5results about How to "Prevent snagging" patented technology

The utility model belongs to the technical field of ground mats, and particularly relates to an anti-snagging ground mat which comprises a bottom layer. The top of the bottom layer is provided with a surface layer through a middle layer; wherein the surface layer comprises a braid layer adhered to the top of the middle layer, and a protective layer is sprayed on the top of the braid layer; the braid layer comprises a gap filling assembly which is used for filling gaps of the main body to make the top of the main body smooth. By means of the design of the woven layer, fibers can be tightly attached together, the probability that the fibers are hooked up by the fibers is reduced, meanwhile, the protective layer is sprayed on the surface of the woven layer and is the PU coating, the surface of the ground mat is smoother, snagging is prevented, and meanwhile due to the fact that the protective layer has the waterproof effect, the ground mat is more comfortable to wear. Meanwhile, due to the design of the bottom layer, the ground mat has the anti-skid function, and meanwhile the anti-skid effect can be further improved through adsorption of the ground mat and the ground.

The utility model belongs to the technical field of enamelled wire production, and particularly relates to a novel enamelled wire active paying-off mechanism which comprises a rack, a fixed guide wheel, a movable guide wheel, an air cylinder, a speed reducer, a servo motor, a traction wheel and an encoder. The fixed guide wheel is installed on the left side of the machine frame, a cylinder body of the air cylinder is installed on the machine frame, a piston rod of the air cylinder faces downwards and is connected with a movable block, the movable guide wheel is installed on the movable block, the encoder is connected with the movable guide wheel, the servo motor is connected with the traction wheel through the speed reducer, and the traction wheel is connected with the servo motor through the speed reducer. And the servo motor and the speed reducer are mounted on the right side of the rack. By means of the mechanism, the pay-off speed can be effectively adjusted, wire laddering is prevented, and the product quality is improved.

The utility model discloses an air filter inner core subassembly relates to air filter element technical field. An air filter inner core subassembly includes: the outer layer metal support net, nanometer metal filter screen, inner layer metal support net that set up in proper order from outside to inside, the utility model has high strength, high breaking degree, high air permeability etc. advantage, second nanometer metal filter screen has good thermal stability, and it is more suitable for using under high temperature environment, and nanometer metal filter screen can take place elastic deformation under the airflow impact simultaneously, has good resilience, compares traditional paper filter core to avoid the fiber fracture problem of paper filter core, and nanometer metal filter screen compares paper filter core and will not because of humid etc. problem, and the problem of air permeability drop occurs, and the traditional paper filter core is in the case where air is humid, and moisture will cause paper filter core humid, causes dust and other foreign matters to adhere on paper filter core, and causes air permeability to drop, and then influence ventilation capacity.

The invention discloses a garment buttonholing machine with an anti-wrinkle function, and relates to the technical field of buttonholing machines, the garment buttonholing machine comprises a bottom plate and a buttonholing machine body arranged at the upper end of the bottom plate, and further comprises a workbench arranged at the upper end of the bottom plate; the partitioned dynamic air flotation assembly is arranged on the inner side of the workbench and comprises a base plate arranged in the workbench, a microwell plate is fixed to the upper end of the base plate, a machining opening is formed in the center of the plate face of the microwell plate, an air distribution cavity plate is fixed between the base plate and the microwell plate, and the machining opening is formed in the center of the plate face of the microwell plate. The space between the substrate and the microporous plate is divided into a plurality of independent air cavities by the air cavity dividing plates, and the plurality of independent air cavities are divided into a central operation air cavity, a peripheral stable air cavity and an edge auxiliary air cavity which are arranged from inside to outside. According to the device, the functions of non-contact fixing and unstressed conveying are achieved, extrusion wrinkles, stretching wrinkles and pushing wrinkles around buttonholes are effectively eradicated, and the problem of wrinkles generated when buttonholes are formed in high-grade clothes is fundamentally solved.

The utility model provides a lifting mechanism of a stage truss, and belongs to the technical field of stage equipment. The technical problems that steel wire ropes of lifting points on an existing truss are prone to mutual interference, and synchronism is poor are solved. A main guide piece is fixed above a crane of the lifting mechanism of the stage truss, an auxiliary guide piece is arranged above the truss, a steel wire rope is sequentially wound in a spiral groove of a winding drum, and an auxiliary guide wheel of the auxiliary guide piece is provided with an auxiliary guide groove. One end of the steel wire rope is fixedly connected with the winding drum, the other end of the steel wire rope sequentially penetrates through the main guide piece, the auxiliary guide piece and the auxiliary guide groove corresponding to the auxiliary guide piece and is fixedly connected with the truss, and all the auxiliary guide wheels are located in the same vertical plane. A plurality of steel wire ropes are simultaneously driven by the winding drum to be synchronously wound and unwound, and the synchronism is good; all the auxiliary guide wheels are located in the same vertical plane, and it is guaranteed that lifting points, connected with the steel wire rope, on the truss are located on the same straight line.
