Description

Scalable track and the hanging wheel of curtain

Technical field

The utility model relates to curtain, particularly a kind of scalable track and hanging wheel of curtain.

Background technology

Curtain rail in the market, generally not flexibles, because curtain rail is longer, give storage, transportation and install all can make troubles, during storage, take up an area more, carrying effort during transportation, and when mounted, if floor is higher, longer curtain rail, cannot put in elevator, walk stair very inconvenient again, and, also need to cut according to the width of window, time-consuming, these all have much room for improvement.

Utility model content

Technical problem to be solved in the utility model, is to provide a kind of scalable track and hanging wheel of curtain, uses very flexibly, can not only save storage space, and transportation and install all more convenient.

For solving the problems of the technologies described above, the technical solution of the utility model is: scalable track and hanging wheel that a kind of curtain is provided, hanging wheel comprises two pulleys that wheel seat and both sides thereof are connected, scalable track comprises outside track and inner orbit, the longitudinal section of the two is the downward groove shape of notch, and inner orbit activity is plugged in outside track;

The groove mouth of described outside track, relatively be provided with the quarter bend bar of two band right-angle bendings, the groove mouth of inner orbit, relatively be provided with the double-bending bar of two band twice bendings, article two, double-bending bar is corresponding identical with two quarter bend bars respectively, four height equates, the upper horizontal edge of A of two double-bending bars is also neat with the upper horizontal edge of B of two quarter bend bars respectively;

Described wheel seat is placed in the groove mouth of inner orbit and outside track simultaneously, and two pulleys are all movably placed on the upper horizontal edge of A and the upper horizontal edge of B, and the outside of two pulleys, is all connected with position-limited wheel sheet.

Scalable track and the hanging wheel of above-mentioned curtain, owing to being provided with interior outside track, curtain rail is free-extension as required, and length shortens greatly, uses very flexibly, can not only save storage space, and transportation and install all more convenient.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Fig. 1 is the longitudinal section of described utility model;

Fig. 2 is the use state diagram of described inner orbit while stretching out outside track.

The specific embodiment

Referring to Fig. 1, Fig. 2, a kind of scalable track and hanging wheel of curtain are provided, and hanging wheel comprises two pulleys 2 that wheel seat 1 and both sides thereof are connected, and scalable track comprises outside track 3 and inner orbit 4, the longitudinal section of the two is the downward groove shape of notch, and inner orbit 4 activities are plugged in outside track 3; The groove mouth of described outside track 3, relatively be provided with the quarter bend bar 5 of two band right-angle bendings, the groove mouth of inner orbit 4, relatively be provided with the double-bending bar 6 of two band twice bendings, article two, double-bending bar 6 is corresponding identical with two quarter bend bars 5 respectively, four height equates, the upper horizontal edge 7 of A of two double-bending bars 6 is also neat with the upper horizontal edge 8 of B of two quarter bend bars 5 respectively; Described wheel seat 1 is placed in the groove mouth of inner orbit 4 and outside track 3 simultaneously, and two pulleys 2 are all movably placed on the upper horizontal edge 7 of A and the upper horizontal edge 8 of B, and the outside of two pulleys 2, is all connected with position-limited wheel sheet 9.

During use, can be according to the width of window, by inner orbit 4 from the groove frame in-draw of outside track 3 out, make the stretched portion length sum of outside track 3 and inner orbit 4, reach needed curtain rail length.Due to 4 tensile elongations of inner orbit, free adjustment, uses very flexible as required.After inner orbit 4 part from outside track 3 is stretched, inner orbit 4 is arranged in the part of outside track 3, the upper horizontal edge 7 of A is still also neat with the upper horizontal edge 8 of B, during two pulleys 2 slide, slides on A on horizontal edge 7 and B on horizontal edge 8 simultaneously, now, article two, a relative side on quarter bend bar 5, plays position-limiting action to wheel seat 1 jointly, and two pulleys 2 are also corresponding to be subject to spacing with wheel seat 1, thereby can not there is slanting to the left or to the right in the sliding of two pulleys 2, and inner orbit 4 stretches out the part outside outside track 3, although two pulleys 2 only slide on horizontal edge 7 on A, but because the upper horizontal edge 7 of A is identical with the height of the upper horizontal edge 8 of B, and, the left side of the one double-bending bar 6 in the left side, to one, left side pulley, 2 connected position-limited wheel sheets 9, play position-limiting action, the right side of the one double-bending bar 6 in the right, to one, the right pulley, 2 connected position-limited wheel sheets 9, play position-limiting action, also be the position-limited wheel sheet 9 on the left side, can not slant to the right, the position-limited wheel sheet 9 on the right, can not slant left, thereby make wheel seat 1 and two pulleys 2 also all be subject to spacing, can not there is slanting to the left or to the right in the sliding of two pulleys 2, thereby slide smooth and easy at all unaffected, in addition, inner orbit 4 parts are stretched out after outside track 3, do not peg graft on outside track 3 part of inner orbit 4, although two pulleys 2 only slide on horizontal edge 8 on B, but same as above, due to a side relative on two quarter bend bars 5, jointly wheel seat 1 is played to position-limiting action, two pulleys 2 are also corresponding to be subject to spacing with wheel seat 1, thereby the sliding of two pulleys 2, now can there is not slanting to the left or to the right yet, so, when two pulleys 2 slide on horizontal edge 8 separately on the B of outside track 3, equally also can guarantee to slide smooth and easy.The effect of above-mentioned position-limited wheel sheet 9 is, can limit pulley 2 slanting or upper jumping in sliding, and that avoids that impact slides is smooth and easy.

Above-described embodiment is preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of doing change, and all should belong to protection category of the present utility model.
