Description

Technical Field

[0001] The present invention belongs to the technical field of vision therapy devices, and particularly relates to a mobile light source device for a myopia therapy instrument. Background Art

[0002] In vision correction instruments, most use two treatment units to treat different eyes separately. The two units are isolated in different lens barrels respectively, thus forming a double-lens barrel therapy instrument. Due to the certain differences in the pupillary distances of each person and the different light powers of the light sources required by users, during use, the distance between the two lens barrels and the light power of the light source usually need to be adjusted simply to meet the needs of different users. There are many problems with the common double-lens barrel devices on the market at present:

[0003] (1) For users, different users have different pupillary distances. The fixed distance between the lens barrels results in the same fixed spot distance, which may not be able to match the pupillary distances of all users, and the spots cannot cover the entire pupil.

[0004] (2) The lens barrels are fixedly connected without a limit cover plate or a fixed bracket. During the transportation of the product, shaking and collision may cause jitter during the period, resulting in non-parallel or variable distances between the two spots.

[0005] (3) The light source base is a fixed light source, the distance is not adjustable, and it is difficult to adjust the light power of the light source. Summary of the Invention

[0006] The purpose of the present invention is to provide a mobile light source device for a myopia therapy instrument, which solves the problems of non-adjustable distance between the lens barrels and difficult adjustment of the light power of the light source existing in the existing myopia therapy instruments.

[0007] The technical solution adopted by the present invention is that a mobile light source device for a myopia therapy instrument includes a left lens barrel fixing member and a right lens barrel fixing member. The left lens barrel fixing member and the right lens barrel fixing member are respectively embedded with a left lens barrel and a right lens barrel. A toothed plate a extending towards the right lens barrel fixing member is connected to the left lens barrel fixing member, and a toothed plate b extending towards the left lens barrel fixing member is connected to the right lens barrel fixing member. The tooth shapes of the toothed plate a and the toothed plate b are opposite, and a gear shaft is meshed between the toothed plate a and the toothed plate b. It further includes a fixed bracket. The gear shaft passes through the fixed bracket. The fixed bracket is vertically connected to two limiting plates. The toothed plate a and the toothed plate b are located between the two limiting plates. It also includes an L-shaped cover plate covering the left lens barrel fixing member and extending towards the right lens barrel fixing member. One side edge of the L-shaped cover plate is fixedly connected to the fixed bracket. The other side edge of the L-shaped cover plate is integrally connected with a sliding convex platform. Fixed blocks are connected to the left lens barrel fixing member and the right lens barrel fixing member. Sliding grooves a are opened at the positions of the two fixed blocks facing the sliding convex platform. The sliding convex platform is slidably connected to the sliding grooves a. A cover plate is connected to one side of the L-shaped cover plate. The L-shaped cover plate and the cover plate are on the same horizontal plane. A mobile light source base is connected to the cover plate. The mobile light source base cooperates with the left lens barrel and the right lens barrel respectively.

[0008] The features of the present invention also lie in that:

[0009] The mobile light source base includes a light source cylinder and a light cylinder A which are respectively sleeved with the left lens barrel and the right lens barrel. A sliding plate is movably connected to the surface of the cover plate. Long strip holes corresponding to the light source cylinder and the light cylinder A are respectively opened on both sides of the surface of the cover plate. Sliders cooperating with the long strip holes are respectively arranged on both sides of the bottom of the sliding plate. The sliders are respectively movably connected to the light source cylinder and the light cylinder A. A light source is connected to one end of the light source cylinder and the light cylinder A away from the left lens barrel and the right lens barrel;

[0010] The light source cylinder and the light cylinder A are respectively coaxially and movably connected to the left lens barrel and the right lens barrel through sleeves;

[0011] The slider is respectively movably connected to the light source cylinder and the light cylinder A through telescopic rods. The telescopic rods are parallel to the cover plate and perpendicular to the light source cylinder and the light cylinder A;

[0012] A dial plate perpendicular to the cover plate is further arranged on the cover plate;

[0013] The left lens barrel fixing member and the right lens barrel fixing member both include two semi-circular clips. One ends of the two semi-circular clips are hinged, and the other ends are connected through fastening bolts. The left lens barrel and the right lens barrel are located inside the two semi-circular clips;

[0014] The fixing bracket is respectively provided with a sliding groove b facing the toothed plate a and the toothed plate b. The toothed plate a and the toothed plate b respectively slide along the sliding groove b.

