[0034] See also Figure 1-5 The present invention provides an assembled steel component that is easy to assemble, including a first steel body 1, a second steel body 2 and a connecting block 3, wherein at least one mounting groove 4 is respectively provided at both ends of the first steel body 1 and the second steel body 2, and a limiting block 5 is rotatably connected in the mounting groove 4, and a first limiting groove 51 is provided on the limiting block 5, and a connecting hole 6 is provided in the connecting block 3, and the ends of the first steel body 1 and the second steel body 2 are respectively inserted into the opposite ends of the connecting hole 6, and a plurality of limiting components 7 are respectively provided on both sides of the connecting block 3, and a first through hole 8 corresponding to the limiting component 7 is provided on the connecting block 3, and a second limiting groove 9 is respectively provided on both sides of the first through hole 8, and the second limiting groove 9 is located on the inner wall of the connecting block 3, and a locking component 10 is provided at the upper end or the lower end of the connecting block 3. When the limiting block 5 is rotated into the second limiting groove 9, one end of the locking component 10 is inserted into the first limiting groove 51.

[0035] The limiting component 7 includes a first knob 71, a spring 72, and an inserting block 73. The first knob 71 is movably connected to the first through hole 8. One end of the spring 72 is connected to the first knob 71, and the other end of the spring 72 is connected to the inserting block 73. The inserting block 73 and the spring 72 are located in the first through hole 8. The first knob is threadedly connected to the connecting block. By rotating the first knob, the inserting block can be driven to move back and forth, thereby pushing the limiting block to rotate and insert, so that the limiting block partially enters the second limiting groove and supports the limiting block to prevent it from moving, thereby achieving a clamping connection and fixation between the limiting block and the second limiting groove.

[0036] The end of the plug-in block 73 away from the spring 72 has an inclined surface to facilitate the movement of the plug-in block.

[0037] The connecting block 3 is provided with an installation cavity, in which the locking component 10 is installed, and the installation cavity is connected to the second limiting groove 9. The locking component 10 includes a second knob 101, a gear 102, and two racks 103. The second knob 101 is rotatably connected to the connecting block 3. The gear 102 is provided at the bottom of the second knob 101. The gear 102 is engaged with the rack 103. The rack 103 is slidably connected in the installation cavity. The end of the rack 103 away from the gear 102 is provided with a plug-in rod 104, which is plugged into the first limiting groove 51. When the second knob is turned, the second knob drives the gear to rotate, and then the gear drives the rack to move, causing the plug-in rod to enter the first limiting groove, thereby re-fixing the limiting block and preventing the limiting block from entering the installation groove on its own.

[0038] The plug-in rod 104 and the rack 103 are an integral structure, so that the plug-in rod is fixed more firmly.

[0039] The limiting block 5 is a semi-cylindrical structure. The second limiting groove 9 is an arc-shaped limiting groove, and the two second limiting grooves 9 are symmetrically arranged on both sides of the first through hole 8.

[0040] Working principle: When the first steel body and the second steel body are connected, the first steel body and the second steel body are connected through the connecting block, and the ends of the first steel body and the second steel body are respectively inserted into the connecting holes in the connecting block. When the first knob is turned, the spring is compressed and pushes the plug-in block to move. The plug-in block supports the limit block and pushes the limit block to rotate, so that the limit block partially enters the second limit groove. At this time, the second knob is turned, the second knob drives the gear to rotate, and then the gear drives the rack to move, so that the plug-in rod enters the first limit groove, so that the limit block can be fixed again to prevent the limit block from entering the installation groove by itself, so that the first steel body, the second steel body and the connecting block can be fixed more firmly. When disassembling, the second knob is reversed, the plug-in rod exits the first limit groove, and then the first knob is reversed, the plug-in block retreats to the first through hole, the first steel body and the second steel body are pulled outward again, and the limit block enters the installation groove, so that the first steel body and the second steel body can be quickly disassembled. Therefore, the structure of the present invention is simple and convenient to operate, can improve installation efficiency, and has stable connection.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
