Description

Technical Field

[0001] This utility model relates to the field of curtain track technology, and in particular to a double-track curtain track structure. Background Technology

[0002] Curtain tracks are essential devices for hanging and supporting curtains, and for enabling them to open and close. They play a key role in interior decoration and functionality. Single-track curtain tracks can only accommodate one layer of curtains, making them suitable for scenarios with limited window space or where only one layer of curtain is needed, such as a bedroom requiring only one blackout curtain. Double-track curtain tracks can accommodate two layers of curtains simultaneously, namely a sheer curtain and a thick curtain, ensuring both privacy and light control. They are suitable for areas such as living rooms where light control and decorative effects are important.

[0003] A search revealed Chinese patent publication number CN212089135U, which discloses an integrated, bracketless U-shaped toothed groove double track, including a mounting hole groove, a track, and a concave groove. The track has a mounting hole groove installed on the wall side, and screws are used to fix the track to the wall through the mounting hole groove. A left groove and a right groove are respectively located at the lower left and right corners of both ends of the track plane, with openings at the center of their bottom ends, the openings being closed at both ends. The left and right grooves are interconnected via the track. Pulleys are installed inside the left and right grooves to fix the curtains. A thumb-and-shoulder opening is provided on the wall side of the left and right grooves to ensure even weight distribution when curtains are installed inside the track and groove. The track is 2mm thick and 10cm long, and the track is integrated with the left and right grooves for easy curtain hanging. This utility model uses mounting holes and grooves to fix the track to the wall, allowing the track to fit perfectly against the wall for seamless sun shading. It can hang double-layer curtains and is durable. However, in actual use, the two tracks are fixed, which reduces flexibility and prevents the installation of a secondary track with a suitable width according to the window size, thus reducing the track's adaptability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a double-track curtain track structure, which aims to improve the problem in the prior art that it is impossible to install a secondary track of a suitable width according to the window size, thereby reducing the track's adaptability range.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a double-track curtain track structure, comprising two connecting shells, with bolts threadedly connected to the bottom left and right sides of both connecting shells. The top of the bolt on the left is threadedly connected to a main track, and the top of the bolt on the right is threadedly connected to a secondary track. A threaded rod is rotatably connected to the middle of the top wall of each connecting shell, and a knob is fixedly connected to the top of the threaded rod. A fixing shell is threadedly connected to the outer wall of the threaded rod. Limiting posts are fixedly connected to the left and right sides of the top wall of each connecting shell. The outer walls of the limiting posts are slidably connected to the bottom of the fixing shell. Engaging grooves are provided on the left and right sides of the bottom wall of the fixing shell. The tops of the main track and the secondary track respectively engage with the corresponding engaging grooves. A weather-resistant mechanism is provided on the inner bottom wall of the main track.

[0006] The above technical solution allows for initial installation through the engagement of the connecting shell and the double track. Subsequently, the bottom of the track is locked by rotating the bolts, and the top of the track is fixed by lowering the fixing shell. This structure enables the installation of a secondary track of appropriate width according to the window size, thus improving the flexibility of the structure.

[0007] As a further description of the above technical solution:

[0008] The weather-resistant mechanism includes a rock wool board, the bottom wall of which is fixedly connected to the inner bottom wall of the main track, a gel board fixedly connected to the top wall of the rock wool board, a connecting frame fixedly connected to the top of the gel board, a polymer waterproof board fixedly connected to both the left and right sides of the connecting frame, and multiple pressure-resistant pads fixedly connected at equal intervals to the top wall of the polymer waterproof board.

[0009] The above technical solution effectively improves the fire resistance and heat insulation of the bottom of the main track by connecting the rock wool board and the gel board. Subsequently, multiple pressure-resistant pads enhance the internal pressure resistance of the main track. At the same time, the connection between the polymer waterproof board and the rock wool board improves the weather resistance of the main track and increases its service life.

[0010] As a further description of the above technical solution:

[0011] The weather-resistant mechanism also includes a silicone sealant layer, the top wall of which is fixedly connected to the inner top wall of the main track.

[0012] The above technical solution improves the sealing performance inside the main track by connecting the silicone sealant layer.

[0013] As a further description of the above technical solution:

[0014] Two locking slots are provided on the opposite sides of the main track and the auxiliary track. Locking plates are rotatably connected to the left and right sides of the connecting shell, and the top of the locking plates engages with the locking slots.

