Steel clamp with good locking degree

Abstract

The utility model provides a steel clamp with good locking degree, which comprises a male semi-ring and a female semi-ring, and the lower part of the male semi-ring is connected with the female semi-ring. The utility model has the advantages that: before the bolt and the nut are mounted, the clamping block structure is mounted, the clamping block is clamped on the surfaces of the male semi-ring and the female semi-ring joints, and the extension spring is in a tensile state at the moment, so that the joints are mutually locked and tightly held, and the male semi-ring and the female semi-ring jointly hold the rubber ring and tightly hold the joint of the pipeline; through the action of the extension spring, the clamping block can lock the connector and the steel clamp in advance. By means of the pre-locking mode, it can be guaranteed that the pipeline obtains good stability in the initial stage, and when the bolt and the nut are installed for further locking, due to the fact that the connector and the steel clamp are locked by the clamping block in advance, the bolt and the nut can achieve expected locking force more easily. By means of the design, it can be guaranteed that the pipeline joint has higher locking force, and therefore the stability and safety of a pipeline system are improved.

Description

Technical Field

[0001] The utility model relates to the technical field of pipeline steel clamps, in particular to a steel clamp with good locking degree. Background Art

[0002] Pipeline steel clamp is a fixture used to fix and connect pipes and their accessories, also known as clamp or steel clamp. The following is a detailed introduction to pipeline steel clamp:

[0003] Pipeline steel clamps are usually made of steel or stainless steel and are strong and durable.

[0004] For conventional steel clamps, after clamping the two half hoops on the outside of the pipe connection, thread the bolts and then tighten the nuts to complete the installation of the pipe steel clamp.

[0005] However, bolt and nut connections are prone to loosening under vibration, temperature changes or long-term loads. This loosening will reduce the locking degree of the steel clamp and affect the stability of the pipeline connection. During the installation process, if sufficient pre-tightening force is not properly applied, the friction between the bolt and nut will not be enough to maintain the stability of the connection. Insufficient pre-tightening force is one of the common causes of locking defects.

[0006] Therefore, a new steel clip with good locking degree is proposed to solve the above problems. Utility Model Content

Before installing the bolts and nuts, the block can pre-lock the joint and the steel clamp through the action of the tension spring. This pre-locking method can ensure that the pipeline obtains good stability in the initial stage. When the bolts and nuts are installed for further locking, since the joint and the steel clamp have been pre-locked by the block, the bolts and nuts can more easily reach the expected locking force.
