[0010]This utility model discloses a high-pressure manifold quick connector with a multi-stage rotary interlocking structure. The locking limit block, unlocking limit block, and safety pin restrict the circumferential rotation of the female locking flange on the union female head. The high-pressure manifold is multi-locked by the male locking ring, female locking ring, and locking rod, facilitating unlocking and locking operations. Specifically, when locking the union male head and the union female head is required, ensure the female locking ring is in the unlocked position, and pass the safety pin through the female locking flange and the female head flange respectively. Then, align the locking rod with the locking hole on the end face of the male locking flange, and push the union female head forward so that the locking rod passes through the locking flange. Stop pushing when the end faces of the union male head and the union female head contact each other. At this point, the male locking flange does not restrict the front end of the female locking ring, and the front end of the female locking ring passes through the slotted surface on the male locking flange. After removing the cotter pin from the safety pin, pull out the safety pin. Rotate the female locking ring towards the locking limit block until the side of the female locking ring is flush against the locking limit block. Then, pass the safety pin through the female locking flange and the female flange, and install the cotter pin. At this point, the female locking ring also passes through the slotted surface of the locking rod. The locking rod and the male locking flange restrict the forward and backward movement of the female locking ring, and the female locking flange restricts the forward and backward movement of the male locking ring. At this point, the union male and female heads are locked. When it is necessary to unlock the union male and female heads, remove the cotter pin on the safety pin, pull out the safety pin, and rotate the female locking ring towards the unlocking limit block until the side of the female locking ring is pressed against the unlocking limit block. At this point, the female locking ring is disengaged from the slotted surface of the locking rod, and the locking rod and the male locking flange no longer restrict the forward and backward movement of the female locking ring, and the female locking flange no longer restricts the forward and backward movement of the male locking ring. Then, pass the safety pin through the female locking flange and the female flange, and install the cotter pin. At this point, pull the union female head outwards until the locking rod is completely disengaged from the male head locking flange. The union male head and the union female head are then unlocked. This solves the problems of cumbersome operation and inconvenient unlocking and locking of existing flange and bolt connections.

[0009] The male locking ring, the locking rod, the female locking ring, and the operating handle are all present in two forms.
[0010] This utility model discloses a high-pressure manifold quick connector with a multi-stage rotary interlocking structure. The locking limit block, unlocking limit block, and safety pin restrict the circumferential rotation of the female locking flange on the union female head. The high-pressure manifold is multi-locked by the male locking ring, female locking ring, and locking rod, facilitating unlocking and locking operations. Specifically, when locking the union male head and the union female head is required, ensure the female locking ring is in the unlocked position, and pass the safety pin through the female locking flange and the female head flange respectively. Then, align the locking rod with the locking hole on the end face of the male locking flange, and push the union female head forward so that the locking rod passes through the locking flange. Stop pushing when the end faces of the union male head and the union female head contact each other. At this point, the male locking flange does not restrict the front end of the female locking ring, and the front end of the female locking ring passes through the slotted surface on the male locking flange. After removing the cotter pin from the safety pin, pull out the safety pin. Rotate the female locking ring towards the locking limit block until the side of the female locking ring is flush against the locking limit block. Then, pass the safety pin through the female locking flange and the female flange, and install the cotter pin. At this point, the female locking ring also passes through the slotted surface of the locking rod. The locking rod and the male locking flange restrict the forward and backward movement of the female locking ring, and the female locking flange restricts the forward and backward movement of the male locking ring. At this point, the union male and female heads are locked. When it is necessary to unlock the union male and female heads, remove the cotter pin on the safety pin, pull out the safety pin, and rotate the female locking ring towards the unlocking limit block until the side of the female locking ring is pressed against the unlocking limit block. At this point, the female locking ring is disengaged from the slotted surface of the locking rod, and the locking rod and the male locking flange no longer restrict the forward and backward movement of the female locking ring, and the female locking flange no longer restricts the forward and backward movement of the male locking ring. Then, pass the safety pin through the female locking flange and the female flange, and install the cotter pin. At this point, pull the union female head outwards until the locking rod is completely disengaged from the male head locking flange. The union male head and the union female head are then unlocked. This solves the problems of cumbersome operation and inconvenient unlocking and locking of existing flange and bolt connections. Attached Figure Description

Detailed Implementation
[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0017] Please see Figures 1 to 3This utility model provides a high-pressure manifold quick connector with a multi-stage rotary interlocking structure, including a male locking ring 1, a male locking flange 2, a union male connector 3, a female flange 4, a locking rod 5, a locking limit block 6, a female locking flange 7, a female locking ring 8, a union female connector 10, an unlocking limit block 11, and a safety pin 12; the male locking flange 2 is fixedly connected to the union male connector 3 and is located on one side of the union male connector 3; the male locking ring 1 is assembled on the side of the union male connector 3 near the male locking flange 2; the female flange 4 is located on one side of the male locking flange 2; and the union female connector 10 is fixedly connected to the female flange 4. The locking rod 5 is fixedly connected to the female flange 4 and located on the side of the female flange 4 away from the male locking flange 2. The female locking flange 7 is assembled on the side of the male locking flange 10 close to the female flange 4. The locking limit block 6 is assembled on the outside of the female flange 4. The female locking ring 8 is assembled on one side of the female locking flange 7. The unlocking limit block 11 is assembled on the outside of the female flange 4. The safety pin 12 is assembled on one side of the female flange 4 and the female locking flange 7 and passes through the female flange 4 and the female locking flange 7.
