Description

Technical Field

[0001] This utility model relates to the field of bed technology, specifically, a double-layer iron frame bed. Background Technology

[0002] Bunk beds are a common type of bed in dormitories. They can save a lot of space in smaller rooms. They consist of upper and lower bunks connected by a ladder, allowing users to climb to the upper bunk.

[0003] A prior art technology discloses a bunk bed structure for dormitories, with authorization publication number CN206699855U. It includes a bunk bed frame, two bed boards, and a ladder. The two bed boards are installed vertically on the bunk bed frame, while the ladder is fixed to the frame. The ladder includes two parallel vertical bars welded to the bunk bed frame. Multiple footrests are horizontally arranged between the two vertical bars, with adjacent footrests parallel and spaced apart. In commercialization, each bunk bed frame is constructed from left and right side tubes and several ribs parallel to the width of the bed.

[0004] However, when installing the upper and lower structures of the bunk bed, it was found that some of the ribs and the left and right side tubes were difficult to position during the installation process. After the ribs were fixedly inserted into one of the side tubes, it was often difficult to align them with the mounting groove of the other side tube. Utility Model Content

[0005] The purpose of this invention is to provide a double-layer iron frame bed to solve the problems existing in the prior art.

[0006] The purpose of this utility model is achieved as follows: a double-layer iron frame bed, comprising an upper frame and a lower frame;

[0007] Both the upper and lower frame bodies include a left-side tube, a right-side tube, and several ribs parallel to the width of the bed. The two ends of each rib are detachably fixed to the left-side and right-side tubes, respectively. The inner side of each right-side or left-side tube has several positioning grooves corresponding to the ribs, and the inner side of each left-side or right-side tube has several fixing grooves corresponding to the ribs. The positioning grooves are elliptical or strip-shaped grooves whose length direction is perpendicular to the length of the bed. Each right-side or left-side tube has two installation positions, which, in order of installation from first to last, are:

[0008] When the right or left tube is in an outward tilted position, one end of the rib strip is movably positioned in the positioning groove, and the other end of the rib strip is fixedly inserted into the fixing groove.

[0009] When the right or left tube is in an upright position, the rib strip is fixedly inserted into the positioning groove.

[0010] The beneficial effects of this utility model are as follows:

[0011] During installation, first fix one end of the rib strip into one of the side tubes and secure it. Then tilt the other side tube so that the other end of the rib strip can be placed in the positioning groove of the other side tube for positioning. This will prevent the rib strip from being difficult to position during installation. The other side tube can be flipped over later so that all the rib strips can be smoothly inserted into the positioning groove of the other side tube. Attached Figure Description

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-10 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1As shown, a double-layer iron frame bed is proposed. As is known from common sense, a double-layer iron frame bed consists of an upper frame and a lower frame, which are its upper and lower structural units, respectively.

[0024] like Figure 6-8 As shown, both the upper and lower frame include a left tube 21, a right tube 19, and several ribs 20 parallel to the width of the bed. The ribs 20 are round rods or tubes. The left tube 21 and the right tube 19 are rectangular tubes (not limited to this type of tube). The two ends of the ribs 20 are detachably fixed to the left tube 21 and the right tube 19, respectively. The inner side of the right tube 19 is provided with several positioning grooves 191 corresponding to the ribs 20. The inner side of the left tube 21 is provided with several fixing grooves corresponding to the ribs 20. The outline of the fixing groove matches the cross-sectional shape of the rib 20. The positioning groove 191 is an elliptical groove (not limited to an elliptical groove) whose length direction is perpendicular to the length direction of the bed.

[0025] The right-side tube 19 has two installation positions, which, in order of installation from first to last, are:

[0026] When the right-side tube 19 is in an outward tilted position, one end of the rib strip 20 is movably positioned and engaged with the positioning groove 191, and the other end of the rib strip 20 is fixedly inserted into the fixing groove of the left-side tube 21.

[0027] Rotate the right tube 19 from the outside to the inside so that when the right tube 19 is in an upright position, the rib strip 20 is fixedly inserted into the positioning groove 191 of the left tube 21.

