Description

Technical Field

[0001] The present application relates to the technical field of curtain track structures, and in particular to a track structure using double-layer curtains. Background Art

[0002] Electric curtains can bring certain conveniences to people when used in smart houses. Usually, electric curtains are double-layer curtains, one layer is a blackout curtain with better light blocking properties, and the other layer is a gauze curtain with better light transmittance. Electric curtains control the movement of the blackout curtain and the gauze curtain through a transmission rod.

[0003] In the related art, the track structure for the transmission rod is a double-track structure. The two tracks are arranged in parallel on one side of the courtyard window, so that the blackout curtain and the gauze curtain overlap each other in a direction parallel to the window. When the blackout curtain is moved and opened, softer light can pass through the gauze curtain into the room.

[0004] With regard to the above-mentioned related technologies, when the two tracks are arranged in parallel in the horizontal direction on the side away from the window, the space occupied in the horizontal direction increases. When decorating the ceiling of some rooms, the space reserved near the edge of the window is small, which brings inconvenience to the installation of the track of the electric curtain. Utility Model Content

[0005] In order to reduce the space occupied by the double-layer curtain track on the horizontal side and facilitate installation in a small horizontal space, the present application provides a track structure using a double-layer curtain.

[0006] The track structure using double-layer curtains provided in this application adopts the following technical solution:

[0007] A track structure using a double-layer curtain, comprising:

[0008] The first track is provided with a first sliding groove for the transmission rod to be inserted into;

[0009] The second track is fixed on the side of the first track away from the ground. The second track and the first track are arranged parallel to each other, and the second track intersects with the projection of the first track in the vertical direction. A second slide groove is provided on the side of the second track away from the window for the transmission rod to be embedded.

[0010] By adopting the above technical solution, the first track and the second track are respectively provided with a first slide groove and a second slide groove for the corresponding transmission rod to be embedded, so that after the blackout curtain and the gauze curtain are connected to the corresponding transmission rod, movement control can be achieved, and the first track and the second track are overlapped and parallel to each other in the vertical direction, which can reduce the space occupied in the horizontal direction, and help to reserve more space for the wall ceiling of the building when the track structure is installed in a narrow horizontal space.

[0011] Optionally, the second slide groove is inclined toward the first track away from the window, and the inclination angle between the second track and the first track is 30° to 45°.

[0012] By adopting the above technical solution, when the second slide groove is inclined toward the first track side, it is inclined toward the ground side, so that when the curtain falls from the second slide groove, it is not easy to directly contact the curtain hanging in the first slide groove, which helps to reduce the mutual friction between the curtains and reduce the probability of damage due to friction.

[0013] Optionally, both parallel inner walls of the slot of the second slide groove are fixedly provided with limiting convex pieces, and the two limiting convex pieces are bent toward each other, and when the curtain falls from the slot of the second slide groove, the two limiting convex pieces are spaced apart from the curtain.

[0014] By adopting the above technical solution, when the curtain is shaken by wind, the setting of the limiting protrusions can provide abutment and limit for both sides of the curtain, so as to prevent the curtain as a whole from shaking excessively. In the naturally falling state, the curtain and the two limiting protrusions are kept at a distance, thereby reducing the wear and contact of the curtain during movement in the natural state, which helps to extend the service life of the curtain.

[0015] Optionally, a first hanging portion is fixedly provided on the side wall of the first track away from the window, and the first hanging portion and the groove edge of the second slide groove are spaced apart along the side wall to form a first light strip groove, and the first light strip groove is for an external light strip to be embedded, and when the curtain falls from the groove of the second slide groove, the groove of the first light strip groove and the curtain are arranged facing each other.

[0016] By adopting the above technical solution, the first hanging part forms a first light strip groove on the edge side wall of the second slide groove opening, so that the external light strip can be embedded in the first light strip groove to illuminate the ambient light on the curtain, thereby increasing the lighting effect of the curtain.

[0017] Optionally, a second light strip groove is formed on a side wall of the second track at one side away from the ground.

[0018] By adopting the above technical solution, a second light strip groove is added on the basis of the first light strip groove, so that the number of light strips installed on the first track and the second track can be increased to provide light strip installations with different effects, thereby increasing the lighting effect of the light strip and meeting the lighting effect usage needs of different groups of people.

[0019] Optionally, a reinforcing connecting plate is further included, on which a first connecting portion and a second connecting portion are fixedly provided, wherein the first connecting portion is fixedly connected to the first track, and the second connecting portion is fixedly connected to the second track.

