[0004] This utility model provides a side-plug adapter, which simplifies the power supply structure, reduces production costs, and improves safety and service life by setting a control block.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a side-plug adapter, including a socket body and a power-receiving body, the power-receiving body including a control block and a power-receiving shell, the control block being hinged to the base, the control block being provided with a connecting rod, the connecting rod being connected to the socket body; the power-receiving shell being provided with a first opening, the two ends of the control block being connected to the side of the contact piece through elastic elements, the top side of the contact piece being provided with a contact plate, the contact plate being disposed in the first opening.

[0006] Preferably, the contact plate is provided with contacts, and the control block controls the contact plate to extend or retract into the power-receiving housing through the first opening. The contact plate, contact piece, and connecting plate are in the same plane. When the control block tilts towards the contact plate on that side, the elastic element is compressed, causing the connecting plate to press down. The connecting plate drives the entire contact piece to press down, the contact plate extends out of the opening, and the contact extends, completing the power extraction. When you want to control the extension or retraction of the contact, simply rotate the socket body. The socket body controls the tilt of the control block through the connecting rod. The contact piece structure is simple, requiring no separate mold, saving costs and achieving modularity. A control seat is provided on the inner wall of the bottom end of the socket body. A control groove is provided at the center of the upper surface of the control seat. Both the control seat and the control groove are arc-shaped. The top of the control groove is open, and the connecting rod extends into the control groove and is movably connected to the control groove, that is, movably connected to the socket body. Rotating the socket body left and right causes the connecting rod to abut against the two side walls of the control groove, causing the control block to tilt left and right, thereby realizing the extension and retraction of the contact plate at the top of the contact piece through the opening, realizing power extraction and disconnection.

[0007] Preferably, a connecting plate is provided on one side of the bottom end of the contact piece. The connecting plate is connected to the elastic element, and the connecting plate and the contact plate are located on the same side of the contact piece. The connecting plate is perpendicular to the contact piece, and the contact plate is perpendicular to the contact piece. They are respectively located at the bottom and top of the contact piece. One side of the contact piece is longer, and the other side is shorter. The bottom ends of both are at the same height. This achieves synchronous linkage of the contact plates, ensuring accurate and reliable contact extension / retraction, improving power supply stability, and extending service life.

[0008] Preferably, the other side of the contact piece is provided with a guide fixing part, which is engaged in the V-shaped groove of the fixing plate. The longitudinal section of the guide part is V-shaped. The opening angle of the V-shaped groove of the fixing plate is greater than the included angle of the guide fixing part. The control block controls the contact piece to rotate around the fixing plate. When the contact plate extends out of the power receiving housing, the guide fixing part contacts the groove wall at the bottom. The V-shaped guide structure restricts the rotation trajectory of the contact piece, prevents offset and jamming, enhances the assembly fault tolerance, and improves safety and reliability.

[0009] Preferably, the control block has hinge rods on both sides, which are rotatably connected to the base, and there is a gap between the bottom of the control block and the base. This gap allows the control block room to tilt left and right, providing sway space, avoiding rigid collisions, reducing wear, and improving the durability of the mechanism.

[0010] Preferably, a button is located at the bottom of the power-gathering housing, and a push plate is connected to the button. The push plate is positioned below the base and connected to the base by a second elastic element. The button can extend into or out of the power-gathering housing, and the plane of the push plate and the plane of the connecting rod are parallel to each other. One-button trigger separation simplifies the operation steps, enables quick one-handed assembly and disassembly, and improves the user experience.

[0011] Preferably, push rods are connected to both sides of the push plate, and the ends of the push rods are provided with first guide slopes, which are inclined towards the socket body. The push rods and the push plate are set vertically, and the push plate is an arc-shaped plate. The first guide slope is used to push the rocker block to lift. The arc-shaped push plate distributes the pressing pressure, and the guide slope precisely drives the rocker block, resulting in smooth and jam-free operation and reducing the failure rate.

[0012] Preferably, the power receiving housing has a second opening, and a locking block is provided in the second opening.

[0013] Preferably, the outer surface of the locking block is inclined, with the inclined surface facing downwards. The top of the locking block is positioned inside the edge of the opening, and the bottom can extend out of the opening. The top of the locking block is hinged to the power-receiving housing. When the first guide slope pushes the pry bar up, the bottom of the locking block retracts into the power-receiving housing, achieving separation of the power-receiving body and the track. Utilizing the inclined surface self-locking principle, it automatically locks in place upon insertion and quickly disengages when the button is pressed, balancing convenience with anti-disengagement safety.

