Description

Technical Field

[0001] This utility model relates to the field of mobile phone adapter technology, specifically to a joint locking structure for a mobile phone adapter. Background Technology

[0002] In the current mobile phone adapter market, especially for adapters used with professional equipment such as surgical microscopes, the design often has many limitations. Traditional mobile phone adapters mostly lack flexible joint rotation design, resulting in a fixed usage position, failing to meet diverse and multi-angle shooting or observation needs, relatively simple functions, and a poor user experience.

[0003] To improve adapter flexibility and user experience, some products have attempted to incorporate joint rotation designs. However, these designs often employ relatively simple structures, such as relying solely on damping grease to control the joint's rotational force. While this design achieves joint rotation to some extent, it has significant drawbacks. Firstly, the control precision of damping grease is limited; once the product is manufactured, the joint rotational force is essentially fixed, making it difficult to adjust flexibly according to actual needs. If the joint rotational force is too heavy, users will find it difficult to rotate, resulting in inconvenience and severely impacting the user experience. Conversely, if the joint rotational force is too light, it cannot effectively maintain the joint position, causing the device to wobble during use and become unstable. Utility Model Content

[0004] The purpose of this invention is to provide a joint locking structure for a mobile phone adapter, thereby solving the problem mentioned in the background art, such as relying solely on damping grease to control the rotational force of the joint. While this design achieves joint rotation to a certain extent, it has significant drawbacks.

[0005] To achieve the above objectives, this utility model provides a joint locking structure for a mobile phone adapter, including a lens barrel. One end of the lens barrel is rotatably connected to a first lens body via a first rotating shaft. One end of the first lens body is rotatably connected to a second lens body via a second rotating shaft. A lens is mounted on one end of the second lens body. A damping knob is mounted on the outer side of the first lens body. A first clamp is fitted on the outer side of the connection between the first lens body and the lens barrel. A second clamp is fitted on the outer side of the connection between the first lens body and the second lens body. The damping knob can be tightened or loosened by turning the knob.

[0006] Preferably, a fixed bracket is installed at the bottom of the lens.

[0007] Preferably, a lens is installed at one end of the second mirror body, and right-angle prisms are installed inside the first and second mirror bodies. The first and second mirror bodies reflect the image incident on the lens tube twice at right angles before it is emitted from the lens.

[0008] Preferably, a first push rod is provided on one side of the damping knob near the first clamp, and a second push rod is provided on the other side of the damping knob near the second clamp.

[0009] Preferably, the outer wall of the damping knob is in contact with one end of the first push rod and the second push rod, respectively, and the position is adjusted by the knob to push the first push rod and the second push rod.

[0010] Preferably, the other end of the first push rod is provided with a bevel, and the outside of the notch of the first clamp is provided with a bevel. After the first push rod is subjected to the pressure of the damping knob, it pushes the notch of the first clamp to squeeze through the bevel, thereby locking and fixing one end of the lens barrel.

[0011] Preferably, the other end of the second push rod is provided with a bevel, and the outside of the notch of the second clamp is provided with a bevel. After the second push rod is subjected to the pressure of the damping knob, it pushes the notch of the second clamp to squeeze through the bevel, thereby locking and fixing one end of the second mirror body.

[0012] Preferably, the notch of the first clamp is fixed to the first mirror body on the side away from the first push rod, and the notch of the second clamp is fixed to the first mirror body on the side away from the second push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this mobile phone adapter's joint locking structure, the introduction of a first and a second pivot allows for 360° free rotation at both joints, significantly improving the adapter's flexibility and the versatility of shooting angles. Simultaneously, the damping knob, in conjunction with the design of the first and second clamps, enables precise adjustment and stable locking of the joint rotation force, ensuring the device remains stable and wobble-free during use.

[0015] The damping knob design allows users to easily adjust the joint's rotational force according to their needs. When joint rotation is required, a lighter touch can be applied for easier movement; when the joint needs to be locked in place, a heavier touch can be applied for stable locking. This design meets the needs of different usage scenarios and greatly enhances the user experience.

