[0062] Pipe 2 DETAILED DESCRIPTION

[0063] The utility model will be described below in a preferred embodiment and in conjunction with the drawings for a more complete and clear understanding.

[0064] As Figures 1-7 shown, the embodiment provides a flow stop clamp 1 for compressing a pipe 2, the flow stop clamp 1 comprising a first cooperating structure 11 and a second cooperating structure 12, the first cooperating structure 11 comprising a first housing 111, a first connecting part 112, and at least one first locking part 113, the second cooperating structure 12 comprising a second housing 121, a second connecting part 122, at least one second locking part 123, and a compression member 126.

[0065] The first housing 111 and the second housing 121 are made of transparent material, which facilitates the user to observe whether the first locking part 113 and the second locking part 123 are in the locked state and whether the compression member 126 has formed a flow stop degree compression on the pipe 2.

[0066] The first connecting part 112 and the second connecting part 122 are rotatably connected, so that the flow stop clamp angle α between the first housing 111 and the second housing 121 is variable. When α = 0°, the compression member 126 can compress the surface of the pipe 2 to completely stop the flow of the pipe 2, and the first locking part 113 and the second locking part 123 are locked and cannot be released. In this way, the demand for one-time flow stop of the pipe 2 without opening again can be met.

[0067] The first shell 111 and the second shell 121 are arranged to cover the outside of the compression piece 126, the first locking part 113 and the second locking part 123, so as to further protect the first locking part 113 and the second locking part 123, and prevent external forces from causing the first locking part 113 and the second locking part 123 to accidentally disengage from the locked state, and also prevent external forces from causing the compression piece 126 to accidentally disengage from the pipe 2.

[0068] In this embodiment, the first matching structure 11 also includes a first connection side recess 114, and the first connection side recess 114 and the first connection portion 112 are both located on the same side of the first shell 111. The second matching structure 12 also includes a second connection side recess 124, and the second connection side recess 124 and the second connection portion 122 are both located on the same side of the second shell 121. The sizes of the first connection side recess 114 and the second connection side recess 124 correspond to the cross-sectional size of the pipe 2, and the two ends of the first connection side recess 114 and the two ends of the second connection side recess 124 are smoothly connected. The pipe 2 is inserted into the first connection side recess 114 and the second connection side recess 124. In this way, the pipe 2 can be matched with the first matching structure 11 and the second matching structure 12 at the same time, and the problem of the pipe 2 slipping and being scratched or punctured by the matching parts is avoided.

[0069] Please refer back to Figure 6 、 Figure 7 In this embodiment, 0°≤α≤150°. When α=150°, the side wall of the second connecting side recess 124 abuts against the surface of the pipe 2 to form a limiting state. In other embodiments, the maximum value of the flow-stopping angle is determined according to the limiting state of the second matching structure 12. If the pipe can be completely embedded in the first connecting side recess, the maximum value of the flow-stopping angle can reach or even exceed 180°, and when no one touches the flow-stopping clamp 1, the second matching structure 12 can still maintain the position at the maximum flow-stopping angle.

[0070] In this embodiment, the first mating structure 11 further includes a first opening-side recess 115, which is located on a side of the first housing 111 away from the first connecting portion 112. The size of the first opening-side recess 115 corresponds to the cross-sectional size of the pipe 2. The pipe 2 is embedded in the first opening-side recess 115. This reduces the possibility of the pipe 2 rotating within the first mating structure 11, thereby reducing friction and ensuring a more stable mating between the pipe 2 and the first mating structure 11.

[0071] In the embodiment, the second cooperation structure 12 further comprises a second open side notch 125, which is located on the side of the second cooperation structure 12 away from the second connecting part 122, and the size of the second open side notch 125 corresponds to the cross-sectional size of the pipeline 2. When α = 0°, the two ends of the second open side notch 125 and the two ends of the first open side notch 115 are smoothly connected, and the pipeline 2 is arranged in the passage formed by the first open side notch 115 and the second open side notch 125. In this way, the pipeline 2 and the second cooperation structure 12 can be further stably matched when the flow stopping clamp angle α is 0°.

[0072] Please refer to Figure 5 In the embodiment, the first locking part 113 is an outer hook member, and the second locking part 123 is an inner hook member. When α = 0°, the inner side of the outer hook member and the inner side of the inner hook member are hooked with each other, and the relative movement of the outer hook member and the inner hook member is limited. When an external force wants to expand the flow stopping clamp angle α again, the outer hook member and the inner hook member are locked, and the trend of expansion can be prevented. In this way, the first locking part 113 and the second locking part 123 can be locked in a stable and simple structure.

[0073] In the embodiment, the outer side of the outer hook member is provided with a first guide slope 116, the outer side of the inner hook member is provided with a second guide slope 127, and the first guide slope 116 and the second guide slope 127 are matched. In this way, after the outer hook member and the inner hook member are contacted, they can smoothly slide to the hooked state through the matched first guide slope 116 and second guide slope 127, and the first locking part 113 and the second locking part 123 can be smoothly locked.

[0074] In the embodiment, the second shell 121 is provided with a containing through hole 128 which is in communication with the outer side, and the end of the inner hook member is located in the containing through hole 128. In this way, when necessary, a tool can be inserted into the containing through hole 128 to push away the inner hook member and the outer hook member, and the flow stopping clamp 1 can be provided with a safety redundancy.

[0075] In the embodiment, the first cooperation structure 11 is provided with two first locking parts 113, and the two first locking parts 113 are symmetrically distributed along the axis A of the pipeline 2. The second cooperation structure 12 is provided with two second locking parts 123, and the two first locking parts 113 are symmetrically distributed along the axis A of the pipeline 2. In this way, the two pairs of first locking parts 113 and second locking parts 123 are symmetrically locked along the axis A of the pipeline 2, the pressure applied by the pressing member 126 to the pipeline 2 is more symmetrical, the flow stopping effect is improved, and the flow stopping clamp 1 is provided with a safety redundancy, so that the damage of a single locking part does not cause the flow stopping clamp 1 to be locked.

[0076] In the embodiment, when the angle α is 0°, the side of the first shell 111 and the side of the second shell 121 are in close contact, so that the protection effect of the compression member 126, the first locking portion 113 and the second locking portion 123 can be improved.

[0077] In the embodiment, the material of the flow-stopping clamp 1 is polypropylene, so that the flow-stopping clamp 1 is reasonable in cost, firm and durable, can withstand various disinfection methods, and meets the use requirements in the medical field.

[0078] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, but these changes and modifications all fall within the protection scope of the present application.
