Description

Technical Field

[0001] This utility model relates to the field of laser irradiation range control, and in particular to a laser uniformity control device. Background Technology

[0002] Laser medicine is the field that applies laser technology to various medical diagnostic and treatment procedures. Laser therapy has shown good therapeutic effects in treating a variety of diseases such as chronic pain, soft tissue injury, arthritis, and wound healing. Its treatment principle is based on the interaction between laser photons and biological tissues, which produces a biostimulation effect, promotes increased cell metabolic activity, improves tissue blood circulation, and thus stimulates and strengthens the natural healing process. In practical applications, a laser therapy device is a medical device that uses lasers of specific wavelengths to stimulate the human body for therapeutic purposes. It is characterized by high precision, controllable depth, and non-invasiveness.

[0003] Chinese Patent Application Publication No. CN202020207400.0 discloses a laser device. This design involves setting a support plate at the bottom of a sleeve, with a first cover plate and a second cover plate on both sides of the support plate. The first and second cover plates can rotate around the support plate. When the first and second cover plates rotate to the bottom of the support plate, they contact the mounting surface, facilitating the support plate and the sleeve on it to be supported and fixed. When the first and second cover plates rotate to the top of the sleeve, a storage and protection space is formed between the first and second cover plates and the support plate, facilitating the storage and protection of the sleeve after use. However, during laser therapy, it is not convenient to adjust the laser irradiation range, and it is not convenient for the user to irradiate the area to be treated evenly.

[0004] To address this, we propose a laser uniformity control device. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a laser uniformity control device. By adjusting the cooperation of various parts of the adjustment component, the light emitted by the laser body is adjusted, the scattered light is reflected, and the scattering tubes are concentrated together. This prevents the waste of light scattering and the damage caused by light scattering to areas that do not need to be illuminated by the light source. This ensures that the light source is always kept within the working range and improves the stability of the uniformity of the laser when it passes through the laser body.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A laser uniformity control device includes an adjustment component, with a laser body fixedly connected to the rear end of the adjustment component. The adjustment component includes a housing, the rear end of which is fixedly connected to the laser body. A circular ring is installed inside the housing, and multiple fixed blocks arranged at equal intervals are fixedly connected to the middle of the circular ring. The ends of the fixed blocks away from the circular ring are fixedly connected to the inner wall of the housing. An adjustment ring is rotatably connected to the rear end of the circular ring. Multiple sliders arranged at equal intervals are slidably connected to the front end of the circular ring. The sliders and fixed blocks are staggered. A sliding rod is fixedly connected to the rear end of each slider, passing through the rear end of the circular ring and extending into the interior of the adjustment ring. The sliding rod is slidably connected to the circular ring. An optical reflector is fixedly connected to the front end of the circular ring.

[0008] Furthermore, the front end of the ring is provided with multiple sliding grooves that are adapted to the slider. The sliding grooves pass through the inner and outer rings of the ring, and the slider is located inside the sliding groove. The slider is slidably connected to the sliding groove.

[0009] Furthermore, the rear end of the ring is provided with a through groove that is adapted to the slide bar. The through groove is connected to the slide bar, the slide bar passes through the through groove, and the slide bar is slidably connected to the through groove.

[0010] Furthermore, the front end of the adjusting ring is provided with an arc-shaped opening that matches the slide rod. The arc-shaped opening passes through both ends of the adjusting ring, and the slide rod passes through the arc-shaped opening. The slide rod is slidably connected to the arc-shaped opening.

[0011] Furthermore, a connecting cylinder is fixedly connected to the rear end of the adjusting ring, and a worm gear is fixedly connected to the rear end of the connecting cylinder.

[0012] Furthermore, a motor is fixedly connected inside the outer casing and located behind the connecting cylinder, and a worm gear is fixedly connected to the output end of the motor, with the worm gear rotatably connected to the inner wall of the outer casing.

[0013] Furthermore, the worm is located at the bottom end of the worm wheel, and the worm meshes with the worm wheel.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By adjusting the coordination of various components, the light emitted by the laser body is adjusted, the scattered light is reflected, and the scattering tubes are focused together. This prevents the waste of light scattering and the damage caused by light scattering to areas that do not need to be illuminated by the light source. This ensures that the light source is always kept within the working range and improves the stability of the uniformity of the laser when it passes through the laser body.

