Description
Technical field
The present invention relates to compression dustbin manufacturing technology field, especially a kind of detachable compression dustbin.
Background technology
During compression dustbin load garbage, be by rubbish compressing mechanism, rubbish to be clamp-oned in rubbish container, to improve the load-carrying capacity of rubbish container.Therefore body and the front/rear door of compression dustbin all need there is enough intensity, the weight at the back door of rubbish container and stressed all larger.
Due to the weight at the back door of compression dustbin and stressed larger, therefore the catch gear at back door is required also highlyer, ，Ge manufacturer has designed multiple catch gear at present.As within on 06 27th, 2012, disclosed a patent No., be that ZL201120402551.2, name are called the patent of invention of " a kind of backdoor hydraulic locking mechanism of self lighting type rubbish container " and a patent No. of on 06 27th, 2012 bulletins is that ZL200810021322.9, name are called the patent of invention of " device for opening and closing back door of rubbish bin ".These catch gears can meet the operating needs of garbage compression box substantially, but these catch gears power that its locking cylinder piston rod bears under closed condition at back door is larger, may there is hydraulic fluid leak in the piston rod of oil cylinder and sealing place of cylinder body, cause the stressed displacement of piston rod of oil cylinder, make automatically opening of garbage compression box below, so the reliability of these catch gear locking states needs further to be improved.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of detachable compression dustbin, and its back door switching motion is flexible, and the reliability of locking is higher.
For achieving the above object, technical scheme of the present invention is: a kind of detachable compression dustbin, comprise rubbish container body, back door, back door catch gear, described back door catch gear comprises two locking cylinders that are symmetricly set on rubbish container body both sides, two hammerlocks, two hangers are fixed in the upper end of both sides, back door, the rear upper end of two sides of rubbish container body arranges two jointed shafts, on described two hangers, be equipped with the hinged through hole of strip shape, described two hangers utilize the hinged through hole of strip shape to be enclosed within respectively on two jointed shafts, the rear lower interval of rubbish container body two sides is fixed with the first bearing pin and the second bearing pin, the middle part of two hammerlocks is hinged with two the first bearing pins respectively,
One end of two L shaped connecting rods is hinged with two the second bearing pins respectively, the other end of two L shaped connecting rods is hinged by the piston rod of two the 3rd bearing pins and two locking cylinders respectively, and the rear end of two locking cylinder cylinder bodies is hinged on respectively two sides of rubbish container body;
One end of two push rods is hinged by the middle part of two the 4th bearing pins and two L shaped connecting rods respectively, and the other end of two push rods is hinged by the front end of two the 5th bearing pins and two hammerlocks respectively;
The rear end of two hammerlocks is provided with groove and matches with two the 6th bearing pins that are fixed on back door two side lower parts respectively;
At least each fixes hook end latch hook down at the middle part, rear end, two sides of rubbish container body, and back door two middle side parts are fixed with the 7th bearing pin and match with described latch hook;
During two locking cylinder piston rod retractions, pass through L shaped connecting rod, push rod drives hammerlock clickwise to make the rear end groove of hammerlock depart from the 6th bearing pin and opens back door, when stretching out, pass through in two locking cylinder piston rods L shaped connecting rod, push rod drives hammerlock left-hand revolution that the rear end groove of hammerlock is withstood and on the 6th bearing pin, moves and make the 7th bearing pin and latch hook lock back door, after two locking cylinder piston rods stretch out and put in place, described the second bearing pin, the 4th bearing pin, the straight line that the center of the 5th bearing pin is linked to be on same straight line and with the 5th bearing pin center and the first bearing pin center is perpendicular.
Preferably described two locking cylinders are horizontally disposed with.Facilitate oil cylinder to install.
Further improve, the downside of the rear end groove of described each hammerlock is provided with an a linear portion and segmental arc obliquely and matches with described the 6th bearing pin, and the rear end of linear portion connects the front end of segmental arc.When the downside of guaranteeing each hammerlock rear end groove withstands the 6th bearing pin, the 6th bearing pin can not depart from the groove of hammerlock rear end, further improves the reliability of locking action.
Each fixes two hook ends latch hook down rear end, two sides middle part of preferred described rubbish container body, and back door two middle side parts are respectively fixed with that two the 7th bearing pins match with described latch hook.To increase coupling mechanism force.
Locking cylinder of the present invention drives hammerlock to rotate by L shaped connecting rod and push rod, and the activity space of hammerlock is larger, so its switching motion is flexible; On the other hand due to after two locking cylinder piston rods stretch out and put in place, the straight line that the center of described the second bearing pin, the 4th bearing pin, the 5th bearing pin is linked to be on same straight line and with the 5th bearing pin center and the first bearing pin center is perpendicular.When the weight at back door and the pressure bearing pass to hammerlock by the 6th bearing pin, the suffered power of hammerlock passes to rubbish container body by the 4th bearing pin and the second bearing pin, the piston rod of locking cylinder does not stress substantially, therefore the piston rod of oil cylinder just can not occur because of sealing place of piston rod and cylinder body that hydraulic fluid leak is shifted, guarantee that catch gear is in locking state, the reliability of door locking is higher thereafter.
