Description

Technical Field

[0001] This utility model belongs to the technical field of telescopic drying racks, and in particular relates to a telescopic drying rack with a flip hook. Background Technology

[0002] Currently, telescopic drying racks (also known as telescopic poles or nail-free support poles) are widely used in homes, dormitories, and other places due to their advantages of requiring no drilling and being easy to install. They are used to erect temporary or semi-permanent drying and hanging racks between two fixed surfaces (such as walls or cabinets). These products typically consist of a telescopic pole (such as a thick tube and a thin tube connected together) and support bases at both ends. The pole is fixed by adjusting its length and utilizing the pressure between the bases and the supporting surfaces.

[0003] However, existing telescopic drying racks still have some shortcomings: Poor locking and adjustment convenience: Most products use simple threaded tightening or snap-fit ​​methods to achieve relative locking of the thick and thin tubes. These structures either have limited locking force, making them prone to loosening and slipping during use, or are cumbersome to operate, requiring multiple rotations or the application of considerable force. At the same time, fine-tuning of the rod length usually relies on the coarse positioning of the telescopic part, making it difficult to achieve precise tension after installation. This can easily lead to one end not fitting tightly or poor overall stability due to length mismatch.

[0004] Insufficient reliability of anti-slip fixation: The base's fixation to the wall (especially smooth ceramic, glass, or painted surfaces) relies primarily on the friction of rubber or silicone pads. Under long-term load, changes in environmental humidity, or slight vibrations, this reliance on friction alone can easily cause the rod to slip or detach, posing a safety hazard. Although some products attempt to add patterns or use adhesives, the former offers limited improvement, while the latter may damage the wall and is inconvenient to adjust.

[0005] Limited functionality: Traditional telescopic drying racks primarily offer hanging functionality for the rack itself, lacking additional, convenient storage hanging points. If users need to hang small items (such as towels, rags, tool bags, etc.) near the rack, they often need to install hooks separately, which is not only inconvenient but may also affect the aesthetics or the balance of the rack.

[0006] Storage and aesthetics are not well considered: Some products with additional hooks are mostly fixed and exposed, which still protrude when not in use, making them easy to bump into other objects or snag on clothes, affecting the tidiness and safety of the space, and lacking a hidden storage design.

[0007] Therefore, it is necessary to design a new type of telescopic drying rack that, while ensuring ease of installation, provides a more reliable locking and tensioning mechanism, enhances its anti-slip and fixing effect on various wall surfaces, and integrates a flip-up storage hook to expand its functionality and improve the overall practicality and aesthetics of the product. Utility Model Content

[0008] The purpose of this invention is to provide a telescopic drying rack with a flip hook to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the specific technical solution of this utility model for a telescopic drying rack with a flip hook is as follows: A telescopic drying rack with a flip hook includes a thick tube, a thin tube, an inner locking mechanism, a flip hook assembly, a fine-tuning tensioning mechanism, a first base, and a second base. One end of the thick tube is inserted into the shaft hole of the first base, achieving a rotatable connection with the first base. One end of the thin tube is inserted into the other end of the thick tube, achieving extension and initial locking through the inner locking mechanism. The other end of the thin tube is connected to the second base through the fine-tuning tensioning mechanism, used for fine-tuning the length of the rod, ensuring that the first and second bases are firmly fixed against the wall. The lower inner side of the first and second bases has a flip hook assembly, which can rotate around the first or second base for hanging everyday items.

[0010] Furthermore, the sides of the first and second bases that contact the wall are processed with dense deep patterns and have multiple circular recessed areas evenly distributed in a ring.

[0011] Furthermore, the recessed area has six regions.

[0012] Furthermore, the internal locking mechanism includes a threaded component, a plastic expansion component, and a beveled component. One end of the threaded component is a circular fixed end, the middle is a threaded portion, and the other end is a beveled fixed end. The circular fixed end is used to embed into the end face of the thin tube and is fixedly connected to the thin tube. The plastic expansion component is sleeved outside the threaded portion and is threadedly connected to the threaded portion. The beveled component is fixed to the beveled fixed end of the threaded component by fasteners.

[0013] Furthermore, the fastener is a screw or a snap fastener.

[0014] Furthermore, the threaded portion one and the inclined plate extend into the interior of the thick tube. The diameter of the threaded portion one is the same. The inclined plate gradually increases in size from the connection point of the threaded portion one to the distal end. The maximum diameter of the inclined plate is smaller than the inner diameter of the thick tube. One end of the plastic expansion member has a threaded portion two, which is threadedly connected to the threaded portion one. The other end has multiple equally spaced strip-shaped teeth. The gaps between the strip-shaped teeth provide expansion space for the plastic expansion member. The inner side of the distal end of the strip-shaped teeth has an inclined surface that can cooperate with the inclined plate.

