Description

Technical Field

[0001] This utility model relates to the field of power socket structure design, and more specifically to a track socket. Background Technology

[0002] A power strip typically includes a power rail and an adapter, which can be mounted on the power rail to draw power from different locations. For example, Chinese Utility Model Patent CN218005476U discloses an adapter for a power strip, comprising an adapter body with a neutral terminal electrically connected to a neutral wire socket and a live terminal electrically connected to a live wire socket; a positioning frame fixed to the bottom of the adapter body, on which two vertical terminals are rotatably mounted, one for the live wire and one for the neutral wire, respectively electrically connected to the live and neutral terminals, and each terminal has a horizontal pin at its bottom; and a rotating ring rotatably mounted on the adapter body, connected to the two terminals via a linkage mechanism, so that when the rotating ring rotates, the linkage mechanism drives the two terminals to rotate relative to the positioning frame; the linkage mechanism includes two transmission gears respectively mounted on the two terminals and two arc-shaped racks synchronously connected to the rotating ring, with the two transmission gears meshing with the two arc-shaped racks.

[0003] The applicant's repeated investigations revealed a poor user experience with the rotation operation of the aforementioned adapter. Uneven rotational resistance and an unreasonable design gap in the rotating coil resulted in inconsistent rotational resistance or jamming, making operation difficult for the user. The limiting structure lacked strength; the angle limiting relied on the mechanical resistance of the first and second stops. If the stop material was not strong enough, prolonged impact could easily cause deformation or breakage, leading to over-travel and damage to the internal mechanism. Furthermore, the complex structure, numerous components, relatively cumbersome assembly, and high manufacturing costs further exacerbated the problem. Utility Model Content

[0004] In order to overcome the technical defects of the existing track socket adapter technology, such as poor rotation operation experience and uneven rotation resistance causing users to have difficulty operating, this utility model provides a track socket.

[0005] To solve the above problems, this utility model is implemented according to the following technical solution:

[0006] The present invention discloses a track socket, comprising a guide rail assembly and a sliding socket assembly. The guide rail assembly has a first slide rail and a second slide rail. A first conductive sheet is axially embedded in the first slide rail, and a second conductive sheet is axially embedded in the second slide rail. The sliding socket assembly includes a transmission mechanism, a linkage mechanism, and a plug-in module. The transmission mechanism has a gear and an arc-shaped through hole. The linkage mechanism includes a first linkage component and a second linkage component that mesh with the gear. The plug-in module is axially connected to the transmission mechanism through a conductive post. The transmission mechanism drives the linkage mechanism to move radially along the arc-shaped through hole through rotational motion, thereby realizing the connection or disconnection switching between the plug-in module and the first and second conductive sheets.

[0007] Preferably, the first linkage component includes a first claw-shaped tooth and a first L-shaped conductive arm, the first claw-shaped tooth meshing with the gear; the vertical section of the first L-shaped conductive arm passes through the first claw-shaped tooth and is connected to the plug-in module, and the horizontal section of the first L-shaped conductive arm is provided with a first clamping part at its end; the first clamping part is connected to the first conductive sheet.

[0008] Preferably, the second linkage component includes a second claw-shaped tooth and a second L-shaped conductive arm, the second claw-shaped tooth meshing with the gear; the vertical section of the second L-shaped conductive arm passes through the second claw-shaped tooth and is connected to the plug-in module, and the horizontal section of the second L-shaped conductive arm is provided with a second clamping part at its end; the second clamping part is connected to the second conductive sheet.

[0009] Preferably, the sliding socket assembly further includes a housing and a base. The housing has an inner cavity with a mounting groove that engages with a mounting hole on the outer edge of the transmission mechanism for fixation. The base is connected to the housing and is used for sliding engagement of the sliding socket assembly on the guide rail assembly.

[0010] Preferably, the base includes a substrate and a guide bracket, wherein a first guide hole and a second guide hole are formed on the substrate; the guide bracket is vertically disposed on the surface of the substrate; and the guide bracket includes a first L-shaped through hole and a second L-shaped through hole that rotatably engage with the first L-shaped conductive arm and the second L-shaped conductive arm.

[0011] Preferably, the guide rail assembly is provided with a sliding groove, which is adapted to the guide bracket.

