[0002] A bed frame typically consists of a bed frame and a backrest. The backrest is located on one side of the bed frame, and the mattress is placed on top of the bed frame. When using the bed, users usually put a sheet on the mattress. However, the current bed frame cannot be moved. When putting on the sheet, the mattress is located on the side of the backrest, and due to the small gap, it is difficult to insert the sheet. Often, one side of the mattress needs to be lifted to put the sheet on, which is inconvenient. Therefore, there is an urgent need to improve this. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pull-out bed tray. By setting a guide rail assembly inside the base and setting rollers at the bottom of the bed board, with the rollers located inside the guide rail assembly, the bed board can be pulled out, making it convenient to change the bed sheet.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pull-out bed support, including a base support, a bed board on the upper part of the base support, a support strip inside the base support, a guide rail assembly fixed on the upper part of the support strip along its length direction, and a roller corresponding to the guide rail assembly fixed on the lower part of the bed board. The roller is located inside the guide rail assembly and can roll along the guide rail assembly so that the bed board can move above the base support.

[0005] Furthermore, the guide rail assembly includes multiple first guide rails and second guide rails disposed on both sides of the first guide rails. Each first guide rail and each second guide rail is provided with a roller. The first guide rail is provided with a first limiting rib on both sides, the second guide rail is provided with a second limiting rib on one side, and the second limiting rib is provided with a third limiting rib at both ends. The roller can abut against or disengage from the third limiting rib.

[0006] Furthermore, one side of the bed board extends beyond the side of the base support, and a limiting plate is provided at the lower part of that side. The limiting plate is hinged to the bed board, and the limiting plate can abut against or detach from the base support.

[0007] Furthermore, the limiting plate includes a connecting part and a handle part, which are connected by the limiting part. The connecting part is connected to a hinge, and the side of the limiting part can abut against or detach from the inner wall of the base. The handle part is located above the base and extends beyond the outside of the base.

[0008] Furthermore, a U-shaped plate is fixed to the upper part of the base, and the side of the limiting part can abut against the U-shaped plate, wherein the U-shaped plate is a metal plate.

[0009] Furthermore, the limiting plate and the bed board are limited by the first bolt, and the connecting part is provided with a clearance hole. The first bolt passes through the clearance hole and is inserted into the bed board for fixation. The lower part of the connecting part can abut against or disengage from the head of the first bolt.

[0010] Furthermore, a spring is sleeved on the outside of the first bolt, with the upper end of the spring abutting against the lower part of the bed board and the lower end abutting against the upper part of the connecting part.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 7 As shown, this embodiment discloses a pull-out bed tray, including a base tray 1, a bed board 3 on the upper part of the base tray 1, a support strip 11 inside the base tray 1, a guide rail group 2 fixed on the upper part of the support strip 11 along its length direction, and a roller 4 corresponding to the guide rail group 2 fixed on the lower part of the bed board 3. The roller 4 is located in the guide rail group 2 and can roll along the guide rail group 2 so that the bed board 3 can move above the base tray 1. The guide rail group 2 includes a plurality of first guide rails 21 and second guide rails 22 arranged on both sides of the first guide rails 21. Each first guide rail 21 and each second guide rail 22 is provided with a roller 4. First limiting ribs 211 are provided on both sides of the first guide rail 21, second limiting ribs 221 are provided on one side of the second guide rail 22, and third limiting ribs 222 are provided at both ends of the second limiting ribs 221. The roller 4 can abut against or disengage from the third limiting ribs 222.

[0027] The bed board 3 is placed above the base support 1. The rollers 4 at the bottom of the bed board 3 are located in the first guide rail 21 and the second guide rail 22 respectively. When the bed board 3 is pulled out, the rollers 4 can roll on the corresponding guide rail group 2, so that the bed board 3 can move, which is convenient for changing the bed sheet. Furthermore, by setting the first limiting rib 211, the lateral position of the bed board 3 can be limited to prevent the bed board 3 from deviating. By setting the second limiting rib 221 and the third limiting rib 222, the movement distance of the bed board 3 can be limited to prevent the bed board 3 from detaching from the base support 1.

