Description

Technical Field

[0001] This invention relates to the field of mobile phone lens barrel technology, specifically to an optical lens barrel that is easy to install and disassemble. Background Technology

[0002] With the rapid development of modern information technology and the continuous improvement of people's living standards, mobile phones, as a daily communication tool, have become ubiquitous and are now widely used. Most mobile phones used today are smartphones. With the upgrading of mobile phones, photography, as an essential function of smartphones, has been increasingly improved and enhanced in terms of pixels and other aspects. Consequently, in order to obtain different shooting effects and meet some special shooting needs, external lenses for mobile phones have gradually entered the public eye. Based on the mobile phone itself, external lenses meet different shooting needs and achieve some effects that the mobile phone's own lens cannot achieve.

[0003] Existing external optical tubes are cumbersome to install and remove, often using precision screws for fixation, or even fixed to a bracket and impossible to disassemble. While this method offers high stability, it lacks practicality. Therefore, we propose an optical tube that is easy to install and remove. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to use tools to stably and conveniently disassemble and install external lens barrels.

[0005] To address the aforementioned technical problems, this application provides an optical lens barrel that is easy to install and disassemble, including a mounting bracket, of which two brackets are provided, and a mounting frame is provided above the mounting bracket. It also includes: two fixing components, both of which are disposed inside the mounting frame, used to fix an external lens to the mounting frame; and an adjustment component, disposed on one side of the mounting bracket, used to adjust the distance between the mounting brackets to fit the thickness of the mobile phone.

[0006] In some embodiments, the fixing assembly includes cylindrical tubes disposed on both sides of the mounting bracket, a pressing rod disposed inside the cylindrical tube, a connecting post disposed below the pressing rod, the lower end of the connecting post being arc-shaped, a partition plate disposed below the connecting post, a first elastic member disposed below the partition plate, and an offset member disposed below the connecting post.

[0007] In some embodiments, the offset member includes an offset plate disposed inside the cylindrical tube, the offset plate having a groove inside, one side of the groove having a rounded corner configured to match the shape of the lower end of the connecting column, and a spring-loaded member disposed on one side of the offset plate.

[0008] In some embodiments, the spring-loaded member includes an elastic sheet disposed on one side of the offset plate, a slot is provided on the side of the cylindrical tube near the elastic sheet, a locking rod is disposed below the first elastic member, and a second elastic member is sleeved on the outer side of the locking rod.

[0009] In some embodiments, the adjustment assembly includes a square plate disposed on one side of two fixed frames, the square plate having a first groove inside, the fixed frames being slidably disposed inside the first groove, a rotating shaft being disposed on one side of the square plate, a gear being sleeved on the side of the rotating shaft near the first groove, racks being disposed on both sides of the gear, a fixed frame being fixedly connected to one end of each of the two racks, and a limit member being disposed on one side of the rotating shaft.

[0010] In some embodiments, the limiting member includes a movable plate disposed on one side of the rotating shaft, a sliding plate disposed on one side of the movable plate, a second sliding groove opened on one side of the square plate, the sliding plate being slidably disposed in the second sliding groove, one end of the movable plate being semi-circular in shape and having the same radius as the rotating shaft, a first screw disposed on one side of the movable plate, and a first anti-slip knob disposed on one side of the first screw.

[0011] Both of the fixing plates have square holes inside, and the size of the square blocks is the same as the size of the rack.

[0012] A guide cylinder is provided above the mounting bracket, and a mark is provided above the guide cylinder.

[0013] The fixed frame has a third sliding groove on its upper part, and a slider is provided inside the third sliding groove. The upper end of the slider is fixedly connected to a mounting bracket, and a locking element is provided on one side of the slider.

[0014] The locking component includes a second screw located on one side of the slider, and a second anti-slip knob is provided on one side of the second screw.

[0015] This invention has at least the following beneficial effects:

[0016] Unlike existing technologies, this design utilizes the interplay of a pivot, gears, racks, and mounting brackets to adjust the distance between the brackets, thus accommodating more mobile phones and increasing product usability. The external lens barrel is then secured by the combination of a pressing rod, connecting post, and first elastic component. Finally, the external lens barrel can be unlocked by the combination of a pressing rod, connecting post, offset plate, and elastic sheet. This prevents situations where the external lens barrel cannot be disassembled due to a lack of tools, and the pressing method for securing and disassembling is quicker and more convenient.

