Description

Technical Field

[0001] This utility model relates to the technical field of drying structures, and in particular to a windproof and anti-fall lifting hook suitable for drying racks. Background Technology

[0002] Existing clothes drying racks generally require the use of a clothes fork to lower them from a height. After clothes are clamped / hung on the rack, the same fork is needed to lift the rack back up from a lower height. This limits the use of the rack for elderly people with mobility issues or shorter individuals, resulting in significant limitations and inconvenience. Furthermore, the hooks are open, making the rack more prone to falling from its high position when there is strong wind or when clothes are lowered from nearby areas. This can cause clean clothes to get dirty again, reducing the user experience.

[0003] Therefore, based on the above-mentioned technical problems, this application proposes a windproof and anti-fall lifting hook suitable for drying racks that is highly applicable, easy to use, improves user experience, and has anti-fall function. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a windproof and anti-fall lifting hook suitable for drying racks that is highly applicable, easy to use, improves user experience, and has an anti-fall function.

[0005] To achieve the above objectives, this utility model provides a windproof and anti-fall lifting hook suitable for drying racks, comprising a hook portion, a receiving portion connected to the hook portion, a rope winding roller, and a coil spring. The side end face of the rope winding roller has a receiving cavity for coaxially embedding the coil spring, and the receiving portion has a horizontally arranged connecting pin for pivotally connecting the rope winding roller. Both ends of the coil spring are connected to the connecting pin and the rope winding roller, respectively. A hanging rope is wound around the outer circumference of the rope winding roller, and the movable end of the hanging rope hangs down to the outside of the receiving portion. A movable stop block is fixed at the movable end of the hanging rope, wherein the movable stop block moves synchronously with the hanging rope to move away from or touch the bottom of the receiving portion. The movable stop block is connected to a pre-set drying rack. By applying an external force to pull down the drying rack or the movable end of the hanging rope, the rope winding roller rotates to unwind against the elastic reaction force of the coil spring. By applying an external force to push up the drying rack or the movable end of the hanging rope, the rope winding roller rotates to rewind under the elastic force of the coil spring.

[0006] Furthermore, the inner circumferential surface of the accommodating cavity is provided with a notch extending to the outer circumferential surface of the rope winding roller. The outer end of the coil spring passes through the notch and connects to the outer circumferential surface of the rope winding roller. The outer circumferential surface of the rope winding roller is provided with a fixed locking position for the outer end of the coil spring to engage.

[0007] Furthermore, the outer circumference of the rope winding roller is provided with a rope connection port for the fixed end of the lifting rope to be fixedly connected.

[0008] Furthermore, the top of the movable contact block and the bottom of the receiving part are both equipped with magnetically attachable rope end magnets.

[0009] Furthermore, a fixed contact block is formed protruding at the bottom of the receiving part, wherein a rope end magnetic block that can be magnetically attracted is installed at the bottom of the fixed contact block and the top of the movable contact block.

[0010] Furthermore, the outer peripheral surface of the movable contact block is provided with an annular groove for mounting the drying rack.

[0011] Furthermore, a pull ring is installed at the bottom of the movable contact block.

[0012] Furthermore, the windproof and fall-proof lifting hook also includes an end cap installed on the open side of the accommodating part, the end cap having at least two primary connecting screw holes, and the accommodating part having at least two secondary connecting screw holes that cooperate with the aforementioned primary connecting screw holes.

[0013] Furthermore, the windproof and fall-proof lifting hook also includes a movable hook ring, which is pivotally connected to the hook part through a preset fixing pin. The movable hook ring is used to cooperate with the hook part to form a movable and openable sealing ring. A return torsion spring is sleeved on the fixing pin, wherein one pin of the return torsion spring is connected to the hook part and the other pin is connected to the movable hook ring.

[0014] Furthermore, the hook tip of the hook portion and the locking tongue end of the movable hook ring are both equipped with magnetically engaging hook magnets.

