When the description refers to the drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements. The contents described in the following exemplary embodiments do not represent all embodiments consistent with the present invention; on the contrary, they are merely examples of devices, products and / or methods that are consistent with some aspects of the present invention and are recorded in the claims of the present invention.

[0053] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the scope of protection of the present invention. The singular forms "a", "said" or "the" used in the specification and claims of the present invention are also intended to include plural forms, unless the context clearly indicates other meanings.

[0054] Please refer to Figures 1 to 14 The utility model discloses an angle measuring instrument 100, which includes a first support rod 1, a second support rod 2, a swing rod 3 and a scale 4. The first support rod 1 and the second support rod 2 are hinged to each other, and the first support rod 1 and the second support rod 2 are used to abut against the object to be measured 10. The scale 4 includes a first section 41 and a second section 42, one end of the first section 41 is connected to the first support rod 1, one end of the second section 42 is connected to the second support rod 2, and the other end of the first section 41 is pivotally connected to the other end of the second section 42 so that the first section 41 and the second section 42 are straightened or bent. The swing rod 3, the first support rod 1, and the second support rod 2 are hinged to each other, and the swing rod 3 swings between the first support rod 1 and the second support rod 2, the swing rod 3 and the scale 4 are cross-arranged, and the swing rod 3 extends toward the scale 4 to indicate the angle of the object to be measured 10. In this way, the angle measuring instrument 100 has the advantages of simple measurement and convenient carrying.

[0055] Please refer to Figure 1 For convenience, we define Figure 1 The first direction D1-D1 shown is a height direction, the second direction D2-D2 is a left-right direction, and the third direction D3-D3 is a front-back direction. The first direction D1-D1, the second direction D2-D2, and the third direction D3-D3 are perpendicular to each other.

[0056] Please refer to Figures 1 to 7 The first support rod 1 includes a first body portion 11 and a first rotating portion 12 provided at one end of the first body portion 11, the second support rod 2 includes a second body portion 21 and a second rotating portion 22 provided at one end of the second body portion 21, and the swing rod 3 includes a third body portion 31 and a third rotating portion 32 provided at one end of the third body portion 31. The first rotating portion 12, the second rotating portion 22 and the third rotating portion 32 are hinged to each other through a hinge. When the other end of the first body portion 11 and the other end of the second body portion 21 are separated from each other, the first sub-portion 41 and the second sub-portion 42 are straightened, and the angle measuring instrument 100 is fully unfolded to measure the angle of the object to be measured 10. When the other end of the first body portion 11 and the other end of the second body portion 21 are close to each other, the first sub-portion 41 and the second sub-portion 42 are bent, so that the angle measuring instrument 100 can be recovered for easy carrying.

[0057] Please refer to Figure 3 In this embodiment, after the angle measuring instrument 100 is fully unfolded, the first support part 1, the second support part 2 and the scale 4 form a triangular structure. After the angle measuring instrument 100 is fully unfolded, it is placed on a horizontal plane. By setting the first support rod 1 and the second support rod 2 to have the same length, and the first subdivision 41 and the second subdivision 42 to have the same length, the pendulum 3 is vertically downward due to its own gravity, and the extension direction of the pendulum 3 overlaps with the perpendicular bisector of the angle measuring instrument 100. At this time, the first subdivision 41 and the second subdivision 42 can be symmetrically arranged along the perpendicular bisector of the angle measuring instrument 100. In this way, the angle measuring instrument 100 does not need to consider the angular direction of the object to be measured 10, and can accurately and quickly measure the angle of the object to be measured 10 through the first subdivision 41 and the second subdivision 42. Preferably, the pendulum 3 is made of polymer material, so that the weight of the pendulum 3 is large, and the pendulum 3 can quickly swing to a free hanging position, thereby improving the efficiency and accuracy of the measurement.

[0058] In this embodiment, the measuring method of the angle measuring instrument 100 is as follows: the angle measuring instrument 100 is fully unfolded and placed on the object to be measured 10, the first section 41 and the second section 42 are in a stretched state, and the pendulum 3 is vertically downward due to its own gravity. According to the geometric relationship, the angle a between the pendulum 3 and the normal line cc of the surface of the object to be measured 10 is the angle b of the object to be measured 10. The angle a can be directly obtained by the scale value of the scale 4 indicated by the pendulum 3. Therefore, the measuring method of the angle measuring instrument 100 of the present application is simple and fast.

[0059] Please refer to Figures 1 to 4The first support rod 1 further includes a first abutting portion 13 disposed at the other end of the first body portion 11, and the second support rod 2 further includes a second abutting portion 23 disposed at the other end of the second body portion 21. In the first embodiment, the free ends of the first abutting portion 13 and the second abutting portion 23 are in a bee stylus shape, so that the first abutting portion 13 and the second abutting portion 23 can be stably and flexibly overlapped on the surface of the object to be measured 10, thereby preventing the angle measuring instrument 100 from shaking and causing measurement errors.

