[0039] The present application is further described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0040] like Figures 1 to 11 As shown, the coupler includes a lower coupler 2 of a retractable baffle plate, and also includes an upper coupler 1 that can be plugged and matched with the lower coupler 2 of the retractable baffle plate.

[0041] Specifically, the upper coupler 1 includes an upper coupler body 11, a plug pin 12 disposed in the upper coupler body 11, and a power connection line 13 integrally formed on the upper coupler body 11 and connected to the plug pin 12 for external power supply. The upper coupler body 11 is also provided with a connection hole 100 for connection. The advantage is that it is convenient for practical use.

[0042] Furthermore, the lower coupler 2 of the retractable baffle plate comprises a lower coupler body 21, a through hole 211 extending downward is formed on the upper side of the lower coupler body 21, and a receiving slot 212 is formed on the lower side of the through hole 211;

[0043] The lower coupler of the retractable baffle plate also includes a baffle plate 22 and an elastic telescopic member 23; the baffle plate 22 is arranged in the accommodating slot 212, and is provided with a connecting hole 221 that can be matched with the through hole 211; the elastic telescopic member 23 is arranged between the baffle plate 22 and the inside of the accommodating slot 212, and is used to telescopically move the baffle plate 22 to open and close the through hole 211.

[0044] In the present application, the elastic telescopic member 23 cooperates with the baffle plate 22 to telescope and open and close the through hole 211. When the baffle plate 22 is retracted into the accommodating slot 212, the connecting hole 221 on the baffle plate 22 is connected with the through hole 211 on the lower coupler body 21, that is, the through hole 211 is opened; when the baffle plate 22 extends out of the accommodating slot 212, the baffle plate 22 can close the through hole 211, which can not only facilitate the insertion of the pin 12 on the upper coupler 1 into the lower coupler 2, but also achieve a fully sealed dustproof and waterproof effect, thereby maximizing the safety and practicality of use.

[0045] Furthermore, a accommodating notch 222 for accommodating the elastic telescopic member 23 is provided on one side of the middle of the baffle plate 22, and an elastic telescopic member connecting portion 223 protruding along the opening direction thereof for connecting the elastic telescopic member 23 is provided on one side inside the accommodating notch 222. The purpose is to achieve the connection of the elastic telescopic member 23.

[0046] Furthermore, the elastic telescopic member 23 is preferably an elastic compression spring, which is intended to meet actual use requirements.

[0047] Furthermore, an upper convex portion 224 protruding upward is provided on the other side of the middle portion of the baffle plate 22, and an inclined slope 2241 inclined toward the opening direction of the accommodating slot 222 is provided on one side of the upper convex portion 224;

[0048] The upper side of the lower coupler body 21 is provided with a limiting notch 213 for adapting and limiting the upper protrusion 224 to prevent the anti-blocking plate 22 from continuing to move. The advantage is that when the upper coupler 1 moves downward and is inserted into the lower coupler 2, the anti-blocking plate 22 can be pushed into the accommodating notch 212 by squeezing the inclined slope 2241 on the upper protrusion 224, and vice versa, the anti-blocking plate 22 can be reset and pushed out by the elastic telescopic member 23, thereby realizing the automatic telescopic action of the anti-blocking plate 22.

[0049] Furthermore, a downwardly recessed position 2121 is provided at the lower middle side of the receiving slot 212;

[0050] The lower side of the middle part of the baffle plate 22 is provided with a lower convex portion 225 adapted to slide and connect with the lower concave position 2121. The advantage is that the sliding guide connection function is realized.

[0051] Furthermore, the number of the communicating holes 221 is multiple and they are arranged in two rows on both sides of the accommodating slot 222 to meet actual use requirements.

[0052] Furthermore, the baffle plate 22 is provided with a connection hole 226 located outside the two rows of the connecting holes 221, and a downward extending limit portion 227 extending downwardly and tilted to limit the baffle plate 22 from moving out of the receiving slot 212 is provided in the connection hole 226. The advantage is that the baffle plate 22 can be prevented from being separated from the receiving slot 212.

[0053] Furthermore, the inclination direction of the downwardly extending limiting portion 227 is the same as the inclination direction of the inclined slope 2241 , which has the advantage of avoiding hindering the inward contraction movement of the baffle plate 22 .

[0054] Furthermore, the through hole 211 and the connecting hole 221 are both circular holes, and the shape of the plug pin 12 is cylindrical, which meets the actual use requirements.

[0055] Furthermore, the through hole 211 and the connecting hole 221 may also be rectangular holes, and the shape of the plug pin 12 is a rectangular column, the purpose of which is to provide one more implementation method to meet more practical use requirements.

[0056] Furthermore, the lower coupler of the retractable baffle plate further comprises a spring block 24 and a wiring spring 25; the spring block 24 is inserted into the lower coupler body 21; the wiring spring 25 is clamped on the spring block 24 for connecting an external power supply line. The advantage is that it meets the actual use requirements.

[0057] In summary, the implementation methods of the present application have been described in detail, but the present application is not limited to the above implementation methods. Even if various changes are made to the present application, they still fall within the protection scope of the present application.
