Description

Technical Field

[0001] This application relates to the technical field of electric curtain tracks, and specifically to a curtain track. Background Art

[0002] A curtain track is a curtain accessory used to hang curtains so that the curtains can open and close, and can also enhance the beauty of the curtain fabric. There are many varieties, which are divided into two major series: visible tracks and hidden tracks. The visible tracks include wooden rods, aluminum alloy rods, steel pipes, iron art rods, plastic steel rods, etc. The common form is an artistic rod.

[0003] The existing electric track body is completely made of aluminum alloy. When the metal track contacts the guide wheel, due to reasons such as the surface polishing accuracy and long-term use wear, the friction force with the wheel hub is relatively large, resulting in a poor sound insulation effect.

[0004] Therefore, this application provides a curtain track to solve the above problems. Utility Model Content

[0005] This application provides a curtain track, aiming to solve the problems in the background art that the existing electric track body is completely made of aluminum alloy. When the metal track contacts the guide wheel, due to reasons such as the surface polishing accuracy and long-term use wear, the friction force with the wheel hub is relatively large, resulting in a poor sound insulation effect, etc.

[0006] To achieve the above object, this application provides the following technical solution: a curtain track, including an aluminum alloy outer track and a track noise reduction mechanism fixedly installed in the aluminum alloy outer track:

[0007] The track noise reduction mechanism includes an inner track fixedly installed in the cavity of the aluminum alloy outer track. A chute opening adapted to the aluminum alloy outer track is provided on the inner track. Two partition plates are oppositely arranged on both sides of the chute opening in the inner track. The two partition plates divide the position between the inner side wall of the inner track and the partition plates into sound absorption grooves, and sound absorption cotton strips are installed in the sound absorption grooves. In this way, when installing the curtain track, the inner track is snapped into the aluminum alloy outer track, and then the sound absorption cotton strips are snapped into the two sound absorption grooves. The partition plates limit the sound absorption cotton strips. The pulley is installed in the chute opening. The pulley contacts the inner track to reduce friction. The noise generated during use will also be absorbed by the sound absorption cotton strips in the two sound absorption grooves on both sides, thus achieving a good noise reduction effect. Compared with the common single aluminum alloy track, the use experience is better.

[0008] Preferably, in order to install the sound absorption cotton strip, a support and guide sleeve strip adapted to the inner wall of the sound absorption groove is sleeved on the outer side wall of the sound absorption cotton strip. There will be no problem that it is inconvenient to adjust due to bending when passing through the sound absorption groove.

[0009] Preferably, in order to fix the support guide strip, hanging grooves are formed on the opposite surfaces of the two partition plates. The surface of the support guide strip facing the hanging groove is of an open design, and elastic cards adapted to the hanging grooves are disposed opposite to each other at the end positions on the outer side wall of the support guide strip facing the hanging groove. The two elastic cards will expand towards both sides and thus be clamped with the edges of the hanging grooves, facilitating the assembly of the support guide strip.

[0010] Preferably, in order to fix the sound-absorbing cotton strip, a number of evenly arranged anti-detachment convex blocks are fixedly installed on the inner side wall of the support guide strip. It can effectively prevent the sound-absorbing cotton strip from slipping out of the support guide strip, being more stable and reliable.

[0011] Preferably, in order to extend the length of the track, the curtain track further includes a splicing mechanism. The splicing mechanism includes a pull plate movably installed on the outer tracks of adjacent two aluminum alloys. A pull groove is formed on the pull plate, and a lead screw is rotatably installed in the pull groove. One end of the lead screw penetrates through the side wall of the pull groove and a knob is fixedly installed at the end. Two L-shaped blocks are disposed opposite to each other in the pull groove. One of the blocks is fixedly installed at one end in the pull groove, and the other block is screwed on the lead screw. A card slot adapted to the block is formed on the outer side wall of the aluminum alloy outer track. It is convenient to adjust the length of the device according to requirements, with better adaptability and convenient for maintenance and transportation.

[0012] Preferably, in order to rotate the lead screw, an internal hexagonal notch is formed at the end of the knob far from the lead screw. The installation methods are diverse and the selectivity is high.

[0013] For this curtain track, the inner track is snapped into the aluminum alloy outer track, and then the sound-absorbing cotton strip is snapped into the two sound-absorbing grooves. The partition plates limit the sound-absorbing cotton strip. The pulley is installed in the chute opening. The pulley contacts the inner track to reduce friction, and the noise generated during use will also be absorbed by the sound-absorbing cotton strips in the two sound-absorbing grooves on both sides, thus achieving a good noise reduction effect. Compared with the common single aluminum alloy track, the use experience is better.

[0014] For this curtain track, the two aluminum alloy outer tracks are butted end to end. Then, the side of the pull plate with the block is turned upwards, and the knob is rotated to drive the lead screw to rotate, thereby adjusting the position of a block screwed on the lead screw in the pull groove, so that the two blocks are aligned and inserted into the two card slots at the ends of the two aluminum alloy outer tracks. Then, the knob is rotated again to drive the lead screw to rotate, thereby tightening the distance between the two blocks, so that the two blocks are clamped with the card slots, completing the docking and fixing of the multi-section aluminum alloy outer tracks, being convenient to adjust the length of the device according to requirements, with better adaptability and convenient for maintenance and transportation.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Embodiment 1

[0023] This embodiment provides a curtain track, as Figures 1-4 shown. The curtain track includes an aluminum alloy outer track 1 and a track noise reduction mechanism 2 fixedly installed inside the aluminum alloy outer track 1:

[0024] The track noise reduction mechanism 2 includes an inner track 21 fixedly installed inside the cavity of the aluminum alloy outer track 1. A slide groove opening 22 adapted to the aluminum alloy outer track 1 is provided on the inner track 21. Two partition boards 23 are oppositely arranged on both sides of the slide groove opening 22 inside the inner track 21. The position between the inner side wall of the inner track 21 and the partition boards 23 is divided into a sound absorption groove 24, and a sound absorption cotton strip 25 is installed in the sound absorption groove 24.

