Abstract

The utility model relates to a forklift truck direction machine which has an angle adjusting mechanism, which solves the problem that the manipulating handle is needed to be rotated with a plurality of cycles to lock the steering wheel tightly by the present angle adjustment of the forklift truck direction machine and a large locking force is required. The characteristic of the improved structure is that the utility model uses a unilateral frictional locking, namely the upper part of one side of the rotational connecting part of the direction machine frame and a fixing frame is vertically provided with a stud. One end of the stud is fixedly connected with the direction machine frame and the outer extending end of the stud is connecting with a supporting cushion block which is connected with a handle and a bolt is sleeved with a helical spring. The locking stud applies a dual linear screw thread structure and the direction machine can be locked when the handle rotates with a one-third cycle. And when the handle is loosen with about a one-third cycle the direction machine can be back on the position of deviating with the initial position with a 6 DEG. The automatic returning back of the steering wheel is realized, which make the adjusting operation and the maintenance of the driver more convenient and the comfort property of the operation of the driver is improved.

Description

Fork truck direction machine with angle-adjusting mechanism

Technical field

The utility model relates to fork truck direction machine, and specifically describing is a kind of fork truck direction machine with angle-adjusting mechanism.

Background technology

Height and bodily form fork truck direction machine according to the driver are provided with angle-adjusting mechanism.At present, the direction machine adjusting mechanism steering column and the turning rack of homemade fork truck generally adopt bilateral friction lock structure, because bilateral adjusting play is difficult to control, after chaufeur is adjusted to the proper control position with bearing circle, bar handle need be rotated a lot of circles and just bearing circle can be locked, and coupling mechanism force is very big.Equally, when adjusting the bearing circle front and back position once more, unclamping bar handle also needs very big actuating force, handles very inconvenient.

In addition, because the needs of maintenance and maintenance, the hood of fork truck need often be opened, and can interfere with hood when bearing circle is locked in extreme lower position, causes hood to open fully; And being difficult to move the steering wheel the position after unclamping bar handle 1-2 circle, bearing circle can not be realized self-return, brings difficulty for driver's inspection operation.

Along with fork truck is carried satisfying of function substantially, people are more and more higher to the requirement of human engineering, and the handling comfort of direction machine adjusting mechanism is had higher requirement.

Summary of the invention

The purpose of this utility model is: after a kind of steering wheel angle adjustment is provided, the fork truck direction machine with angle-adjusting mechanism of convenient, the reliable lock of locking operation.

Concrete structural development scheme is such.

Have the fork truck direction machine of angle-adjusting mechanism, comprise steering wheel assembly, steering column, direction machine support, instrument assembly, steering assembly and fixed support; The parallel fixed support inboard that is positioned at, direction machine support lower end is rotationally connected with the fixed support both sides;

A, above a side direction machine support and the fixed support place of being rotationally connected the vertical double-screw bolt that is provided with, double-screw bolt one end captive joint the direction machine support, the other end is overhanging, be arranged with cushion block on the double-screw bolt overhanging end, and the cradle that is being threaded, the cradle outer end is connecting handle by screw, is arranged with coil spring on the screw;

B, in both sides, steering assembly lower end and fixed support both sides the corresponding respectively pull back spring that is provided with.

Double-screw bolt is the M10 double thread, and pitch is 1.5 millimeters, and helical pitch is 3 millimeters.

The utlity model has the advantage of several respects:

1, the utility model direction machine adopts monolateral friction lock by structural development between direction machine and the mounting bracket, has overcome original direction machine and the bilateral locking of mounting bracket gap heavy handled phenomenon, has reduced the stroke of locking.

2, the tight double-screw bolt of Direction machine lock adopts the double thread structure, can Direction machine lock is tight about handle assembly rotation 1/3 circle; Increase the frictional area of cushion block and support, reduce the coupling mechanism force and the locking number of turns; Release handle 1/3 circle left and right directions machine can be got back to and depart from the preceding 6 ° of positions of initial position, realizes the bearing circle self-return, and it is more convenient to make the driver adjust Operation and maintenance, has improved the traveling comfort of driver control.

3, the utility model can realize that the clamp handle position is adjustable arbitrarily, and the phenomenon of having avoided the tight back handle of Direction machine lock position to regulate avoids handle and driver or other parts to interfere.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Fork truck direction machine with angle-adjusting mechanism comprises steering wheel assembly 1, steering column 2, direction machine support 5, spacing bearing pin 6, instrument assembly 7, steering assembly 9 and fixed support 3; Parallel fixed support 3 inboards that are positioned at, direction machine support 5 lower ends are rotationally connected with fixed support 3 both sides, see Fig. 1 and Fig. 2.

The vertical double-screw bolt 14 that is provided with above a side direction machine support 5 and fixed support 3 places of being rotationally connected, double-screw bolt 14 1 ends are fixedly welding direction machine support 5, the other end is overhanging, is set with cushion block 15 on double-screw bolt 14 overhanging ends, double-screw bolt 14 cradle 10 that is being threaded, cradle 10 outer ends are connecting handle 13 by screw 11, be set with coil spring 12 on the screw 11, see Fig. 3, double-screw bolt 14 is the M10 double thread, pitch is 1.5 millimeters, and helical pitch is 3 millimeters.

At the corresponding respectively pull back spring 8 that is equipped with in both sides, steering assembly 9 lower end and fixed support 3 both sides, see Fig. 2 and Fig. 4.

Its principle of work is to compress cushion block 15 by rotational lock handle 13, and pulling simultaneously is welded on double-screw bolt 14 on the direction machine support to left movement, and cushion block and double-screw bolt are fixed support 3 like this, and be by the friction force of mating surfaces between them that Direction machine lock is tight.The double-screw bolt of this new structure adopts purpose made double thread M10X1.5 (3/2) structure, under the situation of identical pitch, increase helical pitch, be that clamp handle revolves part 10 cradles that the turn around 3mm that moves right, thereby guarantee that the less number of turns of clamp handle assembly 4 rotations can be tight with Direction machine lock.Simultaneously, increase pull back spring 8 between fixed support and direction machine, the restoring force by extension spring forces bearing circle to be got back to foremost, is convenient to hood and opens fully.In addition, cradle 10 and handle 13 adopt spline location, accurate positioning in the clamp handle assembly.After Direction machine lock was tight, handle 13 can be pulled out any rotation left, resetted under coil spring 12 effects after being transferred to suitable position, made the tight back handle of Direction machine lock position adjustable arbitrarily.
