Description
Technical field
A rear door locking device for small-sized airtight waste-skip, belongs to waste-skip latching device technical field.
Background technology
Along with socioeconomic develop rapidly, people are more and more higher to sanitary requirement, and small-sized airtight waste-skip, due to its maneuverability, good leak tightness, effectively prevent the secondary pollution in garbage collecting and transferring process, obtains wideling popularize of city management department.
The rear door locking device of current domestic small-sized airtight waste-skip mainly contains two kinds of forms: one is oil cylinder auto lock, and this just requires that waste-skip is equipped with the hydraulic power units such as oil sources, bring vehicle install complicated, costly, the problem such as car load is heavy; Another kind is that snap lock is manually locked, but this mode automation is low, and operating environment is poor, can not meet the requirement of environment-friendly high-efficiency.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of simple and light, automation mechanized operation degree is high, the back door of garbage truck latching device of reliable lock.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of rear door locking device of small-sized airtight waste-skip, casing is hinged with at the large beam rear part of waste-skip, back door and casing upper articulation, comprise latch hook, latch hook bearing, electric pushrod and handspike bearing, described latch hook bearing and handspike bearing are installed in bottom half, described electric pushrod installation end and handspike bearing hinged, one end of drive end and latch hook is hinged, middle part and the latch hook bearing of described latch hook are hinged, back door is compressed after the other end rotation of latch hook, along the intrinsic sealing joint strip of back door circumference glue.
The power supply on the power acquisition waste-skip chassis of described electric pushrod.
Described latch hook is " 7 " font, and the one end compressing back door after rotating is semicircular structure.
Described sealing joint strip is round outside but spuare inside through-hole structure.
Described latch hook becomes " 7 " font structure by jam plate, backing plate, an otic placode assembly welding.
Compared to the prior art the utility model has following beneficial effect.
One, this apparatus structure is simply light, only adopt several simple, locking work that low cost parts just complete back door, also degree that is convenient, automation mechanized operation of simultaneously installing is also high, only need the drive end of electric pushrod to promote latch hook during work to rotate, until the compression back door, one end of latch hook, back door press seal adhesive tape, just achieve locking work, and locking effect is reliable.
Two, this device adopts electric pushrod as dynamical element, adopts waste-skip chassis own power source as the power supply of electric pushrod, not only easy for installation, oad is little, and implementation cost is low, and degree of automation is high.
Three, the latch hook of this device adopts " 7 " font, and the one end compressing back door after rotating is semicircular structure, and such designing and producing is simple, is also conducive to latch hook to the incision at back door and compression simultaneously.
Four, the sealing joint strip of this device is designed to round outside but spuare inside logical empty formula cross section, and adhesive tape compression ratio is large, and when back door compresses, sealing is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic cross-section of the utility model sealing joint strip;
Fig. 3 is the structural representation of the utility model latch hook;
In figure, 1 is back door, and 2 is sealing joint strip, and 3 is latch hook, and 4 is latch hook bearing, and 5 is electric pushrod, and 6 is waste-skip chassis, and 7 is handspike bearing, and 8 is casing, and 9 is jam plate, and 10 is backing plate, and 11 is an otic placode.
Detailed description of the invention
As shown in Figure 1-Figure 3, a kind of rear door locking device of small-sized airtight waste-skip, casing 8 is hinged with at the large beam rear part of waste-skip, back door 1 and casing 8 upper articulation, comprise latch hook 3, latch hook bearing 4, electric pushrod 5 and handspike bearing 7, described latch hook bearing 4 and handspike bearing 7 are installed in bottom casing 8, described electric pushrod 5 installation end and handspike bearing 7 hinged, one end of drive end and latch hook 3 is hinged, middle part and the latch hook bearing 4 of described latch hook 3 are hinged, the other end of latch hook 3 rotates rear compression back door 1, along the intrinsic sealing joint strip 2 of the circumferential glue in back door 1.
The power supply on the power acquisition waste-skip chassis 6 of described electric pushrod 5.
Described latch hook 3 is " 7 " font, and the one end compressing back door after rotating is semicircular structure.
Described sealing joint strip 2 is round outside but spuare inside through-hole structure.
Described latch hook 3 becomes " 7 " font structure by jam plate 9, backing plate 10, otic placode 11 assembly welding.
During locking work, electric pushrod 5 stretches out, and band moveable lock hook 3 is around latch hook bearing 4 counter-clockwise swing, and latch hook 3 utilizes the semicircular structure incision of end and compresses back door 1, sealing joint strip 2 is deformed, reaches positiver sealing and locking; Unblank work time electric pushrod 5 regain, band moveable lock hook 3 swings around latch hook bearing 4 cw pin, latch hook 3 is unclamped, away from back door 1, realizes unlocking.
Described electric pushrod 5 is prior art.
The utility model not only can be applied and small-sized sealing waste-skip, also may be used for the waste-skip of other type.
Above-described embodiment is unrestricted to explanation of the present utility model, is not departing from the change done under the prerequisite of impracticable new principle also within protection domain of the present utility model.
