Description

Technical Field

[0001] The invention relates to the technical field of folding beds, in particular to a guide rail folding bed. Background Art

[0002] A folding bed is a simple bed designed using the principle of joints. For convenience and to save space, it can be folded and stored in various ways. It is convenient and practical, and easy to store. However, the existing folding beds generally do not have a locking device after folding, which makes it easy for the folding bed to be unfolded again; at the same time, the existing self-locking mechanism is an additional component to block the joints of the folding bed, which is complex in structure and high in production cost. Therefore, the guide rail folding bed is designed to simplify the structure and make the self-locking structure of the folding bed simple. Summary of the invention

[0003] The purpose of the present invention is to provide a guide rail folding bed, by forming an arc groove and a limit groove on the side panel, utilizing the limit groove to limit and lock the first folding frame to achieve the self-locking function of the first folding frame, and at the same time providing a first supporting foot, linking the first supporting foot with the first folding frame, and realizing locking or unlocking of the first folding frame by folding or unfolding the first supporting frame.

[0004] The present invention provides the following technical solution: a guide rail folding bed comprises a base frame, side panels are fixed on both sides of the base frame, and a first folding frame is rotatably connected between the side panels via a rotating shaft, and a first guide shaft is fixed to the side surfaces on both sides of one end of the first folding frame, and two symmetrically distributed guide grooves are provided on the inner wall of the side panel, and the guide groove includes an arc groove and a limit groove, and the first guide shaft moves in the guide groove, and a waist hole is provided on the side of the first folding frame, and the rotating shaft is connected in the waist hole. When the first guide shaft moves into the limit groove, the first folding frame is in a vertical state, and the first folding frame is moved up and down in the vertical state, so that the first guide shaft moves to the lower end of the limit groove to lock the first folding frame, and when the first guide shaft moves out of the limit groove and moves into the arc groove, the first folding frame can swing along the arc groove to unfold the first folding frame, and when the first guide shaft moves to the uppermost end of the arc groove, the first folding frame is in a horizontal state.

[0005] Furthermore, the first folding frame is connected to a first hinge via a pin shaft, and a first supporting foot is fixed to the lower end of the first hinge. The first folding frame is supported by the first supporting foot, and the rotation of the first hinge can drive the first supporting foot to rotate and fold, thereby reducing the space occupied by the first supporting foot.

[0006] Furthermore, a connecting rod hole is provided on the first hinge, and a first connecting rod is fixed on the connecting rod hole. The other end of the first connecting rod is fixed on the rotating shaft. The rotation of the first supporting foot drives the first hinge to rotate, so that the first guide shaft of the first folding frame moves into the limiting groove. The rotation of the first hinge drives the first folding frame to move up and down, and moves the first guide shaft into the arc groove or the limiting groove, thereby unlocking or locking the first folding frame.

[0007] Furthermore, a second folding frame is rotatably connected between the two side panels via a rotating shaft. The second folding frame and the first folding frame are linearly symmetrical structures. A second guide shaft is fixed to the side surface of one end of the second folding frame, and the second guide shaft also moves in the guide groove. By setting up a symmetrical second folding frame, the other part of the folding bed can also be folded.

[0008] Furthermore, the second folding frame is also connected to a second hinge via a pin shaft, and a second supporting foot is also fixed to the lower end of the second hinge. The second supporting foot has the same function as the first supporting foot, and is used to support the second folding frame.

[0009] Furthermore, a connecting rod hole is provided on the second hinge, and a second connecting rod is fixed on the connecting rod hole. The other end of the second connecting rod is fixed on the rotating shaft. The rotation of the second supporting foot drives the second hinge to rotate, so that the second guide shaft of the second folding frame moves into the limiting groove. By connecting the second connecting rod to the second hinge and the rotating shaft, the rotation of the second supporting foot is used to control the rotation of the second hinge, so that the second folding frame moves up and down, thereby completing the unlocking or locking of the second folding frame.

[0010] Furthermore, a rotating rod is connected between the rotating shafts on the two side plates, and the two ends and the middle of the rotating rod are bent to form a rigidity of the first folding frame or the second folding frame. At the same time, the rotating rod avoids the reinforcing tube on the folding frame to avoid interference.

[0011] Furthermore, a reinforcing rod mounting hole is opened in the center of the side panel, and a reinforcing rod is connected to the reinforcing rod mounting hole. The reinforcing rod connects the side panels on both sides, thereby enhancing the rigidity and strength between the side panels and preventing the side panels from shaking and affecting folding.

