Description

Technical Field

[0001] The utility model relates to the field of track sockets, in particular to a socket adapter for a track socket. Background Art

[0002] The track socket includes an adapter and a long track. The track is installed on the wall, and the track socket in the track is electrically connected to the wall power line. The adapter has a conductive sheet and a socket. When using the track socket, the conductive sheet of the adapter is inserted into the track slot of the track and contacts the track socket in the track slot. Then, the plug of the electrical appliance is inserted into the socket of the adapter, and the electrical appliance can draw power from the adapter. The advantage of the track socket is that the adapter can be moved arbitrarily within a range by sliding the adapter in the track, so that the adapter can power electrical appliances in multiple locations.

[0003] The prior art can refer to a track socket adapter recorded in the Chinese utility model patent with the announcement number "CN218828298U", which includes a socket body, a guide body and a rotating member, wherein the rotating member includes a rotating cover located on the side of the socket body and rotatable around the axis of the socket body, the guide body passes through the side of the socket body away from the socket hole and is fixedly connected to the rotating cover, the ground wire is arranged in the guide body, and the end of the guide body away from the rotating cover is integrally connected to two side rods, the two side rods are symmetrically distributed about the axis of the guide body, the live wire is arranged in the side rod, and the live wire and the neutral wire are arranged separately. When this scheme is used, the rotating cover can drive the guide body and the side rod thereon to rotate, thereby controlling the on and off of the adapter. However, the rotary contact is difficult to ensure stable contact between the side rod and the conductor in the track, and it is easy to cause unstable power supply due to loose contact, so this scheme proposes a socket adapter with a new plug-in method. Summary of the invention

[0004] In order to solve the above problems, the purpose of the utility model is to provide a socket adapter. This solution adopts a longitudinal plug-in method of the terminal plug, which is different from the rotational contact method, and can ensure that the socket adapter can obtain power stably.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A socket adapter comprises a socket housing and a socket mechanism arranged inside the socket housing; a power panel exposed from the socket housing is arranged on the top of the socket mechanism, a neutral wire plug post, a live wire plug post and a ground wire plug post are arranged at the lower end of the socket mechanism, and the lower ends of the neutral wire plug post, the live wire plug post and the ground wire plug post can extend from the lower end surface of the socket housing; the socket mechanism is longitudinally movable and liftingly arranged inside the socket housing to adjust the length of the neutral wire plug post, the live wire plug post and the ground wire plug post extending from the socket housing.

[0007] The utility model adopts the above technical solution, which relates to a socket adapter, the socket mechanism of the socket adapter is longitudinally movable and arranged in the socket housing, the power panel at the upper end is used for plug power, and the neutral wire plug post, live wire plug post and ground wire plug post extending from the lower end are used to connect electricity from the track. Different from the prior art, after the neutral wire plug post, live wire plug post and ground wire plug post in this solution extend from the lower end surface of the socket housing, the socket mechanism can be raised and lowered, so that the extension length of the neutral wire plug post, live wire plug post and ground wire plug post can be adjusted, which can be used to control the on and off of the socket adapter. This solution adopts the method of longitudinal plug-in of the wiring plug post, which is different from the method of rotational contact, and can ensure the stability of power supply of the socket adapter.

[0008] The socket mechanism in the above scheme can be arranged in the socket housing with a push-rebound structure. The push-rebound structure can refer to the push-rebound power-on body recorded in the patent document with the announcement number "CN206180213U", or a similar structure thereof.

[0009] In a further embodiment, the socket housing includes a rotating cover and a guide plate at the center of the lower end of the rotating cover; the guide plate is provided with through holes for the neutral wire plug, the live wire plug and the ground wire plug to pass through; the upper end of the rotating cover is provided with a cover opening, the socket mechanism is embedded in the rotating cover and its power panel extends out of the rotating cover from the cover opening. This scheme constructs the socket housing into two parts: a rotating cover and a guide plate, wherein the through holes provided on the guide plate are used for the neutral wire plug, the live wire plug and the ground wire plug to pass through, so that the three connection plugs can extend out of the socket housing.

[0010] The rotating cover is rotatably arranged with the guide plate, and the inner wall of the rotating cover is connected with the socket mechanism in a threaded manner. When the rotating cover rotates, the socket mechanism is driven to rise and fall longitudinally. When an external force acts on the rotating cover to rotate it, the inner wall of the rotating cover is connected with the socket mechanism in a threaded manner, so that the socket mechanism is lifted and lowered longitudinally, and the extension length of the terminal plug relative to the socket housing is adjusted. The specific solution is that the inner wall of the rotating cover and the outer wall of the socket mechanism are respectively provided with a thread groove and a slider, and the slider is embedded in the thread groove to realize a threaded connection.

[0011] In a further solution, positioning structures are provided at both ends of the rotation path of the rotating cover and the guide plate, for positioning the rotating cover and the guide plate. In this solution, positioning structures are provided at both ends of the rotation path, so that the rotating cover can be positioned after being rotated to the switch position, thereby preventing it from being loosened during use, resulting in loosening when connected to the power supply.

