Abstract

The utility model belongs to the control technique of engineering machinery, which mainly comprises a push-and-pull handle, a gear and rack drive mechanism and a handle locking mechanism. A gear is supported on an inner hole of a casing. A gear shaft extends from the casing and is integrated with the push-and-pull handle. A rack is supported in the casing and can move left and right by meshing with the gear. One end of a push-and-pull flexible shaft is connected with the rack, and the other end of the push-and-pull flexible shaft is connected with a machine which needs to be controlled. The handle locking mechanism can be two belleville springs which are reversely arranged on a gear shaft. The utility model has the characteristics of simple structure, small size, light weight, convenient arrangement and installation, portability and flexibility.

Description

Push-and-pull flexible axle controller

The utility model belongs to the engineering machinery control technology field, mainly proposes push-and-pull flexible axle controller, is used for turning to of engineering, road surface, compacting, transportation and mining machinery etc., and mechanisms such as commutation, speed change, lifting use the control of push-and-pull flexible axle.

At present, the operating mechanism of domestic construction machinery product also rests on the seventies level, generally be hardware type, operator can not straight line motion, all needs by push rod and passes a bridge as fulcrum, and operate with hand or hand-foot linked form, therefore the structure of controller is also different with the difference of operation piece, so its structure exists comparatively complicated, operation piece is difficult for reasonable Arrangement, the shortcoming of inconvenience during manipulation.

The purpose that the utility model proposes promptly is this, proposes a kind of push-and-pull flexible axle controller, make its have simple in structure, be easy to arrange to install, especially handle the characteristics of light and flexible.

The utility model is finished the technological scheme that the invention task takes: it mainly includes drawing handle, rack and pinion drive mechanism and handle locking mechanism; Gear support is on the endoporus of housing, thereby gear shaft stretches out housing to be connected with handle set and drawing handle composition one, tooth bar is bearing in the housing can make move left and right with gear engagement, and push-and-pull flexible axle one end connects with tooth bar, and the other end is connected required control mechanically.

Handle locking mechanism can be two belleville springs and is installed in dorsad on the gear shaft, between housing and handle set.

Push-and-pull flexible axle controller is fixedly mounted on the machinery instrument plate.

The utility model simplicity of design is reasonable, is easy to make and uses, and it is little, in light weight to have a volume, and the characteristics of operation light and flexible are highly suitable for turning to of machineries such as engineering, transportation, commutate the control of speed change, elevator mechanism.

The accompanying drawing that the utility model embodiment provides is;

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model drive mechanism schematic representation.

Accompanying drawing 3 is the utility model locking mechanism schematic representation.

Accompanying drawing 4 is gear, tooth bar mesh schematic representation.

The embodiment who provides is in conjunction with the accompanying drawings further specified the utility model;

Structure as shown in drawings: the utility model mainly includes drawing handle 1, gear, tooth

bar drive mechanism

3,4 and handle locking mechanism 9, its middle gear 3 is bearing on the endoporus of the involutory housing in the left and right sides 2 can make axial rotation, the splined shaft 12 that the handle set 11 and the gear 3 of drawing handle 1 stretches out housing is connected into one, tooth bar 4 is bearing in the housing and meshes with gear 3, it can stretch out housing and seesawing by the hole that housing sets, and the pull bar 10 of flexible axle one end is connected with the axis hole 5 of tooth bar 4; Handle locking mechanism 9 can adopt two belleville springs, it is installed on the gear spline axle dorsad, between housing and handle set, drawing handle is played locking effect voluntarily, in order to prevent the wearing and tearing of housing exterior edge face and handle set interior edge face, a pad 8 that certain degree of hardness is arranged respectively is housed, and handle set 11 connects with gear spline axle 12 and pieces together tightly with set screw nut 6 and gear attachment screw, and handle locking mechanism is worked.

The pull bar 10 of push-and-pull flexible axle one end is connected with the axis hole 5 of tooth bar, and the other end is connected required control mechanically.

Entire controller is fixedly mounted on the instrument panel of machinery by the screw of housing.
