Description

Technical Field

[0001] The utility model relates to the technical field of power sockets, in particular to an adapter and a track socket. Background Art

[0002] The track socket is a new type of power socket, which usually includes a power track and an adapter that matches the power track. When in use, the power track is fixed on a desktop or wall, and the adapter is detachably connected to the power track and can be installed at different positions along the length of the power track. When installing the adapter, first extend the power-taking foot at the bottom of the adapter into the strip jack, and then rotate the adapter to connect the power-taking foot to the copper bar inside the power track to get power, and reversely rotate the adapter to separate the power-taking foot from the copper bar inside the power track to cut off the power. Compared with traditional fixed sockets, track sockets are more flexible to use. The existing track sockets also have the disadvantage that the adapter is easy to detach from the power track due to the lack of effective limit when it is powered off. Utility Model Content

[0003] In this regard, the utility model provides an adapter and a track socket using the adapter, which can effectively prevent the adapter from easily leaving the power track when the power is off by optimizing the structure.

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

[0005] In a first aspect, the utility model provides an adapter, including a housing, a rotating disk and a power supply unit;

[0006] The power taking part is fixed to the bottom of the shell, and is provided with a power taking foot;

[0007] The rotating disk is rotatably arranged on the shell, and is provided with a limiting plug extending from the bottom of the shell, and the limiting plug is provided with a receiving groove for receiving the power supply pin;

[0008] When the housing rotates relative to the rotating disk, the power-taking pin is driven to rotate between the first position, the second position and the third position. When the power-taking pin is in the first position, it is received in the receiving slot. When the power-taking pin is in the second position, it extends out of the receiving slot and forms an angle A with the limiting plug. When the power-taking pin is in the third position, it extends out of the receiving slot and forms an angle B with the limiting plug. The angle A is smaller than the angle B.

[0009] It also includes a locking component and an unlocking button installed on the shell. The turntable is provided with a first locking portion. When the power-collecting pin is in the second position, the locking component cooperates with the first locking portion to limit the power-collecting pin from rotating toward the first position.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] In a first aspect of the present embodiment, an adapter is provided in the present embodiment, such as Figures 2 to 8 As shown, it includes a shell 1, a turntable 2 and a power-taking part 3; in order to adapt to the installation of internal components, the shell 1 adopts a split assembly structure, which is formed by the upper shell 12 and the lower shell 13. The power-taking part 3 is fixed to the bottom of the shell 1 and is provided with a power-taking foot 31, and the power-taking foot 31 is connected to the socket 11 in the shell 1; the turntable 2 is rotatably arranged on the shell 1, and is provided with a limiting plug 21 extending from the bottom of the shell 1, and the limiting plug 21 is provided with a The receiving slot 22 of the power-taking pin 31; when the housing 1 rotates relative to the turntable 2, the power-taking pin 31 is driven to rotate between the first position, the second position and the third position. When the power-taking pin 31 is in the first position, it is accommodated in the receiving slot 22. When the power-taking pin 31 is in the second position, it extends out of the receiving slot 22 and forms an angle A with the limiting plug 21. When the power-taking pin 31 is in the third position, it extends out of the receiving slot 22 and forms an angle B with the limiting plug 21. The angle A is smaller than the angle B. For details, see Figures 6 to 8 As shown, illustratively, the angle B can be set to 80 degrees to 90 degrees, and the angle A can be set to 40 degrees to 50 degrees.

[0036] When installing the adapter on the power rail, first ensure that the power pin 31 is in the first position, that is, it is received in the receiving slot 22, then insert the limit plug 21 into the socket 71 on the power rail 7, and then rotate the housing 1 to make the power pin 31 pass the second position and then reach the third position. At this time, the power pin 31 is connected to the copper bar in the power rail 7 to draw power; when controlling the adapter to be powered off, the housing 1 is rotated in the opposite direction to drive the power pin 31 to rotate to the second position. At this time, the power pin 31 is separated from the copper bar 72, and the adapter is in a power-off state. However, since the power pin 31 is still extended out of the receiving slot 22, the adapter cannot be removed from the power rail. When the adapter needs to be completely removed from the power rail, the power pin 31 is rotated into the receiving slot 22 and then pulled out from the socket 71 to remove the adapter. In order to keep the power pin in the second position so that the adapter will not fall off the power rail 7 when the power is off, a locking member 4 and an unlocking button 5 are installed on the housing 1.

