[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-Figure 3 The utility model provides a technical solution: a foldable double-layer folding bed, comprising a front bracket 1, a ladder 2 is fixed to the right side of the front bracket 1, a rear bracket 3 is arranged on the rear side of the front bracket 1, a side bracket 4 and an intermediate bracket 5 are arranged between the rear bracket 3 and the front bracket 1, a bed frame 6 is connected between the front bracket 1, the rear bracket 3, the side bracket 4 and the intermediate bracket 5, a mattress 7 is fixed to the upper end surface of the bed frame 6, and pulleys 9 are installed on the lower sides of the front bracket 1 and the rear bracket 3.

[0018] Two groups of footrests 401 are also fixed to the side brackets 4 symmetrically in front and back, and a crossbar 402 is fixed between the left and right side brackets 4, and the crossbar 402 is in contact with the bed frame 6 to achieve a supporting effect. Through the action of the footrests 401, the entire folding bed can be easily unfolded, and the support of the crossbar 402 on the bed frame 6 can ensure the stability of the folding bed after unfolding; a support platform 501 is also fixed to the middle bracket 5, and pulleys 9 are symmetrically installed in front and back of the lower end of the support platform 501, and the support platform 501 is in contact with the bed frame 6 to achieve a supporting effect. Through the above structure, To ensure the stability of the bunk frame 6 after it is unfolded; the bunk frame 6 is provided with two groups, upper and lower, between the front support 1 and the rear support 3, and each group is composed of four bunk frames 6, and a guardrail 8 is fixed on the second row of bunk frames 6 on the upper side. Through the function of the guardrail 8, a protective function can be achieved to ensure the safety of the upper personnel; the second bunk frame 6 is rotatably connected to the front support 1, the rear support 3 and the side support 4, and the second bunk frame 6 is also rotatably connected to the support platform 501. The rotatable connection of the second bunk frame 6 is the basic guarantee to ensure that the folding bed can be normally unfolded and stored;

[0019] When using the foldable bunk bed, Figure 3 As shown, at this time, the entire double-layer folding bed is in the storage state. With the function of the pulley 9, the entire folding bed can be easily moved, which is convenient for later transportation and storage. In actual use, when the entire folding bed needs to be unfolded, as shown in FIG. Figure 1-Figure 3 As shown, it is only necessary to step on the pedal rod 401, so that the side bracket 4 is forced to move downward, and the rotation between the second bed frame 6 and the front bracket 1, the rear bracket 3, the side bracket 4 and the support platform 501 can make the entire folding bed unfold until the second bed frame 6 is in a horizontal state. At this time, the second bed frame 6 is in contact with the support platform 501 and the cross bar 402 to achieve a supporting effect, thereby ensuring the stability of the unfolded folding bed;

[0020] The side brackets 4 are symmetrically distributed in two groups about the center line of the middle bracket 5, and the height of the side brackets 4 is equal to the total height of the middle bracket 5 after the pulley 9 is installed. By limiting the height of the side brackets 4, it can be ensured that after the folding bed is unfolded, the side brackets 4 are just in contact with the ground to achieve support, thereby ensuring the stability of the folding bed; the lower end surface of the side bracket 4 is also nested and installed with a protective pad 403, and the protective pad 403 is made of rubber material. Through the above structure, when the folding bed is unfolded, the side brackets 4 can be prevented from directly contacting and bumping with the ground to cause damage to the ground or the side brackets 4, thereby ensuring safety in use;

[0021] When the folding bed is unfolded, Figure 1 and Figure 2As shown, the protective function of the protective pad 403 can prevent the side bracket 4 from colliding with the ground and causing damage, thereby ensuring the safe use of the folding bed. After the folding bed is unfolded, the protective pad 403 contacts the ground and cooperates with the side bracket 4 to achieve the supporting function of the folding bed and ensure the stability of the folding bed. This is the working principle of the retractable double-layer folding bed.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
