[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 6This utility model provides a technical solution: an adjustable height and length iron bed frame, comprising: a first iron bed frame 1; a second iron bed frame 2 placed on one side of the first iron bed frame 1; a second limiting support box 5 symmetrically fixed inside the first iron bed frame 1, with a second adjusting slide plate 6 slidably disposed inside the second limiting support box 5, one side of the second adjusting slide plate 6 being fixedly connected to the second iron bed frame 2; a first adjusting support column 23 symmetrically fixed to the bottom of the first iron bed frame 1 and the second iron bed frame 2, with a first support seat 24 slidably disposed on the outer side of the first adjusting support column 23; and the first iron bed frame 1 and the second iron bed frame 2... Fixed support plates 15 are provided at the bottom of the No. 2 iron bed frame 2. Both sides of the fixed support plates 15 are fixedly connected to the No. 1 support base 24. Limiting blocks 22 are symmetrically slidably arranged inside the fixed support plates 15. Through openings 26 are opened on the inner side of the No. 1 support base 24, and the limiting blocks 22 are slidably connected to the through openings 26. Limiting slots 25 are equidistantly opened on the inner side of the No. 1 adjusting support column 23, and the limiting blocks 22 cooperate with the limiting slots 25. The No. 2 adjusting support column 27 is symmetrically fixed to the bottom of the No. 2 iron bed frame 2, and the No. 2 support base 28 is slidably arranged on the outer side of the No. 2 adjusting support column 27.

[0015] It should be noted that, in this embodiment, when adjusting the position between the No. 1 iron bed frame 1 and the No. 2 iron bed frame 2, the length of the iron bed frame is adjusted by pulling down the pull rod 11. The pull rod 11 drives the sliding plate 9 and the locking plate 10 to move downwards. The locking plate 10 moves away from the current limiting slot 7 at the bottom of the No. 2 adjusting slide plate 6. The sliding plate 9 moves downwards and presses the spring 13, thereby adjusting the distance between the No. 1 iron bed frame 1 and the No. 2 iron bed frame 2. When the appropriate limiting slot 7 is reached, the spring 13 will reset and drive the sliding plate 9 to move downwards. The clamping plate 10 is reset upwards and enters the limiting slot 7 at the appropriate position at the bottom of the second adjusting slide plate 6. This allows adjustment of the distance between the first iron bed frame 1 and the second iron bed frame 2, thus adjusting the overall length of the iron bed frame. Then, the tightening bolt 14 is installed to tighten the position of the sliding plate 9, fixing the position of the clamping plate 10 and ensuring the stability of the adjustment position of the second adjusting slide plate 6 within the second limiting support box 5. When adjusting the height of the first iron bed frame 1 and the second iron bed frame 2, the fixing bolt 30 is rotated and removed. The threaded installation between the slot 29 and the threaded groove is achieved by rotating the rotating screw block 17. This rotation drives the worm gear 16, which in turn drives the meshing worm wheel 19. The worm wheel 19 then drives the inner double-acting screw 18, which in turn moves the outer symmetrical slider 20. This movement of the slider 20 moves the sliding bracket 21 and the limiting block 22 on one side, moving the limiting block 22 out of the limiting slot 25. At this point, the first support base 24 and the first adjusting column can be installed. 23. Adjust the height by moving the limit block 22 to the limit slot 25 at the appropriate height. Then, rotate the rotating screw block 17 in the opposite direction. Rotating the screw block 17 will drive the worm gear 16 to rotate in the opposite direction. The worm gear 16 will drive the worm wheel 19 and the double-acting screw 18 to rotate, so that the limit block 22 can be put into the limit slot 25 at the appropriate height. Then, the fixing bolt 30 is threaded into the installation threaded groove 29 at the appropriate height. The No. 2 adjusting column 27 and the No. 2 support seat 28 provide overall support for the No. 2 iron bed frame 2 and the No. 1 iron bed frame 1.

[0016] In one embodiment, such as Figures 1 to 3 As shown, it also includes fixing bolts 30, which are symmetrically and movably arranged inside the second support base 28. Multiple mounting threaded grooves 29 are symmetrically and evenly opened on the outer side of the second adjusting support column 27. The mounting threaded grooves 29 cooperate with the fixing bolts 30. A support frame is fixedly connected to the inner side of the second adjusting support column 27.

[0017] It should be noted that in this embodiment, the fixing bolt 30 and the mounting threaded groove 29 cooperate to fix the adjustment position between the second support seat 28 and the second adjusting column 27, thereby providing overall support for the first iron bed frame 1 and the second iron bed frame 2 and improving the overall stability of the iron bed frame.

The limiting slide rods 12 are fixedly connected to the fixed base box 8. A spring 13 is sleeved on the outside of the limiting slide rod 12. A tightening bolt 14 is installed inside the fixed base box 8.

[0019] It should be noted that in this embodiment, the sliding plate 9 and the clamping plate 10 are pulled by the pull rod 11 to facilitate the adjustment of the position of the second adjusting slide plate 6 in the second limiting support box 5. The sliding plate 9 and the clamping plate 10 are reset by the spring 13, and the clamping plate 10 is fixed between the limiting slot 7 in the appropriate position. The distance between the first iron bed frame 1 and the second iron bed frame 2 is adjusted and fixed. The tightening bolt 14 is set to prevent accidental pulling of the pull rod 11, thereby improving stability.
