Description
Technical Field
[0001] This utility model belongs to the field of stationery technology, and in particular relates to a vision training posture correction ruler. Background Technology
[0002] A vision training posture ruler is an assistive tool used to help improve eyesight and maintain correct reading posture. It is typically a ruler with markings that can be placed on a book or electronic device to help users maintain the proper reading distance and angle, reducing eye strain and preventing myopia.
[0003] In the prior art, the method of using a ruler with scales is as follows: The user places the scale line in a preset position, then attaches the pen tip to the edge of the ruler where the scale line is located, and draws a line segment of preset length along the scale line. When the length of the ruler is insufficient, the user moves the ruler so that it moves parallel to the already drawn line segment, so that the previous scale line moves backward, thereby extending the corresponding area of the scale line on the ruler so that the user can continue to draw, and thus be able to draw a line segment with a length greater than the maximum scale of the ruler.
[0004] However, during the process of the user moving the ruler to extend the drawing, since the ruler and the drawing surface are not in fixed contact, the user is prone to positional deviation when moving and aligning, resulting in an angular deviation between the extended line segment and the original line segment, which reduces the practicality of the posture ruler. Utility Model Content
[0005] The purpose of this utility model is to provide a vision training posture correction ruler, which aims to solve the technical problem in the prior art where, during the process of users moving the ruler to extend and draw, positional deviations easily occur when users move and align, resulting in angular deviations between the extended line segment and the original line segment.
[0006] To achieve the above objectives, this utility model provides a vision training posture correction ruler, including a body, a first sliding component, and a second sliding component. The body is provided with a first sliding groove, and the first sliding component is slidably connected within the first sliding groove. The first sliding component is provided with a second sliding groove, and the second sliding component is disposed within the second sliding groove. The first sliding groove and the second sliding groove are arranged perpendicularly, and the end of the second sliding component can extend outside the first sliding groove and is tightly attached to the bearing surface of the body.
[0007] Optionally, the first sliding assembly includes a first movable seat and an elastic component. The first movable seat is slidably connected in the first slide groove and can reciprocate in the length direction of the first slide groove. The second slide groove is formed on the inner wall of the first movable seat. The elastic component is disposed in the second slide groove. The first movable seat and the body can move relative to each other through the first slide groove.
[0008] Optionally, the elastic component includes an elastic movable seat and an elastic element. The elastic movable seat is disposed in the second slide groove and can reciprocate along the length direction of the second slide groove. The elastic element is disposed in the second slide groove. The elastic movable seat is fixedly connected to the side wall of the second sliding assembly. The two ends of the elastic element abut and adapt to the inner wall of the elastic movable seat and the second slide groove, respectively.
[0009] Optionally, the second slide groove includes a through groove and a side groove. The through groove passes through the first movable seat, and the side groove is formed on the inner wall of the through groove. The second sliding assembly is slidably adapted to the through groove, the elastic movable seat is slidably connected in the side groove, and the elastic element is disposed in the side groove.
[0010] Optionally, the number of the elastic movable seat, the elastic element and the side groove is two sets, the two sets of the second sliding groove are mirror-formed at both ends of the through groove, the two sets of the elastic movable seats are slidably connected to the corresponding side grooves, and the two sets of the elastic elements are respectively disposed in the corresponding side grooves.
[0011] Optionally, the second sliding assembly includes a second movable seat and a buffer component. The second movable seat is slidably connected in the second slide groove, and the buffer component is disposed at the bottom of the second movable seat. When the second movable seat moves along the second slide groove, the buffer component moves with the second movable seat and extends outside the first slide groove and the second slide groove. The second movable seat is connected to an elastic component.
[0012] Optionally, the thickness of the second movable seat is greater than the depth of the second slide groove, at least a portion of the second movable seat always extends outside the second slide groove, and the buffer member is located inside the second slide groove when the end of the second movable seat away from the buffer member is located outside the second slide groove.
[0013] Optionally, the buffer component includes at least one set of abutment rings, which are made of rubber or silicone material and are all concentrically arranged.
[0014] Optionally, the buffer component is a ring-shaped suction cup.