[0028] When the rib strip 20 is inserted into the left tube 21 and then the right tube 19 is installed, it is often difficult to align it with the mounting hole of the right tube 19. Therefore, an elliptical positioning groove 191 needs to be opened on the inner side of the right tube 19 to facilitate installation.

[0029] like Figure 9 , 10 As shown, during installation, first, the rib strip 20 is fixedly inserted into the fixing groove of the left tube 21; then, the right tube 19 is tilted (refer to...). Figure 3 , 9 As shown, the rib strips 20 are placed into the positioning grooves 191 in sequence, which is equivalent to initially inserting the rib strips 20 into the positioning grooves 191 for positioning, so as to avoid the phenomenon that the rib strips 20 are difficult to align with the positioning grooves 191; then, the right tube 19 is flipped upward. During the flipping of the right tube 19, the rib strips 20 continue to be inserted into the positioning grooves 191 of the right tube 19. After the right tube 19 is flipped upward into place, the rib strips 20 are fully inserted into the positioning grooves 191 of the right tube 19. Then, the end position of the right tube 19 is completely fixed, and the installation operation of the rib strips 20 is completed.

[0030] The bed frame also includes four rectangularly distributed, upright bed leg tubes 1 that support the ground and are fixedly connected to the upper and lower frames. The ends of the right-side tube 19 and the left-side tube 21 are detachably fixed to the bed leg tubes 1. The bed leg tube 1 is a single tube column (most on the market are assembled from multiple sections), thus simplifying the bed leg processing procedure and facilitating customer installation. In this embodiment, both the upper and lower frames are detachable, modular structures that can be disassembled and reassembled into a rectangular packaging structure to fit the internal space of a rectangular packaging box, facilitating transportation and resulting in a small packaging size that meets specific packaging and transportation requirements (such as...). Figure 5 (As shown). The diameter of the foot tube 1 is relatively large, and the internal space of the foot tube 1 can accommodate several thinner rods, which reduces the packaging size while still meeting transportation requirements.

[0031] The bed is also equipped with a ladder 17 for users to climb up and down. The upper right tube 5 and the lower right tube 13 are detachably and fixedly connected to the upper and lower ends of the ladder 17, respectively.

[0032] Each end of the right-side tube 19 is provided with an end plate having a first fixing hole 192 and a second fixing hole 193. The first fixing hole 192 is located below the second fixing hole 193. During installation, the fastening bolt needs to pass through the first fixing hole 192 and the second fixing hole 193 to fix the right-side tube 19 to the bed leg tube 1. When the right-side tube 19 is in an outward tilted position, the end of the right-side tube 19 is rotatably connected to the bed leg tube 1 and uses the first fixing hole 192 as the rotation base point. The bolt in the first fixing hole 192 is not locked and only rotates. When the right-side tube 19 rotates to an upright position with the first fixing hole 192 as the base point, the rib strip 20 is fully inserted into the positioning groove 191 of the right-side tube 19. The end of the right-side tube 19 is connected to the bed leg tube 1 through the second fixing hole 193. That is, both the second fixing hole 193 and the first fixing hole 192 need to pass through bolts so that the two ends of the right-side tube 19 are fixedly connected to the bed leg tubes 1 on both sides.

[0033] The aforementioned rib strip 20 is divided into several upper rib strips 7 and several lower rib strips 16. The left side tube 21 is divided into upper left side tube 9 and lower left side tube 12. The right side tube 19 is divided into upper right side tube 5 and lower right side tube 13. The upper rib strips 7, upper left side tube 9 and upper right side tube 5 belong to the upper frame, and the lower rib strips 16, lower left side tube 12 and lower right side tube 13 belong to the lower frame.

[0034] All upper ribs 7 are divided into longer upper ribs 7 and shorter upper ribs 7. The two ends of the longer upper ribs 7 are detachably fixed and connected to the upper left tube 9 and the upper right tube 5, respectively.

[0035] All the lower ribs 16 are divided into longer lower ribs 16 and shorter lower ribs 16. The two ends of the longer lower ribs 16 are respectively detachably fixed to the lower left tube 12 and the lower right tube 13.

