[0002] A bed is an essential item used in bedrooms, dormitories, hotels, and other similar places. Traditional beds are usually made of wood, which is environmentally friendly, durable, and aesthetically pleasing. Nowadays, many beds are also made of stainless steel, metal, and other materials, which are sturdy, durable, and have a long service life.

[0003] For example, patent application number CN202122228508.5 discloses a high-safety iron frame bed, including a bed frame, bed legs fixed at the four corners of the bottom of the bed frame, and headboards at both ends of the bed frame. The bed frame of the iron frame bed in the prior art is connected by welding. After welding, the bed body is relatively sturdy, but the bed structure cannot be disassembled after welding, making it inconvenient to move. Moreover, if a break occurs at the weld of the bed body, it is not easy to repair. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an easy-to-install iron frame bed. By using bolts to connect the longitudinal beams, cross beams, and corner supports, this utility model facilitates the assembly and disassembly of the bed frame, as well as the transportation of the entire iron frame bed. Installing bolts inside the corner supports reduces the degree of oxidation and rust on the bolts, extending their service life and further facilitating the assembly and disassembly of the bed frame.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install iron frame bed, comprising a bed frame; the bed frame contains a bed body for supporting a mattress, characterized in that the bed frame includes a pair of parallel longitudinal beams and a pair of parallel transverse beams perpendicular to the longitudinal beams, the lower end face of the longitudinal beams is provided with corner legs for supporting and fixing the bed frame, the transverse beams are located on both ends of the longitudinal beams and are detachably connected, and the end walls of the corner legs are detachably connected to the longitudinal beams by bolts.

[0006] Optionally, a through groove is provided through the longitudinal beam, and a first limiting sleeve and a second limiting sleeve are installed in the through groove. The first limiting sleeve and the second limiting sleeve are arranged symmetrically at the top and bottom. A gasket is provided between the first limiting sleeve and the second limiting sleeve. One end of the corner support is inserted into the second limiting sleeve and abuts against the gasket.

[0007] Optionally, the corner support is interference-fitted with the inner wall of the second limiting sleeve.

[0008] Optionally, the gasket has a second through hole for the bolt to pass through, and one end of the corner bracket has a third through hole corresponding to the second through hole. The corner bracket and the gasket are connected by bolts passing through the third through hole and the second through hole in sequence.

[0009] Optionally, the first limiting sleeve and the second limiting sleeve are located on both ends of the gasket and are connected by welding.

[0010] Optionally, the longitudinal beam is provided with a plug rod, one end of which is inserted into the crossbeam and bolted to the crossbeam.

[0011] Optionally, the insert can be a "C" shaped structure.

[0012] Optionally, the two ends of the longitudinal beam are bent outward to form a second connecting rod, and the insert is located inside the second connecting rod. The external connection between the longitudinal beam and the second connecting rod is chamfered.

[0013] Optionally, the insertion rod and the second connecting rod can be connected by welding or bolting.

[0014] Optionally, the longitudinal beam and the second connecting rod are integrally formed.

[0015] In summary, compared with the prior art, the beneficial effects of this solution are as follows: This application strengthens the connection strength and limits the connection between the longitudinal beam and the corner legs and headboard support through the action of the first and second limiting sleeves; at the same time, the screw passes from the inside of the corner legs to the inside of the headboard support, so that the screw is hidden inside, reducing the contact between the screw and the outside air, thereby reducing the degree of oxidation and rusting of the screw, extending the service life of the screw, and thus facilitating the disassembly and installation of the corner legs and the bed frame support.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] refer to Figure 1-8 A type of iron-framed bed includes a bed frame and a bed body. The bed frame is rectangular and includes a pair of parallel longitudinal beams 1 and a pair of parallel transverse beams 2 perpendicular to the longitudinal beams 1. The transverse beams 2 and longitudinal beams 1 form a frame structure. The length of the longitudinal beams 1 is greater than the length of the transverse beams 2. The bottom of each of the two longitudinal beams 1 is symmetrically provided with corner legs 3. The bed body includes crossbars 4 and vertical bars 5. The vertical bars 5 are parallel to the longitudinal beams 1 and are located between the two longitudinal beams 1, with both ends of the vertical bars 5 detachably connected to the transverse beams 2. The crossbars 4 are parallel to the transverse beams 2 and are located between the two transverse beams 2, with both ends of the transverse bars 4 detachably connected to the longitudinal beams 1. The longitudinal beams 1 and crossbars 4, and the transverse beams 2 and vertical bars 5, can be connected by bolts to facilitate installation and disassembly. Support plates 6 are provided on the opposite end faces of the two longitudinal beams 1. The height of the support plates 6 from the ground is the same as the height of the vertical bars 5 from the ground, while the height of the bed frame from the ground is greater than the height of the vertical bars 5 from the ground. With the cooperation of the support plate 6 and the vertical rod 5, the mattress can be installed on the support plate 6 and the vertical rod 5. The support plate 6 and the vertical rod 5 can effectively support the mattress. At the same time, the bed frame wraps around the mattress and limits its position, preventing the mattress from falling off the bed frame due to human error. This ensures that the customer will not slip off the bed due to the mattress falling, thus ensuring the customer's safety and allowing the customer to rest and sleep on the mattress with peace of mind.

[0027] refer to Figure 1-4The vertical rod 5 is supported at the center of the horizontal rod 4. A support leg 7 is located at the lower end of the connection between the horizontal rod 4 and the vertical rod 5. A first through hole 8 for bolts is provided at the connection between the horizontal rod 4 and the vertical rod 5. The support leg 7 is a hollow tube structure and is connected to the horizontal rod 4 and the vertical rod 5 by bolts. This three-way cross-bracing system effectively improves the support for the mattress. Simultaneously, the cross-bracing increases the overall rigidity and stability of the bed frame, distributes pressure on the mattress, reduces localized deformation of the bed frame, and ensures more even pressure distribution on the mattress, extending the lifespan of both the mattress and the bed frame. Furthermore, this cross-bracing system reduces the number of support legs 7 and vertical rods 5, simplifying the overall structure, reducing manufacturing costs, and decreasing the overall size and weight.

