[0017] The step S1: by sliding the handle outward at the same time, the fixing of the sliding rack to the gear is released, so that the sliding gear can slide with the adapter, and then the adapter is slid out of the inner cavity of the protective shell; when the handle is released, the fixing component drives the sliding rack to engage with the gear, and the interaction between the sliding rack, the gear and the fixed rack can fix the position of the gear, and then the position of the adapter is fixed.

[0018] Step S2: Rotate the knob so that the knob drives the screw to rotate. Under the interaction between the screw and the slider, the slider drives the connecting rod and the clamping plate to slide outward along the second sliding direction under the limiting action of the limiting assembly, so that the clamping plate no longer fixes the wire harness storage assembly.

[0019] The step S3: by pulling the pull ring, under the action of the telescopic assembly, the fixed column, the blocking plate and the wire harness wound and stored on the fixed column can be taken out, thereby facilitating the connection of the power supply.

[0020] Step S4: plug the plug on the adapter into the power socket, and then connect the wiring harness to the electrical device that needs to be charged, and then the charging operation can be performed.

[0021] The main body of the present invention has the following beneficial effects:

[0022] Firstly, by setting the fixed column and the blocking plate, the wiring harness of the adapter can be stored and wound in an orderly manner on the outer wall of the fixed column to realize the storage of the wiring harness; by setting the sliding component, the blocking plate, the fixed column and the wiring harness wound and stored on the fixed column can be stably fixed in the inner cavity of the storage box to avoid the wiring harness becoming loose on the fixed column; by setting the position adjustment component, the position of the adapter can be adjusted; when carrying it outside, the adapter can be stored in the inner cavity of the protective shell to realize the protection of the adapter, avoid deformation of the plug, and extend the service life of the adapter.

[0023] Secondly, by rotating the knob, the knob drives the screw to rotate. Under the action of the relative thread rotation force of the outer wall of the screw relative to the thread, when the screw rotates, the two sliders can slide outward at the same time under the limiting action of the limiting groove and the limiting block, and then the two sliders drive the two connecting rods and the clamping plate to slide outward along the two first slideways respectively, thereby releasing the clamping plate from fixing the blocking plate and the fixed column, so that the blocking plate and the fixed plate can be pulled out of the inner cavity of the storage box, which is convenient for the storage and removal of the wire harness.

[0024] Thirdly, by pulling the pull ring, the pull ring drives the blocking plate, the fixed column and the inner cavity for sliding and storing the wire harness, and the telescopic rod can also be extended out of the inner cavity of the telescopic tube, so that the first spring undergoes elastic deformation and generates corresponding elastic force. At this time, the wire harness can be taken out. After the wire harness is taken out, the pull ring is released. Under the elastic pulling force of the first spring, the blocking plate and the fixed column can be retracted to the inner cavity for storage. With the cooperation of the telescopic rod, the telescopic tube and the first spring, the fixed column can also be stably retracted in the inner cavity of the storage box when storing the wire harness.

[0025] Fourthly, by pulling the two handles outward at the same time, the handles drive the moving block to slide outward, thereby increasing the distance between the bottom ends of the first connecting rod and the second connecting rod, and causing the second spring to be compressed and elastically deformed, thereby generating a corresponding elastic force. Since the length of the first connecting rod is fixed to the length of the second connecting rod, when the distance between the bottom ends of the first connecting rod and the second connecting rod increases, the distance between the top ends of the first connecting rod and the second connecting rod also increases, thereby reducing the distance between the sliding rack and the fixed plate, causing the gear to be separated from the fixing of the sliding rack to the gear. At this time, the adapter is pulled to pull the adapter out of the fixing plate. The protective shell, under the action of the fixed rack, when the adapter slides, the gear can rotate. When the adapter slides out to a suitable length, the handle is released, so that the two moving blocks slide quickly inward under the elastic force of the second spring, thereby reducing the distance between the bottom ends of the first connecting rod and the second connecting rod, so that the sliding rack is away from the fixed plate and meshes with the gear, so that the gear does not rotate, thereby stably fixing the adapter in a position, making it convenient to use and store the adapter, avoiding bending and deformation of the plug, and extending the service life of the adapter and the plug.

One end of the first spring 11 is fixedly installed in the inner chamber of the telescopic chamber 8, and the other end of the first spring 11 is fixedly installed on the inner wall of the storage box 4.

