Description

Technical Field

[0001] The present invention relates to the technical field of medical device equipment, and specifically relates to a flip - type accompanying bed. Background Art

[0002] The accompanying bed is a temporary rest device provided by the hospital for the family members of patients, aiming to provide a convenient and comfortable rest environment for the accompanying family members. The accompanying bed is divided into fixed - type, movable - type and intelligent - type, which have comfort and convenience, help to relieve the problem of tight ward beds, provide a convenient and comfortable environment, and at the same time reduce the risk of cross - infection.

[0003] There are some deficiencies in the accompanying beds in the prior art. The existing accompanying beds are complex in structure when folding or unfolding, inconvenient to store, and have a single function, unable to meet diverse nursing needs. When the accompanying personnel do not use the accompanying bed for rest, since the accompanying bed itself occupies a certain space, to a certain extent, it also reduces the utilization rate of the accompanying bed itself. For this reason, we propose a flip - type accompanying bed. Summary of the Invention

[0004] The purpose of the present invention is to provide a flip - type accompanying bed to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A flip - type accompanying bed, including a bed frame, a support frame fixedly connected to the bottom of the bed frame, and a flip - over assembly arranged inside the bed frame. The flip - over assembly includes a servo motor fixedly connected to the inner wall of the side of the support frame. The output end of the servo motor is fixedly connected with an output shaft. The outer wall of the other end of the output shaft is fixedly connected with a gear. The top of the gear is engaged with a toothed ring. The inner wall of the toothed ring is fixedly connected with a rotating block. The inner wall of the rotating block is fixedly connected with a rotating rod. The outer walls of both ends of the rotating rod are rotationally connected to the inner wall of the bed frame through bearings. The outer wall of the middle part of the rotating rod is fixedly connected with a bed board. The top of the bed board is fixedly connected with a sponge block. By setting the flip - over assembly, it is convenient for the accompanying personnel to flip the bed board so that the bottom of the bed board faces upward, realizing the transformation of the accompanying bed into a table, and items can be placed on the surface of the bed board, thereby improving the utilization rate of the accompanying bed.

[0006] Preferably, the flip assembly also includes a positioning groove provided on the inner wall of the side of the rotating block, the inner wall of the positioning groove is slidably connected with a positioning column, one end of the positioning column is fixedly connected with a pull plate, the side wall of the pull plate is fixedly connected with a spring, the other end of the spring is fixedly connected to the outer wall of the bed frame, the top of the pull plate is fixedly connected with a limiting block, the top inner wall of the limiting block is slidably connected with a limiting rod, the side wall of the limiting rod is fixedly connected with a connecting block, the end face of the connecting block is fixedly connected to the outer wall of the bed frame, when it is necessary to flip the bed board, the accompanying personnel pulls the pull plate to prompt the pull plate to pull the positioning column, so that the positioning column is separated from the limitation of the inner wall of the positioning groove and compresses the spring. When the bed board is flipped over, the accompanying personnel releases the pull plate, and under the reaction force of the spring, the pull plate is limited in cooperation with the limiting block and the limiting rod, which will prompt the positioning column to reset and make the positioning column embedded in the inner wall of the positioning groove, thereby realizing the limitation of the rotating block and improving the stability of the bed board after flipping.

[0007] Preferably, the inner wall of the support frame is provided with a moving assembly, and the moving assembly includes a transverse plate fixedly connected to the inner wall of the support frame, and the bottom inner wall of the transverse plate is fixedly connected to a double-headed motor, the output end of the double-headed motor is fixedly connected to a screw rod, the outer wall of the screw rod is threadedly connected to a sleeve block, the bottom of the sleeve block is movably connected to a rotating plate through a hinge, and the other end of the rotating plate is movably connected to a lifting plate through a hinge, and the bottom of the lifting plate is fixedly connected to a roller. By setting the moving assembly, when the accompanying personnel needs to transfer the position of the accompanying bed, by starting the double-headed motor, the double-headed motor will cause the screw rod to rotate after starting, and cause the sleeve block to move laterally along the outer wall of the screw rod. In the process of moving the sleeve block, the rotating plate will be caused to rotate under the action of the hinge, causing the lifting plate to move downward, and when the lifting plate moves downward, the roller at its bottom will fit into the ground. Subsequently, the accompanying personnel can transfer the accompanying bed by pushing the accompanying bed under the action of the rotation of the roller.

[0008] Preferably, a head of a bed is fixedly connected to the top of one side of the bed frame, a pillow is fixedly connected to the side wall of the head of the bed, and a foot of a bed is fixedly connected to the top of the other side of the bed frame.

[0009] Preferably, a guardrail is fixedly connected to the outer wall of the bed frame, there are two guardrails, the two guardrails are equal in size, and the two guardrails are symmetrically distributed along the center plane of the bed frame. By providing two guardrails, it is convenient to use the guardrails on both sides of the bed frame to achieve shielding and protection for the accompanying personnel who are resting.

[0010] Preferably, the top of the bed board is fixedly connected to the bottom of the sponge block, and the bottom of the bed board is a smooth plane. By setting the bottom of the bed board as a smooth plane, it is convenient for the accompanying personnel to place items on the smooth side of the bed board after turning the bed board over, thereby improving the utilization rate of the accompanying bed.

