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.

The invention relates to a method for installing a piece of home automation equipment, and to a system for adjustably attaching a piece of home automation equipment to a wall, comprising at least two supports (1), each one comprising a support shaft and a holding device, and at least two adjustable attaching elements. The adjustable attaching elements each comprise a supporting frame (2) and a mechanical connection element (3). The adjustable attaching elements also comprise a locking device.

An anchor assembly for walls comprises a toggle member and a strap member pivotally mounted together, and a locking member. In a first position thereof, the toggle member is aligned with the strap member for insertion through the wall, whereas in a second position thereof, the toggle member extends behind the wall at an angle relative to the strap member which extends from the toggle member through the hole in the wall. The locking member is adapted to be displaced along the strap member until it engages the wall and to be locked on the strap member to prevent the locking member from displacing away from the toggle member. Therefore, the locking member and the toggle member are connected by the strap member and imprison the wall by abutting respectively the visible and hidden sides thereof. A fastener introduced through the locking member and the wall threadably engages an opening defined in the toggle member.

An anchor assembly for wallboard installation includes a toggle body that is elongated along a toggle body axis, the toggle body including opposed first and second arms and a slot between the first and second arms. A toggle nut is elongated along a toggle nut axis, the toggle nut mounted in the slot of the toggle body for pivot between an install orientation seated in the slot and an anchoring orientation protruding from the slot.

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.

An anchor for wallboard installation includes an anchor body elongated along an axis, the anchor body including a driving end, a wall boring end and an internal bore running from the driving end to an internal end short of a distal tip of the wall boring end. The anchor body includes a first frusto-conical body portion, a second frusto-conical body portion running from the first frusto-conical body portion to an annular groove and an end body portion running from the annular groove toward the distal tip.

An anchor assembly for wall installation includes a toggle body that is elongated along an axis, and a strap connected to and extending from the toggle body, wherein the strap includes a main segment that extends in a first direction away from an axis of the toggle body when the strap and toggle body are in an unstressed state, and the main segment is bendable down toward the toggle body such that the main segment extends in a second direction, where the second direction runs more closely to parallel with the axis than does the first direction. A locking sleeve mounted for movement along the strap toward the toggle body. The strap is substantially L-shaped and includes a small segment extending laterally relative to the main segment, wherein the small segment is seated within a recess on the toggle body.

Inexperienced users of conventional self-drilling drywall anchors may apply too much torque to its screw drive, even after the anchor has become fully bedded down in the drywall, under the mistaken impression that applying a greater torque will improve security of the anchor within the drywall. However, continuing to rotate the anchor after it has been fully inserted into the dry wall continues to rotate the anchor within the drywall and gouges out drywall material from around the anchor. Such gouging causes a cavity to form around the anchor, reducing its security within the wall. The present invention provides a self-drilling drywall anchor having a screw drive 16 that comprises a clutch configured to limit an amount of torque transmitted to the shank 5 by a tool engaged with the screw drive 16. In this way, a user may drive the anchor into a drywall, but over-tightening is prevented as the clutch limits the amount of torque transmitted to the shank 5, thereby preventing the external threads 7 on the shank from gouging out drywall material adjacent to the anchor and reducing the anchor's security within the drywall.

An injection molding apparatus including: a valve pin driven by an actuator, the valve pin extending axially through at least a portion of the channel length of the fluid flow channel, the fluid flow channel including a throat, downstream flow of the injection fluid being restricted by a bulb portion of the pin, the valve pin having an intermediate position where downstream flow of injection fluid is unrestricted and a fully downstream position where downstream flow of injection fluid is stopped at both the gate and at the throat, wherein the actuator is driven by a valve assembly comprised of a spool mechanically driven by first and second actuators or solenoids that each separately engage the spool at opposing axial ends to effect movement of the spool back and forth between the drive fluid flow positions.

A sleeve and pin combination for fastening of one or more screening media elements to a corresponding attachment socket of a screening equipment, a screening media element for co-operation with the sleeve and pin combination, an arrangement for fastening of one or more screening media elements to corresponding attachment sockets of a screening equipment, and a method for fastening of one or more screening media elements to corresponding attachment sockets of a screening equipment and also a screening equipment for separating solid materials according to size is provided.
