Description

Technical Field

[0001] This application relates to the technical field of clothes drying equipment, and more particularly to a suspension assembly and clothes drying rack. Background Technology

[0002] Existing electric clothes drying racks typically consist of two parts: a main unit and a clothes rack for drying clothes. The main unit, as the core driving component, integrates a power system and transmission mechanism. Specifically, the main unit generally contains two independent steel wire rope transmission assemblies driven by a drive motor. These two steel wire ropes hang down from the left and right ends or front and rear ends of the main unit housing and are fixedly connected to the corresponding ends of the clothes rack. When the user initiates the lifting command, the motor synchronously drives the two steel wire ropes to wind or release them through a reduction gearbox and other transmission structures, thereby realizing the electric lifting operation of the clothes rack and completing the function of drying or collecting clothes.

[0003] However, in actual production, assembly, and long-term use, the above structure is prone to the problem of inconsistent heights at both ends of the clothes rack. The specific reasons are as follows: Assembly and component precision errors: During the production assembly stage, due to limitations in processing technology, there may be slight deviations in the length and diameter of the two sets of wire ropes. At the same time, insufficient installation precision of components such as guide wheels and reels used to fix the wire ropes inside the main unit, or differences in frictional resistance of rotating components such as bearings, will cause uneven force on the two sets of wire ropes during the hanging process, which will ultimately result in different hanging lengths at the two ends of the clothes rack, forming a height difference.

[0004] Differences in tension deformation after long-term use: In daily use, electric clothes drying racks frequently bear the load of clothing weight, and the steel wire ropes repeatedly experience tensile and bending stresses during winding and unwinding. Due to potential differences in the distribution of stress points between the two sets of steel wire ropes, their elastic deformation or plastic deformation will gradually deviate after long-term use, further leading to differences in the actual effective lengths of the two sets of steel wire ropes, ultimately causing an imbalance in the height of the two ends of the clothes drying rack.

[0005] This inconsistency in height not only affects the aesthetics of the clothes drying rack, but also leads to uneven drying of clothes. It may even exacerbate the wear and tear on the main components due to long-term uneven stress, reducing the service life of the equipment. Therefore, there is an urgent need for a technical solution to solve the above problems. Utility Model Content

[0014] Optionally, an upper retaining ring is provided on the top side of the inner support portion. The diameter of the upper retaining ring is larger than the diameter of the wire rope and smaller than the diameter of the rope end, so that the rope end can push the inner support portion upward through the upper retaining ring and enter the wire clamping groove.

[0015] Optionally, the card slot includes an upper card slot area and a lower card slot area, which are arranged vertically. The width of the lower card slot area is greater than the width of the upper card slot area.

The inner support portion is restricted to below the upper card slot area.

[0016] Optionally, the locking member includes a connecting body, an inner support portion, and a clamping portion. The inner support portion and the clamping portion are respectively connected to the upper and lower sides of the connecting body.

The clamping portion can clamp the rope end.

[0017] Optionally, the locking member is provided with an insertion groove that passes through the inner support, the connecting body, and the clamping part, and the wire rope can be inserted into the locking member through the insertion groove.

[0018] Optionally, the adjusting member is rotatably mounted on the fixed frame.

The cable holder is located between the first horizontal plate and the second horizontal plate.

[0020] Optionally, the fixing frame further includes at least one side vertical plate vertically connected to the main vertical plate, and the wire fixing frame is slidably connected to the side vertical plate, guiding the vertical movement of the wire fixing frame through the side vertical plate.

[0022] The beneficial effects of this application are as follows: Based on the suspension component provided by this utility model, the mechanical adjustment structure can specifically compensate for errors in the length or deformation of the steel wire rope, solving the problem of inconsistent heights at both ends of the clothes rack, ensuring even drying of clothes, and preventing clothes from slipping or drying unevenly due to tilting.

[0026] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] Existing electric clothes drying racks typically consist of two parts: a main unit and a clothes rack for drying clothes. The main unit, as the core driving component, integrates a power system and transmission mechanism. Specifically, the main unit generally contains two independent steel wire rope transmission assemblies driven by a drive motor. These two steel wire ropes hang down from the left and right ends or front and rear ends of the main unit housing and are fixedly connected to the corresponding ends of the clothes rack. When the user initiates the lifting command, the motor synchronously drives the two steel wire ropes to wind or release them through a reduction gearbox and other transmission structures, thereby realizing the electric lifting operation of the clothes rack and completing the function of drying or collecting clothes.

