[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0041] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0042] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0043] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0044] like Figure 1-4 As shown, an embodiment of the utility model provides a power strip, which is used for at least the pin 11 on the external plug 1 to be inserted and connected. The power strip includes a housing 2, a socket 3, a movable part 4, a lifting cover 5, a transmission part 6 and a locking mechanism 7. A receiving cavity is formed inside the housing 2, and an opening 21 connected to the receiving cavity is opened. The socket 3 is arranged in the receiving cavity and is located below the opening 21. A mounting groove is formed in the socket 3, and a spring 31 for clamping the pin 11 is fixedly connected to the bottom of the mounting groove (refer to Fig. 9 ), the spring piece 31 is also used to electrically connect with the pin 11. A movable part 4 is movably arranged in the installation groove for abutting against the pin 11 when the pin 11 is inserted, and at least part of the outer wall of the movable part 4 abuts against the groove wall of the installation groove, so that the movable part 4 is slidably connected with the shell 2. The lifting cover 5 is movably arranged in the opening 21, and can be raised or lowered relative to the shell 2. The transmission member 6 is arranged in the accommodating cavity and is respectively connected to the movable part 4 and the lifting cover 5. The transmission member 6 is used to drive the lifting cover 5 to rise when the pin 11 is inserted and abuts against the movable part 4; or to drive the movable part 4 to rise when the pin 11 is pulled out and the lifting cover 5 falls back. The locking mechanism 7 is arranged between the movable part 4 and the socket 3, and is connected to the movable part 4 and / or the socket 3. The locking mechanism 7 is used to lock the relative position between the movable part 4 and the socket 3 when the pin 11 is connected with the spring piece 31.

[0045] It should be noted that, during the lifting process of the lifting cover 5, the pin 11 is inserted into the lifting cover 5 until it abuts against the movable part 4, and the pin 11 is continued to be inserted and the movable part 4 is driven to fall back. The movable part 4 drives the lifting cover 5 to rise through the transmission part 6 until the pin 11 is connected with the spring 31, and the lifting cover 5 is raised to the maximum displacement and abuts against the external plug 1. At this time, the locking mechanism 7 limits the relative position between the movable part 4 and the socket 3, thereby limiting the movement of the lifting cover 5 through the transmission part 6, thereby preventing the lifting cover 5 from falling back. It can be understood that when the pin 11 is connected with the spring 31, the spring 31 clamps the pin 11, so that the pin 11 cannot be raised, so that the movable part 4 abutting against the pin 11 cannot be raised, thereby hindering the lifting cover 5 from falling back. Therefore, the spring 31 and the locking mechanism 7 work together to limit the lifting cover 5 from falling back. When the spring sheet 31 becomes loose due to long-term use, the clamping force of the spring sheet 31 clamping the pin 11 is reduced, so it is difficult to limit the rise of the movable member 4, so that the lifting cover 5 is easy to fall back when the pin 11 is connected to the spring sheet 31. At this time, the locking mechanism 7 limits the rise of the movable member 4, which can compensate for the reduced clamping force of the spring sheet 31, thereby preventing the lifting cover 5 from falling back.

[0046] In addition, during the falling process of the lifting cover 5, the pin 11 is separated from the spring 31, and the lifting cover 5 is driven by the driving force to fall back, so it falls back, and the movable member 4 is driven to rise through the transmission member 6, until the lifting cover 5 completely falls back to the housing 2, at which time, the top surface of the lifting cover 5 is flush with the top surface of the opening 21. It should be noted that the above-mentioned driving force can be an external force from the user.

