Description
Technical field
The present invention relates to a kind of device locking tractor hood, specifically a kind of hood lock of tractor.
Background technology
Existing a kind of hood lock of tractor is mainly made up of snap close, lock catch pull rod, fixed plate soldering member, lower locking board and twist lock.Snap close is arranged on hood, and fixed plate soldering member is arranged on the body of tractor, and lower locking board and fixed plate soldering member are hinge-coupled, and twist lock is installed in the holes that lower locking board is provided with, and lock catch pull rod is installed in the hole being provided with in the middle part of twist lock.During use, first lock catch pull rod is buckled on snap close, then lower locking board is pulled down and make it be attached on the surface of fixed plate soldering member.Tractor in the course of the work, due to the impact that hood lock is vibrated, often results in lower locking board and leaves the surface of fixed plate soldering member, thus cause lock catch pull rod to be separated with snap close, make hood can not be locked on body.The impact that the most existing hood lock is the most vibrated, makes hood not reliably to be locked on body.Simultaneously because the structure of above-mentioned hood lock is complex, therefore 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 can not only make hood reliably be locked on body, and not vibrated by tractor is affected, and simple in construction, low cost of manufacture.
nullIn order to solve above-mentioned technical problem，One hood lock of tractor of the present invention，Containing lock support、Locking plate、Spring base and torque spring，Lock support includes base、Fixed plate、Left limit plate and right limit plate，Left limit plate and right limit plate are separately positioned on a left side for fixed plate、On right dual-side，The bottom of fixed plate is provided with through hole，This through hole be arranged over groove，The left upper portion of fixed plate is provided with skewed slot，Fixed plate is arranged on base，The bottom of locking plate is provided with through hole，This through hole be arranged over long recess，It is arranged over clasp on the left of this long recess，The left side of locking plate is provided with left limit arm，This left limit arm is provided with drag hook hole，The mounting hole of torque spring one support arm it is provided with on the left of locking plate，The right side of locking plate is provided with right limit arm，Spring base is multi-step rod structure，This multi-step rod structure comprises the step post for installing torque spring，The central authorities of this multi-step rod structure are provided with through hole，The through hole that the through hole that locking plate bottom is provided with is provided with lock support fixed plate bottom 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 on the left of locking plate，Another support arm of torque spring is positioned on lock support base，Spring base is arranged in lock support fixed plate，Locking plate can swing around spring base.
Described spring base is arranged in lock support fixed plate by bolt and nut.
The through hole that described lock support fixed plate bottom is provided with is provided with copper sheathing.
When 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, locking plate is pulled by drag hook, locking plate is made to swing around spring base, until the right side of locking plate long recess is corresponding with lock support fixed plate groove, at this moment the connecting rod on hood is pressed in right side and the lock support fixed plate groove of locking plate long recess, finally unclamp drag hook, locking plate swings back in situ under the effect of torque spring, hood connecting rod is closely together by the clasp being at this moment arranged on the left of locking plate long recess, so that hood is reliably locked on body, do not vibrated by tractor and affected；Simultaneously because above-mentioned hood lock is only made up of lock support, locking plate, spring base and torque spring etc., therefore simple in construction, low cost of manufacture.
