Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

The socket is a common electronic device, and is used for plugging a plug of an electrical appliance so as to supply power to the electrical appliance.

For flexibly adjusting the direction of the jacks of the socket, in the related art, a rotary socket mainly comprises a rotary mechanism and a plug bush module, wherein the rotary mechanism comprises a rotary cylinder and a base, the base is fixed on a carrier, the rotary cylinder is rotatably connected with the base, the jacks are located on the wall of the rotary cylinder, and the plug bush module is located in the rotary cylinder and is arranged in one-to-one correspondence with the jacks. When the electric appliance socket is used, the base is kept fixed, and the direction of the jack is adjusted by rotating the rotary cylinder, so that the electric appliance socket is suitable for electric appliances in different directions.

However, after the rotary drum rotates to a proper position, the rotary drum and the base are positioned only by friction force, unnecessary deflection is easy to occur under the action of external force, and the reliability is poor.

In order to solve the above technical problem, an embodiment of the present disclosure provides a receptacle, and fig. 1 is a schematic structural diagram of the receptacle, referring to fig. 1, the receptacle includes a rotation mechanism 100 and a plurality of jack modules 200.

The rotating mechanism 100 includes a first rotating cylinder 1 and a second rotating cylinder 2, the cylinder wall of the first rotating cylinder 1 has a plurality of insertion holes 300, the insertion holes 300 are sequentially arranged at intervals along the length direction of the first rotating cylinder 1, and the cylinder wall of the second rotating cylinder 2 has a cable through hole 400. The plurality of plug bush modules 200 are located in the first rotary cylinder 1, the plug bush modules 200 correspond to the insertion holes 300 one by one, and the plurality of plug bush modules 200 are respectively opposite to the corresponding insertion holes 300.

When the orientation of the insertion hole 300 needs to be adjusted, the first rotary cylinder 1 is rotated, so that the insertion hole 300 can be rotated together with the first rotary cylinder 1 until the insertion hole is moved to a proper orientation. After the rotation is finished, the first rotary barrel 1 and the second rotary barrel 2 can be locked in position, so that the orientation of the insertion hole 300 can be kept, and unnecessary deflection is avoided.

That is, the embodiment of the present disclosure provides the rotating mechanism 100, in which the first rotating cylinder 1 and the second rotating cylinder 2 can be locked in position. Fig. 2 is an exploded view of the rotating mechanism 100, and how the rotating mechanism 100 achieves positioning locking between the first rotary cylinder 1 and the second rotary cylinder 2 is described below with reference to fig. 2.

In the present embodiment, the end of the first rotary drum 1 is rotatably sleeved outside the end of the second rotary drum 2, and the rotation axis of the first rotary drum 1 is coaxial with the rotation axis of the second rotary drum 2. The end part of the second rotating cylinder 2 close to the first rotating cylinder 1 is provided with a plurality of grooves 21, the plurality of grooves 21 are all positioned in the first rotating cylinder 1, and the rotating axes of the second rotating cylinder 2 are used as the axial circumference and are sequentially arranged at intervals.

The rotating mechanism 100 further comprises an elastic ring 3, the elastic ring 3 comprises a ring body 31 and a protrusion 32, the ring body 31 is located in the first rotating cylinder 1 and connected to the ring body 31, the ring body 31 is coaxial with the rotating axis of the first rotating cylinder 1, the ring body 31 comprises a first side surface 31a and a second side surface 31b which are opposite, the first side surface 31a of the ring body 31 is connected to the end portion of the first rotating cylinder 1 close to the second rotating cylinder 2, the protrusion 32 is located on the ring body 31 and protrudes towards the second side surface 31b of the ring body 31, and the protrusion 32 is used for being clamped in the groove 21.

If the socket needs to be rotated, the first rotary cylinder 1 and the second rotary cylinder 2 are relatively rotated, so that the elastic ring 3 rotates together with the first rotary cylinder 1 relative to the second rotary cylinder 2, namely relative to the circumferentially arranged grooves 21 at the end of the second rotary cylinder 2.

