Description

Technical Field

[0001] The utility model relates to the field of hand-cranked grinders for convenient external adjustment, and particularly to an externally adjustable hand-cranked grinder. Background Art

[0002] The hand-cranked grinder is a classic coffee grinding method. Initially, the coffee beans were ground into particles by the ancient millstone technology. With the progress of technology, different coffee particles can be ground for different groups, enabling the coffee to have different tastes. And with the progress of technology, the current hand-cranked grinders are extremely convenient to carry and are favored by many coffee lovers.

[0003] For the existing externally adjustable hand-cranked grinders on the market, it takes cumbersome steps to disassemble them for internal cleaning after use. This causes users to reduce the frequency of internal cleaning of the device, which will allow bacteria to grow inside the device. Therefore, the utility model provides an externally adjustable hand-cranked grinder to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an externally adjustable hand-cranked grinder. This device is convenient for disassembling the internal parts and increases the convenience of internal cleaning of the device.

In this way, when the device is not in use, it can be slid and folded through the sliding block 11, reducing the space occupied during the storage of the device. Then, the sliding groove 13 inside the front connecting block 12 is connected to the fixed block 10 and the sliding block 11 on the rear connecting block 9, enabling the sliding block 11 to slide and rotate within the sliding groove 13, facilitating its folding and storage and increasing the convenience during the storage of the device.

[0042] An extension block 23 is sleeved on the outer surface of the connecting shaft 6 near the lower end face. A scale block 24 is fixedly arranged on the lower end face of the extension block 23. Two docking connection blocks 25 are arranged on the outer surface of the scale block 24. Rotating blocks 26 are fixedly arranged on the opposite sides of the two docking connection blocks 25. A threaded hole 27 is opened in the middle of the lower end face of the scale block 24. A plurality of clamping blocks 28 are arranged on the lower end faces of the rotating blocks 26. A collection box 29 is arranged on the lower end face of the rotating block 26. A plurality of clamping grooves 30 are opened on the upper end face of the collection box 29. The plurality of clamping blocks 28 are clamped with the clamping grooves 30. A threaded block 31 is fixedly arranged on the outer surface of the connecting shaft 6 near the lower end face. The threaded block 31 is threadedly arranged with the threaded hole 27;

[0043] An extension block 23 is installed on the connecting shaft 6, and the docking connection block 25 on the scale block 24 is connected to the rotating block 26. When twisting the rotating block 26, it can drive the stabilizing block 22 and the rotating grinder 18 to move upward, facilitating the fine adjustment of the parts inside the device and enabling the coffee beans to be ground into the desired particle shape. There are clamping blocks 28 below the rotating block 26. The clamping blocks 28 can be first inserted into the clamping grooves 30 on the upper surface of the collection box 29, and then the collection box 29 is rotated to make the clamping blocks 28 snap into the inside of the clamping grooves 30, which is convenient for its disassembly and installation and increases the convenience during the use of the device. There is a threaded hole 27 in the rotating block 26 and a threaded block 31 on the connecting shaft 6. When using the device, the threaded hole 27 can be moved up and down on the threaded block 31 by rotating the rotating block 26, facilitating the adjustment of the inside of the device.

[0044] Working principle: When using this device, first twist the rotating block 26 to make the stabilizing block 22 push the rotating grinder 18 upward, increasing the gap between the rotating grinder 18 and the fixed grinder 15 inside the protective shell 1, so that the particle size of the coffee beans during grinding becomes larger. The rotating block 26 is set on the outer surface of the device for convenient adjustment of the particle size during grinding. Then remove the rotating cover 7, put the coffee beans into the protective shell 1 from above, and after putting them in, install the rotating cover 7 onto the connecting shaft 6 through the fixing groove 8. Then rotate the hand crank block 14, and the rear connecting block 9 and the front connecting block 12 will drive the connecting shaft 6 to drive the rotating grinder 18 to rotate and crush the coffee beans. The crushed particles will fall into the collection box 29. By rotating the collection box 29, the clamping block 28 in the clamping groove 30 on the collection box 29 is released from the buckle, and then the collection box 29 can be removed to pour out the coffee inside. After use, the rotating block 26 can be rotated multiple times and removed, and then the parts inside the device can be taken out to clean the inside of the device. Then, through the sliding block 11 in the sliding groove 13 of the front connecting block 12, the front connecting block 12 can be folded and stored, which is convenient for disassembling and storing the device after use, reducing the space required for placing the device.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