[0030] However, in actual production, assembly, and long-term use, the above structure is prone to the problem of inconsistent heights at both ends of the clothes rack. The specific reasons are as follows: Assembly and component precision errors: During the production assembly stage, due to limitations in processing technology, there may be slight deviations in the length and diameter of the two sets of wire ropes. At the same time, insufficient installation precision of components such as guide wheels and reels used to fix the wire ropes inside the main unit, or differences in frictional resistance of rotating components such as bearings, will cause uneven force on the two sets of wire ropes during the hanging process, which will ultimately result in different hanging lengths at the two ends of the clothes rack, forming a height difference.

[0031] Differences in tension deformation after long-term use: In daily use, electric clothes drying racks frequently bear the load of clothing weight, and the steel wire ropes repeatedly experience tensile and bending stresses during winding and unwinding. Due to potential differences in the distribution of stress points between the two sets of steel wire ropes, their elastic deformation or plastic deformation will gradually deviate after long-term use, further leading to differences in the actual effective lengths of the two sets of steel wire ropes, ultimately causing an imbalance in the height of the two ends of the clothes drying rack.

[0032] This inconsistency in height not only affects the aesthetics of the clothes drying rack, but also leads to uneven drying of clothes. It may even exacerbate the wear and tear on the main components due to long-term uneven stress, reducing the service life of the equipment. Therefore, there is an urgent need for a technical solution to solve the above problems.

[0033] To overcome the above technical problems, this application provides a suspension component that can be installed on the clothes rack of a clothes drying rack to connect with the steel wire rope 5 of the main unit, thereby realizing the suspension function of the clothes rack. Furthermore, the suspension component of this solution has a height adjustment function, which can level the clothes rack through its own adjustment, compensating for the defect of uneven lengths of the steel wire ropes 5 at both ends.

[0034] Reference Figure 1 and Figure 2 The suspension assembly in this embodiment includes: Fixing bracket 1, used to fix it to the clothes rack; The cable holder 2 is movably installed on the fixed frame 1; the cable holder 2 is provided on one side with a cable clamping groove 21 that allows the steel wire rope 5 to be inserted laterally; Adjustment component 4 is installed on the fixed frame 1 and is connected to the cable holder 2. The installation height of the cable holder 2 on the fixed frame 1 can be adjusted by the adjustment component 4. Locking element 3, installed on the wire fixing frame 2, is used to lock the rope head 51 at the end of the wire rope 5 to restrict the movement of the rope head 51 relative to the wire fixing frame 2.

[0035] Among them, the fixing frame 1 serves as the basic load-bearing structure. It is made of rigid materials (such as metal plates or high-strength plastics) and is fixed to the end of the clothes rack or the preset installation position by means of bolts, buckles or welding. It provides a stable installation base for the entire suspension assembly and ensures the stability of the overall structure during the adjustment process.

[0036] The cable holder 2 is a movable and adjustable core component. It is connected to the fixed frame 1 by sliding or rotating structures such as a slide groove 141, guide rail, or bushing, and can move flexibly along the height direction of the fixed frame 1. A cable clamping groove 21 with a lateral opening is provided on one side. The width of the groove is adapted to the diameter of the wire rope 5, allowing the wire rope 5 to be quickly clamped in from the side and limiting the rope end 51 to prevent the wire rope 5 from detaching from the cable holder 2 during adjustment.

[0037] Adjusting component 4 is a driving component for height adjustment. It typically uses a bolt, screw, or eccentric wheel structure and is installed horizontally or vertically on the fixed frame 1. Taking bolt adjustment as an example, the screw end of adjusting component 4 is threadedly connected to or abuts against the cable holder 2. By rotating adjusting component 4, the cable holder 2 can be pushed up or down along the fixed frame 1 to achieve precise adjustment of the installation height.

[0038] Locking element 3 is installed on wire fixing frame 2. When the wire rope 5 is inserted into the wire clamping groove 21, locking element 3 can firmly fix the rope end 51 (usually a pressed metal rope buckle or braided knot) of the wire rope 5, preventing the rope end 51 from sliding relative to the wire fixing frame 2 and ensuring the stability of the adjusted height position. Optionally, locking element 3 can be a pressure block with bolts, which is connected to the wire fixing frame 2 by threads. When the wire rope 5 is inserted, tightening the bolts will press the pressure block against the rope end 51 of the wire rope 5; or a wedge lock can be used, which locks the rope end 51 by striking the wedge block, suitable for high-strength wire rope 5 scenarios.