[0015] Furthermore, the fine-tuning tensioning mechanism includes a connecting seat and a tensioning screw. One end of the connecting seat is rotatably connected to the second base, and the bottom inner side of the connecting seat has an internal thread. One end of the tensioning screw is fixedly connected to the end of the thin tube, and the other end has an external thread. The tensioning screw and the thin tube are fitted into the connecting seat together, and the external thread of the tensioning screw can engage with the internal thread of the connecting seat.

[0016] Furthermore, the first base and the second base have a pin connecting seat on their inner sides. The pin connecting seat is used to connect the pin. The flip hook assembly includes a rotating part and a hook part. The rotating part is rotatably connected to the pin connecting seat through the pin. The hook part can flip around the pin.

[0017] Furthermore, the pin connector has raised ribs to increase friction with the hook portion.

[0018] The telescopic drying rack with a flip hook of this utility model has the following advantages: 1. Dual-level locking and adjustment ensures secure and convenient installation: Internal locking mechanism: The relative rotation of the thick and thin tubes drives the plastic expansion component to move axially and expand radially on the inclined surface, thereby generating a strong radial friction force to lock the rod. This mechanical self-locking method has a large and reliable locking force, is simple to operate (only rotation is required), and effectively prevents the rod from accidentally shrinking or loosening during use.

[0019] Fine-tuning tensioning mechanism: After initial locking, the rod length can be precisely adjusted down to the micrometer level by rotating the connecting seat and utilizing the screw thread pair. This ensures that the first and second bases are tightly pressed against the wall during installation, eliminating any play and ensuring optimal overall tension, significantly improving overall stability after installation.

[0020] 2. Composite anti-slip fixing, highly adaptable and safe and reliable: The contact surface between the base and the wall utilizes a combination of a dense, deep pattern and a circular array of recessed areas. The deep pattern provides basic static friction. When the base is pressed against the wall, the air inside the multiple recessed areas is expelled, creating localized negative pressure and generating a suction cup-like adsorption effect. The synergistic effect of friction and adsorption significantly enhances the base's ability to stay firmly on smooth surfaces (such as tiles, glass, and painted surfaces), significantly improving its anti-slip and anti-pull-down capabilities, and increasing safety.

[0021] 3. Integrated with a retractable flip hook, expanding functionality while maintaining a neat and aesthetically pleasing appearance: The first and second bases integrate hook assemblies that can rotate around an axis. When small items (such as towels, rags, keys, etc.) need to be hung, the hooks can be flipped down for use, greatly expanding the practicality of the drying rack.

[0022] When not in use, the hooks can be flipped upwards and completely stored inside the base. This concealed design avoids problems such as bumps and snagging on clothes that might be caused by exposed hooks, maintaining the cleanliness and aesthetics of the space and reflecting a user-friendly design.

[0023] 4. Compact structure, intuitive operation, and excellent user experience: The entire device integrates multiple functions such as telescopic, locking, fine-tuning, anti-slip, and hooking into a simple structure. The logic of each component is clear, and the operation steps are intuitive (twist, pull, turn). Users can complete the installation, adjustment, and function switching without the need for tools, greatly improving the convenience and user experience.

[0024] In summary, this utility model not only solves the inherent defects of traditional telescopic drying racks, but also achieves functional integration and performance optimization through ingenious mechanism design, possessing comprehensive advantages such as stability and reliability, convenient installation, diverse functions, and aesthetic appeal.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a telescopic drying rack with a flip hook.

[0028] like Figures 1 to 4 As shown, the present invention provides a telescopic drying rack with a flip hook, comprising a thick tube 1, a thin tube 2, an inner locking mechanism 3, a flip hook assembly 4, a fine-tuning tensioning mechanism 5, a first base 6, and a second base 7.

[0029] One end of the thick tube 1 is inserted into the shaft hole of the first base 6, and is rotatably connected to the first base 6, so that the end of the thick tube 1 can rotate freely during the installation process.

[0030] One end of the thin tube 2 is inserted into the other end of the thick tube 1, and extension and initial locking are achieved through the inner locking mechanism 3. The other end of the thin tube 2 is connected to the second base 7 through the fine-tuning tensioning mechanism 5, which is used to fine-tune the length of the rod and to ensure that the first base 6 and the second base 7 are tightly fixed to the wall.

[0031] The surfaces of the first base 6 and the second base 7 that contact the wall are processed with dense, deep patterns 71, and six circular recessed areas 72 are evenly distributed in a ring. During installation, the first base 6 and the second base 7 are pressed tightly against the wall, and the air in the recessed areas 72 is expelled, creating a local negative pressure that generates a suction cup effect. This, combined with the friction of the deep patterns 72, achieves strong anti-slip properties.

