13884 results about "Self locking" patented technology

Self-locking devices are devices intended to arrest the fall of solo climbers who climb without partners. This device is used for back rope solo climbing for 'ground-up climbing' or 'top rope self belaying'. To date, several types of such self-locking devices have evolved.

Technical method for building self-insulating and energy-saving wall with Z-shaped energy-saving building blocks

In the invention, the same clad bricks are laid in the forward direction, and a positioning convex platform 2 and a longitudinal positioning convex platform 3 are used for realizing transverse and longitudinal self-locking positioning, thereby naturally ensuring the designed thickness and surface smoothness of the wall, forming a combined still air layer 12 which is 9mm to 10mm wide and vertical to the ground, and further blocking heat bridges in vertical bricklaying seams. The cavity of a 28-30mm-wide groove 4 in the horizontal bricklaying seam between two clad bricks is filled with a broken bridge insulation board 10 which is as wide as the groove and has a thickness of 15mm; the broken bridge insulation board 10 is used for sealing a long-strip groove still air layer 11 and the combined still air layer 12 and cutting off the heat bridges in the horizontal bricklaying seams; the exposed part of broken bridge insulation board with a height of 10mm, is used for controlling the coating thickness of anti-crack masonry mortar 13 to be even and uniform. When the self-insulating and energy-saving wall is built, Z-shaped energy-saving building blocks 1 of the upper clad bricks and the lower bricks are laid in a staggered manner so as to cut off heat bridges in vertical bricklaying seams. The structure of the invention, with a reasonable thickness, can satisfy the requirement of saving 50 percent of energy in various regions, or even higher requiremets without an internal or external insulating layer of walls. Simultaneously, the structure is easy to build and the formation of the block shape effectively ensures the thickness of walls and the smoothness of wall surfaces. The thermal insulation function of the still air layer with a thickness of 10mm to 12mm strengthens the heat insulation effect. The insulation boards (28-30mm wide and 15mm thick) between the two clad bricks is capable of cutting off the heat bridge effects.

Driving mechanism of dual-power automatic transfer switch

The invention relates to a driving mechanism of a dual-power automatic transfer switch. The driving mechanism mainly comprises a driving electromagnet assembly, a mounting bracket, a connecting plate, a push rod, a lever, an oscillating deck, a crank, a main switch rotating shaft, a connecting rod, a pin shaft, a rotating shaft, a first hinged shaft, a second hinged shaft, a connecting block, a shaft, a third hinged shaft and a fourth hinged shaft; the driving electromagnet assembly is composed of a magnet exciting coil, a dynamic iron core, a spring and a static iron core. The driving mechanism is characterized in that in the driving electromagnet assembly, linear motion in the horizontal direction of the dynamic iron core and the push rod is converted into linear motion of the pin shaft in the vertical direction through the oscillating deck, the lever, the connecting plate and the like, and linear motion of the pin shaft is converted into swing of the main switch rotating shaft around the axis through the connecting rod and the crank. Reciprocating swing of the main switch rotating shaft completes switching on and switching off actions of the whole switch. The oscillating deck plays a role in changing the motion direction. The lever plays a role in increasing thrust. A connecting rod crank mechanism plays a role in self-locking and preventing reversion.
