Description

Technical Field

[0001] The utility model relates to the technical field of nursing beds, in particular to a nursing bed with a movable armrest frame. Background Art

[0002] Nursing beds are very convenient to use in nursing care institutions and home care. In the prior art, nursing beds are widely used in nursing homes and hospitals. Generally, nursing beds need to be equipped with armrests. The functions of the nursing bed armrests are to maintain body balance or support the patient's body on the one hand, and to prevent the user from falling from the bed and causing injury on the other hand. The existing nursing bed armrests include fixed armrests and folding flat armrests. The folding flat armrests are provided with a button on the side close to the patient's head. When folding is required, the armrest can be folded and placed on the edge of the nursing bed by pressing the button. Both existing nursing bed armrests only provide a supporting force to the patient in the vertical direction. When the patient lies down and needs to get up, it is impossible to apply force in the vertical direction. Therefore, when the patient gets up, the nursing bed armrests are difficult to provide help; in addition, when the existing nursing bed armrests are fully supported, it will affect the action interaction between the nursing staff and the patient, such as it is very inconvenient to hand things to the patient.

[0003] In order to solve the above problems, a patent such as patent publication number CN207236935U discloses a nursing bed armrest, which includes a first horizontal rod connected to the bed body and a second horizontal rod arranged parallel to the first horizontal rod, and a plurality of vertical brackets arranged perpendicularly thereto are hingedly provided between the first and second horizontal rods; an armrest is hingedly provided at one end of the first horizontal rod, and the armrest includes a support frame and a protection frame, and the support frame and the protection frame are connected by a hinge.

[0026] Example

[0027] Please refer to Figure 1-Figure 4 , Figure 1 Shown is a three-dimensional outline diagram of an embodiment of the utility model; Figure 2 It is a schematic diagram of the cross-sectional structure of an embodiment of the utility model; Figure 3 for Figure 2 The enlarged view of point A in the middle; Figure 4 The three-dimensional structure diagram of the bed board in the embodiment of the utility model. The embodiment provides a nursing bed with a movable armrest frame, including a bed board 1 and an armrest assembly. The bed board 1 is the main component of the nursing bed, and the patient can lie on the bed board 1. The armrest assembly is used to act as an armrest and can also block the patient.

[0028] The armrest assembly includes two armrest rods 2 symmetrically arranged on both sides of the bed board 1, any of the armrest rods 2 is located above the bed board 1, and a height adjustment assembly is arranged between any of the armrest rods 2 and the bed board 1. The height adjustment assembly includes a lifting rod 3, a guide rod 4 and a lifting mechanism. Two mutually parallel guide holes 5 are symmetrically provided on one side of the bed board 1, and the lifting rod 3 and the guide rod 4 respectively pass through the two guide holes 5. Both the lifting rod 3 and the guide rod 4 can move along the axial direction of the guide hole 5. The lifting mechanism is arranged on the bed board 1, and the lifting end of the lifting mechanism is connected to the lifting rod 3, which is used to drive the lifting rod 3 to move along the axial direction. One end of the armrest rod 2 is connected to the guide rod 4, and the other end is connected to the lifting rod 3.

[0029] The two handrails 2 are respectively arranged on both sides of the bed board 1 to block the two sides of the bed board 1. The height adjustment assembly arranged between the handrail 2 and the bed board 1 is used to adjust the height between the handrail 2 and the bed board 1. Specifically, the lifting rod 3 and the guide rod 4 cooperate to drive the handrail 2 to rise and fall, so that the height of the handrail 2 can be adjusted. At the same time, the guide rod 4 and the lifting rod 3 will not occupy the space above the bed board 1 during the lifting and lowering process of the corresponding guide hole 5. The lifting mechanism is used to drive the lifting rod 3 to rise and fall.

[0030] Therefore, the nursing bed with a movable armrest frame can adjust the height of the armrest bar 2, so that the patient can adjust it to the required height conveniently and quickly according to his own needs.

