[0024] like Figure 2 , 4 As shown in Figure 5, the utility model provides a technical solution: preferably, the supporting mechanism 3 includes a side panel 34, a slide plate 32 is slidably inserted in the middle of the side panel 34, a screw rod 33 is threadedly inserted on one side of the side panel 34, a door panel groove 31 is fixedly installed on one side of the inner wall of the slide plate 32, a supporting rod 35 is rotatably installed on the outer surface of the side panel 34, a splicing mechanism 4 is fixedly installed on the top of the supporting mechanism 3, the splicing mechanism 4 includes a limiting plate 41, a pressing plate 43 is fixedly installed on the bottom of the limiting plate 41, a clamping groove 42 is opened between the top of the pressing plate 43 and the bottom of the limiting plate 41, the pressing plate 43 is fixedly installed on the top of the slide plate 32 of the supporting mechanism 3, the splicing mechanism 4 is connected to the top plate 5 through the clamping groove 42, and clamping grooves 51 are opened at both ends of the top plate 5.

[0025] The steel door frame splicing structure is roughly divided into five modules, namely, a base plate 1, a fixing mechanism 2, a supporting mechanism 3, and a top plate 5. The fixing mechanism 2 and the supporting mechanism 3 can be laid flat to form a plane, so that the steel door frame splicing structure can reduce the size of a single door frame, facilitate transportation, and quickly splice and install on site after arriving at the site, thereby improving efficiency. During installation, after placing the base plate 1 at a designated position, the side plates 34 at both ends are rotated, and the slide plate 32 is stretched to adjust the use height of the final door frame. After adjustment, the screw rod 33 is rotated to press and fix one side of the slide plate 32, so that the height of the door frame is fixed, and then the door panel is plugged into the door panel groove 31 for fixed installation. The splicing mechanism 4 for plugging the top plate 5 is located at the top of the slide plate 32, and the installation height of the top plate 5 is adjusted by adjusting the height of the slide plate 32. The top plate 5 is plugged into the clamping groove 42 through the clamping grooves 51 at both ends. Because the supporting mechanism 3 can be rotatably adjusted on the base plate 1, the supporting mechanism 3 can clamp the base plate 1, and then the supporting mechanism 3 is finally supported and fixed by the fixing mechanism 2, thereby completing the clamping installation of the top plate 5.

[0026] like Figure 3 As shown, the utility model provides a technical solution: preferably, the fixing mechanism 2 includes a support plate 23, a fixing groove 21 is opened on the support plate 23, and a pin 22 is inserted through the fixing groove 21 of the support plate 23, and the pin (22) is inserted into the bottom of the support rod (35) after passing through the fixing groove 21.

[0027] In this embodiment, the installation height of the top plate 5 is adjusted by adjusting the height of the slide plate 32. After the top plate 5 is inserted into the clamping groove 42 through the clamping grooves 51 at both ends, the support rod 35 installed on the outer surface of the side plate 34 is turned over, so that one end of the bottom is overlapped on one side of the support plate 23, and the hole of the support rod 35 corresponds to the fixing groove 21 opened on the support plate 23. Then the pin 22 passes through the support plate 23 and is inserted into the hole at the bottom of the support rod 35 of the support mechanism 3, so that the fixing mechanism 2 and the supporting mechanism 3 form a triangular stabilizing mechanism. The fixing mechanism 2 plays a stabilizing supporting role for the steel door frame splicing structure, increases the overall strength of the door frame and prevents deformation or loosening. The steel door frame splicing structure can be transported to the site for installation after being prefabricated in the factory, and the splicing structure can reduce the size of a single door frame, facilitate transportation, and simplify the on-site installation process to improve efficiency.

[0028] The following is a detailed description of the working principle of the steel door frame splicing structure.

[0029] like Figure 1-5As shown, the steel door frame splicing structure is roughly divided into five modules: a base plate 1, a fixing mechanism 2, a supporting mechanism 3, and a top plate 5. The fixing mechanism 2 and the supporting mechanism 3 can be laid flat to form a plane, so that the steel door frame splicing structure can reduce the size of a single door frame, which is convenient for transportation. After arriving at the site, it can be quickly spliced ​​and installed on site to improve efficiency. During installation, after placing the base plate 1 at a designated position, the side plates 34 at both ends are rotated, and the slide plate 32 is stretched to adjust the final use height of the door frame. After adjustment, the screw rod 33 is rotated to press and fix one side of the slide plate 32 so that the height of the door frame is fixed, and then the door panel is plugged into the door panel groove 31 for fixed installation. The splicing mechanism 4 for plugging the top plate 5 is located at the top of the slide plate 32. The installation height of the top plate 5 is adjusted by adjusting the height of the slide plate 32. The top plate 5 is plugged into the clamping groove 42 through the clamping grooves 51 at both ends. Because the supporting mechanism 3 can be rotatably adjusted on the base plate 1, the supporting mechanism 3 can clamp the base plate 1, and then the Finally, the supporting mechanism 3 is supported and fixed by the fixing mechanism 2, thereby completing the clamping installation of the top plate 5, and adjusting the installation height of the top plate 5 by adjusting the height of the slide plate 32. After the top plate 5 is inserted into the clamping groove 42 through the clamping grooves 51 at both ends, the supporting rod 35 installed by rotating the outer surface of the side plate 34 is flipped, so that one end of the bottom is overlapped on one side of the support plate 23, and the hole of the supporting rod 35 corresponds to the fixing groove 21 opened on the support plate 23, and then the pin 22 is inserted into the hole at the bottom of the supporting rod 35 of the supporting mechanism 3 after passing through the support plate 23, so that a triangular stabilizing mechanism is formed between the fixing mechanism 2 and the supporting mechanism 3, and the fixing mechanism 2 plays a stabilizing supporting role for the steel door frame splicing structure, increases the overall strength of the door frame and prevents deformation or loosening. The steel door frame splicing structure can be transported to the site for installation after being prefabricated in the factory, and the splicing structure can reduce the size of a single door frame, facilitate transportation, and also simplify the on-site installation process to improve efficiency.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
