Oscillating arm mechanisms are equipped with, the control crank is connect by pin shaft B with oscillating arm mechanisms, the upper end of the oscillating arm mechanisms and throttle support frame
Bottom plate connection is combined with manipulation in the lower end of connection, the oscillating arm mechanisms.
Wherein, the oscillating arm mechanisms include swing arm, and the middle part of the swing arm is connect by pin shaft B with control crank, described
The upper end of swing arm is connected by the middle part of throttle tension spring and throttle support frame, and the lower end of the swing arm is combined by pin shaft C with manipulation
Bottom plate connection.
For the ease of remotely being controlled, the middle part of the swing arm combines bottom plate connection with manipulation by return spring.
In order to running at high speed and idling limits, on manipulation combination bottom plate and to be located at swing arm two sides right respectively
Swing arm top and middle part of swing arm is answered to be provided with high speed stop screw and idle stop screw.
For the ease of carrying out quenching operations, the bottom plate back side is combined in the manipulation and is arranged positioned at manipulation combination bottom plate top
Have and puts out firewire binding post.
By adopting the above-described technical solution, the utility model has smart structural design, easy to operate reliable, at low cost
Honest and clean advantage can effectively shorten the overall dimensions of control crank under the premise of security function using it, it is therefore prevented that manipulation hand
The appearance of the generation and control crank breakage problem interfered between handle and starting handle；Meanwhile spatial area is effectively reduced,
Convenient for the whole Transporting of gasoline engine.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is the positive structure schematic of the utility model；
Fig. 2 is the structure schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model
These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1: as shown in Figure 1, 2, a kind of gasoline engine throttle regulating mechanism, including carburetor 1, throttle support frame 2 and behaviour
One end of vertical handle 3, the throttle support frame 2 is connect by accelerator rod 4 with carburetor 1, and the other end of the throttle support frame 2 is set
It is equipped with throttle speed regulating handle 5, the regulating mechanism further includes manipulation combination bottom plate 6, and the control crank 3 is located at manipulation combination bottom plate
6 front and by pin shaft A7 with manipulation combine bottom plate 6 connection, it is described manipulate combine bottom plate 6 the back side be provided with swing arm machine
Structure, the control crank 3 are connect by pin shaft B8 with oscillating arm mechanisms, and the upper end of the oscillating arm mechanisms is connect with throttle support frame 2, institute
It states the lower end of oscillating arm mechanisms and manipulation is combined bottom plate 6 and connected.
Wherein, the oscillating arm mechanisms include swing arm 9, and the middle part of the swing arm 9 is connect by pin shaft B8 with control crank 3,
The upper end of the swing arm 9 is connect by throttle tension spring 10 with the middle part of throttle support frame 2, and the lower end of the swing arm 9 passes through pin shaft C11
Bottom plate 6 is combined with manipulation to connect.
In the present invention, by the setting of swing arm 9, the size of control crank 3 can be thus substantially reduced.
For the ease of remotely being controlled, the middle part of the swing arm 9 combines bottom plate connection with manipulation by return spring 12.
In order to running at high speed and idling limits, on manipulation combination bottom plate 6 and it is located at 9 two sides of swing arm and distinguishes
High speed stop screw 13 and idle stop screw 14 are provided in the middle part of corresponding 9 top of swing arm and swing arm 9.
For the ease of remotely controlling quenching operations, 6 back side of bottom plate is combined in the manipulation and is located on manipulation combination bottom plate 6
Portion, which is provided with, puts out firewire binding post 15.
The utility model works in this way: when control crank 3 rotates, control crank 3 drives swing arm 9 to rotate, swing arm 9
