Description

Technical Field

[0001] This application relates to the field of storage rack technology, specifically to a telescopic towel rack. Background Technology

[0002] Towel racks are common bathroom fixtures used for hanging towels, bath towels, and other toiletries. They typically have mounting brackets at both ends and at least one hanging rod in the middle, connecting to the wall via the brackets. Most towel racks on the market are not adjustable in size after installation. To meet market demand, some telescopic towel racks have emerged, but these are mostly width-adjustable, which can cause inconvenience when the width increases. Although length-adjustable towel racks have also appeared, such as the technical solution disclosed in CN209074400U, they still have many shortcomings.

[0003] 1. Extension rod is prone to deformation under stress: This solution uses a one-sided extension method. In order to increase the effective usable length, the length of the extension rod body will be as long as possible. When the extension rod body is too long, it is prone to deformation under stress, which affects the normal use and aesthetics of the towel rack.

[0004] 2. The extension rod manufacturing process is complex: the anti-detachment block and the extension rod body are manufactured independently, and after completion, they need to be assembled using corresponding installation methods. This not only increases the complexity of the manufacturing process, but also makes the extension rod body prone to deformation due to uneven stress during assembly, thus affecting product quality.

[0005] 3. Inconvenient replacement of the mounting base: The mounting base is a one-piece structure. Once it is installed on the wall, if it needs to be replaced, the entire mounting base must be completely removed, which is a cumbersome operation and causes inconvenience to users. Utility Model Content

[0006] In view of this, this application provides a telescopic towel rack to solve the technical problems of low structural stability and difficulty in replacement of existing telescopic towel racks.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A telescopic towel rack includes two mounting bases and a hanging rod assembly. The hanging rod assembly includes a hollow fixed hanging rod and two extension hanging rods. The ends of the fixed hanging rods are connected by inserting into stepped holes provided on the corresponding mounting bases. The extension hanging rods are slidably installed in the fixed hanging rods and extend out along the corresponding mounting bases. The extension hanging rods include extension hanging rod bodies with a two-stage stepped shaft structure. A shoulder surface is formed at the diameter change of the extension hanging rod body. The large-diameter end of the extension hanging rod body is slidably engaged with the inner hole of the fixed hanging rod, and the small-diameter end of the extension hanging rod body is slidably engaged with the small-diameter hole of the stepped hole. The shoulder surface and the stepped surface of the stepped hole abut against each other to achieve a blocking function.

[0009] Furthermore, the outer end of the extended hanging rod has an end limiter.

[0010] Furthermore, the end limiting member is a ball head that is threadedly connected to the extension hanging rod body of the extension hanging rod.

[0011] Furthermore, the mounting base includes a separable, assembled mounting base and a connecting base, with a stepped hole located on the connecting base.

[0012] Furthermore, the connecting seat has a cover that fits into the fixed seat, and the side wall of the cover has a through screw hole, and the screw installed in the screw hole presses against the side of the fixed seat.

[0013] Furthermore, the inner wall of the cover is provided with a limiting protrusion, and the circumferential surface of the fixing seat is provided with a limiting notch that cooperates with the limiting protrusion.

[0014] Furthermore, the center-facing side of the limiting protrusion is provided with a snap-fit ​​inclined surface that abuts against the fixing seat, and the snap-fit ​​inclined surface causes the thickness of the limiting protrusion to gradually decrease from the outside to the inside.

[0015] Furthermore, the inner wall of the casing is provided with reinforcing ribs corresponding to the positions of the screw holes.

[0016] As can be seen from the above technical solution, the advantages of this utility model are:

[0017] 1. High strength of the extension hanging rod: The extension hanging rod is an integral structure with two ends. Compared with the existing technology where the anti-slip block and the extension rod body are made and combined separately, it is stronger and the shortened length can effectively avoid the problem of deformation due to stress, thus extending the service life of the towel rack.

[0018] 2. Easy replacement of mounting base: Mounting base 1 adopts a modular structure. When replacement is required, only the connecting base needs to be disassembled. There is no need to repeatedly disassemble the fixing base, which greatly simplifies the replacement process, improves replacement efficiency, and ensures the stability of installation.

[0019] 3. Simple structure and easy assembly: The connection methods of each component in this solution are simple and reasonable, such as the plug-in fit between the fixed rod and the mounting base, the sliding installation of the telescopic rod and the fixed rod, and the combination method of each component of the mounting base. This not only facilitates production and assembly, but also reduces manufacturing costs and improves production efficiency.

