However, current L-shaped connection structures have some problems in practical applications, especially poor connection stability. Since metal components are subjected to various external forces during use, such as tension, compression, and bending, insufficient stability of the connection structure can easily lead to loosening, deformation, or even breakage, thus affecting the normal operation and service life of the mechanical equipment.

[0005] Therefore, one objective of this utility model is to propose a metal component connection structure to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a metal component connection structure, including a horizontally arranged first metal plate, an assembly plate inserted into one end of the first metal plate, a vertically arranged second metal plate fixedly connected to one end of the assembly plate, the end of the first metal plate near the assembly plate being in contact with the second metal plate, a first L-shaped connecting plate being provided between the first metal plate and the second metal plate, the side and bottom surfaces of the first L-shaped connecting plate being in contact with the first metal plate and the second metal plate respectively, and screws being fixedly connected to the side and bottom surfaces of the first L-shaped connecting plate. The screws are slidably connected to the first metal plate and the second metal plate respectively. Each screw has a nut threaded to its threaded portion. A second L-shaped connecting plate is slidably connected between the two screws. Both nuts are in contact with the outer surface of the second L-shaped connecting plate. Locking frames are slidably connected to the outer surfaces of the first metal plate and the second metal plate. Two symmetrically arranged bolt fasteners are rotatably connected to one side of each locking frame. The first L-shaped connecting plate and the second L-shaped connecting plate are slidably connected to the locking frames. The two locking frames are fixedly connected to the first metal plate and the second metal plate respectively by bolt fasteners.

[0007] Preferably, in any of the above solutions, the inner wall of the first L-shaped connecting plate is fixedly connected with two symmetrically arranged reinforcing ribs, and both the first metal plate and the second metal plate are perpendicular to the reinforcing ribs.

[0008] Preferably, in any of the above embodiments, the side and bottom surfaces of the second L-shaped connecting plate are provided with slots, and the screw portions of the two screws are slidably connected to the second L-shaped connecting plate through the two slots.

[0009] Preferably, in any of the above embodiments, the bottom surface of the first metal plate and the side surface of the second metal plate are both provided with through holes, and the two screws are slidably connected to the first metal plate and the second metal plate respectively through the through holes.

[0010] Preferably, in any of the above solutions, the inner wall of the locking frame is fixedly connected with a plurality of symmetrically arranged T-shaped connecting plates, and both ends of the first metal plate and the second metal plate are provided with T-shaped connecting grooves, and the T-shaped connecting plates are slidably connected to the first metal plate and the second metal plate through the T-shaped connecting grooves.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. When connecting metal parts, first place the first metal plate horizontally and insert the screw at the bottom of the first L-shaped connecting plate into the through hole. Then, take out the second metal plate and install it on one end of the first metal plate using the assembly plate until the inner side of the first metal plate is in contact with the side of the first L-shaped connecting plate. Then, assemble the second L-shaped connecting plate on the outside of the two metal plates. At this time, the screws of the two screws will pass through the two slots respectively. Then, screw the nuts onto the two screws until the two nuts are in contact with the outer surface of the second L-shaped connecting plate. The two metal plates can be initially assembled. Then, put the two locking frames on the first metal plate and the second metal plate. Then, continue to push the locking frames until the T-shaped connecting plate is completely inside the T-shaped connecting slot.

Then screw the nuts 6 onto the two screws 5 until the two nuts 6 are in contact with the outer surface of the second L-shaped connecting plate 7. The two metal plates can be initially assembled.

[0031] 3): Fit the two locking frames 8 onto the first metal plate 1 and the second metal plate 3, and then continue to push the locking frames 8 until the T-shaped connecting plate 13 is completely inside the T-shaped connecting groove 14. Then use the bolt fasteners 9 to lock the locking frames 8, which can complete the locking connection between the two metal plates.

[0032] In summary, this metal component connection structure, when connecting metal components, firstly, the first metal plate 1 is placed horizontally, and the screw 5 at the bottom of the first L-shaped connecting plate 4 is inserted into the through hole 12. Then, the second metal plate 3 is taken out and installed on one end of the first metal plate 1 through the assembly plate 2 until the inner side of the first metal plate 1 is in contact with the side of the first L-shaped connecting plate 4.
