Detailed Description

Reference is made to the accompanying drawings. The utility model provides a rotary buckle structure applied to a portable electronic terminal, which comprises a shaft 3, a first part 1, a second part 2, an elastic element 4 and a limiting block 5, wherein the first end of the shaft 3 is provided with a flat shaft section 30, and the elastic element 4, the limiting block 5, the first part 1 and the second part 2 are sleeved on the shaft 3. For application to portable electronic terminals, the outer diameter of the shaft is only 0.8mm or more. The shaft 3 and the second member 2 are respectively provided with a product connecting portion to be capable of being connected with two members (such as one of the left side housing and the right side housing and the middle fixing frame) which need to be rotatably connected, for example, the second member 2 is provided with a connecting handle 20, and the shaft 3 is provided with a connecting handle at the second end thereof (only a part of the shaft 3 is shown in the figure, a part close to the second end of the shaft 3 is not shown, and the first end and the second end of the shaft 3 are two ends of the shaft 3 respectively).

The central hole of the first member 1 matches the cross-sectional shape of the flat shaft section 30 and just fits into the flat shaft section 30, so that the first member 1 is in sliding fit with the flat shaft section 30 and only rotates synchronously with the shaft 3. The second component 2 is in clearance fit with the shaft 3, and a central hole of the second component 2 is a round hole which is matched with the outer diameter of the shaft of the flat shaft section 30 and can be sleeved on the shaft and rotate relative to the shaft 3. The limiting block 5 axially limits the first part 1 and the second part 2 at the end part of the first end of the shaft 3, the elastic element 4 tightly props the first part 1 and the second part 2 in the direction from the second end to the first end, the first part 1 and the second part 2 are in friction fit to provide rotating hand feeling or stop rotating at any time to achieve a positioning function at any time, and the elastic element 4 can be a ring spring or a disc spring shown in the figure. In practice, there may be a plurality of first members 1 and second members 2 arranged alternately.

The first end of axle 3 corresponds stopper 5 sets up neck groove 31, the hole 50 of stopper 5 is set up to the slotted hole, the both ends 51 of slotted hole matches with the biggest external diameter of flat axle section 30, the middle part both sides pore wall of slotted hole sets up the recess 52 that matches with neck groove tank bottom 32 diameter, makes stopper 5 can be blocked in neck groove 31 and can rotate, stopper 5 with set up angle limit structure between the first end tip of axle 3. During installation, firstly, the long round hole of the limiting block 5 is made to be consistent with the flat position direction of the first end, the limiting block 5 is sleeved into the flat shaft section 30 and compresses the elastic element 4, when the limiting block 5 reaches the neck groove 31, the limiting block 5 can rotate due to the fact that the groove 52 is matched with the diameter of the groove bottom 32 of the neck groove 31, when the limiting block 5 rotates to a locking angle, the limiting block 5 is loosened, under the propping of the elastic element 4, the limiting block 5 is locked by the angle limiting structure without being welded and fixed, the limiting block 5 can be guaranteed not to rotate relative to the shaft 3 any more, and the angle limiting structure is detachable and can be detached and reassembled if needed. When the device is implemented, the limiting block 5 can be a sheet with a thicker thickness.

The detachable angle limiting structure can adopt a groove wall part 33 of the shaft 3 corresponding to the neck groove 31 and a limiting groove 53 facing the first end of the limiting block 5 and matched with the groove wall part 33 in a rotation prevention manner.

The bottom of the two ends of the long round hole of the limiting block is also provided with 1 or a plurality of small grooves 54, so that the assembly rotation resistance caused by process burrs can be avoided, and the convenience of assembly of a small-diameter structure is improved.
