Description

Technical Field

[0001] This utility model relates to the field of bed frames, and specifically to a disaster relief folding bed. Background Technology

[0002] Existing disaster relief folding beds typically consist of a bed frame and an Oxford cloth bed surface. The outer frame is a curved frame, and the bed surface is sewn and fixed inside a "bed surface fixing sleeve" within the curved frame. This structure has the following drawbacks:

[0003] Limited load-bearing capacity: The bed surface is only fixed by flexible stitching, relying on the strength of the Oxford cloth itself to bear the weight. There is no rigid support structure, making it difficult to bear large weights. It is prone to deformation and damage, especially in long-term use or complex environments.

[0004] Inconvenient to clean: The bed surface and bed frame are fixed by stitching and cannot be quickly disassembled. Once stains accumulate, the entire bed needs to be cleaned.

[0005] In summary, in order to overcome the shortcomings of existing technologies, it is necessary to design a disaster relief folding bed with a simple structure. Utility Model Content

[0006] This utility model provides a disaster relief folding bed to solve the problems of the prior art.

[0007] The objective of this utility model can be achieved through the following technical solution: A disaster relief folding bed includes a bed frame, a bed sheet, and a support frame. The bed frame includes an outer frame rod, a connecting plate, an X-shaped support plate, and a plastic support plate. The connecting plate is provided in multiple sets at intervals and symmetrically fixed to the inner side of the outer frame rod. The connecting plate has a sliding groove inside. The insertion parts at the four ends of the X-shaped support plate are set in the sliding groove and connected to the connecting plate by fastening bolts. The upper end of the X-shaped support plate forms a groove facing downwards. The plastic support plate is set in the groove. The bed sheet includes an upper bed sheet and a lower bed sheet. The upper bed sheet and the lower bed sheet are connected by a zipper and wrap the outer frame rod, connecting plate, X-shaped support plate, and plastic support plate inside. The support frame is rotatably set at the bottom of the outer frame rod.

[0008] In a further improvement, the outer frame rod includes a bottom frame rod, a middle frame rod, and a head frame rod, and the support frame includes a bottom frame, a middle frame, and a head frame. The bottom frame is rotatably mounted on the rear end of the bottom frame rod via three-point positioning plates. The right end of the bottom frame rod is rotatably connected to the left end of the middle frame via four-point T-shaped positioning plates. The left end of the middle frame rod is rotatably connected to the right end of the middle frame via four-point T-shaped positioning plates. The left end of the head frame rod is rotatably connected to the right end of the middle frame rod and the head frame via four-point positioning plates.

[0009] In a further improvement, the connecting plate and the X-shaped support plate are provided in three sets at intervals.

[0010] As a further improvement, the fastening bolt is a countersunk bolt.

[0011] In a further improvement, the upper and lower bed fabrics are made of Oxford cloth.

[0012] Compared with existing technologies, the beneficial effects of this new disaster relief folding bed are as follows:

[0013] The X-shaped support plate is positioned by the groove of the connecting plate, and the load is distributed by the mechanical properties of the X-shaped structure. The plastic support plate is embedded in the groove of the X-shaped support plate to form a rigid plane, thus constructing a rigid load-bearing system independent of the bed sheet. This avoids tearing or deformation caused by direct stress on the Oxford cloth, significantly improving the load-bearing capacity and allowing it to withstand greater weight. The bed sheet adopts a zipper-removable design. The bed sheet only serves as a protective covering layer and does not participate in mechanical support. It can be removed independently for cleaning, solving the problem that traditional sewn bed sheets cannot be cleaned quickly. Attached Figure Description

[0020] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0021] Example 1

[0022] A disaster relief folding bed includes: a bed frame 1, a bed sheet 2, and a support frame 3. The bed frame 1 includes an outer frame rod 11, a connecting plate 12, an X-shaped support plate 13, and a plastic support plate 14. The connecting plate 12 is provided with multiple sets at intervals and symmetrically fixed to the inner side of the outer frame rod 11. The connecting plate 12 has a sliding groove 121 inside. The four ends of the X-shaped support plate 13 have insertion parts 131 in the sliding groove 121 and are connected to the connecting plate 12 by fastening bolts 132. The upper end of the X-shaped support plate 13 forms a groove 133 facing downward. The plastic support plate 14 is disposed in the groove 133. The bed sheet 2 includes an upper bed sheet 21 and a lower bed sheet 22. The upper bed sheet 21 and the lower bed sheet 22 are connected by a zipper and wrap the outer frame rod 11, the connecting plate 12, the X-shaped support plate 13, and the plastic support plate 14 inside. The support frame 3 is rotatably disposed at the bottom of the outer frame rod 11.

