Description
Technical field
The utility model relates to mower, and more particularly, it relates to a kind of mower handrail fold mechanism.
Background technology
Mower (Lawnmower) is also known as weeder, grass mower, lawn mower etc.Mower be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it is made up of cutterhead, engine, road wheel, running gear, blade, handrail, control section.Cutterhead is contained on road wheel, and cutterhead is equipped with engine, and the output shaft of engine is equipped with blade, and blade utilizes the High Rotation Speed of engine to improve in speed a lot, saves the activity duration of weeding workman, decreases a large amount of human resources.
Mower generally comprises handrail and lower handrail, generally for and be convenient to collection, then can be set to hinged between upper handrail and lower handrail, handrail can be drawn on lower handrail, thus be convenient to collection, but lower handrail still can endwaysly stand on mower, still can bring inconvenience to collection, in order to also lower handrail also be drawn in, need its lower handrail to disassemble, making more to bother, so current used mower handrail fold mechanism has certain room for improvement.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of mower handrail fold mechanism, effective two supports are fixed and locked of energy, and play can not occur.
For achieving the above object, the utility model provides following technical scheme: a kind of mower handrail fold mechanism, comprise the lower handrail being provided with upper bracket and the mower body being provided with lower carriage, described upper bracket and lower carriage are mutually hinged by jointed shaft, described upper bracket is fixedly connected with locking plate near lower carriage side, described lower carriage is fixedly connected with the lower locking plate corresponding with upper locking plate near upper bracket side, described upper locking plate and lower locking plate are equipped with intermeshing latch, described upper bracket is also provided with the actuator for driving the latch on the latch on upper locking plate and lower locking plate to engage each other locking.
Adopt such scheme, upper locking plate and lower locking plate generation move toward one another is driven by actuator, to realize the latch on locking plate and the latch on lower locking plate engages each other, thus upper bracket and lower carriage can be completely fixed and lock, avoid the situation that play occurs, improve the experience of client.
As preferably, described upper locking plate and lower locking plate are all sheathed on jointed shaft.
Adopt such scheme, upper locking plate, lower locking plate and the equal concentric of jointed shaft are arranged, make structure more compact, avoid locking plate, lower locking plate is separately positioned on different positions from jointed shaft and causes needing to occupy larger region, make entirety unsightly.
As preferably, be also provided with elastic component between described upper locking plate and lower locking plate, and elastic component is sheathed on jointed shaft.
Adopt such scheme, because upper locking plate and lower locking plate are when locking state, elastic component is in compressive state, so elastic component has certain elastic potential energy, when needs unclamp upper locking plate and lower locking plate draws upper bracket and lower carriage in carry out rotation, by the elastic force of elastic component, upper locking plate is directly separated with lower locking plate, cannot be separated in mode manually, make operation more convenient.
As preferably, described actuator comprises rotary handle, steady pin and collision piece;

Described collision piece to be fixed on jointed shaft and to conflict away from the side of lower locking plate with lower carriage and is connected;
Described rotary handle rotates to drive jointed shaft to drive lower locking plate and upper locking plate move toward one another.
Adopt such scheme, by rotating rotating handles, the jointed shaft be fixed on rotating handles can move along its axial direction, and collision piece and jointed shaft are conflicted with lower carriage while fixing, thus collision piece drives lower carriage also to move along the axial direction of jointed shaft, and then the lower locking plate locking plate direction motion be upward positioned on lower carriage, until upper locking plate and lower locking plate conflict to make the latch of its inside engage mutually, and rotary handle is after over-rotation, its external force be subject to is only the power of jointed shaft axial direction, therefore when there is no external force, rotary handle can not rotate automatically, and then rotary handle is also fixed, thus realize the stuck function of locking.
As preferably, the latch on the latch of described upper locking plate and lower locking plate is all arranged in circumference.
Adopt such scheme, the dynamics that the locking that can improve upper locking plate and lower locking plate is set of multiple latch, avoid occurring the situations such as skidding and causing situation about cannot lock to occur.
As preferably, also comprising handrail, between described upper handrail and lower handrail, being provided with the gathering mechanism for upper handrail and lower handrail being folded.
Adopt such scheme, folding for twice of mower handrail can be realized by gathering mechanism and fold mechanism, make the volume of mower less, be convenient to collection.
The utility model is in terms of existing technologies:
1, engaged each other the function realizing being locked by the latch on the latch on upper locking plate and lower locking plate, avoid the situation of upper bracket and lower carriage generation play to occur;
2. the convenient degree that effectively can improve operation is set by elastic component, does not need locking plate and lower locking plate in manual separation.
