This device can be directly adsorbed with the steel structure through the No. 1 magnetic block. When in use, the ultrasonic probe directly contacts the outer surface of the steel structure, so that the ultrasonic probe can be in contact with the steel structure for a long time without the need for manual long-term pressure. The hook is hung inside the card slot, so that the ultrasonic probe has a good placement position, avoids the ultrasonic probe and the data line from hanging, and better protects the ultrasonic probe. However, the patent still has the following problems in actual use:

[0003] Some ultrasonic flaw detectors now have a suitcase for transportation. However, when the detector is moved by hand in a small area, the detection head and the wire are easily entangled and collided with the outside world, resulting in detection errors. After the detection head in the above-mentioned device is fixed by the buckle, it lacks a fixed structure to keep it firmly connected with the slot. Otherwise, the detection head may be pulled out of the slot or even broken due to the pulling of the wire by the outside world. In addition, when pressing the detection head to make it fit the steel structure, the friction may be too large due to the difficulty in controlling the pressing pressure, making it more difficult to move the detection head.

[0004] An ultrasonic detection device for building steel structure is proposed to solve the above problems. Utility Model Content

[0027] A fixing assembly 3 is provided on the side of the detection head 103 and the detection body 101. The fixing assembly 3 includes a hand-held shell 301 fixedly connected to the top surface of the detection head 103. Both sides of the hand-held shell 301 are provided with a sliding mechanism 2.

[0028] Among them, a connection compartment 302 is fixedly connected to one side of the handheld shell 301 close to the wire 102, a plug-in block 314 is fixedly connected to the bottom of the handheld shell 301, and a connection slot 303 is fixedly connected to the side of the detection body 101, and the connection slot 303 is engaged with the plug-in block 314;

[0029] Among them, the bottom end of the connecting slot 303 is fixedly connected to a fixing block 304, and the inside of the fixing block 304 is rotatably connected to a snap rocker 309, and the top of the snap rocker 309 extends out of the top surface of the fixing block 304 and engages with the connecting compartment 302; after the handheld shell 301 is inserted into the connecting slot 303, the plug-in block 314 will be inserted into the bar groove on the connecting slot 303, and when it slides to the bottom of the connecting slot 303, it will first squeeze the top of the pop-up spring 311 to shrink it, and due to the inclined surface of the top of the snap rocker 309, the connecting compartment 302 will squeeze the snap rocker 309 to rotate first, and then engage with the connecting compartment 302.

[0030] A straight rod 305 is connected to the side of the fixed block 304, and a threaded section 306 is provided on the straight rod 305. The threaded section 306 is threadedly connected to a fixed screw sleeve 307.

When the fixed screw sleeve 307 is engaged with the threaded section 306, the engagement between the buckle rocker 309 and the connecting compartment 302 can be locked to prevent the device from falling and causing the micro spring 310 to contract, thereby releasing the engagement between the above two.

[0031] The other end of the straight rod 305 is rotatably connected to a transfer block 308, which is rotatably connected to the middle part of the snap rocker 309. The other side of the middle part of the snap rocker 309 is rotatably connected to a micro spring 310, which is rotatably connected to the inner wall of the fixed block 304.

At this time, the detection head 103 can stably fit the steel structure plane, and the detection head 103 will not shake randomly due to the instability of holding, thereby affecting the detection result.

[0035] Working principle: Before using this kind of building steel structure ultrasonic detection device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, when the detection head 103 is used, the threaded knob 201 can be rotated according to the surface shape of the steel structure, so that the connecting plate 202 drives the support rod 204 to move up and down, and finally when the bottom of the detection head 103 is in contact with the surface of the steel structure, the roller 205 can slide on the surface of the steel structure;

[0036] When moving in the same building or small area, it is necessary to first insert the plug block 314 of the handheld shell 301 into the connecting slot 303, at which time the detection head 103 will squeeze the pop-up spring 311, and then the buckle rocker 309 will be inserted into the connecting compartment 302 and pushed by the micro spring 310, so that the two remain engaged, at which time the threaded section 306 of the straight rod 305 and the fixed screw sleeve 307 remain in contact, and then the straight rod 305 is rotated to make the fixed screw sleeve 307 engage with the threaded section 306, at which time the straight rod 305 pulls the buckle rocker 309 to move outward, and finally the buckle rocker 309 and the connecting compartment 302 are locked;