[0012] Preferably, the plug-in module includes an insulating base, a first conductive terminal, and a second conductive terminal. The insulating base is plugged into the conductive post. One end of the first conductive terminal is disposed on the insulating base, and the other end of the first conductive terminal is embedded in the U-shaped groove of the transmission mechanism and electrically connected to the vertical segment of the first L-shaped conductive arm. One end of the second conductive terminal is disposed on the insulating base, and the other end of the second conductive terminal is embedded in the U-shaped groove and electrically connected to the vertical segment of the second L-shaped conductive arm. The surface of the insulating base is provided with a standard socket group, which includes a national standard three-hole socket and / or a USB charging module.

[0013] Preferably, the housing surface is provided with a recessed hole, which is adapted to the standard socket assembly.

[0014] Preferably, a spring is provided between the plug-in module and the transmission mechanism, and the spring is used to maintain the initial position of the plug-in module in the power-off state.

[0015] Preferably, the arc-shaped through hole forms a rotation angle limiting fit with the first linkage component and the second linkage component respectively; the central angle of the arc-shaped through hole is in the range of 0°-93°, corresponding to the on / off stroke of the first linkage component and the second linkage component.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The track socket provided by this utility model significantly improves the user experience of rotating the socket within the guide rail assembly through the meshing transmission mechanism and the linkage mechanism, as well as the sliding guide design of the linkage mechanism within the arc-shaped through hole. This effectively eliminates the feeling of jamming and uneven resistance during rotation, allowing users to rotate the socket to the desired position more easily, smoothly, and effortlessly. When the user rotates the drive gear through the transmission mechanism, its rotational motion is transmitted to the linkage mechanism through the meshing structure. The cooperation between the gear and the linkage mechanism amplifies the force applied by the user using mechanical principles, making it easy to rotate the socket. It can transmit the rotational force applied by the user evenly and continuously to the linkage mechanism, avoiding sudden changes in local resistance or jamming. The arc-shaped through hole guide ensures smoothness and uniform resistance, with the first and second linkage components of the linkage mechanism slidingly engaged within this arc-shaped through hole. The arc-shaped through hole provides a precise rotational trajectory and constraint for the first and second linkage components. Because the motion trajectory is precisely defined as an arc and the sliding surface is continuous and smooth, the frictional resistance changes very little throughout the entire rotation stroke. The rotational resistance felt by the user is very uniform, eliminating the unpleasant experience of "sometimes tight, sometimes loose." The user only needs to slightly twist the transmission mechanism control gear, and the rotational force is smoothly amplified through the meshing of the gear and the linkage mechanism. The first and second linkage components slide smoothly along the preset arc-shaped through hole. This arc-shaped through hole precisely guides the entire driven device, along with the driving device and the socket body, to rotate along the desired circular path. Due to the force-saving effect of the meshing transmission, the precise constraint of the motion trajectory by the arc-shaped through hole, and the smoothness and consistency of the sliding friction surface, the entire rotation process has low resistance, uniform resistance, and no jamming, thus achieving the significant beneficial effects of effortless operation and a smooth, fluid feel.

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] like Figures 1-9As shown, the present invention provides a track socket comprising a guide rail assembly 1 and a sliding socket assembly 2. The guide rail assembly 1 is provided with a first slide rail 11 and a second slide rail 12. A first conductive sheet 111 is axially embedded in the first slide rail 11, and a second conductive sheet 121 is axially embedded in the second slide rail 12. The sliding socket assembly 2 includes a transmission mechanism 21, a linkage mechanism 22, and a plug-in module 23. The transmission mechanism 21 is provided with a gear 211 and an arc-shaped through hole 212. The linkage mechanism 22 includes a first linkage component 221 and a second linkage component 222 that mesh with the gear 211. The plug-in module 23 is axially connected to the transmission mechanism 21 via a conductive post 231. The transmission mechanism 21 drives the linkage mechanism 22 to move radially along the arc-shaped through hole 212 through rotational motion, thereby realizing the connection or disconnection switching of the plug-in module 23 with the first conductive sheet 111 and the second conductive sheet 121.

