Description
Technical field
The utility model relates to a kind of chain saw, relates in particular to a kind of hand-held electric chain saw.
Background technology
Electric chain saw is the very general a kind of electric tool of a kind of use, because the sawtooth of electric chain saw exposes, and has high rotational speed again, therefore the security of using is very important.Disclose a kind of electric chain saw as Chinese patent application 101590548, comprised casing and be installed in casing interior motor and brake gear thereof, described brake gear comprises: brake rim is set on the motor shaft, and together rotates with motor shaft; Brake ribbon is set on the outer rim of described brake rim, and the one end connects first brake units, and the other end connects second brake units.The brake gear of foregoing invention adopts two brake units, can tackle two kinds of situations of normal braking and snub respectively, after one of them brake units lost efficacy, can implement brake by another brake units, fully satisfied the requirement of electric chain saw safety in utilization aspect; And have braking rapidly, and easy and simple to handle, the characteristics that are active in one's movements.Its deficiency is the manufacturing cost height.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thus develop a kind of simple in structure, easy to operate, the electric chain saw brake gear of reliable in action.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of brake gear of electric chain saw, have brake wheel, brake ribbon, and it is characterized in that: include front brake and back brake; Described front brake is by the brake push rod, the brake hinge that the brake push rod links to each other, and with the brake ribbon that the brake hinge links to each other, the brake wheel that links to each other with brake ribbon composition, described brake hinge and extension spring are joined; Brake by the switch trigger in described back, the pull bar that links to each other with the switch trigger, and the shifting block that links to each other with pull bar, the brake hinge that links to each other with shifting block, with the brake ribbon that the brake hinge links to each other, the brake wheel that links to each other with brake ribbon is formed, and described brake hinge and extension spring are joined; Described brake hinge, brake ribbon, brake wheel extension spring are that forward and backward brake is shared.
The beneficial effects of the utility model are: braking mechanism is simple, reliable, and easy to use, reaction speed is fast, can effectively control the generation of casualty accident.
Description of drawings
Accompanying drawing 1 is a kind of back of the present utility model brake structure schematic diagram;
Accompanying drawing 2 is a kind of front brake structural representations of the present utility model;
Accompanying drawing 3 is that Fig. 1,2 brake wheel and brake ribbon concern left view.
Shown in the figure: 1 extension spring, 3 brake push rods, 4 brake hinges, 5 shifting blocks, 6 pull bars, 8 switches, 10 brake wheels, 11 brake ribbons.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
The brake gear of electric chain saw as shown in Figure 1-Figure 3 has front brake and back brake, and described front brake is by brake push rod 3, the brake hinge 4 that links to each other with the brake push rod, with the brake ribbon 11 that the brake hinge links to each other, the brake wheel 10 that links to each other with brake ribbon is formed, and described brake hinge 4 is connected with extension spring 1; Brake by switch trigger 8 in described back, the pull bar 6 that links to each other with the switch trigger, the shifting block 5 that links to each other with pull bar, the brake hinge 4 that links to each other with shifting block, with the brake ribbon 11 that the brake hinge links to each other, the brake wheel 10 that links to each other with brake ribbon is formed, and described brake hinge 4 is connected with extension spring 1; Described brake hinge, brake ribbon, brake wheel extension spring are that forward and backward brake is shared.
During work, rotation is positioned at the brake push rod 3 of fuselage front, and the brake push rod drives brake hinge 4, and under the pulling force of extension spring 1 drove, brake hinge 4 drove brake ribbon 11 and moves, and by brake ribbon locking brake wheel 10, thereby plays braking effect.
If rotation is positioned at the switch trigger 8 of fuselage back, drive shifting block 5 rotations by pull bar 6, brake hinge 4 drives brake ribbon 11 and moves under the effect of extension spring 1 pulling force, thus locking brake wheel 10, thus reach braking effect.
