[0028] The realization, functional features and advantages of the present utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 11 , the present utility model provides a magnifying glass body spiral telescopic mechanism. The preferred embodiment of the magnifying glass body spiral telescopic mechanism of the present utility model includes an inner lining sleeve 1, an outer shell 2, a lower cover 3, and a camera assembly 4. The camera assembly 4 is fixedly arranged in the lower cover 3. The outer shell 2 is rotatably sleeved outside the lower cover 3. The inner lining sleeve 1 is telescopically arranged in the lower cover 3 and is located above the camera assembly 4. When the outer shell 2 is rotated, the inner lining sleeve 1 moves telescopically relative to the lower cover 3.

[0031] Specifically, in this embodiment, two double-threaded guide grooves 5 with the same direction are oppositely arranged on the inner wall of the outer shell 2. Z-shaped guide grooves 6 are arranged on both sides of the lower cover 3. Limiting shafts 7 are arranged on both sides of the inner lining sleeve 1. The limiting shafts 7 pass through the Z-shaped guide grooves 6 and then extend into the double-threaded guide grooves 5.

[0032] Such as Figure 2As shown, during use, when the outer shell 2 is rotated clockwise, the double spiral guide groove on the inner wall of the outer shell 2 drives the inner lining sleeve 1 to rotate and extend. At this time, when the outer shell 2 is continuously rotated, the limit shafts 7 on both sides of the inner lining sleeve 1 enter the guide groove at the top of the Z-shaped guide groove 6, and thus are limited. Conversely, when the outer shell 2 is rotated counterclockwise, the limit shafts 7 on both sides of the inner lining sleeve 1 are first released from the restriction of the guide groove at the top of the Z-shaped guide groove 6, and then retracted under the drive of the double spiral guide groove on the inner wall of the outer shell 2. When the outer shell 2 is continuously rotated counterclockwise, the limit shafts 7 on both sides of the inner lining sleeve 1 enter the guide groove at the bottom of the Z-shaped guide groove 6, and thus are limited.

[0033] Thus, in this embodiment, by rotating the outer shell 2 to drive the telescopic movement of the inner lining sleeve 1, the purpose of adjusting the focal length of the camera can be achieved, so as to meet the photographing requirements of the product.

[0034] Further, in this embodiment, limit shaft inlet grooves communicating with the Z-shaped guide groove 6 are provided at the tops of both sides of the inner lining sleeve 1. By providing the limit shaft inlet grooves at the tops of both sides of the inner lining sleeve 1 in this embodiment, it is convenient to assemble the inner lining sleeve 1 and the lower cover 3.

[0035] A limit shaft guide groove 10 is vertically provided at the bottom of the double spiral guide groove. By vertically providing the limit shaft guide groove 10 at the bottom of the double spiral guide groove in this embodiment, it is convenient to assemble the outer shell 2.

[0036] In this embodiment, the assembly process of the inner lining sleeve 1, the lower cover 3 and the outer shell 2 is as follows:

[0037] First, the limit shafts 7 on both sides of the inner lining sleeve 1 are inserted from the limit shaft inlet grooves to complete the assembly of the inner lining sleeve 1 and the lower cover 3. Then, the limit shaft guide groove 10 vertically provided on the inner wall of the outer shell 2 is aligned with the limit shaft 7, and the outer shell 2 is sleeved on the lower cover 3 from top to bottom.

[0038] It should be noted that in order to ensure the assembly stability of the outer shell 2, after the outer shell 2 is sleeved on the lower cover 3, a limiting member (not shown in the figure) is sleeved from top to bottom, and the limiting member is tightened with the bottom of the lower cover 3 by screws. At this time, the outer shell 2 can only rotate around the lower cover 3 and cannot move up and down.

[0039] Further, in this embodiment, a ring-shaped boss 8 is provided below the Z-shaped guide groove 6 in the lower cover 3. In this embodiment, the ring-shaped boss 8 can play a role in supporting and limiting the inner lining sleeve 1 and the camera assembly 4.

[0040] Further, in this embodiment, the magnifying glass body screw telescopic mechanism further includes a rear cover 9, and the rear cover 9 is clamped at the bottom of the lower cover 3.

[0041] Further, in this embodiment, the inner lining sleeve 1, the outer shell 2, and the lower cover 3 are all circular rings.

[0042] The beneficial effects of the magnifying glass body screw telescopic mechanism of the present utility model are as follows:

[0043] The present utility model has the same technical solution as above, including: an inner lining sleeve, an outer shell, a lower cover, and a camera assembly. The camera assembly is fixedly arranged inside the lower cover. The outer shell is rotatably sleeved outside the lower cover. The inner lining sleeve is telescopically arranged inside the lower cover and is located above the camera assembly. When the outer shell is rotated, the inner lining sleeve moves telescopically relative to the lower cover. By rotating the outer shell to drive the inner lining sleeve to move telescopically, the purpose of adjusting the focal length of the camera is achieved, saving space, making the product more compact and flexible, more convenient to use and carry, and enhancing the competitiveness of the product.

[0044] To achieve the above object, the present utility model further provides a handheld photographing and imaging device, which includes the magnifying glass body screw telescopic mechanism as described above. The structure and working principle of the magnifying glass body screw telescopic mechanism have been elaborated in detail above and will not be repeated here.

[0045] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
