Description

Technical Field

[0001] This utility model belongs to the field of measuring ruler technology, specifically relating to a ruler with a line drawing and limiting function. Background Technology

[0002] A ruler, also known as a measuring ruler or graduated ruler, is a tool used to draw line segments (especially straight ones) and measure lengths. Rulers usually have graduations on them to measure lengths.

[0003] Authorized publication number "CN220742569U" discloses a ruler with a line-drawing limiting function, including a ruler body and a first drawing edge disposed on the ruler body. The first drawing edge has a first scale line with a first reference position. The ruler body has a first limiting part, one side of which is aligned with the first reference position. With this ruler, when drawing lines, the user first finds the desired scale position and begins drawing, then draws along the scale line to the limiting position, i.e., to the first reference position. This first limiting part helps the user more accurately control the endpoints when drawing lines, effectively avoiding the problem of "drawing beyond the line's edge" and improving the accuracy and consistency of the drawing.

[0004] The aforementioned novel first limiting part can help users control the endpoints more accurately when drawing lines, but each time a line of the same length is drawn, the required scale position needs to be found again and the line drawing can begin. This increases the steps and time consumption in the workflow, and this method may be inefficient for situations where lines of the same length need to be drawn frequently. Utility Model Content

[0005] The purpose of this invention is to provide a ruler with a line-drawing limit function, which aims to solve the problem in the prior art that the required scale position needs to be found again and the line drawing needs to start each time a line of the same length is drawn.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ruler with a line-drawing and limiting function includes:

[0008] Measuring ruler;

[0009] The limiting mechanism includes an upper pressing groove, a distance adjustment groove, a distance adjustment plate, a marking limiting plate, multiple marking limiting grooves, a marking limiting block, and a distance scale. The upper pressing groove is located at the upper end of the measuring scale. The distance adjustment groove is located at one side of the upper pressing groove and is connected to the upper pressing groove. The distance adjustment plate is slidably connected within the distance adjustment groove. The marking limiting plate is fixedly connected to one side of the distance adjustment plate. Multiple marking limiting grooves are located on the upper inner wall of the distance adjustment groove. The marking limiting block is located at the upper end of the marking limiting plate and matches the multiple marking limiting grooves. The distance scale is located at the upper end of the measuring scale.

[0010] As a preferred embodiment of this utility model, a sliding pressing block is fixedly connected to one side end of the distance adjustment plate. The sliding pressing block slides in the upper pressing groove. A spring sleeve is provided at the lower end of the sliding pressing block. The sliding pressing block slides at the upper end of the spring sleeve. A reset spring is fixedly connected to the lower end of the sliding pressing block and the lower inner wall of the spring sleeve.

[0011] In a preferred embodiment of this utility model, a limiting groove is provided at the upper end of the measuring ruler, and a limiting slider is fixedly connected to the lower end of the sliding pressing block, with the limiting slider sliding within the limiting groove.

[0012] As a preferred embodiment of this utility model, a pushing protrusion is fixedly connected to the upper end of the sliding pressing block, and the pushing protrusion is made of rubber.

[0013] As a preferred embodiment of this utility model, the positions of the plurality of line-marking limiting grooves are all matched with the marking positions of the distance scale.

[0014] As a preferred embodiment of this utility model, the length and width of the line-drawing limiting block match the line-drawing limiting groove, and the line-drawing limiting groove and the line-drawing limiting block are in concave-convex fit.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this solution, for situations where lines of the same length need to be drawn frequently, the device can preset the required length through its limiting function. Once the specific length is set, the user only needs to place the ruler and draw the line directly along the limiting device in subsequent operations. There is no need to repeatedly search for the scale position, which greatly reduces preparation time and improves drawing efficiency. It is especially suitable for work scenarios such as engineering design and architectural drawings that require precise and repetitive drawing of lines of the same length.

[0017] 2. In this solution, the limit function can be used to ensure that the length of the lines drawn each time is completely consistent, reducing the length difference caused by human error such as visual judgment error or unstable hand movements, and ensuring the accuracy and aesthetics of the drawings.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] A ruler with a line-drawing and limiting function includes:

[0030] Measuring ruler 1;

[0031] The limiting mechanism includes an upper pressing groove 2, a distance adjustment groove 3, a distance adjustment plate 4, a marking limiting plate 5, multiple marking limiting grooves 6, a marking limiting block 7, and a distance scale 8. The upper pressing groove 2 is located at the upper end of the measuring scale 1. The distance adjustment groove 3 is located at one side of the upper pressing groove 2 and is connected to the upper pressing groove 2. The distance adjustment plate 4 is slidably connected in the distance adjustment groove 3. The marking limiting plate 5 is fixedly connected to one side of the distance adjustment plate 4. Multiple marking limiting grooves 6 are all located on the upper inner wall of the distance adjustment groove 3. The marking limiting block 7 is located at the upper end of the marking limiting plate 5 and matches the multiple marking limiting grooves 6. The distance scale 8 is located at the upper end of the measuring scale 1.

