Disclosed is a mounting structure for a galvanometer motor. The mounting structure includes a motor apparatus directly mounted on a platform, wherein at least one connection through hole running vertically from a top portion of a housing and extending to a bottom portion of the housing is molded on the housing, and the housing is provided with a connection post, wherein the connection post runs through the connection through hole and is fixedly connected to the platform. In this way, an additional mount is not needed, such that mounting cost is reduced, and mounting is accurate and reliable.

A quick-release fastener structure includes a body portion and an engaging portion. The body portion is fitted to a first object. The engaging portion is movably fitted to the body portion. The engaging portion has a head portion, a bar portion with an end connected to the head portion, and an engaging-connecting portion disposed at another end of the bar portion. The engaging-connecting portion is insertedly engaged with or separated from a second object. Therefore, the quick-release fastener structure operates by fitting the body portion to the first object and allowing the engaging portion to be engagedly connected to the second object or removed from the second object, such that the at least two objects are coupled together and separated repeatedly and quickly.

A fixing cover (12) configured to cover an exposed portion of a fixing (10), the fixing cover (12) comprising a filler (20) and gripping means (40).

A façade comprises a façade panel, a hanger and a fastener extending through the hanger into a blind hole provided at the façade panel. The fastener comprises a shaft defining a fastening direction and has a front face facing in the fastening direction for penetrating the façade panel and a back end facing in a direction opposite to the fastening direction, and a head arranged at the back end and having a bearing surface facing in the fastening direction for bearing on the hanger. The front face has an outer edge at an outer circumference of the shaft and a recess falling short in the fastening direction with respect to the outer edge.

An insert for the attachment of objects to composite or plastic panels consists of two parts, a retainer and an insert. The retainer has a through-hole and knurls on its perimeter for gripping the walls of a receiving hole in the composite or plastic panel. The insert has multiple self-clinching features at increasing diameters which when inserted into the retainer rigidly attach it to the retainer. The panel is rigidly clamped between opposite sides of the panel by an enlarged head of the retainer and an opposing flange on the insert. The self-clinching features of different diameter permit the device to be used with panels of different thickness and allow a large tolerance range. A plain or threaded stud can be substituted for the threaded hole of the insert. Both the retainer and the insert can be metallic.

A device for compensating of tolerances between a first component and a second component is described. The device may have an elastic centering arrangement which is provided for centering the device in a nominal position on the first component, which may be formed for this purpose.

A roof mount assembly mounts a structure to a roof haying a rafter and a substrate supported by the rafter. The roof mount assembly includes a piece of flashing positioned on the substrate. The flashing includes a first surface, a second surface opposite the first surface and an aperture extending through the flashing. A fastener extends through the flashing aperture. A bracket is connected to the flashing via the fastener, and the bracket is sized to support at least one roof mounted structure on the roof. A seal is positioned between the flashing aperture and the fastener. The seal is sized to form a water-tight seal with the aperture to inhibit flow of fluid through the aperture. The seal includes a first portion and a second portion, in which the first portion is positioned to abut the flashing first surface and the second portion is positioned to extend through the aperture.
