Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring tools, and in particular to an adjustable measuring square. Background Technology
[0002] In machining, manufacturing, woodworking, and construction, a square is a commonly used measuring tool, primarily used to measure and mark right angles or angles smaller than right angles. Traditional squares are typically fixed-angle structures (such as 90-degree right-angle squares or 45-degree bevel squares), whose angles are not adjustable, making them suitable only for specific scenarios and unable to meet diverse measurement needs. Furthermore, the corner design of traditional squares makes them inconvenient to store. Utility Model Content
[0003] The purpose of this invention is to provide an adjustable measuring angle ruler, suitable for measuring right angles or angles smaller than right angles. The measuring angle can be adjusted as needed, and it is also easy to store.
[0004] To achieve the above objectives, this utility model provides an adjustable measuring angle ruler, including a fixed ruler and a rotating ruler rotatably mounted on one end of the fixed ruler; when the rotating ruler is rotated, a certain angle area is formed between the rotating ruler and the fixed ruler, and this angle area is the measuring area; the surfaces on the rotating ruler and the fixed ruler that form the measuring area are flat surfaces; a scale is provided on the fixed ruler around the axis of rotation of the rotating ruler; and scale indication marks are provided on the rotating ruler corresponding to the scale.
[0005] With the above structure, when storing, the rotating ruler can be rotated to make it flush with the fixed ruler, thus forming a straight structure for easy storage; when measuring, the angle between the rotating ruler and the fixed ruler can be accurately read by the cooperation of the dial and scale indicator marks, so as to realize the measurement of a specific angle.
[0006] Preferably, a worm gear device is also installed at the bottom of the fixed ruler; the worm gear device includes a base fixed to the bottom of the fixed ruler, a worm and a worm wheel rotatably installed inside the base; the worm wheel and the worm cooperate with each other; one end of the worm extends out of the base and is fixed with a knob; the axle of the worm wheel is fixed to the shaft. By rotating the knob, the user can precisely adjust the angle of the rotating ruler to achieve fine-tuning and meet the needs of high-precision measurement.
[0007] Preferably, the rotating ruler has a threaded hole on one side of the rotating shaft, and a locking bolt is screwed into the threaded hole, with the inner end of the locking bolt abutting against the fixed ruler. By tightening the locking bolt, the position of the rotating ruler can be fixed, preventing it from sliding during measurement and ensuring the stability of the measurement results.
[0008] Preferably, the upper part of the locking bolt is provided with a tightening head, and the tightening head is provided with anti-slip texture. The anti-slip texture design facilitates manual operation by the user, and the locking bolt can be easily tightened or loosened even in wet or oily environments.
[0009] Preferably, a rubber layer is provided at the contact point between the inner end of the locking bolt and the fixed ruler. The rubber layer increases the friction between the locking bolt and the fixed ruler, further preventing the rotating ruler from slipping, while also avoiding wear that may be caused by direct metal-to-metal contact.
[0010] Preferably, the intersection of the rotating ruler and the fixed ruler is always within the measurement area. This ensures the integrity of the measurement area and the accuracy of the measurement, and avoids interference from the worm gear mechanism.
[0011] Preferably, the width of the rotating ruler and the fixed ruler are the same. This makes the overall structure of the measuring base more harmonious, and easier for the user to hold and operate.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are:
[0013] This utility model, an adjustable measuring square with a folded state, solves the technical problems of existing squares where the measuring size cannot be adjusted and they are inconvenient to store. This utility model is suitable for measuring right angles or angles smaller than right angles, and the measuring angle can be adjusted as needed, and it is also easy to store.

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] The orientations mentioned in this specification are based on the orientation of the adjustable measuring square of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.
[0022] Example 1:
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, an adjustable measuring angle ruler includes a fixed ruler 1 and a rotating ruler 2 rotatably mounted on one end of the fixed ruler 1. When the rotating ruler 2 is rotated, a certain angle region is formed between the rotating ruler 2 and the fixed ruler 1, which is the measuring area A. The surfaces of the rotating ruler 2 and the fixed ruler 1 that form the measuring area A are flat; this ensures a flat contact surface during measurement and improves measurement accuracy. A scale 3 is provided on the fixed ruler 1 around the axis of rotation of the rotating ruler 2; a scale indicator mark 21 is provided on the rotating ruler 2 corresponding to the scale 3. Through the cooperation of the scale 3 and the scale indicator mark 21, the user can accurately read the angle between the rotating ruler 2 and the fixed ruler 1, achieving high-precision measurement.
[0024] A threaded hole is provided on one side of the rotating shaft on the rotating ruler 2. A locking bolt 22 is screwed into the threaded hole, and the inner end of the locking bolt 22 abuts against the fixed ruler 1. By tightening the locking bolt 22, the position of the rotating ruler 2 can be fixed to prevent it from sliding during the measurement process and to ensure the stability of the measurement results.
[0025] Furthermore, a tightening head 221 is provided on the upper part of the locking bolt 22, and the tightening head 221 is provided with anti-slip texture. The anti-slip texture design facilitates manual operation by the user, allowing easy tightening or loosening of the locking bolt 22 even in wet or oily environments. A rubber layer is provided at the contact position between the inner end of the locking bolt 22 and the fixed ruler 1. The rubber layer increases the friction between the locking bolt 22 and the fixed ruler 1, further preventing the rotating ruler 2 from slipping, while avoiding wear that may be caused by direct metal-to-metal contact.
[0026] Example 2:
[0027] like Figures 1-5 As shown in the figure, this embodiment is a further improvement on the first embodiment.
[0028] A worm gear device 4 is also installed at the bottom of the fixed ruler 1. The worm gear device 4 includes a base 41 fixed to the bottom of the fixed ruler 1, a worm 42 rotatably installed inside the base 41, and a worm wheel 43. The worm wheel 43 works in conjunction with the worm 42; one end of the worm 42 extends out of the base 41 and is fixed with a knob 44; the axle of the worm wheel 43 is fixed to the shaft. By rotating the knob 44, the user can precisely adjust the angle of the rotating ruler 2 to achieve fine-tuning and meet the needs of high-precision measurement.
[0029] Furthermore, by adjusting the widths of the rotating ruler 2 and the fixed ruler 1, the intersection of the two can always be located within the measurement area A, ensuring the integrity of the measurement area A and the accuracy of the measurement, and avoiding interference of the worm gear device 4 with the measurement.
[0030] Furthermore, the width of the rotating ruler 2 is the same as that of the fixed ruler 1, making the overall structure of the measuring base more coordinated and easier for users to hold and operate.
[0031] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
