The pouring quality and the construction safety are improved, and the good popularization value is achieved.

The invention discloses an interventional valve ring device and an interventional valve device. The interventional valve ring device and the interventional valve device can be used for mitral valve and tricuspid valve lesions. The interventional valve ring device is mainly composed of a valve ring, a valve ring conveying system, a fixing nail and a fixing nail conveying system. The interventional valve is mainly composed of a fixing support, a supporting support, a supporting support covering film and valve leaflets. The interventional valve ring and the interventional valve enter the heart through the interventional delivery system and can pass through the apex of the heart, the femoral vein, the jugular vein or the subclavian vein, the right atrium or the left atrium. The interventional valve is fixed in the interventional valve ring, and a minimally invasive, safe and effective treatment method can be provided for a patient.

This utility model discloses a sealing structure for the butt joint of concrete drainage pipes, relating to the field of drainage pipe connection technology. It includes a pipe, a threaded rod, a sealing plate, a connecting ring, a sealing gasket, a perforated slider, and grooves, rod grooves, and annular grooves formed on the pipe. The sealing plate is fitted onto the butt joint end of the pipe, with the inner sealing gasket conforming to the outer wall of the pipe. The perforated slider on the sealing gasket is embedded in the annular groove at the end of the pipe. The connecting ring is threadedly connected to the pipe and abuts against the sealing plate to fix the sealing assembly. The threaded rod passes through the perforated slider, can slide along the groove, and can be temporarily fixed by engaging the rod groove. When the two pipes are joined, the threaded rod locks in place to achieve a sealed connection. This structure, through multiple sealing mechanisms and a convenient fixing structure, solves the problems of poor sealing effect and inconvenient installation in traditional drainage pipe butt joints, improving the sealing performance and operational efficiency.

The utility model relates to a profiling LED bulb for an automobile, which comprises a lampshade, a lamp holder, a circuit board and a light-emitting component, the lampshade and the lamp holder are of a profiling structure of a C5W halogen bulb, the lampshade is of a split structure and comprises two shells with the same structure, semicircular connectors are arranged at two ends of each shell, the lamp holder is sleeved outside the connectors of the two shells, and the circuit board is connected with the light-emitting component. The circuit board is installed in the lampshade and comprises a body, end heads are arranged at the two ends of the body, a receding hole is formed in the surface of the body, and the light-emitting assembly is arranged in the receding hole. The LED signal lamp solves the technical problems that when a halogen bulb is replaced by an LED signal lamp, adaptability is poor, light distribution is uneven, and the light pattern effect is affected.