[0012] Furthermore, a universal wheel is installed at the lower end of the base frame, and the base frame is moved by the universal wheel, so that the folding bed is easy to move.

[0013] Furthermore, a pull rod is connected to the end surface of the first folding frame and the second folding frame close to the outer side, and the pull rod can be used to facilitate pulling the first folding frame and the second folding frame to rotate and fold.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) By forming an arc groove and a limit groove on the side plate, the arc groove is used to guide the folding of the first folding frame, and the limit groove limits the position of the first folding frame, so that the first folding frame is locked; (2) The first hinge and the rotating shaft are connected by a first connecting rod, and the rotation of the first hinge is controlled by the rotation of the first supporting foot, so as to drive the first folding frame to move up and down, and push the first guide shaft into the limiting groove, or push the first guide shaft out of the limiting groove. In this way, the first folding frame can be locked or unlocked by folding the first supporting foot, so that the first supporting foot and the folding of the folding bed are linked.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 , 3, 4 and 5, the present invention provides a technical solution: a guide rail folding bed, comprising a base frame 1, side panels 2 are fixed on both sides of the base frame 1, base frame mounting holes 23 are provided on the bottom of the side panels 2, the base frame mounting holes 23 are used to install the base frame 1, a first folding frame 4 is rotatably connected between the side panels 2 through a rotating shaft 6, a rotating shaft mounting hole 22 is provided on the side panels 2, which is used to rotatably connect the rotating shaft 6 so that the rotating shaft 6 rotates in the rotating shaft mounting hole 22, the first folding frame 4 is rotatably connected to the rotating shaft 6, and the first folding frame The first guide shaft 41 is fixed to both sides of one end of the side plate 4. Two symmetrically distributed guide grooves 21 are provided on the inner wall of the side plate 2. The first guide shaft 41 moves in the guide groove 21. The guide groove 21 includes an arc groove 211 and a limit groove 212. The first guide shaft 41 moves in the arc groove 211 to rotate the first folding frame 4. When the first guide shaft 41 moves to the end of the arc groove 211 and is located at the upper end of the limit groove 212, the first folding frame 4 is in a vertical folding state. When the first guide shaft 41 moves into the limiting groove 212, the first guide shaft 41 will be restricted by the two sides of the limiting groove 212, so that the first guide shaft 41 can only move up and down, locking the left and right directions of the first folding frame 4 to prevent the first folding frame 4 from rotating. A waist hole 42 is opened on the side of the first folding frame 4, and the rotating shaft 6 is connected to the waist hole 42. When the first folding frame 4 is rotated to a vertical state, the first folding frame 4 moves up and down to move the first guide shaft 41 into the limiting groove 212, and the first folding frame 4 is locked to achieve locking of the first folding frame 4. When the first guide shaft 41 moves into the arc groove 211, the first folding frame 4 can swing along the arc groove 211. When the first guide shaft 41 moves to the upper end of the arc groove 211, the first folding frame 4 is in a horizontal state. In summary, the arc groove 211 and the limiting groove 212 are used to limit the swing position of the first folding frame 4 to achieve folding locking of the first folding frame 4.

[0018] like Figure 2 As shown, the first folding frame 4 is connected to a first hinge 43 via a pin shaft, and a first supporting foot 44 is fixed to the lower end of the first hinge 43. By setting the first supporting foot 44, the first supporting foot 44 can support the first folding frame 4. At the same time, the rotation of the first hinge 43 can drive the first supporting foot 44 to rotate, so that the first supporting foot 44 can be folded or unfolded, which is convenient for storage and reduces the occupied space.

[0019] The first hinge 43 is provided with a connecting rod hole, and the connecting rod hole is connected with a first connecting rod 45 via a fastener. The other end of the first connecting rod 45 is fixed on the rotating shaft 6. The rotation of the first supporting foot 44 drives the first hinge 43 to rotate, and the two ends of the first connecting rod 45 are fixed on the rotating shaft 6 and the first hinge 43, and the length of the first connecting rod 45 is fixed, so that the rotation of the first supporting foot 44 and the first hinge 43 cannot move the first connecting rod 45. In this way, the rotation of the first hinge 43 can only rotate around the fastener at the upper end of the first connecting rod 45, driving the first folding frame 4 to move downward or upward, so that the first guide shaft 41 of the first folding frame 4 moves into the limiting groove 212 to lock the first folding frame 4, or the first guide shaft 41 is pushed into the arc groove 211 to unlock the first folding frame 4, so as to facilitate the rotation of the angle of the first folding frame 4.

