Description

Technical Field

[0001] This utility model relates to the field of bed frame technology, and in particular to a bed frame with an adjustable mattress height. Background Technology

[0002] As an important component of bedroom furniture, the bed frame's design and function directly affect the user's sleep experience and space utilization efficiency. Existing bed frame structures typically consist of a main frame and a slatted frame. The slatted frame, as a key component supporting the mattress, plays a crucial role in the overall performance of the bed frame.

[0003] Most bed frames on the market today use a fixed slat design. Once manufactured, the height of this type of fixed slat frame is predetermined and cannot be adjusted according to actual usage needs. While this design ensures the stability of the bed frame structure to some extent, it lacks flexibility and struggles to meet the diverse needs of different user groups and usage scenarios. A bed frame with storage function, disclosed in Chinese Patent Publication No. CN222693049U, is designed primarily to reduce space occupation during transportation and improve the convenience of logistics.

[0004] However, from the perspective of mattress height adjustment, the slatted frame in this bed frame structure remains fixed. Since mattress height requirements may vary in different usage scenarios, a fixed-height slatted frame cannot meet these diverse needs, limiting the flexibility and applicability of the bed frame. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a bed frame with adjustable mattress height to solve the problems of low flexibility and poor applicability of existing bed frames.

[0006] An adjustable mattress height bed frame includes a bed frame body and a slatted frame composed of several support rods. The slatted frame is installed on the inner side of the bed frame body via an adjustable connector. The adjustable connector includes a snap fastener fixed to the end of the support rod and a snap seat fixed on the inner side of the bed frame body. The snap seat is a vertically arranged elongated structure with multiple snap holes arranged vertically. The snap fastener has a buckle for engaging with one of the snap holes.

[0007] The beneficial effects of this utility model are: This invention utilizes a vertical overlapping seat with multi-level overlapping holes located on the inner side of the bed frame body, which cooperates with an overlapping buckle with a latch fixed to the end of the slatted frame support rod. This enables multi-level adjustment of the slatted frame height, allowing for flexible adaptation to different mattress thicknesses and users' personalized needs for bed surface height, significantly improving the applicability and flexibility of the bed frame. Simultaneously, the unique overlapping hole and latch design, through continuous left-right and front-back limiting during engagement and disengagement, effectively prevents jamming during operation, resulting in a smooth, effortless, and reliable adjustment process.

Therefore, they should not be construed as limitations on this utility model.

[0011] Please see Figures 1 to 7 : This embodiment discloses a bed frame with adjustable mattress height, including a bed frame body 1 and a frame structure composed of several support rods 2. The frame structure is installed on the inner side of the bed frame body 1 via adjustable connectors. The adjustable connectors include latches 3 and latch seats 4. The latches 3 are fixed to the ends of the support rods 2 with screws, and the latch seats 4 are fixed to the inner side of the bed frame body 1 with screws. It should be noted that when the support rods 2 are installed horizontally inside the bed frame body 1, the latch seats 4 are fixed on the left and right sides inside the bed frame body 1. When the support rods 2 are installed vertically, the latch seats 4 are fixed on the front and rear sides inside the bed frame body 1. Both ends of the support rods 2 are fixed to the latch seats 4 on the left and right sides or front and rear sides through the latches 3 to form support. Specifically, as shown... Figure 2 As shown, the overlapping seat 4 is a vertically arranged elongated structure with multiple overlapping holes 5 arranged vertically on it. The overlapping buckle 3 has a buckle 6 for engaging with one of the overlapping holes 5. When adjusting the mattress height, simply engage the overlapping buckle 3 with the overlapping holes 5 at different heights, improving the flexibility and applicability of the bed frame. Additionally, as... Figure 3 As shown, the overlapping hole 5 includes a square limiting hole 51 and a square locking hole 52. The locking hole 52 is connected directly below the limiting hole 51 and its width is smaller than the width of the limiting hole 51. Thus, right-angled sides 53 are formed on both sides of the connection between the locking hole 52 and the limiting hole 51. One end of the buckle 6 is connected to the back of the overlapping buckle 3, and the other end extends outward and downward. The buckle 6 includes a connecting part 61 and a guide part 62 connected below the connecting part 61. The width of the guide part 62 is adapted to the width of the limiting hole 51, and the width of the connecting part 61 is adapted to the width of the locking hole 52. When engaging, simply insert the guide part 62 on the buckle 6 into the limiting hole 51 of the overlapping hole 5, and then press down to make the connecting part 61 on the buckle 6 engage in the locking hole 52 of the overlapping hole 5 to form a fixation.

