The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1; A kind of synchronous connecting axle; Can use and have the large-scale curtain of parallel double track, ceiling curtain, abat vent etc.; Can drive single motor-driven cord and on a no motor-driven siding track, force to realize synchronous operation, also can be so that the cord of Dual-motors Driving is eliminated the asynchrony phenomenon that causes because of the motor manufacturing variation.

In the utility model, be example with the ceiling curtain, comprise the track 1 that is positioned at both sides, be provided with the belt that transmission is used in the track 1, the end of track 1 is respectively equipped with asynchronous machine 2.The lining 4 of ceiling curtain; Be generally sunshade and use textile; The end of its both sides is fixed on the belt through fixture 41, and the remainder of both sides evenly is provided with pulley 42, when asynchronous machine 2 runnings drive the belt slip; The end of lining 4 is sliding in track 1 under the drive of asynchronous machine 2 and belt, and remainder is sliding through pulley 42 and can in track 1, slide according to end then.

Owing to adopted two asynchronous machines 2, when asynchronous machine 2 runnings, can small asynchrony phenomenon appear the difference owing to making inevitably.Track 1 connection of synchronous connecting axle 3 with both sides is set, realizes forced synchronism, eliminate small difference through mechanical system.Referring to Fig. 2, Fig. 3 and Fig. 4; Connecting axle 3 comprises connection main shaft 21 synchronously, and the end of track 1 is connected with end cap 11, and the end cap 11 of track 1 one ends is connected with and connects main shaft 21; The end cap 11 of track 1 other end is connected with asynchronous machine 2; Connecting directly heel end lid 11 connections of main shaft 21, also can be that the two ends that connect main shaft 21 are connected with Coupling Shaft 22 respectively, and Coupling Shaft 22 connects end cap 11 more respectively.In order to make that need not to regulate the length that connects main shaft 21 also can normally use, connect the mode that main shaft 21 and Coupling Shaft 22 adopt sockets, be socketed on the Coupling Shaft 22 as connecting main shaft 21.Rotating shaft 221 diameters on the outside of Coupling Shaft 22 increase, and are arranged with jump ring 222 on its end, and are preferred, are the C type, with fixed rotating shaft 221.End cap 11 comprises interconnected drive end bearing bracket 12 and rear end cap 13, and rotating shaft 221 is passed the centre bore 235 of rear end cap 13 and located, and cooperates with drive end bearing bracket 12 interior gears 111.Be symmetrically arranged with the first arc bulge loop 223 on the outside, bottom surface of rotating shaft 221; Accordingly, being symmetrically arranged with the second arc bulge loop, 112, the first arc bulge loops 223 and the second arc bulge loop 112 on the inside bottom surface of gear 111 works in coordination; Form a full circle, and belt is arranged on the gear 111.Thus, when belt driven gear 111 rotated, gear 111 can drive turning cylinder 22 and rotate, thereby through connecting the turning cylinder 22 that main shaft 21 is delivered to opposite side, forced to realize being synchronized with the movement of two side gears and belt.

Installing for ease, rear end cap 13 adopts hasp type to be connected with drive end bearing bracket 12.Rear end cap 13 is provided with hasp 231 near a side of lining 4; Be installed in the rear end cap 13 through torsion spring 232 and location Coupling Shaft 233; Be symmetrically arranged with the first arc ring 234 that extends radially outwardly from centre bore 235 on the outer circumference of the centre bore 235 of rear end cap 13, the corresponding position, installing hole 113 position of the inboard of drive end bearing bracket 12 is symmetrically arranged with the second arc ring 114 that extends internally from outer periphery.During installation, the second arc ring 114 is positioned at first arc ring 234 outside radially, its medial surface and the first arc ring 234 lateral surface butt radially radially, thus prevent that rear end cap 13 from moving up and down.Hasp 231 places under the active force of torsion spring 232 in the breach 115 of drive end bearing bracket 12 1 sides, does side-to-side movement to prevent rear end cap 13.When needs are dismantled synchronous connecting axle, only need rotation hasp 231 to leave breach 115 and get final product.

The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection domain of the utility model.
