  • Optimized thread profile for joining composite materials
    Patent number: 11204057
    Abstract: An optimized thread profile (140) for joining composite materials is presented. This thread profile (140) maintains a certain material strength when used as part of a composite threaded joint (101). The thread profile (140) comprises a repeating pattern of four components: a crest region (150), a first flank (162), a root region (170) and a second flank (164). The thread profile (140) is symmetrical, that is, the dimensions of the four components do not change throughout the length of the thread profile. The crest (152) has a flat profile and the root (172) has a rounded profile. When a shaft (120) is affixed to a joining shaft (110) using this optimized thread profile (140), the flat profiles of the crest (152) of the shaft (120) and corresponding rounded profiles of the root (172) of the joining shaft (110) create a gap to accommodate a substance such as an adhesive or a lubricant.

  • Quick fastening screw
    Patent number: 11199214
    Abstract: A quick fastening screw includes a head, a shank with spirally-disposed thread convolutions, and a drilling portion. Each thread convolution has at least three flank sections and at least three arc sections each formed between any two adjacent flank sections. Two ends of each arc section and the flank sections adjacent to the arc section are respectively intersected to thereby form two joints. Between the two joints is formed a curved cutting portion which forms a radian not more than a quarter of a maximum thread radius so that each curved cutting portion becomes sharp to cut quickly, speed up a screwing operation, decrease the friction between the thread convolutions and a workpiece, and reduce the resistance and torque. The non-circular thread convolutions also receive cut debris efficiently and prevent the cracking of the workpiece caused by the undue accumulation of the debris.

  • Fittable and releasable fastener
    Patent number: 11162524
    Abstract: A fittable and releasable fastener includes a head which has a fitted and released portion and a fastening portion; and a fitting and releasing piece which has a fitting and releasing portion. Accordingly, when the fitting and releasing portion fits to the fitted and released portion, an external turning force is applied to the fitting and releasing piece or the head to make the fastening portion combine with at least one object. After the fastening portion is combined with the object, the fitting and releasing portion would release the fitted and released portion to limit the force or the force interval applied on the fastening portion for preventing excessively locking if the force is continuously applied.

  • Easily removeable push-on spring nut
    Patent number: 11149775
    Abstract: A fastener is installed by applying an axial pressing force onto a mating component such as a round pin or a square tab. The fastener includes spring arms formed by bent tabs which deflect when pressed onto and grip the pin or other mating component between jaws of the arms making the fastener resistant to being pulled off. Downward facing fingers located around the periphery of the fastener flex when they come into contact with another portion of the mating component. This creates a residual clamp load between the fastener and the component. The fastener can easily be removed using a tool similar to snap ring pliers or needle nose pliers. Two holes on opposite sides of the fastener allow the part to be squeezed and deformed into an oval shape. This action disengages the arms and allows the fastener to slide off the mating component without resistance.

  • Wood screw
    Patent number: 11137012
    Abstract: A wood screw that includes a head and a shank is revealed. The shank is formed by a main shank portion and a tapered portion whose diameter is smaller than that of the main shank portion, both provided with a locking thread. A plurality of drilling units, whose outside diameter of the drilling unit is smaller than that of the locking thread, is disposed on the tapered portion. The drilling units first destroy workpiece material corresponding to the main shank portion so that the workpiece material becomes loose and the resistance of the locking thread of the main shank portion is reduced. Thereby the wood screw is screwed into the workpiece more smoothly. Moreover, an internal thread segment whose thread depth matches that of the locking thread of the main shank portion is formed so that the wood screw and the workpiece are fastened more firmly.