[0031] In some implementations of the present embodiment, the lifting mechanism includes a worm wheel 6 and a worm 7, an annular cavity 8 is opened on the side wall of the guide hole 5 located at the lifting rod 3, the worm wheel 6 is rotatably arranged in the annular cavity 8, the lifting rod 3 is passed through the worm wheel 6 and is threadedly connected to the worm wheel 6, the lifting rod 3 is threadedly connected to the bed board 1, one end of the worm 7 extends into the annular cavity 8 and engages with the worm 7, the worm 7 is rotatably arranged on the bed board 1, and one end of the worm 7 away from the worm wheel 6 extends out of the bed board 1.

[0032] In this embodiment, the worm wheel 6, worm 7 and lifting rod 3 can cooperate with the bed body to form a worm wheel 6 and worm 7 lifting structure. Specifically, the worm wheel 6 can be driven to rotate by rotating the worm 7 located outside the bed board 1. At this time, since the worm wheel 6 is threadedly connected to the lifting rod 3, and the lifting rod 3 is threadedly connected to the bed board 1, the rotation of the worm wheel 6 will convert its selected motion into a linear motion of the lifting rod 3 in the axial direction. In this way, the lifting rod 3 can drive the handrail rod 2 to rise and fall, thereby adjusting the height of the handrail rod 2. After the lifting rod 3 is lifted, the lifting structure of the worm wheel 6 and worm 7 will automatically be locked so that the lifting rod 3 will not continue to rise and fall, so that the handrail can be stably fixed at the required height. The annular cavity 8 is used to facilitate the installation of the worm wheel 6, and the annular cavity 8 is actually opened on the side wall of the corresponding guide hole 5.

[0033] In some implementations of this embodiment, one end of the worm 7 extending out of the bed board 1 is connected to a driving hand wheel 10. The driving hand wheel 10 is used to conveniently control the worm 7 to rotate to a desired position, thereby accurately controlling the handrail 2 on the lifting rod 3 to adjust to a desired height.

[0034] In some implementations of this embodiment, the worm wheel 6 is rotatably disposed in the annular cavity 8 via a bearing 9. The bearing 9 is used to mount the worm wheel 6 so that the worm wheel 6 can be rotatably disposed in the annular cavity 8.

[0035] In some implementations of this embodiment, a strip groove 11 matching the handrail 2 is provided on the bed board 1, and the handrail 2 can be embedded in the strip groove 11. In this embodiment, the strip groove 11 can be embedded in the handrail 2, so that the handrail can better fit the bed board 1 and avoid the problem of blocking the patient after the handrail is lowered to the lowest position.

[0036] In some implementations of this embodiment, a limiting rod 12 is arranged under the bed board 1, one end of the limiting rod 12 is connected to the free end of the lifting rod 3, and the other end is connected to the free end of the guide rod 4, and the limiting rod 12 is parallel to the handrail rod 2.

[0037] In this embodiment, the limiting rod 12 can play a limiting role, so that after the limiting rod 12 abuts against the bed board 1, the worm 7 can no longer rotate, so that the lifting rod 3 can be prevented from slipping out after being separated from the worm wheel 6.

[0038] In some implementations of this embodiment, a plurality of railings 13 are evenly spaced between the handrail 2 and the limit rod 12, one end of any of the railings 13 is vertically connected to the handrail 2, and the other end passes through the bed board 1 and is connected to the limit rod 12, and the railing 13 can slide freely along the axial direction on the bed board 1. In this embodiment, the railing 13 can play a further blocking effect. The railing 13 can slide freely along the axial direction on the bed board 1, so that its function is the same as that of the guide rod 4, and it plays a guiding effect, and it will not cause obstruction when adjusting the handrail 2.

[0039] In some implementations of this embodiment, a height indicator line 14 is engraved on the guide rod 4. The height indicator line 14 can indicate the height of the handrail at that time.

[0040] When in use, two handrails 2 are respectively arranged on both sides of the bed board 1 to block the two sides of the bed board 1. The height adjustment assembly arranged between the handrail 2 and the bed board 1 is used to adjust the height between the handrail 2 and the bed board 1. Specifically, the lifting rod 3 and the guide rod 4 cooperate to drive the handrail 2 to rise and fall, so that the height of the handrail 2 can be adjusted. At the same time, the guide rod 4 and the lifting rod 3 will not occupy the space above the bed board 1 during the lifting and lowering process of the corresponding guide hole 5. The lifting mechanism is used to drive the lifting rod 3 to rise and fall.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. 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.