[0015] The present invention adopts the above-described solution, and its beneficial effects are as follows: The drying rack's raising and lowering mechanism utilizes a rope roller, spring, rope, and related components. When the user pulls down the rack / rope's movable end / ring, the rack descends rapidly. The spring's elastic reaction force gradually reduces the descent speed, eventually lowering the rack smoothly to a low position within the user's reach. This prevents injury from a rapid descent and protects the user's safety. When the user clamps clothes at a lower position and pushes the rack upward, the spring's elastic potential energy acts as an auxiliary force, assisting the user's upward push to return the rack to the clothesline at a higher position. This reduces user limitations (reducing the pushing force required, making it easier for the elderly, children, or those with hand disabilities), improving its usability and convenience. Furthermore, the magnetic attraction between the two rope ends ensures the rack is stably attached to a high position, preventing sudden falls and further enhancing safety.

[0016] By pivoting the movable hook and the hook part, the purpose of switching between closed-loop sealing and open-loop hanging can be achieved. The closed-loop structure formed can prevent the hook part from falling off the clothes rack due to wind or other factors when the drying rack is hung at a high place, thus preventing clothes from getting dirty. This improves the user experience and makes the hanging effect more stable and reliable. Attached Figure Description

Detailed Implementation

[0035] To facilitate understanding of this utility model, a more complete description is provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0036] See appendix Figure 1-17As shown, in this embodiment, a windproof and anti-fall lifting hook suitable for drying racks is provided. This windproof and anti-fall lifting hook is attached to a clothes rack and includes a hook portion 11, a receiving portion 12 connected to the hook portion 11, a rope roller 2, and a coil spring 3. The hook portion 11 ensures that the windproof and anti-fall lifting hook of this embodiment can be attached to a clothes rack / drying rod, etc. The receiving portion 12 ensures that it provides space for the rope roller 2 and related lifting components. Furthermore, the hook portion 11 is positioned above the receiving portion 12. The winding roller 2 has a cavity on its side end face for the coaxial mounting of the coil spring 3, and a horizontally arranged connecting pin 91 for pivotally connecting the winding roller 2 is provided in the cavity 12; the two ends of the coil spring 3 are respectively connected to the connecting pin 91 and the winding roller 2; a hanging rope 4 is wound around the outer circumference of the winding roller 2 (the specific length of the hanging rope 4 can be selected according to the preset specifications or changed according to the actual situation), the movable end of the hanging rope 4 hangs down and extends out of the cavity 12, and a movable stop block 6 is fixed at the movable end of the hanging rope 4. The movable stop block 6 is connected to the preset drying rack 5, wherein the movable end of the hanging rope 4 hangs down and extends out of the cavity 12, and a movable stop block 6 is fixed at the movable end of the hanging rope 4. The movable stop block 6 is connected to the preset drying rack 5. The movable stop block 6 moves synchronously with the lifting rope 4 to move away from or touch the bottom of the receiving part 12. By setting the movable stop block 6, when the rope winding wheel 2 rotates and winds to a preset degree (i.e., when the top of the movable stop block 6 contacts the bottom of the receiving part 12), the top of the movable stop block 6 stops and abuts against the bottom of the receiving part 12, thereby limiting the rotation and winding of the rope winding wheel 2. This relatively avoids the lifting rope 4 from becoming too tight due to excessive rotation and winding of the rope winding wheel 2, which could damage other parts and reduce subsequent maintenance costs. Furthermore, both the top of the movable stop block 6 and the bottom of the receiving part 12 are equipped with... Equipped with a magnetically engaging rope end magnet 7, when the top of the movable contact block 6 contacts the bottom of the receiving part 12, the two magnetically engage to keep the drying rack 5 stably in a high position and the hanging rope 4 wound around the outer circumference of the rope winding roller 2 is not in a taut state, and the coil spring 3 is not in a compressed state (due to the traction of the hanging rope 4). This relatively avoids continuous traction on the hanging rope 4 and the coil spring 3 (if the hanging rope 4 is under continuous traction for a long time, its service life will be relatively reduced; similarly, if the coil spring 3 is in a compressed / energy-storing state for a long time, its aging will be accelerated), thus relatively reducing maintenance costs. By applying an external force to pull down the movable end of the drying rack 5 or the hanging rope 4, the rope winding roller 2 overcomes the elastic reaction force of the coil spring 3 to rotate and unwind; by applying an external force to push up the movable end of the drying rack 5 or the hanging rope 4, the rope winding roller 2 is driven by the elastic force of the coil spring 3 to rotate and wind up.

