Description

Technical Field

[0001] This invention relates to the field of clothes drying rack assembly technology, and more specifically to a concealed clothes drying rack assembly that is easy to install and maintain. Background Technology

[0002] Existing concealed clothes drying racks all include a main drying rack assembly, a storage shell, and a clothes drying rod. The main drying rack assembly typically includes a cord winding device, a limit travel structure, and an obstruction protection device. During use and installation, the main drying rack assembly is installed between honeycomb panels or plasterboard ceilings, the storage shell is installed flush with the grooves in the honeycomb panels or plasterboard ceilings, and the clothes drying rod is connected to the main drying rack assembly and can be stored and hidden inside the storage shell.

[0003] Existing concealed clothes drying racks are usually difficult to maintain later. They typically have a maintenance port on the side where the storage shell is installed, which is used to reach into the honeycomb panel or plasterboard ceiling to repair or replace parts of the main unit of the clothes drying rack. However, setting up a maintenance port will affect the overall aesthetics of the honeycomb panel or plasterboard ceiling, and the repair is still quite cumbersome. Therefore, there is a need to design a concealed clothes drying rack assembly that is easy to install and maintain and has a compact size. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a concealed clothes drying rack assembly that is easy to install and maintain, thereby solving the aforementioned problems.

The end of the drive shaft away from the first mounting bracket extends into the external threaded sleeve and is rotatably connected to it. The internal thread is fixed inside the winding sleeve and threadedly connected to the external thread. The connecting shaft, the shaft-shaped reducer, and the motor are connected in sequence.

[0017] Furthermore, the elastic rope pressing assembly includes a rope pressing shaft and two rope pressing seats. The two rope pressing seats are fixed on a fixed base, and each rope pressing seat is provided with a waist-shaped through hole and a spring hole communicating with the waist-shaped through hole. The rope pressing shaft is located between the two rope pressing seats, and both ends of the rope pressing shaft extend into the waist-shaped through holes of the two rope pressing seats respectively. A third spring is provided in the spring hole of each of the two rope pressing seats. One end of the third spring is fixedly connected to the rope pressing seat, and the other end contacts and abuts against the rope pressing shaft. A tightening sleeve is fitted on the rope pressing shaft, and the tightening sleeve abuts against the lifting rope wound on the winding sleeve.

[0018] Furthermore, the mounting structure includes a U-shaped opening groove and waist-shaped mounting holes located on both sides of the U-shaped opening groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention, by setting up a housing, a guiding and protective structure, and a winding device, and by designing the housing as a long strip, the winding device as a long shaft that is conveniently installed inside the housing along its length, and the guiding and protective structure installed at both ends of the housing, can reduce the width of the clothes drying rack assembly. This makes the overall width of the clothes drying rack assembly extremely small (narrow) compared to existing clothes drying rack assemblies. This allows for the installation of a recess larger than the width of the product after pre-reserving a groove in the honeycomb panel or gypsum board ceiling. This enables installation and maintenance without removing the ceiling, and eliminates the need for a maintenance opening on one side of the groove. This product improves the aesthetics of honeycomb panel or gypsum board ceilings. Furthermore, the guide protection structure is integrated into the mounting base, comprising an upper limit travel structure, an obstruction protection device, and a first guide wheel mounted on the base. This significantly reduces the overall size of the guide protection structure. During maintenance, the mounting base can be directly removed for easy repair or replacement of the upper limit travel structure, obstruction protection device, or first guide wheel. Moreover, while ensuring a minimum length, the length of the clothes drying rack assembly can be customized to fit various lengths of clothes drying rods. Attached Figure Description

[0035] In the description of this invention, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this invention, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0037] A concealed clothes drying rack assembly that is easy to install and maintain includes a housing 1, a guide and protection structure 2, two hanging ropes 5, an electrical control box 6, and a cord reel device 3;

[0038] The housing 1 is elongated, and mounting structures 4 are provided at both ends of the housing 1;

[0039] The winding device 3 is in the shape of a long shaft and is conveniently installed inside the housing 1 along the length of the housing 1, and is used to wind and unwind the suspension rope 5.

[0040] The guide protection structure 2 is installed at both ends of the housing 1, and the guide protection structure 2 includes a mounting base 23 and an upper limit travel structure 21, an obstruction protection device 22 and a first guide wheel 24 installed on the mounting base 23. The mounting base 23 is detachably connected to the housing 1. The upper limit travel structure 21 can contact the clothes drying rod and is used to control the upper limit travel of the clothes drying rod. The first guide wheel 24 is used to guide the hanging rope 5 around. The obstruction protection device 22 is connected to the first guide wheel 24 and is used to control the winding device 3 to stop working when the clothes drying rod encounters obstruction.