[0047] like Fig.10 As shown in some possible embodiments, the lifting cover 5 includes a panel 51 and an extension 52, and the outer edge of the panel 51 is along the pin 11 (reference Figure 3 ) is extended in the direction of insertion to form the above-mentioned extension portion 52. The cross-sectional size and shape of the extension portion 52 are similar to the opening 21 (refer to Figure 3 ) to match the size and shape of the lifting cover 5 with the housing 2 for sliding connection; and to make the gap between the extension 52 and the housing 2 zero, thereby preventing foreign matter from entering the housing 2 through the gap between the extension 52 and the housing 2. Along the direction of insertion of the pin 11, the projection area of ​​the socket 3 is located within the projection area of ​​the extension 52, thereby preventing the extension 52 from interfering with the movement. Optionally, the socket 3 (refer to Figure 2) is slidably connected with the inner wall of the extension portion 52, so that the lifting cover 5 moves more stably when it is raised and lowered, and the space occupied by the lifting cover 5 in the accommodating cavity is reduced, so that the structure is compact. A socket group 511 for inserting the pins 11 is provided on the panel 51, and the socket group 511 is connected to the mounting groove. It can be understood that the socket group 511 can be set to two sockets for matching with a two-pin plug, or it can be set to three sockets for matching with a three-pin plug. This embodiment does not limit the number of sockets in the socket group 511, and can adapt to various types of external plugs 1. Optionally, a plurality of sockets 3 can be provided in the housing 2, so that the number of external plugs 1 that can be connected to the power strip at the same time is increased.

[0048] like Figure 8 As shown, in some possible implementation schemes, the socket 3 and the movable part 4 are slidably connected through one or more guide components 10, and the guide components include a guide rail 101 and a slider 102. Any one of the guide rail 101 and the slider 102 is arranged in the socket 3 and located on the mounting groove; the other of the guide rail 101 and the slider 102 is arranged on the outer wall of the movable part 4. The arrangement of the guide component 10 makes the movement of the movable part 4 more stable, thereby improving the service life of the movable part 4. Among them, one of the guide rail 101 or the slider 102 is integrally connected with the movable part 4, and the other is integrally connected with the socket 3, so that the arrangement of the guide rail 101 and the slider 102 becomes simple, and the production cost is reduced.

[0049] like Figure 8 and Fig.11 As shown, in some possible implementations, the movable member 4 is provided with a plug 11 (refer to Figure 3 ) is provided with two abutting portions 41, and the two abutting portions 41 are arranged at opposite ends of the spring sheet 31 with a relative spacing. The abutting portion 41 is arranged as a recess matching the plug pin 11, so that the plug pin 11 can be inserted into the abutting portion 41 to abut against the movable member 4. In this way, the connection between the plug pin 11 and the abutting portion 41 is stable, and misalignment is avoided when the plug pin 11 is inserted and abuts against the movable member 4.

[0050] The embodiment of the utility model provides a power strip, comprising a housing 2, a socket 3, a movable part 4, a lifting cover 5, a transmission part 6 and a locking mechanism 7. An opening 21 is provided on the housing 2, the housing 2 is movably arranged in the opening 21, the movable part 4 is arranged in the mounting groove of the lifting cover 5, and the movable part 4 and the lifting cover 5 are connected by the transmission part 6. In this way, when the pin 11 is inserted and drives the movable part 4 to fall back, the lifting cover 5 can be driven to rise. Moreover, by applying a driving force to the lifting cover 5 toward the housing 2, the lifting cover 5 can be made to fall back.

[0051] In addition, a spring sheet 31 is provided in the mounting groove. When the pin 11 is inserted to the maximum displacement, the spring sheet 31 clamps the pin 11, thereby limiting the lifting of the movable part 4. At the same time, the setting of the locking mechanism 7 also limits the movement of the movable part 4. Therefore, the locking mechanism 7 and the spring sheet 31 cooperate with each other to jointly limit the movement of the movable part 4. Therefore, even if the clamping force of the spring sheet 31 becomes smaller due to long-term use, the locking mechanism 7 can compensate for the reduced clamping force, thereby still limiting the lifting of the movable part 4, thereby preventing the lifting cover 5 from falling back. In this way, when the pin 11 is connected to the spring sheet 31, the embodiment of the utility model prevents the lifting cover 5 from falling back, and drives the movable part 4 to rise through the transmission member 6, thereby preventing the movable part 4 from driving the pin 11 to separate from the spring sheet 31, and preventing the spring sheet 31 from disconnecting the electrical connection with the pin 11.

