A locking unit and a cooking robot

Abstract

This utility model relates to a locking unit and a cooking robot. A limiting block is detachably mounted on the locked component, and a constraint structure prevents relative rotation between the limiting block and the locked component. After the locking nut and the locked component are threadedly connected, the protruding structure on the locking nut can engage with the limiting structure on the limiting block. Because the limiting block and the locked component cannot rotate, the locking nut cannot rotate relative to the locked component after the protruding structure engages with the limiting structure, thus preventing loosening and locking. Furthermore, since the limiting block and the locked component are detachably connected, and the locking nut and the locked component are threadedly connected, it facilitates disassembly and installation by the operator. Compared with the prior art, the locking unit and cooking robot disclosed in this application can achieve stable locking over time, with equipment use and frequent installation and disassembly.

[0003] Due to the need for installation and disassembly in automatic cooking machines, some components need to be installed in a modular manner. Conventional installation and disassembly methods often use nuts to fix the locked parts. Over time, with the use of the equipment and frequent installation and disassembly, the nuts will loosen. This situation will be more serious and prominent when the locked part is a rotating shaft. Utility Model Content

[0004] To address the issue that nuts may loosen over time due to equipment use and frequent installation and removal, this invention proposes a locking unit.

[0005] The technical solution adopted by this utility model is a locking unit, comprising:

[0006] The limiting block is detachably mounted on the locked part and the rotational freedom between the limiting block and the locked part is restricted by the constraint structure;

[0007] The locking nut is threadedly connected to the locked part. The locking nut has a protruding structure, which is engaged with the limiting structure of the limiting block.

[0008] In some embodiments, a limit stop is fitted onto the locked member.

[0009] In some embodiments, the constraint structure consists of a non-circular cross-section shaft disposed on the locked member and a non-circular cross-section hole disposed on the limiting block. The limiting block is sleeved on the non-circular cross-section shaft through the non-circular cross-section hole, and the non-circular cross-section hole and the non-circular cross-section shaft cooperate with each other.

[0010] In some embodiments, the limiting structure includes at least two limiting holes arranged circumferentially along the locked member.

[0011] In some embodiments, the protruding structure protrudes outward in the locking direction of the locking nut.

[0012] In some embodiments, the locking element is a pivot.

[0013] In some embodiments, the locking nut has a placement hole, and a protruding structure is connected to the placement hole.

[0014] In some embodiments, the protruding structure has an extended state and a reset state. In the extended state, the extended end of the protruding structure is engaged within the limiting structure.

[0015] In the reset state, the protruding end of the protruding structure is located inside the lock nut.

[0016] In some embodiments, the protruding structure includes a retaining pin and a spring, one end of the spring abutting against a placement hole and the other end abutting against the retaining pin.

[0017] In some embodiments, the retaining pin has a circumferentially open receiving groove, and a spring is sleeved outside the retaining pin, with one end of the spring abutting the bottom of the receiving groove and the other end abutting the placement hole.

[0018] In some embodiments, the placement hole has a first region and a second region, the diameter of the first region is larger than the diameter of the second region, the receiving groove is located in the first region, one end of the spring abuts against the bottom of the receiving groove, and the other end abuts against the step surface between the first region and the second region.

[0019] In some embodiments, the placement hole is a through hole, and the fixing pin is threadedly connected to the lock nut at the location of the first region.

[0020] In some embodiments, the placement hole is a through hole, and the protruding structure includes a retaining pin, which is threadedly connected to the placement hole.

[0021] To address the need for modular installation of some components in automatic cooking machines due to installation and disassembly requirements, and the defect that locking units are prone to loosening and affecting the normal use of components, this utility model proposes a cooking robot.

