Description

Technical Field

[0001] The utility model relates to the technical field of furniture manufacturing, in particular to a tool-free quick disassembly and assembly bed. Background Art

[0002] At present, with the development of e-commerce, online purchase of furniture such as solid wooden beds has also been accepted by customers. Online purchase of solid wooden beds is usually divided into multiple components such as bed cross boards, bed legs, bed side boards, bed beams and bed boards, which are packaged and shipped separately. After receiving the goods, customers need to assemble the above components into a bed.

[0003] When assembling the bed side panels on the bed legs and the bed beams on the bed side panels on site, special tools such as an electric drill for drilling holes and installing screws in the wooden bed frame, a square for measuring and ensuring that the corners of the bed are accurately parallel or perpendicular to the wall, and a glue gun for installing plywood or thin wood boards on the wooden bed frame are usually required. This requires certain technical skills from the installers. If the customer needs professional door-to-door installation after receiving the goods, it will affect the convenience of online shopping that can be used after the goods are delivered to the home, and it will also bring certain labor costs to the merchant's after-sales service. However, the above special tools are not often available in households, and customers cannot assemble the bed by themselves without special tools. In view of this, we propose a tool-free quick disassembly and assembly bed. Utility Model Content

[0004] The purpose of the present invention is to provide a tool-free quick disassembly and assembly bed to solve the problems raised in the above background technology.

[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-Figure 5 As shown, one of the purposes of this embodiment is to provide a tool-free quick disassembly and assembly bed, including a middle plate 1, two cross plates 2 are symmetrically arranged on both sides of the middle plate 1, two bed legs 3 are symmetrically fixedly arranged at both ends of the cross plate 2 and the middle plate 1, and the bed legs 3 are pre-installed on the cross plate 2 and the middle plate 1 by screws when the product is produced and shipped. A bed side plate 4 is provided between two adjacent bed legs 3 on the same side near the top, and two hooks 42 are symmetrically fixedly connected at both ends of the bed side plate 4, and the hooks 42 are pre-installed on the bed side plates 4 by screws when the product is produced and shipped. An upper hook groove 43 is opened on the side away from each other of the two hooks 42, and the upper hook groove 43 is an L-shaped structure. A lower hook groove 44 is provided at a position just below the upper hook groove 43, and a slot 31 is provided on the bed leg 3 at a position corresponding to the bed side panel 4. Two hooks 42 fixed on the bed side panel 4 are slidably set in the corresponding slots 31 respectively, and a positioning rod 32 is fixed at a position corresponding to the upper hook groove 43 and the lower hook groove 44 in the slot 31. After the hook 42 is inserted into the slot 31, the upper hook groove 43 and the lower hook groove 44 are hooked with the positioning rod 32 inside the slot 31. Through the hook 42 and the slot 31, a bed frame is formed between the horizontal plate, the middle plate 1, the bed side panel 4 and several bed legs 3, so that the user can assemble the bed easily and reduce the difficulty of bed assembly.

[0033] When assembling the various components into a complete bed, the user first installs the two ends of the four bedside panels 4 on the six bed legs 3 in sequence. The installation steps are as follows: insert the hook 42 at one end of the bedside panel 4 horizontally into the slot 31, so that the positioning rod 32 at the top of the slot 31 passes through the horizontal section of the upper hook groove 43 and enters the corner of the upper hook groove 43. At this time, the positioning rod 32 at the bottom is located directly below the lower hook groove 44, and the side walls of the bedside panel 4 and the bed legs 3 are in contact. Then press the bedside panel 4 downward to make the positioning rod 32 at the top 2 contacts the top surface of the upper hook groove 43. At this time, the lower hook groove 44 is sleeved on the outer side of the positioning rod 32 located below. The upper hook groove 43, the lower hook groove 44 and the two positioning rods 32 cooperate to limit the rotation of the bed side panels 4, so that the bed side panels 4 remain perpendicular to the bed legs 3. In this way, the assembly of the bed side panels 4 and the bed legs 3 is completed. The bed side panels 4, the bed legs 3, the cross panel 2 and the middle panel 1 constitute the bed frame. By making the lower ends of the six bed legs 3 touch the ground, the bed frame can be firmly placed on the ground, which is convenient for the user to assemble the remaining components on the bed frame later.

[0034] The remaining parts of the bed include two bed beams 6 arranged on both sides of the middle plate 1, and the two bed beams 6 are respectively arranged between the middle plate 1 and the cross plate 2. The side plate 4 is fixedly connected to the side close to the bed beam 6 with a clamping sleeve 41. The clamping sleeve 41 is a U-shaped structure. The two ends of the bed beam 6 are respectively slidably arranged inside the corresponding clamping sleeve 41. When installing the bed beam 6, the two ends of the bed beam 6 are respectively inserted into the inside of the two clamping sleeves 41 from top to bottom until the two ends of the bed beam 6 contact the bottom surface of the inside of the clamping sleeve 41. Then the bed beam 6 can be assembled on the bed frame. The remaining parts of the bed also include several bed boards 5. To facilitate the assembly of the bed boards 5, support bars 11 are fixedly connected to the side where the middle plate 1 and the cross plate 2 are close to each other. Several bed boards 5 are placed in a horizontal array on the bed The upper surface of the beam 6 and the two ends of the bed board 5 are in contact with the upper surfaces of the support bars 11 on the middle board 1 and the cross board 2 respectively. After laying several bed boards 5 on the two support bars 11 on the middle board 1 and the cross board 2 at a certain interval, the assembly of the bed can be completed. The middle position of the bottom of the bed board 5 is in contact with the bed beam 6, so that the bed beam 6 supports the bed board 5, preventing the bed board 5 from breaking under pressure, thereby improving the structural strength of the bed, and thus improving the safety of the user when sleeping on the bed. At this time, the upper surfaces of the middle board 1, cross board 2, bed legs 3, bed side boards 4 and bed boards 5 are all on the same horizontal plane. After the user lays the mattress on the bed, the mattress can be kept flat, which improves the comfort of the user sleeping on the mattress.