[0060] Please refer to Figure 4 , the first main body 11 is a columnar structure. Specifically, the outer wall of the first main body 11 includes a first vertical wall 111 and a first curved wall 112, and the first vertical wall 111 is arranged facing the second support rod 2. The outer wall of the first abutment portion 13 includes a second vertical wall 131 and a second curved wall 132, and the second vertical wall 131 is arranged on one side facing the second support rod 2, and the second vertical wall 131 and the first vertical wall 111 are in the same plane, and the second curved wall 132 extends downward from the edge of the first curved wall 112 and gradually becomes smaller, so that the free end of the first abutment portion 13 is in the shape of a bee sting. By grinding the first abutment portion 13 into a sharp bee sting shape, the first abutment portion 13 can be stably and flexibly overlapped on the surface of the object to be measured 10 to avoid shaking and causing errors. At the same time, the first main body 11 is polished as a whole, which is not only beautiful but also prevents the measuring personnel from scratching their fingers during use. Preferably, the structure of the second body portion 21 is consistent with that of the first body portion 11, and the structure of the second abutting portion 23 is consistent with that of the first abutting portion 13, which will not be described in detail. In other embodiments, the structure of the second body portion 21 may be different from that of the first body portion 11.

[0061] The structure of the second abutting portion 23 may be different from that of the first abutting portion 13. Specifically, the first abutting portion 13 is in the shape of a bee sting, and the shape of the second abutting portion 23 is not limited. Alternatively, the second abutting portion 23 is in the shape of a bee sting, and the shape of the first abutting portion 13 is not limited. In this way, it can also be ensured that the first abutting portion 13 or the second abutting portion 23 can be stably and flexibly overlapped on the surface of the object to be measured 10, so as to measure the angle of the object to be measured 10.

[0062] Please refer to Figure 5In the embodiment of the present application, the first rotating portion 12 includes two first clamping portions 121 parallel to each other, and the two first clamping portions 121 are provided with a first concentric hole 101. The second rotating portion 22 includes two second clamping portions 221 parallel to each other, and the two second clamping portions 221 are provided with a second concentric hole 201. The swing arm 3 includes a third clamping portion, and the third clamping portion is provided with a through hole 301. The first concentric hole 101, the second concentric hole 201 and the through hole 301 are concentrically arranged, and the hinge axis 6 of the hinge passes through the first concentric hole 101, the second concentric hole 201 and the through hole 301, so that the two first clamping portions 121, the two second clamping portions 221 and the third clamping portion can rotate around the hinge axis 6 at the same time, thereby driving the first abutting portion 13 and the second abutting portion 23 to be relatively close to or separated, and the third main body portion 31 swings between the first main body portion 11 and the second main body portion 21. Preferably, the two first clamping portions 121 and the two second clamping portions 221 are both located on both axial sides of the third clamping portion, so as to improve the overall structural strength of the first rotating portion 12 , the second rotating portion 22 and the third rotating portion 32 .

[0063] Please refer to Figures 5 to 7 Preferably, a first arc-shaped portion 113 is provided at one end of the first body portion 11, and two first clamping portions 121 are provided on the arc surface of the first arc-shaped portion 113. The arc surface of the first arc-shaped portion 113 is arranged toward the second clamping portion 221, and the arc surface of the first arc-shaped portion 113 matches the second peripheral wall 2211 of the second clamping portion 221. A second arc-shaped portion 211 is provided at one end of the second body portion 21, and two second clamping portions 221 are provided on the surface of the second arc-shaped portion 211, and the arc surface of the second arc-shaped portion 211 faces the first clamping portion 121, and the arc surface of the second arc-shaped portion 211 matches the first peripheral wall 1211 of the first clamping portion 121. In this way, when the first clamping portion 121 and the second clamping portion 221 are assembled through the hinge shaft 6, the first clamping portion 121 and the second clamping portion 221 are smoother in the process of rotating with each other, and are less likely to get stuck.

[0064] In the second embodiment, the first rotating part 12 further includes a first gear, the second rotating part 22 further includes a second gear, and the first gear meshes with the second gear. In this way, the first support rod 1 and the second support rod 2 can also be hinged to each other.

[0065] In the third embodiment, the first rotating part 12 is a first clamping part 121, the second rotating part 22 is a second clamping part 221, the third rotating part 32 is a third clamping part, and the hinge shaft 6 passes through a first concentric hole 101, a second concentric hole 201 and a through hole 301, so that the rocker arm 3, the first support rod 1 and the second support rod 2 are hinged to each other, and the three can rotate around the hinge shaft 6.

[0066] Please refer to Figure 1 , Figure 3 , the pendulum 3 is arranged to cross the scale lines on the scale 4. Specifically, when the first support rod 1 and the second support rod 2 are fully unfolded, the first subdivision 41 and the second subdivision 42 of the scale 4 are in a straightened state, at this time, the scale lines on the first subdivision 41 and the second subdivision 42 are symmetrically distributed along the second direction D2-D2, and the pendulum 3 extends along the first direction D1-D1, so that the pendulum 3 and the scale 4 are in a cross state, which facilitates the measurement personnel to quickly read the scale value on the scale 4 through the pendulum 3, thereby improving the measurement efficiency.