[0022] The technical solution adopted by this utility model is a cooking robot, which includes the locking unit mentioned above.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This application discloses a locking unit in which a limiting block is detachably mounted on the locked component. A constraint structure prevents relative rotation between the limiting block and the locked component. After the locking nut and the locked component are threadedly connected, a protruding structure on the locking nut engages with the limiting structure on the limiting block. Because rotation between the limiting block and the locked component is impossible, the locking nut also cannot rotate relative to the locked component after the protruding structure engages with the limiting structure, thus preventing loosening and locking. Furthermore, the detachable connection between the limiting block and the locked component, along with the threaded connection between the locking nut and the locked component, facilitates disassembly and installation by operators.

[0025] Compared with the prior art, the locking unit disclosed in this application can achieve a stable locking purpose over time, with the use of the equipment and frequent installation and removal.

[0026] This application discloses a cooking robot, including the aforementioned locking unit. The cooking robot disclosed in this application can stably install and fix the locked components, ensuring that the locking unit will not loosen and thus prevent the normal use of the components from being affected.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Examples of embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] This utility model discloses a locking unit, please refer to... Figures 1 to 4 ,include:

[0039] The limiting block 10 is detachably mounted on the locked member 30 and the rotational freedom between the limiting block 10 and the locked member 30 is limited by the constraint structure 11;

[0040] The locking nut 20 is threadedly connected to the locked part 30. The locking nut 20 has a protruding structure 21, which is engaged with the limiting structure 12 of the limiting block 10.

[0041] The limiting block 10 is detachably mounted on the locked member 30, and the constraint structure 11 prevents relative rotation between the limiting block 10 and the locked member 30. After the locking nut 20 and the locked member 30 are threadedly connected, the protruding structure 21 on the locking nut 20 can engage with the limiting structure 12 on the limiting block 10. Since the limiting block 10 and the locked member 30 cannot rotate, the locking nut 20 also cannot rotate relative to the locked member 30 after the protruding structure 21 engages with the limiting structure 12, thus achieving the function of preventing loosening and locking. Furthermore, since the limiting block 10 and the locked member 30 are detachably connected, and the locking nut 20 and the locked member 30 are threadedly connected, it is convenient for operators to disassemble and install. Compared with the prior art, the locking unit disclosed in this application can achieve stable locking over time, with equipment use, and frequent installation and disassembly.

[0042] Specifically, the limit block 10 can be detachably installed on the locked part 30 in a way that includes sleeve installation, through slot snap-fit, or other detachable methods.

[0043] The constraint structure 11 can restrict rotational freedom through the structure of the limiting block 10 and the locked member 30 itself, or through an external structure. Restricting rotational freedom through the limiting block 10 itself can be achieved through a through-slot connection, where a through-slot is formed on the locked member 30, and the limiting block 10 is inserted into the through-slot, thus achieving both detachability and restriction of rotational freedom. Restricting rotational freedom through an external structure can be achieved through methods such as pin fixing.

[0044] The protruding structure 21 refers to the structure that is provided on the locking nut 20 and protrudes outward. The purpose of the protruding structure 21 is to be able to engage with the limiting structure 12 on the phase stop.

[0045] The limiting structure 12 can be a hole, groove, hook, or other structure.

[0046] This application does not limit the contact between the protruding structure 21 and the limiting structure 12, nor does it require contact between the limiting block 10 and the locking nut 20 at other locations. Preferably, the limiting block 10 and the locking nut 20 are positioned close to each other, and the protruding structure 21 and the limiting structure 12 are interlocked. This results in a compact locking unit to adapt to more application scenarios.

[0047] Furthermore, this application does not limit the position of the locking nut 20; the locking nut 20 can be located at the end of the locked member 30 or at the middle of the locked member 30. Preferably, the locking nut 20 is fixed at the end of the locked member 30, thereby facilitating disassembly and installation.

[0048] In some embodiments, please refer to Figures 1 to 3 Locking nut 20 is a blind hole nut.

[0049] In some specific embodiments, please refer to Figures 1 to 3 The blind hole nut is a hexagonal blind hole nut.

