[0015] The assembled charger 10 is provided with a charger body 11 and a replaceable plug 12, and an internal component 112 including a shell 1121, a transmission assembly 1122, a first column 1123 and a second column 1124 is provided in the main shell 111 of the charger body 11. The upper ends of the first column 1123 and the second column 1124 extend out of the shell 1121 and extend out of the main shell 111 through corresponding holes. The lower ends of the first column 1123 and the second column 1124 are connected by transmission assembly 1122, and cooperate with the first column 11 The first spring 101 and the second spring 102 are respectively sleeved outside the first column 1123 and the second column 1124, so that the first column 1123 and the second column 1124 can move with the movement of either side, so that the upper ends of the first column 1123 and the second column 1124 can simultaneously extend and insert into the corresponding jacks of the plug body 121 of the interchangeable plug 12, so as to lock the connection between the charger body 11 and the interchangeable plug 12, ensure the stable connection between the interchangeable plug 12 and the charger body 11, and prevent the charger body 11 and the interchangeable plug 12 from separating. The plug 121 has a protective effect, and the plugging and unplugging process will not cause wear to the first column 1123 and the second column 1124, which can effectively avoid unstable connection due to repeated plugging and unplugging. At the same time, the interchangeable plug 12 includes a plug body 121 and a button 122. The plug body 121 is provided with a groove 1213 for mounting the button 122 and the end of which is connected to the first jack 1211, so that the button 122 is placed in the groove 1213, the top of the button 122 extends out of the top of the groove 1213 and is located outside the plug body 121, and the end of the button 122 is located in the groove 121 3, when the top of button 122 is pressed, the end of button 122 is located at the end of slot 1213, causing it to apply pressure to the top of first column 1123 inserted into first jack 1211, causing first column 1123 to retract, thereby driving second column 1124 to retract, unlocking the connection between charger body 11 and interchangeable plug 12, allowing charger body 11 to be separated from interchangeable plug 12, facilitating replacement and maintenance of interchangeable plug 12. A third spring 103 is provided on the outer cover of button 122 to facilitate reset of button 122. Extension and retraction refer to the movement of the corresponding column extending or retracting relative to the corresponding through hole.

[0016] Specifically, in this embodiment, the inner diameter of the distal end of the groove 1213 is smaller than the inner diameter of the midsection of the groove 1213, thereby forming a rib within the groove 1213. One end of the third spring 103 is connected to the rib. The button 122 is rod-shaped, and the midsection of the button 122 may radially protrude outward to form a rib. The other end of the third spring 103 may be connected to the rib. The distal end of the groove 1213 defines an opening corresponding to the first receptacle 1211. A guide surface is formed on the distal end of the button 122 near the opening.

[0017] Specifically, in this embodiment, the transmission assembly 1122 includes a turntable 1125, a first slider 1126 and a rotating member 1127. The turntable 1125 is installed in the housing 1121 in a rotatable and left-right limited manner through the shaft 104. The turntable 1125 is connected to the lower end of the first column 1123 through the connecting shaft 105. The two ends of the first slider 1126 are respectively connected to the lower end of the second column 1124 and the turntable 1125. The first slider 1126 is provided with a slider limiting groove 1001. The interior of the housing 1121 is connected to a suspension. The empty end passes through the slider connecting shaft 106 of the slider limiting groove 1001, so that the first slider 1126 is installed in the shell 1121 in a manner that it can move left and right and be limited front and back. The rotating member 1127 is installed in the shell 1121 in a manner that it can rotate and be limited left and right through the connecting shaft 107. The turntable 1125 is transmission-connected to the rotating member 1127 so that the turntable 1125 can drive the rotating member 1127 to move. A push rod 1128 is formed by extending outward from one side of the rotating member 1127, and the push rod 1128 is connected to the second column 1124. Among them, the first slider 1126 is located between the turntable 1125 and the second column 1124. The turntable 1125 and the rotating member 1127 are set to convert the linear motion of the first column 1123 and the second column 1124 into rotational motion and transmit it. The cooperation between the first slider 1126 and the turntable 1125 can realize the conversion and transmission between the linear motion of the second column 1124 and the rotational motion of the turntable 1125. The first column 1123 is connected to the turntable 1125 through the connecting shaft 105 so that the first column 1123 moves with the converted rotation, and the rotational motion of the turntable 1125 is converted into the linear motion of the first column 1123, so that the transmission component 1122 can be used to realize the transmission between the first column 1123 and the second column 1124. By setting the slider limit groove 1001, the position of the first slider 1126 can be limited to prevent the first slider 1126 from being separated from the lower end of the second column 1124 and the turntable 1125, and the movement of the first slider 1126 is made more stable and reliable. The moving distance of the first slider 1126 is limited, thereby determining the moving distance of the first column 1123 and the second column 1124, thereby ensuring the reliability of the connection between the interchangeable plug 12 and the charger body 11, and the accuracy of the movement direction can be guaranteed by the slider limit groove 1001.

