[0002] A bicycle, also known as a cycle or a bicycle, is usually a small two-wheeled land vehicle. After riding on it, people use pedals as power. It is a green and environmentally friendly means of transportation. According to the large structural frame of the vehicle body, bicycles can be divided into several major categories, such as frames, tires, pedal components, front fork components, chains, flywheels, etc. Among them, tires are the components that are most likely to be damaged in daily use. The air tightness of bicycle tires has become a common problem for bicycles, and air tightness testing equipment is needed for testing.

[0003] The prior art discloses an air tightness detection device for electric bicycle parts with a patent announcement number of CN218956011U. The above patent provides a pushing mechanism, which can eliminate the step of manually pressing the wheel when the air tightness of the wheel needs to be checked. Instead, the wheel is pressed by a component, which is more convenient. In addition to the steps of placing and taking the wheel, the hands no longer need to touch the water, which improves the usability. However, in actual use, the following shortcomings still exist: due to the influence of buoyancy, the tire is easy to float in the water and is not easy to be immersed in the liquid. In addition, it is not easy to observe the leakage point of the tire placed statically in the detection equipment, which affects the efficiency of the tire air tightness detection.

[0004] Therefore, an air tightness testing device is needed to solve the problem in the prior art that the tire is easy to float in water and the leakage point is not easy to observe when the tire is placed still in the testing device. Utility Model Content

Connecting rods 45 are hinged between the outer walls of both sides of the movable block 43 and the two clamping blocks 44 respectively.

[0024] Further as Figure 1 As shown, it is worth explaining in detail that the bottom end of the transparent water tank 1 is fixedly connected to a bottom plate 6, one end of the top surface of the bottom plate 6 is fixedly connected to an L-shaped plate 7, the top surface of the transverse section of the L-shaped plate 7 is fixedly connected to a drive motor 8, the output end of the drive motor 8 passes through the bottom surface of the transverse section of the L-shaped plate 7 and is coaxially fixedly connected to a mounting plate 9, an electric push rod 10 is fixedly connected at the center of the bottom surface of the mounting plate 9, and the output end of the electric push rod 10 is coaxially fixedly connected to a pressure plate 11.

[0025] Further as Figure 2 and Figure 4As shown, it is worth explaining in detail that the locking assembly 5 includes two symmetrically distributed U-shaped plates 51 and two symmetrically distributed plug plates 52, the two U-shaped plates 51 are distributed and fixedly connected on both sides of the outer surface of the supporting plate 3, and the two plug plates 52 are respectively fixedly connected on both sides of the outer surface of the pressure plate 11, an insert rod 53 is slidably inserted into the outer wall of one side of the U-shaped plate 51, and a round block 54 is coaxially fixedly connected to the outer wall of one side of the insert rod 53, a spring 55 is sleeved on the outer surface of the insert rod 53, one side of the spring 55 is fixedly connected to the outer wall of one side of the U-shaped plate 51, and the other side of the spring 55 is fixedly connected to the outer wall of one side of the round block 54, a slot 56 is opened on the outer wall of one side of the plug plate 52, and the side of the insert rod 53 away from the round block 54 is inserted into the slot 56.

[0026] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a plurality of circumferentially distributed limiting columns 12 are fixedly connected to the top of the supporting plate 3 , and a tire body 13 is placed on the top of the supporting plate 3 .

[0027] Further Figure 3 As shown, it is worth specifically explaining that the height of the second elastic telescopic rod 41 is greater than the height of the limiting column 12, which facilitates the second elastic telescopic rod 41 to extend and retract up and down, thereby pushing the clamping block 44 to move, and the outer wall of the clamping block 44 away from the connecting rod 45 is set to an arc shape, which is convenient for clamping the tire body 13.

[0028] Further Figure 4 As shown, it is worth explaining in detail that the bottom surface of the plug plate 52 is set to be arc-shaped, and the side of the plug rod 53 away from the round block 54 is set to be arc-shaped, so that the plug plate 52 can push the plug rod 53 when moving downward, thereby facilitating the plug rod 53 to be inserted into the slot 56.

[0029] In summary: when the device is in use, first place the tire body 13 on the top surface of the supporting plate 3 and between the clamping block 44 and the limit column 12, then turn on the electric push rod 10, and the electric push rod 10 pushes the pressure plate 11 to move downward. During the downward movement of the pressure plate 11, its bottom end contacts the top surface of the movable block 43. As the pressure plate 11 continues to move downward, under the action of the second elastic telescopic rod 41, the movable block 43 is forced to move downward, and the two clamping blocks 44 are pushed by the connecting rod 45 to clamp and fix the tire body 13. Under the action of the first elastic telescopic rod 2, the electric push rod 10 pushes the supporting plate 3 to drive the tire body 13 to move downward into the transparent water tank 1, and the air tightness of the tire body 13 is tested, which effectively avoids the problem of the tire floating easily in the water.

[0030] When the pressure plate 11 moves to the bottom end and contacts the top of the limit column 12, the plug plate 52 moves downward with the pressure plate 11. The bottom surface of the plug plate 52 is set as an arc surface to push one side of the plug rod 53 which is also set as an arc surface. After the plug rod 53 is stressed, it shrinks through the spring 55. When the plug plate 52 moves downward to the slot 56 and the plug rod 53 are at the same level, the plug rod 53 is bounced into the inside of the slot 56 under the action of the spring 55, and the pressure plate 11 is locked. After the tire body 13 moves downward to the inside of the transparent water tank 1, the drive motor 8 is turned on, and the drive motor 8 drives the mounting plate 9 and the electric push rod 10 to rotate slowly, so that The pressure plate 11 is driven to rotate, and under the action of the locking assembly 5, the supporting plate 3 and the pressure plate 11 are rotated synchronously, so that the tire body 13 is rotated in the transparent water tank 1, which is convenient for observing the tire body 13. After the air tightness test of the tire body 13 is completed, the electric push rod 10 is started to drive the tire body 13 to move upward to the outside of the transparent water tank 1, and at the same time, the two round blocks 54 are pulled to separate the insertion rod 53 from the slot 56. At the same time, the electric push rod 10 is started again to drive the pressure plate 11 away from the supporting plate 3, so that the tire body 13 can be removed, which effectively avoids the problem that the tire is placed statically in the testing equipment and it is difficult to observe the leakage point.

[0031] The drive motor 8 and the electric push rod 10 can be purchased on the market. The drive motor 8 and the electric push rod 10 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
