TECHNICAL FIELD

[0001] The utility model relates to a kind of travel socket with prevent same function. BACKGROUND

[0002] Common travel socket is generally provided with multiple plug assemblies corresponding to different countries or regions electrical specifications, these plug assemblies are stored in socket housing, and the plug assembly of corresponding specification is pushed out of socket housing when using. This structure is generally triggered by multiple toggle buttons to make plug assembly move, when one plug assembly is pushed out, due to internal structure interference with each other, so that two or more plug assemblies are pushed out simultaneously, which not only affects the dial plug of travel socket, but also easily produces spark breakdown in socket, socket temperature rises and can cause fire, with safety hazard. For this, travel socket needs to be provided with anti-same-out structure to avoid the situation that multiple plug assemblies are pushed out simultaneously.

[0003] For example, a power converter disclosed in Chinese patent 201711248282.7, the anti-same-out structure adopted by the power converter includes multiple pins, movable bolts and locking springs provided in the housing, the locking springs are arranged between the pins and the bottom shell; the slide sleeve has a curved arm extending downward at one end, when the button is located at the bottom end of the slide groove, the curved arm presses on the pin and compresses the locking spring; when the button is slid upward to the top end of the slide groove, the curved arm corresponding to the button is separated from the corresponding pin to make the pin pop out, and the movable bolts are moved to the two sides away from the pin through the pin to block other curved arms. It can be seen that although the structure solves the problem of anti-same-out, the internal structure is complex, there are many small parts, which leads to great difficulty in production and assembly, affecting production efficiency and cost.

[0025] The utility model discloses a travel socket with the function of preventing the same outlet, including shell 1 and plug assembly 2, plug assembly 2 includes a turn-up plug 21 and two push-out plugs 22 that are located at the both ends of turn-up plug 21 respectively, is equipped with a locking crossbar 3 in shell 1, locking crossbar 3 is configured as being forced to shift to stop the turn-up or push-out operation of the remaining plug when any plug is turned up or pushed out of the shell, and it is automatically reset after the plug is brought into shell 1, and locking crossbar 3 is provided with elastic mechanism 4 between shell 1 to provide reset torque for it. Figure 3 ,5 , 7, 9 and 11, the two ends of the locking crossbar 3 respectively point to the push-out plug 22 and abut against the base of the push-out plug 22 when the push-out plug 22 is slidably pushed out of the shell 1, thereby being forced to shift; in order to make the push-out plug 22 more smoothly pushed out, the end of the locking crossbar 3 pointing to the push-out plug 22 is provided with a bevel or a rounded surface 31, when the push-out plug 22 is pushed out, the base of the push-out plug 22 naturally presses the bevel or the rounded surface 31 of the end of the locking crossbar 3, thereby generating a moment to force the locking crossbar 3 to shift.

[0026] The locking crossbar 3 is provided with a locking groove 32, and a locking block 5 capable of being triggered into the locking groove 32 when the flip plug 21 is flipped is arranged in the shell 1, the locking block 5 is arranged at the lower part of a movable column 6 and opposite to the locking crossbar 3, the locking groove 32 is located at the side of the locking crossbar 3 opposite to the movable column 6, the movable column 6 is perpendicular to the locking crossbar 3 and the upper end of the movable column 6 is connected by an elastic member to provide a moment to push the movable column 6 downward, when the flip plug 21 is flipped, the base 211 of the flip plug 21 pushes the movable column 6 to the direction of the elastic member to contract, thereby enabling the locking block 5 to enter into the locking groove 32 of the locking crossbar 3, and the locking block 5 leaves the locking groove 32 after the flip plug 21 is received into the shell 1.

[0027] Referring to the drawings Figure 3 In the free state, the two ends of the locking crossbar 3 are respectively located below the base of the push-out plug 22 and the bevel or the rounded surface 31 is opposite to the base of the push-out plug 22, at the same time, the locking groove 32 of the locking crossbar 3 is opposite to the position of the locking block 5 to enable the locking block 5 to enter or leave the locking groove 32 when vertically shifting.

[0028] Referring to the drawings Figure 5 and 6 When any push-out plug 22 is slidably pushed out of the shell 1, the locking crossbar 3 is forced to shift, so that the other end of the locking crossbar 3 stops at the base of the other push-out plug 22 to limit the push-out plug 22 from being pushed out, and due to the shift of the locking crossbar 3, the position of the locking groove 32 deviates from the locking block 5, thereby limiting the shift of the locking block 5 and the flipping operation of the flip plug 21.

[0029] Referring to the drawings Figure 9 When the flip plug 21 is flipped, the locking block 5 enters into the locking groove 32, at this time, the lateral shift of the locking crossbar 3 is limited, thereby unable to be pressed by the push-out plug 22 to make the end of the locking crossbar 3 to shift, that is, the push-out operation of the two push-out plugs 22 is limited.

[0030] Regarding the elastic mechanism 4, the following structure is adopted in the embodiment:

[0031] Referring to the drawingsFigure 11 The middle part of the locking crossbar 3 is provided with a support body 33, and coaxial left and right elastic members 34 and 35 are arranged on both sides of the support body 33, which can be springs; the shell 1 is provided with support points 11 connected with the left and right elastic members 34 and 35.

[0032] Referring to the accompanying drawings Figure 3 In the free state, the locking groove 32 of the locking crossbar 3 is located above the locking block 5 under the torque balance of the left and right elastic members 34 and 35; referring to the accompanying drawings Figure 5 When the left end of the locking crossbar 3 is forced to move the rod body to the right, the left elastic member 34 is in a relaxation / or stretching state, and the right elastic member 35 is in a compression state, so that the locking crossbar 3 is provided with a left reset torque under the action of the right elastic member 35 or the left and right elastic members 34 and 35. Similarly, referring to the accompanying drawings Figure 7 When the right end of the locking crossbar 3 is forced to move the rod body to the left, the right elastic member 35 is in a relaxation / or stretching state, and the left elastic member 34 is in a compression state, so that the locking crossbar 3 is provided with a right reset torque under the action of the left elastic member 34 or the left and right elastic members 34 and 35.

[0033] Further, referring to the accompanying drawings Figure 9 And 10 The shell 1 is further provided with a ground plug 7 which can be turned and stored in a surface groove 100, the base of the ground plug 7 is pivotally connected with the shell 1, and a wedge-shaped groove 70 is arranged in the bottom of the base and faces inward, the shell 1 is provided with a support protrusion 12 located at the slot opening of the wedge-shaped groove 70, the support protrusion 12 is configured to be embedded into the wedge-shaped groove 70 when the ground plug 7 is turned up, so as to provide better support force for the ground plug 7 when it is turned up, and avoid easy falling. According to the specification requirements of the plug, the ground plug 7 can be used with a turning plug 21 or a push-out plug 22, and in this embodiment, the ground plug 7 is designed to be used with a British standard push-out plug 22.

[0034] Further, the push-out plug 22 is provided with push-out keys 221 on both sides, which are located outside the shell 1 and connected with the base of the push-out plug 22 in the shell 1 through the stroke groove 13 on the shell 1, and the common force of the two push-out keys 221 can prevent the push-out plug 22 from being deviated due to single side force when it is pushed out, avoiding the situation of push-out jamming.

[0035] The above preferred embodiments should be regarded as examples of the embodiments of the application, and any technical deduction, replacement, improvement, etc. similar to or based on the embodiments of the application should be regarded as the protection scope of the patent.