[0020] By adopting the above technical solution, the strengthening connecting plate connects the first track and the second track through the first connecting part and the second connecting part, which can increase the strength of the connection structure between the first track and the second track, making it difficult for the first track and the second track to deform when bearing the weight of the curtain.

[0021] Optionally, the second connecting portion includes a first fixing plate and a second fixing plate, the same side wall of the first fixing plate and the second fixing plate are fixedly connected to the first connecting portion, the other side wall of the first fixing plate and the second fixing plate are fixedly connected to the second track, and the first fixing plate and the second fixing plate are spaced apart.

[0022] By adopting the above technical solution, the arrangement of the first fixing plate and the second fixing plate increases the connection area between the second rail and the second connecting part, and the first fixing plate and the second fixing plate are arranged at an interval, so that the second connecting part can connect and fix different positions of the second rail, which helps to increase the connection firmness between the second rail and the second connecting part.

[0023] Optionally, both the first rail and the second rail are made of hard metal material.

[0024] By adopting the above technical solution, when the first rail and the second rail are made of hard metal material, the first rail and the second rail both have good structural strength and hardness, so that the first rail and the second rail are not easy to deform and can carry heavy curtains.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The first track and the second track are arranged to overlap in the vertical direction, and the first track and the second track are arranged in parallel in the vertical direction, which can reduce the space occupied in the horizontal direction, help to install in a narrow horizontal space, and reserve more space for the wall and ceiling of the building;

[0027] 2. When the curtain is shaken by wind, the setting of the limit convex piece can provide abutment and limit for both sides of the curtain, so that the curtain as a whole will not shake excessively. In the natural hanging state, the curtain and the two limit convex pieces are kept at a distance, so as to reduce the wear and contact of the curtain in the natural state during the movement, which helps to extend the service life of the curtain;

[0028] 3. The first hanging portion forms a first light strip groove on the edge side wall of the second slide groove opening, so that the external light strip can be embedded in the first light strip groove to illuminate the ambient light on the curtain, thereby increasing the lighting effect of the curtain.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 In this embodiment, the direction indicated by the z-axis in the figure is up, the direction opposite to the z-axis is down, the direction indicated by the x-axis is left, the direction opposite to the x-axis is right, the direction indicated by the y-axis is front, and the direction opposite to the y-axis is back.

[0035] The present application embodiment discloses a track structure using a double-layer curtain. Figure 1 and Figure 2 The track structure of the double-layer curtain includes a first track 1 and a second track 2. The second track 2 is fixedly connected to the upper side wall of the first track 1. The first track 1 and the second track 2 are arranged parallel to each other. A first slide groove 11 is provided at the lower side wall of the first track 1 for a transmission rod to be embedded in, and a second slide groove 21 is provided at the left side wall of the second track 2 for another transmission rod to be embedded in. Therefore, when the first track and the second track 2 are installed with the curtain 4, the space occupied in the left and right horizontal directions can be reduced, which is convenient for installation when the installation space in the left and right horizontal directions is narrow.

[0036] Reference Figure 1 and Figure 2The cross-sectional structures of the first track 1 and the second track 2 in the front-to-back direction are the same, and the first track 1 and the second track 2 are both extended in the front-to-back direction. When installing the curtain 4, the corresponding transmission rod and the transmission mechanism for driving the transmission rod to rotate are pre-installed in the first slide 11 or the second slide 21, and then the curtain 4 and the transmission rod are relatively fixed so that the curtain 4 hangs from top to bottom. When the curtain 4 needs to be controlled to move, it can be achieved by controlling the rotation direction and rotation duration of the transmission rod. The installation and use of the transmission rod, the curtain 4 and the transmission mechanism are all existing technologies in the field, and are not the focus of the invention of this application, so they are not described in detail. In this embodiment, the specific installation positions of the gauze curtain and the blackout curtain are set by the staff according to actual needs, and the curtain is used as the representation below.

[0037] In order to make the first rail 1 and the second rail 2 have better physical properties, the first rail 1 and the second rail 2 are both made of hard metal materials. In this embodiment, aluminum alloy materials are used as an example.

[0038] Reference Figure 1 and Figure 2 , the distance between the inner wall of the slot of the first chute 11 on the lower side in the left-right direction is 3 cm, and the distance between the slot of the second chute 21 and the opposite side wall is also 3 cm. It should be further explained that the inclination angle between the second track 2 and the first track 1 ranges from 30° to 45°, so that the projection overlap ratio of the first track 1 and the second track 2 in the vertical direction is one-half, thereby reducing the space occupancy in the left-right horizontal direction.

