[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 4 A travel converter includes a power adapter 1 and a plug 2, wherein the power adapter 1 includes a first shell 11 and a first pin, the first shell 11 is provided with a plug-in slot 111, the first pin is installed in the plug-in slot 111, the plug 2 includes a second shell 21 and a second pin installed on the top of the second shell 21, the bottom of the second shell 21 is provided with a plug-in portion 211, the plug-in portion 211 is used to plug with the plug-in slot 111, the plug-in portion 211 is provided with a socket 213 at one end close to the first pin, the socket 213 A conductive terminal connected to the second pin is provided inside, the plug-in portion 211 is also provided with an elastic trigger portion 212, a locking protrusion 2122 is provided at the bottom of the elastic trigger portion 212, and the plug-in slot 111 is provided with a locking slot 112; when the plug-in portion 211 is plugged into the plug-in slot 111, the first pin is plugged into the socket 213 and connected to the conductive terminal, and the locking protrusion 2122 is snapped into the locking slot 112; when the elastic trigger portion 212 is pressed, the locking protrusion 2122 is disengaged from the locking slot 112.

[0024] From the above description, it can be seen that the beneficial effects of the utility model are: by providing an elastic trigger portion 212 on the plug-in portion 211 of the second shell 21, and providing a locking protrusion 2122 at the bottom of the elastic trigger portion 212, the locking protrusion 2122 cooperates with the locking groove 112 in the plug-in slide groove 111, thereby reducing the risk of the plug-in portion 211 being loosened in the reverse direction along its plug-in direction; and by pressing the elastic trigger portion 212, the locking protrusion 2122 can be disengaged from the locking groove 112 to achieve unlocking, thereby improving the convenience of use.

[0025] Furthermore, the first plug pin can be rotatably mounted on the plug-in slide slot 111 .

[0026] From the above description, it can be known that the first pin is rotatably mounted to the plug-in slot 111 so that the first pin can be unfolded for use. When the first pin is stored in the plug-in slot 111, it can cooperate with the socket 213 of the plug-in portion 211.

[0027] Furthermore, the elastic trigger portion 212 includes an elastic arm 2121 and a trigger button 2123, the elastic arm 2121 extends along the plug-in direction of the plug-in portion 211, and the extension direction of the trigger button 2123 is perpendicular to the extension direction of the elastic arm 2121; one end of the elastic arm 2121 is connected to the plug-in portion 211, the trigger button 2123 is connected to one end of the elastic arm 2121 away from the plug-in portion 211, and the locking protrusion 2122 is arranged at the bottom of the elastic arm 2121.

[0028] It can be seen from the above description that when the trigger button 2123 is pressed, the elastic arm 2121 is deformed, so that the locking protrusion 2122 is disengaged from the locking groove 112 .

[0029] Furthermore, the trigger button 2123 is also provided with a reinforcing rib connected to the elastic arm 2121 .

[0030] It can be seen from the above description that the reinforcing ribs can strengthen the structural strength of the elastic triggering portion 212 .

[0031] Furthermore, the number of the reinforcing ribs is multiple.

[0032] It can be seen from the above description that providing a plurality of reinforcing ribs can further enhance the structural strength of the elastic triggering portion 212 .

[0033] Furthermore, it also includes a sliding block, and a sliding groove is provided on the side of the trigger button 2123 away from the plug-in portion 211, and the extension direction of the sliding groove is the same as the extension direction of the trigger button 2123. The sliding block can be slidably installed in the sliding groove, and the sliding block is used to contact the side wall of the second shell 21; when the sliding block contacts the side wall of the second shell 21, the trigger button 2123 is locked; when the sliding block is disengaged from the side wall of the second shell 21, the trigger button 2123 is unlocked.

[0034] From the above description, it can be seen that a slidable sliding block is set on the trigger button 2123. By sliding the sliding block to a position where it conflicts with the side wall of the second shell 21, the trigger button 2123 can be locked, so that the trigger button 2123 cannot be pressed, thereby preventing the plug 2 and the power adapter 1 from loosening due to accidental touch; correspondingly, when the sliding block is slid to a position where it is separated from the side wall of the second shell 21, the trigger button 2123 can be unlocked, and the trigger button 2123 can be pressed at this time.

[0035] Furthermore, the plug-in portion 211 is also provided with a first anti-slip protrusion 214 extending along the plug-in direction of the plug-in portion 211, and the side wall of the plug-in groove 111 is also provided with a second anti-slip protrusion 113. When the plug-in portion 211 is plugged into the plug-in groove 111, the top of the first anti-slip protrusion 214 conflicts with the bottom of the second anti-slip protrusion 113.

[0036] As can be seen from the above description, the first anti-loosening protrusion cooperates with the second anti-loosening protrusion to prevent the plug 2 from loosening in a direction perpendicular to its plugging direction, further improving the reliability of the travel adapter.

[0037] Furthermore, the cross-sectional shape of the locking protrusion 2122 is trapezoidal, triangular, rectangular or semicircular.

[0038] It can be seen from the above description that the cross-sectional shape of the locking protrusion 2122 can be set according to actual application requirements.

[0039] Furthermore, the second plug pin is a European standard plug pin, an American standard plug pin, a British standard plug pin, an Australian standard plug pin or a Swiss standard plug pin.

[0042] Preferably, the first plug can be rotatably mounted on the plug-in slide slot 111. The first plug can be rotatably mounted on the plug-in slide slot 111, and the first plug can be unfolded for use. When the first plug is stored in the plug-in slide slot 111, it can be matched with the socket 213 of the plug-in portion 211. Specifically in this embodiment, the first plug is a Chinese standard plug; the specification of the first plug can be selected according to actual application requirements; the second plug is a European standard plug (such as Figure 1 As shown), US standard pins, UK standard pins (as shown Figure 4 As shown), Australian standard plug (as shown Figure 3 The type of the second plug can be selected according to actual application requirements.

[0043] Please combine Figure 1 and Figure 2The elastic triggering portion 212 includes an elastic arm 2121 and a trigger button 2123. The elastic arm 2121 extends along the plugging direction of the plug-in portion 211, and the extending direction of the trigger button 2123 is perpendicular to the extending direction of the elastic arm 2121. One end of the elastic arm 2121 is connected to the plug-in portion 211, and the trigger button 2123 is connected to one end of the elastic arm 2121 away from the plug-in portion 211. The locking protrusion 2122 is provided at the bottom of the elastic arm 2121. When the trigger button 2123 is pressed, the elastic arm 2121 is deformed, so that the locking protrusion 2122 is disengaged from the locking groove 112; specifically, the trigger button 2123 is also provided with a reinforcing rib (not shown) connected to the elastic arm 2121, and the reinforcing rib can strengthen the structural strength of the elastic trigger part 212; optionally, the number of the reinforcing ribs is multiple, and providing multiple reinforcing ribs can further enhance the structural strength of the elastic trigger part 212.
