Abstract
The utility model relates to a bolt for doors and windows, which moves around a pivot, and the utility model is also matched with a spring. One end of a handle is connected with a sliding pin in shaft pin way, the certain position of the handle is connected with one end of a swing rod in shaft pin way, and the other end of the swing rod is connected with a fixed plate in the shaft pin way; the spring is arranged between the swing rod and the fixed plate. The connection of the all movable components of the utility model is that the handle is connected with the sliding pin in the shaft pin way, the handle is connected with the swing rod in the shaft pin way, and the swing rod is connected with the fixed plate in the shaft pin way. The utility model can move freely, and the force on the handle can be divided by the swing rod to achieve the purpose of labor saving.
Description
The utility model belongs to the fastening means that has around the latch of pivot activity, and latching action is particularly arranged.
A kind of thumb-latch of the prior art, an end of its handle is round, when this nose circle contacted with sliding pin, the crossed strip that is provided with on the compressible sliding pin was borrowed the bounce of spring and the similar action of cam of handle nose circle, and sliding pin is moved.This latch will directly compress spring with handle, very effort; When present single door and window is increasing, more and more heavier, when the sliding pin of being joined also more and more slightly or is more and more grown, moves the sliding pin of above-mentioned latch and just more require great effort gas.
The purpose of this utility model is to design a kind of labour-saving thumb-latch.
The utility model comprises fixed head, sliding pin and handle, handle one end is connected in the pivot pin mode with sliding pin, certain position on the handle is connected in the pivot pin mode with an end of fork, and the other end of fork also is connected in the mode of pivot pin with fixed head, between fork and the fixed head spring is housed.
Of the present utility model simple in structure, each movable part all connects in the mode of pivot pin, and activity freely, fork can remove the power branch of handle, divide and go the size of power to depend on that fork is connected the position of pivot pin on handle with handle, this position is far away more from the pivot pin that connects handle and sliding pin, and is so just laborsaving more.

Fig. 2: state diagram when sliding pin is packed up
Fig. 3: state diagram when sliding pin skids off
Present embodiment comprises fixed head 9, sliding pin 1 and handle 7, handle 7 one ends are connected by pivot pin 5 with sliding pin 1 one ends, handle 7 point midways are equipped with another pivot pin 6, pivot pin 6 also connects a fork 2, the other end of fork 2 is connected with fixed head 9 by a pivot pin 4 again, between fork 2 and the fixed head 9 spring 3 is housed.One grade of axle 8 is set again, sliding pin 1 is smoothly moved between shelves axle 8 and fixed head 9, can not produce certain oblique angle with handle 7 rotations.See figures.1.and.2, handle 7 is upwards lifted, sliding pin 1 moves down, fork 2 stretches out forward and compresses spring 3 simultaneously, surpass 90 when spending when handle 7 upwards lifts angle, spring 3 restores to the original state, and drives handle 7 again and continues upwards to turn over 90 degree, sliding pin 1 is moved down again, reach mobile maximum position; Equally, with reference to Fig. 3, handle 7 is rotated down, sliding pin 1 moves up, and fork 2 stretches out forward and compresses spring 3 simultaneously, surpasses 90 when spending when handle 7 is rotated down angle, spring 3 restores to the original state, drive handle 7 again and continue to turn over 90 degree downwards, sliding pin 1 is moved up again, return to position shown in Figure 2.
