Abstract
A kind of reinforcement belt pulley, the accessory that relates to sunshade roll-up window, comprise belt pulley housing and output shaft, belt pulley housing is arranged on output shaft by jump ring, and around output shaft rotation, floor installation groove is set on belt pulley housing, a circle belt pulley gear is set on the belt pulley housing in floor installation groove, one circle output shaft gear is set on output shaft, and output shaft gear is arranged in floor installation groove; Annular base is also set in floor installation groove, on base, be wholely set back shaft, duplicate gear is set on back shaft, duplicate gear prevents that by upper cover duplicate gear from axially moving, the canine tooth of duplicate gear is meshed with belt pulley gear, and the little tooth of duplicate gear is meshed with output shaft gear; The first blowout patche is set between output shaft and base, between output shaft and belt pulley housing, the second blowout patche is set.Engagement by large small gear is rotated, and according to gear, meshes deceleration increment principle, thereby realizes the reduction of external roller blind steering force, improves the convenience of user's operation.
Description
Technical field
The utility model relates to the accessory of sunshade roll-up window, relates in particular to the structure of the belt pulley that drives the lifting of curtain sheet.
Background technique
The belt pulley of generally applying on aluminum current alloy external roller blind, for general plastic construction, by manual or electronic drive unit, drive, thereby realize, drive anistree tubular axis to rotate the lifting of external sunshade, run into the window that size is larger, drive the required steering force can be very large, be unfavorable for user's operation, may cause that user operates discontented.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of reinforcement belt pulley is provided, and by gear, meshes, and realizes deceleration increment, reduces the use steering force of external roller blind.
The purpose of this utility model is achieved in that a kind of reinforcement belt pulley, comprise belt pulley housing and output shaft, described belt pulley housing is arranged on output shaft by jump ring, and around output shaft rotation, floor installation groove is set on belt pulley housing, one circle belt pulley gear is set on the belt pulley housing in floor installation groove, a circle output shaft gear is set on output shaft, output shaft gear is arranged in floor installation groove; In described floor installation groove, annular base is also set, on base, be wholely set back shaft, back shaft and output shaft be arranged in parallel, duplicate gear is set on back shaft, duplicate gear prevents that by upper cover duplicate gear from axially moving, the canine tooth of duplicate gear is meshed with belt pulley gear, and the little tooth of duplicate gear is meshed with output shaft gear; The first blowout patche is set between described output shaft and base, between output shaft and belt pulley housing, the second blowout patche is set.
Back shaft on base of the present utility model has four, duplicate gear has four, each duplicate gear is arranged on respectively on corresponding back shaft, and the canine tooth of each duplicate gear is meshed with belt pulley gear respectively, and the little tooth of each duplicate gear is meshed with output shaft gear respectively.
The beneficial effects of the utility model are: by the drive of drive unit, the canine tooth engagement of four duplicate gears of all cloth of belt pulley gear and base portion realizes rotates, the little tooth of four duplicate gears and output shaft gear are realized engagement simultaneously, engagement by large small gear is rotated, according to gear engagement deceleration increment principle, thereby realize the reduction of external roller blind steering force, improve the convenience of user's operation.Four gears of all cloth mesh simultaneously simultaneously, effectively reduce the power that each gear bears, and reduce the mechanical property requirements of gear material, have improved system reliability.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, be reinforcement belt pulley, comprise belt pulley housing 1 and output shaft 3, belt pulley housing 1 is fixed on output shaft 3 by jump ring 2, and rotates around output shaft 3.Floor installation groove 9 is set on belt pulley housing 1, a circle belt pulley gear 1-1 is set on the belt pulley housing 1 in floor installation groove 9, a circle output shaft gear 3-1 is set on output shaft 3, output shaft gear 3-1 is arranged in floor installation groove 9.Annular base 10 is also set in floor installation groove 9, on base 10, be wholely set four back shafts 5, every back shaft 5 be arranged in parallel with output shaft 3 respectively, on every back shaft 5, duplicate gear 4 is set respectively, each duplicate gear 4 prevents that by upper cover 6 duplicate gear 4 from moving axially respectively, the canine tooth 4-1 of each duplicate gear 4 is meshed with belt pulley gear 1-1 respectively, and the little tooth 4-2 of each duplicate gear 4 is meshed with output shaft gear 3-1 respectively.The first blowout patche 7 is set between output shaft 3 and base 10, the second blowout patche 8 is set between output shaft 3 and belt pulley housing 1.
By the drive of drive unit, the canine tooth 4-1 engagement of four duplicate gears 4 on belt pulley gear 1-1 and base 10 realizes rotates, simultaneously the little tooth 4-2 of four duplicate gears 4 realizes and meshing with output shaft gear 3-1, and output shaft 3 is fixed on by the first blowout patche 7 and the second blowout patche 8 in the center hole of base 5 and belt pulley housing 1 and rotates.Meshing parameter by two-stage gear designs, and realizing slows down increases the effect of square.
