Description

Technical Field

[0001] This invention relates to the technical field of mixers, and in particular to a split-type transmission locking connection structure and its locking and unlocking method. Background Technology

[0002] In existing technologies, split-type transmission connection structures are widely used in household appliances, industrial equipment, and daily necessities to achieve power transmission between fixed and detachable components. Current mainstream designs primarily rely on vertical plug-in connections or straight-line push-in methods with a fixed tilt angle. While these structures can achieve basic transmission functions, they have several significant drawbacks: First, in terms of spatial layout, the vertical or oblique straight-line connection path directly occupies the top area of ​​the container, preventing the installation of other functional components (such as displays, control panels, water inlets, lighting modules, etc.) in that location. This severely limits the product's functional integration and aesthetic design diversity, reducing overall space utilization and product added value. Second, regarding user operation, existing connection methods require users to precisely position and align the container, especially when visibility is obstructed or operating space is limited. The connection process is cumbersome and prone to failure, resulting in a poor user experience. Frequent alignment attempts may also accelerate the wear of transmission components, affecting structural lifespan. Furthermore, most existing structures do not adequately consider connection reliability, often lacking an effective automatic locking mechanism, or having a complex and inconvenient locking mechanism design. Some products use additional independent locking mechanisms, requiring both hands to perform the docking and locking operations, which is cumbersome; and when unlocking and removing them, there are also problems with disjointed operation and effort. Summary of the Invention

[0003] In order to overcome the existing technical defects, the purpose of this invention is to provide a split-type transmission locking connection structure and its locking and unlocking method to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this invention to solve the technical problem is as follows:

[0005] According to one aspect of the present invention, a split-type transmission locking connection structure is designed, comprising: a main body with a lower transmission wheel; a container with an upper transmission wheel; a bidirectional inclined rail on the main body, including a connected ascending section and a descending section; a sliding structural member on the container, which slides in cooperation with the bidirectional inclined rail, for guiding the upper transmission wheel to first rise along the ascending section to align with the axis of the lower transmission wheel, and then descend along the descending section to complete the docking when the container is pushed in; an automatic locking mechanism between the main body and the container, for automatically locking after the upper transmission wheel and the lower transmission wheel have docked; and an unlocking mechanism on the container, for manually releasing the locking state of the automatic locking mechanism to allow the container to be pulled out.

[0006] In some embodiments, a first card holder is provided at the lower part of the main body, the lower drive wheel is inclinedly disposed on the first card holder, and the upper drive wheel is inclinedly disposed at the bottom of the container; there are two bidirectional inclined guide rails, which are respectively disposed on the left and right sides of the first card holder.

[0007] In some embodiments, the overall profile of the bidirectional ramp guide rail is inverted V-shape or inverted U-shape.

[0008] In some embodiments, the sliding structure is a slider, a roller, or a guide post.

[0009] In some embodiments, the front side of the first card holder is provided with a card slot, and the automatic locking mechanism includes a pair of spring posts, which are respectively disposed on the left and right sides of the card slot; the bottom of the container is provided with a card hole that matches the spring posts.

[0010] In some embodiments, the unlocking mechanism includes:

[0011] A pinch handle, hinged to the inside of the container's handle;

[0012] The second card holder is located at the bottom of the container, and the card holes are located on both sides of the second card holder;

[0013] The connecting rod is rotatably disposed in the second card holder, and its upper end is in active contact with the pinch handle;

[0014] A reset torsion spring is sleeved between the connecting rod and the second retainer;

[0015] The movable block is movably disposed within the second card holder and movably contacts the lower end of the connecting rod;

[0016] A pair of ejector pins are respectively located on both sides of the movable block and are movably inserted into the corresponding locking holes for contacting the ends of the spring pins.

