Abstract
Description
Technical Field
[0001] This utility model relates to the field of home furnishing technology, specifically to a connecting piece for connecting and splicing curtain rod tracks, and a curtain rod using the connecting piece. Background Technology
[0002] Currently, curtain rods are widely used for hanging curtains in homes and offices. To accommodate windows of different widths, interlocking track curtain rods have become a common choice. Traditional interlocking track curtain rods typically consist of two or more rods joined together, secured and length-adjustable by internal springs or clips. However, the connection strength and stability of this structure are often insufficient, making it prone to loosening, slippage, or even bending and deformation under prolonged use or when hanging heavy curtains. Furthermore, existing connection methods do not adequately consider the smooth rolling or sliding of curtain fasteners (or curtain rings) at the joints, easily causing jamming and affecting the opening and closing of the curtains.
[0003] Therefore, there is an urgent need for a connection structure that can provide a secure connection while ensuring that the curtain fasteners roll or slide smoothly. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a connecting piece for splicing track curtain rods that has a reasonable structure, a stable connection, and can ensure that the curtain buckle rolls or slides smoothly.
[0005] Another objective of this invention is to provide a curtain rod whose length is flexibly adjustable, which is formed by connecting the aforementioned connecting pieces.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A connecting piece for splicing track curtain rods includes a connecting piece body. The connecting piece body has an elongated strip structure that is open at the bottom and closed at the top.
[0007] The lower opening is formed by two symmetrically arranged grooved surround strips, and the two surround strips form a cavity for accommodating the curtain buckle and allowing it to roll or slide.
[0008] The surrounding strip is divided into three sections from top to bottom: an upper surrounding strip, a middle surrounding strip, and a lower surrounding strip. The upper surrounding strip is perpendicular to the horizontal plane, and its lower end is connected to the upper end of the middle surrounding strip. The middle surrounding strip is inclined at an angle relative to the horizontal plane, and its tail end is connected to the upper end of the lower surrounding strip. The lower surrounding strip is perpendicular to the horizontal plane and extends into the cavity.
[0009] A boss is provided on the side of the elongated top. This boss is used to abut against the retaining strip inside the curtain rod during installation, thereby firmly fixing the connecting piece inside the curtain rod.
[0010] At both ends of the upper plane of the elongated top, a pair of protrusions are symmetrically arranged. Within the projection area of the upper plane corresponding to each protrusion, several screw holes are provided for fixing the connecting piece to the curtain rod by drilling screws.
[0011] As a further improvement of this utility model, the inner surface of the middle surrounding strip is provided with an inclined surface near its end. This inclined surface serves as a transition surface when the curtain buckle rolls or slides, allowing the curtain buckle to enter and leave the connecting piece area more smoothly and avoiding jamming.
[0012] As a further improvement of this utility model, a step is provided extending upward from the boss. This step structure is used to better match the curvature inside the curtain rod, increase the contact area, and improve the tightness and stability of the connection.
[0013] As a further improvement of this utility model, a total of 4 screw holes are provided, evenly distributed, that is, in pairs, each used to connect two mating spliced curtain rods, thereby achieving a firm connection between the two curtain rods.
[0014] A type of curtain rod is composed of several sections of spliced track curtain rods connected together. Its key feature is that they are connected by connecting pieces as described in any of the above schemes, so that the curtain rod can be flexibly extended to the corresponding length according to the actual width requirements of the window.
[0015] The beneficial effects of this utility model are as follows: 1. Stable connection: Through the cooperation between the first boss and the internal retaining strip of the curtain rod, and the tightening of the screw holes on the second boss, multiple fixation is achieved between the connecting piece and the curtain rod, as well as between the two curtain rods, which greatly improves the mechanical strength and stability of the connection and effectively prevents loosening and slippage.
[0016] 2. Smooth Rolling or Sliding: The unique cavity structure composed of three sections (upper, middle, and lower surround strips) provides a continuous and smooth rolling or sliding track for the curtain fasteners. In particular, the tilt angle of the middle surround strip and the transition slope design at its ends ensure that the curtain fasteners can smoothly transition when passing through the joints without any jamming.
[0017] 3. Reasonable structure and easy installation: The overall structure is cleverly designed, and the functions of each component are clearly defined. During installation, simply insert the connecting piece into the curtain rod, utilize its self-positioning structure, and then drill holes and screw in the screws. The operation is simple.
[0018] 4. High adaptability: The connecting piece of this utility model can be used to connect multiple sections of spliced track curtain rods, easily extending the total length of the curtain rod to meet the needs of windows of different sizes, and has strong versatility.

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] See Figures 1 to 4 As shown, this utility model discloses a connecting piece for splicing track curtain rods, the main body of which is a long strip-shaped connecting piece body 1 made of metal or high-strength engineering plastic. The top of the body 1 is closed and the bottom is open.
[0024] The lower opening consists of two sets of symmetrical grooved surround strips, forming a complete cavity 2 inside which the curtain fastener (not shown in the figure) can roll or slide. Each side of the surround strip is divided into three sections: an upper surround strip 3 perpendicular to the horizontal plane, a middle surround strip 4 at a certain angle, and a lower surround strip 5 extending vertically into the cavity 2. This three-section structure guides and constrains the rolling or sliding path of the curtain fastener.
[0025] On the inner surface of the central band strip 4, near its end, there is an inclined surface 9. This inclined surface 9 serves as a guide surface, allowing the curtain fastener to smoothly transition when rolling into or out of the connecting piece, effectively preventing impact and jamming.
[0026] On the side of the elongated top of the connecting piece body 1, there is a boss 6. This boss 6 extends upward to form a step structure 10. Figure 3-4 As shown, when the connecting piece is inserted into the curtain rod 11 of the splicing track, the boss 6 and the step 10 can tightly abut against the baffle 12 inside the curtain rod and conform to the curvature of the inner wall of the rod, thus achieving initial clamping and positioning.
[0027] At both ends of the upper surface of the connecting piece body 1, there is a boss 2 7. Two screw holes 8 are formed in the projection area below each boss 2 7, for a total of four screw holes 8. The boss 2 7 is inserted into the groove 13 of the splicing track curtain rod 11. During installation, first drill holes in the groove 13 corresponding to the screw holes 8, then use self-tapping screws or machine screws to pass through the drilled holes and screw them into the screw holes 8, thereby firmly fixing the connecting piece body 1 to the end of the splicing track curtain rod 11. When two curtain rods need to be connected, align the ends of the two rods with the two sides of the connecting piece and fix them with screws.
[0028] Finally, by using this connecting piece, multiple two-section spliced track curtain rods 11 can be reliably connected and assembled into a complete curtain rod of the required length.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
