The adjustment mechanism 32 includes an adjustment screw 28 that penetrates the frame body 1 and the moving link 3. The number of the adjustment screws 28 can be customized according to needs. In this embodiment, the number of the adjustment screws 28 is two, and the plug rod 31 is provided with a plurality of screw holes 27 along its own length direction. The number of the screw holes 27 can be set according to the number of gears that need to be adjusted. In this embodiment, the distance between the frame body 1 and the moving link 3 can be adjusted in three gears. For this reason, the number of the screw holes 27 on a single plug rod 31 is four. The adjustment screw 28 can be threadedly connected to the frame body 1 and / or the plug rod 31 to achieve the fixed distance between the moving link 3 and the frame body 1.

[0037] The implementation principle of the telescopic bed frame structure of the first embodiment of the present application is: by unscrewing the adjusting screw 28, the distance between the movable connecting rod 3 and the frame body 1 can be adjusted to a suitable position, and then the adjusting screw 28 is screwed in to adapt to the changed width of the bed head.

[0038] Embodiment 2:

[0039] Embodiment 2 of the present application discloses a telescopic bed frame structure, referring to Figure 2 , which is different from the first embodiment, is that the adjustment mechanism 32 includes a driving member 38 located inside the frame body 1 and the insertion rod 31. The driving member 38 may be in a rectangular tube shape and its length direction is consistent with the length direction of the insertion rod 31. The driving member 38 is provided with a pin 25 at one end away from the insertion rod 31, and a cotter pin 26 is inserted into the pin hole of the pin 25, so that the driving member 38 and the frame body 1 are not easy to move relative to each other. A lead screw 39 is sleeved and threadedly connected at one end of the driving member 38 away from the pin 25. The lead screw 39 is located inside the driving member 38 and is rotatably connected to a sliding member 22 at one end. The sliding member 22 is slidably connected to the inner wall of the driving member 38 along the length direction of the driving member 38, so that the insertion rod 31 moves stably and is not easy to shake.

[0040] Reference Figure 2The two plug rods 31 are each detachably connected to a gear box 23 near the moving connecting rod 3. The interior of the gear box 23 can be in the form of two meshing bevel gears or worm gears, so that the input shaft and output shaft of the gear box 23 are perpendicular. The end of the lead screw 39 is coaxially detachably connected to the output shaft of the gear box 23. The output shafts of the two gear boxes 23 are coaxially fixedly connected with a synchronization rod 24. The length direction of the synchronization rod 24 is consistent with the length direction of the moving connecting rod 3. The synchronization rod 24 is located in the moving connecting rod 3. A power piece 21 is connected to the input shaft of a gear box 23, and the power piece 21 can also be connected to the synchronization rod 24. The power piece 21 can be a hand crank or a motor, and it only needs to be able to drive the input shaft of the gear box 23 to rotate.

[0041] In other implementations of this embodiment, the synchronization rod 24 may also be removed, and a power member 21 may be provided at the input shafts of the two gear boxes 23 .

[0042] The implementation principle of a telescopic bed frame structure in the second embodiment of the present application is: using the power member 21 to drive the screw 39 to rotate, so that the driving member 38 can move, so that the distance between the frame body 1 and the moving connecting rod 3 is changed accordingly to adapt to bed heads of different widths.

[0043] Embodiment three:

[0044] Embodiment 3 of the present application discloses a telescopic bed frame structure, referring to Figure 3 , which is different from the first and second embodiments, the adjustment mechanism 32 includes positioning columns 33 which are passed through and slidably connected to the inner walls on opposite sides of the insertion rod 31, and holes for the positioning columns 33 to be inserted into the inner walls of the frame body 1 for the insertion rod 31 to slide are provided. At the same time, an inter-column spring 34 is installed between the two positioning columns 33, and the inter-column spring 34 forces the two positioning columns 33 to move away from each other, so that when the movable link 3 is adjusted to a suitable gear position, the positioning column 33 can be inserted into the frame body 1, so that the position between the movable link 3 and the frame body 1 is fixed.

[0045] Reference Figure 3 A control rod 35 is slidably connected to the connection between the insertion rod 31 and the movable connecting rod 3. The control rod 35 moves along the length direction of the insertion rod 31. The end of the control rod 35 away from the positioning column 33 is exposed, and the end of the control rod 35 close to the positioning column 33 is fixedly connected to a rod wedge 36. The two positioning columns 33 are fixedly connected to column wedges 37. The inclined surface of the rod wedge 36 is tightly attached to the inclined surface of the column wedge 37, so that when the control rod 35 is pressed, the rod wedge 36 can force the two column wedges 37 to approach each other, so that the two positioning columns 33 are no longer inserted into the frame body 1, and the insertion rod 31 can be moved at this time.

[0046] The implementation principle of the telescopic bed frame structure of the third embodiment of the present application is: by pressing the control rod 35, the distance between the movable connecting rod 3 and the frame body 1 can be adjusted to adapt to bed heads of different widths.
