Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothes drying rack technology, specifically a clothes drying rack hand crank with two hooks inside the connector. Background Technology
[0002] In daily life, clothes racks are essential household items, and the hand crank is the core mechanical component of a lifting clothes rack. The hand crank drives the shaft to rotate and drive the wire rope to wind up and down the clothes rack. The quality of the hand crank directly affects the smoothness of the clothes rack's lifting and lowering, the reliability of its self-locking mechanism, and its overall service life.
[0003] In existing technologies, most hand cranks only have a single hook, requiring two hand cranks to be operated at each end of the clothes drying rack. This makes it difficult to load and unload clothes when they are piled up. The internal structure design also has many unreasonable aspects. For example, the fit between the winding wheel and related components is not tight enough, which can easily cause jamming during the raising and lowering of the clothes drying rack, affecting the smoothness of use. Moreover, most hand cranks are also cumbersome to operate, requiring both hands to switch hooks, making it impossible to complete the task quickly with one hand. Therefore, we propose a clothes drying rack hand crank with two hooks in the connector to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of inconvenient operation of traditional hand cranks with a single hook, easy derailment of the wire rope, and inability to switch hooks with one hand in the prior art.
[0005] The specific solution of this utility model is as follows:
[0006] Design a clothes rack hand crank with two hooks inside the connector, including a hand crank shell, a rotating bearing rotatably connected to the inner wall of the hand crank shell, a rotating rod rotatably connected to the inner wall of the rotating bearing, a nut fixedly connected to the surface of the rotating rod, a rotating core slidably connected to the surface of the nut, a first winding wheel rotatably connected to the inner wall of the rotating core, a protrusion fixedly connected to the surface of the first winding wheel, the surface of the protrusion being movably connected to the inner wall of the rotating core, an end cap provided at the upper end of the rotating core, a torsion spring rotatably connected to the inner wall of the end cap, and elbows fixedly connected to both ends of the torsion spring, the surfaces of the two elbows being fixedly connected to the inner wall of the rotating core.
[0007] In a specific implementation, a pull cap is provided on the left side of the hand crank housing. A second winding wheel is rotatably connected to the inner wall of the pull cap. A hanging rope is wound around the inner wall of the second winding wheel. One end of the hanging rope passes through the surface of the hand crank housing and extends into the interior of the hand crank housing. A rope loop is fixedly connected to one end of the hanging rope. The other end of the hanging rope passes through the surface of the hand crank housing and extends into the interior of the first winding wheel. The other end of the hanging rope is fixedly connected to the inner wall of the first winding wheel.
[0008] In specific implementation, the upper end of the rotating rod penetrates the inner wall of the rotating core and extends to the inner wall of the end cap. The upper end of the rotating rod is rotatably connected to the inner wall of the end cap. The lower end of the rotating rod penetrates the inner wall of the hand crank housing and extends to the outside of the hand crank housing. A crank handle is fixedly connected to the lower end of the rotating rod.
[0009] In a specific implementation, the surface of the hand crank housing has two adjacent perforations, namely a first perforation and a second perforation. The inner diameter of the first perforation is the same as the outer diameter of the rope loop, and the inner diameter of the second perforation is larger than the outer diameter of the rope loop.
[0010] In a specific implementation, a third through hole is provided on the surface of the first winding wheel, and the inner wall of the third through hole is connected to the inner wall of the first winding wheel. The third through hole is located on the left side of the protrusion.
[0011] In practice, the hanging rope is made of multiple stainless steel wires with a diameter of 1mm, and the length of the hanging rope is 6m.
[0012] The beneficial effects of this utility model are as follows:
[0013] This invention achieves the function of two hooks through structural design within the connector, indirectly realizing the effect of multiple hooks through structures such as hanging ropes. This allows more clothes to be dried at the same time, meeting the needs of users in daily life and improving the efficiency of the clothes rack.
