Description of drawings
Fig. 1 is the utility model structural representation (jack-up state).
Fig. 2 is the utility model structural representation (falling state).
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
as shown in Figure 1, the utility model comprises frame 100, frame 100 is provided with wooden platen 1, vertical straight-line ball axle sleeve 11 is installed on the frame 100 under platen 1, push rod 5 slides in straight-line ball axle sleeve 11, the upper end of push rod 5 connects Wooden tray 2, pallet 2 can move up and down along straight-line ball axle sleeve 11 on push rod 5, the lower end of push rod 5 is provided with push rod head 13, back-moving spring 12 supports and is contained between push rod head 13 and straight-line ball axle sleeve 11, the upper end of straight-line ball axle sleeve 11 is provided with buffer stopper 10, push rod head 13 offsets with cam 14, the height point of cam 14 and the distance between low spot are 50 millimeters, cam 14 connects the output shaft of reductor 15, reductor 15 connects buncher 3.Platen 1 is provided with two vertical rods 9, transverse arm 8 is slidably mounted on respectively the top of vertical rod 9, the medial extremity of transverse arm 8 is provided with roller 6, transverse arm 8 is fixing by locking handgrip 7, during test, the position of adjusting on transverse arm 8 props up by the side of test agent 4 soft limit roller 6, with the fixing transverse arm 8 of locking handgrip 7, prevents so higher by test agent lateral shift when falling.Roller 6 prevents tested sample surfaces injury for the roller on soft limit is installed.
Before test, be placed on pallet 2 by test agent (audio and video equipments such as televisor, stereo set) 4, during test, buncher 3 is rotated counterclockwise by reductor 15 band moving cams 14, with push rod head 13 effects, make push rod 5 drive pallet 2 under the guiding of straight-line ball axle sleeve 11 and hold up by test agent 4, hold up 50 millimeters of height; When cam 14 forwards to over Fig. 1 position (peak of cam), push rod head 13 breaks away from cam 14, under the effect of Compress Spring 12, pallet 2 and push rod 5 fall to rapidly on buffer stopper 10, are also dropped on wood made table top 1 with free-fall velocity by test agent 4 simultaneously, as shown in Figure 2, cam 14 continues rotation, repeats above action, goes round and begins again like this, cam 14 rotation 50 circles can reach to make and be fallen the purpose of 50 times by test agent.
