Description
Technical Field
[0001] This application relates to the field of plug cords, and more particularly to a plug cord that is easy to store. Background Technology
[0002] Most plugs come with a power cord, which is usually quite long. Therefore, after use, the power cord needs to be stored away to avoid taking up space and creating a mess.
[0003] Referring to Chinese patent application CN221767093U, a power cord plug is disclosed. It includes a connector, one end of which has an extension member. The extension member and the connector together form a mounting groove. The connector is hollow and has several first mounting channels that communicate with the mounting groove. A mounting component is disposed within the mounting groove. The mounting component has several second mounting channels, and hardware components are disposed within the second mounting channels. The hardware components pass through the first mounting channels. A partition is disposed within the mounting groove. The mounting component has a clearance opening. The partition connects to the mounting component through the clearance opening. The partition separates the hardware components within the second mounting channels. This application provides precise positioning of the hardware components, improving installation efficiency and reducing the generation of defective products.
[0004] However, in existing technologies, when storing power cords, the cord is usually wrapped around the outside of the power plug. But after wrapping, it cannot be fixed and will still come loose, affecting the user's storage. In addition, the length of the power cord is fixed. When the appliance is close to the socket, there will be excess cord exposed. The excess cord will be placed in a disorderly manner, affecting the overall aesthetics of the environment. Therefore, we have designed a plug cord that is easy to store. Utility Model Content
[0005] The plug cord provided in this application provides a convenient storage solution to the technical problem that when storing power cords, they are usually wrapped around the outside of the power plug, but the wrapping is not secure and the cord will still come loose, affecting the user's storage.
[0006] This application provides a plug cord that is easy to store, including a mounting shell, a power cord, a winding mechanism, and a fixing mechanism. The power cord is wound inside the mounting shell by the winding mechanism. The winding mechanism includes a winding shaft, a spring, a fixing post, and an arc-shaped limiting plate. The fixing post is fixedly connected to the bottom of the mounting shell. The winding shaft is sleeved on the outer periphery of the fixing post and is rotatably connected to the fixing post. The arc-shaped limiting plate is fixedly installed inside the winding shaft and is disposed close to the inner wall of the arc-shaped limiting plate. The spring is wound around the inner periphery of the winding shaft. One end of the spring is connected to the fixing post, and the other end of the spring is fixedly connected to the outer periphery of the winding shaft.
[0007] The technical solutions described in this application embodiment have at least the following technical effects:
[0008] 1. This application, through the coordinated arrangement of a winding shaft, a spring, a fixing post, and an arc-shaped limiting plate, allows the power cord wound around the outer circumference of the winding shaft to be slowly released when pulled during use. Simultaneously, the spring wound around the inner circumference of the winding shaft slowly tightens towards the fixing post as the winding shaft rotates. When not in use, the fixing of the power cord is released, and the power cord will be wound back around the outer circumference of the winding shaft under the tension generated by the spring returning to its original state. This secures the power cord, preventing it from unraveling and affecting the user's storage. Furthermore, it keeps the power cord within the mounting housing, preventing it from being exposed when not in use and potentially damaged, thus affecting the use of the plug.
[0009] 2. This application, through the coordinated arrangement of a compression spring, connecting post, adapter, connecting cylinder, and pressing cylinder, allows the power cord to be stretched to a suitable length. By pushing the pressing cylinder downwards, the connecting post is inserted into the insertion hole, limiting and fixing the winding shaft to prevent further rotation. This secures the power cord around the winding shaft, preventing excess cord from protruding and haphazardly arranged, thus maintaining the aesthetics of the overall environment. Adjusting the power cord to a suitable length also facilitates the use and connection of the plug, further enhancing the practicality of the plug.
[0010] In some embodiments, a plurality of limiting holes are evenly provided on the outer periphery of the take-up shaft along the circumferential direction, and a middle section of the power cord is inserted into the limiting holes at both ends of the outer periphery of the take-up shaft, and the power cord located between the limiting holes is inserted between the arc-shaped limiting plate and the inner wall of the take-up shaft.
[0011] In some embodiments, corresponding through holes are provided at both ends of the outer periphery of the mounting housing, and both ends of the power cord pass through the through holes and are located outside the mounting housing.
[0012] In some embodiments, a limiting sleeve is fixedly installed at the connection between the power cord and the through hole, and a first plug is fixedly installed at one end of the power cord, and a second plug is fixedly installed at the other end of the power cord.
[0013] In some embodiments, a plug cover is further provided at the output end of the first plug.
[0014] In some embodiments, the fixing mechanism includes a compression spring, a connecting column, an adapter, a connecting cylinder, and a pressing cylinder.