[0015] Optionally, the body has scale lines along its length direction on its edge, and the length direction of the scale lines is parallel to the length direction of the first groove.
[0016] The vision training posture correction ruler provided in this embodiment of the present invention has at least one of the following technical effects: The user first drives the first sliding component to the end of the first slide groove away from the starting position of the scale line. The user presses the body with their finger and traces a line segment along the scale line. When the trace is close to the limit position of the scale line, the user presses the second sliding component towards the drawing end face, so that the second sliding component moves along the second slide groove until the end of the second sliding component is in close contact with the drawing end face. At this time, the user keeps the first sliding component and the second sliding component fixed in place and drives the ruler body to move along the length direction of the first slide groove until the first sliding component and the first slide groove are in close contact. The other end of the slide groove abuts, and the user draws an extended line segment on the scale line along the edge of the moved ruler. Compared with the existing technology, where the user moves the ruler to extend the drawing, the user is prone to positional deviation when moving and aligning, resulting in an angular deviation between the extended line segment and the original line segment. The vision training posture correction ruler provided in this embodiment fixes the main body and the second sliding component in sequence, so that the first sliding component and the ruler move parallel to each other along the scale line direction. During the movement, the ruler is always parallel to the line segment that has been drawn before. The line segment drawn by this posture correction ruler is uniformly collinear, which effectively improves the practicality of the vision training posture correction ruler.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0038] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0039] In one embodiment of this utility model, such as Figures 1-10 As shown, a vision training posture correction ruler is provided, including a body 100, a first sliding component 200, and a second sliding component 300. The body 100 is provided with a first sliding groove 400, and the first sliding component 200 is slidably connected within the first sliding groove 400. The first sliding component 200 is provided with a second sliding groove 500, and the second sliding component 300 is disposed within the second sliding groove 500. The first sliding groove 400 and the second sliding groove 500 are perpendicularly arranged, and the end of the second sliding component 300 extends beyond the first sliding groove 400 and is tightly fitted against the bearing surface of the body 100. The body 100 has graduation lines 600 along its length, and the length direction of the graduation lines 600 is parallel to the length direction of the first sliding groove 400.
[0040] like Figures 1-10 As shown, in this embodiment, the body 100 is arranged in the shape of a rectangular plate. The length direction of the first sliding groove 400 is arranged along the length direction of the body 100. The first sliding groove 400 penetrates the body 100. The edge of the first sliding component 200 is provided with a protrusion 700. The inner sidewall of the first sliding groove 400 is provided with a guide groove 800. The protrusion 700 and the guide groove 800 are slidably adapted to each other.
[0041] like Figures 1-2As shown, the user first drives the first sliding component 200 to the end of the first slide groove 400 away from the starting position of the scale line 600. The user presses the body 100 with their finger and traces a line segment along the scale line 600. When the line is close to the limit position of the scale line 600, the user presses the second sliding component 300 towards the drawing end face, causing the second sliding component 300 to move along the second slide groove 500 until the end of the second sliding component 300 is in close contact with the drawing end face. At this time, the user keeps the first sliding component 200 and the second sliding component 300 in fixed positions and drives the ruler to move along the length direction of the first slide groove 400 until the first sliding component 200 and the other side of the first slide groove 400 are in contact. The end of the ruler is abutted, and the user draws an extended line segment on the scale line 600 along the edge of the ruler after it has been moved. Compared with the prior art, where the user is moving the ruler to extend the drawing, the user is prone to positional deviation when moving and aligning, resulting in an angular deviation between the extended line segment and the original line segment. The vision training posture correction ruler provided in this embodiment fixes the main body 100 and the second sliding component 300 in sequence, so that the first sliding component 200 and the ruler move parallel to each other along the scale line 600. During the movement, the ruler is always parallel to the line segment that has been drawn earlier. The line segment drawn by this posture correction ruler is uniformly collinear, which effectively improves the practicality of the vision training posture correction ruler.
[0042] like Figures 1-10 As shown, in another embodiment of the present invention, the first sliding component 200 includes a first movable seat 210 and an elastic member 220. The first movable seat 210 is slidably connected in the first slide groove 400 and can reciprocate in the length direction of the first slide groove 400. The second slide groove 500 is formed on the inner wall of the first movable seat 210. The elastic member 220 is disposed in the second slide groove 500. The first movable seat 210 and the body 100 can move relative to each other through the first slide groove 400.
