Description

Technical Field

[0001] This invention relates to the field of clothes rack reel technology, specifically to a clothes rack reel linkage device. Background Technology

[0002] The clothesline reel is the core transmission component controlling the raising and lowering of the clothesline. It's a mechanical part that moves the drying rod up and down by winding or releasing the clothesline cable. They are typically available in single-wheel and double-wheel types to suit different raising and lowering needs. Widely used in both manual and electric clotheslines for home use, their core function is to transmit power. Suitable for everyday household drying of clothes, bedding, etc., they allow for easy adjustment of the drying rod height without complicated operations, improving convenience. They are an indispensable key component in modern home drying equipment, adaptable to the drying needs of various apartment layouts. Existing clothes drying rack reel devices have many shortcomings: most adopt a single reel or parallel double-wheel design, the transmission structure layout is unreasonable, and the space utilization rate is low. At the same time, traditional tensioning devices have components on one side of the cable, which can easily cause cable deviation and misalignment during adjustment, affecting the lifting stability of the clothes drying rack and resulting in poor performance. Therefore, it is necessary to propose a clothes drying rack reel linkage device. Summary of the Invention

[0003] To address the problems in the prior art, the present invention provides a clothes rack reel linkage device.

[0004] The technical solution adopted by this invention to solve its technical problem is: a clothes rack reel linkage device, including a housing, a front sealing plate, and a rear mounting plate. A limiting plate is fixedly connected to the front end of the housing. A support plate is installed on the outer wall of the limiting plate. A servo motor is installed on the top of the support plate. A transmission shaft is fixedly connected to the output end of the servo motor. A pulley is fixedly connected to one end of the transmission shaft. A driven shaft is rotatably connected to the other end of the limiting plate. A pulley is fixedly connected to one side of the shaft wall of the driven shaft. A transmission belt is connected between the pulley and the pulley. A first spool is fixedly connected to the other side of the driven shaft wall. A universal joint is fixedly connected to one end of the first spool. A rotating rod is fixedly connected to one end of the universal joint. A second spool is fixedly connected to the wall of the rotating rod. U-shaped frames are fixedly connected to both ends of the rotating rod wall. A fixing block is fixedly connected to the lower end of the inner side wall of the housing. A screw is threadedly connected to the fixing block. The screw and the U-shaped frame are rotatably engaged. A hexagonal inner groove is opened at the bottom of the screw.

[0005] Specifically, the front sealing plate is connected to the opening end of the housing by several bolts.

[0006] Specifically, the edges of the rear mounting plate are each threaded with several mounting bolts.

[0007] Specifically, the top of the housing has holes that penetrate through the tops of both the first and second reels, and an inner sliding sleeve is engaged inside each hole.

[0008] Specifically, a protrusion is fixedly connected to the top of the screw, and the protrusion is rotatably engaged with the bottom of the U-shaped frame.

[0009] Specifically, a through hole is provided at the bottom end of the housing corresponding to the screw, and a sealing plug is engaged at the inner end of each through hole.

[0010] Specifically, both the first and second reels are arranged vertically.

[0011] The first beneficial effect of this invention is that the device achieves vertical synchronous transmission between spool one and spool two through the linkage design of servo motor, pulley assembly and universal joint, resulting in high transmission efficiency and stable power transmission. The vertically distributed double wheel structure optimizes the internal space layout of the housing, and together with the inner sliding sleeve in the hole at the top of the housing, it ensures smooth loading and unloading of the clothes drying cable, reduces cable wear, and extends service life. At the same time, the sealed connection between the front sealing plate and the housing, and the bolt fixing design of the rear mounting plate, make the device stable and highly protective, effectively preventing dust and foreign object intrusion, suitable for long-term household use, and significantly improving the reliability and practicality of the clothes drying rack's cable winding transmission. The second beneficial effect of this invention is its innovative vertical tension adjustment structure. Through the threaded engagement of the screw and the fixing block, the U-shaped frame and the reel are driven to rise and fall vertically. Compared to the problem of cable misalignment caused by traditional single-sided tensioning, this design precisely maintains the cable's alignment with the reel, preventing misalignment and tangling during winding and ensuring neat winding. The rotating engagement design between the protrusion at the top of the screw and the U-shaped frame ensures a smooth and stable adjustment process. The combination of the hexagonal inner groove and the sealing plug facilitates tool operation and adjustment while also providing dust protection. The overall adjustment structure is simple and efficient, allowing for fine-tuning of tension without complex disassembly, significantly improving the ease of use and adaptability of the clothes rack, and meeting the tension requirements of different cables.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-6 As shown, the present invention provides the following technical solution: Example 1: Clothes rack reel linkage device, including housing 1, front sealing plate 10 and rear mounting plate 11. The front sealing plate 10 is connected to the open end of housing 1 by several bolts, and the edges of the rear mounting plate 11 are threaded with several mounting bolts 12.

