Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation nursing, and more specifically, to a multifunctional transfer machine lifting device and a use method thereof. Background Art

[0002] It is known that with the passage of time, the number of people who are bedridden for a long time due to diseases, injuries, aging and other reasons is increasing; and these people face many difficulties in their daily lives, such as the problem of displacement; displacement refers to the transfer of a bedridden person from one safe and comfortable position to another safe and comfortable position, such as from a bed to a wheelchair, from a wheelchair to a toilet, etc.; it is known that traditional displacement methods mainly rely on manpower, such as caregivers directly picking up or helping bedridden people to move; however, this method has many disadvantages: 1. For caregivers, the displacement process is extremely heavy physical labor, especially when facing heavy bedridden people, which can easily cause caregivers to be injured; 2. 1. Manual shifting may not guarantee the body balance and stability of the bedridden person, increasing the risk of injury; and, this method is difficult to ensure comfort during the shifting process, which may cause physical discomfort and psychological pressure on the bedridden person; therefore, in recent years, hanging shifters and clamp-type shifters have appeared, such as the electric shifter KQ-782 under Japan's Balem Corporation, which uses a strap to lift people to move, but the product is relatively cumbersome to use and takes up a large amount of space; for example, the manual shifter MKX-YWJ-01A developed by the domestic MyConsun company, but this product uses a double-sided clamping method to shovel the elderly onto the shifter, which has a relatively high risk of squeezing the elderly's buttocks.

[0003] At present, the lifting and shifting machines on the market are mainly hydraulic lifting and shifting machines and electric lifting and shifting machines. However, both of them have some problems in actual use:

[0004] If a hydraulic lift is used, the hydraulic pump is high and large in size. When the hydraulic lift is lowered, the hydraulic pump pedal needs to be stepped on to the bottom, resulting in a large pedal operation range. In addition, the hydraulic lift is continuously lowered, and it is difficult to control the stop position. Therefore, the hydraulic lift is difficult to operate when in use.

[0005] If an electric lifting and transfer machine is used, it not only needs to be equipped with batteries or mobile power supplies, but also needs to be waterproofed. Therefore, it is difficult to achieve safe and reliable use, and there is a risk of leakage when assisting bathing.

[0079] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0080] As attached Figure 1-14 A multifunctional lifting device for a transfer machine is shown, the lifting device for a transfer machine comprises: a seat plate component 1, a control box 2 and a base component 3;

[0081] Support columns 4 are fixedly installed on both sides of the bottom of the assembly 1 on the seat plate near the front;

[0082] Support guide tubes 5 are fixedly installed on both sides of the top of the base assembly 3 near the front;

[0083] The support conduit 5 is movably sleeved on the outer surface of the support column 4. The tops of the two support conduits 5 are fixedly mounted with a lifting and rotating member housing 6. The interior of the lifting and rotating member housing 6 is rotatably connected with a rotating shaft 61. A lifting mechanism 7 is arranged between the rotating shaft 61 and the support column 4.

[0084] The control box 2 is fixedly installed in the middle of the top of the base assembly 3. The inner part of the control box 2 near the top is rotatably connected with a transmission shaft 21. The two ends of the transmission shaft 21 are respectively fixedly connected to the two rotating shafts 61.

[0085] The rotation of the transmission shaft 21 will drive the rotating shaft 61 to rotate;

[0086] A pedal assembly 22 is provided on the front of the control box 2, and a driving shaft 23 and a driven shaft 24 are rotatably connected inside the control box 2;

[0087] A transmission mechanism 8 is provided between the driven shaft 24 and the transmission shaft 21;

[0088] A clutch locking mechanism 9 is provided between the driving shaft 23 and the driven shaft 24;

[0089] The foot pedal assembly 22 is connected to the driving shaft 23 through the ratchet assembly 10 .

[0090] When the control box 2 is in operation, it will drive the support column 4 to move up and down along the support guide tube 5, thereby driving the seat plate component 1 to move up and down. In this way, the lifting function of the lifting device of the transfer machine is realized;

[0091] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the lifting mechanism 7 includes: a lifting gear 71 and a sawtooth groove 72;

[0092] The lifting gear 71 is fixedly sleeved on the surface of the rotating shaft 61, and the lifting gear 71 rotates inside the lifting rotating member housing 6. A number of evenly distributed serrated grooves 72 are opened on the surface of the support column 4 along the axial direction of the support column 4. The lifting gear 71 is inserted into the support guide tube 5, and the lifting gear 71 is meshed and connected with the serrated groove 72.

