Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In some embodiments, the present invention provides a convex hoop, as shown in fig. 1 and fig. 2, including a hoop 1 and a sealing pipe 2, as shown in fig. 3 and fig. 4, a convex clip cooperating with the sealing pipe 2 is provided around both ends of the inner side of the hoop 1, an annular sealing groove 11 cooperating with the sealing pipe 2 is formed between the two convex clips, the width of the groove bottom of the annular sealing groove 11 is smaller than the width of the groove opening of the annular sealing groove 11, the edge of the sealing pipe 2 abuts against the groove wall of the annular sealing groove 11, and the sealing pipe 2 is in interference fit with the annular sealing groove 11; and a second sealing groove 14 is formed at the outer side of the convex card. The second sealing groove 14 is used for installing a sealing ring, and double sealing of the pipeline is realized through double functions of the sealing pipe 2 and the sealing ring.

Through setting up special annular seal groove 11 in staple bolt 1's inboard to set up the sealed tube 2 with the cell wall adaptation of annular seal groove 11, because the thickness of 2 tip of sealed tube is less than the thickness at middle part, the pipeline is at the removal in-process, and the deformation that corresponds is changeed to the tip of sealed tube 2, has improved the laminating effect between sealed tube 2 and the pipeline, thereby improves the pipe connection quality.

Illustratively, a cross section of the annular sealing groove 11 is in a trapezoid structure, so that the width of the notch of the annular sealing groove 11 is greater than the width of the groove bottom, and meanwhile, the end portion of the sealing pipe 2 adapted to the notch is attached to the side wall of the annular sealing groove 11, wherein the sealing pipe 2 may be a rubber pipe, and the thickness of the end portion of the sealing pipe 2 is smaller than that of the middle portion, so that the end portion is more easily deformed, and meanwhile, due to the interference fit between the sealing pipe 2 and the annular sealing groove 11, when the pipeline is deviated towards one direction, the end portion of the sealing pipe 2 is deformed along the moving direction of the pipeline, so as to maintain the attachment between the sealing pipe 2 and the pipeline, and thereby reducing the probability of water leakage or air leakage of the pipeline.

In some embodiments, the hoop 1 comprises two detachably connected half rings 12.

Further, the hoop 1 is made of stainless steel materials, and preferably made of 304 stainless steel materials.

During the use, two semi-rings 12 cooperate, cramp each other, make things convenient for the installation of sealing ring, simultaneously, before can making sealed tube 2 not take place interference fit with annular seal groove 11, be connected with the pipeline earlier to make the sealed tube 2 and be connected between the pipeline easier, improve staple bolt 1's installation convenience.

In some embodiments, half-ring 12 is integrally cast.

The fashioned semi-ring 12 of integrative casting possesses difficult fracture, non-deformable, and the high characteristics of heat-resisting degree simultaneously can improve the structural strength of semi-ring 12, reduces staple bolt 1 probability that bursts in the use to improve the explosion-proof ability of protection.

In some embodiments, as shown in fig. 3, the edge of the half ring 12 is provided with a connecting plate 13, and the connecting plate 13 is provided with a plurality of connecting holes 131.

Through connecting plate 13 cooperation connecting hole 131 for the contact site of two semi-rings 12 is a plane, has increased the area of contact between two semi-rings 12, has improved the structural strength at semi-ring 12 border, reduces the probability that staple bolt 1 damaged, simultaneously, is convenient for align two semi-rings 12, makes things convenient for the assembly.

In some embodiments, a thread-off prevention is provided in the connection hole 131.

Illustratively, the two half rings 12 are connected through bolts matched with the connecting holes 131, and the connecting holes 131 are matched with the thread structures, so that the probability of sliding of the bolts in the connecting holes 131 is reduced, the connection stability between the two half rings 12 is improved, and the overall structural strength of the hoop 1 is improved.

In some embodiments, as shown in fig. 5, a reinforcing groove 121 is formed around the outer side of the half ring 12, and the end of the reinforcing groove 121 is close to the connection hole 131.

In use, traction members may be added to the reinforcement groove 121, such as: iron wire, steel rope, etc.; both ends of the pulling member are fixed to bolts for connecting the half rings 12, respectively, and the pulling member tightens the half rings 12, thereby improving the mechanical strength of the half rings 12.

In some embodiments, as shown in fig. 6, the edge of the connecting plate 13 is provided with an arc-shaped cut 132. The arc-shaped cut 132 of the connecting plate 13 is convenient for being held by hands, and meanwhile, processing raw materials are saved.

In some embodiments, the corners of the web 13 are provided with rounded corners 133. Through the setting of fillet 133, improve staple bolt 1's safety in utilization, reduce the probability that causes the injury to the staff in the installation.

In some embodiments, the hoop 1 is plated with a rust-proof layer. The antirust layer can reduce the probability that the anchor ear 1 gets damp and rusts, thereby reducing the probability that the anchor ear 1 is damaged.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