[0017] In use, the device can be securely installed in the preset position of the clothes rack by means of the mounting bolts 12 on the edge of the rear mounting plate 11. The front sealing plate 10 is closed with the housing 1 by bolts to form a protective cavity, which provides dustproof and damage protection for the internal transmission structure. The overall structure is simple and reliable, and can be used as a basic installation unit to adapt to the core transmission component assembly of the clothes rack, realizing the basic support for the winding and unwinding of the clothes drying cable.

[0018] Example 2: The technical solution of this example, which differs from Example 1, includes: a limiting plate 13 fixedly connected to the front end of the housing 1; a support plate 2 installed on the outer wall of the limiting plate 13; a servo motor 21 installed at the top of the support plate 2; a drive shaft fixedly connected to the output end of the servo motor 21; a pulley 22 fixedly connected to one end of the drive shaft; a driven shaft 23 rotatably connected to the other end of the limiting plate 13; a pulley 25 fixedly connected to one side of the shaft wall of the driven shaft 23; and a pulley 25 connected to the pulley... A transmission belt 24 is connected between the two shafts 22. A spool 26 is fixedly connected to the other side of the driven shaft 23. A universal joint 27 is fixedly connected to one end of the spool 26. A rotating rod 28 is fixedly connected to one end of the universal joint 27. A spool 29 is fixedly connected to the wall of the rotating rod 28. Holes 102 are opened through the top of the housing 1 at the top of the spools 26 and 29 respectively. An inner sliding sleeve 110 is engaged inside the holes 102. The spools 26 and 29 are both vertically distributed.

[0019] Among them, the servo motor 21 is connected to an external power supply through a controller; The 27-inch universal joint can accommodate a 90-degree adjustment. In use, the servo motor 21 is started, and its output end drives the pulley 22 to rotate through the transmission shaft. The pulley 25 and the driven shaft 23 are driven to rotate synchronously through the transmission belt 24, which in turn drives the spool 26 to rotate. The spool 26 transmits power to the rotating rod 28 through the universal joint 27, so that the vertically distributed spool 29 rotates synchronously. The clothes drying cable passes through the hole 102 at the top of the housing 1 and the inner sliding sleeve 110 respectively, and is wound on the spool 26 and the spool 29, realizing bidirectional synchronous winding or unwinding. The inner sliding sleeve 110 ensures smooth cable sliding and avoids wear.

[0020] Example 3: The technical solution of this example, which differs from that of Example 1, includes: a U-shaped frame 3 is fixedly connected to both ends of the rotating rod 28, a fixing block 31 is fixedly connected to the lower end of the inner side wall of the housing 1, a screw 33 is threadedly connected to the fixing block 31, the screw 33 and the U-shaped frame 3 are rotatably snapped together, a hexagonal inner groove 301 is opened at the bottom of the screw 33, a protrusion 32 is fixedly connected to the top of the screw 33, and the protrusion 32 is rotatably snapped at the bottom end of the U-shaped frame 3, a through hole 101 is opened at the bottom end of the housing 1 corresponding to the screw 33, and a sealing plug 30 is snapped into the inner end of each through hole 101.

[0021] In use, remove the sealing plug 30 inside the through hole 101 at the bottom of the housing 1, insert the adapter tool into the hexagonal inner groove 301 at the bottom of the screw 33 and rotate the screw 33. With the threaded engagement between the screw 33 and the fixing block 31, the top protrusion 32 rotates smoothly within the U-shaped frame 3, thereby driving the U-shaped frame 3 and the rotating rod 28 to move vertically up and down, achieving vertical tension adjustment of the cable reel 29. Compared to the traditional method of setting a tensioning component on one side of the cable, which easily leads to cable misalignment and affects winding regularity, this vertically downward tensioning method can always maintain the consistent contact trajectory between the cable and the cable reel 29, effectively preventing cable misalignment and ensuring a smooth and regular winding process. After adjustment, snap the sealing plug 30 back into the through hole 101 to provide dust and foreign object protection, ensuring the long-term stable operation of the tension adjustment structure.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