[0012] In a specific solution, an upper ring body extending radially inward is constructed at the lower end of the rotating cover, a lower ring body is detachably connected to the lower end of the upper ring body, a gap is constructed between the upper ring body and the lower ring body, and the outer edge of the guide plate is at least partially embedded in the gap and can rotate circumferentially along the gap. Here, the outer edge of the guide plate is at least partially embedded in the gap between the upper ring body and the lower ring body, so that the guide plate and the rotating cover can rotate relative to each other without being separated from each other.

[0013] In a specific solution, a slide groove is constructed on the inner edge of the upper ring body and / or the lower ring body, and a positioning groove is separated at both ends of the slide groove by a block, and a positioning block extending into the interior of the slide groove is constructed on the outer edge of the guide plate; the positioning block is slidably arranged in the interior of the slide groove and can pass over the block and snap into the interior of the positioning groove. In this solution, the cooperation between the slide groove and the positioning block limits the rotation range of the rotating cover, and the positioning grooves separated by the block at both ends of the slide groove can cooperate with the positioning block to achieve positioning. In addition, when the user acts on the rotating cover, when the positioning block passes over the block and snaps into the interior of the positioning groove, an operation feedback will be given to the user, so that the user knows that it has been rotated into place.

[0014] Preferably, a safety door assembly is provided inside the socket mechanism, and the safety door assembly at least comprises a safety door movably provided below the power extraction panel.

[0015] Preferably, the lower end surface of the socket housing is provided with an insertion portion that can be inserted into the interior of the track, and the side wall of the insertion portion is provided with a block that can extend out of the side wall and clamp the track. In this solution, the insertion portion at the lower end of the socket housing can be inserted into the interior of the track, and the block on its side wall is extended to be fixed to the track to prevent the socket adapter from being detached from the track. In a specific implementation scheme, the block is slidably arranged inside the socket housing and supported on the output end of the elastic reset component, and the elastic reset component drives the block to return to the interior of the socket housing; the upper end of the block is constructed as a first inclined surface, and the lower end of the socket mechanism is constructed with a pressing block, and the lower end surface of the pressing block is set as a second inclined surface that matches the first inclined surface; when the socket mechanism drives the pressing block downward to act on the block, the block is driven to extend out of the socket housing. In this solution, when the socket mechanism is downward, the block is driven to extend out of the socket housing based on the abutment of the inclined surfaces, so that the socket adapter is locked with the track when it is powered on. When the socket mechanism moves upward, the force of the pressing block on the clamping block is released, and the clamping block rebounds into the socket housing under the action of the elastic reset component. At this time, the socket adapter can be removed from the track.

[0016] Preferably, a light is provided in the socket mechanism, and a light-transmitting panel is provided on the power panel for the light of the light-emitting lamp to emit. When the socket mechanism is connected to electricity, the user can observe the light from the light-transmitting panel of the power panel, thereby knowing that the current state is powered on.

[0030] like Figures 1 to 8 As shown, this embodiment relates to a socket adapter, including a socket housing 1, and a socket mechanism 2 arranged inside the socket housing 1. The top of the socket mechanism 2 is provided with a power panel 21 exposed from the socket housing 1, and the lower end of the socket mechanism 2 is provided with a neutral wire plug 22, a live wire plug 23 and a ground wire plug 24, and the lower ends of the neutral wire plug 22, the live wire plug 23 and the ground wire plug 24 can extend from the lower end surface of the socket housing 1. The socket mechanism 2 is longitudinally movable and lifted inside the socket housing 1 to adjust the length of the neutral wire plug 22, the live wire plug 23 and the ground wire plug 24 extending from the socket housing 1. The socket mechanism 2 of the socket adapter is longitudinally movable and arranged inside the socket housing 1, and the power panel 21 at the upper end is used for plug power, and the neutral wire plug 22, the live wire plug 23 and the ground wire plug 24 extending from the lower end are used to connect electricity from the track. Different from the prior art, after the neutral plug 22, the live plug 23 and the ground plug 24 in this solution extend from the lower end surface of the socket housing 1, the socket mechanism 2 can be raised and lowered, so that the extension length of the neutral plug 22, the live plug 23 and the ground plug 24 can be adjusted, which can be used to control the on and off of the socket adapter. This solution adopts the longitudinal plugging method of the wiring plug, which is different from the rotational contact method, and can ensure the stable power supply of the socket adapter.

[0031] In one feasible scheme, the socket mechanism 2 in the above scheme can be arranged in the socket housing 1 using a push-rebound structure. The push-rebound structure can be a push-rebound power-on body recorded in the patent document with reference to the announcement number "CN206180213U", or a similar structure thereof.

