Description

Technical Field

[0001] The utility model relates to the technical field of lens barrels, in particular to an optical lens barrel housing. Background Art

[0002] With the rapid development of multimedia technology, digital cameras, video cameras, and mobile phones with cameras are increasingly favored by consumers. While people put forward higher requirements for the image quality of objects photographed by digital cameras, video cameras, and mobile phone cameras, the demand for products such as digital cameras, video cameras, and mobile phones with cameras is also increasing. In photographic devices such as digital cameras, video cameras, and mobile phone cameras, the lens module is an indispensable component.

[0003] The lens module usually includes a lens barrel, a lens holder, an optical imaging element, and an image sensor. The optical imaging element is housed in the lens barrel. A lens barrel is provided in the patent with the application number CN202020295704.7, which can better resist external impacts, but this device has certain defects. For example, due to the existence of the buffer strip, the lens will be eccentric, and at the same time, the lens inside the lens barrel is not easy to replace, and it is not easy to take out after being damaged. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide an optical lens barrel housing. This device uses a connecting pipe with anti-seismic and anti-eccentric functions to solve the problem of lens eccentricity after collision, and at the same time uses multiple lens disassembly connections to solve the problems that the lens inside the lens barrel is not easy to replace and take out.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An optical lens barrel housing, comprising: composed of a plurality of detachable lenses; the lens includes a connecting pipe with anti-seismic and anti-eccentric functions, a spiral pipe installed on the connecting pipe, and a lens installed inside the spiral pipe.

[0007] Preferably, the connecting pipe includes an internal thread ring, an inner ring for installing the internal thread ring, a limiter provided on the inner ring, an internal gear ring meshed with the limiter, a rotating ring for installing the internal gear ring, a shock absorber provided on the rotating ring, and an outer ring connected to the shock absorber.

[0008] Preferably, the limiter includes a fixing block installed on the inner ring, a limiting shaft threadedly connected to the fixing block, and a gear threadedly connected to the limiting shaft; the limiter is meshed with the internal gear ring through the gear.

[0009] Preferably, the shock absorber includes a shock-absorbing shaft fixed on the rotating ring, a spring mounted on the shock-absorbing shaft, and a shock-absorbing tube connected to the spring; the shock absorber is installed on the outer ring through the shock-absorbing tube.

[0010] Preferably, at least two of the limiters and shock absorbers are provided and are arranged in an array along the central axis of the connecting pipe.

[0011] Preferably, the spiral tube includes a limit groove, a tube body for opening the limit groove, and an external thread ring mounted on the tube body.

[0012] Preferably, the thread sizes of the external thread ring and the internal thread ring are the same.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] The present utility model uses multiple lenses to be detachably connected, solving the problem that the lenses inside the lens barrel are not easy to replace and take out. At the same time, the connecting pipe has two major components, namely a limiter and a shock absorber. The shock absorber is connected to the outer ring through the shock-absorbing tube and is connected to the rotating ring through the shock-absorbing shaft. When the lens collides, the outer ring eliminates the shock force through the spring on the shock absorber, thus playing a protective role for the lens and having a shock-proof effect. At the same time, when two or more lenses are connected, after the upper lens is inserted into the connecting pipe of the lower lens through the spiral tube, rotate the rotating ring. Under the action of the internal gear ring on the gear, the limit shaft in the limiter is pushed out and buckles in the limit groove of the spiral tube to limit the spiral tube and prevent the spiral tube from being eccentric.

[0025] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the features in the following embodiments can be combined with each other.

[0026] An optical lens barrel housing includes: being composed of a plurality of detachable lenses 1; the lens 1 includes a connecting tube 10 having functions of shock prevention and eccentricity prevention, a spiral tube 20 installed on the connecting tube 10, and a lens 30 installed inside the spiral tube 20.

[0027] Such as Figure 1 AndFigure 2 As shown in the figure, the optical lens barrel is formed by connecting a plurality of lenses 1 through upper and lower threads. The lens 1 is composed of a connecting pipe 10, a spiral pipe 20, and a lens 30 installed inside the spiral pipe 20. The connecting pipe 10 and the spiral pipe 20 are connected in a detachable manner.

[0028] Furthermore, the connecting pipe 10 includes an internal thread ring 11, an inner ring 12 for installing the internal thread ring 11, a stopper 13 provided on the inner ring 12, an internal gear ring 14 meshed with the stopper 13, a rotating ring 15 for installing the internal gear ring 14, a shock absorber 16 provided on the rotating ring 15, and an outer ring 17 connected to the shock absorber 16.

[0029] Furthermore, the stopper 13 includes a fixing block 131 installed on the inner ring 12, a limiting shaft 132 threadedly connected to the fixing block 131, and a gear 133 threadedly connected to the limiting shaft 132; the stopper 13 is meshed with the gear ring 14 through the gear 133.

[0030] Furthermore, the shock absorber 16 includes a shock-absorbing shaft 161 fixed to the rotating ring 15, a spring 162 installed on the shock-absorbing shaft 161, and a shock-absorbing pipe 163 connected to the spring 162; the shock absorber 16 is installed on the outer ring 17 through the shock-absorbing pipe 163.

[0031] Furthermore, at least two stoppers 13 and shock absorbers 16 are provided, and they are arranged in an array along the central axis of the connecting pipe 10.

[0032] As Figure 4 shown, six stoppers 13 and six shock absorbers 16 are provided respectively.

[0033] Furthermore, the spiral pipe 20 includes a limiting groove 21, a pipe body 22 for opening the limiting groove 21, and an external thread ring 23 installed on the pipe body 22.

[0034] Furthermore, the thread dimensions of the external thread ring 23 and the internal thread ring 11 are the same.

[0035] As Figures 1 to 6 shown, the present utility model is composed of a plurality of detachable lenses 1. Each lens 1 is internally provided with a lens 30. If a certain lens 1 needs to be replaced with a different lens 3 or the lens 3 is damaged, only that lens 1 needs to be disassembled and replaced.

[0036] In order to achieve the functions of shock prevention and eccentricity prevention, the present utility model is provided with stoppers 13 and shock absorbers 16 inside the connecting pipe 10, and six of each are provided, which are arranged in an array along the central axis of the connecting pipe 10 (as Figure 4) The stopper 13 has a limiting function. The gears 133 in the six stoppers 13 are meshed with the internal tooth ring 14. By rotating the internal tooth ring 14, the six seismic resistance shafts 161 in the six stoppers 13 can be adjusted to move in and out synchronously. When the seismic resistance shafts 161 extend, they are simultaneously buckled in the limiting grooves 21 on the spiral tube 20, playing a role in limiting and rectifying the spiral tube 20 threadedly connected to the connecting pipe 10, preventing the lenses 30 installed in the spiral tube 20 from colliding and causing displacement; the stopper 13 is used in cooperation with the seismic damper 16. The seismic damper 16 has a shockproof effect. When the connecting pipe 10 collides, the generated shock force is transmitted from the outer ring 17 of the connecting pipe 10 to the seismic damper 16, and then the shock force is eliminated by the spring 162 in the seismic damper 16, thereby preventing the rotating ring 15 from vibrating and achieving a shockproof effect.
