Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to an improved adapter structure and a track socket. Background Technology

[0002] Existing adapters and track sockets are described in Chinese Invention Patent CN111786185B, entitled "Adapter and Track Socket," published on November 2, 2021. This patent discloses an adapter and track socket. The adapter includes an adapter body and a control component. The adapter body includes a socket body, a guide body, and a movable conductive sheet. The guide body is located on the side of the socket body facing away from the insertion hole and is fixedly connected to the socket body. The movable conductive sheet is connected to the control component. The control component controls the unfolding and retraction of the movable conductive sheet relative to the guide body. Using the adapter provided in this application, when it is necessary to slide the adapter on the track, the control component can be operated to control the movable conductive sheet to retract relative to the guide body, separating the movable conductive sheet from the track conductive sheet, and then the adapter can be slid, thereby achieving non-electrified sliding of the adapter on the track.

[0003] The track is equipped with a connecting groove with a track conductive plate. When the adapter's moving conductive plate is opened, it extends into the connecting groove and abuts against the track conductive plate to achieve electrical connection. In order to ensure that the moving conductive plate can extend stably into the connecting groove, the height of the connecting groove is made relatively large, so that there is a large gap between the moving conductive plate and the connecting groove.

[0004] However, the adapter with the above structure still has the following shortcomings: (1) Since the connection between the plug of the electrical device and the adapter is relatively firm, when the user unplugs the plug of the electrical device, the adapter will move upward, causing the moving conductive piece of the adapter to collide with the upper end of the connection slot. During the movement of the adapter, the connection between the moving conductive piece of the adapter and the track conductive piece in the connection slot is unstable. The friction between the moving conductive piece of the adapter and the track conductive piece in the connection slot generates an instantaneous electric arc, which poses a certain safety hazard. After long-term use, this will damage the moving conductive piece and the track conductive piece, reducing the life of the moving conductive piece and the track conductive piece. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an improved adapter structure that adds a limiting blocking member to reduce adapter movement, which is beneficial to the electrical connection stability of the moving conductive component and improves the service life of the moving conductive component.

[0006] Another objective of this invention is to provide a track socket that includes the above-described improved adapter structure.

[0007] The purpose of this utility model is achieved as follows:

[0008] An improved adapter structure includes a socket body and a guide seat. The socket body is placed on the guide seat and has a plug assembly, a rotatable movable conductive component, and a rotating component. The plug assembly and the movable conductive component are electrically connected. The socket body also includes a rotatable limiting stop. When the rotating component rotates, it causes the limiting stop and the movable conductive component to unfold or retract relative to the guide seat. This improved adapter structure, by adding a limiting stop, allows the limiting stop to cooperate with a corresponding limiting structure on the power rail when the adapter is installed, thereby reducing or limiting adapter movement when the plug is removed. Specifically, it reduces or limits the movement of the movable conductive component, reducing the instantaneous electric arc generated by friction between the movable conductive component and the track conductive plate assembly of the power rail, which is beneficial for the electrical connection stability of the movable conductive component and improves its service life.

[0009] The objective of this utility model can also be achieved by the following technical measures:

[0010] Specifically, the moving conductive component is connected to the rotating component and the limiting blocking component respectively; so that while the rotating component drives the moving conductive component to rotate, it also drives the limiting blocking component to move through the moving conductive component. There is no need to set a separate transmission limiting blocking component on the rotating component. Its structure is simple and has a good implementation effect.

[0011] Specifically, the moving conductive component includes an L-pole conductive rod, an N-pole conductive rod, a first gear fixed on the L-pole conductive rod, and a second gear disposed on the N-pole conductive rod. The limiting and blocking component includes a blocking rod and a third gear disposed on the blocking rod. The rotating component is sleeved on the outer periphery of the socket body, and the rotating component has teeth corresponding to the positions of the first and second gears, respectively. The first and third gears mesh. The lower ends of the L-pole conductive rod, the N-pole conductive rod, and the blocking rod all extend downwards out of the socket body to facilitate the extension of the lower ends of the L-pole conductive rod, the N-pole conductive rod, and the blocking rod to the guide seat. Furthermore, the meshing transmission between the teeth and the gears, as well as the meshing transmission between the gears, has a simple structure and good transmission effect.

