1-Large spring mechanical structure of mobile phone

The utility model provides a large spring mechanical structure of mobile phone. Two bearing guide rail isarranged in parallel, slot arranged at two ends of the supporting guide rail carriage; screw through screw seat is fixed on the carriage, at both ends of the screw seat is arranged in the fixed, and one end is connected with the reducer; the lifting cylinder slideway type transverse arm and a carriage with two fingers inside the slideway type; cross linked arms and fingers slide, telescopic cylinder, adjusting hand wheel. The utility model has the advantages of reasonable structure, convenient use, fast, effectively improve the working efficiency and the effect of magnetic powder inspection, and also can be suitable for large spring and other production,processing.

2-Constant force spring mechanism of sliding cover sliding module of mobile phone

Constant force spring mechanism of the utility model discloses a sliding module of mobile phone sliding coverdata abstract, includes a support member, the support member in parallel with a relative sliding the first push rod and the second rod, one end of the first push rod and the second rod are respectively connected with the coil, coil spring is fixed on the supporting member, the other end of the push rod the support member which can rotate and slide out of the other end of the connection, putting out a second support member rotatably connected with the body; the spring of the utility model makes the stress of each section are almost constant,the sliding cover the use of smooth, smooth, dead without normal spring release impact and the critical point.