At the start of rotation, the projection 32 snaps into the recess 21. In the process of rotation, because the elastic ring 3 has elasticity, the protrusion 32 overcomes the elasticity and generates elastic deformation after being pressed, so that the protrusion 32 can smoothly move from the bottom of the groove 21 to the top of the groove 21 and further move into another adjacent groove 21. After the rotation is finished, the elastic potential energy of the elastic ring 3 will be released under the effect of the elastic force, so that the protrusion 32 can be again snapped into the nearest groove 21, thereby completing the positioning between the first rotary cylinder 1 and the second rotary cylinder 2.

That is to say, utilize the cooperation of arch 32 and recess 21, can effectually fix a position the locking to first rotatory section of thick bamboo 1 and second rotatory section of thick bamboo 2, improved the location reliability of socket after the rotation.

As can be seen from the foregoing, the elastic ring 3 plays a key role in achieving the positioning and locking between the first rotary cylinder 1 and the second rotary cylinder 2, and the elastic ring 3 will be further described below.

Fig. 3 is a schematic diagram of the fit between the elastic ring 3 and the groove 21, and referring to fig. 3, in this embodiment, the outer surface of the protrusion 32 facing the groove 21 is an arc surface, the inner surface of the groove 21 facing the protrusion 32 is an arc surface, and the inner surface of the groove 21 matches with the outer surface of the protrusion 32.

Because the outer surface of the protrusion 32 and the inner surface of the groove 21 are both arc surfaces, the protrusion 32 can slide to the top of the groove 21 from the bottom of the groove 21, and the protrusion 32 is prevented from being stuck in the groove 21, which affects the normal rotation between the first rotary cylinder 1 and the second rotary cylinder 2.

Optionally, the number of the protrusions 32 is at least two, the protrusions 32 are arranged at intervals along the circumferential direction of the ring body 31, and each protrusion 32 is simultaneously clamped in the groove 21.

As the number of the protrusions 32 increases, the assembling stability between the elastic ring 3 and the protrusions 32 increases, and the elastic force to be overcome by the relative rotation between the first rotary cylinder 1 and the second rotary cylinder 2 increases. Of course, the number of the protrusions 32 can be adjusted as needed, and the disclosure is not limited thereto.

Fig. 4 is a schematic view of the internal structure of the rotating mechanism 100, and the first rotary cylinder 1 is partially cut away in fig. 4 to clearly show the internal structure of the rotating mechanism 100. Referring to fig. 4, in the present embodiment, the first rotary cylinder 1 includes a first cylinder body 11, an inner flange 12, and a snap ring 13. The first cylinder body 11 comprises a first end close to the second rotary cylinder 2 and a second end far away from the second rotary cylinder 2, the inner flange 12 and the clamping ring 13 are both positioned in the first cylinder body 11 at a position close to the first end, the clamping ring 13 is positioned between the inner flange 12 and the first end of the first cylinder body 11, and the side surface of the inner flange 12 close to the clamping ring 13 is attached to the ring body 31;

the second rotary cylinder 2 includes a second cylinder body 22 and a catching groove 23. The second barrel 22 comprises a first end close to the first rotary barrel 1 and a second end far away from the first rotary barrel 1, the clamping groove 23 is located on the outer peripheral wall of the second barrel 22 and extends in the circumferential direction of the shaft by taking the rotation axis of the second rotary barrel 2 as the axis, the clamping ring 13 is rotatably inserted into the clamping groove 23, and the grooves 21 are located at the first end of the second barrel 22.

