Description

Technical Field

[0001] This invention belongs to the field of clothes drying racks, and more specifically, relates to a telescopic mechanism for a clothes drying rod and a clothes drying rack. Background Technology

[0002] With market diversification and consumer demands for product performance, appearance, and features such as built-in or integrated installation, as well as considerations for limited balcony space, products need to be smaller and have a larger drying capacity. Therefore, not only does the main unit need to be as concealed as possible, but the drying racks also require further optimization to improve aesthetics and drying capacity. Existing drying racks typically increase drying capacity by simultaneously installing clotheslines and quilt drying racks.

[0003] For example, utility model patent "CN210975260U" discloses "a single-pole clothes drying rack, including a main unit, a telescopic frame, and a drying rod assembly; the main unit includes an installation strip, and the bottom of the installation strip is provided with a first telescopic frame sliding groove; the drying rod assembly includes a drying rod and a second telescopic frame sliding groove, the second telescopic frame sliding groove being located on the upper part of the drying rod; the upper part of the telescopic frame is connected to the first telescopic frame sliding groove via a first sliding wheel, and the lower part of the telescopic frame is connected to the second telescopic frame sliding groove via a second sliding wheel, the telescopic frame being slidable within the first and second telescopic frame sliding grooves. Using this utility model can enhance the wind resistance of the drying rod and strengthen the connection between the steel wire rope and the drying rod."

[0004] For example, utility model patent "CN219886395U" discloses "a single-pole clothes drying rack that facilitates the placement of a clothes rack, including a main body, a drive component disposed in the main body, and a drying component connected to the drive component via a connecting rope. The bottom of the main body has a storage cavity with an opening facing downwards; a clothes rack is hung on the drying component, and the longitudinal width of the hook of the clothes rack is smaller than the opening width of the storage cavity, so that the hook of the clothes rack and the drying component can be simultaneously accommodated in the storage cavity. In this utility model, by changing the opening width of the storage cavity, it is possible to store and hide the drying component without removing the clothes rack, while still being able to dry clothes, thereby increasing the clearance space under the single-pole clothes drying rack and facilitating user passage."

[0005] The above-mentioned existing technologies have the following problems:

[0006] (1) The connection between clothes drying rod and quilt drying rod is often that the quilt drying rod is placed on the clothes drying rod when stored. When using it, the entire quilt drying rod needs to be flipped down. This requires a large range of operations and is not visually natural or beautiful. It may even affect the use of the clothes drying rod when used alone.

[0007] (2) Alternatively, when connecting and separating the clothes drying rod and the quilt drying rod, a complex connection structure and complicated operation steps are required, resulting in a poor user experience. Moreover, the numerous and cumbersome connection structures greatly affect the aesthetics of the clothes drying machine. Summary of the Invention

[0018] The push rod is fixedly installed at the bottom of the pressing block;

[0019] The limiting hook is fixedly installed at the bottom of the fixing nail, and the bottom of the limiting hook is bent and extends horizontally.

[0020] As a further improvement of the present invention, the limiting end includes a limiting block, and a card plate extends horizontally on the inner wall of the lower end cover. The limiting block is slidably mounted on the card plate. A second elastic member supporting the limiting block is fixedly mounted at the bottom of the inner wall of the lower end cover. The limiting block and the push rod are located in the same vertical direction.

[0021] The card plate is provided with a through groove running vertically through it. One end of the bottom of the limiting hook extends horizontally into the through groove, and one side of the limiting block extends vertically downward and into the through groove. The limiting hook is located between the side wall of the limiting block and the through groove.

[0022] As a further improvement of the present invention, the stretching end includes a fixed block and a sliding block;

[0023] The fixed block is fixed to the inner wall of the clothes rod, and the sliding block is slidably mounted to the inner wall of the clothes rod.

[0024] The sliding block has a through cavity running vertically on one side, and both the sliding block and the connecting hook have wedge-shaped surfaces on their respective end faces that are close to each other. The sliding block and the connecting hook are detachably connected.