[0016] 2. Rotate the adjusting ring. During the rotation of the arc-shaped opening of the adjusting ring, it squeezes and drives the sliding rod. The sliding rod moves along the through groove to retract or expand. In turn, the sliding rod drives the slider to retract or expand along the groove. The slider drives the optical reflector to retract or expand. During the retraction or expansion of the optical reflector, the range of light source illumination can be adjusted, which makes it convenient for the user to adjust the range of laser irradiation according to the area to be treated.

[0017] 3. The motor, worm gear, and worm wheel work together to drive the connecting cylinder to rotate, which in turn drives the adjusting ring to rotate, thereby adjusting the optical reflector to retract. The motor can be connected to an external controller to achieve automation or semi-automation, improve intelligence, and allow the laser to be tuned to meet different treatment effects. The laser is safe to use as it is manually controllable, and can promote the development of portable, community-based, and home-based laser therapy devices. Attached Figure Description

[0027] Reference Figures 1-6 As shown, a laser uniformity control device for a laser in a preferred embodiment of the present invention includes an adjustment component 1, with a laser body 2 fixedly connected to the rear end of the adjustment component 1; the adjustment component 1 includes a housing 101, with the rear end of the housing 101 fixedly connected to the laser body 2, a circular ring 102 installed inside the housing 101, a plurality of fixed blocks 103 arranged at equal intervals fixedly connected to the middle of the circular ring 102, the end of the fixed block 103 away from the circular ring 102 fixedly connected to the inner wall of the housing 101, an adjustment ring 104 rotatably connected to the rear end of the circular ring 102, a plurality of sliders 109 arranged at equal intervals slidably connected to the front end of the circular ring 102, the sliders 109 and the fixed blocks 103 being staggered, a sliding rod 111 fixedly connected to the rear end of the sliders 109, the sliding rod 111 passing through the rear end of the circular ring 102 and extending into the interior of the adjustment ring 104, the sliding rod 111 being slidably connected to the circular ring 102, and an optical reflector 110 fixedly connected to the front end of the circular ring 102.

[0028] Reference Figure 2-Figure 3 As shown, the front end of the ring 102 has multiple grooves that are adapted to the slider 109. The grooves pass through the inner and outer rings of the ring 102. The slider 109 is located inside the groove and is slidably connected to the groove.

[0029] The rear end of the ring 102 is provided with a through groove that is adapted to the slide rod 111. The through groove is connected to the slide groove, and the slide rod 111 passes through the through groove and is slidably connected to the through groove.

[0030] The front end of the adjusting ring 104 has an arc-shaped opening that matches the slide rod 111. The arc-shaped opening passes through both the front and rear ends of the adjusting ring 104, and the slide rod 111 passes through the arc-shaped opening. The slide rod 111 is slidably connected to the arc-shaped opening.

[0031] The rear end of the adjusting ring 104 is fixedly connected to the connecting cylinder 105, and the rear end of the connecting cylinder 105 is fixedly connected to the worm gear 106.

[0032] A motor 107 is fixedly connected inside the housing 101 and behind the connecting cylinder 105. A worm gear 108 is fixedly connected to the output end of the motor 107. The worm gear 108 is rotatably connected to the inner wall of the housing 101.

[0033] The worm 108 is located at the bottom end of the worm wheel 106, and the worm 108 meshes with the worm wheel 106.

[0034] Specific implementation process: First, when it is necessary to adjust the uniformity of the laser emitted by the laser, the motor 107 starts working. The output end of the motor 107 drives the worm 108 to rotate. Since the worm 108 meshes with the worm wheel 106 and the worm 108 is located at the bottom end of the worm wheel 106, the rotation of the worm 108 will drive the worm wheel 106 to rotate. The rotation of the worm wheel 106 will drive the connecting cylinder 105 and the adjusting ring 104 connected to the connecting cylinder 105 to rotate. During the rotation of the adjusting ring 104, the arc-shaped opening at its front end will exert a squeezing or pulling effect on the slide rod 111. Since the slide rod 111 is slidably connected to the through groove on the ring 102, the slide rod 111 will slide along the through groove. The groove moves, which in turn drives the slider 109 to retract or expand within the groove at the front end of the ring 102. The movement of the slider 109 drives the optical reflector 110 to retract or expand accordingly. When the laser passes through the laser body 2, the light that might have been scattered will be reflected by the optical reflectors 110 at different positions. By adjusting the retraction or expansion, the optical reflectors 110 can refocus the scattered light, thereby effectively preventing waste caused by light scattering and avoiding damage to non-irradiated areas caused by light scattering. This ensures that the laser source is always kept within the working range and improves the stability of the uniformity of the laser when passing through the laser body 2.
