Problems solved by technology

Under normal circumstances, the average wall thickness of the plastic shell of the mobile phone is between 1.5mm and 2.5mm, but the wall thickness of the structure of the fixed shaft part of the mobile phone is 2.5mm. Part of the wall thickness exceeds the average wall thickness by 1mm, so the surface of the plastic case will shrink during injection molding and affect the appearance of the mobile phone

Abstract

The fixed structure includes shell of main body, turnable overcrust, and shaft. The shell of main body possesses first and second installation seats. The turnable overcrust possesses adaption seat (AS) loaded between first and second installation seats. First shaft hole is setup on surface of AS faced to first installation seat, and second shaft hole is setup on surface of first installation seat faced to AS. Two ends of the shaft are clearance fitted to first shaft hole and second shaft hole respectively. At least two slots for reducing materials to a smaller quantity are uniform distributed on same circle on surface of AS. Ribs separate adjacent slots, and bulkhead divides off each slot from second shaft hole along radial. Being setup on the bulkhead, notches are connected to slots and second shaft hole. The slots prevent turnable overcrust from surface shrinkage in procedure of injection molding, and ribs guarantees turnable overcrust with certain intensity.

Description

technical field [0001] The invention relates to the field of flip phones, in particular to a rotating shaft fixing structure applied to flip phones. Background technique [0002] The rotating shaft is a very important part in the field of flip phones. Without this part, the flip phone cannot be turned over normally. It is also very important to fix the rotating shaft, otherwise the phone will produce abnormal noise during the flipping process. It will cause cracks on the surface of the case, which will affect the function and appearance of the mobile phone. Since the mobile phone is a relatively high-end consumer product, the requirements for it are also very high. It has to go through various tests, and the test of the rotating shaft is even more important. Because the appearance can directly stimulate the impression of consumers, if the If there is a problem with the hinge that affects the appearance, then the product will not have a good market prospect, or even die befo...
