Usefulness of the present invention is: fixture is inserted respectively in the placed cavity of pedestal, as long as slight choosingAfter rotation is fixing, can carry out synchronous stretching to multiple fixtures by screw, make multiple fixtures simultaneouslyBe fixedly connected with pedestal, fix so quick and convenient. Elastic component makes this connection more firm.
Brief description of the drawings
Fig. 1 is the structural representation of a preferred embodiment of the present invention.
The implication of Reference numeral in figure:
1-pedestal, 2-fixture, 21-slip cylinder, 211-the first cylinder, 212-the first cylinder, 22-elasticityPart, 23-retainer ring, 3-tensioning member, 31-connecting portion, 32-draught line, 33-screw.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
As shown in Figure 1, pedestal fixed structure, comprising: pedestal 1 and the fixture 2 that is positioned at pedestal, GuDetermining part 2 comprises: slip cylinder 21, the elastic component 22 that is positioned at slip cylinder 21 outsides and retainer ring 23; SlidingMoving cylinder 21 is made up of two different cylinders of bottom surface radius, the dead in line of two cylinders; Bottom surface radiusLittle cylinder is the first cylinder 211, and the cylinder that bottom surface radius is larger is the second cylinder 212; Elastic component 22 HesRetainer ring 23 is positioned at the periphery of the first cylinder 211; Elastic component 22 is fixedly connected with retainer ring 23; Pedestal 1Be provided with the placed cavity that holds fixture, in placed cavity, be provided with the tensioning member 3 being connected with fixture 2, tensioning member 3Comprise: the connecting portion 31 being connected with retainer ring 23, the draught line 32 of stretching connecting portion 31, with draught line 32The screw 33 connecting; Screw 33 is rotatably connected with pedestal 1.
Elastic component 22 is positioned at one end near the second cylinder 212 of the first cylinder 211, and retainer ring 23 is positioned atOne end away from the second cylinder 212 of the first cylinder 211. The first cylinder 211 outsides are provided with external screw thread, outerScrew thread is positioned at the outside of the first cylinder 211 away from one end of the second cylinder 212, and connecting portion 31 is provided with and outer spiral shellThe internal thread of line coupling, the middle part of connecting portion 31 is provided with groove, and internal thread is positioned at the inner side of groove. And,The first cylinder 211 tall and big in the axial length sum of elastic component 22 and retainer ring 23, while installation like this,The first cylinder 211 inserts in groove, the screw-internal thread fit of the external screw thread of the first cylinder 211 and groove inner side,The first cylinder 211 is fixedly connected with tensioning member 3. Retainer ring 23 is fixedly connected with pedestal 1 by screw thread.
In the time needing the three-jaw of fixed optics instrument base, by the first cylinder of the slip cylinder 21 of fixture 2211 insert in the placed cavity of pedestal down, and fixture 2 is fixedly connected with tensioning member 3, meanwhile, fixingRing 23 is fixedly connected with pedestal by screw thread; Then rotating screw 33, by the traction being connected with screw 33Line 32 drives tensioning member 3 to the direction motion away from the second cylinder 212, and tensioning member 3 drives the first cylinder 211Downwards, because the semidiameter of the first cylinder 211 and the second cylinder 212, the first cylinder 211 is to elastic component 22Produce pressure, make elastic component 22 outwardly convexs, increase the friction of itself and placed cavity inwall, make the two tightClose fixing.
As a kind of preferred version, the rubber that connecting portion 31 is annular, rubber is durable flexible, rubberPreferably 1.5～3mm of the thickness of glue, the too thick difficult generation deformation of rubber, rubber is too thin fragile, therefore first-selectedThickness is 2mm. Draught line 32 is carbon fiber draught line, and the light intensity of carbon fiber quality is large.
More than show and described general principle of the present invention, principal character and advantage. The technology people of the industryMember should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or equivalence changeThe technical scheme that the mode of changing obtains, all drops in protection scope of the present invention.
