[0030] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, top, bottom, side...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0034] In addition, the descriptions involving "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0035] In view of the technical defects existing in the related art, this embodiment provides a pin assembly. Figures 1 to 3 As shown, the pin assembly of this embodiment includes a mounting base 100 , a first pin 210 and a second pin 220 . The first pin 210 and the second pin 220 are respectively connected to the mounting base 100 by being flipped over to extend out or be received in the mounting base 100 .

[0036] Reference Figure 4a and Figure 4b As shown, one end of the first pin 210 connected to the mounting base 100 is provided with a first flip axis 218 for forming a rotational connection with the mounting base 100 and a first connecting axis 211 eccentrically arranged with the first flip axis 218. One end of the second pin 220 connected to the mounting base 100 is provided with a second flip axis 226 for forming a rotational connection with the mounting base 100 and a second connecting axis 221 eccentrically arranged with the second flip axis 226.

[0037] The pin assembly of this embodiment further includes a connecting rod 300. Figure 4a and Figure 4b As shown, both ends of the connecting rod 300 are rotatably connected to the first connecting shaft 211 and the second connecting shaft 221 respectively. When the first pin 210 flips, the connecting rod 300 pulls or pushes the second connecting shaft 221 driven by the first connecting shaft 211, thereby flipping the second pin 220.

[0038] For example, when the first pin 210 is Figure 4a and Figure 4bThe first pin 210 rotates in the clockwise direction (the clockwise / counterclockwise directions in the following description refer to the clockwise / counterclockwise directions in the drawings of the present application). At this time, the first connecting shaft 211 eccentrically arranged with the first flipping shaft 218 rotates in the clockwise direction driven by the first pin 210. During this process, the first connecting shaft 211 applies a force toward the lower left to the connecting rod 300, and the force is transmitted to the second connecting shaft 221 through the connecting rod 300. Since the second connecting shaft 221 is eccentrically arranged with the second flipping shaft 226, the entire second pin 220 rotates in the counterclockwise direction under the action of the above force. In this way, the torque generated during the flipping process of the first pin 210 is transmitted to the second pin 220 through the connecting rod 300 of the connecting shaft eccentrically arranged with the flipping shaft, realizing the structure of synchronous extension or storage of the first pin 210 and the second pin 220.

[0039] In the pin assembly of this embodiment, multiple pins are extended or stored in the mounting seat 100 in a flipped manner, which reduces the possibility of wear or collision deformation of the pins. Moreover, by flipping one of the pins, the remaining pins can be flipped, which facilitates the extension and storage operations of the pins.

[0040] It is understandable that the pin assembly of this embodiment can be applied to electrical devices such as sockets, chargers, electric mosquito coils, flashlights, etc. When an electrical device adopts the pin assembly of this embodiment, when the electrical device is carried, the pins of the electrical device can be stored in the electrical device so as not to protrude from the electrical device, thereby reducing the space occupied by the electrical device and improving the portability of the electrical device.

[0041] Further, refer to Figures 2a to 3 As shown, the mounting base 100 of this embodiment includes a first shell 110 and a second shell 120 that are detachably connected. The second shell 120 is provided with a parallel first receiving groove 102 and a second receiving groove 103 on the side facing away from the first shell 110. The first receiving groove 102 is used to accommodate the first pin 210, and the second receiving groove 103 is used to accommodate the second pin 220. In an optional example, the pin assembly is suitable for two-pin plugging, in which case the first pin 210 is a live pin and the second pin 220 is a neutral pin. Accordingly, one first receiving groove 102 and one second receiving groove 103 are provided respectively. In another optional example, the pin assembly is suitable for three-pin plugging, in which case one first pin 210 can be provided and two second pins 220 can be provided. Among them, the first pin 210 is a ground pin, and the two second pins 220 are a live pin and a neutral pin, respectively. Correspondingly, one first receiving groove 102 is provided, two second receiving grooves 103 are provided, and the first receiving groove 102 is located between the two second receiving grooves 103 .