[0037] Specifically, when the rope roller 2 rotates to unwind, the coil spring 3 is in an energy storage state. As the drying rack 5 descends, the force required for the coil spring 3 to further store energy increases, thus offsetting some of the potential energy generated by the descent of the drying rack 5 (demonstrating its buffering effect). This results in the drying rack 5 descending rapidly first, then gradually slowing down, and finally stopping smoothly. This also prevents the drying rack 5 from falling too quickly or suddenly and injuring the user. Conversely, when an external force is applied to push the drying rack 5 or the movable end of the hanging rope 4 (the user uses a clothes fork or other tools to push upwards), the coil spring 3 is in a release state (that is, the coil spring 3 releases the elastic potential energy collected when the drying rack 5 descends as auxiliary power). This, combined with the user's upward pushing action, drives the rope roller 2 to rotate and rewind, causing the drying rack 5 to gradually rise. This relatively reduces the force required for the user to push the drying rack 5 (the drying rack 5 increases in weight after clothes are clamped, thus increasing the force required for the drying rack 5 to rise), increasing the convenience for the user (beneficial for the elderly, children, or people with limited hand strength).

[0038] See appendix Figure 8 , 9 As shown in Figures 12 and 13, furthermore, a notch 21 is provided on the inner circumferential surface of the accommodating cavity, extending to the outer circumferential surface of the rope winding roller 2. The outer end of the coil spring 3 passes through the notch and connects to the outer circumferential surface of the rope winding roller 2. The outer circumferential surface of the rope winding roller 2 is provided with a fixed locking position 22 for engaging the outer end of the coil spring 3. Specifically, the outer end of the coil spring 3 includes a narrow neck section and a wide head section (not shown in the figure). When the outer end of the coil spring 3 passes through the notch 21 to reach the outer circumferential surface of the rope winding roller 2, and then passes through the fixed locking position 22 to reach the inner circumferential surface of the rope winding roller 2, the wide head section is located on the inner circumferential surface of the rope winding roller 2, and the narrow neck section is located on the fixed locking position 22. As the rope winding roller 2 winds up... Alternatively, the wide end section can be engaged with the fixed locking position 22 (i.e., it can be movably engaged within the fixed locking position 22), allowing the coil spring 3 to cooperate with the rope winding roller 2 to achieve unwinding energy storage (to buffer the descent speed of the drying rack 5) and rewinding energy release (to provide auxiliary power to pull the drying rack 5 upwards), ensuring the effectiveness of the windproof and anti-fall lifting hook; in addition, the outer circumference of the rope winding roller 2 is provided with a rope receiving port 24 for the fixed end of the hanging rope 4 to be fixedly connected, so that after the fixed end of the hanging rope 4 passes through the rope receiving port 24, the fixed end of the hanging rope 4 is knotted, thereby achieving an effective and stable connection between the fixed end of the hanging rope 4 and the rope winding roller 2, ensuring that the hanging rope 4 can be unwound or rewound accordingly with the rotation of the rope winding roller 2.

[0039] See appendix Figure 5 , 13As shown, further, a pin hole 23 is provided at the center of the winding roller 2 for the connecting pin 91 to pass through. By providing the pin hole 23, a fixing hole 121 is provided at the center of the inner side of the receiving part 12 for the end of the connecting pin 91 to be placed and positioned (the fixing hole 121 can be set to be through or not through according to actual needs). After the connecting pin 91 passes through the pin hole 23 and the fixing hole 121, the winding roller 2 and the receiving part 12 are rotated and engaged, realizing the unwinding or winding function of the winding roller 2.

[0040] See appendix Figure 1-5 As shown, the bottom of the receiving part 12 is further formed with a fixed stop block 122. The bottom of the fixed stop block 122 and the top of the movable stop block 6 are both equipped with magnetically engaging rope end magnets 7. The fixed stop block 122 can better stop and cooperate with the movable stop block 6 (because the arc-shaped structure at the bottom of the receiving part 12 in this embodiment cannot fit well with the plane at the top of the movable stop block 6, it may wobble during use, thus affecting the stability of the hanging. Therefore, a fixed stop block 122 is set at the bottom of the receiving part 12 so that the fixed stop block 122 and the movable stop block 6 fit horizontally, which can ensure the stability of the hanging); and both rope end magnets 7 are ring structures (the ring arrangement of the rope end magnets 7 allows the movable end of the suspension rope 4 to pass through the two rope end magnets 7 without affecting their normal movement).