[0037] Understandably, the guide rail assembly 1 of this application has a first slide rail 11 and a second slide rail 12 arranged in parallel inside, and a first conductive plate 111 and a second conductive plate 121 are axially embedded and fixed in the slide rails respectively, forming a stable power supply track. The sliding socket assembly 2 integrates a high-efficiency power transmission and electrical connection structure, including a transmission mechanism 21, a linkage mechanism 22, and a plug-in module 23. Among them, the transmission mechanism 21 has a gear 211 and an arc-shaped through hole 212 that cooperates with the rotation trajectory of the gear 211; the linkage mechanism 22 includes a first linkage component 221 and a second linkage component 222, which directly mesh with the gear 211 of the transmission mechanism 21; the plug-in module 23 is axially fixedly connected to the transmission mechanism 21 through a conductive post 231. Its significant effect is reflected in the operation process: when the user rotates the transmission mechanism 21, the rotation of the gear 211 precisely drives the meshing first linkage component 221 and second linkage component 222, forcing them to move radially (i.e., perpendicular to the axial direction of the conductive post 231) along the preset arc-shaped through hole 212 trajectory. This radial movement causes the first linkage component 221 and the second linkage component 222 to contact the plug-in module 23 that is axially connected to them, thereby achieving a stable and reliable electrical connection or safe disconnection between the electrical contact point on the plug-in module 23 and the first conductive plate 111 and the second conductive plate 121 embedded in the guide rail assembly 1, completing a smooth switching of the power on / off state. This design ensures the stability of the contact and the smoothness of the operation.

[0038] In a preferred embodiment, such as Figures 3-7As shown, the first linkage component 221 includes: a first claw-shaped tooth 2211, which meshes with the gear 211; a first L-shaped conductive arm 2212, the vertical segment 2214 of which passes through the first claw-shaped tooth 2211 and is connected to the plug-in module 23, and the horizontal segment 2215 of the first L-shaped conductive arm 2212 is provided with a first clamping part 2213 at its end; the first clamping part 2213 is connected to the first conductive sheet 111.

[0039] The second linkage component 222 includes: a second claw tooth 2221, which meshes with the gear 211; a second L-shaped conductive arm 2222, the vertical segment 2214 of which passes through the second claw tooth 2221 and is connected to the plug-in module 23, and the horizontal segment 2215 of the second L-shaped conductive arm 2222 is provided with a second clamping part 2223 at its end; the second clamping part 2223 is connected to the second conductive sheet 121.

[0040] Understandably, such as Figure 6 As shown, the first linkage component 221 is a key component for achieving precise transmission and reliable conductivity. It includes a first claw-shaped tooth 2211 and a first L-shaped conductive arm 2212. The operational effect and advantages of the first linkage component 221 are reflected in the fact that the first claw-shaped tooth 2211 directly meshes with the gear 211 of the transmission mechanism 21, accurately converting the rotational motion of the gear 211 into its own rotation. The rotation of the vertical section 2214 drives the movement of the horizontal section 2215. The unique design of the L-shaped structure cleverly converts the rotational motion into the required radial (perpendicular to the axial direction of the conductive post 231) linear displacement: its vertical section 2214 passes through the first claw-shaped tooth 2211 and connects to the plug-in module 23, responsible for transmitting motion and positioning; while its horizontal section 2215, during the linkage process, drives the first clamping part 2213 at the end to move radially in a stable manner, realizing the clamping connection or separation with the first conductive sheet 111. Similarly, the movement and conduction mode of the second linkage component 222 can be obtained. This design ensures that under the drive of the gear 211, the first linkage component 221 and the second linkage component 222 can not only transmit motion efficiently and reliably, but also make a stable electrical connection with the connecting plug module 23. The first L-shaped conductive arm 2212, the second L-shaped conductive arm 2222, the first clamping part 2213, and the second clamping part 2223 built into the first linkage component 221 and the second linkage component 222 more directly and firmly establish the electrical path between the sliding socket component 2 and the first conductive piece 111 and the second conductive piece 121 of the guide rail component 1, realizing the integrated and efficient operation of mechanical linkage and electrical connection.

[0041] In a preferred embodiment, the sliding socket assembly 2 further includes: a housing 24, the inner cavity of which is provided with a mounting groove 241, the mounting groove 241 being fixed in conjunction with a mounting hole 214 on the outer edge of the transmission mechanism 21; and a base 25, which is connected to the housing 24 and is used for sliding engagement of the sliding socket assembly 2 on the guide rail assembly 1.

[0042] The base 25 includes: a base plate 251, on which a first guide hole 2511 and a second guide hole 2512 are formed; and a guide bracket 252, which is vertically disposed on the surface of the base plate 251. The guide bracket 252 includes a first L-shaped through hole 2521 and a second L-shaped through hole 2522 that rotatably engage with the first L-shaped conductive arm 2212 and the second L-shaped conductive arm 2222. The guide rail assembly 1 is provided with a sliding groove 13, which is adapted to the guide bracket 252.