[0035] The components used to assemble the bed include a middle plate 1 with pre-installed bed legs 3 and two cross plates 2, four bed side plates 4, two bed beams 6 and several bed boards 5. Each component can be packaged into smaller goods, which is suitable for the fast transportation needs of e-commerce sales. A quick disassembly and assembly structure composed of hooks 42 and positioning rods 32 is provided between the bed legs 3 and the bed side plates 4, which makes it convenient for users to install the bed side plates 4 on the bed legs 3. At the same time, the bed beams 6 can also be quickly installed on the bed side plates 4 through the clamping sleeves 41. The user can complete the assembly of the bed without using any installation tools, which optimizes the user's experience.

[0036] Example 2

[0037] In order to improve the stability of the bed during use, some structures are optimized based on Example 1. Please refer to Figures 1-4 ,as well as Figure 6 and Figure 7, two reinforcing rib assemblies 7 are provided at the bottom of the bed side board 4 near both ends. The reinforcing rib assembly 7 can enhance the structural strength of the bed legs 3 and the bed side board 4 at the four corners after assembly, reduce the shaking amplitude of the bed when the bed is subjected to horizontal force, and improve the comfort of the user sleeping on the bed. The structure of the reinforcing rib assembly 7 is refined as follows. The reinforcing rib assembly 7 includes a rotating plate 71 hinged to the bottom of the bed side board 4, an installation cavity 72 is provided inside the rotating plate 71, and a side groove 73 is provided on the side wall of the rotating plate 71. The positions on both sides of the rotating plate 71 away from the hinge of the rotating plate 71 and the bed side board 4 are aligned. There are two guide grooves 74, which are connected to the interior of the installation cavity 72. A sleeve 77 is slidably provided inside the guide groove 74. A partition 78 is provided between the two sleeves 77. The partition 78 is fixed on the side wall of the installation cavity 72. A small spring 79 is fixed between the partition 78 and the sleeve 77. The small spring 79 pulls one end of the sleeve 77 into the interior of the installation cavity 72. At the same time, a pull rod 75 is slidably provided inside the installation cavity 72. The pull rod 75 is an L-shaped structure. One end of the pull rod 75 passes through the side groove 73 and extends to the outside of the rotating plate 71. A large spring 76 is fixedly connected between the corner of the pull rod 75 and the inner wall of the installation cavity 72, and a wedge 771 is fixedly connected to the side of the sleeve 77 close to the pull rod 75. The wedge 771 is arranged inside the installation cavity 72, and the side of the wedge 771 close to the pull rod 75 is set as an inclined surface. The large spring 76 is used to push the pull rod 75 close to the wedge 771. After the end of the pull rod 75 away from the large spring 76 slides in contact with the inclined surface of the wedge 771, the pull rod 75 squeezes the wedge 771. At this time, the small spring 79 is in an elastically stretched state, but the rebound force of the small spring 79 is less than that of the large spring 76, making the small spring The spring 79 cannot rebound and pulls the sleeve 77 close to the partition 78. The wedge block 771 drives the sleeve 77 to extend out of the guide groove 74. At the same time, a movable groove 33 is opened on the side of the four bed legs 3 located at the four corners close to the bed side board 4. Two card holes 34 are symmetrically opened on the inner wall of the movable groove 33. The sleeve 77 and the card hole 34 cooperate to form a quick installation structure of the rotating plate 71. When the user rotates the rotating plate 71 and installs one end of the rotating plate 71 on the bed leg 3, the bed leg 3, the bed side board 4 and the rotating plate 71 form a triangular structure, which enhances the structural strength of the bed legs 3 and the bed side board 4 located at the four corners after assembly.

[0038] When the user has assembled the various components into a bed, the user pulls the end of the pull rod 75 located outside the turn plate 71 toward the hinged joint between the turn plate 71 and the bed side panel 4, causing the pull rod 75 to move along the inner wall of the installation cavity 72 toward the direction away from the partition 78. The pull rod 75 presses the large spring 76 to elastically contract the large spring 76. At this time, the wedge block 771 and one end of the pull rod 75 are separated, and the small spring 79 rebounds and drives the sleeve 77 close to the partition 78. One end of the two sleeves 77 enters the interior of the installation cavity 72. Then the user rotates the end of the turn plate 71 away from the hinged joint between the turn plate 71 and the bed side panel 4 to the inside of the movable groove 33. The user then releases the pull rod 75. At this time, the large spring 76 The rebound pushes the pull rod 75 closer to the partition 78. The moving pull rod 75 pushes the two wedge blocks 771 and slides along the inclined surface of the wedge block 771, so that the wedge block 771 drives the corresponding sleeve 77 to move along the inner wall of the guide groove 74 away from the partition 78. The small spring 79 returns to the elastic stretched state. When the distance between the two sleeves 77 is enlarged, the end of the sleeve 77 located outside the rotating plate 71 is slidably set inside the corresponding clamping hole 34. The sleeve 77 and the clamping hole 34 cooperate to clamp one end of the rotating plate 71 inside the movable groove 33, so that the bed legs 3, bed side panels 4 and rotating plate 71 form a triangular structure. Because the triangular structure has stability, the structural strength of the bed legs 3 and bed side panels 4 at the four corners after assembly is enhanced, making the bed less likely to shake.
