Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and particularly to a power-taking track. Background Art

[0002] As a modular power supply device, track sockets have been widely used in recent years due to their flexibility and convenience. As shown in the prior art (CN222029438U), a plurality of fixed power-taking positions are arranged along the length direction of the track base, and the socket adapter can be plugged into any power-taking position to achieve position adjustment. Although this solution avoids the traditional chute structure, it still has the following safety defects: Insufficient protection and sealing of the socket: Although a safety door assembly is provided above the conductive plug-in end inside the track base in the prior art, it only covers the conductive end and does not seal the second socket (i.e., the cover plate socket) on the cover plate. When the adapter is not plugged in, the cover plate socket is in an open state, and liquid or foreign objects can directly invade the inside of the track through the socket, resulting in the risk of short circuit or electric leakage. At the same time, the cover plate partially seals the insertion slot through the protruding part, but the design redundancy between the insertion slot and the socket still results in insufficient sealing, especially in a humid or splashing environment, the hidden danger is significant. The above problems indicate that the prior art fails to achieve comprehensive protection of the power-taking track socket, and an improved solution that can both seal the socket and simplify the structure is urgently needed to improve the overall safety and reliability. In view of the above problems, the prior art urgently needs to be improved. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide a power-taking track, which has the advantages of improving socket protection and sealing, simplifying the structure, and enhancing safety and reliability.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] The present application provides a power-taking track, and the technical solution is as follows: A power-taking track includes a track base, a conductive component disposed inside the track base, a support plate, and a sealing plate longitudinally movably disposed between the support plate and the top plate of the track base. A plurality of power-taking positions are arranged along the length direction of the track base, and sealing plate sockets corresponding to the plurality of power-taking positions are provided on the sealing plate. The power-taking track further includes a safety door assembly, and the safety door assembly includes a protection door slidably disposed horizontally on the support plate. The protection door is provided with a neutral wire convex column, a live wire convex column, and a ground wire convex column corresponding to the sealing plate socket of each power-taking position. When the power-taking position is not plugged with a socket adapter, the neutral wire convex column, the live wire convex column, and the ground wire convex column of the protection door close the sealing plate socket. When the socket adapter is inserted into the power-taking position, its neutral wire plug, live wire plug, and ground wire plug press down the corresponding neutral wire convex column, live wire convex column, and ground wire convex column, driving the protection door to move downward and horizontally to avoid the plug, so that the sealing plate socket is opened. The protection door is elastically connected to the support plate or the track base through a return spring and is used for resetting after the socket adapter is removed.

[0006] Further, the present application also proposes that guide sliding rails are provided on the inner side wall of the track base, and sliding columns are provided on both sides of the protection door. The sliding columns are embedded in the guide sliding rails. The path of the guide sliding rails is configured such that when the protection door is pressed down by the plug, the sliding columns slide along the guide sliding rails to guide the protection door to move downward and horizontally.

[0007] Further, the present application also proposes that a cover plate is fixed above the support plate, and the protection door is slidably disposed between the support plate and the cover plate. A top sliding groove hole is provided on the cover plate, and the neutral wire convex column, the live wire convex column, and the ground wire convex column of the protection door are embedded in the top sliding groove hole and can move horizontally along it.

[0008] Further, the present application also proposes that side sliding groove holes are provided between the side walls of the support plate and the cover plate. The sliding columns pass through the side sliding groove holes and extend into the guide sliding rails. The guide sliding rails are provided on the inner side walls on both sides of the track base, and the sliding columns are provided on both sides of the protection door.

[0009] Further, the present application also proposes that a spring groove is provided on the protection door, the support plate, or the cover plate, and the return spring is installed in the spring groove, with one end propping against the protection door and the other end propping against the support plate or the cover plate.

[0010] Further, the present application also proposes that a groove is provided on the bottom plate inside the track base, and a ground wire contact, a live wire contact, and a neutral wire contact of the conductive component are fixed in the groove; a base is provided above the groove, and a guiding slide rail is provided on the side wall of the base; the end corners of the support plate are elastically supported on the base by a first spring, and a base socket corresponding to the sealing plate socket is provided on the base and the support plate; the sealing plate is elastically supported on the base by a second spring.

