In addition, the inner sidewall of the sealing ring 40 is provided with a plurality of sealing collars to improve sealing effect.

The end of the connecting flange 20 facing the gland 30 is provided with a conical counter bore coaxially arranged with the second through hole, and a combined pressing ring 50 is arranged in the conical counter bore, and it should be noted that the combined pressing ring 50 can also be independently applied to the anti-drop pipe joint with other structures, that is, the embodiment essentially provides a combined pressing ring.

The combined pressing ring 50 provided in this embodiment includes an extrusion ring 51 having an opening and an anti-drop assembly 52 located in the extrusion ring 51, that is, the extrusion ring 51 has a fracture, specifically, the extrusion ring 51 includes an annular support plate 61 and an annular baffle 62 directly or indirectly integrally connected to the outer periphery of the annular support plate 61, in this embodiment, a thickening baffle 63 is integrally connected between the annular support plate 61 and the annular baffle 62, so as to adjust the thickness of the extrusion ring 51 according to the thickness requirement of the anti-drop assembly 52, the thickening baffle 63 is integrally connected to the outer periphery of the annular support plate 61, and the annular baffle 62 is integrally connected to the annular support plate 61 indirectly through an integral connection to one end of the thickening baffle 63 far from the annular support plate 61. Further, the annular shutter 62 is gradually inclined (i.e., inwardly inclined, tapered) toward the axial direction of the annular support plate 61 from one end relatively close to the annular support plate 61 toward the opposite end.

The anti-drop assembly 52 comprises a plurality of plate groups which are annularly arranged in sequence and respectively abut against the annular baffle plate 61, and the anti-drop assembly 52 also has a fracture which is the same as the fracture of the extrusion ring 51, that is, each plate group is sequentially arranged around the inner side wall of the annular baffle plate 62. The plate set includes a plurality of arc plates 64 stacked in order along the axis of the annular support plate 61 (i.e., the central axis of the annular support plate 61), and it should be noted that the arc plates 64 are planar plates, and are arc-shaped on one side facing the axis of the annular support plate 61 and on the opposite side. The arcuate plates 64 are arranged flush toward one side of the axial direction of the annular support plate 61, and the opposite side is directly or indirectly abutted against the annular baffle plate 62, specifically, each arcuate plate 64 is directly abutted against the annular baffle plate 62 at a position corresponding to the annular baffle plate 62, and each arcuate plate 64 is indirectly abutted against the annular baffle plate 62 by being abutted against the thickening baffle plate 63 at a position corresponding to the thickening baffle plate 63.

Preferably, in the present embodiment, the side of the arc plate 64 facing the axial direction of the annular support plate 61 has a tooth locking portion with a thickness gradually decreasing from the side facing away from the axial direction of the annular support plate 61 to the opposite side (i.e., the side closer to the annular support plate 61), which helps to reduce the contact area between the arc plate 64 and the pipe, and thus can increase the pressure of the arc plate 64 on the pipe, and improve the anti-drop capability. In addition, the pad 67 is clamped between two adjacent arc plates 64 in the same plate group, the pad 67 is different from the arc plates 64 in that the pad 67 is not provided with locking teeth, the thickness of the pad 67 is smaller than that of the arc plates 64, specifically, one end of the pad 67 is integrally connected with a second lug 68, the directions of one ends of two adjacent pad 67 in the same plate group, which are connected with the second lugs 68, are opposite, through holes are formed in the second lugs 68, the through holes are preferably strip holes or waist-shaped holes, the second lugs 68 at the opposite ends of two adjacent plate groups are arranged in a staggered manner, and the connecting pins 66 are simultaneously inserted into the through holes at corresponding positions, so that the distance between the two adjacent locking teeth in the same plate group can be adjusted by using the pad 67.

The outer peripheral wall of the annular baffle 62 of the combined clamping ring 50 abuts against the inner side wall of the conical counterbore of the connecting flange 20 and the end face of the gland 30 abuts against the annular support plate 61 of the combined clamping ring 50, i.e. the annular support plate 61 of the combined clamping ring 50 is arranged relatively close to the gland 30. In addition, the joint body 10 and the connecting flange 20 and the gland 30 are fixedly connected through bolt connection structures, the bolts of the two can be the same bolt, and the specific connection structure is the same as that adopted in an anti-drop pipe joint disclosed in chinese patent publication No. CN216715490U, which is not the focus of this embodiment, and is not described in detail here.