[0039] When the two ends of the clothes rack have a height difference due to the difference in the length of the steel wire rope 5, the installation height of the fixing frame 2 can be changed by operating the adjusting component 4: if the clothes rack on one side is too low (corresponding to the actual length of the steel wire rope 5 being too long), the fixing frame 2 can be lowered by adjusting the component 4 to shorten the effective hoisting length of the steel wire rope 5 on that side, thus raising that side of the clothes rack; if the clothes rack on one side is too high (corresponding to the actual length of the steel wire rope 5 being too short), the fixing frame 2 can be raised by adjusting the component 4 to increase the effective hoisting length of the steel wire rope 5 on that side, thus lowering that side of the clothes rack; finally, by adjusting one or both sides, the height of both ends of the clothes rack can be made consistent, thus achieving the purpose of leveling.

[0040] In addition, after long-term use of the clothes drying rack, if the steel wire rope 5 on one side becomes loose, the loose steel wire rope 5 will undergo undirected lateral displacement. At this time, the steel wire rope 5 may accidentally slip off from the side opening of the cable clamping groove 21. Once the steel wire rope 5 slips off, the clothes rack on that side will lose its suspension support, directly causing a safety accident of the clothes rack falling on one side. This may not only damage the clothes, but also pose a potential risk of injuring the user.

[0041] To overcome the above problems, the locking component 3 in this embodiment uses a rigid connection structure (such as bolt crimping, wedge locking, etc.) with the wire rod frame 2 to firmly fix the rope end 51 of the wire rope 5 to the lower side of the wire rod frame 2. This fixing method makes the rope end 51 and the wire rod frame 2 form a fixed whole that cannot move relative to each other. Even if the wire rope 5 becomes slack to a certain extent, the rope end 51 will not leave the constraint range of the wire rod frame 2, ensuring that the wire rope 5 is always stably locked in the wire clamping groove 21. At the same time, the fixing of the rope end 51 by the locking component 3 can also prevent the wire rope 5 from shifting due to changes in force during winding and unwinding, maintaining the lateral limiting effect of the wire clamping groove 21 on the wire rope 5. From the structural design, this completely eliminates the hidden danger of the clothes rack falling to one side, and significantly improves the safety and reliability of the suspension component.

[0042] Based on the suspension assembly provided in this embodiment, the mechanical adjustment structure can specifically compensate for the length error or deformation difference of the steel wire rope 5, solve the problem of inconsistent height at both ends of the clothes rack, ensure that clothes are dried evenly, and avoid clothes slipping or drying unevenly due to tilting. At the same time, a locking piece 3 is set to fix the rope end 51 to prevent slippage. Multiple structures ensure the safety of the suspension structure and avoid safety hazards caused by loosening and slipping of the steel wire rope 5.

[0043] In one embodiment, the locking member 3 is provided with a clamping part 33, and the locking member 3 clamps the rope end 51 through the clamping part 33.

[0044] Specifically, the clamping part 33 can adopt a symmetrical jaw 331 structure, an arc-shaped pressure plate, or a clamping surface design with anti-slip texture, and its size is adapted to the diameter or shape of the wire rope 5 end 51. When the wire rope 5 end 51 (such as a pressed metal collar, braided knot, etc.) is inserted into the wire clamping groove 21 of the wire fixing frame 2, the clamping part 33 of the locking member 3 applies a clamping force to the wire rope end 51 to fix the wire rope end 51. For example, the locking member 3 includes a clamping block with a double-ended bolt. When the bolt is rotated, the clamping parts 33 on both sides gradually move closer, and the wire rope end 51 is wrapped and clamped by mechanical force; or the clamping part 33 adopts an elastic metal sheet structure, and the elastic deformation of the metal sheet uses continuous elastic force to firmly fix the wire rope end 51 to the lower side of the wire fixing frame 2.

[0045] In this embodiment, the design of clamping the rope end 51 by clamping the clamping part 33 can significantly improve the connection strength between the rope end 51 and the wire frame 2. On the one hand, the contact surface between the clamping part 33 and the rope end 51 is larger, which can disperse the clamping force and avoid excessive local stress that could damage the rope end 51. On the other hand, the static friction and mechanical limiting force formed by the clamping action can effectively resist the slippage of the wire rope 5 when it is slack or the impact of external forces, ensuring that the rope end 51 is always stably constrained on the wire frame 2. Structurally, this further prevents the risk of the rope end 51 slipping off and ensures the suspension stability of the clothes rack.

[0046] In one embodiment, combined with Figure 5 and Figure 9 The clamping part 33 includes a plurality of clamps 331 arranged around the periphery of the rope head 51, and each clamp 331 clamps the periphery of the rope head 51.

