A substrate cassette device comprises a cassette frame for loading a substrate and a frame turnover mechanism for turning the cassette frame. The cassette frame comprises a substrate imbedding port; the cassette frame is provided with a plurality of substrate fixing mechanisms for fixing and supporting the substrate; the frame turnover mechanism and the cassette frame are fixedly connected for realizing turning of the substrate in the cassette frame in multiple angles. During a heating process of the glass substrate, the substrate cassette device provided by the invention can effectively improve the heating uniformity of the substrate through turning the glass substrate by multiple angles, and overcomes formation of gravity-induced depressions on the surface of the substrate in an existing static heating process of the substrate, so as to improve the flatness and size precision of the substrate.

A rotor includes a rotor core and a plurality of magnets. The magnets are fixed on an outer circumferential surface of the rotor core. The rotor further includes at least one protective tube. The protective tube includes a cover portion. An inner circumference of the cover portion is greater than a length of an envelope line formed by outer circumferential surfaces of the magnets and common tangents of the outer circumferential surfaces of adjacent magnets, and is less than a circumference of a circumscribed circle of the magnets. The cover portion covers the magnets in a circumferential direction, thereby guaranteeing the fixing strength of the magnets while also preventing the magnets from breaking.

The invention provides a moving mechanism which comprises vibration tables, a horizontal sliding table guide rail, a horizontal sliding table, vibration table guide rails and a foundation steel plate. The horizontal sliding table guide rail and the vibration table guide rails are pre-embedded in the foundation steel plate. The vibration tables move on the vibration table guide rails through vibration table moving wheels. The horizontal sliding table moves on the horizontal sliding table guide rail through a horizontal sliding table moving wheel. The cross sections of the horizontal sliding table guide rail and the vibration table guide rails are identical in structure, an inverted 'T'-shaped groove is machined in the center of each guide rail, and a 'V'-shaped opening is machined at the upper end of each inverted 'T'-shaped groove. The vibration table moving wheels and the horizontal sliding table moving wheel are identical in structure and are stepped cylinders, the center of each stepped cylinder is a protruded 'V'-shaped circular truncated cone, circular truncated cones are symmetrically distributed at the two ends of each 'V'-shaped circular truncated cone, and the included angle of the 'V'-shaped circular truncated cones is consistent with the included angle of the 'V'-shaped openings. The moving mechanism can achieve six kinds of vibration functions and is accurate in positioning and flexible and convenient in movement.

Compact lightweight gas insulated switchgear which assures sufficient electrode fixing strength equivalent to the fixing strength given by brazing and is structurally simple and enables efficient arc rotation with low operating energy. In the switchgear, a movable arcing contact is located on a movable element, opposite to a fixed arcing contact and electrically connected to, or disconnected from, the fixed arcing contact as the movable element moves. The movable arcing contact includes, in order from its tip opposite to the fixed arcing contact, a first electrode as a convex hollow coaxial cylindrical electrode, hollow coaxial cylindrical first spacer, and second electrode as a hollow coaxial cylindrical electrode and has electric conduction means to connect the first and second electrodes electrically through the first spacer. The first and second electrodes are fixed through the first spacer by a fixing member having higher resistivity than the first and second electrodes.

To provide a solar panel stand which has a small number of parts and can be easily installed. The stand for a solar panel comprises a first frame member 10 for supporting a solar panel, a second frame member 11 for supporting the first frame member 10 and extending in an orthogonal direction, and fixing members 13 fixed to the disposed foundation 12. The fixing member 13 is arranged in a pair so as to sandwich the second frame member 11 from both sides, and each fixing member 13 has a first fixing portion 29 fixed to the foundation 12 and a second fixing portion 28 that is fixed to the second frame member 11.

The invention discloses an ice skate blade quick replacement structure which comprises a knife rest, a limiting part, a rotary clamping hook, at least one elastic pressing device, an unlocking part, and a safety part; the knife rest comprises a front supporting shell, a rear supporting shell and a mounting groove for mounting a blade; the limiting part is arranged at the rear end of the mounting groove and used for fixing the rear end of the blade; the rotary clamping hook is hinged in the front supporting shell and is used for fixing the front end part of the blade; the at least one elastic pressing device is arranged in the front supporting shell and is used for enabling the rotary clamping hook to keep locking the blade; the unlocking part is arranged in the front supporting shell, oneend of the unlocking part is used for jacking and pressing the rotary clamping hook to enable the rotary clamping hook to be separated from the blade for unlocking, and the other end of the unlockingpart extends to the outer side of the front supporting shell; the safety part is used for limiting movement of the unlocking part, the blade replacing step is easy to operate, then the ice skate bladecan be rapidly replaced, and the ice skate blade replacing time can be greatly shortened.
