[0028] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0029] The embodiment of the present application provides a four-pole DC plug, which can solve the problem of the DC plug falling off from the socket in the related art.
[0030] See also Figures 1 to 4 , a four-pole DC plug comprising:
[0031] A plug end 1, with a mounting ring 2 connected to the plug end 1;
[0032] The limiting structure 3 includes:
[0033] - baffle 31, which is provided with a plurality of limiting holes 32;
[0034] - Several limiting members 33, which are connected to the mounting ring 2, match the limiting holes 32, and can move closely against the baffle 31;
[0035] The limiting member 33 has a disengaged position. When the limiting member 33 is in the disengaged position, the limiting member 33 can pass through the baffle 31 through the limiting hole 32.
[0036] The limiting structure 3 also includes a mounting plate 34;
[0037] The mounting plate 34 is connected to the baffle 31;
[0038] In this embodiment, the plug end 1 can be inserted into the socket, and the mounting ring 2 is a cylindrical structure. The mounting ring 2 is fixedly connected to one end of the plug end 1, and the size of the mounting ring 2 is larger than the size of the plug end 1, so that after the plug end 1 is inserted into the socket of the socket, the mounting ring 2 is tightly attached to the outer baffle 31 of the socket socket and installed on the edge of the socket socket. The baffle 31 is connected to the socket through the mounting plate 34. The surface of the mounting plate 34 facing the socket is affixed with foam double-sided tape, and the mounting plate 34 is fixed to the socket through the foam double-sided tape, so that the present application can be combined with the original device without changing the structure of the original device. Figure 2 As shown, the limiting hole 32 is a square hole, and the limiting hole 32 is opened from the inner edge to the outer edge of the baffle 31, so that when the plug end 1 is inserted into the socket, the limiting member 33 passes through the limiting hole 32 from one side of the baffle 31 to the other side of the baffle 31;
[0039] In the present application, the plug end 1 is cylindrical. During the process of inserting the plug end 1 into the socket, the limit member 33 will gradually pass through the limit hole 32. When the limit member 33 is completely moved from one side of the baffle 31 to the other side of the baffle 31, the plug end 1 is completely inserted into the socket. At this time, the rotating plug end 1 drives the limit member 33 to rotate. It should be pointed out that the mounting plate 34 needs to make the opposite sides of the limit member 33 close to the baffle 31 and the socket respectively, further limiting the position of the baffle 31, so that the plug end 1 cannot be pulled out of the socket.
[0040] The baffle 31 is a ring-shaped structure, and a plurality of limiting holes 32 are arranged around the edge of the baffle 31. The number of the plurality of limiting members 33 corresponds to the number of the plurality of limiting holes 32.
[0041] like Figure 2 As shown, the baffle 31 is set with the center of the socket as the center of the circle, so that when the plug 1 is inserted into the socket, the plug 1 will pass through the baffle 31. The baffle 31 will surround the plug 1, so that the different directions of the plug 1 can be restricted by multiple limit members 33, thereby restricting the plug 1 in multiple directions and improving the stability of the device;
[0042] Since any limiting member 33 can pass through any limiting hole 32, multiple limiting members 33 can facilitate the staff to a certain extent. The number of limiting holes 32 is four, and the number of limiting members 33 corresponds to the number of limiting holes 32, which is also four. The four limiting members 33 are arranged around the edge of the mounting ring 2 to achieve multi-directional restriction of the plug end 1.
[0043] It also includes a fixing ring 4 and a threaded ring 5, the threaded ring 5 is connected to the mounting ring 2, and the fixing ring 4 is threadedly connected to the threaded ring 5;
[0044] It also includes a plurality of fixing structures 6, the fixing structure 6 including a fixing block 61;
[0045] The fixing block 61 is provided on the fixing ring 4. The fixing block 61 matches the limiting hole 32 and can pass through the limiting hole 32.
