Abstract
The utility model relates to a wrapping and winding transmission mechanism for curtains, which comprises a base, a transmission wheel which is connected to the base in movably and a bead chain used for driving the transmission wheel to rotate. The utility model is characterized in that a slot corresponding to the bead chain on the transmission wheel is arranged on the base, and the outer side of the slot, which is positioned on the inner side of the bead chain, is provided with a limit stop. The utility model has the advantage of simple structure. The autorotation of the transmission wheel is realized by the blocking function of the limit stop to the bead chain to prevent the occurrence of the phenomenon that a shaft of the prior art is worn by a spring.
Description
The utility model relates to a kind of coiling transmission mechanism, particularly curtain coiling transmission mechanism.
Existing curtain mainly constitutes in the drive that has axle sleeve 34 on the axle 1, coiling power transmission shaft 5, the turn 6 be located on the axle 1 by having axle 1 pedestal 2, loose joint with winding mechanism, axle sleeve 3 is provided with seam 7 and stretches from stitching 7 with the end that makes things convenient for turn 6, and coiling power transmission shaft 5 inner chambers are provided with block 8.During work, rotate drive 4, drive turn 6 ends of the seam 7 on the axle sleeve 3, because the coiling direction of turn 6 and the direction of rotation of axle sleeve 3, the enlarged-diameter of turn 6 also can be rotated turn 6 around axle 1; Rotate coiling power transmission shaft 5, turn 6 is also along with coiling power transmission shaft 5 rotates, when the coiling direction of the rotation direction of coiling power transmission shaft 5 and turn 6 is opposite, the enlarged-diameter of turn 6, turn 6 also can be along with coiling power transmission shaft 5 rotates, when the coiling direction of the rotation direction of coiling power transmission shaft 5 and turn 6 is identical, and the reduced of turn 6, turn 6 is pressing axle 1 and can not rotate, thereby prevents that the curtain after the package from down falling under the effect of self gravitation.This kind curtain coiling transmission mechanism complex structure; Cause the appearance of skidding during work easily because of turn elastic force deficiency, and after work a period of time, axle 1 is serious wear under the effect of the frictional force of turn 6, thereby the coiling transmission mechanism can not be worked.
Goal of the invention of the present utility model be to provide a kind of simple in structure, the coiling transmission mechanism can be because of the curtain that wearing and tearing damage coiling transmission mechanism.
The utility model is achieved in that and comprises drive on pedestal of pedestal, loose joint, drives the pelletron that drive rotates that its special feature is that the pelletron on corresponding drive on the pedestal is provided with groove, and the outside that is positioned at the groove of pelletron inboard is provided with block.
During use, the pulling pelletron, pelletron drives drive and rotates, drive then drives affixed coiling power transmission shaft thereon and rotates, when stopping drag pelletron, drive rotates under the drive of the curtain after the package, drives pelletron and moves along groove, when pelletron moves to the block place, pelletron is stopped by block and can not move, and drive can not be rotated, until the pulling pelletron, after making pelletron break away from block, drive could rotate.
Compared with the prior art the utility model has advantage of simple structure; Utilize block that the barrier effect of pelletron is realized the drive rotation, the axle that has prevented prior art is by the appearance of the phenomenon that spring wore and tore.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model loam cake;
Fig. 3 is the structural representation of prior art.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the utility model mainly by drive 3 on pedestal 1 of pedestal 1, loose joint, drive the pelletron 4 that drive 3 rotates and constitute, its special feature is that the pelletron 4 on corresponding drive 3 on the pedestal 1 is provided with groove 5, and the outside that is positioned at the groove 5 of pelletron 4 inboards is provided with block 6.
Here, block 6 can be positioned at pedestal 1 under, also can be positioned at the side-lower of pedestal 1.
Pedestal 1 is made of the base 8 that has groove 5, the loam cake 9 that has hole 10, and block 6 can be arranged on the base 8, also can be arranged on the loam cake 9, drive 3 by affixed axle 1 loose joint thereon on the hole 10 of loam cake 9.
Claims (4)
1, a kind of curtain coiling transmission mechanism comprises pedestal, the loose joint drive on pedestal, the pelletron that the drive drive rotates, and it is characterized in that the pelletron on corresponding drive on the pedestal is provided with groove, and the outside that is positioned at the groove of pelletron inboard is provided with block.
2, curtain according to claim 1 coiling transmission mechanism, it is characterized in that block can be positioned at pedestal under, also can be positioned at the side-lower of pedestal.
3, curtain according to claim 1 coiling transmission mechanism is characterized in that block is provided with embedding face.
