[0029] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] A safe transport bed for emergency use according to a preferred embodiment of the present invention will be described in detail below.

[0031] like Figure 1-Figure 8 As shown, a safe transport bed for emergency use comprises a moving seat 1, a lifting frame 11 is arranged above the moving seat 1, a bed board 2 is movably hinged on the top of the lifting frame 11, a groove is provided in the middle of the bed board 2, a first enclosure 21 is fixedly installed on the right side of the groove, and a second enclosure 22 is slidably inserted on the left side of the groove;

[0032] Hollow bearing bars 5 are slidably connected on both sides of the groove, and the bearing bar 5 can be moved out from the left side of the bed board 2. A bevel gear roller 54 is rotatably connected between the bearing bars 5 on both sides, and a bevel gear roller 2 57 is movably arranged between the bearing bars 5 on both sides, and the bevel gear roller 2 57 is located on the left side of the bevel gear roller 1 54. A conveyor belt 58 is fixedly connected between the bevel gear roller 1 54 and the bevel gear roller 2 57, and the conveyor belt 58 is wound around the bevel gear roller 1 54 for multiple turns. An adjusting component is arranged at the bottom of the bed board 2, and the adjusting component is used to adjust the upper and lower positions of the enclosure 2 22 and to adjust the extension state of the bearing bar 5. A driving component is movably arranged between the bearing bars 5 on both sides, and a tooth groove 510 is opened on the inner wall of the bearing bar 5, and a tooth segment is provided on the upper wall of the tooth groove 510. A gear ring 59 is fixedly sleeved on both sides of the bevel gear roller 2 57, and the gear ring 59 is meshed with the tooth segment.

[0033] A transfer box 7 is fixedly connected to the front end of the bed board 2, and a cover plate 71 is slidably connected to the top of the transfer box 7. A horizontal telescopic bracket 8 is rotatably connected to the right wall of the bed board 2, and a fixing bolt 81 is threadedly inserted into the side wall of the telescopic bracket 8. A card slot 1 82 and a card slot 2 83 are respectively opened on the right wall of the bed board 2.

[0034] When in use, the transfer bed can protect the patient on both sides by the enclosure 1 21 and the enclosure 2 22 to prevent falling. When transferring, after the transfer bed is close to the bed, the lifting frame 11 is controlled to drive the bed board 2 to move up, so that the conveyor belt 58 is just higher than the bed surface. In the initial state, there is a gap between the conveyor belt 58 on the surface of the bevel roller 2 57 and the enclosure 2 22. The control adjustment component is operated to drive the bearing bars 5 on both sides to extend to the left, and the adjustment component drives the elastic bar 23 to make the enclosure 2 22 move down quickly. Compared with the prior art, there is no need for manual adjustment, and it can automatically and timely avoid the conveyor belt 58, which is safe and reliable to use. Subsequently, the bearing bar 5 extends to the left to drive the conveyor belt 58 to carry the patient to the bed. When the patient is above the bed, the driving assembly is controlled to operate, and the bevel roller 1 54 and the bevel roller 2 57 rotate counterclockwise synchronously, and the conveyor belt 58 is immediately driven to rotate counterclockwise, and the conveyor belt 58 transports the patient to the bed. Synchronously, under the action of the meshing tooth segment of the gear ring 59, the bevel roller 1 54 winds up the conveyor belt 58 and moves to the right, so as to automatically and stably place the patient on the bed, thereby improving the convenience and reliability of patient transportation. At the same time, according to the needs of the disease, the transfer box 7 can be used to properly store or carry first aid items, medicines or first aid instruments, etc., to prevent the transported items from being pressed on the patient's limbs or quilt, and in conjunction with the telescopic bracket 8, it is convenient for infusion at any time to ensure the continuity of first aid and medication.

[0035] In this embodiment, the adjustment component includes an elastic strip 23 fixedly connected to the bottom of the enclosure 22, a slide groove 24 is opened in the middle of the elastic strip 23, a crank 3 is rotatably connected to the left wall of the bottom of the bed board 2, and a slide column 31 is fixedly connected to the end of the crank 3 away from its own axis. The slide column 31 is movably engaged with the slide groove 24, and an arc groove 32 is opened on the outer periphery of the crank 3 axis. A screw block 33 is slidably connected to the bottom of the bed board 2, and an L-shaped guide column 34 is fixedly connected to the left wall of the screw block 33, and the L-shaped guide column 34 is movably engaged with the arc groove 32.

[0036] Specifically, the crank 3 initially limits the slide groove 24 through the sliding column 31, and the elastic strip 23 is in a compressed state. When the adjustment component operates and drives the screw block 33 to move to the right, the L-shaped guide column 34 drives the arc groove 32 to deflect the crank 3 forward, and the sliding column 31 squeezes the slide groove 24 downward, and the elastic strip 23 then drives the enclosure 22 to move down the maximum distance to avoid obstruction to the removal of the conveyor belt 58.

