Detailed implementation manners

[0032] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] A conveniently movable iron frame bed, as Figure 1 、 Figure 2 shown, includes a bed body 1 and a plurality of support legs 2. The plurality of support legs 2 are located on the lower surface of the bed body 1. A sliding hole 3 is formed in the bottom surface of the support legs 2. A roller assembly 4 is installed in the sliding hole 3. An elevating assembly 5 for driving the roller assembly 4 to lift is installed on the support legs 2.

[0034] As Figure 3 shown, it is worth mentioning that the roller assembly 4 includes: universal wheels 401 with a braking assembly, and a lifting rod 402. The universal wheels 401 are fixed to the end of the lifting rod 402 by welding. The lifting rod 402 is slidably installed in the sliding hole 3. The end of the lifting rod 402 away from the universal wheels 401 is threadedly connected to the threaded rod 501.

[0035] As Figure 4 shown (refer to Figure 5 ), the elevating assembly 5 includes: a support plate 502 installed in the sliding hole 3. A threaded rod 501 is actively installed on the support plate 502. The roller assembly 4 is threadedly connected to the threaded rod 501. One end of the threaded rod 501 protrudes from the support plate 502. A first bevel gear 503 is fixedly installed at the end of the threaded rod 501 protruding from the support plate 502. A second bevel gear 504 cooperating with the first bevel gear 503 is provided beside the first bevel gear 503. One end of the second bevel gear 504 is fixed with a rotating rod 505. The rotating rod 505 extends to the outer wall of the support leg 2 and is rotatably connected to the support leg 2. A turntable 506 is fixed at the end of the rotating rod 505 extending to the outer wall of the support leg 2.

[0036] As Figure 3 shown (refer to Figure 6), in order to ensure that the roller assemblies 4 in the four support legs 2 are at the same horizontal plane after moving downward, in some embodiments, chambers 6 and round holes 7 are provided around the outer wall of the lifting rod 402. The round holes 7 penetrate through the outer wall of the lifting rod 402 and communicate with the chambers 6. A positioning pin 8 is slidably installed in the chambers 6 and round holes 7. One end of the positioning pin 8 is arranged in a semi-spherical shape. A spring 9 is provided between the positioning pin 8 and the inner side wall of the chamber 6. A positioning hole 10 with the same size and shape as the positioning pin 8 is provided on the inner side wall of the sliding hole 3. During the downward movement of the lifting rod 402, when the positioning hole 10 and the positioning pin 8 move to be coaxial, under the action of the spring 9, the positioning pin 8 is ejected from the chambers 6 and round holes 7 into the positioning hole 10.

[0037] It is worth mentioning that, in order to conveniently see whether the roller assembly 4 has descended in place, an observation window 11 is provided on the side wall of the support leg 2 and above the positioning hole 10 on the lifting rod 402. Scale lines 12 are provided on the side wall of the support leg 2 beside the observation window 11 and on the lifting rod 402.

[0038] As Figure 4 shown, in some embodiments, in order to reinforce the support of the four support legs 2 and improve the stability of the support legs 2, a support cylinder 13 for reinforcing the support legs 2 is threadedly connected to the outer wall of the support legs 2. In order to facilitate the rotation of the support cylinder 13 on the support legs 2, a plurality of rotating rods 14 for rotating the support legs 2 are provided on the outer wall of the support cylinder 13. In order to prevent the iron frame bed from sliding during use, anti-slip pads 15 are provided on the surfaces of the support cylinder 13 and the support legs 2 in contact with the bottom surface.

[0039] The working process and beneficial effects of the present utility model are as follows:

[0040] When it is necessary to move the iron frame bed, by rotating the turntable 506, the turntable 506 drives the rotating rod 505 and the second bevel gear 504 to rotate, and drives the first bevel gear 503 and the threaded rod 501 engaged with the second bevel gear 504 to rotate on the support plate 502, so that the lifting rod 402 descends in the sliding hole 3, and the universal wheels 401 are extended from the support legs 2, thereby facilitating the movement of the iron frame bed. The iron frame bed is moved to a suitable place through the roller assembly 4, solving the problem in the prior art that the iron frame bed is bulky and inconvenient to carry and move.

[0041] When it is not necessary to move the iron frame bed, by rotating the rotating rod 14 to rotate the support cylinder 13, the support cylinder 13 is rotated off the support legs 2, reinforcing the support of the four support legs 2 and improving the stability of the support legs 2. The provided anti-slip pads 15 increase the friction between the support legs 2 and the support cylinder 13 and the ground, avoiding the iron frame bed from sliding during use.

[0042] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