[0017] In some embodiments, the end of the spring post includes an insertion part and a pressing part coaxially arranged, the length of the insertion part being greater than that of the pressing part; when in the locked state, the insertion part extends into the rear side of the locking hole, and the pressing part abuts against the ejector post located in front of the locking hole; when the handle is pressed, the connecting rod pushes the movable block and the ejector post to move backward, pushing the spring post out of the locking hole.

[0018] A locking and unlocking method for a split-type transmission locking connection structure includes the following steps:

[0019] Locking Step: Push the container toward the main body in the pushing direction, so that the sliding structure on the container moves along the bidirectional inclined guide rail on the main body. First, the upper drive wheel is guided to rise through the rising section until it is aligned with the axis of the lower drive wheel. Then, the upper drive wheel is guided to descend through the descending section until it docks with the lower drive wheel. When docking is completed, the automatic locking mechanism is automatically activated to lock the container to the main body.

[0020] Unlocking steps: Operate the unlocking mechanism on the container to release the locking state of the automatic locking mechanism; while maintaining the unlocking operation, remove the container from the main body in the pulling direction, and the sliding structure moves in the opposite direction along the bidirectional inclined guide rail, causing the upper transmission wheel to separate from the lower transmission wheel.

[0021] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] This invention achieves automatic lifting, centering, and lowering docking during the container's push-pull process through the cooperation of a bidirectional inclined guide rail and a sliding structural component. The operation is smooth and does not require precise alignment. This design allows the docking action to occur on the side of the container, completely freeing up its top space for easy installation of other functional components. The integrated automatic locking mechanism can lock instantly after docking, ensuring a stable and reliable transmission connection. The unlocking mechanism located at the handle is ergonomic, with a natural and smooth pinching action, enabling one-button unlocking and removal. The overall structure is ingenious, greatly improving ease of use, space utilization, and connection security. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0033] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0035] refer to Figures 1 to 9 As shown, the present invention provides a split-type transmission locking connection structure, comprising: a main body 1 with a lower transmission wheel 2; a container 3 with an upper transmission wheel 4; a bidirectional inclined rail 5 disposed on the main body 1, including a connected rising section 6 and a descending section 7; a sliding structural member 8 disposed on the container 3, slidingly engaging with the bidirectional inclined rail 5, for guiding the upper transmission wheel 4 to first rise along the rising section 6 to align with the axis of the lower transmission wheel 2, and then descend along the descending section 7 to complete the docking when the container 3 is pushed in; an automatic locking mechanism disposed between the main body 1 and the container 3, for automatically locking after the upper transmission wheel 4 and the lower transmission wheel 2 have docked; and an unlocking mechanism disposed on the container 3, for manually releasing the locking state of the automatic locking mechanism to allow the container 3 to be pulled out. Through the ingenious cooperation of the bidirectional inclined rail 5 and the sliding structural member 8, a semi-automatic path of "first rising to align, then descending to dock" is achieved during the pushing process of the container 3. Users can easily complete complex spatial positioning and transmission connections by simply pushing and pulling, which greatly reduces the difficulty of operation. At the same time, it completely avoids the occupation of the top space of container 3 by the traditional vertical docking method, freeing up design space for the integration of other functional modules (such as display screen and water inlet).

[0036] In some embodiments, a first mounting base 9 is provided at the lower part of the main body 1, the lower transmission wheel 2 is inclinedly mounted on the first mounting base 9, and the upper transmission wheel 4 is inclinedly mounted on the bottom of the container 3; two bidirectional inclined guide rails 5 are provided, respectively on the left and right sides of the first mounting base 9. By inclinedly mounting the lower transmission wheel 2 on the first mounting base 9 and correspondingly mounting the upper transmission wheel 4 on the bottom of the container 3, the transmission wheel system obtains a better meshing angle within a limited height. The bidirectional inclined guide rails 5 symmetrically arranged on both sides ensure that the container 3 is subjected to balanced force when pushed in, guiding it smoothly and effectively preventing alignment errors caused by unilateral jamming, thereby improving the accuracy and reliability of transmission docking.

