Description
Technical field
The utility model belongs to pull operation mechanism technical field, relates to a kind of pull operation mechanism and hangs spring regulating device.
Background technique
Known pull operation mechanism is mainly combined by hanging spring shaft, spring, arm-tie, lining, cushion cover, back-up ring, plain washer, spring washer, nut, cotter pin with extension spring assembly.Lining, bearing shell, arm-tie, back-up ring, plain washer, to be arranged on together with spring washer on hanging spring shaft, to load onto cotter pin with fastening nuts, reach by spring movement the object that mechanism closes a floodgate.But, when spring fitting is in mechanism, spring travel is determined by both sides arm-tie, namely the pulling force of spring is determined, because spring tension is along with spring access times are being decayed gradually, so that does not reach requirement to last pulling force, and spring cannot regulate, spring performance is reduced, affects mechanism working life, simultaneously spring fitting difficulty.
Model utility content
The purpose of this utility model is to provide a kind of pull operation mechanism to hang spring regulating device, solves the problem of existing pull operation mechanism spring fitting difficulty and usability deficiency.
The technological scheme that the utility model adopts is: a kind of pull operation mechanism hangs spring regulating device, and comprise the arm-tie being built in spring, arm-tie is provided with nut, nut is connected with bolt, also comprises hanging spring shaft, and hung bolt is on hanging spring shaft.
Feature of the present utility model is also:
The termination of hanging spring shaft is provided with anti-rotation baffle plate.
Anti-rotation baffle plate is fixed by screws on hanging spring shaft.
Arm-tie is fixed on hanging spring shaft by nut.
Hanging spring shaft is drilled with bolt through-hole, and bolt through-hole place is provided with plain washer.
Arm-tie is drilled with tapped hole.
Bolt is provided with spring washer.
The beneficial effects of the utility model are: a kind of pull operation mechanism of the utility model hangs spring regulating device, carries out free adjustment by bolt to the stroke of spring, and improve performance and extend spring mechanism working life, structure is simple, reliable performance.
Accompanying drawing explanation
