Description

Technical Field

[0001] This utility model belongs to the field of equipment used in outdoor environments, and relates to camp beds, and in particular to a camp bed with an adjustable backrest. Background Technology

[0002] Camp beds are used by troops during marches. They are foldable beds made of a wooden or metal frame with canvas attached. They are mainly used for marching or field work. They are small in size when folded and bagged, making them easy to carry.

[0003] A folding cot, as disclosed in CN204599915U, includes a bed frame and multiple support legs. Each support leg has a T-shaped structure consisting of a horizontal sleeve and a vertical support leg. The multiple support legs are respectively mounted on the bed frame through the horizontal sleeve and have both a fixed and a movable state. In the movable state, the vertical support legs are folded in a plane with the bed frame. This folding cot has the advantages of simple structure, small size, light weight, high strength, and long service life, and is particularly suitable for harsh environments such as the field, thus possessing significant promotional value.

[0004] The aforementioned cot is the most common type of cot. During marches, the cot can be folded and stored for easy transport. However, when in use, because the bed board of the cot is fixed to the bed frame by welding or screws, when there are wounded soldiers with fractures who cannot lie upright due to their physical condition, the angle of the bed board cannot be adjusted according to the user's needs, resulting in inconvenience. Utility Model Content

[0005] This utility model provides an adjustable backrest cot, which can adjust the angle of the bed board so that the cot can be adjusted according to the user's needs.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an adjustable backrest cot, including a bed frame and a number of bed boards set on the bed frame, with adjacent bed boards rotatably connected, each bed board including a rotating plate and a fixed plate, the fixed plate being fixedly connected to the bed frame, the rotating plate being rotatably connected to the bed frame, and an angle between the rotating plate and the bed frame, a sliding rod being slidably connected to the bed frame, and a support rod being hinged between the sliding rod and the rotating plate, wherein when the sliding rod slides, the support rod rotates and the angle changes.

[0007] A further preferred embodiment of this utility model is as follows: two sliding grooves are provided on the bed frame, and the sliding rod passes through the two sliding grooves and slides within the sliding grooves.

[0008] A further preferred embodiment of this utility model is as follows: the support rod abuts against the outer side of the bed frame, and when the rotating plate is in contact with the bed frame, the inner side wall of the support rod is in contact with the outer side wall of the bed frame.

[0009] A further preferred technical solution of this utility model is as follows: each of the slide grooves is slidably connected with a U-shaped plug, and the two ends of the slide rod are respectively located in two U-shaped plugs. Several slots are opened on the top surface of the slide groove to facilitate the insertion of the U-shaped plugs. When the U-shaped plugs are inserted into the slots, the slide rod is fixed.

[0010] A further preferred embodiment of this invention is that there is a gap between the U-shaped plug and the slide bar. When the U-shaped plug separates from the slot, the gap increases and the slide bar slides.

[0011] A further preferred technical solution of this utility model is as follows: a pull rod extending out of the slide groove is integrally formed on the bottom surface of the U-shaped plug-in, and a spring is sleeved on the pull rod between the pull rod and the bed frame. When the U-shaped plug-in is separated from the slot, the spring deforms.

[0012] A further preferred technical solution of this utility model is as follows: the pull rod is integrally formed with a slot, and the bed frame is provided with a slot to facilitate the insertion of the card block. When the card block is inserted into the slot, the U-shaped plug-in is separated from the slot and fixed.

[0013] A further preferred embodiment of this utility model is that the slide bar has an annular groove to facilitate the insertion of a U-shaped plug.

[0014] Compared with the prior art, this utility model includes a bed frame and several bed boards, with adjacent bed boards rotatably connected. Each bed board includes a rotating plate and a fixed plate. The fixed plate is fixedly connected to the bed frame, and the rotating plate is rotatably connected to the bed frame. There is an angle between the rotating plate and the bed frame. A sliding rod is slidably connected to the bed frame, and a support rod is hinged between the sliding rod and the rotating plate. When the sliding rod slides, the support rod rotates and the angle changes. Therefore, when it is necessary to adjust the angle of the rotating plate, the sliding rod is slid. At this time, as the sliding rod slides, the support rod rotates and pushes the rotating plate to rotate until the appropriate angle is reached. This design allows the angle of the bed board of the cot to be adjusted according to the needs of the injured person, thus making it suitable for use by patients with fractures and broadening the application range of the cot.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] Figure 1 and Figure 2 As shown, an adjustable backrest cot includes a bed frame 1 and several bed boards mounted on the bed frame 1. The bed boards are arranged in three pieces, with adjacent bed boards rotatably connected. Each bed board includes a rotating plate 3 and a fixed plate 2. Two fixed plates 2 are fixedly connected to the bed frame 1, and one rotating plate 3 is rotatably connected to the bed frame 1.

[0027] Figure 1 and Figure 2 As shown, during marches, the size of the cot can be reduced by folding the cot frame 1 and the cot board, making it easier to carry. When in use, the cot frame 1 and the cot board can be unfolded for easy use by soldiers.

[0028] Figure 1 and Figure 2 As shown, there is an angle between the rotating plate 3 and the bed frame 1. A sliding rod 5 is slidably connected to the bed frame 1. Two sliding grooves 6 are opened on the bed frame 1. The sliding rod 5 passes through the two sliding grooves 6 and slides within the sliding grooves 6. A support rod 4 is hinged between the sliding rod 5 and the rotating plate 3. When the sliding rod 5 slides, the support rod 4 rotates and the angle changes.