[0025] As a further improvement of the present invention, the first elastic element includes a connecting spring, one end of which is detachably connected to the fixed block, and the other end of which is detachably connected to the side of the sliding block near the fixed block.

[0026] As a further improvement of the present invention, the rope body includes a connecting rope, one end of which is fixedly disposed with the sliding block, and the other end of which passes through the upper end cap and the lower end cap near one side and is fixedly disposed with the end of the inner rod assembly on both sides away from each other.

[0027] As a further improvement of the present invention, the inner rod assembly includes two inner rods, both of which are slidably disposed within the rod, and the ends of the two inner rods that are far apart from each other are respectively fixedly disposed with two connecting ropes.

[0028] As a further improvement of the present invention, a first locking block is provided at one end of the two inner rods that are close to each other. The first locking block is slidably connected to the inner rods and can extend out of the inner rods.

[0029] A spring is fixedly installed inside the inner rod, and the elastic release end of the spring is fixedly installed with the first locking block;

[0030] A protruding second locking block is fixedly installed on one side of the inner rod, and a baffle is provided at the end of the rod to limit the movement of the second locking block.

[0031] As a further improvement of the present invention, a clothes drying machine is used according to the telescopic mechanism of the drying rod, including a main unit, an electric drive device is provided inside, and a retractable steel wire rope is provided on the electric drive device.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] For specific implementation examples, please refer to: Figure 1-12 A telescopic mechanism for a drying rack includes,

[0051] The clothes rod 13 has an upper end cap 14 at each of its two ends;

[0052] The quilt rod 16 is located below the clothes rod 13. The quilt rod 16 has an inner rod assembly that can extend to both ends. The two ends of the inner rod assembly are respectively provided with lower end caps 15. The upper end cap 14 and the lower end cap 15 are open on the side that is close to each other.

[0053] The retractable assembly includes a trigger end and a limiting end. The trigger end is movable up and down and is disposed inside the upper end cover 14. The top of the trigger end extends upward to the outside of the upper end cover 14, and the bottom of the trigger end extends downward to the inside of the lower end cover 15 and is detachably connected to the lower end cover 15. The limiting end is movable up and down and is disposed inside the lower end cover 15. When the limiting end is at the upper limit position, it limits the bottom of the trigger end and prevents it from moving horizontally.

[0054] The connecting rope assembly has two identical sets, each including a tension end and a rope body. The two tension ends are both located inside the clothes rod 13, with the side of the two tension ends that are close to each other fixed to the clothes rod 13, and the side of the two tension ends that are far from each other fixed to one end of the two rope bodies respectively. A first elastic element is connected between the two sides of the tension ends. The other ends of the two rope bodies are fixed to the two inner rod assemblies respectively.

[0055] It is understood that the clothes rod 13 and the quilt rod 16 are arranged vertically, and each end is provided with an identical upper end cap 14 and an identical lower end cap 15. The upper end cap 14 and the lower end cap 15 are connected, and a retractable assembly is provided to control the connection and separation between the upper end cap 14 and the lower end cap 15. The top of the trigger end extends to the upper side of the upper end cap 14, while the bottom side extends into the lower end cap 15. Therefore, the trigger end can be moved by pressing it to separate the upper end cap 14 and the lower end cap 15. At the same time, the limiting end can also move up and down. When it is in the upper limit position, that is, in the unforced state, the trigger end can be limited so that the upper end cap 14 and the lower end cap 15 remain connected. The function of the connecting rope assembly is that one end of the rope is located inside the clothes rod 13, and the other end is connected to the inner rod assembly. Therefore, when it is necessary to lower the clothes rod 16 for use, the clothes rod 13 and the clothes rod 16 can always be connected by the rope. At the same time, a first elastic element is provided between the two sides of the pull rope end. The first elastic element includes a connecting spring 22. When the clothes rod 16 is lowered, it will be pulled, and the connecting spring 22 will deform to allow the clothes rod 16 to move downward smoothly. When it is desired to move the clothes rod 16 upward and closer to the clothes rod 13, it can be automatically reset upward by the elastic pulling force of the connecting spring 22.

