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.

The utility model relates to the technical field of circuit board processing, in particular to a graphite electroplating processing device capable of removing redundant graphite film layers, which comprises a connecting plate, a telescopic cylinder I, a pressing plate, a cutter and a driving component, the number of the connecting plates is at least two. Each connecting plate is fixedly connected with at least two first telescopic air cylinders. At least two pressing plates are jointly arranged among all the connecting plates, and the pressing plates are connected with the telescopic ends of the corresponding telescopic air cylinders I; all the connecting plates are jointly connected with a driving assembly; the driving assembly is connected with a cutter; when the circuit board is used, the graphene layers on the lower edge of the front side face and the lower edge of the rear side face of the circuit board body are pressed and limited through cooperation of the two pressing plates, the graphene layers are prevented from being torn down by the graphene layers on the thickness faces, and the protection function is achieved; the graphene layers on the lower portion of the front side face and the lower portion of the rear side face of the circuit board body are protected through the rubber pads; and the protection effect can be improved.

The utility model discloses a traction device for a bundling machine, and relates to the technical field of bundling machine traction. The traction device comprises a traction rod fixed to a tractor, a supporting plate is vertically fixed to the tail end of the traction rod, a reinforcing rod is fixed between the supporting plate and the traction rod, a connecting rod is arranged on one side of the supporting plate, and the tail end of the connecting rod is fixed to a bundling machine. The supporting plate is provided with a guiding assembly used for guiding the connecting rod to move in the height direction of the supporting plate. The supporting plate and the connecting rod can be connected through the steel wire rope, when the connecting rod and the supporting plate accidentally fall off, the steel wire rope can prevent a bundling machine fixed to one side of the connecting rod from being separated from the supporting plate and the traction rod, and the situation that a pipeline is pulled apart is avoided; and meanwhile, the steel wire rope can be kept in a tightened state during normal use through the packing assembly, and the conditions of winding and the like during height adjustment are prevented.

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.

The application discloses a boarding corridor docking device, which comprises a flexible channel, a docking assembly, a driving assembly and a footboard. The flexible channel is telescopic, and a first end of the flexible channel is adapted to be sealingly connected with a corridor. The docking assembly is connected to a second end of the flexible channel, and the docking assembly has a docking surface adapted to be connected with an outer wall of a spacecraft. The docking surface is provided with a suction member adapted to be fixed to the outer wall of the spacecraft. The driving assembly is adapted to be fixed to the corridor. The footboard is arranged on an inner bottom wall of the flexible channel, a first end of the footboard is connected to an output end of the driving assembly, and a second end of the footboard is connected to the docking assembly. The footboard is adapted to be driven by the driving assembly to drive the docking assembly to be connected with the outer wall of the spacecraft. The boarding corridor docking device can at least solve one of the problems of poor comfort, large design difficulty and poor sealing of the existing boarding docking equipment.