[0015] One end of the gear shaft passes through the fixing bracket and is connected to a rotating gear.

[0016] It further includes a U-shaped bracket that contacts and covers the rotating gear in the middle. Both ends of the U-shaped bracket are fixedly connected to the fixing bracket.

[0017] The beneficial effects of the present invention are:

[0018] For the mobile light source device of the myopia treatment instrument of the present invention, the left lens barrel fixing member and the right lens barrel fixing member of the fixed lens barrel are guided and limited on both sides through the L-shaped cover plate, preventing the problem that the lens barrel is prone to swing during adjustment, and improving the stability of the lens barrel adjustment.

[0019] The mobile light source device of the myopia treatment instrument of the present invention has the following advantages:

[0020] 1. By rotating the gear shaft to drive the toothed plate a and the toothed plate b to move in two directions, and simultaneously driving the left lens barrel fixing member and the right lens barrel fixing member to move in opposite directions, the distance between the left lens barrel fixing member and the right lens barrel fixing member is increased or decreased, and the distance between the lens barrels can be manually adjusted to match the pupil distances of different users, improving the user experience of the users; the distance adjustment device is adjusted manually by rotation, which is convenient for fine adjustment, easy to control the precision, convenient to use, simple in structure, and low in manufacturing cost;

[0021] 2. The light source base adopts a movable light source base, which can adjust the light source back and forth according to the light power required by the user, so that the light power of the light source required by the user can be adjusted manually and quickly. The dial can be slid arbitrarily to drive the light cylinder to displace. The telescopic connection between the slider and the light cylinder can ensure that the adjustment of the lens barrel spacing is not affected. Brief Description of the Drawings

[0027] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0028] The present invention discloses a mobile light source device for a myopia treatment instrument, which mainly includes two parts: a pupil distance adjustment device and a movable light source base device, specifically as follows:

[0029] As Figure 3 and Figure 4As shown, the interpupillary distance adjustment device specifically includes a left lens barrel fixing member 1 and a right lens barrel fixing member 2. The left lens barrel fixing member 1 and the right lens barrel fixing member 2 are used to fix the two lens barrels. The left lens barrel fixing member 1 is connected to a toothed plate a3 extending toward the right lens barrel fixing member 2, and the right lens barrel fixing member 2 is connected to a toothed plate b4 extending toward the left lens barrel fixing member 1. The tooth shapes of the toothed plates a3 and b4 are opposite to each other. A gear shaft 5 is meshed between the toothed plates a3 and b4. The device also includes a fixed bracket 6. The gear shaft 5 passes through the fixed bracket 6. The gear shaft 5 can rotate at a constant position under the constraint of the fixed bracket 6. Since the position of the gear shaft 5 remains unchanged, when the gear shaft 5 rotates, the positions of the meshed toothed plates a3 and b4 can be driven to change, thereby realizing the position adjustment of the left lens barrel fixing member 1 and the right lens barrel fixing member 2, and then realizing the relative position adjustment of the two lens barrels. It also includes an L-shaped cover plate 8 covering the left lens barrel fixing part 1 and the right lens barrel fixing part 2. One side of the L-shaped cover plate 8 is fixedly connected to the fixing bracket 6, and the other side is integrally connected to the sliding boss 13. The left lens barrel fixing part 1 and the right lens barrel fixing part 2 are connected to the fixing block 10. The two fixing blocks 10 are provided with a sliding groove a12 facing the sliding boss 13. The sliding boss 13 is slidably connected in the sliding groove a12. The L-shaped cover plate 8 plays a limiting role on the fixing block 10, which can prevent the fixing block 10 from deviating from the original moving position. The fixing bracket 6 is provided with a sliding groove b facing the toothed plate a3 and the toothed plate b4 respectively. The toothed plate a3 and the toothed plate b4 slide along the sliding groove b respectively. The sliding groove b is used to limit the toothed plate a3 and the toothed plate b4, so that the toothed plate a3 and the toothed plate b4 can move in the original direction when moving under the action of the gear;

[0030] The width of the L-shaped cover plate 8 is not less than the width of the fixed bracket 6 and the fixed block 10 side by side, and can limit the moving direction of the fixed block 10 when in use. Since the fixed block 10 is fixedly connected to the left lens barrel fixing member 1 and the right lens barrel fixing member 2, the stability of the left lens barrel fixing member 1 and the right lens barrel fixing member 2 when moving is further increased, and the problem of easy swinging of the lens barrel when adjusting is prevented;

[0031] The fixed bracket 6 vertically connects the two limit plates 7, and the toothed plate a3 and the toothed plate b4 are located between the two limit plates 7. The two limit plates 7 can support the toothed plates a3 and the toothed plates b4.