In the above implementation, the first barrel 11 is a main structure of the first rotary barrel 1, and when the rotary mechanism 100 is applied to a socket, the first barrel 11 is used for accommodating the plug and socket module 200. Both the inner flange 12 and the snap ring 13 are connected within the first barrel 11. The inner flange 12 is used for providing a mounting base for the elastic ring 3, so as to realize the connection of the elastic ring 3 in the first rotary cylinder 1, and the elastic ring 3 can rotate together with the first rotary cylinder 1. The clamping ring 13 is rotatably clamped in the clamping groove 23 to realize the rotatable assembly between the first rotary drum 1 and the second rotary drum 2. The second cylinder 22 is a main structure of the second rotary cylinder 2, and the second cylinder 22 is used for accommodating the cable when the rotary mechanism 100 is applied to the socket. Each groove 21 is arranged at an end of the second cylinder 22 so that each groove 21 can rotate together with the second rotary cylinder 2.

The fitting relationship between the elastic member and the first rotary cylinder 1 will be described below.

Fig. 5 is a schematic view of the internal structure of the rotating mechanism 100, and fig. 5 is a top view of fig. 4. In order to better show the internal structure of the rotation mechanism 100, a part of the first cylinder 11 is cut away in a direction perpendicular to the axis of the first cylinder 11. Referring to fig. 5, in the present embodiment, the first rotating cylinder 1 further includes a relief opening 14, the relief opening 14 is located on the inner flange 12 and penetrates through two opposite side surfaces of the inner flange 12, and the protrusion 32 is opposite to the relief opening 14.

Because the inner flange 12 is attached to the ring body 31, the offset opening 14 is formed in the inner flange 12, and the offset opening 14 is opposite to the protrusion 32, so that a moving space can be provided for the protrusion 32, and the protrusion 32 can smoothly move between the grooves 21.

It will be readily appreciated that the size of the relief opening 14 determines the spring force that the projection 32 needs to overcome during movement. The smaller the size of the relief opening 14, the smaller the distance between the edge of the relief opening 14 and the protrusion 32, and the smaller the moment arm, so that the protrusion 32 needs to overcome the greater the elastic force during movement. Conversely, the larger the size of the relief opening 14, the greater the distance between the edge of the relief opening 14 and the protrusion 32, and the greater the moment arm, so that the protrusion 32 needs to overcome less spring force during movement. That is, by adjusting the size of the relief opening 14, it is possible to adjust the elastic force that the protrusion 32 needs to overcome during the movement, thereby adjusting the torque for rotating the first rotary cylinder 1 and the second rotary cylinder 2.

It should be noted that, although the offset opening 14 in fig. 5 is a through hole penetrating through the inner flange 12, in other embodiments, the offset opening 14 may also be a blind hole not penetrating through the inner flange 12, and only needs to provide enough space for the movement of the protrusion 32, which is not limited by the present disclosure.

With continued reference to fig. 5, in the present embodiment, the first rotary cylinder 1 further includes a slot 15, and the slot 15 is located on the inner flange 12 and penetrates through two opposite sides of the inner flange 12. The elastic ring 3 further comprises an inserting piece 33, the inserting piece 33 is connected with the first side surface 31a of the ring body 31, and the inserting piece 33 is inserted into the slot 15.

By inserting the insertion tabs 33 into the insertion slots 15, a secure connection between the elastic ring 3 and the inner flange 12 can be achieved. It will be readily appreciated that in order to ensure a secure fit of the insert 33 within the slot 15, there is an interference fit between the insert 33 and the slot 15.

Illustratively, the number of the insertion pieces 33 is two, the number of the insertion slots 15 is also two, the two insertion pieces 33 are arranged oppositely, and the two insertion pieces 33 are respectively inserted into the corresponding insertion slots 15, so as to further improve the connection stability between the elastic ring 3 and the inner flange 12.

Alternatively, the elastic ring 3 is a one-piece metal structure, i.e., the ring body 31, the protrusion 32 and the insert 33 are a one-piece structure. For the elasticity of the plate-shaped elastic ring 3, the elastic member is made of a metal material with good elasticity, such as spring steel, and the disclosure does not limit this.

