Description

Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a zoom lens structure. Background Technology

[0002] With the rapid development of beauty technology, laser beauty devices have become widely popular due to their efficient and precise skin treatment and cosmetic effects. However, existing laser beauty devices often suffer from problems such as complex operation, low adjustment precision, or poor structural stability when adjusting the size of the laser focus spot. These problems not only affect the cosmetic effect but may also cause unnecessary damage to the user's skin; therefore, we propose a zoom lens structure to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a zoom lens structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A zoom lens structure, comprising:

[0007] A rotating ring, which is rotatably sleeved on the outside of the spiral support;

[0008] A lens fixing component is disposed within the spiral bracket, and a plurality of sliding posts are inserted into the outer side of the lens fixing component, the sliding posts being movably inserted into the spiral groove;

[0009] A plano-convex lens, used to focus a parallel laser beam, is fixedly mounted inside a lens holder.

[0010] Preferably, the rotating ring has a straight groove inside, and the sliding column is slidably installed in the straight groove.

[0011] Preferably, the spiral grooves are configured in three groups, and the three groups of spiral grooves are distributed in a ring with equal spacing.

[0012] Preferably, the top end of the rotating ring is provided with an observation bracket, and the top end of the rotating ring is spirally connected with a locking ring, which is movably sleeved on the outside of the observation bracket.

[0013] Preferably, a scale indicator ring is fixedly installed on the outer side of the spiral bracket, and a focal length scale is provided on the outer side of the rotating ring.

[0014] Preferably, the outer side of the lens fixing member is provided with a threaded groove, and one end of the sliding column is integrally formed with a threaded rod, which is threadedly installed in the threaded groove.

[0015] Preferably, the outer side of the rotating ring is provided with multiple anti-slip grooves.

[0016] In this utility model, a zoom lens structure is described, in which a rotating ring is rotated and the lens fixing component is driven to rotate synchronously with the rotating ring through the cooperation of the straight groove and the sliding column, and the lens fixing component moves up and down while rotating through the cooperation of the spiral groove and the sliding column, thereby changing the distance between the plano-convex lens and the end face of the observation bracket, which can change the size of the laser spot that is finally focused.

[0017] In this utility model, the zoom lens structure described herein allows users to easily observe the focal length scale on the outside of the rotating ring through the scale indicator ring, thereby knowing what kind of light spot the current position of the plano-convex lens can focus into, so as to facilitate appropriate adjustments.

[0018] This utility model has a reasonable structural design. The combination of the rotating ring, spiral support and sliding column makes it easy to adjust the position of the plano-convex lens, thereby facilitating the adjustment of the size of the laser focusing spot. It is also simple to operate and easy to use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 A zoom lens structure, comprising:

[0027] The spiral support 7 has a spiral groove on its outer side;

[0028] Rotating ring 3 is rotatably sleeved on the outside of spiral bracket 7;

[0029] Lens fixing component 5 is set inside the spiral bracket 7, and several sliding posts 6 are inserted into the outer side of the lens fixing component 5. The sliding posts 6 are movably inserted into the spiral groove.

[0030] The plano-convex lens 4 is used to focus the parallel laser. The plano-convex lens 4 is fixedly installed inside the lens holder 5.

[0031] In this embodiment, the rotating ring 3 has a straight groove inside, and the sliding column 6 is slidably installed in the straight groove.

[0032] In this embodiment, the spiral grooves are set in three groups, and the three groups of spiral grooves are distributed in a ring with equal spacing. Through the three evenly distributed spiral grooves, the plano-convex lens 4 can be made flatter during the movement.

[0033] In this embodiment, an observation bracket 2 is provided at the top of the rotating ring 3, and a locking ring 1 is spirally connected to the top of the rotating ring 3. The locking ring 1 is movably sleeved on the outside of the observation bracket 2. The observation bracket 2 leaves a distance between itself and the plano-convex lens 4 at the working position, so that the operator can easily view the red sight.

[0034] In this embodiment, a scale indicator ring 8 is fixedly installed on the outer side of the spiral bracket 7, and a focal length scale is provided on the outer side of the rotating ring 3. The focal length scale is made of laser engraving, so that when adjusting the spot size, the user can clearly know which way to rotate to adjust to the desired level.

[0035] In this embodiment, a threaded groove is provided on the outer side of the lens fixing member 5, and a threaded rod is integrally formed on one end of the sliding column 6. The threaded rod is threadedly installed in the threaded groove, thereby realizing the fixing of the sliding column 6 and the lens fixing member 5.

[0036] In this embodiment, multiple anti-slip grooves are provided on the outer side of the rotating ring 3, thereby facilitating manual control of the rotation of the rotating ring 3.

[0037] In this embodiment, during use, rotating the rotating ring 3 and engaging the straight groove and sliding column 6 causes the lens fixing member 5 to rotate synchronously with the rotating ring 3. The engagement of the spiral groove and sliding column 6 causes the lens fixing member 5 to move up and down while rotating, thereby changing the distance between the plano-convex lens 4 and the end face of the observation bracket 2. This changes the size of the laser spot that is finally focused. The scale indicator ring 8 allows the user to easily observe the focal length scale on the outside of the rotating ring 3, thus knowing what kind of spot the current position of the plano-convex lens 4 can focus into, so as to facilitate appropriate adjustments.

[0038] The above provides a detailed description of the zoom lens structure provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