[0047] The clamping part 33 of the locking member 3 adopts a multi-claw surrounding structure, specifically composed of several claws 331 evenly distributed around the rope head 51. These claws 331 are usually rigid metal plates (such as stainless steel or spring steel), and their number can be flexibly set according to the diameter of the wire rope 5 rope head 51 (for example, 3-4), arranged in a ring array at the rope head 51 fixing position of the wire rod holder 2. The inner contact surface of the claws 331 can be designed as an arc shape that matches the outer contour of the rope head 51, and anti-slip textures (such as serrated or grid-like protrusions) can be added to enhance the friction with the rope head 51.

[0048] In this embodiment, compared to a unidirectional pressing locking structure, the multi-claw wrap-around design can apply uniform clamping force from multiple directions around the rope end 51, avoiding deformation, breakage, or surface wear of the rope end 51 due to excessive force at a single point. This is especially suitable for fixing high-strength steel wire rope 5 or precision metal collar rope end 51. Because the contact surface between the claws 331 and the rope end 51 is larger, and the multi-directional wrap-around structure can resist external forces from different angles (such as the shaking when the steel wire rope 5 is slack, or the lateral pulling force when clothes are being dried), even if one claw 331 becomes slightly loose due to wear, the other claws 331 can still maintain the locking effect, significantly improving the overall anti-slip reliability.

[0049] In one embodiment, combined with Figure 6 The clamping part 33 expands upwards, allowing the rope head 51 to move upwards and squeeze open the clamping part 33 and enter its clamping space. The clamping part 33 can also clamp the rope head 51 with elastic restoring force to prevent the rope head 51 from moving downwards.

[0050] Specifically, the root of the clamping part 33 is connected to the main body of the locking member 3 via an elastic hinge (such as a spring plate or torsion spring) or an elastic deformation structure. In its natural state, it is in a closed or semi-closed state, forming a surrounding clamping space. The expansion direction of the clamping part 33 is designed to expand upward. That is, when an external force is applied from below (the rope head 51 moves from bottom to top), the clamping claw 331 can open outward in an upward direction, expanding the entrance to the clamping space; while when the external force disappears or the direction is reversed (the rope head 51 moves downward), the clamping claw 331 cannot open outward, but can only tighten inward through elastic force, thereby achieving the purpose of clamping the rope head 51.

[0051] For ease of installation, the lower end diameter of the clamping space is larger than the diameter of the rope head 51, and the end of the clamp 331 is provided with a guide slope (such as an outwardly inclined arc transition surface). When the user aligns the rope head 51 of the wire rope 5 with the clamping part 33 from below and pulls the wire rope 5 upward, the rope head 51 will push the guide slope of the clamp 331 upward, forcing the clamp 331 to overcome the elastic force and open upward (expand accordingly). It can automatically squeeze open the clamping part 33 and enter the internal clamping space without manual operation. When the upper end of the rope head 51 is restricted (such as by the limiting part on the wire fixing frame 2 or the locking part 3), the clamp 331 automatically tightens under the action of elastic restoring force (such as the rebound force of the spring plate, the deformation restoring force of the metal clamp 331), and hugs the rope head 51 from the periphery. If the rope end 51 attempts to move downwards in the opposite direction due to gravity or external force, the gripper 331 will be unable to open outwards due to structural limitations (such as barbs or one-way teeth on the inner side of the gripper 331). Instead, the downward pull of the rope end 51 will further increase the clamping force, forming a one-way locking effect of "the more you pull, the tighter it gets".

[0052] It should be noted that the clamping part 33 clamps the rope end 51 by friction, not by a completely mechanical lock. As long as it can prevent the rope end 51 from moving freely when the wire rope 5 slackens, it is sufficient. When disassembly is required, the operator can use a tool to pull the rope end 51 downwards to pull it out of the clamping space of the clamping part 33.

[0053] In this embodiment, during installation, there is no need to manually pry open the clamp 331 or adjust the locking element 3. The rope end 51 can be automatically pushed into the clamping space by the upward pushing force, achieving quick installation with a simple pull. This solves the cumbersome problem of traditional locking structures requiring manual alignment and tightening, making it especially suitable for elderly users or those with operational difficulties. The elastic restoring force ensures that the clamp 331 always applies a stable clamping force to the rope end 51, while the one-way anti-reverse design eliminates the possibility of the rope end 51 slipping off in reverse from a mechanical principle. Even under long-term alternating loads (such as shaking when clothes are being dried or changes in tension during lifting), it can still maintain the locked state, reducing safety hazards.

[0054] In one embodiment, combined with Figures 5-7 The locking member 3 is provided with an inner support portion 32, which can extend into the wire-locking groove 21 and press against the inner wall of the wire-locking groove 21 to fix the locking member 3 to the wire-fixing frame 2.

