Detailed Description

The following description of the embodiments of the present invention will be made more clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It should be noted that all directional indicators (such as top wall, bottom, side) in the embodiments of the present invention are merely used to explain the relative positional relationship, movement, etc. between the components in a particular posture (as shown in the drawings), and if the particular posture is changed, the directional indicators are changed accordingly. Furthermore, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated.

In view of the technical drawbacks of the related art, the present embodiment provides a conversion plug, as shown in fig. 1 to 3, which includes a housing 100. The two opposite side walls of the shell 100 are respectively provided with a pin hole 100a and an extension hole 100b, the pin holes 100a are compatible with pins of a plurality of national specifications, such as pins of national specifications, american specifications, english specifications and the like, and the pins can be inserted into the pin holes 100a to take electricity; the housing 100 is provided with a first sliding frame 200 and a plurality of second sliding frames 300 which are arranged in a staggered manner, and it should be noted that the first sliding frame 200 and the plurality of second sliding frames 300 can both slide back and forth along the pin holes 100a and the extending holes 100b in the housing 100.

The outer side of the housing 100 is provided with a knob 410, and the inner side of the housing 100 is provided with a movable arm 420 in driving connection with the knob 410. The knob 410 and the movable arm 420 may be directly and fixedly connected to each other through a transmission shaft, or may be in transmission connection with each other through a relatively complex transmission connection mechanism (such as a transmission structure formed by matching a plurality of gears).

As shown in fig. 4 to 6, the first slider 200 is selectively connected to one of the plurality of second sliders 300, each of the second sliders 300 has a pin 310 connected thereto, and the specifications of the pins 310 connected to different second sliders 300 are different from each other, for example: in the present embodiment, three second carriages 300 are provided, and pins 310 of the english, american and european specifications are connected to the three second carriages 300, respectively, but not limited thereto.

When the knob 410 is rotated after one of the second sliding frames 300 is connected to the first sliding frame 200, the movable arm 420 rotates in a first direction (e.g., counterclockwise in fig. 7) under the action of the knob 410, so as to push the first sliding frame 200, so that the first sliding frame 200 drives the second sliding frame 300 connected thereto to slide, as shown in fig. 5, an initial position of the first sliding frame 200 is shown, and as shown in fig. 6, a position of the first sliding frame 200 after the knob 410 rotates.

In this process, the pins 310 connected to the second carriage 300 extend to the outside of the housing 100 through the extending holes 100b along with the sliding of the second carriage 300, so that the user can select the pins 310 to be plugged and powered, and then plug the pins 310 out of the housing 100 and then plug and power with an external socket.

In addition, a reset mechanism is provided in the housing 100 for resetting the first carriage 200 and the second carriage 300. Specifically, when knob 410 is rotated in the second direction (clockwise in fig. 7), movable arm 420 no longer applies a force to first carriage 200, and therefore first carriage 200 returns to the original position under the reset action of the reset mechanism, and during that, second carriage 300 also returns to the original position under the reset action of the reset mechanism. In this embodiment, the reset mechanism is used to maintain the original positions of the first carriage 200 and the second carriage 300 in addition to the reset action of the first carriage 200 and the second carriage 300, so as to prevent the first carriage 200 and the second carriage 300 from autonomously moving relative to the housing 100.

It should be noted that the resetting mechanism may be a sleeve spring, a torsion spring, a tension spring, or other mechanisms capable of driving the first carriage 200 and the second carriage 300 to reset, which is not limited herein.

In addition, the first sliding frame 200 may be selectively connected to one of the plurality of second sliding frames 300 in various manners, for example, the first sliding frame 200 is disposed on one side of the housing 100, the plurality of second sliding frames 300 are disposed on the other side of the housing 100 and are spaced along the extending direction of the first sliding frame 200, each of the second sliding frames 300 may also slide in a direction approaching the first sliding frame 200, when a pushing pin is required, the second sliding frame 300 corresponding to the selected pin may be pushed to slide in a direction approaching the first sliding frame 200 so as to be connected to the first sliding frame 200, and the connection may be that the first sliding frame 200 is above the second sliding frame 300, so that the first sliding frame 200 may abut against the second sliding frame 300 below the first sliding frame 200 when sliding toward the extending hole 100b, thereby realizing that the first sliding frame 200 may be selectively connected to one of the plurality of second sliding frames 300 and pushing the pin on the corresponding second sliding frame 300 to extend out of the housing 100;

