Abstract
The utility model discloses a braking structure of an electrical mower. The braking structure of the electrical mower comprises a base seat. A motor is fixed on the base seat which is connected with an output shaft in a rotating mode. The output shaft is provided with a belt wheel and achieves transmission with the motor through a belt. A braking plate is arranged on the upper portion of the belt wheel. A braking fixed plate is fixed on the base seat. The braking fixed plate is provided with a braking rod which is connected through a rivet and can flexibly rotate. The braking rod is provided with a friction plate. The friction plate and the braking plate on the belt wheel are tensioned through a braking retracting spring which acts on the braking fixed plate and the braking plate. A start pull rod and the braking rod are connected through a dragline rod, during the process that the start pull rod starts a machine, the dragline rod drives the braking rod to rotate so that the friction plate and the braking plate are separated, and the braking retracting spring accumulates elasticity. After the start pull rod is released, the belt wheel loses motive power, the braking retracting spring releases the elasticity, and accordingly the friction plate tensions the braking plate, and a braking function is achieved. The braking structure of the electrical mower is simple in structure, convenient to assemble, stable and reliable in performance and low in cost.
Description
Technical field
The utility model relates to the electric motor mower brake.
Background technology
Power-operated mower is a kind of gardens electric tool commonly used,, drives the main shaft that blade is housed by drive mechanisms such as belt or gears and carries out operation as driving with motor.If need in the operation process to shut down, at first cut off the electricity supply, but blade still can run up a period of time under effect of inertia, there is potential safety hazard, just need a brake gear control its motion for this reason, avoid causing personal injury.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of simple in structure, easy to assembly, stable and reliable for performance, low power-operated mower brake structure of holding concurrently of cost that has.For solving the problems of the technologies described above, the present invention adopts following technical scheme: the power-operated mower brake structure, comprise pedestal, fix a motor on the pedestal and be rotationally connected an output shaft, output shaft is provided with between a belt pulley and the motor and passes through belt transmission, it is characterized in that: fix a keep plate above the described belt pulley, fix a braking fixed head on the pedestal, the braking fixed head is provided with a brake bar, connect by rivet, can flexible rotating, brake bar is provided with friction plate, makes keep plate tensioning on friction plate and the belt wheel by acting on brake retracting spring on braking fixed head and the brake bar, starting between pull bar and the brake bar with a drag-line connection, in the process that the startup pull bar starts the machine, drag-line drives brake bar and rotates, and friction plate is separated with keep plate, brake retracting spring this moment is elongated, make brake retracting spring gather elastic force, after starting pull bar release, belt pulley runs out of steam, brake retracting spring discharges elastic force, make friction plate tensioning keep plate, belt pulley is stopped operating, realize brake function.
As preferably, described keep plate is an annular steel plate, and is positioned at above the belt pulley.
As preferably, fix a braking fixed head on the described pedestal, the braking fixed head is provided with a brake bar, connect by rivet, can flexible rotating, brake bar is provided with friction plate, makes keep plate tensioning on friction plate and the belt wheel by acting on brake retracting spring on braking fixed head and the brake bar.
As preferably, it is flexible that described drag-line is, and two ends act on respectively and start pull bar and arrestment mechanism.
Be equipped with a brake retracting spring between the utility model braking fixed head and the brake bar, and friction plate above certain pulling force tensioning brake bar arranged, this tensile force is so that after machine runs out of steam, can blade be stopped operating, brake bar can be with respect to rotating because deciding plate, after startup pull bar drive drag-line moves, drag-line also drives brake bar and rotates, and friction plate is separated with keep plate, and brake retracting spring is elongated, gather elastic force, after starting pull bar release, belt pulley runs out of steam, and brake retracting spring discharges elastic force, make friction plate tensioning keep plate, belt pulley is stopped operating.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model (braking state);
Fig. 2 is the utility model friction structure schematic diagram (braking state);
Fig. 3 is the utility model friction structure schematic diagram (duty);