[0014] Preferably, a third elastic element connects the inner side of the locking block and the power-collecting housing. A pry bar is located at the bottom of the inner side of the locking block, and a second guide ramp is located above the push rod on the pry bar. The second guide ramp and the first guide ramp have the same inclination direction. This bidirectional ramp synchronous transmission ensures that the locking block retraction action is synchronous and reliable, avoiding track damage and extending the adapter's lifespan.

[0015] Beneficial effects: This utility model simplifies the power supply structure by controlling the extension and retraction of the contact plate, simplifying the power supply path, reducing screw dependence, and achieving rapid power supply; the V-shaped guide and elastic reset improve positioning accuracy and shock resistance, reduce wear, and extend service life; the button-linked locking block can be separated with one hand, which is safe and convenient, and significantly reduces production and maintenance costs.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In the field of power supply connections for electronic devices, the structural design of side-plug adapters directly affects power extraction efficiency, safety, and production costs. This invention addresses the problems of complex structures, high mold costs, and insufficient power extraction stability in traditional adapters by employing an innovative linkage design between the control block 1.3 and the contact piece 1.8 to construct a highly efficient and reliable side-plug power extraction system.

[0025] like Figure 1 and Figure 2As shown, the side-mounted adapter consists of two core parts: the socket body 2 and the power-generating body 1. The power-generating body 1, serving as the core carrier for the power-generating function, includes a control block 1.3 and a power-generating housing 1.1. The control block 1.3 is hinged to the base 1.5, allowing it to rotate and tilt flexibly, providing a foundation for subsequent power-generating control. A connecting rod 1.6 is connected to the control block 1.3, with its other end connected to the socket body 2, forming a transmission link of "socket body 2—connecting rod 1.6—control block 1.3". When the user operates the socket body 2, the rotational force is transmitted to the control block 1.3 through the connecting rod 1.6, causing the control block 1.3 to tilt and triggering the power-generating action. The power-generating housing 1.1 serves as external protection and structural support, with a first opening 1.1.1. This opening is the channel for the contact plate 1.9 to extend and retract, and is also a key interface for current transmission during power generation. The two ends of the control block 1.3 are connected to the sides of the contact piece 1.8 via elastic elements 1.7. The elastic elements 1.7 are usually made of materials with good elastic reset properties. In this embodiment, a spring is preferred, which can both transmit the force of the control block 1.3 and drive the contact piece 1.8 back to its original position when the control block 1.3 resets. A contact plate 1.9 is provided on one side of the top of the contact piece 1.8. The contact plate 1.9 is precisely adapted to the position of the first opening 1.1.1. In its natural state, it is hidden inside the power supply housing 1.1. When power is drawn, it extends out of the opening through the drive of the control block 1.3 to achieve a conductive connection with external devices.

[0026] like Figure 3 and Figure 5 As shown, the contact plate 1.9 is equipped with conductive contacts 1.11, whose extension and retraction states are precisely controlled by the control block 1.3. The contact plate 1.9, contact piece 1.8, and connecting plate 1.10 are in the same plane. This coplanar design ensures the linearity of force transmission and reduces resistance and deviation during movement. When power is needed, the user rotates the socket body 2, which, through the connecting rod 1.6, causes the control block 1.3 to tilt to one side. When the control block 1.3 tilts, the elastic element 1.7 on one side is compressed, and the pressure is transmitted to the contact piece 1.8 through the connecting plate 1.10. After being stressed, the contact piece 1.8 rotates around the fixed plate 1.20, and the contact plate 1.9 at the top extends out of the first opening 1.1.1 of the power-taking housing 1.1, exposing the contact 1.11, thus completing the preparation for power taking. When power taking ends, the socket body 2 is rotated in the opposite direction, and the control block 1.3 returns to its original position under the restoring force of the elastic element 1.7. The contact piece 1.8 drives the contact plate 1.9 to retract into the power-taking housing 1.1, and the contact 1.11 is hidden, thus terminating power taking. This contact piece 1.8 structure design is highly advantageous. It eliminates the need to make complex molds for separate transmission components, and achieves functionality through the bending and connection of the contact piece 1.8 itself, significantly saving production costs. At the same time, it realizes modular assembly, facilitating mass production and maintenance replacement, and improving production efficiency.

