Description

Technical Field

[0001] This utility model belongs to the field of curtains, specifically relating to a nail-free curtain track installation code. Background Technology

[0002] Currently, there are various installation methods for simple roller blinds on the market, but the mounting brackets for nail-free PVC tracks cannot be directly inserted into the track slots. They require slots to be cut into the brackets to slide the brackets in from the side, increasing both installation difficulty and bracket costs, as seen in patent CN209807965U's structure for a curtain track assembly. Patent CN220089187U presents a novel curtain track installation structure, which, while convenient for installation and disassembly, has a complex overall structure and high cost. There is a need for a mounting bracket that can be simply inserted into the track slots. Summary of the Invention

[0003] This utility model provides a nail-free curtain track mounting bracket.

[0004] The purpose of this utility model is achieved in the following manner: a nail-free curtain track mounting bracket includes a hook for engaging with the track and a mounting insert for installation. The front of the hook is provided with a mounting groove for engaging the track. The opening end of the mounting groove faces the track, and the height of the bottom surface of the mounting groove is greater than the height of the opening end. An arc-shaped groove is provided on the bottom surface of the mounting groove along its own height direction, extending away from the opening end. The portion of the bottom surface of the mounting groove above and below the arc-shaped groove is flat and respectively connects with the two ends of the arc-shaped groove.

[0005] The back of the hook away from the track has the following characteristics: the shape corresponding to the position of the arc groove is an arc surface, and the shape corresponding to the upper and lower ends of the mounting slot is a plane that aligns with the upper and lower ends of the arc groove.

[0006] The length of the arc-shaped groove is the same as the length of the hook; the width of the portion of the hook corresponding to the arc-shaped groove is not greater than the width of the remaining portion.

[0007] The hook has at least two parallel vertical reinforcing ribs on its back.

[0008] The height of the arc-shaped groove is not less than half the height of the mounting slot; the arc-shaped groove is located within the range of the bottom surface of the mounting slot corresponding to the open end of the mounting slot.

[0009] The bottom surface of the mounting slot has protrusions on the planes above and below the arc-shaped groove, and the contact surfaces of the two protrusions with the track are on the same plane.

[0010] The hook has a handle at its lower end, and the upper end of the handle is connected to a baffle at the lower end of the opening.

[0011] The upper end of the hook is detachably connected to the insert, and the distance between the mounting ends of the hook and the insert is adjustable.

[0012] Compared to existing technologies, this invention features an arc-shaped groove along the height of the mounting slot. When pressed, the back of the arc-shaped groove exhibits a certain degree of elasticity, causing the arc portion to become smaller and flatter, thus increasing the height of the bottom surface of the mounting slot and facilitating the hook's engagement with the track. For disassembly, pressing the arc-shaped groove again allows for easy removal of the hook from the track. This invention boasts a simple structure and convenient installation and disassembly operations. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Figure 1-5As shown, a nail-free curtain track 1 mounting bracket includes a hook 2 for engaging with the track 1 and an insert 7 for installation. The hook 2 has a mounting groove 4 on its front for engaging the track 1. The opening end of the mounting groove 4 faces the track 1, and the height of the bottom surface of the mounting groove 4 is greater than the height of the opening end. An arc-shaped groove 40 is recessed along its height direction away from the opening end on the bottom surface of the mounting groove 4. The portion of the bottom surface of the mounting groove 4 above and below the arc-shaped groove 40 is flat and respectively aligns with both ends of the arc-shaped groove 40. In this invention, when the hook 2 is vertically installed on the track 1, the direction parallel to the length direction of the track 1 is the length direction of the hook 2; the vertical direction, which is parallel to the height direction of the track 1, is the height direction of the hook 2; and the other direction is the width direction. In this invention, the structure of the hook 2 and the insert 7 can be designed as needed, and can be a separate structure or an integrated structure, as long as it can connect to the track 1 and fix the curtain with the track 1 to the wall or other suitable location. Existing technologies can be used. The arc-shaped groove 40 on the mounting slot 4 is set along its own height direction, meaning the longitudinal section of the arc-shaped groove 40 is arc-shaped. In this invention, the arc-shaped groove 40 is set in the height direction of the mounting slot 4. When the back of the arc-shaped groove 40 is pressed, it has a certain degree of extensibility, the arc of the arc-shaped part becomes smaller and flatter, and the height of the bottom surface of the mounting slot 4 increases, thus facilitating the hook 2 to engage with the track 1. When disassembly is required, pressing the arc-shaped groove 40 again allows the hook 2 to be easily removed from the track 1. Moreover, in this invention, the bottom surfaces corresponding to the upper and lower ends of the arc-shaped groove 40 are flat, and the arc-shaped groove 40 occupies the middle position in the height direction of the bottom surface of the mounting slot 4, not the entire height direction. In this case, after installation, the arc-shaped groove 40 on the bottom surface of the mounting slot 4 does not contact the track 1, but the bottom surface above and below the arc-shaped groove 40 can contact the track 1, thereby achieving close contact between the hook 2 and the track 1 and preventing relative movement of the two after being subjected to force.

