[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See also Figure 1-Figure 3 A transformer based on a quick-plug winding connection structure includes an oil tank 1, a winding 2 installed inside the oil tank 1 and provided with a lead 21, and several pipe sleeves 3 located above the oil tank 1 and fixedly connected to a conductive rod 31 inside. Several connecting mechanisms 4 arranged in a matrix are installed on the top of the oil tank 1, and a plug-in mechanism 5 that is fixedly connected to the bottom of the pipe sleeve 3 and is plugged into and matched with the connecting mechanism 4.

[0031] See also Figure 2 、 Figure 3 and Figure 8 The plug-in mechanism 5 includes a pressure cover 51 fixedly connected to the bottom of the pipe sleeve 3, and a plug 52 is fixedly connected to the bottom of the horizontal part of the pressure cover 51. Limiting grooves 521 are provided on the left and right sides of the plug 52. The left and right sides of the pressure cover 51 are hinged with a clamping plate 53. The bottom end of the pipe sleeve 3 extends to the bottom of the plug 52 and is fixedly connected to the connector 2 32.

[0032] See also Figure 2 、 Figure 3 and Figure 4 The connecting mechanism 4 includes a mounting base 41 fixedly mounted on the fuel tank 1 and having a socket 411 in the middle. The left and right sides of the mounting base 41 are fixedly connected with clamping blocks 412 that are engaged with the corresponding clamping plates 53. A wedge block 42 and a moving component 43 that are symmetrical on both sides for locking the plug 52 are slidably mounted inside the mounting base 41. A sealing ring 6 is also installed between the top of the mounting base 41 and the horizontal part of the pressure cover 51 for sealing.

[0033] See also Figure 2 、 Figure 3 and Figure 5 The bottom of the mounting seat 1 41 passes through the interior of the fuel tank 1 and is fixedly connected to the mounting seat 2 44. The top of the lead 21 extends to the interior of the mounting seat 2 44 and is fixedly connected to the connector 1 22 that is plugged into the connector 2 32. The interior of the mounting seat 2 44 is slidably installed with a wedge block 2 45 and a movable component 2 46 that are symmetrical on both sides for locking the connector 2 32.

[0034] See also Figures 1-8 When using it specifically, when installing the pipe sleeve 3, first press the top of the clamping plate 53 toward the pipe sleeve 3 to make the bottom end of the clamping plate 53 away from the plug 52, then align the plug 52 with the socket 411 and insert it into the socket 411. At this time, the second connector 32 at the bottom of the plug 52 will be inserted into the first connector 22. During the plugging process, the plug 52 and the second connector 32 respectively push the wedge block 1 42 and the wedge block 2 45 to move away from the center of the mounting seat 1 41. When the plug 52 is fully plugged into the socket 411, When the plug 52 is in the center, the wedge block 42 will be aligned with the limit groove 521, and the moving component 43 is used to push the wedge block 42 toward the center of the mounting seat 41, so that the wedge block 42 is inserted into the limit groove 521 to fix the plug 52 and prevent the plug 52 from loosening. At the same time, the moving component 2 46 is used to push the wedge block 2 45 toward the center of the mounting seat 2 44, so that the wedge block 2 45 is plugged and locked to the connector 2 32, thereby improving the firmness of the connection between the connector 2 32 and the connector 1 22.

[0035] After locking is completed, the horizontal portion of the pressure cover 51 is pressed tightly against the top of the mounting seat 41 , and the sealing ring 6 is used to seal the gap between the mounting seat 41 and the horizontal portion of the pressure cover 51 to prevent external impurities from entering the mounting seat 41 .

[0036] Then release the pressure on the top of the clamping plate 53, and then push the bottom of the clamping plate 53 toward the plug 52, so that the bottom of the clamping plate 53 is clamped together with the clamping block 412, thereby achieving secondary locking of the plug 52 and further improving the firmness of the installation of the pipe sleeve 3.

[0037] See also Figure 3 and Figure 7 The connector 1 22 is composed of two U-shaped terminals, and the connector 2 32 is in an inverted U shape. The two vertical sections of the connector 2 32 are respectively plugged into the corresponding terminals. The opposite sides of the two terminals are provided with a through hole 1 221. The two vertical sections of the connector 2 32 are provided with a through hole 2 321. The end of the wedge block 2 45 close to the center of the mounting seat 2 44 slides through the corresponding through hole 1 221.