[0055] The inner support 32 is typically an elastic protrusion extending from the main body of the locking member 3 (such as an inclined elastic claw, a radially expandable plastic support block, or a metal spring), and its position is adapted to the cable clamping groove 21 of the cable holder 2. When the locking member 3 is installed on the cable holder 2, the inner support 32 can extend axially along the cable clamping groove 21 into the groove space, and apply continuous compressive force to the inner wall of the cable clamping groove 21 through its own elastic deformation or mechanical drive (such as threaded tightening). The inner wall of the cable clamping groove 21 is a rigid structure. Under the compressive action of the inner support 32, a large static friction force is generated between the two, which ultimately firmly fixes the locking member 3 to the cable holder 2, preventing it from loosening or shifting during use.

[0056] In this embodiment, compared to traditional single bolt fixing or snap-fit ​​connections, the frictional force generated by the inner support 32 through compression is more evenly distributed, which can adapt to external impacts under different working conditions (such as vibrations during clothes rack lifting and lowering, and lateral forces caused by clothing shaking). Even if slight wear occurs after long-term use, the connection strength can still be maintained by the continuous pressure of the elastic inner support 32, reducing the risk of loosening. The elastic deformation characteristics of the inner support 32 can accommodate certain installation errors. For example, when there is a slight deviation in the size of the cable slot 21, the inner support 32 can adapt by expanding or contracting itself, reducing the dependence on the precision of parts during installation and facilitating quick assembly or later maintenance and replacement by users.

[0057] In one embodiment, reference is made to Figure 9 and Figure 10 The inner support portion 32 includes a plurality of expansion claws 321 arranged in multiple directions along the inner wall of the wire clamping groove 21, and each expansion claw 321 presses against the inner wall of the wire clamping groove 21.

[0058] The expansion claws 321 are typically elastic metal sheets or high-strength plastic claws extending from the main body of the locking member 3. Their number is determined by the cross-sectional shape of the wire-locking groove 21 (e.g., 3-4), and they are arranged radially or symmetrically. Their arrangement precisely matches the inner wall contour of the wire-locking groove 21: if the wire-locking groove 21 has a circular cross-section, the expansion claws 321 are evenly distributed along the circumference, pointing towards the inner wall outside the center; if it has a square or irregular cross-section, the expansion claws 321 correspond to the upper, lower, left, and right inner walls of the groove, forming a multi-directional encircling layout. Each expansion claw 321 has an arc-shaped contact surface at its end (fitting against the inner wall of the wire-locking groove 21), and its root is connected to the main body of the locking member 3 via an elastic hinge or deformation segment, possessing elastic potential energy for outward expansion.

[0059] In this embodiment, compared to a unidirectional internal support structure, the multi-directional expansion claw 321 distributes pressure from multiple dimensions, preventing deformation or wear caused by excessive local stress on the wire clamping groove 21. Simultaneously, it ensures that the locking member 3 is centrally positioned within the wire clamping groove 21, reducing the risk of loosening due to eccentric stress. Regardless of whether the wire clamping groove 21 is circular, square, or has an irregular cross-section, the multi-directional expansion claw 321 can achieve a complete fit by adjusting its arrangement angle, eliminating the need for separate design for specific groove types. This enhances the versatility of the component and reduces mold development costs.

[0060] In one embodiment, reference is made to Figure 6 The inner support 32 retracts upwards, allowing the upward-pointing rope end 51 to push the inner support 32 into the wire-locking groove 21. The inner support 32 can also be fixed by squeezing the inner wall of the wire-locking groove 21 with its elastic restoring force.

[0061] Specifically, the expansion claw 321 of the inner support 32 adopts a unidirectional oblique elastic structure. The root is connected to the main body of the locking member 3, and the end naturally opens outward (the radial dimension in the uninstalled state is slightly larger than the inner diameter of the wire clamping groove 21). The tilting direction of the claw body forms an acute angle with the axial direction of the wire clamping groove 21. When the locking member 3 is aligned with the wire clamping groove 21 from the lower side of the wire fixing frame 2, the outer edge of the expansion claw 321 forms a guiding contact with the lower port of the wire clamping groove 21.