[0023] like Figures 1-4 As shown, the disaster relief folding bed in this embodiment achieves innovation through the cooperation of rigid support components (connecting plate 12, X-shaped support plate 13, and plastic support plate 14) and removable bed fabric 2:

[0024] The connecting plate 12 is symmetrically fixed to the inner side of the outer frame rod 11, and has a sliding groove 121 inside for positioning the insertion part 131 of the X-shaped support plate 13. It is fixed by fastening bolts 132 to form a stable lateral support foundation. The X-shaped support plate 13 is inserted into the sliding groove 121 through the insertion part 131. Utilizing the cross mechanical characteristics of the X-shaped structure, the vertical load is distributed to the outer frame rod 11, improving the overall resistance to deformation. The upper groove 133 is used to embed the plastic support plate 14, further enhancing the planar support rigidity. The plastic support plate 14 is embedded in the groove 133 of the X-shaped support plate 13 to form a continuous rigid plane that directly bears the weight of the human body, preventing the bed sheet 2 from deforming under stress and completely changing the traditional "flexible load-bearing" mode of the bed surface.

[0025] The removable bed sheet 2 consists of an upper bed sheet 21 and a lower bed sheet 22 connected by a zipper, completely enclosing the bed frame 1. The bed sheet serves only as a covering and protective layer and does not participate in mechanical support. It can be quickly removed and washed, solving the problem of inconvenient cleaning of traditional sewn bed sheets.

[0026] As a further preferred embodiment, the outer frame rod 11 includes a bottom frame rod 111, a middle frame rod 112, and a head frame rod 113. The support frame 3 includes a bottom frame 31, a middle frame 32, and a head frame 33. The bottom frame 31 is rotatably mounted on the rear end of the bottom frame rod 111 via a three-point positioning piece 34. The right end of the bottom frame rod 111 is rotatably connected to the left end of the middle frame 32 via a four-point T-shaped positioning piece 35. The left end of the middle frame rod 112 is rotatably connected to the right end of the middle frame 32 via a four-point T-shaped positioning piece 35. The left end of the head frame rod 113 is rotatably connected to the right end of the middle frame rod 112 and the head frame 33 via a four-point positioning piece 36.

[0027] The bottom frame 31 is rotatably connected to the rear end of the bottom frame rod 111 via a three-point positioning piece 34, providing a bottom support point; the right end of the bottom frame rod 111 and the left end of the middle frame rod 112 are rotatably connected to the left and right ends of the middle frame 32 via four-point T-shaped positioning pieces 35, forming a foldable hinged structure in the middle; the left end of the head frame rod 113 is rotatably connected to the right end of the middle frame rod 112 and the head frame 33 via a four-point positioning piece 36, realizing angle adjustment or folding of the head area.

[0028] As a further preferred embodiment, the connecting plate 12 and the X-shaped support plate 13 are provided in three sets at intervals. The three sets of connecting plates 12 and X-shaped support plates 13 are evenly distributed along the length of the bed frame to form a "multi-support lateral support network". Each set of X-shaped support plates 13 is fixed to the sliding groove 121 of the connecting plate 12 through the plug-in part 131, so as to distribute the bed surface load to multiple support points.

[0029] As a further preferred embodiment, the fastening bolt 132 is a countersunk bolt. The head of the countersunk bolt is embedded in the countersunk hole of the connecting plate 12 or the X-shaped support plate 13, so that the bolt head is flush with the support surface, avoiding the exposed head of the traditional bolt, and preventing the bed sheet 2 from being worn by the bolt head or accidentally scratched by the user.

[0030] As a further preferred embodiment, the upper bed fabric 21 and the lower bed fabric 22 are made of Oxford cloth. Oxford cloth has the characteristics of high strength, wear resistance, and water resistance, making it suitable for harsh environments in disaster relief scenarios (such as outdoor mud and dampness) and extending the service life of the bed.

[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
