Description

Technical Field

[0001] This utility model relates to a clothes drying rack, and more specifically, to a reinforced drying rod and clothes drying rack. Background Technology

[0002] Clothes drying racks are typically installed on the ceiling of balconies and usually consist of a main unit that controls the lifting and lowering of the rack, and a drying rod connected to the bottom of the main unit. The drying rod is the main load-bearing component, and it is usually suspended from both ends. To improve the strength of the drying rod, most clothes drying racks on the market use an inverted "T" shaped cross-section, that is, a vertical hanging plate is set on the upper side of the main body of the drying rod to improve its bending resistance. However, this inverted "T" shaped cross-section drying rod has a larger height dimension, and requires more vertical space for storage.

[0003] Currently, there is also a type of drying rack using sliding clothes hangers. The main body of this rack is roughly rectangular, with a groove at the top containing several clothes hangers arranged in spaced-out hanging slots. Because the vertical hanging board is eliminated, the rack's dimensions need to be increased to ensure its load-bearing capacity and bending resistance. However, due to the size of the clothes hanger hooks, the cross-sectional dimensions of the rack cannot be too large; generally, the width and height of the rack do not exceed 30mm. Therefore, the load-bearing capacity and bending resistance of this structure are relatively limited, especially in longer racks where the downward bending in the middle is more pronounced.

[0004] Given the aforementioned problems with existing drying rack structures, it is necessary to design a reinforced drying rack with higher structural strength and stronger load-bearing capacity. Summary of the Invention

[0005] 1. Technical problem to be solved by the utility model

[0006] The purpose of this invention is to overcome the shortcomings of existing clothes drying rods in terms of poor load-bearing capacity and bending resistance, and to provide a reinforced clothes drying rod and rack. The technical solution of this invention utilizes an outer rod and an inner rod to form a double-layered reinforced structure, which greatly improves the structural strength of the drying rod and its load-bearing and bending resistance without increasing the cross-sectional dimensions of the drying rod. This solves the problem of long drying rods suspended at both ends being prone to bending and deformation. Furthermore, due to the increased strength of the drying rod, it can be used for drying rods without vertical hanging boards, which helps to reduce the overall height of the drying rod and makes the structure of the entire clothes drying rack more compact.

[0025] 3. Beneficial effects

[0026] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0027] (1) A reinforced clothes drying rack of this utility model includes an outer rod body, an inner rod body and end caps. The outer rod body is made of hollow profile rod, and the inner rod body is inserted through the rod cavity of the outer rod body to form a double-layer reinforced structure. The end caps are respectively located at both ends of the outer rod body. By combining the outer rod body and the inner rod body to form a double-layer reinforced structure, the structural strength of the clothes drying rack is greatly improved without increasing the cross-sectional size of the clothes drying rack. This improves the load-bearing and bending resistance of the clothes drying rack and solves the problem of easy bending and deformation of long clothes drying racks suspended at both ends. Furthermore, due to the increased strength of the clothes drying rack, it can be used for clothes drying racks without vertical hanging boards, which is conducive to reducing the overall height of the clothes drying rack and making the structure of the entire clothes drying rack more compact.

[0028] (2) The present invention provides a reinforced drying rack, wherein the outer rod body is provided with a hanging groove structure for hanging clothes, which facilitates the hanging of clothes; furthermore, the upper side of the outer rod body is provided with a sliding groove extending along the length direction, and the sliding groove is provided with a number of hanging groove sliders, which form a hanging groove with intervals. The structure is simple and easy to manufacture, and the number of hanging grooves can be flexibly adjusted as needed. Moreover, the height of the hanging groove sliders is small, which further reduces the overall height of the drying rack; the sliding groove structure can further improve the bending strength of the outer rod body.

[0029] (3) The present invention provides a reinforced drying rack with a height distance h between the bottom of the hanging groove and the bottom surface of the outer rod body of 2.6cm to 2.8cm and a maximum width w of the outer rod body of 2.5cm to 3.0cm, which can maximize the load-bearing capacity and bending resistance of the drying rack while meeting the hanging needs of clothes hangers.

