Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a hoop. Background Art

[0002] A hoop is a fastener used for pipe connection. It is made of metal and has certain strength and toughness, which can play a role in fixing and strengthening at the pipe connection. During the installation of the hoop, a certain torque needs to be applied to tighten the bolt. If the torque is too large, the bolt is likely to fall off. Content of the Utility Model

[0003] In order to solve the above technical problems existing in the prior art, the utility model provides a hoop.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A hoop includes a first hoop ring and a second hoop ring. The first hoop ring has a first connection part, the second hoop ring has a second connection part, the first connection part and the second connection part are connected by a bolt, and a pressing member is further arranged between the first connection part and the second connection part. One end of the pressing member contacts the first connection part, and the other end contacts the second connection part.

[0006] By using the hoop of the utility model, by arranging a pressing member between the first connection part and the second connection part, when a torque is applied to tighten the bolt and the first hoop ring and the second hoop ring are assembled in place, the pressing member is pressed between the first connection part and the second connection part, and the pressing member provides a pressing force to the first connection part and the second connection part. Even if the bolt is slightly loosened during subsequent use, the bolt will not fall off.

[0007] On the basis of the above technical solution, the utility model can further make the following technical improvements:

[0008] Further, the pressing member is a bent member or a gasket.

[0009] Further, the bent member is an arc-shaped member.

[0010] The beneficial effect of adopting the above further technical solution is that by setting the bent member as an arc shape, during the application of torque, it is beneficial to the transmission of torque, and it can effectively prevent the deformation and breakage of the bent member. Thus, during subsequent use, the bent member can provide a pressing force to the first connection part and the second connection part, thereby preventing the bolt from falling off.

[0011] Further, the bent member is fixedly connected to the end of the first connection part and / or the second connection part.

[0012] Furthermore, there are two bending members, and the two bending members are respectively fixedly connected to the first connecting portion and the second connecting portion.

[0013] The beneficial effect of adopting the above further technical solution is that by arranging bending members bent towards the opposite side at the ends of the first connecting portion and the second connecting portion, the loosening of the bolts can be effectively prevented.

[0014] Furthermore, the gasket is an annular gasket.

[0015] Furthermore, the annular gasket is sleeved on the bolt, and the inner diameter of the annular gasket is adapted to the outer diameter of the bolt.

[0016] The beneficial effect of adopting the above further technical solution is that by sleeving an annular gasket on the bolt, the loosening of the bolt can be effectively prevented.

[0017] Compared with the prior art, the utility model has the following technical effects:

[0018] For the hoop provided by the utility model, by arranging a pressing member between the first connecting portion and the second connecting portion, when the bolt is tightened by applying torque and the first hoop and the second hoop are assembled in place, the pressing member is pressed between the first connecting portion and the second connecting portion, and the pressing member provides a pressing force to the first connecting portion and the second connecting portion. Even if the bolt loosens slightly during subsequent use, the bolt will not fall off. BRIEF DESCRIPTION OF THE DRAWINGS