[0020] like Figure 4 As shown, a second folding frame 5 is rotatably connected between the two side panels 2 via a rotating shaft 6. The second folding frame 5 and the first folding frame 4 are of a linearly symmetrical structure. A second guide shaft 51 is fixed to the side surface of one end of the second folding frame 5. The second guide shaft 51 also moves in the guide groove 21. By utilizing the cooperation between the second guide shaft 51 and the guide groove 21, the second folding frame 5 can also rotate along the guide groove to realize the folding or unfolding of the second folding frame 5.

[0021] The second folding frame 5 is also connected to a second hinge 53 via a pin shaft, and a second supporting foot 54 is also fixed to the lower end of the second hinge 53. The second folding frame 5 is supported by the second supporting foot 54, and the second supporting foot 54 can also be folded or unfolded by rotating the second hinge 53, so that the second supporting foot 54 can be stored conveniently and the occupied space can be reduced.

[0022] The second hinge 53 is provided with a connecting rod hole, and a second connecting rod 55 is fixed on the connecting rod hole. The other end of the second connecting rod 55 is fixed on the rotating shaft 6. The rotation of the second supporting foot 54 drives the second hinge 53 to rotate, so that the second guide shaft 51 of the second folding frame 5 moves into the limiting groove 212. The function of the second connecting rod 55 is similar to that of the first connecting rod 45. It is used to control the rotation of the second supporting foot 54 to lock or unlock the second folding frame 5 when the second folding frame 5 is in a folded state, and the arc groove 211 can also limit the second guide shaft 51, so that when the second folding frame 5 is in the unfolded state, the second supporting foot 54 cannot rotate, thereby ensuring the supporting force for the second folding frame 5 when it is unfolded.

[0023] A rotating rod 61 is connected between the rotating shafts 6. The two ends and the middle of the rotating rod 61 are bent and formed. The rotating rod 61 enhances the rigidity of the first folding frame 4 or the second folding frame 5. At the same time, the bent rotating rod 61 can make way for the reinforcing tube on the folding frame to avoid interference between the rotating rod 61 and the reinforcing tube.

[0024] A reinforcing rod mounting hole 24 is also provided in the center of the side panel 2 , and a reinforcing rod 11 is connected in the reinforcing rod mounting hole 24 . The reinforcing rod 11 connects the side panels 2 on both sides, and the connection strength and rigidity between the side panels 2 are enhanced through the reinforcing rod 11 .

[0025] Universal wheels 3 are installed at the lower end of the base frame 1, and the base frame 1 is convenient to move through the universal wheels 3, so that the folding bed that has been folded can be moved.

[0026] The first folding frame 4 and the second folding frame 5 are connected to the end surfaces close to the outer sides thereof with a pull rod 7 , and the first folding frame 4 and the second folding frame 5 can be conveniently rotated along the guide groove 21 through the pull rod 7 .

[0027] Folding locking process: Folding of the first folding frame: rotate the first guide shaft on the unfolded first folding frame along the arc groove, move the first guide shaft to the lower end of the arc groove and the upper end of the limit groove, then the first folding frame is in a vertical state, because the first supporting foot is in an open state, under the support of the first hinge and the first connecting rod, the first guide shaft is located at the upper end of the limit groove, then the first supporting foot is rotated to fold the first supporting foot, and the first hinge is rotated to lower the height of the first folding frame, so that the upper end of the waist hole moves to the rotating shaft, and at the same time the first guide shaft moves into the limit groove to lock the left and right directions of the first folding frame; Unlocking the first folding frame: by opening the first supporting foot, the first hinge rotates, while the length position of the connecting rod remains unchanged, which is equivalent to the first hinge rotating around the pin shaft or fastener at the end of the connecting rod, driving the first folding frame to move upward, and lifting the first guide shaft to the upper end of the limiting groove and on one side of the arc groove, thereby unlocking the first folding frame and allowing the first folding frame to rotate and unfold again.

[0028] Since the structure of the second folding frame is symmetrical to that of the first folding frame, the locking and unlocking process of the second folding frame is the same as that of the first folding frame, and a repeated description thereof will not be given here.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