[0015] The above technical solution improves the stability of the outer sides of the main track and the auxiliary track by engaging the locking plate and the locking groove.

[0016] As a further description of the above technical solution:

[0017] Each of the bolts has a rubber ring fixedly connected to its center, and the rubber rings are all designed symmetrically.

[0018] The above technical solution reduces rotational damage to the bottom of the connecting shell caused by the bolts, thanks to the connection of the rubber ring.

[0019] As a further description of the above technical solution:

[0020] Multiple rubber pillars are fixedly connected to the outer walls of both knobs, and the multiple rubber pillars are connected in an equidistant ring.

[0021] The above technical solution improves the protection of the outer wall of the knob by connecting the rubber column.

[0022] As a further description of the above technical solution:

[0023] A handle is fixedly connected to the front side of each of the two connecting shells, and a rubber sleeve is fixedly connected to the middle of the handle.

[0024] The above technical solution improves the anti-slip effect of the grip when using the handle by connecting the rubber sleeve.

[0025] As a further description of the above technical solution:

[0026] The size of the locking groove matches the top of the corresponding main track and the secondary track, and the opposite sides of the multiple locking plates are all designed with a smooth surface.

[0027] The above technical solution improves the structural toughness by using a smooth design on the outer side of multiple locking plates.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a double-track curtain track structure, comprising two connecting shells 1. Bolts 3 are threadedly connected to the left and right sides of the bottom of each connecting shell 1, locking the bottom of the main track 4 and the secondary track 5 to the connecting shells 1 via the bolts 3. The top of the left bolt 3 is threadedly connected to the main track 4, and the top of the right bolt 3 is threadedly connected to the secondary track 5. A threaded rod 8 is rotatably connected to the center of the top wall of the connecting shell 1, and a knob 9 is fixedly connected to the top of the threaded rod 8. Rotation of the knob 9 causes the threaded rod 8 to rotate, thereby... With the connection of the limiting post 14, the fixed shell 11 can be raised and lowered. The outer wall of the threaded rod 8 is threadedly connected to the fixed shell 11. The left and right sides of the top wall of the connecting shell 1 are fixedly connected to the limiting post 14. The outer wall of the limiting post 14 is slidably connected to the bottom of the fixed shell 11. The left and right sides of the bottom wall of the fixed shell 11 are provided with engagement grooves 12, so that the fixed shell 11 can be engaged and installed with the top of the main track 4 and the auxiliary track 5. The top of the main track 4 and the auxiliary track 5 are engaged with the corresponding engagement grooves 12 respectively. The inner bottom wall of the main track 4 is provided with a weather-resistant mechanism 2.

[0040] Specifically, threaded holes are provided on the left and right sides of the bottom of both connecting shells 1 for threaded connection with bolts 3. By tightening bolts 3, the bottom of the main track 4 and the auxiliary track 5 can be securely locked to the connecting shell 1. The top of bolt 3 on the left is threaded to the threaded hole at the bottom of the main track 4, and the top of bolt 3 on the right is threaded to the threaded hole at the bottom of the auxiliary track 5. A rotating connection structure is provided in the middle of the top wall of the connecting shell 1, through which the threaded rod 8 can be rotatably installed. The top of the threaded rod 8 is fixedly connected to a knob 9. When the operator rotates the knob 9, the threaded rod 8 rotates synchronously. Since limit posts 14 are fixedly connected to the left and right sides of the top wall of the connecting shell 1, and the outer wall of the limit post 14 is fixed to the fixed shell... The sliding hole at the bottom of the fixed shell 11 is adapted to form a sliding connection. Therefore, when the threaded rod 8 rotates, the fixed shell 11 will not rotate with the threaded rod 8 under the limiting action of the limiting post 14. Instead, it will move up and down along the outer wall of the limiting post 14. The bottom wall of the fixed shell 11 is provided with locking grooves 12 on the left and right sides respectively. When the fixed shell 11 descends, the tops of the main track 4 and the auxiliary track 5 can be respectively inserted into the corresponding locking grooves 12, thereby completing the locking installation of the fixed shell 11 with the tops of the main track 4 and the auxiliary track 5, and realizing further fixing and positioning of the main track 4 and the auxiliary track 5. In addition, the inner bottom wall of the main track 4 is provided with a weather-resistant mechanism 2 to enhance the performance of the main track 4 in different climatic environments.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The weather-resistant mechanism 2 includes a rock wool board 201. The bottom wall of the rock wool board 201 is fixedly connected to the inner bottom wall of the main track 4. The connection of the rock wool board 201 improves the fire resistance of the bottom of the main track 4. A gel board 202 is fixedly connected to the top wall of the rock wool board 201. A connecting frame 203 is fixedly connected to the top of the gel board 202. The gel board 202 improves the heat insulation effect inside the main track 4. Polymer waterproof boards 204 are fixedly connected to both sides of the connecting frame 203. The connection of the two polymer waterproof boards 204 improves the overall weather resistance inside the main track 4, thereby improving the service life of the main track 4. Multiple pressure-resistant pads 205 are fixedly connected at equal intervals to the top wall of the polymer waterproof board 204.

