And it is located at 114 lower section of groove；The height of damper 5 is greater than the height of the first support portion 111 and the second support portion 112；The structure
New reasonable, freely falling body after sliding block 11 is pushed to eminence by linear motor 14 has stronger impact force, first passes through damping
The buffering of device 5, avoids the direct impact in 11 dropping process of sliding block to linear motor, and the height of damper 5 is greater than the first support
The height of portion 111 and the second support portion 112 ensures that sliding block 11 is first damped device 5 and is obstructed；Damper 5 divides for the first damping
Device 51 and the second damper 52 are respectively arranged on the two sides of through-hole, so that two sides uniform force, anti-limited slip block 11 is by damper 5
Deformation damages guide rail 13 in buffering course；113 length of interconnecting piece is less than the length of middle plate 162, when damper 5 damages
When, the first support portion 111 and the second support portion 112 can also support in preventing from directly falling off on middle plate 162 pound damage linear motor
14。
Further, antirust sliding sleeve 3 includes that the first antirust sliding sleeve 31 on 13 outer surface of guide rail and being set to is slided
The second antirust sliding sleeve 32 on the inner surface in hole 115；First antirust sliding sleeve 31 and the second antirust sliding sleeve 32 are hollow circle
Column, 32 internal diameter of the second antirust sliding sleeve are greater than the outer diameter of the first antirust sliding sleeve 31；Antirust sliding sleeve 3 divides to be wrapped in guide rail 13
Upper first antirust sliding sleeve 31 can anti-limited slip block get rusty and the second antirust sliding sleeve 32 on sliding block 11, the first antirust is sliding
Dynamic set 31 and the second antirust sliding sleeve 32 are fitted close mutual cooperation between the two and slide, the novel and reasonable structure and can be effective
The current sliding block 11 of solution and guide rail 13 between by linear bearing carry out cooperation exist generate rusty stain cause equipment operation have some setbacks
Smooth problem.
Further, antirust sliding sleeve 3 is as made by PPR material；The material can effectively realize rust-proof effect, and at
This is lower easy to manufacture and coefficient of friction is lower between the first antirust sliding sleeve 31 and the second antirust sliding sleeve 32 has preferably
Sliding effect.
Further, impact member 12 includes trip rod 121 and the impact bead 122 on trip rod 121, trip rod
121 one end are connected with sliding block 11, and the other end extends outside the vertical chute 21 of cabinet 2；The design is when sliding block 11 is by straight line
When motor 14 pushes, sliding block 11 drives trip rod 121 to move upwards in vertical chute 21, while trip rod 121 also drives and hits
Batting 122, which moves upwards, to be reached up to eminence.
Further, trip rod 121 and sliding block 11 are hinged by shaft 6；The connection type works as impact member 12
After experiencer's collision, there is a movement popped up, so that entire experience is more nearly reality, experiencer head is not
It is pushed down as component 12 is knocked always.
Further, it is connected through a screw thread between trip rod 121 and impact bead 122,122 outer surface of impact bead is arranged with rubber
Gum cover；The connection type can realize that the shock to different weight is experienced by replacing the weight of impact bead 122；Equipped with rubber
Set can make impact bead when hitting safety cap, will not cause to wear to safety cap, have certain buffering effect and make
Impact bead 122 is more beautiful.
Further, it is together by a threaded connection between clump weight 4 and sliding block 11；The connection type, when impact bead 122
When carrying out different weight replacement, clump weight 4, which can also carry out replacing accordingly, ensures that sliding block 11 keeps balance, anti-limited slip block 11
Imbalance causes to deform to guide rail.
Further, first 1 quantity of safety cap impacting body verification certificate is three, and three safety cap impacting body verification certificate members 1 are set side by side
It sets in cabinet 2；The design can enable three experiencers while experience, and can effectively save when experiencer's number is more
Save the waiting time of experiencer.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
