This utility model discloses a quick connector for curtain wall installation, relating to the field of curtain wall technology. The quick connector includes a wall body, with an embedded concave fixing member within the wall body. A connector is located at the top of the concave fixing member, and a keel is located at the top of the connector. As a further technical solution of this utility model, the connector has oblique tongues on both sides, and through grooves are formed inside the connectors on both sides of the oblique tongues. A compression spring is located inside the through grooves, and the compression springs fit against the oblique tongues on both sides, with the oblique tongues on both sides being movably connected to the connector through the compression springs. An extension block is integrally formed with the connector at the upper end of each of the oblique tongues on both sides. A through groove is formed on one side of the extension block, and an L-shaped fixing member is slidably connected by bolts in the through groove. A set of fixing holes is formed on both the side of the fixing member closest to the wall body and the side of the oblique tongue.

The present application relates to a kind of drawer switch anti-misoperation multi-functional safety warning clamping plate, the clamping plate main body is flat plate, the back of the flat plate is equipped with clamping arm, and it is composed of clamp with clamping arm, the front of the flat plate is provided with installation warning mark;Locking structure is installed on the clamp;The side or bottom edge of the flat plate is stop part, when using, the stop part is located on the advancing path of drawer switch.The design is reasonable, the structure is simple, suitable for drawer switch, not easy to fall off when using, and can prevent drawer switch misoperation (when misoperation, general force is not very big, will not cause clamp to loosen;And the design of locking structure further reduces the possibility of clamp loosening).

The utility model relates to the technical field of stage lamps, in particular to a damping locking structure which comprises a knob, a fixed seat, a damping fin, a rotating seat and a connecting piece, the connecting piece is respectively matched with the rotating seat, the damping fin, the fixed seat and the knob, and the connecting piece comprises a limiting section, a rotating section, a square shaft section and a screw section which are of an integrated structure. The rotary knob is pulled to enable the first spline tooth surface of the rotary seat to extrude the damping fin, the damping fin further extrudes the second spline tooth surface of the fixed seat, then the damping fin generates friction force with the first spline tooth surface and the second spline tooth surface respectively, the rotary knob and the threaded section are screwed tightly, the square shaft section is matched with the square shaft hole, and therefore the damping effect is achieved. The rotary seat is prevented from loosening in the direction opposite to the screwing direction of the rotary knob and the threaded section, the structure is simple, and the rotary seat can be applied to a stage lamp compact in structure.
