Description

Technical Field

[0001] The invention relates to the technical field of dormitory beds, in particular to a fall-proof dormitory bed for students. Background Art

[0002] A student dormitory can usually accommodate several students in one room, but the space in the dormitory room is limited. Each student needs to place daily necessities. Therefore, in order to improve living conditions, the previous double bunk beds are usually changed to the current upper bunk bed with a storage cabinet under the bed. Dormitory beds are widely used in dormitories. However, dormitory beds are usually single beds, and students can easily fall off the bed when turning over in their sleep. In the past, the news kept reporting about students falling off dormitory beds, making us more and more aware of the safety of dormitory beds.

[0003] In order to prevent students from falling off the bed, the existing dormitory beds for students usually have a climbing body arranged at one end of the side of the bed board, so a guardrail is usually welded in the middle of the side of the bed board away from the wall, which has a certain blocking effect. However, since many students are young and petite, they turn over frequently when sleeping, and it is very easy for them to fall off from the gap between the guardrail and the head of the bed, which poses a great safety hazard; CN 112603096 A discloses a fall-proof dormitory bed for students. The device has a ladder at the tail of the bed board, which increases the length of the dormitory bed and occupies a larger dormitory space than previous dormitory beds, making it difficult to accommodate the specified number of dormitory beds. The device arranges a bed guard on the bed board and a placement mechanism on the bed guard, so that the overall height of the dormitory bed is relatively high. It is difficult for normal school dormitories to accommodate the height of this type of dormitory bed, which limits the use of this type of dormitory bed. In order to prevent falling, the dormitory bed is provided with bed guards all around the bed board, which restricts students' limb activities and affects their sleep quality. Existing dormitory beds only achieve the purpose of sleeping and have relatively single functions. Therefore, we propose an fall-proof dormitory bed for students. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-8 The present invention provides a technical solution: a fall-proof dormitory bed for students, comprising a bed board 1 and a support column 2, both ends of the bed board 1 are provided with a bed head 12, both ends of the corresponding two side walls of the bed board 1 are fixedly connected with the support column 2, the side walls of the two support columns 2 at one end of the bottom of the bed board 1 are fixedly connected with a clothing cabinet 5, and the side of the clothing cabinet 5 is fixedly connected with a computer desk 4.

[0030] It should be noted that the clothing cabinet 5 and the computer desk 4 are arranged at the bottom of the bed board 1. Considering that students need to read books and use computers during school, it is convenient for students to use them at any time, so that students can have sufficient private study space, and the clothing cabinet 5 is convenient for students to store their clothes.

[0031] The side of the computer desk 4 away from the clothing cabinet 5 is fixedly connected to the side walls of the two support columns 2 at both ends of the bottom of the bed board 1, and the tops of the four support columns 2 are provided with height-adjustable support top plates 8, and the bottom of the support top plates 8 is provided with an expandable and retractable desktop panel 13, one end of the side wall of the bed board 1 is fixedly connected to a climbing ladder 3, and the end of the side wall of the bed board 1 away from the climbing ladder 3 is provided with a storage slot 7, and the top of the bed board 1 is provided with a retractable anti-fall guardrail 6 at one end of the storage slot 7.

[0032] It should be noted that when the present invention is used, when the dormitory bed is installed in the student dormitory, the height position of the supporting top plate 8 is adjusted according to the spatial height of the student dormitory. During the adjustment, the installer loosens the positioning bolts 11, and then lifts the supporting top plate 8 to a certain height so that the dormitory bed can be placed in the dormitory. After adjusting the height of the supporting top plate 8, the positioning bolts 11 are tightened to fix the height position of the supporting top plate 8. The student climbs onto the bed board 1 through the climbing ladder 3. When the student wants to read a book or place a water cup, the servo motor 21 can be controlled by the control panel provided in the device to rotate the bidirectional screw 16. The two sliding blocks 17 are connected to the threads at both ends of the bidirectional screw 16 to move the two sliding blocks 17 away from each other. When the two sliding blocks 17 move away from each other at the same time, the sliding block 17 pushes the connecting block 20 to move downward. When the connecting block 20 reaches the appropriate height position, the servo motor 21 can be controlled to rotate. The servo motor 21 stops working and the control lighting 14 is turned on. At this time, the student can place books or water cups on the desktop panel 13. When the student needs to place items for easy use, the adjusting screw 34 can be loosened, and then the lifting frame 31 can be pulled up to unfold the connecting cloth 32. After pulling the lifting frame 31 to the top of the vertical plate 30, the adjusting screw 34 is tightened to form a storage slot 7 as a whole, which is convenient for placing items and avoids the accumulation of debris on the bed. When the student does not want to use the anti-fall guardrail 6 for enclosure, the pull plate 26 can be pushed to the position of the storage slot 7, so that multiple blocking plates 25 are stacked together, so that the space on the bed is larger, which is convenient for arm stretching. When the student is sleeping, the pull plate 26 can be pulled to unfold the multiple blocking plates 25 to form a fence, so that the end close to the outside position is completely enclosed, thereby preventing the student from falling off the bed.

