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, with specific rotation speeds, carry out work, timber for differing texture, degree of wear difference to the chain of chain saw, such as cutting on the timber harder in speciality, may need chain saw to be cut with lower speed, prevent the chain fracture that crumbles even.
Summary of the invention
Problem to be solved by this invention just is to provide a kind of chain saw speed regulating structure, 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: chain saw speed regulating structure, comprise casing, and it is characterized in that: be provided with the speed governing assembly on casing.
Further, described speed governing assembly comprises the speed governing knob that is located at the casing outside and is located at the speed adjusting module in 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 and is connected with ring resistance point.
After adopting technique scheme, the present invention has following advantage: by changing the resistance sizes of connecting with speed adjusting module, change the chain saw output power of motor, finally show as the output speed that changes chain saw, and the resistance of series connection can be realized electrodeless variable-speed regardless of gear.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
The structural representation that Fig. 1 is 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, chain saw speed regulating structure, comprise casing 1, is provided with the speed governing assembly on casing.Described speed governing assembly comprises the speed governing knob 2 that is located at the casing outside and is located at the speed adjusting module 3 in 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 and is connected with ring resistance point.
In above-described embodiment, speed adjusting module is selected the HT46R01C single-chip microcomputer, by changing the ring resistance size of connecting with speed adjusting module, changes the chain saw output power of motor, finally shows as the output speed that changes chain saw, and ring resistance, regardless of gear, can be realized electrodeless variable-speed.
In addition in order to facilitate the user that speed governing feel is preferably arranged, 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 location, the position of speed governing knob is lived.Indicate respectively the scale corresponding with bayonet socket and bossy body on the top end face of casing and speed governing knob, so that the user directly finds out chain saw residing operating rate at that time, just be equivalent to be provided with the speed stage of chain saw work.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