[0093] The rotation of the transmission shaft 21 drives the rotating shaft 61 to rotate, thereby driving the lifting gear 71 to rotate. The lifting gear 71 is engaged with the sawtooth groove 72, so that the rotation of the lifting gear 71 drives the support column 4 to be lifted or lowered.

[0094] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the transmission mechanism 8 includes: a flywheel 81, a first bevel gear 82, a first gear 83, a second gear 84, a third gear 85, a fourth gear 86, a second bevel gear 87 and a third bevel gear 88;

[0095] The first bevel gear 82 is fixedly sleeved on the transmission shaft 21, the second bevel gear 87 and the first gear 83 are fixedly sleeved on the same rotating shaft rotatably connected to the inner wall of the control box body 2, the first bevel gear 82 is meshedly connected with the second bevel gear 87, the second gear 84 and the third gear 85 are fixedly sleeved on the same rotating shaft rotatably connected to the inner wall of the control box body 2, the first gear 83 is meshedly connected with the second gear 84, the fourth gear 86, the flywheel 81 and the third bevel gear 88 are fixedly sleeved on the driven shaft 24, and the third gear 85 is meshedly connected with the fourth gear 86.

[0096] If the driving shaft 23 drives the driven shaft 24 to rotate, the fourth gear 86, the flywheel 81 and the third bevel gear 88 on the driven shaft 24 rotate coaxially;

[0097] The third gear 85 is meshed with the fourth gear 86, so that the fourth gear 86 drives the third gear 85 to rotate and drives the second gear 84 coaxial with the third gear 85 to rotate;

[0098] The first gear 83 is meshed with the second gear 84, so that the second gear 84 rotates to drive the first gear 83 to rotate and drive the second bevel gear 87 coaxial with the first gear 83 to rotate;

[0099] The first bevel gear 82 is meshed with the second bevel gear 87, so that the second bevel gear 87 rotates to drive the first bevel gear 82 to rotate and drive the transmission shaft 21 fixedly sleeved by the first bevel gear 82 to rotate, so that the driven shaft 24 rotates to drive the transmission shaft 21 to rotate, thereby achieving the transmission effect of the transmission mechanism 8;

[0100] The flywheel 81 mainly functions to increase the inertia of the movement, so as to ensure that the lifting device of the transfer machine remains stable during the lifting movement.

[0101] The transmission mechanism 8 can be changed into a worm gear structure, which can replace the gear transmission structure of this solution as long as it can ensure the deceleration and smooth operation of the structure.

[0102] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the clutch locking mechanism 9 includes: a fourth bevel gear 91, a fifth bevel gear 92, a first spline 93, a second spline 94, a clutch connecting rod 95 and a clutch handle 96;

[0103] The fourth bevel gear 91 and the fifth bevel gear 92 are both movably sleeved on the surface of the driving shaft 23, and the fourth bevel gear 91 and the fifth bevel gear 92 are both meshed and connected with the third bevel gear 88. The clutch handle 96 is fixedly installed on the top of the clutch connecting rod 95. The first spline 93 and the second spline 94 rotate at both ends of the clutch connecting rod 95 respectively. The first spline 93 and the second spline 94 are connected to the driving shaft 23 through the first flat key 97 and the second flat key 98 respectively. The first spline 93 slides on the first flat key 97 and the driving shaft 23, and the second spline 94 slides on the second flat key 98 and the driving shaft 23.

[0104] The first spline 93 and the second spline 94 are detachably connected to the fourth bevel gear 91 and the fifth bevel gear 92 , respectively.

[0105] Among them, since the fourth bevel gear 91 and the fifth bevel gear 92 are movably sleeved on the surface of the driving shaft 23, and the fourth bevel gear 91 and the fifth bevel gear 92 are both meshed with the third bevel gear 88, if the driving shaft 23 is not connected to the fourth bevel gear 91 and / or the fifth bevel gear 92, the driving shaft 23 cannot drive the fourth bevel gear 91 and / or the fifth bevel gear 92 to rotate, and further cannot drive the third bevel gear 88 to rotate, and cannot drive the driven shaft 24 sleeved by the third bevel gear 88 to rotate; therefore, the clutch handle 96 is used to drive the clutch connecting rod 95 to move left or right:

[0106] When the clutch handle 96 drives the clutch link 95 to move to the far right, the clutch link 95 drives the first spline 93 to slide rightward on the first flat key 97 and the driving shaft 23, and the first spline 93 is fixedly connected to the fourth bevel gear 91; on the other hand, it also drives the second spline 94 to slide rightward on the second flat key 98 and the driving shaft 23, so that the second spline 94 is separated from the fifth bevel gear 92; and then, if the driving shaft 23 rotates, the third bevel gear 88 will be driven to rotate through the fourth bevel gear 91, so that the transmission mechanism 8 and the lifting mechanism 7 can achieve the lifting effect;

