Description
Technical field
The present invention relates to a kind of put-put field, in particular to a kind of cluster engine combination switch.
Background technique
With the raising of china's overall national strength and living standards of the people, with gasoline, diesel oil, natural gas, liquefied gas etc. as
The equipment of the put-put and its driving of fuel application it is also more and more extensive, as generator, grass trimmer, snowplough, it is micro- plough
Machine, water pump etc..The structure of put-put is relatively simple, and starting state, operating status and halted state are then by respective
Switch is to realize；In the prior art, the stacked switch of put-put and its equipment of driving hair includes choke flap switch, installation
Seat passes through transmission mechanism and fuel cock set on the fuel cock and flameout switch of mounting base, choke flap switch and flameout switch
It is linked；Fuel cock need to be only opened when starting engine, fuel cock drives flameout switch and choke by transmission mechanism
Door switch, so that simultaneously closing off choke flap switch and fine motion flameout switch, therefore operator only needs single stepping real
The closing of the opening, choke flap switch and flameout switch of existing fuel cock；Transmission mechanism includes shaft, and shaft can be by being located at peace
The knob control on seat is filled, is transported on sliding block concave-convex type track by spring in mounting base and steel ball when knob
Row, steel ball can be stuck in the groove of track when reaching gear point；But the structure is relative complex, track is relatively narrow, and when assembly is inevitable
There is certain deviation, and steel ball is easy to deviate from from track, make to switch out of control, effect when knob goes to gear point is also not very bright
Aobvious, position sense is not strong.Meanwhile existing stacked switch is fixed by mounting bracket, then with the knobs fit on control panel, because peace
Dress bracket and panel are independent two parts, potential difference occur with the knobs fit on panel after stacked switch installation, cause to assemble
Complex process, assembly effect are poor.
Therefore, it to solve the above problems, just needing to improve existing cluster engine combination switch, makes it easier to assemble
With maintenance, guarantee the validity of switch, reduce hazard rate, can effectively enhance the position sense of gear point.
Summary of the invention
In view of this, making it easier to assembly and maintenance the purpose of the present invention is to provide a kind of cluster engine combination switch, protect
The validity of switch is demonstrate,proved, hazard rate is reduced, can effectively enhance the position sense of gear point.

Axis, both ends form constraint to it on the direction perpendicular to laminated structure surface, then in the side perpendicular to laminated structure surface
There is certain elasticity upwards, which can form pretightning force；The cooperation direction of positioning protrusion and positioning groove is to cooperate
When positioning protrusion insertion positioning groove when direction, details are not described herein；Certainly, in shaft rotation process, for convex
It rises smoothly to deviate from out of positioning groove, then at least positioning protrusion and the recessed grain of positioning are arc in a rotational direction；Positioning groove
It can be directly arranged in shaft, also can be set in other component, such as turntable etc. by shaft driving rotation；The present embodiment
In, the positioning protrusion 521 of the Location resilient piece 52 and the positioning groove of turntable 53 are arc-shaped, convenient for being caught in for protrusion 521, and
Reduce the resistance that protrusion 521 is detached from groove.
In the present embodiment, the L-shaped bending in 52 both ends of Location resilient piece and L shape bending part are freely embeddable corresponding on pedestal
In L shape slit, i.e. Location resilient piece both ends are respectively perpendicular to that the bending of elastic slice surface is primary, and then first time bending part is secondary to both ends
Bending, that is, shape at L-shaped bending part forms corresponding and downward L shape slit in mounting base 1 and (refers to the axis along shaft up and down
To being subject to mounting base 1), the L shape bending part at elastic slice both ends makes elastic slice surface be parallel to shaft axial direction after being correspondingly embedded in；It is fixed
Elastic slice both ends after the installation in position are in restrained condition, and middle part is enough to guarantee to have to positioning protrusion direction arc-shaped bend
Pretightning force, structure is simple and practical, avoids falling off and long service life；Slit can be formed directly into mounting base 1, can pacified
Setting protrusion is set in protrusion on dress seat 1, can also in addition fixation member be formed, details are not described herein.
In the present embodiment, the positioning protrusion 521 from Location resilient piece 52 be bent to form for positioning groove push against with
Positioning is formed, positioning protrusion is directly formed by bending by Location resilient piece, structure is simple, saves cost of manufacture and tolerance is strong, with bullet
The deformation of piece itself is adapted, and has whole consistency, avoids uncoordinated caused elastic slice or the fracture of protrusion of deformation.
In the present embodiment, the L shape slit is formed in the fixed block 6 for being fixedly installed on mounting base 1, as shown, fixed
Block 6 can be integrally formed with mounting base 1, and reinforcing rib 7 is equipped in mounting base 1, and reinforcing rib connection fixing block 6 guarantees fixed block
Intensity, and integral strength and stability are improved by fixed block, reinforcing rib and mounting base 1 jointly.
In the present embodiment, the flameout switch 4 is set to shaft side, is equipped with radially with shaft driving cooperation
The flange 533 of protrusion is to switching with driving as shown, flange 533 can be configured according to the distance apart from flameout switch
It is quasi-；The flameout switch 4 is equipped with the opening and closing elastic slice 41 that control flameout switch 4 is opened and closed, and when the engine misses, shaft is rotated simultaneously
Driving flange, which resists opening and closing elastic slice, opens flameout switch 4；When shaft rotates, flange 533 is rotated with shaft, when flange resists
When opening and closing elastic slice, flameout switch 4 is opened, and engine misses, structure is simple, and operation is easy；Flange can be integrally formed with shaft,
It is also possible to be equipped in the circumferencial direction transmission of shaft in shaft, details are not described herein.
In the present embodiment, the choke flap switch includes swing arm 54 and drag-line 3, and the swing arm 54 can be turned by shaft drives edge

It contradicts, the opening and closing elastic slice 41 of flameout switch 4 is not contacted with the flange 533 of turntable 53, and flameout switch disconnects, and fuel cock is in and beats
Open state, with reference to Fig. 2, rotating plate 54 is rotated to the left, and choke pull 3 loosens, and carburetter choke is in own resilient strike-on next time
Open state, engine operates normally at this time.
When rotating knob to when stopping gear, with reference to Fig. 2, the positioning groove 53C and 52 convex of Location resilient piece of turntable 53
Rise 521 inconsistent, the opening and closing elastic slice 41 of flameout switch 4 is contacted with the flange 533 of turntable 53, and flameout switch connection, engine is put out
Fire, fuel cock are in close state, and rotating plate 54 rotates to Far Left, and choke pull 3 loosens, at carburetter choke switch
In opening state, engine misses at this time.
Inventive engine stacked switch is applied in the equipment of put-put and its driving, as generator, grass trimmer,
Snowplough, mini-tiller, water pump etc..
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
