In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The problem of torque force adaption commonly exists between a lens and a lens seat in an existing security monitor, a mobile phone camera, a notebook computer camera or a tablet computer. For example, no matter the screw thread is arranged in the lens mount, the lens is directly screwed into the lens mount and is in threaded connection with the lens mount; still directly with camera lens and the interference fit of lens mount inside wall, all have and be connected the problem of tension or becoming flexible between camera lens and the lens mount, cause the influence to production efficiency.

Based on the above problems, the inventor thinks that the torque force adaptation between the lens and the lens holder is formed, and the key point is to form the proper effect of the connection between the lens and the lens holder being not tight or loose. The joint of the lens seat and the lens is provided with certain elasticity, so that on one hand, the assembly and disassembly of the lens seat and the lens are convenient, and the problem of over-tight connection of the lens and the lens seat is solved; on the other hand, when the lens deviates due to the action of external force, the lens seat or the joint of the lens has certain elasticity, and the lens can also reset due to the action of the elasticity, so that the problem of lens focusing dislocation is avoided, and the problem of connection looseness between the lens and the lens seat is solved.

Under the guidance of the above-mentioned thinking, the inventor conceived to provide a first tubular portion projecting from the base, and a second tubular portion provided inside the first tubular portion, the first tubular portion being connected to the second tubular portion, with a space being formed between the first tubular portion and the second tubular portion. Like this, when the camera lens stretches into second tubulose portion and is connected with second tubulose portion inside wall, because the structural setting that forms the space between first tubulose portion and the second tubulose portion for the second tubulose portion possesses certain elasticity, consequently, can solve and be connected the problem of tension or not hard up between camera lens and the lens mount.

Further, the second tubular part and the lens can be connected through threads or interference fit. And by providing one or more grooves in the second tubular portion, the resilient effect of the second tubular portion can be further enhanced.

The following examples are based on the above considerations.

Referring to fig. 1 to 2, the present invention provides a self-adaptive lens holder 100, wherein the self-adaptive lens holder 100 includes a base 10 and a connecting portion 20. The connecting portion 20 protrudes from the base 10, and encloses with the base 10 to form an installation cavity 30, and the installation cavity 30 is used for connecting the lens body 200.

The connecting part 20 comprises a first tubular part 21 and a second tubular part 22 arranged on the inner side of the first tubular part 21, and a deformation groove 23 communicated with the installation cavity is formed between the first tubular part 21 and the second tubular part 22.

The second tubular portion 22 and the base 10 enclose the installation cavity 30, or the first tubular portion 21, the second tubular portion 22 and the base 10 enclose the installation cavity 30.

Referring to fig. 2, a deformation groove 23 is formed between the first tubular portion 21 and the second tubular portion 22, and the first tubular portion 21, the second tubular portion 22 and the base 10 enclose the installation cavity 30, so that the second tubular portion 22 has a certain elasticity. On one hand, the second tubular part 22 is convenient to assemble and disassemble with the lens, and the problem of over-tightness is solved; on the other hand, when the lens deviates due to the action of external force, the lens can also reset due to the elastic action of the second tubular part 22, so that the problem of lens focusing dislocation can not be caused, the problem of over looseness is solved, the self-matching lens mount is matched with the torsion of the lens, and the production efficiency and the product quality are improved.

Specifically, the end side of the first tubular portion 21 away from the base 10 is connected to the end side of the second tubular portion 22 away from the base 10, so that the opening of the deformation groove 23 is disposed toward the base 10. that is, the second tubular portion 22, the deformation groove 23 and the first tubular portion 21 form a structure similar to the shape of Greek letter η, so that the side of the second tubular portion 22 close to the base 10 has a certain elasticity.

Note that the end side of the first tubular portion 21 or the second tubular portion 22 refers to an end portion of the first tubular portion 21 or the second tubular portion 22 in the axial direction.

In addition, the structure of the second tubular part 22, the deformation groove 23 and the first tubular part 21, which is formed in a shape similar to greek η, is only illustrated in the accompanying drawings and should not be construed as a limitation to the present application, because in practice, as the size of the lens fitted to the self-adaptive lens holder 100 increases, the height of the second tubular part 22 increases, and thus, the second tubular part 22, the deformation groove 23 and the first tubular part 21 form a structure similar to an inverted U-shape of english letters, the key point of the present application is that the deformation groove 23 formed between the first tubular part 21 and the second tubular part 22 makes the second tubular part 22 elastic to a certain extent, thereby achieving the torsional force fit with the lens body 200.

In addition, two deformation slots 23 with opposite openings can be formed between the first tubular part 21 and the second tubular part 22. Specifically, the opening of one of the deformation slots 23 is disposed toward the base 10, and the opening of the other deformation slot 23 is disposed away from the base 10. The first tubular portion 21, the two deformation grooves 23 and the second tubular portion 22 together form a shape approximating the english letter H. At this time, the second tubular portion 22 also has a certain elasticity, which can achieve the above-mentioned effect of adapting to the lens torsion, thereby improving the production efficiency and the product quality.

Referring to fig. 4, in order to further enhance the elastic effect of the second tubular portion 22, a plurality of grooves 223 are disposed on the sidewall of the second tubular portion 22 adjacent to the opening of the deformation groove 23, and the plurality of grooves 223 are disposed in communication with the deformation groove 23 and spaced apart from each other.

Referring to fig. 4 and 6, in order to make the joint of the lens body 200 and the second tubular portion 22 uniformly applied with elastic force, further, the plurality of grooves 223 are disposed along the circumference of the second tubular portion 22.

Thereby realizing the installation and connection of the lens body 200 and the self-adaptive lens mount 100.

It should be noted that the number of the locking convex rings 222 is not limited to one, and in order to enhance the effect of the second tubular portion 22 in stabilizing the lens body 200, a plurality of the locking convex rings 222 are arranged along the axial direction of the second tubular portion 2, for example, 2, 3, etc.

In order to make the connection of the lens body 200 to the second tubular portion 22 more stable, the detent convex ring 222 is disposed close to the base 10. The depth of the lens body 200 extending into the second tubular portion 22 is increased, so as to further enhance the effect of stable connection.

When the lens body 200 is in interference fit with the second tubular portion 22, the cross section of the second tubular portion 22 may be circular, square, rectangular, regular pentagon, triangle, or irregular shape with irregular shape, so long as the interference fit between the second tubular portion 22 and the lens body 200 can be achieved. Correspondingly, the locking convex ring 222 is also provided with a circular, square, rectangular, regular pentagon, triangle or irregular shape corresponding to the cross section of the second tubular part 22.
