Technical field
The present invention relates to a kind of device of locking tractor hood, specifically a kind of hood lock of tractor.
Background technology
Existing a kind of hood lock of tractor mainly consists of snap close, lock catch pull rod, fixed head soldering member, lower latch plate and twist lock.Snap close is arranged on hood, and fixed head soldering member is arranged on the body of tractor, and lower latch plate and fixed head soldering member are hinge-coupled, and twist lock is installed in two holes that lower latch plate is provided with, and lock catch pull rod is installed in the hole that twist lock middle part is provided with.During use, first lock catch pull rod is buckled on snap close, then lower latch plate is pulled down and made on its surface that is attached to fixed head soldering member.Tractor in the course of the work, due to the vibrated impact of hood lock, often causes lower latch plate to leave the surface of fixed head soldering member, thereby causes lock catch pull rod and snap close to be separated, and hood can not be locked on body.Therefore easily vibrated impact of existing hood lock, can not be locked on body hood reliably.While is because the structure of above-mentioned hood lock is comparatively complicated, so manufacturing cost is high.
summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hood lock of tractor, and this lock not only can make hood be locked at reliably on body, is not subject to the impact of tractor vibration, and simple in structure, low cost of manufacture.
In order to solve the problems of the technologies described above, a kind of hood lock of tractor of the present invention, contain lock support, locking plate, spring base and torque spring, lock support comprises base, fixed head, left limit plate and right limit plate, left limit plate and right limit plate are separately positioned on a left side for fixed head, on right dual-side, the bottom of fixed head is provided with through hole, the top of this through hole is provided with groove, the left upper portion of fixed head is provided with skewed slot, fixed head is arranged on base, the bottom of locking plate is provided with through hole, the top of this through hole is provided with long recess, this top, long recess left side is provided with clasp, the left side of locking plate is provided with left limit arm, this left limit arm is provided with drag hook hole, locking plate left side is provided with the mounting hole of torque spring one support arm, the right side of locking plate is provided with right limit arm, spring base is many steps rod structure, in this many steps rod structure, comprise for installing the step post of torque spring, the central authorities of this many steps rod structure are provided with through hole, the through hole that the through hole that locking plate bottom is provided with and lock support fixed head bottom are provided with is sleeved on spring base, torque spring is sleeved on torque spring seat, in the torque spring mounting hole that one support arm spiral-lock of torque spring is provided with in locking plate left side, another support arm of torque spring is positioned on lock support base, spring base is arranged on lock support fixed head, locking plate can swing around spring base.
Described spring base is arranged on lock support fixed head by bolt and nut.
In the through hole that described lock support fixed head bottom is provided with, be provided with copper sheathing.
While using above-mentioned hood lock, the base of lock support can be arranged on body, the inwall of hood lower end is provided with connecting rod, when closing hood, by drag hook, pull locking plate, locking plate is swung around spring base, until the right side of locking plate long recess is corresponding with lock support fixed head groove, at this moment the connecting rod on hood is pressed in the right side and lock support fixed head groove of locking plate long recess, finally unclamp drag hook, locking plate swings back original position under the effect of torque spring, at this moment the clasp that top, locking plate long recess left side is provided with is closely together hood connecting rod, thereby make hood be locked at reliably on body, be not subject to the impact of tractor vibration, simultaneously because above-mentioned hood lock only consists of lock support, locking plate, spring base and torque spring etc., therefore simple in structure, low cost of manufacture.