[0052] like Figure 4-6 As shown, in some embodiments, the locking mechanism 7 includes an elastically retractable locking member 71, and a sliding channel 72 is provided on one of the movable member 4 and the socket 3, and an outlet is provided at one end of the sliding channel 72, and the other end is provided as a closed end to install the locking member 71. A first guide structure 8 is provided on the other, and the first guide structure 8 includes a first limiting portion 81. The locking member 71 is arranged in the sliding channel 72 and has a guiding state and a locking state. In the guiding state, the locking member 71 is slidably connected to the first guide structure 8. In the locking state, the pin 11 is connected to the spring 31, and the locking member 71 abuts against the first limiting portion 81, so that the first limiting portion 81 limits the movement of the locking member 71. Among them, the first limiting structure not only plays a limiting role, but also plays a guiding role. Through the above-mentioned arrangement, the first guide structure 8 plays a guiding role in the movement of the locking member 71, which can not only prevent the locking member 71 from getting stuck; but also improve the accuracy of the movement of the locking member 71, ensuring that the locking member 71 can move to connect with the first limiting portion 81 when the external plug 1 is inserted, and also ensuring that the locking member 71 can smoothly disengage from the first limiting portion 81 when the lifting cover 5 falls back.

[0053] The locking member 71 of the embodiment of the utility model is arranged in a flexible and diverse manner and can be selected as needed. Among them, the arrangement of the locking member 71 includes but is not limited to the following three implementations:

[0054] In a possible implementation, the locking member 71 is configured as an elastic telescopic rod, which is slidably connected in the sliding channel 72 and is configured in a compressed state in the sliding channel 72 to extend out of the sliding channel 72 and connect to the first guide structure 8. One end of the elastic telescopic rod extends out of the exit of the sliding channel 72 and abuts against the first guide structure 8; the other end of the elastic telescopic rod abuts against the inner wall of the sliding channel 72 at the closed end.

[0055] like Figure 4 and Figure 5As shown in a possible embodiment, the locking mechanism 7 includes an elastic driving member 711 and a sliding member 712, and the sliding member 712 is slidably connected in the sliding channel 72. The elastic driving member 711 is arranged in the sliding channel 72 and between the sliding member 712 and the closed end of the sliding channel 72, and is set to a compressed state to drive the sliding member 712 to extend out of the sliding channel 72 and connect with the first guide structure 8.

[0056] like Figure 4 and Figure 5 As shown, in a possible implementation manner, the locking mechanism 7 includes an elastic driving member 711 and a sliding member 712, and the sliding member 712 is slidably connected in the sliding channel 72. The elastic driving member 711 is arranged in the sliding channel 72, and is arranged between the sliding member 712 and one end of the sliding channel 72 located at the outlet, and is set in a stretched state to drive the sliding member 712 to extend out of the sliding channel 72 and connect with the first guide structure 8.

[0057] In some other embodiments, the locking mechanism 7 includes a first limiting structure and a second limiting structure, the first limiting structure is arranged on the outer side wall of the movable part 4, and the second limiting structure is arranged on the inner side wall of the socket 3. When the pin 11 is connected to the spring sheet 31, the first limiting structure is connected to the second limiting structure so that the second limiting structure limits the movement of the movable part 4. When the pin 11 is separated from the spring sheet 31 and the lifting cover 5 is subjected to a driving force, the first limiting structure and the second limiting structure are disconnected. Specifically, one of the first limiting structure and the second limiting structure is set as a protrusion, and the other is set as a groove. Through the above-mentioned arrangement, the structure of the locking mechanism 7 is simple, and the manufacturing cost of the locking mechanism 7 is reduced.

[0058] like Figure 4-6 As shown, in some embodiments, the first guide structure 8 further includes a first guide portion 82, and the first limiting portion 81 is tilted so that when the locking member 71 abuts against the first limiting portion 81, the friction force and the supporting force applied to the locking member 71 by the first limiting portion 81 can provide a component force along the insertion direction of the pin 11, thereby hindering the lifting of the movable member 4. In addition, the first limiting portion 81 has a simple structure and low manufacturing cost. The first guide portion 82 extends along the depth direction of the installation groove and is connected to the first limiting portion 81 to guide the locking member 71 to the first limiting portion 81. The setting of the first guide portion 82 avoids the locking member 71 from getting stuck when it slides toward the first limiting portion 81 or slides out of the first limiting portion 81.

