Detailed Description

To further illustrate the concept of the present invention, the following embodiments of the present invention will be further described with reference to the accompanying drawings:

the locking device for the rear door of the large-sized shelter shown in the figures 1 and 2 comprises a cross rod 1, a vertical rod 2, a handle 3, a hook box 4 and a locking hook 5, wherein the cross rod 1 is rotatably fixed on the shelter door, the hook box 4 is arranged on a door frame, the square frame part in the figure 1 is shown as the door frame, and the quadrilateral part with the inner round angle is the shelter door. The locking hooks 5 are arranged at two ends of the cross bar 1, and as shown in fig. 4, the locking hooks 5 and the hook boxes 4 can be locked with each other; the upper end of the handle 3 is rotationally fixed on the cabin door, the handle 3 is provided with a first protruding connector 31, the cross rod 1 is provided with a second protruding connector 11, and two ends of the vertical rod 2 are rotationally connected with the first connector 31 and the second connector 11 respectively. The handle 3 is rotated to drive the vertical rod 2, so that the cross rod 1 rotates to drive the latch hook 5 to hook the hook box 4, thereby firmly sealing the cabin door,

in order to enable the locking hook 5 and the hook box 4 to be more tightly occluded, the vertical rod 2 can be arranged to be of a telescopic structure, the angle of the locking hook 5 is adjusted by adjusting the length of the vertical rod 2, and the degree of occlusion tightness is adjusted.

As the best setting mode of the vertical rod 2, the vertical rod 2 is divided into an upper part and a lower part, which are connected through the adjusting device 21, the upper part and the lower part of the vertical rod are in threaded connection with the adjusting device 21, and the thread directions are opposite, as shown in fig. 5, two threaded holes with opposite threads can be arranged at two ends of the adjusting device 21, the upper part and the lower part of the vertical rod 2 are connected with the adjusting device 21 through protruding screw rods, so that the length of the vertical rod 2 can be adjusted by twisting the adjusting device 21, of course, only one end of the adjusting device 21 can be provided with a threaded hole, and the setting mode can be freely adjusted. In order to facilitate the twisting of the adjusting device 21, a wrench adjusting portion 22 is provided at the middle thereof, and the shape is selected according to the shape of the wrench used.

As shown in fig. 3, the shape of the latch hook 5 is set, the latch hook 5 is in a shape of "6", and is fixed on the cross bar 1 through a larger circular part, and the radian of the hook part is gradually reduced outwards, so that when the latch hook 5 rotates, the latch hook 5 and the hook box 4 are gradually occluded and sealed, not only can a better sealing effect be achieved, but also the force required by the sealing process can be reduced. The hook box 4 may be provided with a rod inside which the opening of the hook 5 can be engaged, so that the hook 5 is engaged and locked with the rod through the opening, or a protrusion matching with the opening of the hook 5 is provided in the hook box 4.

Preferably, the cross bar 1 is fixed on the cabin door through four movable points, and through four-point fixation, the best fixation effect is achieved, and the device structure can be prevented from being more complicated.

In order to prevent the door from being opened in the moving process, the door is also provided with a locker 6, the locker 6 only needs to be capable of fixing the pull handle 3, and a lock catch capable of penetrating through the opening is arranged on the door through the opening in the middle of the pull handle 3 as shown in figures 6 and 7, and is locked by a bolt or a padlock.

When the cabin door is closed, the handle 3 is pulled upwards firstly, then the cabin door is pushed, the lock hook 5 is pushed into the hook box 4, then the handle 3 is pulled downwards, the handle 3 pulls the vertical rod 2 through the force arm to drive the cross rod 1 to rotate, further the lock hook 5 is meshed on the hook box 4, along with the gradual downward pulling of the handle 3, the lock hook 5 is meshed more and more tightly until the cabin door is completely closed, and finally the handle 3 is fixed through the locker 6, so that the sealing in the transportation process of the cabin door is realized.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art can make various modifications and changes, and any modifications, equivalent replacements, improvements, etc. made by using the present invention should be included in the protection scope of the present invention.
