By pressing the pressing handle, the clamping plate is unfolded, which facilitates sequential limiting of the insertion tube bend, thereby reducing the contact between medical personnel and the insertion tube, and improving the safety of the disposable cholangioscope.

The utility model discloses a PU spiral pipe repairing mechanism which comprises a placing base, supporting blocks are arranged on the two sides of the top of the placing base, a rotating rod is rotationally arranged between the supporting blocks, one end of the rotating rod extends to the outer portion of the supporting blocks and is provided with a handle, and a winding pipe used for winding a PU spiral pipe is arranged outside the rotating rod. One end of a PU spiral pipe penetrates through a through hole in a supporting block, then the PU spiral pipe is wound outside a winding pipe, finally a pull rod is pulled to drive an extrusion block to move upwards, one end of the PU spiral pipe is placed in a U-shaped frame, then the pull rod is loosened, and the PU spiral pipe is wound outside the winding pipe. When the PU spiral pipe is wound, an extrusion block moves downwards under the action of a compression spring so as to extrude one end of the PU spiral pipe, at the moment, a handle is rotated to drive a winding pipe to rotate, and meanwhile, the PU spiral pipe outside the winding pipe is wound outside the winding pipe, so that the PU spiral pipe can be rapidly wound, and a complex winding procedure is avoided.

The utility model belongs to the field of winding mechanism, specifically is a kind of winding mechanism for steel wire braiding hydraulic rubber hose production, including adjusting assembly;The outside of adjusting assembly is connected with winding assembly;Adjusting assembly includes adjusting seat, and the left end of adjusting seat is fixedly connected with motor;By setting adjusting assembly, motor drives transmission shaft to rotate to drive bevel gear one, bevel gear two rotation, further drive two screw rods to rotate, two screw rods respectively drive two sliders to move to opposite direction, to can drive two groups of connecting plate opposite direction movement, adjust the interval of two groups of connecting plate can be adjusted the interval of two vice winding roller, adjust the relative position of vice winding roller and main winding roller, finally can according to the different specifications of steel wire braiding hydraulic rubber hose adjust the height of entire winding device, the height of adjustment can be wound, to can prevent the condition of loosening when winding thicker longer steel wire braiding hydraulic rubber hose.

The utility model relates to the technical field of gum dipping, and provides a carbon fiber automatic gum dipping roll-out device which comprises a bottom plate, a gum dipping box is fixedly installed on one side of the outer surface of the top of the bottom plate, two fixing plates are fixedly installed on one side of the top of the gum dipping box, and a U-shaped plate is fixedly installed on the other side of the outer surface of the top of the gum dipping box; a carbon fiber wire harness is introduced into the impregnation box through one guide roller, penetrates through the bottom of a wire pressing roller in the impregnation box and then penetrates through the position between the other guide roller and a smearing plate, the smearing plate is movably connected to the upper end of a U-shaped plate through two limiting rods, and two springs can drive the smearing plate to be adjusted according to the carbon fiber wire harness; according to the glue dipping device, the glue dipping box is arranged, so that the glue dipping box is better attached to the carbon fiber wire harness, secondary glue coating is conducted on the carbon fiber wire harness subjected to glue dipping, glue is more evenly attached to the outer surface of the carbon fiber wire harness, and the dripped glue falls into the collecting box and then is recycled into the glue dipping box through the backflow groove.

The utility model discloses a woven fabric breadth adjusting mechanism for an air jet loom, which comprises a bottom plate and a side support plate, a winding mechanism for winding woven fabric is fixedly mounted at the top of the side support plate, a breadth adjusting mechanism is arranged outside the winding mechanism, and the width adjusting mechanism is arranged on the side support plate. An auxiliary supporting mechanism for preventing the woven fabric from loosening is arranged between the two sets of side supporting plates, and one side of each side supporting plate is fixedly connected with a tensioning mechanism for tensioning the woven fabric. The winding mechanism can wind the woven cloth, the breadth adjusting mechanism is arranged outside the winding mechanism, so that the woven cloth with different widths can be positioned, and the auxiliary supporting mechanism can support and limit the bottom of the wound woven cloth, so that the woven cloth with different widths can be wound. In this way, the situation that the rolled woven cloth roll is loose can be prevented, the tensioning mechanism arranged after weaving is completed and before rolling can prevent the woven cloth from being loose in the rolling process, and the situation that the woven cloth is wrinkled in the rolling process is prevented.

The utility model discloses a plate radiator uncoiling and feeding device, and relates to the technical field of uncoiling and feeding, the plate radiator uncoiling and feeding device comprises a support frame, a support plate is fixedly mounted on the top surface of the support frame, a lifting mechanism in mirror image distribution is fixedly mounted on the top surface of the support frame and one side of the support plate, and a coil stock is movably mounted on one side of the lifting mechanism; the lifting mechanism is arranged, the threaded rod is matched with the sliding block to support the connecting rod to move, so that the connecting rod drives the material supporting rod to ascend, roll materials are further lifted, the feeding efficiency of the roll materials is improved, the labor intensity of workers is reduced, the labor intensity of workers is reduced, and the working efficiency of the workers is improved. The flattening mechanism is arranged, pressure can be applied to the outer surface of the roll material through the flattening mechanism, and therefore the situation that the roll material is loose is prevented, the machining effect of the roll material is improved, and the practicability of the flattening mechanism is improved.
