Description

Technical Field

[0001] The utility model relates to the technical field of folding beds, in particular to a conveniently movable and tiltable bed. Background Art

[0002] As people's quality of life improves, they increasingly value the importance of sleep. Electric beds are becoming increasingly popular over traditional beds. Electric beds can adjust the body's posture, allowing users to sit up or sit down without having to get up. Typically, electric beds consist of multiple hinged panels. A motor mounted on the bed frame, via a hinged drive rod, pushes a panel up or down at the hinge point, raising or lowering the head, hips, or feet, respectively, to accommodate the user's changing posture in bed.

[0003] For example, patent CN221229057U discloses a storage bed with an electrically powered mechanically raised bed panel. A lifting mechanism is connected between the bed frame and the bed panel frame, enabling the entire bed panel frame to be raised and lowered. However, this storage bed structure only raises and lowers the fixed bed frame, while the panel frame remains stationary. This results in insufficient stability during the raising and lowering process. Other existing technologies also utilize a structure in which the fixed bed frame is connected to the panel frame. However, these existing structures are complex, inconvenient to install, and costly.

[0004] In addition, the storage bed of the prior art also has the problem of being difficult to move. After the bed body is assembled, it is inconvenient to move the entire bed, and it requires the joint efforts of multiple people to carry it. Utility Model Content

[0005] In order to overcome at least one defect in the above-mentioned prior art, the present invention provides a conveniently movable and tiltable lift bed. The connection structure between the bed frame and the enclosure frame is simple and easy to install, and the strength of the connection structure is guaranteed. In addition, the entire lift bed can be easily moved when in the storage state.

[0006] The utility model provides a conveniently movable tiltable bed, comprising a fixed bed frame, an enclosure frame, and a support frame, wherein the fixed bed frame is fixed to the inner wall of the enclosure frame, and the lower ends of the four corners of the fixed bed frame are connected to rollers, and an adjustment mechanism for driving the fixed bed frame to switch between a first position and a second position is connected between the fixed bed frame and the support frame. In the first position, the support frame is stored in the enclosure frame, and the lower end surface of the roller exceeds the lower end surface of the enclosure frame. In the second position, the fixed bed frame is raised to a set height, and the support frame is fixedly supported on the ground.

[0007] The fixed bed frame includes two parallel cross beams, and a plurality of longitudinal beams are connected between the two cross beams. Below both ends of the two cross beams, first fixed beams are connected to connect both ends in the length direction of the fixed bed frame to the inner wall of the enclosure frame; below the middle positions of the two cross beams, reinforcing cross bars are connected, and both ends of the two reinforcing cross bars are connected with second fixed beams to connect both ends in the width direction of the fixed bed frame to the inner wall of the enclosure frame.

[0008] Compared with the prior art, the convenient movable and tiltable lift bed of the present utility model has the following advantages:

[0009] In the lift bed structure of the present utility model, the lifting adjustment between the fixed bed frame and the support frame can be realized through the adjustment mechanism, so as to realize the switching of two different states of the entire lift bed. That is, the fixed bed frame can be lifted to a set height for use, and during use, it is fixed to the ground through the support frame. When it is necessary to move the position of the bed body or when it is not needed, the support frame part can be received and accommodated in the enclosure frame to reduce the occupied volume. More importantly, in this received state, the roller part at the lower end of the fixed bed frame is higher than the lower end surface of the enclosure frame, so that the entire bed body can be easily moved by the rollers, and one person can complete it, which is very convenient; on the other hand, in the structure of the present utility model, the fixed bed frame is connected to the enclosure frame in the length direction through the first fixed beam, and is connected to the enclosure frame in the width direction through the reinforcing cross beam and the second fixed beam. The structure is simple, the installation is convenient, and the structural strength is high.

[0010] Further, the adjustment mechanism includes a first lifting component and a second lifting component. Both sides of the upper end of the first lifting component are respectively hinged to the two first fixed beams at one end of the fixed bed frame, and both sides of the lower end are respectively slidably connected to one end of the support frame; both sides of the upper end of the second lifting component are respectively hinged to the two first fixed beams at the other end of the fixed bed frame, and both sides of the lower end are respectively rotatably connected to the other end of the support frame.

[0011] Still further, the first lifting component and the second lifting component have the same structure, and both include a first adjustment frame and a second adjustment frame. Roller shafts are respectively rotatably connected to both sides of the upper end of the first adjustment frame, and both sides of the lower end are respectively rotatably connected or slidably connected to the corresponding support frame. Both sides of the lower end of the second adjustment frame are respectively hinged to both sides of the middle position of the first adjustment frame, and both sides of the upper end are respectively hinged to the corresponding first fixed beam; the roller shafts at the upper ends of the first adjustment frames are respectively slidably connected to the side walls of the reinforcing cross bars.