Detailed Implementation
[0023] Based on this, in order to improve the problem that when storing power cords in related technologies, the power cord is usually wrapped around the outside of the power plug, but it cannot be fixed after wrapping and will still come loose, affecting the user's storage. In addition, the length of the power cord is fixed, and when the appliance is close to the socket, there will be excess wires exposed. The excess wires will be placed in a disorderly manner, affecting the aesthetics of the overall environment. The embodiments of this application provide the following solutions.
[0024] Please see Figures 1 to 5 A plug cord that is easy to store includes a mounting shell 1, a power cord 2, a winding mechanism 3, and a fixing mechanism 4. The mounting shell 1 is used to support and store the power cord 2, the winding mechanism 3, and the fixing mechanism 4. The winding mechanism 3 is used to wind and unwind the power cord 2. The fixing mechanism 4 is used to fix the winding shaft 31.
[0025] Please see Figures 1 to 3The power cord 2 is wound inside the mounting housing 1 via a winding mechanism 3. The winding mechanism 3 includes a winding shaft 31, a spring 32, a fixing post 33, and an arc-shaped limiting plate 34. The fixing post 33 is fixedly connected to the bottom of the mounting housing 1. The winding shaft 31 is sleeved on the outer periphery of the fixing post 33, and the winding shaft 31 is rotatably connected to the fixing post 33. The arc-shaped limiting plate 34 is fixedly installed inside the winding shaft 31, and the arc-shaped limiting plate 34 is located close to the inner wall of the arc-shaped limiting plate 34. The spring 32 is wound around the inner periphery of the winding shaft 31. One end of the spring 32 is connected to the fixed post 33, and the other end of the spring 32 is fixedly connected to the outer periphery of the winding shaft 31. The outer periphery of the winding shaft 31 is evenly provided with a plurality of limiting holes 5 along the circumferential direction. A middle section of the power cord 2 is inserted into the corresponding limiting holes 5 at both ends of the outer periphery of the winding shaft 31, and the power cord 2 located between the limiting holes 5 is inserted between the arc-shaped limiting plate 34 and the inner wall of the winding shaft 31. The two ends of the outer periphery of the mounting shell 1 are provided with corresponding through holes 6, and the two ends of the power cord 2 pass through the through holes 6 and are located outside the mounting shell 1.
[0026] With this setup, when using the plug cord, the user first pulls the first plug 8 and the second plug 9 at both ends of the mounting housing 1 in opposite directions according to the desired length of the power cord 2. During the pulling of the power cord 2, the winding shaft 31 inside the mounting housing 1 will start to rotate under the force generated by the pulling of the power cord 2, thereby causing the spring 32 on the inner circumference of the winding shaft 31 to gradually retract towards the fixing post 33. When the plug cord is not in use, the fixing of the power cord 2 is released, and the power cord 2 will be wound back to the outer circumference of the winding shaft 31 under the pulling force generated by the spring 32 returning to its original state, thereby storing and fixing the power cord 2.
[0027] The effect of this setup is that when the power cord 2, which is wound around the outer circumference of the take-up spool 31, is pulled during use, the power cord 2 will be slowly released from the outer circumference of the take-up spool 31. At the same time, the spring 32, which is wound around the inner circumference of the take-up spool 31, will slowly tighten towards the fixing post 33 as the take-up spool 31 rotates. When it is not in use, the power cord 2 will be wound back around the outer circumference of the take-up spool 31 under the tension generated by the spring 32 returning to its original state. This will store and fix the power cord 2, preventing it from unraveling and affecting the user's storage. At the same time, the power cord 2 will be wound inside the mounting housing 1, preventing it from being exposed to the outside when not in use, which could lead to accidental damage to the power cord 2 and affect the use of the plug.
[0028] Please see Figures 3 to 5The fixing mechanism 4 includes a compression spring 41, a connecting post 42, an adapter 43, a connecting cylinder 45, and a pressing cylinder 44. The bottom of the take-up shaft 31 has an insertion hole 11. The connecting post 42 is slidably connected within the insertion hole 11. The compression spring 41 is sleeved on the end of the connecting post 42 near the insertion hole 11, and multiple limiting blocks 12 are evenly arranged on the outer periphery of the end of the connecting post 42 near the compression spring 41. The adapter 43 is sleeved on the end of the connecting post 42 away from the compression spring 41, and multiple limiting blocks 12 are evenly arranged on the outer periphery of the adapter 43 away from the limiting blocks. A plurality of snap-fit blocks 18 are evenly arranged at one end of the 12. The bottom of the connecting cylinder 45 is snapped onto the plurality of snap-fit blocks 18. A plurality of sliders 13 are evenly arranged on the outer periphery of the connecting cylinder 45. A plurality of sliding grooves 14 are evenly opened on the outer periphery of the pressing cylinder 44. The plurality of sliders 13 are slidably connected in the plurality of sliding grooves 14. A plurality of inclined slots 15 are evenly opened on the outer periphery of the pressing cylinder 44 near the sliding grooves 14. An installation cylinder 16 is also sleeved on the outer periphery of the pressing cylinder 44. A plurality of teeth 17 are evenly opened on the end of the connecting cylinder 45 near the adapter 43.
