Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a quick-install hanging rod. Background Technology

[0002] As people's living standards continue to improve, the demand for efficient use of living space and convenience is increasing. As an indispensable piece of furniture in the bedroom, the expansion and optimization of bed frame functions has gradually become a focus of attention. In recent years, various multifunctional bed frame designs have emerged on the market. For example, a multifunctional intelligent electric bed with application number CN201721828388.X, by adding hanging rods and other structures to the sides of the bed frame for hanging clothes, storing miscellaneous items, etc., effectively utilizes bedroom space and improves the tidiness and practicality of the bedroom. However, existing hanging rod installation methods still have many problems.

[0003] Currently, common methods for installing hanging rods mainly include mounting via mounting slots, threaded connections, and welding. While mounting via mounting slots is relatively simple, the size and structure limitations of the mounting slots can lead to loosening and wobbling during use, resulting in insufficient installation stability and affecting the user experience. Threaded connections, while providing some connection strength, require pre-drilled threaded holes or embedded nuts in the bed frame structure, increasing manufacturing complexity and potentially raising costs. Furthermore, threaded connections require manual tightening of screws, which is cumbersome and prone to affecting installation quality due to improper operation. While welding provides a strong connection, its biggest drawback is the lack of disassembly, making packaging, transportation, and subsequent maintenance and replacement extremely inconvenient, increasing both transportation and operating costs. Utility Model Content

[0004] This utility model provides a quick-installation hanging rod to solve the problem of inconvenient installation of hanging rods in the prior art.

[0005] To achieve the above objectives, the present utility model adopts the following technical solution: a quick-installation hanging rod, which is installed by cooperating with the support square tube through a hanging hole opened on the support square tube, and is used to hang items. The quick-installation hanging rod includes a connecting rod and two limiting rods, and the two limiting rods are symmetrically arranged at both ends of the connecting rod.

[0006] The limiting rod includes a through part, a locking part, a limiting part, and a supporting part. The through part passes through the hanging hole and enters the interior of the supporting square tube. The locking part is formed by bending upward and extending the end of the through part that is used to enter the supporting square tube, and an arc-shaped transition section is formed between the through part and the locking part. The limiting part is formed by bending downward and extending the end of the through part that is not used to enter the supporting square tube. The supporting part is formed by bending and extending the end of the limiting part that is away from the through part. The supporting part is connected to the connecting rod, and the connecting rod is used to hang items.

[0007] The length of the engaging part is less than the width of the supporting square tube in the insertion direction of the through part. The inner radius of the arc transition section is greater than or equal to the wall thickness of the supporting square tube. The axis of the engaging part and the axis of the through part are on the same plane. When the quick-installation hanging rod is installed in conjunction with the supporting square tube, the end of the engaging part away from the through part abuts against the inner wall of the supporting square tube, and the end of the limiting part away from the through part abuts against the outer wall of the supporting square tube. The distance between the projections of the engaging part and the limiting part on the horizontal plane is equal to the thickness of the wall of the supporting square tube.

[0008] Furthermore, the diameter of the hanging hole is greater than or equal to the diameter of the arc-shaped transition section × (1 + safety margin).

[0009] Furthermore, the axis of the support and the axis of the connecting rod are located in the same horizontal plane, and both the support and the connecting rod can be used to suspend items.

[0010] Furthermore, the angle between the axis of the engaging part and the axis of the passing part is 60°-80°.

[0011] Furthermore, the hanging hole extends longitudinally to form a vertical groove, and the width of the vertical groove is greater than the maximum outer diameter of the limiting rod.

[0012] Furthermore, the two limiting rods are respectively installed in two hanging holes on the same horizontal plane.

[0013] The beneficial effects of this utility model are as follows:

[0014] The quick-installation hanging rod provided by this utility model can be quickly installed on the supporting square tube of the bed frame and is easy to disassemble, enabling tool-free installation and providing convenience for users. Attached Figure Description

[0022] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0023] like Figure 1-5 As shown, this utility model embodiment provides a quick-install hanging rod, which is installed by cooperating with the support square tube 1 through the hanging hole 11 opened on the support square tube 1 for hanging items. It includes a connecting rod 3 and two limiting rods 2, with the two limiting rods 2 symmetrically arranged at both ends of the connecting rod 3.

[0024] The limiting rod 2 includes a through-hole 21, a locking part 22, a limiting part 23, and a support part 24. The through-hole 21 passes through the hanging hole 11 and enters the interior of the supporting square tube 1. The locking part 22 is formed by bending upward and extending the end of the through-hole 21 that is used to enter the supporting square tube 1, and an arc-shaped transition section 25 is formed between the through-hole 21 and the locking part 22. The limiting part 23 is formed by bending downward and extending the end of the through-hole 21 that is not used to enter the supporting square tube 1. The support part 24 is formed by bending and extending the end of the limiting part 23 away from the through-hole 21. The support part 24 is connected to the connecting rod 3, and the connecting rod 3 is used to suspend items (when the axis of the support part 24 and the axis of the connecting rod 3 are in the horizontal plane, both the support part 24 and the connecting rod 3 can be used to suspend items).

