[0042] The push-pull mechanism 9 also includes a first rack 92, a first spring 93, a circular plate 94, a push rod 95 and a fixed plate 911. The first rack 92 is slidably connected to the inner wall of the movable sleeve 91. The teeth on the surface of the first rack 92 are only distributed in half of the range, and the smooth part of the surface of the first rack 92 is slidably connected to the inner wall of the movable sleeve 91. The first spring 93 is fixed to one side of the movable sleeve 91, the circular plate 94 is bolted to one end of the first rack 92, and the push rod 95 is bolted to the other end of the first rack 92. The first spring 93 is a compression spring, which causes the first rack 92, the circular plate 94 and the push rod 95 to be subjected to a force away from the box body 3. The top thickness of the box body 3 is relatively large. A transverse groove 96 is provided on the top of the box body 3 to provide a movement range for the push rod 95. A connecting plate 97 is also bolted to the surface of the half tank body 4. A transmission rod 98 is rotatably connected to the surface of the connecting plate 97. A first gear 99 is fixed to the surface of the transmission rod 98, and the first gear 99 and the first rack 92 are meshed with each other. A second gear 910 is fixed to the surface of the rotating rod 73. A connecting rod 912 is rotatably connected to the surface of the fixing plate 911. A third gear 913 is fixed to the surface of the connecting rod 912, and the third gear 913 and the second gear 910 are meshed with each other. The connecting rod 912 and the transmission rod 98 are connected. The first gear 94 is connected to the first gear 99 by a belt drive. Before the test begins, the steel ball used for the test is located in the receiving bucket 121, and the revolving door 72 is manually rotated. In the process of opening the revolving door 72, the revolving door 72 drives the rotating rods 73 on both sides to rotate. The rotating rods 73 drive the connecting rod 912 to rotate in the counterclockwise direction through the second gear 910 and the third gear 913. The connecting rod 912 drives the transmission rod 98 to rotate through the belt, and the transmission rod 98 and the first gear 99 rotate in the counterclockwise direction, so that the first rack 92, the circular plate 94 and the push rod 95 move toward the direction of the box body 3. At the same time, the first spring 93 is in the In the compressed state, the push rod 95 moves into the transverse groove 96. Therefore, during the opening of the revolving door 72, the push rod 95 can move forward. If the previously tested glass cover is placed on the top of the box body 3, the push rod 95 can push the glass cover to the outside for removal. The push-pull mechanism 9 has the function of pushing out the glass cover, and the gear ratio between the second gear 910 and the third gear 913 is 3 to 5:1. When the revolving door 72 rotates more than half a circle, the linkage rod 912 below can rotate several circles, and the transmission rod 98 can rotate several circles to ensure that the movement distance of the push rod 95 is sufficient to push out the glass cover.After the revolving door 72 is opened, the glass cover plate to be tested is aligned with the bend of the side plate 61, and then the glass cover plate is pushed in, and the revolving door 72 is released. At this time, the top of the two sides of the glass cover plate is located below the rubber pad 62. Under the reaction force of the first spring 93, the first rack 92, the circular plate 94 and the push rod 95 move in the direction away from the box body 3, and drive the first gear 99 and the transmission rod 98 to rotate clockwise. The transmission rod 98 drives the connecting rod 912 to rotate clockwise, and the connecting rod 912 drives the rotating rod 73 to rotate counterclockwise through the third gear 913 and the second gear 910, and the revolving door 72 rotates downward. The revolving door 72 is closed, so that the front of the side plate 61 is in a restricted state. At the same time, the glass cover plate located at the top of the box body 3 is restricted by the revolving door 72 and the push rod 95, so that the front and rear restrictions of the glass cover plate are realized. Moreover, under the action of the push-pull mechanism 9, the revolving door 72 in the shielding mechanism 7 can be automatically closed. ;

[0043] Then, the air pump 51 is turned on to generate high-pressure gas. The gas enters the interior of the half tank 4 and the box 3 through the air pipe 52 and the one-way valve 53, which makes the box 3 and the half tank 4 in a state of high-pressure gas. A barometer 13 is arranged at the bottom of the box 3, and the probe end of the barometer 13 is arranged on the inner side of the box 3. When the air pressure inside the box 3 is 400-500kPa, the air pump 51 is turned off. The clamping mechanism 6 also includes vertical grooves 63, movable columns 64, ring bodies 65 and rubber blocks 66. The number of vertical grooves 63 is four groups and they are respectively opened at the four corners of the top of the box 3. The movable columns 64 are slidably connected to the inner wall of the vertical grooves 63. The bottom of the vertical grooves 63 is connected to the cavity inside the box 3 below. The surface of the movable columns 64 is fixed with ring bodies 6 5. The inner wall of the middle part of the vertical groove 63 is partially enlarged, and the ring body 65 is slidably connected with the enlarged inner wall. The ring body 65 limits the movement range of the movable column 64. The rubber block 66 is bonded to the top of the movable column 64. Under the action of the air pressure difference, the movable column 64 moves upward and drives the rubber block 66 upward. The rubber block 66 abuts against the surface of the bottom of the glass cover plate and cooperates with the rubber pad 62 above to form an upper and lower clamping of the glass cover plate. In addition, the rubber block 66 is elastic and will not cause excessive extrusion to the glass cover plate. At the same time, the upward movement range of the movable column 64 is limited by the ring body 65, and it will not move upward too long to cause excessive extrusion to the glass cover plate. At this time, the glass cover plate is above the fixed box body 3 and will not be forced to bounce up or deflect during the detection process.