[0056] The trigger end includes a fixing pin 34. A horizontal plate extends horizontally on the inner wall of the upper end cover 14. The fixing pin 34 is fixedly mounted on the horizontal plate. A pressing block 31 is slidably mounted on the outer surface of the fixing pin 34. A telescopic spring 33 is provided between the pressing block 31 and the fixing pin 34. The top of the telescopic spring 33 is fixedly mounted to the pressing block 31, and the bottom of the telescopic spring 33 is fixedly mounted to the horizontal plate.

[0057] It is understood that the aforementioned horizontal plate is fixedly installed inside the bottom side of the upper end cover 14, the fixing nail 34 is fixedly installed on the horizontal plate and extends to the upper side of the horizontal plate, the outer circular surface of the fixing nail 34 extending to the upper side of the horizontal plate is fitted with a telescopic spring 33, and the top of the fixing nail 34 is slidably connected to a pressing block 31. The telescopic spring 33 only needs to be installed between the pressing block 31 and the horizontal plate, and the elastic release ends at both ends act on the pressing block 31 and the horizontal plate.

[0058] The trigger end also includes a pressing block 31, on the top of which a button 17 is detachably provided. The button 17 is slidably disposed with the top of the upper cover 14, and the top of the button 17 extends upward to the upper side of the upper cover 14. A hook-shaped connecting hook 32 is fixedly provided on one side of the pressing block 31.

[0059] It is understandable that the function of the pressing block 31 is to connect the button 17 and the elastic force of the telescopic spring 33. When the button 17 is pressed by an external force, it will push the pressing block 31 and then compress the telescopic spring 33. When the external force disappears, the elastic force of the telescopic spring 33 will cause the button 17 to extend and reset. Meanwhile, a hook-shaped connecting hook 32 is provided on the side of the pressing block 31 near the sliding block 23. The end face of the connecting hook 32 near the sliding block 23 is a wedge-shaped surface. The side of the sliding block 23 near the pressing block 31 is also provided with a wedge-shaped surface that matches it. A cavity 25 is provided to accommodate the hook of the connecting hook 32. Therefore, when the sliding block 23 and the wedge-shaped surface of the connecting hook 32 come into contact with each other, the connecting hook 32 will be driven to move downward. As the sliding block 23 moves towards the connecting hook 32, the hook of the connecting hook 32 will extend into the cavity 25, thereby forming a connection between the connecting hook 32 and the cavity 25. After the connecting hook 32 and the cavity 25 are connected, the sliding block 23 and the connecting hook 32 are fixed, thus maintaining the position and state of the sliding block 23 and keeping the connecting spring 22 in a stretched state.

[0060] The trigger end also includes a limiting hook 36 and a push rod 35; the push rod 35 is fixedly installed at the bottom of the pressing block 31; the limiting hook 36 is fixedly installed at the bottom of the fixing nail 34, and the bottom of the limiting hook 36 is bent and extends horizontally.

[0061] It is understood that the push rod 35 is fixedly installed at the bottom end of the pressing block 31, and the push rod 35 is slidably connected to the horizontal plate through it. When the button 17 is pressed, the pressing block 31 moves downward and drives the push rod 35 to move downward and extend into the lower end cover 15. The limiting hook 36 is fixed to the horizontal plate by the part of the fixing nail 34 located on the lower side of the horizontal plate. The limiting hook 36 is in a vertical state and its bottom end is bent and extended horizontally so that the limiting hook 36 is also hook-shaped. The limiting hook 36 can extend into the lower end cover 15 and connect with the through-slot hook on the card plate.