[0062] During installation, the user only needs to apply an upward pushing force to the locking member 3 (pushing the locking member 3 to move upward along the axial direction of the wire-locking groove 21). The side wall of the wire-locking groove 21 will exert a radially inward squeezing force on the expansion claw 321. Since the elastic structure of the expansion claw 321 is designed to contract only in the upward direction (the claw body can contract and deform around the root), this squeezing force will force the expansion claw 321 to retract towards the center, reducing its overall radial dimension, thus allowing it to smoothly enter the wire-locking groove 21. After the inner support 32 is engaged in the wire-locking groove 21, the expansion claw 321 opens outward under its own elastic restoring force, re-adhering tightly to the inner wall of the wire-locking groove 21 and applying radial pressure. At this time, if you try to pull the locking piece 3 down (reverse operation), the side wall of the wire clamping groove 21 will generate a downward reaction force on the expansion claw 321. Since the expansion claw 321 cannot retract downward (structural limitation), the outer surface of the claw body is tightly attached to the inner wall of the wire clamping groove 21. Through continuous radial elastic force, the inner wall is pressed tightly, and a reliable connection with the wire fixing frame 2 is achieved.

[0063] In this embodiment, the user only needs to push upwards to complete the assembly, without manually adjusting the inner support 32 or using tools, making it particularly suitable for quick installation or later maintenance in home settings. Because of the unidirectional contraction characteristic of the expansion claw 321, the locking member 3, once installed, cannot disengage downwards, further reducing the risk of accidental detachment of the locking member 3 from a structural principle perspective.

[0064] In one embodiment, reference is made to Figure 6 and Figure 10 An upper retaining ring 322 is provided on the top side of the inner support part 32. The diameter of the upper retaining ring 322 is larger than the diameter of the wire rope 5 and smaller than the diameter of the rope head 51, so that the rope head 51 can push the inner support part 32 upward through the upper retaining ring 322 and enter the wire clamping groove 21.

[0065] In this embodiment, during installation, the wire rope 5 first passes through the inner hole of the upper retaining ring 322. The rope end 51, because its diameter is larger than the hole diameter of the upper retaining ring 322, is blocked by the retaining ring and creates resistance. At this time, the user pulls the wire rope 5 upwards, and the thrust of the rope end 51 is transmitted through the upper retaining ring 322 to the entire inner support part 32, causing the locking member 3 to move axially upwards along the wire clamping groove 21. This achieves the installation of the locking member 3 using the wire rope 5, thus simplifying the installation process. Furthermore, the upper retaining ring 322 evenly transmits the thrust of the rope end 51 to the entire inner support part 32, preventing the expansion claw 321 from tilting due to single-point force, making the expansion claw 321 contract more synchronously, and significantly reducing the thrust required for installation.

[0066] In one embodiment, reference is made to Figures 6-8 The wire slot 21 includes an upper slot area 211 and a lower slot area 212, which are arranged vertically. The width of the lower slot area 212 is greater than the width of the upper slot area 211. The inner support 32 enters the lower slot area 212 and is in close contact with the inner wall of the lower slot area 212. The inner support 32 is restricted below the upper slot area 211.

[0067] The upper slot area 211 is located in the upper half of the cable slot 21. It is narrower (slightly larger than the diameter of the wire rope 5 but smaller than the maximum diameter of the inner support 32 after expansion). It is mainly used to limit the upward range of the inner support 32 and provide stable lateral restraint for the wire rope 5. The lower slot area 212 is located in the lower half of the cable slot 21. It is wider (smaller than the maximum diameter of the inner support 32 after expansion). It serves as the installation and fixing area for the inner support 32. Its inner wall provides a contact surface and friction for the inner support 32. The two areas are connected by steps or slopes to form a stepped structure that is narrower at the top and wider at the bottom.

[0068] During installation, when the locking member 3 is pushed upward, the inner support 32 first enters the wider lower slot area 212. Because the lower slot area 212 is wide enough, the expansion claw 321 can open and adhere tightly to its inner wall under the action of elastic restoring force. When the inner support 32 moves upward to the boundary between the upper and lower slot areas 212, because the width of the upper slot area 211 is narrower than the diameter of the inner support 32 after contraction (generally set to be smaller than the diameter of the upper retaining ring 322), the inner support 32 will come into contact with the top wall of the lower slot area 212 and cannot continue to move upward. This structural limitation ensures that the inner support 32 is precisely confined within the lower slot area 212, preventing positional displacement due to over-installation.

[0069] In this embodiment, the inner support 32 is restricted to the preset lower slot area 212 each time it is installed by the physical blocking of the upper slot area 211. This eliminates the need for the user to manually determine the installation position, completely eliminating the problem of fixation failure caused by installation that is too deep or too shallow, and improving assembly consistency.

[0070] In one embodiment, the locking member 3 includes a connecting body 31, an inner support portion 32, and a clamping portion 33. The inner support portion 32 and the clamping portion 33 are respectively connected to the upper and lower sides of the connecting body 31. The inner support portion 32 can extend into the wire-locking groove 21 and press the inner wall of the wire-locking groove 21 so that the locking member 3 is fixed to the wire-fixing frame 2. The clamping portion 33 can clamp the rope end 51.

