Technical Field
[0001] The utility model relates to the technical field of daily beds, in particular to a novel bed frame. Background Art
[0002] Dormitories mostly use two-layer bed frames, which usually include four columns, two left and right side beams connecting the four columns, two front and rear cross beams, and multiple cross bars connecting the two side beams, and a bed board laid on the cross bars. The structure of the upper and lower beds is the same. The connection between the side beams, cross beams and columns of the bed frames that are now common on the market is completed by bolts and nuts. It is troublesome and time-consuming to disassemble and assemble. In addition, users will inevitably shake the bed after long-term use, and the bolt and nut connection may loosen, causing the side beams and cross beams to suddenly fall out. Especially for the bunk beds in student dormitories, one side is against the wall and the other side is facing outward. When students get on and off, it is difficult to avoid pulling the outer beams of the bed outward, and it is also possible to lift the side beams upward, which will affect the reliability of the bolt and nut connection structure. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a new bed frame which has a simple structure, is easy to assemble and disassemble and can greatly improve the safety of use.

[0006] Furthermore, the clamping hole also includes a transition hole formed by a smooth transition between the through hole and the supporting hole.
[0007] Furthermore, the transition hole is an arc-shaped hole formed by transverse bending, and a side wall of the transition hole forms a stop bulge with smooth transition.
[0008] Furthermore, it also includes a cross beam, there are four columns, the side beams and the cross beams each have two oppositely arranged, the two ends of the side beams and the cross beams are protruding with the hooks, the four columns are right-angled columns, and the two right-angled end faces of the columns are provided with the hook holes.
[0009] Furthermore, the stop bosses on the upright posts corresponding to the two side beams and the cross beam are all located at the relatively outer sides of the corresponding supporting rods.
[0010] Furthermore, a support beam is tightly mounted between two side beams arranged opposite to each other, and clamping holes are provided on opposite sides of the side beams. Inverted L-shaped clamping pieces corresponding to the clamping holes are protruded from both ends of the support beam.
[0011] Furthermore, the back side of the end head is a gradually decreasing slope.
[0012] Furthermore, the end of each of the side beams or cross beams is provided with two upper and lower hooks.

DETAILED DESCRIPTION
[0026] refer to Figures 1 to 9 As shown, a novel bed frame is shown, comprising a column (1) and a side beam (2), wherein a clamping hole (11) is provided on the side of the column (1), and a clamping hook (3) is protruding from the end of the side beam (2), wherein the clamping hook (3) comprises an end head (31) and a supporting rod (32) of a reduced size, and the clamping hole (11) comprises a through hole (111) at the top through which the end head (31) can pass, and a supporting hole (112) connected to the bottom to accommodate the supporting rod (32).
[0027] As shown in the accompanying drawings, the clamping hole 11 is a closed hole that is larger at the top and smaller at the bottom. Since the outer contour size of the end head 31 is larger than the outer contour size of the supporting rod 32, when installing, the end head 31 is directly inserted into the through hole 111, and the supporting rod 32 can slide downward from the through hole 111 and enter the reduced supporting hole 112 by pressing down or the side beam 2's own gravity. Under the action of gravity, the side beam 2 is firmly clamped in the supporting hole 112. The entire installation process does not require the use of bolts and nuts, and the operation is simple and convenient. Moreover, even if the side beam 2 is lifted upward during use, as long as it is not pulled outward at the same time, the side beam 2 will not fall out at all, which greatly improves the safety of the bed frame. When it is necessary to disassemble, it is only necessary to lift the side beam 2 upward, so that the supporting rod 32 moves up to the through hole 111, and then apply a force pulling outward at the same time, so that the end head 31 can be pulled out of the through hole 111, and the operation is simple and convenient.
[0028] The positions of the above-mentioned latch hole 11 and the latch hook 3 can also be interchanged, that is, the latch hole 11 is opened at the end of the side beam 2, and the latch hook 3 is protruded on the side of the stand 1.
[0029] Furthermore, the clamping hole (11) further comprises a transition hole (113) formed by a smooth transition between the through hole (111) and the supporting hole (112).
[0030] As shown in the accompanying drawings, the through hole (111) is at the top, the supporting hole 112 is at the bottom, and the transition hole 113 is in the middle. The transition hole 113 is a long hole that is wide at the top and narrow at the bottom, and the upper and lower hole walls of the transition hole 113 are smoothly transitioned with the through hole 111 and the supporting hole 112 respectively, so that the supporting rod 32 can slide up and down more smoothly.
[0031] Furthermore, the transition hole (113) is an arc-shaped hole formed by transverse bending, and a side wall of the transition hole (113) forms a stop protrusion (114) with smooth transition.
[0032] As shown in the accompanying drawings, the width of the transition hole 113 is at least between the widths of the supporting hole 112 and the through hole 111, so that the supporting rod 32 can smoothly enter the supporting hole 112 from the through hole 111 through the transition hole 113. The transition hole 113 is actually a curved hole formed by smoothly bending to one side when transitioning from the through hole 111 to the supporting hole 112. The curvature radius of the hole wall on one side of the curved hole is smaller than the curvature radius of the hole wall on the other side. The stop convex 114 is a protruding hole wall on the side with a smaller curvature radius. When the supporting rod 32 enters the supporting hole 112, the stop convex 114 plays a certain limiting role above the supporting rod 32. When the supporting rod 32 is lifted, if there is no outward component force relative to the stop convex 114, the purpose of lifting the supporting rod 32 cannot be achieved, thereby preventing the occurrence of involuntary lifting pranks. Since the stop protrusion 114 is smoothly transitioned, when the side beam 2 is lifted upward under the action of external force, the supporting rod 32 can smoothly move along the contour of the stop protrusion 114 with a smooth transition.
