The invention relates to a probe spring of a pipeline corrosion detector which detects the metal loss degree of a steel pipeline on line and relates to the technical fields of measuring magnetic variables, measuring the linear sizes of thickness and pipeline systems. The invention is characterized in that the probe spring is an elastic ring made by polyurethane. The probe spring is an elastic ring approximating to a triangle or a trapezium made by the polyurethane; a front bevel edge on the advancing direction of the detector is thinner than a back bevel edge; the middle upper part of the back bevel edge bends a little to the front; besides, the upper end and the lower side of the back level edge are provided with fixing holes. As the flexible elasticity, the elastic ring is applied on the probe spring of the pipeline corrosion detector to lead the detector to be stable when passing through a weld bead and lead the probe not to be impacted, thus prolonging the service life of the probe; besides, the elastic ring is hard to be damaged, has long service life, is easily processed and is an ideal probe spring.

The invention relates to a suction nozzle mechanism with a protection function. An R-axis sliding block is arranged on the right side of an R-axis extension shaft through an R-axis sliding rail and provided with a connecting block. A suction nozzle air cylinder is arranged on the upper portion of the connecting block through a suction nozzle air cylinder fixing frame. The lower end of the suction nozzle air cylinder is connected with a pressure head connecting block through a floating joint. The lower left portion of the R-axis extension shaft is provided with a pressure adjusting block. The lower end of the connecting block is connected with a weighing sensor through a weighing sensor seat. A connecting spring is connected between the pressure adjusting block and the weighing sensor. The lower end of the weighing sensor seat is provided with a suction nozzle seat. The lower end of the suction nozzle seat is provided with a suction nozzle. The lower end of the pressure head connection block is provided with a pressure head seat. The lower end of the pressing seat is provided with a pressure head. The right side of the suction nozzle seat is provided with a clamping jaw air cylinder through a clamping jaw air cylinder mounting frame. The lower end of the clamping jaw air cylinder is provided with a right clamping jaw jacket. The left side of the pressure head seat is provided with a left clamping jaw jacket through a left clamping jaw jacket fixing block. By the adoption of the suction nozzle mechanism, the suction nozzle can be protected, meanwhile the two edges of a part in the suction process are protected, and the small part is prevented from being impacted and dropping out.

The invention discloses an antitheft bicycle kiosk. The antitheft bicycle kiosk comprises a kiosk body; grooves and an antitheft lock are arranged on the kiosk body; the antitheft lock and the kiosk body are connected through a shaft; rubber cushions which are arranged inside the grooves can protect a bicycle from striking during parking and fetching. The antitheft bicycle kiosk has the advantages that space is saved and placing is in order and attractive in appearance due to the fact that the vehicle is parked upright; wheels and most bicycle bodies can be protected and the bicycle is protected from striking due to the fact that the wheels are fixed through the special grooves, an antitheft purpose is achieved and the parking is safe due to the fact that a special lock is added.

The invention discloses a grinding disc for grinding wall corner ground and a stone grinding machine, and belongs to the field of machinery. The grinding disc comprises a grinding disc body, and the grinding disc body is provided with an enhanced grinding block assembly for grinding the ground within the outer circumferential range of the grinding disc body in the outer circumferential direction; the enhanced grinding block assembly comprises an enhanced grinding block, a grinding block control air cylinder and an air cylinder installation base, the enhanced grinding block is installed at the movable end of the grinding block control air cylinder, and the grinding block control air cylinder is installed on the outer circumference of the grinding disc body through the air cylinder installation base; and a fixed sliding block is fixedly installed at the movable end of the grinding block control air cylinder, a vertically-arranged grinding block sliding rail is arranged on the outer circumference of the grinding disc body, and the fixed sliding block is installed on the grinding block sliding rail and can slide in the length direction of the grinding block sliding rail. The grinding disc has the beneficial effects that the enhanced grinding block assembly is installed outside the grinding disc body and specially used for grinding the ground below a wall corner, and the application range of grinding the ground through the grinding disc is effectively widened.
