Description
The application is Application No. 201210387914.9, the entitled hay mover with operation protection of innovation and creation
And its divisional application of the application for a patent for invention of safety switching mechanism, the applying date of original application is on October 15th, 2012.
Technical field
The present invention relates to a kind of hay mover and its safety guard, and in particular to a kind of hay mover with operation protection
And its safety switching mechanism.
Background technology
Hay mover is a kind of instrument for smooth lawn, and it is mainly realized to mistake by the motor band cutting blade of main body
The shearing of long blade of grass, in order to realize efficient mowing, the motor power of hay mover is bigger, therefore its people to operator
Body also has certain hidden danger safely, typically now makes operator avoid occurring far as possible from main body by longer handlebar stem
Danger, but hay mover convenient for collecting is to be able to, handlebar stem is often divided into scalable two sections, and this is possible to the handle in operation
Hand lever surprisingly shrinks, and causes user's both hands to be caused danger close to main body.
The content of the invention
, can be when unexpected shrink occurs for handle it is an object of the invention to provide one kind to solve the deficiencies in the prior art
The safety switching mechanism shut down in time and the hay mover with the safety switching mechanism.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
Suitable for the safety switching mechanism of slide trigger, including：Each other being capable of relative inner tube, pipe sleeve part and the installation slided
Safety switch assembly in pipe sleeve part；Inner tube is provided with safe shift structure, and safety switch assembly includes：Safety switch, inside
Safety switch is triggered when the safe shift structure of pipe departs from home and is resetted when safe shift structure returns to home
Trigger assembly.
Further, trigger assembly includes：What one end was fixedly connected with safety switch can be automatic under the effect of no external force
The contact flat spring of reset；The other end of contact flat spring is the free end for being contacted with inner tube.
Further, safe shift structure is for the holding tank for the free end for accommodating the contact flat spring under relaxation state.
Further, inner tube except in addition to the part of holding tank when it is slided to contact flat spring form compressing make its triggering pacify
Full switch, inner tube loosen contact flat spring when sliding into the home of holding tank alignment contact flat spring free end, and contact flat spring is multiple
Position makes safety switch be in non-triggering state；Contact flat spring is flexible.
Hay mover with operation protection, including：Main body and rotationally connected hollow one-level handlebar stem, main frame
Body is provided with motor and is electrically connected the controller for control, and it also includes：The foregoing peace for being applied to slide trigger
Standard-sized sheet shutting mechanism, pipe sleeve part are arranged on the end of one-level handlebar stem, inner tube by pipe sleeve part be embedded in inside one-level handlebar stem with
Composition be slidably connected, safety switch and controller are formed and electrically connected.
Further, the end of one-level handle is its free end.
The present invention is advantageous in that：By setting safety switching mechanism to ensure the safety of operator, occurring
When user's accident is close to main body, motor automatic shutdown, reduces and unexpected possibility occurs.
Brief description of the drawings
Fig. 1 is the structural representation of a preferred embodiment of the safety switching mechanism suitable for slide trigger of the present invention
Figure；
Fig. 2 is the structural representation of a preferred embodiment of the hay mover of the present invention；
Fig. 3 is the circuit block diagram of one preferred embodiment of hay mover of the present invention.
Embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
Shown in reference picture 1, the safety switching mechanism suitable for slide trigger of the invention mainly includes：Inner tube 1, pipe sleeve part
2 and safety switch assembly.Wherein, safety switch assembly includes：Safety switch 3 and the trigger assembly for triggering safety switch 3.
Safety switch 3 and trigger assembly are provided in inside pipe sleeve part 2.Generally speaking, the peace of pipe including trigger assembly effect is
Full shift structure triggers safety switch and resetted when safe shift structure returns to home when departing from home.
Embodiment shown in reference picture 1, as a kind of succinct technical scheme, trigger assembly includes：Contact flat spring 301,
One end of contact flat spring 301 forms with safety switch 3 and connected, and the other end is free end, when inner tube 1 is slided, the tube wall of inner tube 1
Contact flat spring 301 is formed and oppressed, it is triggered safety switch 3, contact flat spring 301 itself has certain elasticity, when inner tube 1
When slip makes holding tank 101 to the home as safe shift structure, contact flat spring 301 by external force due to not acted on
Reset, triggering is not formed to safety switch 3.Safe shift structure in inner tube 1 is for accommodating the contact bullet under relaxation state
The holding tank 101 of the free end of piece 301.
Shown in reference picture 2 and Fig. 3, hay mover of the invention includes：Main body 6, one-level handlebar stem 7 and this foregoing hair
Bright safety switching mechanism, wherein, main body 6 is provided with motor, the control circuit for controlling motor and blade etc., is to realize to mow
The major part of machine work energy, one-level handlebar stem 7 are rotatablely connected the first order as main expandable handle with main body 6, it
Inner hollow can accommodate the inner tube 1 in the safety switching mechanism of the present invention, actually inner tube 1 and the relative slip of pipe sleeve part 2
Connection, and inner tube 1 are slidably connected with one-level handlebar stem 7, and pipe sleeve part 2 is fixedly connected with realization, pipe sleeve part with one-level handlebar stem 7
2 are arranged on the end of one-level handlebar stem 7, and this termination refers to the free end of one-level handlebar stem 7, and inner tube 1 passes through pipe sleeve part 2
Form and be slidably connected therewith inside embedded one-level handlebar stem 7, the free end of inner tube 1 can set operating handle 8, safety switch with
Controller forms electrical connection, and controller is formed and electrically connected again with motor, so as to realize that safety switch can control the work of motor.
Shown in reference picture 2, when inner tube 1 is unexpected is retracted to one-level handlebar stem 7, user may be because of operating behaviour
Make handle 8 and get too close to main body 6 so as to cause danger, now safety switch 3 is triggered, motor shutdown, reduces use
The possibility that person causes danger.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for above-described embodiment, all to be obtained by the way of equivalent substitution or equivalent transformation