[0038] See also Figure 3 、 Figure 7 and Figure 8 When in use, two terminals are set for connection. When one of the terminals has poor contact, the other terminal can still maintain an effective connection to avoid power outages. When the vertical section of the second connector 32 is fully inserted into the corresponding terminal, the through hole 1 221 will coincide with the through hole 2 321. At this time, the wedge block 25 can be inserted into the corresponding through hole 1 221 and the through hole 2 321. The wedge block 25 is used to lock the connector 1 22 and the connector 2 32 to prevent the connector 1 22 and the connector 2 32 from loosening, thereby ensuring the firmness of the connection between the connector 1 22 and the connector 2 32.

[0039] See also Figure 3 and Figure 7 The opposite sides of the two terminals are fixedly connected with wedge-shaped protrusions 222, and the bottom of the horizontal section of the second connector 32 is fixedly connected with a tightening block 322 located between the two vertical sections.

[0040] See also Figure 3 、 Figure 7 and Figure 8 During specific use, after the plug 52 is inserted into the socket 411, the two vertical sections of the second connector 32 are respectively inserted into the corresponding terminals, and the tightening block 322 is inserted between the left and right terminals. When the tightening block 322 contacts the inclined surface of the top of the wedge-shaped protrusion 222, the tightening block 322 is used to push the wedge-shaped protrusion 222 away from the center of the second mounting seat 44, so that the terminal clamps the second connector 32 to avoid poor contact.

[0041] See also Figure 3 and Figure 4 The moving component 43 includes a pushing block 431 that is slidably installed inside the mounting seat 41. The side of the pushing block 431 close to the center of the mounting seat 41 is fixedly connected to the corresponding wedge block 42, and a return spring 432 is fixedly connected between the side of the pushing block 431 away from the center of the mounting seat 41 and the inner wall of the mounting seat 41.

[0042] See also Figure 3 、 Figure 4 and Figure 8 When the plug 52 is fully inserted into the socket 411, the limit groove 521 is just aligned with the wedge block 42. At this time, the rebound force of the return spring 432 is used to push the pushing block 431 and the wedge block 42 to move toward the center of the mounting seat 41, so that the wedge block 42 is inserted into the corresponding limit groove 521, thereby locking the plug 52 and improving the firmness of the connection between the plug 52 and the mounting seat 41.

[0043] See also Figure 3 and Figure 5 The moving component 2 46 includes a pushing block 2 461 that is slidably installed left and right inside the mounting seat 1 41. The side of the pushing block 2 461 close to the center of the mounting seat 2 44 is fixedly connected to the corresponding wedge block 2 45 and contacts the corresponding terminal. The side of the pushing block 2 461 away from the center of the mounting seat 2 44 is fixedly connected to the inner wall of the connecting mechanism 4 with a reset spring 2 462.

[0044] See also Figure 3 、 Figure 5 and Figure 8 When the second terminal 32 is fully inserted into the corresponding terminal, the return spring 462 is used to push the pushing block 461 and the wedge block 45 to move toward the center of the mounting seat 44, so that the wedge block 45 locks the connector 1 22 and the connector 2 32 together to prevent the connector 1 22 and the connector 2 32 from loosening; at the same time, the pushing block 461 can also squeeze the outer wall of the terminal, so that the terminal and the vertical section of the connector 32 fit more closely, further avoiding poor contact.

[0045] See also Figure 3-Figure 5, the interior of the mounting seat 1 41 and the mounting seat 2 44 are also respectively installed with an unlocking component 1 47 and an unlocking component 2 48 for unlocking the wedge block 1 42 and the wedge block 2 45. The unlocking component 1 47 includes a movable rod 471 that is slidably installed up and down inside the mounting seat 1 41 and is symmetrically distributed on the left and right. The movable rod 471 is in an inverted L shape. Space is reserved on the mounting seat 1 41 for the movable rod 471 to move up and down, and a wedge-shaped groove 472 is provided on the pushing block 1 431 for the movable rod 471 to move through up and down. The vertical section of the movable rod 471 is fixedly connected to a wedge-shaped plug 473 on the side away from the center of the mounting seat 1 41. The wedge plug 473 is slidably engaged with the inclined surface of the corresponding wedge groove 472. A return spring three 474 is fixedly connected between the bottom of the horizontal section of the movable rod 471 and the inner wall of the mounting seat 1 41. The structure of the unlocking component 2 48 is the same as that of the unlocking component 1 47, and the movable rods 471 of the two are fixedly connected.