[0037] In some embodiments, the overall profile of the bidirectional ramp guide rail 5 is an inverted V-shape or an inverted U-shape. The inverted V-shape or inverted U-shape guide rail profile has a smooth transition between its rising section 6 and descending section 7, forming a continuous guide surface without abrupt changes. This design ensures smooth and shock-free movement of the sliding structural component 8, allowing the lifting, centering, lowering, and docking processes of the container 3 to be completed seamlessly. This not only optimizes the user experience but also reduces wear and noise during component movement.

[0038] In some embodiments, the sliding structure 8 is a slider, a roller, or a guide post. Providing different forms of sliding structure 8, such as sliders, rollers, or guide posts, enhances the flexibility and adaptability of the design. For example, rollers significantly reduce friction, making pushing and pulling easier; sliders, on the other hand, have a simple structure and low cost. Users can choose the most suitable solution based on the load-bearing capacity, usage frequency, and cost requirements of the specific product, achieving an optimal balance between performance and cost.

[0039] In some embodiments, the front side of the first card holder 9 is provided with a card slot 10, and the automatic locking mechanism includes a pair of spring posts 11, which are respectively disposed on the left and right sides of the card slot 10; the bottom of the container 3 is provided with a locking hole 12 that matches the spring posts 11. The locking method, which uses a pair of spring posts 11 disposed on both sides of the card slot 10 to engage with the locking hole 12 at the bottom of the container 3, is simple, reliable, and has low manufacturing cost. This mechanism can automatically engage the spring posts 11 into the locking hole 12 by means of spring force the moment the container 3 is pushed into place, achieving instantaneous and stable mechanical locking without requiring additional action from the user, thus ensuring the safety and stability of the transmission connection during operation.

[0040] In some embodiments, the unlocking mechanism includes:

[0041] The handle 13 is hinged to the inside of the handle 14 of the container 3;

[0042] The second card holder 15 is located at the bottom of the container 3, and the card holes 12 are located on both sides of the second card holder 15;

[0043] The connecting rod 16 is rotatably disposed in the second card seat 15, and its upper end is in active contact with the pinch handle 13;

[0044] A reset torsion spring 17 is sleeved between the connecting rod 16 and the second retainer 15;

[0045] The movable block 18 is movably disposed within the second card holder 15 and is in movable contact with the lower end of the connecting rod 16;

[0046] A pair of ejector pins 19 are respectively disposed on both sides of the movable block 18 and are movably inserted into the corresponding locking holes 12 for contacting the end of the spring pin 11.

[0047] The unlocking mechanism converts the pressing force of the handle 13 into the movement of the ejector pin 19 via the connecting rod 16 and the movable block 18, achieving an intuitive linkage between "squeezing" and "unlocking," which is ergonomic. The reset torsion spring 17 ensures that all components automatically reset after the handle 13 is released, preparing for the next locking action. The entire mechanism is integrated inside the container 3, with a simple appearance and clear, consistent operation, allowing for unlocking and removal with just one hand.

[0048] In some embodiments, the end of the spring post 11 includes a coaxially arranged insertion portion 20 and a pressing portion 21, the length of which is greater than that of the pressing portion 21. When in the locked state, the insertion portion 20 extends into the rear side of the latch hole 12, and the pressing portion 21 abuts against the ejector post 19 located in front of the latch hole 12. When the handle 13 is pressed, the connecting rod 16 pushes the movable block 18 and the ejector post 19 backward, ejecting the spring post 11 out of the latch hole 12. The design of the spring post 11's end being divided into a long insertion portion 20 and a short pressing portion 21 ensures that, in the locked state, the insertion portion 20 penetrates deep into the latch hole 12 to provide the main holding force, while the pressing portion 21 only lightly touches the ejector post 19. This structure ensures both the stability of the lock (the insertion part 20 provides tensile strength) and the fact that when unlocking, the ejector post 19 only needs to overcome the small spring resistance of the pressing part 21 to push out the entire spring post 11, thereby achieving the effect of "unlocking with small operating force and locking with large force", making unlocking easier and more reliable.