[0062] The limiting end includes a limiting block 37, and a card plate extends horizontally on the inner wall of the lower end cover 15. The limiting block 37 is slidably mounted on the card plate. A second elastic element supporting the limiting block 37 is fixedly mounted at the bottom of the inner wall of the lower end cover 15. The limiting block 37 and the push rod 35 are located in the same vertical direction. A through groove is provided on the card plate. One end of the limiting hook 36 extends horizontally from the bottom and enters the through groove. One side of the limiting block 37 extends vertically downward and enters the through groove. The limiting hook 36 is located between the limiting block 37 and the side wall of the through groove.

[0063] It is understood that the aforementioned card plate includes a connecting plate 38, which has a through groove running vertically through it. A limiting block 37 is slidably connected to the connecting plate 38 vertically. A second elastic element, including a movable spring 39, is connected to one end of the limiting block 37 located on the lower side of the connecting plate 38. When the limiting block 37 is pressed down by an external force, it compresses the movable spring 39 to allow the limiting block 37 to move downward smoothly. When the external force disappears, the limiting block 37 automatically rebounds upward through the movable spring 39. The main body of the limiting block 37 is horizontal and located in the same vertical direction as the push rod 35. Therefore, when the push rod 35 moves downward, it pushes the limiting block 37 downward. One end of the limiting block 37 extends vertically downward and can be inserted into the through groove of the connecting plate 38 to limit the hook of the limiting hook 36 in the horizontal direction.

[0064] The stretching end includes a fixed block 21 and a sliding block 23; wherein, the fixed block 21 is fixedly installed on the inner wall of the clothes rod 13, and the sliding block 23 is slidably installed on the inner wall of the clothes rod 13; a through cavity 25 is provided on one side of the sliding block 23, and the end faces of the sliding block 23 and the connecting hook 32 that are close to each other are provided with inclined wedge surfaces, and the sliding block 23 and the connecting hook 32 are detachably connected.

[0065] It is understood that the aforementioned fixed block 21 is the fixed end inside the clothes rod 13, and the sliding block 23 is the moving end inside the clothes rod 13. The sliding block 23 is provided with a wedge-shaped surface that cooperates with the connecting hook 32 on the side near the pressing block 31, and the through cavity 25 is open from top to bottom to accommodate the hook of the connecting hook 32. Therefore, when the sliding block 23 and the wedge-shaped surface of the connecting hook 32 come into contact with each other, the connecting hook 32 will be driven to move downward. Thus, by the continuous movement of the sliding block 23 toward the connecting hook 32, the hook of the connecting hook 32 will extend into the through cavity 25, thereby forming a connection between the connecting hook 32 and the through cavity 25. After the connecting hook 32 and the through cavity 25 are connected, the sliding block 23 and the connecting hook 32 are fixed, thus maintaining the position and state of the sliding block 23 and keeping the connecting spring 22 in a stretched state.

[0066] The first elastic element includes a connecting spring 22, one end of which is detachably connected to the fixing block 21, and the other end of which is detachably connected to the sliding block 23 on the side near the fixing block 21.

[0067] It is understood that both ends of the connecting spring 22 are hook-shaped, so the two ends of the connecting spring 22 are hook-shaped connected to the fixed block 21 and the sliding block 23 respectively.

[0068] The rope body includes a connecting rope 24. One end of the connecting rope 24 is fixedly disposed with the sliding block 23, and the other end of the connecting rope 24 passes through the upper end cover 14 and the lower end cover 15 on one side and is fixedly disposed with the end of the inner rod assembly on both sides away from each other.

[0069] It is understood that the top end of the connecting rope 24 is located inside the clothes rod 13 and is connected to the sliding block 23 so that it can slide inside the clothes rod 13, while the bottom end of the connecting rope 24 extends downward through the lower end cover 15 and is fixedly installed at the telescopic end of the inner rod 18.

[0070] The inner rod assembly includes two inner rods 18, both of which are slidably disposed within the rod 16. The ends of the inner rods 18 that are far apart from each other are respectively fixed to two connecting ropes 24.

