Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a wall-plug-type power adapter which is easy to plug and unplug. Background Art

[0002] In order to make the connection between the socket and the adapter plug more stable, the existing socket often makes the gap between the two springs in the socket smaller, which will cause the plug and the socket to fit too tightly. When unplugging the plug, you need to use both hands to complete the task of unplugging the plug. Sometimes you need to put down the object while holding it in one hand, which is very troublesome.

[0003] At present, existing adapter plugs are usually provided with textures on the side to increase the friction of the outer wall of the adapter plug, so as to facilitate the user to pick up and plug and unplug; however, if the plug and the socket fit too tightly, it is still necessary to use a large force or use two hands, which is not convenient to pull out; and most adapter plugs have a certain gap between the adapter plug and the socket after being inserted into the socket. If liquid is spilled on the adapter plug, the liquid can easily penetrate into the plug or the socket through the gap between the adapter plug and the socket, thereby causing a short circuit, which has a poor safety problem.

[0004] In view of this, it is indeed necessary to provide a technical solution to the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a wall-plug type power adapter which is easy to plug and unplug, so as to solve the problem that the above adapter is inconvenient for users to unplug when in use and has poor waterproof performance.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A pluggable wall-type power adapter comprises an adapter body, wherein the adapter body has a plug inserted into a socket and a contact surface abutting against the socket, and further comprises:

[0008] There are at least two top plates, which are pivotally connected to the two sides of the adapter body, and one end of the top plate is provided with a slide groove, and the other end can be rotated to the contact surface;

[0009] an elastic member, disposed between the top plate and the adapter body, the elastic member being in a deformed state so that the other end of the top plate is flush with the contact surface;

[0010] The connecting plate has plug-in parts at both opposite ends, which are respectively inserted into the sliding grooves, and the connecting plate has a connecting plane that is flush with the contact surface.

[0011] As an improvement of the wall-plug power adapter, the side of the connecting plate flush with the contact surface is a connecting plane, and the side of the connecting plate away from the adapter body is gradually inclined upward toward the connecting plane to form a first inclined surface.

[0012] As an improvement of the wall-plug power adapter, a partition portion is provided under the connecting plate. After the plug-in portion of the connecting plate is fully inserted into the slide groove, the partition portion fits against the top of the adapter body to separate the gap between the inner side of the connecting plate and the adapter body.

[0013] As an improvement of the wall-plug power adapter, a stopper is provided on at least one side of the adapter body, and the top plate on the same side can be rotated to abut against the stopper, and the stopper is used to limit the rotation range of the top plate.

[0014] As an improvement of the wall-plug power adapter, the plug-in part is provided with an installation groove on at least one side, a positioning block is slidably provided in the installation groove, a return spring is provided between the positioning block and the bottom of the installation groove, and a plurality of positioning grooves are provided on one side wall of the slide groove of the top plate, and the positioning block cooperates with the positioning groove.

[0015] As an improvement of the wall-plug power adapter, at least two side edges of the end of the positioning block are provided with bevels, both forming a second bevel, and the positioning groove matches the shape of the end of the positioning block.

[0016] As an improvement of the wall-plug power adapter, the end of the top plate away from the slide slot is rotatably provided with a roller, and the top plate can be rotated to contact and cooperate with the socket through the roller.

[0017] As an improvement of the wall-plug power adapter, the top plate can be rotatably provided with a rotating shaft, the rotating shaft passes through the top plate and is connected to the adapter body, the elastic member is sleeved on the rotating shaft, a shielding portion is provided at the end of the rotating shaft, and the shielding portion is a cylindrical structure that covers the elastic member.

[0018] As an improvement of the wall-plug power adapter, the elastic member is a torsion spring.

[0019] Compared with the prior art, the technical effects of the utility model are:

[0020] The top plate of the utility model cooperates with the connecting plate to form a lever structure, and the reaction force generated by the top plate squeezing the socket drives the plug of the adapter body to be pulled out from the socket, thereby preventing the socket from loosening from the wall due to long-term plugging and unplugging of the plug and the socket, and also makes it easier to pull out the plug.

[0021] The plug of the power adapter is inserted into the socket, and the connecting plate and the top plate are both in a vertical state. At this time, one side surface of the connecting plate and the contact surface of the adapter body are in contact with the socket. The connecting plate is located on the upper side of the plug and is in a semi-enclosed shape. After being in contact with the socket, the plug part is protected to prevent liquid from penetrating into the plug from the gap between the connecting plate and the socket, avoiding a short circuit between the plug and the socket, and improving the waterproof performance of the power adapter.

[0022] Furthermore, after the connecting plate abuts against the socket, the elastic member is still in a deformed state, providing thrust for the connecting plate, so that the connecting plate can always fit closely with the socket and is not easily affected by external forces.