[0020] 4. Reliable positioning and fixing: The stability and reliability of the connection between the various parts of the towel rack are ensured by the abutment between the convex shoulder surface and the stepped surface of the stepped hole, the cooperation between the limiting card protrusion and the limiting notch groove, and the pressing and fixing of the screws, preventing loosening or falling off during use.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0031] refer to Figures 1 to 7 ,like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, this embodiment provides a telescopic towel rack, including two mounting bases 1 and at least one hanging rod assembly. The hanging rod assembly includes a hollow fixed hanging rod 2 and two extension hanging rods 3. The ends of the fixed hanging rods 2 are connected by inserting into stepped holes 121 provided on the corresponding mounting bases 1. The connection method is simple and reliable, and easy to install and disassemble. The extension hanging rods 3 are slidably installed in the fixed hanging rods 2 and extend out along the corresponding mounting bases 1. The extension hanging rods 3 include extension hanging rod bodies 31 with a two-stage stepped shaft structure. The diameter change of the extension hanging rod body 31 forms a shoulder surface 311. The large diameter end of the extension hanging rod body 31 is slidably engaged with the inner hole of the fixed hanging rod 2. The small-diameter end of the rod 31 slides into the small-diameter hole of the stepped hole 121. The shoulder surface 311 abuts against the stepped surface of the stepped hole 121 to achieve a blocking function, effectively preventing the telescopic rod 3 from sliding out of the fixed rod 2 and the mounting base 1, ensuring the stability of the towel rack. The extended hanging rod 31 is designed to maximize the diameter of the small-diameter end of the extended hanging rod 31 while meeting the requirement of generating the shoulder surface 311, thereby increasing its strength. The extended hanging rod 31 adopts an integrated structure, which makes installation convenient and provides high structural strength. The structure of two extended hanging rods 3 meets the effective length requirement while reducing the cantilever length of the extended hanging rod 3, making it less prone to deformation under stress.

[0032] In order to prevent the towel from slipping off the end of the extension hanging rod 3, and also to prevent the extension hanging rod 3 from retracting too much and affecting subsequent use, the outer end of the extension hanging rod 3 has an end limit member 32.

[0033] Preferably, in this application, the end limiting member 32 is a ball head that is threadedly connected to the extension hanging rod body 31 of the extension hanging rod 3. The ball head not only serves as a limiting element but also enhances the aesthetics of the towel rack, while the threaded connection facilitates installation and disassembly.

[0034] To facilitate the replacement of the components of the telescopic towel rack, the mounting base 1 includes a detachable, assembled fixed base 11 and a connecting base 12. The fixed base 11 has multiple mounting holes for bolts to pass through and connect to the wall, and a stepped hole 121 is located on the connecting base 12. This modular structure allows only the connecting base 12 to be disassembled when the mounting base needs to be replaced, avoiding repeated disassembly of the fixed base 11, thus ensuring stable installation and convenient replacement.

[0035] In actual use, the connection between the fixed seat 11 and the connecting seat 12 can be either a flexible snap-fit ​​or a screw-through connection. The flexible snap-fit ​​is easy to loosen after long-term use, causing the flexible snap-fit ​​to automatically separate from the fixed seat 11. The screw-through connection requires at least two screws, which makes disassembly and assembly somewhat inconvenient.

[0036] In this embodiment, preferably, such as Figure 5As shown, the connecting seat 12 has a cover 122 that fits into the fixed seat 11. The fixed seat 11 is in the shape of a hollow boss. The side wall of the cover 122 is provided with a through screw hole 126. The screw installed in the screw hole 126 presses against the side of the fixed seat 11. The screw's thrust is used to lock the cover 122 against the fixed seat 11. The connecting seat 12 also has a convex shaft portion connected to the cover 122. A stepped hole 121 is radially provided on the convex shaft portion.

[0037] In this application, a limiting protrusion 123 is provided on the inner side wall of the cover 122, and a limiting notch 111 that mates with the limiting protrusion 123 is provided on the circumferential surface of the fixing seat 11. This limiting structure can ensure the accuracy and stability of the connecting seat 12 and the fixing seat 11 during assembly. By limiting the connecting seat 12, it prevents the torque generated by the rotation of the connecting seat 12 on the fixed hanging rod 2 during installation from affecting the load-bearing capacity of the fixed hanging rod 2 and the extension flexibility of the extension hanging rod 3.

[0038] To ensure a more reliable connection between the cover 122 and the fixing seat 11, a snap-fit ​​inclined surface 124 is provided on the center-facing side of the limiting protrusion 123 to abut against the fixing seat 11. The snap-fit ​​inclined surface 124 causes the thickness of the limiting protrusion 123 to gradually decrease from the outside to the inside. Utilizing the guiding effect of the snap-fit ​​inclined surface 124 during assembly, when the screws are tightened, the cover 122 will move closer to the fixing seat 11 until the end face of the cover 122 abuts against the end face of the fixing seat 11, improving the stability of the connecting seat 12 in use. Furthermore, the connecting seat 12 can prevent the fixing seat 11 from sliding outwards, ensuring a reliable and stable connection between the connecting seat 12 and the fixing seat 11.

[0039] In order to improve the structural strength at the screw hole 126 and improve the connection stability between the connecting seat 12 and the fixed seat 11, the inner side wall of the cover 122 is provided with a reinforcing rib 125 corresponding to the position of the screw hole 126, and the screw hole 126 passes through the reinforcing rib 125.

[0040] When it is necessary to replace the fixed hanging rod 2, the connecting seat 12, or the extension hanging rod 3, the connecting seat 12 can be loosened and removed by unscrewing the screw installed in the screw hole 126, and then the corresponding part can be replaced. The fixed seat 11 does not need to be disassembled during the whole process, which makes the operation convenient and does not affect the installation stability of the fixed seat 11.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
