Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses dormitory bed of adjustable back. Referring to fig. 1, the dormitory bed includes a bed body 1, a ladder 2 welded to one side of the bed body 1, a computer table 3 installed below the bed body 1, and a wardrobe 4 installed at one side of the computer table 3.

Referring to fig. 1, the bed body 1 includes a bed plate 11, two long guardrails 12 and two wide guardrails surrounding the bed plate 11. Wherein, the long guard rail 12 on one side is provided with an opening at the position of the ladder 2. One side of the bed plate 11 far away from the ladder stand 2 is provided with a hinge groove 111, and one side wall of the hinge groove 111 near the ladder stand 2 is hinged with a rotating plate 5. The rotating plate 5 is rotatably connected with the bed plate 11 through a pin shaft, and the axis of the pin shaft is the same as the width direction of the bed plate 11. When the rotating plate 5 is in a horizontal state, the upper surface of the rotating plate is flush with the upper surface of the bed plate 11. One side of the hinge groove 111 away from the ladder stand 2 is hinged with a support rod 6, and the rotation axis of the support rod 6 is parallel to the rotation axis of the rotating plate 5.

Referring to fig. 1 and 2, one end of the support rod 6 is hinged to the groove wall of the hinge groove 111, and the other end is hinged to the support block 61. The bottom of the rotating plate 5 is provided with a sliding groove 51 along the direction perpendicular to the rotating axis, and the sliding groove 51 is arranged on the central line of the rotating plate 5. The sliding groove 51 has a closed structure at both ends. The support block 61 slides in the slide groove 51. The rotating plate 5 is provided with an adjusting component 7. The angle between the rotating plate 5 and the bed plate 11 is adjusted through the adjusting component 7, so that a comfortable leaning angle is provided for a human body.

Referring to fig. 2 and 3, the adjustment assembly 7 includes a screw 71 and a driver for driving the screw 71 to rotate. The drive employs a rotating rod 72. One end of the screw rod 71 is rotatably mounted on the wall of the sliding groove 51 near the ladder 2 through a bearing, and the other end of the screw rod passes through the wall of the sliding groove 51 and extends to the outside of the rotating plate 5 to be connected with the rotating rod 72. A gap 131 is formed on the wide guardrail 13 at one side far away from the ladder 2, and when the screw 71 and the rotating rod 72 extending to the outside of the rotating plate 5 rotate around the axis of the rotating plate 5, no interference is generated by the arrangement of the gap 131.

Referring to fig. 3, a through hole 711 is formed in an end portion of the screw 71 extending out of the rotating plate 5, the rotating rod 72 is slidably disposed through the through hole 711, and the rotating rod 72 is perpendicular to the screw 71. The outer wall of one end of the rotating rod 72 is protruded with a limiting ring 722, and the other end is perpendicularly welded with a holding rod 721. The rotation rod 72 is not separated from the screw 71 due to the arrangement of the limiting ring 722 and the holding rod 721. The rotating rod 72 penetrates through the end of the screw rod 71 in a sliding mode, so that the rotating rod 72 cannot extend to the upper surface of the rotating plate 5, and the situation that the rotating rod 72 interferes with a human body when the human body leans against the rotating plate 5 is reduced. In other embodiments, the driving member can also use a driving motor with a forward and reverse rotation function to drive the screw rod 71 to rotate.

Referring to fig. 3, in order to make the grip 721 always face away from the rotating plate 5, it is convenient for a human hand to rotate the grip 721. The outer wall of the rotating rod 72 is provided with a limiting strip 723 in a protruding manner along the length direction, and the inner wall of the through hole 711 is provided with a limiting groove 712 for slidably clamping the limiting strip 723.

Referring to fig. 1 and 4, the long guard rail 12 further includes a cross bar 121 having the same length direction as the bed plate 11. The cross rod 121 is a cylindrical structure, and the outer wall of the cross rod 121 at the side where the hinge groove 111 is located is rotatably sleeved with the support sleeve 8. An auxiliary plate 81 is welded and fixed on the support sleeve 8. When the auxiliary plate 81 is in a horizontal state, a part of the projection of the auxiliary plate 81 is located within the projection of the rotating plate 5. The supporting sleeve 8 is provided with a locking piece.

Referring to fig. 1 and 4, the locking member employs a locking bolt 9. The locking bolt 9 is connected to one side of the support sleeve 8 far away from the auxiliary plate 81 in a threaded manner, and the locking bolt 9 penetrates through the support sleeve 8. The cross bar 121 is provided with a guide groove 122 along the length direction for the locking bolt 9 to abut against. After the rotating plate 5 is rotated and turned up, the end part of the locking bolt 9 slides in the guide groove 122, the auxiliary plate 81 is kept in a horizontal state, the side wall of the auxiliary plate 81 is abutted against the lower end surface of the rotating plate 5 through the sliding support sleeve 8, then the locking bolt 9 is abutted against the groove wall of the guide groove 122, and the support sleeve 8 is fixed. When the rotating plate 5 is horizontal, the locking bolt 9 is loosened to separate the end part from the guide groove 122, and the support sleeve 8 is rotated to make the auxiliary plate 81 in a vertical downward state so as to reduce the interference of the auxiliary plate 81 to the moving space of the human body.

The implementation principle of the dormitory bed with the adjustable backrest in the embodiment of the application is as follows:

when the rotating plate 5 needs to be turned up for a human body to lean against, the holding rod 721 is rotated to further drive the screw rod 71 to rotate, the screw rod 71 drives the supporting block 61 to move along the axis of the screw rod 71, so that the supporting rod 6 is driven to rotate, the supporting rod 6 and the rotating plate 5 form a proper included angle, and the supporting plate is supported; the position of the support sleeve 8 is then adjusted by the locking bolt 9 so that the auxiliary plate 81 further supports the rotating plate 5, improving stability. Therefore, the leaning comfort of the human body can be improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