[0036] The ends of the shorter upper rib strip 7 and the shorter lower rib strip 16 are both fixedly wrapped with sealing sleeves 18 made of plastic. The sealing sleeves 18 have two advantages:

[0037] 1. To prevent the rib strips from directly contacting the side tubes during use and generating noise;

[0038] Second, it serves a protective function, preventing scratches caused by collisions between pipe fittings during transportation.

[0039] like Figure 1 As shown, the lower frame includes a lower front guardrail 10, a lower rear guardrail 11, a middle lower support rod 14, and a middle bed leg 15. The lower front guardrail 10 and lower rear guardrail 11 are detachably fixed to the bed leg tubes 1 at both ends. The middle lower support rod 14 is parallel to the length of the bed, and its two ends are detachably fixed to the lower front guardrail 10 and lower rear guardrail 11, respectively. The middle lower support rod 14 supports the lower rib slats 16, as shown. Figure 4 As shown, the middle bed leg 15 is detachably fixed to and supports the middle lower support rod 14. There are two middle bed legs 15. The bottom of the middle bed leg 15 and the bottom of the bed leg tube 1 support the ground together. A U-shaped plate is fixed to the top of the middle bed leg 15. The U-shaped plate locks the middle lower support rod 14 to prevent the middle bed leg 15 from rotating. Only one more screw is needed to fix the middle bed leg 15 to the middle lower support rod 14.

[0040] The upper side of the aforementioned intermediate lower support rod 14 is fitted with a flexible pad that flexibly contacts the lower rib strip 16. The flexible pad can be EVA foam or other flexible parts, which are not limited here.

[0041] The aforementioned upper frame is equipped with an upper front guardrail 2, an upper rear guardrail 3, and a middle upper support rod 6. It is also equipped with an upper left guardrail 8 and an upper right guardrail 4. The upper front guardrail 2 and the upper rear guardrail 3 are detachably and fixedly connected to the bed leg tubes 1 at both ends. The upper left guardrail 8 is fixedly connected to the upper left tube 9, and the upper right guardrail 4 is fixedly connected to the upper right tube 5. The middle upper support rod 6 is parallel to the length of the bed, and the upper front guardrail 2 and the upper rear guardrail 3 are detachably and fixedly connected to both ends of the middle upper support rod 6. The middle upper support rod 6 supports the upper rib strips 7.

[0042] The upper side of the aforementioned middle upper support rod 6 is fitted with a flexible pad that flexibly contacts the upper rib strip 7. The flexible pad can be EVA foam or other flexible parts, which are not limited here.

[0043] like Figure 2 The diagram shows the assembly process of the entire bed, combined with... Figure 1 As shown, the specific steps are as follows.

[0044] 1. The upper front guardrail 2 and the lower front guardrail 10 are connected to two of the bed leg tubes 1 by screws to form a front assembly frame. The upper rear guardrail 3 and the lower rear guardrail 11 are connected to the other two bed leg tubes 1 by screws to form a rear assembly frame.

[0045] 2. Connect the middle lower support rod 14 to the two middle bed legs 15 with screws;

[0046] 3. The upper left guardrail 8, the lower left tube 12, the middle upper support rod 6, and the middle lower support rod 14 are connected to the front and rear assembly frames (formed in the first step) by screws.

[0047] 4. Attach EVA foam (flexible pad) to the upper side of the middle upper support rod 6 and the middle lower support rod 14;

[0048] 5. Insert the upper rib strip 7 and the lower rib strip 16 into the fixing groove of the upper left tube 9 and the fixing groove of the lower left tube 12, respectively;

[0049] 6. Insert the upper rib strip 7 and the lower rib strip 16 into the positioning grooves 191 of the upper right side tube 5 and the lower right side tube 13 respectively. Connect the upper right side tube 5 and the lower right side tube 1 to the two bed leg tubes 1 with screws. Fix all the longer rib strips 20 with screws.

[0050] 7. After fixing the positions of the upper right pipe 5 and the lower right pipe 13, install the escalator 17. The upper and lower ends of the escalator 17 are respectively fixed to the upper right pipe 5 and the lower right pipe 13 with screws.

[0051] After going through the above steps, the installation of the entire bed is complete.
