It is an object of the invention to provide a kind of U-bolt of high tautness, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, the present invention provides following technical scheme：A kind of U-bolt of high tautness, including straight bolt
Body and bending key, the top of described straight key is provided with screwed plug, and the side of described straight bolt is provided with bolt hole, described straight bolt
Inside be provided with alloy core, the inside of described alloy core is provided with Q345 strength steel, and the side of described Q345 strength steel is provided with carbon steel
Net, the bottom of described carbon steel net is provided with Q235 steel, and the side of described bending key is respectively equipped with symmetrical mild steel, described low-carbon (LC)
The bottom of steel is provided with Elastic Steel, and the side of described Elastic Steel is provided with nickel alloy support chip, and the side of described nickel alloy support chip sets
There is pad, the side of described pad is provided with pressure lock, and the bottom of described pressure lock is provided with rotation pearl, and the bottom of described rotation pearl sets
There is top flat.
Further, described straight key is fixedly connected by Elastic Steel with bending key.
Further, described Elastic Steel is fixedly connected by alloy core with screwed plug.
Further, described pressure lock is flexibly connected by rotating pearl with top flat.
Further, the side of described screwed plug is provided with magnet.
Compared with prior art, the invention has the beneficial effects as follows：The U-bolt of this kind high tautness, employs each material
The seamless applying casting of the bed of material, is unlikely to deform expansion, it is achieved that density of material is big, bending strength the drawbacks of prevented chance aquatic rust
Greatly, the feature that impact flexibility is strong, compressive strength is strong, elastic modelling quantity is big, tensile strength is big and heatproof is high, using the side of second pouring
Method, that is, when cast basis the bolt hole of reserved appropriate size it is achieved that the intensive properties of the U-bolt of this kind high tautness and steady
Qualitative, alloy core and Q345 strength steel can allow straight key bear up the stretching of bigger pressure it is achieved that this kind high tautness
U-bolt high-strength supportive, pad and pressure lock can meet Force principle and can preferably share a part of stress, realizes
The high tightness of the U-bolt of this kind high tautness.