[0046] like Figure 4 As shown, the threaded ring 5 is installed on the mounting ring 2, and the threaded ring 5 and the plug end 1 are installed on both sides of the mounting ring 2 respectively. The threaded ring 5 is hollow in the middle and open at both ends to facilitate the passage of wires. The outer surface of the threaded ring 5 is provided with threads. The fixing ring 4 is installed on the threaded ring 5 through threads, and a fixing block 61 is slidably connected to the fixing ring 4;
[0047] Since the fixing ring 4 is fixed to the threaded ring 5 by screwing, the fixing ring 4 rotates differently from the threaded ring 5 and the mounting ring 2. Therefore, after rotating the limiter 33, the fixing block 61 needs to be aligned with the limit hole 32.
[0048] After the plug 1 is inserted into the socket and the opposite sides of the limit member 33 are respectively close to the baffle 31 and the socket, the fixing block 61 is pushed to insert into the limit hole 32, and the fixing block 61 will not pass through the limit hole 32 completely, so that the fixing ring 4, the threaded ring 5, the mounting ring 2 and the limit member 33 cannot be pulled out and cannot be rotated, that is, they are stationary relative to the baffle 31 and the mounting plate 34. Since the baffle 31 and the mounting plate 34 are fixed to the socket, the plug 1 is located in the socket and cannot be pulled out through the further restriction of the fixing block 61 at this time, thereby preventing the limit member 33 from detaching from the limit hole 32 due to the rotation of the limit member 33, thereby causing the plug 1 to detach from the socket.
[0049] The fixing structure 6 further includes a spring 62;
[0050] The two ends of the spring 62 are connected to the fixing block 61 and the fixing ring 4 respectively;
[0051] In this embodiment, there are four fixing blocks 61, and the four fixing blocks 61 are evenly distributed on the fixing ring 4. A sliding groove for the fixing blocks 61 to slide is provided on the fixing ring 4. The number of the sliding grooves is four, and the four sliding grooves correspond to the four fixing blocks 61 one by one. A spring 62 is provided in each sliding groove. The spring 62 continuously outputs a force toward the socket to the fixing block 61. In order to facilitate the installation, the position of the fixing block 61 needs to be staggered with the limit member 33.
[0052] In the process of inserting the plug end 1 into the socket and the limiting member 33 into the limiting hole 32, the fixing block 61 will be close to the baffle 31 and the fixing block 61 moves relative to the fixing ring 4. At this time, the spring 62 contracts and the limiting member 33 rotates. When the fixing block 61 moves to the limiting hole 32, the fixing block 61 will automatically be inserted into the limiting hole 32 due to the action of the spring 62, thereby achieving the fixing effect.
[0053] A control ring 7 is connected to the fixing blocks 61, and the control ring 7 is slidably connected to the mounting ring 2. The control ring 7 is provided with a plurality of anti-slip grooves;
[0054] To subsequently pull the plug end 1 out of the socket, the four fixing blocks 61 need to be pulled out of the limit holes 32 at the same time, which is inconvenient to operate. Therefore, the four fixing blocks 61 are controlled simultaneously by the control ring 7. During operation, only the control ring 7 needs to be moved, thereby improving disassembly efficiency.
[0055] Here's how this application works:
[0056] When the present application is in use, it is first necessary to fix the mounting plate 34 and the baffle 31 with the center of the socket as the center, and then align the limiting member 33 with the limiting hole 32, and insert the plug end 1 into the socket. During the insertion process, the limiting member 33 moves from one side of the baffle 31 through the limiting hole 32 to the other side of the baffle, and the limiting member 33 is located on the other side and respectively clings to the baffle 31 and the socket. At the same time, the fixing member 61 moves relative to the fixing ring 4 close to the baffle 31, and then the plug end 1 and the mounting ring 2 are rotated so that the limiting member 33 and the fixing member 61 move close to the baffle 31. When the limiting member 33 is not aligned with the limiting hole, the plug end 1 cannot be pulled out of the socket. When the fixing member 61 moves to align with the limiting hole 32, the spring 62 will push the fixing member 61 into the limiting hole 32, so that the plug end 1 cannot rotate, thereby preventing the plug end 1 from being separated from the socket due to the rotation of the limiting member 33.
[0057] When the plug 1 needs to be pulled out of the socket, first pull the four fixing members 61 out of the limiting holes 32 through the control ring 7, and then rotate the plug 1 so that the limiting members 33 are aligned with the limiting holes 32. At this time, the plug 1 can be pulled out of the socket.