[0071] It is understood that the inner rods 18 are respectively located at both ends inside the rod 16, and can extend from both ends of the rod 16 to the outside of the rod 16 through the connection with the rod 16. The ends of the two inner rods 18 that are far apart from each other are respectively fixedly set to the two lower end caps 15.

[0072] Two inner rods 18 are provided with a first locking block 42 at one end close to each other. The first locking block 42 is slidably connected to the inner rods 18 and can extend out of the inner rods 18. A spring 41 is fixedly provided inside the inner rods 18. The elastic release end of the spring 41 is fixedly provided with the first locking block 42. A protruding second locking block 43 is fixedly provided on one side of the inner rods 18. A baffle is provided at the end of the rod 16 to limit the movement of the second locking block 43.

[0073] It is understandable that the first locking block 42 and the second locking block 43 are configured such that when the inner rod 18 extends out of the rod 16, the first locking block 42 is unobstructed and can therefore pop upward out of the inner rod 18. At this time, the two ends of the rod 16 are respectively provided with baffles corresponding to the two second locking blocks 43. The baffles can be protrusions on the inner wall of the rod 16. The baffles include a limiting plate 44. When the first locking block 42 extends, the limiting plate 44 simultaneously abuts against the second locking block 43. At the same time, the two first locking blocks 42 abut against the two ends of the rod 16. Therefore, by limiting the two ends of the first locking block 42 and the second locking block 43, the further extension and natural retraction of the inner rod 18 are restricted.

[0074] A clothes drying rack, used according to the telescopic mechanism of the drying rod, includes a main unit 11, which is equipped with an electric drive device. The electric drive device is equipped with a retractable steel wire rope 12. The two ends of the steel wire rope 12 extend downward from the two ends of the bottom side of the main unit 11, and the bottom ends of the two steel wire ropes 12 are fixedly installed on the top of the two upper end caps 14.

[0075] It is understood that the electric drive device in the main unit 11 includes conventional clothes drying rack components such as a motor, controller and reel. The controller can receive external electrical signals to start the motor. The motor starts and drives the reel to rotate, thereby controlling the extension or retraction of the wire rope 12 by different rotation directions, and thus controlling the rise or fall of the upper cover 14.

[0076] It is worth noting that, such as Figure 1 As shown, there are two sets of the same number of clothes rods 13 and quilt rods 16. The main unit 11 can be equipped with multiple steel wire ropes 12 to provide traction for the clothes rods 13 and quilt rods 16.

[0077] Working principle: In the initial state, such as Figure 1 As shown, the top of the main unit 11 is fixed to the ceiling of the room by expansion screws. The upper end cover 14 and the lower end cover 15 are connected and fitted together. The clothes rod 13 and the quilt rod 16 are close to each other, and the clothes rod 13 and the main unit 11 are close to each other.

[0078] Furthermore, when needed, the motor can be remotely started via a remote control or buttons to rotate the winding reel, thereby releasing the wire rope 12. After the wire rope 12 is released, the clothes rod 13 and the blanket rod 16 move downwards under their own weight until they reach a height convenient for the user to operate at, and then stop. (Refer to...) Figure 7-8 Manually press the buttons 17 on both sides. The buttons 17 move down, which pushes the pressing block 31 to compress the telescopic spring 33 and move it down. This, in turn, drives the push rod 35 to move down, pushing the limiting block 37 to compress the moving spring 39 and move it down. After the limiting block 37 moves down, the vertical bending of the limiting block 37 moves the part of the limiting hook 36 that is limited out of the through groove of the connecting plate 38. Therefore, the limiting hook 36 will no longer be limited in the horizontal direction. At this time, manually pull the lower end caps 15 on both sides to move away from the rod 16. After the two lower end caps 15 move, the connecting plate 38 moves synchronously, so that the hook connection between the limiting hook 36 and the connecting plate 38 is disengaged, allowing the limiting hook 36 to extend out of the connecting plate 38 and disengage from the lower end cap 15.

