Abstract
The invention discloses a carburetor temperature control switch. The carburetor temperature control switch comprises a support, a rotating shaft, a rotating arm and a scroll spring. The rotating shaft is arranged on the support in a penetrating way, and the rotating shaft can rotate relative to the support. The internal end of the scroll spring and one end of the rotating shaft are fixed. The external end of the scroll spring is provided with a fixed convex part. The other end of the rotating shaft and one end of the rotating arm are fixed. The other end of the rotating arm is provided with a connecting hole which is used for fixing of a connecting rod and the connecting hole. Compared with a situation of environment temperature of 25 DEG C, the rotating angle of the rotating shaft is greater than 40 degrees when environment temperature is 65 DEG C. When environment temperature is 65 DEG C, the minimum torque output of the torque output end of the rotating arm is 0.5N.mm. According to the carburetor temperature control switch, the air door of a carburetor can be opened or closed according to temperature.
Description
Technical field
The present invention relates to Manufacturing Technology for Carburetors field, particularly relate to a kind of Carburetor temperature detect switch (TDS).
Background technique
Suitably closed portion suction port during engine cold-start, increase the gasoline concentration entering the mixed gas of cylinder, improve the startability of motor, chock plate should be opened completely after normal working of engine, not so motor can be caused not run well and to cause fuel consumption excessive because of mixed gas overrich.Opening or closing air door at present mainly relies on manual mode to open, and this mode operates inconvenience, and the degree opened or closed needs to rely on driver experience just can reach good effect, is very just for fresh driver.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of without the need to manually-operable, and Carburetor temperature detect switch (TDS) easy to use.
For solving the problem, the invention provides a kind of Carburetor temperature detect switch (TDS), described Carburetor temperature detect switch (TDS) comprises support, rotating shaft, pivoted arm and scrollwork spring, described rotating shaft wears on the bracket, and described rotating shaft can relatively described holder pivots, the inner of described scrollwork spring and one end of described rotating shaft are fixed, the outer end of described scrollwork spring is provided with fixing boss, the other end of described rotating shaft and one end of described pivoted arm are fixed, the other end of described pivoted arm is provided with for the attachment hole fixing with connecting rod, ambient temperature 65 DEG C time relative to ambient temperature 25 DEG C time, the angle that rotating shaft rotates is greater than 40 °, and ambient temperature is 65 DEG C time, pivoted arm torque output minimal torque exports as 0.5N.mm.
Further, described scrollwork spring is bimetal wind spring.
Further, described support is provided with fixed block, and described fixed block is provided with fixed hole.
Further, the crow flight distance between the shaft axis of the attachment hole on described pivoted arm and the shaft axis of described rotating shaft is 32mm.
Further, the one end described pivoted arm is connected with rotating shaft is provided with fixing blind hole.
Further, described pivoted arm is in falling " 7 " font.
Further, the cross section semicircular in shape of described lug boss.
Carburetor temperature detect switch (TDS) of the present invention utilizes scrollwork spring the conversion of engine temperature to be become angle change, produces moment of torsion simultaneously and is exported by rotating shaft, and pivoted arm drives connecting rod that the air door of its Carburetor is opened or closed.
Accompanying drawing explanation