[0032] As shown in the figure, the inner locking mechanism 3 includes a threaded component 31, a plastic expansion component 32, and a beveled component 33. One end of the threaded component 31 is a circular fixed end 311, the middle is a threaded portion 312, and the other end is a beveled fixed end 313. The circular fixed end 311 is used to embed into the end face of the thin tube 2 and is fixedly connected to the thin tube 2. The plastic expansion component 32 is sleeved on the threaded portion 312 and is threadedly connected to the threaded portion 312. The beveled component 33 is fixed to the beveled fixed end 313 of the threaded component 31 by a fastener 34. Preferably, the fastener 34 is a screw or a snap fastener.

[0033] The threaded portion 312 and the beveled member 33 extend into the interior of the thick tube 1. The threaded portion 312 has a uniform diameter, and the beveled member 33 gradually increases in size from the connection point of the threaded portion 312 to the distal end (the end away from the threaded portion 312). The maximum diameter of the beveled member 33 is smaller than the inner diameter of the thick tube 1, and it can slide axially along the interior of the thick tube 1 when not locked. One end of the plastic expansion member 32 has a threaded portion 321, which is threadedly connected to the threaded portion 312. The other end has a plurality of equally spaced strip-shaped teeth 322, and the gaps between the strip-shaped teeth 322 provide expansion space for the plastic expansion member 32. The inner side of the distal end of the strip-shaped teeth 322 (the end away from the threaded portion 321) has a beveled surface 3221, which can mate with the beveled member 33. Under the action of friction, the plastic expansion member 32 and the inner wall of the thick tube 1 can rotate with the thick tube 1. When the thick tube 1 and the thin tube 2 rotate relative to each other, the plastic expansion member 32 moves axially relative to the threaded member 31 under the action of the thread. When the strip teeth 322 of the plastic expansion member 32 move to the inclined surface 33, under the action of the inclined surface, the strip teeth 322 expand outward, the inner diameter increases, and it contacts the inner wall of the thick tube 1, forming frictional resistance, thereby locking the thin tube 2 and the thick tube 1, preventing them from expanding or contracting relative to each other. Similarly, when rotating in the opposite direction, the thin tube 2 and the thick tube 1 unlock, allowing them to expand or contract relative to each other.

[0034] like Figure 2 As shown, the fine-tuning tensioning mechanism 5 includes a connecting seat 51 and a tensioning screw 52. One end of the connecting seat 51 is rotatably connected to the second base 7. The bottom inner side of the connecting seat 51 has an internal thread 511. One end of the tensioning screw 52 is fixedly connected to the end of the thin tube 2, and the other end has an external thread 521. The tensioning screw 52 and the thin tube 2 are fitted into the connecting seat 51 together. The external thread 521 of the tensioning screw 52 can engage with the internal thread 511 of the connecting seat 51. When the thin tube 2 is fitted into the connecting seat 51, it is rotated first to pre-connect the external thread 521 of the tensioning screw 52 with the internal thread 511 of the connecting seat 51. During adjustment, the thin tube 2 is held still, and the connecting seat 51 is rotated to make the connecting seat 51 move axially relative to the tensioning screw 52, ​​thereby adjusting the distance between the thin tube 2 and the second base 7 to achieve the tensioning effect, so that the first base 6 and the second base 7 are fixed tightly against the wall.

[0035] The lower inner sides of the first base 6 and the second base 7 have flip-up hook assemblies 4 for hanging everyday items. Specifically, the inner sides of the first base 6 and the second base 7 have pin connecting seats 61 for connecting pins. The flip-up hook assembly 4 includes a rotating part 41 and a hook part 42. The rotating part 41 is rotatably connected to the pin connecting seat 61 via a pin. The hook part 42 can be flipped around the pin. Flipping it upwards allows the hook part 42 to be stored inside the first base 6 or the second base 7 without obstructing other objects. The pin connecting seat 61 has protruding ribs 611, which increase the friction with the hook part 42 when it is stored, ensuring a secure fixation and preventing the hook part 42 from coming off. When the hook is needed, the hook part 42 can be flipped downwards to a vertical position, increasing the functionality of the drying rack.

[0036] The operating steps are as follows: Step 1: Loosen the inner locking mechanism 3, stretch the thin tube 2, adjust the rod to a length slightly shorter than the actual distance between the two walls, place the rod horizontally into the installation position, align the first base 6 and the second base 7 with the wall, and then rotate the thin tube 2 or the thick tube 1 to gradually lock the inner locking mechanism 3.

[0037] Step 2: Hold the end of the thin tube 2 and rotate the connecting seat 51 to make the connecting seat 51 move axially relative to the tensioning screw 52, ​​thereby adjusting the distance between the thin tube 2 and the second base 7 to achieve tension, so that the first base 6 and the second base 7 are in close contact with the wall. The deep pattern 71 on the surface of the base and the six ring array of recessed areas 72 work together to provide strong static friction and adsorption force.

[0038] Step 3: As needed, flip the flip hook assembly 4 installed on the first base 6 and the second base 7 to unfold the hook part 42 for use, or fold it for storage.
