8results about How to "Increase sliding resistance" patented technology

This utility model provides a feeding compensation device for a fully automatic film coating machine, including a supporting base plate placed on an external lifting platform for supporting materials, a plurality of placement slots equally spaced on the supporting base plate, a plurality of support rods with one end set on the supporting base plate within each placement slot and the other end located outside the placement slot, and a counterweight block set on the other end of each support rod. The length of the support rod is greater than the length of the placement slot, and the support rod is fitted with the placement slot with a clearance. By subsequently increasing the lifting stroke of the lifting platform, the lifting frequency of the lifting platform is reduced, thereby reducing the energy consumption of the lifting platform due to frequent start-stop.

This invention discloses a welding method for fabricating a three-dimensional reinforced steel / aluminum welded joint on a steel surface, belonging to the field of dissimilar metal welding technology. This invention employs laser selective melting to fabricate a three-dimensional geometric structure on the surface of a steel substrate, forming a surface with a high aspect ratio and high specific surface area. By using brazing or fusion brazing methods, the bonding area between the liquid aluminum and the steel plate and the three-dimensional geometric structure is greatly increased, effectively suppressing crack propagation and achieving a dual enhancement of the strength and toughness of the steel / aluminum dissimilar metal joint. This method increases the specific surface area of ​​the steel / aluminum joint interface, improving sliding resistance under external loads, while the three-dimensional geometric structure itself bears some of the stress. Simultaneously, the three-dimensional geometric interface structure can alleviate joint interface stress and improve stress distribution, which is beneficial for obtaining a welded joint with good performance.

On the basis of an original elastic bandage, a metal buckle plate is removed and replaced with a hook and loop fastener with J-shaped hooks distributed on one side, the J-shaped hooks can easily hook fluff of the bandage and warp and weft in the bandage, and the good fixing effect is achieved. And when the fastener is opened, the J-shaped hook can be stressed and deformed to be released as long as the fastener is torn back along the edge of the hook and loop fastener by a hand. And the whole elastic bandage can be conveniently removed or the tightness can be conveniently adjusted. The same hook-and-loop fasteners are respectively fixed on different side surfaces of two ends of the elastic bandage body, the double-sided tapes are respectively adhered on opposite side surfaces where the hook-and-loop fasteners are fixed, and anti-slip spots are coated on two side surfaces of the middle of the elastic bandage body. Due to the integrated central symmetry design, the bandage is not divided into the head and the tail, production and use are convenient, end-to-end reverse buckling connection of the bandages can be achieved, and the bandage has the advantages of being reliable in use, obvious in anti-skid performance, simplified in production process, low in cost and the like.

This utility model discloses a car interior handrail cover, including a rotating plate hinged to the top of the storage compartment. A connecting plate is slidably mounted on the surface of the rotating plate, and the surface of the connecting plate is detachably covered with a soft fabric. The rotating plate has two symmetrically distributed limiting grooves inside, with a slot between the two limiting grooves, and the slot communicating with the two limiting grooves. Two symmetrically distributed sliders are fixedly connected to the bottom of the connecting plate, and the sliders are slidably mounted within the limiting grooves. Two mutually movable baffles are provided inside the slot, with both ends of the baffles slidably connected to the inner wall of the slot. In this utility model, by operating the drive assembly, the distance between the two baffles decreases, reducing the degree of compression → reducing friction → reducing the sliding resistance of the sliders. At this time, the driver and passengers can easily push the connecting plate, improving operational convenience (especially suitable for one-handed adjustment scenarios).
