[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0020] Embodiment 1
[0021] Reference Figures 1 - 5 , a steel structure welding detection device, including a housing 1, an ultrasonic detector 2 is arranged on one side of the housing 1, a first groove 3 is opened in the housing 1, a fixing block 4 is threadedly connected in the first groove 3, and the ultrasonic detector 2 is electrically connected to the fixing block 4. A second groove 5 is opened in the middle of the bottom of the fixing block 4, a moving rod 6 slides in the second groove 5, a moving head 7 is installed at the bottom of the moving rod 6, the edge of the outside of the moving head 7 abuts against the bottom of the housing 1, and the bottom of the moving head 7 extends to the outside of the housing 1. An adjusting mechanism is arranged between the moving rod 6 and the fixing block 4. The adjusting mechanism includes a placement groove 8 opened on the fixing block 4 and a clamping groove 9 opened on the moving rod 6. An inserting rod 10 is placed on the placement groove 8. The inserting rod 10 penetrates through the placement groove 8 and extends into the second groove 5. A spring 11 is installed at one end of the inserting rod 10, and one end of the spring 11 is pressed against the housing 1. The inserting rod 10 in the second groove 5 is arranged in an inclined shape. In one working state, the inclined end of the inserting rod 10 is inserted into the clamping groove 9. Wear-resistant pads 14 are arranged around the bottom of the housing 1.
[0022] Working principle: When an operator holds the ultrasonic detector 2 with one hand and holds the housing 1 with the other hand, the moving head 7 extending from the bottom of the housing 1 will contact the steel structure welding position to be detected. Then, after moving the housing 1 on the steel structure welding position, when there is a bump at the steel structure welding position, the bump on the steel structure will squeeze the bottom of the moving head 7, so that the moving head 7 drives the moving rod 6 to move towards the bottom of the second groove 5, so that the top of the moving rod 6 squeezes the inclined end of the inserting rod 10, so that the inclined end of the inserting rod 10 squeezes the spring 11, making the inclined end of the inserting rod 10 move away from the second groove 5, so that the extrusion of the inserting rod 10 on the top of the moving rod 6 is released, so that the moving head 7 drives the moving rod 6 to continue moving towards the bottom of the second groove 5, so that the clamping groove 9 can reach the position of the inserting rod 10. After the clamping groove 9 reaches the position of the inserting rod 10, under the elastic force of the spring 11, when the inclined end of the inserting rod 10 is inserted into the clamping groove 9, the inserting rod 10 will impact in the clamping groove 9, so that a sound will occur when the inserting rod 10 impacts the moving rod 6, so that the operator knows that there is an abnormality on the surface of the steel structure welding here, and the moving head 7 is also protected.
[0023] Embodiment 2
[0024] On the basis of Embodiment 1, for optimization, refer to Figures 1 - 5 , the placement groove 8, the clamping groove 9, the inserting rod 10, and the spring 11 are all provided with two. The two placement grooves 8, the two clamping grooves 9, the two inserting rods 10, and the two springs 11 are all arranged symmetrically around the moving head 7. Sliding rods 12 are slidably arranged on the two inserting rods 10, and the two springs 11 are respectively sleeved on the two sliding rods 12.
[0025] There are two placement slots 8, two card slots 9, two insertion rods 10, and two springs 11, and the two springs 11 are respectively sleeved on the two sliding rods 12, so that the force on the end of the moving rod 6 that contacts the two insertion rods 10 can be more evenly applied, and the spring 11 is not prone to lateral bending.
[0026] Example 2
[0027] Based on Example 1, optimization is performed. Figures 1 - 5 A stopper 13 is provided at one end of each of the two sliding rods 12 , and one end of each of the two springs 11 is pressed against one side of each of the two stoppers 13 . One side of each of the two stoppers 13 is formed into an arc shape, and the arc-shaped sides of each of the two stoppers 13 are fitted against the inner wall of the housing 1 .
[0028] The stopper 13 can prevent one end of the spring 11 from contacting the housing 1, so that when the fixing block 4 is threadedly installed inside the housing 1, the spring 11 will not rotate and twist with the fixing block 4, so that the spring 11 is not prone to failure.
[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
