It should be noted that the socket includes a functional component inside, the functional component includes a plug bush assembly, and the plug bush assembly includes a plug bush and a protection door located at the top of the plug bush, so in the embodiment of the present invention, the whole body formed by the plug bush and the protection door in the plug bush assembly is collectively referred to as the plug bush assembly.

In order to solve the problem that the plug is difficult to be pulled out from the socket at present, particularly to a socket of an extension cord, which makes the pulling out of the plug laborious and even requires two hands of a user to operate the plug, an embodiment of the present invention provides a socket, as shown in fig. 1, fig. 3, or fig. 11, the socket includes: the face cover 1, the base 2, the plug bush component 3, the movable cover component 4 and the telescopic piece 5; the face cover 1 and the base 2 are connected and matched to form a socket cavity, and the plug bush component 3 and the telescopic piece 5 are arranged in the socket cavity.

The face cover 1 is provided with a through hole 10, the movable cover part 4 is provided with a jack 40, the movable cover part 4 is movably connected with the face cover 1 through the through hole 10, and the movable cover part 4 is configured to allow a plug to be inserted into a plug bush of the plug bush assembly 3 from the jack 40 and to be pressed to move downwards.

The telescopic member 5 includes a pressing structure having a telescopic head 51, the telescopic member 5 is configured such that the telescopic head 51 can be driven to compress by the movable cover member 4 moving downward and locked when the plug is inserted into the socket assembly 3, and the telescopic head 51 can be driven to unlock by the movable cover member 4 moving downward and to drive the movable cover member 4 to move upward when the plug is moved to extend, so that the plug is detached from the socket assembly 3.

The trajectory of the movable cover 4 comprises a top dead center position, a first bottom dead center position and a second bottom dead center position, wherein the socket is at a normal state, the plug is not inserted into the socket, and the movable cover 4 is stabilized at the top dead center position. When the plug is inserted into the socket and the movable cover member 4 is pressed downward, the movable cover member 4 can move from the top dead center position to the first bottom dead center position. When the plug in the power-taking state is continuously pressed, the movable cover member 4 can move from the first bottom dead center position to the second bottom dead center position.

According to the socket provided by the embodiment of the utility model, the movable cover part 4 and the telescopic part 5 are additionally arranged, and the movable cover part 4 is movably connected to the face cover 1 through the through hole 10 on the face cover 1, so that the movable cover part can move up and down relative to the face cover 1. When the plug of the external electrical appliance is inserted into the plug bush assembly 3 from the jack 40 on the movable cover part 4, the plug moving downwards can simultaneously press the movable cover part 4 to move downwards along with the movable cover part and compress the telescopic head 51, and the telescopic head 51 is locked when the plug is inserted in place, so that the plug pin of the plug is stably inserted into the plug bush assembly 3. When the plug is pressed downwards again, the movable cover part 4 moves downwards further, the telescopic head 51 can be driven by the movable cover part 4 moving downwards to release the locking, the telescopic head 51 releasing the locking performs the extending reset movement, and the movable cover part 4 is driven to move upwards to push the plug during the extending movement, so that the plug is smoothly pulled out of the plug bush component 3. It can be seen that by having the telescopic member 5 interact with the movable cover member 4, the power plug can be easily pulled out from the plug bush assembly 3, making the pulling out work of the plug more labor-saving.

All of the telescopic members 5 satisfying the pressing structure described above may be applied to the embodiments of the present invention, and some pressing structures applied to the embodiments of the present invention may include, but are not limited to: a heart-shaped groove type pressing structure, a ratchet wheel type pressing structure or a trunk button type pressing structure.

The push switch is a switch device having a heart-shaped groove type pressing structure or a ratchet type pressing structure, and in some examples, the push switch is used as the extensible member 5, and even if the extensible member 5 is a push switch, a button of the push switch is the extensible head 51.