[0016] This structure can be adapted to more mobile phones of different weights. By adjusting the damping knob, it can effectively support and stabilize mobile phones of different weights, thus expanding the application range of the adapter.

[0017] By using a right-angle prism design, two right-angle reflections are achieved in the light path, ensuring the stability and clarity of the image during transmission. Furthermore, since the locking mechanism does not affect the relative position of the right-angle prism, it does not affect the optical axis of the optical system, thus ensuring stable image planes during multi-angle shooting with the mobile phone.

[0018] Compared to traditional designs that rely on damping grease to control rotational force, the mechanical structure design of this invention is more durable and reliable. The introduction of mechanical components such as damping knobs and clamps makes the product more stable during use, less susceptible to external environmental influences, and thus extends the product's service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a joint locking structure for a mobile phone adapter, such as... Figures 1-3As shown, the adapter includes a lens barrel 1. One end of the lens barrel 1 is rotatably connected to a first lens body 2 via a first pivot 11. One end of the first lens body 2 is rotatably connected to a second lens body 3 via a second pivot 31. A lens 5 is mounted on one end of the second lens body 3. A damping knob 4 is mounted on the outside of the first lens body 2. A first clamp 21 is fitted on the outside of the connection between the first lens body 2 and the lens barrel 1. A second clamp 22 is fitted on the outside of the connection between the first lens body 2 and the second lens body 3. The damping knob 4 can be turned to tighten or loosen the first clamp 21 and the second clamp 22. This ingenious design achieves both flexible joint rotation and stable locking. Specifically, the lens barrel 1 and the first lens body 2, as well as the first lens body 2 and the second lens body 3, are rotatably connected via the first pivot 11 and the second pivot 31, respectively. This design allows the entire adapter to easily adapt to different shooting or observation angles, greatly improving its flexibility and convenience.

[0026] More importantly, the damping knob 4 installed on the outer side of the first mirror body 2, along with the cooperating first clamp 21 and second clamp 22, together constitute a highly efficient locking mechanism. When the user needs to adjust the angle of the adapter, simply turning the damping knob 4 will reduce the clamping force on the first clamp 21 and second clamp 22 through its internal mechanical structure, allowing the joint to rotate smoothly. When the user needs to fix the position of the adapter, tightening the damping knob 4 will increase the clamping force on the clamps, causing the clamps to tightly hold the pivot and achieve stable locking of the joint.

[0027] This design not only ensures the stability and reliability of the adapter during use, preventing shooting or observation angle shifts caused by loose joints, but also provides users with great convenience, allowing them to easily adjust the adapter's angle according to actual needs and quickly lock it in the desired position. Therefore, the joint locking structure of this mobile phone adapter has significant technical effects in improving user experience and enhancing product stability and flexibility.

[0028] In this embodiment, a mounting bracket 6 is installed at the bottom of the lens 5. The mounting bracket 6 is used to connect to the mobile phone device, making it convenient to fix the mobile phone for shooting.

[0029] Specifically, a lens 5 is mounted at one end of the second lens body 3, and right-angle prisms are installed inside the first lens body 2 and the second lens body 3. The first lens body 2 and the second lens body 3 reflect the image incident from the lens tube 1 twice at right angles before it exits from the lens 5. This design ensures that the image incident from the lens tube 1 can be accurately emitted from the lens 5 after two right-angle reflections. This not only achieves precise control of the optical path but also ensures the clarity and stability of the image during transmission, providing users with a high-quality shooting or observation experience.

[0030] Furthermore, a first push rod 41 is provided on one side of the damping knob 4 near the first clamp 21, and a second push rod 42 is provided on the other side of the damping knob 4 near the second clamp 22. This design, through the cooperation of the push rod and the damping knob, achieves precise control of the clamp, providing a reliable mechanical basis for subsequent locking operations.

