Description
Technical field
The present invention relates to semitrailer technical field, particularly to for locking telescopic load bed telescopic location
Device.
Background technology
Semitrailer has been obtained for using widely, but owing to type of merchandize is various, the load bed of semitrailer
Needing possess extensibility, when load bed contains longer component, load bed needs extension to amplify,
To hold component.Load bed can be divided into load bed pedestal and extensible frame at present, and extensible frame is set with slidably
In load bed pedestal, and extensible frame is provided with multiple stopper slot, and each stopper slot all represents a gear,
To insert the position of locking member locking extensible frame.Traditional locking member design is relatively simple, at present
Using is exactly latch the most frequently, and during use, latch passes load bed pedestal and allocates the stopper slot of extensible frame into
In, complete the position locking of extensible frame, owing to latch needs repeatedly to plug, operation bothers very much.
Summary of the invention
It is an object of the invention to provide telescopic load bed telescopic location locking device, arrange ingenious, operation letter
Just.
The object of the present invention is achieved like this: telescopic load bed telescopic location locking device, including installing
Frame, latch body, handle, the fixing cylinder, back-moving spring, backup plate, fixing being installed on load bed pedestal
Strutbeam on load bed pedestal, described installing rack is integrally fixed with strutbeam, and described backup plate is removably pacified
It is contained on installing rack；
Described latch body one end is sleeved in cylinder lumen and movably movably through load bed base
Frame, the described latch body other end is movably through backup plate and installing rack；On described latch body rotationally
Being provided with the compress set coaxial with latch body, one side relative with compressing set on described backup plate is provided with and is available for inserting
The sleeve that shank activity passes, described back-moving spring one end is sleeved on sleeve, described back-moving spring another
End is sleeved on to compress and puts；
It is coated with fixing axle on described latch body, described fixing axle exposes one section of latch body rotationally
Being provided with rolling element, described cylinder is provided with that contact all the time with rolling element, spiral distribution, permissible
Guide the contact trace face that rolling element rolls, the spiral center in described contact trace face to load bed pedestal direction
Coaxial with latch body, described cylinder is additionally provided with the spacing head for limiting rolling element final position, described
Spacing head is in the one end on contact trace face closest to load bed pedestal；
The handle being easy to control latch body spinning movement also it is coated with on described latch body；
When extensible frame is in flexible extended mode, pulls handle and make latch body screw out the spacing of extensible frame
Groove, described in compress set compression reseting spring；
When extensible frame stopper slot just to latch body, need lock extensible frame position time, release handle makes
Back-moving spring release elastic potential energy, described latch body can be inserted in stopper slot just, and described rolling element is lucky
Against spacing head, described handle is against on strutbeam just.
When the length dimension of whole load bed needs to be expanded, first hold handle, utilize handle to make to insert
Shank rotates and is completely disengaged from stopper slot, meanwhile, compresses set compression reseting spring so that back-moving spring
Because deformation accumulates elastic potential energy；Then extensible frame slides in load bed pedestal, to increase the chi of whole load bed
Very little；Operator needs to hold handle always, when the length dimension of load bed reaches requirement, and fine-tuning extension
The position of frame makes the stopper slot of extensible frame just to latch body, and release handle this moment, back-moving spring discharges bullet
Property potential energy, compress set by being compressed power from back-moving spring, compress set with latch body insertion stopper slot
In.
During latch body inserts stopper slot, rolling element is along contact trace towards load bed pedestal direction
Spin motion, until rolling element leans against on spacing head, the screw-in action of latch body can be terminated, thus
Ensure that latch body screws in the stationarity of motion, play good guide effect.
Compared with prior art, the beneficial effects of the present invention is: be first arrange ingenious, easy and simple to handle,
Utilize back-moving spring dexterously, as long as breaking by handle, it is possible to make latch body screw out stopper slot, it is simple to
Extensible frame slides in load bed pedestal, and release handle can be ordered about latch body and be screwed in stopper slot, it is simple to locking
Extensible frame position in load bed pedestal；It two is that cylinder is provided with spiral helicine contact trace face, permissible
The screw-in track of guide body exactly, it is ensured that screw in the stability of motion.
As a further improvement on the present invention, described strutbeam is provided with catch means, when handle leans against just
Time on strutbeam, described handle device of the lock bit pins.It is to prevent handle in the process of moving because jolting
Cause off normal phenomenon, finally prevent latch body from producing off normal phenomenon.
As a further improvement on the present invention, described catch means includes a pair riser, pressing plate, locking machine
Structure, described riser is vertically fixed on strutbeam, and when handle is against on strutbeam, described handle is in a pair
Between riser and be in below pressing plate, described pressing plate one end is hinged on one of them riser upper end, described pressure
The plate other end and can be locked by locking mechanism in another riser upper end with inserting when lock-bit.Arrange simple,
Easily fabricated.
As a further improvement on the present invention, described handle is in and compresses between set and fixing axle, and institute
State handle center's axle perpendicular with latch body central shaft.It is for the ease of installing.