[0027] like Figure 2 and Figure 4 As shown, the structural details of contact 1.8 further optimize the stability and reliability of power extraction. A connecting plate 1.10 is provided on one side of the bottom of contact 1.8. The connecting plate 1.10 is firmly connected to the elastic element 1.7, becoming the point of force reception for the elastic element 1.7. The connecting plate 1.10 and the contact plate 1.9 are located on the same side of contact 1.8, and both are perpendicular to contact 1.8, respectively positioned at the bottom and top of contact 1.8—the connecting plate 1.10 receives the force of the elastic element 1.7 at the bottom, and the contact plate 1.9 performs the power extraction action at the top. Contact 1.8 comes in two lengths, one longer and one shorter, but both have their bottom ends at the same height. The two contact plates 1.9 move in sync: when the control block 1.3 tilts, the long and short contact pieces 1.8 rotate at the same rhythm under the action of the elastic element 1.7 and the connecting plate 1.10, and the contact plates 1.9 extend or retract simultaneously, avoiding poor power contact caused by lag in unilateral movement. This synchronous linkage mechanism ensures precise and reliable contact extension and retraction, reduces potential hazards such as sparks and poor contact during power extraction, significantly improves power extraction stability, and extends the adapter's lifespan.

[0028] like Figure 3 and Figure 5 As shown, a guide fixing part 1.21 is provided on the other side of the contact piece 1.8. This part cooperates with the V-shaped groove of the fixing plate 1.20 to form a precise motion guiding system. The longitudinal section of the guide fixing part 1.21 is V-shaped, which fits perfectly into the V-shaped groove of the fixing plate 1.20. The fit of the V-shaped structure has been precisely calculated to ensure the flexibility of the contact piece 1.8 during rotation while limiting its movement trajectory. The opening angle of the V-shaped groove of the fixing plate 1.20 is greater than the included angle of the V-shape of the guide fixing part 1.21. This angle difference design provides sufficient space for the rotation of the contact piece 1.8 and avoids jamming problems caused by dimensional errors. When the control block 1.3 controls the contact piece 1.8 to rotate around the fixing plate 1.20 and the contact plate 1.9 extends out of the power receiving housing 1.1, the side of the guide fixing part 1.21 will contact the groove wall at the bottom of the V-shaped groove. The groove wall provides support and limit for the guide fixing part 1.21, preventing the contact piece 1.8 from rotating excessively or deviating. The V-shaped guide structure acts like a "track," strictly limiting the rotation trajectory of the contact piece 1.8 and ensuring that the contact plate 1.9 always extends precisely along the preset path from the first opening 1.1.1. This effectively prevents the contact piece 1.8 from shifting or jamming due to vibration or external impact. This design enhances the fault tolerance during assembly. Even with minor dimensional deviations in components, the V-shaped structure can correct these deviations through its guiding effect, ensuring stable power supply and significantly improving the adapter's safety and reliability.

[0029] In practical use, the advantages of this side-plug adapter are fully demonstrated. When the user needs power, simply rotate the socket body 2 gently. The connecting rod 1.6 tilts the control block 1.3, and the elastic element 1.7 compresses and transmits force to the contact piece 1.8. Under the constraint of the V-shaped guide structure, the contact piece 1.8 rotates precisely, and the contact plate 1.9 extends from the first opening 1.1.1, quickly completing the power connection. After power is supplied, rotate the socket body 2 in the opposite direction. The control block 1.3 resets, the elastic element 1.7 drives the contact piece 1.8 back, and the contact plate 1.9 retracts into the housing, disconnecting the connection. The entire process is simple to operate, requiring no complicated plugging and unplugging actions, reducing component wear. The modular design of the contact piece 1.8 eliminates the cost of manufacturing a separate mold, the V-shaped guide and synchronous linkage structure ensure the stability and safety of power supply, and the reset function of the elastic element 1.7 extends the service life of the components. Whether for everyday household power needs, office equipment connections, or temporary power needs in industrial settings, this side-plug adapter can meet diverse power requirements thanks to its simplified structure, reliable performance, and low cost, demonstrating significant practical value and promising prospects in the field of electronic connectivity.

