Embodiment 1
[0048] A hose clamping mechanism, as shown in Figure 5, includes a hose joint 4 coaxial with the hose 3, an inner cone nut 1 and a pipe bolt 2, the outer diameter of the hose joint 4 is the same as that of the hose 3 The apertures of the inner holes match, and the inner cone nut 1, as shown in Figure 6, has a large aperture end as a screw-in end, and the corresponding small aperture end is the end of the inner cone nut 1; the inner cone nut 1 The thread is a tapered thread, and the small diameter A of the thread at the end of the inner cone nut 1 is slightly larger than the outer diameter of the hose; the pipe bolts 2, as shown in Figure 7 and Figure 8, have threaded ends evenly distributed 2 along the circumferential direction of the pipe wall More than one strip mouth parallel to the central axis, the inner diameter C of the central hole is slightly larger than the outer diameter of the hose. When using this hose clamping device to clamp the hose, first insert the hose joint...
Embodiment 2
[0056] As shown in Figure 9, it is another embodiment of the hose clamping device. The difference from Example 1 is that in order to improve the reliability of the connection or to be used in occasions with high working pressure, the end of the hose joint 4 has a set of anti-falling protruding edges 8, and the outer diameter of the anti-falling protruding edges 8 Close to or slightly larger than the inner diameter of the hose 3; along the direction from the end of the hose joint 4 to the end of the joint, the outer diameter of the anti-falling protrusion 8 increases sequentially; there is no anti-falling protrusion on the hose joint 4 The pipe section along the edge has a round boss 7 formed by a smooth increase in outer diameter near the inside of the head. The outer diameter end of the round boss 7 is closely fitted with the hose, and the round boss 7 is the hose. The connection between the pipe section of the joint and the pipe head. The pipe section without anti-falling o...
Embodiment 3
[0058] As shown in Figure 10, it is also an embodiment of the present invention. The difference from Embodiment 2 is that there are flanges 9 and 9' on the inner sides of the two ends of the pipe bolt 2 respectively, and the flanges 9 and 9' The inner diameter of the pipe is slightly larger than the outer diameter of the flexible pipe; the joint between the flange 9 and the flexible pipe away from the head of the pipe bolt 2, that is, the clamping position, is arc-shaped. This design is also to increase the clamping force, make the connection reliable, or be used in occasions with high working pressure.
[0059] The hose joint 4 of the present invention can be a joint of symmetrical shape that connects two or more directions, so as to realize the connection between two or more hoses. As shown in FIG. 11 , double hose connectors 6 connected symmetrically to one another are adopted, and the rest of the structure is the same as that in Embodiment 2, which is used for clamping and...
