At present, the door knife assembly of elevator forms primarily of door cutter base plate, door cutter connecting rod assembly, left and right door cutter and extension spring, wherein left and right door cutter is arranged on a cutter base plate by door cutter connecting rod assembly, extension spring 15 one end is fixed on a cutter base plate, and the other end is located at blade upper left (see Fig. 1).It adopts single extension spring stored energy, by the restoring force of the spring that is stretched, a blade for cutter system is opened, and extension spring restoring force action direction is close to elevator car door system door gate knife assembly inner rotation center.
This extension spring position is unreasonable, and the arm of force of the restoring force opposite house knife assembly effect of extension spring is too small, causes when extension spring restoring force is very large, and the overturning couple that extension spring acts on elevator car door system door gate knife assembly is still very little; Due to space constraint, extension spring diameter is restricted, and that can not do is very large, causes a knife assembly to open sensitive not.
Utility model content
For solving the problems of the technologies described above, we propose a kind of elevator car door system door gate knife assembly, are reached and make blade motion that is left and the blade right side more quick, react sensitiveer, shorten the object of system reaction time by the change of returning spring position.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of elevator car door system door gate knife assembly, comprise a cutter base plate, blade is left, blade is right, transmission center shaft one, transmission center shaft two, connecting rod one and connecting rod two, a described blade left side and the described blade right side are symmetricly set on described door cutter base plate side by side, the two is connected with connecting rod two by parallel connecting rod one, described connecting rod one is fixed on described door cutter base plate by described transmission center shaft one, described connecting rod two is fixed on described door cutter base plate by described transmission center shaft two, a described blade left side and described blade upper right are provided with returning spring one and returning spring two, wherein said returning spring one is obliquely installed, described returning spring two is horizontally disposed with.
Preferably, described returning spring one is located between described connecting rod one and described connecting rod two.
Preferably, described returning spring two is located at below described connecting rod two.
Preferably, described blade upper left is provided with hole one and hole three, blade upper right is provided with hole two and Kong Si, Kong Yi, hole two, hole three and Kong Sizhong are equipped with the bolt of negative thread and adaptation, the two ends of returning spring one hang on the bolt of hole one and Kong Erzhong, and the two ends of returning spring two hang on the bolt of hole three and Kong Sizhong.
The utility model is when elevator car door system door gate knife assembly agent structure is constant, the locus of reasonable Arrangement extension spring, the restoring force of extension spring is increased the arm of force of elevator car door system door gate knife assembly, thus the overturning couple making extension spring act on elevator car door system door gate knife assembly increases, the quantity of extension spring is made to be increased to two by one, make extension spring restoring force increase, thus make extension spring act on elevator car door system door gate knife assembly overturning couple increase; Make the motion of elevator car door system door gate knife assembly sensitiveer.
Compared with prior art, the utility model has the following advantages:
Constant in guarantee elevator car door system door gate knife assembly overall appearance structure, when installation dimension does not increase, under the prerequisite of the cost of not obvious increase spring, make blade motion that is left and the blade right side quicker, react sensitiveer, shorten the time of system response.
