Description
Technical Field
[0001] The utility model relates to the technical field of amblyopia treatment, in particular to a comprehensive amblyopia treatment instrument. Background Art
[0002] In the treatment of amblyopia, a moving sight mark image is often used to move back and forth behind the eyepiece to achieve amblyopia training. However, in the existing reciprocating motion structure, shaking is unavoidable, which affects the stability of the sight mark movement, affects the effect of training, and also affects the recovery of amblyopia patients. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a comprehensive treatment instrument for amblyopia in view of the above-mentioned technical deficiencies. A belt and a slide rail are used in combination on the reciprocating motion path, so that the sight mark mechanism itself will not be subjected to twisting forces in other directions during the reciprocating motion, thereby avoiding the occurrence of shaking. At the same time, a worm and worm wheel structure is adopted on the output shaft of the motor, so that after being driven to a certain position, the position can be fixed by the self-locking structure of the worm wheel and the worm, thereby avoiding slipping, and no energy support is required to achieve a specific position.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a machine body; an eyepiece is arranged on one side of the machine body; a sight mark mechanism that moves linearly along the eyepiece is arranged in the machine body; the sight mark mechanism is arranged in the machine body through a reciprocating motion structure; the reciprocating motion structure includes a slide rail that is linearly arranged along the eyepiece toward the machine body; and an annular belt that is arranged parallel to the slide rail; the sight mark mechanism is slidably connected to the slide rail; the sight mark mechanism is fixedly connected to the belt; the annular belt is arranged in the machine body through pulleys at both ends; and a motor that is arranged on one side of the pulley for driving the belt to rotate; a worm is arranged on the output shaft of the motor; and a worm wheel that meshes with the worm is arranged on one side of the pulley axis.
[0005] To further optimize the technical solution, a position sensor is provided on one side of the sight mark mechanism in the linear motion direction.
[0006] To further optimize the technical solution, the sight mark mechanism includes a base box and a sight mark box that is inserted into the base box and can be pulled out.
[0007] To further optimize the technical solution, the bottom box is provided with an observation port on one side of the eyepiece.
[0008] Compared with the prior art, the utility model has the following advantages: 1. The belt and the slide rail are used in combination on the reciprocating motion path. This structure advantageously ensures that the sight mark mechanism itself will not be subjected to twisting forces in other directions during the reciprocating motion, thereby avoiding the occurrence of shaking; 2. The worm and worm wheel structure on the motor output shaft advantageously ensures that after being driven to a certain position, the position is fixed by the self-locking structure of the worm wheel and the worm, thereby avoiding slipping, and no energy support is required to achieve a specific position.

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0014] Specific implementation method: Combination Figure 1-3 As shown, it includes a body 1; an eyepiece 2 is arranged on one side of the body 1; a sight mark mechanism 3 that moves linearly along the eyepiece 2 is arranged in the body 1; the sight mark mechanism 3 is arranged in the body 1 through a reciprocating motion structure; the reciprocating motion structure includes a slide rail 4 that is linearly arranged along the eyepiece 2 to the body 1; and an annular belt 5 that is arranged parallel to the slide rail 4; the sight mark mechanism 3 is slidably connected with the slide rail 4; the sight mark mechanism 3 is fixedly connected with the belt 5; the annular belt 5 is arranged in the body 1 through pulleys 6 at both ends; and a motor 7 that is arranged on one side of the pulley 6 for driving the belt 5 to rotate; a worm 8 is arranged on the output shaft of the motor 7; a worm wheel 9 that meshes with the worm 8 is arranged on one axial side of the pulley 6; a position sensor 10 is arranged on the side of the linear motion direction of the sight mark mechanism 3; the sight mark mechanism 3 includes a bottom box 11 and a sight mark box 12 that is inserted in the bottom box 11 and can be pulled out; the bottom box 11 is provided with an observation port 13 on one side of the eyepiece 2.
[0015] When using, combine Figure 1-3 As shown, the worm 8 is driven to rotate by the motor 7, which in turn drives the worm wheel 9 to rotate, which in turn drives the pulley 6 and the belt 5, and then drives the entire sight mark mechanism 3 to reciprocate along the distance between the slide rail 4 and the eyepiece 2. During the reciprocating motion, since the sight mark mechanism 3 is only driven by the belt 5 along the direction of the slide rail 4, circumferential shaking is avoided, thereby ensuring the stability of the sight mark mechanism 3 during the movement, so that when observing in the eyepiece 2, the shaking of the picture during the reciprocating motion is reduced.
