Description

Technical Field

[0001] This utility model relates to the field of woodworking equipment technology, specifically a woodworking angle ruler. Background Technology

[0002] A woodworking angle gauge is a crucial tool specifically designed to ensure angular accuracy during cutting, assembly, and other machining operations. Its core function is to allow users to set specific angles, ensuring all components are precisely cut or assembled at those angles. This capability significantly improves work efficiency and product quality, especially in operations requiring repeated use of the same angles. For example, when using power tools such as band saws and circular saws, the angle gauge acts as a guide, ensuring the cutting line not only remains straight but also strictly adheres to the set angle, thus reducing errors and improving consistency. To prevent angular deviations during operation, modern angle gauges are typically equipped with a reliable locking mechanism. Once the user sets the desired angle via the dial, it can be secured using a knob, screw, or other locking mechanism. This feature ensures that the set angle remains unchanged even in complex working environments, guaranteeing accuracy in every cut or assembly. A woodworking angle gauge is not only a key tool for achieving precise angle measurement but also a vital guarantee for improving overall work efficiency and product quality. Choosing a suitable angle gauge means choosing a more convenient, efficient, and professional woodworking experience.

[0003] Currently, angle gauges used in woodworking equipment generally rely on manual rotation of the handle to position and lock the angle. Traditional angle gauges used on woodworking equipment workbenches have several shortcomings: they are difficult to adjust precisely, the adjustment process is complex and prone to errors; and when locking after setting the angle, friction can easily cause angle deviations. Furthermore, the relative movement between the guide gauge and the guide groove of the woodworking equipment workbench involves metal-to-metal contact, which increases frictional resistance, making sliding less smooth, causing noise problems, and accelerating wear. Therefore, we propose a new type of woodworking angle gauge. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a woodworking angle ruler, including a guide ruler. Open adjustment rings are installed at both ends of the guide ruler with screws. An angle plate is rotatably connected to the upper surface of the guide ruler through a rotating shaft. A main support is fixedly connected to one side of the upper end of the angle plate. An arc-shaped groove is opened on one side surface of the angle plate. A locking handle is slidably connected inside the arc-shaped groove, and the lower end of the locking handle passes through the arc-shaped groove and is threadedly connected to the guide ruler.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, this utility model provides a woodworking angle ruler, including a guide ruler 2. Open adjustment rings 1 are screwed on both ends of the guide ruler 2. An angle plate 7 is rotatably connected to the upper surface of the guide ruler 2 through a rotating shaft 8. A main support 6 is fixedly connected to one side of the upper end of the angle plate 7. An arc groove 12 is opened on one side surface of the angle plate 7. A locking handle 9 is slidably connected inside the arc groove 12, and the lower end of the locking handle 9 passes through the arc groove 12 and is threadedly connected to the guide ruler 2.

[0024] Among them, a sliding backrest 3 is movably connected to one side of the main backrest 6. A sliding groove 13 is provided on one side of the sliding backrest 3. By setting the sliding groove 13, the locking button 5 can slide along the sliding groove 13, so that the position of the sliding backrest 3 can be adjusted.

[0025] Among them, the inner side of the main support 6 is connected to the square neck bolt with a locking button 5, and the locking button 5 passes through the main support 6 and is connected to the slide groove 13 by the square neck bolt.

[0026] One side of the main support 6 is threaded with an adjusting screw 4, which passes through the main support 6 and abuts against the sliding support 3. The adjusting screw 4 is used to fine adjust the verticality of the sliding support 3 to ensure precise alignment between the two.

[0027] The angle disk 7 has an angle scale line 14 on one side of its surface and a groove 15 at the bottom, which corresponds to the angle scale line 14. The angle scale line 14 is used to read the rotation angle intuitively.

[0028] Among them, the upper end of the guide ruler 2 is fixedly connected with a spring ball screw 11. The upper end of the spring ball screw 11 is movably connected to the bottom of the angle plate 7, and the spring ball screw 11 is snapped into the groove 15. By setting the spring ball screw 11, the groove 15 is used in conjunction with the spring ball screw 11. When a specific angle needs to be fixed, the head of the spring ball screw 11 will be embedded in the corresponding groove, thereby quickly and accurately positioning the required angle position.

[0029] The angle dial 7 has a pointer 10 on one side, and the bottom of the pointer 10 is fixedly connected to the guide ruler 2. By setting the pointer 10 and using it in conjunction with the angle scale 14, the accuracy of angle adjustment is improved.

[0030] Working Principle: In use, first install the guide ruler 2 into the guide groove of the woodworking equipment's workbench. Adjust the position of the opening adjustment ring 1 (made of rubber and plastic) using a countersunk screw to adjust its protrusion. This fine-tunes the gap between the two, reducing friction during sliding, improving operational comfort, reducing wear and noise levels, and ensuring a tight and smooth fit between the guide ruler 2 and the guide groove for stable movement during operation. Adjust the locking button 5 so that it slides along the slide groove 13, adjusting the position of the sliding support 3. Adjust the adjusting screw 4 on the main support 6 to ensure that the sliding support 3 is perpendicular to the workbench surface. Next, loosen the locking handle 9 to allow the angle disc 7 to rotate freely on the pivot 8. The back of the angle disc 7 has grooves 15 that match the scale on the front, allowing the spring ball screws 11 on the guide ruler 2 to engage in these grooves, achieving quick and precise angle positioning. Rotate the angle disc 7 as needed until the pointer 10 points to the desired angle scale. Once the desired angle is determined, tighten the locking handle 9 again to fix the position of the angle disc 7 relative to the guide ruler 2, ensuring that the angle remains constant throughout the cutting process. After completing all the above adjustment steps, the cutting operation can begin.