[0033] The bottom of the support top plate 8 is symmetrically fixedly connected with a fixing plate 15, and a bidirectional screw 16 is rotatably connected between the two fixing plates 15 through a bearing. A servo motor 21 is fixedly installed on the side wall of the fixing plate 15 at one end of the bottom of the bed board 1, and the output shaft end of the servo motor 21 passes through the fixing plate 15 and is fixedly connected to the bidirectional screw 16. The two ends of the bidirectional screw 16 are symmetrically threadedly connected with sliding blocks 17. A U-shaped groove is provided at the bottom of the sliding block 17, and an adjusting rod 18 is rotatably connected in the U-shaped groove. Connecting blocks 20 are symmetrically fixedly connected at both ends of the top of the desktop panel 13, and the ends of the two adjusting rods 18 are rotatably connected to the two connecting blocks 20 respectively. The bottom of the support top plate 8 is located outside the desktop panel 13 and a lighting lamp 14 is fixedly installed.

[0034] It should be noted that the desktop panel 13 can be lifted to the bottom of the supporting top plate 8 when not in use, so that the space above the bed board 1 is larger, which is convenient for students' activities. When students read books or place water cups, the desktop panel 13 can be lowered to a position convenient for students to use. A control panel is provided at the head of the student's bed 12. When the height of the desktop panel 13 is adjusted, the servo motor 21 is controlled by the control panel to rotate the bidirectional screw 16. The two sliding blocks 17 are threadedly connected to the two ends of the bidirectional screw 16 to make the two sliding blocks 17 approach or move away at the same time. When the two sliding blocks 17 move away from each other at the same time, the adjusting rod 18 is gradually in a vertical state, and the two adjusting rods 18 push the desktop panel 13 downward, so that the desktop panel 13 is placed in a position convenient for students to use.

[0035] The storage slot 7 includes a bottom plate 29, a vertical plate 30, a lifting frame 31 and a connecting cloth 32. The bottom plate 29 is fixedly connected to one end of the side wall of the bed board 1 away from the climbing ladder 3, and threaded holes 33 are symmetrically fixedly connected at both ends of the top of the bottom plate 29. A lifting frame 31 is provided on the top of the bottom plate 29, and vertical connecting grooves are symmetrically opened at both ends of the top of the lifting frame 31. The vertical plate 30 is slidably connected in the connecting groove, and a connecting cloth 32 is fixedly connected between the top of the bottom plate 29 and the lifting frame 31.

[0036] It should be noted that, by providing a storage slot 7, it is convenient to store sundries and avoid the situation where sundries are piled up on the bed and affect students' rest. By providing a height-adjustable lifting frame 31, the height of the storage slot 7 can be adjusted as needed, so that the higher the height of the storage slot 7, the more sundries it can accommodate. When there are fewer sundries, the height of the storage slot 7 can be lowered, thereby making it easier to take items.

[0037] The side walls of the vertical plate 30 are equidistantly provided with threaded holes 33 , and the corresponding side walls of the lifting frame 31 are provided with adjusting screws 34 , and the ends of the adjusting screws 34 are threadedly connected in the threaded holes 33 , and the lifting frame 31 and the vertical plate 30 are fixedly connected by the adjusting screws 34 .

[0038] It should be noted that when students need to place handy items, they can loosen the adjusting screw 34 and then pull up the lifting frame 31 to unfold the connecting cloth 32. After pulling the lifting frame 31 to the top of the vertical board 30, they can tighten the adjusting screw 34 to form a storage slot 7 as a whole, which is convenient for placing items and avoids the accumulation of debris on the bed.

