the clearance hole 101 gradually decreases, which plays a role of gradual guidance, making it easier for the connecting member 500 to be aligned with the connection structure of the first rotating member 300 (such as the threaded connection hole), thereby facilitating the threaded connection between the connecting member 500 and the first connecting member 500.

[0049] In some embodiments, the diameter of the second hole segment 1012 gradually decreases from the end closest to the first hole segment 1011 to the end closest to the third hole segment 1013. With this arrangement, the second hole segment 1012 is used to guide the connector 500 located in the third hole segment 1013 into the first hole segment 1011, thereby making the connector 500 move downwards in the clearance hole 101 smoother and facilitating connection.

[0050] In some embodiments, the mounting base 10, the stopper 11, and the retaining member 12 are integrally formed and connected. For example, the mounting base 10, the stopper 11, and the retaining member 12 can be integrally formed and manufactured using an injection molding process or an extrusion process, thereby facilitating manufacturing. In other embodiments, the mounting base 10, the stopper 11, and the retaining member 12 can also be independently manufactured and then connected using bonding, fasteners, or other connection methods.

[0051] In summary, the embodiment of the present application provides a jig 100. When a worker uses the jig 100 to connect the coupling bracket of an ice cream machine and the output shaft of a drive motor, the following operations need to be performed:

[0052] The staff first installs the mounting seat 10 of the jig 100 in the receiving hole 20 of the holding container of the ice cream machine. Since the jig 100 is provided with a limit member 11, the limit member 11 is engaged with the fixed holding container to keep the position of the mounting seat 10 fixed; since the jig 100 is provided with a clamping member 12 connected to the mounting seat 10, the clamping member 12 is plugged into the coupling bracket and is located on the rotation path of the coupling bracket and the output shaft of the drive motor rotating synchronously, so when the coupling bracket meets the clamping member 12, the clamping member 12 can prevent the coupling bracket and the output shaft of the drive motor from continuing to rotate synchronously, so that the output shaft of the coupling bracket and the drive motor remain stationary; at this time, the staff can smoothly rotate and insert the connecting member 500 into the output shaft of the drive motor, and finally realize the fixed connection between the output shaft of the drive motor and the coupling bracket; after the connection operation is completed, the staff can take the jig 100 out of the receiving hole 20 along the axial direction of the receiving hole 20, which is easy to operate. In summary, the fixture 100 has the beneficial effect of facilitating the worker to fix the output shaft of the driving motor and the coupling bracket through the connecting piece 500 .
