Description
Technical Field
The utility model relates to a garden instrument specifically is a chain saw brake equipment.
Background
The chain saw is used as a garden electric tool, is mainly used for felling and wood making, and is widely applied to the fields of families, gardens and the like. The chain saw has the working principle that a power device drives a transmission mechanism, and the transmission mechanism drives staggered L-shaped blades to transversely move to cut. The brake device of the existing chain saw is a pure mechanical brake, and has a complex mechanical structure, heavy weight and large volume.
Disclosure of Invention
The utility model discloses a solve the problem that current chain saw brake equipment structure is complicated, weight is heavy, bulky, provide a chain saw brake equipment.
The utility model discloses an adopt following technical scheme to realize: the chain saw brake device comprises a machine shell and a motor, and comprises a machine shell rotating shaft fixed on the machine shell of the chain saw, wherein a front baffle is supported on the machine shell rotating shaft, a front baffle poking tooth is arranged on the left side of the lower portion of the front baffle, a front baffle poking sheet is arranged on the right side of the lower portion of the front baffle, a toggle switch is arranged on the left side of the front baffle poking tooth, a poking block is arranged on the upper portion of the toggle switch, the poking block is clamped in a groove of the front baffle poking tooth, a controller is arranged on the right upper portion of the motor, a front baffle limiting sheet is arranged on the left side of the front baffle, the toggle switch is a double-pole double-throw switch, six contacts including a contact a, a contact b, a contact c, a contact d, a contact e and a contact f are arranged on the lower portion of the toggle switch, the motor and the controller are respectively provided with three wiring lines of u, v phase lines and w phase lines of the, the u-phase line of the motor is connected to a contact d of the toggle switch, the u-phase line of the controller is connected to a contact b of the toggle switch, and a contact e and a contact f of the toggle switch are in short circuit.
When the chain saw is used, the front baffle is pushed forwards when the chain saw needs to be braked in the running process, the front baffle poking teeth drive the poking block to move the poking switch, the contact a and the contact e of the poking switch are connected, the contact b and the contact f are connected, and the contact e and the contact f are in short circuit, so that the v phase line and the u phase line of the controller are in short circuit, the motor stops rotating, and meanwhile, the front baffle poking piece is pressed on a motor rotating shaft to realize mechanical auxiliary braking. When the brake is not needed, the front baffle is pulled backwards, the front baffle shifting teeth drive the shifting block to enable the shifting block to act, the contact a and the contact c of the shifting switch are connected, the contact b and the contact d are connected, the three wires of the u-phase line, the v-phase line and the w-phase line of the motor and the controller are all connected, the front baffle shifting piece leaves the rotating shaft of the motor, and the motor operates normally.
The utility model has the advantages as follows: through reasonable structural design and corresponding control wiring design, the hardware brake of the electric device is realized. The utility model discloses an still utilize the structure to realize mechanical auxiliary brake when electrical part hardware brake, the reliability is high, the installation is simple, the processing cost is low, small, light in weight, brake are convenient.
