The shutter rotating device has the advantages that the shutter rotating device is good in wind resistance and rain resistance, capable of transmitting light, ventilating and draining water and convenient to rotate, open and close, and is suitable for tents or windows.

The invention relates to the technical field of filter elements, in particular to a mining filter element protective cover integrated with an NFC chip and a using method thereof.The mining filter element protective cover comprises a mask body and a filter element, and the filter element comprises a filter material layer and a supporting frame arranged on the periphery of the filter material layer; an electronic identification chip is arranged in a non-core filtering area on the edge of the filter material layer, and a microporous breathable film for packaging the electronic identification chip is arranged on the surface of the side, attached to the mouth and the nose, of the filter material layer; a visual identification code associated with the information of the electronic identification chip is arranged on the surface of the microporous breathable film; the visual identification code and the electronic identification chip jointly form a unique identity label of the filter element; through double identification of the electronic identification chip and the visual identification code, the anti-counterfeiting property and the tamper-proof property of the identity of the filter element are improved; the air permeability and filtering performance of the filter element are not influenced after the chip is integrated; by binding the filter element with the identity of the miner, individualized and traceable analysis of dust exposure data is realized, and real and continuous data is provided for occupational health management of the miner.

The utility model discloses a pair of breathable pull-ups with embedded printing layers, which belongs to the technical field of absorbent hygienic products and comprises a surface layer, an absorbent core and a bottom layer which are sequentially arranged from top to bottom, and two transverse sides of the surface layer are respectively provided with a leakage-proof partition edge extending between the bottom surface of the absorbent core and the top surface of the bottom layer. The bottom layer is sequentially provided with inner lining cloth, a leakage-proof bottom film and outer lining cloth from top to bottom, the outer lining cloth is sequentially composed of an inner spunbond layer, a melt-blown layer and an outer spunbond layer from top to bottom, a printing layer is arranged on the face, close to the outer spunbond layer, of the melt-blown layer, the leakage-proof bottom film is in a wave shape in the transverse direction, and a plurality of flow guide grooves extending in the longitudinal direction are formed in the side, close to the absorption core body, of the bottom layer. According to the utility model, the printing layer is arranged inside the outer lining cloth, so that the printing layer can have both higher definition and stronger adhesive force.

The utility model belongs to the technical field of tents or shutters, and relates to a shutter rotating device with an arc top, which comprises shutters and rotating pieces, a first U-shaped body with an inward opening is formed on one side of an arc-shaped part on each shutter, a second U-shaped body with a downward opening is formed on the other side of the arc-shaped part, the rotating pieces are arranged on the lower surfaces of the front end and the rear end of each arc-shaped part, and arc-shaped bodies are arranged on the upper surfaces of the front end and the rear end of each arc-shaped part. The surfaces, making contact with the arc-shaped part, of the rotating piece and the arc-shaped body are arc-shaped surfaces matched with each other, a bolt connecting part is arranged in the middle of the upper surface of the rotating piece, positioning columns are arranged on the two sides of the upper surface of the rotating piece, and through holes matched with the bolt connecting part and the positioning columns are formed in the shutters. Mounting holes and grooves matched with the bolt connecting parts and the positioning columns are formed in the lower surface of the arc-shaped body, a rotating shaft hinge hole is formed in the middle of the rotating part, and a linkage rod hinge hole is formed in the other side of the rotating part.

This utility model provides a moisture-proof and breathable valve bag, relating to the field of valve bag technology. It includes a valve bag with a base fixedly installed at the bottom of its outer surface. Two support frames are fixedly installed on both sides of the outer surface of the base. Two bidirectional screws are rotatably installed at the other ends of the four support frames. Four connecting blocks are fixedly installed on the upper side of the outer surface of the bidirectional screws. The four connecting blocks are threaded onto the outer surface of the two bidirectional screws. Two sliding rods are slidably arranged at the bottom of the four connecting blocks. The two ends of the two sliding rods are fixedly installed on the outer surface between the four support frames. A knob is fixedly installed at one end of each of the two bidirectional screws. Because the connecting blocks are limited by the bottom sliding rods, the rotation of the bidirectional screws can drive the four connecting blocks to move. Since the four connecting blocks are fixedly installed at the four corners of the valve bag, moving the connecting blocks to the sides can tighten the top of the valve bag, thereby closing the valve bag's inlet and preventing the valve bag from collapsing.

The utility model belongs to the technical field of tents or shutters, and relates to a shutter rotating device which comprises a shutter and a rotating piece fixedly connected with the shutter, one side of a flat plate part of the shutter is bent downwards and outwards to form an inclined inserting part, the other side of the flat plate part of the shutter is provided with a U-shaped body with an upward opening, a clamping part is formed on the outer side wall of the U-shaped body, and the clamping part is fixedly connected with the rotating piece. More than two first grooves which are longitudinally concave downwards are formed in the flat plate part at intervals, rotating pieces are symmetrically arranged at the front end and the rear end of the lower surface of the flat plate part of the louver, and at least one second groove matched with the first grooves is formed in the middle of the upper surface of each rotating piece; a clamping hook which is clamped on the clamping part and can contain the U-shaped body is arranged on one side of the upper surface of the rotating part, a rotating shaft mounting hole is formed in the middle of the rotating part, and a linkage rod hinging hole is formed in the side, away from the shutter and the rotating shaft mounting hole, of the rotating part. The shutter rotating device is suitable for tents or windows.