[0023] The connection plate of the power adapter can pull the connection plate to move upward through the cooperation between the plug-in part and the slide slot, thereby extending the distance between the force point and the fulcrum, thereby achieving the purpose of saving more effort.

[0034] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0035] like Figures 1 to 6 As shown, a pluggable wall-mounted power adapter includes an adapter body, wherein the adapter body 1 has a plug 12 inserted into a socket and a contact surface 11 that fits the socket, and also includes:

[0036] The top plate 2 has at least two parts, which are pivotally connected to the two sides of the adapter body 1, and one end of the top plate 2 is provided with a slide groove 21, and the other end can be rotated to the contact surface 11;

[0037] An elastic member 3 is disposed between the top plate 2 and the adapter body 1, and the elastic member 3 is in a deformed state so that the other end of the top plate 2 is flush with the contact surface 11;

[0038] The connecting plate 4 has plug-in portions 41 at opposite ends, which are respectively inserted into the slide grooves 21 . The connecting plate 4 has a connecting plane 43 that is flush with the contact surface 11 .

[0039] Specifically, the plug 12 is located at the front side of the adapter body 1, and the two top plates 2 are located at the left and right sides of the adapter body 1. The adapter body 1 is rotatably connected to the lower part of the top plate 2. The top plate 2 can be rotated so that the lower end contacts and cooperates with the socket. The two plug-in parts 41 are respectively located at the left and right sides of the bottom of the connecting plate 4; the plug-in parts 41 slide and cooperate with the same side slide grooves 21. After the power adapter is used, the plug 12 of the adapter body 1 needs to be pulled out from the socket. First, the top plate 2 is rotated downward through the connecting plate 4 to rotate the top plate 2 from a vertical state to a longitudinal horizontal state. The specific rotation angle is 90 degrees. In this process, the lower end of the top plate 2 abuts against the socket to generate a reaction force, and then the adapter body 1 is pushed to move backward and pulled out from the socket. The top plate 2 cooperates with the connecting plate 4 to form a lever structure. The reaction force generated by the top plate 2 squeezing the socket drives the plug 12 of the adapter body 1 to be pulled out from the socket, preventing the plug 12 from loosening from the wall due to long-term plugging and unplugging of the socket, and also making the plug 12 more labor-saving to pull out.

[0040] When using the power adapter, first insert the plug 12 into the corresponding socket, the connecting plate 4 and the top plate 2 are both in a vertical state, at this time, one side of the connecting plate 4 and the contact surface 11 of the adapter body 1 are in contact with the socket, the connecting plane 43 is located on the upper side of the plug 12, and is in a semi-enclosed shape. After being fitted with the socket, the plug 12 is partially protected to prevent liquid from penetrating into the plug 12 from the gap between the connecting plane 43 and the socket, avoiding a short circuit between the plug 12 and the socket, and improving the waterproof performance of the power adapter. And after the side of the connecting plate 4 abuts against the socket, the elastic member 3 is still in a deformed state, providing thrust for the connecting plate 4, so that the connecting plate 4 can always fit tightly with the socket and is not easily affected by external forces. Since the top plate 2 is rotatably connected to the adapter body 1, the top plate 2 cooperates with the connecting plate 4 to form a labor-saving lever structure, and the connecting plate 4 of the power adapter can pull the connecting plate 4 to move upward through the cooperation of the plug-in portion 41 and the slide groove 21, thereby extending the distance between the force point and the fulcrum to achieve a more labor-saving purpose. If a jam occurs between the plug 12 and the socket, the connecting plate 4 can be pulled to extend the distance between the force point and the fulcrum to generate a greater force, so as to pull the plug 12 out of the socket, while also avoiding looseness between the socket and the wall caused by excessive pulling force.

[0041] In some embodiments of the present application, the side of the connecting plate 4 away from the adapter body 1 is gradually inclined upward in the direction of the connecting plane 43 to form a first inclined surface 42. Specifically, the first inclined surface 42 is located at the top surface of the connecting plate 4 and is gradually inclined downward from the front to the back. When liquid drips onto the connecting plate 4, the liquid can flow and fall to the rear along the first inclined surface 42, preventing the liquid from gathering in the direction of the plug 12, thereby further improving the safety performance of the adapter body 1.

