On shipping platform 23, mounting means are as follows: the fast locking device of double thread is screwed into the spiral shell on vibration isolation shipping platform 23 by threaded post 17
Kong Zhong, and it is not exposed to the load plane 25 where elastomer 24.When equipment conveying, supported by elastomer 24 come vibration isolation
And shock resistance needs vibration isolation shipping platform 23 to support and lock, it is necessary to which double thread through the invention is locked fastly when parking
Device is realized.It needs to rotate clockwise operation handle 1 first, because straight pin 2 is stuck in guide groove 13, rotation process handle
It can make screw rod 5 and stud 4 when 1 while rotate, after threaded post 17 screws, the lower end surface of stud 4 is resisted where elastomer 24
Carrying platform 25 on, thus replace elastomer 24 to vibration isolation shipping platform 23 provide support.In addition, by using knurled head
15 can also quickly rotate stud 4.It is provided with escape 16 outside stud 4 simultaneously, end face positioning can be carried out, to ensure stud 4
Bearing height it is consistent.After the completion of support, operation handle 1 is compressed downwards, and straight pin 2 can be made to be detached from guide groove 13 downwards, this
When screw rod 5 can individually rotate.Continue to rotate clockwise operation handle 1, straight pin 2 can rotate not in limit hole 19 at this time
It will receive blocking, threaded rod 12 can be across 22 bottom of unthreaded hole in rotary course, and is screwed into the carrying where elastomer 24
In the screw hole of plane 25, stud 4 can be locked on load plane 25 after screwing, and then realize vibration isolation shipping platform 23 and hold
Carry the locking between plane 25.Wherein pilot hole 20 can guarantee screw rod 5 in independent rotation with 4 concentric co-axial of stud, and spiral shell
Pressing plate 8 and 4 upper end cross section of stud on bar 5 are in close contact, and can play the role of limiting the up and down motion of stud 4, Neng Gouqi
To the effect of secured locking vibration isolation shipping platform 23.When needing to be detached from locking and support, rotation process handle 1 counterclockwise is
It can.