[0041] Furthermore, a pull ring 8 is installed at the bottom of the movable contact block 6. By setting the pull ring 8, an additional position can be provided for the user to pull the movable end of the drying rack 5 or the hanging rope 4, improving the user's usability and convenience. Moreover, compared to having the user directly pull down the movable end of the drying rack 5 or the hanging rope 4, the ring-shaped pull ring 8 makes it easier for the user (by using a clothes fork or direct contact) to pull down the hanging rope 4, thereby improving the user's experience and convenience, and realizing the lowering function of the windproof and anti-fall lifting hook. Secondly, in this embodiment, the pull ring 8 is preferably a closed ring rope (other components that are easy for the user to pull down can be selected according to the actual situation).

[0042] See appendix Figure 3 As shown, further, a through-hole 1221 is provided on the fixed contact block 122. The 1221 is used for the movable end of the hanging rope 4 to pass through. By setting the 1221, a position is provided for the movable end of the hanging rope 4 to pass through (that is, the movable end of the hanging rope 4 can reciprocate through the 1221), so as to cooperate with the lifting and lowering of the drying rack 5 and the winding and unwinding functions of the hanging rope 4. Secondly, a rope end fixing hole 61 is provided on the movable contact block 6, which extends vertically and is used for the movable end of the hanging rope 4 to pass through and fix. In addition, a radially penetrating safety ring hole 62 is provided at the bottom of the movable contact block 6 and communicates with the rope end fixing hole 61. The safety ring hole 62 is used for the installation of the pull ring 8.

[0043] It should be noted that after the movable end of the suspension rope 4 passes through the rope end fixing hole 61 and reaches the junction of the rope end fixing hole 61 and the safety ring hole 62, the movable end of the suspension rope 4 can be fixed at that position by high temperature or the movable end of the suspension rope 4 can be knotted to make it engage with the junction position (both methods are to make the diameter of the movable end of the suspension rope 4 larger than the inner diameter of the rope end fixing hole 61), thereby achieving an effective and stable connection between the movable end of the suspension rope 4 and the movable contact block 6.

[0044] See appendix Figure 4 , 6 As shown in Figures 15, 16, and 17, furthermore, an annular groove 63 is provided on the outer circumferential surface of the movable contact block 6 for mounting the drying rack 5. By mounting the drying rack 5 through the annular groove 63, it can accommodate drying racks 5 of different specifications, improving the adaptability of this windproof and anti-fall lifting hook. The specific installation steps for the movable contact block 6 and the drying rack 5 are as follows: connect the drying rack 5 to the pre-set snap-fit ​​component using a connecting rope, and then snap the snap-fit ​​component onto the annular groove 63, so that the drying rack 5 can rise and fall with the movement of the movable contact block 6 (see reference for specific installation effect). Figure 4 ).

[0045] Furthermore, the bottom end of the fixed contact block 122 is provided with a primary magnetic block mounting hole 1222 for mounting the corresponding rope end magnetic block 7, and the top of the movable contact block 6 is provided with a secondary magnetic block mounting hole 64 for mounting the corresponding rope end magnetic block 7 (the above magnetic block mounting holes and the corresponding rope end magnetic blocks 7 can be fixed by adhesive). Through the magnetic attraction between the two rope end magnetic blocks 7, the phenomenon of sudden drop of the drying rack 5 can be avoided (the cause may be: the elastic reaction force of the coil spring 3 is reduced due to damage / aging). This ensures the working stability of the windproof and anti-fall lifting hook in this embodiment, and keeps it stably connected to the drying rack under normal conditions. At the same time, it can prevent the phenomenon of the coil spring 3 being compressed for a long time due to the continuous traction (pulling down) of the movable end of the hanging rope 4 by the gravitational potential energy of the drying rack 5 (which is prone to aging), thus extending the service life of the coil spring 3 and reducing maintenance costs.

