Abstract
The utility model relates to a slow down and roll up curtain device, including end cover, axle sleeve, fixed dabber, pearl rope sheave, its characterized in that: the axial of pearl rope sheave side is equipped with and keeps off the lid, and the outer edge that keeps off the lid closely cooperates with the end cover periphery, keep off covering and go into the groove along radially being equipped with the pearl cable loop, such structure, the pearl rope install and remove simple and convenient, to roll up smooth and easy, the whole degree of closely cooperating of putting good, have laborsaving smooth and easy, advantage that the noise waited less, but wide application in sunshade, the decoration of occasions such as official working, house or hospital.
Description
Technical field
The utility model relates to the technical field of decoration, sun-shading blind device, particularly using pearl rope as the deceleration roller blind device of rolling power.
Background technology
At present, in traditional roller shutter or abat vent product, comparatively succinct as the roller blind device structure of rolling power using pearl rope, relative inexpensiveness, still has the larger market space.But in actual use, the pearl rope sheave major part affected due to pearl rope exposes, and the sideline on cord or the end of a thread can be let slip in journey at volume and be wrapped on pearl rope sheave, uneven about causing cord to be rolled up when putting, about cord, volume is put inconsistent, has had a strong impact on the Integral decoration effect of cord.For this FAQs, the structure of improvement is had to be that one door is set on pearl rope sheave surface, by door, pearl rope sheave is covered, but such structure increases the thickness of roller blind device on the one hand, pearl rope is caused again to import when pearl rope sheave is installed on the other hand cumbersome, need to reserve larger gap in the cooperation place of door and roller blind device, otherwise, pearl rope is difficult to import pearl rope sheave, if but reserved excesssive gap, but convenient cannot overcome sideline completely or the end of a thread is involved in, is wound around the problem of pearl rope sheave although import, make the impression of user not good.Therefore, be necessary to carry out technological improvement to current roller blind device product.
Utility model content
The purpose of this utility model is the weak point overcoming above-mentioned conventional art, proposes that the mounting or dismounting of a kind of pearl rope are easy, volume puts forward smooth, entirety and to closely cooperate the good deceleration roller blind device of degree.
The purpose of this utility model is achieved by the following technical solution: deceleration roller blind device, includes end cap, axle sleeve, fixed central spindle, pearl rope sheave; It is characterized in that: the axial sides of pearl rope sheave is provided with door, the outer of door coordinates with end cap perimetral tight, door is radially provided with pearl sling and enters groove.
Further, be simplify structure, strengthen intensity, described door and pearl rope sheave one-body molded, it is the step trough that front end is little, rear portion is large that its pearl sling enters groove shape.For making volume put lightly smoothly, the inwall of described pearl rope sheave is provided with inner circular tooth, and inner circular tooth engages with each under drive gear on axle sleeve, engages inside each under drive gear with the centre tooth in fixed central spindle again.The pearl sling that door is disposed radially enters groove to be had multiple, is uniformly distributed.
Such structure, has obvious advantage: the pearl rope 1, manually pulled enters groove by pearl sling and is arranged on pearl rope sheave easily.2, tightly coordinate between door with end cap, gap is superfine, and the sideline of curtain body or the end of a thread can be avoided completely to be involved in pearl rope sheave, and protective is good by mistake.3, use volume to keep steady, smoothly, noise is few.

Description of reference numerals: 1 end cap 2 fixed central spindle 21 centre tooth 3 pearl rope sheave 31 door 32 buckles into groove 33 inner circular tooth 4 reduction gearing 5 axle sleeve 6 spindle nose.
Detailed description of the invention
The deceleration roller blind device of the present embodiment is mainly supporting for household, indoor abat vent or decorative curtain.Wherein, roller shutter body adopts conventional planar materials, and as cord, and main shaft and energy-storaging spring device thereof are routine techniques, and the core of this patent is being loaded on the deceleration roller blind device at main shaft two ends.
See Fig. 1 and Fig. 2, deceleration roller blind device includes the end cap 1 as matrix, also fixes with it the fixed central spindle 2 of assembling through end cap 1, passes fixed central spindle 2 and the pearl rope sheave 3 that be rotatably assorted corresponding to end cap 1 from the other end, axle sleeve 5 is set in fixed central spindle 2, and axle sleeve 5 is outer is plugged with spindle nose 6 again.
Wherein, pearl rope sheave 3 axial sides disjunctor forms door 31, and the outer of door 31 coordinates with end cap 1 perimetral tight, door 31 is radially provided with pearl sling and enters groove 32, and it is the step trough that front end is little, rear portion is large that pearl sling enters groove 32 shape.The inwall of pearl rope sheave 3 is provided with inner circular tooth 33, and axle sleeve 5 bottom is provided with 5-7 deceleration transmission tooth 4, and each deceleration transmission tooth 4 periphery is engaged with inner circular tooth 33.Central authorities of fixed central spindle 2 are provided with centre tooth 21, and each deceleration transmission tooth 4 inner circumferential engages with centre tooth 21.Like this, when pearl rope sheave 3 rotates, its inner circular tooth 33 drives each deceleration transmission tooth 4 to rotate, and deceleration transmission tooth 4 drives axle sleeve 5 to rotate, thus spindle nose 6 is rotated in deceleration.
The course of work: pearl rope sheave 3 rotates, its inner circular tooth 33 rotates, and drives each deceleration transmission tooth 4, and each deceleration transmission tooth 4 drives axle sleeve 5 to rotate, and axle sleeve 5 drives spindle nose 6, spindle nose 6 drive shaft (in figure, main shaft does not draw).
Realize pearl rope sheave 3 to rotate, then need by pearl rope (not shown in FIG.), the transmission pearl on pearl rope coordinates with pearl rope sheave 3.And realize pearl sling and enter pearl rope sheave 3, then that pearl sling by door 31 is radially set up enters groove 32, first pearl sling is entered the arc-shaped side incision (as shown in Figure 1 position) that groove 32 dials to end cap 1, pearl sling is entered after pearl sling enters groove 32, pull pearl rope, pearl rope sheave 3 rotates, and the transmission pearl on pearl rope is just taken advantage of a situation and buckles in pearl rope sheave 3 one by one, around a circle, just complete wearing of pearl rope and buckle.Reverse operation, then can exit pearl rope from pearl rope sheave 3.Because door 31 outer of pearl rope sheave 3 and end cap 1 closely cooperate, can play and well airtightly block effect, so the sideline at curtain body edge or the end of a thread can not be wound, be involved in pearl rope sheave 3, thus effectively avoid interference, ensure that roller blind device volume is put steady, smooth and easy.
Certainly, only enumerate some preferably embodiments here, the technical program can do other equivalent or roughly the same change, repeat no more here, but they should belong to the protection domain of this patent.
