This utility model relates to a temporary support device for roadways in mining engineering, belonging to the field of mining engineering technology. The temporary support device for roadways in mining engineering includes: a support mechanism, comprising a base, a mounting block, and a lifting plate; two sets of lifting components are provided on the upper surface of the base; a detachable mechanism, comprising a detachable plate, a connecting plate, and a connecting threaded rod; the connecting plate is fixedly disposed on both sides of the detachable plate, and the detachable plate is threadedly connected to the lifting plate via the connecting threaded rod; and an auxiliary mechanism, comprising a connecting block, an extension column, an auxiliary top plate, and a drive component that drives the auxiliary top plate to rise and fall to support the roadway. When the detachable plate adheres to the roadway, the drive component drives the extension column to rise, thereby driving the auxiliary top plate to support the roadway on both sides of the detachable plate. At this time, the lifting component drives the lifting plate to fall, thus supporting the roadway while simultaneously lowering the detachable plate, thereby preventing the entire arch on both sides of the detachable plate from being torn off during attempts to disassemble it.

This application relates to the field of display screen assembly technology, and in particular to a display screen assembly fixture. The display screen assembly fixture includes: a fixture body, a display screen placement slot for placing the display screen, and a pressure plate hinged to the fixture body for pressing and fixing the display screen. The pressure plate has clearances corresponding to the positions of the double-sided release film layers on the FPC of the display screen. The display screen assembly fixture of this application can avoid tearing the FPC when removing the release film.

The utility model discloses a multi-layer label type anti-counterfeit label which comprises a second base layer, a first base layer adheres to the top of the second base layer, an anti-counterfeit layer adheres to the top of the first base layer, a safe edge is arranged outside the first base layer, a through groove is formed in the middle of the safe edge, the first base layer is located in the through groove, and the anti-counterfeit layer adheres to the top of the first base layer. The edge of the first base layer is connected with the side wall of the through groove through a point breaking hole, a wear-resisting layer adheres to the top of the anti-fake layer, an antifouling layer adheres to the top of the wear-resisting layer, a containing groove is formed in the bottom of the protective edge, a groove is formed in the edge of the top of the second base layer, and when the first base layer is located in the through groove, the anti-fake layer is attached to the side wall of the through groove. The edge of the second base layer is moved into the containing groove, anti-fake marking can be conducted on the product through the anti-fake layer, then the protective edge is matched with the first base layer and the second base layer, the label can be prevented from being completely torn off from the product, and the anti-fake effect is improved.
