Fig. 2 is a power wheel structural principle schematic perspective view among Fig. 1.

Embodiment

As seen from Figure 1, the utility model comprises box type substructure 1 and side's fixed thereon board 2, and reducer casing 11 is housed on

board

2, and 10 rotating shafts are connected the input shaft of reducer casing 11 with motor, on its output shaft 9 power wheel 8 are housed; Wherein on the excentric shaft of power wheel 8, be rotationally connected respectively lock core connecting rod 3 and wheel connecting rod 7, an end of lock core connecting rod 3 other ends and lock core rocker arm 4 is rotationally connected, and the other end of lock core rocker arm 4 is fixedlyed connected with the lock core runner 13 in the lock body to be detected 12; One end of wheel connecting rod 7 other ends and wheel rocker arm 5 is rotationally connected, the cubic bar on wheel rocker arm 5 other ends insert in the core-inset type lock body 12 in the hand gear 14, and fixedly connected; Lock body 12 lateral surfaces are fixed on the vertical rack 6, and vertical rack 6 is positioned at power wheel 8 one sides, and the fixedly workplace of lock body and the axis normal of power wheel 8, and fixedly connected with board 2.

The principle of work of the utility model lock body durability-testing machines is: motor 10 rotates after reducer casing 11 speed changes, driving power wheel 8 by output shaft 9 slowly runs, drive wheel rocker arm 5 around hand gear 14 is swung up and down by the wheel connecting rod on the excentric shaft of power wheel 87, thereby drive the oblique tongue that is connected with thumb wheel 14 in the lock body 12 15 and make stretching motion, promptly open Door by Hand or close the door along rectilinear direction.Simultaneously, the lock core connecting rod 3 on the excentric shaft drives lock core rocker arm 4 towards other direction and swings up and down around lock core runner 13, makes stretching motion thereby drive the square tongue that is connected with runner 13 in the lock body 12 16 along rectilinear direction, promptly opens the door or locks a door with key.

From Fig. 2 as seen, power wheel 8 is the two-wheel structure of " H " type of being connected as a single entity, and rolling bearing 17 off-centre are installed between the two-wheel, and the excircle of bearing 17 is higher than the excircle of power wheel 8, and promptly bearing 17 is outstanding; On board 2, also be provided with horizontal support 18, and horizontal support 18 is positioned at the opposite side of power wheel 8, on horizontal support 18, fix another lock body 12 ', this lock body 12 ' in the tiltedly inclined-plane of tongue 15 and the cylindrical contact matching of rolling bearing 17, be that power wheel 8 is combined into a cam with rolling bearing 17, the inclined-plane generation primary collision of a moving week of revolution and oblique tongue 15, thus simulate the oblique tonguing of bump of closing the door, thereby finish oblique tongue is done gravity impact shear action test.On the lateral surface of power wheel 8 magnet 19 is housed also simultaneously, when power wheel 8 rotates, cooperate and finish tally function with the tongue tube under being contained in board 2, and by the flexible number of times that is contained in the numeric display unit side of the reading tongue 16 on the box type substructure 1 and the tiltedly flexible number of times or the bump number of times of tongue 15.

Embodiment recited above is described preferred implementation of the present utility model, is not that design of the present utility model and scope are limited.The content that the utility model is asked for protection all is documented in claims.