[0011] Preferably, there are four positioning grooves, which are of equal size and are distributed in a circular array on the side of the rotating block along the central axis of the rotating block. The inner wall of the positioning groove is matched with the outer wall of one end of the positioning column. By opening the positioning groove on the side wall of the rotating block, it is convenient to embed the positioning column into the inner wall of the positioning groove, thereby realizing the limiting of the rotating block.

[0012] Preferably, there are four rollers, which are equal in size and fixedly connected to the four corners of the bottom of the lifting plate at equal distances. By arranging four rollers at the bottom of the lifting plate, it is convenient for the accompanying personnel to transfer the accompanying bed.

[0013] The present invention provides a reversible accompanying bed, which has the following beneficial effects: (1) The flippable accompanying bed is provided with a flipping assembly. When the accompanying staff is accompanying the patient and has finished resting on the accompanying bed, in order to improve the utilization rate of the accompanying bed, the bed board can be flipped so that the bottom of the bed board faces upwards, and the bed board is flipped into a table for the accompanying staff to place items. At this time, the operator starts the servo motor to cause the output shaft to rotate. During the rotation of the output shaft, the gear will rotate. During the rotation of the gear, it will mesh with the gear ring, causing the rotating block to rotate. During the rotation of the rotating block, the rotating rod will rotate, thereby causing the bed board to rotate. Under the operation of the servo motor, the bed board will rotate 180 degrees. The bottom of the bed board is turned upward, and the sponge block is turned downward, so that the accompanying bed can be transformed into a table when the accompanying person is not resting, and items can be placed on the top surface of the bed board, thereby improving the utilization rate of the accompanying bed. When the bed board needs to be turned over, the accompanying person pulls the pull plate to prompt the pull plate to pull the positioning column, so that the positioning column is separated from the limit of the inner wall of the positioning groove and compresses the spring. When the bed board is turned over, the accompanying person releases the pull plate, and under the reaction force of the spring, the pull plate is limited by the limit block and the limit rod, which prompts the positioning column to reset and embed the positioning column into the inner wall of the positioning groove, thereby realizing the limitation of the rotating block and improving the stability of the bed board after turning over. (2)When the caregiver needs to move the position of the foldable nursing bed, by setting up the moving component, start the dual-head motor. After the dual-head motor starts, it will cause the lead screw to rotate, and cause the socket block to move horizontally along the outer wall of the lead screw. During the movement of the socket block, under the action of the hinge, it will cause the rotating plate to rotate, and cause the lifting plate to move downward. When the lifting plate moves downward, the rollers at its bottom will be in contact with the ground. Subsequently, the caregiver can push the nursing bed, and under the action of the rotating rollers, the nursing bed can be moved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0016] In order to understand the technical features, objectives and effects of the present invention more clearly, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0017] A preferred embodiment of the foldable nursing bed provided by the present invention is as Figures 1 to 7As shown: A flip - type escort bed, including a bed frame 1, a support frame 2 fixedly connected to the bottom of the bed frame 1, and a flip - over assembly 31 arranged inside the bed frame 1. The flip - over assembly 31 includes a servo motor 311 fixedly connected to the inner wall of the side of the support frame 2. The output end of the servo motor 311 is fixedly connected with an output shaft 312. The outer wall of the other end of the output shaft 312 is fixedly connected with a gear 313. A toothed ring 314 is meshed with the top of the gear 313. The inner wall of the toothed ring 314 is fixedly connected with a rotating block 315. The inner wall of the rotating block 315 is fixedly connected with a rotating rod 317. The outer walls of both ends of the rotating rod 317 are rotationally connected to the inner wall of the bed frame 1 through bearings. The outer wall of the middle part of the rotating rod 317 is fixedly connected with a bed board 318. The top of the bed board 318 is fixedly connected with a sponge block 319. By setting the flip - over assembly 31, when the escort is accompanying the patient and after finishing resting on the escort bed, in order to improve the utilization rate of the escort bed, the bed board 318 can be flipped so that the bottom of the bed board 318 faces upward, turning the bed board 318 into a table, which is convenient for the escort to place items. At this time, the operator starts the servo motor 311, causing the output shaft 312 to rotate. During the rotation of the output shaft 312, the gear 313 will be driven to rotate. During the rotation of the gear 313, it will mesh with the toothed ring 314, causing the rotating block 315 to rotate. During the rotation of the rotating block 315, the rotating rod 317 will be driven to rotate, thereby driving the bed board 318 to rotate. Under the operation of the servo motor 311, the bed board 318 will rotate 180 degrees, achieving the purpose that the bottom of the bed board 318 faces upward and the sponge block 319 rotates downward. When the escort is not resting, it is convenient to turn the escort bed into a table and place items on the top surface of the bed board 318, improving the utilization rate of the escort bed.