[0042] Furthermore, the first pin 210 of the present embodiment includes a first rotating seat 213 and a first pin terminal 214 connected to the first rotating seat 213. The first flip axis 218 and the first connecting axis 211 are disposed on the first rotating seat 213, and the first pin terminal 214 includes a first contact end 214a and a second contact end 214b disposed opposite to each other, and the first flip axis 218 is located between the first contact end 214a and the second contact end 214b, so that when the first rotating seat 213 rotates, one of the first contact end 214a and the second contact end 214b will flip toward the outside of the mounting seat 100, and the other will flip toward the inside of the mounting seat 100. In an optional example, the first contact end 214a serves as the external contact end of the first pin 210, and the first contact end 214a serves as the internal contact end of the first pin 210.

[0043] Combination Figures 6a to 6c As shown, a conductive sheet 500 for connecting electricity to a circuit board of an electrical device is provided in the mounting seat 100. When the first rotating seat 213 rotates, the first contact end 214a turns toward the outside of the mounting seat 100, and the second contact end 214b turns toward the inside of the mounting seat 100 and contacts the conductive sheet 500. The current taken by the first contact end 214a connected to the external power source is sequentially transmitted to the circuit board of the electrical device through the first pin terminal 214 and the conductive sheet 500 to complete the power collection.

[0044] Furthermore, in order to keep the first pin 210 in a more stable extended state and retracted state, Figure 5 as well as Figures 6a to 6c As shown, the outer periphery of the first rotating seat 213 is configured with a first clamping groove 215 and a second clamping groove 216, and the second housing 120 is provided with a first clamping elastic sheet 121, which is used to cooperate with the first clamping groove 215 and the second clamping groove 216 to lock the first pin 210 when the first pin 210 is extended or stored. Figure 6a As shown, when the first plug pin 210 is in the storage state, the first engaging groove 215 engages with the first engaging spring 121, thereby limiting the outer flipping movement of the first plug pin 210, so that the first plug pin 210 can maintain a stable storage state. Figure 6c As shown, when the first plug pin 210 is in the extended state, the second engaging groove 216 engages with the first engaging elastic piece 121, thereby limiting the inner flipping movement of the first plug pin 210, so that the first plug pin 210 can maintain a stable extended state.

[0045] Further, in order to facilitate the removal of the first pin 210, Figure 3 and Figure 4aAs shown, the first pin 210 is also provided with a first connecting rod 212 spaced apart from the first connecting shaft 211, that is, the first connecting rod 212 is also eccentrically arranged with respect to the first flip shaft 218. The first housing 110 is also provided with a second connecting rod 111, and a tension spring 400 is connected between the first connecting rod 212 and the second connecting rod 111. Figures 6a to 6c The specific function of the tension spring 400 will be described.

[0046] When the first pin 210 is in the storage state, the tension spring 400 is in a stretched state, thereby applying a force to rotate the first pin 210 counterclockwise, so that the first pin 210 maintains a stable storage state. When the user flips out the first pin 210, the distance between the first connecting rod 212 and the second connecting rod 111 gradually increases, so the tension spring 400 will be further stretched until the flip angle of the first pin 210 reaches 45°. When the first pin 210 is flipped 45°, the tension spring 400 is in the maximum stretched state. After that, when the first pin 210 continues to flip to reach the fully extended state, the tension spring 400 will gradually shrink due to the gradual reduction in the distance between the first connecting rod 212 and the second connecting rod 111. When the first pin 210 is flipped 90°, that is, when the first pin 210 is in the fully extended state, the tension spring 400 is in the minimum contracted state. Since the tension spring 400 in the contracted state exerts a force on the first plug pin 210 to rotate clockwise, the first plug pin 210 is kept in a stable extended state.