[0071] The integrated locking component 3 design of the connector 31, inner support 32 and clamping part 33 in this embodiment achieves functional synergy through structural integration, which not only enhances the fixation reliability and load-bearing capacity, but also simplifies the installation operation.

[0072] In one embodiment, the locking member 3 is provided with an insertion groove 34 that passes through the inner support portion 32, the connecting body 31 and the clamping portion 33, and the wire rope 5 can be inserted into the locking member 3 through the insertion groove 34.

[0073] The insertion groove 34 is a strip-shaped groove opened along the axial direction of the locking member 3, passing through the connector 31 from the top of the inner support 32 and extending to the bottom of the clamping part 33, forming a complete lateral opening channel. The insertion groove 34 allows the wire rope 5 to be inserted laterally rather than axially, forming a more convenient assembly method in conjunction with the overall structure of the locking member 3.

[0074] During installation, the locking member 3 is pre-fixed to the cable clamping groove 21 of the cable holder 2, and the orientation of the insertion groove 34 of the locking member 3 is the same as that of the cable clamping groove 21. Then, the wire rope 5 is aligned with the insertion groove 34 from the side and pushed in along the groove opening. After the wire rope 5 is inserted into the insertion groove 34, the wire rope 5 is pulled upward, causing the lower rope head 51 to push open the clamping part 33 and enter the insertion groove 34. Then, the rope head 51 further pushes the entire locking member 3 upward to the limit position, so that the inner support part 32 is installed in the cable holder 2, and at the same time, the clamping part 33 clamps the rope head 51.

[0075] This embodiment greatly simplifies the connection operation of the wire rope 5 through the side insertion groove 34. It is especially suitable for old machine retrofitting or after-sales maintenance scenarios. Specifically, for the wire rope 5 already installed on the host (the rope end 51 is fixed and cannot be removed), the side insertion design eliminates the need to thread the wire rope 5 through the end. Users can directly snap the locking piece 3 into the existing wire rope 5, significantly reducing the installation difficulty.

[0076] In one embodiment, reference is made to Figure 1 and Figure 3 The adjusting component 4 is rotatably mounted on the fixed frame 1. The adjusting component 4 includes a threaded rod 41. The wire fixing frame 2 is provided with a threaded hole 22 that cooperates with the threaded rod 41. The installation height of the wire fixing frame 2 is adjusted by rotating the adjusting component 4.

[0077] The adjusting component 4 is rotatably mounted on the fixed frame 1. For example, the adjusting component 4 can be rotatably mounted on the fixed frame 1 via a bearing, bushing, or reserved hole. When rotating, its axial position is fixed (it only rotates around the axis and does not produce vertical displacement). A threaded hole 22 is provided on the cable holder 2 at the position corresponding to the threaded rod 41 of the adjusting component 4. The internal thread of the threaded hole 22 matches the external thread of the threaded rod 41 to form a threaded pair connection. When the adjusting component 4 rotates, the threaded rod 41 drives the cable holder 2 to move axially (vertically) through thread engagement, thereby realizing the adjustment of the installation height.

[0078] In this embodiment, the use of threaded transmission enables height adjustments at the millimeter or even micrometer level. Compared to snap-fit ​​or pin-hole type adjustments, this method more precisely compensates for minute length deviations in the wire rope 5, ensuring the clothes rack is perfectly level, and the adjustment process is simple. The threaded rod 41, threaded hole 22, and other structures can be achieved through conventional machining, requiring no complex processes and suitable for mass production.

[0079] In one embodiment, the fixing frame 1 includes a main vertical plate 11 and a first horizontal plate 12 and a second horizontal plate 13 respectively vertically connected to the upper and lower sides of the main vertical plate 11. The adjusting member 4 is provided with a first limiting part 42 and a second limiting part 43 at both ends. The first limiting part 42 abuts against the side of the first horizontal plate 12 facing away from the second horizontal plate 13, and the second limiting part 43 abuts against the side of the second horizontal plate 13 facing away from the first horizontal plate 12, so as to restrict the vertical movement of the adjusting member 4. The cable fixing frame 2 is located between the first horizontal plate 12 and the second horizontal plate 13.