[0039] The top of the bed board 1 is located at one end of the bottom plate 29 and is provided with a horizontal strip groove 23, and a plurality of sliders 24 are slidably connected in the strip groove 23, and the top of the slider 24 is rotatably connected to two blocking plates 25 via a rotating shaft, and two adjacent blocking plates 25 are rotatably connected via a hinge.

[0040] It should be noted that, by providing a foldable anti-fall guardrail 6, the anti-fall guardrail 6 can be folded up when not in use, so that the space on the bed board 1 is larger, which is convenient for stretching arms. When sleeping, the anti-fall guardrail 6 can be unfolded to act as a barrier, effectively preventing students from falling off the bed. When students do not want to use the anti-fall guardrail 6 for barrier, they can push the pull plate 26 to the position of the storage slot 7 so that multiple blocking plates 25 are stacked together, so that the space on the bed is larger, which is convenient for stretching arms. When students sleep, they can pull the pull plate 26 to cause multiple blocking plates 25 to be unfolded to form a fence, so that the end close to the outside is completely blocked, preventing students from falling off the bed.

[0041] The side wall of the blocking plate 25 at one end of the anti-fall guardrail 6 is fixedly connected to the support column 2, and the side wall of the blocking plate 25 at the other end of the anti-fall guardrail 6 is fixedly connected with a pull plate 26. The side wall of the support column 2 at one end of the climbing ladder 3 of the bed board 1 is provided with two connecting holes 27, and the surface of the pull plate 26 is provided with two locking bolts 28. The end of the locking bolt 28 is threadedly connected to the inside of the connecting hole 27, and the pull plate 26 is fixedly connected to the support column 2 through the locking bolt 28.

[0042] It should be noted that when the students unfold the anti-fall guardrail 6, the pull plate 26 is located at the position of the support column 2. At this time, the locking bolt 28 on the pull plate 26 corresponds to the position of the connecting hole 27 on the support column 2. At this time, it is only necessary to tighten the locking bolt 28 to fix the pull plate 26 and the support column 2.

[0043] Both ends of the bottom of the supporting top plate 8 are symmetrically fixedly connected to the limiting posts 19 , and the desktop plate 13 is slidably connected between the four limiting posts 19 .

[0044] It should be noted that the limit columns 19 at both ends of the bottom of the supporting top plate 8 are located above the edge of the bed board 1, which does not affect the activities of students on the bed board 1. The four limit columns 19 are used to limit the desktop board 13 during the lifting process, ensuring the stable lifting of the desktop board 13, making the position of the desktop board 13 more stable, and making it convenient for students to use.

[0045] A limiting rod 22 is symmetrically fixedly connected between the two fixing plates 15 and located outside the bidirectional screw 16. Limiting holes are symmetrically opened on both sides of the sliding block 17. The limiting rod 22 is slidably connected in the limiting hole, and the sliding block 17 is slidably connected to the outside of the limiting rod 22.

[0046] It should be noted that the limiting rod 22 serves to limit the movement of the sliding block 17 during the movement of the sliding block 17 , thereby ensuring the smooth movement of the sliding block 17 .

[0047] The tops of the four support columns 2 are all provided with lifting grooves, the four corners of the bottom of the desktop panel 13 are fixedly connected with adjustment columns 9, and the adjustment columns 9 are slidably connected in the lifting grooves on the tops of the support columns 2, and the surfaces of the adjustment columns 9 are equidistantly provided with fixing holes 10, the tops of the support columns 2 are provided with positioning bolts 11, and the ends of the positioning bolts 11 are threadedly connected inside the fixing holes 10, and the adjusting columns 9 are fixedly connected to the support columns 2 via the positioning bolts 11.

[0048] It should be noted that by coordinating the adjustment column 9, the positioning bolt 11 and the support column 2, the height of the desktop panel 13 can be adjusted. The desktop panel 13 can be lowered when needed to facilitate the placement of books and water cups, which is convenient for students to read in bed. The lighting lamp 14 installed at the bottom of the supporting top plate 8 can provide lighting for the bed, avoiding the situation where the dormitory light is too bright and affects others.
