Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.
Referring to fig. 1 to 3, the height adjusting structure of the protective door for opening 1 of the present invention comprises a door plate, a supporting cross bar 3, a fixing plate 4, an adjusting frame 5, an adjusting plate 6, etc. The door panel is arranged at the hole 1 of the main body structure 2. The upper and lower parts of the two side surfaces of the door plate are respectively and fixedly connected with a supporting cross rod 3, and each supporting cross rod 3 is inserted in an adjusting frame 5 at a corresponding position. Preferably the support rail 3 is of cylindrical construction.
The adjusting frame 5 is fixedly welded on the upper surface of the fixing plate 4, a bolt hole 8 is formed in the fixing plate 4, and the expansion bolt 7 penetrates through the bolt hole 8 to fix the fixing plate 4 and the main structure 2 together. The inner side wall of the lower end of the adjusting frame 5 is provided with a concave first bayonet 51, and the first bayonet 51 is used for clamping the supporting cross rod 3. Adjusting frame 5's inside is provided with adjusting plate 6, and adjusting plate 6 welds in fixed plate 4 upper surface, and the second bayonet socket 61 of indent is seted up to adjusting plate 6 upper end, and second bayonet socket 61 is used for clamping supporting cross rod 3. The distance from the inner side surface of the adjusting frame 5 to the outer side surface of the adjusting plate 6 is larger than the diameter of the supporting cross rod 3, so that the supporting cross rod 3 can smoothly move in a gap channel between the adjusting frame 5 and the adjusting plate 6. Preferably, the first bayonet 51 and the second bayonet 61 are groove structures with wide top and narrow bottom, so that the support rail 3 can be taken out smoothly. The adjusting frame 5 and the adjusting plate 6 are located in the same vertical plane, the position of the supporting cross rod 3 is limited, and the phenomenon that the supporting cross rod 3 cannot fall off in the moving process is guaranteed.
The use process comprises the following steps: when the structure body is constructed, the supporting cross rod 3 is clamped at the first bayonet 51, and the lower end of the door plate falls on the ground; when ground construction is carried out, the supporting cross rod 3 is lifted up from the first bayonet 51, moves along the gap channel and is clamped at the second bayonet 61, the door plate is lifted up to be separated from the ground, the ground engineering is guaranteed to be normally carried out, and potential safety hazards are eliminated.
Finally, it is noted that: the preferred embodiments of the present invention have been shown and described, and modifications and variations of the present invention may be made by those skilled in the art without departing from the scope of the present invention.