[0018] Specifically, in this embodiment, a locking position is provided on the second column 1124, and the suspended end of the push rod 1128 is connected to the locking position, so that when the rotating member 1127 rotates counterclockwise, the push rod 1128 moves with the rotating member 1127 and pushes the second column 1124 to extend, and when the rotating member 1127 rotates clockwise, the push rod 1128 moves with the rotating member 1127 and drives the second column 1124 to retract.

[0019] Specifically, in this embodiment, the second column 1124 is located above the first slider 1126, and the end of the first slider 1126 close to the second column 1124 is formed with a guide surface inclined from top to bottom and outward, and the lower end of the second column 1124 is formed with a guide surface corresponding to the guide surface.

[0020] Specifically, in this embodiment, a locking position is formed on one side of the rotating member 1127 close to the turntable 1125, and a locking edge is formed on the turntable 1125 corresponding to the locking position, and the locking edge is connected to the locking position, so that when the turntable 1125 rotates clockwise, the connection between the locking edge and the locking position pushes the rotating member 1127 to rotate counterclockwise; and when the turntable 1125 rotates counterclockwise, the connection between the locking edge and the locking position pushes the rotating member 1127 to rotate clockwise.

[0021] Specifically, the elastic force of the second spring 102 is greater than the elastic force of the first spring 101. Preferably, in the initial state, the second spring 102 may be in a compressed state. When the pressure of the second spring 102 is released, the lower end of the second column 1124 exerts a thrust on the first slider 1126, causing the first slider 1126 to push the turntable 1125 to rotate clockwise, driving the first column 1123 connected to the turntable 1125 to extend. The clockwise rotation of the turntable 1125 drives the rotating member 1127 to rotate counterclockwise, and the push rod 1128 moves with the rotation member 1127 to push the second column 1124 to extend. At this time, the first column 1123 and the second column 1124 both extend and are in a locked state, which is conducive to the locking of the connection between the charger body 11 and the interchangeable plug 12.

[0022] Specifically, in this embodiment, the interior of the shell 1121 is provided with a first limiting rod 107 and a second limiting rod 108 corresponding to the first through hole and the second through hole respectively, the first column 1123 is provided with a first limiting groove 1101 along the length direction of the first column 1123, and the suspended end of the first limiting rod 107 passes through the first limiting groove 1101, so that the first column 1123 is installed in the shell 1121 in a manner that it can move up and down and limit the front and back, and the second column 1124 is provided with a second limiting groove 1102 along the length direction of the second column 1124, and the suspended end of the second limiting rod 108 passes through the second limiting groove 1102, so that the second column 1124 is installed in the shell 1121 in a manner that it can move up and down and limit the front and back. By setting the first limiting groove 1101 and the second limiting groove 1102, the movement distance and position of the first column 1123 and the second column 1124 can be limited, thereby improving the safety and reliability of the connection.

