Description

Technical Field

[0001] This utility model relates to the field of laser therapy device technology, and in particular to a light guide arm for a laser therapy device. Background Technology

[0002] Laser therapy devices are the main instruments used in laser therapy. They utilize a light guide arm to refract light multiple times before finally emitting it from the port.

[0003] In existing light guide arms, a positioning light tube and an extension light tube are set on them to adjust the position of the treatment head. Most of them are adjusted by moving a slider between the positioning light tube and the extension light tube. With long-term use, the two are prone to loosening, which can cause the position of the positioning light tube and the extension light tube to be offset. This can lead to the position of the treatment head being offset, affecting the accuracy of the treatment and thus the treatment effect.

[0004] Therefore, we propose a light guide arm for a laser therapy device. Utility Model Content

[0028] Example 1: A laser therapy device light guide arm, such as Figure 1 and Figure 2 As shown, including

[0029] The treatment device body 1 has an electrical signal connection at one end to a light guide arm body 2, which includes a positioning light tube 3, an extension light tube 4, and a treatment head 5.

[0030] The positioning component is located at the positioning optical tube 3 and the extension optical tube 4. The positioning component includes a first fixing ring 6, an adjusting rod 7 and a second fixing ring 8.

[0031] A locking assembly is provided inside the first fixing ring 6 to lock the adjusting rod 7. The locking assembly includes an extension rod 15, a clamping plate 17 and a fixing rod 18. The first fixing ring 6 is provided with an adjusting part for adjusting the position of the clamping plate 17. The adjusting part includes a gear ring 12, a sliding seat 13, a bevel gear 14 and an adjusting screw 16.

[0032] The positioning light tube 3 is located at the tail end of the light guide arm body 2. The extension light tube 4 is slidably connected inside the positioning light tube 3. The treatment head 5 is located at the tail end of the extension light tube 4. The first fixing ring 6 is sleeved and fixed on the outer wall of the positioning light tube 3. The first fixing ring 6 has multiple circumferentially arranged sliding holes 9. The adjusting rod 7 is slidably connected in the inner wall of the sliding hole 9. The second fixing ring 8 is fixedly connected to the tail end of the adjusting rod 7 and sleeved and fixedly connected to the outer wall of the extension light tube 4.

[0033] When it is necessary to adjust the position of the extension light tube 4 and the treatment head 5, the position of the extension light tube 4 and the treatment head 5 can be adjusted by sliding the extension light tube 4 within the positioning light tube 3. At this time, the movement of the extension light tube 4 can drive the adjusting rod 7 to slide in the sliding hole 9 within the first fixing ring 6 through the second fixing ring 8, and the extension light tube 4 can be locked by the adjusting rod 7 and the second fixing ring 8.

[0034] like Figure 3 and Figure 4 As shown, the fixing rod 18 is fixedly connected to one end of the inner wall of the sliding hole 9. The first fixing ring 6 has an annular adjustment groove, and the adjustment groove has multiple sliding grooves arranged in a circle. The extension rod 15 is slidably connected to the inner wall of the sliding groove. The clamping plate 17 is fixedly connected to the opposite end of the extension rod 15 and the fixing rod 18. The clamping plate 17 has a semi-circular cross-section, and the inner diameter of the clamping plates 17 at both ends is adapted to the outer diameter of the adjustment rod 7.

[0035] like Figure 5 As shown, the sliding seat 13 is fixedly connected to the adjustment groove at the axis of the sliding groove. Limiting grooves 19 are opened at both ends of the sliding seat 13. Limiting sliders 20 are fixedly connected to the outer walls on both sides of the adjusting screw 16. The limiting sliders 20 are slidably connected to the inner wall of the limiting grooves 19.

[0036] When the adjusting screw 16 moves, the relative rotation between the adjusting screw 16 and the sliding seat 13 can be locked by the sliding of the limiting slider 20 in the limiting groove 19.

