Description

Technical Field

[0001] This utility model belongs to the field of clothes drying racks, and more specifically, it relates to a steel wire rope gravity protection and anti-tangling device. Background Technology

[0002] Clothes drying racks, as a new generation of drying furniture products, are being used more and more widely.

[0003] Most existing clothes drying racks are equipped with a lift function, which provides convenience for users but also poses some safety hazards.

[0004] For example, Chinese invention patent publication number "CN119270723A" discloses "a control method, system, clothes drying rack, storage medium, and program product for a clothes drying rack, relating to the technical field of clothes drying racks. The control method for the clothes drying rack includes: acquiring a first distance measured by a distance measuring device; the distance measuring device is installed at the bottom of the main unit and / or the drying rod assembly of the clothes drying rack; the first distance includes the distance between the distance measuring device and an object located below the distance measuring device; based on the current state of the drying rod assembly and the first distance, controlling the drying rod assembly to perform corresponding operations. The embodiments of this application can realize the automatic control of the clothes drying rack in different application scenarios, simplifying operation and making the control process more convenient."

[0005] In the aforementioned prior art, during the lifting function of a clothes drying rack, within the brief delay after the user lifts the drying rod and triggers the motor drive, the steel wire rope on the lifted side loses tension and sags instantly. This easily becomes entangled in adjacent components such as the scissor frame and guide wheels, leading to jamming, deformation, or even breakage. Therefore, a gravity protection and anti-entanglement device for the steel wire rope is provided. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a steel wire rope gravity protection and anti-winding device, which can prevent the steel wire rope from getting stuck in other parts and causing jamming by gravity.

[0007] This utility model discloses a steel wire rope gravity protection and anti-entanglement device, comprising:

[0008] The main unit is installed on the indoor ceiling and has an electric drive assembly inside. The electric drive assembly has retractable steel wire ropes that extend downwards from both ends of the main unit.

[0009] The drying section is located below the main unit, and a first fixing member is installed on the pole base, with the top of the first fixing member extending outside the pole base;

[0010] The drop assembly is installed in a free state at the bottom end of the wire rope and contains a weight-adding component; a second fixing component is installed inside the drop assembly, and the second fixing component extends upward to the top of the drop assembly.

[0011] The steel wire rope passes through the first fixing member, and its bottom end is installed with the second fixing member.

[0012] As a further improvement of this utility model, the pendant assembly further includes a main shell and a secondary shell, which are installed and fixed to each other to enclose an internal cavity;

[0013] The outer surfaces of the main housing and the secondary housing are smooth.

[0014] As a further improvement of this utility model, connecting columns are arranged diagonally on the inner walls of the main housing and the sub-housing, and the main housing and the sub-housing are arranged opposite to each other and are installed by corresponding insertion of the connecting columns on their respective inner walls.

[0015] As a further improvement of this utility model, the weight-adding component includes a weight block, the second fixing component is installed on the weight block, and the top of the second fixing component penetrates the sub-shell and extends upward;

[0016] The weight is made of metal.

[0017] As a further improvement of this utility model, a raised step structure is provided on the end face of the weight, and the bottom of the second fixing member abuts against the step structure.

[0018] As a further improvement of this utility model, the two opposite corners of the weight are recessed with inner arc surfaces, and the two inner arc surfaces are respectively abutted against the outer surface of the connecting column at opposite positions.

[0019] As a further improvement of this utility model, the top of the sub-shell is provided with a mounting groove, and the second fixing member passes through the mounting groove and extends upward.

[0020] As a further improvement of this utility model, the first fixing member includes a main rope frame, which is installed on the side wall of the pole seat. The top of the main rope frame is provided with a horizontally bent flap, which extends to the outside of the pole seat.

[0021] As a further improvement of this utility model, the main rope frame is provided with a first hole through which the wire rope can pass, and the first hole extends upward to the folding piece;

[0022] The second fixing member is provided with a second hole for the installation of the wire rope.

[0023] As a further improvement of this utility model, the rod seat is provided with a notch, and the folding piece can extend out of the rod seat along the notch;

[0024] The length of the flap is greater than the length of the notch, and the flap is abutted against the outer surface of the rod base.

[0025] Compared with existing technologies, the advantages of this utility model are:

[0026] (1) This solution is equipped with a drop assembly with a built-in high-density metal weight. When the user lightly lifts the drying pole to trigger the upward command, the freely suspended weight applies a continuous downward force to the end of the wire rope, forcibly maintaining the wire rope in a taut state throughout the process. This completely eliminates the "S"-shaped bend caused by the instantaneous slack and drooping of the wire rope in the traditional solution, and fundamentally eliminates the risk of the wire rope getting tangled in the scissor frame and guide wheel.

[0027] (2) The main / sub-shell of the drop assembly in this scheme is made of ultra-smooth PC material, with a dynamic friction coefficient of ≤0.15 with the side wall of the pole seat, ensuring that the drop assembly can slide freely along the pole seat when the pole is tilted, and avoiding the failure of the gravity-pull steel wire rope due to the influence of friction.

