Technical Field

[0001] The utility model relates to the technical field of pull-ring combination covers, in particular to a pull-ring combination cover for an infusion container. Background Art

[0002] The pull ring combination cover for infusion container is a cover used to seal and protect infusion container. Infusion container is a container commonly used in the medical field to hold medicine or liquid, and the medicine or liquid is delivered to the patient through the infusion line. The main function of the pull ring combination cover is to ensure the sealing of the infusion container, prevent liquid leakage and contamination, and provide a convenient way to open and close.

[0003] The existing pull-ring combination cover cannot limit the pull ring, and may be accidentally opened during transportation, causing leakage, or the pull ring may become loose after a long period of time, which may also cause accidental opening and leakage. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: a pull ring combination cover for an infusion container, comprising a combination cover, a pull ring is arranged on the top of the combination cover, and a limit assembly is arranged on the surface of the combination cover and the pull ring, and the limit assembly comprises:

[0006] A groove, wherein the groove is provided on the surface of the combined cover, the inner wall of the groove is rotatably connected with a rotating rod, a stabilizing plate is passed through the top of the rotating rod, the stabilizing plate is fixedly connected to the rotating rod, a rubber ball is fixed on the surface of the rotating rod, a resistance groove is provided on the inner side of the groove, the limiting assembly also includes a resistance piece, the stabilizing plate can limit the pull ring to prevent the pull ring from opening and causing leakage when the pull ring is transported or not needed, and at the same time, the surface of the rubber ball resists the inner wall of the resistance groove, so that the rotating rod is limited to prevent self-rotation.

[0007] Preferably, the resistance member includes a second resistance groove, which is opened on the top of the pull ring, and a second rubber ball is fixed to the bottom of the stabilizing plate. When there is no need to pull the pull ring, the surface of the second rubber ball contacts the second resistance groove, which can limit the pull ring and the stabilizing plate to prevent further rotation, causing the stabilizing plate to move away from the pull ring, and preventing the pull ring from accidentally opening and leaking.

[0008] Preferably, an anti-skid groove is provided on the surface of the combined cover to prevent a person's hands from slipping when the combined cover is connected to the infusion container.

[0009] Preferably, the inner side of the combined cover is provided with an internal thread, and the threaded connection can improve the connection stability and increase the sealing performance.

[0010] Preferably, the rotating rod is configured to be cylindrical so that the rotation of the rotating rod will not cause any obstruction.

[0011] Preferably, the diameter of the groove is larger than that of the rotating rod, and the gap between the groove and the rotating rod allows the rubber ball to be squeezed and passed normally.

[0012] Compared with the prior art, the utility model provides a pull ring combination cover for an infusion container, which has the following beneficial effects:

[0013] 1. The pull ring combination cover for the infusion container is provided with a limiting assembly, and the stabilizing plate is located above the pull ring. At the same time, the rubber ball 1 is in contact with the inner wall of the contact groove 1, and the rubber ball 2 is in contact with the inner wall of the contact groove 2, so that the rotating rod and the stabilizing plate can be stabilized to avoid the rotating rod and the stabilizing plate from rotating during transportation. The stabilizing plate can limit the pull ring to prevent the pull ring from accidentally opening and causing leakage.

[0014] 2. The pull-ring combined cover for the infusion container has an anti-skid groove, which prevents hands from slipping when the combined cover is threadedly connected to the infusion container. The threaded connection can provide better sealing through the provided internal thread. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a pull ring combination cover for an infusion container, comprising a combination cover 1, a pull ring 4 is arranged on the top of the combination cover 1, and a limit assembly 5 is arranged on the surface of the combination cover 1 and the pull ring 4. The limit assembly 5 includes: a groove 50, a rotating rod 51, a stabilizing plate 52, a resistance groove 1 53, a rubber ball 1 54, a resistance piece 55, a resistance groove 2 550, and a rubber ball 2 551.

[0021] The groove 50 is provided on the surface of the combined cover 1, and a rotating rod 51 is rotatably connected to the inner wall of the groove 50. A stabilizing plate 52 runs through the top of the rotating rod 51, and the stabilizing plate 52 is fixedly connected to the rotating rod 51. A rubber ball 54 is fixed to the surface of the rotating rod 51, and a resistance groove 53 is provided on the inner side of the groove 50. The limiting assembly 5 also includes a resistance member 55, and the resistance member 55 includes a resistance groove 550. The resistance groove 550 is provided on the top of the pull ring 4, and a rubber ball 551 is fixed to the bottom of the stabilizing plate 52. The stabilizing plate 52 is located above the pull ring 4, and at the same time, the rubber ball 54 is in contact with the inner wall of the resistance groove 53, and at the same time, the rubber ball 551 is in contact with the inner wall of the resistance groove 550, so that the rotating rod 51 and the stabilizing plate 52 can be stabilized to prevent the rotating rod 51 and the stabilizing plate 52 from rotating during transportation. The stabilizing plate 52 can limit the pull ring 4 to prevent the pull ring 4 from accidentally opening and causing leakage.

[0022] An anti-skid groove 2 is provided on the surface of the combined cover 1 to prevent hands from slipping when the combined cover 1 is threadedly connected to the infusion container. An internal thread 3 is provided on the inner side of the combined cover 1, and the threaded connection can provide better sealing. The rotating rod 51 is set to be cylindrical, and the rotating rod 51 can rotate normally.

[0023] The diameter of the groove 50 is larger than that of the rotating rod 51, and the gap between the groove 50 and the rotating rod 51 allows the rubber ball 54 to pass through normally.

[0024] When the combined cover 1 is needed, it can be connected to the infusion container through the internal thread 3. The threaded connection can provide better sealing. At the same time, when there is no need to pull the pull ring 4, the stabilizing plate 52 is located above the pull ring 4. At the same time, the rubber ball 1 54 is in contact with the inner wall of the contact groove 1 53, and the rubber ball 2 551 is in contact with the inner wall of the contact groove 2 550. The rotating rod 51 and the stabilizing plate 52 can be stabilized to prevent the rotating rod 51 and the stabilizing plate 52 from rotating during transportation, causing the pull ring 4 to open accidentally and cause leakage. When the pull ring 4 needs to be pulled, the stabilizing plate 52 is rotated. At this time, the rubber ball 1 54 and the rubber ball 2 551 are deformed. At this time, the rubber ball 1 54 and the rubber ball 2 551 are separated from the contact groove 1 53 and the contact groove 2 550, so that the stabilizing plate 52 is away from the pull ring 4. At this time, the person can pull the pull ring 4 normally.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
