Abstract
The utility model discloses a self-fastening door locking mechanism, which comprises an oil cylinder fixing seat, an oil cylinder, an oil cylinder connecting pin, a bolt, a bolt guide plate and a bolt slot mechanism, wherein the oil cylinder fixing seat is fixed on a dustbin upright post; one end of the oil cylinder is connected with the oil cylinder fixing seat via the connecting pin while the other end thereof is connected with the bolt via a pin shaft; the bolt guide plate is fixed on the dustbin upright post; one end of the bolt is connected with the oil cylinder while the other end thereof is made into the shape of a wedge; and one end of the bolt slot mechanism is fixed on the dustbin door upright post while a pulley is arrange at the other end. Combined with hydraulic control, the utility model realizes the self-fastening of the dustbin door, thereby avoiding dripping or leakage of dirt and sewage water, and ensuring the sealing effect even in the case of abrasion caused by the use.
Description
Technical field
The utility model relates to environmental sanitation rubbish transferring equipment field, relates in particular to a kind of back door of rubbish bin catch gear.
Background technology
The rubbish transferring equipment is mainly used in house refuse concentrated and is transported to rubbish and finally handles the field.In transportation, the chest that loads rubbish causes secondary pollution problems such as rubbish is scattered, sewage drippage usually because back door locking is not tight, brings on the way the common people's living environment and has a strong impact on.Traditional back door catch gear is a kind of to be to utilize the track difference of mechanical movement to realize auto lock, the seal degree of back door and rubbish container casing is just determined in manufacturing process, along with the increase of period of service, wearing and tearing such as sealing member, seal clearance strengthens, and causes lock sealing to lose efficacy.The another one problem is to adopt manual locking to open, and vehicle is when the garbage disposal plant, and environment is abominable, and the people gets off manually opened just cumbersome.
Summary of the invention
The purpose of this utility model provides a kind of door locking device of buckled up back door of rubbish bin automatically, prevents the drippage of dirt sewage, avoids opening manually or closing, and can not cause seal failure because using wearing and tearing.
The purpose of this utility model technical scheme is: a kind of automatic fastening lock door mechanism is provided, comprises oil cylinder permanent seat, oil cylinder, connecting pin, latch, latch guide plate, latch groove mechanism, described oil cylinder permanent seat is fixed on the rubbish container column; Described oil cylinder one end is connected with the oil cylinder permanent seat by connecting pin, and an end is connected with latch by bearing pin; Described latch guide plate is fixed on the rubbish container column, and the centre is provided with opening.
Further, described latch one end is connected with oil cylinder, and the other end is made wedge, and described latch passes latch guide plate middle opening.
Further, be provided with opening in the middle of the described latch groove mechanism, an end is fixed on the suction garbage can door body column, and the other end is provided with pulley.
At work, rubbish container is placed on the torque arm car by the control of torque arm car, when rubbish container falls, behind the return of back door, control the fluid control bar on the torque arm car, under the effect of high-voltage oil liquid, the oil cylinder piston bar stretches out, and latch moves down under the oil cylinder effect, put in the opening of latch groove mechanism, because wedge is made in the latch lower end,, fit tight more with the pulley on the latch groove mechanism along with the lengthening that advances length deeply, suction garbage can door is pulled to the rubbish casing, realizes the fastening sealing purpose.When rubbish is dumped at needs unlatching back door, oppositely control the fluid control bar on the torque arm car, the oil cylinder piston bar is regained, and latch moves up, and deviates from the opening of latch groove mechanism, makes the back door break away from locking-in state, just can freely open.
Because after having adopted the utility model, the back door of rubbish container can be unlocked or close automatically, the inconvenience of having avoided the manual operation of people to bring, and because latch adopts the wedge shape, can automatically regulating the locking distance, make when closing and casing remains the state that fits tightly.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Be described further this reality is novel below in conjunction with accompanying drawing.
In the drawings: 1, rubbish casing column; 2, latch guide plate; 3, latch; 4, oil cylinder; 5, back door; 8, pulley; 9, oil cylinder permanent seat; 10, latch groove mechanism.
At work, rubbish container is placed on the torque arm car by the control of torque arm car, when rubbish container falls, behind 5 returns of back door, control the fluid control bar on the torque arm car, under the effect of high-voltage oil liquid, oil cylinder 4 piston rods stretch out, and latch 3 moves down under oil cylinder 4 effects, put in the opening of latch groove mechanism 10, because it is latch 3 lower ends make wedge,, tight more with pulley 8 on the latch groove mechanism 10 along with the lengthening that advances length deeply, back door of rubbish bin 5 is pulled to the rubbish casing, realizes the fastening sealing purpose.When rubbish is dumped at needs unlatching back door 5, oppositely control the fluid control bar on the torque arm car, oil cylinder 4 piston rods are regained, and latch 3 moves up, and deviates from the opening of latch groove mechanism 10, makes back door 5 break away from locking-in states, just can freely open.
