[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0016] like Figure 1-3 As shown, a desktop air tightness tester includes a shell 1 and a tester body 2. The shell 1 is hollow with an opening upward. The tester body 2 can be raised and lowered along the height direction of the shell 1. When testing is required, the tester body 2 can be moved to the inside of the shell 1 to seal the tester body 2 in the shell 1, so that the tester body 2 can be effectively sealed from the external environment when working, preventing dust particles and other impurities in the external environment from affecting the test results, thereby improving the test efficiency. Conversely, when the tester body 2 is moved to the top of the shell 1, the product can be conveniently placed in the tester body 2 for testing. A mounting portion is provided in the shell 1, and the tester body 2 is installed on the mounting portion. The mounting portion can drive the tester body 2 to rise and fall along the height direction of the shell 1, so that the position of the tester body 2 can be conveniently adjusted. A closing portion is provided for closing the top of the shell 1. The closing portion has two states, open and closed. When the detector body 2 moves to the top of the shell 1, the closing portion is in the open state. At this time, the product can be conveniently placed in the detector body 2. When the detector body 2 moves downward into the shell 1, the closing portion can be switched from the open state to the closed state. At this time, the closing portion can close the top of the shell 1 and seal the detector body 2 in the shell 1. At this time, the detector body 2 can be made more convenient for detection work. A connecting portion is provided in the shell 1. When the mounting portion drives the detector body 2 to move downward, the closing portion can be switched from the open state to the closed state. When the mounting portion drives the detector body 2 to move upward, the closing portion can be switched from the closed state to the open state. Therefore, when the mounting portion is working, the closing portion can be conveniently driven by the connecting portion to switch between the two states.
[0017] like Figure 1As shown, the mounting portion includes a mounting plate 31 slidably connected to the shell 1, and the detector body 2 is mounted on the mounting plate 31. The bottom surface of the mounting plate 31 is fixedly connected to two brackets 32. The mounting plate 31 and the bracket 32 can be lifted and lowered along the height direction of the shell 1, thereby driving the detector body 2 to be lifted and lowered along the height direction of the shell 1. A connecting block 33 is fixedly connected to one of the brackets 32. The bottom surface of the connecting block 33 is provided with a threaded groove 34. A threaded rod 35 is connected to the inner thread of the threaded groove 34, and the bottom end of the threaded rod 35 is rotatably connected to the inner bottom wall of the shell 1. The threaded rod 35 is connected to an external driving source so that the threaded rod 35 rotates. When the threaded rod 35 rotates, it can drive the connecting block 33 to be lifted and lowered. When the connecting block 33 is lifted and lowered, it can drive the bracket 32 and the mounting plate 31 to be lifted and lowered, thereby conveniently adjusting the position of the detector body 2.
[0018] like Figure 1-3 As shown, the closing portion includes two first baffles 41 slidably connected to the top of the shell 1. The two first baffles 41 can move toward or away from each other along the length direction of the shell 1. The ends of the two first baffles 41 that are away from each other are hinged with a second baffle 42. When the ends of the two first baffles 41 that are close to each other are in contact, the first baffle 41 and the second baffle 42 can close the top of the shell 1. At this time, it is in a closed state, and the detector body 2 can be conveniently enclosed in the shell 1. On the contrary, when the ends of the two first baffles 41 that are close to each other are not in contact, it is in an open state.
[0019] like Figure 2 and Figure 3As shown, the connecting portion includes two threaded blocks 51 respectively fixedly connected to the back of the two first baffles 41, the two threaded blocks 51 are internally threaded with a bidirectional screw rod 52, the surface of the bidirectional screw rod 52 is fixedly connected to a first bevel gear 53, the back of the housing 1 is rotatably connected to a rotating shaft 55, the top of the rotating shaft 55 is fixedly connected to a second bevel gear 54, and the second bevel gear 54 is meshed with the first bevel gear 53, the back of the housing 1 is rotatably connected to a fourth bevel gear 57, the bottom end of the rotating shaft 55 is fixedly connected to a third bevel gear 56, and the third bevel gear 56 is meshed with the fourth bevel gear 57, a gear 58 is provided inside the housing 1, and the gear 58 is connected to the It is fixedly connected to the fourth bevel gear 57 through the connecting shaft, and a rack 59 is fixedly connected to the side of the connecting block 33 close to the gear 58, and the rack 59 and the gear 58 have an overlapping position. When the connecting block 33 moves downward, the rack 59 can engage with the gear 58, and the movement of the rack 59 can drive the gear 58 to rotate, and then the rotation of the gear 58 can drive the fourth bevel gear 57 to rotate, and then the rotation of the fourth bevel gear 57 can drive the bidirectional screw rod 52 to rotate, and when the bidirectional screw rod 52 rotates, it can drive the first baffle 41 to move, so that the first baffle 41 can be driven to move when the detector body 2 is raised and lowered.
[0020] Working principle: First, place the product to be tested in the detector body 2, and then start the installation part. The installation part can drive the detector body 2 to move downward, so that the detector body 2 moves to the inside of the shell 1. When the installation part is working, it can drive the connecting part to work, and then the connecting part can drive the closing part to switch from an open state to a closed state. After the closing part seals the top of the shell 1, the detector body 2 is started to perform the detection work, so that the detector body 2 can be effectively sealed from the external environment when it is working, preventing impurities such as dust particles in the external environment from affecting the detection results, thereby improving the detection efficiency.