[0018] The flipping component 31 further includes a positioning groove 316 formed in the inner wall of the side surface of the rotating block 315. A positioning post 3110 is slidably connected to the inner wall of the positioning groove 316. One end of the positioning post 3110 is fixedly connected to a pulling plate 3111. A spring 3112 is fixedly connected to the side wall of the pulling plate 3111. The other end of the spring 3112 is fixedly connected to the outer wall of the bed frame 1.

The other end of the rotating plate 325 is movably connected to a lifting plate 326 through a hinge. A roller 327 is fixedly connected to the bottom of the lifting plate 326. By providing the moving component 32, when the caregiver needs to transfer the position of the nursing bed, by starting the double-headed motor 322, after the double-headed motor 322 is started, the lead screw 323 will be driven to rotate, and the socket block 324 will be caused to move horizontally along the outer wall of the lead screw 323. During the movement of the socket block 324, under the action of the hinge, the rotating plate 325 will be caused to rotate, and the lifting plate 326 will be caused to move downward. After the lifting plate 326 moves downward, the roller 327 at its bottom will be in contact with the ground. Subsequently, the caregiver pushes the nursing bed, and under the action of the rotation of the roller 327, the nursing bed can be transferred.

[0020] Furthermore, a headboard 5 is fixedly connected to the top of one side of the bed frame 1, a pillow 6 is fixedly connected to the side wall of the headboard 5, and a footboard 7 is fixedly connected to the top of the other side of the bed frame 1.

[0021] Furthermore, a guardrail 4 is fixedly connected to the outer wall of the bed frame 1. There are two guardrails 4, and the two guardrails 4 are of equal size. The two guardrails 4 are symmetrically distributed along the central plane of the bed frame 1. By providing the two guardrails 4, it is convenient to shield and protect the accompanying personnel during rest through the guardrails 4 on both sides of the bed frame 1.

[0022] Furthermore, the top of the bed board 318 is fixedly connected to the bottom of the sponge block 319. The bottom of the bed board 318 is a smooth plane. By setting the bottom of the bed board 318 as a smooth plane, it is convenient for the accompanying personnel to place items on the smooth side of the bed board 318 after flipping the bed board 318, improving the utilization rate of the accompanying bed.

[0023] Furthermore, there are four positioning grooves 316. The four positioning grooves 316 are of equal size. The four positioning grooves 316 are circumferentially arranged along the central axis of the rotating block 315 on its side. The inner wall of the positioning groove 316 is adapted to the outer wall of one end of the positioning column 3110. By providing the positioning grooves 316 on the side wall of the rotating block 315, it is convenient to limit the rotating block 315 after the positioning column 3110 is inserted into the inner wall of the positioning groove 316.

[0024] In addition, there are four rollers 327. The four rollers 327 are of equal size. The four rollers 327 are equidistantly and fixedly connected to the four corners of the bottom of the lifting plate 326. By providing the four rollers 327 at the bottom of the lifting plate 326, it is convenient for the accompanying personnel to transfer the accompanying bed.

[0025] Working principle: When the accompanying personnel are accompanying the patient and finish resting on the accompanying bed, in order to improve the utilization rate of the accompanying bed, the bed board 318 can be flipped so that the bottom of the bed board 318 faces upward, turning the bed board 318 into a table for the accompanying personnel to place items. At this time, the operator starts the servo motor 311, causing the output shaft 312 to rotate. During the rotation of the output shaft 312, the gear 313 will rotate. During the rotation of the gear 313, it will engage with the toothed ring 314, causing the rotating block 315 to rotate. During the rotation of the rotating block 315, the rotating rod 317 will be driven to rotate, thereby driving the bed board 318 to rotate. Under the operation of the servo motor 311, the bed board 318 will be rotated 180 degrees, achieving the purpose of the bottom of the bed board 318 facing upward, making the sponge block 319 rotate downward. When the accompanying personnel are not resting, the accompanying bed can be turned into a table and items can be placed on the top surface of the bed board 318, improving the utilization rate of the accompanying bed; When it is necessary to flip the bed board 318, the accompanying personnel pull the pull board 3111, which causes the pull board 3111 to pull the positioning column 3110, so that the positioning column 3110 disengages from the inner wall of the positioning groove 316 and compresses the spring 3112. After the flipping of the bed board 318 is completed, the accompanying personnel release the pull board 3111. Under the reaction force of the spring 3112 and with the cooperation of the limit block 3113 and the limit rod 3114 to limit the pull board 3111, the positioning column 3110 will be reset, and the positioning column 3110 will be embedded in the inner wall of the positioning groove 316, thereby realizing the limitation of the rotating block 315 and improving the stability of the bed board 318 after flipping. When the accompanying personnel need to transfer the position of the accompanying bed, they start the double-headed motor 322. After the double-headed motor 322 is started, it will cause the lead screw 323 to rotate, and cause the socket block 324 to move horizontally along the outer wall of the lead screw 323. During the movement of the socket block 324, under the action of the hinge, the rotating plate 325 will be caused to rotate, and the lifting plate 326 will move downward. After the lifting plate 326 moves downward, the rollers 327 at its bottom will be in contact with the ground. Subsequently, the accompanying personnel push the accompanying bed, and under the action of the rotation of the rollers 327, the accompanying bed can be transferred.