[0011] Further, the present application also proposes that arc-shaped pieces are provided at the four end corners of the base, a spring cavity is formed inside the arc-shaped pieces, and an opening penetrating up and down is provided on one side of the spring cavity; feet are provided at the four end corners of the support plate, and the feet are embedded from the top of the spring cavity and supported by a first spring, and the end of the feet is larger than the diameter of the opening.

[0012] Further, the present application also proposes that a slot is constructed on the top plate of the track housing, a protrusion is provided on the top of the sealing plate, and the sealing plate socket is opened on the protrusion; when the sealing plate is lifted to support on the lower end surface of the top plate on both sides, the protrusion is embedded and at least partially closes the slot.

[0013] Further, the present application also proposes that elastic arms are symmetrically provided on both sides of the middle of the bottom surface of the protection door, and the elastic arms elastically support the protection door on the bottom surface of the support plate, so that a lateral sliding gap is formed between the support plate and the protection door and the protection door is kept in a horizontal position.

[0014] Further, the present application also proposes that the ground wire stud is located in the middle of the protection door, and the neutral wire stud and the live wire stud are arranged on both sides; hooks are provided at the lower ends of the neutral wire stud and the live wire stud. When one-sided studs are pressed down, the hooks are caught in the base socket of the support plate to limit the lateral movement of the protection door; when both-sided studs are pressed down simultaneously, the protection door and the support plate move downward synchronously and are guided to move laterally through the guiding slide rail.

[0015] As can be seen from the above, a power-taking track and its safety door assembly provided by the present application solve the problem of insufficient protection and sealing of the socket in the prior art by providing a safety door assembly and a closed structure of the sealing plate socket, and have the advantages of improving the protection and sealing of the socket, simplifying the structure, and improving safety and reliability.

[0028] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more, unless otherwise clearly defined.

[0029] In the present invention, unless otherwise clearly specified or limited, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the present invention, unless otherwise clearly specified or limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween.

[0031] As Figures 1-10 shown, this embodiment relates to a power-taking track, which includes a track base 1, a conductive component arranged inside the track base 1, a support plate 12, and a sealing plate 4 longitudinally and movably arranged between the support plate 12 and the top plate of the track base 1. A plurality of power-taking positions 10 are arranged along the length direction of the track base 1, and sealing plate sockets 43 corresponding to the plurality of power-taking positions 10 are arranged on the sealing plate 4. The power-taking track further includes a safety door assembly, and the safety door assembly includes a protection door 6 slidably arranged horizontally on the support plate 12. Zero-line protrusions 61, live-line protrusions 62, and ground-line protrusions 63 corresponding to the sealing plate sockets 43 of each power-taking position 10 are arranged on the protection door 6. When the power-taking position 10 is not plugged with a socket adapter 2, the zero-line protrusion 61, live-line protrusion 62, and ground-line protrusion 63 of the protection door 6 close the sealing plate socket 43. When the socket adapter 2 is inserted into the power-taking position 10, its zero-line plug 221, live-line plug 222, and ground-line plug 223 press down the corresponding zero-line protrusion 61, live-line protrusion 62, and ground-line protrusion 63, driving the protection door 6 to move downward and horizontally to avoid the plugs, so that the sealing plate socket 43 is opened. The protection door 6 is elastically connected to the support plate 12 or the track base 1 through a return spring 64 for resetting after the socket adapter 2 is removed.

[0032] Among them, the neutral pole 61, live wire pole 62, and ground wire pole 63 of the protection door 6 can adopt cylindrical, square, or other geometric shapes, and their sizes and shapes can be adjusted according to the specific design of the sealing plate socket 43 to ensure that the socket can be completely closed. The lateral sliding of the protection door 6 can be achieved through guide rails, chutes, or other guiding structures. Further, the sliding path of the protection door 6 can be precisely controlled by the guiding slide rail 71 to ensure that it can smoothly move and open the socket when the socket adapter 2 is inserted. The return spring 64 can be selected from coil springs, leaf springs, or other elastic elements, and its installation position and connection method can be adjusted according to specific design requirements.

[0033] This technical solution solves the problem that the power-taking track socket cannot be completely closed when the socket adapter 2 is not plugged in by introducing a safety door component. Specifically, the corresponding relationship between the neutral pole 61, live wire pole 62, and ground wire pole 63 of the protection door 6 and the sealing plate socket 43 ensures that the socket is in a closed state when not in use, preventing liquids or foreign objects from entering the inside of the track. When the socket adapter 2 is inserted, its plug post presses down on the poles of the protection door 6, driving the protection door 6 to move and open the socket to ensure the smooth progress of the plugging. The setting of the return spring 64 enables the protection door 6 to automatically reset after the socket adapter 2 is removed and re-close the socket. Compared with the prior art, this solution effectively improves the safety and reliability of the power-taking track through the dynamic closing mechanism of the protection door 6 and makes the overall appearance of the product more beautiful.