[0037] Specifically, a first locking portion 23 is provided on the turntable 2. When the power-collecting pin 31 is in the second position, the locking member 4 cooperates with the first locking portion 23 to limit the power-collecting pin 31 from rotating toward the first position. In this way, the power-collecting pin 31 can be prevented from rotating toward the first position, thereby preventing the adapter from falling off the power rail. When the unlocking button 5 is pressed by an external force, the locking member 4 controls the first locking portion 23 to be disengaged. In this way, the power-collecting pin 31 can be rotated toward the first position, thereby removing the adapter from the power rail. For the convenience of operation, a pressing handle 51 exposed from the shell 1 is provided at the outer end of the unlocking button 5. By applying pressure to the pressing handle 51, the unlocking button 5 is driven to move to control the locking member 4 to unlock.

[0038] In this embodiment, the unlocking button 5 is arranged on the side wall of the housing 1 . As a variation, in actual operation, the unlocking button 5 can also be arranged at other positions, such as on the top surface of the housing 1 .

[0039] In this embodiment, the unlocking button 5 is movably arranged on the housing 1 , a through hole for the pressing handle 51 to extend out is arranged on the housing 1 , and a cover plate 10 for limiting the position of the unlocking button 5 is fixed in the housing 1 .

[0040] In this embodiment, see Figure 4 and Figure 5As shown, the locking component 4 includes a locking block 41 and a first elastic member 42. The middle portion of the locking block 41 is pivotally connected to the housing 1 via a connecting shaft 410. One end of the locking block 41 is provided with a locking end 411 for cooperating with the first locking portion 23, and the other end is an unlocking end 412 corresponding to the unlocking button 5. In normal state, under the elastic force of the first elastic member 42, the locking end 411 maintains a tendency to move toward the direction of the turntable 2, and at the same time, the unlocking end 412 maintains a tendency to move toward the direction of the unlocking button 5, so that the locking end 411 and the first locking portion 23 are opposite to each other and the two can quickly form a match. When the unlocking button 5 is pressed by an external force, the unlocking end 412 is pressed, so that the locking end 411 moves away from the turntable 2.

[0041] In some embodiments, the first elastic member 42 is a torsion spring mounted on the connecting shaft 410 , one end of the torsion spring is connected to the housing, and the other end is connected to the locking block 41 ; as a variation, the first elastic member 42 may also be a compression spring.

[0042] In order to allow the unlocking button 5 to quickly move and reset after the pressure applied to the unlocking button 5 is removed, a second elastic member 6 is further provided in the present embodiment, and the second elastic member 6 provides a reset elastic force for the unlocking button 5. In actual operation, the second elastic member 6 may not be provided. In this case, the reset elastic force of the unlocking button 5 is provided by the first elastic member 42 in the locking component 4. Specifically, the elastic force provided by the first elastic member 42 to the locking block 41 is transmitted to the unlocking button 5 through the unlocking end 412, thereby resetting the unlocking button 5.

[0043] In a preferred solution, in order to facilitate the installation of the second elastic member 6, the second elastic member 6 adopts a helical compression spring, which is sleeved on the unlocking button 5, with one end abutting on the unlocking button 5 and the other end abutting on the stopper in the shell 1.

[0044] In some embodiments, a second locking portion 24 is provided on the turntable 2. When the power-collecting pin 31 is in the third position, the locking member 4 cooperates with the second locking portion 24 to limit the power-collecting pin 31 from rotating toward the second position. In this case, the power-collecting pin 31 can be locked to ensure that the power-collecting pin 31 remains connected to the copper bar in the power track, thereby ensuring the reliability of the electrical connection.

[0045] In some embodiments, the first locking portion 23 and the second locking portion 24 are steps formed on the edge of the turntable 2, and the locking end 4 of the locking block 41 abuts against the steps to achieve a stop limit to keep the power supply pin at a corresponding position.

[0046] In the second aspect, this embodiment provides a track socket, the structure of which is as follows: Figure 1As shown, it includes a power track 7 and the adapter described in any of the above embodiments, the power track 7 is provided with a socket 71 for inserting a limit plug 21, and a copper bar 72 is provided in the power track 7. During the insertion of the limit plug 21 into the socket 71, the power-taking pin 31 is in the first position, and the adapter can be installed and removed from the power track. After the limit plug 21 is inserted into the socket 71, the power-taking pin 31 is not connected to the copper bar 72 when the power-taking pin 31 is in the second position. At this time, the adapter is in a power-off state but cannot be removed from the power track. After the limit plug 21 is inserted into the socket 71, the power-taking pin 31 is connected to the copper bar 72 when the power-taking pin 31 is in the third position, and the adapter is in a power-taking state.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