[0032] The gear shaft 5 passes through one end of the fixed bracket 6 and is connected to the rotating gear 9. The rotation of the gear shaft 5 can be controlled by rotating the rotating gear 9.

[0033] The left lens barrel fixing member 1 and the right lens barrel fixing member 2 each include two semicircular clamps, one end of the two semicircular clamps are hinged, and the other end is connected by a fastening bolt 14, each lens barrel is placed between the two semicircular clamps, and then fixed by the fastening bolt 14;

[0034] It further includes a U-shaped bracket 11 that contacts and covers the rotating gear 9 in the middle. Both ends of the U-shaped bracket 11 are fixedly connected to the fixed bracket 6. The U-shaped bracket 11 can limit the rotation of the rotating gear 9. When the rotating gear 9 is manually rotated, the rotating gear 9 rotates relative to the U-shaped bracket 11.

[0035] As Figure 1 and Figure 2 shown, it is the core part of this device, a movable light source base, which specifically includes a light source cylinder 18 and a light source cylinder A19 that are movably connected to the left lens barrel 16 and the right lens barrel 17 in the interpupillary distance adjusting device through a sleeve 24. The sleeve 24 can not only connect the lens barrel and the light source cylinder, but also play a limiting role. The adjusting part includes a cover plate 15 that is connected in the same plane as the L-shaped cover plate 8. Both the light source cylinder 18 and the light source cylinder A19 are located below the cover plate 15. Long strip holes 21 parallel to the light source cylinder 18 and the light source cylinder A19 are opened at the corresponding parts on both sides of the surface of the cover plate 15. A sliding plate 20 is laid on the cover plate 15. Sliders 22 are respectively provided at both ends of the sliding plate 20 and are matched with the long strip holes 21. The sliders 22 can move and displace within the long strip holes 21. The sliders 22 are respectively connected to the light source cylinder 18 and the light source cylinder A19 through telescopic rods. The telescopic rods are perpendicularly arranged to the light source cylinder 18 and the light source cylinder A19. The purpose is to adjust the distance according to the binoculars synchronously when the interpupillary distance adjusting device adjusts the binocular distance. The sliders 22 can drive the light source cylinder 18 and the light source cylinder A19 to displace along their axial directions, so as to adjust the distance between the light source 23 and the pupil, and thus adjust the light power of the light source. The dial 25 allows the user to freely adjust the light source distance to meet the required light power of the user.

[0036] The usage method of the movable light source device for the myopia treatment instrument of the present invention is as follows:

[0037] During use, align the eyes with the two lens barrels. When the distance between the lens barrels needs to be adjusted, rotate the gear shaft 5 of the rotating gear 9 to drive the toothed plate a3 and the toothed plate b4 to move in opposite directions respectively, and at the same time drive the lens barrels in the left lens barrel fixing member 1 and the right lens barrel fixing member 2 to move in opposite directions, so that the distance between the left lens barrel fixing member 1 and the right lens barrel fixing member 2 becomes larger or smaller, thereby realizing the adjustment of the distance between the left lens barrel fixing member 1 and the right lens barrel fixing member 2. Due to the limiting effect of the limiting groove a and the limiting groove b, the toothed plate a3 and the toothed plate b4 can move in the set direction, and the stability during use is good. When the user needs to adjust the light power of the light source according to his own needs, the light distance can be adjusted through the dial 25 until the light power of the light source that meets his use is adjusted.

[0038] Through the above method, in the mobile light source device of the myopia treatment instrument of the present invention, the rotation of the gear shaft drives the toothed plate a and the toothed plate b to move in two directions, and at the same time drives the left lens barrel fixing member and the right lens barrel fixing member to move in opposite directions, so that the distance between the left lens barrel fixing member and the right lens barrel fixing member becomes larger or smaller. Manually adjusting the lens barrel distance can match the pupil distance of different users, improving the user experience of the user; the movable light source seat can meet the need to adjust the light source distance at any time according to the user, so as to achieve the purpose of adjusting the light power of the light source. The distance adjustment device and the movable light source seat device of the present invention are adjusted by manual movement, which is convenient for fine adjustment, easy to control the accuracy, easy to use, simple in structure, and low in manufacturing cost.
