Background technique:

Steel belt elastic hose clamp, commonly known as spring clamp, is made of spring steel, simple structure, convenient processing, low cost, quick installation, strong sealing performance, and its own elasticity can affect the The pipeline provides long-term tightening force compensation, and is generally used in flow/gas pipelines with no pressure or lower pressure requirements.

The traditional spring clamp is stamped by a spring steel strip to form a circular ring shape, leaving two clamping ears on the outer ring of the circular steel strip. When in use, it is necessary to use calipers to clamp both ears forcefully, so that the inner ring of the circular steel belt becomes larger before it can be inserted into the round pipe, and then the calipers are loosened, and the spring clamp is fastened to the pipeline at this time.

However, although the sealing and torque compensation performance of the spring clamp is better, the product itself has no structural constraints, so its resistance to pull-out is low, especially in the pipeline system with a working pressure greater than 0.15MPa, the spring clamp It is easy to loosen and can not play the role of tightening connection.



Technical realization elements:

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a steel belt type elastic hose clamp with scientific and reasonable design, simple structure, convenient operation, anti-deformation, and ensuring the tight connection of pipelines.

The utility model solves its technical problems by adopting the following technical solutions:

A steel band type elastic hose clamp includes a spring clamp body, the spring clamp body is composed of a band ring and two clamping ears made on the outer ring of the band ring, and is characterized in that: The clamping ear on one side is provided with an adjusting screw hole, and the clamping ear on the other side is provided with a through hole at a position corresponding to the adjusting screw hole; and an adjusting screw is further included. , Screw and threading head, the head of the screw is provided with a nut, the tail of the screw is provided with a threading head, the diameter of the threading head is smaller than the diameter of the screw, the boss formed between the threading head and the screw A resisting portion is formed, the diameter of the threading hole is larger than the diameter of the threading head and smaller than the diameter of the screw, the screw thread of the adjusting screw is fitted to the adjusting screw hole on the clamping ear, and the threading head of the adjusting screw is inserted The mounting hole of the clamping ear.