[0080] The main vertical plate 11 serves as the main supporting structure, extending vertically to provide the mounting base for the first and second horizontal plates 13. The first horizontal plate 12 is horizontally and vertically connected to the top of the main vertical plate 11, extending horizontally (towards the cable holder 2), with a side opening in the middle for the adjustment component 4 to pass through. The second horizontal plate 13 is parallel to the first horizontal plate 12, horizontally and vertically connected to the bottom of the main vertical plate 11, with a side opening in the middle coaxial with the side opening of the first horizontal plate 12, forming a double-point support for the adjustment component 4. The three components together form a "U"-shaped space, providing a channel for the cable holder 2 to move up and down.

[0081] In this embodiment, the rigid contact between the double limiting parts and the double horizontal plates completely eliminates the axial movement of the adjusting component 4, making the threaded transmission smoother and avoiding adjustment jamming or thread wear caused by shaking. This ensures that the precise adjustment effect can still be maintained after long-term use. The bending strength of the "U"-shaped frame structure is better than that of a single vertical plate design. With the support of the double horizontal plates, it can withstand greater suspended loads (such as the weight of a full load of heavy clothes), making it especially suitable for the use of large-sized clothes racks.

[0082] In one embodiment, the fixing frame 1 further includes at least one side vertical plate 14 vertically connected to the main vertical plate 11, and the wire fixing frame 2 is slidably connected to the side vertical plate 14, guiding the vertical movement of the wire fixing frame 2 through the side vertical plate 14.

[0083] The side vertical plate 14 is vertically connected to one or both sides of the main vertical plate 11 (symmetrically arranged), and together with the main vertical plate 11, the first horizontal plate 12, and the second horizontal plate 13, it encloses a rectangular or square guide space.

[0084] In this embodiment, the rigid guidance of the side vertical plate 14 solves the problem of easy displacement of the wire frame 2 in the traditional structure, making the lifting movement more stable. Especially when the adjusting component 4 becomes slightly loose after long-term use, it can still maintain normal adjustment function through the guiding constraint, reducing the probability of failure. At the same time, after the lateral force is dispersed through the side vertical plate 14, the stress distribution of each component of the fixing frame 1 is more uniform, which can prevent the main vertical plate 11 or the horizontal plate from plastic deformation due to excessive local stress, significantly improving the fatigue resistance of the components and extending the overall service life.

[0085] In one embodiment, the side vertical plate 14 is provided with a vertically extending slide groove 141, and a corresponding slider 23 is provided on the wire frame 2, with the slider 23 slidingly engaging with the slide groove 141.

[0086] When the adjusting component 4 drives the cable holder 2 to rise or fall, the slider 23 is confined within the slide groove 141 and can only move along the vertical trajectory of the slide groove 141. The two side walls of the slide groove 141 block the horizontal displacement of the slider 23, preventing the cable holder 2 from swaying left or right or tilting forward or backward, thus avoiding abnormal wear of the threaded connection due to tilting. When the clothes rack is under load or the tension of the wire rope 5 deviates, the lateral force generated by the cable holder 2 is transmitted to the side wall of the slide groove 141 through the slider 23. The slide groove 141 distributes the force to the side vertical plate 14 and the entire fixing frame 1, preventing the force from concentrating on the threaded part of the adjusting component 4, and further enhancing the structural stability.

[0087] In one embodiment, combined with Figure 4 The fixing frame 1 is provided with a wire hole 15 that allows the wire rope 5 and its head 51 to be inserted laterally, so that the wire rope 5 can be inserted laterally into the wire clamping groove 21.

[0088] This bracket 1 design with a side-opening wire passage hole 15 breaks through the limitations of traditional axial wire threading by non-removable side insertion, improving installation convenience while maintaining structural reliability.

[0089] On the other hand, a clothes rack is provided, including the aforementioned suspension components.

[0090] On the other hand, this embodiment also provides a clothes drying rack, including the above-mentioned suspension components.

[0091] Specifically, the clothes rack in this embodiment includes a scissor-type lifting bracket 6 and two parallel drying rods. The upper and lower ends of the lifting bracket 6 are respectively provided with an upper guide rail and a lower guide rail 61. The upper guide rail is installed on the main unit of the clothes drying machine, and the two ends of the lower guide rail 61 are respectively connected to the two drying rods.

[0092] like Figure 12 and Figure 13 As shown, the suspension assembly is installed in the middle of the lower guide rail 61 of the bracket. The lower guide rail 61 of the bracket is raised and lowered by the extension and retraction of the steel wire rope 5, which in turn drives the clothes drying rods on both sides to rise and fall, thus realizing the purpose of electrically driving the clothes drying rack to rise and fall.

[0093] Based on the suspension components of this embodiment, the clothes rack of this embodiment also has the advantages of easy adjustment of the height of both sides of the clothes rack and good stability of the suspension structure.