[0012] Specifically, the lower end of the blocking rod is provided with a blocking head, and both sides of the blocking head extend out of the outer periphery of the blocking rod. The guide seat is provided with a mounting recess and a first receiving recess. The lower end of the blocking rod passes downward through the mounting recess and extends into the first receiving recess, and the third gear extends into the mounting recess. The mounting recess provides a stable working space for the third gear, and the first receiving recess provides a stable working space for the lower end of the blocking rod, which is conducive to the stable operation of the third gear and the blocking rod. Furthermore, both sides of the blocking head extending out of the outer periphery of the blocking rod can cooperate with the electric rail to form a limiting block for the adapter, and its limiting block effect is good.

[0013] Specifically, an elastic reset component and an elastic locking mechanism are provided between the socket body and the rotating component. When the rotating component drives the limiting blocking component and the moving conductive component to unfold relative to the guide seat, the elastic reset component is in a stretched state and the elastic locking mechanism is in a locked state. The elastic locking mechanism can realize the relative locking and relative unlocking between the socket body and the rotating component. When the rotating component is reset, the elastic reset component can provide a reset force for the rotating component, which facilitates the rotation and reset of the rotating component.

[0014] Specifically, the elastic locking mechanism includes an elastic stop, a locking member, and an elastic unlocking member. The elastic stop is elastically fixed to the socket body, the elastic unlocking member is elastically mounted on the rotating member, and the locking member is fixed to the rotating member and located on one side of the elastic unlocking member. When the rotating member drives the limiting stop and the moving conductive component to unfold relative to the guide seat, the locking member abuts against the elastic stop and the elastic unlocking member is close to the elastic stop. When unlocking, simply press the elastic unlocking member, which pushes the elastic stop to rotate, causing the elastic stop to disengage from the locking member. At this time, the rotating member can rotate and reset under the reset force of the elastic reset member, making the operation simple and convenient.

[0015] Specifically, the elastic stop includes a stop block and a first spring. One end of the stop block is rotatably mounted on the socket body, and both ends of the first spring abut against the other end of the stop block and the socket body, respectively, so as to realize the elastic movement of the stop block on the socket body. Its structure is simple and can achieve a good elastic blocking effect.

[0016] Specifically, the elastic unlocking component includes an unlocking key and a second spring. The unlocking key is engaged with the rotating component, and the two ends of the second spring abut against the unlocking key and the rotating component, respectively. One end of the unlocking key extends into the inner side of the rotating component, and a locking block is provided on the inner side of the rotating component near the end of the unlocking key. The locking block constitutes the locking component. When the rotating component drives the limiting blocking component and the moving conductive component to unfold relative to the guide seat, the locking block abuts against the other end of the block, so that the rotating component is locked by the block, keeping the rotating component, the limiting blocking component and the moving conductive component stably in the unfolded state.

[0017] Another objective of this utility model is achieved as follows:

[0018] A track socket including the aforementioned improved adapter structure is characterized by further including an electric track, on which a groove is provided for sliding of the lower part of the guide seat. The electric track has a conductive space and a limiting space communicating with the groove. A track conductive sheet assembly is disposed within the conductive space. When the rotating component rotates, causing the limiting stop and the moving conductive assembly to unfold relative to the guide seat, the moving conductive assembly extends into the conductive space and abuts against the track conductive sheet assembly, and the limiting stop extends into the limiting space. This track socket, through the cooperation of the limiting stop and the limiting space, reduces or limits the adapter movement caused when the plug is unplugged, that is, reduces or limits the movement of the moving conductive assembly, reduces the instantaneous arc between the moving conductive assembly and the track conductive sheet assembly, and ensures the service life of the moving conductive assembly and the track conductive sheet assembly.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) This adapter has an improved structure. By adding a limiting stop, the limiting stop can cooperate with the corresponding limiting structure on the power rail when the adapter is installed on the power rail, so as to reduce or limit the movement of the adapter when the plug is pulled out. That is, to reduce or limit the movement of the moving conductive component, reduce the instantaneous arc generated by friction between the moving conductive component and the track conductive plate component of the power rail, which is beneficial to the electrical connection stability of the moving conductive component and improve the service life of the moving conductive component.