[0031] (5) A reinforced drying rack of this utility model is provided with an inner rib for limiting the inner rod on the inner side wall of the outer rod body, and an inner boss on the lower side of the outer rod body. The inner rod body is a square tube or a round tube, and the outer side wall of the inner rod body is in contact with the upper and lower side walls of the outer rod body, which improves the combined stability of the inner and outer rod bodies and the overall bending strength of the drying rack.

[0032] (6) The present invention provides a reinforced drying rod, which also includes a lifting block, a connecting block and a locking bolt. The cooperation of the lifting block and the connecting block ensures the reliability of the hanging connection of the drying rod and facilitates the disassembly and maintenance of the drying rod. At the same time, the lifting block and the connecting block can restrict the degree of freedom of the length direction of the inner and outer rods, further ensuring the stability of the cooperation between the inner and outer rods, giving full play to the complementary role of the two, and improving the overall bending strength of the drying rod.

[0033] (7) A reinforced drying rod of the present invention has a buckle groove on its end cap and a buckle hook that can be connected to the buckle groove at one end of the connecting block near the end cap.

[0047] 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.

[0048] [Example 1]

[0049] Combination Figures 1 to 4 As shown, this embodiment of a reinforced clothes drying rack includes an outer rod body 1, an inner rod body 5, and end caps 2. The outer rod body 1 is made of a hollow profile rod, and its interior has rod cavities 1-4 that can accommodate the inner rod body 5. The inner rod body 5 passes through the rod cavities 1-4 of the outer rod body 1, forming a double-layered reinforced structure. The end caps 2 are respectively located at both ends of the outer rod body 1. Compared with the existing clothes drying rack structure, the reinforced clothes drying rack of this embodiment utilizes the combination of the outer rod body 1 and the inner rod body 5 to form a double-layered reinforced structure, which greatly improves the structural strength of the clothes drying rack without increasing the cross-sectional dimensions of the clothes drying rack, improves the load-bearing capacity and bending resistance of the clothes drying rack, and solves the problem of easy bending and deformation of long clothes drying racks suspended at both ends. Furthermore, due to the increased strength of the clothes drying rack, it can be used for clothes drying racks without vertical hanging boards, which helps to reduce the overall height of the clothes drying rack and makes the structure of the entire clothes drying rack more compact.

[0050] like Figure 1 As shown, in this embodiment, the outer rod 1 is also provided with a hanging groove structure for hanging clothes. Generally, this hanging groove structure is located on the upper side of the outer rod 1, which facilitates the hanging of clothes. (Refer to...) Figure 2 As shown, specifically, the upper side of the outer rod 1 is provided with a sliding groove 1-1 extending along the length direction. The sliding groove 1-1 is preferably a T-shaped groove. Several hanging sliders 3 are provided within the sliding groove 1-1. The lower part of each hanging slider 3 has a T-shaped sliding seat adapted to the T-shaped groove. Several hanging sliders 3 form a spaced-apart hanging groove. Using the above-mentioned hanging groove structure, the structure is simple and easy to manufacture. The number of hanging grooves can be flexibly adjusted as needed. Furthermore, the height of the hanging sliders 3 is small, further reducing the overall height of the drying rack. In addition, the sliding groove structure can act as a reinforcing rib, further improving the bending strength of the outer rod 1. Figure 5 As shown, in this embodiment, the height distance h between the bottom of the hanging groove and the bottom surface of the outer rod 1 is preferably 2.6cm to 2.8cm, and the maximum width w of the outer rod 1 is preferably 2.5cm to 3.0cm. This can maximize the load-bearing capacity and bending resistance of the drying rod while meeting the hanging needs of the clothes hanger hook.

[0051] In this embodiment of the reinforced drying rack, the outer rod 1 is preferably made of aluminum alloy profile, and the inner rod 5 is preferably made of steel pipe. The outer rod 1 has a convenient structural design and good material texture; the inner rod 5 has high strength, strong load-bearing capacity, and low material cost. Figures 6 to 9 As shown, the inner wall of the outer rod 1 is also provided with inner ribs 1-2 for limiting the inner rod 5, which can keep the inner rod 5 in a centered state; the lower side of the outer rod 1 is also provided with an inner boss 1-3. The inner rod 5 is a square tube or a round tube, and the outer wall of the inner rod 5 contacts and fits with the upper and lower side walls of the outer rod 1, which improves the combined stability of the inner and outer rods and the overall bending strength of the drying rack. Figure 6 and Figure 8 This illustration shows an embodiment where the inner rod 5 is a square tube. Figure 9 The illustration shows an embodiment where the inner rod 5 is a circular tube.

