Abstract
The utility model relates to a locking structure of a container door of an air container. The utility model with better safety performance can bear the working load of a main chamber type air container. The utility model comprises two metal doors, wherein the two metal doors are respectively connected with a container body through hinges. The utility model is characterized in that the surfaces of the metal doors are respectively provided with rotatable lock rods on one side that the two metal doors are jointed, both ends of the lock rods are respectively provided with cams, and axial leads of the cams are perpendicular to the metal doors; the container body is respectively provided with lock catches corresponding to positions of the cams when the metal doors are jointed, the diameter of a hole end of the lock catch is larger than the radial width of the cam and is smaller than the length of the cam, and the length of spaces in the lock catch is larger than the length of the cam; the lock rod is connected with a rotatable handle, and the metal doors are respectively provided with closure buckles on abutted positions of the handle and the metal doors.
Description
(1) technical field
The utility model relates to air equipment, is specially the locking mechanism of air mode container chamber door.
(2) background technology
Up to the present the air mode container of enterprise's Development and Production of China all is the air mode container of cargo hold.The locking mechanism of freight container chamber door is seen Fig. 1, it comprises metallic door, the upper end of metallic door is connected with container body by hinge 1, the lower end of metallic door (3 places, position insert in the casing of freight container among Fig. 1), the centre is connected with the casing of freight container by two door bolt bars 2, like this, the suffered load and the bending moment of door of freight container mainly born by hinge 1 and two pin rods 2, this form is not fine under load that door bore and bending moment are not very big situation, for main cabin type air mode container, it for example highly is 81.5 inches air mode container, the height of its casing is 2070 millimeters, and the load that the one side of door is born is 8513 kilograms, under such condition, if metallic door also adopts hinge to add the form of two door bolt bars, the moment of flexure that so big load and this load produce will be difficult to bear.
(3) summary of the invention
Locking mechanism at existing air mode container door, it adopts hinge to add two door bolt bars, be difficult to bear bigger load, be not suitable for the shortcoming in the type air mode container of main cabin, used, the utility model provides the locking mechanism of another air mode container chamber door, it can bear the working load of main cabin type air mode container, and safety performance is better.
Its technical scheme is such: it comprises two fan metallic door, described two fan metallic door are connected with casing by hinge respectively, it is characterized in that: in the involutory side of two fan metallic door, the surface of described metallic door is separately installed with rotating locking bar, the two ends of described locking bar are separately installed with cam, the axial line of described cam is vertical with described metallic door, corresponding described metallic door is to the position of fashionable described cam, described casing is separately installed with snap close, the nose end diameter of described snap close is greater than the radial width of described cam, length less than described cam, space length in the described snap close is greater than the length of described cam, described locking bar is connected with rotary handle, described handle and metallic door card close the place, and described metallic door is separately installed with sealed button.
It is further characterized in that: described sealed deduction of points does not comprise a pair of rotary hasp, and every pair of involutory position of hasp is respectively arranged with lockhole, and every pair of hasp is to leaving the spacing that can settle handle between fashionable its inside face and the metallic door.
The utility model is applied to main cabin type air mode container, metallic door with and and casing between hinge and the common bearing load of locking bar that fastens with casing, load-carrying capacity is strong, the safety factor height, thereby avoided the locking mechanism of existing air mode container door, it adopts hinge to add two door bolt bars, is difficult to bear bigger load, is not suitable for the shortcoming of using in the type air mode container of main cabin.
(4) description of drawings
Fig. 1 is the structural representation of the locking mechanism of existing air mode container door;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the enlarged drawing at A place among Fig. 2.
(5) specific embodiment
See Fig. 2, the utility model comprises two fan metallic door, described two fan metallic door are connected with casing by hinge 4 respectively, in the involutory side of two fan metallic door, the surface of metallic door is separately installed with rotating locking bar 2 (see figure 3)s, the two ends of locking bar 2 are separately installed with cam 1, the axial line of cam 1 is vertical with metallic door, corresponding metallic door is to the position of fashionable cam 1, and casing 3 is separately installed with snap close 8, and the nose end diameter of snap close 8 is greater than the radial width of cam 1, length less than cam 1, space length in the lockhole 8 is greater than the length of cam 1, locking bar 2 is connected with rotary handle 5, and handle 5 closes the place with the card of metallic door, and metallic door is separately installed with sealed button.Described sealed deduction of points does not comprise a pair of rotary hasp 7,6, and every pair of involutory position of hasp is respectively arranged with lockhole, and every pair of hasp is to leaving the spacing that can settle handle between fashionable its inside face and the metallic door.Below in conjunction with Fig. 2 moving process of the present utility model is described: during unlatching, turn-off hasp 7,6, swing handle 5, handle 5 drives locking bar 2 and rotates, the cam 1 of locking bar 2 ends also and then rotates, when the axial line of cam 1 vertical with metallic door, pull handle 5, locking bar 2 drives cams 1 cam 1 is pulled out from lockhole 8.At closing time, course of action is with top opposite.
