as shown in fig. 2, the end of the abutment bar 18 contacts the outer contour of the guide cam 14 at this time, and when the end of the abutment bar 18 rotates to the position B, the elastic force of the first compression spring 17 is released, so that the push plate 16 moves radially on the rectangular limit bar 15 toward the guide cam 14;
the synchronous lifting of the first disc 4 is driven by the lifting of the guide cam 14.
Further, the surface of the push plate 16 is fixedly connected with two symmetrical inclined guide rods 19, the opposite surfaces of the two plugging plates 3 are fixedly connected with vertical connecting plates 20, the top of each vertical connecting plate 20 is fixedly connected with a horizontal extension rod 21, and inclined through holes matched with the inclined guide rods 19 are formed in the horizontal extension rods 21.
Referring to fig. 2, with the push plate 16 moving, the inclined guide rods 19 thereon move synchronously, since the two plugging plates 3 can only move back to back on the storage box 2, so that the movement of the horizontal extension rods 21 is limited, the two horizontal extension rods 21 can also move back to back on the storage box 2, under the cooperation of the inclined through holes on the horizontal extension rods 21, when the push plate 16 moves radially towards the guide cam 14 with the inclined guide rods 19, the two horizontal extension rods 21 are driven to move back to back, and the two plugging plates 3 are driven by the vertical connecting plate 20 to move back to back, so that the table tennis balls stored in the storage box 2 can drop, namely, when the storage box 2 rotates to the position B on the guide cam 14, the table tennis balls stored in the storage box 2 can drop;
the elastic size of the table tennis ball is detected through falling rebound.
Embodiment three, on the basis of embodiment two, further is:
an air inlet hole is formed in the side face of the storage box 2, an air duct 22 is communicated with the air inlet hole, and the air duct 22 is supplied with air by an external air source;
referring to fig. 2, the air duct 22 is in butt joint with the air inlet hole on the surface of the storage box 2, so that air flow can be blown into the storage box 2, table tennis balls stored in the storage box 2 can be blown, dust particles adhered on the surface of the table tennis balls can fall off, influence of the table tennis balls on elastic detection due to the adhesion of the dust particles is avoided, and accuracy of detection results is difficult to ensure; the external air source is an air pump.
Further, the surface fixedly connected with locating lever 23 of storage box 2, the dead axle is rotated and is connected with bend gear 24 in the one end that keeps away from storage box 2 on the locating lever 23, bend gear 24's upper surface and the bottom fixed connection of air duct 22, bend gear 24's one end is run through and axial sliding connection have round platform shape sealed cowling 25 on the air duct 22, bend gear 24's one end is run through and fixed cover has baffle ring 26 on the air duct 22, baffle ring 26 and round platform shape sealed cowling 25's opposite face fixedly connected with pressure spring two 27, horizontal extension bar 21's upper surface fixedly connected with and bend gear 24 go up tooth mesh's pinion rack 28.
When the air inlet on the storage box 2 is in butt joint, the open end of the round table-shaped sealing cover 25 can be tightly contacted with the surface near the air inlet on the storage box 2 and extruded under the elastic action of the pressure spring II 27, so that the air discharged by the air pump can be fully introduced into the storage box 2 to blow the table tennis in the storage box 2;
when the table tennis ball in the storage box 2 rotates to the position B and falls, the horizontal extension rod 21 drives the toothed plate 28 to synchronously move, so that the redirecting gear 24 drives the air guide pipe 22 to rotate along with the toothed plate, and in the rotating process of the air guide pipe 22, the elastic force of the pressure spring II 27 is released due to the fact that the contact with the storage box 2 is released, and the air conveyed by the air guide pipe 22 is guided by the round table-shaped sealing cover 25, so that the air sprayed by the air guide pipe 22 has wider action range and is closer to the axis height of the round table-shaped sealing cover 25, and the influence degree of the air is more obvious;
when the table tennis falls to the ground and rebounds, the table tennis is influenced by the sprayed air, and an initial speed of movement in the horizontal direction exists; the higher the rebound height is, the larger the horizontal pushing force of the sprayed air is, the parabolic motion is finally carried out, and the more visual judgment can be carried out through the distance between the table tennis ball and the ball falling point in the horizontal direction;
further, a spiral partition plate 101 is fixedly connected to the bottom of the inner wall of the disc-shaped box body 1.
Through the setting of spiral baffle 101, can divide into the multilayer with disc box body 1 on the horizontal plane, be convenient for carry out the horizontal restriction to the table tennis that falls in disc box body 1 to and carry out accurate layering and dividing.

through setting up of correction ring 32 and C shape ring 33 for riser 30 overall position keeps stable relative axis of rotation 8, accompanies riser 30's lift, makes synchronizer ring 29 take guide cam 14 to go up and down in step, and then makes disc one 4 of guide cam 14 upper surface go up and down the operation, and then changes the vertical height of storage box 2, is convenient for follow-up multiple experiment that drops.
Further, a screw rod 34 is fixedly connected to the bottom of the vertical plate 30, and a threaded sleeve 35 which rotates on the lower surface of the disc-shaped box body 1 in a fixed shaft is screwed on the screw rod 34.
Referring to fig. 5, the screw sleeve 35 is manually rotated to rotate on the fixed shaft on the lower surface of the disc-shaped box body 1, so that the screw sleeve 35 and the screw 34 rotate relatively, and the vertical plate 30 can only vertically move on the disc-shaped box body 1 after penetrating the disc-shaped box body 1, so that the screw 34 cannot synchronously rotate with the screw sleeve 35, and finally, the screw 34 can synchronously lift and lower with the vertical plate 30, the synchronizing ring 29 on the vertical plate 30 and the guide cam 14 relative to the rotating shaft 8, so that the first disc 4 can vertically move.
Working principle: according to the table tennis elasticity detection equipment, when the table tennis elasticity detection equipment is used, table tennis to be detected is vertically stacked in the storage tube 9, the storage tube 9 is fixedly supported through the connecting frame 10, as shown in fig. 1, at the moment, the storage tube 9, the butt joint tube I6, the butt joint tube II 7 and the storage box 2 are overlapped in a vertical space, so that one table tennis at the bottommost part in the storage tube 9 can fall in the storage box 2, and the table tennis can be blocked by the blocking plate 3 to avoid continuous falling; through rotating, when two shutoff boards 3 of storage box 2 lower surface deviate from mutually and remove, can make the table tennis that is temporarily stored receive gravity influence and free fall, when falling on the interior bottom surface of disc box body 1, through the direct observation fall the back by the table tennis reach the height that rebound, can directly judge the elasticity size of this table tennis, because disc one 4 can carry out axial displacement relative axis of rotation 8, disc two 5 for storage box 2's vertical height can be adjusted, can realize falling ball height's regulation through changing disc one 4, storage box 2's height from this, change this variable, realize the elasticity detection under the multiple environmental factor, enlarge the volume of detection data, improve the accuracy of detection data.
