Offer for the opening for buckle hanging unit activity；Two slide rails are located in the accommodation space of hollow, and respectively along two projections
Portion reciprocatingly slides；Described buckle hanging unit is stretched out at this opening.
The curtain straight guide of improvement type described in the utility model and groove pulley, wherein, above described straight guide upwards
Extend and outward bending forms the installation groove for coordinating body of wall to install.The design of this installation groove makes recessed above straight guide
Groove is suited with the fixed plate on body of wall, has more stability during installation.
The curtain straight guide of improvement type described in the utility model and groove pulley, wherein, also sheathed in described buckle hanging unit
There is the protection gum cover for preventing pulley when being pulled traveling with straight guide friction.Be so designed that, it is possible to reduce straight guide and
Collision between buckle hanging unit metal and section bar is worn and torn, play cushioning and protection, simultaneously pulley in drawing process not
Straight guide inwall can be brushed up against, reduce friction so that pulley is more smooth in pulling.
The curtain straight guide of improvement type described in the utility model and groove pulley, wherein, described buckle hanging unit bottom also connects
It is connected to the draw ring of 360 ° of rotations.This rotary draw ring makes curtain be more prone in installation process, draws the action of curtain more
Smooth.
The curtain straight guide of improvement type described in the utility model and groove pulley, wherein, at described pulley and connecting shaft
Also it is arranged with bearing.The design of this bearing, in order that pulley can be more freely rotatable in connecting shaft, makes to draw the action of curtain
More smooth.
Implement curtain straight guide and the groove pulley of improvement type of the present utility model, have the advantages that：
(1) groove type design (being different from the wheel of common convex surface) is employed by the wheel portion of pulley, with straight guide
The lobe of lower section matches and is slidably connected, and this structure can make that pulley coupling straight guide is more stable, smooth, and sound is less, draws
It is difficult when dynamic to make pulley and straight guide depart from, there is stability, solve pulley and the easily separated phenomenon coming off of straight guide；This
Outward, the raised track of straight guide is not easy to make dust concentrate in groove so that product is more totally durable；
(2) groove of installing arranging makes the groove above straight guide suit with the fixed plate on body of wall, has more during installation
Stability；
(3) the protection gum cover arranging can reduce the collision between straight guide and buckle hanging unit metal and section bar is worn and torn,
Play cushioning and protection, pulley will not brush up against straight guide inwall in drawing process simultaneously, reduce friction so that pulley exists
More smooth in pulling.

Specific embodiment
Below, in conjunction with accompanying drawing and specific embodiment, this utility model is described further：
As Figure 1-4, a kind of curtain straight guide of improvement type and groove pulley, described groove pulley 2 includes two cunnings
Wheel 21 and pulley mount 22；This pulley mount 22 includes the connecting shaft 221 for installing two pulleys and is used for hanging
The buckle hanging unit 222 of casement；Two pulleys are rotatably mounted around the two ends of connecting shaft respectively；Buckle hanging unit is arranged on connecting shaft
Middle part；Annular groove 211 is provided with each pulley；Described straight guide 1 is the track of hollow, and below straight guide, inner side is convex
It is provided with two and coordinates, with the annular groove on pulley, the lobe 11 slided, offer for supplying buckle hanging unit between two lobe
The opening 12 of activity；Two slide rails are located in the accommodation space of hollow, and reciprocatingly slide respectively along two lobe；Described extension
Buckle stretches out at this opening.
The slide track component of this structure employs groove type design by the wheel portion of pulley and (is different from the wheel of common convex surface
Son), match and be slidably connected with the lobe below straight guide, this structure can make pulley coupling straight guide more stable, pulls
Shi Buyi makes pulley and straight guide depart from, and has stability, solves pulley and the easily separated phenomenon coming off of straight guide；Additionally,