[0012] In this embodiment, as Figure 4 and Figure 5As shown, since the width of the connecting part 61 is smaller than the width of the guide part 62, a vertically extending slide 63 is formed on both sides of the connecting part 61. When the guide part 62 on the buckle 6 extends into the limiting hole 51 of the overlapping hole 5, it forms a left-right limit to prevent the buckle 6 from wobbling left and right. At the same time, it also aligns the connecting part 61 with the locking hole 52. During the downward movement of the buckle 6, since the buckle 6 extends downward at an angle, it can be guided by the inner surface of the guide part 62, so that the right-angled sides 53 on both sides of the connection between the locking hole 52 and the limiting hole 51 slide into the slide 63 on both sides of the connecting part 61, thereby forming a front-back limit. It should be noted here that when the connecting part 61 does not enter the locking hole 51, the right-angled sides 53 on both sides of the connection between the locking hole 52 and the limiting hole 51 slide into the slide 63 on both sides of the connecting part 61, thereby forming a front-back limit. Before step 2, the guide part 62 and the limiting hole 51 cooperate to limit the left and right sides. Only when the connecting part 61 enters the locking hole 52 will the guide part 62 completely pass through the limiting hole 51. At the same time, the two right-angled sides 53 inside the overlapping hole 5 just slide into the slide rails 63 on both sides of the connecting part 61. Therefore, when the guide part 62 completely passes through the limiting hole 51, the connecting part 61 cooperates in the locking hole 52 to form the left and right limit. Thus, it can be determined that during the entire process of the buckle 6 being snapped into the overlapping hole 5, the left and right limit is first formed by the cooperation of the guide part 62 and the limiting hole 51, and then by the cooperation of the connecting part 61 and the locking hole 52. The limit connection is uninterrupted, so there will be no jamming, and the snapping process is smoother and more fluid.

[0013] Furthermore, such as Figure 5 As shown, when the buckle 6 is removed upwards, the right-angled edges 53 on both sides first disengage from the slide rail 63, and then the connecting part 61 disengages from the locking hole 52. After this, there is no left or right limiting for the buckle 6. If the buckle 6 is not removed from the limiting hole 51 at this time, it is easy to get stuck. To avoid this phenomenon, a guide rib 7 is provided between the outer side of the buckle 6 and the back of the overlapping buckle 3. The guide rib 7 is used to abut against the top edge of the limiting hole 51 to form a guide during the process of the buckle 6 disengaging from the overlapping hole 5. Specifically, when the right-angled edge 53 is about to disengage... When sliding along the slide 63, the top of the guide rib 7 abuts against the top of the limiting hole 51, thereby applying an outward force to the buckle 6. At this time, the connecting part 61 is still in the locking hole 52, forming an action limit. Subsequently, this outward force will drive the guide part 62 back into the limiting hole 51 to form a left and right limit. In this way, even if the connecting part 61 is disengaged from the locking hole 52, there will be no interruption in the left and right limit of the buckle 6. Therefore, the connection can be continuously limited without interruption during the process of removing the buckle 6, and there will be no jamming. The removal process is smoother.

[0014] In this embodiment, as Figure 7As shown, when the buckle 6 is engaged in the overlapping hole 5, the guide part 62 will bend outward. Therefore, the overlapping seat 4 is provided with a protrusion 41 that arches outward and extends in the vertical direction. There is a gap between the inner side of the protrusion 41 and the bottom surface of the overlapping seat 4. When the overlapping seat 4 is fixed inside the bed frame body 1, a receiving cavity 42 is formed between the protrusion 41 and the bed frame body 1. In addition, the overlapping hole 5 is provided on the protrusion 41. When the buckle 6 is engaged in the overlapping hole 5, the guide part 62 on the buckle 6 is located in the receiving cavity 42.

[0015] Furthermore, the overlapping buckle 3 has an L-shaped structure, consisting of a longitudinally arranged assembly part 31 and a transversely arranged mounting part 32. The buckle 6 is located on the outside of the assembly part 31, and the overlapping buckle 3 is fixed to the support rod 2 through the mounting part 32.

[0016] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present invention.