[0047] Furthermore, combined with Figures 6a to 6c As shown, in order to prevent the elastic force of the tension spring 400 from being too large, resulting in the problem of injuring the user's fingers when the first plug pin 210 is turned out, the outer periphery of the first rotating seat 213 is also constructed with a third clamping groove 217. The third clamping groove 217 is located between the first clamping groove 215 and the second clamping groove 216, so that when the first plug pin 210 rotates to a preset angle, the third clamping groove 217 is engaged with the first clamping elastic sheet 121, so that when the first plug pin 210 is quickly turned out under the action of the larger tension of the tension spring 400, the turning speed of the first plug pin 210 is slowed down, thereby preventing the first plug pin 210 from injuring the user's fingers. It can be understood that the size of the preset angle for the third clamping groove 217 to engage with the first clamping elastic sheet 121 can be appropriately adjusted according to actual needs.

[0048] Continue to refer to Figures 3 to 4bAs shown, the second pin 220 of this embodiment includes a second rotating seat 222 and a second pin terminal 223 connected to the second rotating seat 222. The second flip axis 226 and the second connecting axis 221 are arranged on the second rotating seat 222, and the second pin terminal 223 includes a third contact end 223a and a fourth contact end 223b arranged opposite to each other, and the second flip axis 226 is located between the third contact end 223a and the fourth contact end 223b, so that when the second rotating seat 222 rotates, one of the third contact end 223a and the fourth contact end 223b will flip toward the outside of the mounting seat 100, and the other will flip toward the inside of the mounting seat 100. In an optional example, the third contact end 223a serves as the external contact end of the second pin 220, and the fourth contact end 223b serves as the internal contact end of the second pin 220.

[0049] Combination Figure 7a and Figure 7b As shown, a conductive sheet 500 for connecting electricity to a circuit board of an electrical device is provided in the mounting seat 100. When the second rotating seat 222 rotates, the third contact end 223a turns toward the outside of the mounting seat 100, and the fourth contact end 223b turns toward the inside of the mounting seat 100 and contacts the conductive sheet 500. The current taken by the third contact end 223a connected to the external power source is sequentially transmitted to the circuit board of the electrical device through the second pin terminal 223 and the conductive sheet 500 to complete the power collection.

[0050] Furthermore, in order to keep the first pin 210 in a more stable extended state and retracted state, Figure 5 as well as Figure 7a and Figure 7b As shown, the outer periphery of the second rotating seat 222 is configured with a fourth clamping groove 224 and a fifth clamping groove 225, and the second housing 120 is provided with a second clamping elastic piece 122, which is used to cooperate with the fourth clamping groove 224 and the fifth clamping groove 225 to lock the second pin 220 when the second pin 220 is extended or stored. Figure 7a As shown, when the second plug pin 220 is in the storage state, the fourth engaging groove 224 engages with the second engaging spring 122, thereby limiting the outer flipping movement of the second plug pin 220, so that the second plug pin 220 can maintain a stable storage state. Figure 7b As shown, when the second plug pin 220 is in the extended state, the fifth engaging groove 225 engages with the second engaging elastic piece 122 to limit the inward turning movement of the second plug pin 220 , so that the second plug pin 220 can maintain a stable extended state.

[0051] Further, continue to refer to Figure 2a and Figure 2bAs shown, in order to prevent the first pin 210 and the second pin 220 from over-turning during the extension process, a limiting portion 101 is provided on the side of the first housing 110 facing away from the second housing 120, and the limiting portion 101 is used to limit the turning angle of the first pin 210 and the second pin 220. Specifically, during the process of extending the first pin 210 and the second pin 220, the first pin 210 and the second pin 220 abut against the limiting portion 101, thereby limiting the rotation angle of the first pin 210 and the second pin 220, so that the first pin 210 and the second pin 220 can only turn at a preset angle (such as 90°) during the extension process, thereby ensuring the normal use of the pin assembly.

[0052] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