[0067] Please refer to Figures 8 to 9 The pendulum 3 has a scale hole 302 along its length direction. Specifically, the scale hole 302 is located on the third body portion 31, and the scale hole 302 extends along the length direction of the pendulum 3. In this embodiment, the scale hole 302 is higher than the scale 4 in the first direction D1-D1. When the pendulum 3 hangs freely due to its own gravity, the scale line on the scale 4 is located in the scale hole 302, and the measurement personnel can directly read the scale value corresponding to the scale line through the scale hole 302. The read scale value is the angle of the object 10 to be measured, thereby improving the measurement accuracy and convenience of the angle measuring instrument 100.

[0068] Please refer to Figures 1 to 3 as well as Figure 10 to Figure 11 , the scale 4 also includes a movable lock 5, and the first division 41 and the second division 42 are pivotally connected to the movable lock 5.

When the first support rod 1 and the second support rod 2 are fully unfolded, the first division 41 and the second division 42 are straightened, and the second end 412 and the fourth end 422 are in contact with the movable lock 5. At this time, the movable lock 5 can lock the first division 41 and the second division 42. By locking the first division 41 and the second division 42, the first support rod 1 and the second support rod 2 remain fixed, thereby improving the accuracy of measurement. After the angle measuring instrument 100 completes the measurement, the movable lock buckle 5 is pulled upward, and the movable lock buckle 5 drives the first sub-section 41 and the second sub-section 42 to rotate from a straight state to a bent state, thereby driving the first support rod 1 and the second support rod 2 to be recovered for easy carrying.

[0069] The first sub-section 41 and the second sub-section 42 are symmetrical with respect to the movable lock buckle 5, and the first sub-section 41 and the second sub-section 42 are respectively arranged on both sides of the movable lock buckle 5. In this way, the scale values ​​of the first sub-section 41 and the second sub-section 42 are consistent. Preferably, the scale values ​​are arranged on the outer wall surfaces of the first sub-section 41, the movable lock buckle 5 and the second sub-section 42. When the first sub-section 41, the movable lock buckle 5 and the second sub-section 42 are in a straight line in the second direction D2-D2, with the movable lock buckle 5 as the center, the scale values ​​gradually increase to both sides, so as to facilitate the measurement personnel to quickly read the scale values ​​and improve the measurement efficiency.

[0070] Please refer to Figures 10 to 14 The movable lock buckle 5 includes a connecting portion 51 and a bending portion 52 disposed on one side of the connecting portion 51. The first sub-portion 41 and the second sub-portion 42 are connected to the connecting portion 51 through a connecting member 53, and the bending portion 52 abuts against the first sub-portion 41 and the second sub-portion 42.

The connecting portion 51 includes a front wall 511 and a rear wall 512 disposed opposite to each other in the third direction D3-D3. The first sub-portion 41, the second sub-portion 42 and the front wall 511 are provided with scale values, and the bending portion 52 is disposed on the rear wall 512. The connecting member 53 includes a first connecting portion 531 and a second connecting portion 532. The first connecting portion 531 and the second connecting portion 532 are arranged on the rear wall 512 and protrude along the third direction D3-D3. The first connecting portion 531 and the second connecting portion 532 are arranged at intervals in the second direction D2-D2, and the first connecting portion 531 and the second connecting portion 532 are symmetrical on the connecting portion 51. The second end 412 has a first positioning hole 401, and the fourth end 422 has a second positioning hole 402. The first positioning hole 401 is sleeved on the first connecting portion 531 and pivots around the first connecting portion 531, and the second positioning hole 402 is sleeved on the second connecting portion 532 and pivots around the second connecting portion 532. When the first sub-portion 41, the movable lock buckle 5 and the second sub-portion 42 are in a straightened state, the bending portion 52 abuts against the first sub-portion 41 and the second sub-portion 42, thereby avoiding the first support rod 1 or the second support rod 2 moving during the measurement process to cause reading errors, thereby improving the accuracy of the measurement. When the measurement is completed and the angle measuring instrument 100 needs to be recovered, the movable lock buckle 5 is pulled up, and the second end 412 and the fourth end 422 can be rotated on the side away from the bending portion 52, so that the first section 41 and the second section 42 are close to each other and in a bent state, thereby driving the first support rod 1 and the second support rod 2 to be recovered, making it easier to carry the angle measuring instrument 100.

[0071] Please refer to Figure 10 to Figure 11, a rounded corner is provided at one end opposite to the first sub-portion 41 and the second sub-portion 42. Specifically, the second end 412 and the fourth end 422 are provided with rounded corners, so that the second end 412 and the fourth end 422 can be embedded in the movable lock buckle 5 during the rotation process without being stuck.
