The utility model relates to the technical field of rubber joints, in particular to an anti-fatigue rubber joint which comprises joint ends, the joint ends are symmetrically distributed along the two ends, an integrally-formed joint center is arranged between the two joint ends, and built-in grooves are formed in the joint ends. Through the design of the joint center and the side flaps, the anti-fatigue and anti-deformation capacity of the rubber joint is remarkably enhanced, when the rubber joint needs to be bent, damage caused by bending can be reduced, the damping effect is achieved when objects at the two ends are extruded and impacted, the side flaps are annularly distributed outside the joint center and can be matched to be bent when the joint center is bent, and the anti-fatigue and anti-deformation capacity of the rubber joint is improved. In addition, the joint end is wrapped by the woven sleeve made of the aluminum alloy material, the situation that the joint end is extruded and deformed when connected with a pipe fitting or a rod piece is avoided, and the fatigue resistance of the rubber joint is further guaranteed.

A process for repairing the gable roof of a hip-and-gable building is characterized by the following steps: 1. Repairing the wooden base layer; 2. Applying protective plaster; 3. Applying two layers of hemp and six layers of plaster; 4. Applying three coats of pigment paint and one coat of varnish; 5. Making and installing a metal gable roof made of finely carved aluminum plate; 6. Fixing with round nails; 7. Restoring the glazed tile ridge and roof tiles; wherein, the method for making the metal gable roof includes: (1) splicing metal aluminum materials and polishing and finely carving the joints; (2) applying an epoxy fluorocarbon composite coating; the coating has a three-layer structure, consisting of a base layer, an intermediate layer and a cover layer, wherein the base layer is made of an epoxy resin type primer containing epoxy resin, epoxy modified filler and isocyanate curing agent, the intermediate layer is made of a composite two-component intermediate paint containing epoxy resin, fluorocarbon resin, polyamide resin and aliphatic polyamine curing agent, and the cover layer is prepared by a two-component fluorocarbon topcoat.

The invention discloses an electrode detection type motorcycle handlebar detection device and system, and relates to the field of motorcycle driving skill examination industry. The device comprises a control center mainboard and detection electrodes, the detection electrodes at least comprise a left handle electrode and a right handle electrode, the control center mainboard sends a high-voltage short-pulse coding signal to the left handle electrode, and whether an examinee correctly holds a handle is judged by monitoring the integrity of a return signal of the right handle electrode. The method has the advantages that the problems of poor interference resistance and high false alarm rate of an existing capacitive touch mode are solved through the special signal coding and pulse frequency modulation technology, meanwhile, the defects of blind areas, high cost and multi-vehicle mutual interference of an AI detection mode are overcome, human body non-inductive safety and offline independent high-reliability detection are achieved, the false alarm rate is smaller than or equal to 0.05%, and the method is suitable for popularization and application. The strict requirement of a driving test policy on the stability of the sensor is met, and the requirement for simultaneous use of multiple vehicles in test and training scenes is met.

The invention relates to the technical field of coatings, in particular to water-based two-component low-temperature stoving varnish for a photovoltaic frame and a preparation method of the water-based two-component low-temperature stoving varnish. The water-based two-component low-temperature stoving varnish for the photovoltaic frame comprises a component A and a component B, comprising the following raw materials in parts by weight: 50-60 parts of resin, 10-25 parts of functional filler, 4-10 parts of a solvent, 0.2-0.5 part of a defoaming agent, 0.1-0.3 part of a wetting agent, 0.5-1.5 parts of a dispersing agent, 0.2-0.5 part of a thickening agent and 10-15 parts of water, and the component B is isocyanate. The low-temperature baking varnish prepared by the invention has good adhesive force and excellent corrosion resistance, aging resistance and wear resistance.

The utility model relates to the technical field of grab handle electric picks, in particular to a low-vibration grab handle electric pick which comprises a low-vibration grab handle electric pick body and a grab handle fixedly installed at the bottom of the low-vibration grab handle electric pick body, and a vibration reduction mechanism used for reducing vibration when the grab handle is used is arranged on the outer surface of the grab handle. Reinforcing mechanisms are arranged at the two ends of the vibration reduction mechanism correspondingly. Through the arrangement of the vibration reduction rubber sleeve and the elastic metal hoop, when the vibration reduction rubber sleeve needs to be replaced, the elastic metal hoop can be taken down by reversely rotating the nut and taking down the nut and the threaded column through a tool, so that the vibration reduction rubber sleeve is detached and replaced, and the hand holding stability is prevented from being reduced; and the personal safety of workers can be protected.
