Abstract

The utility model discloses a curtain rack. The curtain rack comprises a cross beam and a lifting ring; the position in the lifting ring, relative to a hook ring on the lifting ring, is detachably connected with a roller shelf; extending shafts on two sides of the roller shelf are provided with a roller respectively; and the upper part of the cross beam is provided with a longitudinal protrusion, the upper part of the lifting ring is provided with an upper notch, a shaft is in the upper notch, a rotary sleeve capable of rotating around the shaft is idly sleeved on the shaft, and the outside diameter of the rotary sleeve is smaller than the diameter of the cross section of a circular ring of the lifting ring. Because the rollers of a rolling bearing sleeved on the roller shelf roll in a track limited by a flange on the cross beam in the lifting ring, the curtain rack achieves the effects that the rollers for the lifting ring roll in the cross beam and do not separate from the track.

Description

A kind of curtain rod arm

Technical field

The utility model relates to a kind of improvement of curtain rod arm, and particularly a kind of slip is curtain rod arm easily, belongs to the daily living article technical field.

Background technology

Existing curtain rod arm is of a great variety, comprise manual, electronic, machinery and remote control, wherein, modal is a kind of hand-operated curtain frame that is rolled in orbit by roller, because the structure of roller is comparatively complicated comparatively speaking, it is whether smooth and easy that the accuracy of its processing directly has influence on the slip of roller, also can produce the draw-in groove phenomenon sometimes.

The suspension ring that hang curtain commonly used slide on cylindric guide rail in the family now, so that open or close curtain, the friction of this mode roller is bigger, and the suspension ring guide rail surface of hindering easy to hang, and this has more increased friction, has also influenced the attractive in appearance of curtain rod arm.In addition, the noise that roller produces during owing to the pulling curtain is also bigger, has influenced the comfort level that people use.

The utility model content

At above-mentioned deficiency of the prior art, it is a kind of simple in structure, easy to operate and flexibly light and handy that the utility model provides, and is not easy draw-in groove, the curtain rod arm that noise is less.

The purpose of this utility model is achieved in that a kind of curtain rod arm, comprises crossbeam and suspension ring, it is characterized in that, with respect to the detachable turning rolls that is connected with in the position of the shackle on the suspension ring in suspension ring, a wheel is arranged respectively on the projecting shaft of turning rolls both sides; Vertical projection is arranged at the top of crossbeam, and last breach is arranged at the top of suspension ring, and described going up in the breach has axle, is set with the rotary sleeve that can pivot on axle, and the external diameter of rotary sleeve is less than the diameter of the annulus cross section of suspension ring.

Further, in the bottom of the crossbeam of hollow following breach is arranged, described gap edge down is along the flange of the elongated oriented convex of crossbeam; Turning rolls passes down breach, and two wheels on the turning rolls are seated on the track that flange limited of convex; The suspension ring sky is enclosed within outside the crossbeam.

In the described crossbeam reinforcement is arranged, the crossbeam two ends respectively are provided with a detachable end socket.

After adopting such structure, because suspension ring are to provide a kind of suspension ring to roll in crossbeam with roller in order to the wheel that rolling bearing is sleeved on the turning rolls along rolling in the track of the flange limit on the crossbeam, having reached, the curtain rod arm that can not derail again.

Among the figure, 1-crossbeam, 2-suspension ring, 3-turning rolls, 4-wheel, 5-projection, the last breach of 6-, 7-rotary sleeve, breach under the 8-, 9-flange, 10-reinforcement, 11-end socket.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment 1: as depicted in figs. 1 and 2, a kind of curtain rod arm, comprise crossbeam 1 and suspension ring 2, detachably be fixedly connected with turning rolls 3, respectively have one to be installed on the wheel 4 on the axle on the turning rolls 3 both sides projecting shafts with rolling bearing with respect to the position of the shackle on the suspension ring 2 in suspension ring; Following breach 8 is arranged at the bottom of the crossbeam 1 of hollow, and following breach 8 edges are along the flange 9 of the elongated oriented convex of crossbeam; Turning rolls 3 passes down breach 8, on the track that the flange 9 that 3 two wheels are seated in convex on the turning rolls is limited.

Embodiment 2: as depicted in figs. 1 and 2, a kind of curtain rod arm, comprise crossbeam 1 and suspension ring 2, the crossbeam 1 outer suspension ring 2 that hanging curtain that are set with, the top of crossbeam has vertical protruding 5, and last breach 6 is arranged at the top of suspension ring 2, in the last breach 6 axle is arranged, be set with the rotary sleeve 7 that can pivot on the axle, the external diameter of rotary sleeve 7 is less than the diameter of the annulus cross section of suspension ring.

Embodiment 3: as depicted in figs. 1 and 2, on the basis of embodiment 1 or 2, reinforcement 10 is arranged in the crossbeam 1, crossbeam 1 two ends respectively are provided with a detachable end socket 11.
