Description

Technical Field

[0001] This utility model relates to a hand-grind coffee machine, and more particularly to a foldable handle assembly and the hand-grind coffee machine thereof. Background Technology

[0002] In the design of handle components, especially in manual grinding equipment such as hand-cooked coffee grinders, the structural design of the handle significantly impacts the ease of use and space utilization. Existing technologies have shortcomings in the use and storage of some hand-cooked coffee grinder handles. For example, the "A Portable Hand-Cooked Coffee Grinding Machine Telescopic Handle" (publication number CN214341912U) uses a crank handle to extend and retract within the handle cavity of the crank arm, and is fixed by the cooperation of a locking pin and a locking slot. While this achieves a certain degree of telescopic function, there is still room for improvement in the folding method and structural stability. This telescopic structure mainly relies on the cooperation of the sliding groove and the locking slot to adjust the handle length. When folded for storage, the handle still maintains a certain straight extension with the main body, failing to achieve complete folding and storage. For space-constrained scenarios, its space-saving effect is not ideal, and after long-term use, the cooperation between the locking pin and the locking slot may wear down, leading to decreased stability and affecting the user experience. Therefore, there is an urgent need for a new type of foldable handle component to better solve the problems of space occupation and structural stability of existing handles. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a foldable handle assembly and a hand-grinding coffee machine thereof.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0005] A foldable handle assembly, comprising:

[0006] The conduit has a first guide hole in its axial direction;

[0007] The folding arm is pushed into the conduit along the first guide hole, and the folding arm is connected to the conduit by a component; when the folding arm is pulled out along the first guide hole, the folding arm is hinged to the conduit by a pin.

[0008] Preferably, the components are connected by magnetic attraction.

[0009] Preferably, a first magnet is fixed to the end of the folding arm, and a second magnet is fixed to the inner end of the first guide hole. The folding arm is magnetically connected to the second magnet inside the guide tube through the first magnet.

[0010] Preferably, the component connection is a hook connection.

[0011] Preferably, the component connection is a snap-fit ​​connection.

[0012] Preferably, a second guide hole is symmetrically provided on the inner wall of the first guide hole, the second guide hole is connected to the first guide hole, and the pin on the end of the folding arm moves along the second guide hole.

[0013] Preferably, the outer end of the catheter has a notch, through which the folding arm folds onto the catheter.

[0014] Preferably, the outer end of the catheter is provided with a window, which is positioned opposite to the notch. When the folding arm is folded onto the catheter, the inner end of the folding arm rotates to the window.

[0015] Preferably, the other end of the folding arm has an upwardly bent handle arm with a rotating handle mounted on it.

[0016] A hand-grinding coffee machine includes a body with a foldable handle assembly mounted on it. The end of a conduit is connected to the body and drives the machine to grind coffee. A folding arm folds downward through the conduit and is positioned on the side of the body.

[0017] This utility model, by adopting the above technical solution, has significant technical effects:

[0018] On the one hand, when the folding arm is pushed into the conduit along the first guide hole of the conduit, the folding arm and the conduit are firmly connected by the component connection. This connection method can ensure that the two are tightly connected when the folding arm drives the conduit to rotate together, reducing relative shaking or separation, and improving the stability and reliability of the overall structure in working condition.

[0019] On the other hand, when the folding arm is pulled outward along the first guide hole, it is hinged to the guide tube by a pin, realizing the folding function. This design not only meets the linkage requirements of both when working, but also changes the shape by folding when not working, increasing the flexibility of use. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail with reference to the embodiments.

[0030] Example 1

[0031] A foldable handle assembly includes a guide tube 1 and a folding arm 2. The guide tube 1 has a first guide hole 11 in its axial direction. When the folding arm 2 is pushed into the guide tube 1 along the first guide hole 11, the folding arm 2 and the guide tube 1 are connected by a component, which is a magnetic connection. When the folding arm 2 is pulled outward along the first guide hole 11, the folding arm 2 is hinged to the guide tube 1 by a pin 3. The component connection when the folding arm 2 is pushed into the guide tube 1 ensures a tight connection between the two during linkage rotation, reducing relative wobbling or disengagement and ensuring stability during operation. By pushing and pulling the folding arm 2 along the first guide hole 11, the two states of linkage and hinged folding can be quickly switched, satisfying the linkage requirements during operation and facilitating folding when not in operation, thus improving the flexibility of use.

