[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides an inner frame assembly for a power plug, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. The inner frame assembly for the power plug includes a plug body 1, a storage groove 2 opened inside the plug body 1, an insertion rod 7 fixedly connected inside the storage groove 2, an inner frame plate 3 inserted inside the storage groove 2, a placement groove 4 opened inside the inner frame plate 3, an outer shell 5 fixedly connected inside the placement groove 4, a clamping mechanism arranged inside the outer shell 5 for clamping the insertion rod 7, and a release mechanism arranged inside the outer shell 5 for releasing the insertion rod 7.

[0025] The clamping mechanism includes an insertion cylinder 6 fixedly installed inside the outer shell 5, a fixed block 8 fixedly installed on the inner wall of the outer shell 5, a telescopic rod 9 fixedly installed on the fixed block 8, a first spring 10 sleeved on the telescopic rod 9, and an insertion block 11 fixedly installed at the movable end of the telescopic rod 9. The insertion rod 7 is movably connected inside the insertion cylinder 6.

[0026] The insertion block 11 is inserted into an annular groove on the side surface of the insertion rod 7 through a slot opened on the insertion block 11. One end of the first spring 10 is fixedly connected to one side of the insertion block 11, and the other end of the first spring 10 is fixedly connected to one side of the fixed block 8.

[0027] When the user uses the inner frame assembly of the power plug, manually align the inner frame plate 3 with the storage groove 2, and then press the inner frame plate 3 downward until the bottom of the inner frame plate 3 is connected to the bottom of the storage groove 2. During this process, the outer shell 5 inside the placement groove 4 moves along with it, so that the plug rod 7 is inserted into the inside of the socket cylinder 6. After the plug rod 7 touches the two plug blocks 11, since the surface of the plug block 11 in contact with the plug rod 7 is arc-shaped, the plug rod 7 will push the two plug blocks 11 outwards. The plug block 11 will squeeze the first spring 10, and the telescopic rod 9 will contract inward. Continue to press the inner frame plate 3, and the plug rod 7 will continue to move until the annular groove on the side surface of the plug rod 7 and the plug block 11 are at the same level. The plug rod 7 no longer squeezes the plug block 11. Through the elastic potential energy of the first spring 10, the plug block 11 is pushed inward, and the telescopic rod 9 will elongate until the two plug blocks 11 clamp the plug rod 7, thus firmly fixing the plug body 1 and the inner frame plate 3 together.

[0028] Furthermore, in order to facilitate the removal of the inner frame plate 3 from the inside of the plug body 1, as Figure 1 , Figure 3 and Figure 5 shown, the release mechanism includes a control block 14 fixedly installed on the plug block 11, a pressing block 15 slidably installed inside the outer shell 5, and a plurality of control rods 16 fixedly installed at the bottom of the pressing block 15.

[0029] The release mechanism further includes a support plate 13 slidably installed on the socket cylinder 6 and a second spring 12 sleeved on the side surface of the socket cylinder 6. The side surface of the control rod 16 is slidably attached to the side surface of the control block 14.

[0030] The bottom of the control rod 16 is fixedly connected to the top of the support plate 13. One end of the second spring 12 is fixedly connected to the bottom of the support plate 13, and the other end of the second spring 12 is fixedly connected to the inside of the outer shell 5.

[0031] When the user uses the inner frame assembly of the power plug and needs to remove the inner frame plate 3 from the inside of the plug body 1, by manually pressing the pressing block 15, the pressing block 15 can drive the control rod 16 to move downward. And the control rod 16 is trapezoidal, and the hypotenuse of the control rod 16 is adapted to the control block 14. Therefore, when the control rod 16 moves vertically, it can drive the control block 14 to move horizontally, and then the control block 14 drives the plug block 11 to contract, so that the plug rod 7 can be released.

[0032] Among them, after the inner frame plate 3 is taken out from the inside of the plug body 1, in order to enable the pressed pressing block 15 to reset itself, the bottom of the control rod 16 is fixedly connected to the top of the support plate 13, one end of the second spring 12 is fixedly connected to the bottom of the support plate 13, and the other end of the second spring 12 is fixedly connected to the top of the bottom plate 18. When the pressing block 15 is pressed down, the second spring 12 is contracted by driving the support plate 13 through the control rod 16. When the external force acting on the pressing block 15 is removed, the elastic potential energy of the second spring 12 is converted into kinetic energy, and then a restoring force for restoring the original state is generated. This force can effectively drive the control rod 16, together with the support plate 13 and the pressing block 15, to move along the direction of its initial position until the entire assembly returns to the original state without being acted upon by an external force. This process ensures that the pressing block 15 will not interfere with the normal operation of other components in the system due to residual displacement, thereby maintaining the stability and continuity of the entire mechanical structure and avoiding possible functional disorders caused by component misalignment.

[0033] Furthermore, in order to seal the placement groove 4, as Figure 1 、 Figure 2 and Figure 3 shown, pins 17 are fixedly connected to the top of the inner frame plate 3, and a rubber cover 18 for protecting the outer shell 5 is movably connected to the inner frame plate 3. The placement groove 4 penetrates through the inner frame plate 3.

[0034] When the user uses the inner frame assembly of the power plug, after inserting the inner frame plate 3 into the inside of the plug body 1, the placement groove 4 is sealed by inserting the rubber cover 18 into the placement groove 4 opened on the inner frame plate 3. This can not only prevent accidental contact with the pressing block 15 during use but also improve the aesthetics of the inner frame plate 3. The pins 17 are inserted into the socket for use.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