[0034] In Figures 5-7 In the specific implementation shown, guiding slide rails 71 are provided on the inner side walls of the track base 1, and sliding posts 65 are provided on both sides of the protection door 6. The sliding posts 65 are embedded in the guiding slide rails 71. The path of the guiding slide rails 71 is configured such that when the protection door 6 is pressed down by the plug post, the sliding posts 65 slide along the guiding slide rails 71, guiding the protection door 6 to move downward and laterally.

[0035] Specifically, the path design of the guiding slide rail 71 can include a combination of a straight segment and a curved segment / inclined segment. The straight segment is used to guide the protection door 6 to move downward, and the curved segment / inclined segment is used to guide the protection door 6 to move laterally. As a preferred implementation, the curved segment of the guiding slide rail 71 can be designed as an arc to reduce the frictional resistance of the sliding column 65 during movement and ensure the smooth movement of the protection door 6. In addition, the material of the guiding slide rail 71 can be selected as a metal or composite material with high wear resistance to extend its service life. In this regard, the sliding column 65 of the protection door 6 can be designed in a cylindrical or spherical shape. The cylindrical sliding column 65 has high sliding stability within the guiding slide rail 71, while the spherical sliding column 65 can provide greater flexibility when moving in multiple directions. Further, the surface of the sliding column 65 can be coated with a lubricating coating to reduce the friction with the guiding slide rail 71 and improve the accuracy and stability of the movement of the protection door 6. Thus, through the cooperation of the guiding slide rail 71 and the sliding column 65, this technical solution realizes the accurate and stable movement of the protection door 6 when pressed by the insertion post. Compared with the prior art, this solution avoids the problems of deviation or jamming of the protection door 6 during movement and improves the working reliability and safety of the protection door 6. Specifically, the path configuration of the guiding slide rail 71 ensures the controllability of the trajectory of the protection door 6 during movement, and the close cooperation between the sliding column 65 and the guiding slide rail 71 further enhances the stability of the movement of the protection door 6. Therefore, this technical solution effectively solves the technical problem that the protection door 6 can move accurately and stably downward and laterally when pressed by the insertion post.

[0036] Further, a cover plate 72 is fixed above the support plate 12, and the protection door 6 is slidably disposed between the support plate 12 and the cover plate 72. A top chute hole 721 is provided on the cover plate 72, and the neutral pole stud 61, the live pole stud 62, and the ground pole stud 63 of the protection door 6 are embedded in the top chute hole 721 and can move laterally along it. The design of the top chute hole 721 enables the studs of the protection door 6 to move freely within the chute hole of the cover plate 72, thus solving the problem of the lateral movement of the studs when the protection door 6 slides. As a preferred embodiment, the top chute hole 721 can be designed as a long strip, and its length direction is consistent with the sliding direction of the protection door 6 to ensure smooth movement of the studs within the chute hole. In addition, the width of the chute hole can be slightly larger than the diameter of the stud to reduce friction and improve sliding efficiency. Further, limit structures can be provided at both ends of the chute hole to prevent the studs from sliding out of the chute hole. Thus, through this technical solution, the protection door 6 can remain stable when sliding, and at the same time, the lateral movement of the studs is effectively controlled. Compared with the prior art, this solution not only simplifies the structure but also improves the safety and reliability of the power-taking track. Specifically, the protection door 6 always cooperates with the support plate 12 and does not disengage, ensuring stability during the sliding process. At the same time, the free movement of the studs within the chute hole avoids jamming or damage caused by lateral movement, further improving the service life and safety of the device.