[0049] In some embodiments, the end of the bidirectional ramp guide rail 5 is provided with a pressure plate 22 at an angle to prevent the container 3 from coming out at an angle greater than that of the pressure plate.

[0050] A locking and unlocking method for a split-type transmission locking connection structure includes the following steps:

[0051] Locking Step: Push the container 3 toward the main body 1 in the pushing direction, so that the sliding structure 8 on the container 3 moves along the bidirectional inclined guide rail 5 on the main body 1. First, the upper transmission wheel 4 is guided to rise through the rising section 6 until it is aligned with the axis of the lower transmission wheel 2. Then, the upper transmission wheel 4 is guided to descend through the descending section 7 until it docks with the lower transmission wheel 2. When docking is completed, the automatic locking mechanism is automatically activated to lock the container 3 to the main body 1.

[0052] Unlocking steps: Operate the unlocking mechanism on the container 3 to release the locking state of the automatic locking mechanism; while maintaining the unlocking operation, remove the container 3 from the main body 1 in the pulling direction, and the sliding structure 8 moves in the opposite direction along the bidirectional inclined guide rail 5, causing the upper transmission wheel 4 to separate from the lower transmission wheel 2.

[0053] This method simplifies the complex spatial docking and locking process into an intuitive "push to engage, squeeze to disengage" operation, greatly improving user-friendliness. Automated guidance and locking of the engagement step ensure consistency in every connection; the unlocking step and retrieval action are seamlessly integrated, smooth and natural. This method is not only applicable to the specific structure described above, but its core "guide-alignment-locking" concept also provides a useful operational paradigm for other modular connection products.

[0054] During the locking process, the user smoothly pushes the container 3 towards the main body 1. The sliding structure 8 set on the container 3 then embeds into the bidirectional inclined guide rail 5 on the main body 1 and moves along the rising section 6. During this stage, the upper transmission wheel 4 at the bottom of the container 3 is raised synchronously until its rotation axis is precisely aligned with the axis of the lower transmission wheel 2 on the main body 1. Subsequently, the sliding structure 8 slides into the descending section 7 of the guide rail, guiding the upper transmission wheel 4 to descend smoothly along the aligned axis, and finally achieves a tight transmission connection with the lower transmission wheel 2. At the moment the connection is completed, the automatic locking mechanism set between the main body 1 and the container 3 is automatically triggered, which securely locks the container 3 onto the main body 1, completing the entire "push-and-lock" connection and fixation. When unlocking and removal are required, the user squeezes the handle 13 inside the handle 14 of container 3 with one hand. The connecting rod 16 and the movable block 18 drive the ejector column 19 to move backward, overcoming the holding force of the automatic locking mechanism and pushing the spring column 11 out of the locking hole 12, thereby releasing the locking state. While maintaining the squeeze, the user can pull the container 3 outward. At this time, the sliding structure 8 moves in the opposite direction along the bidirectional inclined guide rail 5, guiding the upper transmission wheel 4 to rise smoothly to disengage from the engagement, and then descend to reset, finally realizing the complete separation of container 3 from the main body 1, completing the convenient "squeeze and go" unlocking and removal operation.

[0055] This invention achieves automatic lifting, centering, and lowering docking of container 3 during the pushing and pulling process through the cooperation of bidirectional inclined guide rail 5 and sliding structural component 8. The operation is smooth and does not require precise alignment. This design allows the docking action to occur on the side of container 3, completely freeing up its top space and facilitating the installation of other functional components. The integrated automatic locking mechanism can lock instantly after docking, ensuring a stable and reliable transmission connection. The unlocking mechanism located at handle 14 is ergonomic, and the pinching action is natural and smooth, realizing one-button unlocking and removal. The overall structure is ingenious, greatly improving ease of use, space utilization, and connection security.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
