Technical Field
[0001] The utility model relates to the technical field of power adapters, in particular to a foldable adapter. Background Art
[0002] A power adapter is a power conversion device that powers small portable electronic devices and electronic appliances. The voltage of the power grid is usually 110V, 220V, 380V, etc., while the power supply voltage of common electronic products is usually below 100V or even below 20V. If it is directly connected to the power grid, it is easy to cause the equipment to burn out. Therefore, it is necessary to use an adapter for voltage conversion. The adapter can also convert AC power into DC power, which is convenient for charging the batteries of electronic products.
[0003] A foldable plug adapter with application number 202321711207.0, the foldable plug is electrically connected through a spring clip. When not in use, the plug is accommodated in a folding groove. When in use, the plug is rotated to extend vertically. At this time, the contact of the plug abuts the deformed part of the spring clip, the deformed part deforms and generates a restoring force, so that the friction between the rotating connector of the plug and the limit hole also increases accordingly. The posture stability of the plug can be maintained by the shape of the folding groove on the one hand, and enhanced by the increase in friction on the other hand.
[0004] The foldable adapters currently on the market are usually similar to the above-mentioned technical solutions, where the plug can be rotated 90 degrees and retracted into the adapter housing. There is also an adapter that uses a sliding method to retract the plug into the adapter housing. Regardless of whether it is folded or slid, at least one side of the plug will be exposed after being retracted into the adapter housing, causing the plug to still be easily affected by water and dust. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide a foldable adapter to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable adapter, comprising an adapter body, a swing arm connected to one side of the inside of the adapter body, and a torsion spring connected between the swing arm and the adapter body, a plug connected to one side of the inside of the swing arm, and a first spring connected to the inside of the plug, one end of the first spring is connected to a support plate, and a first carbon brush plate is fixed to one side of the support plate, and a second carbon brush plate is fixed to the inside of the adapter body.
[0007] By adopting the above technical solution, the plug is first facing downward or upward by rotating the swing arm upward and then rotating the plug half a circle, and then the swing arm is driven by the torsion spring to reverse and reset, and the inner wall of the adapter body is cooperated to limit the plug to prevent the plug from swinging left and right. If the plug is facing downward at this time, the first carbon brush plate and the second carbon brush plate are tightly fitted together by the first spring and the support plate, which is convenient for connecting to the power socket for power supply. If the plug is facing upward at this time, the terminals of the plug are shielded by the cooperation of the adapter body, the swing arm and the shell of the plug.
[0008] Furthermore, the plug is rotatably connected to the swing arm, and the swing arm is rotatably connected to the adapter body.
[0009] By adopting the above technical solution, the user rotates the swing arm upward, at which time the torsion spring is compressed. The user then rotates the plug half a circle to make the plug face downward or upward. The torsion spring then drives the swing arm to reverse and reset to cooperate with the inner wall of the adapter body to limit the plug.
[0010] Furthermore, the support plate is slidably connected to the plug.
[0011] By adopting the above technical solution, the first spring pushes the support plate to move toward the second carbon brush plate. Since the first carbon brush plate is fixed to one side of the support plate, the support plate moves toward the second carbon brush plate and resists against it.
[0012] Furthermore, the first carbon brush plate abuts against the second carbon brush plate.
[0013] By adopting the above technical solution, the first carbon brush plate and the second carbon brush plate are closely fitted together through the first spring and the support plate, which is convenient for connecting to a power socket for power supply.
[0014] Furthermore, one side of the adapter body is connected to a shell, and a conductive slip ring is installed inside the shell, one side of the conductive slip ring is connected to a wire reel, and a clockwork spring and a ratchet are respectively sleeved on the outside of the wire reel, a pawl passes through one side of the shell, and a second spring is connected between the pawl and the shell.
[0015] By adopting the above technical solution, after inserting the plug into the power socket, the user pulls the power cord to pull the power cord out of the housing. At this time, the wire reel is forced to rotate to compress the spring and drive the ratchet to rotate. At this time, the second spring causes the pawl to automatically approach the ratchet and resist it, preventing the spring from driving the wire reel to reverse and retract the power cord. When use is finished, the user only needs to turn the pawl to end the limitation of the ratchet. At this time, the spring spring drives the wire reel to reverse and rewind the power cord, reducing the occurrence of power cord entanglement and bending.
[0016] Furthermore, a power cord is wound around the outer ring of the take-up reel.
[0017] By adopting the above technical solution, the winding reel is driven by the clockwork spring to reverse and wind up the power cord, thereby reducing the phenomenon of the power cord being entangled and bent.
[0018] Furthermore, the power line, the conductive slip ring, the second carbon brush plate and the first carbon brush plate are all electrically connected to the plug.
[0019] By adopting the above technical solution, after being inserted into the power socket, the current passes through the plug, the first carbon brush plate, the second carbon brush plate, and the conductive slip ring in sequence into the power cord, and then enters the electronic product for power supply or charging.
[0020] Furthermore, the pawl is rotatably connected to the housing, and the pawl abuts against the ratchet wheel.
[0021] By adopting the above technical solution, the second spring makes the pawl automatically approach the ratchet wheel and abut against it, thereby preventing the clockwork spring from driving the take-up reel to reverse and retract the power cord.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model arranges a swing arm, a plug, a first spring, a first carbon brush plate, a second carbon brush plate and a torsion spring. First, the swing arm is rotated upward and then the plug is rotated half a circle to make the plug face downward or upward. Then, the torsion spring drives the swing arm to reverse and reset, and cooperates with the inner wall of the adapter body to limit the plug to prevent the plug from swinging left and right. If the plug faces downward at this time, the first carbon brush plate and the second carbon brush plate are tightly fitted together by the first spring and the support plate, which is convenient for connecting to the power socket for power supply. If the plug faces upward at this time, the adapter body, the swing arm and the shell of the plug cooperate to shield the terminals of the plug, effectively reducing the occurrence of water and dust contacting the terminals of the plug.

[0037] See also Figure 1In the above embodiment, a housing 9 is connected to one side of the adapter body 1, a conductive slip ring 16 is installed inside the housing 9, and the conductive slip ring 16 is electrically connected to the plug 3 to prevent the take-up reel 10 from rotating and causing the power cord 11 to be twisted off; a take-up reel 10 is connected to one side of the conductive slip ring 16, and the power cord 11 is wound around the outer ring of the take-up reel 10.