[0031] Furthermore, the outer wall of the damping knob 4 is respectively attached to one end of the first push rod 41 and the second push rod 42. The position is adjusted by turning the knob, and the first push rod 41 and the second push rod 42 are pushed. This design allows the user to achieve precise pushing of the push rod by simply turning the damping knob 4, thereby controlling the clamping tightness of the clamp and realizing flexible adjustment of the joint locking force.

[0032] Furthermore, the other end of the first push rod 41 is provided with a bevel, and the outer side of the notch of the first clamp 21 is also provided with a bevel. When the first push rod 41 is subjected to pressure from the damping knob 4, it pushes the notch of the first clamp 21 through the action of the bevel, thereby locking and fixing one end of the lens barrel 1. This design, through the ingenious use of the bevel, achieves rapid locking and stable fixing of the clamp, ensuring the stability and reliability of the joint in the locked state.

[0033] Furthermore, the other end of the second push rod 42 is provided with a bevel, and the outer side of the notch of the second clamp 22 is also provided with a bevel. When the second push rod 42 is subjected to pressure from the damping knob 4, it pushes the notch of the second clamp 22 through the action of the bevel, thereby locking and fixing one end of the second mirror body 3. When the second push rod 42 is subjected to pressure from the damping knob 4, it also pushes the notch of the second clamp 22 through the action of the bevel, thereby locking and fixing one end of the second mirror body 3. This design is similar to the locking mechanism of the first push rod and the first clamp, and together they constitute the core part of the entire joint locking structure, ensuring the stability and reliability of the entire structure.

[0034] Furthermore, the notch of the first clamp 21, on the side away from the first top rod 41, is fixed to the first lens body 2, and the notch of the second clamp 22, on the side away from the second top rod 42, is fixed to the first lens body 2. This design, through the tight fixation of the clamps to the lens body, further enhances the stability and rigidity of the entire structure, ensuring the stability and reliability of the joint during rotation and locking. At the same time, it also provides users with a more stable and reliable shooting or observation platform.

[0035] In use, the joint locking structure of this mobile phone adapter firstly connects the lens barrel 1 and the first lens body 2 via a first pivot 11, and then connects the first lens body 2 and the second lens body 3 via a second pivot 31. This design allows the entire adapter to rotate freely 360° at the two joints, easily adapting to different shooting or observation angles.

[0036] When the user needs to adjust the adapter angle, first turn the damping knob 4 to reduce the clamping force on the first clamp 21 and the second clamp 22 through its internal mechanical structure. At this time, the clamping force of the first clamp 21 and the second clamp 22 on the rotating shaft is reduced, and the joint becomes easier to rotate. When the user finds the desired angle and wants to fix the adapter position, turn the damping knob 4 again. This increases the clamping force on the first clamp 21 and the second clamp 22, making them hold the rotating shaft tightly, thereby achieving stable locking of the joint.

[0037] A first push rod 41 is provided on one side of the damping knob 4, and a second push rod 42 is provided on the other side. When the damping knob 4 is turned, its outer wall will push the first push rod 41 and the second push rod 42 respectively. The other end of the first push rod 41 and the second push rod 42 are provided with a bevel, which matches the bevel on the outside of the notch of the first clamp 21 and the second clamp 22. When the push rod is under pressure, it will push the notch of the clamp through the action of the bevel, thereby realizing the quick locking and stable fixation of the clamp.

[0038] A lens 5 is mounted at one end of the second lens body 3, and right-angle prisms are installed inside the first lens body 2 and the second lens body 3. The image incident on the lens tube 1 is accurately emitted from the lens 5 after two right-angle reflections. This design not only achieves precise control of the optical path, but also ensures the clarity and stability of the image during transmission through the reflection effect of the right-angle prism.

[0039] A mounting bracket 6 is installed at the bottom of lens 5. The mounting bracket 6 is used to connect to a mobile phone device, making it convenient to fix the phone for shooting. The notches of the first clamp 21 and the second clamp 22 are fixed to the first lens body 2 on the side away from the top rod. This design further enhances the stability and rigidity of the entire structure through the tight fixation of the clamps to the lens body.