[0039] Specifically, when the value is 45°, Figure 3 As shown, when the curtain 4 falls from the second slide groove 21 to the ground, the curtain 4 is close to the right inner wall of the notch of the second slide groove 21. Figure 4 As shown, when the angle is 30°, the curtain 4 is closer to the left inner wall of the notch of the second slide groove 21 .

[0040] In this embodiment, the inclination angle value between the second track 2 and the first track 1 is selected as 43.5° for introduction, so that the slot of the second slide groove 21 is inclined from top to bottom toward the left side. When the curtain 4 falls to the ground from the second slide groove 21, it is located in the center position of the left and right inner walls of the slot of the second slide groove 21, which can effectively reduce the probability of contact friction between the curtain 4 and the inner wall of the slot of the second slide groove 21, and help to protect the curtain 4 from being damaged during the sliding process.

[0041] In addition, refer to Figure 2The limiting convex pieces 22 are fixedly connected to the two opposite inner walls of the notches of the first slide groove 11 and the second slide groove 21. The two limiting convex pieces 22 are extended and bent toward each other, and the side walls of the edges of the limiting convex pieces 22 facing each other begin to have arc chamfers. Under the limitation of the two limiting convex pieces 22, when the curtain 4 contacts the limiting convex pieces 22 under the action of wind, it can be limited to a certain extent, is not prone to large-scale shaking, and is not easy to scratch the curtain 4.

[0042] Reference Figure 1 and Figure 2 A reinforcing connecting plate 3 is also provided between the first rail 1 and the second rail 2. The reinforcing connecting plate 3 includes a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is fixedly connected to the upper surface of the rear side wall of the first rail 1 and extends toward the upper side. The second connecting portion 32 is fixedly connected to the left side wall of the first connecting portion 31, and the right side wall of the second rail 2 is fixedly connected to the left side wall of the second connecting portion 32, so that the strength of the connecting structure between the first rail 1 and the second rail 2 is increased.

[0043] In addition, it is necessary to further explain that the second connection part 32 includes a first fixing plate 321 and a second fixing plate 322, and the second fixing plate 322 is located on the upper side wall of the first fixing plate 321, so that the first fixing plate 321 and the second fixing plate 322 are arranged at intervals in the vertical direction, and the right side walls of the first fixing plate 321 and the second fixing plate 322 are fixedly connected to the left side wall of the first connection part 31, and the left side walls of the first fixing plate 321 and the second fixing plate 322 are fixedly connected to the second track 2. The first fixing plate 321 and the second fixing plate 322 are respectively connected to positions of different heights on the right side wall of the second track 2, so that the contact area between the second track 2 and the second connection part 32 is increased, which helps to further increase the connection firmness between the second track 2 and the second connection part 32.

[0044] Reference Figure 2 The left side wall of the first track 1 is fixedly connected with a first hanging part 12, and the first hanging part 12 begins to have a hanging groove 121, and the hanging groove 121 is for an external rivet to be embedded, so as to fix the first hanging part 12. The first hanging part 12 and the lower side edge side wall of the second track 2 are spaced to form a first light strip groove 13, and the first light strip groove 13 is for an external light strip to be embedded and installed, so that the curtain 4 hanging from the second slide groove 21 is illuminated by the light strip in the first light strip groove 13, thereby increasing the ambient lighting effect of the curtain 4 and playing a better decorative role.

[0045] In order to further increase the number of light strips that can be installed to achieve more diverse lighting effects, when the first fixing plate 321 extends toward the left, a recessed second light strip groove 23 is formed with the side wall of the upper edge of the second track 2 close to the left side for additional light strips to be embedded and installed.

[0046] In addition, in order to provide a certain installation structure when the first connecting part 31 is installed and fixed to the wall, a second hanging part 33 is fixed to the right side wall of the first connecting part 31. The structure of the second hanging part 33 is the same as that of the first hanging part 12, and is used for external rivets to be embedded and fixedly connected.

[0047] In the first embodiment of the present application, the implementation principle of a track structure using a double-layer curtain is as follows: by fixing the second track 2 on the upper right side of the first track 1, and making the second slide groove 21 open toward the lower left, so that when the double-layer curtain is installed, the space occupied in the left and right horizontal directions can be reduced, thereby being able to adapt to the installation environment with a relatively small horizontal space, and friction contact is less likely to occur between the double-layer curtains, which helps to extend the service life of the curtains.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