[0021] (2) The recess provides a stable working space for the third gear component and the first receiving recess provides a stable working space for the lower end of the blocking rod, which is conducive to the stable operation of the third gear component and the blocking rod. Furthermore, the two sides of the blocking head extending out of the outer periphery of the blocking rod can cooperate with the electric rail to form a limiting block for the adapter, and its limiting block effect is good.

[0022] (3) When the rotating part drives the limiting blocking part and the moving conductive component to unfold relative to the guide seat, the locking part and the elastic blocking part abut against each other and the elastic unlocking part is close to the elastic blocking part; when unlocking, just press the elastic unlocking part, the elastic unlocking part pushes the elastic blocking part to rotate, so that the elastic blocking part is separated from the locking part. At this time, the rotating part can rotate and reset under the reset force of the elastic reset part, which is simple and convenient to operate. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Implementation examples, in conjunction with Figures 1 to 6 As shown, an improved adapter structure includes a socket body 1 and a guide seat 2. The socket body 1 is placed on the guide seat 2. The socket body 1 is provided with a plug assembly 3, a rotatable movable conductive component 4, and a rotating component 5. The plug assembly 3 and the movable conductive component 4 are electrically connected. The socket body 1 is further provided with a rotatable limiting stop 6. When the rotating component 5 rotates, it causes the limiting stop 6 and the movable conductive component 4 to unfold or retract relative to the guide seat 2.

[0032] As a specific embodiment, the moving conductive component 4 is connected to the rotating component 5 and the limiting blocking component 6 respectively.

[0033] As a more specific embodiment, the moving conductive component 4 includes an L-pole conductive rod 41, an N-pole conductive rod 42, a first gear component 43 fixed on the L-pole conductive rod 41, and a second gear component 44 disposed on the N-pole conductive rod 42.

[0034] In this embodiment, the lower end of the blocking rod 61 is provided with a blocking head 63, and the two sides of the blocking head 63 extend out of the outer periphery of the blocking rod 61 respectively. The guide seat 2 is provided with a placement recess 21 and a first receiving recess 22. The lower end of the blocking rod 61 passes downward through the placement recess 21 and extends into the first receiving recess 22, and the third gear 62 extends into the placement recess 21.

[0035] In this embodiment, the guide seat 2 is provided with a communicating inner recess 23 and a second receiving recess 24. The lower part of the first gear component 43 extends downward with a lower protrusion 431. The lower end of the L-pole conductive rod 41 passes downward through the inner recess 23 and extends into the second receiving recess 24, and the lower protrusion 431 extends into the inner recess 23. There are two inner recesses 23 and two receiving recesses 24, so as to realize the receiving and fixing of the L-pole conductive rod 41 and the N-pole conductive rod 42 on the guide seat 2.

[0036] In this embodiment, the lower part of the socket body 1 is also provided with an E-pole conductive rod 11 that is electrically connected to the plug assembly 3, and the guide seat 2 has a through hole 25, through which the lower end of the E-pole conductive rod 11 passes downward through the through hole 25.

[0037] As a preferred embodiment, an elastic reset member 7 and an elastic locking mechanism 8 are provided between the socket body 1 and the rotating member 5. When the rotating member 5 drives the limiting blocking member 6 and the moving conductive component 4 to unfold relative to the guide seat 2, the elastic reset member 7 is in a stretched state and the elastic locking mechanism 8 is in a locked state.

