Description

Shaft with anti-shake function

technical field

The utility model relates to a rotating shaft, in particular to a rotating shaft with the functions of anti-shaking and anti-oil leakage.

Background technique

According to general consumer electronic products with a flip cover, such as portable computers, mobile phones, electronic dictionaries and portable audio-visual playback devices, etc., the main body is generally placed in the lower half, and the hinge is connected to the upper half of the cover. The body part is connected so that the cover body part can be opened and closed relative to the main body part. Therefore, the rotating shaft is a major factor in determining the quality of the above-mentioned products.

For example, China Taiwan Patent Announcement No. 420321 discloses a "two-way positioning hinge structure". The fixing seat of the hinge is made of metal castings. In order to increase its wear resistance, a combination The hole is connected with the I-shaped groove at the end of the combination hole, so that a plurality of pipe spring holders can be inserted into the combination hole, and the ends formed by the bottom of the pipe spring holder at intervals are positioned in the I-shaped groove. . In addition, the shaft rod of a pivot is passed through the shaft hole in the center of the plurality of pipe spring frames to form a hinge structure. The combination of the fixed base of the hinge and a plurality of pipe spring frames does provide a fixing method between soft metal castings and hard friction pipe spring frames.

In order to prevent the lubricating oil between the spring frame and the shaft from seeping or leaking from the opening of the joint hole, so as to be contaminated with dirt and affect the pivoting of the rotating shaft. The more obvious disadvantage is that because the spring frame is formed by bending metal, its transverse opening is not a true circle, so that when the shaft of the pivot pivots in the opening of the spring frame, it will shake. , which in turn causes increased wear between the two components, which is a fly in the ointment.

Such as China Taiwan Patent Announcement No. M296583 promptly discloses a kind of " hinge device ", and this hinge device comprises the fixing seat that has combining hole, reed pipe, passes through reed pipe and puts in the combining hole of fixing seat together with it. Pivot; Wherein, the pivot is provided with a sealing piece, the outside of the sealing piece is provided with a positioning block, and the center is provided with a perforation for the pivot to pass through. The inner diameter of the perforation is not greater than the outer diameter of the pivot. The opening of the joint hole of the fixing seat is provided with a positioning groove for the positioning block of the sealing plate of the pivot to be embedded and positioned. Therefore, the sealing piece is inserted into the joint hole of the fixing seat to prevent the leakage of lubricating oil, and the round hole-shaped perforation allows the pivot to pass through tightly, so as to prevent the pivot from shaking when pivoting. Certainly, aforementioned patent case can obtain the effect of anti-sloshing and oil leakage. However, in consideration of the manufacturing and assembly process, the positioning block protruding from the periphery of the sealing piece must coincide with the positioning groove corresponding to the coupling hole, which not only increases the precision between the two components, but also makes assembly difficult . In particular, the sealing piece is only coupled to the coupling hole of the fixing base by inserting, if the tightness between the two is not good, the anti-shaking function will be lost. Therefore, how to firmly combine the sealing sheet with the opening end of the coupling hole is a difficult problem to be overcome urgently by the relevant industry.
