Abstract

The invention relates to a clamping structure which is suitable for clamping a first fixed block on a second fixed block, wherein, two mounting parts are arranged on the first fixed block; at least one clamping hole is arranged on the second fixed block; the clamping structure comprises a rotary shaft which is pivotally arranged on the two mounting parts; an actuating part capable of freely rotating around the rotary shaft is pivotally arranged on the rotary shaft; at least one clamping part and a groove are arranged on the actuating part; an elastic component is sleeved outside the rotary shaft and between the two mounting parts; a stretching part capable of being clamped inside the groove is arranged on the elastic component; during the process of clamping, external force is needed for pressing the first fixed block provided with the clamping structure towards the second fixed block, and the clamping part is made to be screwed into the clamping hole in the preset direction; the external force is removed and the clamping part is made to rotate in the direction opposite to the preset direction and then be clamped outside the second fixed block, thereby convenience of assembly and disassembly is improved.

Description

【Technical field】 [0001] The invention relates to a snap-fit ​​mechanism, in particular to a snap-fit ​​mechanism that is convenient for assembly and disassembly. 【Background technique】 [0002] The casing of existing electronic devices (such as mobile phones or personal digital assistants, etc.) is usually composed of two independent parts, that is, the casing includes a front cover and a rear cover, wherein the front cover is provided with several screws. The rear cover is correspondingly provided with several screw holes, which can be locked in these studs after passing through these screw holes by several screws, so that the front cover and the rear cover are assembled into a closed shell. [0003] However, when the shell is assembled, the screws need to be locked one by one; and when the shell is disassembled, the screws need to be withdrawn one by one, which brings troubles to the assembly or disassembly of the shell. 【Content of invention】 [0004] The main purpose...