[0042] Specifically, the combination of rock wool board 201 and gel board 202 effectively reinforces the bottom of the main track 4, thereby improving its fire resistance and heat insulation effect, and enhancing the weather resistance of the main track 4. With the joint action of connecting frame 203 and multiple pressure pads 205, the top of the inner wall of the main track 4 is reinforced against pressure, improving the stability of the structure and ensuring the reliability of the track under heavy load. The introduction of polymer waterproof board 204 provides more waterproof protection for the track 4, effectively preventing water from eroding and damaging the track. The overall weather resistance of the main track 4 is improved, thereby extending its service life.

[0043] Reference Figure 1 , Figure 3 and Figure 4 The weather-resistant mechanism 2 also includes a silicone sealant layer 206, the top wall of which is fixedly connected to the inner top wall of the main track 4; two locking grooves 6 are opened on the opposite side of the main track 4 and the auxiliary track 5; locking plates 7 are rotatably connected to the left and right sides of the connecting shell 1, and the top of the locking plates 7 engages with the locking grooves 6; rubber rings 13 are fixedly connected to the middle of multiple bolts 3, and the multiple rubber rings 13 are symmetrically designed;

[0044] Specifically, the connection of the silicone sealant layer 206 improves the sealing of the top of the inner wall of the main track 4. The engagement of multiple locking plates 7 with the corresponding locking grooves 6 improves the stability of the track during fixing. The connection of the rubber ring 13 reduces the rotational damage of the bolt 3 to the connecting shell 1.

[0045] Reference Figure 2 and Figure 4 Multiple rubber pillars 10 are fixedly connected to the outer walls of the two knobs 9, and the multiple rubber pillars 10 are connected in an equidistant ring; a handle 15 is fixedly connected to the front side of the two connecting shells 1, and a rubber sleeve 16 is fixedly connected to the middle of the handle 15; the size of the locking groove 12 matches the top of the corresponding main rail 4 and the auxiliary rail 5, and the opposite side of the multiple locking plates 7 is designed to be smooth.

[0046] Specifically, the fixed connection of multiple rubber pillars 10 improves the protection of the outer wall of the knob 9, the connection of rubber sleeves 16 improves the anti-slip effect of the grip 15 when using it, and the smooth design of the opposite side of multiple locking plates 7 improves the toughness of the outer wall of the locking plate 7.

[0047] Working principle: During initial installation, the main track 4 and the secondary track 5 are respectively engaged with the left and right sides of the top wall of the connecting shell 1, thus completing the initial installation of the tracks. Then, by rotating the bolt 3 upwards, the bottom of the main track 4 and the secondary track 5 can be locked. Then, by rotating the knob 9, the threaded rod 8 is rotated, so that the fixed shell 11 can be lowered under the restriction of the rotation of the limiting post 14. Then, the top of the main track 4 and the secondary track 5 is fixed, so as to achieve the purpose of flexible installation of double-track curtain tracks. This allows the structure to install a secondary track 5 of appropriate width according to the window size, improving the flexibility of the structure and achieving the effect of easy carrying and installation.

[0048] Furthermore, the connection between the rock wool board 201 and the gel board 202 enhances the fire resistance and heat insulation of the bottom of the main track 4, thereby improving its weather resistance. Subsequently, the connection between the connecting frame 203 and multiple pressure-resistant pads 205 increases the pressure resistance of the top inner wall of the main track 4. At the same time, the connection with the polymer waterproof board 204 further improves the waterproof effect of the main track 4, thereby increasing the weather resistance of the main track 4 and extending its service life.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