[0041] This invention, by setting up a housing 1, a guiding and protective structure 2, and a winding device 3, and by designing the housing 1 as a long strip and the winding device 3 as a long shaft that is conveniently installed inside the housing 1 along its length, and by installing the guiding and protective structure 2 at both ends of the housing 1, can reduce the width of the clothes drying rack assembly. This makes the overall width of the clothes drying rack assembly significantly smaller (narrower) compared to existing clothes drying rack assemblies. This allows for the installation of the clothes rack after reserving a groove larger than the width of the product in the honeycomb panel or gypsum board ceiling, enabling installation and maintenance without dismantling the ceiling. Furthermore, it eliminates the need for a maintenance opening on one side of the groove, improving the aesthetics of the honeycomb panel or gypsum board ceiling. Additionally, the guiding and protective structure... The design includes a mounting base 23 and an upper limit travel structure 21, an obstruction protection device 22, and a first guide wheel 24 mounted on the mounting base 23. This integrates the entire guide protection structure 2 onto the mounting base 23, significantly reducing the overall size of the guide protection structure 2. During maintenance, the mounting base 23 can be directly removed to repair or replace the upper limit travel structure 21, the obstruction protection device 22, or the first guide wheel 24, making maintenance convenient. Furthermore, this product allows for customization of the length of the clothes drying rack assembly while ensuring a minimum length, thus adapting to clothes drying rods of various lengths. Due to its small size, it is easy to install and can be applied to various scenarios, such as balconies, bathrooms, hotel apartments, and walk-in closets.

[0042] In this embodiment, the preferred embodiment is as follows: Figure 2-4 As shown, the upper limit travel structure 21 includes a contact post and a limit micro switch 2101. The limit micro switch 2101 is fixed in the mounting base 23. One end of the contact post extends into the mounting base 23 and is vertically slidably connected to the mounting base 23. The extended end of the contact post can contact and cooperate with the limit micro switch 2101. The end of the contact post away from the limit micro switch 2101 extends out of the housing 1 and can contact the clothes drying rod.

[0043] In this embodiment, the preferred embodiment is as follows: Figure 2 and Figure 4 As shown, the top of the mounting base 23 is provided with a first receiving groove 2110, and the bottom of the mounting base 23 is provided with a sliding groove 2109 communicating with the first receiving groove 2110. The limit micro switch 2101 is fixed in the first receiving groove 2110. One end of the contact post extends into the sliding groove 2109 and slides vertically. The contact post can contact and cooperate with the limit micro switch 2101. The bottom of the mounting base 23 is also provided with an anti-detachment structure to prevent the contact post from detaching.

[0044] In this embodiment, the preferred embodiment is as follows: Figure 6As shown, a first spring groove 2114 is provided on the side of the sliding groove 2109 that communicates with the first receiving groove 2110. A second spring 2115 is provided in the first spring groove 2114. The second spring 2115 abuts against the extended end of the contact post and is used to push the contact post away from the limit micro switch 2101. Specifically, by providing the second spring 2115, when the clothes drying rod rises without pushing against the contact post, the contact post will automatically move away from the limit micro switch 2101 under the elastic force of the second spring 2115. This effectively prevents the contact post from contacting the limit micro switch 2101 in other accidental situations, and also prevents the contact post from getting stuck and not automatically falling away from the limit micro switch 2101 under the action of gravity when the clothes drying rod rises after pushing against the contact post.

[0045] In this embodiment, the preferred embodiment is as follows: Figure 4 As shown, the contact column includes an outer column 2102 and an inner column 2103. One end of the inner column 2103 extends into the outer column 2102 and is axially slidably connected to the outer column 2102. A telescopic adjustment device is provided between the inner column 2103 and the outer column 2102. By setting the contact column as an outer column 2102 and an inner column 2103, and providing a telescopic adjustment device between the inner column 2103 and the outer column 2102, the overall length of the contact column (outer column 2102 and inner column 2103) can be adjusted, thereby changing the height of the clothes drying rod when it contacts the contact column, and thus changing the position of the upper limit stroke of the clothes drying rod.

[0046] In this embodiment, the preferred embodiment is as follows: Figure 4 As shown, the outer column 2102, at the end away from the inner column 2103, is sequentially provided with an anti-rotation nut groove 2107 and a through hole 2113. The inner column 2103, at the end away from the outer column 2102, is provided with a second through hole 2112. The telescopic adjustment device includes an adjusting bolt 2104, an adjusting nut 2106, and an adjusting spring 2105. The adjusting nut 2106 is located in the anti-rotation nut groove 2107, and the adjusting bolt 2104 passes sequentially through the second through hole. 2112 and the first through hole 2113 are threadedly connected to the adjusting nut 2106. The adjusting spring 2105 is fitted on the adjusting bolt 2104 and is located between the inner post 2103 and the outer post 2102, respectively abutting against the inner post 2103 and the outer post 2102. Specifically, the overall length of the inner post 2103 and the outer post 2102 (contact post) can be adjusted by rotating the adjusting bolt 2104 and under the elastic force of the adjusting spring 2105.