[0041] 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.

[0042] For specific implementation examples, please refer to: Figure 1-11 A steel wire rope gravity protection and anti-entanglement device includes:

[0043] The main unit 11 is installed on the indoor ceiling and has an electric drive assembly inside. The electric drive assembly has a retractable steel wire rope 13, which extends downward from both ends of the main unit 11.

[0044] It is understood that the electric drive assembly includes conventional mechanisms such as a motor and a winding reel found in clothes drying machines. The rotation of the motor drives the winding reel to rotate, thereby winding and unwinding the steel wire rope 13. At the same time, guide wheels are provided at both ends inside the main unit 11, and the steel wire rope 13 extends downwards from the main unit 11 under the guidance of the guide wheels.

[0045] The drying section is located below the main unit 11. A first fixing member is installed on the pole base 14, and the top of the first fixing member extends outside the pole base 14.

[0046] like Figure 1As shown, the drying assembly includes a pole base 14 and drying rods 15. The drying rods 15 are equipped with hanging holes and other structures for hanging and drying clothes. The pole base 14 is a connecting structure used to connect the two drying rods 15 and the steel wire rope 13. A scissor frame 12 is also connected between the main unit 11 and the pole base 14. The scissor frame 12 can fold vertically according to the distance between the main unit 11 and the pole base 14, thereby increasing the stability of the drying assembly's lifting and lowering.

[0047] The drop assembly 200 is installed in a free state at the bottom end of the wire rope 13 and has a weight-adding component inside; a second fixing component is installed inside the drop assembly 200 and extends upward to the top of the drop assembly 200.

[0048] It is understandable that the aforementioned drop assembly 200 is installed in a free state at the bottom of the wire rope 13. Therefore, due to the downward shift of the center of gravity, the wire rope 13 will always remain taut due to the weight of the added weight.

[0049] It is worth further explanation that, such as Figure 3-4 As shown, the hanging part assembly 200 is in a free state. Therefore, when the entire drying part assembly tilts to one or both sides along its length, the hanging part assembly 200 will not be affected by the drying part assembly and will always keep the steel wire rope 13 taut and straight. This prevents the steel wire rope 13 from being in a free state due to relaxation and getting stuck in other parts of the clothes drying machine.

[0050] Scenario description: such as Figure 3-4 As shown, the tilting of one or both sides of the drying section along its length is specifically reflected in the user's use of the clothes dryer's lifting function.

[0051] The clothes drying rack's lift-up function works by triggering a lifting command through physical movement. Users simply lift the drying rod (or a specific component), and the sensor in the clothes drying rack controls the motor to start, thus automatically lifting the drying rod to the top without the need for a remote control or APP operation.

[0052] The steel wire rope 13 passes through the first fixing member, and its bottom end is installed with the second fixing member.

[0053] It is worth noting that the bottom of the wire rope 13 is also provided with a plug 35 to prevent the wire rope 13 from coming out in reverse. The first fixing member includes a main rope frame 31, and the second fixing member includes a secondary rope frame 24. After the wire rope 13 passes through the main rope frame 31, it passes through the secondary rope frame 24 again, and the plug 35 is installed and fixed to the secondary rope frame 24.

[0054] The pendant assembly 200 further includes a main housing 21 and a secondary housing 23, which are installed and fixed to each other to form an internal cavity; the outer surfaces of the main housing 21 and the secondary housing 23 are smooth. The top of the secondary housing 23 is provided with a mounting groove 25, and the second fixing member passes through the mounting groove 25 and extends upward.

[0055] Connecting posts 26 are arranged diagonally on the inner walls of the main housing 21 and the sub-housing 23, and the main housing 21 and the sub-housing 23 are arranged opposite to each other and are installed by corresponding insertion of the connecting posts 26 on their respective inner walls.

[0056] It is understood that the main housing 21 and the secondary housing 23 have the same structure, both having smooth outer surfaces and mounting structures on their inner walls. The main housing 21 and the secondary housing 23 are injection molded, resulting in smooth surfaces (e.g., injection molded from PC material), allowing them to slide together at the side end of the rod base 14. This design reduces friction through the smooth outer surface, ensuring that the free state of the drop assembly 200 is not disturbed by friction.

[0057] It should be further explained that the connecting post 26 is a conventional shell mounting structure, arranged in a column shape and integrally formed with the main shell 21 and the sub-shell 23 during production. Therefore, when installing the main shell 21 and the sub-shell 23, it is only necessary to align the connecting posts 26 on both and forcefully insert them to complete the installation of the main shell 21 and the sub-shell 23. In this embodiment, the installation of the main shell 21 and the sub-shell 23 is used to install, fix, and store the weight-adding component and the secondary rope frame 24.

