Embodiment
Further understand and understanding for making structure characteristic of the present invention and the effect reached had, cooperate detailed explanation, be described as follows in order to preferred embodiment and accompanying drawing:
The present invention is exactly the position structure form with special novelty, can utilize general machining mode, constitutes unlimited multilayer sleeve mechanical positioning mode, realizes pinpoint effect in bigger stroke range.In conjunction with the characteristic of flexible cable traction, the flexible drawing rope is hidden in the central authorities of multilayer sleeve, make that application apparatus integral body is small and exquisite, the perfect General of extension outline of an impression, its main application form is referring to Fig. 1.
Fig. 1 is the structural drawing that multilayer sleeve of the present invention cooperates flexible cable traction vertical lift device, comprises multilayer sleeve 1, flexible cable 2 and traction power 3.Traction power 3 drives the flexible cable 2 that is fixed on the multilayer sleeve 1, so cooperates the flexible cable haulage gear when changing object height, and the spatial attitude of object is all remained unchanged at any height.Fig. 2 is the condensed state figure of Fig. 1.
Multilayer sleeve structure of the present invention mainly is made up of inner tube 4, slide block 5, external pipe 8 and pipe clamp 9.Inner tube 4 and external pipe 8 cooperatively interact, between inner tube 4 and the external pipe 8 and keep identical gap.
Fig. 3 is the sectional view of inner tube of the present invention and slide block combination, as shown in the figure.The basic shape in body cross section is roughly square.The middle part of four faces of inner tube 4 inwalls is provided with first groove 7 that cooperates slide block 5 location, and the middle part of four faces of inner tube 4 outer walls is provided with first flange 6 that cooperates pipe clamp 9 location, and slide block 5 is fixed on first flange 6 of inner tube 4 upper end outer walls.
Fig. 4 is the sectional view of external pipe of the present invention and pipe clamp combination, as shown in the figure.Pipe clamp 9 is fixed on second flange 10 of external pipe 8 lower end inwalls, and 9 liang of pawls of pipe clamp pass through tube wall.
Fig. 5 is four face slide blocks and groove fit localized cross-sectional figure, and Fig. 6 is that the four sides pipe clamp cooperates localized cross-sectional figure with flange, as shown in the figure.Inner tube 4 and external pipe 8 cooperatively interact, the slide block 5 of inner tube 4 upper end outer walls slides (as shown in Figure 5) along second groove, 11 both sides of external pipe 8 inwalls, the pipe clamp 9 of external pipe 8 lower end outer walls penetrates tube wall and is buckled in inner tube 4 first flange, 6 both sides, upper end (as shown in Figure 6), Fig. 5, position structure shown in Figure 6 form a single shaft direction position constraint, and four faces act on simultaneously.And from localized cross-sectional, one group of slide block of opposing parallel face can retrain the degree of depth that cooperates of slide block with the groove of vertical with it two faces in addition, four slide blocks can be finished slide block and the constraint of groove both sides separately, the degree of depth constraint that can cooperatively interact again and finish slide block and groove, make the slide block front contact never, slide mutually and have only the contact of bi-side with the groove front.
In like manner, the locating flange of the pipe clamp of external pipe lower end and inner tube outer wall constitutes four face synchronization constrains, and pipe clamp only contacts the bi-side of flange.The internal and external layer sleeve pipe constitutes two localized cross-sectional (slide block localized cross-sectional 12 and pipe clamp localized cross-sectional 13), reaches the internal and external layer sleeve pipe when sliding mutually, keeps good coaxial nature and the characteristic of deviation (as shown in Figure 7) without spin.
In addition, in actual applications, also must above inner tube 4, four limiting stoppers 14 (as shown in Figure 7) be set apart from upper end module 5 specific range positions, limiting stopper 14 is similar to 5 functions of upper end slide block, just its width is less than upper end slide block 5, its effect is that (Fig. 7 is not expression temporarily with positioning block, this positioning block is used for the location of body toward lower slider, be arranged at the position of inner tube below) apart from upper end limiting stopper 14 specific ranges, touch with external pipe 8 lower end pipe clamps 9 and to be the slip terminal point, control internal and external layer pipe (4,8) minimum orientation distance, guarantee rational axis Location accuracy, any contact do not take place with external pipe 8 inwalls in limiting stopper 14, do not increase any surface friction drag.
Above-mentioned inner tube has identical profile nature with external pipe, that is to say outer wall device slide block and limiting stopper, can possess the characteristic of inner tube, same outer wall device pipe clamp in the inner tube lower end in the external pipe upper end, the characteristic that can possess external pipe constitutes the multilayer tubing shrinking structure successively.
And the cooperation of inner tube and external pipe can be expanded arbitrarily, Fig. 7 is the enforcement illustration that the present invention's two sleeve pipes cooperate, but the present invention is not limited to this, preferential embodiment of the present invention is a 4-8 sleeve pipe fit form, and it is also the most with practical value, make that the collocation of minimum tube boundary dimension and largest tube boundary dimension is the most attractive in appearance, coordinate the most.Determine that simultaneously the sleeve pipe specification of optimizing the most is respectively (neat size outside the cross section): 70X70mm, 80X80mm, 90X90mm, 100X100mm, 110X110mm, 120X120mm, 130X130mm, 140X140mm, shell clearance are 1.2-1.5mm.
With 6 sleeve pipes is application example, and the length of every pipe is 800mm, and two point locations distance is 200mm (1/4 lap of pipe range), and the effective height of pipe clamp is 12mm, and outermost tubes is a fixed tube, and the every pipe of all the other 5 pipes stretches out and is 600mm.6 sleeve pipe total heights are 848mm (minimum tube can be fully retracted) when all shrinking; Total height is 3800mm when all stretching out; Lifting travel can reach 2952mm; Magnification reaches 1: 4.48 (shrinking total height: stretch out total height entirely).
Multilayer sleeve shrinking structure of the present invention, its body material is the aluminium alloy section surface oxidation processes, slide block and pipe clamp material are acetal plastic, its fiting effect is minimum force of sliding friction, minimum friction material loss, the rubbing surface that adds the upper sectional material exposed parts is comparatively hidden, and long-term use can guarantee stable Location accuracy, can guarantee that again the body outward appearance do not have obvious scratch.
In sum, it only is preferred embodiment of the present invention, be not to be used for limiting scope of the invention process, all equalizations of doing according to the described shape of claim scope of the present invention, structure, feature and spirit change and modify, and all should be included in the claim scope of the present invention.
