Description

Technical Field

[0001] The utility model relates to the technical field of household mattress brackets, in particular to a folding mattress bracket. Background Art

[0002] For small-sized household beds, a storage bed with a storage cavity is the best choice. In this type of storage bed, the storage cavity is located under the bed board. When you need to take out or put items in the storage cavity, you need to flip the bed board open or take it down.

[0003] The solution recorded in the utility model patent with the authorization announcement number CN2370753Y: it includes a four-link stabilizer frame and a gas spring, wherein the four-link stabilizer frame includes horizontally arranged side panels, long connecting rods, short connecting rods and a top plate fixed to the bottom surface of the bed board, and the four rods are hinged in sequence to form an unequal quadrilateral frame, and one end of the gas spring is hinged to the bottom surface of the top plate, and the other end is hinged to the midpoint of the long connecting rod. When turned on, the gas spring slowly extends outward under the action of a sudden external force, and pushes the long connecting rod to drive the bed board to flip upward. However, in this solution, the gas spring is connected to a four-link stabilizer frame. In actual application, the four-link structure is easy to deform, and the gas spring will also move, so that the mattress cannot be kept still when it is lifted.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Combination Figure 1 , Figure 2 and Figure 3 The utility model is described in detail. The mattress folding bracket of the utility model comprises a fixed rod 1, a first rod 2, a second rod 3 and a third rod 4.

[0026] The fixed rod 1 is fixed to the bed body; the third rod 4 is fixed to the bed board.

[0027] One end of the fixed rod 1 is hinged to one end of the first rod 2, and the proximal end of the other end is hinged to one end of the second rod 3; the other end of the first rod 2 is hinged to the third rod 4, and the other end of the second rod 3 is hinged to the third rod 4 at the middle section of the third rod 4;

[0028] The fixing rod 1 is provided with a first connecting through hole 15 on the outer side of the hinged position with the second rod 3, and the third rod 4 is provided with a second connecting through hole 43 at the proximal end position. A gas spring is provided between the first connecting through hole 15 and the second connecting through hole 33, which is not shown in the figure.

[0029] The second rod 3 is longer than the first rod 2, which can effectively increase the lifting height.

[0030] The extension or retraction of the gas spring drives the second rod 3 to rotate in the vertical plane, thereby lifting the bed board, so that the space under the bed board can be easily utilized. One end of the gas spring cylinder is hinged to the fixed rod 1 at the position of the first connecting hole 15, and one end of the telescopic rod is hinged to the third rod 4 at the position of the second connecting hole 33.

[0031] Furthermore, the second rod 3 includes a first sub-rod 31 hinged to the third rod 4 and a second sub-rod 32 hinged to the fixed rod 1; the angle between the first sub-rod 31 and the second sub-rod 32 is an obtuse angle, and the second sub-rod 32 is longer than the first sub-rod 31. The specific obtuse angle is 160-179°. The setting of the obtuse angle enables the second rod 3 to support the third rod 4 along the direction of the first sub-rod 31. The angle between the first sub-rod 31 and the third rod 4 is greater than the angle between the second sub-rod 32 and the third rod 4, so that the third rod 4 can be supported more strongly, thereby ensuring the stability of the mattress folding bracket when it is in the lifted state.

[0032] Furthermore, the fixed rod 1 includes a first bending plate 11, a second bending plate 12 and a third bending plate 13 arranged along the length direction of the fixed rod 1; the second bending plate 12 is perpendicular to the first bending plate 11 and the third bending plate 13; the first rod 2 and the second rod 3 are hinged to the fixed rod 1 at the first bending plate 11. In the folded state, the first rod 2, the second rod 3 and the third rod 4 and the gas spring are folded above the second bending plate 12 and to the side of the second bending plate 13.

[0033] Furthermore, the fixing rod 1 is provided with a hollow portion 14, which can reduce the weight of the fixing rod 1 and has a weight-reducing effect.

[0034] Further, the hinge point between the third rod 4 and the second rod 3 is located between one third and two thirds of the length of the third rod 4. In the present invention, the hinge point between the third rod 4 and the second rod 3 is located at the midpoint of the third rod 4.

[0035] Furthermore, the third rod 4 includes a fourth bending plate 41 and a fifth bending plate 42, that is, the cross section of the third rod 4 is L-shaped. The first rod 2 and the second rod 3 are hinged to the fifth bending plate 42 and the second rod 3; the fourth bending plate 41 is fixed to the bed board.

[0036] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