[0032] In a specific embodiment of this utility model, the ruler includes a measuring ruler 1 and a limiting mechanism disposed therein. The measuring ruler 1 serves as the main structure and is used to realize conventional measurement and line drawing functions. The distance adjustment plate 4 can move laterally within the distance adjustment groove 3 and can also move up and down a short distance. A line drawing limiting plate 5 is fixedly connected to one side of the distance adjustment plate 4 to limit and support the pen, thereby keeping the pen stable and moving along a set direction during the line drawing process. Multiple line drawing limiting grooves 6 are evenly provided on the upper inner wall of the distance adjustment groove 3, and a line drawing limiting plug 7 is provided at the upper end of the line drawing limiting plate 5. The line drawing limiting plug 7 can be inserted into any one of the line drawing limiting grooves 6, thereby locking the position of the line drawing limiting plate 5. By inserting into different line-drawing limit slots 6, precise control of the line width or spacing can be achieved. A distance scale 8 is also provided at the upper end of the measuring ruler 1. The distance scale 8 corresponds to the position of multiple line-drawing limit slots 6, allowing users to accurately set the required limit position according to the scale, improving the intuitiveness and accuracy of use. When line drawing limit is required, the user can determine the required limit position by observing the distance scale 8, and then manually adjust the line-drawing limit plate 5 so that the line-drawing limit plug 7 is inserted into the corresponding line-drawing limit slot 6. At this time, the line-drawing limit plate 5 is fixed, and the line drawing operation can begin. If the limit position needs to be changed, simply pull the line-drawing limit plug 7 out of the current line-drawing limit slot 6, slide the line-drawing limit plate 5 to the target position again, and then insert it again to complete the adjustment.

[0033] Please refer to the details. Figures 1-6 A sliding pressing block 9 is fixedly connected to one side of the distance adjustment plate 4. The sliding pressing block 9 slides in the upper pressing groove 2. A spring sleeve 10 is provided at the lower end of the sliding pressing block 9. The sliding pressing block 9 slides at the upper end of the spring sleeve 10. A reset fixing spring 11 is fixedly connected to the lower end of the sliding pressing block 9 and the lower inner wall of the spring sleeve 10.

[0034] In this embodiment: A sliding pressing block 9 is fixedly connected to one side of the distance adjustment plate 4. The sliding pressing block 9 can slide along the length direction of the measuring ruler 1 in the upper pressing groove 2, so that the user can manually push the sliding pressing block 9 to move the drawing line limiting plate 5 to the desired position. A reset fixing spring 11 is fixedly connected between the lower end of the sliding pressing block 9 and the lower inner wall of the spring sleeve 10. The reset fixing spring 11 provides an upward elastic force. When no external force is applied, it can lift the sliding pressing block 9, thereby inserting the drawing line limiting plug 7 into the corresponding drawing line limiting groove 6, realizing the automatic locking of the drawing line limiting plate 5. When it is necessary to adjust the limiting position, the user only needs to press the sliding pressing block 9 down to make the drawing line limiting plug 7 disengage from the current drawing line limiting groove 6, and then slide the drawing line limiting plate 5 horizontally to the target position and release the press. The reset fixing spring 11 will automatically spring back the sliding pressing block 9, so that the drawing line limiting plug 7 is reinserted into the new drawing line limiting groove 6, completing the switching of the limiting position.

[0035] Please refer to the details. Figures 1-6 A limiting groove 12 is provided at the upper end of the measuring ruler 1, and a limiting slider 13 is fixedly connected to the lower end of the sliding pressing block 9. The limiting slider 13 slides within the limiting groove 12.

[0036] In this embodiment, the cooperation structure between the limiting slider 13 and the limiting groove 12 can effectively prevent the sliding pressing block 9 from shifting or shaking during the sliding process, ensuring that the drawing limiting plate 5 maintains stable operation during the adjustment process, and improving the overall operation accuracy and tactile experience.

[0037] Please refer to the details. Figures 1-6 The upper end of the sliding pressing block 9 is fixedly connected to a pushing protrusion 14, which is made of rubber.

[0038] In this embodiment: A push protrusion 14 is fixedly connected to the upper end of the sliding press block 9. The push protrusion 14 protrudes from the top surface of the sliding press block 9, making it easy for the user to apply force with their fingers to press or slide. The push protrusion 14 is made of rubber material, which has good elasticity and coefficient of friction. It can effectively increase the friction between the hand and the push protrusion 14 during operation, prevent slippage, and improve the stability and comfort of operation.

[0039] Please refer to the details. Figures 1-6 The positions of the multiple marked limit grooves 6 all match the marked positions of the distance scale 8.

[0040] In this embodiment, the positions of the multiple line-marking limiting grooves 6 are all matched with the marking positions of the distance scale 8. In practical applications, the units can be centimeters or millimeters. This design allows users to quickly and accurately determine the position of the line-marking limiting grooves 6 by observing the markings on the distance scale 8, thereby achieving precise marking or measurement of the required dimensions.

[0041] Please refer to the details. Figures 1-6 The length and width of the line-drawing limiting insert 7 match the line-drawing limiting groove 6, and the line-drawing limiting groove 6 and the line-drawing limiting insert 7 are in a concave-convex fit.

[0042] In this embodiment: by ensuring that the dimensions of the line drawing limiting plug 7 and the line drawing limiting groove 6 are precisely matched, the position can be fixed with high accuracy. This ensures that the position of each mark is highly consistent when performing line drawing operations. The concave-convex design increases the friction between the two, so that the plug will not easily move or slide out of the groove during the line drawing process, thus improving the stability and reliability of use.

[0043] The working principle and usage process of this utility model are as follows: When line drawing is required, the user can determine the required limit position by observing the distance scale 8. The user presses down on the sliding pressing block 9 to disengage the line drawing limit plug 7 from the current line drawing limit groove 6. Then, the user slides the line drawing limit plate 5 horizontally to the target position and releases the press. The reset fixing spring 11 will automatically push the sliding pressing block 9 back, allowing the line drawing limit plug 7 to re-insert into the new line drawing limit groove 6. At this time, the line drawing limit plate 5 is fixed, and the line drawing operation can begin.

[0044] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
