Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a foldable power adapter. Background Technology

[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. Its working principle is to convert AC input to DC output. For easy portability, most power adapters are now designed with a foldable plug.

[0003] For example, CN218732066U discloses a power adapter with a foldable plug, including a power adapter body. A charging indicator light is embedded in the top of the power adapter body. A folding groove is formed at the center of one end of the wider side of the power adapter body. Rotating holes are symmetrically formed at the top and bottom corners of the inner side of the folding groove. This utility model, through the design of a power adapter with a foldable plug, allows the position of the electrode plates when inserted into the socket to be adjusted by rotating the rotating base 180°. This makes the insertion of the electrode plates within a certain size range not limited by the width of the power adapter body 1, making the entire power adapter more convenient to use. This effectively solves the problem that the plug of a traditional power adapter can only be inserted into the socket in one direction, and the insertion is limited by the width of the power adapter when the gap between the socket and the nearby plug is small.

[0004] However, while this foldable power adapter allows for good folding of the plug, the protection at the folding slot is not very effective after the plug is folded and stored. Furthermore, the protective cover is not very effective at being stored on the adapter surface after being removed, and it is not very effective at preventing loss. This affects the durability of the protective cover's protection at the folded plug area.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a foldable power adapter. Utility Model Content

[0006] The purpose of this utility model is to provide a foldable power adapter to solve the problems mentioned in the background art, such as the poor protection effect of the folding slot after the plug is folded and stored, and the poor storage effect of the protective cover on the adapter surface after the protective cover is removed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foldable power adapter, comprising an adapter body, a data cable inserted into the top of the adapter body, a plug rotatably connected to the bottom of the adapter body, a storage groove formed at the connection between the bottom of the adapter body and the plug, a protective sleeve inserted into the inner wall of the storage groove, a plug block fixedly connected to the side wall of the adapter body, a connecting rod slidably connected to the outer wall of the protective sleeve, a positioning rod slidably connected to the outer wall of the adapter body, a sliding groove formed at the connection between the outer wall of the adapter body and the positioning rod, a spring fixedly connected to the outer wall of the positioning rod and the outer wall of the adapter body, and a slot formed at the connection between the outer wall of the connecting rod and the plug block.

[0008] Furthermore, the outer contour of the protective sleeve is adapted to match the inner contour of the storage groove, and the overall material of the protective sleeve is transparent plastic.

[0009] Furthermore, the plug is provided in two sets, and the positions of the two sets of plugs are symmetrical about the central axis of the adapter body, and the outer wall contour of the plug is "L" shaped.

[0010] Furthermore, the positioning rod forms a sliding structure with the adapter body through a groove and a spring, and the outer wall contour of the positioning rod is "L" shaped.

[0011] Furthermore, the inner wall contour of the slot is adapted to the outer wall contour of the insert and the positioning rod, and the slot is set on the movement trajectory of the positioning rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the design of a protective sleeve and a positioning rod, enhances the protection of the plug on the power adapter surface during daily use. It also effectively secures the protective sleeve during storage. When the plug needs to be used, the protective sleeve can be pulled out of the storage slot, and the plug can be rotated to put it into use. The connecting rod is then inserted into the outer wall of the plug block via the slot connection. Loosening the positioning rod, under the reaction force of the stretched spring, causes the positioning rod to slide along the inner wall of the groove, inserting it into the slot. This effectively secures the protective sleeve to the side wall of the adapter, preventing loss when the protective sleeve is not in use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0021] Example: Figures 1-5 As shown, a foldable power adapter includes an adapter body 1, a data cable 2 inserted into the top of the adapter body 1, a plug 3 rotatably connected to the bottom of the adapter body 1, a storage groove 4 formed at the connection between the bottom of the adapter body 1 and the plug 3, a protective sleeve 5 inserted into the inner wall of the storage groove 4, a plug block 6 fixedly connected to the side wall of the adapter body 1, a connecting rod 7 slidably connected to the outer wall of the protective sleeve 5, a positioning rod 8 slidably connected to the outer wall of the adapter body 1 and the outer wall of the protective sleeve 5, a sliding groove 9 formed at the connection between the outer wall of the adapter body 1 and the positioning rod 8, a spring 10 fixedly connected to the outer wall of the positioning rod 8 and the outer wall of the adapter body 1, and a slot 11 formed at the connection between the outer wall of the connecting rod 7 and the plug block 6.

[0022] Furthermore, the outer contour of the protective sleeve 5 is adapted to the inner contour of the storage groove 4. The overall material of the protective sleeve 5 is transparent plastic, which helps to achieve effective protection for the plug 3 when it is stored by adapting the outer contour of the protective sleeve 5 to the inner contour of the storage groove 4.

[0023] Furthermore, there are two sets of plugs 6, and the positions of the two sets of plugs 6 are symmetrical about the central axis of the adapter body 1. The outer wall contour of the plugs 6 is "L" shaped, which is beneficial to effectively store the protective cover 5 when not in use by setting two sets of plugs 6 with their positions symmetrical about the central axis of the adapter body 1.

[0024] Furthermore, the positioning rod 8 forms a sliding structure with the adapter body 1 through the slide groove 9 and the spring 10. The outer wall contour of the positioning rod 8 is "L" shaped, which facilitates the positioning rod 8 to move up and down conveniently along the inner wall of the slide groove 9 on the side wall of the adapter body 1 through the connection of the spring 10, so as to effectively lock and fix the protective sleeve 5 when it is stored.

[0025] Furthermore, the inner wall contour of the slot 11 is adapted to the outer wall contour of the insert 6 and the positioning rod 8, and the slot 11 is set on the movement trajectory of the positioning rod 8. This arrangement of the inner wall contour of the slot 11 to the outer wall contour of the insert 6 and the positioning rod 8 helps to effectively prevent the protective sleeve 5 from being lost when it is stored.

[0026] Working principle: When using this foldable power adapter, in order to improve the protection of the plug 3 on the adapter surface and the effective locking and fixing of the protective cover 5 during daily use, the protective cover 5 can be pulled out from the storage slot 4 when the plug 3 needs to be used, and the plug 3 can be rotated to put the plug 3 into use. Then, the connecting rod 7 is inserted into the outer wall of the plug block 6 through the connection of the slot 11, and the positioning rod 8 is loosened. Under the reaction force of the stretched spring 10, the positioning rod 8 is driven to slide along the inner wall of the slide groove 9, so that the positioning rod 8 is inserted into the slot 11, which can effectively lock and store the protective cover 5 on the side wall of the adapter, and achieve the effect of storing the protective cover 5 to prevent loss when not in use.

[0027] This is how this foldable power adapter works.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