for another example, the first sliding frame 200 is provided with connection protruding blocks corresponding to the second sliding frames 300 one by one, each connection protruding block can extend to the upper portion of the corresponding second sliding frame 300 under the action of external force, so that the connection protruding block corresponding to the pin to be pushed out is selected to extend to the upper portion of the second sliding frame 300, then the first sliding frame 200 can prop against the corresponding second sliding frame 300 below the connection protruding block to slide downwards when sliding towards the position close to the extending hole 100b, and the first sliding frame 200 can be selectively connected with one of the plurality of second sliding frames 300 and push the pin on the corresponding second sliding frame 300 to extend out of the housing 100. There are many ways in which the first carriage 200 may be selectively coupled to one of the plurality of second carriages 300, and the specific limitation is not set forth herein.

Compared with the related art, in the structure of the conversion plug of the present embodiment, the telescoping processes of the pins 310 with different specifications are all regulated by the same knob 410, and the knob 410 drives the movable arm 420 for telescoping the pins 310 in a rotating manner, so that the housing 100 of the conversion plug only needs to form a connecting hole for the transmission connection between the knob 410 and the movable arm 420 except for the pin hole 100a and the extension hole 100b, and the connecting hole is blocked by the transmission structure between the knob 410 and the movable arm 420, thereby minimizing the through hole structure formed on the conversion plug and reducing the entry of dust and foreign matters in the conversion plug.

With continued reference to fig. 4-6, the first carriage 200 includes an abutment arm 230 for abutting against the movable arm 420 and a slider 220 connected to the abutment arm 230. In this embodiment, the process of pushing the first carriage 200 by the movable arm 420 is actually a process of pushing the abutting arm 230 by the movable arm 420, and driving the slider 220 connected thereto when the abutting arm 230 is pushed.

In this embodiment, in order to facilitate the connection between the first carriage 200 and the second carriage 300, as shown in fig. 7 to 9, the slider 220 is provided with a switching post 221 for connecting to the second carriage 300, and the switching post 221 is connected to the slider 220 in a resettable manner. Specifically, the slider 220 is provided with a through slot for accommodating the switching post 221, and the switching post 221 is connected with the wall of the through slot through a spring, so as to be connected with the slider 220 in a resettable manner. When the transfer post 221 is pushed, the transfer post 221 extends out of the slider 220 and connects with the second carriage 300, thereby connecting the first carriage 200 and the second carriage 300.

As shown in fig. 3 and 11, the abutment arm 230 is formed with a limiting arm 210 on a side abutting against the movable arm 420, and an included angle space between the limiting arm 210 and the abutment arm 230 is used for accommodating a free end of the movable arm 420. When the free end of the movable arm 420 is located in the space between the limiting arm 210 and the abutting arm 230, the rotation of the movable arm 420 is prevented by the limiting arm 210, and on this basis, the acting force applied to the movable arm 420 by the reset mechanism through the first sliding frame 200 and the acting force applied to the movable arm 420 by the limiting arm 210 are offset, so that the movable arm 420 is in a static state, and thus the locking effect of the movable arm 420 is achieved, so that after the knob 410 is released by a user, the movable arm 420 can not rotate and reset by itself, and thus the pin 310 can not retract into the housing 100 even if the pin is exposed to the external acting force after being extended out through the extension hole 100b, and the pin is convenient to plug with an external socket.

Specifically, when it is desired to switch pins 310 of another size, knob 410 is rotated in a second direction (clockwise in fig. 7) to provide a force in the second direction to movable arm 420. In the locked state of movable arm 420, abutting arm 230 restricts the rotation of movable arm 420 only by the force of the return mechanism, and the rotation of movable arm 420 cannot be completely prevented, so when the rotational force in the second direction applied to movable arm 420 by the user through knob 410 is greater than the restriction force of abutting arm 230 to movable arm 420, movable arm 420 slightly pushes abutting arm 230 and releases the restriction of the angle space between restricting arm 210 and abutting arm 230, and then rotates in the second direction, so that the pushing force is no longer applied to abutting arm 230. At this time, the first carriage 200 and the second carriage 300 return to the original positions under the action of the reset mechanism, and at the same time, the transfer post 221 is reset under the action of the spring, so that the first carriage 200 can be separated from the originally connected second carriage 300, and then connected with other second carriages 300, and the pins 310 with other specifications are pushed out of the housing 100 under the action of the movable arm 420.

Since the pins 310 of different specifications of the present embodiment are all extended and retracted by the same knob 410 and locked by the same movable arm 420, it is not necessary to provide an independent locking mechanism on each second carriage 300 to lock the pins 310 after pushing out, and the structure inside the conversion plug is simplified.