[0050] In some embodiments, please refer to Figures 1 to 4 The limit stop 10 is set on the locked part 30.

[0051] It should be noted that the limit block 10 is sleeved on the locked part 30, and the limit block 10 can be installed and removed in the axial direction of the locked part 30, thereby realizing the detachable setting of the limit block 10.

[0052] In some embodiments, please refer to Figures 1 to 4 The constraint structure 11 consists of a non-circular cross-section shaft provided on the locked member 30 and a non-circular cross-section hole provided on the limiting block 10. The limiting block 10 is sleeved on the non-circular cross-section shaft through the non-circular cross-section hole, and the non-circular cross-section hole and the non-circular cross-section shaft cooperate with each other.

[0053] Since the limiting block 10 is already fitted onto the locked member 30, the restriction of rotational freedom can be achieved by changing the cross-sectional shape of the limiting block 10 and the locked member 30 to create a non-circular cross-section fit between them. Specifically, the limiting block 10 is fitted onto the locked member 30 through a non-circular cross-section hole. The cross-section of the area on the locked member 30 where the limiting block 10 is placed is also a non-circular cross-section. The non-circular cross-section hole and the non-circular cross-section shaft can fit together to prevent rotation. The non-circular cross-section can be polygonal or a circle with a portion removed, etc.

[0054] In some embodiments, please refer to Figure 4 The limiting structure 12 includes at least two limiting holes, which are arranged circumferentially along the locked part.

[0055] Specifically, the limiting structure 12 includes multiple limiting holes. Since the locking nut 20 is threaded to the locked part 30, if only one limiting hole is provided, the protruding structure 21 may not be able to properly engage with the limiting hole. However, by providing multiple limiting holes and arranging them along the circumference of the locked part, the protruding structure 21 can select a suitable limiting hole for engagement.

[0056] In some embodiments, please refer to Figures 1 to 4 The protruding structure 21 protrudes outward in the locking direction of the locking nut 20.

[0057] It should be noted that, in order to make the locking unit more compact and the cooperation between the various structures more coordinated, the protruding structure 21 protrudes outward in the locking direction of the locking nut 20.

[0058] In other embodiments, the protruding structure 21 may also protrude outward in the radial direction of the locked member 30. In this case, the shape of the limiting block 10 can be adaptively adjusted according to the protruding position of the protruding structure 21 to adapt to the snap-fit ​​relationship between the protruding structure 21 and the limiting structure 12.

[0059] In some embodiments, please refer to Figures 1 to 3 The locked component 30 is a rotating shaft.

[0060] It should be noted that the locking part 30 in this application can be either a rotating part or a non-rotating part. When the locking part 30 is a rotating part, the nut is more likely to loosen, so it is more necessary to provide an anti-loosening locking structure for the rotating part.

[0061] In some embodiments, please refer to Figures 1 to 3The locking nut 20 has a placement hole 24, and the protruding structure 21 is connected inside the placement hole 24.

[0062] To avoid increasing the volume of the locking nut 20, this application places the protruding structure 21 inside the locking nut 20, and provides a placement hole 24 inside the locking nut 20, with the protruding structure 21 connected to the placement hole 24. It should be noted that the protruding structure 21 can also be a pin, and the placement hole 24 can be a through hole. When the locking nut 20 is installed in place, the pin can pass through the through hole and insert into the limiting structure 12, thereby achieving limiting.

[0063] Furthermore, since the protruding structure 21 is located inside the locking nut 20, the locking nut 20 can be installed and removed using a general-purpose tool.

[0064] In some embodiments, please refer to Figures 1 to 3 The protruding structure 21 has an extended state and a reset state. In the extended state, the extended end of the protruding structure 21 is engaged in the limiting structure 12.

[0065] In the reset state, the protruding end of the protruding structure 21 is located inside the locking nut 20.

