After searching, the patent with the announcement number "CN203983560U" discloses a power conversion socket, which can limit the socket itself to only one set of pins through a limit structure, thereby avoiding safety hazards during use. Similarly, the applicant has also designed a new type of convertible socket and filed the following application. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a novel convertible socket.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new type of convertible socket, including a top seat and a bottom shell, the left side and the front side of the bottom shell each have a pushable pin assembly; a limit plate is inserted into the bottom shell, and actuating slopes are formed on both sides of the limit plate corresponding to the two groups of pin assemblies, and the driving cooperation between the actuating slope and the driving part of the pin assembly can make the limit plate itself translate to the left and right accordingly; when the limit plate is translated to the end position by any one group of pin assemblies and is resisted by its driving part, the other group of pin assemblies cannot be pushed because its own driving part is blocked by the limit plate.

[0005] Preferably, the pin assemblies formed on the left side and front side of the bottom shell are pin assembly I and pin assembly II, and their driving parts are correspondingly driving part I and driving part II. The leftward translation of the limit plate is driven by pin assembly I, and the rightward translation is driven by pin assembly II.

[0006] Preferably, the pin assembly I includes a pin I and an actuator I, a driving part I is formed on the pin I, and the actuator I which can be pressed to elastically slide relative to the pin I is formed with a positioning point I corresponding to the upper positioning groove I and the lower positioning groove I of the bottom shell.

[0007] Preferably, the top seat and the bottom shell are formed with an upper hook I and a lower hook I corresponding to the pin assembly I. When the pin assembly I is pushed up and down to the end position, the upper hook I and the lower hook I can stop it accordingly.

[0008] Preferably, the pin assembly II includes a pin II and an actuator II, a driving part II is formed on the pin II, and the actuator II which can be pressed to elastically slide relative to the pin II is formed with a positioning point II corresponding to the upper positioning groove II and the lower positioning groove II of the bottom shell.

[0009] Preferably, the top seat and the bottom case are respectively formed with an upper hook II and a lower hook II corresponding to the pin assembly II. When the pin assembly II is pushed up and down to the end position, the upper hook II and the lower hook II can latch it accordingly.

[0011] Preferably, guide rods are arranged in the bottom case corresponding to two groups of pin assemblies.

[0012] Preferably, the bottom case is provided with a metal plate connected to the top seat. When any one group of pin assemblies is pushed down, the elastic piece provided thereon can be in mutual abutment with the metal plate.

[0013] Preferably, a turntable is rotationally limited on the outer bottom surface of the bottom case, and the ground pins provided on the turntable can be folded and retracted or flipped and opened at the bottom case.

[0014] Compared with the prior art, the utility model has at least the following advantages:

[0015] 1. The limiting plate can play a role in limiting the pin assembly, ensuring that only one group of pin assemblies can be pushed outwards;

[0016] 2. The ground pins outside the socket can be combined with two groups of pin assemblies to form pin assemblies of other specifications;

[0017] 3. The overall volume of the socket is smaller, which is convenient for users to carry when going out. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 - 11 shown: A new type of convertible socket includes a top seat 1 and a bottom shell 2 that are spliced and combined with each other. The top seat 1 with USB and type-c ports has circuit components such as a circuit board. The hardware plate 3 in the bottom shell 2 is connected to the circuit board. A set of pin assemblies are respectively arranged on the left side and the front side of the bottom shell 2, namely the pin assembly Ⅰ 4 as a European standard pin and the pin assembly Ⅱ 5 as a US standard pin. Both sets of pin assemblies can be pushed downward to expose their corresponding pins outward from the bottom shell 2.

[0032] Further, a limiting groove 201 is formed inside the bottom case 2, and a limiting plate 6 is inserted into the limiting groove 201. Actuating slopes 601 are formed on both sides of the top of the limiting plate 6. The pin assembly I 4 and the pin assembly II 5 are respectively provided with a driving part I 411 and a driving part II 511 corresponding to the actuating slope 6. During the process of the pin assembly I 4 being pushed downward, the limiting plate 6 can be pushed to the left end of the limiting groove 201 and abutted against it by means of the driving part I 411. At this time, since the driving part II 511 of the pin assembly II 5 is blocked, the pin assembly II 5 cannot be pushed downward. Similarly, when the pin assembly II 5 is pushed downward, the limiting plate 6 will be pushed to the right end of the limiting groove 201 and abutted against it, and the pin assembly I 4 cannot be pushed downward either.

