The specific embodiment

In order more to understand characteristics of the present utility model, lift three preferred embodiments and conjunction with figs. and be described as follows:

See also Fig. 1, Fig. 2, the relocation mechanism 10 that the utility model first preferred embodiment is provided is provided in a side of on the substrate 12, the function of the carrying of floating is provided, base is pulled 12 and is included an end face 13, one bottom surface 14, and a garden shape perforation 15 perforation end faces 13 and bottom surface 14, relocation mechanism then includes a float plate 20, one replaces assembly 16, and three elastic components 24.

Float plate 20 is replaced assembly 16 to replace and be positioned at substrate 12 tops, is extended with a center pillar 21 under float plate 20 mediads to be arranged in the substrate twelve punch 15, and the bottom of center pillar 21 then is stretched on the bottom surface 14 of substrate 12 via perforation 15.

Replacing assembly 16 is to include three balls 17, and three ball base 18 be located at substrate 12 end faces, use respectively for ball 17 and be provided with, ball base 18 (with ball 17) is positioned to be gone up and is distributed in equally spacedly around the perforation 15 in same garden week, and ball 17 can rotate freely in ball base 18, thus, ball 17 borrows ball base 18 to be located at substrate 12 end faces 13 and to be resisted against float plate 20, make between float plate 20 and the substrate 12 and leave a preset space length, the structure of ball and ball base belongs to prior art herein, non-the utility model emphasis, appearance repeats no more.

Elastic component 24 is to be connected with center pillar 21 with its first end 25 respectively, and be connected with the bottom surface 14 of substrate 12 with its second end 26, during actual the manufacturing, three connectors 28 can be set in the bottom surface 14 of substrate 12, establish in order to connect, elastic component 24 can be connected with substrate 12 bottom surfaces 14 by connector 28 for second end 26 of elastic component 24.

Because the bearing of trend of elastic component 24 is to be 120 degree in twos, the center pillar 21 that can see through with joint efforts of three elastic components 24 makes float plate 20 keep center position, when the operator places an object 29 on the float plate 20, object 29 does not contact with substrate 12, therefore, utilizing a driving mechanism (figure do not show) to order about object 29 moves when positioning, driving mechanism will overcome the elastic force of elastic component 24, make object 29 move (do not have relative motion between object 29 and the float plate 20 this moment) with float plate 20, point-like contacts and ball 17 can freely roll in ball base 18 because float plate 20 only forms with ball 17, when moving, object 29 will can not produce dust, can keep the air cleaning in the dust free room, effectively improve the disappearance of existing structure, thereby reach the purpose of this utility model.

In addition, as long as center pillar 21 does not touch perforation 15 peripheries, float plate 20 can be towards any direction displacement, and when object 29 moves apart relocation mechanism 10, float plate 20 will be acted on by elastic component 24 and reply original position, and will be very convenient in the use.

During actual the manufacturing, the setting of ball has multiple variation, as shown in Figure 3, a plurality of balls 30 can be arranged in the ring-type ball base 32, make ball 30 around perforation 34, can reach the purpose of replacing float plate 36, the quantity of right ball needs three at least, 3 of causes could form a plane, and float plate 36 can be replaced reposefully; In addition, the quantity of elastic component and position also can have multiple variation, as long as making a concerted effort of each elastic component is zero and position that float plate 36 maintenances are hit exactly, right minimum two elastic components should be set, as shown in Figure 3, this moment, two elastic components 38 were on same straight line, and no matter float plate 36 is mobile towards where, all can be subjected to the opposite elastic force effect of a direction and homing.

What deserves to be mentioned is that in addition relocation mechanism 10 provided by the present invention can be provided with several on a board, support and unsteady effect that common situation is that four relocation mechanisms 10 are set on a board, in order to carry four jiaos an of object to provide more stably.

The relocation mechanism 40 that the utility model the 3rd preferred embodiment is provided is roughly the same with aforementioned two embodiment, as Fig. 4, shown in Figure 5, also being located at one has on the substrate 42 of perforation 41, and include a float plate 43, one replaces assembly 48 and three elastic components 60, wherein, float plate 43 is also replaced assembly 48 and is replaced and be located at substrate 42 tops, float to pull and be extended with a center pillar 44 under 43 mediads and be arranged in the perforation 41, institute's difference be in: replace assembly 48 and include a pedestal 49 and be located in the perforation 41 of substrate 42, pedestal 49 central authorities have an axis hole 50 and wear for center pillar 44, axis hole 50 tops have one first large-diameter portion 51, central authorities then have a minor diameter part 52, between first large-diameter portion 51 and minor diameter part 52, form one first shoulder 53, plurality of balls 54 is located in the ring-

type ball base

55, and 55 of ball bases are located in first large-diameter portion 51 and are resisted against first shoulder 53, and ball 54 is located on the substrate 42 by ball base 55 and pedestal 49; Pedestal 49 axis holes 50 bottoms have one second large-diameter portion 56, between second large-diameter portion 56 and minor diameter part 52, form one second shoulder 57,44 of center pillars more are provided with a positioning disk 45, be provided with a ring-type ball base 58 in second large-diameter portion 56 and be resisted against second shoulder 57, on the ball base 58 and be provided with some rotatable balls 59 and be resisted against positioning disk 45; In addition, center pillar 44 bottoms are provided with a chassis 46, connect in order to first end 61 for elastic component 60, and pedestal 49 bottoms are provided with three connectors 64, establish in order to connect, elastic component 60 can be connected with the bottom surface of substrate 12 by connector 64, pedestal 49 for second end 62 of elastic component 60.

Whereby, when float plate 43 moves, positioning disk 45 will move in the lump, not only have the unsteady carrying effect in the previous embodiment, its action is more steady, and works as the centre-of gravity shift of 43 loaded objects 65 of float plate, or operating personnel are when upwards triggering float plate 43 accidentally, positioning disk 45 will provide the function of clip, make float plate 43 unlikely perk or disengagings, and structural stability is better; And during actual the manufacturing, because float plate 43, replacing assembly 48 is to be combined into one with elastic component 60, all has convenient part when assembling or storage.