[0012] As an improvement, both of the two reinforcing cross bars are U-shaped channel steels, and the openings of the two U-shaped channel steels are arranged oppositely along the horizontal direction. Both sides of the upper ends of the two first adjusting frames are respectively slidably fitted in the grooves of the two U-shaped channel steels through roller shafts.

[0013] As a further improvement, two electric push rods are rotatably connected to the longitudinal beam at the middle position of the fixed bed frame, and the driving ends of the two electric push rods are respectively hinged to the lower ends of the two second adjusting frames.

[0014] As a further improvement, the support frame includes a rectangular frame. U-shaped slide rails with openings facing inwards horizontally are respectively connected to both side walls at one end in the length direction of the rectangular frame. Both sides of the lower end of one of the first adjusting frames are respectively slidably fitted in the two U-shaped slide rails through roller shafts; Hinge seats are respectively connected to both side walls at the other end in the length direction of the rectangular frame, and both sides of the lower end of the other first adjusting frame are respectively rotatably connected to the two hinge seats; Fixed bed feet are connected to the lower ends at the four corner positions of the rectangular frame.

[0015] As a further improvement, positioning columns are connected to the lower ends of the four first fixed beams at both ends of the fixed bed frame.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 4As shown in the figure, an embodiment of the present application discloses a conveniently movable and tiltable lift bed, which includes a fixed bed frame 1, a guardrail frame 2, and two support frames 3. The guardrail frame 2 is a rectangular structure surrounded by two long side plates and two short side plates. The fixed bed frame 1 is connected inside the guardrail frame 2. Specifically, the two ends of the fixed bed frame 1 in the length direction and width direction are respectively connected to the inner walls of the guardrail frame 2 through a first fixing frame and a second fixing frame. The fixed bed frame 1 includes two parallel cross beams 5, and multiple longitudinal beams 6 are connected between the two cross beams 5. The multiple longitudinal beams 6 are all perpendicular to the two cross beams 5. Preferably, there are five longitudinal beams 6, two of which are respectively located between the two ends of the two cross beams 5, and the other three are located between the middle positions of the two cross beams 5. And first fixing beams 7 are connected below the two ends of the two cross beams 5 to form a first fixing frame for connecting the two ends of the fixed bed frame 1 in the length direction to the inner wall of the guardrail frame 2. More specifically, the two first fixing beams 7 have the same structure as the cross beams 5 and longitudinal beams 6, which are all hollow square tube structures, and the first fixing beams 7 are parallel to the cross beams 5, and are connected and fixed to the inner side walls of the two short side plates through elements such as metal connecting pieces and screws at one end. Similarly, strengthening cross bars 8 are connected below the middle positions of the two cross beams 5, and second fixing beams 9 are connected to both ends of the two strengthening cross bars 8 to form a second fixing frame for connecting the two ends of the fixed bed frame 1 in the width direction to the inner wall of the guardrail frame. Here, the second fixing beam 9 is also a hollow square tube like the first fixing beam 7, and one ends of the four hollow square tubes are respectively connected and fixed to the inner side walls of the two long side plates through elements such as metal connecting pieces and screws to realize the connection and fixation of the fixed bed frame 1 and the guardrail frame 2, and corresponding fixing structures are provided in both the length and width directions, effectively improving the structural strength. In practical applications, multiple bed boards 17 are installed on the top of the fixed bed frame 1, and the bed boards 17 related to the human back and legs can also be set to an angle-adjustable structure. This structure is a prior art and will not be elaborated here.

[0028] In addition, in this embodiment, rollers 4 are connected to the lower ends of the four corners of the fixed bed frame 1, and an adjusting mechanism for driving the fixed bed frame 1 to switch between a first position and a second position is connected between the fixed bed frame 1 and the support frame 3. Specifically, in the first position, the support frame 3 moves closer to the fixed bed frame 1, that is, the support frame 3 is received in the guardrail frame 2, and at this position, the lower end surfaces of the four rollers 4 protrude beyond the lower end surface of the guardrail frame 2, and the entire bed body can be moved easily with a gentle push by hand, which is very convenient. In the second position, the fixed bed frame 1 is lifted to a set height in a direction away from the support frame 3. This height can be adjusted according to the actual needs of the user, and in this use position, the entire bed body is fixedly supported on the ground by the support frame 3.