With continued reference to fig. 3 and fig. 7 to 9, in the present embodiment, the number of the switching columns 221 provided on the slider 220 is plural, and the plural switching columns 221 are arranged on the slider 220 at intervals. And each second carriage 300 is provided with a transfer hole 320 matched with the corresponding transfer column 221. A plurality of buttons 110 corresponding to the plurality of switching posts 221 are arranged on the outer side of the shell 100, and the buttons 110 are connected with the shell 100 in a resetting manner. The button 110 is used for pushing the adapting post 221, so that a part of the adapting post 221 extends into the adapting hole 320, and the second sliding frame 300 is connected with the sliding block 220.

When the knob 410 is twisted in a state that the adapter post 221 is inserted into the corresponding adapter hole 320 of the second carriage 300 (an external force is required to maintain a portion of the adapter post extending into the adapter hole), the second carriage 300 slides along with the first carriage 200. During the sliding process, one end of the adapting post 221 relatively far from the adapting hole 320 is abutted against the inner side surface of the housing 100, so that a part of the adapting post 221 extending into the adapting hole 320 is not separated from the adapting hole 320, and the connection between the second sliding frame 300 and the first sliding frame 200 is always maintained during the sliding process.

When the first carriage 200 and the second carriage 300 return to the original positions by the reset mechanism, the transfer post 221 is no longer in abutment with the inner side surface of the housing 100, so that the reset occurs, and thus the portion of the transfer post 221 extending into the transfer hole 320 exits the transfer hole 320, so that the first carriage 200 and the second carriage 300 are separated until the other transfer posts 221 are inserted into the corresponding transfer holes 320.

In conjunction with fig. 10, when the first carriage 200 slides, the slider 220 drives the other non-selected switch columns 221 to slide together. In this process, after the non-selected switching post 221 slides along the slider 220 for a certain distance, it is pushed out to the outside of the slider 220 under the abutting action of the inner side surface of the housing 100, but at this time, the slider 220 is already dislocated with the rest of the second sliding frames 300, so that the switching post 221 cannot be inserted into the corresponding switching hole 320 even if it is pushed out from the slider 220, and therefore, the non-selected pins cannot be pushed out of the housing 100.

Further, in order to facilitate the contact between each of the adaptor posts 221 and the inner surface of the housing 100 when sliding along with the slider 220 to maintain the plugging state with the adaptor hole 320, in this embodiment, as shown in fig. 6, a plurality of abutment ribs 120 extending along the sliding direction of the slider 220 are disposed on the inner side of the housing 100. The plurality of abutment ribs 120 are in one-to-one correspondence with the plurality of transfer posts 221. As shown in fig. 7 to 9, in the process that the slider 220 drives the second slider 300 to slide, the abutment rib 120 abuts against the adapting post 221 to prevent the adapting post 221 from resetting, so as to maintain a state that a part of the adapting post 221 extends into the adapting hole 320, and since the abutment rib 120 is convexly arranged on the inner side surface of the housing 100, when the abutment rib 120 abuts against the adapting post 221, the adapting post 221 is inserted into the adapting hole 320 more deeply, thereby improving the connection stability between the second slider 300 and the first slider 200.

With continued reference to fig. 3, the casing 100 is provided with a plurality of button holes 111 arranged in an array, the plurality of button holes 111 are in one-to-one correspondence with the plurality of buttons 110, and the buttons 110 are repositionably embedded in the button holes 111. As shown in connection with fig. 12 and 13, among the plurality of button holes 111, two adjacent button holes 111 are communicated with each other through the first sliding groove, where "adjacent" means that no other button hole 111 is provided between the two button holes 111. The first sliding groove is internally provided with a first limit sliding block 112, one end of two end parts of the first limit sliding block 112 extends into the button hole 111, and the other end of the first limit sliding block is positioned in the first sliding groove. The button 110 pushes away one end of the first limiting slider 112 during the pressing process, so that the other end of the first limiting slider 112 extends into the adjacent button hole 111. The button 110 always pushes the first limit slider 112 to the adjacent button hole 111 in the pressing process, so that the other end of the first limit slider 112 blocks the pressing of the button 110 in the adjacent button hole 111, and the adjacent two buttons 110 are prevented from being pressed simultaneously, so that the situation that two pins 310 with different specifications extend simultaneously is prevented.