[0037] Furthermore, a side chute hole 731 is provided between the side wall of the support plate 12 and the cover plate 72. The sliding column 65 passes through the side chute hole 731 and extends into the guiding slide rail 71. Guiding slide rails 71 are provided on the inner side walls on both sides of the track base 1, and sliding columns 65 are provided on both sides of the protection door 6. Among them, the setting of the side chute hole 731 enables the sliding column 65 to slide between the support plate 12 and the cover plate 72. At the same time, the setting of the guiding slide rail 71 further defines the sliding path of the sliding column 65, ensuring the stability and accuracy of the protection door 6 during the sliding process. Through the cooperation of the side chute hole 731 and the guiding slide rail 71, the protection door 6 can slide smoothly between the support plate 12 and the cover plate 72 and will not deviate or jam during the sliding process, thereby improving the use effect and safety of the protection door 6. Specifically, the design of the side chute hole 731 can include various implementation methods. For example, the side chute hole 731 can be linear, curved or combined to adapt to different sliding path requirements. In addition, the width and depth of the side chute hole 731 can be adjusted according to the size of the sliding column 65 to ensure that the sliding column 65 will not shake or break away during the sliding process. The design of the guiding slide rail 71 can also have various variations. For example, the guiding slide rail 71 can be arranged on one side or both sides to further increase the stability of the sliding column 65. The material of the guiding slide rail 71 can be selected as wear-resistant and corrosion-resistant materials to extend its service life. Thus, through the cooperation of the side chute hole 731 and the guiding slide rail 71, this technical solution effectively solves the guiding and limiting problems of the sliding column 65 when the protection door 6 slides between the support plate 12 and the cover plate 72. Compared with the prior art, this solution not only improves the stability and accuracy of the sliding of the protection door 6, but also simplifies the structural design, reduces the friction and wear during the sliding process, thereby enhancing the overall use effect and safety.

[0038] Such as Figure 6As shown, a spring groove 66 is provided on the protection door 6, the support plate 12 or the cover plate 72. The return spring 64 is embedded in the spring groove 66, with one end propping against the protection door 6 and the other end propping against the support plate 12 or the cover plate 72. The specific design of the spring groove 66 can include various forms. For example, the spring groove 66 can be designed as a U-shaped groove or a rectangular groove, and its depth and width are adapted according to the size of the return spring 64 to ensure that the return spring 64 can be stably embedded therein. The inner wall of the spring groove 66 can be provided with anti-slip lines or protrusions to increase the friction between the return spring 64 and the groove wall and prevent the spring from sliding or shifting during movement. In addition, the position of the spring groove 66 can be optimized according to the movement trajectory of the protection door 6. For example, it can be set at the bottom or side of the protection door 6 to ensure that the return spring 64 can effectively apply an elastic force when the protection door 6 moves. Specifically, one end of the return spring 64 props against the protection door 6 and the other end props against the support plate 12 or the cover plate 72. This design enables the return spring 64 to always maintain a stable support relationship during the movement of the protection door 6. When the socket adapter 2 is inserted, the protection door 6 is subjected to a downward pressure and moves, and the return spring 64 is compressed. When the socket adapter 2 is removed, the return spring 64 pushes the protection door 6 back to its original position through the elastic force, thereby realizing the automatic reset function of the protection door 6. The setting of the spring groove 66 not only simplifies the installation structure of the return spring 64 but also improves the fixing effect of the return spring 64, avoiding the problems of the spring falling off or shifting during movement. Compared with the prior art, the technical solution of the present application significantly improves the installation stability of the return spring 64 and the reset reliability of the protection door 6 through the design of the spring groove 66. The spring groove 66 provides an accurate installation position for the return spring 64 to ensure that it can always be in the correct working state during the movement of the protection door 6. In addition, the structure of the spring groove 66 is simple, easy to process and assemble, reducing the production cost and process complexity. This design not only solves the installation and fixing problems of the return spring 64 on the protection door 6, the support plate 12 or the cover plate 72 but also further improves the safety and reliability of the power-taking track during use.

