Abstract

The utility model relates to a chain cutter. The utility model is composed of a convex seat, a pressing wheel, two side seats, two pressing nails and two springs which are arranged on a plane base and combined mutually. The pressing wheel is pivoted above the convex seat through an eccentric shaft; the two side seats are positioned on the both sides of the convex seat, and the pressing wheel is clamped by the two side seats. Through the springs, the two pressing nails are accommodated in shaft holes which are arranged on the end face of the convex seat. The upper ends of the pressing nails are contacted with the pressing wheel, and the bottom ends correspond to a tooth groove which is arranged on the end face of the convex seat. When the pressing wheel is controlled to rotate, the pressing wheel contacts and presses the two pressing nails because of the action of the eccentric shaft of the pressing wheel, and then, the two pressing nails are pressed downwards toward the tooth groove position of the end face of the convex seat. Then, two chain shafts on a chain which is sheathed on the tooth groove position are pushed out so that the chain is cut off.

Description

The chain cutter

The utility model belongs to hand off equipment, relates in particular to a kind of chain cutter.

Chain is widely used in various power and transmits on the facility, it is to utilize the chain rivet linking member series connection that majority is identical shaped to become seal ring set to be located between two gears, thereby reach the purpose of transmission power, in actual use, the chain rivet that can optionally pull down on the chain cuts off chain, increase or reduce linking member again, change chain length, cut off at present in the method for chain, modal is to cooperate the nail part to beat with instrument, and chain rivet is removed by beaing gravity, this mode of beaing is damaged chain easily, may cause chain rivet or linking member modification and can't re-use, in addition, in beaing, be easy to make the operator injured; Secondly also there is the Electronic Control of employing machinery to cut off the method for chain, as being the chain cutting machine of power source with motor and cylinder pressure, be provided with relevant power transmission shaft on this chain cutting machine, sprocket wheel, gear, runway, attached member such as display screen, by Electronic Control motor and cylinder pressure as power, cut off chain in order to the dismounting chain assemblies, this machinery needs to use more and complicated mechanical and electronic component, manufacturing cost improves relatively, owing to complex structure makes the huge heavy inconvenience displacement of body, assembly that is associated and action are many, easily cause operating trouble, increase the difficulty of maintenance, reduce service life.