[0059] like Figure 6 and Figure 7As shown, in some embodiments, a second guide structure 73 is provided on the locking member 71, and is connected to the first guide structure 8 through the second guide structure 73. In the guiding state, at least part of the second guide structure 73 is slidably connected to the first guide structure 8. In the locked state, at least the other part of the second guide structure 73 abuts against the first limit portion 81. Through the provision of the second guide structure 73, the connection between the first guide structure 8 and the locking member 71 is more stable, so that the locking member 71 will not deviate from the motion trajectory guided by the first guide structure 8 during the movement.

[0060] like Figure 4-7 As shown, in some possible implementations, either one of the first guide structure 8 and the second guide structure 73 is configured as a guide groove, and the other is configured as a guide protrusion. The configuration of the first guide structure 8 and the second guide structure 73 can be selected as needed in the embodiment of the utility model.

[0061] like Figure 4 and Figure 8 As shown, in some further embodiments, when the first guide structure 8 is set as a guide protrusion, the second guide structure 73 is set as a guide groove, and the sliding channel 72 is set on the movable part 4, a sliding groove 42 is set on the movable part 4 along the depth direction of the mounting groove. The depth of the sliding groove 42 is the same as the height of the first guide structure 8. The sliding groove 42 is slidably connected to the first guide structure 8 to avoid a gap between the movable part 4 and the inner wall of the socket 3, thereby improving the stability of the movement of the movable part 4 and improving the space utilization of the mounting groove.

[0062] In some other embodiments, the first guide structure 8 and the second guide structure can be set as a guide plane, so that the structure of the first guide structure 8 and the second guide structure 73 is simple, easy to manufacture, and the manufacturing cost is reduced.

[0063] like Figure 4-7As shown, in some embodiments, the second guide structure 73 includes a second guide portion 731 and a third guide portion 732, and the second guide portion 731 is tilted, and the tilt angle of the second guide portion 731 is the same as the tilt angle of the first limiting portion 81. In this way, the connection between the second guide portion 731 and the first limiting portion 81 is achieved by the surface-to-surface contact, so that the connection between the second guide structure 73 and the first guide structure 8 is more stable. And in the locked state, the second guide portion 731 is contacted with the first limiting portion 81, which improves the limiting effect of the first limiting portion 81. In addition, the third guide portion 732 is connected to the second guide portion 731. In the guiding state, the third guide portion 732 is slidably connected to the first guide portion 82, or at least part of the second guide portion 731 is slidably connected to the first limiting portion 81. In this way, the connection between the second guide structure 73 and the first limiting portion 81 or the first guide portion 82 is very stable, thereby improving the movement stability of the second guide structure 73 and the first guide structure 8.

[0064] like Figure 5 and Figure 6 As shown, in some embodiments, the first guide structure 8 further includes a second limiting portion 83, which is disposed on the first limiting portion 81. In the limiting state, the locking member 71 abuts against the second limiting portion 83 to limit the locking member 71 from extending from the sliding channel 72. In this way, the length of the locking member 71 extending from the sliding channel 72 is limited, thereby making the structure more compact. Specifically, in the limiting state, the third guide portion 732 fits with the second limiting portion 83, so that the connection between the second guide structure 73 and the first guide structure 8 is more stable.

[0065] like Figure 4 and Figure 6 As shown, optionally, the socket 3 is further provided with a receiving hole 32, and at least part of the first limiting portion 81 and the second limiting portion 83 are both located in the receiving hole 32, so that in the locked state, the second guide structure 73 is located in the receiving hole 32. When the second guide structure 73 moves to the first limiting structure, the socket 3 has a space for the second limiting structure to extend from the sliding channel 72.

[0066] like Figure 4 and Figure 8 As shown, in some embodiments, a limiting protrusion 74 is provided on one of the inner walls of the locking member 71 and the sliding channel 72, and a limiting groove 75 is provided on the other along the extension direction of the sliding channel 72, and the limiting protrusion 74 is located in the limiting groove 75. In this way, when the locking member 71 is installed, the locking member 71 can be positioned in the circumferential direction in the sliding channel 72 through the connection between the limiting groove 75 and the limiting protrusion 74. Therefore, when the movable member 4 is installed in the installation groove, the second guide structure 73 can be connected to the first guide structure 8 without adjustment.

