DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides two technical solutions: specifically including the following embodiments:

[0020] Example 1

[0021] See also Figure 1-Figure 2 , a composite steel door that is easy to assemble, comprising an upper door body 1 and a lower door body 2, both of which are made of steel, and the upper door body 1 and the lower door body 2 are assembled and connected by a quick disassembly mechanism 3;

[0022] The quick disassembly and assembly mechanism 3 includes a plug plate 31 fixed on the top of the lower door body 2, a slot 32 matching the size of the plug plate 31 is opened at the bottom of the lower door body 2, the top of the plug plate 31 extends to the inside of the slot 32, a connecting plate 33 is arranged on one side of the upper door body 1, a handle 34 is fixed on one side of the connecting plate 33, a plurality of plug-in components 35 are arranged between one side of the connecting plate 33 and the upper door body 1, a plurality of circular grooves 36 are opened on one side of the plug plate 31, and the number of the plug-in components 35 and the circular grooves 36 are both set to five.

[0023] By setting up the quick disassembly and assembly mechanism 3, a quick disassembly and assembly connection between the upper door body 1 and the lower door body 2 is achieved. By dividing the steel door into two door bodies, the weight is reduced, which is convenient for one person to operate and meets the needs of quick installation and use.

[0024] Example 2

[0025] Based on Example 1, see Figure 3 As shown, the plug-in assembly 35 includes a plug post 351 fixed to one side of the connecting plate 33, and one end of the plug post 351 is set as an inclined surface.

[0026] The top of the plug plate 31 is in contact with and pressed against the inclined surface of the plug post 351 , and a transverse groove 352 is formed inside the upper door body 1 .

[0027] The transverse groove 352 is adapted to the size of the slot 32 , and one end of the plug post 351 passes through one side of the upper door body 1 and the transverse groove 352 and extends to the inside of the circular groove 36 .

[0028] A circular plate 353 is fixed to the outer surface of the plug post 351 , and the outer surface of the circular plate 353 is slidably connected to the inner surface of the transverse groove 352 .

[0029] A spring 354 is sleeved on the outer surface of the plug post 351, one end of the spring 354 is fixed to one side of the circular plate 353, and the other end of the spring 354 is fixed to the inner wall of the transverse groove 352. After the plug plate 31 is inserted into the slot 32, the plug plate 31 will contact and squeeze the inclined surface of the plug post 351, driving the plug post 351 to move into the transverse groove 352, and at the same time, the circular plate 353 squeezes and compresses the spring 354. The spring 354 in the compressed state accumulates force. When the plug post 351 is docked with the circular groove 36, the spring 354 resets and drives the plug post 351 to be inserted into the circular groove 36, thereby realizing the assembly connection between the upper door body 1 and the lower door body 2.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, the slot 32 on the upper door body 1 is aligned with the plug plate 31 on the lower door body 2, so that the plug plate 31 is inserted into the slot 32, and the plug plate 31 is further contacted and squeezed with the inclined surface of the plug column 351, so that the plug column 351 drives the circular plate 353 to squeeze the compression spring 354. When the plug column 351 is docked with the circular groove 36, the spring 354 is reset. When the spring 354 is reset, it drives the circular plate 353 and the plug column 351 to be inserted into the circular groove 36, thereby realizing the assembly connection between the upper door body 1 and the lower door body 2. When disassembly is required, pull the handle 34, so that the handle 34 drives the connecting plate 33 and the plug column 351 to move, and finally makes the plug column 351 slide out of the circular groove 36, and further pull out the upper door body 1 to realize disassembly.

[0032] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