[0038] In this embodiment, the elastic locking mechanism 8 includes an elastic stop 81, a locking member 82, and an elastic unlocking member 83. The elastic stop 81 is fixed to the socket body 1 in an elastically movable manner, the elastic unlocking member 83 is disposed on the rotating member 5 in an elastically movable manner, and the locking member 82 is fixed on the rotating member 5 and is located on one side of the elastic unlocking member 83.

[0039] In this embodiment, the elastic stop 81 includes a stop block 811 and a first spring 812. One end of the stop block 811 is rotatably mounted on the socket body 1, and the two ends of the first spring 812 abut against the other end of the stop block 811 and the socket body 1, respectively.

[0040] In this embodiment, the elastic unlocking member 83 includes an unlocking key 831 and a second spring 832. The unlocking key 831 is engaged with the rotating member 5, and the two ends of the second spring 832 abut against the unlocking key 831 and the rotating member 5 respectively. One end of the unlocking key 831 extends into the inner side of the rotating member 5, and a locking block is provided on the inner side of the rotating member 5 near the end of the unlocking key 831. The locking block constitutes the locking member 82.

[0041] As a more specific embodiment, the rotating component 5 includes a rotating upper shell 52 and a rotating lower shell 53 connected to each other. The rotating upper shell 52 is provided with the unlocking button 831 and the second spring 832. The rotating lower shell 53 is sleeved on the outer periphery of the socket body 1 and has a toothed portion 51 on the inner side of its bottom.

[0042] When it is necessary to unfold the limiting stop 6 and the moving conductive component 4, the rotating component 5 is rotated, and through the toothed part 51 meshing with the first gear 43, the toothed part 51 meshing with the second gear 44, and the first gear 43 meshing with the third gear 62, the limiting stop 6 and the moving conductive component 4 are driven to rotate and unfold relative to each other until the locking part 82 on the rotating component 5 abuts against the elastic stop 81 and the elastic unlocking part 83 is close to the elastic stop 81. At this time, the rotating component 5 is in a locked state. To unlock the rotating component 5, simply press the elastic unlocking part 83. The elastic unlocking part 83 pushes the elastic stop 81 to rotate, so that the elastic stop 81 is disengaged from the locking part 82. At this time, the rotating component 5 can rotate and reset under the reset force of the elastic reset part 7. The operation is simple and convenient.

[0043] Combination Figure 7 As shown, a track socket including the above-mentioned improved adapter structure also includes an electric track 9. The electric track 9 is provided with a groove 91 for sliding the lower part of the guide seat 2. The electric track 9 has a conductive space 92 and a limiting space 93 communicating with the groove 91. The conductive space 92 is provided with a track conductive sheet assembly 94. When the rotating member 5 rotates and drives the limiting blocking member 6 and the moving conductive assembly 4 to unfold relative to the guide seat 2, the moving conductive assembly 4 extends into the conductive space 92 and abuts against the track conductive sheet assembly 94, and the limiting blocking member 6 extends into the limiting space 93.

[0044] As a more specific solution, silicone baffles 10 are respectively installed at both ends of the electric track 9 located on the upper part of the slide 91. The corresponding ends of the two silicone baffles 10 abut against each other, and the two silicone baffles 10 seal the upper opening of the slide 91.

[0045] As a more specific solution, the gap between the limiting stop 6 and the limiting space 93 is smaller than the gap between the moving conductive component 4 and the conductive space 92. With a smaller gap between the limiting stop 6 and the limiting space 93, when the adapter moves, the limiting stop 6 will abut against the upper surface of the limiting space 93, so that the adapter will no longer move. This ensures that the moving conductive component 4 will not rub against the track conductive sheet assembly 94 and will not abut against the upper surface of the conductive space 92, which is beneficial to improving the service life of the moving conductive component 4.