[0018] In this embodiment of the utility model, the circumferential rotation of the female locking flange 7 on the union female head 10 is restricted by the locking limit block 6, the unlocking limit block 11, and the safety pin 12. The high-pressure manifold is connected by multiple locking mechanisms, including the male locking ring 1, the female locking ring 8, and the locking rod 5. The unlocking and locking operations are convenient. Specifically, when it is necessary to lock the union male head 3 and the union female head 10, the female locking ring 8 is confirmed to be in the unlocked position. The safety pin 12 is then passed through the female locking flange 7 and the female flange 4. At this time, the locking rod 5 is aligned with the locking hole 13 on the end face of the male locking flange 2, and the union female head 10 is pushed forward so that the locking rod 5 passes through the locking flange 2. The pushing is stopped when the end faces of the union male head 3 and the union female head 10 come into contact. At this time, the male locking flange 2 does not restrict the front end of the female locking ring 8, and the front end of the female locking ring 8 passes through the slotted surface on the male locking flange 2; the female locking flange 7 does not restrict the front end of the male locking ring 1, and the front end of the male locking ring 1 passes through the slotted surface on the female locking flange 7. After removing the cotter pin 14 from the safety pin 12, pull out the safety pin 12. Rotate the female locking ring 8 towards the locking limit block 6 until the side of the female locking ring 8 is flush with the locking limit block 6. Then pass the safety pin 12 through the female locking flange 7 and the female flange 4, and install the cotter pin 14. At this time, the female locking ring 8 also passes through the slotted surface of the locking rod 5. The locking rod 5 and the male locking flange 2 restrict the forward and backward movement of the female locking ring 8, and the female locking flange 7 restricts the forward and backward movement of the male locking ring 1. At this time, the union male head 3 and the union female head 10 are locked. When it is necessary to unlock the union male head 3 and the union female head 10, the cotter pin 14 on the safety pin 12 is removed, the safety pin 12 is pulled out, and the female locking ring 8 is rotated towards the unlocking limit block 11 until the side of the female locking ring 8 is close to the unlocking limit block 11. At this time, the female locking ring 8 is disengaged from the slotted surface of the locking rod 5, and the locking rod 5 and the male locking flange 2 no longer restrict the forward and backward movement of the female locking ring 8, and the female locking flange 7 no longer restricts the forward and backward movement of the male locking ring 1. Next, pass the safety pin 12 through the female locking flange 7 and the female flange 4, and install the cotter pin 14. Then, pull the union female head 10 outwards until the locking rod 5 is completely disengaged from the male locking flange 2. The union male head 3 and union female head 10 are then unlocked. This solves the problems of cumbersome operation and inconvenient unlocking and locking of existing flange and bolt connections.
[0019] Furthermore, the male locking flange 2 has a locking hole 13, which is located on one side of the male locking flange 2.
[0020] In this embodiment of the utility model, the locking hole 13 is provided so that the locking rod 5 can pass through the male locking flange 2.
[0021] Furthermore, the high-pressure manifold quick connector with a multi-stage rotary interlock structure also includes an operating handle 9, which is fixedly connected to the female head locking ring 8 and located at the bottom of the female head locking ring 8.
[0022] In this embodiment of the invention, the operating handle 9 is provided to facilitate the operation of the female head locking ring 8 by the worker.
[0023] Furthermore, the safety pin 12 has a cotter pin 14.
[0024] In this embodiment of the utility model, after the safety pin 12 passes through the female locking flange 7 and the female flange 4, the cotter pin 14 is inserted into the safety pin 12 and cooperates with the safety pin 12 to restrict the circumferential rotation of the female locking flange 7 on the union female head 10.
[0025] The above-disclosed embodiment is merely a preferred embodiment of a high-voltage manifold quick connector with a multi-stage rotary interlocking structure of the present invention. Of course, it should not be construed as limiting the scope of the present invention.
