Description

Technical Field

[0001] This utility model relates to the field of adapter technology, specifically to a plug-in adapter structure that prevents loosening. Background Technology

[0002] With the widespread use of electronic devices, adapters, as key components for power conversion and transmission, are widely used in mobile phones, laptops, home appliances, and other fields. Plug-in adapters typically consist of an adapter body and a plug. The plug connects to a power outlet via prongs, while the adapter body connects to the electronic device via a cable or interface to achieve voltage conversion and power supply functions.

[0003] However, the connection structure between the plug and the adapter body of existing plug-in adapters has obvious defects: the connection between the two mostly relies on simple plug-in and plug-out cooperation or a single snap-fit ​​design, lacking a stable limiting structure. This design makes the plug very easy to loosen due to external force during actual use. For example, when the adapter cable is accidentally pulled or tripped, the connection between the plug and the adapter body will be relatively displaced. This can lead to poor contact, power outage, and affect the normal use of the equipment; or even cause electrical sparks due to loose contact points, resulting in short circuits, equipment damage, or even fire hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a non-loosening plug-in adapter structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plug-in adapter structure for preventing loosening, comprising an adapter body, a plug, and a limiting structure;

[0006] The plug is inserted inside the adapter body, the width of the plug decreases sequentially from front to back, and the limiting structure is provided on the adapter body;

[0007] The limiting structure includes two limiting plates, which are symmetrically arranged on the bottom end of the adapter body facing the plug. Both limiting plates are hinged to the adapter body through a hinge shaft, and the two limiting plates are respectively attached to the left and right sides of the plug.

[0008] Both limiting plates are bent in opposite directions on the side facing the plug to form a bent portion, and one of the limiting plates is provided with a connecting component for connecting the other limiting plate.

[0009] Furthermore, the shapes of the two limiting plates on opposite sides are respectively adapted to the shapes of the left and right sides of the plug.

[0010] Furthermore, the two limiting plates are arranged in a figure-eight shape.

[0011] Furthermore, the connecting assembly rotates on a pivot on the upper surface of one of the limiting plates, and a connecting plate is fixedly sleeved on the outside of the pivot, with a connecting bolt passing through the end of the connecting plate away from the pivot.

[0012] Furthermore, corresponding to the connecting bolt, a threaded hole adapted to the connecting bolt is provided on the upper end face of another limiting plate.

[0013] Furthermore, the connecting plate is positioned above the plug.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The anti-loosening plug-in adapter structure has two limiting plates in the limiting structure that fit the plug perfectly with their inner shape. After fitting together, they can form a tight wrap from the left and right sides. The bent part further clamps the edge of the plug to limit its front and back displacement. Combined with the fixing of the connecting plate and connecting bolt in the connecting assembly, the limiting plates cannot rotate at will, thus forming an effective limiting protection.

[0016] 2. The anti-loosening plug-in adapter structure, with the rotating engagement of the connecting component's shaft and the connecting plate, makes the fixing and loosening of the two limiting plates simple, requiring only the tightening of the connecting bolts, and the disassembly process will not damage the components.

[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] Please see Figure 1-2The plug-in adapter structure for preventing loosening in this embodiment includes an adapter body 1, a plug 2 and a limiting structure 3. The three components work together to achieve a stable connection between the plug 2 and the adapter body 1, thus solving the problem of loosening caused by external force dragging.

[0022] In actual setup, the adapter body 1 is the core functional module of the adapter, with a slot inside that matches the plug 2 for circuit conduction and power conversion. The plug 2 is a component that is inserted into the mains socket. Its width decreases from front to back and has a wedge-shaped structure. It is inserted into the slot of the adapter body 1 to achieve initial electrical connection with the adapter body 1.

[0023] In detail, the limiting structure 3 is installed at the bottom of the adapter body 1, including two left and right symmetrical limiting plates 301. The two limiting plates 301 are symmetrically installed at the bottom of the adapter body 1 facing the plug 2 through a hinge axis, and can rotate freely around the hinge axis. The side of the limiting plate 301 facing the plug 2 is bent to form a bent part 3011, and the shape of the opposite side of the two limiting plates 301 is completely adapted to the shape of the left and right sides of the plug 2. Since the plug 2 is wedge-shaped, the inner side of the limiting plate 301 also has a corresponding tilt angle.

[0024] In actual use, after the plug 2 is inserted into the adapter body 1, the two limiting plates 301 are rotated so that the two limiting plates 301 are respectively attached to the left and right sides of the plug 2. Then, the two limiting plates 301 are connected by the connecting component, so that the two limiting plates 301 are tightly attached to the two sides of the plug 2, effectively limiting the plug 2 and preventing the plug 2 from being pulled out of the adapter body 1 when it is dragged by external force.

[0025] More specifically, the connecting assembly includes a rotating shaft 302, a connecting plate 303, and a connecting bolt 304: the rotating shaft 302 is fixed to the upper end face of one of the limiting plates 301, the connecting plate 303 is sleeved on the outside of the rotating shaft 302 and can rotate around it, a through hole is opened at the end of the connecting plate 303 away from the rotating shaft 302, and the connecting bolt 304 passes through the through hole. Correspondingly, a threaded hole matching the connecting bolt 304 is opened on the upper end face of the other limiting plate 301.

[0026] In actual use, when the two limiting plates 301 are attached to the plug 2, the connecting plate 303 can be rotated to cover the upper surface of the other limiting plate 301. The two limiting plates 301 are fixed by the cooperation of the connecting bolt 304 and the threaded hole. After the two limiting plates 301 are attached to the plug 2, the connecting plate 303 is rotated to straddle the upper surface of the two limiting plates 301. Tightening the connecting bolt 304 can firmly lock the two limiting plates 301. At this time, the limiting plate 301 cannot rotate around the hinge axis, and its inner side is tightly attached to the wedge-shaped side of the plug 2, clamping the plug 2 onto the adapter body 1.

[0027] The working principle of the above embodiments is as follows:

[0028] (1) After the plug 2 is fully inserted, rotate the two limiting plates 301 in the opposite direction so that their inner sides fit the left and right sides of the plug 2. Since the shape of the limiting plate 301 is adapted to the plug 2, the bent part 3011 will lock the edge of the plug 2 and restrict its forward and backward movement. Then, rotate the connecting plate 303 so that it rotates around the rotating shaft 302 until it covers the upper end face of the other limiting plate 301. Screw the connecting bolt 304 into the corresponding threaded hole. The two limiting plates 301 are firmly fixed by the pulling force of the connecting plate 303. At this time, the plug 2 is clamped by the limiting plate 301 and cannot move forward and backward.

[0029] (2) When the adapter cable is subjected to a dragging force, the pulling force is transmitted to the limiting structure 3 through the adapter body 1. The limiting plate 301 cannot be opened due to the fixing of the connecting bolt 304. Its inner side is tightly fitted with the wedge-shaped side of the plug 2. The friction force generated and the blocking force of the bending part 3011 together offset the dragging force, preventing the plug 2 from being loosened from the adapter body 1. When the plug 2 needs to be pulled out, loosen the connecting bolt 304, rotate the connecting plate 303 to make it separate from the other limiting plate 301, and rotate the two limiting plates 301 outward to make them separate from the plug 2. The plug 2 can then be easily pulled out. The operation is convenient and does not damage the components.
