[0021] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] like Figures 1 to 6 As shown, the adapter socket 100 of this utility model includes a double-gear sliding plug assembly 1, a housing 2, a socket assembly 3, a first connecting terminal (not shown), and a second connecting terminal. The socket assembly 3 is disposed on the upper inner side of the housing 2 for plugging in electrical equipment. The first connecting terminal is disposed in the socket hole of the socket assembly 3 for electrical connection with the electrical equipment, and the second connecting terminal is disposed on the lower inner side of the housing 2. The first and second connecting terminals are electrically connected to each other, that is, the positive terminal of the first connecting terminal is connected to the positive terminal 41 of the second connecting terminal, and the negative terminal of the first connecting terminal is connected to the negative terminal 42 of the second connecting terminal. The double-gear sliding plug assembly 1 is slidably disposed within the housing 2. The dual-gear sliding pin assembly 1 includes a pin base 11, a sliding bracket 12, a rack 13, a pair of gears 14, a pair of contact terminals 15, and a pair of pins 16. The two pins 16 are connected to the sliding bracket 12, and the two contact terminals 15 are respectively connected to the two pins 16. The two gears 14 are pivotally connected to the pin base 11 with their central axes parallel, and are separated by a certain gap. One end of the rack 13 is fixed to the sliding bracket 12, and the other end extends into the gap. The rack 13 has teeth on opposite sides, and the teeth on each side mesh with the gear 14 on that side. The sliding bracket 12 slides relative to the pin base 11, so that the rack 13 and the gears 14 drive each other, and drive the pins 16 to extend and retract relative to the pin base 11. When the pin 16 slides to abut against the pin holder 11, the pin 16 can continue to push the pin holder 11 to slide, causing the pin holder 11 to extend out of the housing 2. When the pin holder 11 and the pin 16 extend out of the housing 2, the two contact terminals 15 are in electrical contact with the positive and negative terminals of the second connection terminal, respectively; when the pin holder 11 and the pin 16 retract into the housing 2, the two contact terminals 15 are separated from the positive and negative terminals 41 and 42 of the second connection terminal, respectively.

[0023] Please see Figure 3 and Figure 6The pin seat body 11 comprises an outer seat body 111 and an inner support 112, the outer seat body 111 is slidingly arranged in the shell 2; the outer seat body 111 is in a cylindrical shape and has a hollow structure inside, and the inner support 112 is fixed in the outer seat body 111; the two gears 14 are pivoted in the inner support 112. Such arrangement makes the gears 14 and the gear racks 13 not occupy more space of the conversion socket 100, and the structure is compact and reasonable, and the volume is small.

[0024] Please also refer to Figure 2 , Figure 3 and Figure 6 , the sliding support 12 is provided with a guide sleeve 12a, and the pin seat body 11 is provided with a guide column 11a; the guide sleeve 12a is slidingly sleeved on the guide column 11a. The pin seat body 11 is provided with a sliding sleeve 11b, specifically, the outer side of the outer seat body 111 is provided with a sliding sleeve 11b, and the inside of the shell 2 is provided with a plurality of sliding columns arranged on the outer periphery of the outer seat body 111, and the sliding sleeve 11b is slidingly sleeved on the sliding columns. The guide column 11a and the sliding column of the embodiment are coaxial and fixed in the shell 2. Through the cooperation of the sliding sleeve 11b and the sliding column and the guide sleeve 12a and the guide column 11a, the pin seat body 11 can stably slide, and the sliding effect is better.

[0025] Again, as Figures 3 to 6As shown, the sliding bracket 12 comprises a first bracket 121 sliding along the sliding direction of the sliding bracket 12, i.e. the extension and retraction direction of the pin 16, and a second bracket 122 arranged on the first bracket 121 and sliding along a direction perpendicular to the sliding direction of the sliding bracket 12. The second bracket 122 is provided with a protruding portion, and the housing 2 is provided with a blocking portion. When the second bracket 122 slides relative to the first bracket 121 so that the protruding portion is dislocated from the blocking portion, the first bracket 121 is unlocked. When the second bracket 122 slides relative to the first bracket 121 so that the protruding portion is reset with the blocking portion, the blocking portion blocks the protruding portion, thereby locking the first bracket 121 and preventing it from sliding. By slidingly arranging the second bracket 122 on the first bracket 121, providing the protruding portion on the second bracket 122, providing the blocking portion in the housing 2, and blocking the protruding portion by the blocking portion, the stroke of the first bracket 121 can be locked, the pin 16 can be prevented from being unexpectedly extended or retracted, and the reliability and safety of use can be improved. Specifically, an elastic member 123 is arranged between the first bracket 121 and the second bracket 122, and the elastic member 123 is a compression spring. The elastic force of the elastic member 123 drives the second bracket 122 to slide relative to the first bracket 121, so that the protruding portion is automatically abutted against the blocking portion. By arranging the elastic member 123, the stroke of the first bracket 121 can be automatically locked, the operation steps are reduced, and the safety of use is ensured. More specifically, the first bracket 121 is provided with a receiving groove 121a, the second bracket 122 is provided with a sleeve column 122a, the first bracket 121 is provided with a first abutting portion 121b, the second bracket 122 is provided with a second abutting portion 122b, the elastic member 123 is arranged in the receiving groove 121a and one end of the elastic member 123 abuts against the first bracket 121 and the other end of the elastic member 123 abuts against the sleeve column 122a, and the elastic force of the elastic member 123 drives the second abutting portion 122b to abut against the first abutting portion 121b. In this way, the structure of the first bracket 121, the second bracket 122 and the elastic member 123 can be more compact and reasonable, and the volume of the converted socket 100 can be reduced.

[0026] In combination Figure 2 And Figure 7As shown, in use, the second support 122 is first pushed to slide relative to the first support 121, at this time, the protruding part is staggered with the blocking part, so that the first support 121 is unlocked, and then the second support 122 is pushed to drive the first support 121 to slide out of the plug base body 11. In this process, the rack 13 and the two gears 14 are in transmission, so that the sliding is more stable. When the sliding support 12 reaches the plug base body 11, continue to push, so that the plug base body 11 extends out of the shell 2. And, at this time, the two contact terminals 15 are respectively in electrical contact with the positive and negative poles 41, 42 of the second connecting terminal, so that the two plugs 16 are respectively in electrical contact with the positive and negative poles of the first connecting terminal. The electrical equipment can be plugged into the socket assembly 3, so as to realize the conversion of conduction.

[0027] Compared with the prior art, the utility model discloses a rack 13 is arranged on the sliding support 12, gear teeth are arranged on the opposite sides of the rack 13, and a pair of center shaft parallel gears 14 are arranged on the plug base body 11 with a certain gap, the rack 13 is arranged on the gap between the two gears 14, so that the two gears 14 can be engaged with the rack 13 at the same time, and the transmission of the rack 13 and the gear 14 is realized.

[0028] The structure of the socket assembly 3, the first connecting terminal and the second connecting terminal involved in the utility model conversion socket 100 is well known to those skilled in the art, and detailed description is not given here.

[0029] The above disclosed is only a preferred embodiment of the utility model, and of course cannot limit the scope of the utility model, so equivalent changes made according to the patent range of the utility model still belong to the range covered by the utility model.