[0046] See also Figure 3-Figure 5 When the lock is unlocked, the movable rod 471 in the unlocking assembly 47 is pushed downward. At this time, the return spring 3 474 is compressed and contracted, and the movable rod 471 drives the wedge-shaped plug 473 to move downward. The wedge-shaped groove 472 cooperates with the wedge-shaped plug 473 to make the wedge-shaped plug 473 push the pushing block 1 431 to move away from the center of the mounting seat 1 41, and the pushing block 1 431 drives the wedge block 1 42 to move away from the center of the mounting seat 1 41, thereby releasing the lock of the wedge block 1 42 on the plug 52. Similarly, when the upper movable rod 471 moves downward, the lower movable rod 471 will move downward synchronously, releasing the lock of the wedge block 2 45 on the connector 1 22, and quickly releasing the lock of the plug 52 and the connector 2 32, thereby facilitating the rapid disassembly of the pipe sleeve 3.

[0047] When the plug-in mechanism 5 is completely separated from the connecting mechanism 4, the downward pressure on the unlocking component 47 is released, and the rebound force of the return spring 3 474 is used to push the movable rod 471 to move upward, and then the movable rod 471 drives the wedge-shaped plug 473 to move upward and reset. When the wedge plug 473 moves upward, the wedge plug 473 gradually releases the push on the pushing block 431. At this time, the rebound force of the return spring 1 432 is used to push the pushing block 1 431 and the wedge block 1 42 to move toward the center of the mounting seat 1 41, so that the pushing block 1 431 and the wedge block 1 42 are reset. Similarly, after the unlocking component 2 48 releases the push on the pushing block 2 461, the pushing block 2 461 and the wedge block 2 45 will be reset under the push of the return spring 2 462, which is convenient for the subsequent installation of the pipe sleeve 3.

[0048] See also Figure 3 、 Figure 4 and Figure 6, and also includes a linkage component 49, the linkage component 49 includes a sealing plate 491 that is slidably installed inside the mounting seat 41 up and down, and the sealing plate 491 is in a circular ring shape. The horizontal section of the movable rod 471 in the unlocking component 47 is fixedly connected to the inner wall of the sealing plate 491, and the outer ring wall of the sealing plate 491 is fixedly connected with push blocks 492 that are symmetrically distributed on the left and right. The push blocks 492 are slidably connected to the mounting seat 41 up and down, and the end thereof away from the center of the mounting seat 41 extends to the outside of the mounting seat 41.

[0049] See also Figure 3 、 Figure 4 and Figure 6 During specific use, the left and right movable rods 471 are connected together by the partition plate 491, and the partition plate 491 is driven to move downward by pushing the push block 492, which can simultaneously drive the left and right movable rods 471 to move downward, which is conducive to the synchronous unlocking of the wedge block 1 42 and the wedge block 2 45 on the left and right sides, and conveniently and quickly unlocking the plug 52 and the connector 2 32. At the same time, the partition plate 491 can also seal the space reserved for the upward and downward movement of the movable rod 471 on the mounting seat 1 41, thereby preventing external impurities from entering through the reserved space and avoiding adverse effects on the upward and downward movement of the movable rod 471.

[0050] See also Figure 3 、 Figure 8 and Figure 9 A rotating shaft 531 is rotatably installed at the hinge point of the clamping plate 53, and the rotating shaft 531 is fixedly connected to the top of the pressure cover 51. A torsion spring 532 is fixedly installed on the rotating shaft 531 for pushing the clamping plate 53 to rotate downward. Windows 511 are provided on the left and right sides of the pressure cover 51 for exposing the push block 492. A blocking bar 533 is also fixedly connected to the side of the clamping plate 53 close to the center of the pressure cover 51 for blocking and limiting the push block 492. The blocking bar 533 is located below the push block 492.

[0051] See also Figure 3 、 Figure 4 、 Figure 8 and Figure 9 When the locking plate 53 is in engagement with the clamping block 412, the locking plate 53 is locked against the outside of the window 511, and the locking plate 53 is used to block the push block 492, preventing the push block 492 from accidentally moving downward, thereby improving the security of locking the plug 52 and the second connector 32. At the same time, the blocking bar 533 can support the push block 492, preventing the push block 492 from moving up and down due to factors such as vibration and shaking, thereby further improving the security of locking the plug 52 and the second connector 32.
