Description

Shaft device

[technical field]

The utility model relates to a rotating shaft device, in particular to a rotating shaft device for enabling a first object to pivot and position relative to a second object.

[Background technique]

Referring to FIG. 1 , it is a conventional hinge device (commonly known as a hinge) used at a hinge of a notebook computer, which generally includes a first shaft 91 and a second shaft 92 . Wherein, the first shaft member 91 has a fixed piece 911 and a sleeve 912 connected to the right side of the fixed piece 911 . The second shaft 92 includes a rotating shaft 921 corresponding to the sleeve 912, a limiting block 922 connected to the right side of the rotating shaft 921, and a fixed piece 923 integrally formed on the right side of the limiting block 922; the rotating shaft 921 has several turns A ring groove 924 is formed around the outer surface thereof.

During use, it is necessary to apply lubricant on the ring groove 924 of the rotating shaft 921 in advance, and then insert the rotating shaft 921 into the sleeve 912 until the sleeve 912 reaches the left side of the blocking block 922 . Next, the fixing pieces 911 , 923 of the two shaft members 91 , 92 are respectively fixed to the sides of the first object and the second object to be pivotally connected in a screw lock manner. In this way, the two connected objects can be relatively pivoted by means of the rotating shaft device.

However, due to the following deficiencies of the rotating shaft device, its usability is poor:

(1) Difficulty in processing: because the rotating shaft 921 and the ring groove 924 of the second shaft member 92 are all processed by a lathe; especially in the making of the ring groove 924, it needs to chisel several turns at the free end of the rotating shaft 921, which is very difficult. It is not easy to process, and the rotating shaft 921 is easily broken and damaged due to excessive stress in the process of processing.

(2) The rotating shaft device cannot be standardized: because the existing rotating shaft device is assembled together by simple fitting, and the torsion between the sleeve 912 and the rotating shaft 921 enables the two objects to rotate relatively within a certain range. Therefore, the designer must change the specifications of the sleeve 912 and the shaft 921 for devices with different pivoting angles, so as to change the torque value accordingly, so it is impossible to standardize the production of the shaft device. To sum up, the conventional rotating shaft device has poor usability and poor design flexibility.

The positioning part includes a second fixing part which can be fixed on the second object, a sleeve part, and a middle part connecting the sleeve part and the second fixing part. The friction member includes a sleeve part that can be fitted tightly outside the shaft part and can be correspondingly fixed inside the sleeve part.

The beneficial effect of the utility model is that: the mechanism design of the friction part with the rotating shaft part and the positioning part makes the utility model have the advantages of simple assembly and convenient processing, and is not easy to be damaged due to the stress generated in the processing process, so , not only can save costs, but is also suitable for automatic assembly operations: in addition, the utility model shaft device also has the advantage of standardized production of parts, and at the same time can improve the product quality of the utility model shaft device.