In the present embodiment, the first cylinder 11 includes two half cylinders, which are coaxially arranged and detachably mounted together. It will be readily appreciated that in this case, the inner flange 12 and snap ring 13 are likewise of corresponding semi-annular configuration, and that the inner flange 12 and snap ring 13 can be formed simultaneously when the two half-cylinders are fitted together.

The fitting relationship between the elastic member and the second rotary cylinder 2 will be described below.

Referring to fig. 4 again, in the present embodiment, the second rotary drum 2 further includes a positioning boss 24, an end of the positioning boss 24 is connected to the first end of the second drum 22 and is located in a circular ring enclosed by the plurality of grooves 21, and the positioning boss 24 is coaxial with the rotation axis of the second rotary drum 2. The ring body 31 is rotatably sleeved outside the positioning boss 24.

Because the positioning boss 24 is located in the circular ring surrounded by the plurality of grooves 21 and is coaxial with the rotation axis of the second rotary cylinder 2, the positioning boss 24 enables the elastic ring 3 sleeved on the positioning boss to be coaxial with the rotation axis of the second rotary cylinder 2, so that the protrusions 32 can rotate along the arrangement direction of the grooves 21 all the time in the rotating process of the elastic ring 3, the protrusions 32 are prevented from being separated from the grooves 21, and the reliability of the rotating mechanism is improved.

Alternatively, the outer peripheral wall of the positioning boss 24 is in clearance fit with the inner peripheral wall of the ring body 31. So design can enough guarantee the normal relative rotation between ring body 31 and the location boss 24, can guarantee again that ring body 31 cup joints firmly on location boss 24.

When the rotating mechanism is applied to the socket, the plug bush module 200 is arranged in the first rotating cylinder 1, the cable is arranged in the second rotating cylinder 2, and the cable is connected with the plug bush module 200. In order to avoid the disconnection between the cable and the socket module 200 caused by over-rotation between the first rotary cylinder 1 and the second rotary cylinder 2, in the present embodiment, the first rotary cylinder 1 further includes a first stopper 16, and the first stopper 16 is connected to the inner wall of the first cylinder 11 and the side of the inner flange 12 away from the snap ring 13. The second rotary drum 2 further comprises a second stop member 25, the second stop member 25 is connected with the end of the positioning boss 24 far away from the second drum body 22, and the second stop member 25 is located on the rotation track of the first stop member 16.

In the above implementation, since the first stopper 16 is connected to the first cylinder 11, the second stopper 25 is connected to the second cylinder 22 through the positioning boss 24, and the second stopper 25 is located on the rotation track of the first stopper 16, when the first and second spin cylinders 1 and 2 relatively rotate, the first stopper 16 also synchronously rotates with respect to the second stopper 25. When the relative rotation of the first rotary cylinder 1 and the second rotary cylinder 2 reaches a certain angle, the first stop member 16 will abut against the second stop member 25, thereby limiting the rotation angle.

It is easily understood that the positions of the first stopper 16 and the second stopper 25 can be adjusted according to actual requirements, and the disclosure does not limit this.

Alternatively, the second cylinder 22 is a conical structure, the smaller diameter end of the second cylinder 22 is rotatably connected to the first cylinder 11, and the larger diameter end of the second cylinder 22 is used for placing on a carrier to avoid toppling.

The rotating mechanism is described above, and other structures of the socket are described below.

Referring again to fig. 1, in the present embodiment, the socket further includes a switch button 500, the switch button 500 is located at an end of the first rotary cylinder 1 far from the second rotary cylinder 2, and the switch button 500 is electrically connected to the plurality of jack modules 200.

In the above implementation manner, the switch button 500 is electrically connected to each plug bush module 200, and is used for controlling the power on/off of each plug bush module 200. Since the switch button 500 is located at the end of the first rotary cylinder 1 far from the second rotary cylinder 2, the switch button 500 is far from the elastic ring 3, the function of the elastic ring 3 is not affected, and the reliability of the rotary mechanism 100 is ensured.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