[0043] like Figures 1-10 As shown, in another embodiment of this utility model, the elastic component 220 includes an elastic movable seat 221 and an elastic element 222. The elastic movable seat 221 is disposed within the second slide groove 500 and is capable of reciprocating along the length direction of the second slide groove 500. The elastic element 222 is disposed within the second slide groove 500. The elastic movable seat 221 is fixedly connected to the side wall of the second sliding assembly 300. The two ends of the elastic element 222 respectively abut against and are adapted to the elastic movable seat 221 and the inner wall of the second slide groove 500. In this embodiment, the elastic element 222 is a compression spring, and the two ends of the compression spring abut against the inner wall of the second slide groove 500 and the end of the elastic movable seat 221 respectively.
[0044] like Figures 1-10 As shown, in another embodiment of this utility model, the second sliding groove 500 includes a through groove 510 and a side groove 520. The through groove 510 penetrates the first movable seat 210, and the side groove 520 is formed on the inner wall of the through groove 510. The second sliding assembly 300 is slidably adapted to the through groove 510. The elastic movable seat 221 is slidably connected in the side groove 520, and the elastic member 222 is disposed in the side groove 520. The end of the elastic member 222 abuts against the bottom wall of the side groove 520.
[0045] like Figures 1-10 As shown, in another embodiment of this utility model, the number of the elastic movable seat 221, the elastic element 222, and the side groove 520 are two sets. The two sets of second sliding grooves 500 are mirror-formed at both ends of the through groove 510. The two sets of elastic movable seats 221 are slidably connected to the corresponding side grooves 520, and the two sets of elastic elements 222 are respectively disposed in the corresponding side grooves 520. Using two sets of elastic elements 222 is beneficial to improving the movement stability of the second sliding component 300 and improving the tight contact effect between the second sliding component 300 and the drawing end face.
[0046] like Figures 1-10 As shown, in another embodiment of this utility model, the second sliding component 300 includes a second movable seat 310 and a buffer component 320. The second movable seat 310 is slidably connected within the second slide groove 500. The buffer component 320 is disposed at the bottom of the second movable seat 310. When the second movable seat 310 moves along the second slide groove 500, the buffer component 320 moves with the second movable seat 310 and extends outside the first slide groove 400 and the second slide groove 500. The second movable seat 310 is connected to the elastic component 220. The thickness of the second movable seat 310 is greater than the depth of the second slide groove 500. At least a portion of the second movable seat 310 always extends outside the second slide groove 500. When the end of the second movable seat 310 away from the buffer component 320 is outside the second slide groove 500, the buffer component 320 is located within the second slide groove 500, allowing the user to accurately press the second movable seat 310 and improving operational convenience.
[0047] like Figures 1-10As shown, in another embodiment of this utility model, the buffer component 320 includes at least one set of abutment rings, which are made of rubber or silicone material and are all concentrically arranged. In this embodiment, the number of abutment rings is one set. The abutment rings with silicone or rubber structures, when deformed, form an air cavity structure because their ground surface is in close contact with the drawing end face. When the second moving seat 310 presses the abutment rings against the drawing end face, a suction cup effect is formed. This prevents the buffer component 320 from shifting position after being pressed, and the rubber structure helps to buffer the pressure and prevent damage to the drawing end face. Specifically, when the user applies pressure to the second moving seat 310, the elastic element 222 drives the second moving seat 310 to reset, thereby causing the second moving seat 310 to move the buffer component 320 away from the drawing end face. In other embodiments, the buffer component 320 can also be a ring-shaped suction cup.
[0048] like Figures 1-10 As shown, in another embodiment of this utility model, the first movable seat 210 is made of a magnetically conductive metal material, and a magnetic element 900 is provided on the body 100. The magnetic element 900 is located at the end of the first sliding groove 400. The magnetic element 900 can generate a magnetic force on the first movable seat 210 so that the first movable seat 210 can be quickly reset.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
