DETAILED DESCRIPTION

[0028] The application will be further described below in combination with the accompanying drawings. Figures 1-4 The application will be further described below in combination with the accompanying drawings.

[0029] As shown in Figure 1 , Figure 2 , the bed frame comprises a bed body 1 and a bed leg 2, the bed body 1 is provided with a plurality of cross rods 3 in the direction from the head to the tail of the bed, in the embodiment, the cross rods 3 are distributed at intervals and parallel to each other.

[0030] As shown in Figure 1 , Figure 2 , the bed frame further comprises a movable rod 4, the movable rod 4 is located between two cross rods 3 and parallel to the cross rods 3.

[0031] The length of the movable rod 4 is slightly less than the length of the crossbar 3, so that there is a gap between the end of the movable rod 4 and the bed 1, and the movable rod 4 can slide vertically relative to the bed.

[0032] like Figure 1 , Figure 2 As shown, the head and foot of the bed frame 1 have pressure rods 5. Several movable rods 4 are connected to the pressure rods 5 through connectors 6, so that the movable rods 4 and the pressure rods 5 can move synchronously. A spring is provided between the connectors 6 and the bed frame 1. The spring applies an upward elastic force to the connectors 6, so that the upper surface of the movable rods 4 is higher than the upper surface of the crossbars 3. A space for holding the bed sheet or mattress is formed between the pressure rods 5 and the bed frame 1.

[0033] like Figure 1 , Figure 3 As shown, the bed 1 has a support frame, and the spring includes a compression spring 8. The lower end of the compression spring 8 is mounted on the support frame 7, and the upper end of the compression spring 8 is connected to or attached to the connector 6.

[0034] Preferably, there are two supports 7, located at the head and foot of the bed frame 1. The connector 6 includes a strip rod, the end of which is connected to the support 7 and can slide along the height of the bed frame.

[0035] In this embodiment, the support 7 is L-shaped and includes a vertical part 71 and a horizontal part 72. The vertical part 71 and the horizontal part 72 are fixed vertically. The vertical part 71 is fixed to the bed frame 1. A sliding groove 73 is provided along the height direction of the bed frame. The end of the strip rod is slidably connected to the sliding groove 73.

[0036] Preferably, the bar includes a body 61 and a slider 62. The slider 62 is fixed to the end of the body 61 and is slidably connected to the groove 73. The movable rod 4 is fixed to the body 61.

[0037] like Figure 1 , Figure 3 As shown, the horizontal part 72 of the bracket has a threaded through hole in the vertical direction. The threaded through hole is threadedly connected to the adjusting bolt 9. The lower end of the compression spring 8 is connected to the upper end of the adjusting bolt 9, and the upper end of the compression spring 8 is rotatably connected to the lower end of the connector 6.

[0038] Specifically, the lower end face of the connector 6 is provided with a circular groove, and a turntable 10 is rotatably disposed in the circular groove. The lower end face of the connector 6 is provided with a retaining ring 11 to support the turntable 10, and the upper end of the compression spring 8 passes through the retaining ring 11 and is connected to the turntable 10.

[0039] The retaining ring 11 can limit the turntable 10 and prevent the turntable 10 from moving downward; the compression spring 8 is connected to the turntable 10, so that the compression spring 8 can rotate relative to the connecting piece 6.

[0040] Alternatively, the bearing can be fixed at the lower end face of the connector 6, and the upper end of the compression spring 8 can be connected to the inner ring of the bearing.

[0041] Rotating the adjusting bolt 9 can compress or stretch the compression spring 8. When the adjusting bolt 9 is rotated toward the side of the connecting piece 6, the compression spring 8 is compressed and applied to the connecting piece 6, causing it to move toward the horizontal bar 3. This drives the movable rod 4 connected to the connecting piece 6 away from the ground, thus achieving the purpose of adjusting the vertical height of the movable rod 4.

[0042] When a mattress or sheet is used above the bed frame, the upper surface of the movable rod 4 can be adjusted to be a suitable distance above the crossbar 3.

[0043] like Figure 2 , Figure 3 , Figure 4 As shown, the connector 6 also includes a connecting rod 63. One end of the connecting rod 63 is fixed to the body 61 and the slider 62. The connecting rod 63 is L-shaped. The other end of the connecting rod 63 is provided with a guide rod 12 along the height direction of the bed frame. A tension spring 13 is sleeved on the guide rod 12. The lower end of the tension spring 13 is connected to the connecting rod 63, and the upper end of the tension spring 13 is connected to the pressure rod 5. The pressure rod 5 has a guide hole that slides with the guide rod 12.

[0044] Preferably, the pressure rod 5 includes a rod body 51, the end of which is provided with a mounting hole, and a top rod 52 that can abut against the bed sheet or mattress is threaded into the mounting hole. The end of the top rod 52 is positioned above the bed frame 1.

[0045] With the top rod 52 designed, it can be further adjusted to accommodate sheets or mattresses of different thicknesses, and the elasticity can be used to press the sheet or mattress onto the cross rod 3.

[0046] The working principle of this embodiment is as follows: In use, the corner of the sheet or mattress can be placed between the pressure rod 5 and the bed frame 1. When a person lies down, the movable rod 4 and connecting piece 6 move downwards, compressing the compression spring 8. The connecting piece 6 then moves the connecting rods 63 on both sides downwards. The connecting rods, through the guide rod 12, pull the top rod 52 towards the bed frame 1, clamping the sheet or mattress and reducing movement of the sheet or mattress due to turning over while sleeping. After getting up, the pressure of the top rod 52 on the sheet or mattress is released by the return of the compression spring 8 and tension spring 13.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
