[0024] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 - 5, the present utility model provides an ultrasonic flaw detector for steel structure detection, including an ultrasonic flaw detector body 1; a probe 11 is installed on the side wall of the ultrasonic flaw detector body 1; a screw rod 12 is rotatably connected to the side wall of the probe 11; a connecting block 13 is threadedly connected to the side wall of the screw rod 12; a plurality of support arms 14 are evenly hinged to the side wall of the connecting block 13; a plurality of first telescopic rods 15 are fixedly connected to the side wall of the probe 11; the first telescopic rods 15 are evenly distributed on the side wall of the probe 11 and have the same structure; an end portion of the first telescopic rod 15 is fixedly connected to a fixing plate 16; the support arm 14 and the fixing plate 16 are in a hinged relationship; a slot 17 is opened on the side wall of the fixing plate 16; a suction cup 18 is provided on the side wall of the slot 17; when in use, first hold the screw rod 12 and rotate it. As the screw rod 12 rotates, the connecting block 13 can perform a lifting movement. At this time, the support arm 14 can be pressed, and the surrounding fixing plates 16 can be pushed through the support arm 14, so that the first telescopic rod 15 performs a telescopic movement. When the surrounding fixing plates 16 are unfolded to an appropriate size, press the probe 11 against the surface of the steel structure, so that the suction cup 18 fits with the steel structure. The suction cup 18 can generate a certain suction force on the steel structure to fix the probe 11. In this process, through the adsorption effect generated by the suction cup 18 on the surface of the steel structure, the anti-sliding effect of the probe 11 during detection can be achieved, improving the stability of the probe 11. At the same time, by rotating the screw rod 12 to adjust the opening degree of the fixing plate 16, the contact and fitting effect on the surfaces of steel structures of different sizes can be achieved.

[0027] Further, as Figure 1 , Figure 2 , Figure 4 , Figure 5 shown, a fixing frame 2 is fixedly connected to the side wall of the probe 11; a first spring 21 is fixedly connected to the side wall of the fixing frame 2; a plug rod 22 is fixedly connected to the end portion of the first spring 21; a pull rod 23 is fixedly connected to the side wall of the plug rod 22; the pull rod 23 penetrates through the wall body of the fixing frame 2 and is slidably connected thereto; a slot 24 is opened on the side wall of the screw rod 12; when in use, hold and pull the pull rod 23. After the rotation adjustment of the screw rod 12 is completed, make the positions of the slot 24 and the plug rod 22 correspond, and then release the pull rod 23. At this time, through the elasticity of the first spring 21, the plug rod 22 can be pushed into the side wall of the slot 24 to make it stuck, so as to fix the screw rod 12. In this process, by inserting the plug rod 22 into the side wall of the slot 24, the anti-rotation effect of the screw rod 12 after use can be achieved, improving the fixing effect on the screw rod 12, and reducing the situation that when the screw rod 12 is accidentally pulled during the use of the probe 11, the screw rod 12 is likely to rotate, thereby affecting the fixing effect of the probe 11.

[0028] Further, as Figure 5As shown, a plurality of grooves 3 are evenly formed on the side wall of the insertion rod 22; a plurality of elastic pieces 31 are fixedly connected to the side wall of the insertion slot 24; the elastic pieces 31 are evenly distributed on the side wall of the insertion slot 24 and have the same structure; a rubber block 32 is fixedly connected to the side wall of the elastic piece 31; during use, when the insertion rod 22 is inserted into the side wall of the insertion slot 24, the insertion rod 22 will squeeze the elastic piece 31 and push it open. When the groove 3 corresponds to the position of the rubber block 32, the elastic force of the elastic piece 31 can make the rubber block 32 snap into the side wall of the groove 3. When the two are in full contact, a certain frictional force will be generated, thereby fixing the insertion rod 22. During this process, by snapping the rubber block 32 into the side wall of the groove 3, the anti-shaking effect of the insertion rod 22 on the side wall of the insertion slot 24 can be achieved, improving the fixing effect of the insertion rod 22 on the side wall of the insertion slot 24, and reducing the repeated shaking of the insertion rod 22 on the side wall of the insertion slot 24 caused by the elastic action of the first spring 21.

[0029] Further, as Figure 2 、 Figure 3 shown, a jack 4 is formed on the side wall of the fixing plate 16; a fixing rod 41 is slidably connected to the side wall of the jack 4; a clamping groove 42 is formed on the side wall of the fixing rod 41; a clamping block 43 is hinged to the side wall of the fixing plate 16; during use, by holding the suction cup 18 and placing the suction cup 18 in the grooved slot 17, the fixing rod 41 passes through the jack 4. At this time, the fixing rod 41 can push the clamping block 43 open. When the clamping block 43 corresponds to the position of the clamping groove 42, it can automatically reset under the action of the torsion spring inside the hinge of the clamping block 43, so that it snaps into the side wall of the clamping groove 42 to fix the suction cup 18. During this process, through the arranged clamping block 43, the function of facilitating the disassembly and installation of the suction cup 18 can be achieved, improving the convenience during the disassembly and maintenance of the suction cup 18, and reducing the inconvenience in disassembling the suction cup 18 when it is damaged, resulting in an increase in the workload.

