[0016] Please see Figures 1-9One embodiment of this utility model is an assembled and spliced ​​iron bed frame, including long legs 2 and track tubes 7, wherein the track tubes 7 are fixedly connected to one side of the long legs 2. A short support leg 4 is provided on one side of the track tube 7. A slotted sliding tube 5 is connected to the top of the track tube 7, and horizontal square tubes 6 are evenly connected between the slotted sliding tubes 5. Mounting holes 10 are evenly provided on the track tube 7. A crossbeam 8 that can be added is evenly connected between the top ends of the track tube 7, and a locking block 9 is evenly fixed at the bottom of the crossbeam 8, and the locking block 9 is connected to the mounting hole 10. The track tube 7 is uniformly provided with self-locking seats 11. Each self-locking seat 11 has a spring base 16 connected to one side. Each spring base 16 has a sliding block 14 slidably connected to one side. Each sliding block 14 has a lock head 12 fixed to one side. Each locking block 9 has a lock hole 13 on one side. The lock head 12 and the lock hole 13 are connected. Each self-locking seat 11 has a slide rod 17 uniformly fixed inside. Each of the two sets of self-locking seats 11 has an unlocking seat 15 sleeved on the outside. The unlocking seat 15 is connected to the self-locking seat 11. Specifically, such as Figure 4 and Figure 7 As shown, in use, the short support leg 4 is installed on one side of the track tube 7, the slotted sliding tube 5 is connected to the top of the track tube 7, and then the horizontal square tube 6 is evenly connected between the slotted sliding tubes 5. Next, the optional cross frame 8 is connected to the top of the track tube 7, so that the locking block 9 is connected to the mounting hole 10. Inside the track tube 7, the self-locking seat 11 cooperates with the spring base 16, the sliding block 14, the lock head 12 and the slide rod 17 to realize the self-locking connection between the locking block 9 and the lock hole 13. The unlocking seat 15 is used for unlocking operation. The assembly is simple and convenient, the structure is stable, and the self-locking and unlocking can be completed quickly. It is convenient to adjust the range of use and improve the convenience of operation. The bottom cross-section of the locking block 9 is arc-shaped, and the inner cross-section of the lock head 12 is inclined. Specifically, such as Figure 3 and Figure 8 As shown, during use, the bottom of the locking block 9 is arc-shaped, which makes it easy to align with the mounting hole 10 at the top of the track tube 7 and insert smoothly. This design makes the installation and disassembly operations more convenient and improves the stability and reliability of the connection. The headboard 1 is fixed to the top of the long support leg 2, and a protective cover is provided on the outside of the headboard 1. A reinforcing rib 3 is fixed between the long support leg 2 and the track tube 7, and the cross section of the reinforcing rib 3 is triangular. Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, in use, the headboard 1 is fixed to the top of the long support leg 2, and then a protective cover is put on the outside of the headboard 1. Then, a reinforcing rib 3 with a triangular cross section is fixed between the long support leg 2 and the track tube 7. This can increase safety and aesthetics through the protective cover, and improve the stability and load-bearing capacity of the structure by using the triangular reinforcing rib 3.
