Detailed Description of the Embodiment

[0018] The following further describes the specific embodiments of the present utility model with reference to the drawings.

[0019] As Figure 1 and Figure 2 shown, a penetrant testing device includes a spray can body 1 and a mounting part 2. The mounting part 2 includes a fixing block 21. One end of the fixing block 21 is provided with a groove 22. The spray can body 1 is located in the groove 22 and is used for spraying the workpiece. The spray can body 1 can translate along the length direction of the mounting part 2. When the spray can body 1 is located in the groove 22, the groove 22 can receive and temporarily store the spray can body 1. When the spray can body 1 moves to the outside of the groove 22, the spray can body 1 can spray the workpiece. A driving part 3 is provided on the fixing block 21 and is used for driving the spray can body 1 to move, so that the spray can body 1 can be conveniently switched between the working state and the non-working state. Two symmetrically arranged wiping plates 4 are slidably connected to one end of the fixing block 21 close to the spray can body 1, and the two wiping plates 4 are respectively located on both sides of the groove 22. The two wiping plates 4 can move towards or away from each other along the height direction of the fixing block 21. When the two wiping plates 4 move away from each other, the spray can body 1 can move out of the groove 22 to spray the workpiece. When the two wiping plates 4 move towards each other, the spray can body 1 can move into the groove 22, and the mutually close ends of the two wiping plates 4 are in contact with each other to wipe the workpiece. A connecting part 5 is provided on the fixing block 21. When the spray can body 1 moves, the wiping plates 4 can be driven to move through the connecting part 5, so that the spray can body 1 and the wiping plates 4 can be conveniently moved synchronously.

[0020] As Figure 1As shown in the figure, the driving part 3 includes a sealing plate 33 slidably connected to the groove 22. The spray can body 1 is installed on the sealing plate 33. One end of the sealing plate 33 away from the spray can body 1 is rotatably connected to a threaded rod 32, and one end of the threaded rod 32 away from the sealing plate 33 extends to the outside of the fixed block 21. An internally threaded tube 31 is sleeved on the surface of the threaded rod 32, and the internally threaded tube 31 is threadedly connected to the threaded rod 32. One end of the internally threaded tube 31 close to the fixed block 21 is fixedly connected to the fixed block 21. A button is arranged on the internally threaded tube 31, and the button is electrically connected to the spray can body 1. By pressing the button, the spray can body 1 can spray the workpiece. By holding the internally threaded tube 31 with one hand and rotating the threaded rod 32 with the other hand, the sealing plate 33 can be driven to move in the groove 22, so that the spray can body 1 on the sealing plate 33 can be moved out of the groove 22 or moved into the groove 22, and the spray can body 1 can be switched between the working state and the non-working state.

[0021] As Figure 2 shown in the figure, the connecting part 5 includes two cavities 51 opened at the top and bottom of the fixed block 21. Connecting boxes 52 corresponding to the cavities 51 are fixedly connected to the bottom and top of the two fixed blocks 21, and the cavities 51 and the connecting boxes 52 are communicated. Limiting plates 53 are fixedly connected to both cavities 51. Connecting rods 54 are slidably connected to both limiting plates 53. One end of each of the two connecting rods 54 away from each other sequentially penetrates through the limiting plate 53 and the connecting box 52 and extends to the outside of the connecting box 52. Connecting plates 55 are fixedly connected to one end of each of the two connecting rods 54 away from each other, and one end of the connecting plate 55 away from the connecting rod 54 is fixedly connected to the wiping plate 4. One end of each of the two connecting rods 54 close to each other is fixedly connected to a first sealing plug 56 for sealing the cavity 51. A second sealing plug 57 adapted to the connecting box 52 is sleeved on the surface of the connecting rod 54, and the second sealing plug 57 is located in the connecting box 52 for sealing the connecting box 52. One end of the fixed block 21 away from the spray can body 1 is fixedly communicated with a connecting pipe 58, and the other end of the connecting pipe 58 is fixedly connected to the connecting box 52. One end of the connecting box 52 close to the connecting box 52 is located between the first sealing plug 56 and the second sealing plug 57. When the sealing plate 33 moves, the air pressure between the sealing plate 33 and the inner bottom wall of the groove 22 will change. Then the air in the cavities 51 and the connecting boxes 52 will enter the fixed block 21 through the connecting pipe 58. Then the air pressure in the cavities 51 and the connecting boxes 52 will also change. Then the connecting rod 54 will move. When the connecting rod 54 moves, the wiping plate 4 can be driven to move through the connecting plate 55. Thus, when the spray can body 1 moves towards the outside of the groove 22, the two wiping plates 4 can move away from each other, enabling the spray can body 1 to spray the workpiece. When the spray can body 1 moves towards the inside of the groove 22, the two wiping plates 4 can move towards each other to close the groove 22, protect the spray can body 1, and wipe the workpiece.

[0022] As Figure 1 shown, a lighting lamp 7 is installed at one end of the sealing plate 33 close to the spray can body 1 to provide lighting during the working state, enabling workers to perform spraying more conveniently.

[0023] As Figure 1 shown, a camera 8 is installed at one end of the sealing plate 33 close to the spray can body 1 for shooting the working process and checking each detection process.

[0024] As Figure 1 shown, a holding part 9 is arranged on the internal thread pipe 31, which can more conveniently hold the internal thread pipe 31 and more conveniently drive the threaded rod 32 to rotate. The holding part 9 includes a fixing ring 91 sleeved on the surface of the internal thread pipe 31. One end of the threaded rod 32 far from the fixed block 21 is fixedly connected with a turning handle 92. By holding the fixing ring 91 to fix the internal thread pipe 31, and then turning the turning handle 92, the rotation of the turning handle 92 can drive the threaded rod 32 to rotate.

[0025] Working principle: First, install the spray can body 1, the lighting lamp 7 and the camera 8 on the sealing plate 33. The lighting lamp 7 provides lighting for the spraying work, and the camera 8 records the whole process of the work, which is convenient for checking the detection process. Then, by rotating the threaded rod 32, the threaded rod 32 can drive the spray can body 1 to move towards the outside of the groove 22. At this time, the two wiping plates 4 move away from each other, and then the spray can body 1 can be moved to the outside of the groove 22. Then press the button to control the nozzle of the spray can body 1 to spray. When wiping is needed after spraying, move the spray can body 1 towards the inside of the groove 22. Then the two wiping plates 4 will move towards each other to enclose the spray can body 1, the lighting lamp 7 and the camera 8 in the groove 22 for protection to prevent the nozzle of the spray can body 1 from being contaminated. When the two wiping plates 4 are in contact with each other, the workpiece can be wiped, thereby reducing the workload of detection and enabling workers to work conveniently.
