Abstract
A louver type sound absorption bamboo curtain capable of vertically rotating and being rolled and unrolled comprises a curtain body, pulleys, slide rails and dragging ropes, wherein the pulleys, the slide rail and the dragging ropes are used for controlling rotating direction and rolling and unrolling of the curtain body, the curtain body basically comprises bamboo sections (5) with inner cavities, two close ends of the bamboo sections are bamboo joints (4), sound absorption holes (6) are arranged between each two adjacent bamboo joints, the outer sides of the two bamboo joints are respectively provided with a braided string through hole (1), braided strings (2) are threaded into the through holes on the same side to transversely parallelly connect the bamboo sections (5) one by one, the upper portion of each vertical connected bamboo section is provided with connecting sheets (3) connected with the pulleys, multiple vertical connected bamboo sections are mounted from the top and hung to form a plane on the same slide rail, the sound absorption holes (6) uniformly face outwards. The louver type sound absorption bamboo curtain is made of original bamboo sections which are not required to be cut into strips, are free of processes of bamboo green and inner layer removal and can be used sufficiently, is simple in process, can be used for doors and windows, can absorb noise of low and medium frequency by 1-2db (decibel), and is environment-friendly and low-carbon.
Description
Technical field
The utility model relates to a kind of door curtain or curtain of louvered, is that a kind of former bamboo bamboo section with the band inner chamber is the vertical top dress of raw material and the door curtain and the curtain of energy sound-absorbing.
Background technology
The existing bamboo curtain splint of making as raw material with bamboo wood mostly is to split and is cut into the bamboo curtain splint that braiding forms behind the bamboo chip, and the inner chamber that does not have former bamboo bamboo section to have, bamboo curtain splint itself are not had a sound absorption function, and shading and windproof effect are only arranged.By retrieval, still find no and close the inner chamber that utilizes former bamboo bamboo section, according to the sound-absorbing principle of single hole resonance acoustical absorption body, relevant report and the product of making the louvered sound-absorbing bamboo curtain splint of vertical top dress appear on the market.
The utility model content
The technical problems to be solved in the utility model provides the louvered sound-absorbing bamboo curtain splint of a kind of vertical rotation and folding and unfolding.
The technical scheme that solves the problems of the technologies described above employing is: this is vertical to rotate and the louvered sound-absorbing bamboo curtain splint of folding and unfolding, comprises the curtain body and control the curtain body turning to pulley, slide rail and pulling rope with folding and unfolding, and pulley places slide rail, and an end of pulling rope is fixed on the pulley.The basic composition unit of curtain body is the bamboo section of band inner chamber, this bamboo section is a ring near two ends, logical inner chamber is arranged between two rings but not break-through to the sound-absorption hole of wall, respectively there is the braided wire string hole of a break-through to wall in the outside of two rings, braided wire by homonymy string hole with each bamboo section one by one laterally abreast Series Code become a perpendicular string, the brace that links to each other with pulley is arranged at each top of erecting string bamboo section, and the perpendicular string of polylith bamboo section is pushed up to adorn to erect on same slide rail and hung into a plane, and the sound-absorption hole unanimity toward the outer side.
Said bamboo section is for only with the bamboo section of an inner chamber.
The diameter 2-3mm of said bamboo segment length 100-150mm, external diameter 14-18mm, internal diameter 10-14mm, sound-absorption hole, each bamboo Duan Youyi sound-absorption hole.
The beneficial effects of the utility model are that the sound-absorbing bamboo curtain splint is a raw material with former bamboo bamboo section, needn't split the thin bamboo strip, do not remove surf green and tabasheer, and prepared using is abundant, process easy, green, low-carbon (LC) and environmental protection.The development of current social urbanization, it is concentrated relatively that personnel are lived, and residential block star Luo Qibu, traffic noise, domestic noise are serious day by day, and the bamboo curtain splint of sound absorption function more meets people's demand.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
The utility model is described in detail below in conjunction with embodiment and with reference to accompanying drawing: the raw material of the louvered sound-absorbing bamboo curtain splint (hereinafter to be referred as the sound-absorbing bamboo curtain splint) of this vertical rotation and folding and unfolding selects for use 1-3 to give birth to bamboo, be cut into the bamboo section, each bamboo section 5 keeps two rings and an inner chamber at least, bamboo segment length 100-150mm, external diameter 14-18mm, internal diameter 10-14mm, fixed these parameters mainly are to consider that people are to curtain, the visual custom of door curtain thickness, anticracking is handled and finish is handled if need carry out, the bamboo section can be immersed in weight ratio and be in 36% the calcium chloride water and soak 1-2 days, dry that the back is outer varnishes.Each makes a call to the braided wire string hole 1 of a break-through to wall in the outside of two rings 4 again, make a call to a sound-absorption hole 6 between two rings 4, the aperture in braided wire string hole 1 is should little principle do under the prerequisite of conveniently passing braided wire 2, the aperture of sound-absorption hole 6 is 2-3mm, braided wire 2 should be used durable line, on the braided wire string hole 1 at each bamboo section two ends, pass one by one, with each bamboo section laterally abreast one by one Series Code become a perpendicular string, the brace 3 on the top of each perpendicular string bamboo section links to each other with slide rail with the pulley of its top, pulley places slide rail, pulling rope one end is fixed on the pulley, if a certain perpendicular string bamboo section need turn to or during folding and unfolding, the free-end that only with hand spurs corresponding pulling rope can move, and this is the known technology of extensive usefulness in existing plastic sheet louvered door curtain and the curtain, does not carefully state.
It should be noted that what of thickness length, sound-absorbing pore size and bamboo section inner chamber of bamboo section, also should press door and window size, user's vision adaptive and the existing situation of raw material, grasp flexibly, can not limited by above-mentioned parameter.
Bamboo curtain splint and the identical bamboo curtain splint ratio that does not have sound-absorption hole with sound-absorption hole 6 can sound-absorbing 1-2db to the noise of medium and low frequency.
