The invention discloses a telescopic lens and a mobile device. The telescopic lens comprises a first shell part, a second shell part and a sealing structure, the first shell part is provided with a mounting channel, and the mounting channel penetrates through the first shell part; the second shell part is movably mounted in the mounting channel in the depth direction of the mounting channel and can extend out of the mounting channel from one end of the mounting channel, and a gap is formed between the periphery of the second shell part and the side wall of the mounting channel; the sealing structure comprises a fixing section and a sealing section extending from the fixing section to the gap, the fixing section is arranged on one of the first shell part and the second shell part, the sealing section is provided with a plurality of abutting protruding parts in a protruding mode, and the abutting protruding parts are arranged at intervals in the depth direction of the mounting channel and extend into the gap, so as to abut against the other one of the first shell part and second shell part, so that the first shell part and second shell part are in sealing fit. The sealing effect of the telescopic lens is good, the situation of flanging is avoided, and the sealing performance is improved.
Description
technical field [0001] The invention relates to the field of lens technology, in particular to a telescopic lens and a mobile device. Background technique [0002] With the improvement of people's quality of life, many mobile devices, including mobile phones, tablet computers, and notebook computers, are equipped with telescopic lenses, such as telescopic lenses in mobile phones. In the prior art, gap fit is generally used between the telescopic parts of the telescopic lens. A sealing ring is arranged in the gap of the telescopic lens, and when the telescopic lens stretches and moves, it is easy to cause the sealing ring to flang, and the sealing effect becomes poor. Contents of the invention [0003] The main purpose of the present invention is to provide a telescopic lens, aiming at improving the technical problem in the prior art that the sealing ring is easily flanged and the sealing effect is deteriorated when the telescopic lens is telescopically moved. [0004] In ...
