[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The present invention provides an embodiment of a measuring ruler comprising a square 1 and an angle display 2. A slot 3 is formed in the middle of the square 1, with scales on both sides. The square 1 is made of transparent plastic for easy viewing. The rear side of the square 1 is slidably connected to the front side of the angle display 2. The square 1 measures with the angle display 2 as the center, and the angle display 2 displays the measured angle in real time.

[0033] Slide 4 is slidably connected to the interior of chute 3, which is part of the square 1. This chute 3 guides the movement of slider 4, allowing the user to easily slide a pen into it for drawing. Pointers 5 are fixedly attached to the top and bottom of slider 4. The rear side of pointer 5 slides onto the front side of square 1. From behind slider 4, pointer 5 slides onto the scale of square 1. This design allows the user to clearly see the measurement results, facilitating operation.

[0034] refer to Figure 2 、 Figure 3 Slider 4 is provided with an outer ring groove 6 to accommodate other components. Four through-holes 7 are provided around the outer ring groove 6. Clamping blocks 8 are slidably connected to the inner walls of through-holes 7. Clamping blocks 8 are used to secure a pen placed in slider 4, preventing it from sliding while drawing. This design takes into account the shapes and sizes of different pens to provide better adaptability.

[0035] The inner wall of outer ring groove 6 is slidably connected to limit blocks 9. Springs 10 are located in the middle of the four limit blocks 9. The side of the limit block 9 facing away from spring 10 is fixedly connected to the side of the clamping block 8 facing spring 10. The combination of limit blocks 9 and spring 10 ensures that the clamping block 8, to which the limit blocks 9 are fixedly connected, can provide appropriate clamping force when needed. This design allows the limit blocks 9 to flexibly switch between fixed and released positions, facilitating user operation.

[0036] Spring 10 is sleeved on the outside of the slider 4. The spring 10 is a ring-shaped spring wrapped around the outside of the slider 4. The external bottom end of the angle display 2 is fixedly connected to a limiter 11. The limiter 11 is an auxiliary measuring ruler for measuring the horizontal position of a straight line. The external angle display 2 is fixedly connected to a protractor 12. The protractor 12 is made of transparent material. The front bottom end of the angle display 2 is fixedly connected to an angle sensor 13. The sensor is used to measure the rotation angle of the square ruler 1 in real time. The external angle sensor 13 is fixedly connected to a limit ring 14. The front end of the limit ring 14 is provided with a limit component for fixing the angle display 2 and the square ruler 1. The limit ring 14 is designed to connect the limit component.

[0037] refer to Figure 4 、 Figure 5 The limiting assembly includes a second spring 15. The front end of the limiting ring 14 is fixedly connected to the rear end of the second spring 15. The front end of the second spring 15 is fixedly connected to a conical block 16. The second spring 15 limits the position of the conical block 16. The outer portion of the conical block 16 is slidably connected to the limiting cylinder 17, achieving the positioning and sliding of the limiting cylinder 17. The outer portion of the conical block 16 engages with the inner wall of the chute 3 to connect the square 1 and the angle indicator 2.

[0038] Limiting slots 18 are provided on both the upper and lower sides of the center of the limiting cylinder 17. A roller 19 is slidably connected to the interior of the limiting slot 18, limiting the sliding distance of the roller 19. A telescopic rod 20 is rotatably connected to the exterior of the roller 19. Spring 3 21 is sleeved around the exterior of the telescopic rod 20 to ensure that the roller 19 can be reset. Spring 2 15 is sleeved around the exterior of spring 3 21 to prevent the two components from interfering with each other. The top end of spring 3 21 is fixedly connected to the rear end of the conical block 16, while the other end of spring 3 21 is fixedly connected to the front end of the rotation angle sensor 13 to ensure that the conical block 16 can be reset. A sliding hole pull rod 22 is fixedly connected to the top and bottom ends of the roller 19. The interior of the middle portion of the sliding hole pull rod 22 is slidably connected to the exterior of the conical block 16. The sides of the sliding hole pull rod 22 are tapered, with a long through-slot provided in the middle.

[0039] A bubble level 23 is fixedly connected to the middle of the front end of the angle display 2. The bubble level 23 is installed in the middle of the front end of the angle display 2 to ensure that the device remains level during measurement. The design of this part can effectively avoid measurement errors caused by the tilt of the device. A display screen 24 is provided on the top side of the front end of the angle display 2. The data monitored by the rotation angle sensor 13 provided in the angle display 2 will be transmitted to the display screen 24 for the user to view. Its accuracy directly affects the accuracy of the measurement. A record button 25 is provided at the front end of the angle display 2. The record button 25 is used to record the measured data. The user only needs to press it lightly to save the current measurement value. Its design is simple and clear, making it more convenient for the user to operate.

[0040] Working principle: When in use, first place the object to be measured on the desktop, and then use the limit piece 11 of the angle display 2 to press against the corner of the desktop. At this time, you can pull the right-angle ruler 1 with the conical block 16 as the center, slide it in a straight line, or rotate it at multiple angles, and then place the sealed pen or pens of different sizes in the slider 4. By squeezing the clamping block 8, the clamping block 8 drives the limit block 9 to push the spring 10 to deform, thereby achieving a fixing effect. Then, by fixing the chalk and pen to slide in the slide groove 3, you can draw straight lines or arcs, helping users to better grasp the shape and proportion of objects.

[0041] When the measuring ruler is used to measure angles or draw arcs of different lengths, the square ruler 1 can be fixed to a horizontal position in advance by the bubble level 23, and then the distance between the square ruler 1 and the tapered block 16 can be adjusted according to one's own needs. Then, the sliding hole pull rod 22 can be moved to allow the conical surface of the side of the sliding hole pull rod 22 to rotate around the roller 19 through the sliding hole opened by the sliding hole pull rod 22 until it slides to the top of the limit cylinder 17. At this time, the roller 19 and the spring three 21 will retract and press against the limit ring 14, and the limit cylinder 17 will be pressed backward by the sliding hole pull rod 22, so that the outer conical surface of the limit cylinder 17 presses against the sliding groove 3 opened in the square ruler 1 to achieve a fixing effect. After fixing, the square ruler 1 is rotated again to establish a connection between the square ruler 1 and the angle sensor 13, so that the angle sensor 13 can measure the rotation angle of the square ruler 1 in real time, and the measured data will be displayed on the display screen 24. Finally, the user can press the record button 25 to record and retain the measured data.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
