[0029] A telescopic bed frame, as shown in Figures 1-8, includes a fixed frame 1 and a telescopic frame 2. The fixed frame 1 includes a plurality of fixed rods 11 extending along the length of the telescopic bed frame and a first support leg 12. The first support leg 12 is used to support the fixed rods 11. The telescopic frame 2 includes a telescopic rod 21 coaxially arranged with the fixed rods 11 and a second support leg 22. The second support leg 22 is used to support the telescopic rod 21. The telescopic rod 21 corresponds one-to-one with the fixed rod 11. The fixed rod 11 has an internal receiving space for accommodating the telescopic rod 21. The end of the fixed rod 11 near the telescopic rod 21 is... An opening 11a is provided to connect the accommodating space, allowing the end of the telescopic rod 21 near the fixed rod 11 to extend into the fixed rod 11 through the opening 11a. On the one hand, users can control the overall length of the bed frame by adjusting the extension length of the telescopic rod 21 into the fixed rod 11 according to actual needs, thereby meeting different user requirements. On the other hand, when the telescopic rod 21 is fully or partially retracted into the fixed rod 11, the overall length of the bed frame will be significantly reduced, thereby reducing the space occupied by the bed frame and facilitating its storage and transport.

[0030] In this embodiment, to improve the stability of the bed frame, the telescopic rod 21 and the fixed rod 11 are detachably connected by an adjustment structure 3. The adjustment structure 3 includes a sleeve 31 connected to the fixed rod 11 and a collar 32 that slides outside the telescopic rod 21. The sleeve 31 has an axial through hole 312 for the telescopic rod 21 to pass through. One end of the sleeve 31 near the collar 32 is provided with a closing portion 311. The outer radial direction of the closing portion 311 gradually increases towards the fixed rod 11, and the inner wall of the collar 32 is provided with a method for circumferentially pressing the closing portion 311 to force the closing portion 311 to retract inward and contact the fixed rod 11. When the inner wall of the retractable part 311 contacts the outer surface of the telescopic rod 21, the pressing part 321 of the telescopic rod 21 has a large static friction force, which fixes the telescopic rod 21. The pressing part 321 is annular and is located at the end of the sleeve 31 away from the inner wall of the collar 32. When fixing the telescopic rod 21, the operator controls the collar 32 to slide towards the sleeve 31 until the annular pressing part is gradually fitted onto the outer surface of the retractable part 311. When disassembling, the collar 32 is moved away from the sleeve 31 until the pressing part and the retractable part 311 no longer contact each other.

[0031] In this embodiment, in order to enable the retractable part 311 to retract smoothly inward and contact the telescopic rod 21, a plurality of notches 313 are formed on the retractable part 311. The notches 313 extend axially from the end of the sleeve 31 near the collar 32 towards the direction near the fixed rod 11, and the plurality of notches 313 are evenly spaced along the axial direction of the sleeve 31.

[0032] In this embodiment, the collar 32 and the sleeve 31 are threaded together. The inner wall of the collar 32 is provided with an internal thread, and the outer wall of the sleeve 31 is provided with an external thread that mates with the internal thread on the collar 32. The threaded connection between the collar 32 and the sleeve 31 can improve the connection strength between the sleeve 31 and the collar 32, thereby improving the stability of the bed frame. On the other hand, it helps to improve the assembly efficiency of the bed frame in terms of operation.

[0033] In this embodiment, a connecting structure 4 is provided between the fixing rod 11 and the sleeve 31. The connecting structure 4 has a first through hole 41 coaxially arranged with the fixing rod 11.

The fixing rod 11 extends into the first through hole 41 and is detachably connected to the connecting structure 4.

[0034] It should be noted that the fixed rod 11 has a screw hole at one end near the telescopic rod 21. Therefore, the fixed rod 11 and the connecting structure 4 can be detachably connected by inserting a bolt through the screw hole from the outer surface of the connecting structure 4.

[0035] In this embodiment, a third leg 5 for supporting the connecting structure 4 is connected to the connecting structure 4, and a first connecting rod 6 is provided between two adjacent connecting structures 4. Specifically, the connecting structure 4 has a third through hole 43 for the first connecting rod 6 to extend into and a second through hole 42 for the third leg 5 to extend into, and the second through hole 42 communicates with the third through hole 43. A fastener 51 is provided at the top of the third leg 5, and a mounting hole 61 is provided at the end of the first connecting rod 6. The fastener 51 passes through the mounting hole 61 so that the first connecting rod 6 and the third leg 5 can be detachably connected. Here, the fastener 51 can be a bolt, and the mounting hole 61 is a threaded hole that is threadedly connected to the fastener 51.

[0036] In this embodiment, multiple fixed rods 11 are connected by a second connecting rod 13, and multiple telescopic rods 21 are connected by a third connecting rod 23. The second connecting rod is located at the end of the fixed rod 11 away from the telescopic rod 21, and the third connecting rod is located at the end of the telescopic rod 21 away from the fixed rod 11, which helps to improve the structural stability of the bed frame.
