The invention discloses a method for preparing a macroporous PET film skeleton composite diaphragm. The PET film sold in the market can be used as the raw material for preparing the skeleton. Laser drilling is adopted, and the skeleton preparation process is simple and the cost is low. The size range of the PET film drilling is 0.03mm. 2 ‑20mm 2 The porosity range is 40%-90%. Not only are the pores large in size but also numerous in number. While retaining the high temperature resistance advantage of the PET skeleton, it eliminates the impact on the electrical performance of the battery cell. The PET skeleton composite ceramic diaphragm, combined with the advantages of the PET skeleton's high temperature resistance and the ceramic coating's strong puncture resistance, has greatly improved the safety performance of the battery cell. Conventional lithium iron phosphate batteries usually cannot pass 500℃ hot needle puncture and 150℃ / 3h hot box, but the PET skeleton composite ceramic diaphragm can easily pass such harsh safety tests.

The invention provides a catheter and a mesh basket, and relates to the technical field of medical instruments. The catheter comprises a sheath tube and an adapter, the adapter is provided with a first connecting part and a second connecting part, the first connecting part is provided with a first guide wire guide hole, the hole wall of the first guide wire guide hole is provided with a first side opening, the first guide wire guide hole is used for allowing a visible guide wire to penetrate through, and the first side opening penetrates through the outer wall of the first connecting part; the first side opening extends from the end face of one end of the first guide wire guide hole to the end face of the other end of the first guide wire guide hole, so that the hole wall of the first guide wire guide hole forms a non-closed structure, and the second connecting part is connected with the sheathing canal; wherein the width of the first side opening is smaller than the outer diameter of the visible guide wire, and at least one side of the two ends of the first side opening is of an elastic structure. According to the catheter, the visual guide wire can penetrate into the catheter without being limited by the near-end connector, the visual guide wire can be used for guiding the catheter to conduct intubation, and the working efficiency is high.

The present invention relates to the technical field of high-altitude cable measurement, and in particular to an environmentally friendly high-altitude cable measuring device; the device comprises a single main body consisting of an upper main body and a lower main body, wherein the front and rear main bodies are connected by a front and rear connecting rod mechanism to adapt to high-altitude cables with different curvatures, and a longitudinal transmission mechanism and a transverse transmission mechanism are arranged at the center of each main body, so that the device can detect cable damage and adapt to high-altitude cables with different diameters; the device can reasonably arrange existing sensors in the whole machine, enrich detection parameters and fully adapt to high-altitude cables with different curvatures.

The utility model provides a rocking desk and chair. The rocking desk and chair comprises a chair seat assembly, a backrest assembly, a base assembly, a front rocking assembly and a rear rocking assembly, the backrest assembly is connected to the rear swing assembly, the upper end of the rear swing assembly is rotationally connected to the rear end of the chair seat assembly and used for driving the rear end of the chair seat assembly to move, and the lower end of the rear swing assembly is rotationally connected to the base assembly; a damping mechanism is arranged in the base assembly, the fixed end is connected to the base assembly, and the movable end is connected to the rear swing assembly. When the seat assembly loses external force, the rear portion of the seat assembly moves upwards under the upward acting force of the rear swing assembly, the damping mechanism contracts, the rear swing assembly swings in the direction opposite to the contraction force, and then the front swing assembly is driven to swing in the same direction. The problems that people can pass through a traditional desk and chair only by standing up to give way, and students on the seats can easily pass through the back as long as the students swing forwards are solved.

The utility model discloses a municipal drainage pipe channel consolidation material removing device which comprises a collecting hopper, a shovel plate and a push rod, and a buffering mechanism is arranged between the shovel plate and the collecting hopper.