[0032] When the foldable handle assembly is in operation, if the folding arm 2 needs to rotate in conjunction with the conduit 1, the folding arm 2 is pushed into the conduit 1 along the first guide hole 11 along the axis of the conduit 1. At this time, the folding arm 2 and the conduit 1 are connected by magnetic attraction to form an integral structure. The user can operate the folding arm 2 to drive the conduit 1 to rotate synchronously. When no linkage rotation is required and folding is needed for storage, the folding arm 2 is pulled outward along the first guide hole 11. The folding arm 2 is then hinged to the conduit 1 by the pin 3 to realize the folding function and change the relative position of the two.

[0033] A first magnet 4 is fixed to the end of the folding arm 2, and a second magnet 5 is fixed to the inner end of the first guide hole 11. The folding arm 2 is magnetically connected to the second magnet 5 inside the conduit 1 via the first magnet 4. The magnetic connection means that the connection and separation of the folding arm 2 and the conduit 1 can be completed without complicated operations, simply by pushing and pulling the folding arm 2 along the first guide hole 11. Combined with the hinge function of the pin 3, the switching between the component in linkage operation and folding state is smoother, enhancing the convenience of use.

[0034] Symmetrically arranged second guide holes 12 are provided on the inner wall of the first guide hole 11. The second guide hole 12 is a through hole extending from one end of the guide tube 1 to the other end, and it communicates with the first guide hole 11. The pin 3 on the end of the folding arm 2 moves along the second guide hole 12. The cooperation between the pin 3 and the second guide hole 12 can form a circumferential limit on the folding arm 2, effectively preventing the folding arm 2 from rotating within the guide tube 1, ensuring that the folding arm 2 maintains a stable posture during pushing and pulling and when it is linked with the guide tube 1, avoiding connection misalignment or operational deviation caused by rotation. The second guide hole 12 provides a clear trajectory for the movement of the pin 3, thereby guiding the folding arm 2 to push and pull smoothly along a preset path, reducing jamming or deviation during movement, and improving the smoothness and reliability of the overall movement of the component. The cooperation between the pin 3 and the second guide hole 12 not only realizes the anti-rotation function, but also enhances the connection strength between the folding arm 2 and the guide tube 1, making the force on both more balanced in relative movement and engagement, reducing the risk of local wear, and helping to extend the service life of the component.

[0035] The outer end of the conduit 1 is provided with a notch 13. The folding arm 2 is folded onto the conduit 1 through the notch 13. The notch 13 at the outer end of the conduit 1 provides a dedicated space for the folding movement of the folding arm 2. When the folding arm 2 is hinged onto the conduit 1 through the pin 3 and folded, the notch 13 can accommodate part of the structure of the folding arm 2, avoiding structural interference between the folding arm 2 and the conduit 1 during the folding process, and ensuring that the folding action can be completed smoothly.

[0036] The outer end of the conduit 1 is also provided with a window 14, which is positioned opposite to the notch 13. When the folding arm 2 is folded onto the conduit 1, its inner end rotates to the window 14. The window 14, which is opposite to the notch 13, provides a space for the inner end of the folding arm 2 when it is folded onto the conduit 1, effectively preventing structural interference between the folding arm 2 and the conduit 1 during the folding process and ensuring the smooth completion of the folding action.

[0037] The other end of the folding arm 2 is provided with an upwardly bent handle arm 21, on which a handle 6 is mounted and can rotate. The handle arm 21 provides a dedicated mounting carrier for the handle 6, allowing the handle 6 to be stably mounted on the folding arm 2. The handle 6 is designed to conform to human grip habits, making it convenient for users to hold firmly and apply force more effectively during operation. It also facilitates the circular motion of the folding arm 2 and the connected guide tube 1 through the handle 6, improving the convenience and efficiency of operation.

[0038] Example 2

[0039] Example 2 is basically the same as Example 1, except that the component connection is a hook connection, which is a Velcro connection.

[0040] Example 3

[0041] Example 3 is basically the same as Example 1, except that the component connection is a snap-fit ​​connection, which is a press-type buckle. When the folding arm 2 is pushed into the conduit 1, the folding arm 2 is pressed down to connect with the conduit 1. When the folding arm 2 is pressed down again, the two will separate.

[0042] Example 4

[0043] A hand-grinding coffee machine includes a body 7, on which a foldable handle assembly as described in embodiment 1, 2, or 3 is mounted. The end of a conduit 1 is connected to the body 7 and drives the body 7 to grind. A folding arm 2 is folded downward through the conduit 1 and positioned on the side of the body 7.
