According to the invention, the rim of the pinch roller A16 matched with the pull rope 51 is rough, so that the rotation of the pinch roller A16 can drive the pull rope 51 to be effectively retracted and released.
The working flow of the invention is as follows: in the initial state, the sliding seat 4 is in the lowest limit state of the upright post 2, the supporting plate 6 is just on the base 1, the baffle A39 is in a closed state to the falling hole 7 on the supporting plate 6, the steel ball 52 at the tail end of the pull rope 51 is just on the baffle A39, the stretching part between the cross beam 9 and the supporting plate 6 is in a stretched state, the two baffles B41 are in a closed state, and the steel wool 43 in the circular groove 42 on the baffles B41 is in a clamping state to the pull rope 51. The spiral spring a35 is in a compressed state. The volute spring B49 in the belt wheel mechanism 27 is in a compressed state, the clamping block A36 circumferentially abuts against the clamping block B37, the threaded sleeve 30 is located at the limit position, close to the cross beam 9, in the belt wheel B28, and the annular sleeve 33 is located at the limit position, far away from the cross beam 9, in the threaded sleeve 30. Both lock bars 11 are inserted into the corresponding limit grooves 3 of the upright posts 2 to lock the sliding seat 4.
When the invention is used for testing the impact strength of the steel ball 52 on the flexible glass, the falling height of the initial steel ball 52 is adjusted according to the requirement of the light test of the flexible glass, the pull ring 13 is pulled to drive the two lock rods 11 to separate from the corresponding limit grooves 3 to unlock the sliding seat 4, the sliding seat 4 is pushed to move vertically upwards to the required height on the upright post 2, and meanwhile, the sliding seat 4 drives the supporting plate 6 and the cross beam 9 to synchronously move and communicate with each other. The support plate 6 moves the steel ball 52 to a desired height by the shutter a 39.
Meanwhile, the gear A22 drives the belt wheel B28 to rotate through the gear B23, the wheel shaft C24, the clamping block A36, the clamping block B37 and the threaded sleeve 30 under the drive of the rack A15, the belt wheel B28 drives the pinch roller A16 to rotate through the synchronous belt 26, the belt wheel A25 and the wheel shaft A17, the pinch roller downwards discharges the end part of the steel ball 52 of the pull rope 51 pressed by the pinch roller B18, the winding wheel 47 rotates under the pull rope 51 and further compresses the vortex spring A35, meanwhile, the pinch roller A16 rotates under the pull rope 51 pull of the pinch roller B18, and the downwards discharged pull rope 51 is piled on the two baffle plates B41.
When the steel balls 52 reach the required height, the length of the pull ropes 51 piled on the two baffle plates B41 is equal to the rising height of the steel balls 52, so that the steel balls 52 can effectively impact the flexible glass placed on the base 1 after falling, the splashing distance of the small balls after impact is not too large, the speed of pulling the small balls is increased, and the impact test efficiency is improved.
Next, a flexible glass requiring test strength is prevented on the base 1.
Then, the connecting rod B40 is pulled, the connecting rod B40 drives the baffle A39 to open the falling hole 7, meanwhile, the connecting rod B40 drives one baffle B41 to move, the baffle B41 connected with the connecting rod B40 drives the other baffle B41 to open through the rack B45 and the gear C46, and the opening speed of the two baffles B41 is faster than that of the baffle A39 to open the falling hole 7.

The steel ball 52 will splash after striking the flexible glass on the base 1, and because the length of the pull rope 51 is substantially the same as the distance between the cross beam 9 and the base 1, the steel ball 52 can be quickly pulled back without splashing too far, the steel ball 52 is returned to above the support plate 6 through the drop hole 7 again and the baffle A39 is closed so that the steel ball 52 is located on the baffle A39, and meanwhile, the accumulated part of the pull rope 51 is sent to above the baffle B41 before the two baffles B41 are closed. The impact strength test of the steel ball 52 on the flexible glass is completed by repeating the above steps several times.
When the lateral impact strength test is required to be carried out on the glass on the base 1, the baffle A39 is firstly opened in an initial state, the two baffles B41 can be opened, the steel ball 52 is in a suspended state, then the height of the sliding seat 4 is regulated, after the height of the supporting plate 6 is regulated as required, the steel ball 52 is laterally swung to a certain height, and the flexible glass is placed on the base 1 in a laterally impacted state. Then, the hands are loosened, and the steel ball 52 swings to the flexible glass with the falling hole 7 as a swinging point under the action of dead weight and the traction of the pull rope 51 to finish the lateral impact strength test.
When it is necessary to perform an impact resistance test on the connection of the flexible glass, the pellet is removed from the string 51 in an initial state, and the glass piece 53 welded with the glass hook is hooked on the baffle a39 at the end of the string 51 and below the drop hole 7. Then, the base 1 is removed, the height of the glass piece 53 to be dropped is adjusted as required, after the height adjustment is finished, the baffle A39 and the baffle B41 are opened, the glass piece 53 is dropped in a free falling manner, and finally the impact strength test of the connection of the glass piece 53 is completed.

According to the invention, through the stay cord 51 with the corresponding length, the steel ball 52 can be pulled back for repeated testing after the steel ball 52 and the glass are impacted to fly sideways while the interference of the stay cord 51 to the steel ball 52 and the glass is avoided after the steel ball 52 falls freely, and the testing efficiency of the steel ball 52 vertically impacting the glass is improved.
According to the invention, the swinging point of the pull rope 51 provided by the round groove 42 on the supporting plate 6 can enable the pull rope 51 to drive the steel ball 52 to perform lateral impact test on flexible glass on the base 1, and the height of the swinging point of the pull rope 51 is adjustable, so that the impact direction, lateral speed and strength of the steel ball 52 on the glass are effectively enriched.
According to the invention, after the falling height of the steel ball 52 is adjusted, the enough length of the pull rope 51 can be ensured, the stressed part of the pull rope 51 is only arranged on the pull rope 51 part between the pinch roller A16 and the pinch roller B18 and the base 1, but not the whole pull rope 51 is stressed, the whole stress frequency of the pull rope 51 is reduced, and when the pull rope 51 part between the pinch roller A16 and the pinch roller B18 and the base 1 fails due to repeated stress damage, a new pull rope 51 can be pulled out from the winding wheel 47 to pull the steel ball 52, so that the replacement efficiency of the pull rope 51 is improved.
According to the invention, the tail ends of the part of the pull ropes 51 between the pinch roller A16 and the pinch roller B18 and the base 1 are hooked with the hanging rings 54 welded on the flexible glass to replace the steel balls 52, so that the glass piece 53 freely falls from the supporting plate 6 to perform the flexible glass connection impact resistance test, and the operation is convenient and quick.
The baffle A39 and the two baffles B41 can effectively prevent the stay cord 51 from knotting due to accumulation, so that the stay cord 51 falls along with the steel ball 52 or the glass piece 53 in the falling process of the steel ball 52 or the glass piece 53.
