Description

Technical Field

[0001] This utility model relates to the field of clothes drying rack technology, and more specifically, to a telescopic drying rod guide sleeve installation structure and a telescopic drying rod assembly for clothes drying racks. Background Technology

[0002] Telescopic drying rods are a common type of drying rod among existing clothes racks. They are usually equipped with telescopic rods at both ends of the main body of the drying rod. When the telescopic rod is extended, it can expand the drying space, increase the amount of clothes that can be dried, and dry large items such as quilts. When the telescopic rod is retracted, it can reduce the space occupied by the drying rod and make it convenient to store.

[0003] To ensure the stability of the telescopic drying rod's telescopic movement within the main body, a guide sleeve is installed at the end of the main body. The telescopic drying rod and the guide sleeve work together to improve the stability of its telescopic movement. The guide sleeve is usually an injection-molded part. The connection between the main body and the guide sleeve mainly adopts a snap-fit ​​structure, that is, snap holes are opened at both ends of the main body, and a protrusion is integrally formed on the outer wall of the guide sleeve. When the guide sleeve is inserted into the end of the main body, the connection between the two is achieved by the engagement of the protrusion and the snap holes. For example, the "A Telescopic Rod Assembly and Clothes Drying Rack" published with publication number CN222185341U and publication date December 17, 2024, etc. Since the drying rod mainly bears the weight of the clothes during the drying process, it is required that the drying rod has strong bending strength. Therefore, while meeting the hanging size of the clothes and effectively controlling the manufacturing cost, the cross-sectional dimensions of the telescopic drying rod need to be as large as possible. In other words, while keeping the cross-sectional dimensions of the main body of the drying rack constant, the cross-sectional dimensions of the telescopic drying rack need to be as large as possible. This results in a smaller wall thickness for the guide sleeve located between the main body and the telescopic drying rack. Combined with the design requirements such as the demolding angle needed for the injection molding of the guide sleeve, this leads to a weaker interlocking force between the protrusion and the clamping hole of the main body, resulting in poor installation stability of the guide sleeve on the main body. In actual use, it has been found that because the protrusion is made of relatively soft plastic, it is easily damaged by shearing forces within the clamping hole of the main body, leading to a weak connection between the guide sleeve and the main body. Consequently, the guide sleeve can easily detach from the end of the main body, causing the telescopic drying rack to disintegrate and break. Currently, the common remedy is to fill the gap between the guide sleeve and the main body with glue to improve the connection strength. However, this method is effective in the short term, but with long-term use, there is a risk of the guide sleeve loosening. Summary of the Invention

[0037] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0038] [Example]

[0039] Combination Figures 1 to 7 As shown, this embodiment of a telescopic drying rod guide sleeve installation structure includes a drying rod body 1 and a guide sleeve 2 fitted onto the end of the drying rod body 1. The drying rod body 1 is made of metal tubing or profile tubing, and the guide sleeve 2 is manufactured using injection molding. The guide sleeve 2 has a guide hole 2-1, the size of which is adapted to the size of the telescopic drying rod 3, allowing the telescopic drying rod 3 to extend and retract within the guide hole 2-1. In this embodiment, the end of the drying rod body 1 has several circumferential cuts 1-1. The side of the cuts 1-1 closest to the end of the drying rod body 1 is pressed inward to form a concave oblique buckle 1-2. The outer wall of the guide sleeve 2 has a groove 2-2 that can engage with the aforementioned concave oblique buckle 1-2. Due to the design of the notch 1-1, during the extrusion process, the tube wall at the notch 1-1 is concave inward, forming a snap-fit ​​structure protruding from the inner wall of the drying rod body 1. The other side of the concave angled snap-fit ​​1-2 is connected to the tube wall, forming a slope structure with a certain angle, which facilitates the assembly of the guide sleeve 2 and the drying rod body 1. During assembly, the guide sleeve 2 is guided into the end of the drying rod body 1 along the slope of the concave angled snap-fit ​​1-2. After the guide sleeve 2 is installed in place, the concave angled snap-fit ​​1-2 is engaged with the slot 2-2. Compared with the existing design, the protrusion on the outer wall of the guide sleeve is smaller, so its structural strength is poor. When it is engaged with the snap-fit ​​hole on the drying rod body, it is prone to loosening due to shearing damage. The telescopic drying rod guide sleeve installation structure of this embodiment has a buckle structure formed on the drying rod body 1, which has better strength. A groove 2-2 is set on the guide sleeve 2. The groove 2-2 and the concave angled buckle 1-2 are more firmly connected, which greatly improves the connection between the guide sleeve 2 and the drying rod body 1, reduces the probability of the guide sleeve 2 loosening, and improves the service life of the telescopic drying rod. In addition, the concave angled buckle 1-2 is extruded by cutting 1-1, which has a simple structure, is easy to process and manufacture, and the connection between the concave angled buckle 1-2 and the guide sleeve 2 is stable and reliable.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the side of the concave angled buckle 1-2 away from the root forms a cut surface 1-2a, and the locking surface 2-2a of the groove 2-2 that abuts against the cut surface 1-2a of the concave angled buckle 1-2 is a plane. After the guide sleeve 2 is installed into the end of the drying rod body 1, the cut surface 1-2a of the concave angled buckle 1-2 and the locking surface 2-2a of the groove 2-2 form an anti-reverse engagement structure. The fit between the cut surface 1-2a of the concave angled buckle 1-2 and the locking surface 2-2a of the groove 2-2 enables a unidirectional and secure engagement, effectively restricting the axial movement of the guide sleeve 2. The inner angled surface of the concave angled buckle 1-2 also guides the installation of the guide sleeve 2, allowing the guide sleeve 2 to be smoothly inserted into the end of the drying rod body 1 and securely connected, making assembly simple and convenient.