[0025] The length of the engaging part 22 is less than the width of the supporting square tube 1 in the insertion direction of the through part 21. The inner radius of the arc transition section 25 is greater than or equal to the wall thickness of the supporting square tube 1. Furthermore, to ensure a smoother installation process and avoid installation difficulties due to machining or assembly errors, the diameter of the hanging hole 11 is greater than or equal to the diameter of the arc transition section 25 × (1 + safety margin). The safety margin refers to the extra amount reserved in terms of design dimensions and machining accuracy, taking into account factors such as machining and assembly errors to ensure reliable operation of the product in actual use (in this technical solution, the safety margin value is 0.1-0.2). Figure 3 As shown, Figure 3The dashed lines in the diagram represent the central axes of various parts of the limiting rod 2. The axis of the engaging part 22 and the axis of the through part 21 are on the same plane. When the quick-release hanging rod is installed in conjunction with the supporting square tube 1, the end of the engaging part 22 away from the through part 21 abuts against the inner wall of the supporting square tube 1, and the end of the limiting part 23 away from the through part 21 abuts against the outer wall of the supporting square tube 1. Figure 5 As shown, Figure 5 The dotted circle in the figure refers to the cross section of the limiting part 23 at the contact position between the limiting part 23 and the supporting square tube 1. The distance between the projections of the engaging part 22 and the limiting part 23 on the horizontal plane is the thickness of the wall of the supporting square tube 1. The passing part 21 cannot move in the axial direction of the hanging hole 11 under the restriction of the engaging part 22 and the limiting part 23. The quick-install hanging rod is stably installed on the supporting square tube 1.

[0026] Specifically, during the installation of the quick-installation hanging rod, first insert the engaging part 22 into the hanging hole 11 until the inner arc side of the arc-shaped transition section 25 contacts the hanging hole 11. Then rotate the quick-installation hanging rod so that the arc-shaped transition section 25 enters the supporting square tube 1. After the arc-shaped transition section 25 is completely inside the hanging hole 11, lower the quick-installation hanging rod. Under the action of gravity, the quick-installation hanging rod will rotate until the end of the engaging part 22 away from the through part 21 abuts against the inner wall of the supporting square tube 1. At this time, the end of the limiting part 23 away from the through part 21 abuts against the outer wall of the supporting square tube 1, and the quick-installation hanging rod is installed. The disassembly process of the quick-installation hanging rod is the same. First lift the quick-installation hanging rod and pull it outward so that the inner arc side of the arc-shaped transition section 25 abuts against the hanging hole 11. Then rotate the quick-installation hanging rod so that the arc-shaped transition section 25 comes out of the hanging hole 11. Finally, pull the engaging part 22 out of the hanging hole 11.

[0027] Since the engaging part 22 needs to abut against the inner wall of the supporting square tube 1, it is obvious that if the angle between the axis of the engaging part 22 and the axis of the through part 21 is too large, the engaging part 22 needs to be long enough to abut against the inner wall of the supporting square tube 1. However, if the engaging part 22 is too long, it cannot rotate inside the supporting square tube 1. In addition, if the angle between the axis of the engaging part 22 and the axis of the through part 21 is too small, the engaging part 22 cannot reach the state where the inner arc side of the arc transition section 25 contacts the hanging hole 11 during the process of inserting into the hanging hole 11 (the through part 21 will collide with the supporting square tube 1). Therefore, there is an applicable range for the angle between the axis and the axis of the through part 21. As a preferred embodiment, the angle between the axis of the engaging part 22 and the axis of the through part 21 is 60°-80°.

[0028] To reduce the difficulty of installing the quick-installation rod and to reduce the resistance encountered during the rotation of the curved transition section 25, such as... Figure 4 As shown, in a preferred embodiment of the present invention, the hanging hole 11 extends longitudinally to form a vertical groove 12, and the width of the vertical groove 12 is greater than the maximum outer diameter of the limiting rod 2.

[0029] In order to prevent the hanging rod from tilting after installation and to prevent items from easily falling off the hanging rod, in a preferred embodiment of this utility model, two limiting rods 2 are respectively installed in two hanging holes 11 with their centers on the same horizontal plane.

[0030] In summary, this quick-install hanging rod can be quickly installed on the supporting square tube 1 of the bed frame and is easy to disassemble, enabling tool-free installation and providing convenience for users. Furthermore, the quick-install hanging rod provided by this utility model can not only be used on bed frames, but also on shelves and other items with square hollow supporting tubes.

[0031] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
