Description

Technical Field

[0001] The utility model relates to the technical field of mechanical strength detection, in particular to a carbon canister mechanical strength detection device. Background Art

[0002] A carbon canister is typically installed between the gasoline tank and the engine. Since gasoline is a volatile liquid, the fuel tank often fills with vapor at room temperature. The evaporative emission control system is designed to guide the vapor into combustion and prevent it from escaping into the atmosphere. The shape and installation location of a vehicle's carbon canister vary depending on the vehicle model. Some canisters are cylindrical, while others are rectangular. The material's mechanical strength, including tensile strength, compression, bending, shear, and impact resistance, requires mechanical strength testing to ensure safe use.

[0003] Patent CN117367991B proposes a mechanical strength testing device for plastic pallets. During an impact test, the first telescopic member contracts, extending the pressure plate assembly. The first telescopic member then extends, causing the pressure plate assembly to contract. The clamping claws insert into the gap in the pallet, clamping the pallet and securing it. Next, the pallet is lifted to a desired height using the spline of a lifting mechanism. The second telescopic member pushes a stopper into the interior of a slideway, securing the pallet. The spline of the lifting mechanism descends to the bottom, separating the pallet. Finally, the second telescopic member contracts, moving the stopper into the interior of a column. The pallet and pressure plate assembly then fall under gravity, impacting the ground. The pallet's impact strength is then tested using a strength testing system. During this process, the motor can be driven to rotate the pressure plate assembly and pallet to a certain angle, tilting the pallet. This initial tilted state impacts the ground, satisfying the impact strength test.

[0004] In the above scheme, the compressive strength test is performed by squeezing the object with a pressure plate. However, for a cylindrical carbon canister, it is difficult to make the force uniform by flat-plate squeezing, which affects the test result of the mechanical strength of the cylindrical carbon canister.

The present invention has a novel structure. The square or cylindrical carbon canister can be clamped and fixed through the clamping assembly to maintain the stability of the compressive strength test. At the same time, the upper pressure plate and the side pressure plate can apply forces in different directions to the square or cylindrical carbon canister respectively, and the compressive strength is tested by applying axial force to the cylindrical carbon canister, making the test more accurate.

[0006] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a carbon canister mechanical strength detection device, comprising a detection box, a supporting plate fixed inside the detection box, and a carbon canister body placed on the supporting plate, a clamping assembly provided on the surface of the supporting plate, the clamping assembly including a slide groove, two slide grooves symmetrically opened on the supporting plate, and two sliders symmetrically slidably connected inside the slide groove, a slide frame fixed on the outer surface of the slider, and a strap slidably inserted inside the slide frame, the strap can be bound to the surface of the carbon canister body, an upper pressure plate is provided on the top of the detection box, and side pressure plates are provided on both sides of the detection box, a cylinder is fixed on the top of the detection box, and the extended end of the cylinder is fixedly connected to the upper pressure plate, a movable groove is opened on the inner wall of the detection box, and the side pressure plates slide along the movable groove.
