[0026] With reference to the drawings, the present embodiment takes an inward folding flexible screen mobile phone as an example, which comprises a left side shell 101, a right side shell 102 and a middle shell 103, a flexible screen is laid on the inner side of the mobile phone, and a hinge is connected with the middle shell 103. When the mobile phone is folded outward, the flexible screen is unfolded and opened, and when the mobile phone is folded inward, the flexible screen is folded and closed. The fixing structure of the present application can be a certain fixed component or structure in the hinge or a certain other fixing structure (such as a cover plate, a fixed support, etc.) on the middle shell of the mobile phone, etc. The fixing structure 200 in the present embodiment takes a middle support as an example, which serves as a middle support plate of the flexible screen and also sets a fixing structure in the hinge.

[0027] The present application provides a fixing structure of a folding mobile terminal and a connecting structure of a middle shell, which comprises a connecting piece 1 and a locking piece 2.

[0028] The connecting piece 1 comprises a connecting column 13, a first clamping block 11 radially protruding from one end of the connecting column 13, and an operable pressing block 12 at the other end of the connecting column 13, so as to be able to rotate and operate the connecting piece 1. The fixing structure 200 is provided with a first connecting hole 201, the middle shell 103 is provided with a second connecting hole 3 at the connecting position, the second connecting hole 3 is provided with a second clamping block 4 capable of clamping and cooperating with the first clamping block 11, the second connecting hole 3 is provided with a space 31 for the rotation of the first clamping block 11 below the second clamping block 4, the first connecting hole 11 can be aligned with the second connecting hole 4, the connecting column 13 and the first clamping block 11 of the connecting piece 1 can be inserted into the first connecting hole 11, the first clamping block 11 can be inserted into the space for the rotation of the first clamping block 11 to clamp and cooperate with or release the clamping and cooperation with the second clamping block 4, and the pressing block 12 is located outside the aperture of the first connecting hole 201.

[0029] The lock 2 comprises a lock leg 21, the pressing block 12 and the first and second clamping blocks 11, 4 occupy part of the circumferential angle, and can be inserted into the lock leg 21 in the remaining part of the circumferential direction when the first and second clamping blocks 11, 4 are clamped and matched, and can prevent the first clamping block 11 from rotating out of the range of the second clamping block 4 (release the clamping and matching between the first and second clamping blocks 11, 4) after being inserted into the lock leg 21. The lock leg 21 is provided with a reversibly deformed protrusion 22, and preferably the second connecting hole 3 is provided with a groove 203 matched with the protrusion 22, so that after the lock leg 21 is inserted downward, the clamping and matching with the protrusion 22 is formed, the lock leg 21 is locked to prevent it from being pulled out, so that the first clamping block 11 can be rotated. When the parts in the middle shell 103 need to be replaced, if the lock leg 21 is subjected to sufficient upward external force (such as prying or pulling the lock), the reversibly deformed protrusion 22 can be pulled out of the groove 203, so that after the lock leg 21 is pulled out, the lock 2 can be rotated to dismount the fixed structure 200 from the middle shell 103.

[0030] The lock 2 is at least the protrusion 22 which is a flexible component, and preferably the lock 2 can be a rubber plug, which is a silica gel component. The connecting clamping piece 1 is a metal component.

[0031] Preferably, the first and second clamping blocks 11, 4 are both fan-shaped blocks, the second clamping block 4 is located on the hole wall of the second connecting hole 3, and the first clamping block 11 is located at the bottom end of the connecting column 13 and protrudes radially from the connecting column 13.

[0032] Preferably, as shown in the figure, the first and second clamping blocks 11, 4 and the pressing block 12 are both provided with two blocks, and the pressing block 12 is provided on the same side as the first clamping block 11, that is, for example, assuming that the two first clamping blocks 11 are provided at the 6 o'clock direction and the 12 o'clock direction relative to the circumferential direction of the connecting column 13, then the two pressing blocks 12 are provided at the 6 o'clock direction and the 12 o'clock direction relative to the circumferential direction of the connecting column 13. In this way, not only the strength of the clamping connection is strengthened, but also the rotating operation of the pressing block 12 is facilitated, and the structural reliability of the lock is also improved.

[0033] The lock 2 comprises two lock legs 21 provided opposite to each other, and a top structure 23 connected between the two lock legs 21, the top structure 23 covers the pressing block 12, and the top structure 23 matches with the first connecting hole 201 to fill the top 202 of the first connecting hole 201.
