Embodiment
Address other technology contents, characteristics and effect about before the present invention, in the detailed description of following cooperation two preferred embodiments with reference to the accompanying drawings, can know to present.
Before the present invention is described in detail, be noted that in the following description content similarly member is to represent with identical numbering.
Fig. 2 a is the installation diagram of a preferred embodiment of the present invention.Shown in Fig. 2 a, a preferred embodiment of the present invention, this embodiment has disclosed a mandrel rod damping structure 400, and this mandrel rod damping structure 400 mainly includes a housing 10, and a packing member 12.This wherein, packing member 12 is connected on the housing 10 by screw or rivet, and is forced to fasten the mandrel rod 200 that has been installed on this housing 10.
Need to prove, below only be connected to example with screw, it is replaced into rivet and connects and belong to that those skilled in the art expect easily, so repeat no more.
In simple terms, when mandrel rod 200 was supported by the v-shaped structure on this housing 10, this v-shaped structure formed point with mandrel rod 200 and contacts, and can control the positional precision of mandrel rod 200 better.In order to make packing member 12 more compress mandrel rod 200, apply utilization at the elastic component 13 that utilizes 12 pairs of rubber materials of packing member, closely touch mandrel rod 200 to force elastic component 13, make mandrel rod 200 remain no gap state.Thus, so just can solve the fit-up gap because of mandrel rod 200 effectively, the elastic component 13 of this rubber material can also absorbing vibration simultaneously.This structure can solve the many vibrations on the mandrel rod circumferencial direction, scanning module skew in the scanning process can not occur, and the multiple image problem that causes has also reduced the generation of noise simultaneously.Under, the combination and the relevance of housing 10, packing member 12 and mandrel rod 200 more specifically are described.
See also Fig. 2 b～Fig. 2 d, offer an installation axle hole 101 on the housing 10, part structure that is in the shape of the letter V of its carrying mandrel rod makes the mandrel rod 200 that has been mounted form with it a little and contacts.In addition, the part that contacts with V font structure of this mandrel rod 200 is an annular groove 201, and this groove is stuck on this v-shaped structure, and can suppress mandrel rod 200 moving in the axial direction.On housing 10, also offer first installing hole 103 and restriction jack 102.First installing hole 103 and restriction jack 102 are in respectively on the symmetrical position.One packing member 12 is made by a rigid material.
Please in conjunction with consulting Fig. 2 c, offer second installing hole 121 on the connecting portion 102 of this packing member 12, its position is corresponding with first installing hole 103.When screw 122 passes second installing hole 121, first installing hole 103 and is tightened, to fix this packing member 12 on housing 10.The both sides of packing member 12 connecting portions are connected with limited 123, and this limited 123 is the inserted sheet shape, can be inserted in this restriction cutting 102, to limit this position of packing member 12 on housing 10.Lower end position at connecting portion 120 is connected with a clamping part 124, and it is one plane that this clamping part 124 is.Also has an elastic component 13 between this clamping part 124 and the mandrel rod 200.Preferably, this elastic component 13 is the member of a rubber material.When utilizing packing member 12 to compress mandrel rod 200, if between be equipped with the elastic component 13 of rubber material can shock-absorbing, to reduce vibrations.
V font structure contacts with 200 of mandrel rods, and the compressing of 12 pairs of mandrel rods 200 of packing member, and makes to contact for no gap between mandrel rod 200 and the housing 10; The shock-absorbing of rubber material is arranged again, can suppress the vibrations that cause by revolution influence like this, the vibrations on the circumferential direction that is suppressed at mandrel rod 12 that especially can be good mandrel rod 200 stability.Simultaneously, owing to be gapless contact.Can reduce touching between mandrel rod 200 and the housing 10, reduce noise.
The above only is preferred embodiment of the present invention, when not limiting scope of the invention process with this, promptly the simple equivalent of being done according to the present patent application claim and invention description content generally changes and modifies, and all still belongs in the scope that patent of the present invention contains.Arbitrary embodiment of the present invention in addition or claim must not reached the disclosed whole purposes of the present invention or advantage or characteristics.In addition, summary part and title only are the usefulness that is used for assisting the patent search, are not to be used for limiting protection scope of the present invention.