[0047] In this embodiment, the preferred embodiment is as follows: Figure 3-4As shown, the bottom of the mounting base 23 is provided with openings on both sides of the sliding groove 2109, and an elastic buckle 2108 is provided at the opening. The elastic buckle 2108 can be fastened to the end where the outer post 2102 and the inner post 2103 are connected, thereby preventing the contact post from detaching from the sliding groove 2109.

[0048] In this embodiment, the preferred embodiment is as follows: Figure 3 As shown, a directional marking 2111 is provided on the end face of the inner column 2103 away from the outer column 2102; the directional marking 2111 includes a clockwise rotating arrow, a counterclockwise rotating arrow, "up" and "down", the "up" marking is located below the clockwise rotating arrow, indicating that rotating the adjusting bolt 2104 clockwise will extend the inner rod and increase the total length of the contact column; the "down" marking is located below the counterclockwise rotating arrow, indicating that rotating the adjusting bolt 2104 counterclockwise will retract the inner rod and shorten the total length of the contact column.

[0049] The working principle of the upper limit travel structure 21: In actual use, the upper limit travel structure 21 is installed at both ends of the housing 1 of the clothes drying rack, and the end of the contact post extending out of the sliding groove 2109 faces downward. When the clothes drying rod is driven to rise to the upper limit travel position by the winding device 3, the clothes drying rod will contact the bottom of the contact post (the end facing downward). Then the contact post will be pushed upward by the clothes drying rod, and finally the contact post will contact the limit micro switch 2101, so that the limit micro switch 2101 receives the signal and transmits it to the winding device 3, so that the winding device 3 stops working, thereby stopping the clothes drying rod at the upper limit travel position.

[0050] In this embodiment, the preferred embodiment is as follows: Figure 2-5 As shown, the top of the mounting base 23 is provided with a mounting groove 2201. The first guide wheel 24 is fitted with a rotating shaft, and the rotating shaft and the first guide wheel 24 are located in the mounting groove 2201. The rotating shaft can move up and down in the mounting groove 2201. The bottom of the mounting groove 2201 is provided with a second receiving cavity and a second spring groove 2204. The obstruction detection micro switch 2203 is located in the second receiving cavity. The rotating shaft can contact the obstruction detection micro switch 2203. A first spring is provided in the second spring groove 2204. The first spring contacts and abuts against the rotating shaft, and is used to drive the rotating shaft away from the obstruction detection micro switch 2203 without external force. The bottom of the mounting base 23 is provided with a through hole 2202 communicating with the mounting groove 2201. The through hole 2202 is used to allow the hanging rope 5 to pass through the first guide wheel 24 and then through the through hole 2202 to connect downward to the clothes drying rod.

[0051] In this embodiment, the preferred embodiment is as follows: Figure 5As shown, an anti-detachment protrusion 2205 is provided above one side of the rotating shaft in the mounting groove 2201. The anti-detachment protrusion can contact the rotating shaft to prevent the rotating shaft (and the first guide wheel 24) from detaching from the mounting groove 2201.

[0052] Working principle of obstacle detection protection device 22: In actual use, such as Figure 2 As shown, the hanging rope 5 in the winding device 3 extends out from the winding device 3, enters the mounting groove 2201 from the top side of the mounting base 23, and winds around the first guide wheel 24. Then, it extends vertically downward from the guide hole 2202 and connects to the clothes drying rod. During normal rise and fall of the clothes drying rod, the clothes drying rod is pulled by gravity through the hanging rope 5, keeping the first guide wheel 24 at the lowest point in the mounting groove 2201 and keeping the shaft in contact with the obstruction detection micro switch 2203. When the clothes drying rod encounters obstruction during descent, the first guide wheel 24 is no longer pulled by the gravity of the clothes drying rod, and the first spring will push up the shaft, so that the shaft is no longer in contact with the obstruction detection micro switch 2203. Then, the obstruction detection micro switch 2203 receives the signal and transmits it to the winding device 3, causing the winding device 3 to stop working, thereby completing the obstruction detection protection of the clothes drying rod.

