[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] refer to Figures 1 to 3 , a plug board, comprising a housing 1, a movable cover 2 and a driving mechanism 3;

[0035] The housing 1 has a certain accommodation space;

[0036] The movable cover 2 is movably disposed on the housing 1 along a first direction D, and the movable cover 2 is provided with a plug hole 21, and the plug hole 21 corresponds to the plug pin 51 of the plug device 5;

[0037] The driving mechanism 3 is disposed inside the housing 1 and is connected to the movable cover 2 so that the movable cover 2 can move along the first direction D;

[0038] The driving mechanism 3 includes a rotating body 31, a rotating shaft 32 and a transmission body 33;

[0039] The rotating body 31 can rotate around the rotating shaft 32, and the rotating shaft 32 can be roughly set at the middle position of the rotating body 31. The A end of the rotating body 31 corresponds to the socket 21, and the B end of the rotating body 31 is drivingly connected to the transmission body 33. The upper end of the transmission body 33 is connected to the movable cover 2; the driving mechanism 3 is used to make the movable cover 2 move from the storage position to the use position along the first direction D as the plug device 5 is inserted, and reset to the storage position as the plug device 5 is pulled out.

[0040] When the pin 51 of the plug device 5 is inserted into the socket 21, the pin 51 is inserted into the female socket spring piece (not shown in the figure), and the female socket spring piece is movably connected to the A end of the rotating body 31. Therefore, as the pin 51 is inserted, the rotating body 31 is pushed to rotate, and then the transmission body 33 pushes the movable cover 2 upward along the first direction D and moves to the use position. In this way, the pin 51 can be avoided from being exposed and safety is ensured; when the plug device 5 is unplugged, the movable cover 2 can move downward along the first direction D to the storage position, so that the thickness of the entire power strip is reduced, which makes it convenient to store and carry.

[0041] The driving mechanism 3 further comprises a reset member 34, and the reset member 34 is used to make the movable cover 2 move to the storage position in the reverse direction of the first direction D as the plug device 5 is pulled out, thereby realizing the reset movement to the storage position.

[0042] The reset member 34 has various embodiments:

[0043] In the first embodiment, the upper end of the reset member 34 is connected to the movable cover 2, and the lower end of the reset member 34 is connected to the housing 1. Multiple reset members 34 can be provided, and the reset member 34 can be a spring, which is in a free state at the storage position and in a stretched state at the use position. The specific principle is that when the plug device 5 is inserted into the socket 21, the pin 51 pushes the rotating body 31 to rotate, and then the transmission body 33 pushes the movable cover 2 upward along the first direction D and moves to the use position. When in the use position, the pin 51 of the plug device 5 is inserted into the female seat spring sheet and clamped by the female seat spring sheet. At this time, the spring is in a stretched state, but the spring elastic force is not enough to overcome the clamping force of the female seat spring sheet on the pin, that is, the spring elastic force is not enough to restore the movable cover 2; when the plug device 5 is taken out by manpower, the pin 51 is separated from the female seat spring sheet, and the stretched spring is restored to a free state, and the movable cover 2 moves to the storage position in the opposite direction of the first direction D under the action of the spring restoring force.

[0044] In the second embodiment, the upper end of the reset member 34 is connected to the B end, and the lower end of the reset member 34 is connected to the housing 1. A plurality of reset members 34 may be provided, and the reset member 34 may be a spring, which is in a free state in the storage position and in a stretched state in the use position. The principle is the same as that of the first embodiment, except that the position of the spring is different.

[0045] In the third embodiment, the upper end of the reset member 34 is connected to the A end, and the lower end of the reset member 34 is connected to the housing 1. A plurality of reset members 34 may be provided, and the reset member 34 may be a spring, which is in a free state in the storage position and in a compressed state in the use position. The principle is the same as that of the first embodiment, except that the position of the spring is different, and the state of the corresponding spring is also changed from a stretched state to a compressed state.

[0046] refer to Figure 1 and Figure 3 When the movable cover 2 is in the use position, the maximum dimension of the plug board along the first direction D is the first dimension H1;

[0047] When the movable cover 2 is located at the storage position, the maximum dimension of the plug board along the first direction D is the second dimension H2, and the first dimension H1 is greater than the second dimension H2.

[0048] The first dimension H1 is greater than the length K of the pin 51, and the second dimension H2 is less than or equal to the length K of the pin 51, and the second dimension H2 is less than or equal to 24.5 mm. For reference, the length of the pins of conventional plugs is generally in the range of 24.5 to 30.0 mm, so the power strip according to the present application can significantly reduce the height dimension compared to conventional power strips, thereby reducing the space occupied by the entire power strip to improve portability. However, the above values ​​are only examples, and the size of the power strip according to the present application is not limited to the above value range.

[0049] refer to Figure 4 The rotating body 31 rotates around the rotating shaft 32, and the clockwise and counterclockwise rotation angles thereof are the same, and the total rotation angle θ is less than 160°. A rotation angle that is too large will affect the service life of the reset member, i.e., the spring.

[0050] The transmission body 33 and the movable cover 2 can be fixedly connected or integrally formed, which is equivalent to the rotating body 31 directly acting on the movable cover 2, which can save material costs.

[0051] Optional, reference Figure 5 The A end of the rotating body 31 is provided with an inclined surface 35 on one side facing the plug hole 21, and the angle between the inclined surface 35 and the longitudinal center axis of the rotating body 31 is less than 75 degrees. After the plug pin 51 of the plug device 5 is inserted into the female seat spring sheet, the female seat spring sheet contacts the inclined surface 35, so that the plug pin 51 can push the rotating body 31 to rotate more easily.

[0052] Optional, reference Figure 6 The side of the A end of the rotating body 31 facing the insertion hole 21 is provided with a baffle 36, or the side of the A end of the rotating body 31 facing the insertion hole 21 is provided with a groove. The setting of the baffle 36 or the groove makes the A end of the rotating body 31 form a hook shape or a groove cavity shape, which can limit the connection position of the female seat spring piece and the rotating body 31 to a certain extent, and make the female seat spring piece more stably abut against the A end of the rotating body 31.

[0053] refer to Figure 7 , set the distance from the A end of the rotating body 31 to the rotating shaft 32 to L1, set the distance from the B end of the rotating body 31 to the rotating shaft 32 to L2, and set S equal to the ratio of L1 to L2. When different ratios S are set, the movement stroke of the movable cover 2 is different, resulting in different sizes of the second dimension H2 (storage position).

[0054] According to the industry standard, the length K of the pin 51 is about 23.2 mm. S=L1 / L2 is set, and the values ​​shown in Table 1 can be obtained according to the formula H2=D / (2S-1).

[0055] Table 1:

[0056]

[0057]

[0058] It can be seen from Table 1 that when S=0.75, the thickness of the power strip is 46.4mm, which is greater than the thickness of the traditional socket device. Therefore, it is necessary to set the ratio S>0.75 to effectively reduce the thickness of the power strip. Preferably, S≥1. In this way, the thickness H2 of the power strip is equal to or less than 23.2mm, that is, less than the thickness of the traditional socket device of 24.5mm, which is more convenient to store and carry.

[0059] The above disclosure is only some embodiments of the utility model. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the utility model, and these all belong to the protection scope of the utility model.