[0028] like Figure 5 and Figure 6 As shown, one side of the bed board 3 extends beyond the side of the base 1, and a limiting plate 6 is provided at the lower part of this side. The limiting plate 6 is a thin metal plate. The limiting plate 6 is hinged to the bed board 3 by a hinge 5. The limiting plate 6 can abut against or detach from the base 1. Specifically, the limiting plate 6 includes a connecting part 61 and a handle part 63. The connecting part 61 and the handle part 63 are connected by a limiting part 62. The connecting part 61 is connected to the hinge 5. The side of the limiting part 62 can abut against or detach from the inner wall of the base 1. The handle part 63 is located above the base 1 and extends beyond the outside of the base 1.

[0029] When the bed board 3 is not needed to be pulled out, the limiting part 62 is located inside the base 1 and abuts against the inner wall of the base 1 on its side. At this time, the bed board 3 is restricted by the limiting part 62 and cannot be pulled out, thus limiting the bed board 3. When the bed board 3 needs to be moved, the handle part 63 is lifted up, and the limiting plate 6 can rotate around the hinge 5 as the axis, so that the limiting part 62 is higher than the base 1. At this time, the bed board 3 can be pulled to move. The operation is convenient and the reliability is good.

[0030] The limiting plate 6 and the bed board 3 are limited by the first bolt 31. The connecting part 61 is provided with a clearance hole 64. The first bolt 31 passes through the clearance hole 64 and is inserted into the bed board 3 for fixation. The lower part of the connecting part 61 can abut or disengage from the head of the first bolt 31. A spring 7 is sleeved on the outside of the first bolt 31. The upper end of the spring 7 abuts against the lower part of the bed board 3 and the lower end abuts against the upper part of the connecting part 61. By setting the first bolt 31, the limiting plate 6 can be prevented from falling. At the same time, by setting the spring 7, not only can the feel of the handle 63 be improved when it is turned upward, but the limiting plate 6 can also be prevented from shaking.

[0031] A U-shaped plate 12 is fixed on the upper part of the base 1. The side of the limiting part 62 can abut against the U-shaped plate 12. The U-shaped plate 12 is a metal plate. Since the base 1 is a wooden structure, the metal U-shaped plate 12 is in direct contact with the limiting plate 6, which can prevent the limiting plate 6 from damaging the base 1.

[0032] like Figure 7As shown, the upper part of the bed board 3 is provided with a cover cloth 8, the upper surface of the bed board 3 is provided with an annular groove 32, and the lower part of the cover cloth 8 is provided with an extension 81. The extension 81 is inserted into the annular groove 32 for limitation. Since the bed board 3 is made of wood, the cover cloth 8 can isolate the mattress from the bed board 3, thereby protecting the mattress. The cooperation between the extension 81 and the annular groove 32 can prevent the cover cloth 8 from curling up.

[0033] The specific fixing method is as follows: a wooden strip 34 is fixed at the lower edge of the bed board 3; multiple insert rods 9 are provided at the extension 81 of the cover cloth 8; a through hole 33 corresponding to the insert rod 9 is provided at the lower part of the annular groove 32; an installation groove 35 corresponding to the through hole 33 is provided at the upper part of the wooden strip 34; the insert rod 9 passes through the through hole 33 and is inserted into the installation groove 35 for fixing; specifically, the insert rod 9 and the wooden strip 34 are fixed by a second bolt 100; a guide hole 91 is provided on the side of the insert rod 9; the second bolt 100 is threadedly connected to the wooden strip 34 and its end is inserted into the guide hole 91.

[0034] The upper end of the insertion rod 9 is fixedly connected to the cover cloth 8 and the insertion rod 9 is not exposed outside the cover cloth 8. The insertion rod 9 is not circular. After the insertion rod 9 is inserted into the mounting groove 35, the second bolt 100 is turned, and the end of the second bolt 100 is inserted into the guide hole 91, thereby fixing the cover cloth 8 to the bed board 3. The lower surface of the guide hole 91 is a slope, so the second bolt 100 can push the insertion rod 9 downward during the fixing process. Specifically, during fixing, the end of the second bolt 100 first contacts the lowest point of the slope. By turning the second bolt 100, the second bolt 100 can move along the slope, thereby pulling the insertion rod 9 downward, so that the cover cloth 8 can be tightly attached to the upper surface of the bed board 3.