With continued reference to fig. 12 and 13, among the plurality of button holes 111, two button holes 111 that are separated from each other are communicated with each other through the second chute, where "separated" means that one or more other button holes 111 may be provided between the two button holes 111, and that the two button holes 111 are separated from each other by the one or more other button holes 111. Wherein, a second limiting slide block 113 is arranged in the second sliding groove, one end of two end parts of the second limiting slide block 113 extends into the button hole 111, and the other end is positioned in the second sliding groove. The button 110 pushes one end of the second limiting slider 113 away during the pressing process, so that the other end of the second limiting slider 113 extends into the spaced button holes 111. The button 110 always pushes the second limit slider 113 to the adjacent button hole 111 in the pressing process, so that the other end of the second limit slider 113 blocks the pressing of the button 110 in the button hole 111, and the two buttons 110 are prevented from being pressed simultaneously, so that two pins 310 with different specifications are prevented from extending simultaneously.

Further, in an alternative example, a first chamfer is provided on a side edge of the button 110 facing the button hole 111. In the pressing process of the button 110, the first chamfer surface is abutted against the end part of the second limit slider 113 or the end part of the first limit slider 112, and under the guiding action of the first chamfer surface, the first limit slider 112 or the second limit slider 113 can be pushed away more conveniently.

Or, in another alternative example, the two ends of the first limit slider 112 face the button 110 and are respectively formed with second chamfer surfaces, and the two ends of the second limit slider 113 face the button 110 and are respectively formed with third chamfer surfaces. In the pressing process of the button 110, the edge of the button 110 is abutted against the second chamfer surface or the third chamfer surface, and the first limit slider 112 or the second limit slider 113 can be pushed away more conveniently under the guiding action of the second chamfer surface or the third chamfer surface.

With continued reference to fig. 3 and fig. 7 to 9, in order to facilitate the installation of the parts of the patch plug, the housing 100 includes a bottom shell 101 and an upper cover 102, the upper cover 102 is used for covering the opening of the bottom shell 101, the pin holes 100a are formed in the upper cover 102, and the protruding holes 100b are formed in the bottom wall of the bottom shell 101.

In order to facilitate the resetting of the first carriage 200 and each of the second carriages 300 by the resetting mechanism, in the present embodiment, the resetting mechanism includes a plurality of first guide posts 115 and a plurality of second guide posts 116 provided on the inner side surface of the bottom wall of the bottom chassis 101. The first guide post 115 is sleeved with a first compression spring 117, and a plurality of guide holes corresponding to the first guide post 115 are formed in the sliding block 220 and the abutting arm 230 of the first sliding frame 200, and the first guide post 115 is arranged in the guide holes in a penetrating manner, so that the first sliding frame 200 slides along the first guide post 115. Both ends of the first compression spring 117 are respectively abutted against the bottom wall of the bottom case 101 and the first carriage 200, thereby supporting the first carriage 200, and at the same time, resetting the first carriage 200 when the first carriage 200 is displaced.

The second guide post 116 is sleeved with a second pressure spring 118, a plurality of guide holes corresponding to the second guide post 116 are formed in the second sliding frame 300, and the second guide post 116 is arranged in the guide holes in a penetrating mode, so that the second sliding frame 300 slides along the second guide post 116. Both ends of the second compression spring 118 are respectively abutted against the bottom wall of the bottom case 101 and the second sliding frame 300, so that the second sliding frame 300 is supported, and when the second sliding frame 300 is displaced, a resetting effect is exerted on the second sliding frame 300.

With continued reference to fig. 3 and 13 and fig. 14, a plug board 610 opposite to the pin hole 100a and a conductive rod 620 connected to the plug board 610 are further provided in the housing 100 of the present embodiment. The external pins 310 are connected to the socket plate 610 through the pin holes 100a, thereby forming conductive connection. The conductive rod 620 extends along the moving direction of the first sliding frame 200, a socket groove 630 is formed at an end of the conductive rod 620 relatively far from the socket plate 610, and a socket piece 330 for being plugged with the socket groove 630 is provided at each second sliding frame 300. When the pins 310 protrude to the outside of the housing 100 through the protruding holes 100b, the socket pieces 330 are inserted into the socket grooves 630, so that conductive connection is formed between the pins 310 and the pins of the external electrical device.

Referring to fig. 2 and 3, in some embodiments, a dc outlet 700 is also provided within the housing 100. The housing 100 is provided with a plug hole 100c facing the dc outlet 700, and the dc outlet 700 is exposed to the outside of the housing 100 through the plug hole 100 c.