[0033] Furthermore, it also includes a cross beam (4), the vertical column (1) has four, the side beam (2) and the cross beam (4) each have two oppositely arranged ones, the side beam (2) and the cross beam (4) are both provided with the hook (3) at both ends, the four vertical columns (1) are right-angled columns, and the two right-angled end faces of the vertical column (1) are both provided with the hook hole (11).
[0034] As shown in the attached drawings, there are hooks 3 at the front and rear ends of the two side beams 2 and the left and right ends of the two cross beams 4. The four uprights 1, the two side beams 2 and the cross beams 4 are arranged to form a complete bed frame. The two right-angled surfaces of the right-angled uprights 1 are respectively connected to a side beam 2 and a cross beam 4. This connection type adopts the clamping method of the hook 3 and the clamping hole 11. The entire installation process does not require bolts and nuts. The operation is simple and convenient. Moreover, the parts are convenient to classify, pack and transport after disassembly.
[0035] Furthermore, the stop protrusions (114) on the upright posts (1) corresponding to the two side beams (2) and the cross beam (4) are all located on the relatively outer sides of the corresponding supporting rods (32).
[0036] As shown in the attached drawings, the hooks 3 at the front and rear ends of the side beams 2 that are opposite to each other correspond to the hook holes 11 on the two left and right columns 1 that are opposite to each other, wherein the transition holes 113 of the two opposite hook holes 11 are bent toward the inside of the bed frame, that is, the stop convex 114 is the corresponding protruding hole wall on the transition hole 113 that is opposite to the outside of the bed frame. The advantage of this arrangement is that when the side beams 2 need to be disassembled upward, it is necessary to simultaneously apply a thrust to the side beams 2 into the bed frame so that the supporting rod 32 can bypass the corresponding stop convex 114 and enter the transition hole 113. In real life, there are bed boards and the like inside the bed frame to support the side beams 2 on both sides, so when the side beams 2 are pulled outward or lifted upward by accident, the side beams 2 will not fall out, thereby greatly improving the safety of the bed frame. The cross beam 4 has a similar structure to the side beams 2.
[0037] Furthermore, a support beam (5) is tightly mounted between two side beams (2) arranged opposite to each other, a clamping hole (21) is provided on the opposite side of the side beam (2), and inverted L-shaped clamping pieces (51) corresponding to the clamping holes (21) are protruded from both ends of the support beam (5).
[0038] As shown in the accompanying drawings, a plurality of support beams 5 can be provided with gaps along the length direction of the side beams 2. Specifically, a snap-in hole 21 is opened on the opposite side surfaces of the side beams 2, and both ends of the support beam 5 are provided with inverted L-shaped snap-in pieces 51 that can be snapped into the snap-in holes 21 from top to bottom. After the snap-in pieces 51 at both ends are snapped into the snap-in holes 21, the two end surfaces of the support beam 5 can be tightly pressed between the two side beams 2. When an external force pushes the side beams 2 inward, they cannot be pushed because of the support beams 5, thereby preventing the side beams from being unintentionally dislodged, thereby improving the safety of the bed frame.
[0039] Furthermore, the back side of the end head (31) is a gradually decreasing inclined surface.
[0040] As shown in the accompanying drawings, the end 31 is conical, and its back side gradually narrows from the larger outer edge to the smaller supporting rod 32 to form an inclined surface. When it is clamped downward in the clamping hole 11, the inclined surface can make the clamping smoother. Moreover, when the hooks 3 at the front and rear ends of the side beam 2 are clamped in place, because the bed board is pressed down by gravity, the side beam 2 is slightly stretched and deformed, and the hooks 3 at both ends are tightened. The inclined surface can appropriately fill the gap between the supporting hole 112 and the supporting rod 32 to avoid noise and reduce the processing difficulty of the supporting hole 112 and the supporting rod 32.
[0041] Furthermore, two upper and lower hooks (3) are provided at the ends of the side beam (2) or the cross beam (4).
[0042] As shown in the accompanying drawings, at each end of each side beam 2 or cross beam 4, there are two hooks 3 distributed up and down, and correspondingly, two hook holes 11 are also opened on the side of the column 1 corresponding to each side beam 2 or cross beam 4. In this way, after each side beam 2 or cross beam 4 is connected to the column 1, unnecessary rotation between the single side beam 2 or cross beam 4 and the column 1 can be prevented, making the connection more firm and reliable.
[0043] Furthermore, the hook (3) is a bolt welded or riveted to the end surfaces of the side beam (2) and the cross beam (4).
[0044] As shown in the accompanying drawings, the side beam 2 and the cross beam 4 are made of angle irons, and through holes are opened on one side of the angle irons constituting the end faces. Bolts pass through from the outside to the inside and are fixed by welding or riveting. The material acquisition and use are very simple and convenient.
