In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0041] The main purpose of the utility model is to provide a novel curtain guide rail, aiming to solve the problems that the existing curtain guide rail is difficult to bend and the pulley is easy to get stuck when traveling.

[0042] The present application provides a novel curtain rail, comprising a first rail 1, a second rail 2, and a rail connector 3 connecting the first rail 1 and the second rail 2. The first rail 1, the second rail 2, and the rail connector 3 are all independent structures and are assembled when the rails need to be installed.

[0043] The first guide rail 1 and the second guide rail 2 are both provided with a bent bottom frame 5 at the bottom, a top protrusion 31 is provided on the upper part of the guide rail connector 3, a first protrusion 32 and a second protrusion 33 are respectively provided on both sides of the top protrusion 31, a groove is formed between the top protrusion 31 and the first protrusion 32, and between the top protrusion 31 and the second protrusion 33, a bottom protrusion 34 is provided at the lower part of the guide rail connector 3, a bottom groove 341 is provided in the middle of the bottom protrusion 34, a third protrusion 35 and a fourth protrusion 36 are respectively provided on both sides of the bottom protrusion 34, a groove is formed between the bottom protrusion 34 and the third protrusion 35, and between the bottom protrusion 34 and the fourth protrusion 36, the first guide rail 1 is provided with a left engaging groove 11 matching the first protrusion 32 and the third protrusion 35, and the second guide rail 2 is provided with a right engaging groove 21 matching the second protrusion 33 and the fourth protrusion 36. The left engaging groove 11 and the right engaging groove 21 are respectively engaged with the guide rail connector 3 , so that a stable connection between the guide rail and the guide rail connector 3 can be ensured.

[0044] In some specific implementations, the first guide rail 1 and the second guide rail 2 are symmetrical structures, which means that only one side of the guide rail can be produced, and the guide rail on the other side can be obtained by intercepting the produced guide rail, which saves a lot of mold costs and improves production efficiency. The first guide rail 1, the second guide rail 2, and the guide rail connector 3 can be made of resin, plastic, metal and other materials. The preferred solution is that the first guide rail 1 and the second guide rail 2 are made of aluminum alloy, and the guide rail connector 3 can be made of PVC plastic material with good deformation ability and strength performance.

[0045] The product of the present application can certainly be used in straight-line scenes, and can also be well suited for scenes that require turning. During the construction and installation process, the middle part of the curtain rail uses plastic with good deformation ability, and the construction personnel can bend it after assembling the curtain rail. Due to the unique combined structure, the bending process is not easy to cause abnormal deformation of the metal and affect the use. The product of the present application generally needs to be fixed with screws or other devices. When using screws for fixing, the screws can be aligned with the middle of the bottom groove 341 of the guide rail connector 3 for fixing. The screws will penetrate the guide rail connector 3 from bottom to top and be driven into the wall. After the installation is completed, due to the presence of the bottom groove 341, the nut part of the screw can penetrate into the interior of the bottom groove 341, that is, the bottom end of the nut will not exceed the bottom end of the bottom protrusion 34, and no abnormal protrusion will be generated to affect the normal travel of the pulley at the lower end.

[0046] In some specific embodiments, in order to enable construction workers to better find the middle of the bottom groove 341, a top wire groove 311 may be provided on the top protrusion 31, and a bottom wire groove 342 may be provided on the bottom groove 341. The top wire groove 311 and the bottom wire groove 342 may be provided separately or together. When in use, the construction worker may drive the screw into the guide rail connector 3 with the tip of the screw vertically aligned with the wire groove.