[0039] As Figure 5As shown, a groove 81 is provided on the bottom plate inside the track base 1, and a ground wire contact 82, a live wire contact 83, and a neutral wire contact 84 of the conductive component are fixed in the groove 81. Above the groove 81, a base 86 is provided, and a guiding slide rail 71 is provided on the side wall of the base 86. The end corners of the support plate 12 are elastically supported on the base 86 by a first spring 85, and a base socket 42 corresponding to the seal plate socket 43 is provided on the base 86 and the support plate 12. The seal plate 4 is elastically supported on the base 86 by a second spring 41. Among them, the design of the groove 81 enables the ground wire contact 82, the live wire contact 83, and the neutral wire contact 84 of the conductive component to be firmly fixed inside the track base 1, avoiding poor contact or damage caused by vibration or external force. The setting of the base 86 not only provides support for the support plate 12, but also ensures the stability of the protection door 6 during movement through the guiding slide rail 71 on its side wall, preventing deviation or jamming. The end corners of the support plate 12 are elastically supported on the base 86 by a first spring 85, enabling the support plate 12 to maintain elastic support under the action of the spring and ensuring the accurate alignment of the seal plate socket 43. The seal plate 4 is elastically supported on the base 86 by a second spring 41, further ensuring the accurate alignment and sealing performance of the seal plate socket 43. Specifically, the shape and size of the groove 81 can be adjusted according to the specific requirements of the conductive component to achieve the best fixing effect. The material of the base 86 can be selected as a high-strength and wear-resistant material to enhance its service life and stability. The elastic coefficients of the first spring 85 and the second spring 41 can be adjusted according to the actual application scenario to ensure that the support plate 12 and the seal plate 4 can maintain good elastic support under different working conditions. The path of the guiding slide rail 71 can be further optimized to guide the protection door 6 to move more smoothly, reducing friction and resistance. Thus, through the coordinated action of the groove 81, the base 86, the guiding slide rail 71, the first spring 85, and the second spring 41, this technical solution effectively solves the technical problems of the fixation of the conductive component inside the track base 1 and the setting of the guiding slide rail 71. Compared with the prior art, this solution not only improves the fixing stability of the conductive component, but also ensures the smooth movement of the protection door 6 through the design of the guiding slide rail 71. At the same time, through the elastic support of the spring, it ensures the accurate alignment and sealing performance of the seal plate socket 43, thereby enhancing the safety and reliability of the overall equipment.

[0040] Furthermore, arc-shaped pieces 87 are provided at the four end corners of the base 86. A spring chamber 88 is formed inside the arc-shaped piece 87. An opening 89 that penetrates up and down is provided on one side of the spring chamber 88. Support feet 90 are provided at the four end corners of the support plate 12. The support feet 90 are inserted into the spring chamber 88 from the top and are supported by the first spring 85. The end of the support foot 90 is larger than the diameter of the opening 89. Specifically, the shape of the arc-shaped piece 87 can be adjusted according to actual needs. For example, a semi-circular shape, an elliptical shape, or other arc-shaped structures can be adopted to ensure the stability and elastic support effect of the spring chamber 88. The opening 89 of the spring chamber 88 can be designed in a circular shape, a square shape, or other shapes to adapt to the insertion and limiting requirements of the support feet 90. The end of the support foot 90 can be designed in a spherical shape, a conical shape, or other shapes to ensure that it is larger than the diameter of the opening 89, thereby achieving an effective limiting function. The material and elastic coefficient of the first spring 85 can be selected according to actual needs to ensure the elastic support effect of the support plate 12 on the base 86. In this regard, through the design of the arc-shaped piece 87 and the spring chamber 88, the elastic support of the support plate 12 on the base 86 is achieved. At the same time, through the design that the end of the support foot 90 is larger than the diameter of the opening 89, the movement range of the support plate 12 is limited, ensuring the stability and limiting effect of the support plate 12 on the base 86. Compared with the prior art, this solution not only simplifies the structure but also improves the stability and safety of the support plate 12, effectively solving the problems of elastic support and limiting between the base 86 and the support plate 12.

[0041] Furthermore, a slot 111 is formed on the top plate of the track housing 11, a protrusion 44 is provided on the top of the sealing plate 4, and the sealing plate socket 43 is formed on the protrusion 44. When the sealing plate 4 is lifted to support on both sides against the lower end surface of the top plate, the protrusion 44 is inserted into and at least partially closes the slot 111. Among them, the slot 111 can be formed by opening a long and narrow opening on the top plate of the track housing 11, and the width and length of the opening can be adjusted according to actual needs to ensure that the protrusion 44 of the sealing plate 4 can be smoothly inserted. The protrusion 44 of the sealing plate 4 can be realized by arranging a convex structure on the top of the sealing plate 4, and the shape and size of the convex structure should match the slot 111 to ensure a tight fit during insertion. The sealing plate socket 43 can be opened at the center of the protrusion 44, and its shape and size should correspond to the power taking position 10 so that the socket adapter 2 can be smoothly inserted. When the sealing plate 4 is lifted, its two sides support against the lower end surface of the top plate, enabling the protrusion 44 to be inserted into the slot 111, thereby realizing partial closure of the slot 111. Thus, through the design of the protrusion 44 of the sealing plate 4 being inserted into the slot 111, this technical solution realizes partial closure of the slot 111. This structure not only plays a role in aesthetics but also has a dust-proof effect. Combined with the sealing solution of the sealing plate socket 43, it can prevent liquid or foreign objects from invading the track interior through the socket, reducing the risk of short circuit or electric leakage. Compared with the prior art, this solution not only simplifies the structure but also improves the sealing performance and safety, especially being more remarkable in a humid or splash environment.

