Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, and specifically relates to an adjustable power adapter. Background Technique

[0002] A power adapter is a power supply conversion device for small portable electronic devices and electrical appliances. It generally consists of components such as a shell, a transformer, an inductor, a capacitor, a control IC, and a PCB board. The length of the cable of the power adapter is usually fixed. When using the power adapter at a short distance, the redundant cable length not only affects the use experience of the power adapter, but also the too long cables will knot with each other, resulting in damage to the cables. Therefore, an adjustable power adapter is needed. So, the existing adjustable power adapters have been continuously innovated and developed. It can be seen that the current adjustable power adapters basically meet people's needs, but there are still some problems.

[0003] For example, the patent document with the publication number of CN212571581 U discloses a desktop power adapter with adjustable cable length, including a device main body, a sliding plate, and a second screw cap. The device main body is in a cuboid structure, and a transformer is arranged inside the device main body. One side of the device main body is provided with a power cord extending out of the device main body, and a plug is arranged at the end of the power cord away from the device main body.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1 , Figure 5 and Figure 8 , an adjustable power adapter: including a first housing 1, one side of the inner wall of the first housing 1 is fixedly connected with an electronic component assembly 2, one side of the electronic component assembly 2 is electrically connected with a first cable 3, one end of the first cable 3 is electrically connected with a plug 4, the other side of the electronic component assembly 2 is electrically connected with a second cable 5, and the top of the first housing 1 is lapped with a second housing 22;

[0029] A winding structure, including a winding shaft 6, the inner bottom wall of the first housing 1 is rotatably connected with a winding shaft 6, and one side of the middle part of the second cable 5 is fixedly connected to the surface of the winding shaft 6. One side of the bottom of the winding shaft 6 is fixed with a spring piece 7, and the other end of the spring piece 7 is fixedly connected to the inner bottom wall of the first housing 1. A tooth pattern 8 is provided in the middle of the inner wall of the winding shaft 6. The inner top wall of the first housing 1 is fixedly connected with a telescopic rod 9. The inner wall of the telescopic rod 9 is lapped with a first spring 10. The top end of the telescopic rod 9 is fixedly connected with a connecting rod 11.

The surface of the clamping strip 12 is lapped on the inner wall of the tooth pattern 8.

[0030] When a adjustable power adapter is needed, first insert the plug 4 into the socket, and then pull the second cable 5. Since the second cable 5 is wound around the surface of the cable take-up reel 6, when pulling the cable take-up reel 6, it drives the cable take-up reel 6 to rotate inside the first housing 1, so as to draw out the second cable 5 from the first housing 1. After pulling the second cable 5 to an appropriate length, push the latch 12 to rotate through the second spring 13, so that the latch 12 is engaged into the tooth pattern 8, thereby fixing the cable take-up reel 6, and then use the second cable 5. After use, press the connecting rod 11, and the downward movement of the connecting rod 11 presses the telescopic rod 9. The telescopic rod 9 can only move up and down. The downward movement of the connecting rod 11 drives the latch 12 to move downward, so as to move to the bottom of the tooth pattern 8, releasing the fixation of the cable take-up reel 6. Then, drive the cable take-up reel 6 to rotate counterclockwise by the elastic force of the spring piece 7, so as to wind up the second cable 5. After winding the second cable 5 onto the surface of the cable take-up reel 6, the connector at one end of the second cable 5 is stuck outside the first housing 1, and then release the connecting rod 11.

[0034] One end of the second cable 5 can move in the wire groove 17, and the surfaces of the blocks 19 on both sides of the connecting rod 11 are lapped in the activity groove 20, thereby restricting the maximum and minimum positions of the lifting of the blocks 19, and thus restricting the lifting position of the connecting rod 11.

[0035] Please refer to Figure 2 , Figure 5 and Figure 6, the spring piece 7 is in a coiled shape. One end of the inner wall and one end of the outer side of the spring piece 7 are respectively connected to the inner wall of the take-up reel 6 and the inner bottom wall of the first housing 1. Limit grooves 15 are provided at the tops on both sides of the first housing 1. Two sides of the bottom of the second housing 22 are fixedly connected with limit blocks 16, and the surfaces of the limit blocks 16 are lapped on the inner walls of the limit grooves 15.

[0036] The spring piece 7 is in a coiled shape and can drive the take-up reel 6 to rotate. When it is necessary to repair the equipment, first press the limit block 16 and press the limit block 16 into the first housing 1, and then remove the second housing 22 from the top of the first housing 1. After the repair, snap the limit block 16 into the limit groove 15 to fix the first housing 1 and the second housing 22.

[0037] Working principle: When using an adjustable power adapter, first insert the plug 4 into the socket, so that the first cable 3 is conducted to the second cable 5 through the electronic component assembly 2, then pull the second cable 5 and pull the second cable 5 from the surface of the take-up reel 6 to the outside of the first housing 1, and then use the second cable 5 to snap the clamping strip 12 into the tooth pattern 8 to fix the take-up reel 6. After use, press the connecting rod 11 to make the spring piece 7 drive the take-up reel 6 to rotate, so as to wind up the second cable 5 and wind up the second cable 5 into the first housing 1.