The button switch not only meets the above functions of the telescopic piece 5, but also has a small volume, and the button switch is used as the telescopic piece 5 related to the embodiment of the utility model, so that the existing devices are effectively utilized, and a new telescopic piece 5 does not need to be additionally manufactured, which is beneficial to simplifying the preparation process of the socket.

In some examples, the housing of the telescopic member 5 is fixed to the face cover 1 or the base 2, for example, the housing of the telescopic member 5 is fixed to the inside of the base 2 by means of screw connection, snap connection, riveting, pin connection, adhesion, and the like.

As shown in fig. 1, the base 2 has a fixing bracket 20, the fixing bracket 20 has a screw hole, and a screw is inserted through a hole in the housing of the extensible member 5 and screwed into the screw hole to fix the housing of the extensible member 5 to the fixing bracket 20. By providing the fixing bracket 20, it is not only advantageous to fix the extensible member 5 in the base 2, but also to be able to control the position of the extensible member 5 in the base 2 at a suitable position, so that it can be conveniently in direct or indirect contact with the movable lid member 4.

In some implementations, referring to fig. 3, the telescopic member 5 is located below the movable lid member 4, the bottom of the movable lid member 4 abuts against or is connected to the telescopic head 51, and the moving direction of the movable lid member 4 is the same as the telescopic moving direction of the telescopic head 51, and both the moving directions are up and down, in which way the telescopic member 5 is arranged in the vertical direction.

Referring to fig. 3, when the movable lid 4 is pressed to move downward by the plug, the retractable head 51 is simultaneously pressed by the movable lid 4 to perform a downward compression movement, so that the plug is smoothly inserted into the socket assembly 3. The plug is pressed again, so that the telescopic head 51 performs an upward extending motion, and the movable cover part 4 also performs an upward returning motion to push the plug to smoothly separate from the plug bush component 3.

In order to ensure that the movable cover 4 does not fall out of the through hole 10 when moving up and down, in some examples, the movable cover 4 has a stop structure 430 thereon, and the stop structure 430 is used for preventing the movable cover 4 from falling out of the through hole 10. The stop structure 430 may be located on the outer wall of the movable cover 4, for example, in a shape of a bump, so as to abut against the bottom wall of the face cover 1 located on the side of the through hole 10.

Some suitable specific structures of the movable cover member 4 are exemplified in connection with the above-described embodiments, as shown in fig. 4, the movable cover member 4 includes: a first cover portion 411 and a first transmission portion 412, the first transmission portion 412 being connected to a bottom portion of the first cover portion 411. The first lid portion 411 is vertically movably inserted through the hole 10; the first transmission part 412 abuts against or is connected to the extendable head 51 of the extendable member 5.

When the retractable head 51 is unlocked and extends upwards, the movable cover 4 is pushed upwards together until the movable cover 4 returns to the top dead center position, and at this time, the top wall of the first transmission part 412 of the movable cover 4 abuts against the bottom wall of the face cover 1, so that the movable cover 4 is stopped at the top dead center position.

The first transmission part 412 has both transmission structure and stop structure 430, which is beneficial to simplify the structure of the movable cover 4.

For example, the first transmission part 412 includes, but is not limited to, a circular plate shape, a rectangular ring plate shape, and the like, and further, the area of the region of the first transmission part 412 in contact with the retractable head 51 may be made larger than the area of other regions.

The arrangement of the first transmission part 412 with the above structure on the movable cover member 4 is not only beneficial to simplifying the structure of the movable cover member 4, but also beneficial to simplifying the preparation process of the movable cover member 4, and the movable cover member 4 can be prepared by adopting a simple integral molding process.

In some examples, the first transmission part 412 is connected with the shaft hole of the telescopic head 51, one of the first transmission part 412 and the telescopic head 51 has a fixing shaft 81, and the other has a fixing hole 82, and the fixing shaft 81 is tightly inserted into the fixing hole 82, so as to realize stable connection between the two. For example, as shown in fig. 4, the lower end of the first transmission part 412 is connected to a fixed shaft 81, and as shown in fig. 7, the telescopic head 51 is provided with a fixed hole 82.

