Background technique
Shift fork in machinery is mainly used for stirring shifting slide gear, changes its position on gear shaft, can move up and down or move left and right, thus realize different speed.Or the control of clutch in engineering goods, such as end face is in conjunction with the structure of tooth, and the structure of interior external tooth, all needs to realize combining and being separated by its part of fork controls.Also having a kind of be the control of electrical equipment in engineering goods is also need shift fork to realize the closed of switch and to disconnect, and is generally that in electrical appliance kit, card power switch is touched on each one of both sides, stirs, thus realize the running of lathe different direction about shift fork or up and down.But some control structures firm being difficult to stirs; or shift fork weares and teares comparatively serious in Long-Time Service process; not very laborsaving when making sometimes to stir; lack corresponding protection when being subject to larger stress and break; and traditional shift fork does not possess the device of buffering stress to protect shift fork body, shift fork is reduced working life.
Model utility content
The technical problem that the utility model mainly solves is to provide the shift fork that a kind of band is inserted in balance ball draught spring, both the stretching cushioning ability of shift fork body can be improved, again by stretching damping balance spring device is gone here and there cover steel column play balance shift fork effect, this physical efficiency of shift fork is worked more stably.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of band to be inserted in the shift fork of balance ball draught spring, comprise shift fork handle set, shift fork arm and stretching damping balance spring device, described shift fork handle set central authorities offer mounting hole, described shift fork arm is located at described shift fork handle set two ends, install bottom described shift fork arm and be provided with shift fork fork pin, described stretching damping balance spring device two ends are connected and fixed on described shift fork arm, described stretching damping balance spring body comprises extension spring body and beading bar, described extension spring body is installed and is located at described beading bar two ends, on described beading bar, cover has multiple ball body.
In the utility model preferred embodiment, described extension spring body one end is fixed on described shift fork arm arm face by screw, the described extension spring body the other end is connected and fixed described beading bar, and described beading bar two ends all symmetrical installation are provided with described extension spring body.
In the utility model preferred embodiment, described stretching damping balance spring device lateral level is installed and is arranged between described shift fork arm.
In the utility model preferred embodiment, described ball body connecting length is less than described beading pole length.
In the utility model preferred embodiment, described ball body is single solid steel cylinder.
In the utility model preferred embodiment, described shift fork handle set and described shift fork arm, described shift fork are pitched pin and are integral type and cast linkage structure.
The beneficial effects of the utility model are: the utility model both can improve the stretching cushioning ability of shift fork body, the situation that in avoiding shift fork body to use, stress excessively bursts apart, extend shift fork body working life, again by stretching damping balance spring device is gone here and there cover steel column play balance shift fork effect, this physical efficiency of shift fork is worked more stably.
