Description
Technical field
The utility model relates to one advance backward gear bit switch field, particularly a kind of fork truck direction control switch on handling engineering fork truck.
Background technology
Direction control switch is generally used in the switch that handling engineering fork truck advances and falls back, usually on the Steering gear that it is arranged on below bearing circle, so that driver's operation, and existing engineering truck use amount is large, particularly fork truck and forklift, the frequency that advance falls back is very high, thus the cabinet switch that falls back of advancing use very frequent, and existing design great majority are all adopt copper sheet type contact, two sides is little steel ball centre spring supporting, plastic cement and iron sheet skid, this trouble of installing very of doing manual work, and use steel ball and spring many, during slip, resistance is larger, smooth and easy not, and it is of long duration, copper sheet elasticity is not enough, easily there is the phenomenon of bad contact, slide block due to for a long time wearing and tearing under, make surface smoothing, as long as a moving slide-bar a little, just can shift advance and the switch that falls back onto, the driving switch sometimes just changed will burn out because of bad contact, in both cases, very large mechanical wounding is caused with fork truck in capital, also cause very large potential safety hazard to user simultaneously, there is very large danger.
Utility model content
For the defect existing for prior art, the utility model provides a kind of fork truck direction control switch, this cabinet switch not only safety performance is reliable, major part all adopts metal cylinder structure to make and adopts the disposable die cast of import nylon plastic(s), by stroke slider enable contact point intact with switch contact match play wear-resisting, durable, and can't bad contact be there is, the phenomenon of slide-bar portable.
The utility model solves the technical scheme that its technical matters adopts: a kind of fork truck direction control switch, comprise control frame and driving lever, described driving lever one end is provided with swivel block, swivel block is fixed on the centre of control frame by S. A., the left and right sides, swivel block top is provided with sliding shoe, shifting block is provided with bottom swivel block, in described control frame, both sides are provided with limiting stopper, limiting stopper is arranged on the two ends, left and right of control frame, circular hole is provided with in the middle part of limiting stopper, spring and steel ball are installed in circular hole, steel ball is arranged on the opening part of circular hole, steel ball is fitted in the surface of sliding shoe, bottom described control frame, the left and right sides is provided with micro-switch, micro-switch side is provided with shell fragment, one end of shell fragment is provided with roller, roller fits on shifting block, before and after driving lever, DIP driven rotary block rotates three gears, i.e. neutral gear, D Drive and retrogressing shelves.
Further described sliding shoe to be close to circular arc order by the steel column of multiple same specification and to be formed by connecting, and forms gap between steel column and steel column.
Copper sheet blade tereminal is also provided with outside further described micro-switch.
Further described swivel block adopts the disposable die cast of import nylon plastic(s).
Further described limiting stopper one end is set as inclination, and driving lever is pushed ahead or advanced backward, and swivel block upper one end is fastened on limiting stopper oblique angle place.
Both sides, further described shifting block top are circular shapes, are provided with circular groove in the middle part of shifting block.
Actively useful effect of the present utility model is: a kind of novel forklift direction control switch, cylindrical bearing is utilized to adopt the ingenious combination of swivel block, limiting stopper and microswitch, switch open is closed more flexible, major part all adopts metal material to make, not fragile, also improve the wear resisting property of product simultaneously, durable in use, its structure is simple, reasonable in design, meets fork truck mechanical operating needs standard.