[0067] like Figure 2 , Figure 3 and Fig.12 As shown, in some embodiments, the power strip further includes one or more resetting elastic members 9 for driving the lifting cover 5 to fall back, one end of the resetting elastic member 9 is connected to the lifting cover 5, and the other end is connected to the socket 3 or the housing 2. When the lifting cover 5 falls back to the maximum displacement, the resetting elastic member 9 is at the original length; when the lifting cover 5 is raised to the maximum displacement, the elongation of the resetting elastic member 9 is the maximum value. In this way, when the pin 11 is separated from the spring 31, the clamping force of the spring 31 clamping the pin 11 disappears, and the resetting elastic member 9 can overcome the obstruction of the locking mechanism 7 and drive the lifting cover 5 to fall back, thereby realizing the automatic fall of the lifting cover 5.

[0068] like Fig.10 and Fig.11 As shown, in some embodiments, the transmission member 6 is configured as a gear, and a rotating shaft 61 is disposed on the gear, and the rotating shaft 61 is rotatably connected to the socket 3 or the housing 2. A first rack 43 is disposed on the movable member 4, and a second rack 53 is disposed on the lifting cover 5, and the first rack 43 and the second rack 53 are connected through a gear. The first rack 43 and the second rack 53 are disposed at opposite intervals on both sides of the gear, and are both disposed along the direction in which the pin 11 is inserted. Through gear transmission, the transmission between the movable member 4 and the lifting cover 5 is stable, and the structure is compact, so that the accommodating cavity is fully utilized.

[0069] like Fig.12 As shown, in some embodiments, the transmission member 6 includes a rotating shaft 61, a first transmission part 62 and a second transmission part 63. The rotating shaft 61 is rotatably connected to the socket 3 or the housing 2. The first transmission part 62 and the second transmission part 63 are both connected to the rotating shaft 61 to form a lever. The first transmission part 62 and the second transmission part 63 are distributed on both sides of the rotating shaft 61 and are located on the same straight line. The movable member 4 abuts on the first transmission part 62, and the lifting cover 5 abuts on the second transmission part 63. It can be understood that the movable member 4 falls back, driving the first transmission part 62 to descend, thereby driving the second transmission part 63 to rise, thereby driving the lifting cover 5 to rise, until the pin 11 is connected to the spring 31, and the lifting cover 5 rises to the maximum displacement. When the lifting cover 5 falls back, the second transmission part 63 is driven to descend, thereby driving the first transmission part 62 to rise, thereby driving the movable member 4 to rise. Since the distance between the first transmission part 62 and the center line of the rotating shaft 61 and the distance between the second transmission part 63 and the center line of the rotating shaft 61 are constant, and the maximum displacement of the movable part 4 when falling back is constant, the maximum displacement of the lifting cover 5 is guaranteed to be constant, and the lifting cover 5 can abut against the socket every time it is lifted to the maximum displacement.

[0070] like Fig. 9 and Fig.11As shown, in some possible implementation schemes, a cover plate 33 is connected to the top of the socket 3, and the socket 3 and the cover plate 33 enclose the above-mentioned mounting groove. A mounting hole 34 is formed between the side wall of the cover plate 33 and the side wall of the socket 3, a part of the mounting hole 34 is arranged on the side wall of the cover plate 33, and the other part is arranged on the side wall of the socket 3, and the rotating shaft 61 is rotatably connected in the mounting hole 34. In this way, the assembly and disassembly of the rotating shaft 61 can be realized by installing and disassembling the cover plate 33, which facilitates the assembly and disassembly of the rotating shaft 61. Among them, the connection method between the cover plate 33 and the socket 3 includes but is not limited to bolt connection, plug-in connection, clamping connection and riveting connection, etc., and different connection methods can be selected as needed, which has good flexibility.

[0071] like Fig.11 As shown, in some possible implementation schemes, two transmission members 6 may be provided, and the two transmission members 6 are provided on two opposite sides of the socket 3, so that the force on the movable member 4 and the lifting cover 5 is uniform, thereby improving the service life of the movable member 4 and the lifting cover 5.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