[0058] It should be further explained that the difference between the main housing 21 and the secondary housing 23 is that the secondary housing 23 is provided with a vertically penetrating mounting groove 25 at its top, and the top of the secondary rope frame 24 can extend from the mounting groove 25 to the top of the secondary housing 23.

[0059] The weight-adding component includes a weight block 22, and the second fixing member is installed on the weight block 22. The top of the second fixing member penetrates the sub-shell 23 and extends upward. The weight block 22 is made of metal material.

[0060] The end face of the weight 22 is provided with a raised step structure, and the bottom of the second fixing member is abutted against the step structure.

[0061] It is understandable that the aforementioned weight 22 is made of metal materials for counterweight and weight increase, preferably metals with a high specific gravity such as cast iron and lead.

[0062] It is worth noting that the aforementioned weight 22 has a recessed fastening groove 27, and the bottom of the auxiliary rope frame 24 is also provided with a bent hook 29. The hook 29 extends into the fastening groove 27 to form a connection between the weight 22 and the auxiliary rope frame 24. At the same time, the weight 22 is also provided with a stepped structure, which includes a boss 28. The boss 28 abuts against the hook 29, thereby providing support for the auxiliary rope frame 24. The top of the auxiliary rope frame 24 extends above the auxiliary housing 23 through the mounting groove 25.

[0063] The weight 22 has two concave inner arc surfaces 30 at opposite corners, and the two inner arc surfaces 30 respectively abut against the outer surface of the connecting column 26 at opposite positions.

[0064] It is understandable that the two inner arc surfaces 30 provided on the aforementioned weight block 22 are concave structures that allow the connecting post 26 to pass. At the same time, the inner arc surfaces 30 and the connecting post 26 are abutted together, so the two connecting posts 26 can play a limiting role in the weight block 22.

[0065] The first fixing member includes a main rope frame 31, which is installed on the side wall of the pole base 14. The top of the main rope frame 31 is provided with a horizontally bent flap 17, which extends to the outside of the pole base 14.

[0066] The main rope frame 31 is provided with a first hole through which the wire rope 13 can pass, and the first hole extends upward to the flap 17; the second fixing member is provided with a second hole for the installation of the wire rope 13.

[0067] It is understandable that, such as Figure 5 As shown, both the main rope frame 31 and the auxiliary rope frame 24 have horizontally bent portions at their tops. These horizontally bent portions are used for connecting the steel wire rope 13 in its vertical state and for connecting with the plug 35. The first hole includes a main rope hole 33, and the second hole includes an auxiliary rope hole 36. Both the main rope hole 33 and the auxiliary rope hole 36 have a through hole at their bottom for the plug 35 to enter and exit. The top of the through hole extends upward into a slender groove-like structure to limit the plug 35. The top of the slender groove-like structure extends horizontally in sync with the bending of the main rope frame 31 and the auxiliary rope frame 24.

[0068] It is worth noting that, such as Figure 7 As shown, the main rope frame 31 is installed and fixed to the side wall of the pole seat 14, and a pin 34 is provided inside the pole seat 14. The main rope frame 31 is provided with a mounting hole 32. The pin 34 passes through the pole seat 14 and the mounting hole 32 to install and fix the main rope frame 31 and the pole seat 14.

[0069] The rod base 14 is provided with a notch 16, and the flap 17 can extend out of the rod base 14 along the notch 16; the length of the flap 17 is greater than the length of the notch 16, and the flap 17 is abutted against the outer surface of the rod base 14.

[0070] It is understandable that the notch 16 on the pole seat 14 is used to accommodate the top bend of the main rope frame 31, while the flap 17 extends out of the pole seat 14 and the length of the flap 17 is greater than the length of the notch 16. Therefore, the contact between the flap 17 and the notch 16 can improve the installation stability of the main rope frame 31.

[0071] Instructions for Use: When using the lift function of the clothes drying rack, the user typically lifts one side of the pole 14 or one side of the folding plate 17 to tilt the drying section. This triggers the lift function, automatically pulling the steel wire rope 13 to lift the drying section. However, the problem is that during the time between the user's lifting action and the motor's activation, the lifted steel wire rope 13 is in a free state, causing it to bend and deform. This makes it easy for the steel wire rope 13 to get stuck or entangled in other parts of the clothes drying rack, such as the scissor bracket 12 and other components within the main unit 11, leading to jamming or damage. Therefore, this embodiment provides a gravity protection and anti-entanglement mechanism for the steel wire rope 13. At the moment of lifting, the free-state hanging section 200 remains downward under its own weight, keeping the steel wire rope 13 taut and preventing it from becoming free. This effectively protects the steel wire rope 13 and prevents it from jamming or entangled.

[0072] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within this application. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, it is clear that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. Multiple units or devices recited in the apparatus claims may also be implemented by a single unit or device in software or hardware. The terms "first," "second," etc., are used to indicate names and do not indicate any particular order.
