[0002] An ultrasonic non-destructive testing instrument is a portable industrial non-destructive testing instrument, mainly used to detect cracks and small holes on the surface of workpieces.

[0003] A search revealed that a digital ultrasonic flaw detector with a positioning device is disclosed in publication number "CN221745951U," relating to the field of ultrasonic flaw detection technology. The device includes an ultrasonic flaw detector body and a housing; symmetrical sliding grooves are provided on both sides of the ultrasonic flaw detector body. By configuring the ultrasonic flaw detector body and housing, which can slide and rotate relative to each other, the ultrasonic flaw detector body can be supported and positioned at different angles according to usage requirements.

[0004] The aforementioned flaw detector is mainly supported by the cooperation of a support plate and a support groove.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-5 An ultrasonic flaw detector with a positioning device is shown, including an ultrasonic flaw detector body 1. A U-shaped groove 2 is provided at the bottom edge of the back of the ultrasonic flaw detector body 1. A rotating shaft 4 is rotatably connected to both sides of the U-shaped groove 2. A U-shaped support frame 3 with a size adapted to the U-shaped groove 2 is rotatably connected between the two rotating shafts 4. The end of the U-shaped support frame 3 is designed with an arc. An auxiliary support structure is provided between the U-shaped support frame 3 and the U-shaped groove 2.

[0022] Specifically, the U-shaped support frame 3, which is rotatably connected inside the U-shaped groove 2, can position and support the ultrasonic flaw detector body 1 when it is in use. With the assistance of the auxiliary support structure, the stability of the ultrasonic flaw detector body 1 is improved. When not in use, the U-shaped support frame 3 can be stored and fixed inside the U-shaped groove 2, reducing the space occupied by the U-shaped support frame 3.

[0023] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses an ultrasonic flaw detector with a positioning device. The auxiliary support structure includes a U-shaped support frame 3 with strip grooves 12 on both sides of the back side, and a circular groove 13 at the end of each of the two strip grooves 12. An auxiliary rod 15 is rotatably connected to the other end of each of the two strip grooves 12.

[0024] A ball 17 is fixed at the end of the auxiliary rod 15. Multiple arc-shaped slots 14 are opened at equal intervals from top to bottom on both sides of the inner wall of the U-shaped groove 2. The ball 17 engages with the corresponding arc-shaped slot 14.

[0025] A groove 16 is provided at the center of one side of the auxiliary rod 15, and the inner wall of the groove 16 is provided with evenly distributed anti-slip texture.

[0026] Specifically, the ball 17 at the end of the auxiliary rod 15 abuts against the corresponding arc-shaped slot 14 to fix it, thereby forming a triangular shape between the ultrasonic flaw detector body 1, the U-shaped support frame 3 and the auxiliary rod 15, which improves the stability of the ultrasonic flaw detector body 1 in positioning.

[0027] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses an ultrasonic flaw detector with a positioning device. A groove 9 is provided at the center of the bottom of the U-shaped support frame 3. An inverted T-shaped positioning post 8 is nested inside the groove 9. A reset spring 10 is fixedly installed at the bottom of the groove 9. The top of the reset spring 10 is fixedly connected to the bottom of the inverted T-shaped positioning post 8. A positioning hole 7 is provided at the bottom of the U-shaped groove 2. The top of the inverted T-shaped positioning post 8 is nested and connected to the positioning hole 7.

[0028] The bottom dimension of the groove 9 is adapted to the bottom dimension of the inverted T-shaped positioning post 8, and the top dimension of the groove 9 is adapted to the top dimension of the inverted T-shaped positioning post 8.

[0029] The side wall of the groove 9 is provided with a through groove 5 that communicates with the outside. A slider 6 is slidably connected inside the through groove 5. A connecting block 11 is fixedly provided at the position where the inverted T-shaped positioning post 8 is aligned with the through groove 5. The connecting block 11 is fixedly connected to the bottom end of the slider 6.

[0030] Specifically, the extension and retraction of the inverted T-shaped positioning post 8 is controlled by the sliding block 6 inside the through groove 5 and the return spring 10 inside the groove 9, so that the inverted T-shaped positioning post 8 can be nested and separated from the positioning hole 7. When not in use, the U-shaped support frame 3 can be rotated into the U-shaped groove 2, and the U-shaped support frame 3 can be fixed inside the U-shaped groove 2 by the nesting of the inverted T-shaped positioning post 8 and the positioning hole 7, thus reducing the space occupied.

[0031] The working principle of this utility model is as follows: When using the ultrasonic flaw detector, firstly, the slider 6 is manually pushed, which drives the inverted T-shaped positioning post 8 to move, so that the top of the inverted T-shaped positioning post 8 separates from the positioning hole 7. Then, the U-shaped support frame 3 is manually rotated so that a certain angle is formed between the U-shaped support frame 3 and the ultrasonic flaw detector body 1, which can support the ultrasonic flaw detector body 1. It should be noted that the angle is not fixed, as long as the U-shaped support frame 3 can support the ultrasonic flaw detector body 1. Next, the two auxiliary rods 15 are manually rotated out of the strip groove 12 through the pull groove 16, and the ball 17 at the end of the auxiliary rod 15 is embedded in the arc-shaped slot 14 opened on the side wall of the corresponding U-shaped groove 2, so that the ultrasonic flaw detector body 1, the U-shaped support frame 3 and the auxiliary rods 15 form a triangular shape, ensuring the stability of the ultrasonic flaw detector body 1 in support and positioning.
