A rotary fixing structure comprises an outer end cover and an inner end cover. The outer end cover is integrally formed, made of plastic materials, and provided with an opening. A hung-in boss is arranged on the position, close to the opening, of the inner wall of the outer end cover. The side face, close to the opening, of the hung-in boss is a guide surface, and the guide surface extends in the circumferential direction of the outer end cover. The hung-in boss is provided with a notch and a sliding chute communicated with the notch, the sliding chute extends in the circumferential direction of the outer end cover, and clamping grooves are formed in the side walls of the sliding chute. The inner end cover is integrally formed and made of plastic materials. A hung-out boss and a sliding boss are arranged on the outer side wall of the inner end cover. The hung-out boss is arranged in the middle where the sliding boss is far away from the inner end cover relatively. A space exists between the hung-out boss and the sliding boss in the axial direction of the inner end cover. The side face, close to the sliding boss, of the hung-out boss is a matching surface, and the matching surface extends in the circumferential direction of the inner end cover. The sliding boss is provided with clamping parts which are clamped in the clamping grooves. The rotary fixing structure is convenient to demount and firm in fixation.
Description
[0001] 【Technical field】 [0002] The invention relates to a fixed structure, in particular to a rotation fixed structure. [0003] 【Background technique】 [0004] At present, most of the plastic parts on the market are fixed by threads or hooks. For example, the two connectors on the lamp are detachably fixed and connected by threads or hooks. The two connectors are cylindrical structures with different diameters, one of which is The connecting piece can be partially accommodated in another connecting piece. [0005] However, the efficiency of screw fixing is low, and tools are required for disassembly; in addition, it is difficult to disassemble and easy to break because it is fixed by hooks. [0006] 【Content of invention】 [0007] In view of the above situation, it is necessary to provide a rotation fixing structure that is easy to disassemble and securely fixed. [0008] A rotationally fixed structure comprising: [0009] The outer end cover is integrally formed of pla...
