Technical Field
[0001] This utility model belongs to the field of angle measurement technology, specifically, it is a corner angle measuring device. Background Technology
[0002] In existing technologies, most corner angles are simply measured using a protractor. However, for small corners, the protractor cannot be inserted into the corner. It is necessary to first insert two measuring plates into the two walls of the corner, then use bolts to fix the angle of the measuring plates, remove the measuring plates, and then measure with the protractor. The measurement process is quite cumbersome.
[0003] Therefore, the known methods for measuring wall corner angles have the aforementioned inconveniences and problems. Utility Model Content

Both the first and second operating panels are three-section hinged panels of unequal length. The end of the shortest first section is connected by a connecting pin. The middle section of the second panel is connected by a connecting pin through a connection point on the connecting plate. The longest third section is connected by a pivot pin, so that the first and second operating panels cooperate to form two mutually hinged first parallelograms and second parallelograms. A semi-circular protractor plate is provided on the upper surface of the first operating panel with the pivot pin as the center. The second operating panel has positioning marking lines that cooperate with the protractor plate to read the angle values on the protractor plate.

The middle of the long strip plate has a long groove, which serves as a sliding groove so that the end of the pin can enter the sliding groove and the pin can slide in the sliding groove.

[0010] In the aforementioned corner angle measuring device, the hinged plate with the shortest first segment is set as the measuring plate, and the measuring plate is attached to the wall surface when the corner angle measuring device is in use.

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings. Example
[0026] The corner angle measuring device of this utility model includes an operation panel 3 and a vertical plate 5.
[0027] Please see now Figures 1-6The operating plate 3 includes a first operating plate 31 and a second operating plate 32 that are hinged together. Both the first and second operating plates 31 and 32 are three-section hinged plates of unequal length. The end of the shortest first section is connected by a connecting pin. The middle section of the second operating plate is connected by a connecting pin through a connection point on the connecting plate 2. The longest third section is connected by a pivot pin 6, allowing the first and second operating plates 31 and 32 to cooperate to form two hinged first and second parallelograms. A semi-circular protractor plate 4 is provided on the upper surface of the first operating plate 31, centered on the pivot pin 6. The second operating plate 32 has positioning markings 41 for the protractor plate 4, allowing for reading angle values. The first parallelogram is larger than the second parallelogram. The pivot pin 6 includes a slider 61 and a limiting block 62. The protractor plate 4 has graduations indicating angles. The first hinged plate is the measuring plate 1, used to fit snugly against the wall during measurement, and has the shortest length. The connecting plate 2 is located between the second hinged plates, which are of intermediate length, and serves to connect and stabilize the structure.
[0028] The vertical plate 5 is a long strip plate with a through hole at one end. It is connected to the end of the first hinge plate with the shortest length by a connecting pin. The middle part of the long strip plate has a long groove, which serves as a sliding groove 51, allowing the end of the shaft pin 6 to enter the sliding groove and slide in the sliding groove. Example
[0029] The method of using the corner angle measuring device of this utility model is as follows: Insert the hinged ends of the two measuring plates 1 into the corner of the wall, so that the two measuring plates 1 are respectively in close contact with the two sides of the wall at the corner. By adjusting the included angle between the first operating plate 31 and the second operating plate 32 and pushing the slider 61 at the intersection of the connecting plate 2, the slider 61 at the intersection of the first operating plate 31 and the second operating plate 32 is positioned within the groove 51, so that the measuring plates 1 are completely in contact with the wall surface without gaps. At this time, a parallelogram frame is formed between the two measuring plates 1 and the two connecting plates 2. The longitudinal included angle of the intersection formed by the first operating plate 31 and the second operating plate 32 is equal to the included angle formed by the two measuring plates 1. By reading the scale value of the positioning mark 41 on the protractor 4, the longitudinal included angle of the intersection formed by the first operating plate 31 and the second operating plate 32 can be known. By obtaining the included angle value formed by the two measuring plates 1, the corner angle can be determined.
[0030] This utility model has substantial features and significant technological advancements. The corner angle measuring device of this utility model, in use, consists of two sets of measuring plates forming a V-shaped structure, two sets of operating plates forming an X-shaped structure, a part of a connecting plate forming a parallelogram with the V-shaped structure, and another part of the connecting plate forming a parallelogram with a part of the X-shaped structure. This allows the included angle of the X-shaped structure to characterize the included angle of the V-shaped structure. The corner angle can then be determined by measuring the included angle of the X-shaped structure with a protractor. For small corner angles, the protractor can also be used for direct measurement. The parallelogram formed by the measuring plate and the connecting plate is smaller than the parallelogram formed by the connecting plate and the first and second operating plates, allowing the measuring plate to accurately fit into the two walls at smaller corners, resulting in more accurate measurements. Furthermore, the large size of the first and second operating plates and the protractor facilitates operation, eliminating the need for post-calculation and directly obtaining the measurement result.
[0031] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various modifications and variations without departing from the spirit and scope of this utility model. Therefore, all equivalent technical solutions should also fall within the scope of this utility model and should be defined by the claims.