[0021] Furthermore, the back of the hook 2 away from the track 1 has an arc-shaped surface corresponding to the position of the arc-shaped groove 40, and the upper and lower ends of the mounting slot 4 are flat surfaces that align with the upper and lower ends of the arc-shaped groove 40. The hook 2 in the portion corresponding to the arc-shaped groove 40 has an overall arc-shaped structure, which, compared to a structure with an arc-shaped front and a flat back, allows for easier elastic deformation when pressed and is less likely to damage the material.

[0022] Preferably, the length of the arc-shaped groove 40 is the same as the length of the hook 2; the width of the portion of the hook 2 corresponding to the arc-shaped groove 40 is not greater than the width of the remaining portion. The length of the arc-shaped groove 40 occupies the entire length of the hook 2, which firstly facilitates the manufacturing process and secondly improves the extension performance. The width of the arc-shaped groove 40 being no greater than the width of the remaining portion further improves the extension performance, making it easier to extend by pressing, thereby facilitating installation and disassembly.

[0023] Furthermore, at least two parallel vertical reinforcing ribs 5 are provided on the back of the hook 2. In a preferred embodiment, one vertical reinforcing rib 5 is provided at each end of the length direction of the hook 2, and another vertical reinforcing rib 5 is provided at the middle position of the length direction of the hook 2. Providing the vertical reinforcing ribs 5 can increase strength while retaining good elastic deformation capacity, thereby extending the service life of the hook 2.

[0024] Preferably, the height of the arc-shaped groove 40 is not less than half the height of the mounting slot 4; the arc-shaped groove 40 is located within the range of the bottom surface of the mounting slot 4 corresponding to the open end of the mounting slot 4. Preferably, the arc-shaped groove 40 is located at the middle position in the height direction of the mounting slot 4. If the height of the arc-shaped groove 40 is too small, the extension effect will be poor.

[0025] Furthermore, the bottom surface of the mounting slot 4 is provided with protrusions 41 on the planes above and below the arc-shaped groove 40, and the contact surfaces of the two protrusions 41 with the track 1 are on the same plane. The protrusions 41 contacting the surface of the track 1 achieves the pressing of the hook 2 with the track 1, further increasing friction and preventing wobbling between them.

[0026] Preferably, a handle 6 can be provided at the lower end of the hook 2, and the upper end of the handle 6 is connected to the baffle at the lower end of the open end. Providing the handle 6 makes it easy to grip the lower end of the hook 2, thereby facilitating operation.

[0027] Furthermore, the upper end of the hook 2 is detachably connected to the insert 7, and the distance between the mounting ends of the hook 2 and the insert 7 is adjustable. Specifically, the upper end of the hook 2 can be provided with a connecting part 3, and the connecting part 3 has a through hole. The insert 7 can be L-shaped, including an upper connecting plate 71 and a lower connecting plate 72. The upper connecting plate 71 can be provided with multiple parallel connecting teeth 73, the side of the connecting teeth 73 facing the hook 2 being an inclined surface, and the side away from the hook 2 being a blocking surface; a stop groove is formed between two connecting teeth 73; a limiting member that cooperates with the connecting teeth 73 is provided in the through hole of the connecting part 3 of the hook 2; a row of connecting teeth 73 and the limiting member constitute a one-way adjustment mechanism that allows the insert 7 to move unidirectionally towards the connecting part 3, thereby adjusting the distance between the hook 2 and the insert 7. The lower connecting part 3 of the insert 7 can also be provided with similar connecting teeth 73, thereby connecting to a mounting component fixed to a wall or window frame. The structure of the insert 7 and the connection structure between the insert 7 and the connecting part 3 are existing technologies and will not be described in detail here.

[0028] In practice: Align the upper end of the mounting slot 4 of the hook 2 with the upper end of the track 1, and press down to allow the upper end of the track 1 to enter the mounting slot 4. Rotate the hook 2 so that the bottom of the mounting slot 4 aligns with the lower end of the track 1. Press down on the back of the hook 2 corresponding to the arc groove, increasing the height of the hook 2, and allowing the lower end of the track 1 to enter the mounting slot 4. Then, install the insert 7 in a suitable position on the window frame or wall, insert the hook 2 with the track 1 into the insert 7, and adjust it to the appropriate position. The entire curtain installation is now complete. For disassembly, first press down on the arc groove with one hand to increase the height of the hook 2, then hold the handle 6 or directly hold both sides of the hook 2 to remove it. Alternatively, the insert 7 can be pre-installed on the hook 2 to determine the distance, and then the entire curtain can be installed with the track 1.

[0029] The technical features of the embodiments described above can be combined in any way, and as long as there is no contradiction in the combination of these technical features, they should all be considered within the scope of this specification. Without departing from the overall concept of this utility model, any equivalent substitutions or modifications made to the technical solution of this utility model, as well as any changes and improvements, should also be considered within the protection scope of this utility model.
