Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses universal angle ruler for engineering cost. Referring to fig. 1, the universal angle gauge includes a main angle gauge 1 and a measuring scale 2.

The main angle ruler 1 and the measuring ruler 2 can be made of stainless steel. The angle main scale 1 is semicircular, and a first angle scale 11 is arranged on the arc edge of the angle main scale 1. The first angle scale line 11 is typically located on an outer circle having a smaller radius than the radius of the main angle scale 1 so that the zero point of the first angle scale line 11 is not located at the intersection of the arc and straight sides of the main angle scale 1. Dipperstick 2 is the ruler form, dipperstick 2 butt in angle main scale 1's first angle scale 11 place one side, and dipperstick 2 is articulated with angle main scale 1 through locking piece 3. The locking piece 3 is located the centre of a circle department of the excircle at first angle scale line 11 place, and the pin joint of dipperstick 2 and angle main scale 1 is located the centre of a circle department of the excircle at first angle scale line 11 place promptly. The distance between one end of the measuring scale 2 and the locking piece 3 is larger than the radius of the excircle where the first angle scale line 11 is positioned, namely when one end of the measuring scale 2 rotates to one side where the arc edge of the main angle scale 1 is positioned, the end part extends out of the main angle scale 1; the other end of dipperstick 2 is located first angle scale 11, and when the other end of dipperstick 2 rotated to the one side at angle main scale 1 arc place promptly, this tip was located within angle main scale 1.

When carrying out the measurement of angle in the engineering cost, the user can loosen locking piece 3 earlier, then rotates dipperstick 2, can make the edge of dipperstick 2 and the straight flange of angle main scale 1 present different angles to dipperstick 2 is located the specific numerical value that the one end within angle main scale 1 can indicate out this angle, thereby reaches the purpose of measuring angle. The measuring process is simple to operate, the structure of the universal angle ruler is simple, the size and the mass are small, and therefore the measuring process is convenient and fast to carry out.

The middle part of the main angle ruler 1 is provided with a hollow part 12. The hollow 12 is used for further reducing the quality of the main angle ruler 1, so that the using process of the universal angle ruler is more convenient. The hollows 12 are arc-shaped, so that the damping effect can be optimal. And fretwork 12 can also make omnipotent angle chi can be hung on storage tools such as couple to make things convenient for taking of omnipotent angle chi.

And a second angle scale line 13 is arranged on the outer arc edge of the hollow part 12. The outer circle on which the second angle score line 13 is located is concentric with the outer circle on which the first angle score line 11 is located, i.e. the second angle score line 13 can also be used to measure angular readings. If the first angle score line 11 is used as a reading score line for measuring the outer angle, the second angle score line 13 can be used as a reading score line for measuring the inner angle. The second angle scale line 13 enables reading during measurement to be more convenient and fast, and working efficiency during measurement operation is improved.

An auxiliary measuring scale 4 parallel to the straight edge is arranged at one end of the straight edge of the angle main scale 1. The auxiliary measuring scale 4 and the angle main scale 1 are positioned on the same plane, and the auxiliary measuring scale 4 and the angle main scale 1 are of an integrated structure. The sum of the lengths of the straight sides of the auxiliary measuring tape 4 and the angle main 1 is equal to the length of the measuring tape 2. When measuring an angle, the auxiliary measuring scale 4 can extend the straight edge of the main angle scale 1, so that the straight edge of the main angle scale 1 is aligned more accurately with the side line of the measured angle, and the accuracy of the measuring result is improved. The auxiliary scale 4 may also be provided with score lines to enable the auxiliary scale 4 to be used to measure distance or length.

In order to improve the accuracy of the reading, the end of the measuring ruler 2 on the first angle scale 11 is provided with a pointer 21. The pointer part 21 is formed by notching the end of the measuring scale 2, and the pointer part 21 is provided with an indicating edge parallel to the edge of the measuring scale 2. The straight line of the indicating edge passes through the center of the excircle of the first angle scale line. When the indicating edge is aligned with the graduation marks on the first angle scale 11, the reading of the measured angle can be read more intuitively.

Referring to fig. 1 and 2, the indicating edge is provided with a cutting edge 211. The cutting edge 211 is formed by chamfering the indicating edge, and the cutting edge 211 is located on the side of the measuring ruler 2 far away from the main angle ruler 1. The cutting edge 211 not only makes the reading of the measured angle more directly perceived clear, and the cutting edge 211 can also be used as the blade, plays the effect of cutting apart paper, sticky tape etc. has strengthened the functional of omnipotent angle chi.

The measuring scale 2 is provided with a linear scale 22. The straight line scale 22 enables the measuring tape 2 to be used for distance or length measurements, thereby making the universal angle ruler more versatile and more convenient to measure. The straight line segment 22 has the end of the measuring scale 2 as a zero point, and the end is an end having a distance from the lock member 3 larger than the outer radius of the circle on which the first angle segment 11 is located, i.e., an end away from the indicating edge. The zero point at this end does not float during measurement and is therefore more easily aligned with the start of the measured distance or length.

Referring to fig. 1 and 3, the lock member 3 includes a rivet seat 31, a lock bolt 32, and a spring 33. The riveting seat 31 is embedded on one side of the angle main scale 1 far away from the measuring scale 2, and the riveting seat 31 is fixedly connected with the angle main scale 1. Locking bolt 32 wears to establish in proper order on dipperstick 2 and angle main scale 1, and locking bolt 32 and the 31 threaded connection of riveting seat to reach and rotate dipperstick 2 and set up the purpose on angle main scale 1. The fixed point of the locking bolt 32 is therefore the center of the outer circle of the first angle graduation line 11.

The spring 33 is sleeved on the locking bolt 32, one end of the spring 33 is abutted against the head of the locking bolt 32, and the other end of the spring 33 is abutted against the measuring scale 2. The spring 33 is used for prestressing the locking bolt 32, so that the locking bolt 32 is not easy to rotate randomly, and the locking effect of the locking bolt on the measuring scale 2 and the angle main scale 1 is better. An abutment pad 34 is provided between the spring 33 and the measuring scale 2. When the spring 33 is compressed, the spring 33 abuts against the abutment pad 34, so that the abutment pad 34 can reduce the wear of the spring 33 on the surface of the measuring scale 2.

One end of the locking bolt 32 in threaded connection with the rivet seat 31 is provided with a limiting part 321. The limiting portion 321 is tapered, and the limiting portion 321 and the locking bolt 32 are integrated. The large end of the limiting portion 321 is the end far away from the locking bolt 32, and the small end of the limiting portion 321 is the end close to the locking bolt 32. The rivet seat 31 is provided with an embedding groove 311 at one end far away from the measuring scale 2, and the limiting part 321 is positioned in the embedding groove 311. The stopper 321 prevents the lock bolt 32 from being separated from the rivet seat 31, thereby preventing the measuring scale 2 and the angle main scale 1 from being separated.

The implementation principle of the universal angle ruler for the engineering cost in the embodiment of the application is as follows: during manufacturing, the angle main ruler 1, the auxiliary measuring ruler 4 and the measuring ruler 2 are respectively machined and molded, and the angle main ruler 1 is provided with the hollow 12.