[0029] Figure 1 and Figure 2 As shown, when a wounded soldier with a fracture lies on the cot, the sliding rod 5 slides within the groove 6. As the sliding rod 5 slides, the support rod 4 rotates accordingly. At this time, the rotating plate 3 rotates upward under the push of the support rod 4, thereby increasing the included angle until it reaches a comfortable angle for the wounded soldier. This design allows the angle of the cot's bed board to be adjusted according to the actual situation and the user's needs, thus broadening the applicability of the cot and improving its practicality and comfort.

[0030] Figure 1 and Figure 2 As shown, the support rod 4 abuts against the outer side of the bed frame 1. When the rotating plate 3 is in contact with the bed frame 1, the inner side wall of the support rod 4 is in contact with the outer side wall of the bed frame 1.

[0031] Figure 1 and Figure 2 As shown, when folding the cot, the sliding rod 5 is reversed, causing the support rod 4 to rotate in the opposite direction and the rotating plate 3 to be lowered until the rotating plate 3 is in contact with the cot frame 1. At this time, the support rod 4 is located on both sides of the cot frame 1 and is in contact with it. This design allows the support rod 4 to be folded, thereby avoiding affecting the carrying of the cot.

[0032] Figures 3-7 As shown, each slide groove 6 is slidably connected with a U-shaped plug 8. The two ends of the slide rod 5 are respectively located in two U-shaped plugs 8. Several slots 13 are opened on the top surface of the slide groove 6 to facilitate the insertion of the U-shaped plugs 8. When the U-shaped plug 8 is inserted into the slot 13, the slide rod 5 is fixed.

[0033] Figures 3-7 As shown, after the slide bar 5 adjusts the angle of the rotating plate 3, the U-shaped plug 8 is inserted into the slot 13. At this time, the range of motion of the slide bar 5 is restricted within the U-shaped plug 8, thereby fixing the position of the slide bar 5 and preventing the rotating plate 3 from rotating and affecting the use of the cot. This design serves to fix the slide bar 5 after it slides.

[0034] Figures 3-7As shown, there is a gap between the U-shaped plug and the slide bar 5. When the U-shaped plug 8 separates from the slot 13, the gap increases and the slide bar 5 slides. Therefore, when the U-shaped plug 8 separates from the slot 13, the gap between the U-shaped plug 8 and the slide bar 5 increases, which facilitates the smooth sliding of the slide bar 5 and prevents the U-shaped slot 13 from affecting the sliding of the slide bar 5.

[0035] Figures 3-7 As shown, a pull rod 9 extending out of the slide groove 6 is integrally formed on the bottom surface of the U-shaped plug 8. A through groove 7 is provided on the frame to facilitate the sliding of the pull rod 9. The through groove 7 is a strip-shaped groove. When the slide rod 5 slides, the pull rod 9 can slide in the through groove 7. A spring 10 is sleeved on the pull rod 9 between the pull rod 9 and the bed frame 1. When the U-shaped plug 8 is separated from the slot 13, the spring 10 deforms.

[0036] Figures 3-7 As shown, by setting the pull rod 9, the position of the U-shaped plug 8 can be easily controlled. When it is necessary to slide the slide bar 5, pulling the pull rod 9 will separate the U-shaped plug 8 from the slot 13. At this time, the spring 10 will deform due to compression, and the slide bar 5 can be slid smoothly until the appropriate position is reached. Then, the force applied to the pull rod 9 will be released. At this time, the deformed spring 10 will push the U-shaped plug 8 into the slot 13, thereby fixing the position of the slide bar 5. At this time, the spring 10 plays the role of driving the U-shaped plug 8 to reset and thus fixing the slide bar 5.

[0037] Figures 3-7 As shown, the slide bar 5 has an annular groove 15 to facilitate the insertion of the U-shaped plug 8. When the U-shaped plug 8 is inserted into the slot 13, the U-shaped plug 8 is inserted into the annular groove 15, thereby preventing the slide bar 5 from sliding back and forth in the fixed state and affecting the fixation. In this design, the cooperation between the U-shaped plug 8 and the annular groove 15 further restricts the range of motion of the slide bar 5.

[0038] Figures 3-7 As shown, the pull rod 9 has an integrally formed slot 12, and the bed frame 1 has a slot 12 for easy insertion of the locking block 11. The slot 12 is a strip-shaped groove, which allows the locking block 11 to slide together with the sliding rod 5 when it is located in the slot 12. When the locking block 11 is inserted into the slot 12, the U-shaped plug 8 is separated from the slot 13 and fixed.

[0039] Figures 3-7 As shown, when the lever 9 is pulled outward, the locking block 11 engages with the slot 12, thus fixing the lever 9 and the U-shaped plug 8. At this time, the U-shaped plug 8 separates from the slot 13, making it easier to slide the slide rod 5. When it slides inward, the lever 9 is also pushed, causing the locking block 11 to separate from the slot 12. The deformed spring 10 can then drive the U-shaped plug 8 to insert into the slot 13, thereby fixing the slide rod 5. In this design, the cooperation between the locking block 11 and the slot 12 can fix the lever 9, thus avoiding the situation of continuously pulling the lever 9, and improving the ease of operation.

[0040] The above describes an adjustable-back cot provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments are merely for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
