Description

Technical Field

[0001] The utility model belongs to the field of power socket structure design, and in particular relates to a track socket with a fool-proof structure. Background Art

[0002] Track sockets are a new type of power outlet featuring a metal rail that can be mounted on a wall or floor, providing both power and data transmission. This design makes the outlet more flexible and convenient, allowing users to connect the power plug anywhere they choose, without being restricted to a fixed installation location. Track sockets are commonly used in commercial spaces, offices, exhibition halls, and other locations requiring flexible wiring. They can meet diverse power needs and improve safety and convenience.

[0003] To improve the safety of track sockets, they are typically equipped with a protective door. This door normally shields the power socket on the front of the socket, preventing foreign objects from entering and preventing electric shock accidents. However, current track socket protective doors generally lack a foolproofing feature. The power supply unit on the adapter can be pushed open and plugged into the power socket in both forward and reverse directions (only forward insertion will work properly). This lack of clear identification can lead to users inserting the adapter in the wrong direction, impacting the user experience. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0031] The track socket structure provided by the embodiment of the utility model is as follows Figures 1 to 9 As shown, it includes a socket body 1 and an adapter 2; the socket body 1 is provided with a power socket 11 on the front side, and a protective door 3 can be slidably installed at the power socket 11. Under normal circumstances, the protective door 3 blocks the power socket 11 under the action of the elastic member 4; the lower end of the adapter 2 has a power extraction part 21 suitable for inserting into the power extraction hole 11. During normal use, the power extraction part 21 of the adapter 2 is inserted into the power extraction hole 11. During the insertion process, the power extraction part 21 pushes the protective door 3 to slide open. After the power extraction part 21 is pulled out, the protective door 3 slides back to its original position under the elastic force of the elastic member 4.

[0032] See Figures 1 to 3 As shown, in order to prevent the adapter 2 from being inserted in the wrong direction when in use, a stopper 31 is provided on the protective door 3, a stopper 22 is provided on one side of the lower end of the power taking part 21, and an inclined guide 23 is provided on the other side. The power taking part 21 is inserted in a specific direction (such as Figure 4When the power taking part 21 is inserted into the power taking socket 11 in a non-specific direction (such as Figure 5 When the power outlet 11 is inserted (in the direction shown), the first stopper 31 and the second stopper 22 form a stop, preventing the power outlet 21 from pushing open the protective door 3, so that the power outlet 21 can be normally inserted into the power outlet 11 to draw power. This arrangement ensures that the user can only push open the protective door 3 in the correct direction when inserting the adapter, thereby avoiding unnecessary errors and potential risks. This design not only prevents improper use, but also ensures the stability and reliability of the product, providing users with a safer and more convenient user experience. Specifically, the cooperation between the power supply part 21 of the adapter 2 and the power supply socket 11 utilizes the relative position relationship between the stop part 1 31 and the stop part 2 22; when the adapter is inserted in the correct direction (i.e., a specific direction), the inclined guide part 23 allows the power supply part 21 to pass through the stop part 1 31 smoothly, and then the power supply part 21 pushes the protective door 3 to open; and when the direction of the adapter is incorrect (i.e., a non-specific direction), the stop part 1 31 and the stop part 2 22 conflict with each other, making it impossible for the power supply part 21 to open the protective door 3, thereby effectively preventing the occurrence of incorrect insertion; using the protective door 3 to prevent mistakes can fundamentally solve the problem of preventing wrong insertion, and the anti-mistake effect is significant.

[0033] like Figure 3 As shown, the protection doors 3 are provided on both sides of the power socket 11. Under normal circumstances, the protection doors 3 arranged on both sides of the power socket 11 are close to each other under the elastic force of the elastic member 4, thereby blocking the power socket 11. When the power taking part 21 is inserted into the power socket 11, thrusts in opposite directions can be applied to the protection doors 3 on both sides, so that the protection doors 3 slide open. Furthermore, the protection door 3 has a stop edge 32 extending obliquely toward the inside of the socket body 1 at one end close to the power socket 11, and the stop edges 32 on the protection doors 3 on both sides are arranged in a V shape. The stop portion 31 is provided on the protective door 3 on one side of the power outlet 11. When installing the adapter 2 on the socket body 1, the inclined guide portion 23 on one side of the lower end of the power outlet 21 is aligned with the stop portion 31 on the protective door 3 on the corresponding side so that the power outlet 21 can be inserted into the power outlet 11. During the insertion process of the power outlet 21, a lateral thrust is applied to the stop edge 32, thereby allowing the protective door 3 to open smoothly, thereby improving convenience and durability. In actual operation, the protective door 3 can also be installed on one side of the power outlet 11.