[0042] In some embodiments of the present application, a partition portion 44 is provided on the inner side of the connection plate 4. After the plug-in portion 41 of the connection plate 4 is fully inserted into the slide groove 21, the partition portion 44 fits with the top of the adapter body 1 to block the gap between the inner side of the connection plate 4 and the adapter body 1. Specifically, by providing the partition portion 44 on the inner side of the connection plate 4, during the use of the power adapter, the connection plate 4 and the top plate 2 are both in a vertical state, and the plug-in portion 41 needs to be fully inserted into the slide groove 21. The partition portion 44 cooperates with the top of the adapter body 1 to block the gap between the inner side of the connection plate 4 and the adapter body 1, thereby preventing liquid from penetrating toward the plug 12 through the gap between the connection plate 4 and the adapter body 1.

[0043] In some embodiments of the present application, a stopper 7 is provided on one side of the adapter body 1, and the top plate 2 on the same side can be rotated to abut against the stopper 7, and the stopper 7 is used to limit the rotatable range of the top plate 2. Specifically, the stopper 7 is provided so that when the top plate 2 is rotated downward from a vertical state to a longitudinal horizontal state through the connecting plate 4, one side of the top plate 2 will abut against the stopper 7 and cannot continue to rotate downward, thereby limiting the rotatable range of the top plate 2, preventing the top plate 2 from directly rotating and colliding with the rear side of the adapter body 1 due to excessive force when rotating the top plate 2 downward, and ensuring the safety of pulling the plug 12 out of the socket by rotating the connecting plate 4 and the top plate 2.

[0044] In other embodiments, in order to limit the stability of the rotation range of the top plate 2, stoppers 7 are provided on both the left and right sides of the adapter body 1, and the stoppers 7 on both sides cooperate with the top plates 2 on both sides respectively.

[0045] In some embodiments of the present application, the plug-in portion 41 is provided with a mounting groove 411 on one side, a positioning block 5 is slidably provided in the mounting groove 411, a reset spring 6 is provided between the positioning block 5 and the bottom of the mounting groove 411, and a plurality of positioning grooves 22 are provided on one side wall of the slide groove 21 of the top plate 2, and the positioning block 5 cooperates with the positioning groove 22. Specifically, there are three positioning grooves 22 in the slide groove 21, and the three positioning grooves 22 are distributed along the depth direction of the slide groove 21 and are evenly spaced. When the connecting plate 4 needs to be pulled upward to extend the distance between the force point and the fulcrum, the positioning block 5 can be inserted into the corresponding positioning groove 22 to cooperate, extend the force point and the fulcrum to a suitable distance, and achieve the positioning effect; prevent the connecting plate 4 from sliding easily during the rotation of the top plate 2, and affect the removal of the plug 12.

[0046] In some embodiments of the present application, the edges on both sides of the end of the positioning block 5 are provided with bevels, both forming a second bevel 51, and the positioning groove 22 matches the shape of the end of the positioning block 5. Specifically, the upper and lower edges of the end of the positioning block 5 are set at bevels, and when the connecting plate 4 slides up and down, the positioning block 5 cooperates with the positioning groove 22 through the second bevel 51, squeezing the positioning block 5 back into the installation groove 411, and the reset spring 6 is squeezed and deformed until the positioning block 5 is aligned with the next positioning groove 22 as the connecting plate 4 moves, and the positioning block 5 is no longer squeezed, and the reset spring 6 is reset by the rebound force, thereby driving the positioning block 5 to move and reset and insert into the positioning groove 22 for positioning.

[0047] In some embodiments of the present application, rollers are rotatably provided at the ends of the top plate 2 away from the slide groove 21, and the top plate 2 can be rotated to contact and cooperate with the socket through the rollers. Specifically, by providing rollers at the lower end of the top plate 2, when the top plate 2 is rotated to cooperate with the socket to pull out the plug 12, the top plate 2 is abutted against the socket through the rollers. Since the rollers are rotatable, the friction between the top plate 2 and the socket is reduced, and the wear caused by the top plate 2 squeezing the socket when the plug 12 is pulled out is reduced.

[0048] In some embodiments of the present application, the top plate 2 is rotatably provided with a rotating shaft 13, the rotating shaft 13 passes through the top plate 2 and is connected to the adapter body 1, the elastic member 3 is sleeved on the rotating shaft 13, and a shielding portion 14 is provided at the end of the rotating shaft 13, and the shielding portion 14 is a cylindrical structure, which covers the elastic member 3. Specifically, the rotating shaft 13 is fixedly installed on the adapter body 1, and the top plate 2 is rotatably connected to the rotating shaft 13, so as to achieve the purpose of being rotatable on the adapter body 1; and a shielding portion 14 with a cylindrical structure is provided at the outer end of the rotating shaft 13 to cover the elastic member 3, thereby improving the overall aesthetics of the power adapter, and also preventing the elastic member 3 from causing damage to the user's skin when deformed, thereby improving safety.

[0049] In some embodiments of the present application, the elastic member 3 is a torsion spring. Specifically, the elastic member 3 can also be configured as a spiral spring.
