Description

Technical Field

[0001] This utility model relates to the field of pipeline testing technology, specifically a measuring device for testing right-angle bends in pipes. Background Technology

[0002] A right-angle bend is a pipe fitting used to change the direction of a pipeline. Its angle is 90 degrees, and it is also called a 90-degree elbow. Right-angle bends play an important role in pipeline systems, enabling pipelines to turn within a 90-degree angle, thereby achieving flexible pipeline layout and connection.

[0003] Right-angle bends are widely used in piping systems, and their machining accuracy directly affects the assembly result. Existing technologies have the following problems:

[0004] Low detection efficiency: Traditional methods rely on manual measurement using angle rulers and other methods in steps, resulting in large errors;

[0005] Limited functionality: Existing devices only support the detection of a single parameter (such as angle) and cannot simultaneously measure radius parameters;

[0006] Poor adaptability: Fixed fixtures are difficult to adapt to bends with different pipe diameters or bending radii. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for detecting right-angle bends, comprising a base, a ruler fixedly connected to the inner side of the base, and an adjustment mechanism provided at the bottom of the base;

[0009] The adjustment mechanism includes a slide rail, which is fixedly connected to the bottom of the base. A sliding plate is fixedly connected to the inner wall of the slide rail. A nut is fixedly connected to the bottom of the sliding plate. A locking bolt is threaded inside the nut. A connecting pipe is fixedly connected to the top of the locking bolt. A round tube is provided on the outer wall of the connecting pipe. An arc-shaped fixing baffle is fixedly connected to the outer wall of the round tube.

[0010] Preferably, the top of the base has a slot, through which the locking bolt passes, allowing the locking bolt to move.

[0011] Preferably, the slide has a circular hole inside, and the locking bolt passes through the circular hole, allowing the locking bolt to move through the circular hole.

[0012] Preferably, a handle is fixedly connected to the outer wall of the connecting pipe, so that the connecting pipe can be rotated by the handle.

[0013] Preferably, the bottom of the arc-shaped fixed baffle has a movable opening, through which the ruler passes, allowing the arc-shaped fixed baffle to be moved by the ruler.

[0014] Preferably, the inner wall shape of the circular tube matches the outer wall shape of the connecting tube, and the connecting tube is slidably connected to the inner wall of the circular tube, so that the connecting tube can move and be limited inside the circular tube.

[0015] Compared with the prior art, this utility model provides a measuring device for detecting right-angle bends in pipes, which has the following advantages:

[0016] 1. This measuring device for detecting right-angle bends can simultaneously detect angle and radius through an adjustable mechanism; it also has a large radius detection range and good adaptability. Attached Figure Description

[0022] This utility model provides the following technical solution:

[0023] Combination Figures 1 to 4 A measuring device for detecting right-angle bends includes a base 1, a ruler 2 fixedly connected to the inner side of the base 1, and an adjustment mechanism 3 provided at the bottom of the base 1.

[0024] The adjustment mechanism 3 includes a slide 31, which is fixedly connected to the bottom of the base 1. A slide plate 32 is fixedly connected to the inner wall of the slide 31. A nut 33 is fixedly connected to the bottom of the slide plate 32. A locking bolt 34 is threaded inside the nut 33. A connecting pipe 35 is fixedly connected to the top of the locking bolt 34. A round pipe 36 is provided on the outer wall of the connecting pipe 35. An arc-shaped fixing baffle 37 is fixedly connected to the outer wall of the round pipe 36.

[0025] The top of the base 1 has a slot, through which the locking bolt 34 passes, allowing the locking bolt 34 to move.

[0026] The slider 32 has a circular hole inside, through which the locking bolt 34 passes, allowing the locking bolt 34 to move.

[0027] A handle is fixedly connected to the outer wall of the connecting pipe 35, which makes it easy to rotate the connecting pipe 35 by using the handle.

[0028] The bottom of the arc-shaped fixed baffle 37 has a movable opening, through which the ruler 2 passes, allowing the arc-shaped fixed baffle 37 to be moved by the ruler 2.

[0029] The inner wall shape of the circular tube 36 matches the outer wall shape of the connecting tube 35. The connecting tube 35 is slidably connected to the inner wall of the circular tube 36, so that the connecting tube 35 can move and be limited inside the circular tube 36.

[0030] In actual operation, when this device is used, rotating the connecting pipe 35 causes the locking bolt 34 to rotate. Since the nut 33 and the locking bolt 34 are threaded, the connecting pipe 35 will move upward, so that the connecting pipe 35 does not press the base 1. At this time, the arc-shaped fixed baffle 37 can be pushed to move, so that it can be measured according to the right-angle bends of different diameters. Similarly, the purpose of locking and positioning the arc-shaped fixed baffle 37 can also be achieved.