[0033] Further, the pin assembly I 4 includes a pin I 401 slidably sleeved on a set of guide rods 7 provided on the bottom case 2. The driving part I 411 is formed on the pin I 401. An actuator I 402 is arranged on the top surface of the pin I 401. One end of the actuator I 402 is elastically connected to the pin I 401 through a spring, and the other end is formed with a pressing head I 412 passing through the left chute I 202 of the bottom case 2. At the same time, upper positioning grooves I 203 and lower positioning grooves I 204 are formed on the inner wall of the bottom case 2 at the upper and lower positions on its left side corresponding to the actuator I 402. The actuator I 402 can be abutted against the upper positioning groove I 203 or the lower positioning groove I 204 through the positioning point I 422 formed thereon, so as to maintain its own and the positioning of the pin I 401.

[0034] Specifically, since the actuator I 402 is only abutted against the upper positioning groove I 203 or the lower positioning groove I 204 through the elastic action of the spring, to a certain extent, it may not be stable and is prone to loosening. Therefore, the top seat 1 and the bottom case 2 are also respectively provided with an upper hook I 101 and a lower hook I 205 corresponding to the pin assembly I 4. When the pressing head I 412 of the actuator I 402 is pressed, the actuator I 402 and the pin I 401 can be disengaged from the hook body, so as to move up and down. On the contrary, when the spring returns to its original state, the hook body can hook the actuator I 402, so as to maintain the overall stability of the pin assembly I 4.

[0035] Further, the pin assembly II 5 is generally the same in structure as the pin assembly I 4, that is, it also has a pin II 501 and an actuator II 502 combined by a spring. Among them, the pin II 501 with the driving part II 511 is slidably sleeved on another set of guide rods 7 of the bottom case 2. The pressing head II 512 of the actuator II 502 passes through the front chute II 206 of the bottom case 2. Upper positioning grooves II 207 and lower positioning grooves II 208 are formed on the inner wall of the bottom case 2 at the upper and lower positions on its front side corresponding to the actuator II 502 for positioning and cooperating with the positioning point II 522 of the actuator II 502. Of course, the top seat 1 and the bottom case 2 are also respectively provided with an upper hook II 102 and a lower hook II 209 corresponding to the pin assembly II 5.

[0036] Furthermore, elastic pieces 301 are installed on the pins Ⅰ401 of the pin assembly Ⅰ4 and the pins Ⅱ501 of the pin assembly Ⅱ5. Under normal conditions, the elastic pieces 301 are separated from the metal plate 3 of the bottom shell 2. When the pin assembly Ⅰ4 or the pin assembly Ⅱ5 is pushed downward, the elastic pieces 301 thereof can contact the metal plate 3, thereby forming a closed circuit to supply power to the circuit board of the top seat 2.

[0037] Furthermore, a vertical frame 103 is inserted into the top seat 2 in the bottom shell 1. The turntable 801 embedded in the bottom surface of the bottom shell 2 can cooperate with the vertical frame 103 to realize 90° limit rotation of itself. A ground-level pin 8 is folded on the turntable 801. Under normal conditions, the ground-level pin 8 is received into the slit on the side of the bottom shell 2. After it is dug out and unfolded, through the rotation of the turntable 801, the ground-level pin 8 can be combined with the pin assembly Ⅰ4 serving as a European standard pin to form a British standard pin.

[0038] Furthermore, the pin Ⅱ501 of the pin assembly Ⅱ5 serving as a US standard pin mainly includes a foot frame and a pin. The pin is rotatably inserted on the foot frame and supported by a spring. The hole opened in the bottom shell 2 to allow the pin to pass through is a limit rotation hole. After the two pins are rotated, the pin assembly Ⅱ5 and the above-mentioned ground-level pin 8 are combined to form an Australian standard pin.

[0039] As described above, for a conversion socket with multiple push-out pins, it should be ensured that after one set of pins is pushed out, the other pins cannot be pushed out, so as to avoid potential safety hazards. Although the patent "CN203983560U" can solve this problem, the different pins are actually independent of each other, resulting in a too complex internal structure of the socket, a relatively large overall volume of the socket, and inconvenient carrying. Compared with it, the socket of the present design only has two sets of push-out pins inside. The two sets of pins can be combined with the foldable ground-level pins outside the socket to form other pins of different specifications. Since the internal structure of the socket is relatively simple, the overall volume is more compact, and it is more convenient for users to carry when going out.

[0040] It can be understood that the present utility model is described through some embodiments. As is known to those skilled in the art, without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
