Problems solved by technology
However, in the process of screwing the lens barrel into the lens holder, the external thread on the outer wall of the lens barrel is often damaged due to the excessive rotation torque.
Because the external thread is directly arranged on the outer wall of the lens barrel, once the external thread is damaged, the entire lens barrel will be scrapped, and lenses with high cost are usually arranged in the lens barrel, so scrapping the lens barrel will cause lens mold. Group production costs increase

Embodiment Construction
[0010] Please also refer to Figure 1 to Figure 3 , The lens module 1 provided by the first embodiment of the present invention includes a lens barrel 10 , a lens 12 , a connector 14 and a lens base 16 . The lens 12 is arranged in the lens barrel 10 . The lens barrel 10 is screwed to the lens base 16 through the connecting piece 14 .
[0011] The lens barrel 10 includes a top cover 100 and a receiving portion 102 . The receiving portion 102 is a hollow cylinder including an outer wall 102a and an inner wall 102b. The top cover 100 is a circular thin plate with a light-transmitting hole 100a defined in the center thereof. The top cover 100 is disposed at one end of the receiving portion 102 and forms a receiving space 103 together with the receiving portion 102 . The central axis of symmetry of the top cover 100 coincides with the central axis of symmetry of the receiving portion 102 . The lens 12 is disposed in the accommodating space 103 . The optical axis of the lens 1...

The invention relates to a lens module which comprises a lens barrel, a connecting piece and a lens base. The lens barrel comprises a cylindrical holding part, and at least one positioning lug is vertically arranged on the lateral wall of the holding part along the direction parallel to a central axis of the lens barrel in an extending manner. The lens base comprises a spiral connecting part which is provided with a second thread. A positioning groove corresponding to the positioning lug and a first thread corresponding to the second thread on the lens base are formed on the connecting piece.The connecting piece and the lens barrel are mutually matched through the positioning lug and the corresponding positioning groove. The first thread is engaged with the second thread.
Description
technical field [0001] The invention relates to a lens module. Background technique [0002] The existing lens module usually includes a lens barrel, a lens installed in the lens barrel, and a hollow lens seat for accommodating the lens barrel. Internal threads are provided on the inner side wall of the mirror base, and external threads corresponding to the internal threads are provided on the outer wall of the lens barrel. The lens barrel is screwed into the lens holder through mutual cooperation between the internal and external threads. However, during the process of screwing the lens barrel into the lens holder, the external thread on the outer wall of the lens barrel is often damaged due to excessive rotational torque. Because the external thread is directly arranged on the outer wall of the lens barrel, once the external thread is damaged, the entire lens barrel will be scrapped, and lenses with high cost are usually arranged in the lens barrel, so scrapping the lens...
