Description
Technical field
This utility model relates to retaining mechanism technical field, particularly relates to a kind of back door of garbage truck retaining mechanism.
Background technology
Back door retaining mechanism is comparatively important parts in compartment removable garbage truck, and its major function is to keep back door to close in vehicle transport way, after vehicle transport to garbage disposal plant, is opened at the back door of garbage bin, makes rubbish unload; Traditional back door locking mechanism reliability is poor, it is easily caused back door deformation so that when back door closing motion will complete, back door moves down and causes in the hook portion that the lock pin on back door should drop on latch hook, result but drops on the outside of latch hook, therefore causes the phenomenon occurring to lock back door.
Chinese invention patent discloses the connecting rod type rear door locking mechanism for garbage truck that the patent No. is CN102133984A, it is applied on envelope that garbage truck carriage is hinged and back door, including oil cylinder, moving block, connecting rod and latch hook, described moving block and latch hook are arranged on the sidewall in compartment respectively through bearing pin, one end of described moving block is hinged with described oil cylinder, the piston rod end of oil cylinder is hinged on described back door, the other end of described moving block is hinged with one end of described connecting rod, the other end of connecting rod is hinged with latch hook, the end of described latch hook has the draw-in groove of and lock pin clamping, described lock pin is fixed on back door, the envelope that moving block rotates institute overlay area fixes a spacer pin. although, technique scheme can be greatly improved the success rate of closing back door and the reliability of retaining mechanism, the draw-in groove of latch hook end is arranged upward, on the one hand can with lock pin clamping, on the other hand can support back door weight to a certain extent so that back door is unlikely to deform, but its only one of which latch hook and lock pin, latch hook is in supporting back door process, and latch hook end and draw-in groove are easy to deform, thus affecting the reliability of its clamping with lock pin and locking, simultaneously, spacer pin is arranged on moving block and rotates on the envelope of institute overlay area by it, in the opening process of back door, the control and regulation of latch hook rotational angle are indirectly by it, once latch hook does not separate with lock pin completely, oil cylinder drives elongation always, not only can not open back door, be also easy to cause oil cylinder to damage.
Summary of the invention
The purpose of this utility model is in that for the deficiencies in the prior art, it is provided that a kind of reasonable in design, and simple in construction has two latch hooks and lock pin, and closing back door success rate is high, the back door of garbage truck retaining mechanism of retaining mechanism good reliability.
For achieving the above object, this utility model is by the following technical solutions:
A kind of back door of garbage truck retaining mechanism, it is applied on envelope that garbage truck carriage is hinged and back door, this retaining mechanism includes a driver, two latch hooks and two lock pins, the equal interval of said two lock pin is arranged on bottom, back door, the middle part of said two latch hook is all hinged on envelope sidewall, and the clamping corresponding to two lock pins respectively of the hook portion that is provided with of two latch hook one end, the said two latch hook other end is hinged by the regulating part of an adjustable-length, one of them latch hook other end is provided with adjutage, described adjutage is for hinged with driver one end, the driver other end is hinged on top, back door, rotate on the envelope opening institute overlay area at least provided with a limited block at two latch hooks.
Described regulating part is connected and composed by two threaded rods and an adjusting nut, and described two threaded rod one end are hinged with two latch hook other ends respectively, and two threaded rod other ends threaded to regulate regulating part length with adjusting nut two ends respectively.
Described two threaded rod other ends are threaded respectively a location nut, and two positioning screw mothers lay respectively at adjusting nut two ends. This design can after adjusting regulating part length, by by two position nuts be tightened on adjusting nut two ends, with play prevent adjusting nut loosen and cause displacement.
One of them latch hook one end of corresponding two latch hooks of described limited block tilts to be fixed on envelope.
Described driver is cylinder or hydraulic jack.
Described envelope and top, back door are ramp structure.
Being connected by a upset free bearing being positioned at car top between described envelope and back door, the fraising of described upset free bearing is circular hole.
This utility model adopts above technical scheme, during installation, keep back door closure state, control the distance between two latch hook other ends by regulating regulating part length, so that it is guaranteed that under driver contraction state, the hook portion of two latch hooks can distinguish corresponding lock pin clamping; In open back door process, driver first extends a bit of, drive the adjutage that one of them latch hook other end is provided with descending, and respectively two latch hook other ends applying active forces are made two equal swung downward of the latch hook other end by regulating part, owing to being all hinged on envelope sidewall in the middle part of two latch hooks, thus two latch hooks rotate rotating around hinged place in the middle part of it, the hook portion of two latch hook one end is driven to be swung up respectively, so that the lock pin disengagement that the hook portion of two latch hooks is corresponding respectively; Along with the continuation of driver extends, two latch hook one end continue up swing contact and are resisted against on limited block, under the position-limiting action of limited block, two latch hook one end stop swinging, driver continues elongation and opens knocking on back door to turn, thus completing first to open latch hook to open the opening process at back door again.
This utility model adopts two latch hooks and two lock pins, strengthens the lock ability at back door, improves the success rate of closing back door, has also disperseed locking stress point simultaneously so that back door is more difficult generation local deformation in life-time service; The locking mode of clamping lock pin from top to bottom taked by two latch hooks so that latch hook is without bearing the gravity at back door, thus avoiding latch hook to deform; Regulating part is adopted to connect two latch hook other ends, it is possible not only to make two latch hooks realize linkage, but also the distance between two latch hook other ends can be regulated by the length of adjustment regulating part, so that it is guaranteed that the clamping reliable, accurate between two latch hook one end and two lock pins, reduce in the middle part of two latch hooks and the cooperation installation difficulty of two lock pins; One of them latch hook one end corresponding for limited block is inclined at this latch hook and rotates on the envelope opening institute overlay area, can more straightforward, be accurately controlled the pendulum angle of latch hook one end, and make its each pendulum angle can be consistent, simultaneously by limited block to change the force direction of driver, to open back door. This utility model is reasonable in design, simple in construction, has two latch hooks and lock pin, and closing back door success rate is high, retaining mechanism good reliability.
