[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides an anti-electric shock connector for a pipeline system, such as Figure 1 、 Figure 2 and Figure 3 As shown, the anti-electric shock connector includes a female plug 1, a male plug 2 movably mounted on the female plug 1, a first connection end 3 fixedly mounted on the side surface of the female plug 1, a second connection end 4 fixedly mounted on the side surface of the male plug 2, a plug ring 5 fixedly mounted on one side of the second connection end 4, and a clamping block 6 fixedly mounted on the inner wall of the plug ring 5. A slot 7 adapted to the plug ring 5 is provided on the first connection end 3, and an L-shaped clamping groove 8 is provided on the first connection end 3.

[0027] When the first and second connecting ends 3 and 4 of the anti-electric shock connector are both circular rings, when using the anti-electric shock connector, the female plug 1 and the male plug 2 need to be docked first. When docking, the plug ring 5 on the second connecting end 4 and the card block 6 need to be aligned with the slot 7 and the L-shaped card slot 8 on the first connecting end 3. During the docking process, the plug ring 5 and the card block 6 will be inserted into the inside of the slot 7 and the L-shaped card slot 8 respectively. The L-shaped card slot 8 is L-shaped as a whole. When the card block 6 conflicts with the inner wall of the L-shaped card slot 8, it is necessary to rotate the female plug 1 or the male plug 2 so that the card block 6 continues to move a distance inside the L-shaped card slot 8 until the card block 6 conflicts with the inner wall of the L-shaped card slot 8 for the second time. At this time, the inner wall of the L-shaped card slot 8 will fix the card block 6, thereby completing the docking of the female plug 1 and the male plug 2. When separating the female plug 1 and the male plug 2, it is only necessary to rotate them in the opposite direction and pull one of them to separate the female plug 1 and the male plug 2.

[0028] Furthermore, in order to improve the firmness of the female plug 1 and the male plug 2 when they are connected together, as shown in FIG. Figure 2 、 Figure 5 and Figure 6 As shown, a fixed shell 11 is fixedly connected to the first connecting end 3, and a fixed column 12 is movably connected inside the fixed shell 11. The fixed column 12 passes through the fixed shell 11, and one end of the fixed column 12 is rotatably connected to an adjustment handle 14. One side of the adjustment handle 14 is in contact with the side of the fixed shell 11 away from the first connecting end 3.

[0029] A through hole 16 is provided on the first connecting end 3 , and the end of the fixing column 12 away from the adjusting handle 14 is movably connected inside the through hole 16 . The through hole 16 is connected to the slot 7 , and a socket 15 adapted to the fixing column 12 is provided on the side surface of the insert ring 5 .

[0030] The adjusting handle 14 can be rotated ninety degrees on the fixed shell 11. When the staff bends the adjusting handle 14, the adjusting handle 14 can drive the fixed column 12 connected thereto to move. The fixed column 12 will present two states under the influence of the adjusting handle 14. The first state is that the fixed column 12 extends through the through hole 16 to the inside of the slot 7, and the second state is that the fixed column 12 is retracted inside the fixed shell 11 and the through hole 16.

[0031] When the female plug 1 and the male plug 2 are connected, the first step is to turn the adjusting handle 14 so that the fixing post 12 is retracted inside the fixing shell 11 and the through hole 16, and then the plug ring 5 on the second connecting end 4 is aligned with the card block 6 in the slot 7 and the L-shaped card slot 8 on the first connecting end 3, and then the female plug 1 or the male plug 2 is moved so that the plug ring 5 and the card block 6 are respectively inserted into the slot 7 and the L-shaped card slot 8. When the card block 6 comes into conflict with the inner wall of the L-shaped card slot 8, the female plug 1 or the male plug 2 is rotated so that the card block 6 continues to move a certain distance inside the L-shaped card slot 8 until the card block 6 comes into conflict with the inner wall of the L-shaped card slot 8 for the second time. At this time, the insertion hole 15 on the plug ring 5 also just comes to the fixing post 12, and then by turning the adjusting handle 14, the adjusting handle 14 can drive the fixing post 12 to move, so that the fixing post 12 is inserted into the insertion hole 15, thereby improving the firmness of the female plug 1 and the male plug 2 being connected.

[0032] In order to improve the stability of the adjustment handle 14, Figure 2 、 Figure 5 and Figure 6 As shown, a second spring 13 is sleeved on the side surface of the fixing column 12 , one end of the second spring 13 is fixedly connected to the fixing column 12 , and the other end of the second spring 13 is fixedly connected to the inside of the fixing shell 11 .

[0033] The state of the fixed column 12 is controlled by the adjusting handle 14. Through the setting of the second spring 13, a thrust can be applied to the fixed column 12, thereby driving the adjusting handle 14 to be close to the fixed shell 11, effectively improving the stability of the adjusting handle 14, so that the adjusting handle 14 can better serve the fixed column 12.

[0034] It should be noted that in order to facilitate the staff to connect the female plug 1 and the male plug 2 together, as shown in FIG. Figure 2 、 Figure 4 and Figure 5 As shown, the slot 7 is movably connected to a push plate 9, the side surface of the push plate 9 slides against the inner wall of the slot 7, one side of the push plate 9 fits against the side of the insert ring 5 away from the second connection end 4, and the other side of the push plate 9 is fixedly connected to a first spring 10, and the end of the first spring 10 away from the push plate 9 is fixedly connected to the inner wall of the slot 7.

[0035] When docking the female plug 1 with the male plug 2, the plug ring 5 on the second connecting end 4 will be inserted into the slot 7 on the first connecting end 3. During this process, the plug ring 5 will come into contact with the push plate 9. As the plug ring 5 continues to move, the plug ring 5 will drive the push plate 9 to move inside the slot 7 and compress the first spring 10, and the first spring 10 will also apply a thrust to the push plate 9 at all times. When the block 6 and the inner wall of the L-shaped slot 8 produce a second conflict, it is necessary to bend the adjusting handle 14 so that the fixing column 12 is inserted into the socket 15. At this time, due to the presence of the first spring 10, the push plate 9 will be pushed close to the plug ring 5, thereby reducing the possibility of the plug ring 5 rotating and causing the socket 15 and the fixing column 12 to be misaligned, so as to ensure that the fixing column 12 can be smoothly inserted into the socket 15.

[0036] Furthermore, in order to reduce the possibility of external dust or water intrusion into the joint, Figure 3 、 Figure 4 and Figure 5 As shown, a rubber pad 17 is sleeved on the side surface of the insert ring 5 , and one side of the rubber pad 17 is fixedly connected to a side of the second connecting end 4 close to the insert ring 5 .

[0037] When the female plug 1 and the male plug 2 are docked, one end of the first connection end 3 will come into contact with the rubber pad 17. After the female plug 1 and the male plug 2 are docked, the first connection end 3 will squeeze the rubber pad 17 and, at the same time, cooperate with the second connection end 4 to form a sealed chamber, which can isolate the internal connection of the female plug 1 and the male plug 2 from the outside world, and can effectively reduce the possibility of external dust or water intrusion affecting the joint.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