[0034] See Figure 3As shown, the first stopper 31 is a blocking surface provided above the blocking edge 32. The blocking surface faces upward and is normally exposed above the power outlet 11 and close to the edge of the power outlet 11. When the power supply unit 21 is inserted in a non-specific direction, the second stopper 22 directly contacts the blocking surface, thereby effectively blocking the power supply unit 21 and ensuring the foolproof effect of the protective door 3. When the power supply unit 21 is inserted in a specific direction, the inclined guide 23 avoids the blocking surface and directly contacts the inclined surface of the blocking edge 32, thereby pushing the protective door 3 open. The specific blocking surface can be a flat surface, a concave surface, or a stepped surface.

[0035] like Figures 4 to 6 As shown, the inclined guide portion 23 is a slope structure provided on the side of the lower end of the power taking portion 21. Such a setting can avoid the obstruction of the stop portion 31 through the slope structure when the power taking portion 21 is inserted into the power taking socket 11, and is suitable for generating a lateral thrust on the corresponding protective door 3 during the insertion process to enable the protective door 3 to open smoothly.

[0036] like Figure 9 As shown, the second stopper 22 is a boss structure provided at the lower end of the power taking part 21 , and the boss structure extends along the length direction of the power taking part 21 .

[0037] It is preferred that the sliding direction (ie, the opening and closing direction) of the protection door 3 is perpendicular to the direction in which the power extraction portion 21 is inserted into the power extraction socket 11 , so that the protection door 3 has a stable structure and is easy to install.

[0038] In some embodiments, as Figure 7 As shown, a mounting bracket 13 arranged along the length direction of the power socket 11 is installed in the socket body 1, and a plurality of independent protective doors 3 are provided on the mounting bracket 13 along its length direction. The elastic member 4 is arranged between each protective door 3 and the mounting bracket 13. Since a plurality of independent protective doors 3 are provided, after the power taking part 21 is inserted into the power taking socket 11, only the protective doors 3 at the corresponding parts slide to open, and the other protective doors 3 are still in a closed state. Therefore, the closed protective doors can form a stop and limit effect on the power taking part 21 to prevent the adapter from sliding; and the mounting bracket 13 provides effective support for the installation of the protective door 3, and the protective door 3 and the elastic member 4 can remain stable during use and are not prone to displacement or loosening; the mounting bracket 13 makes the installation process of the protective door 3 and the elastic member 4 easier, and they can be quickly fixed in the appropriate position, thereby improving production efficiency.

[0039] Exemplarily, the elastic member 4 can be a torsion spring, which can be set to an M shape, with its two ends bent to form parallel limiting arms 41, and corresponding limiting slots are set on the inner side of the protective door 3 and the mounting frame 13. The installation of the torsion spring is achieved by engaging the limiting arms 41 with the corresponding limiting slots. In order to adapt to the installation of the elastic member 4 and ensure the effectiveness of the elastic force, an upward depression can be set on the bottom surface of the protective door 3 to accommodate the elastic member 4. In actual operation, the elastic member 4 can also be set to other forms of spring members.

[0040] Furthermore, Figure 7 and Figure 8 As shown, in order to better limit the protection door 3, a limiting slide groove 131 is provided on the mounting frame 13 corresponding to each protection door 3, and the protection door can be slidably installed in the limiting slide groove 131. Limiting sliders 33 are provided on both sides of the protection door 3. The end of the limiting slide groove 131 close to the power socket 11 is open and stop blocks 132 are provided on both sides of the opening. The stop blocks 132 form a stop limit for the limiting slider 33 to prevent the protection door 3 from slipping out of the limiting slide groove 131, and the limiting slide groove 131 can guide and limit the protection door 3, so that the protection door 3 moves smoothly.

[0041] In some embodiments, since the socket body 1 of some track sockets is relatively long, if the mounting frame 13 is too long, it will be inconvenient to operate during assembly and the mounting frame 13 will be easily broken. At least two mounting frames 13 spliced ​​along its length are provided inside the socket body 1. In this way, the length of each mounting frame 13 can be shortened, and multiple mounting frames 13 can be sequentially installed into the socket body 1 in the manner of building blocks to facilitate assembly. Furthermore, at least two protective doors 3 are provided on each mounting frame 13. In this way, adjacent protective doors 3 are not affected, so as to better adapt to the installation of the adapter at different positions on the socket body.

[0042] Further, combined Figures 4 to 6 and Figure 9 As shown, in order to enhance the foolproof function of the track socket and to ensure that the track socket still has an effective foolproof function when the protective door 3 is damaged, the socket body 1 is provided with an foolproof boss 12, and the lower end of the power-taking part 21 is provided with a side of the inclined guide 23 provided with an avoidance recess 24. Specifically, the inclined guide 23 is provided at the edge of the avoidance recess 24. When the power-taking part 21 is inserted into the power-taking socket 11 in a specific direction, it avoids the foolproof boss 12 through the avoidance recess 24 (see Figure 6 As shown in the state), when the power taking part 21 is inserted into the power taking socket 11 in a non-specific direction, the stop part 22 and the anti-mistake boss 12 form a stop, so that the power taking part 21 can be inserted into the power taking socket 11 but cannot be inserted into place, thus achieving the anti-mistake purpose.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
