Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this application.

[0040] According to one aspect of the present application, the present application provides a locking device 1 for a plug, see Figure 2-Figure 5 The locking device 1 of the plug includes a base 100 and a locking unit 200 .

[0041] According to an example embodiment, see Figure 2-Figure 5 The base 100 is fixed to one side of the socket device 3. Two opposite sides of the base 100 protrude upward to form a first T-shaped fixing wall 101 and a second T-shaped fixing wall 102. The middle portion of the first T-shaped fixing wall 101 extends inward to form a first extension portion 103, which is provided with a first fixing hole 105. The middle portion of the second T-shaped fixing wall 102 extends inward to form a second extension portion 104, which is provided with a second fixing hole 106. Both the first fixing hole 105 and the second fixing hole 106 can be provided with threads.

[0042] According to an example embodiment, see Figure 2-Figure 5 The locking unit 200 is provided on the base 100 to fix the plug 2 . The locking unit 200 includes a guide rod 210 , a fixing plate 220 and a rotation limiting mechanism 230 .

[0043] According to an example embodiment, see Figure 2-Figure 5 The guide rod 210 includes a first upper guide rod 211, a first lower guide rod 212, a second upper guide rod 213 and a second lower guide rod 214, and the first upper guide rod 211 and the first lower guide rod 212 are both provided with threads that match the threads of the first fixing hole 105, and the second upper guide rod 213 and the second lower guide rod 214 are both provided with threads that match the threads of the second fixing hole 106.

[0044] According to an example embodiment, see Figure 4-Figure 5One end of the first upper guide rod 211 is arranged on the side of the first T-shaped fixing wall 101 and fixed in the first fixing hole 105, and the other end is provided with a first upper limit block 215 for limiting. The first upper limit block 215 can be a nut.

[0045] See also Figure 4-Figure 5 The first lower guide rod 212 is arranged on the side of the first T-shaped fixing wall 101 and fixed in the first fixing hole 105. The other end is provided with a first lower limit block 216 for limiting. The first lower limit block 216 can be a nut.

[0046] See also Figure 4-Figure 5 One end of the second upper guide rod 213 is placed on the side of the second T-shaped fixed wall 102 and fixed in the second fixing hole 106, and the other end is provided with a second upper limit block 217 for limiting, and the second upper limit block 217 is at the same horizontal position as the first upper limit block 215, and the second upper limit block 217 can be a nut.

[0047] See also Figure 4-Figure 5 One end of the second lower guide rod 214 is arranged on the side of the second T-shaped fixing wall 102 and fixed in the second fixing hole 106, and the other end is provided with a second lower limit block 218 for limiting, and the second lower limit block 218 and the first lower limit block 216 are at the same horizontal position, and the second lower limit block 218 can be a nut.

[0048] According to an example embodiment, see Figure 4 The fixed plate 220 includes an upper fixed plate 221 and a lower fixed plate 222. The two ends of the upper fixed plate 221 are slidably connected to the first upper guide rod 211 and the second upper guide rod 213 respectively so that they can move along the first upper guide rod 211 and the second upper guide rod 213. The upper fixed plate 221 can slide from the first upper limit block 215 (the second upper limit block 217) to the first extension portion 103 (the second extension portion 104).

[0049] The two ends of the lower fixed plate 222 are slidably connected to the first lower guide rod 212 and the second lower guide rod 214 respectively so as to be able to move along the first upper guide rod 211 and the second upper guide rod 213. The lower fixed plate 222 can slide from the first lower limit block 216 (second lower limit block 218) to the first extension portion 103 (second extension portion 104).

[0050] According to an example embodiment, see Figure 4-Figure 5The rotation limiting mechanism 230 includes an upper rotation limiting mechanism 231 and a lower rotation limiting mechanism 232. The upper rotation limiting mechanism 231 is fixedly arranged on the base 100 and is located on the upper side of the upper fixed plate 221. The lower end of the upper rotation limiting mechanism 231 is in contact with the upper fixed plate 221, so that the upper fixed plate 221 presses the plug as the upper rotation limiting mechanism 231 rotates to the limited position. For example, the upper fixed plate slides from the first upper limit block 215 (the second upper limit block 217) to the upper end of the first extension portion 103 (the second extension portion 104) as the upper rotation limiting mechanism 231 rotates clockwise, thereby pressing the plug 2.

[0051] See also Figure 4-Figure 5 The lower rotation limit mechanism 232 is fixedly provided on the base 100 and is located on the lower side of the lower fixed plate 222. The upper end of the lower rotation limit mechanism 232 is in contact with the lower fixed plate 222, so that the lower fixed plate 222 presses the plug as the lower rotation limit mechanism 232 rotates to the limit position. For example, the lower fixed plate slides from the first lower limit block 216 (the second lower limit block 218) to the lower end of the first extension portion 103 (the second extension portion 104) as the lower rotation limit mechanism 232 rotates counterclockwise, thereby pressing the plug 2.

