    摘要: An anchor for hollow walls comprises a main body and an anchor member. The main body includes a proximal end adapted to be engaged by a rotatable tool to rotate the anchor about a longitudinal axis thereof and to cause it to gradually engage a wall, a distal end adapted to cut through the wall as the anchor is rotated, and a shank between the proximal and distal ends. The anchor member includes expandable wings and a body defining a hole, the expandable wings being in registry with respective slots defined in the shank and being displaceable between collapsed and expanded positions. A threaded fastener introduced in the anchor engages the body of the anchor member such that upon sufficient rotation of the fastener, the body of the anchor member retracts towards the proximal end thereby causing the expandable wings to extend outwardly through the slots behind the wall.

    摘要: The present invention discloses a guide pin, which comprises a base support layer (1) and a protective layer (2). The base support layer (1) is a rod-shaped structure. The protective layer (2) tightly wraps the surface of the base support layer (1). A manufacturing method for the guide pin made of various materials is also disclosed. The guide pin manufactured by the method of the present invention is not prone to bending or deformation and has good corrosion resistance and acid/alkaline resistance properties; it is wear resistant and has of extended service life; it is easy to be processed and is low in cost.

    摘要: An expansion screw structure contains an anchor for mating with a screw. The anchor includes a first segment and a second segment which have a central axis, and a shank. The anchor further includes a head which has a slot. The shank includes a first threaded section, multiple cutouts, a decreasingly conical tip, a second threaded section, a slit, a first support foot, a second support foot. The slit has a first part, a second part, and a third part. The second part has a first raised portion, the second part has a second raised portion, and the third part has a connection section and a thin coupling strap. The thin coupling strap has a first thickness, the connection section has a second thickness, and the first thickness of the coupling strap is ⅓ of the second thickness of the connection section.

    摘要: An anchor (910) for mounting to a hollow wall (W) made of friable material comprises a proximal flanged end (918) adapted to be engaged by a rotatable tool (B) to rotate the anchor (910) about a longitudinal axis (A) thereof and to cause is to gradually engage the wall (W). The anchor (910) also includes a distal end (912) adapted to cut through the wall (W) as the anchor (910) is rotated, and a shank (920) extending between the proximal and distal ends (918, 912). The shank (920) includes at least one expandable leg (924) that is in a collapsed position thereof when the anchor (910) is rotated to mount it to the wall (W) and that is located distally beyond a non visible surface of the wall (W) once the anchor (910) has been mounted to the wall and is in a first position thereof. The wall anchor (910) includes an outer thread (922) that securely engages the wall (W). A threaded fastener (B), e.g. a screw, is adapted to be introduced in the anchor (910) and to threadably engage the same distally of the leg (924) such that sufficient rotation of the threaded fastener (B) retracts the distal end (912) towards the proximal end (918) thereby causing the leg (924) to displace to a laterally expanded position thereof and to engage the non visible surface of the wall (W).

    摘要: A fastener for attaching together layers of a substrate. The fastener includes a slide body, a bolt, a conical spring, and a toggle having a pivot coupled with one end of the slide body. The conical spring is disposed over a shaft of the bolt and the shaft is engaged within the slide body. The slide body and toggle are inserted into an aperture through the layers of substrate in a first configuration until the conical spring contacts a front face of the layers of substrate. Compression of the conical spring against the front face advances the toggle a clearance length out of the aperture on a back face of the layers of a substrate such that the toggle can switch to a second configuration that prevents retraction through the aperture. Extension of the conical spring automatically engages the toggle with the back face of the substrate to prevent rotation of the slide body within the aperture.