[0052] catch Figure 2 and Figure 3As shown, the reinforced drying rack of this embodiment also includes a lifting block 4, a connecting block 6, and a locking bolt 8. The lifting block 4 is used to connect the steel wire rope 9 to realize the suspension connection of the drying rack. The lifting block 4 is provided with a positioning post 4-1. The two ends of the outer rod body 1 and the inner rod body 5 are respectively provided with upper insertion holes that cooperate with the positioning post 4-1, so as to restrict the movement of the outer rod body 1 and the inner rod body 5 along the length direction through the positioning post 4-1. The upper side of the connecting block 6 is provided with a positioning post 4-1 that cooperates with the above-mentioned positioning post 4-1. The positioning hole has a countersunk hole on the lower side that communicates with the positioning hole. The connecting block 6 is installed in the cavity of the inner rod body 5. The positioning post 4-1 of the lifting block 4 passes through the upper insertion hole from top to bottom and is inserted into the corresponding positioning hole. The locking bolt 8 is used to connect the lifting block 4 and the connecting block 6. The two ends of the outer rod body 1 and the inner rod body 5 are respectively provided with lower insertion holes corresponding to the countersunk holes. The locking bolt 8 passes through the lower insertion hole and the countersunk hole from bottom to top and is locked to the positioning post 4-1. That is to say, the connecting block 6 in the rod cavity simultaneously restricts the horizontal and vertical degrees of freedom of the lifting block 4, realizing the rapid fixing of the lifting block 4. Since the wire rope 9 only needs to be connected to the lifting block 4, the connection is firm and convenient, and it is easy to disassemble and maintain. Figure 2 and Figure 3 As shown, inspection covers 7 are provided at the lower part of both ends of the drying rod. Inspection covers 7 have plugs 7-1 on them. The inspection covers 7 are installed from bottom to top on the lower part of the drying rod so that the plugs 7-1 pass through the lower insertion holes and are inserted into the countersunk holes. The inspection covers 7 can cover the countersunk holes and locking bolts 8, improving the overall aesthetics of the drying rod and facilitating disassembly and maintenance.

[0053] like Figure 3As shown, an elastic component for adaptive leveling of the drying rod during storage is also provided between the steel wire rope 9 and the lifting block 4. This elastic component includes a compression spring 11, the upper end of which acts on the lifting block 4 and the lower end of which acts on the lower end of the steel wire rope 9. The structure is simple and compact and easy to manufacture. Through holes are also provided at the connection points between the outer rod body 1 and the inner rod body 5 and the steel wire rope 9. The connecting block 6 is provided with a receiving groove 6 corresponding to the position of the through hole. The elastic component is located in the receiving groove 6. Without increasing the height of the lifting block 4, the effective elastic extension length of the steel wire rope 9 can be guaranteed, and the leveling tolerance of the height difference between the two ends of the drying rod can be improved, that is, the elastic movement margin of the steel wire rope 9 can be increased. Due to the presence of the compression spring 11, the wire rope 9 is in an elastic stretching state within a certain range. When the wire rope 9 is subjected to greater tension, the compression spring 11 allows the wire rope 9 to be pulled a certain distance further. When there is a height difference between the two ends of the drying rack after it is retracted, the end of the drying rack corresponding to the shorter wire rope 9 is blocked, but it can be pulled further, allowing the longer wire rope 9 at the other end to be further rolled up, keeping the drying rack horizontal as a whole. This effectively solves the problem of a height difference between the two ends of the drying rack when it is retracted due to the length difference between the suspension ropes on both sides. The aforementioned elastic component also includes an end cap 10. The lower end of the wire rope 9 is provided with an end head 9-1, and the lifting block 4 is provided with a hole for the end head 9-1 to pass through. The compression spring 11 is sleeved on the lower end of the wire rope 9, and the end cap 10 is engaged with the end head 9-1 so that the lower end of the compression spring 11 abuts against the end cap 10. Specifically, the end cap 10 is convex in shape and has a rope groove on one side. The end cap 10 can be locked onto the wire rope 9 and engage with the lower end 9-1. During installation, the end 9-1 of the wire rope 9 is first passed through the small hole on the lifting block 4. Then, the compression spring 11 is fitted onto the lower end of the wire rope 9, and the end cap 10 is installed on the end 9-1. Since the outer diameter of the end cap 10 is slightly larger than the outer diameter of the compression spring 11, it can abut against the lower end of the compression spring 11. Simultaneously, the outer diameter of the upper end of the compression spring 11 is larger than the hole on the lifting block 4, so the upper end of the compression spring 11 can abut against the lower part of the lifting block 4. Furthermore, the elastic component also includes a washer 12. The washer 12 has a rope groove on one side. The washer 12 engages with the wire rope 9 and is located above the compression spring 11. The washer 12 increases the force-bearing surface of the compression spring 11 acting on the lifting block 4, improving structural stability. Since the end cap 10 is convex, when the wire rope 9 is released to the maximum extent, that is, when the compression spring 11 is compressed to the maximum extent, the top of the end cap 10 can contact the pad 12 to form a limiting effect, preventing the compression spring 11 from being over-compressed and damaged.