[0052] According to the exemplary embodiment, the upper fixed member slides from the upper end of the first extension portion 103 (the second extension portion 104) to the first upper limit block 215 (the second upper limit block 217) as the upper rotation limit mechanism 231 rotates counterclockwise, and the lower fixed member slides from the lower end of the first extension portion 103 (the second extension portion 104) to the first lower limit block 216 (the second lower limit block 218) as the lower rotation limit mechanism 232 rotates clockwise, and the upper fixed plate 221 and the lower fixed plate 222 release the plug 2 so that the plug 2 can be unplugged.

[0053] Through the above embodiment, the rotation of the rotation limit mechanism causes the fixing plate to press against the plug, thereby stably locking the plug. Simultaneously, as the rotation limit mechanism rotates, the fixing plate releases the plug, thereby quickly releasing the plug. The plug locking device has a simple structure and is easy to operate.

[0054] Alternatively, see Figure 2-Figure 4 The locking unit 200 further includes a first elastic member 240 , into which the guide rod 210 is inserted, and is disposed between the first fixing hole 105 and the fixing plate 220 , or between the second fixing hole 106 and the fixing plate 220 .

[0055] Exemplarily, the first elastic member 240 can be a spring. For example, the locking unit 200 includes four first elastic members 240, and the four first elastic members 240 are respectively inserted into the first upper guide rod 211, the first lower guide rod 212, the second upper guide rod 213 and the second lower guide rod 214, so that the upper fixing plate 221 and the lower fixing plate 222 smoothly compress the four first elastic members 240 in the process of tightening the plug 2. In the process of loosening the plug 2, the upper fixing plate 221 and the lower fixing plate 222 release the four first elastic members 240, converting the elastic potential energy into mechanical energy, assisting the upper fixing plate 221 to slide to the first upper limit block 215 (second upper limit block 217) and the lower fixing plate 222 to slide to the first lower limit block 216 (second lower limit block 218).

[0056] Alternatively, see Figure 2-Figure 3 The locking device 1 of the plug also includes a connecting plate 300, which is arranged on one side of the socket device 3. Four through holes are opened on the connecting plate 300, and four screws pass through the four through holes and are fastened to the screw holes of the socket device 3, so that the connecting plate 300 can be fixed on the socket device 3, and the base 100 can be fixed on the connecting plate 300 by the four screws.

[0057] Alternatively, see Figure 5 The base 100 includes a third upper fixing hole 107, a first upper stopping hole 108, a second upper stopping hole 109, a third lower fixing hole 110, a first lower stopping hole 111, and a second lower stopping hole 112. The third upper fixing hole 107, the first upper stopping hole 108, and the second upper stopping hole 109 are arranged at the upper end of the base 100, and the third lower fixing hole 110, the first lower stopping hole 111, and the second lower stopping hole 112 are arranged at the lower end of the base 100.

[0058] According to an example embodiment, the upper positioning structure includes an upper rotation shaft 2311 , an upper rotation column 2312 , a second upper elastic member 2313 , and an upper stopping pin 2314 .

[0059] See also Figure 4-Figure 5One end of the upper rotating shaft 2311 is fixed in the third upper fixing hole 107, and the other end is provided with a limit block for limiting. The lower end of the upper rotating column 2312 contacts the upper fixing plate 221. The interior of the upper rotating column 2312 is provided with a first upper through hole 2316, and the first upper through hole 2316 is coaxial with the upper rotating shaft 2311. The second upper elastic member 2313 is for the upper rotating shaft 2311 to be inserted. One end of the second upper elastic member is connected to the other end of the upper rotating shaft 2311, that is, connected to the limit block of the upper rotating shaft 2311, and the other end is connected to one end of the upper rotating column 2312, so that the upper rotating column 2312 slides elastically on the upper rotating shaft 2311. The upper stop pin 2314 is fixed to the other end of the upper rotating column 2312, and the upper stop pin 2314 is inserted into the first upper stop hole 108 or the second upper stop hole 109. For example, the first upper stop hole 108 may be a loosening stop hole, and the second upper stop hole 109 may be a locking stop hole.

[0060] Exemplarily, the second upper elastic member 2313 can be a spring, the upper rotating column 2312 can be a cam structure, the position of the second upper stop hole 109 (locking stop hole) corresponds to the longest stroke of the upper rotating column 2312, and the position of the first upper stop hole 108 (loosening stop hole) corresponds to the shortest stroke of the upper rotating column 2312.

[0061] According to an example embodiment, the lower limiting structure includes a lower rotation shaft 2321 , a lower rotation column 2322 , a second lower elastic member 2323 , and a lower stopping pin 2324 .

