There are recycling bins 7, the recycling bins 7 are connected with the upper surface of pedestal 1.
In addition, the test ball 10 is steel ball.
The course of work and principle: when the device is not used, electromagnet 92 is in off-position, and articulated slab 65 is in limited post 64
Under the action of it is parallel with limited post 64, since two articulated slabs 65 are all placed in parallel, so that test ball 9 is hinged plate 65 in this way and block
It cuts, when needing to do impact resistance test to tempered glass, will be placed at left and right sides of tempered glass in rotating bar 56 first, so
Applying pressure down afterwards makes rotating bar 56 that the elastic force of second spring be overcome to rotate down on annular guide rod 58, at 56 turns of rotating bar
It can touch support plate 54 when dynamic, and then support plate 54 is driven to overcome the elastic force of the first spring 55 in fixed column 55 to moving down
Dynamic, when rotating bar 56 turns to the edge for crossing tempered glass, the external force at this moment applied will all be applied to support plate 54
On, rotating bar 56 under the action of second spring 57 along annular 58 upward sliding of guide rod, and in the position for turning to gag lever post 52
It stops operating when setting, at this moment stops applying external force, drive support plate 54 and tempering glass in the case where the first spring 55 upsprings power effect
Glass moves up, and when being moved to tempered glass and touching rotating bar 56, stops movement, at this moment tempered glass is in the first spring 55
Under the action of it is fixed, then start cylinder 3 drive protective cover 4 move down, cylinder 3 starting before, first start motor 98,
So that arched plate 94 is turned to vertex position, motor 98 is then made to stop operating, vertical bar 93, which will be in, at this time overcomes the 4th spring
In the state of 99, in addition, upper conducting block 912 and lower conducting block 913 are in close contact under the action of the 5th spring 911 at this time, make
Electromagnet 92 obtains electric generation magnetic force and has attracted test ball 10, and then cylinder 3 starts again, since spill spin block 67 by straight-bar 68 and is protected
Shield 4 connects and spill spin block 67 is threadedly coupled with lower round tube 610, in this way in 4 folding process of protective cover, it will drives lower round tube
610 move down, and positioning column 66 is guaranteed after lower round tube 610 moves down, between will not generating between lower round tube 610 and upper round tube 61
Gap will will drive lower hinge bar 621 by jacking block 623 in 610 folding process of lower round tube and move down, and lower hinge bar 621 passes through company
Extension bar 620 drives upper hinge bar 618 to move down, and will will drive interlocking bar 624 when upper hinge bar 618 is mobile and pass through fixing axle 625
Steering-effecting be rotated up articulated slab 64 around hinge joint, and then open rectangular channel 62 channel, make rectangular channel 62 in
Heart hole 612 is connected, and may cause the gap between the lower end and tempered glass of lower round tube 610 due to the thickness difference of tempered glass
Difference is that guarantee test ball 10 will not be by between the lower end and tempered glass of lower round tube 610 during falling impacts
Gap off center hole 612 can be by rotating spill spin block 67, in the guiding role of guide pad 614 when steel protects thickness of glass difference
Under make the fine tuning up and down in guide groove 613 of lower round tube 610, motor 98 is again started up after the completion, when arched plate 94 turn to it is solid
When determining the edge of block 95 and being detached from, 93 slide downward of vertical bar is driven rapidly under the action of the 4th spring 99, in vertical bar 93 to downslide
During dynamic, vertical bar 93 downslide for the previous period on the one hand since the initial velocity of test ball 10 will be given constantly to accelerate,
On the other hand since the effect of the 5th spring 911, upper conducting block 910 are still connect with lower conducting block 912, electromagnet 92 still leads to
Electricity, when vertical bar 93 continues to glide, upper conducting block 910 is disconnected with lower conducting block 912, and 92 power loss of electromagnet, test ball 9 is obtaining
After initial velocity, the movement of falling object is done downwards along rectangular channel 62 and centre bore 612 under the effect of gravity, then strikes tempering
Glass completes impact resistance test, and arched plate 94 turns to vertex position, upper conducting block 910 and lower conducting block again at this time
912 are again coupled to, and electromagnet 92 is once again powered up, and electromagnet 92 obtains electric attraction test ball 10 again and comes back to original position, in this way in electricity
Magnet 92 is continuous that electric and power loss completes impact resistance test in the process, which is not protected from environmental, and accurate testing is saved
Manpower, if toughened glass crushing, disintegrating slag will be fallen in recycling bins 7, the resistance to punching as required by different tempered glass
The intensity and frequency hit are all different, and frequency of impact can be adjusted by the velocity of rotation of motor 98, and impact-resistant intensity can lead to
The position for overregulating adjusting block 96 keeps the 4th spring 99 elastic force when arched plate 94 turns to vertex position different, exists in this way
Test ball 10 is detached from the initial velocity obtained when electromagnet 92 will be different, and the impact force when reaching tempered glass will in this way
It is different, thus achieve the purpose that the impact resistance requirement for different tempered glass is tested, it is convenient and efficient.
Based on above-mentioned, using a kind of impact resistance testing stand for tempered glass of the invention, needing to tempered glass
When carrying out impact resistance test, tempered glass is suspended vacantly by fixed mechanism first, protective cover then will be driven by cylinder
Tempered glass is covered, prevents the toughened glass crushing in test from splashing being caused to be hurted sb.'s feelings, in cylinder starting, in acceleration mechanism
Arched plate motor drive under move to top to make electromagnet obtain it is electric test ball is sucked, under its protective cover move during open
Articulated slab, after the completion, arched plate continue to rotate, electromagnet power loss after rotation, while test ball is given under the action of four springs
One initial velocity, then test ball, which falls, carries out impact resistance test to tempered glass, electromagnet it is continuous electric and power loss mistake
