[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-2 As shown, a pipe bend angle measuring fixture includes a fixed platform 1 and an angle measuring component. A support is vertically provided on the fixed platform 1. The angle measuring component is located above the fixed platform 1. The angle measuring component includes a fixed part, a movable part, and a measuring part. The fixed part is connected to the support part. The two ends of the movable part are rotatably connected to the fixed part and the measuring part, respectively. A protractor and a level 6 are provided on the measuring part.

[0017] It is understandable that when the pipe is placed on the fixed platform 1, with one end of the bend positioned below the measuring unit, the measuring unit will change from a horizontal state to an inclined state under the lifting force of one end of the bend, thereby allowing the measurement of the bend angle or verification of whether the bend angle is accurate.

[0018] Furthermore, the fixed part is a portal frame 4 with its opening facing downwards. The horizontal rods of the portal frame 4 are perpendicular to and connected to the support part. The movable part consists of two movable arms 5, one end of which rotates freely with the two vertical rods of the portal frame 4, and the other end is rotatably connected to the measuring part. In this embodiment, both ends of the movable arms 5 are connected to the angle measuring plate 7 and the portal frame 4 via annular hinge bolts 8.

[0019] The support includes an adjusting rod 2, on which a slider 3 is sleeved. The slider 3 is movably connected to the adjusting rod 2 via an annular hinge bolt 8. The middle part of the transverse rod of the portal bracket 4 is fixedly connected to the slider 3.

[0020] In this embodiment, both the gantry bracket 4 and the movable arm 5 are made of flat iron with a thickness of 3mm, a width of 20mm, and a length of 200mm. The flat iron of the gantry bracket 4 in the horizontal direction is welded and fixed to the slider 3 in the center. The two flat iron movable arms 5 at the end are connected to the gantry bracket 4 with ring-shaped hinge bolts 8. At the same time, the end of the movable arm 5 is fixed to the measuring platform with ring-shaped hinge bolts 8, which makes it easy to adjust the angle at will during measurement.

[0021] The adjusting rod 2 is a Φ20*800mm long stainless steel sliding rod, and the slider 3 consists of a Φ22 slider 3 and an M10 ring-shaped hinge bolt 8. The height of the slider 3 is adjusted to measure elbows of different diameters.

[0022] Furthermore, the measuring unit includes an angle measuring plate 7, and the two movable arms 5 are rotatably connected to the angle measuring plate 7 on both sides of the horizontal bar of the portal frame 4. The protractor and the level 6 are fixed on the upper surface of the angle measuring plate 7.

[0023] The angle measuring plate 7 is made of a steel plate with a thickness of 3mm, a width of 200mm, and a length of 280mm. The protractor and level 6 are used to accurately measure the corresponding angle values.

[0024] Furthermore, the fixed platform 1 is a portal frame with a slot 11 on its upper platform plate. The length direction of the slot 11 is perpendicular to the transverse bar of the portal bracket 4, and the pipe flange is connected to the slot 11 by bolts. The slot 11 is used to fix the pipe flange and prevent it from shifting during manufacturing.

[0025] When measuring a batch of 45° stainless steel elbows, first adjust the included angle on the movable arm 5, and then use a protractor and level 6 to determine the angle at 45°. Then tighten the annular hinge bolt 8 at the connection between the movable arm 5 and the angle measuring plate 7. In this way, when measuring the 45° elbow, simply push the 45° elbow onto the angle platform to quickly check the angle of the elbow.

[0026] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
