Abstract

The utility model discloses a guide track for a curtain, which comprises straight tracks. The guide track for the curtain is characterized by further comprising a transition part with certain radian, and the two straight tracks are connected via the transition part. The guide track is convenient for transport, reduces production process and saves cost.

Description

A kind of Rail for curtain

Technical field

The utility model relates to a kind of Rail for curtain, the curved rail that especially a kind of curtain is used.

Background technology

The guide rail that curtain such as existing folding curtain, day fluffy curtain are used, when needing bending curvature, the technology that adopts bending usually with straight guide rail bending to satisfy the demands.

Like Granted publication number is the disclosed a kind of Flexible curtain rail of Chinese patent of CN2392462Y, can accomplish curve track on demand; Disclosed a kind of secondary like Granted publication number with the curtain rail that is prone to curved guide rail for CN2272711Y, can use the handgrip curtain rail crooked, make the guide rail transition slick and sly; Number be the disclosed a kind of electrically driven curtain guide rail of Chinese patent of CN201070238Y perhaps like Granted publication, the curved bending of guide rail.

Yet the guide rail that above-mentioned these curtain are used be not easy to transportation after the bending, and the cost of bending is also higher.

The utility model content

The utility model technical problem to be solved provides a kind of Rail for curtain, is convenient to transportation, and has reduced production technology and practiced thrift cost.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Rail for curtain, comprise straight rail, and it is characterized in that, also comprise the transition piece that is used to connect two sections said straight rails with certain radian.

Pegging graft with said straight rail and cooperate in the two ends of said transition piece, just can transition piece be combined to form curved rail with straight rail through shirtsleeve operation.

Said straight rail upper end is I-shaped, and the two ends of said transition piece form the corresponding slot of shape.Make the cooperation of can pegging graft of transition piece and straight rail thus.

The both sides of pars infrasegmentalis are provided with track inside portion and track outside portion and can in guide rail, slide to form chute, to make the coaster that drives curtain slip usefulness in the said transition piece.

Be fixed with compressing tablet and the outer compressing tablet of track in the track under said track inside portion and the said track outside portion respectively; Because the curtain that in guide rail, slides may shake in moving or power is not enough, thus through setting intensity or the dynamics that two compressing tablets fix increases guide rail.

Compared with prior art; The advantage of the utility model is: through with transition piece two sections straight rails being connected to form curved rail; Need not straight rail bending, is straight rail all when making transportation, greatly facilitates transportation; And save bending technique, made guide rail can not receive the restriction of bending technique and also made things convenient for to produce and practiced thrift cost; Because the curtain that in guide rail, slides may shake in moving or power is not enough, thus through setting intensity or the dynamics that two compressing tablets fix increases guide rail.

Description of drawings

Fig. 1 is the perspective view of the guide rail of the utility model;

Fig. 2 is the structural representation (reverse with Fig. 1) of the guide rail of the utility model;

Fig. 3 is the decomposition texture sketch map of another embodiment of the guide rail of the utility model.

The specific embodiment

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

Referring to Fig. 1, a kind of Rail for curtain comprises the transition piece 1 with certain radian, and its radian conforms to required lead curve, can be processed by metal material or nonmetallic materials.

In the present embodiment, peg graft with straight rail 2 and cooperate to form curved rail in the two ends of transition piece 1.It is I-shaped 21 that the upper end of straight rail 2 is, and the two ends of transition piece 1 form the corresponding slot 11 of shape, make straight rail 2 to insert thus and form bend pipe in the transition piece 1.Transition piece 1 also can adopt other connected mode to fix with straight rail 2, as passes through bolt.

Referring to Fig. 2; The stage casing of transition piece 1 is identical with existing curtain rail commonly used; Both sides through pars infrasegmentalis in transition piece 1 are provided with track inside portion 12 and form chutes 14 with track outside portion 13, slide within it for the coaster that drives curtain etc., to carry out the operation that opens or closes of curtain.

Material is piled up and is caused dimensional discrepancy, the upper surface of transition piece 1 to have the groove 15 of same radian thus when avoiding making.

Referring to Fig. 3, be that with the difference of Fig. 1, embodiment shown in Figure 2 track inside portion 12 is fixed with compressing tablet 16 and the outer compressing tablet 17 of track in the track for 13 times respectively with the track outside portion, and is preferred, can realize fixing through bolt.Because the curtain that in guide rail, slides may shake in moving or power is not enough, thus through setting intensity or the dynamics that two compressing tablets fix increases guide rail.

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.