[0025] During use, the inner track 21 is snapped into the aluminum alloy outer track 1, and then the sound absorption cotton strip 25 is snapped into the two sound absorption grooves 24. The partition boards 23 limit the sound absorption cotton strip 25. The pulley is installed in the slide groove opening 22, and the contact between the pulley and the inner track 21 reduces friction. The noise generated during use will also be absorbed by the sound absorption cotton strips 25 in the two sound absorption grooves 24 on both sides, thereby achieving a good noise reduction effect. Compared with the common single - body aluminum alloy track, the use experience is better.

[0026] It should be noted that in order to reduce the friction between the aluminum alloy outer track 1 made of metal and the pulley, the inner track 21 is no longer made of metal, but a more wear-resistant composite material such as silicon carbide composite ceramic sheets, etc.

[0027] Specifically, a support and guiding strip 26 adapted to the inner wall of the sound absorption groove 24 is sleeved on the outer side wall of the sound absorption cotton strip 25. During use, the sound absorption cotton strip 25 is inserted into the support and guiding strip 26, and then the support and guiding strip 26 is inserted into the sound absorption groove 24, making the installation of the sound absorption cotton strip 25 more convenient and avoiding the problem of inconvenient adjustment due to bending when passing through the sound absorption groove 24.

[0028] More specifically, hanging grooves 27 are formed on the opposite surfaces of the two partition plates 23. The side of the support and guiding strip 26 facing the hanging grooves 27 is of an open design. Elastic cards 28 adapted to the hanging grooves 27 are disposed opposite to each other at the end positions on the outer side wall of the support and guiding strip 26 facing the hanging grooves 27. During use, when the support and guiding strip 26 is inserted into the sound absorption groove 24, the two elastic cards 28 are pinched and squeezed inward during insertion, so that the distance between the two elastic cards 28 is reduced and they are clamped with the hanging grooves 27. After the support and guiding strip 26 is completely inserted, the elastic cards 28 are no longer manually squeezed, and the two elastic cards 28 will expand toward both sides and thus be clamped tightly with the edges of the hanging grooves 27, facilitating the assembly of the support and guiding strip 26.

[0029] Furthermore, a number of evenly arranged anti - detachment convex blocks 29 are fixedly installed on the inner side wall of the support and guiding strip 26. During use, the sound absorption cotton strip 25 is inserted into the support and guiding strip 26 from one end until it completely enters the support and guiding strip 26. The anti - detachment convex blocks 29 squeeze the sound absorption cotton strip 25 from the side, playing a role in fixing the sound absorption cotton strip 25. Without external force applied, it can effectively prevent the sound absorption cotton strip 25 from slipping out of the support and guiding strip 26, being more stable and reliable.

[0030] Embodiment 2

[0031] Different from Embodiment 1, when installing a curtain rail for a large - width window opening, the ultra - long rail is not convenient for transportation. For this reason, the curtain track further includes a splicing mechanism 3. The splicing mechanism 3 includes a pull plate 31 movably installed on two adjacent aluminum alloy outer tracks 1. A pull groove 32 is formed on the pull plate 31. A lead screw 33 is rotatably installed in the pull groove 32. One end of the lead screw 33 penetrates through the side wall of the pull groove 32 and a knob 34 is fixedly installed at the end. Two L - shaped clamping blocks 35 are disposed opposite to each other in the pull groove 32. One of the clamping blocks 35 is fixedly installed at one end in the pull groove 32, and the other clamping block 35 is screwed on the lead screw 33. A clamping groove 36 adapted to the clamping block 35 is formed on the outer side wall of the aluminum alloy outer track 1.

[0032] During use, the aluminum alloy outer track 1, the inner track 21 inside it, and the sound-absorbing cotton strip 25 are all set as short pieces of equal length for convenient transportation. During installation, the two aluminum alloy outer tracks 1 are butt-jointed end to end. Then, the side of the pull plate 31 with the fixture block 35 is turned upwards, and the knob 34 is rotated to drive the screw rod 33 to rotate, thereby adjusting the position of a fixture block 35 screwed to the screw rod 33 within the pull groove 32, so that the two fixture blocks 35 are inserted into the two card slots 36 at the ends of the two aluminum alloy outer tracks 1 in alignment. Then, the knob 34 is rotated again to drive the screw rod 33 to rotate, thereby tightening the distance between the two fixture blocks 35, so that the two fixture blocks 35 are clamped with the card slots 36, completing the butt-joint fixation of the multi-section aluminum alloy outer tracks 1, facilitating the adjustment of the length of the device according to requirements, with better adaptability and being convenient for maintenance and transportation.

[0033] Further, an internal hexagonal notch 37 is provided at one end of the knob 34 away from the screw rod 33. During use, the knob 34 can be rotated manually, or a special hexagonal wrench can be inserted into the internal hexagonal notch 37 to further tighten the screw rod 33. There are various installation methods with high selectivity.

[0034] As described above, only the preferred specific implementation manner of this application is provided, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application, according to the technical solution and its concept of this application, makes equivalent substitutions or changes, and should be covered within the protection scope of this application.