In other implementations, the moving direction of the movable cover 4 is perpendicular to the telescopic moving direction of the telescopic head 51, and the movable cover 4 and the telescopic head 51 are switched by a wedge mechanism. The moving direction of the movable lid member 4 is in the up-down direction and the telescopic moving direction of the telescopic head 51 is in the horizontal direction, in such a manner that the telescopic member 5 is arranged in the horizontal direction.

The cam mechanism can convert the downward movement of the movable lid member 4 into the compression movement of the retractable head 51, and convert the extension movement of the retractable head 51 into the upward movement of the movable lid member 4, wherein the directions of the compression movement and the extension movement of the retractable head 51 are in the horizontal direction.

The wedge mechanism has the advantages of high transmission efficiency, simple structure, easiness in manufacturing and the like, and through the wedge mechanism, the plug can be assisted in being pulled out and can be inserted into the plug bush, so that the plug of the plug is more labor-saving and smooth, and the user experience is improved.

In some examples, a cam mechanism is provided between the lower end of the movable cover member 4 and the end of the telescoping head 51 facing the movable cover member 4, the cam mechanism including a first cam surface, and a second cam surface or slider slidably engaged with the first cam surface. For example, the lower end of the movable cover 4 has a first wedge surface, and the end of the retractable head 51 has a slider or a second wedge surface; alternatively, the end of the retractable head 51 has a first cam surface, and the lower end of the movable lid 4 has a slider or a second cam surface.

Illustratively, the plug bush assembly 3, the transmission member 6 and the telescopic member 5 are arranged in sequence in a direction parallel to the face cover 1 within the receptacle cavity. The transmission part 6 only occupies the part of the socket cavity on one side of the plug bush component 3, so that the thickness of the socket cannot be increased, and the functions of assisting in inserting and extracting a plug are achieved.

For the cam mechanism disposed between the second end of the transmission member 6 and the lower end of the movable cover member 4, the cam mechanism comprises a first cam surface 71 and a second cam surface 72, as shown in fig. 5, 6 and 7, the first cam surface 71 is located at the second end of the transmission member 6, and the second cam surface 72 is located at the lower end of the movable cover member 4.

Referring to fig. 7, the first cam surface 71 has an upper end and a lower end, the first cam surface 71 is gradually inclined downward from the upper end to the lower end thereof, and the upper end of the first cam surface 71 is closer to the telescopic head 51 than the lower end thereof. Accordingly, the second cam surface 72 is located at the lower end of the first transmission part 412 of the movable cover 4, the second cam surface 72 has the same inclination direction as the first cam surface 71, the second cam surface 72 also has an upper end and a lower end, and the second cam surface 72 is gradually inclined downward from the upper end to the lower end thereof.

As shown in fig. 5, when the plug is not inserted into the receptacle and the movable cover 4 is at the top dead center position, the first cam surface 71 and the second cam surface 72 are completely in surface contact with each other. As shown in fig. 6, when the plug is inserted into the socket, the plug presses the movable cover 4, so that the movable cover 4 moves downward from the top dead center position to the first bottom dead center position, the second wedge surface 72 moving downward moves along the first wedge surface 71, and then the driving transmission member 6 moves in a direction away from the movable cover 4, and further compresses the retractable head 51, so that the retractable head 51 moves and is locked at the second dead center position, and finally the movable cover 4 moves to the first bottom dead center position, and the lower portion of the first wedge surface 71 abuts against the upper portion of the second wedge surface 72, thereby assisting the insertion of the plug.

When the plug needs to be pulled out of the socket, the plug is pressed again, the movable cover element 4 continues to move from the first bottom dead center position to the second bottom dead center position, the second wedge surface 72 moving downwards moves along the first wedge surface 71, the driving transmission element 6 continues to move in the direction away from the movable cover element 4, and then the retractable head 51 is compressed again, so that the retractable head 51 is unlocked. Subsequently, the first wedge surface 71 moves along the second wedge surface 72, the upper end of the first wedge surface 71 gradually approaches the movable cover 4, the movable cover 4 is driven to move to the top dead center position through the first bottom dead center position, and the plug is pushed to assist in pulling out the plug.