[0030] like Figure 6 As shown, a control base 2.1 is carefully installed on the inner wall of the bottom of the socket body 2. As a key structure connecting the socket body and the control components, the control base 2.1's overall design matches the curvature of the socket body's inner wall. A control groove 2.2 is formed at the center of the upper surface of the control base 2.1. Both the control base 2.1 and the control groove 2.2 adopt an arc-shaped design. This arc-shaped structure matches the movement trajectory of the entire adapter, providing a spatial basis for subsequent flexible operation. The top of the control groove 2.2 is open, facilitating the insertion and movement of the connecting rod.

[0031] One end of the connecting rod 1.6 extends into the control groove 2.2, forming a movable connection with it, and thus achieving a movable connection with the socket body 2. This movable connection allows the connecting rod to move freely within the control groove, providing a transmission path for the tilting action of the control block. When the user needs to access or disconnect power, they only need to rotate the socket body 2 left or right. The rotation of the socket body will cause the control seat 2.1 on the inner wall to rotate synchronously. As the control seat rotates, the two side walls of the control groove 2.2 will respectively abut against the connecting rod 1.6 extending into the groove.

[0032] When the connecting rod 1.6 abuts against one side wall of the control slot 2.2, the connecting rod will push the control block 1.3 to tilt to that side under the action of rotational force; similarly, when the rotation direction changes and the connecting rod abuts against the other side wall, the control block will tilt to the other side. The left and right tilting of the control block will further drive the connected contact piece 1.8 to move, and the contact plate 1.9 at the top of the contact piece will extend or retract the first opening 1.1.1 of the power supply housing as the contact piece moves. When the contact plate extends out of the first opening, the adapter completes the power supply preparation and realizes the power supply function; when the contact plate retracts into the first opening, the power supply circuit is disconnected and the power-off operation is realized. The whole process cleverly realizes the convenient switching between power supply and power-off through the rotation of the socket body, the transmission of the control slot and the connecting rod, the tilting of the control block, and the linkage of the contact piece. The structure is compact and the transmission is efficient.

[0033] like Figure 2 As shown, in the structural design of the side-plug adapter, the flexible swing of the control block 1.3 and the precise linkage of components are the core of achieving stable power supply and convenient operation. The control block 1.3 has hinge rods 1.4 on both sides, forming a rotatable connection with the base 1.5 through the hinge rods 1.4. This connection method gives the control block 1.3 the ability to tilt flexibly around the hinge point. The gap reserved between the bottom of the control block 1.3 and the base 1.5 provides ample space for its swing. When the user rotates the socket body 2 to tilt the control block 1.3 via the connecting rod 1.6, the gap avoids rigid collisions between the control block 1.3 and the base 1.5—traditional rigid connections are prone to wear and even breakage due to frequent swinging. This gap allows the control block 1.3 to remain in a non-contact state during tilting, significantly reducing mechanical wear, greatly improving the durability of the mechanism, and ensuring that it maintains flexible control performance even after long-term use.

[0034] like Figure 2As shown, the button 1.18 at the bottom of the power housing 1.1 provides a convenient operating interface for the quick disconnection function of the adapter. The button 1.18 is connected to the push plate 1.17, which is horizontally positioned below the base 1.5. The plane of the push plate 1.17 is parallel to the plane of the connecting rod 1.6. This parallel arrangement ensures that when the button 1.18 is subjected to force, the push plate 1.17 can move smoothly in a straight line, avoiding any deviation in force transmission. The second elastic element 1.2 connecting the push plate 1.17 and the base 1.5 is in a naturally extended state when the button 1.18 is not pressed, supporting the push plate 1.17 to maintain its original position. When the button 1.18 is pressed, the second elastic element 1.2 is compressed and stores elastic potential energy. After the button 1.18 is released, the elastic element resets, causing the push plate 1.17 and the button 1.18 to return to their initial positions, achieving automatic rebound. The push rods 1.16 connected to both sides of the push plate 1.17 extend perpendicularly to the push plate 1.17. The first guide slope 1.13 at the end of the push rod 1.16 is inclined towards the socket body 2. This inclination angle is precisely designed to lay the foundation for the subsequent inclined surface transmission with the rocker arm 1.15. The push plate 1.17 adopts an arc-shaped design. The arc structure can evenly distribute the pressing pressure of the button 1.18 to the entire push plate 1.17 and push rod 1.16, avoiding excessive local stress that could lead to deformation, enhancing the structural strength of the components, and reducing the failure rate.