[0053] In this embodiment, the preferred embodiment is as follows: Figure 7-11 As shown, the winding device 3 includes a fixed base 303, an elastic rope pressing assembly, a winding guide assembly, and a motor 301, a shaft-shaped reducer 302, and a shaft-shaped winding assembly connected in sequence. The fixed base 303 is provided with a winding cavity 327, and the shaft-shaped winding assembly is located within the winding cavity 327. A communicating guide groove 326 is provided on one side of the fixed base 303 located within the winding cavity 327. The winding guide assembly includes two second guide wheels 323, which are located within the guide groove 326. The wheel 323 is rotatably and detachably connected to the fixed base 303. Both ends of the fixed base 303 are provided with guide holes 328 that communicate with the guide groove 326. Two suspension ropes 5 are wound around the shaft-shaped winding assembly. One end of the two suspension ropes 5 is fixedly connected to the winding assembly, and the other end extends into the guide groove 326 and is wound around the two second guide wheels 323 respectively. Then they extend out from the two guide holes 328 respectively. The elastic rope pressing assembly is installed on the fixed base 303 and is located on one side of the shaft-shaped winding assembly. It is used to press the suspension ropes 5 on the shaft-shaped winding assembly.

[0054] By mounting the axial winding assembly, guide assembly, and elastic cord pressing assembly on the fixed base 303, the entire winding device 3, except for the axial reducer 302 and motor 301, is integrated and mounted on the fixed base 303. This facilitates installation and subsequent maintenance of the winding device 3; maintenance can be performed simply by removing the fixed base 303. Furthermore, by providing a winding cavity 327 and a guide groove 326 on the fixed base 303, the axial winding assembly is installed in the winding cavity 327, and the guide assembly is installed in the winding groove. This provides a certain degree of protection for the axial winding assembly and the guide assembly, preventing interference and ensuring their normal operation.

[0055] In this embodiment, the preferred embodiment is as follows: Figure 10 As shown, two fixed shafts 324 are respectively provided in the guide groove 326, and two second guide wheels 323 are respectively mounted on the two fixed shafts 324 for rotational connection. A groove cover 321 is provided on the outside of the guide groove 326 and the two second guide wheels 323. The groove cover 321 closes the guide groove 326 and is detachably connected to the fixed seat 303. By providing the groove cover 321, the guide groove 326 can be closed to protect the second guide wheels 323 and prevent interference with the rotation of the second guide wheels 323 and the sliding and winding of the lifting rope 5. Furthermore, the groove cover 321 is detachably connected to the fixed seat 303, and the guide wheels in the guide groove 326 can be repaired or replaced by removing the groove cover 321.

[0056] In this embodiment, the preferred embodiment is as follows: Figure 10 As shown, a mounting post 325 is provided in the guide groove 326, and a mounting threaded hole is provided on the mounting post 325. A mounting through hole 322 is provided on the groove cover 321, and a mounting bolt is provided in the mounting through hole 322. The mounting bolt passes through the mounting through hole 322 and extends into the mounting threaded hole, so that the groove cover 321 is detachably connected to the fixing base 303.

[0057] In this embodiment, the preferred embodiment is as follows: Figure 7-9As shown, the shaft-shaped winding assembly includes a winding sleeve 304, a rotating shaft 307, an internal threaded sleeve 311, and an external threaded sleeve 305. A first mounting bracket 314 and a second mounting bracket 315 are respectively provided at both ends of the fixed base 303. The winding cavity 327 is located between the first mounting bracket 314 and the second mounting bracket 315. One end of the rotating shaft 307 is rotatably connected to the first mounting bracket 314 and extends out of the first mounting bracket 314, where a connecting shaft 310 is fixedly connected. The winding sleeve 304 is fitted onto the rotating shaft 307 and rotates... The moving shaft 307 is axially slidably connected and circumferentially fixed. The lifting rope 5 is wound around the winding sleeve 304, and one end of the lifting rope 5 is engaged with the winding sleeve 304. One end of the external threaded sleeve 305 is fixedly connected to the second mounting bracket 315. The end of the rotating shaft 307 away from the first mounting bracket 314 extends into the external threaded sleeve 305 and is rotatably connected to the external threaded sleeve 305. The internal thread is fixed in the winding sleeve 304 and threadedly connected to the external thread. The connecting shaft 310, the shaft-shaped reducer 302, and the motor 301 are connected in sequence.

[0058] Specifically, when the motor 301 starts, it drives the connecting shaft 310 to rotate through the shaft reducer 302. The connecting shaft 310 then drives the rotating shaft 307 to rotate, causing the winding sleeve 304 to rotate accordingly. This allows the hanging rope 5 to be wound or unwound, thus achieving the winding function. At the same time, the internal threaded sleeve 311 also rotates, causing the winding sleeve 304 to move axially.