[0043] Understandably, such as Figure 2 and Figure 8 As shown, the organic combination of the housing 24 and the base 25 improves the structural integrity and operational stability of the sliding socket assembly 2. The housing 24 has an internal mounting groove 241, which precisely engages with the mounting hole 214 on the outer edge of the transmission mechanism 21 via a pin. This engagement method directly achieves two effects: firstly, it firmly fixes the transmission mechanism 21 within the cavity of the housing 24, preventing displacement or shaking during operation; secondly, it provides a precise positioning reference for key transmission components such as the gear 211, ensuring the stability of its rotational movement and the reliability of its engagement with the linkage mechanism 22. The base 25 is tightly connected to the lower part of the housing 24, forming the base of the sliding socket assembly 2. Its core effect is that the lower surface of the base 25 vertically extends a guide bracket 252 to form a low-friction, smooth sliding engagement with the sliding groove 13 of the guide rail assembly 1. This not only enables the entire sliding socket assembly 2 to move freely and smoothly on the power supply track, allowing it to be flexibly positioned at any location required by the user, but also supports the weight of the housing 24 and the internal transmission mechanism 21, linkage mechanism 22 and plug-in module 23, ensuring the structural stability of the entire assembly during movement and use.

[0044] like Figures 4-5As shown, the precision guide design of the base 25 is crucial for ensuring the smooth operation of the sliding socket assembly 2 on the track and the precise movement of its internal mechanisms. The base 25 includes a base plate 251 and a guide bracket 252 vertically mounted on the base plate 251. The first guide hole 2511 and the second guide hole 2512 on the base plate 251 directly engage with the pre-set sliding groove 13 on the guide rail assembly 1. This hole-groove fit strictly limits the degree of freedom of movement of the base 25 and even the entire sliding socket assembly 2 relative to the guide rail assembly 1, ensuring that it can only slide smoothly and without offset along the axial direction of the guide rail, providing a stable foundation for arbitrary positioning of the socket on the track.

[0045] The vertically arranged guide bracket 252 has a first L-shaped through hole 2521 and a second L-shaped through hole 2522 that respectively form a rotational engagement with the vertical segments 2214 of the first L-shaped conductive arm 2212 and the second L-shaped conductive arm 2222. This engagement precisely limits the first L-shaped conductive arm 2212 and the second L-shaped conductive arm 2222 to only the radial movement and necessary rotation required by the design during the switching process, effectively preventing shaking or jamming during movement, ensuring the reliability and consistency of the linkage mechanism 22's operation, and thus ensuring the accuracy and stability of the electrical contact between the first clamping part 2213 and the second clamping part 2223 and the first conductive plate 111 and the second conductive plate 121.

[0046] Furthermore, the base 25, through the cooperation of the base plate 251 and the guide rail sliding channel 13, realizes the precise positioning and smooth movement of the component on the track; at the same time, through the guide bracket 252 and its first L-shaped through hole 2521 and second L-shaped through hole 2522 respectively constraining the rotation of the first L-shaped conductive arm 2212 and the second L-shaped conductive arm 2222, it provides reliable mechanical guidance for the precise radial movement of the internal linkage mechanism 22, and together ensures the smoothness, stability and efficiency of the overall function (movement, positioning, on / off) of the sliding socket.

[0047] In a preferred embodiment, the plug-in module 23 includes: an insulating base 232, which is plugged into the conductive post 231; a first conductive terminal 233, one end of which is disposed on the insulating base 232, and the other end of which is embedded in the U-shaped groove 213 of the transmission mechanism 21 and electrically connected to the vertical segment 2214 of the first L-shaped conductive arm 2212; a second conductive terminal 234, one end of which is disposed on the insulating base 232, and the other end of which is embedded in the U-shaped groove 213 and electrically connected to the vertical segment 2214 of the second L-shaped conductive arm 2222; the surface of the insulating base 232 is provided with a standard socket group, which includes a national standard three-hole socket and / or a USB charging module.