[0066] It should be noted that, to facilitate the disassembly and installation of the locking nut 20, the protruding structure 21 has an extended state and a reset state. When installation is required, the protruding structure 21 is in the extended state for locking, and when disassembly is required, the protruding structure 21 is in the non-extended state, which does not affect the unscrewing of the locking nut 20. For example, the protruding structure 21 can be a push-pull block, which can be pushed in and pushed out, thereby switching between the extended state and the reset state.

[0067] In some embodiments, please refer to Figure 2 and Figure 3 The protruding structure 21 includes a fixing pin 22 and a spring 23. One end of the spring 23 abuts against the placement hole 24, and the other end abuts against the fixing pin 22.

[0068] This embodiment provides a specific method for making the protruding structure 21 have an extended state and a reset state, which is achieved by using a fixing pin 22 and a spring 23. The setting of the spring 23 can make the fixing pin 22 automatically be in the extended state, thereby achieving a better locking effect. When disassembly is required, it can be manually reset.

[0069] In some embodiments, the retaining pin has a circumferentially open receiving groove, and a spring is sleeved outside the retaining pin, with one end of the spring abutting the bottom of the receiving groove and the other end abutting the placement hole.

[0070] In some specific embodiments, the retaining pin 22 has a receiving groove 25 for placing the spring 23, with the spring 23 sleeved on the retaining pin 22 and its end abutting against the bottom of the receiving groove 25. Compared to a solution where the spring 23 directly abuts against the end of the retaining pin 22, this solution allows for more stable placement of the spring 23, a more balanced force output by the spring 23, a higher degree of locking in the extended state, and less bending of the compressed posture of the spring 23 in the reset state.

[0071] In some embodiments, the placement hole has a first region and a second region, the diameter of the first region is larger than the diameter of the second region, the receiving groove is located in the first region, one end of the spring abuts against the bottom of the receiving groove, and the other end abuts against the step surface between the first region and the second region.

[0072] In some more specific embodiments, the placement hole 24 is a through hole with two regions of different diameters. The receiving groove 25 is located in the region with the larger diameter. One end of the spring 23 abuts against the bottom of the receiving groove 25, and the other end abuts against the bottom of the region with the larger diameter. Meanwhile, the fixing pin 22 and the locking nut 20 are threadedly connected, and the threaded connection is located in the region with the smaller diameter of the receiving groove 25.

[0073] In some embodiments, the placement hole is a through hole, and the fixing pin is threadedly connected to the lock nut at the location of the first region.

[0074] It should be noted that when the retaining pin is located in the first area and threadedly connected to the locking nut, the position of the retaining pin can be precisely defined, and the locking effect is better than when a spring is used alone, achieving a multiple locking function. Furthermore, the placement hole is a through hole because one end of the through hole needs to allow the retaining pin to extend and return, while the other end needs to allow the operator to use disassembly tools to screw the retaining pin in and out.

[0075] In some embodiments, the placement hole is a through hole, and the protruding structure includes a retaining pin, which is threadedly connected to the placement hole.

[0076] The retaining pin 22 and the locking nut 20 are threaded together, and the extended and reset states are achieved by screwing them in and out. In addition, the placement hole is a through hole, because one end of the through hole needs to allow the retaining pin to extend and reset, and the other end needs to allow the operator to screw the retaining pin in and out using disassembly and assembly tools.

[0077] To address the need for modular installation of some components in automatic cooking machines due to installation and disassembly requirements, and the defect that locking units are prone to loosening and affecting the normal use of components, this utility model proposes a cooking robot.

[0078] The technical solution adopted by this utility model is a cooking robot, which includes the locking unit mentioned above.

[0079] In some embodiments, the stirring element 40 and the limiting block 10 are integrally formed, and the stirring element 40 is mounted on the rotating shaft.

[0080] In some embodiments, the limiting block 10 has an extended grip portion, which facilitates the operator's gripping for installation and disassembly, and the grip portion can participate in stirring to achieve a better stirring effect.