[0044] The ball throwing mechanism 12 also includes a transverse tube 122, a limiting column 123, a second spring 124, a pull rod 125 and a positioning assembly 129. The receiving bucket 121 is slidably connected to the inner wall of the vertical tube 2. The transverse tube 122 is connected and arranged at the outlet of the receiving bucket 121.

The positioning assembly 129 includes a threaded sleeve 1291, a knob bolt 1292 and a positioning block 1293. The threaded sleeve 1291 is provided on the surface of the slide block 127. The positioning block 1293 is connected to the inner wall of the slide groove 128. The knob bolts 1292 are fixed to each other, and the receiving bucket 121 is moved up and down to adjust the height of the receiving bucket 121. After adjusting to the required height, the knob bolt 1292 is rotated, and it gradually penetrates under the action of the inner wall thread of the threaded sleeve 1291, and then the positioning block 1293 is tightly attached to the surface of the outer side of the vertical tube 2. Under the action of the friction between the positioning block 1293 and the outer surface of the vertical tube 2, the slider 127 and the receiving bucket 121 are positioned, so that the steel ball is thrown at different heights, and the second spring 12 4 is a compression spring. Before the test, the reaction force of the second spring 124 acts on the surface of the limiting column 123, so that the limiting column 123 is located at the outlet below the receiving bucket 121 to prevent the steel ball from falling. After the glass cover is fixed, the limiting column 123 is contracted toward the inside of the horizontal tube 122 by pulling the pull ring 126 to release the restriction on the steel ball. The steel ball falls and hits the surface of the glass cover for testing. After the pull ring 126 is released, the limiting column 123 is automatically reset under the action of the second spring 124.

The vertical plate 113 is bolted to the inside of the box body 112. A through groove 114 is penetrated on the surface of the vertical plate 113. A second connecting pipe 115 is connected to the other side of the box body 112, and the other end of the second connecting pipe 115 is interconnected with the long return pipe 102, so that the box body 3 and the long return pipe 102 are connected together. A mounting plate 116 is also welded inside the second connecting pipe 115, and a gas nozzle 11 is penetrated on the surface of the mounting plate 116. 7. The inlet of the air nozzle 117 is located on one side of the placement plate 116, and the outlet of the air nozzle 117 faces the long return pipe 102. The plugging assembly 118 controls the opening and closing of the through slot 114. The plugging assembly 118 includes a slide rail 1181, a second rack 1182 and a fourth gear 1183. The slide rail 1181 is bolted to the surface of the tilting box 8 and the box body 112 through a connecting rod. The second rack 1182 is slidably connected to the surface of the slide rail 1181, which enables the second rack 1182 to move only in the vertical direction. The fourth gear 1183 is fixed to the surface of the transmission rod 98 and meshes with the second rack 1182. The plugging assembly 118 also includes a lifting plate 1184, a movable rod 1185, and a sliding sleeve 1186. And baffle 1187, the lifting plate 1184 and the second rack 1182 are bolted to each other, the number of sliding sleeves 1186 is two groups and they are respectively set on both sides of the top of the box body 112, the movable rod 1185 is bolted to the bottom of the lifting plate 1184 and slidably connected with the inner wall of the sliding sleeve 1186, and the baffle 1187 is bolted to the bottom end of the movable rod 1185. During the test, part of the air inside the box body 3 will enter the box body 112 through the first connecting pipe 111 and be blocked by the vertical plate 113 and the baffle 1187 to prevent the air inside the box body 3 from escaping. After the test is completed, the steel ball hits the glass cover to end, and then the steel ball rolls along the inclined box 8, and then the steel ball enters the lower return pipe 101 The one-way component 104 includes an inner plate 1041, a through hole 1042, a blocking plate 1043 and a spring hinge 1044. The inner plate 1041 is welded to the inner side of the lower return pipe 101. The through hole 1042 penetrates through the surface of the inner plate 1041. The spring hinge 1044 is bolted to the bottom of the inner plate 1041. The blocking plate 1043 and the movable part of the spring hinge 1044 are bolted to each other. The weight of the steel ball is 1 or 2 kg. When passing through the inner plate 1041 and the through hole 1042, the blocking plate 1043 is opened by the weight of the steel ball, and then the steel ball passes through the through hole 1042 and continues to move downward and enters the lower part of the long return pipe 102. At the same time, under the action of the spring hinge 1044, the blocking plate 1043 is automatically closed;When taking out the tested glass cover, first rotate the revolving door 72 upwards. The revolving door 72 drives the linking rod 912, the transmission rod 98 and the first rack 92 to move the push rod 95 forward and push the glass cover to the outside so as to take out the glass cover. In the process of rotating the revolving door 72, the transmission rod 98 rotates counterclockwise, and the transmission rod 98 drives the fourth gear 1183 to rotate counterclockwise. The fourth gear 1183 drives the second rack 1182 to move upwards. The second rack 1182 drives the lifting plate 1184, the movable rod 1185 and the baffle 1187 to move upwards. The baffle 1187 gradually opens the through slot 114. At this time, the high-pressure gas in the box body 3, the half tank body 4, and the first connecting pipe 111 can enter the second connecting pipe 115 through the through groove 114 on the surface of the vertical plate 113, and then the high-pressure gas is sprayed from the gas nozzle 117. The gas blows to the surface of the steel ball, causing the steel ball to roll along the inside of the long return tube 102, and enter the cylinder 103 from the other end of the long return tube 102. After being buffered by the cylinder 103, it finally passes through the outlet below the cylinder 103 and falls into the receiving bucket 121 at a high place, so as to lift the steel ball. There is no need for the staff to manually put the steel ball back to a high place, which is more convenient to use.