[0028] refer to Figure 3 The horizontal bar 4 is inclined upwards at both ends to form diagonal bars 9. The ends of the diagonal bars 9 are provided with first connecting rods 10. The ends of the two first connecting rods 10 are respectively connected to the longitudinal beams 1 on both sides by bolts. The first connecting rods 10 are located on the bottom end surface of the longitudinal beams 1. The setting of the first connecting rods 10 can strengthen the connection strength of the longitudinal beams 1, thereby providing good support for the longitudinal beams 1.

[0029] refer to Figure 1 , 5 One of the crossbeams 2 has a headboard support 11 at its top. The headboard support 11 has a "C"-shaped structure, with chamfered edges at the bends. A first positioning rod 12 is fixed to the headboard support 11, and a second positioning rod 13 corresponding to the first positioning rod 12 is provided on the crossbeam 2. A support rod 14 is sleeved between the first positioning rod 12 and the second positioning rod 13. The support rod 14 has a hollow tube structure, and its two ends are bolted to the first positioning rod 12 and the second positioning rod 13, respectively. The support rod 14 provides support for the headboard support 11, strengthening the connection between the headboard support 11 and the crossbeam 2.

[0030] refer to Figure 1 , 5 -8. The two ends of the longitudinal beam 1 are bent outward to form a second connecting rod 15. One end of the second connecting rod 15 is provided with an insert rod 16. Both the insert rod 16 and the crossbeam 2 are provided with a first threaded hole 17. One end of the insert rod 16 is inserted into the crossbeam 2 and connected by bolts. The longitudinal beam 1 and the second connecting rod 15 are integrally formed structures or connected together by welding. The second connecting rod 15 and the insert rod 16 are connected by welding or bolts.

[0031] The external connection between the longitudinal beam 1 and the second connecting rod 15 is chamfered. This prevents customers from colliding with the longitudinal beam 1 and getting injured, thus reducing safety hazards.

[0032] refer to Figure 6-8The corner support leg 3 is a hollow tube structure. A through groove 18 is provided at the bends at both ends of the longitudinal beam 1. This through groove 18 is formed by the merging of the longitudinal beam 1 and the second connecting rod 15. In other words, a semi-circular arc groove is provided at the ends of the longitudinal beam 1 and the second connecting rod 15. When the longitudinal beam 1 and the second connecting rod 15 are welded together, the two semi-circular arc grooves fit together to form a through groove 18. A first limiting sleeve 19 and a second limiting sleeve 20 are fixedly installed inside the through groove 18. The first limiting sleeve 19 and the second limiting sleeve 20 are symmetrically arranged vertically. A gasket 21 is installed between the first limiting sleeve 19 and the second limiting sleeve 20. The gasket 21 is used to separate the first limiting sleeve 19 and the second limiting sleeve 20. The first limiting sleeve 19 and the second limiting sleeve 20 are located on the two end faces of the gasket 21, respectively. The first limiting sleeve 19, the second limiting sleeve 20, and the gasket 21 are all made of metal and can be connected by welding. After the three are connected together, they form a limiting clamp. Before installing the headboard support 11 and the corner legs 3, the limiting clamp is first inserted into the longitudinal beam 1 and located in the through groove 18. The two ends of the gasket 21 are respectively inserted into the longitudinal beam 1 and the second connecting rod 15, and rub against the inner walls of the longitudinal beam 1 and the second connecting rod 15, thus limiting and positioning the limiting clamp. After the limiting clamp is installed, the longitudinal beam 1 and the second connecting rod 15 are welded together. The headboard support 11 and the corner legs 3 are respectively inserted into the first limiting sleeve 19 and the second limiting sleeve 20, and both abut against the gasket 21. Both the gasket 21 and the headboard support 11 have a second through hole 22 that mates with the screw 24. The corner legs 3 have a third through hole 23 that mates with the second through hole 22. The second through hole 22 has threads. A cover is provided at the end of the longitudinal beam 1 away from the headboard support 11 to seal the through groove 18. The longitudinal beam 1 is connected to the corner support leg 3 and the headboard support 11 by passing the screw 24 sequentially through the third through hole 23, the second through hole 22 on the corner support leg 3, and the second through hole 22 on the headboard support 11. The first limiting sleeve 19 and the second limiting sleeve 20 strengthen the connection and limit the movement between the longitudinal beam 1, the corner support leg 3, and the headboard support 11. Simultaneously, the screw 24 passes from inside the corner support leg 3 into the headboard support 11, concealing it internally and reducing its contact with outside air. This reduces oxidation and rust, extends the lifespan of the screw 24, and facilitates the disassembly and installation of the corner support leg 3 and the bed frame.

[0033] The inner diameter of the first limiting sleeve 19 is greater than or equal to the outer diameter of the headboard support 11, and the inner diameter of the second limiting sleeve 20 is greater than or equal to the outer diameter of the corner support 3. This ensures a tight fit between the headboard support 11 or the corner support 3 and the first limiting sleeve 19 or the second limiting sleeve 20, thereby better limiting and securing the headboard support 11 and the corner support 3.

[0034] Finally, it should be noted that the iron frame bed of this utility model, which is easy to install, can be connected and fixed by conventional mechanical connection structures. The control system and connection method required between multiple electrical components and drive components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors.
