[0026] Referring to Figures 2 to 8 , the utility model discloses a kind of front end frame openable containers, including box body 1, front end frame 2 and rear end unloading door 3, front end frame 2 is installed with cold machine.
[0027] Referring to Figure 2 , in the embodiment, front end frame 2 is set at the front end of box body 1 by three groups of hinge assemblies 4, and the three groups of hinge assemblies 4 are distributed along the height direction of box body 1, and are all double-shaft hinges, the side edge of front end frame 2 is connected to one side of side plate 11 of box body 1 by double-shaft hinge. Each group of double-shaft hinge includes end frame hinge plate, connecting hinge plate and side plate 11 hinge plate connected by hinge shaft in turn, end frame hinge plate is welded and fixed to the side edge of front end frame 2, and side plate 11 hinge plate is welded and fixed to the side edge of side plate 11.
[0028] In combination with Figure 3 , Figure 6 and Figure 7 , four corners of front end frame 2 are provided with corner pieces 21, and the corner pieces 21 are connected with the top side beams or bottom side beams of box body 1 by twist locks, the twist lock includes an adjusting mechanism, a lock rod and a lock head, the lock head and the lock rod are integrated, the lock rod is fixed axially to the top side beam or the bottom side beam, and the adjusting mechanism is connected to the lock rod by a transmission assembly commonly used in the mechanical field to control the rotation of the lock head between the horizontal position and the vertical position.
[0029] The embodiment utilizes the two position states of the lock head to cooperate with the corner pieces 21 to control the opening and closing of front end frame 2: when the lock head is in the horizontal position, the lock head can freely enter and exit the corner piece 21, that is, the front end frame 2 can be freely opened without restriction; when the front end frame 2 is closed at the front end of box body 1, the lock head enters the inside of the corner piece 21, and the lock head can be rotated to the vertical position by the adjusting mechanism, so as to be relatively locked with the corner piece 21, and the front end frame 2 is closed,
[0030] The twist lock in the embodiment can be a press type twist lock, and the button is the adjusting mechanism, the press type twist lock is installed at the end of the two top side beams and the two bottom side beams, and the position of the lock head can be switched by pressing the button, and the horizontal position and the vertical position of the lock head correspond to the unlocking state and the locking state respectively. In the press type twist lock, the lock head automatically returns to the locking state when the button is released, at this time, the lock head is in the vertical position and cannot be separated from the corner piece 21, so as to ensure that the front end frame 2 is closed and cannot be opened; when the button is pressed, the lock head is in the horizontal position of the unlocking state, at this time, the front end frame 2 can be freely opened.
[0031] Based on the openable structure of the front end frame 2, the sealing structure and the strength structure are additionally provided in the present example, referring to Figure 5 、 Figure 6 and Figure 8 :