The first end of the transmission member 6 may be abutted against or connected to the retractable head 51, and in order to ensure reliable interaction between the transmission member 6 and the retractable head 51, it is desirable that the transmission member 6 is connected to the retractable head 51.

As a simple and reliable mode, the transmission member 6 is connected with the telescopic head 51 through a shaft hole, one of the transmission member 6 and the telescopic head 51 is provided with a fixed shaft 81, the other is provided with a fixed hole 82, and the fixed shaft 81 is tightly inserted into the fixed hole 82, so that the stable connection between the transmission member 6 and the telescopic head is realized.

For example, as shown in fig. 7, a fixing hole 82 is opened at an end of the telescopic head 51 facing the transmission member 6, and a fixing shaft 81 is connected to a first end of the transmission member 6 facing the telescopic head 51.

The construction of some suitable transmission members 6 will be described by way of example with reference to fig. 8, the transmission members 6 comprising: the plug and socket assembly comprises a main body part 61, a first side part 62 and a second side part 63, wherein the first side part 62 and the second side part 63 are respectively connected with two opposite sides of the main body part 61 and are matched with each other to form a containing cavity, and the containing cavity is used for containing at least part of the plug and socket assembly 3.

First cammed surfaces 71 are provided at the upper ends of the main body portion 61, the first side portion 62 and the second side portion 63, as shown in fig. 8, wherein the length of the first cammed surfaces 71 arranged at the top end of the main body portion 61 is smaller than the length of the first cammed surfaces 71 arranged at the top end of the first side portion 62 and the second side portion 63, the first cammed surfaces 71 arranged at the top end of the main body portion 61 provide only one end portion of the sliding track, and the first cammed surfaces 71 arranged at the top end of the first side portion 62 and the second side portion 63 provide the whole range of the sliding track.

For example, fig. 8 shows that the end of the main body 61 facing the retractable head 51 is connected with a fixing shaft 81, the corresponding end of the retractable head 51 is provided with a fixing hole 82, and the fixing shaft 81 is inserted into the fixing hole 82.

For the containing cavity of the transmission part 6, the containing cavity is communicated up and down, and one end facing the plug bush component 3 is open, so that the plug bush component 3 can enter or leave the containing cavity relative to the transmission part 6. When no plug is inserted into the socket, part of the sleeve assembly 3 is accommodated inside the accommodating cavity of the transmission member 6 to ensure that the first wedge surface 71 on the transmission member 6 is completely abutted against the second wedge surface 72 on the movable cover member 4. When the transmission member 6 is driven away from the sleeve assembly 3 by the movable cover member 4, the sleeve assembly 3 can be removed from the receiving cavity.

In order to make the movement of the transmission member 6 in the horizontal direction smoother, the bottom wall of the transmission member 6 facing the base 2, for example, facing the fixed bracket 20 on the base 2 is provided as a smooth plane, so that the transmission member 6 performs the movement in the horizontal direction along the fixed bracket 20. The bottom wall of the transmission member 6 referred to herein means the bottom walls of the main body portion 61, the first side portion 62, and the second side portion 63.

Further, a reinforcing structure 64 is arranged on the end of the main body part 61 facing away from the telescopic head 51, and the reinforcing structure 64 may be, for example, a plurality of reinforcing ribs (the top ends of the reinforcing ribs are arranged with the first wedge surfaces 71). The structural design of the transmission part 6 enables the internal structure of the socket to be more compact, facilitates the volume miniaturization of the socket and simplifies the preparation process.

In order to ensure that the movable cover 4 does not fall out of the through hole 10 when moving up and down, in some examples, the movable cover 4 has a stop structure 430 thereon, and the stop structure 430 is used for preventing the movable cover 4 from falling out of the through hole 10.
