Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole specification sheets and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or component part, and do not get rid of other element or other component part.
As shown in Figures 1 to 4, according to the carriage back door latching device of a kind of rubbish van of the specific embodiment of the invention, this latching device comprises: latch hook 6, three fastening parts, actuating device 3 and limiting stoppers 15 under upper latch hook 4, lower latch hook 5, door; Under upper latch hook 4, lower latch hook 5 and door latch hook 6 along on compartment 1 under thereon hinged successively, and be interconnected by link gear, to make under latch hook 4, lower latch hook 5 and door latch hook 6 can action simultaneously, more specifically, link gear comprises long connecting rod 10, short connecting rod 11, pull bar 12 and dwang 14, long connecting rod 10 is articulated with between latch hook 4 and lower latch hook 5, the below of lower latch hook 5 is fixed in one end of pull bar 12 and dwang 14 by a rotating shaft 13, the other end and the short connecting rod 11 of pull bar 12 are hinged, and under the other end of dwang 14 and door, latch hook 6 is hinged; Carriage back door 2 is provided with three fastening parts matched with latch hook 6 under upper latch hook 4, lower latch hook 5 and door respectively, and three fastening parts are respectively snap close 9 under the first lock pin 7, second lock pin 8 and door; Actuating device 3 is articulated with between carriage back door 2 and upper latch hook 4 respectively, and in this embodiment, actuating device 3 is hydraulic ram.As decision design, carriage back door 2 is established in L-type, is installed on the top in compartment 1, when driving carriage back door 2 to open, because the fulcrum of carriage back door 2 Unscrew changes, the angle that carriage back door 2 can be made to open is larger, does not have the phenomenon that carriage back door 2 blocks the rubbish that comes down in torrents.Wherein, when latch hook 6 departs from fastening part under actuating device 3 driving upper latch hook 4, lower latch hook 5 and door, carriage back door 2 can be driven afterwards to open; When actuating device 3 drives carriage back door 2 cut out to put in place, latch hook 4 can be driven afterwards, lower latch hook 5 blocks with fastening part mutually with latch hook under door 6, action is carried out to carriage back door 2 and three latch hooks by a hydraulic ram 3, if carriage back door 2 locks the leakage phenomenon of generation not in place when avoiding three latch hooks and carriage back door 2 separately to drive simultaneously.
For making latch hook angle when opening more reasonable, below upper latch hook 4, a limiting stopper 15 is established in a distance, for carrying out rotary stopper to upper latch hook 4, when upper latch hook 4 is rotated down certain angle, will carry out spacing for limited piece 15.
For making tightness better, the conjunction closed end mouth respectively between compartment 1 and carriage back door 2 is provided with sealing band, and sealing band can adopt trapezoidal sealing band, multi-layer sealed bar etc.
Latching device is set to two, is located at carriage back door 2 both sides respectively, can reach 6 lockings, bilge water resisting seepage, 6 are uniformly distributed, and locking effect is good.
As shown in Figure 4, during use, hydraulic ram 3 works, and in drive, latch hook 4 rotates around fulcrum, until limited piece 15 spacing, upper latch hook 4 drives lower latch hook 5 to rotate around fulcrum by long connecting rod 10, and make, lower latch hook is separated with first, second lock pin.While lower latch hook 5 rotates, pull bar 12, dwang 14, rotating shaft 13 also rotates around fulcrum simultaneously, and under driving door, latch hook 6 rotates around fulcrum, and under making door, latch hook 6 is separated with snap close under door 9.Then carriage back door 2 rotates around back door hanger, until oil cylinder stroke is covered, back door is opened completely.On the contrary, after hydraulic ram 3 drives carriage back door 2 to put in place around back door hanger rotary closing, then close and close, latch hook 6 under lower latch hook and door, safe and reliable.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
