The first positioning portion 102 and the step portion 101 may have a distance, and the length of the distance does not exceed the thickness of the first assembly 20, so as to avoid the first assembly 20 from being displaced after being placed on the step portion 101.

In some embodiments, the first positioning portion 102 is a limiting protrusion, and the second positioning portion 201 is a limiting notch; in different examples, the first positioning portion 102 may also be a limiting notch, and the second positioning portion 201 is a limiting protrusion. In contrast, when the lens barrel 10 is thin, it is difficult to provide a position for providing the limiting notch, and the first positioning portion 102 is used as the limiting protrusion, which can better adapt to different lens barrels 10, so that the limiting arrangement has better adaptability.

In some embodiments, the second positioning portion 201 is a positioning plane, in this embodiment, mainly aiming at the case that the outer periphery side of the first assembly 20 is provided with an arc edge or a circle, the positioning plane is arranged along a chord on the outer periphery side, and any two points on the outer periphery side of the first assembly 20 are processed, so that under the condition that the use condition of the second positioning portion 201 is not affected, two points can be selected at the edge of the second positioning portion 201 to be cut; compared with other shapes, the positioning plane is easier to machine, and the machining precision requirement is lower.

In some of the embodiments, the stepped portion 101 is annularly disposed along the inner surface of the lens barrel 10. The annular step 101 is used for placing the first assembly 20, and can support the first assembly 20 at any position, thereby improving the assembly performance of the lens barrel 10 and the first assembly 20. In different examples, the step part 101 may also be provided singly, and it is sufficient that the first assembly part 20 can be placed and the first assembly part 20 is limited in the axial direction of the lens barrel 10; the step 101 may be provided at a plurality of intervals.

In some embodiments, when the first assembly 20 and the lens barrel 10 are assembled, an end surface of the lens barrel 10 protrudes out of an edge of the first assembly 20, and the edge of the first assembly 20 and an inner circumferential surface of the lens barrel 10 enclose to form a first glue groove. The end face of the lens barrel 10 protrudes out of the edge of the first assembly part 20 to form a first glue groove, so that glue can be applied at a later stage conveniently, and the lens barrel 10 and the first assembly part 20 can be fixed.

In some embodiments, the lens barrel 10 is bonded to the first assembly part 20, after the first assembly part 20 is assembled, the first assembly part is placed on the step part 101, glue is applied between the step part 101 and the first assembly part 20, and after the first assembly part is fixed at the position, glue is applied through the first glue groove, so that the first assembly part 20 and the lens barrel 10 are fixed in all directions.

In some embodiments, as shown in fig. 1, 3 and 4, the lens barrel further includes a second assembly 30, a second glue groove 103 is annularly formed on one end surface of the lens barrel 10, glue is filled in the second glue groove 103, and the second assembly 30 is connected with the end surface of the lens barrel 10, where the second glue groove 103 is formed, through a connection surface thereof. The second fitting 30 is fit-connected to one end surface of the lens barrel 10. During the assembling process, firstly, glue is injected into the second glue groove 103, then the connection surface of the second assembling part 30 is placed on the end surface of the lens barrel 10, and the connection surface of the second assembling part 30 is contacted with the glue in the second glue groove 103, so that the lens barrel 10 is fixed by gluing.

In some embodiments, as shown in fig. 5, a third positioning portion 301 is disposed on the connection surface of the second assembly 30, and the third positioning portion 301 is embedded into the second glue groove 103 in a connection state of the lens barrel 10 and the second assembly 30. This arrangement enables the second assembly member 30 to be assembled and positioned when the second assembly member 30 is connected at the end face of the lens barrel 10; meanwhile, the contact between the surfaces of the lens barrel 10 and the second assembly part 30 can be avoided, the use of glue can be reduced, and the probability of glue overflow is reduced; the second assembly 30 can be made to have better connectivity with the lens barrel 10.

In the process of assembling the second assembling member 30 with the lens barrel 10, the amount of glue injected into the second glue groove 103 cannot be accurately set, and in order to ensure the connection performance, an excessive amount of glue is usually injected into the second glue groove 103. During the assembly process, the excessive glue may overflow, and the glue overflow notch 302 enables the overflowing glue to flow to the outside of the lens barrel 10 along the glue overflow notch 302, so as to effectively avoid the condition that the overflowing glue flows to the inside of the lens barrel 10 and pollutes other assembly parts inside the lens barrel 10.

The overflow glue gaps 302 are arranged at intervals, so that the overflow glue gaps 302 have a better drainage effect, and glue can flow to the outer side of the lens barrel 10 through the adjacent overflow glue gaps 302. In different examples, the glue overflow notch 302 may also adopt a through groove structure arranged in a ring shape.