[0029] With this configuration, when fixing the take-up shaft 31, pressing the pressing cylinder 44 causes the sliding groove 14 on the outer periphery of the pressing cylinder 44 to slide and connect with the slider 13 on the outer periphery of the connecting cylinder 45 until the slider 13 abuts against one end inside the sliding groove 14. This causes the pressing cylinder 44 to move the connecting cylinder 45 downward, so that the teeth 17 at the bottom of the connecting cylinder 45 abut against the limiting block 12 on the adapter 43. Subsequently, the pressing cylinder 44 continues to move downward under pressure. During the movement of the pressing cylinder 44... The top of the pressing cylinder 44 presses the connecting post 42 downward, causing the connecting post 42 to enter the insertion hole 11 and limit and fix the rotating shaft. At the same time, during the movement of the connecting post 42, the limiting block 12 on the connecting post 42 compresses the compression spring 41, causing the compression spring 41 to deform. When the bottom of the pressing cylinder 44 moves to the bottom of the locking block 18, the adapter 43 rotates to lock the inclined slot 15 into the bottom of the locking block 18, thereby completing the fixation of the winding shaft 31.
[0030] When the plug cord is no longer needed, press the cylinder 44 again to rotate the adapter 43 so that the slanted slot 15 is misaligned with the snap block 18. At this time, under the force generated by the spring returning to its original state, the connecting post 42 in the plug hole 11 will be brought out, causing the winding shaft 31 to continue to rotate, and the stretched power cord 2 will be wound up again to the outer circumference of the winding shaft 31, thus completing the storage of the power cord 2.
[0031] The effect of this setup is that, through the coordinated arrangement of the compression spring 41, connecting post 42, adapter 43, connecting cylinder 45, and pressing cylinder 44, the power cord 2 can be stretched to a suitable length. Then, by pushing the pressing cylinder 44 downwards, the connecting post 42 is inserted into the insertion hole 11, limiting and fixing the winding shaft 31 to prevent further rotation. This secures the power cord 2 around the winding shaft 31, preventing excess wire from protruding and being disorderly placed, thus affecting the overall aesthetics. Adjusting the power cord 2 to a suitable length also facilitates the use and connection of the plug, further improving the practicality of the plug.
[0032] As can be seen from the above, the working principle of this application is as follows:
[0033] When using the plug cord, the user first pulls the first plug 8 and the second plug 9 at both ends of the mounting shell 1 in opposite directions according to the length of the power cord 2 to be used. During the pulling of the power cord 2, the winding shaft 31 inside the mounting shell 1 will start to rotate under the force generated by the pulling of the power cord 2, so that the spring 32 on the inner circumference of the winding shaft 31 will gradually retract towards the fixing post 33. When the plug cord is not in use, the fixing of the power cord 2 is released. Under the tension generated by the spring 32 returning to its original state, the power cord 2 will be wound back to the outer circumference of the winding shaft 31, thereby storing and fixing the power cord 2.
[0034] When fixing the take-up shaft 31, by squeezing the pressing cylinder 44, the sliding groove 14 on the outer periphery of the pressing cylinder 44 is slidably connected to the slider 13 on the outer periphery of the connecting cylinder 45 until the slider 13 abuts against one end inside the sliding groove 14, thereby causing the pressing cylinder 44 to drive the connecting cylinder 45 to move downward, so that the teeth 17 at the bottom of the connecting cylinder 45 abut against the limiting block 12 on the adapter 43. Then the pressing cylinder 44 continues to move downward under pressure. During the movement of the pressing cylinder 44, the pressing cylinder... The top of 44 will press the connecting post 42 downward, so that the connecting post 42 enters the insertion hole 11 and limits and fixes the rotating shaft. At the same time, during the movement of the connecting post 42, the limiting block 12 on the connecting post 42 compresses the compression spring 41, causing the compression spring 41 to deform. When the bottom of the pressing cylinder 44 moves to the bottom of the snap-fit block 18, the adapter 43 rotates so that the inclined slot 15 snaps and fixes with the bottom of the snap-fit block 18, thereby completing the fixation of the winding shaft 31.
[0035] When the plug cord is no longer needed, press the cylinder 44 again to rotate the adapter 43 so that the slanted slot 15 is misaligned with the snap block 18. At this time, under the force generated by the spring returning to its original state, the connecting post 42 in the plug hole 11 will be brought out, causing the winding shaft 31 to continue to rotate, and the stretched power cord 2 will be wound up again to the outer circumference of the winding shaft 31, thus completing the storage of the power cord 2.
[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