[0047] In some specific embodiments, the first guide rail 1 and the second guide rail 2 are both provided with a bent top frame 4 at the top, the upper wall of the bottom frame 5 of the first guide rail 1 and the second guide rail 2 are both provided with an upper wall protrusion 51, and the lower wall of the bottom frame 5 of the first guide rail 1 and the second guide rail 2 are both provided with a lower wall protrusion 52. The upper wall protrusion 51 and the lower wall protrusion 52 can physically separate the bottom frame 5 into different functional areas. Taking the first guide rail 1 as an example, the upper wall protrusion 51 where the first guide rail 1 is located, the inner side of the bottom frame 5, and the lower wall protrusion 52 form a belt groove 7. The lower end of the guide rail connector 3, the two upper wall protrusions 51 and the two lower wall protrusions 52 form a pulley groove. The lower end of the upper wall protrusion 51 does not contact the upper end of the lower wall protrusion 52, but in some other embodiments, the upper wall protrusion 51 and the lower wall protrusion 52 can be connected up and down to form a closed whole.

[0048] In some specific embodiments, the belt groove 7 formed by the upper wall protrusion 51, the inner side of the bottom frame 5, and the lower wall protrusion 52 has parallel linear patterns 71 arranged along the length direction. The linear patterns 71 can reduce the friction of the belt, making the belt movement smoother, and can also play a role in silencing noise to a certain extent. The linear patterns 71 are preferably arranged as sawtooth patterns or wavy patterns.

[0049] In some specific embodiments, the lower wall of the base frame 5 of the first guide rail 1 and the second guide rail 2 is provided with a silent rail 6. The silent rail 6 can be laid only on the track where the pulley passes, that is, only on the lower wall portion of the base frame 5. In some other specific embodiments, the silent rail 6 is in an "L"-shaped structure, the vertical portion of the silent rail 6 is in contact with the lower wall protrusion 52, the horizontal portion of the silent rail 6 is laid on the lower wall of the base frame 5, and the lower wall protrusion 52 and at least a portion of the lower wall of the base frame 5 form a folding structure for engaging the silent rail 6. Specifically, the upper end of the lower wall protrusion 52 has a rotation angle for folding the silent rail 6, and the lower end of the lower wall protrusion 52 has a groove at a right angle for folding the silent rail 6, and the silent rail 6 can be provided with a protruding structure to better achieve a fixing effect. The silent rail 6 can be made of resin, plastic material or other shock-absorbing materials with a small friction coefficient.

[0050] In some specific embodiments, at least a portion of the horizontal direction of the silent rail 6 forms a folding structure that engages with the lower wall of the base frame 5. Specifically, the end of the silent rail 6 in the horizontal direction has a bending and rotating structure, which cooperates with the protruding structure at the right angle of the silent rail 6 to achieve a gripping and fixing effect. When installing the silent rail 6, one end of the silent rail 6 can be inserted into the folding structure formed by the lower wall protruding piece 52 and at least a portion of the lower wall of the base frame 5, and external force is continuously applied to push it inward, so that the portion of the guide rail where the pulley passes is completely covered by the silent rail 6.

[0051] In some specific embodiments, the upper part of the top frame 4 is also provided with a top frame extension plate 41 arranged horizontally outward. The top frame extension plate 41 can be used to cooperate with other fixing devices to fix the guide rail to the wall, or it can be directly installed and engaged in the wall as an embedded structure.

[0052] In some specific embodiments, the lower part of the bottom frame 5 is further provided with a bottom frame extension plate 53 arranged outward in the horizontal direction. The bottom frame extension plate 53 can be used to cooperate with other fixing devices to fix the guide rail to the wall, or can be directly installed and snapped into the wall as an embedded structure. The bottom frame extension plate 53 can cover the bonding parts of cement and the like, improve the appearance of the product, and can also receive the fallen mud and plaster.

[0053] In some specific embodiments, the outer surfaces of the first guide rail 1 and the second guide rail 2 away from the guide rail connector 3 are provided with a mosaic pattern 8. The mosaic pattern 8 is used to cooperate with the wall or other fixing devices to enhance the fixing effect and ensure the stability of the guide rail. The mosaic pattern 8 is preferably a sawtooth pattern or a wavy pattern parallel to the length direction of the guide rail.

[0054] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