[0046] Specifically, when the user pulls the pull ring 8 / drying rack 5 downwards using the clothes fork (the rope reel roller 2 can only unwind when the user's pulling force is greater than the attraction force between the two rope end magnets 7), the elastic reaction force of the coil spring 3 gradually reduces the descent speed of the drying rack 5 (that is, when the drying rack 5 descends, the elastic potential energy of the coil spring 3 stores energy as the drying rack 5 descends, allowing the elastic potential energy to interact with the gravitational potential energy, thereby gradually slowing down the descent speed of the drying rack 5, preventing the drying rack 5 from falling too fast and injuring the user, and improving the user's safety), until the drying rack 5 on the movable end of the hanging rope 4 falls to a height that the user can directly contact. (The specific low position of the drying rack 5 / the height at which the user can directly access it can be set by adjusting the length of the hanging rope 4); After the user has finished clamping the clothes, the user pushes the drying rack 5 / the movable end of the hanging rope 4 upwards with the clothes fork, and through the elastic tendency of the coil spring 3 (as an auxiliary power to cooperate with the user's pushing force), the rope winding roller 2 is driven to rewind, so that the hanging rope 4 is rewound on the outer circumference of the rope winding roller 2, realizing the upward reset of the drying rack 5, until the top of the movable block 6 and the bottom of the fixed block 122 stop and abut, so that the two rope end magnets 7 are magnetically attracted to each other, thereby making the drying rack 5 stably hung on the clothesline at a high place.

[0047] See appendix Figure 5 , 10 As shown, the windproof and fall-proof lifting hook further includes an end cap 9 installed on the open side of the receiving part 12. The end cap 9 has at least two, preferably four, annularly arranged primary connecting screw holes 92. The receiving part 12 has at least two, preferably four, annularly arranged secondary connecting screw holes 123 that cooperate with the primary connecting screw holes 92 (the connecting screw holes can be connected by preset screws). By setting the end cap 9, the components such as the rope winding roller 2 and the coil spring 3 inside the receiving part 12 are sealed, reducing the impact of external factors on the normal operation of the above components (which may cause coil springs to malfunction). 3. Corrosion, aging, and the winding roller 2 or coil spring 3 may experience rotational jamming. Among these, the jamming may be caused by particulate matter from the outside or generated during operation that obstructs its rotation. This extends its service life and reduces maintenance costs. Secondly, the connection between the primary connecting screw hole 92 and the secondary connecting screw hole 123 allows for a detachable sealing structure between the accommodating part 12 and the end cover 9. This makes it easier to disassemble the device when problems arise during subsequent use or during routine maintenance, avoiding the need to replace the entire device. After maintenance, the device can be reinstalled to achieve a seal, thereby reducing maintenance costs.

[0048] It should be noted that a connecting pin 91 for positioning the coil spring 3 is integrally formed at the center of the inner side of the end cap 9. The connecting pin 91 has a radially penetrating through groove 911, which divides the connecting pin 91 into a symmetrically arranged primary pin 912 and a secondary pin 913. The inner end of the coil spring 3 is bent twice to form a primary fixing part 31 and a secondary fixing part 32. By inserting the primary pin 912 into the primary fixing part 31 and the secondary pin 913 into the secondary fixing part 32, the inner end of the coil spring 3 can be stably connected to the connecting pin 91 as the coiling roller 2 rotates in the forward or reverse direction (ensuring that the inner end of the coil spring 3 serves as a fixing point).

[0049] See appendix Figure 1-5 As shown, in this embodiment, the windproof and anti-fall lifting hook also includes a movable hook ring 111, wherein the movable hook ring 111 has an S-shaped structure; the movable hook ring 111 is pivotally connected to the hook part 11 through a preset fixing pin, and the movable hook ring 111 is used to cooperate with the hook part 11 to form a movable and openable sealing ring; by setting a resettable movable hook ring 111 (when hooked to the clothesline, force is applied to push the movable hook ring 111 to open the ring; after hooking is completed, the external force is removed to reset the ring to close), it is ensured that the windproof and anti-fall lifting hook in this embodiment can be stably hooked to the clothesline / clothes drying rack. The pole (demonstrating its windproof, anti-fall, and anti-detachment functions) prevents the windproof and anti-fall lifting hook from falling off the clothes rack / drying rod due to external forces (such as wind), thus affecting the user experience. A reset torsion spring 112 is fitted on the fixing pin. One pin of the reset torsion spring 112 is connected to the hook part 11, and the other pin is connected to the movable hook ring 111. Through the reset torsion spring 112, the movable hook ring 111 stores energy when it is pushed by an external force to rotate open, and releases energy when the external force is removed, driving the reset closed loop of the movable hook ring 111, thus improving the user experience.