[0037] In this embodiment, the right end of the arc groove 32 extends to the right wall of the crank 3, and the elastic strip 23 is elastically connected to the lower wall of the bed board 2. Specifically, when the adjustment component is operating, the screw block 33 drives the L-shaped guide column 34 to move to the right and finally disengage from the arc groove 32. Under the elastic force restriction of the elastic strip 23, the crank 3 drives the arc groove 32 to be positioned at the disengaged position of the L-shaped guide column 34. When the adjustment component is reset subsequently, the screw block 33 can drive the L-shaped guide column 34 to re-connect with the right end of the arc groove 32, so as to stably drive the enclosure 22 to reset.

[0038] In this embodiment, the adjustment component also includes a screw rod 4 driven and installed in the center of the bottom of the bed board 2, and screw rods 41 are rotatably installed on the front and rear sides of the bottom of the bed board 2. A transmission belt 42 is movably connected between screw rods 1 4 and screw rods 2 41, the screw block 33 is meshingly connected with screw rod 1 4, and the load-bearing bar 5 is meshingly connected with screw rod 2 41.

[0039] Specifically, the control screw rod 4 is driven to rotate, and the screw rod 4 drives the screw rods 41 on both sides to rotate through the transmission belt 42. The screw rod 41 thereby drives the supporting bars 5 on the front and rear sides to move to the left, so as to drive the conveyor belt 58 to carry the patient to the top of the bed. During this period, the screw rod 4 rotates and simultaneously drives the screw block 33 to move to the right, so as to stably drive the enclosure 22 to move downward quickly, automatically and timely avoid the position relative to the conveyor belt 58, and avoid hindering the removal of the conveyor belt 58.

[0040] In this embodiment, the driving assembly includes a shaft tube 51 rotatably connected to the load-bearing bar 5, a bevel gear 52 is fixedly sleeved on the right side of the shaft tube 51, and the bevel gear 52 is meshingly connected to the bevel gear roller 54. A worm gear 53 is rotatably installed on the right side of the groove, and the worm gear 53 is slidably clamped in the inside of the shaft tube 51. An L-shaped sleeve 55 is slidably clamped on the left side of the inner cavity of the load-bearing bar 5, and a bevel gear 2 56 is rotatably connected to the left wall of the L-shaped sleeve 55. Bevel gear 2 56 is slidably clamped on the shaft tube 51, and bevel gear 2 56 is meshingly connected to the bevel gear roller 2 57. Bevel gear roller 2 57 is rotatably connected to the L-shaped sleeve 55. A driving worm 6 is drivingly installed on the right side of the groove, and the driving worm 6 is meshingly connected to the worm gear 53.

[0041] Specifically, the control driving worm 6 is driven to drive the worm gear 53 to rotate. Since the worm gear 53 is slidably engaged in the shaft tube 51, when the load-bearing bar 5 moves out of the groove in the bed board 2, the worm gear 53 can still transmit the power to the shaft tube 51, and the shaft tube 51 can be stably driven to rotate. Therefore, the shaft tube 51 drives the bevel gear 1 52 and the bevel gear 2 56 to rotate synchronously, and the bevel gear 1 52 engages to drive the bevel gear roller 1 54 to rotate counterclockwise, and the bevel gear 2 56 engages to drive the bevel gear roller 2 57 to rotate counterclockwise, and the bevel gear roller 1 54 releases the conveyor belt 58, and the bevel gear roller 2 57 reels the conveyor belt 58, thereby automatically transporting the patient.

[0042] In this embodiment, the bevel gear 1 52 and the bevel gear 2 56 have the same size specifications, and the transmission ratio of the bevel gear 1 52 to the bevel gear roller 1 54 is smaller than the transmission ratio of the bevel gear 2 56 to the bevel gear roller 2 57 .

[0043] Specifically, due to the action of the meshing tooth segments of the gear ring 59, the bevel roller 54 is driven to the right by the L-shaped shaft sleeve 55 while winding up the conveyor belt 58, so that it is automatically pulled out from under the patient's body while the conveyor belt 58 transports the patient. In combination with the transmission ratio of the bevel gear 1 52 and the bevel roller 1 54 being smaller than the transmission ratio of the bevel gear 2 56 and the bevel roller 2 57, when the bevel roller 1 54 and the bevel roller 2 57 rotate counterclockwise synchronously, the speed at which the bevel roller 2 57 winds up the conveyor belt 58 is faster, which can prevent the conveyor belt 58 from scattering from the left side, thereby facilitating and stably transporting the patient to the hospital bed, which is convenient, fast, safe and reliable.

[0044] In this embodiment, the fixing bolt 81 is movably engaged with the first clamping slot 82 , and the first clamping slot 82 and the second clamping slot 83 are distributed on the circumference of the rotation center of the telescopic bracket 8 , and the central angle formed by them is 90 degrees.

[0045] Specifically, the initial telescopic bracket 8 is horizontal and retracted on one side of the bed board 2, so as to avoid the extension of the telescopic bracket 8 affecting the transportation of the transfer bed when the infusion function is not provided. When infusion is required, the fixing bolt 81 is unscrewed from the slot 1 82, the telescopic bracket 8 is rotated to a vertical state, and the fixing bolt 81 is screwed into the slot 2 83, so that the telescopic bracket 8 can be fixed to avoid its shaking, thereby ensuring the continuous reliability of infusion medication.

[0046] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
