摘要:
A latch (10) includes a base (12), a drive shaft (100) and cam (102), and a handle (110) attached pivotally to the drive shaft (100). The handle (110) is moveable between a closed position, a pop-up position, and an open position. A slide plate (24) is attached slidably to the base (12) and engaged with the cam (102). A swivel arm (52) is attached pivotally to the base (12) and the slide plate (24). A bolt assembly (66) is attached to the swivel arm (52), and a plunger (32) is mounted within the base (12). In its closed position, the handle (110) engages the plunger (32) to engage a switch (36) and the bolt assembly (66) engages a structure. In the handle's (110) pop-up position, the plunger (32) moves to a retracted position and disengages the switch (36). When the handle (1 10) is moved to the open position, the drive shaft (100) and cam (102) are rotated so that the slide plate (24) slides and the swivel arm (52) pivots to swing the bolt assembly (66) away from the structure.
摘要:
A thermohygrostat-type air conditioner with means for controlling evaporation temperature is characterized in that a temperature detector (72) is mounted on a return pipe between an evaporator (31,32) and a compressor (21,22) for detecting an existing temperature of the coiled return pipe from time to time. The detected temperature value is sent to a temperature controller (71) adapted to control operation of the compressor, so that the temperature controller (71) may regulate a rotary speed of the compressor (21,22) based on the existing temperature of the coiled return pipe and thereby maintains the return pipe at a preset temperature. In this manner, an evaporation temperature of a cooling coil pipe may be effectively controlled, and a stable humidity may be maintained in air conditioning with a low-cost and high-efficient apparatus.
