Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a conical head auxiliary docking device. Background Art
[0002] The fluid pipeline connection joint of disposable consumables for biopharmaceuticals is a commonly used liquid connection method. It realizes the connection of external leakage prevention and internal connection through a conical structure in cooperation with the pipeline, and is widely used in the fields of biopharmaceuticals and the like.
[0003] In the prior art, the connection of the joint with a conical head structure needs to be carried out by manual screwing and squeezing. However, the diameter of the conical head is much larger than the inner diameter of the pipeline, and a large grip force of the hand is required for screwing and squeezing, which causes an obvious sense of compression on the hand. When the number of screwing exceeds a certain amount, it will cause obvious pain to the operator's fingers, posing both a risk of work injury and reducing efficiency. When screwing and squeezing a conical joint with a relatively small size and brittle material by hand, it is also easy to break. Moreover, when screwing and squeezing, the pipeline and the conical joint are not on the same diameter, and particles are easily generated due to wear during repeated disassembly and assembly.

[0036] Such as Figure 8 and Figure 9 As shown, the docking device further includes a limiting structure for restricting the upward movement of the hose chuck 9 and the taper chuck 12;
[0037] Among them, the limiting structure includes a first limiting unit and a second limiting unit. The first limiting unit is used to restrict the upward movement of the hose chuck 9, and the second limiting unit is used to restrict the upward movement of the taper chuck 12. The first limiting unit includes a first convex block 27 provided on the left jaw 7 and a first notch 28 provided on the hose chuck 9. The first convex block 27 is located at the first notch 28.

The second convex block 29 is located at the second notch 30.
[0038] Such as Figure 5 As shown, an elastic member is provided between the left pliers handle 1 and the right pliers handle 2. Connecting columns 24 are provided on the opposite sides of the left pliers handle 1 and the right pliers handle 2. The elastic member is a spring 18 and is sleeved on the outer wall of the connecting column 24.
[0039] Among them, the connecting column 24 makes the spring 18 more stable when being squeezed and avoids a large arc of its outward movement.
[0040] Such as Figure 1 As shown, anti-slip sleeves 4 are sleeved on the outer walls of the left pliers handle 1 and the right pliers handle 2.
[0041] Among them, when the operator squeezes the left pliers handle 1 and the right pliers handle 2, the anti-slip sleeves 4 can avoid the occurrence of slipping.
[0042] It can be understood that when the operator needs to connect the hose part 16 and the flare fitting 17 together, the operator can first place the hose part 16 at the first groove 72 and the flare fitting 17 at the fourth groove 131. Then the operator holds the left pliers handle 1 and the right pliers handle 2 and squeezes them. At this time, the left pliers handle 1 and the right pliers handle 2 rotate and move towards each other, the spring 18 is compressed, and the left pliers handle 1 and the right pliers handle 2 moving towards each other will drive the flare chuck 12 and the hose chuck 9 to operate through the second link 6 and the first link 5 respectively. First, the flare chuck 12 and the hose chuck 9 operate and move downward to clamp the flare fitting 17 and the hose part 16 respectively. At this time, the flare fitting 17 is located in the third groove 121 and the fourth groove 131, and the hose part 16 is located in the first groove 72 and the second groove 91. And through the bumps 73 provided in the first groove 72 and the second groove 91, the hose part 16 can be prevented from slipping. Then the flare chuck 12 and the hose chuck 9 will move towards each other. The flare chuck 12 and the hose chuck 9 moving towards each other drive the clamped flare fitting 17 and hose part 16 to move towards each other, and will also drive the left pliers jaw 7 and the right pliers jaw 8 to move towards each other. The clamped flare fitting 17 and hose part 16 moving towards each other will contact and be squeezed so that the two are connected together. Thus, it is convenient to connect the flare fitting 17 and the hose part 16, improving work efficiency, being more conducive to formulating operation specifications and standards so as to improve product quality, avoiding labor injuries to personnel, and ensuring that the hose part 16 and the flare fitting 17 are on the same level, avoiding wear and the appearance of particles caused by repeated assembly, disassembly, screwing, and squeezing. In addition, through the above structure, the force during operation can be reduced, and longitudinal clamping can be achieved through the flare chuck 12 and the hose chuck 9. Through the first groove 72 and the second groove 91 being conical in shape and the bumps 73 provided on the inner side, transverse clamping can be achieved, making the connection between the hose part 16 and the flare fitting 17 more stable; after connecting the hose part 16 and the flare fitting 17, the operator can release the left pliers handle 1 and the right pliers handle 2, and the spring 18 will reset to drive the left pliers handle 1 and the right pliers handle 2 to reset. Thus, the docking device is in a non-operating state, and through the setting of the spring 18, an effective distance can be maintained between the left pliers handle 1 and the right pliers handle 2 of the docking device for the next operation.
[0043] In summary, by squeezing the left clamp handle 1 and the right clamp handle 2, the left clamp handle 1 and the right clamp handle 2 move towards each other, causing the second connecting rod 6 and the first connecting rod 5 to drive the pagoda chuck 12 and the hose chuck 9 to move downward respectively to clamp the pagoda joint 17 and the hose part 16. Then, continue to squeeze the left clamp handle 1 and the right clamp handle 2. At this time, the pagoda chuck 12 and the hose chuck 9 will move towards each other, thereby connecting the pagoda joint 17 and the hose part 16. This achieves convenient connection, improves work efficiency, is conducive to formulating operation specifications and standards, thus improving product quality, can also avoid labor injuries to personnel, and can ensure that the hose part 16 and the pagoda joint 17 are at the same level, avoiding wear and the appearance of particles caused by repeated assembly, disassembly, screwing and squeezing. In addition, longitudinal clamping is achieved through the pagoda chuck 12 and the hose chuck 9. The first groove 72 and the second groove 91 are conical in shape and convex points 73 are provided on the inner side, which can achieve lateral clamping, making the connection between the hose part 16 and the pagoda joint 17 more stable.
