Technical Field

[0001] The utility model relates to the technical field of sports goods manufacturing, in particular to volleyball air leakage detection equipment. Background Art

[0002] Volleyball is a ball sport. The court is rectangular with a high net in the middle. Each team occupies one side of the court. Players use their hands to hit the ball over the net. The ball used in volleyball is made of sheepskin or artificial leather as the shell and rubber as the bladder. It is similar in size to a football.

[0003] At present, quality inspection is particularly important in the production process of volleyballs. Among them, air leakage detection is one of the links of quality inspection. When performing air leakage detection on exhaust, the detection method of existing technology often relies on manual sampling detection, which is time-consuming and labor-intensive. In addition, sampling detection may easily lead to the possibility that leaking volleyballs may not be detected, resulting in certain risks for volleyballs entering the market. Therefore, we proposed volleyball air leakage detection equipment to solve the above problems. Utility Model Content

[0020] Reference Figure 1-4The volleyball air leakage detection device comprises a water tank 1 and a water inlet 2 and a drain hole 3 arranged on the outer wall of the water tank 1. Two slide plates 4 are slidably connected to the inner wall of the water tank 1. The inner bottom of the water tank 1 and the top and bottom of the slide plate 4 are inclined.

[0021] The two slide plates 4 are connected by a plurality of movable threaded sleeves 5. A plurality of through holes are provided on the top of the slide plate 4. The outer wall of the movable threaded sleeve 5 is fixedly connected to the inner wall of the two coaxial through holes. The outer wall of the water storage tank 1 is fixedly connected to a drain pipe connected to the drain hole 3. A drain valve 15 is fixedly provided on the outer wall of the drain pipe. The purpose of providing the drain valve 15 is to facilitate the replacement of clean water in the water storage tank 1.

[0022] A plurality of threaded rods 6 are rotatably connected to the bottom of the water tank 1, a threaded hole is provided at the top of the movable threaded sleeve 5, the outer wall of the threaded rod 6 and the inner wall of the threaded hole are threadedly connected, a servo motor 7 is fixedly connected to the bottom of the water tank 1, the output shaft of the servo motor 7 and the plurality of threaded rods 6 are connected by a synchronous chain 8, and the output shaft of the servo motor 7 and the outer wall of the threaded rod 6 are sleeved with a chain plate adapted to the synchronous chain 8, and the function of the synchronous chain 8 is to allow the output shaft of the servo motor 7 to drive the plurality of threaded rods 6 to rotate synchronously, so as to facilitate the synchronous lifting of the plurality of movable threaded sleeves 5;

[0023] A fixing opening 9 is provided at the top of the skateboard 4, and a first mesh plate 10 is fixedly connected to the inner wall of the fixing opening 9 at the bottom, and two rotating shafts are rotatably connected to the inner wall of the fixing opening 9 at the top, and a second mesh plate 11 is fixedly sleeved on the outer wall of the rotating shaft, and two lifting handles 14 are fixedly connected to the top of the second mesh plate 11, and a strap 12 is fixedly connected to the inner wall of the fixing opening 9 at the top, and two T-shaped handles 13 are rotatably connected to the top of the strap 12, and a plurality of ventilation holes are provided on the tops of the first mesh plate 10 and the second mesh plate 11.

[0024] Working principle: When the volleyball needs to be tested for air leakage, clean water can be injected into the water tank 1 through the water inlet 2. At this time, the drain valve 15 is in a closed state, so that the water tank 1 is filled with clean water. The initial state of the device is that the slide plate 4 at the bottom is completely immersed in clean water;

[0025] The worker is asked to hold the lifting handle 14 to open the two second grid plates 11, and put the multiple volleyballs to be tested into between the two slide plates 4 through the fixing opening 9 at the top, and the worker is asked to close the two second grid plates 11 and rotate the two T-shaped handles 13 so that the two T-shaped handles 13 fix the two second grid plates 11;

[0026] The output shaft of the servo motor 7 is started to rotate forward, and the output shaft of the servo motor 7 drives one of the threaded rods 6 to rotate forward, and the threaded rod 6 drives the other threaded rod 6 to rotate forward through the synchronous chain 8, and the threaded rod 6 drives the movable threaded sleeve 5 to descend, and the movable threaded sleeve 5 drives the multiple volleyballs to be detected between the two slide plates 4 and the first mesh plate 10 and the second mesh plate 11 to descend;

[0027] When all the volleyballs to be tested have entered the clean water of the water tank 1, the servo motor 7 is turned off, and the worker is asked to observe whether there are bubbles on the water surface. If no bubbles are generated, then this batch of volleyballs has no air leakage problem. If bubbles are generated, then this batch of volleyballs has air leakage problem and needs to be retested. After the volleyballs are tested, the output shaft of the servo motor 7 is started to reverse;

[0028] The output shaft of the servo motor 7 drives the volleyball that has been tested between the two slide plates 4 and the first grid plate 10 and the second grid plate 11 to move upward until the two slide plates 4 return to the initial position, and the servo motor 7 is turned off. Since the two slide plates 4 are inclined, the volleyball will roll along the inclined surface of the slide plates 4 until all the volleyballs that have been tested have rolled down from the top of the first grid plate 10. When a new volleyball needs to be tested again, the above process is repeated to complete the test of the volleyball.

[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.
