Technical Field
The present invention relates to a coupling structure, and more particularly, to a coupling structure of a base and a shaft tube.
Background
Referring to fig. 1, there is shown an exploded view of a known base and shaft tube. The known base-shaft tube combination 10 includes a base 11 and a shaft tube 12. The base 11 has a shaft seat 111 for receiving the shaft tube 12. In order to firmly couple the shaft tube 12 into the shaft seat 111, the inner diameter of the inner surface of the shaft seat 111 is generally smaller than the outer diameter of the shaft tube 12, so that the shaft tube 12 can be fixed in the shaft seat 111 by strong pressing.
However, since the base 11 is usually made of plastic and the shaft tube 12 is usually made of metal, the shaft seat 111 is sometimes broken during the process of strong pressing and combining, which results in a decrease in product yield. Furthermore, under the requirement of decreasing the size of the components, the length of the shaft seat 111 extending upward is reduced, so that the combination area of the shaft seat 111 and the shaft tube 12 is reduced, and the shaft tube 12 cannot be stably fixed to the shaft seat 111 of the base 11 because the base 11 and the shaft tube 12 are made of different materials.
Therefore, there is a need to provide an innovative and advanced combination structure of a base and a shaft tube to solve the above problems.

Alternatively, the inner diameter of the ring groove 222 is smaller than the outer diameter of the metal collar 23, so that the metal collar 23 is strongly press-fitted into the ring groove 222, thereby firmly fixing the metal collar 23 in the ring groove 222.
In addition, for assembly, the ring groove 222 is disposed at the bottom of the base 22, so that the metal collar 23 can be disposed in the ring groove 222 from the bottom of the base 22.
After the metal collar 23 is disposed in the ring groove 222, the shaft tube 21 is disposed in the shaft seat 221 of the base 22 and the metal collar 23, in this embodiment, the shaft tube 21 is a metal shaft tube, and the shaft tube 21 is a blind shaft tube having a closed bottom 211. The inner diameter of the inner surface of the shaft seat 221 and the inner diameter of the metal collar 23 are both smaller than the outer diameter of the shaft tube 21, so that the shaft tube 21 is strongly pressed and combined into the shaft seat 221 of the base 22 and the metal collar 23, and the shaft tube 21 is firmly fixed in the shaft seat 221 of the base 22 and the metal collar 23. Moreover, the metal collar 23 can be a copper collar, and since the metal collar 23 and the shaft tube 21 are made of metal, the shaft tube 21 can be further fixed in the metal collar 23, so as to enhance the bonding force between the shaft tube 21 and the base 22.
In addition, in the process of strong pressing and combining, the metal lantern ring 23 can avoid the situation that the shaft seat 221 is broken, so as to improve the qualification rate of products.

The base 32 has a shaft seat 321 for receiving the shaft tube 31, and the inner surface of the shaft seat 321 has a ring groove 322. The metal collar 33 is disposed in the ring groove 322 for receiving the shaft tube 31.
The base and axle tube combination structure 30 of the second embodiment of the present invention is different from the base and axle tube combination structure 20 of the first embodiment of the present invention in that the axle tube 31 is a non-blind axle tube, i.e. two ends of the axle tube 31 are connected to form a through hole.
Referring to fig. 5 again, the base and shaft tube combination structure 30 of the second embodiment of the present invention can be applied to a fan 50, except for the shaft tube 31, the base 32 and the metal collar 33, a bearing 34 is disposed in the shaft tube 31, a spindle 351 of a fan wheel 35 is disposed in the bearing 34, the fan wheel 35 further includes a magnet 352 and a blade 353, a coil and a circuit board 36 are disposed outside the shaft tube 31, a top cover 37 is disposed in the bottom of the shaft tube 31 for sealing the bottom of the shaft tube 31, and a wear-resistant sheet 38 is disposed on the top cover 37 in the shaft tube 31, so that the top of the spindle 351 of the fan wheel 35 abuts against the wear-resistant sheet 38.
Therefore, the base-shaft tube combination structure 30 of the second embodiment of the present invention can firmly fix the shaft tube 31 in the shaft seat 321 of the base 32 and the metal collar 33, and can prevent the shaft seat 321 from being broken, thereby facilitating assembly and combination of other elements of the fan 50 and improving the yield of the fan 50.