[0042] Such as Figure 3, As shown in FIGS. 5 - 7, elastic arms 67 are symmetrically arranged on both sides of the middle part of the bottom surface of the protection door 6. The elastic arms 67 elastically support the protection door 6 on the bottom surface of the support plate 12, forming a lateral sliding gap between the support plate 12 and the protection door 6 and keeping the protection door in a horizontal position. Specifically, the design of the elastic arms 67 enables the protection door 6 to slide laterally flexibly when subjected to a downward pressure, while maintaining an elastic connection with the support plate 12. As a preferred embodiment, the elastic arms 67 can be made of an elastic metal material or plastic material, and their shape can be a curved sheet structure or a spring structure. One end of the elastic arm 67 is fixed to the bottom surface of the protection door 6, and the other end contacts the bottom surface of the support plate 12, achieving the lateral sliding of the protection door 6 through elastic deformation. In addition, the symmetrical arrangement of the elastic arms 67 can ensure that both sides of the protection door 6 are evenly stressed when subjected to a downward pressure, avoiding problems such as tilting or jamming caused by uneven stress. In this regard, the technical solution of this application maintains a stable gap between the protection door 6 and the support plate 12 through the supporting action of the elastic arms 67, thus solving the technical problem of the lateral sliding gap between the protection door and the support plate. Compared with the prior art, this application not only ensures the flexible movement of the protection door, but also through the symmetrical arrangement of the elastic arms, when the socket adapter is removed, both sides of the protection door are in a balanced supported state, thus avoiding the problem of inconsistent heights of the neutral pole, live pole, and ground pole on it. Therefore, the technical solution of this application enhances the flexibility of the protection door movement while further enhancing its stability and reliability.

[0043] Furthermore, the ground pole 63 is located in the middle of the protection door 6, and the neutral pole 61 and the live pole 62 are arranged on both sides. Hooks 68 are provided at the lower ends of the neutral pole 61 and the live pole 62. When a single - side pole is pressed down, the hook 68 is engaged with the base socket 42 of the support plate 12 to limit the lateral movement of the protection door 6. When both - side poles are pressed down simultaneously, the protection door 6 and the support plate 12 move downward synchronously and are guided to move laterally through the guide rail 71. Specifically, the design of the hook 68 enables the lateral movement of the protection door 6 to be restricted when a single - side pole is pressed down, thus ensuring the functionality of the protection door 6. The shape and size of the hook 68 can be adjusted according to actual needs to ensure that it can be effectively engaged with the base socket 42. In addition, the path of the guide rail 71 is configured to guide the protection door 6 to move downward and laterally synchronously when both - side poles are pressed down, thus achieving the flexible movement and accurate positioning of the protection door 6. The material and structure of the guide rail 71 can also be optimized according to the actual application scenario to improve its durability and guiding accuracy.

[0044] Accordingly, in the present application, the ground wire convex post 63 is located in the middle of the protection door 6, the neutral wire convex post 61 and the live wire convex post 62 are arranged on both sides, and hooks 68 are provided at the lower ends of the neutral wire convex post 61 and the live wire convex post 62, solving the problem that the lateral movement of the protection door 6 is restricted when a single-sided convex post is pressed down. When a single-sided convex post is pressed down, the hook 68 is snapped into the base socket 42 of the support plate 12, restricting the lateral movement of the protection door 6 and ensuring the functionality of the protection door 6. Only when the convex posts on both sides are pressed down simultaneously, the protection door 6 and the support plate 12 move downward synchronously and the lateral movement is guided by the guiding slide rail 71, realizing the flexible movement and accurate positioning of the protection door 6. This technical solution effectively solves the movement problem of the protection door 6 when the single-sided and double-sided convex posts are pressed down through the cooperation of the hook 68 and the guiding slide rail 71, improving the safety and reliability of the power-taking track.