[0023] Specifically, in this embodiment, the lower end of the first column 1123 extends outward to form a connecting piece 1129 , and one end of the connecting shaft 105 passes through the connecting piece 1129 to be connected to the rotating disk 1125 .

[0024] Specifically, in this embodiment, the radial dimension of the lower end of the first column 1123 is greater than the radial dimension of the upper end of the first column 1123, and the radial dimension of the lower end of the second column 1124 is greater than the radial dimension of the upper end of the second column 1124.

[0025] Specifically, in this embodiment, a slide groove 124 is provided on one side of the plug body 121 on which the first socket 1211 and the second socket 1212 are provided. The first socket 1211 and the second socket 1212 are located on the slide groove 124. The main body shell 111 is provided with a protruding boss 114 corresponding to the slide groove 124. The boss 114 can move along the slide groove 124 so that the boss 114 is installed in the slide groove 124, and the upper end of the first column 1123 and the upper end of the second column 1124 are inserted into the corresponding sockets, so that the charger body 11 and the interchangeable plug 12 are firmly connected.

[0026] Based on the above design, during operation, when the charger body moves along the slide groove through the boss to connect with the interchangeable plug, the plug body of the interchangeable plug applies thrust to the second column, the second spring is compressed, the second spring releases pressure, and the lower end of the second column has a thrust on the first slider, so that the first slider pushes the turntable to rotate clockwise, driving the first column connected to the turntable to extend so that the upper end of the first column is inserted into the first socket of the interchangeable plug, and the clockwise rotation of the turntable drives the rotating part to rotate counterclockwise, and the push rod pushes the second column to extend with the movement of the rotating part, so that the upper end of the second column is inserted into the second socket of the interchangeable plug, thereby realizing the connection and locking of the charger body and the interchangeable plug. When unlocking, the button is pressed, the third spring is compressed, and the end of the button enters the end of the slot to apply pressure to the upper end of the first column inserted into the first jack, and the first column retracts, the first spring is stretched, and the first column drives the turntable to rotate counterclockwise, so that the rotating part rotates clockwise and drives the second column to retract, the second spring is stretched, and the first column and the second column are both in a retracted state. At this time, the interchangeable plug and the charger body can be separated. When the boss of the charger body moves along the slide groove and disengages from the interchangeable plug, the unlocking is completed, and the first slider pushes the second column to extend. The first spring and the second spring respectively drive the first column and the second column to reset according to the spring characteristics. The first column and the second column extend and return to the initial state.

[0027] In summary, the assembled charger of the present invention is provided with a charger main body and a replaceable plug, and an internal component including a shell, a transmission assembly, a first column and a second column is provided in the main shell of the charger main body.

The lower ends of the first column and the second column are connected by transmission assembly, and cooperate with the first spring and the second spring respectively sleeved outside the first column and the second column, so that the first column and the second column can move with the movement of either side, so that the upper ends of the first column and the second column can simultaneously extend and be inserted into the corresponding jacks of the plug main body of the replaceable plug to lock the connection between the charger main body and the replaceable plug, ensure the stable connection between the replaceable plug and the charger main body, prevent the charger main body and the replaceable plug from being separated, and play a role. The plug and unplug process will not cause wear to the first column and the second column, which can effectively avoid unstable connection caused by repeated plugging and unplugging. At the same time, the interchangeable plug includes a plug body and a button. The plug body is provided with a slot for mounting the button and the end of which is connected to the first jack, so that the button is placed in the slot, the top of the button extends out of the top of the slot and is located outside the plug body, and the end of the button is located in the slot. When the top of the button is pressed, the end of the button can be located at the end of the slot, so that it applies pressure to the top of the first column inserted into the first jack, causing the first column to retract, thereby driving the second column to retract, unlocking the connection between the charger body and the interchangeable plug, so that the charger body can be separated from the interchangeable plug, which is convenient for replacement and maintenance of the interchangeable plug, and the button sleeve is provided with a third spring to reset the button.
