Abstract
The invention discloses a sift-proof backdoor locking device of a compartment, which is characterized by comprising an opening-closing mechanism and a locking mechanism, wherein the opening-closing mechanism is fixed at the top of the compartment backdoor; the locking mechanism is arranged on movable porous plates on two sides of the lower combination place of the compartment backdoor; and the locking mechanism adopts a single cylinder structure locked by symmetrical bolts on left end and right end. The device has the advantages of simple structure, reliable action, low cost and the like.
Description
Technical field
The present invention relates to sanitation equipment, be specifically related to the anti-back door locking device that spills of collection transhipment special-use vehicles such as house refuse, changing food waste or swill.
Background technology
Door locking device comprised back door mechanism for opening/closing and latch mostly after existing compressed garbage transfer car(buggy) and changing food waste collecting cart etc. contained sewage object transhipment special-use vehicle; Wherein the back door mechanism for opening/closing generally is employed in two outsides, compartment a back door keying oil cylinder respectively is installed, and the keying oil cylinder also lays respectively at the outside in the back door to the hinged point of action at back door.Latch catch gear majority is employed in the bottom in two outsides, compartment a locking cylinder respectively is installed, and utilizes the flexible bolt mechanism that drives of oil cylinder, and movable latch plate and back door in the bolt mechanism are fixedly linked.The back door mechanism for opening/closing not only is responsible for the back door and is opened closure, goes back and latch catch gear combined action cooperation, makes that the rubber strip that is installed between back door and the compartment is compacted, thereby reaches the sift-proof purpose of box sealing.
Back door locking device like this has following shortcoming: 1) owing in two outsides in rubbish compartment mechanism for opening/closing and catch gear two cover oil cylinders need be installed; This just must widen the size of whole vehicle on Width; Under the situation of vehicle width restriction, restricted the loading expanded in volume of whole vehicle virtually.2) the needed oil cylinder stroke of back door mechanism for opening/closing in compartment is longer, and cost is higher.3) the back door mechanism for opening/closing in compartment and latch catch gear must minimumly be installed two hydraulic rams respectively, and in order to guarantee two synchronous interactions between the hydraulic ram, must on hydraulic tubing, increase necessary control valve body and element.The complexity and the manufacturing cost that make whole rubbish compartment install are all higher relatively.
Summary of the invention
The purpose of this invention is to provide a kind of back door mechanism for opening/closing simple in structure and latch catch gear, can effectively solve the anti-back door locking device that spills in compartment of prior art problem.
Technical scheme of the present invention is achieved in that
The anti-back door locking device that spills in compartment; Be characterized in: comprise mechanism for opening/closing and catch gear; Described mechanism for opening/closing is fixed on the top of carriage back door; Catch gear is installed between the removable orifice plate of both sides, junction under the carriage back door, and described catch gear adopts the single cylinder structure of right ends symmetry latch locking.
Above-described mechanism for opening/closing; Comprise fixed pin shaft, open and close oil cylinder, tumble bearing pin and motion bearing pin; An end that opens and closes oil cylinder is hinged on the stationary cylinder seat of car body top through fixed pin shaft; The other end is hinged on through the motion bearing pin on the cylinder seat of back header, and is hinged through the bearing pin of tumbling between back door and the compartment.
The above catch gear; Comprise locking cylinder, connect bearing pin, coulisse, wedge-shaped bolt and fixing orifice plate; The right ends of locking cylinder is connected with coulisse respectively; Wedge-shaped bolt is through on the chute of connecting pin axle mounting in coulisse, and fixedly orifice plate is two, is separately fixed between the removable orifice plate of both sides, junction under the carriage back door.
The anti-back door locking device that spills of the present invention has following characteristics:
1, simple in structure.This anti-back door mechanism for opening/closing that spills the back door locking device is installed in the top in compartment; The latch catch gear is installed in the junction of compartment and below, back door; Do not take the bulk on the vehicle-width direction, under the situation of gross vehicle width limitations, expanded the loading volume of vehicle relatively.
2, reliable in action.The mechanism for opening/closing of this device opens and closes the function except accomplishing the back door, can also the rubber strip that be installed in top between back door and the compartment be compressed.And the latch catch gear can also compress the rubber strip that is installed in bottom between back door and the compartment except the locking function of accomplishing the back door.Two mechanism's combineds action guarantee compressed garbage transfer car(buggy), meal kitchen or swill refuse collector etc. up and down; Make the transhipment special-use vehicle in transport process, be in air-tight state all the time; Stop to spill the secondary pollution that causes, guaranteed the sanitation and hygiene of transit vehicle along the road.
3, cost is low.Bolt-type catch gear of the present invention only need adopt single cylinder action, and a cover locking mechanism just can lock two locking points of the carriage back door left and right sides simultaneously, and accomplishing common catch gear needs two oil cylinders to move the locking effect that just can reach simultaneously.And simplify the internal structure of an organization and the mounting arrangements of hydraulic tubing, simultaneously for the user practices thrift the simplification that brings the mounting arrangements of mechanism and hydraulic tubing when cost has reduced oil cylinder quantity, for the user has practiced thrift cost.