[0037] like Figure 4 As shown, the bevel gear 14 is fixedly connected to one end of the sliding seat 13 at an axial position. An adjusting screw 16 is fixedly connected to the bevel gear 14 at an axial position. The adjusting screw 16 is rotatably connected to the inner wall of the sliding seat 13 and threadedly connected to the inner wall of the adjusting screw 16.

[0038] The first fixed ring 6 has an annular rotating groove 10. A rotating rod 11 is rotatably connected in the rotating groove 10. The gear ring 12 is rotatably connected in the adjusting groove and meshes with the outer wall of the bevel gear 14. The rotating rod 11 is fixedly connected to one end of the gear ring 12.

[0039] When it is necessary to clamp and fix the adjusting rod 7, the rotating rod 11 drives the gear ring 12 to rotate, which in turn drives the bevel gear 14 meshing with it to rotate. The bevel gear 14, through the rotation of the extension rod 15, drives the adjusting screw 16 threadedly connected to it to slide in the sliding seat 13. The extension rod 15 then drives the clamping plate 17 to approach the clamping plate 17 on the fixing rod 18 to clamp and fix the adjusting rod 7. When it is necessary to unlock, simply rotate the rotating rod 11 in the opposite direction.

[0040] In summary, the positioning and locking components can support the relative position between the positioning light tube 3 and the extension light tube 4, improving the stability of their positions and preventing the extension light tube 4 from loosening due to shaking with the positioning light tube 3 during prolonged use. This would affect the stability of the treatment head 5, thereby affecting the accuracy of the treatment position and the treatment effect.

[0041] Example 2: Based on Example 1, with reference to Figure 6 Multiple elastic rings 21 arranged in a circular pattern are fixedly connected inside the clamping plate 17. The cross-section of the elastic rings 21 is semi-circular, and a spherical fixing groove is provided in the gap between the clamping plate 17 and the elastic rings 21. An elastic block 22 is fixedly connected to the inner wall of the fixing groove.

[0042] When the clamping plate 17 clamps and fixes the adjusting rod 7, it can contact the adjusting rod 7 by squeezing the elastic ring 21. The squeezing causes the elastic ring 21 to deform and fit against the outer wall of the adjusting rod 7, thereby increasing the friction between the elastic ring 21 and the adjusting rod 7.

[0043] The fixed groove has multiple buffer cavities 23 arranged in a circle. Two magnets 24 are installed in the buffer cavity 23. One magnet 24 is fixedly connected to the end of the buffer cavity 23 away from the fixed groove, and the other magnet 24 is slidably connected to the inner wall of the buffer cavity 23. The magnetic poles of the two magnets 24 are the same at opposite ends.

[0044] When the extended light tube 4 shakes, the clamping plate 17 is squeezed by the second fixing ring 8 and the adjusting rod 7. The elastic ring 21 on the clamping plate 17 deforms and squeezes the elastic block 22, causing the elastic block 22 to deform and enter the buffer cavity 23. This squeezes the magnet 24 in the buffer cavity 23, causing the two magnets 24 to move closer to each other. The magnetic poles can buffer the stress of the shaking.

[0045] By using the elastic ring 21, elastic block 22, and magnet 24, the stability of the position of the adjusting rod 7 is improved by increasing friction and magnetic force, thereby improving the stability of the extension light tube 4 and the treatment head 5.

[0046] The working principle of this utility model is as follows: When it is necessary to clamp and fix the adjusting rod 7, the rotating rod 11 drives the gear ring 12 to rotate, which in turn drives the bevel gear 14 meshing with it to rotate. The bevel gear 14, through the rotation of the extension rod 15, drives the adjusting screw 16 threadedly connected to it to slide in the sliding seat 13. The extension rod 15 drives the clamping plate 17 to move closer to the clamping plate 17 on the fixing rod 18 to clamp and fix the adjusting rod 7. When it is necessary to unlock, simply rotate the rotating rod 11 in the opposite direction. The second fixing ring 8 drives the adjusting rod 7 to slide in the sliding hole 9 to adjust the position of the extension tube 4.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