[0030] Further, as Figure 3 shown, a second telescopic rod 5 is fixedly connected to the side wall of the suction cup 18; a second spring 51 is sleeved outside the second telescopic rod 5; the second telescopic rod 5 and the second spring 51 are fixedly connected to the fixing rod 41; during use, when the suction cup 18 is pressed onto the steel structure surface, at the same time, a certain thrust can be applied to the suction cup 18 under the elasticity of the second spring 51, so that the suction cup 18 can be fully attached to the steel structure surface. During this process, through the elasticity of the second spring 51, the full attachment effect between the suction cup 18 and the steel structure surface can be increased, improving the adsorption effect of the suction cup 18 on the steel structure, and reducing the poor fitting effect between the suction cup 18 and the steel structure, thereby affecting the fixing effect of the probe 11.

[0031] Further, as Figure 3As shown, a buckle plate 6 is fixedly connected to the side wall of the clamping block 43; the buckle plate 6 is arc-shaped; during use, by hooking the finger on the buckle plate 6, under the action of the arc of the buckle plate 6, the finger can be reversely hooked, and then pulled, and the clamping block 43 can be pulled open. In this process, through the arranged buckle plate 6, the convenience of pulling open the clamping block 43 can be achieved, the firmness of the finger on the side wall of the clamping block 43 can be improved, and the inconvenience of holding the clamping block 43, which causes it to easily slip off the side wall during pulling, can be reduced.

[0032] Furthermore, as Figure 3 shown, a plurality of limiting plates 7 are evenly and fixedly connected to the side wall of the slot 17; during use, when the fixing rod 41 is inserted into the side wall of the insertion hole 4, under the action of the limiting plates 7, the fixing rod 41 can slide towards the middle of the surrounding limiting plates 7. In this process, through the arranged limiting plates 7, the limiting effect of inserting the fixing rod 41 into the side wall of the insertion hole 4 can be achieved, the convenience of insertion can be improved, and the difficulty of aligning the two, which causes the insertion process to be more cumbersome, can be reduced.

[0033] Working principle: When in use, first hold the screw rod 12 and rotate it. As the screw rod 12 rotates, the connecting block 13 can perform a lifting motion. At this time, the support arm 14 can be pressed, and through the support arm 14, the fixed plates 16 around can be pushed, causing the first telescopic rod 15 to perform a telescopic motion. When the fixed plates 16 around are unfolded to an appropriate size, press the probe 11 onto the steel structure surface so that the suction cup 18 fits with the steel structure. Through the suction cup 18, a certain suction force can be generated on the steel structure to fix the probe 11. When in use, hold and pull the pull rod 23. After the rotation adjustment of the screw rod 12 is completed, make the positions of the slot 24 and the plug rod 22 correspond, and then release the pull rod 23. At this time, through the elasticity of the first spring 21, the plug rod 22 can be pushed into the side wall of the slot 24 to make it stuck and fix the screw rod 12. When in use, during the process of inserting the plug rod 22 into the side wall of the slot 24, the plug rod 22 will squeeze the elastic piece 31 and push it open. When the groove 3 and the rubber block 32 are in corresponding positions, through the elasticity of the elastic piece 31, the rubber block 32 can be stuck into the side wall of the groove 3, and a certain frictional force will be generated when the two are in full contact, thereby fixing the plug rod 22. When in use, hold the suction cup 18 and place the suction cup 18 in the slot 17, so that the fixing rod 41 passes through the jack 4. At this time, the fixing rod 41 can push the clamping block 43 open. When the clamping block 43 and the clamping groove 42 are in corresponding positions, under the action of the torsion spring inside the hinge of the clamping block 43, it can automatically reset and be stuck into the side wall of the clamping groove 42 to fix the suction cup 18. When in use, when the suction cup 18 is pressed onto the steel structure surface, at the same time, under the elasticity of the second spring 51, a certain thrust can be applied to the suction cup 18 to make the suction cup 18 fully fit with the steel structure surface. When in use, hook the finger on the buckle plate 6. Under the arc action of the buckle plate 6, the finger can be hooked back, and then pull it to pull the clamping block 43 open. When in use, during the process of inserting the fixing rod 41 into the side wall of the jack 4, under the action of the limiting plate 7, the fixing rod 41 can slide towards the middle of the surrounding limiting plates 7.