[0035] like Figure 1 As shown, the second opening 1.1.2 on the power receiving housing 1.1 provides ample installation space for the locking block 1.12 and also provides the necessary range of motion for the locking block 1.12 to extend and retract within the power receiving housing 1.1. As a key component for reliable fixing between the adapter and the external rail, the locking block 1.12's overall outline and internal structure are carefully designed. It can automatically lock upon insertion and quickly release the lock through simple operation when separation is required, balancing long-term locking stability with convenient temporary disassembly and assembly. The outer surface of the locking block 1.12 is machined into an inclined surface 1.19, which gradually tapers inward from top to bottom, forming a smooth guiding angle. The top of the locking block 1.12 is connected to the corresponding position on the power receiving housing 1.1 through a hinge structure, allowing the locking block 1.12 to swing flexibly around this hinge point as its rotation center, thus smoothly completing the extension and retraction actions. A third elastic element is arranged between the inner side of the locking block 1.12 and the inner wall of the power supply housing 1.1. This elastic element always applies an outward elastic force to the locking block 1.12, ensuring that the locking block 1.12 can maintain the tendency to pop outward when it is not disturbed by external forces, thereby ensuring that the locking state with the external track is stable and reliable and is not easy to loosen due to vibration or accidental contact.

[0036] like Figure 4As shown, the rocker arm 1.15 at the bottom inner side of the locking block 1.12 is the key transmission component for achieving separation. A second guide slope 1.14 is located above the rocker arm 1.15, and the second guide slope 1.14 has the same inclination direction as the first guide slope 1.13 of the push rod 1.16. When the button 1.18 is pressed, the push plate 1.17 drives the push rod 1.16 forward. The first guide slope 1.13 at the end of the push rod 1.16 contacts the second guide slope 1.14 of the rocker arm 1.15. Since the two slopes have the same inclination direction, the thrust is smoothly transmitted through the slopes, forcing the rocker arm 1.15 to rotate upwards, which in turn drives the locking block 1.12 to rotate inwards around the top hinge point. The bottom end of the locking block 1.12 retracts into the power receiving housing 1.1, disengaging from the track slot, thus achieving rapid separation of the adapter from the track. After releasing button 1.18, the second elastic element 1.2 drives the push plate 1.17 and push rod 1.16 to reset, and the third elastic element pushes the locking block 1.12 to rotate outward, with its bottom end extending out of the second opening 1.1.2, restoring the locking capability. This bidirectional inclined synchronous transmission design ensures the accuracy and reliability of the extension and retraction of the locking block 1.12, avoiding damage to the track or locking block 1.12 caused by transmission jamming, and effectively extending the service life of the adapter.

[0037] The entire adapter's workflow is seamlessly integrated: When power is drawn, rotating the socket body 2 causes the control block 13 to tilt via the connecting rod 1.6. The control block 1.3 compresses the elastic element 1.7, pushing the contact piece 1.8. The contact piece 1.8 rotates under the constraint of the V-shaped guide structure, and the contact plate 1.9 extends from the first opening 1.1.1 to complete power drawing. When the adapter is fixed to the rail, the locking block 1.12 automatically slides into the slot with the help of the inclined surface 1.19 on its outer side, and the third elastic element ensures that it is locked. When separation is required, pressing the button 1.18 drives the push plate 1.17 and the push rod 1.16, which force the locking block 1.12 to retract through the transmission of the first and second guide inclined surfaces 1.14, achieving rapid separation. After releasing the button 1.18, the elastic element 1.7 resets, and the components return to their initial state.

[0038] This structural design offers significant advantages: the linkage between control block 1.3 and contact piece 1.8 simplifies the power supply path, reduces the use of screws and other connecting parts, and lowers assembly complexity; the V-shaped guide structure restricts the movement trajectory of contact piece 1.8, and, in conjunction with the reset function of elastic element 1.7, improves positioning accuracy and shock resistance, reducing component wear; the inclined transmission between button 1.18 and locking block 1.12 enables convenient one-handed operation, balancing safety and efficiency. Through the synergistic effect of each component, this side-plug adapter ensures stable power supply and reliable fixation while significantly reducing production and maintenance costs, extending service life, and meeting the diverse application needs.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