[0029] In the structure of this embodiment, the adjusting mechanism includes a first lifting component and a second lifting component. The two sides of the upper end of the first lifting component are respectively hinged to two first fixed beams 7 at one end of the fixed bed frame 1, and the two sides of the lower end are respectively slidably connected to one end of the support frame 3; the two sides of the upper end of the second lifting component are respectively hinged to two first fixed beams 7 at the other end of the fixed bed frame 1, and the two sides of the lower end are respectively rotatably connected to the other end of the support frame 3.

[0030] More specifically, the first lifting component and the second lifting component have the same structure. They both include a first adjusting frame 10 and a second adjusting frame 11. The two sides of the upper end of the first adjusting frame 10 are both rotatably connected with roller shafts, and the two sides of the lower end are respectively rotatably connected or slidably connected to the corresponding support frame 3. The two sides of the lower end of the second adjusting frame 11 are respectively hinged to the two sides of the middle position of the first adjusting frame 10, and the two sides of the upper end are respectively hinged to the corresponding first fixed beams 7; the roller shafts at the upper ends of the two first adjusting frames 10 are respectively slidably connected to the side walls of the strengthening cross bar 8 in the left-right direction, so as to realize the folding or unfolding between the fixed bed frame 1 and the support frame 3.

[0031] In the above structure, preferably, the two strengthening cross bars 8 are both U-shaped channel steels, and the openings of the two U-shaped channel steels are arranged opposite to each other in the horizontal direction. The two sides of the upper ends of the two first adjusting frames 10 are respectively slidably fitted in the grooves of the two U-shaped channel steels through roller shafts. The grooves of the U-shaped channel steels are used for the sliding guidance of the roller shaft structure, ensuring that when the adjusting mechanism acts, the upper end of the first adjusting frame 10 can move smoothly on the strengthening cross bar 8, so as to ensure the smooth driving of the lifting of the fixed bed frame 1.

[0032] In addition, in this embodiment, the power sources of the first lifting component and the second lifting component are both electric push rods 12. Specifically, it means that two electric push rods 12 are rotatably connected to the longitudinal beam 6 at the middle position of the fixed bed frame 1, and the driving ends of the two electric push rods 12 are respectively hinged to the lower ends of the two second adjusting frames 11. By the telescoping of the two electric push rods 12, the relative rotation between the first adjusting frame 10 and the second adjusting frame 11 is realized, and then the automatic height adjustment of the corresponding end of the fixed bed frame 1 is realized. The structure is simple, the operation is convenient, and it can be completed with one key.

[0033] In this structure, when the two electric push rods 12 run synchronously, that is, the extending lengths of the extending rod parts of the two electric push rods 12 are the same, the entire fixed bed frame 1 lifts and lowers horizontally; when the two electric push rods 12 run asynchronously, that is, the extending lengths of the extending rod parts of the two electric push rods 12 are different, the fixed bed frame 1 will tilt, and the user can choose to tilt the head downward or the feet downward according to actual needs.

[0034] In this embodiment, the involved support frame 3 includes a rectangular frame. On both side walls at one end in the length direction of the rectangular frame, U-shaped sliding rails 13 with horizontally inward openings are respectively connected. On both sides at the lower end of the first adjustment frame 10 of the first lifting assembly, they are respectively in sliding fit within the two U-shaped sliding rails 13 through roller shafts; on both side walls at the other end in the length direction of the rectangular frame, hinge seats 14 are respectively connected; at both sides at the lower end of the first adjustment frame 10 of the second lifting assembly, they are respectively rotatably connected to the two hinge seats 14; at the lower ends of the four corner positions of the rectangular frame, fixed bed feet 16 are all connected. In this structure, for the two first adjustment frames 10, the lower end of one first adjustment frame 10 is hinged to the support frame 3, and the lower end of the other first adjustment frame 10 is slidably connected to the support frame 3 to leave a certain sliding distance to facilitate the relative lifting movement between the fixed support and the support frame 3. If the lower ends of both first adjustment frames 10 are hinged to the support frame 3, then during the lifting process, it will get stuck and unable to lift.

[0035] On the other hand, in the above structure, referring to the attached Figure 3 , at the lower ends of the four first fixed beams 7 at both ends of the fixed bed frame 1, positioning columns 15 are all connected. When the fixed bed frame 1 and the support frame 3 are brought closer and stored in the first position, the lower end faces of the four positioning columns 15 respectively abut against the upper end faces of the support frame 3 to improve the stability of the entire bed body in the stored state.

Moreover, the specific features, mechanisms, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
