Abstract

The utility model discloses an anti-misoperation mechanical control device arranged between a base and a handle, a reset spring is installed on the handle, a guide block is fixed at the lower end of the handle, an upper pin and a lower pin are formed on the guide block, an upper guide slot and a lower guide slot are formed in the base, the upper guide slot and the lower guide slot take the shapes of a strip, a communicated inverted V-shaped slot is further formed in the top part of the upper guide slot, and the upper pin and the lower pin are respectively positioned in the inverted V-shaped slot, the upper guide slot and the lower guide slot in an upper-and-down moving manner. When the anti-misoperation mechanical control device is operated normally, the reset spring is compressed firstly, then the handle is pulled to drive the base to rotate around the center, so as to output the mechanical motion to other mechanisms; when accidental acting force is acted on an operation rod, only the guide block rotates around the lower pin, but the base does not rotate, so that the mistaken mechanical motion is not produced.

Description

A kind of anti-misoperation machinery controls

Technical field

The utility model relates to the technical field of fork truck, special relevant with the anti-misoperation machinery controls of fork truck control handle.

Background technology

Fork truck is industrial transportation vehicle, refer to member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short range hauling operation.Be widely used in harbour, station, airport, goods yard, factory floor, warehouse, Transfer center and DISTRIBUTION CENTRE etc., and can enter the handling, the transport operation that in cabin, compartment and freight container, carry out pallet cargo, be requisite equipment in pallet traffic, Container Transport.

The control handle 10 of tradition fork truck as depicted in figs. 1 and 2; to be fixed on pedestal 30 by simple pin 20; by certain direction driving handle 10; handle 10 drives pedestal 30 deflections to control the fork truck control part being connected with pedestal 30; control fork truck action, control handle does not have the anti-error defencive function of mistake proofing.In the time surprisingly encountering handle 10, while doing other things as driver, hand is encountered or driver causes maloperation etc. because of fatigue because of carelessness, fork truck there will be maloperation (accidental operation), this operation may cause serious consequence, such as in armful folder handling process, to embracing the accidental operation of folder control handle, may cause embracing folder accessory and surprisingly unclamp, goods drops and leads to a disaster.

Therefore, inventor's customized design goes out a kind of anti-misoperation machinery controls, applies to the control handle of fork truck, uses the problem that solves the maloperation of fork truck control handle, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of anti-misoperation machinery controls, to prevent handle maloperation, improves the safety performance of fork truck.

In order to reach above-mentioned purpose, solution of the present utility model is:

Anti-misoperation machinery controls, be arranged between pedestal and handle, retracing spring is installed on handle, at handle, at its lower end fixed guide piece, on orienting lug, form pin and lower pin, form upper rail and lower guide channel on pedestal, upper rail and lower guide channel are strip, the reverse V-shaped groove of connection is also formed on the top of upper rail, and upper pin and lower pin are placed in reverse V-shaped groove, upper rail and lower guide channel in the mode of can slide up and down respectively.

On described handle, form upper baffle ring, pedestal is provided with lower baffle ring, and retracing spring is enclosed within on handle, and the top and bottom of retracing spring are against respectively on upper baffle ring and lower baffle ring.

Adopt after said structure, when the utility model normal running, need first compression reseting spring, make the upper pin on orienting lug move to upper rail bottom from the reverse V-shaped groove of pedestal, lower pin also moves to bottom from the lower guide channel top of pedestal, then pull handle, drive pedestal around center rotating, thereby realize other mechanism's output mechanical movements; In the time that accidental action masterpiece is used in joystick, the upper pin that only has orienting lug moves in the reverse V-shaped groove of pedestal, and orienting lug rotates around lower pin, and not rotation of pedestal can not produce wrong mechanical movement like this.

Label declaration

Handle 10, pin 20, pedestal 30;

Handle 1, upper baffle ring 11, retracing spring 2, pedestal 3, upper rail 31, lower guide channel 32, reverse V-shaped groove 33, lower baffle ring 34, orienting lug 4, upper pin 41, lower pin 42.

The specific embodiment

As shown in Figures 3 to 5, the anti-misoperation machinery controls that the utility model discloses, is arranged between pedestal 3 and handle 1.

Retracing spring 2 is installed on handle 1, and this embodiment specifically forms upper baffle ring 11 on handle 1, and pedestal 3 is provided with lower baffle ring 34, and retracing spring 2 is enclosed within on handle 1, and the top and bottom of retracing spring 2 are against respectively on upper baffle ring 11 and lower baffle ring 34.At handle 1 lower end fixed guide piece 4.

On orienting lug 4, form pin 41 and lower pin 42.

On pedestal 3, form upper rail 31 and lower guide channel 32, upper rail 31 and lower guide channel 32 are strip, and the reverse V-shaped groove 33 of connection is also formed on the top of upper rail 31.

Upper pin 41 and lower pin 42 are placed in reverse V-shaped groove 33, upper rail 31 and lower guide channel 32 in the mode of can slide up and down respectively.

When the utility model normal running, as shown in Figure 6, need first compression reseting spring 4, make the upper pin 41 on orienting lug 4 move to upper rail 31 bottoms from the reverse V-shaped groove 33 of pedestal 3, lower pin 42 also moves to bottom from lower guide channel 32 tops of pedestal 3, then as shown in Figure 7, pull handle 1, drive pedestal 3 around center rotating, thereby realize other mechanism's output mechanical movements.

In the time that accidental action masterpiece is used in joystick, as shown in Figure 8, only have upper pin 41 sway in the reverse V-shaped groove 33 of pedestal 3 of orienting lug 4, orienting lug 4 rotates around lower pin 42, and not rotation of pedestal 3 can not produce wrong mechanical movement like this.

The utility model arranges a generation that needs the mechanism of secondary operation to avoid accidental operation, and operating personal needs could operate fork truck by before push away again or retreat etc. downwards.Like this, the utility model can prevent because accidental operation brings risk, and the not little handle 1 that collides of chaufeur can not cause fork truck maloperation, the safety performance that improves fork truck, this mechanism structure is simple, operates simple and easy, truck driver need not can be learned through training, and manufacturing cost is also very low.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
