Description

Technical Field

[0001] This utility model relates to the technical field of home furnishings, and in particular to a composite curtain track. Background Technology

[0002] Existing curtain tracks are mainly made of metal and PVC. For example, there's a double-track composite curtain track (technical announcement number CN221469634U). While PVC tracks are cheaper, they lack strength and are prone to deformation or cracking during operation, affecting their lifespan. Furthermore, traditional track designs have shortcomings in both fixing and sliding performance, resulting in a poor user experience. Therefore, there is an urgent need for a composite curtain track that combines high strength, low cost, and easy installation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a high-strength and low-cost composite curtain track.

[0004] This utility model discloses a composite curtain track, comprising a PVC profile and a first reinforcing rib. The PVC profile is hollow, with multiple sets of first reinforcing ribs inside. The bottom end of the PVC profile has two openings, with a first L-shaped groove and a second L-shaped groove on each side of the bottom end of the openings. The two sets of second L-shaped grooves are located between the two sets of first L-shaped grooves. The bottom end of the PVC profile also has a first dovetail-shaped groove. The track further includes a first carbon steel profile assembly and a second carbon steel profile assembly. The first carbon steel profile assembly cooperates with the two sets of first L-shaped grooves to support the PVC profile. The top of the profile and the front and rear ends of the PVC profile are wrapped. The No. 2 carbon steel profile assembly, with the cooperation of two sets of No. 2 L-shaped grooves, wraps the bottom end of the PVC profile. The No. 1 carbon steel profile assembly, with the cooperation of two sets of No. 1 L-shaped grooves, wraps the top of the PVC profile and the front and rear ends of the PVC profile. The No. 2 carbon steel profile assembly, with the cooperation of two sets of No. 2 L-shaped grooves, wraps the bottom end of the PVC profile. This retains the lightness of PVC while using carbon steel to enhance the overall strength, avoiding cracking and deformation problems, significantly reducing the cost of carbon steel materials, and simplifying the production process.

[0005] Preferably, the No. 1 carbon steel profile assembly includes a U-shaped carbon steel profile and a No. 1 plate-shaped carbon steel profile. A set of No. 1 plate-shaped carbon steel profiles is respectively set at the bottom of both sides of the U-shaped carbon steel profile. The U-shaped carbon steel profile is compatible with the PVC profile. In use, the U-shaped carbon steel profile is wrapped around the top and front and rear ends of the PVC profile while the two sets of No. 1 plate-shaped carbon steel profiles are slid into a set of No. 1 L-shaped grooves, thereby completing the installation of the U-shaped carbon steel profile. The operation is simple and convenient.

[0006] Preferably, the No. 2 carbon steel profile assembly includes a No. 2 plate-shaped carbon steel profile and a No. 2 dovetail-shaped groove. The bottom end of the No. 2 plate-shaped carbon steel profile is provided with a No. 2 dovetail-shaped groove, which is compatible with the No. 1 dovetail-shaped groove. In use, when the No. 2 plate-shaped carbon steel profile wraps around the bottom end of the PVC profile, both ends of the No. 2 plate-shaped carbon steel profile slide into the two sets of No. 2 L-shaped grooves respectively, and the No. 2 dovetail-shaped groove slides into the No. 1 dovetail-shaped groove, thereby completing the installation of the No. 2 plate-shaped carbon steel profile. The operation is simple and convenient.

[0007] Preferably, it also includes a second reinforcing rib, which is provided inside the PVC profile; the second reinforcing rib supports the first dovetail groove inside the PVC profile, reducing deformation and improving stability.

[0008] Preferably, it also includes protrusions, with a set of protrusions on the left and right sides of the top of each set of openings; the protrusions limit the wheels in the slide, preventing them from detaching from the PVC profile when the wheels move the curtain.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the No. 1 carbon steel profile component, together with two sets of No. 1 L-shaped grooves, wraps the top and front and rear ends of the PVC profile; the No. 2 carbon steel profile component, together with two sets of No. 2 L-shaped grooves, wraps the bottom end of the PVC profile. This not only preserves the lightness of PVC, but also enhances the overall strength with carbon steel, avoiding cracking and deformation problems, greatly reducing the cost of carbon steel materials, and simplifying the production process.

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example

[0015] like Figures 1 to 3 As shown, this utility model discloses a composite curtain track, including a PVC profile 1 and a first reinforcing rib 2. The PVC profile 1 is hollow, and multiple sets of first reinforcing ribs 2 are provided inside the PVC profile 1. The bottom end of the PVC profile 1 is provided with two sets of openings 3. On both sides of the bottom end of the openings 3, a first L-shaped groove 4 and a second L-shaped groove 5 are respectively provided. The two sets of second L-shaped grooves 5 are between the two sets of first L-shaped grooves 4. The bottom end of the PVC profile 1 is provided with a first dovetail groove 6. It also includes a first carbon steel profile assembly and a second carbon steel profile assembly. The first carbon steel profile assembly cooperates with the two sets of first L-shaped grooves 4 to wrap the top end and the front and rear ends of the PVC profile 1. The second carbon steel profile assembly, with the cooperation of the two sets of second L-shaped grooves 5, wraps the bottom end of the PVC profile 1.

[0016] The No. 1 carbon steel profile assembly includes a U-shaped carbon steel profile 7 and a No. 1 plate-shaped carbon steel profile 8. A set of No. 1 plate-shaped carbon steel profiles 8 are respectively set at the bottom of the two sides inside the U-shaped carbon steel profile 7. The U-shaped carbon steel profile 7 is compatible with the PVC profile 1.

[0017] The No. 2 carbon steel profile assembly includes a No. 2 plate-shaped carbon steel profile 9 and a No. 2 dovetail groove 10. The bottom end of the No. 2 plate-shaped carbon steel profile 9 is provided with a No. 2 dovetail groove 10, which is compatible with the No. 1 dovetail groove 6.

[0018] It also includes a second reinforcing rib 11 and a protrusion 12. The PVC profile 1 is provided with a second reinforcing rib 11 inside, and a set of protrusions 12 are provided on the left and right sides of the top of each set of openings 3.

[0019] In this embodiment, during use, while wrapping the top and front and rear ends of the PVC profile 1 with the U-shaped carbon steel profile 7, two sets of No. 1 plate-shaped carbon steel profiles 8 are slid into a set of No. 1 L-shaped grooves 4, thereby completing the installation of the U-shaped carbon steel profile 7. When wrapping the bottom end of the PVC profile 1 with the No. 2 plate-shaped carbon steel profile 9, both ends of the No. 2 plate-shaped carbon steel profile 9 are slid into two sets of No. 2 L-shaped grooves 5, and the No. 2 dovetail groove 10 is slid into the No. 1 dovetail groove 6, thereby completing the installation of the No. 2 plate-shaped carbon steel profile 9. This retains the lightness of PVC while using carbon steel to enhance the overall strength.

[0020] This utility model discloses a composite curtain track in which a U-shaped carbon steel profile 7 is integrally formed with a first-plate carbon steel profile 8, and a second-plate carbon steel profile 9 is integrally formed with a second-dovetail groove 10.
