The use of the adapter is very flexible and suitable for different scenarios and needs.

[0003] At present, the structure of traditional adapters is relatively simple. Most of them are fixed by matching the sizes of two connection ports and lack corresponding protective structures. Most of them are directly exposed to the outside world when in use and are easily affected by external shaking, which can easily cause poor contact. In addition, if the humidity of the environment in which they are used is high, it is easy for humid gas to enter the connection port through the connection port of the adapter, causing the connection port to be damaged faster, and the connection port of the adapter is prone to aging and damage. Internal circuit leakage and short circuit are prone to occur over a long period of time, thereby reducing safety during use.

[0004] Therefore, it is necessary to modify the traditional adapter to effectively prevent the adapter from being directly exposed to the outside world during use, which may easily cause poor contact due to external shaking, and the adapter's connection port may be easily aged and damaged when used in a humid environment, which may easily cause internal circuit leakage and short circuit problems over a long period of time.

[0022] refer to Figure 1 and Figure 2The two sides of the protection box 1 are symmetrically threadedly connected with torsion posts 13 extending into the protection box, and the ends of the torsion posts 13 are rotatably connected with a clamp 14 that fits the adapter body through a bearing.

[0023] As a technical optimization solution of the utility model, the adapter body 3 can be positioned by setting the torsion column 13 and the clamp 14 to avoid shaking of some smaller adapter bodies 3 in the protective box 1, thereby improving the practicality of the device.

[0024] refer to Figure 2 The top of the platform outside the adapter body is provided with a heat absorbing liner 15.

[0025] As a technical optimization solution of the present invention, by providing the heat-absorbing inner tank 15, it is possible to absorb heat from overload of the adapter body 3 when using high-power electrical appliances, thereby reducing the risk.

[0026] refer to Figure 1 A heat dissipation mesh 17 is fixedly connected inside the heat dissipation groove 16 .

[0027] As a technical optimization solution of the present invention, by providing the heat dissipation grooves 16 and the heat dissipation mesh strips 17, the heat absorbed by the heat-absorbing inner tank 15 can be discharged in time, thereby further improving the safety of use.

[0028] refer to Figure 2 A plurality of reinforcing ribs 18 are symmetrically fixedly connected to both sides of the top of the platform, and the plurality of reinforcing ribs 18 are evenly arranged.

[0029] As a technical optimization solution of the present invention, by providing a plurality of reinforcing ribs 18, the strength of the protective box 1 itself can be improved to make it more durable.

[0031] As a technical optimization solution of the utility model, through the arrangement of the rubber ring 19 and the electrical fire extinguishing agent 20, if the adapter body 3 is short-circuited or catches fire due to improper use, the flame can burn through the rubber ring 19, causing the electrical fire extinguishing agent 20 to leak out, thereby achieving the effect of timely extinguishing the fire.

[0032] The working principle and use process of the utility model are as follows: when the staff uses the protective device of the adapter, first, the connecting wire 12 on one side is passed through the connecting port 10 on the protective box 1 and clamped with the connecting port of the adapter body 3, and then the connecting wire 12 is pulled to drive the adapter body 3 to be recovered into the placement port 2. At this time, the surface of the connecting wire 12 is sealed and slid inside the sealing ring 11, and then the torsion column 13 can be rotated to drive the clamp 14 to clamp and position the adapter body 3, and then the connecting wire 12 to be transferred is passed through the connecting port 10 on the box cover 4 to connect it with the other connecting port of the adapter body 3, and then the box cover 4 is slid to align it with the placement port 2, and the sealing clamp ring 6 is completely clamped into the sealing clamping groove 5, at this time the threaded groove 7 is aligned with the threaded hole 8, and then the four bolts 9 are sequentially tightened. It can be connected with the four threaded holes 8 and the threaded grooves 7. At this time, through the cooperation of the sealing groove 5, the sealing clamp ring 6, the connecting port 10 and the sealing ring 11, the gap between the protection box 1 and the box cover 4 and the gap where the connecting wire 12 is inserted into the connecting port 10 can be sealed, so as to achieve the effect of preventing humid air or water from entering the interior of the protection box 1, and then the connection of the adapter body 3 can be protected. During the use of the device, the heat generated by the adapter body 3 can be absorbed by the heat absorbing inner liner 15, and then the heat absorbed by the heat absorbing inner liner 15 is discharged in time through the heat dissipation groove 16 and the heat dissipation mesh strip 17. If the adapter body 3 is short-circuited or catches fire due to improper use, the flame will burn through the rubber ring 19, causing the electrical fire extinguishing agent 20 to leak out, thereby achieving the effect of timely extinguishing the fire.