[0054] Further reference Figure 3As shown, the end cap 2 is provided with a snap groove 2-1, and the end of the connecting block 6 near the end cap 2 has a snap hook 6-1 that can connect with the snap groove 2-1. The snap hook 6-1 is engaged in the snap groove 2-1 to connect the end cap 2 and the connecting block 6. When the connecting block 6 is fixed, the end cap 2 can be fixed simultaneously, eliminating the need for an additional end cap fixing structure, reducing the assembly steps of the drying rod, and facilitating the assembly and manufacturing of both. In specific installation, first assemble the end cap 2 and the connecting block 6 together, and then install them together from one end of the inner rod body 5 into its cavity. Once the end cap 2 contacts the end of the outer rod body 1, it indicates that the connecting block 6 is installed in place, and subsequent assembly can then proceed.

[0055] [Example 2]

[0056] This embodiment also discloses a clothes drying rack. (Refer to...) Figure 10 As shown, the clothes drying rack includes a drying rod assembly 100 and a lifting drive mechanism 200. The lifting drive mechanism 200 has retractable steel wire ropes 9 extending from both ends. The drying rod assembly 100 is connected to the corresponding steel wire ropes 9 at both ends. The drying rod assembly 100 adopts the reinforced drying rod of Embodiment 1, which can effectively solve the problem of bending of the drying rod in existing clothes drying racks. It can use a longer drying rod, which increases the hanging space and maximum hanging weight of the clothes drying rack, and further improves the practicality of the clothes drying rack.

[0057] In this embodiment, the lifting drive mechanism 200 can be either an electric lifting drive mechanism or a hand-cranked lifting drive mechanism. Its structure and working principle are similar to existing technologies, and therefore will not be described in detail here. When the lifting drive mechanism 200 is an electric lifting drive mechanism, the bottom of its main unit also has a drying rod receiving groove capable of housing the drying rod assembly 100. When the drying rod assembly 100 is retracted to its top position, it is housed within the drying rod receiving groove. Since the height of the drying rod assembly 100 can be made smaller, the height of the main unit can be further reduced, making the overall height of the clothes rack more compact.

[0058] This utility model discloses a reinforced drying rod and clothes rack, which utilizes an outer rod and an inner rod to form a double-layered reinforced structure. Without increasing the cross-sectional dimensions of the drying rod, it greatly improves the structural strength, load-bearing capacity, and bending resistance of the drying rod, solving the problem of easy bending and deformation of long drying rods suspended at both ends. Furthermore, due to the enhanced strength of the drying rod, it can be used for drying rods without vertical hanging boards, which helps to reduce the overall height of the drying rod and makes the structure of the entire clothes rack more compact.

[0059] 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.
