DETAILED DESCRIPTION
[0024] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.
[0025] Example 1, a portable multi-angle measuring angle ruler, such as Figures 1-6 As shown, it includes a measuring plate 1, a scale plate 2, a magnet frame 3, a first movable ruler 4, a guide block 5, a first rotating ruler 6, a second movable ruler 7, a second rotating ruler 71, a magnetic plate 8 and a measuring assembly.

A measuring assembly is provided on the measuring plate 1.
[0026] like Figure 3 and Figure 4 As shown, the first rotating ruler 6 and the second rotating ruler 71 are both made of metal iron.
[0027] like Figure 5 and Figure 6As shown, the measuring assembly includes a rotating frame 9, a rubber block 91, a hinged plate 92, a handle 10, a contact rod 11, a spring 111 and a display screen 12. The right side of the measuring plate 1 is rotatably connected to the rotating frame 9, and the front side of the rotating frame 9 is fixed with a rubber block 91. The rubber block 91 is squeezed and fitted with the measuring plate 1. The measuring plate 1 is provided with a slot for the rubber block 91 to pass through. The bottom of the measuring plate 1 is rotatably connected to the hinged plate 92 through a damping ring. The right side of the rotating frame 9 is fixed with a handle 10. The interior of the rotating frame 9 is slidably connected to the contact rod 11. A spring 111 is fixed between the contact rod 11 and the rotating frame 9. An opening for the contact rod 11 to slide out is provided on the rear side of the rotating frame 9. The right front side of the measuring plate 1 is fixed with a display screen 12, and the display screen 12 is electrically connected to the rotating frame 9.
[0028] like Figure 5 and Figure 6 As shown, the right side of the handle 10 is provided with serrated stripes distributed vertically up and down.
[0029] like Figure 6 As shown, the rear side of the contact rod 11 is provided with a curved surface.
[0030] The following is the specific usage method. Please note that the various position descriptions that appear during use, such as "left", "right", "up", and "down", are all in Figure 1 The top surface in the plan view angle is used as a reference, and the side where the hinge plate 92 is provided is a side parallel to the bottom surface.
[0031] When a worker needs to measure an angle, if the angle to be measured is relatively common, the worker can first slide the first movable ruler 4 to the right by an appropriate distance, and then rotate the first rotating ruler 6 clockwise until it contacts the magnetic plate 8 and is adsorbed and fixed. At this time, the first rotating ruler 6 and the hypotenuse of the upper right corner of the measuring plate 1 are on the same straight line. Since the measuring plate 1 is bilaterally symmetrical, and the angles of the three corners on both sides of the measuring plate 1 are 135°, 120° and 105° from top to bottom, the hypotenuse of the lower right corner of the measuring plate 1, the first movable ruler 4 and the first rotating ruler 6 can be combined to form a triangle, and the three corners of this triangle are aligned. The angles are 45°, 60° and 75° respectively. Then, the second movable ruler 7 can be moved obliquely upward by an appropriate distance, and the second rotating ruler 71 can be rotated counterclockwise until it contacts the magnetic plate 8 and is adsorbed and fixed. At this time, the top edge of the measuring plate 1, the second movable ruler 7 and the second rotating ruler 71 will form an isosceles right triangle. After that, the angle formed by the combination of each component can be directly compared with the angle to be measured. In this way, various common angles such as 45°, 75° and 120° can be quickly measured. After the measurement is completed, the components can be moved in the opposite direction or rotated until they are reset.
[0032] If the angle to be measured is not a common angle that can be measured comparatively, the measuring plate 1 can be first attached to the workpiece to be measured, and the hinged plate 92 can be turned back 180 degrees to contact the bottom of the workpiece. At this time, the bottom edge of the measuring plate 1 and the bottom edge of the angle to be measured are on the same straight line, and the entire device is located above the angle to be measured. Movement in all directions on the plane will not cause contact or collision with the angle to be measured, and there will be no interference to prevent its components from unfolding for measurement.
[0033] After the bottom edge of the measuring plate 1 is determined, the measuring plate 1 is moved left and right along this bottom edge until the axis of rotation of the rotating frame 9 coincides with the vertex of the angle to be measured. After that, the rubber block 91 can be pulled out to unlock the rotating frame 9, and then the rotating frame 9 is rotated to the right and opened by the handle 10. The contact rod 11, because it is no longer restricted by the measuring plate 1, will move backward under the action of the spring 111 and pop out from the opening on the rear side of the rotating frame 9. Next, the rotating frame 9 is rotated again so that the contact rod 11 contacts the other side of the angle to be measured. At this time, the display screen 12 will display the angle formed by the rotating frame 9 and the bottom edge of the measuring plate 1, that is, the angle of the angle to be measured. This is a mechanical reading, and there is no error caused by human eye reading.
[0034] If the angle to be measured is small, the first movable ruler 4 can be pulled out to the right, and the angle to be measured can be simulated by the first movable ruler 4 and the first rotating ruler 6. The complementary angle of the smaller angle can then be measured in reverse by the rotating frame 9, and the angle to be measured can be calculated, thereby realizing the measurement of smaller angles. In this way, various uncommon angles can be measured quickly and accurately.
[0035] After the measurement is completed, the hinged plate 92, the rotating frame 9, the handle 10 and other components are rotated in the opposite direction to reset, and then the first movable ruler 4 is moved to the left to reset. During this period, the contact rod 11 will contact the measuring plate 1 and be squeezed to move forward and reset. The spring 111 is then compressed, and the rubber block 91 can also enter the slot on the measuring plate 1 after reset, and limit and fix the rotating frame 9 and the handle 10 and other components. During measurement, if the workpiece to be measured is iron, the magnet frame 3 can absorb the workpiece to avoid offset between the measuring plate 1 and other components and the workpiece during measurement, thereby affecting the measurement results. The hole in the middle of the magnet frame 3 also makes it convenient for workers to take and carry this angle ruler.
[0036] Example 2, based on Example 1, Figure 5 and Figure 7As shown, it also includes a tape measure 13, a rotating ring 131, a torsion spring 14, a back plate 15 and a magnetic block 151. The rotating ring 131 is rotatably connected to the middle of the magnet frame 3, and the torsion spring 14 is fixed between the rotating ring 131 and the magnet frame 3. The tape measure 13 is wrapped around the outside of the rotating ring 131. The tape measure 13 is slidably connected to the measuring plate 1. The end of the tape measure 13 away from the rotating ring 131 is fixedly connected to the back plate 15, which is slidably connected to the measuring plate 1, and the magnetic block 151 is fixed to the middle of the back plate 15.
[0037] When a worker needs to measure the length, he can measure it through the scale plate 2 on the measuring plate 1. If the measuring range of the scale plate 2 is insufficient, the tape measure 13 can be pulled out through the butt plate 15, and the rotating ring 131 will rotate immediately, and the torsion spring 14 will also deform immediately. Then, the butt plate 15 can be used to hook the edge of the workpiece and measure. If the workpiece is made of iron, the butt plate 15 can be fixed to the workpiece through the magnetic block 151 before measuring. After the measurement is completed, release the butt plate 15 and the magnetic block 151, and the rotating ring 131 will rotate in the opposite direction and reset under the action of the torsion spring 14, thereby rewinding the tape measure 13, and the butt plate 15 and the magnetic block 151 will also return to their original position as the tape measure 13 is retracted.