[0031] The fixing component 3 includes cylindrical tubes 31 disposed on both sides of the mounting bracket 2. A pressing rod 32 is disposed inside the cylindrical tube 31. A connecting post 33 is disposed below the pressing rod 32. The lower end of the connecting post 33 is shaped as an arc. A partition plate 34 is disposed below the connecting post 33. A first elastic component 35 is disposed below the partition plate 34. An offset component 36 is disposed below the connecting post 33. When the connecting post 33 presses down again, the connecting post 33 presses down on the offset plate 361, so that the offset plate 361 is...

[0032] The offset member 36 includes an offset plate 361 disposed inside the cylindrical tube 31. The offset plate 361 has a groove 362 inside. One side of the groove 362 has a rounded corner that matches the shape of the lower end of the connecting post 33. A spring-loaded member 37 is disposed on one side of the offset plate 361. When the connecting post 33 presses down again, the connecting post 33 presses down on the offset plate 361, causing the offset plate 361 to move inside the cylindrical tube 31.

[0033] The spring-loaded component 37 includes an elastic piece 371 disposed on one side of the offset plate 361. A slot 372 is provided on the side of the cylindrical tube 31 near the elastic piece 371. A locking rod 373 is disposed below the first elastic component 35. A second elastic component 374 is sleeved on the outside of the locking rod 373. The movement of the offset plate 361 drives the elastic piece 371, thereby causing the elastic piece 371 to leave the slot 372.

[0034] The adjustment assembly 4 includes a square plate 41 disposed on one side of the two fixed frames 1. The square plate 41 has a first slide groove 42 disposed inside. The fixed frame 1 is slidably disposed inside the first slide groove 42. A rotating shaft 43 is disposed on one side of the square plate 41. A gear 44 is sleeved on the side of the rotating shaft 43 near the first slide groove 42. A rack 45 is disposed on both sides of the gear 44. One end of each rack 45 is fixedly connected to a fixed frame 1. A limit member 46 is disposed on one side of the rotating shaft 43.

[0035] The limiting component 46 includes a movable plate 461 disposed on one side of the rotating shaft 43, a sliding plate 462 disposed on one side of the movable plate 461, a second sliding groove 463 opened on one side of the square plate 41, the sliding plate 462 is slidably disposed in the second sliding groove 463, one end of the movable plate 461 is semi-circular in shape and the radius is the same as the radius of the rotating shaft 43, a first screw 464 is disposed on one side of the movable plate 461, and a first anti-slip knob 465 is disposed on one side of the first screw 464. When limiting is required, the lower end of the movable plate 461 presses against the rotating shaft 43 and locks the first screw 464.

[0036] Both fixing plates have square holes 5 inside. The size of the square block is the same as that of the rack 45. When the fixing brackets 1 are relatively close, the rack 45 passes through the square holes 5, extending the adjustable width.

[0037] A guide cylinder 6 is provided above the mounting bracket 2. A mark is provided above the guide cylinder 6. The guide cylinder 6 is used to facilitate the installation of the external lens barrel. The mark is provided to prevent the lens barrel from being installed in the wrong direction, thereby ensuring the accuracy of the focal length.

[0038] In summary, first, rotating the shaft 43 drives the gear 44 to rotate, which in turn drives the rack 45 to move, thus making the distance between the fixing brackets 1 suitable for the thickness of the mobile phone. Then, the external lens is moved into the mounting bracket 2 through the marking and guide cylinder 6. Then, pressing the pressing rod 32 drives the connecting column 33 to press down on the first elastic component 35, thereby causing the first elastic component 35 to press the locking rod 373, causing the locking rod 373 to move into the locking groove on the side with the external lens barrel. When unlocking is required, pressing the pressing rod 32 again drives the connecting column 33 to move downward, thereby causing the offset plate 361 to move to one side, so that after the elastic piece 371 leaves the slot 372, due to the compression state of the first elastic component 35 and the second elastic component 374, there is a rebound force, thereby causing the locking rod 373 to leave the locking groove. After removing the external lens barrel, the disassembly steps are completed.
