Abstract
The invention discloses a chain saw speed regulating structure which comprises a shell; and a speed regulating assembly is arranged on the shell. The chain saw speed regulating structure changes the output power of a chain saw motor by changing resistors connected with a speed regulating module in series, and finally changes the output speed of a chain saw; moreover, the resistors connected in series do not have gears; therefore, stepless speed change can be realized.
Description
Technical field
The present invention relates to the chain saw structure, particularly a kind of chain saw speed regulating structure.
Background technology
Existing most chain saws do not possess speed-regulating function, can only under rated power, carry out work with specific rotation speeds, timber at differing texture, degree of wear difference to the chain of chain saw, such as on the harder timber of speciality, cutting, may need chain saw to cut, prevent that chain from crumbling even rupture with lower speed.
Summary of the invention
Problem to be solved by this invention just provides a kind of chain saw speed regulating structure, and is simple in structure, makes chain saw possess the stepless time adjustment function, adapts to the cutting work of various differing texture timber.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the chain saw speed regulating structure, comprise casing, and it is characterized in that: on casing, be provided with the speed governing assembly.
Further, described speed governing assembly comprises speed governing knob that is located at the casing outside and the speed adjusting module that is located in the casing, speed adjusting module is connected in the chain saw circuit for controlling motor, the end of speed governing knob is provided with ring resistance, ring resistance rotates with the speed governing knob, and the speed governing input of speed adjusting module touches with the ring resistance point and is connected.
After adopting technique scheme, the present invention has following advantage: change chain saw motor power output by changing the resistance sizes of connecting with speed adjusting module, finally show as the output speed that changes chain saw, and the resistance of series connection is regardless of gear, can realizes electrodeless variable-speed.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 is speed adjusting module and ring resistance annexation figure.
The specific embodiment
The structural representation of an embodiment of the present invention as illustrated in fig. 1 and 2, the chain saw speed regulating structure comprises casing 1, is provided with the speed governing assembly on casing.Described speed governing assembly comprises speed governing knob 2 that is located at the casing outside and the speed adjusting module 3 that is located in the casing, speed adjusting module is connected in the chain saw circuit for controlling motor, the end of speed governing knob is provided with ring resistance 21, ring resistance rotates with the speed governing knob, and the speed governing input of speed adjusting module touches with the ring resistance point and is connected.
In the foregoing description, speed adjusting module is selected the HT46R01C single-chip microcomputer for use, changes chain saw motor power output by changing the ring resistance size of connecting with speed adjusting module, finally shows as the output speed that changes chain saw, and ring resistance is regardless of gear, can realize electrodeless variable-speed.
The user has speed governing feel preferably for convenience in addition, on basis of the present invention, on the speed governing knob, bossy body is set, some bayonet sockets are set on casing, bossy body distributes and one of them bayonet fittings during with the speed governing knob, and the location, position of speed governing knob is lived.On the top end face of casing and speed governing knob, indicate respectively and bayonet socket and the corresponding scale of bossy body,, just be equivalent to be provided with the speed stage of chain saw work so that the user directly finds out the residing at that time operating rate of chain saw.
Except that above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