[0042] It should be noted that by pulling the pull ring 34, the pull ring 34 drives the blocking plate 7, the fixed column 6 and the inner cavity for sliding and storing the wiring harness, and the telescopic rod 10 can also be extended out of the inner cavity of the telescopic tube 9, so that the first spring 11 undergoes elastic deformation and generates corresponding elastic force. At this time, the wiring harness can be taken out. After the wiring harness is taken out, the pull ring 34 is released. Under the elastic pulling force of the first spring 11, the blocking plate 7 and the fixed column 6 can be retracted to the inner cavity for storage. With the cooperation of the telescopic rod 10, the telescopic tube 9 and the first spring 11, the fixed column 6 can also be stably retracted in the inner cavity of the storage box 4 when storing the wiring harness.

[0043] As a preferred solution, further, the sliding assembly includes a screw 12, a knob 13, a slider 14, a first slide 15, a moving rod 16, a splint 17 and a limit assembly. The bottom end of the screw 12 is rotatably connected to the bottom end of the slide box through a bearing, the top end of the screw 12 extends to the top end of the slide box 3, the knob 13 is interference fit on the top end of the screw 12, the two first slides 15 are respectively opened on the upper and lower sides of the right end of the outer wall of the slide box 3, the two sliders 14 are respectively screwed on the upper and lower sides of the outer wall of the screw 12, one end of the two moving rods 16 are respectively fixedly mounted on the left side of the outer wall of the two sliders 14, the other ends of the two moving rods 16 respectively pass through the inner cavity of the two first slides 15 and extend to the right side of the outer wall of the slide box 3, the two splints 17 are respectively fixedly mounted on the other ends of the two moving rods 16, and the two sliders 14 are movably connected to the slide box 3 through the limit assembly.

[0044] It should be noted that by rotating the knob 13, the knob 13 drives the screw 12 to rotate. Under the action of the relative thread rotation force of the outer wall of the screw 12 relative to the thread, when the screw 12 rotates, the two sliders 14 can slide outward at the same time under the limiting action of the limit groove 19 and the limit block 18, and then the two sliders 14 drive the two connecting rods and the clamping plate 17 to slide outward along the two first slideways 15 respectively, thereby releasing the fixation of the clamping plate 17 to the blocking plate 7 and the fixing column 6, so that the blocking plate 7 and the fixing plate 25 can be pulled out of the inner cavity of the storage box 4, which is convenient for the storage and removal of the wiring harness, and the blocking plate 7, the fixing column 6 and the wiring harness wound and stored on the fixing column 6 are stably fixed in the inner cavity of the storage box 4, avoiding the wiring harness from becoming loose on the fixing column 6.

[0045] As a preferred embodiment, further, each position adjustment component includes a second slide 20, a rotating column 21, a gear 22, a fixed rack 23, a sliding rack 24 and a fixed component. The second slide 20 is opened on the outer wall of the protective shell 2, one end of the rotating column 21 is rotatably connected to the outer wall of the adapter 1 through a bearing, and the other end of the rotating column 21 passes through the inner cavity of the second slide 20 and extends to the outer wall of the protective shell 2. The gear 22 is interference fit on the outer wall of the rotating column 21, the fixed rack 23 is arranged on the outer wall of the protective shell 2, the fixed component is arranged on the outer wall of the protective shell 2, the fixed rack 23 is meshed with the gear 22, and the sliding rack 24 is connected to the protective shell 2 through the fixed component.

[0046] It should be noted that, through the mutual cooperation between the fixed rack 23 and the gear 22, when the adapter 1 is moved, the gear 22 can be rotated. In the setting of the fixed component, the sliding rack 24 can be engaged with the gear 22, and then under the interaction between the gear 22 and the sliding rack 24 and the fixed rack 23, the gear 22 will not rotate, thereby stably fixing the position of the adapter 1, making it convenient to adjust the position of the adapter 1.

[0047] As a preferred solution, further, a pull ring 34 is provided on the right side of the outer wall of the blocking member located on the right side of the outer wall of the fixing column 6, and an anti-slip edge is provided on the outer wall of the pull ring 34.

[0048] It should be noted that, through the provision of the pull ring 34, the blocking plate 7 and the fixing column 6 can be driven by the pull ring 34 to slide out of the inner cavity of the storage box 4, thereby facilitating the removal and storage of the wire harness.

