Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal hoses, in particular to an S-shaped shock-isolating metal hose. Background Art
[0002] In industrial applications, especially in high temperature, high pressure and vibration environments, metal hoses are widely used to transport fluids and gases. Traditional metal hoses are usually designed in straight tube form or simple curved shapes. Although these designs perform well in some applications, they often cannot provide ideal performance in complex or highly vibrating environments. In particular, these traditional hoses are prone to rupture or disconnection when encountering earthquakes or other similar vibrations due to the lack of effective seismic isolation design, leading to safety accidents and operational failures.
[0003] A Chinese patent with application number 202220074082.4 discloses a flexible connection structure for an ultra-large-angle deformable pipe with a vibration isolation function, and discloses the following technical solution: In view of the fact that the pipes in existing general buildings are densely distributed and the space is small, how to solve the problem of large earthquake displacement compensation in a small space, the following solution is proposed, which includes a pipe fitting, a bellows is provided in the middle position of the pipe fitting, and a group of hinge seats are fixedly connected to the top and bottom of the pipe fitting, and the number of hinge seats in a group is two, and the two hinge seats in a group are respectively located on both sides of the bellows, and a connecting rod is fixedly connected to one side of one hinge seat in a group of hinge seats; the utility model combines the advantages of a compensator and a metal hose, while satisfying the absorption of larger displacements, achieving self-restraint, safety and reliability. The utility model has a simple structure, excellent performance, substantial characteristics and significant progress, and fills a gap in building seismic isolation pipe displacement compensation products.
[0004] However, the installation and use of this type of seismic isolation connecting rod mechanism is likely to interfere with the surrounding piping system, so an S-shaped seismic isolation metal hose is designed to solve the above technical problems. Utility Model Content
[0005] The utility model aims to provide an S-shaped shock-isolating metal hose to solve the above-mentioned problem.
[0006] In order to solve the above technical problems, the utility model provides an S-shaped seismic isolation metal hose, comprising:
[0007] A metal hose, wherein metal pipes are installed at both ends of the metal hose, a flange is installed on one side of the metal pipe, a positioning piece is sleeved on the metal hose, and a first inflection point and a second inflection point are provided on the metal hose;
[0008] A connecting rod assembly, wherein both ends of the connecting rod assembly are fixed on the metal pipe, and the middle position of the connecting rod assembly is fixed on the surface of the positioning member. The connecting rod assembly is composed of a continuous four-bar linkage, and the width of the connecting rod mechanism is smaller than the distance between the horizontal lines of the first inflection point and the second inflection point.
[0009] Furthermore, both ends of the metal hose are sleeved with metal ring sleeves.
[0010] Furthermore, the metal hose is a corrugated tube, a mesh sleeve is provided on the surface of the corrugated tube, and two ends of the mesh sleeve are located between the metal ring sleeve and the metal hose.
[0011] Furthermore, the bellows is S-shaped.
[0012] Furthermore, the mesh sleeve, the metal ring sleeve and the metal connecting pipe are fixed by welding.
[0013] Furthermore, the four-bar linkage is a quadrilateral, and both ends of the four-bar linkage are fixed to the metal pipe through pins, and the middle position of the four-bar linkage is fixed to the positioning piece through a pin.
[0014] The beneficial effects of the utility model are:
[0015] 1. The distance between the parallel line of the first inflection point along the length direction of the metal hose and the horizontal line of the second inflection point along the length direction of the metal hose is smaller than the width of the connecting rod mechanism, so that the end of the connecting rod mechanism will not protrude from the position H of the horizontal line when it is contracted, preventing the connecting rod mechanism from interfering with the normal use of other surrounding pipeline systems.
[0016] 2. Both ends of the four-bar linkage are fixed to the metal pipe by pins. The use of the pins provides a reliable rotation point, allowing the linkage to adjust its angle and position when necessary to adapt to the movement or deformation of the pipeline system, ensuring the dynamic response capability and mechanical elasticity of the entire structure. The middle position of the four-bar linkage is fixed to the metal ring sleeve by a pin, which not only strengthens the structural integrity of the entire four-bar linkage, but also helps maintain the S-shaped configuration of the metal hose to prevent excessive movement or deformation under high vibration conditions.

[0026] The distance between the parallel line of the first inflection point 12 along the length direction of the metal hose 1 and the horizontal line of the second inflection point 13 along the length direction of the metal hose 1 is smaller than the width of the connecting rod mechanism, so that the end of the connecting rod mechanism will not protrude from the position H of the horizontal line when contracting, thereby preventing the connecting rod mechanism from interfering with the normal use of other surrounding pipeline systems.

[0028] The metal ring sleeve 4 can be made of stainless steel to match the material properties of the metal hose 1 and enhance the overall corrosion resistance. The mesh sleeve 16 is made of steel wire braided material with good elasticity and toughness. Through precise welding technology, the metal ring sleeve 4, the mesh sleeve 16 and the metal pipe 11 are welded and fixed in a trinity to form a strong and sealed structure.