[0014] This invention makes the rotation of the rotating rod smoother by setting a rotating bearing. At the same time, the sliding connection between the nut and the rotating core and the movable connection between the protrusion and the inner wall of the rotating core ensure the tightness of the fit between the components, reducing the probability of jamming during the use of the hand crank. Moreover, this invention can complete the hook switching in a few seconds, which greatly improves the efficiency of daily operation. Attached Figure Description

Detailed Implementation
[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0021] Example 1
[0022] A hand crank for a clothes rack with two hooks integrated into the connector, see [link to details]. Figures 1 to 3 The design includes a hand crank housing 1, a rotating bearing 2 rotatably connected to the inner wall of the hand crank housing 1, a rotating rod 3 rotatably connected to the inner wall of the rotating bearing 2, a nut 4 fixedly connected to the surface of the rotating rod 3, a rotating core 5 slidably connected to the surface of the nut 4, a first winding wheel 6 rotatably connected to the inner wall of the rotating core 5, a protrusion 7 fixedly connected to the surface of the first winding wheel 6, the surface of the protrusion 7 being movably connected to the inner wall of the rotating core 5, an end cap 8 provided at the upper end of the rotating core 5, a torsion spring 9 rotatably connected to the inner wall of the end cap 8, and elbows 10 fixedly connected to both ends of the torsion spring 9, the surfaces of the two elbows 10 being fixedly connected to the inner wall of the rotating core 5.
[0023] A pull cap 11 is provided on the left side of the hand crank housing 1. A second winding wheel 12 is rotatably connected to the inner wall of the pull cap 11. A hanging rope 13 is wound on the inner wall of the second winding wheel 12. One end of the hanging rope 13 passes through the surface of the hand crank housing 1 and extends into the interior of the hand crank housing 1. A rope loop 14 is fixedly connected to one end of the hanging rope 13. The other end of the hanging rope 13 passes through the surface of the hand crank housing 1 and extends into the interior of the first winding wheel 6. The other end of the hanging rope 13 is fixedly connected to the inner wall of the first winding wheel 6. The second winding wheel 12 and the hanging rope 13 are integrated by the pull cap 11, so that the rope loop 14 constitutes an independent hook, thereby realizing the linkage control of the double hook.
[0024] The upper end of the rotating rod 3 passes through the inner wall of the rotating core 5 and extends to the inner wall of the end cover 8. The upper end of the rotating rod 3 is rotatably connected to the inner wall of the end cover 8. The lower end of the rotating rod 3 passes through the inner wall of the hand crank housing 1 and extends to the outside of the hand crank housing 1. The lower end of the rotating rod 3 is fixedly connected to the crank handle 15. The rotating rod 3 passes through the rotating core 5 to connect the end cover 8 and the crank handle 15, forming a bidirectional transmission structure to ensure that the crank handle 15 can synchronously drive the first winding wheel 6 when driving the rotating rod 3.
[0025] The surface of the hand crank housing 1 has two adjacent first through holes 16 and second through holes 17. The inner diameter of the first through hole 16 is the same as the outer diameter of the hanging rope 13, and the inner diameter of the second through hole 17 is larger than the outer diameter of the hanging rope 13. By setting the first through hole 16 and the second through hole 17, the hanging rope 13 is limited and fixed and can be quickly taken out. It supports one-handed hook switching, and the hanging rope 13 is not easy to get tangled.
[0026] The surface of the first winding wheel 6 is provided with a third through hole 18. The inner wall of the third through hole 18 is connected to the inner wall of the first winding wheel 6. The third through hole 18 is located on the left side of the protrusion 7. By setting the third through hole 18, an eccentric force release channel is provided for the hanging rope 13, realizing the anti-derailment function, and also facilitating the maintenance when the hanging rope 13 malfunctions.
[0027] The hanging rope 13 is made of multiple stainless steel wires with a diameter of 1mm, and the length of the hanging rope 13 is 6m. The high-strength stainless steel wire enhances the practicality and durability of the equipment.
[0028] During operation, turning the crank handle 15 causes the rotating rod 3 to rotate, which in turn causes the rotating core 5 to move. The rotating core 5 drives the first winding wheel 6 to rotate via the protrusion 7. The rotation of the first winding wheel 6 causes the hanging rope 13 to retract and extend. The torsion spring 9 has elbows 10 at both ends. The rotating core 5 drives the torsion spring 9 to rotate freely on the inner wall of the end cover 8 via the elbows 10. When the crank handle 15 stops rotating, under the action of the elasticity of the hanging rope 13 and the weight of the clothes, the protrusion 7 on the first winding wheel 6 will drive the torsion spring 9 to reverse. When the torsion spring 9 reverses, it will expand outward and generate friction with the inner wall of the end cover 8. The friction and spring tension limit the rotation of the first winding wheel 6, realizing the real-time self-locking of the hand crank, which is convenient for actual use.
[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