[0049] As a preferred solution, further, the limit assembly includes a limit slot 19 and a limit block 18. The limit slot 19 is opened on the left side of the inner cavity of the sliding box 3. One ends of the two limit blocks 18 can be slidably embedded in the upper and lower sides of the inner cavity of the limit slot 19, and the other ends of the two limit blocks 18 are fixedly connected to the two sliders 14 respectively.

[0050] It should be noted that, by setting the limit groove 19 and the limit block 18, the slider 14 can be prevented from rotating with the screw 12 when the screw 12 rotates, thereby improving the stability of the sliding assembly. The inner cavity of the limit groove 19 and the outer wall of the limit block 18 are both in a "T" shape, which allows the limit block 18 to be stably embedded in the inner cavity of the limit groove 19, thereby improving the stability of the limit assembly.

[0051] As a preferred solution, further, the fixing assembly includes a fixing plate 25, a baffle 26, a guide rod 27, a fixing block 28, a moving block 29, a second spring 30, a first connecting rod 31, a second connecting rod 32 and a handle 33. The fixing plate 25 is fixedly mounted on the outer wall of the protective shell 2. The four baffles 26 are respectively arranged in two groups on the left and right sides of the bottom end of the sliding rack 24 and on the left and right sides of the top end of the fixing plate 25. The two guide rods 27 are respectively fixedly mounted on the inner sides of the two groups of baffles 26. The two fixing blocks 28 are fixedly mounted on the top end of the fixing plate 25 and the bottom end of the sliding rack 24. The two fixing blocks 28 are respectively fixedly sleeved on the two In the middle of the outer wall of the guide rod 27, four moving blocks 29 are slidably adjusted in groups of two on the left and right sides of the outer walls of the two guide rods 27, and two second springs 30 are respectively sleeved on the left and right sides of the outer wall of the guide rod 27 located below, and the upper and lower ends of the first connecting rod 31 are respectively rotatably connected to the outer walls of the two moving blocks 29 through pins, and the upper and lower ends of the second connecting rod 32 are respectively rotatably connected to the outer walls of the two moving blocks 29 through pins, and the middle parts of the first connecting rod 31 and the second connecting rod 32 are rotatably connected through pins, and two handles 33 are respectively fixedly mounted on the front ends of the two moving blocks 29 located below, and the outer walls of the handles 33 are provided with anti-slip edges.

[0052] It should be noted that by pulling the two handles 33 outward at the same time, the handles 33 drive the moving block 29 to slide outward, thereby increasing the distance between the bottom ends of the first connecting rod 31 and the second connecting rod 32, and compressing the second spring 30 to elastically deform, thereby generating a corresponding elastic force. Since the length of the first connecting rod 31 is fixed to the length of the second connecting rod 32, when the distance between the bottom ends of the first connecting rod 31 and the second connecting rod 32 increases, the distance between the top ends of the first connecting rod 31 and the second connecting rod 32 also increases, thereby reducing the distance between the sliding rack 24 and the fixing plate 25, and causing the gear 22 to be separated from the fixing of the sliding rack 24 to it. At this time, the adapter 1 is pulled so that the adapter 1 pulls out the protective shell 2, and under the action of the fixed rack 23, when the adapter 1 slides, the gear 22 can rotate. When the adapter 1 slides out to a suitable length, the handle 33 is released, so that the two moving blocks 29 slide quickly inward under the elastic force of the second spring 30, thereby reducing the distance between the bottom ends of the first connecting rod 31 and the second connecting rod 32, so that the sliding rack 24 is away from the fixed plate 25 and meshes with the gear 22, so that the gear 22 does not rotate, thereby stably fixing the adapter 1 in a position, making it convenient to use and store the adapter 1, avoiding bending and deformation of the plug 5, and extending the service life of the adapter 1 and the plug 5.

[0053] As a preferred solution, further, the sliding rack 24 can be engaged with the gear 22. With the cooperation of the fixed rack 23, the gear 22 will not rotate when the sliding rack 24 is engaged with the gear 22, thereby fixing the position of the adapter 1 and enabling the adapter 1 to be stably stored in the inner cavity of the protective shell 2, thereby extending its service life.

[0054] As a preferred solution, further, the threads on the left and right sides of the outer wall of the screw rod 12 are arranged in opposite directions, so that the screw rod 12 can generate rotational forces in opposite directions when rotating, thereby allowing the two sliders 14 to slide inward or outward at the same time.