[0062] See also Figure 4-Figure 5 One end of the lower rotating shaft 2321 is fixed in the third lower fixing hole 110. A limiting block is provided at the other end for limiting the position. The upper end of the lower rotating column 2322 contacts the lower fixing plate 222. A first lower through hole 2326 is provided inside the lower rotating column 2322. The first lower through hole 2326 is coaxial with the lower rotating shaft 2321. The second lower elastic member 2323 is provided for the lower rotating shaft 2321 to be inserted. One end of the second lower elastic member 2323 is connected to the other end of the lower rotating shaft 2321, that is, connected to the limiting block of the lower rotating shaft 2321, and the other end is connected to one end of the lower rotating column 2322, so that the lower rotating shaft 2321 slides elastically on the lower rotating shaft 2321. The lower stop pin 2324 is fixed to the other end of the lower rotating column 2322. The lower stop pin 2324 is inserted into the first lower stop hole 111 or the second lower stop hole 112. For example, the first lower stopping hole 111 may be a loosening stopping hole, and the second lower stopping hole 112 may be a locking stopping hole.

[0063] Exemplarily, the second lower elastic member 2323 can be a spring, the lower rotating column 2322 can be a cam structure, the position of the second lower stop hole 112 (locking stop hole) corresponds to the longest stroke of the lower rotating column 2322, and the position of the first lower stop hole 111 (loosening stop hole) corresponds to the shortest stroke of the lower rotating column 2322.

[0064] According to an exemplary embodiment, after the plug 2 is inserted into the socket, the process of rotating the limiting mechanism 230 to press the plug 2 is as follows:

[0065] Pull the upper rotating shaft 2311 outward to disengage the upper stop pin 2314 of the upper rotating column 2312 from the first upper stop hole 108 of the base 100 (loosen the stop hole), and the second upper elastic member 2313 is compressed. Rotate the upper rotating shaft 2311 clockwise, and the upper rotating column 2312 pushes the upper fixed plate 221 to slide downward. The first elastic member 240 is compressed until the upper stop pin 2314 of the upper rotating column 2312 is inserted into the second upper stop hole 109 (lock the stop hole). The second upper elastic member 2313 is released, and the upper fixed plate 221 stops at this time.

[0066] Pulling the lower rotating column 2322 outward disengages the lower stop pin 2324 of the lower rotating column 2322 from the first lower stop hole 111 of the base 100 (loosening the stop hole), compressing the second lower elastic member 2323. Rotating the lower rotating column 2322 counterclockwise pushes the lower fixing plate 222 upward, compressing the second lower elastic member 2323 until the lower stop pin 2324 of the lower rotating column 2322 is inserted into the second lower stop hole 112 of the base 100 (locking the stop hole). The second lower elastic member 2323 is released, and the lower fixing plate 222 stops. This allows the upper fixing plate 221 and the lower fixing plate 222 to completely lock the plug 2.

[0067] According to an exemplary embodiment, the process of rotating the limiting mechanism 230 to release the plug 2 is as follows:

[0068] Pull the upper rotating shaft 2311 outward to disengage the upper stop pin 2314 of the upper rotating column 2312 from the second upper stop hole 109 (locking stop hole) of the base 100, and the second upper elastic member 2313 is compressed. Rotate the upper rotating shaft 2311 counterclockwise, and the position of the upper rotating shaft 2311 transitions from a long stroke to a short stroke. The first elastic member 240 is released, pushing the upper fixed plate 221 to move upward until the upper stop pin 2314 of the upper rotating column 2312 is inserted into the first upper stop hole 108 (loosening stop hole) of the base 100. The second upper elastic member 2313 is released, and the upper fixed plate 221 stops at this time.

[0069] Pulling the lower rotating column 2322 outward disengages the lower stop pin 2324 of the lower rotating column 2322 from the second lower stop hole 112 (locking stop hole) of the base 100, compressing the second lower elastic member 2323. Rotating the lower rotating column 2322 clockwise transitions the position of the lower rotating column 2322 from the long stroke to the short stroke, releasing the second lower elastic member 2323 and pushing the lower fixed plate 222 downward until the lower stop pin 2324 of the lower rotating column 2322 is inserted into the first lower stop hole 111 (loosening stop hole) of the base 100. The second lower elastic member 2323 then releases, stopping the lower fixed plate 222. This completely disengages the upper and lower fixed plates 221 and 222 from the plug 2, allowing the plug 2 to be removed.

[0070] Through the above-mentioned embodiment, the cam structure can achieve accurate and reliable travel of the upper rotating column 2312 and the lower rotating column 2322, thereby enhancing the locking effect of the upper fixing plate 221 and the lower fixing plate 222.

[0071] Optionally, the upper limit mechanism further includes an upper toggle handle 2315, which is fixed to the upper rotating column 2312 so that the operator can more conveniently rotate the upper rotating column 2312. The lower limit mechanism further includes a lower toggle handle 2325, which is fixed to the lower rotating column 2322 so that the operator can more conveniently rotate the lower rotating column 2322.

[0072] Optionally, the socket device may be an electrical device such as an uninterruptible power supply, and the locking device 1 of the plug may be applied to plugs of electrical devices such as a wall plug and an uninterruptible power supply.

[0073] According to one aspect of the present application, the present application provides a plug, which includes the locking device of the plug described above.

[0074] Finally, it should be noted that the above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions of the aforementioned embodiments or replace some of the technical features therein with equivalents.
