5results about How to "Will not affect the detection effect" patented technology

The utility model discloses a liquid sampling, metering and detecting device, which relates to the technical field of liquid sampling and metering and comprises a sampling tube and a liquid inlet tube, a piston is arranged in the sampling tube, and a connecting rod penetrating through the sampling tube is mounted at the top of the piston. When the liquid sampling, metering and detecting device is used, a pressing block can be extruded according to the sampling requirement of liquid, so that the pressing block extrudes a clamping block into a telescopic rod, at the moment, the clamping block does not limit the telescopic rod, then a telescopic spring jacks a lantern ring upwards through the telescopic rod, and the lantern ring does not extrude an arc-shaped block; when the liquid is transferred, the arc-shaped block is not extruded, namely, the movable rod penetrating through the middle of the connecting rod is not extruded, at the moment, the movable rod can be pushed downwards, so that the movable rod blocks the liquid inlet pipe through the rubber plug, the situation that the liquid in the sampling pipe leaks when the liquid is transferred can be avoided, and the subsequent liquid detection effect cannot be influenced.

The invention belongs to the technical field of emulsifying equipment, and particularly relates to vacuum emulsifying equipment for paste preparation. The central pipe is arranged at the central position in the container; the second ultrasonic ends are symmetrically arranged on the outer wall of the central pipe at equal intervals; the first ultrasonic generator is installed in front of the top of the container, the second ultrasonic generator is located behind the top of the container, the first ultrasonic generator and the second ultrasonic generator are connected, and the height and the orientation of the second ultrasonic end are adjusted through an adjusting assembly. The height and orientation of the side pipe are adjusted through the adjusting assembly, the height and orientation of the center pipe are adjusted through the movable assembly, the first ultrasonic end and the second ultrasonic end complete height and orientation changes, the emulsification uniformity effect is improved, and due to the fact that the first ultrasonic end and the second ultrasonic end are different in power, the vibration frequencies of the first ultrasonic end and the second ultrasonic end are different, and the emulsification uniformity is improved. And the first ultrasonic end and the second ultrasonic end are staggered, so that heat generated by ultrasonic waves is easier to diffuse.

This utility model proposes a high-speed rotary drying and testing device for cylinder heads, belonging to the field of drying and testing technology. It solves the problem in existing technologies that cannot detect the proper clamping of workpieces, easily leading to workpiece damage due to incomplete clamping or the risk of workpiece detachment during operation, posing a safety hazard. It includes a top high-speed rotating shaft, a positioning plate, a frame, a lifting plate, a spring-type triggering mechanism, and a waterproof proximity switch. The positioning plate is connected to the bottom of the top high-speed rotating shaft, which is mounted on the top of the frame. A waterproof proximity switch is installed on the side of the top high-speed rotating shaft and mounted on the frame. The spring-type triggering mechanism is mounted on the positioning plate, and the lifting plate is located below the positioning plate and installed in the middle of the frame. It is mainly used for high-speed rotary drying and testing of cylinder heads.

The utility model relates to the technical field of sampling devices, and discloses a water quality sampling device which comprises a sampling barrel, the top of the sampling barrel is fixedly connected with a hollow barrel, the inner side of the hollow barrel is fixedly connected with a telescopic rod, and the output end of the telescopic rod penetrates through the sampling barrel and is fixedly connected with a piston. Connecting rods are fixedly connected to the left side and the right side of the bottom of the piston, a baffle is fixedly connected to the bottom of each connecting rod, a sealing gasket is fixedly connected to the edge of the top of each baffle, and a groove is formed in the bottom of the sampling barrel. The sampling barrel is placed in water, the rotating rod is rotated to loosen the rope to a proper length, the telescopic rod is started to push the piston to the bottom of the sampling barrel, then the baffle is separated from the bottom of the sampling barrel, then the telescopic rod is started to pull the piston, water needing to be sampled is pumped into the sampling barrel, and meanwhile the sealing gasket is placed in the groove. And the sampling barrel is sealed, so that the water quality is prevented from being influenced by water flows at different depths.
