Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a sheet material angle measuring tool. Background Art
[0002] Hardware sheets refer to thin sheets used in various hardware products and are widely used in various industrial fields. These sheets can be cut, bent, punched, welded and processed according to different uses and needs to meet specific usage requirements. Hardware sheets are an important part of hardware products, and their quality and performance directly affect the quality and performance of the final product. Moreover, in order to accurately manufacture hardware products, the angle of the sheet after cutting is also an important part of the inspection, otherwise it is easy to misalign during assembly, affecting the quality of the entire hardware product.
[0003] However, after the sheet is cut, a protractor is needed to measure its angle. After one end of the protractor currently used is fixed to one side of the sheet, the other end needs to be rotated and fitted to the other side. The angle displayed at this time is the angle of the sheet. However, since the two sides of the protractor intersect exactly at the calibration position of the sharp corner of the sheet, this position needs to realize the rotation of the two sides of the protractor, and is usually connected with a movable rod for easy rotation. At this time, the movable rod itself only has a certain width, which will affect the position of the sharp corner of the sheet that cannot be calibrated to the center point. The measured accuracy is insufficient and errors are prone to occur, which will ultimately affect the measurement results. Utility Model Content
[0004] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a sheet angle measurement tool, which can effectively solve the current technical problems of low accuracy and errors in sheet angle measurement.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A sheet material angle measuring tool comprises a base, wherein the surface of the base is provided with two arc frames fixed coaxially front and back, the edges of the arc frames are provided with hollow arc holes, a swing rod that can swing to both sides is inserted in the center of the base, the other end of the swing rod is arranged between the two arc frames and extends upward, both sides of the swing rod are connected with protrusions that slide on the outside of the arc holes, and the front end of the base is provided with an angle measuring plate that is simultaneously fitted with the arc frames, the angle measuring plate can move to the left and right sides, and the center of the angle measuring plate is aligned with the upper surface of the base.
[0007] Furthermore, the middle of the arc-shaped frame is hollowed out to reveal the position where the swing rod moves.
[0008] Furthermore, an arc-shaped groove which is connected to the arc-shaped hole and is used for placing a clamp is also provided at the edge of the arc-shaped frame.
[0009] Furthermore, the swing rod swings closely against the inner sides of the two arc-shaped frames.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figure 1-4 As shown, the utility model provides a sheet angle measuring tool, which is mainly used to measure the angle size of the sheet after cutting, or to detect the angle size problem of the sheet itself. Its structure mainly includes a base 1, and two arc frames 2 are coaxially fixed front and back on the surface of the base 1. A space for placing the sheet to be measured is formed between the two arc frames 2. When inserting the sheet, it is generally inserted from the right side, because the side exceeding 0 degrees for measuring the angle is set on the right side, so it is more convenient to measure. When the user puts in the sheet, the angle of the sheet to be measured is extended until it is at the center of the base 1.
[0023] A swing rod 4 that can swing to both sides is inserted at the center of the base 1, and the other end of the swing rod 4 is arranged between the two arc frames 2 and extends upward. After the swing rod 4 swings left and right, it forms a certain angle with the right side of the surface of the base 1, and forms a clamping point on the surface of the base 1 at the intersection. After the user puts in the pointed end of the sheet, one side of the sheet is attached to the surface of the base 1 when putting it in. The user swings the swing rod 4 so that the swing rod 4 fits with the other side of the sheet. At this time, the pointed corner of the sheet just falls to the position of the clamping point, that is, the angle to which the swing rod 4 falls is the angle of the sheet.
[0024] The interior of the arc frame 2 is hollowed out to display the position of the swing rod 4, and a hollow arc hole 3 is provided at the edge. Both sides of the swing rod 4 are connected with a clamping head 5 with a protrusion that is stuck on the outside of the arc hole 3 and slides. In order to prevent the swing rod 4 from shaking when swinging, the swing rod 4 swings close to the inside of the two arc frames 2, and additional clamping heads 5 extending to the outside of the arc hole 3 are provided on both sides of the rocker 4 to fit and move. In order to limit the moving profile of the clamping head 5, an arc groove 7 that is connected to the arc hole 3 and distributed around the arc hole 3 is added at the edge of the arc frame 2. When moving, the clamping head 5 is set in the arc groove 7 and moves. After the clamping head 5 moves in the arc groove 7, it is not easy to slide. At this time, the user can take out the sheet and measure the corresponding angle result by the position of the swing rod 4. There is no need to keep the sheet in place, which is inconvenient to operate.
[0025] One end of the swing rod 4 inserted into the base 1 is connected to a ring body 8, and a movable rod 9 inserted into the inside of the base 1 is inserted in the middle of the ring body 8. After the swing rod 4 is inserted into the base 1, the ring body 8 at the end swings left and right with the movable rod 9 as the base point, and as the swing rod 4 swings left and right, the ring body 8 always falls to the inside of the base 1 without protruding from the surface, so as to avoid affecting the insertion and alignment of the sheet. At the same time, in order to allow the swing rod 4 to move to a larger angle on both sides, a groove 10 is set at the position where the ring body 8 is assembled on the base 1, and the two sides of the groove 10 form inclined edges towards the two sides of the base 1, so that the swing rod 4 can adjust the angle conveniently.
[0026] An angle measuring plate 6 which is in contact with the arc frame 2 is provided at the front end of the base 1. The angle measuring plate 6 can move to the left and right sides and the center of the angle measuring plate 6 is aligned with the upper surface of the base 1. The angle measuring plate is a transparent plate structure with corresponding angle data engraved on the surface. The starting line of the angle data of 0 degrees is aligned with the surface of the base 1. That is to say, no matter how the angle measuring plate 6 moves, the starting position of the test angle is based on the surface of the base 1 and moves to different positions according to the included angle. It is only necessary to move and adjust the position of the angle measuring plate 6 so that the center overlaps with the included angle.
[0027] One side of the angle measuring plate 6 assembled on the base 1 is provided with two horizontally distributed elongated grooves 11, and the back side of the angle measuring plate 6 is connected with two adjusting rods 12 which are inserted into the corresponding elongated grooves 11 and moveable. The ends of the adjusting rods 12 can also be provided with protrusions to prevent them from falling off. The elongated grooves 11 on both sides are arranged and aligned on the same horizontal line, so that the angle measuring plate 6 can only move on the left and right horizontal lines. The starting line of this measuring angle remains aligned with the surface of the base 1. Since the pendulum rod 4 and the base 1 form angles of different sizes, the clamping points of different angles will change their positions with the size of the angle. Therefore, it is necessary to adjust and check the position of the angle measuring plate 6 so that the center point of the angle measuring plate 6 overlaps with the position where the angle is formed by the pendulum rod 4 to ensure correct measurement.
[0028] Compared with the traditional technology, after the sheet is inserted, the position of the rocker arm 4 can be swung until it is close to the side of the angle to be measured of the sheet. At this time, the rocker arm 4 and the base 1 form an angle equal to the angle of the sheet to be measured. The user only needs to move the angle measuring plate 6 horizontally so that the center point position overlaps with the angle, and the size of the sheet angle can be obtained according to the position of the rocker arm 4 on the angle measuring plate 6, thereby improving the measurement accuracy. The whole operation is simple, and there is no need to keep the sheet placed to affect the operation, so it is highly practical.