[0048] Understandably, the plug-in module 23, serving as the user interface and final power output unit of the sliding socket assembly 2, is designed with a high degree of integration between safe isolation and reliable power transmission. This module uses the insulating base 232 as its core carrier, directly plugging into and fixing itself to the conductive post 231 through the central hole 2321, ensuring a stable axial mechanical connection and precise positioning with the transmission mechanism 21. The first conductive terminal 233 and the second conductive terminal 234 are firmly fixed to the insulating base 232, while the other end is cleverly embedded in the U-shaped groove 213 of the transmission mechanism 21. This embedded connection method is crucial, as it allows the first conductive terminal 233 to form a tight electrical connection with the vertical segment 2214 of the first L-shaped conductive arm 2212, while the second conductive terminal 234 also establishes a stable electrical path with the vertical segment 2214 of the second L-shaped conductive arm 2222. The power (corresponding to the live wire and neutral wire) transmitted from the first L-shaped conductive arm 2212 and the second L-shaped conductive arm 2222 in the linkage mechanism 22 is safely, efficiently, and with low loss transmitted to the output terminal of the plug-in module 23. The conductive post 231 is connected to the third conductive terminal 2311, and the first conductive terminal 233 and the second conductive terminal 234 integrate a standard socket group, which includes power sockets conforming to national standards (such as three-hole sockets) and / or convenient USB charging modules. The final effect is reflected at the user end, where the user can directly insert the appliance plug or USB cable into the standard socket group. The insulating base 232 plays a key safety isolation role here, ensuring that the user contact point is completely isolated from the internal live parts (conductive terminals, conductive arms, conductive plates). At the same time, the power introduced through the first conductive terminal 233 and the second conductive terminal 234 is safely and stably delivered to the connected electrical equipment, realizing plug and play.

[0049] In a preferred embodiment, the surface of the housing 24 is provided with a recessed hole 242, which is adapted to the standard socket group. A spring 235 is provided between the plug-in module 23 and the transmission mechanism 21, and the spring 235 is used to maintain the initial position of the plug-in module 23 in the power-off state. The arc-shaped through hole 212 forms a rotation angle limiting engagement with the first linkage component 221 and the second linkage component 222 respectively; the central angle of the arc-shaped through hole 212 is in the range of 0°-93°, corresponding to the on / off stroke of the first linkage component 221 and the second linkage component 222.

[0050] To ensure the complete functionality and user safety of the sliding socket assembly 2, the key design details of the housing 24 and internal mechanisms provide multiple safeguards. The precisely cut socket clearance holes 242 on the surface of the housing 24 are perfectly matched in size and position to the standard socket group on the insulating base 232 of the plug-in module 23. Without compromising the structural strength of the housing 24 or the internal mechanisms, this provides users with an unobstructed plugging and unplugging channel, allowing electrical plugs or USB cables to be smoothly and accurately inserted into the socket group for power access, thus improving ease of use.

[0051] A spring 235 is specially provided between the plug-in module 23 and the transmission mechanism 21. The spring 235 can realize automatic reset when the power is cut off. When the user operates the plug to disengage from the sliding socket, and the power is disconnected (i.e. the plug of the connected electrical appliance is disconnected from the plug-in module 23), the spring 235 ensures that the plug-in module 23, the first conductive terminal 233, the second conductive terminal 234, and the third conductive terminal 2311 remain in the disconnected position, avoiding the risk of accidental power-on due to vibration or accidental contact, and at the same time providing a clear starting point and a certain buffer for the next power-on operation.

[0052] The arc-shaped through hole 212 on the transmission mechanism 21, in conjunction with the first linkage component 221 and the second linkage component 222, forms a precise rotation angle limiting fit. This arc-shaped through hole 212 is designed with a specific central angle range of 0° - 93°, which directly corresponds to the maximum effective stroke of the first linkage component 221 and the second linkage component 222 when driving the plug-in module 23 to switch on and off. This precisely limits the rotation angle of the linkage component driven by the gear 211, thereby ensuring that the first clamping portion 2213 and the second clamping portion 2223 at the ends of the first L-shaped conductive arm 2212 and the second L-shaped conductive arm 2222 can only move within the designed safe stroke. This reliably clamps or disengages the first conductive plate 111 and the second conductive plate 121, while effectively preventing damage to the mechanism or poor contact due to excessive rotation.

[0053] The rotation range of 0° to 93° provides clear feedback on the on / off endpoint, allowing users to clearly perceive the "on" and "off" states during rotation, thus improving the user experience and reliability.

[0054] In summary, the recessed hole 242 ensures ease of use of the user interface; the spring 235 provides automatic reset, position holding, and safety isolation in the event of power failure; and the limiting design of the arc-shaped through hole 212 precisely controls the on / off switching stroke, ensuring the reliability of the electrical connection and protecting the mechanism from damage. These three elements work together to form the foundation for the safe, reliable, and user-friendly operation of the sliding socket.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