[0079] Furthermore, such as Figure 9-11As shown, at this time, the clothes rod 13 and the quilt rod 16 are disconnected and can be moved away from each other, so as to be used as two separate drying rods. Clothes and quilts can be dried separately, increasing the amount of laundry and expanding the drying area. When you want the clothes rod 13 and the quilt rod 16 to be separated to their maximum distance, manually pull down the quilt rod 16 to overcome the tension of the connecting spring 22, causing the sliding blocks 23 on both sides to slide towards the side away from each other. At this time, the connecting rope 24 continuously extends outward from inside the clothes rod 13 to continuously connect the clothes rod 13 and the quilt rod 16. As the sliding block 23 continues to slide, it causes the wedge surface and the wedge surface of the connecting hook 32 to come into contact with each other. Through the wedge force, the connecting hook 32 is driven to compress the telescopic spring 33 and move downward. Then, through the continuous movement of the sliding block 23 towards the connecting hook 32, the connecting hook 32... The hook moves to the bottom of the cavity 25. At this time, the connecting hook 32 is no longer pressed down, and the connecting hook 32 is pushed into the cavity 25 by the thrust of the telescopic spring 33, so that the connecting hook 32 and the cavity 25 are connected. After the connecting hook 32 and the cavity 25 are connected, the sliding block 23 and the connecting hook 32 are fixed, so the position and state of the sliding block 23 can be maintained, and the connecting spring 22 is always kept in the stretched state. At this time, the clothes rod 13 and the quilt rod 16 are at the position with the largest gap. Clothes can be hung on the clothes rod 13 and large items such as quilts can be hung on the quilt rod 16.

[0080] Furthermore, such as Figure 12 As shown, large items such as quilts can be hung on the quilt rod 16. When the length of the quilt rod 16 is insufficient to hang larger items, the two lower end caps 15 can be manually pulled further out to the side away from each other, so that the inner rods 18 on both sides extend out from both ends of the quilt rod 16. When the inner rods 18 extend out, the first locking block 42 moves and contacts the limiting plate 44. At this time, since one end face of the first locking block 42 is provided with an inclined surface, the inclined surface contacts the limiting plate 44, which causes the first locking block 42 to move downward. When the first locking block 42 moves outside the quilt rod 16, since it loses the cover of the inner wall of the quilt rod 16, the elasticity of the spring 41 pushes the first locking block 42 out to the outside of the inner rod 18. The extension of the first locking block 42 can prevent the inner rod 18 from naturally retracting back into the quilt rod 16. When the inner rod 18 extends, the second locking block 43 moves and abuts against the limiting plate 44, thereby limiting the inner rod 18 from continuously extending outwards towards the rod 16. Therefore, the function of the first locking block 42 and the second locking block 43 is to limit the extension and retraction of the inner rod 18.

[0081] It is worth noting that since one end of the connecting rope 24 is fixed inside the inner rod 18, the relative length changes when the inner rod 18 extends. When the inner rod 18 extends, the connecting rope 24 will tilt. Therefore, the quilt rod 16 and the inner rod 18 will move upward as the inner rod 18 extends. The displacement of the quilt rod 16 and the inner rod 18 will not affect the drying function, but will only expand the drying range and increase the size of the quilts that can be dried.

[0082] When it is necessary to reset to the initial state, manually press the first locking block 42 to allow the inner rod 18 to retract into the quilt rod 16. Then press the button 17 again to disengage the connecting hook 32 from the through cavity 25. The connecting spring 22 pulls the connecting rope 24 back into the clothes rod 13, thus completing the approach of the clothes rod 13 and the quilt rod 16. When the clothes rod 13 and the quilt rod 16 are close together, the limiting hook 36 is first inserted into the through groove of the connecting plate 38 to form a hook connection. Then, the limiting block 37 limits the limiting hook 36, thus forming the connection between the clothes rod 13 and the quilt rod 16. Then, the motor in the main unit 11 drives the steel wire rope 12 to be retracted, thereby moving the clothes rod 13 and the quilt rod 16 upward back to a position near the top of the room for drying.
