Abstract

The utility model discloses a garbage freight box with a self-locking and self-unlocking function and relates to the technical field of the structure of a garbage freight truck, in particular to the opening and closing structure of a discharging door of a garbage can of the freight truck. The upper end of the door is hinged to a box body, an oil cylinder is arranged between the box body and the door, and one end of the oil cylinder is hinged to the door; the garbage freight box is characterized in that a locking hook is hinged to the box body, and the other end of the locking hook is provided with a hook head which is hinged to the other end of the oil cylinder through a pin shaft in the middle of the locking hook; a door pin matched with the hook head is arranged on the door, a cylindrical support is arranged on the box body under a hinged point of the locking hook and the box body, and the locking hook is located above the cylindrical support. A connecting lock between the box body and the door does not need to be opened or closed manually, the door can be opened or closed by controlling the oil cylinder to operate, working conditions of sanitation workers are effectively improved, working efficiency is improved, and secondary pollution to a city during the freighting process of garbage is avoided.

Description

There is self-locking and open the garbage container of function

Technical field

The utility model relates to the technical field of structures of refuse collection trucks, particularly the construction of switch technology of the Dump gate of the rubbish container of transporting something containerized car.

Technical background

Existing refuse collection trucks is provided with at the rear portion of casing the chamber door that can open mostly, in order to prevent that vehicle from causing leakage in transportation road, need to chamber door be connected on casing securely by lock body, for the rubbish in unloader box, need first to open the latch fitting between chamber door and casing, and then adopt artificial or oil cylinder unlatching chamber door.

Because existing above structure needs artificial open and close latch fitting, operative employee's working environment is very severe, is unfavorable for improving the work treatment of operation element.

Utility model content

The utility model object is to design a kind of without manually opened and close the garbage container that function is opened in self-locking that has of the door lock that is connected between chamber door and casing.

The utility model arranges chamber door at the rear side of casing, the upper end of chamber door is hinged and connected on casing, between casing and chamber door, oil cylinder is set, one end and the chamber door of described oil cylinder are hinged, it is characterized in that on casing hinged one hook of locking a door, the other end of hook of locking a door is gib head, and the other end at the middle part of the hook of locking a door by bearing pin and described oil cylinder is hinged; On chamber door, arrange on the door coordinates with gib head and sell, on the casing below the hinged point of lock a door hook and casing, cylindricality base body is set, described in the hook of locking a door be positioned at above cylindricality base body.

When needs are opened chamber door, oil cylinder job control piston rod is overhanging, because of the deadweight of chamber door, the cylinder body hook hinged point on casing of locking a door under counter-force effect is clockwise rotated, and makes gib head throw off the upper pin of door, and is held on cylindricality base body; The oil cylinder piston rod that works on promotes chamber door around the hinged some rotation of chamber door and casing, thereby opens chamber door.When needs are closed chamber door, cylinder piston rod retraction, chamber door is automatically closed under its gravity, oil cylinder works on, cylinder body is carried under fluid power effect, drives the hook hinged point on casing of locking a door to rotate counterclockwise, and makes upwards operation of gib head, by the gib head and the upper mating reaction of selling of door of the hook of locking a door, thereby further chamber door is lock onto on casing.

The utility model is without the lock that is connected of manually opening or closing between casing and chamber door, only need by controlling the work of oil cylinder, just can realize and open or close chamber door, effectively improved sanitationman service conditions, increase work efficiency, stop the secondary pollution that collecting refuse process produces city, the work for the treatment of that makes municipal refuse is health, civilization more.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 be in Fig. 1 A portion when chamber door and casing enlarged drawing when sealed.

The specific embodiment

As shown in Figure 1, 2, the utility model is hinged chamber door 3 by rotating shaft 2 on the doorframe of the rear side upper end of the casing 1 of refuse collection trucks.

On casing 1, by a bearing pin 8 hinged hook 7 of locking a door, the other end of the hook 7 of locking a door is gib head 9, at the middle part of the hook 7 of locking a door, by bearing pin 6 and one end of oil cylinder 4, is hinged, and the other end of oil cylinder 4 is hinged by bearing pin 5 and chamber door 3.

On chamber door 3, arrange on the door coordinating with gib head 9 and sell 10, on the casing 1 below bearing pin 8, be fixedly installed cylindricality base body 11, the hook 7 of locking a door is positioned at the top of cylindricality base body 11.

Claims