[0032] In such Figures 4 to 6 In the preferred embodiment shown, the socket housing 1 includes a rotating cover 11 and a guide plate 12 at the center of the lower end of the rotating cover 11. The guide plate 12 is provided with a through hole 120 for the neutral wire plug 22, the live wire plug 23 and the ground wire plug 24 to pass through. The upper end of the rotating cover 11 is provided with a cover opening 110, the socket mechanism 2 is embedded in the rotating cover 11 and its power panel 21 extends out of the rotating cover 11 from the cover opening 110. This scheme constructs the socket housing 1 into two parts: the rotating cover 11 and the guide plate 12, wherein the through hole 120 provided on the guide plate 12 is used for the neutral wire plug 22, the live wire plug 23 and the ground wire plug 24 to pass through, so that the three wiring plugs can extend out of the socket housing 1. The rotating cover 11 and the guide plate 12 are rotatably arranged, and the inner wall of the rotating cover 11 is threadedly connected to the socket mechanism 2. When the rotating cover 11 rotates, the socket mechanism 2 is driven to rise and fall longitudinally. When external force acts on the rotating cover 11 to make it rotate, the inner wall of the rotating cover 11 is connected to the socket mechanism 2 in a threaded manner, so that the socket mechanism 2 is lifted and lowered longitudinally, and the extension length of the terminal plug relative to the socket housing 1 is adjusted. The specific solution is that the inner wall of the rotating cover 11 and the outer wall of the socket mechanism 2 are respectively provided with a thread groove 19 and a slider 29, and the slider 29 is embedded in the thread groove 19 to realize a threaded connection.

[0033] like Figure 7 and 8 In the specific scheme shown, the lower end of the rotating cover 11 is constructed with an upper ring body 111 extending radially inward, and a lower ring body 13 is detachably connected below the upper ring body 111. A gap is constructed between the upper ring body 111 and the lower ring body 13, and the outer edge 121 of the guide plate 12 is at least partially embedded in the gap and can rotate circumferentially along the gap. Here, the outer edge 121 of the guide plate 12 is at least partially embedded in the gap between the upper ring body 111 and the lower ring body 13, so that the guide plate 12 and the rotating cover 11 can rotate relative to each other without being separated from each other.

[0034] In a further solution, positioning structures are provided at both ends of the rotation path of the rotating cover 11 and the guide plate 12, which are used to position the rotating cover 11 and the guide plate 12. This solution provides positioning structures at both ends of the rotation path, which can position the rotating cover 11 after rotating it to the switch position, thereby avoiding loosening during use, which causes loosening when connected to the power supply. In a specific solution, a slide groove 112 is constructed on the inner edge of the upper ring body 111 and / or the lower ring body 13, and a positioning groove 114 is separated at both ends of the slide groove 112 by a stopper 113, and a positioning block 122 is constructed on the outer edge 121 of the guide plate 12 that extends into the interior of the slide groove 112. The positioning block 122 is slidably arranged inside the slide groove 112 and can pass over the stopper 113 and be inserted into the interior of the positioning groove 114. In this solution, the cooperation between the slide groove 112 and the positioning block 122 limits the rotation range of the rotating cover 11, and the positioning grooves 114 separated by the stoppers 113 at both ends of the slide groove 112 can cooperate with the positioning blocks 122 to achieve positioning. In addition, when the user acts on the rotating cover 11, when the positioning block 122 passes over the stoppers 113 and is inserted into the positioning groove 114, an operation feedback is given to the user, so that the user knows that the rotation has been completed.

[0035] In a further solution, an insertion portion 14 capable of extending into the interior of the track is constructed on the lower end surface of the socket housing 1, and a block 15 capable of extending out of the side wall and clamping the track is constructed on the side wall of the insertion portion 14. In this solution, the insertion portion 14 at the lower end of the socket housing 1 can extend into the interior of the track, and the block 15 on its side wall extends out to be fixed to the track to prevent the socket adapter from detaching from the track. In a specific implementation scheme, the block 15 is slidably arranged inside the socket housing 1 and supported on the output end of the elastic reset component 16, and the elastic reset component 16 drives the block 15 to retreat into the socket housing 1. The upper end of the block 15 is constructed as a first inclined surface 151, and a pressing block 17 is constructed at the lower end of the socket mechanism 2, and the lower end surface of the pressing block 17 is set as a second inclined surface 171 that matches the first inclined surface 151. When the socket mechanism 2 drives the pressing block 17 to move downward to act on the block 15, the block 15 is driven to extend out of the socket housing 1. In this solution, when the socket mechanism 2 moves downward, the inclined surfaces abut against each other to drive the card block 15 to extend out of the socket housing 1, so that the socket adapter is locked with the track when it is powered on. When the socket mechanism 2 moves upward, the force of the pressing block 17 on the card block 15 is released, and the card block 15 rebounds into the socket housing 1 under the action of the elastic reset component 16, and the socket adapter can be removed from the track.

[0036] Finally, a safety door assembly is provided inside the socket mechanism 2, and the safety door assembly at least includes a safety door movably provided below the power panel 21; the safety door assembly is used to ensure the safety of power supply, and belongs to the prior art. A light-emitting lamp is also provided inside the socket mechanism 2, and a light-transmitting panel 28 for the light of the light-emitting lamp to emit is provided on the power panel 21. When the socket mechanism 2 is connected to electricity, the user can observe the light from the light-transmitting panel 28 of the power panel 21, so as to know that the current state is powered on.
