Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1 and 2, an occluder for a plastic tube includes: the framework 100 comprises an upper pressing plate 110, a lower pressing plate 120 and a plurality of elastic connecting rods 130 connected between the upper pressing plate 110 and the lower pressing plate 120, wherein the elastic connecting rods 130 are distributed around the circumference of the upper pressing plate 110/the lower pressing plate 120, and the middle parts of the elastic connecting rods 130 are slightly bent outwards under a normal state; the expansion sleeve 200 is coaxial with the framework 100 and sleeved outside the elastic connecting rod 130, and the upper end face and the lower end face of the expansion sleeve 200 are respectively connected with the upper pressing plate 110 and the lower pressing plate 120 in a sealing manner; an adjusting screw 300 connected between the upper platen 110 and the lower platen 120; when the adjusting screw 300 is rotated, the upper pressing plate 110 and the lower pressing plate 120 move relatively close to each other, the elastic link 130 is further bent outward, and the expansion sleeve 200 expands outward.

As shown in fig. 1, the upper platen 110 and the lower platen 120 are coaxially installed, the frame 100 is cylindrical in shape in normal state, and the upper and lower ends of the elastic connecting rod 130 are respectively connected to the upper platen 110 and the lower platen 120 and are distributed around the circumference of the upper platen 110 and the lower platen 120. The middle portion of each elastic link 130 is slightly curved in a normal state, i.e., slightly curved in a direction away from the central axis of the frame 100. The adjustment screw 300 is connected between the upper platen 110 and the lower platen 120, and by rotating the adjustment screw 300, the upper platen 110 and the lower platen 120 can be moved relatively closer to or farther away from each other. As shown in fig. 2 and 3, when the upper platen 110 and the lower platen 120 move relatively close to each other, the elastic links 130 are further bent outward at the same time, i.e., the middle portion of the frame 100 bulges outward, and the slight outward bending shape of the elastic links 130 in the normal state facilitates the further outward bending action. The expansion sleeve 200 is wrapped around the elastic connecting rod 130, and when the upper pressing plate 110 and the lower pressing plate 120 move relatively close to each other, the upper end and the lower end of the expansion sleeve 200 are compressed by the pressure of the upper pressing plate 110 and the lower pressing plate 120, respectively, and the expansion sleeve 200 expands outwards by the outward bending force of the elastic connecting rod 130. When the plugging device is used, the plugging device is arranged at the port of a plastic pipe channel of a cable, the outer wall of the expansion sleeve 200 is attached to the inner wall of the cable channel through the expansion effect of the expansion sleeve 200, so that the port of the cable channel is plugged quickly, and the expansion sleeve 200 is guaranteed to be fully plugged through the bending effect of the elastic connecting rod 130 and the expansion effect of the expansion sleeve 200. The plugging device can be recycled, the expansion sleeve 200 is likely to have aging problems after long-time use, and the acting force of the elastic connecting rod 130 on the expansion sleeve 200 can be utilized, so that the expansion sleeve 200 can be stably expanded to plug the port of the cable channel.

In some embodiments of the present invention, the upper plate 110 is provided with a stepped air hole 111, and the air hole 111 is provided with a cock 112. A sealed cavity is formed among the upper pressure plate 110, the lower pressure plate 120 and the expansion sleeve 200, and when the upper pressure plate 110 and the lower pressure plate 120 move relatively close to each other, air in the sealed cavity is compressed to form strong pressure, so that further movement of the upper pressure plate 110 and the lower pressure plate 120 is blocked. At this time, the gas in the sealed cavity is discharged through the gas hole 111, and the gas hole 111 is sealed by using the cock 112 after the operation is completed, thereby facilitating the expansion process of the expansion sleeve 200.

In some embodiments of the present invention, at least four adjusting screws 300 are disposed between the upper pressing plate 110 and the lower pressing plate 120, and each adjusting screw 300 is distributed around the central axis of the frame 100 at equal intervals. As shown in fig. 1 and 4, four adjusting screws 300 are connected between the upper pressing plate 110 and the lower pressing plate 120, the distance between the adjacent adjusting screws 300 around the central axis of the framework 100 is 90 degrees, the expansion sleeve 200 is synchronously expanded by using each adjusting screw 300, and then the corresponding positions of the expansion sleeve 200 are locally compressed by using each adjusting screw 300, so that the outer wall of the expansion sleeve 200 is fully attached to the inner wall of the cable channel to realize plugging.

In some embodiments of the present invention, the upper end and the lower end of the expansion sleeve 200 are connected to the upper pressing plate 110 and the lower pressing plate 120 by clamping. As shown in fig. 5, the upper and lower ends of the expansion sleeve 200 are T-shaped, and are connected to the grooves of the upper and lower

pressing plates

110 and 120 by snap-fitting.

As shown in fig. 1, in some embodiments of the present invention, a pattern 210 is disposed at the middle portion of the outer wall of the expansion sleeve 200, and the expansion sleeve 200 mainly expands at the middle portion thereof, so as to increase friction between the expansion sleeve and the inner wall of the cable channel through the pattern 210.