[0041] In this embodiment, the aforementioned concave angled buckle 1-2 is preferably formed by stamping inward from the outer side wall of the drying rod body 1, which is simple, efficient, and low-cost to manufacture. The aforementioned groove 2-2 is a continuous annular groove or an intermittent groove provided on the outer side wall of the guide sleeve 2. Since the outer side of the groove 2-2 has more material and a thicker wall, it is not easily damaged by the shearing action of the concave angled buckle 1-2. The continuous annular groove design eliminates the need to align the groove when installing the guide sleeve 2, making manufacturing convenient and assembly simpler. The intermittent groove design can prevent the guide sleeve 2 from rotating, resulting in better connection stability. Figure 3 and Figure 7 The guide sleeve 2 shown has a continuous annular groove design for its groove 2-2, which is simple and convenient to manufacture. For example... Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment, one end of the guide sleeve 2 is also provided with a limiting platform 2-3 for cooperating with the end face of the drying rod body 1. The outer circumferential dimensions of the limiting platform 2-3 are adapted to the outer contour dimensions of the drying rod body 1, which can limit the installation of the guide sleeve 2 and at the same time block the sharp end face of the drying rod body 1, improving the safety of the drying rod. As an optional implementation, a number of weakening holes 2-4 extending along the length direction of the guide sleeve 2 are also provided on the side wall of the guide sleeve 2. The weakening holes 2-4 make the side wall of the guide sleeve 2 have better elastic deformation performance, making the guide sleeve 2 easier and less strenuous to install; the end of the guide sleeve 2 away from the limiting platform 2-3 can also be provided with a chamfer 2-5, further facilitating the assembly of the guide sleeve 2.

[0042] This embodiment also relates to a telescopic clothes drying rod assembly. (See reference...) Figures 1 to 4As shown, the telescopic clothes drying rod assembly includes a main body 1 and telescopic drying rods 3 located at both ends of the main body 1. Both ends of the main body 1 are equipped with guide sleeves 2 using the aforementioned telescopic drying rod guide sleeve mounting structure. The telescopic drying rods 3 slide and guide with the guide holes 2-1 of the corresponding guide sleeves 2. The guide sleeves 2 of this telescopic drying rod assembly are securely installed, providing more stable and reliable guidance for the telescopic drying rods 3, thus improving the stability and service life of the telescopic clothes drying rod assembly.

[0043] like Figure 3 and Figure 4 As shown, in this embodiment, the end of the telescopic drying rod 3 located inside the main body 1 also has an anti-detachment structure, which can limit the extension length of the telescopic drying rod 3 and prevent the telescopic drying rod 3 from being completely pulled out and separating from the main body 1. The aforementioned anti-detachment structure can be a plug or other structure fixed to the end of the telescopic drying rod 3, with a size larger than the guide hole 2-1 of the guide sleeve 2. Therefore, when the telescopic drying rod 3 is pulled out to its maximum length, it can form a stop. Specifically, in this embodiment, the aforementioned anti-detachment structure is an anti-detachment rib 3-1 formed on one end of the telescopic drying rod 3. The anti-detachment rib 3-1 can be integrally formed on the tube wall of the telescopic drying rod 3 by an extrusion process, which is simple in structure and easy to manufacture.

[0044] In this embodiment, the cross-sectional shape of the main body 1 and the telescopic drying rod 3 can be a common drying rod cross-sectional shape such as a circle, square, or trapezoid, or other irregular cross-sectional shapes, depending on the design of the clothes rack. The telescopic drying rod assembly is installed on the lifting mechanism of the clothes rack. The lifting mechanism can be an electric motor or a hand-cranked lifting device. The telescopic drying rod assembly can be used as a clothes drying rod or a quilt drying rod.

[0045] This utility model discloses a guide sleeve installation structure for a telescopic clothes drying rod and a telescopic clothes drying rod assembly. By setting several circumferential slits at the end of the main body of the drying rod, and forming a concave oblique buckle by pressing inward on the side of the slits near the end of the main body, the concave oblique buckle engages with a groove on the outer wall of the guide sleeve, greatly improving the connection between the guide sleeve and the main body of the drying rod, reducing the probability of the guide sleeve loosening, and extending the service life of the telescopic clothes drying rod. Furthermore, the concave oblique buckle, formed by pressing the slits, has a simple structure, is easy to manufacture, and provides a stable and reliable connection between the concave oblique buckle and the guide sleeve. The guide sleeve of the telescopic clothes drying rod assembly is firmly installed, providing more stable and reliable guidance for the telescopic clothes drying rod, thus improving the stability and service life of the telescopic clothes drying rod assembly.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