[0050] Secondly, both the hook tip of the hook part 11 and the locking tongue end 1112 of the movable hook ring 111 are equipped with magnetically engaging hook magnets 113. Through the magnetic attraction between the two hook magnets 113, the connection stability between the movable hook ring 111 and the hook part 11 and the sealing effectiveness of the sealing ring formed by the two can be further improved. This avoids the locking tongue end 1112 of the movable hook ring 111 not moving completely to the hook tip of the hook part 11 when resetting due to the aging of the reset torsion spring 112, thereby ensuring the stable attachment of the windproof and fall-proof lifting hook.

[0051] Its specific working process is as follows: by pushing the handle end 1111 of the movable hook 111 upwards ( Figure 1Rotate (as indicated by the arrow) to make the movable hook 111 rotate around its pivot position with the hook part 11, so that the locking tongue end 1112 of the movable hook 111 moves away from the hook tip of the hook part 11, thus opening the loop; after the hook part 11 is hooked onto the clothes rack / clothes drying rack, by the elastic tendency of the return torsion spring 112, the movable hook 111 rotates in the opposite direction around its pivot position with the hook part 11, so that the locking tongue end 1112 of the movable hook 111 moves closer to the hook tip of the hook part 11, thus closing the loop.

[0052] It should be noted that the existing drying rack 5 generally requires the use of a clothes fork to lower it from the high clothes rack. After clamping / hanging the clothes onto the drying rack 5, the clothes fork is also needed to lower the drying rack 5 from the low position back onto the high clothes rack. This poses a limitation for some elderly people with mobility difficulties or shorter people, and has the disadvantages of being highly restricted and inconvenient to use.

[0053] In this embodiment, the drying rack 5 is raised and lowered by setting up a rope roller 2, a coil spring 3, a hanging rope 4, and related components. When the hook part 11 is hooked onto the preset clothes rack, the user can pull the movable end / pull ring 8 of the drying rack 5 / hanging rope 4 with the help of tools such as a clothes fork. Figure 7 (Pull in the direction indicated by the arrow), where the traction force must be greater than (overcome) the elastic reaction force of the coil spring 3 and the attraction force between the two rope end magnets 7 (the purpose of the elastic reaction force of the coil spring 3 and this attraction force is to ensure that the drying rack 5 can be stably positioned at a high position without sudden drop). When the above traction force is greater than the elastic reaction force of the coil spring and the attraction force between the two rope end magnets 7, the two rope end magnets 7 separate, causing the drying rack 5 to descend. At the same time, under the elastic reaction force of the coil spring 3 (the coil spring 3 stores energy for buffering), the drying rack 5 moves downward from the clothes rack at a high position as the rope roller 2 unwinds, in a state of first fast and then slow. After clamping / hanging the clothes onto the drying rack 5, the user pushes the drying rack 5 up using the clothes fork. The movable end of the hanging rope 4, under the elastic force of the coil spring 3, drives the rope roller 2 to rewind (the elastic force of the coil spring 3 acts as an auxiliary force to assist the user's upward pushing action), so that the user does not need to use excessive pushing force to send the drying rack 5 from a low position back to the clothes rack at a high position, reducing its usage threshold / limitations and improving its applicability and convenience; secondly, through the pivotal engagement between the movable hook ring 111 and the hook part 11, closed-loop sealing and open-loop hooking can be achieved according to the user's corresponding actions, preventing the drying rack 5 from getting dirty due to the hook part 11 falling off the clothes rack when it is hung at a high position, improving the user experience, and ensuring the effectiveness of the windproof and anti-fall lifting hook in this embodiment.
