Description
Technical field
The utility model relates to the ergonomic arts of fork truck, is specifically related to a kind of fork truck hood lever-type locking mechanism.
Background technology
The hood (i.e. bonnet) of fork truck plays protection driving engine to whole fork truck and supports the effect of chaufeur; staff by often repeatedly folding hood realize the maintenance of fork truck power system, driving system, hydraulic efficiency pressure system etc., therefore hood effective locking and open flexibly most important.Hood catch gear common in the market, mostly be attacker's formula hood lock, there is following defect in this mechanism: 1) hood attacker drives hood lock hook to rotate by torsion spring, depart from hood link plate groove, hook rotational trajectory (circular arc) does not mate with link plate groove, and cause hook rotary course to there is dead point, must pass over dead point can depart from link plate groove completely, there is cliding friction with hook in link plate groove rectangular edge simultaneously, and resistance is large; 2) mechanism's torsion spring intensity is low, and easily comes off, and is often free rotation phenomenon; 3) mechanism's power arm: resistance arm=1:1, on market, user feedback fault rate is high, and this mechanism blockage phenomenon occurs frequent, and " do not open, do not lock " phenomenon is very common.
Utility model content
The utility model provides a kind of fork truck hood lever-type locking mechanism, and structure is simple, rapid operation, effectively, and is easy to install.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of fork truck hood lever-type locking mechanism, comprise the adapter plate be arranged on forklift frame, this adapter plate there is locking hook by pinned connection, bearing pin is arranged with main spring, described adapter plate lower end is provided with the locating convex block for this main spring torque arm of clamping, and described locking hook is provided with rotary operation mechanism.
Described rotary operation mechanism comprises the rotary handle being fixedly installed on described locking hook pivot center place, and the hand grip portion of this rotary handle is arranged with rubber coating.
The S. A. that described rotary handle is positioned at locking hook place has towards the extension of adapter plate, and this extension and described locating convex block fit tightly.
Described locking hook is provided with for installing the end junction coordinating main spring spring body with described pinned connection place, and this end junction offers for the through hole by bearing pin, the termination of bearing pin is fixed by spring cotter and plain cushion.
From above technical scheme, the utility model adopts lever principle, operate more laborsaving, catch gear high strength, locking hook can be driven to depart from hood latch by rotary handle, realize the unblock of hood, after unclamping rotary handle, locking can be made to link up with by the twisting resistance of main spring to reset, realize locking function.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present utility model is described in detail.
The utility model provides a kind of fork truck hood lever-type locking mechanism, for locking hood on forklift frame.
As illustrated in fig. 1 and 2, described fork truck hood lever-type locking mechanism comprises the adapter plate 100 be arranged on forklift frame, in the present embodiment adapter plate by the bolt of two groups of M8, plain cushion, the skid of bullet pad on forklift frame 600.Adapter plate is connected with locking hook 300 by bearing pin 200, and bearing pin is arranged with main spring 400, described adapter plate lower end is provided with the locating convex block 110 for this main spring torque arm 410 of clamping, and described locking hook is provided with rotary operation mechanism 500.
Described rotary operation mechanism 500 comprises the rotary handle 510 being fixedly installed on described locking hook pivot center place, the hand grip portion of this rotary handle is arranged with rubber coating 511, facilitates rotation process.The S. A. that described rotary handle is positioned at locking hook place has towards the extension 512 of adapter plate, and this extension and described locating convex block 110 fit tightly, and locating convex block plays position-limiting action when rotary handle action.Described locking hook is provided with for installing the end junction 310 coordinating main spring spring body with described pinned connection place, this end junction offers for the through hole 311 by bearing pin, and the termination of bearing pin is fixed by spring cotter 210 and plain cushion 220.
Described adapter plate forms fixed sturcture with bearing pin by welding, rotary operation mechanism is under artificial action power, locking can be made to link up with and to depart from hood latch, reach the object opening hood, and after slighter compress hood, and realize resetting by main spring, realize the locking function of hood, catch gear power arm: resistance arm=140:37.Because hood latch is round steel structure, and be higher pair, force of sliding friction is minimum, there is not mechanism dead point.In the present embodiment, main spring adopts the elater of diameter 1.5mm, meets function when it resets completely.
The above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