[0055] A charging method for a portable power adapter 1, comprising the following steps: step S1, taking out the adapter 1, step S2, releasing the fixation, step S3, taking out the wiring harness, step S4, connecting the adapter 1;

[0056] Step S1: By sliding the handle 33 outward at the same time, the fixing of the sliding rack 24 on the gear 22 is released, so that the sliding gear 22 can slide with the adapter 1, and then the adapter 1 is slid out of the inner cavity of the protective shell 2. After loosening the handle 33, the fixing component drives the sliding rack 24 to engage with the gear 22. Under the interaction between the sliding rack 24, the gear 22 and the fixed rack 23, the position of the gear 22 can be fixed, and then the position of the adapter 1 is fixed.

[0057] Step S2: Rotate the knob 13 so that the knob 13 drives the screw 12 to rotate. Under the interaction between the screw 12 and the slider 14, the slider 14 can drive the connecting rod and the clamping plate 17 to slide outward along the second sliding direction under the limiting action of the limiting assembly, so that the clamping plate 17 no longer fixes the wire harness storage assembly.

[0058] Step S3: By pulling the pull ring 34, under the action of the telescopic assembly, the fixed column 6, the blocking plate 7 and the wire harness wound and stored on the fixed column 6 can be taken out, thereby facilitating the connection of the power supply.

[0059] Step S4: Plug the plug 5 on the adapter 1 into the power socket, and then connect the wiring harness to the electrical device to be charged, and then the charging operation can be carried out.

[0060] It should be noted that when working, first, rotate the knob 13 so that the knob 13 drives the screw 12 to rotate. Under the action of the relative thread rotation force of the outer wall of the screw 12 relative to the thread, when the screw 12 is rotating, the two sliders 14 can slide outward at the same time under the limiting action of the limiting groove 19 and the limiting block 18, and then the two sliders 14 drive the two connecting rods and the clamping plate 17 to slide outward along the two first slideways 15 respectively, thereby releasing the clamping plate 17 from fixing the blocking plate 7 and the fixing column 6, so that the blocking plate 7 and the fixing plate 25 can be pulled out of the inner cavity of the storage box 4, which is convenient for the storage and removal of the wiring harness. At this time, pull The pull ring 34 is moved to make the pull ring 34 drive the blocking plate 7, the fixed column 6 and the inner cavity for sliding and storing the wire harness, and the telescopic rod 10 can also be extended out of the inner cavity of the telescopic tube 9, so that the first spring 11 is elastically deformed and generates a corresponding elastic force. At this time, the wire harness can be taken out. After the wire harness is taken out, the pull ring 34 is released. Under the elastic pulling force of the first spring 11, the blocking plate 7 and the fixed column 6 can be retracted to the inner cavity for storage. With the cooperation of the telescopic rod 10, the telescopic tube 9 and the first spring 11, the fixed column 6 can be stably retracted in the inner cavity of the storage box 4 when storing the wire harness. Next, the two handles 33 are pulled outward at the same time. The handle 33 drives the moving block 29 to slide outward, thereby increasing the distance between the bottom ends of the first connecting rod 31 and the second connecting rod 32, and compressing the second spring 30 to produce elastic deformation, thereby generating a corresponding elastic force. Since the length of the first connecting rod 31 is fixed to the length of the second connecting rod 32, when the distance between the bottom ends of the first connecting rod 31 and the second connecting rod 32 increases, the distance between the top ends of the first connecting rod 31 and the second connecting rod 32 also increases, thereby reducing the distance between the sliding rack 24 and the fixing plate 25, so that the gear 22 is separated from the fixing of the sliding rack 24. At this time, the adapter 1 is pulled out of the protective shell 2, and the adapter 1 is fixed. Under the action of the rack 23, when the adapter 1 slides, the gear 22 can rotate. When the adapter 1 slides out to a suitable length, the handle 33 is released, so that the two moving blocks 29 slide quickly inward under the elastic force of the second spring 30, thereby reducing the distance between the bottom ends of the first connecting rod 31 and the second connecting rod 32, so that the sliding rack 24 is away from the fixed plate 25 and meshes with the gear 22, so that the gear 22 does not rotate, thereby stably fixing the adapter 1 in a position, making it convenient to use and store the adapter 1, avoiding bending and deformation of the plug 5, and extending the service life of the adapter 1 and the plug 5.