[0107] The rotation direction of the fifth bevel gear 92 is opposite to the rotation direction of the fourth bevel gear 91, and the fifth bevel gear 92 will not lock the driving shaft 23 from rotating;

[0108] When the clutch handle 96 drives the clutch connecting rod 95 to move to the far left, the clutch connecting rod 95 drives the first spline 93 to slide to the left on the first flat key 97 and the driving shaft 23, and separates the first spline 93 from the fourth bevel gear 91; on the other hand, it drives the second spline 94 to slide to the left on the second flat key 98 and the driving shaft 23, and the second spline 94 is fixedly connected to the fifth bevel gear 92; and then, if the driving shaft 23 rotates, the third bevel gear 88 will be driven to rotate through the fifth bevel gear 92, so that the transmission mechanism 8 and the lifting mechanism 7 can achieve the effect of descending;

[0109] The rotation direction of the fifth bevel gear 92 is opposite to the rotation direction of the fourth bevel gear 91, and the fourth bevel gear 91 will not lock the driving shaft 23 from rotating;

[0110] When the clutch handle 96 drives the clutch connecting rod 95 to move to the middle, the clutch connecting rod 95 not only drives the first spline 93 to be fixedly connected with the fourth bevel gear 91; it also drives the second spline 94 to be fixedly connected with the fifth bevel gear 92; and then the fourth bevel gear 91 and the fifth bevel gear 92 are both difficult to rotate, thereby achieving the effect of locking the rotation of the driving shaft 23 at the same time, so that the external force cannot drive the driving shaft 23 to rotate, and therefore the clutch locking mechanism 9 plays the role of locking the lifting.

[0111] Among them, the gear meshing and other related structures in the clutch locking mechanism 9 can be replaced by similar structures, as long as the rotation reversal can be guaranteed, they can replace this solution;

[0112] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the foot pedal assembly 22 includes: a pedal member 221, a fixing member 222, a recovery plate 223, a torsion spring 224, a deflector block 225, a first fixing shaft 226, a second fixing shaft 227 and a rotating member 228;

[0113] The pedal member 221 is fixedly connected to the rotating member 228, the first fixed shaft 226 and the second fixed shaft 227 are both fixedly installed inside one end of the fixed member 222, the detent block 225 and the torsion spring 224 are both movably sleeved on the first fixed shaft 226, and the detent block 225 is connected to the first fixed shaft 226 through the torsion spring 224, the recovery plate 223 and the rotating member 228 are both movably sleeved on the second fixed shaft 227, the shape of the recovery plate 223 is set to be a semicircular shape, the shape of the rotating member 228 is set to be a circle with partial sector teeth, the radius of the recovery plate 223 is larger than the radius of the rotating member 228, the detent block 225 is engaged with the rotating member 228, the recovery plate 223 and the rotating member 228 are connected by a multi-speed resettable hinge, and the other end of the fixed member 222 is fixedly connected to the ratchet assembly 10.

[0114] When the user steps on and lifts the pedal member 221, the pedal member 221 is fixedly connected to the rotating member 228, and the recovery plate 223 is connected to the rotating member 228 through a multi-position resettable hinge, which drives the rotating member 228 and the recovery plate 223 to rotate around the second fixed shaft 227 as the center of the circle, and the deflector block 225 is connected to the first fixed shaft 226 through the torsion spring 224. If the deflector block 225 rotates around the first fixed shaft 226, it will be subjected to the elastic force of the torsion spring 224 to reset.

[0115] When the rotating member 228 rotates in one direction, the sector teeth on the rotating member 228 are engaged with the deflection block 225. At this time, the pedal assembly 22 is in the working state, and the rotation of the rotating member 228 is blocked, which drives the fixed member 222 where the rotating member 228 and the deflection block 225 are located to move along with the pedal member 221, so that the ratchet assembly 10 connected to the fixed member 222 will undergo corresponding changes;

[0116] When the rotating member 228 rotates in the other direction, some of the sector teeth on the rotating member 228 will be disengaged from the blocking block 225, and then the rotating member 228 drives the recovery plate 223 to lift and rotate the blocking block 225 away from some of the sector teeth on the rotating member 228, so that some of the sector teeth on the rotating member 228 are not engaged with the blocking block 225, and the foot pedal assembly 22 is in a non-working state, and the pedal member 221 can be folded;

[0117] When the pedal member 221 drives the rotating member 228 to rotate to a certain angle, the rotating member 228 drives the recovery plate 223 to rotate through the resettable hinge, and then the rotating member 228 drives the recovery plate 223 to break away from the contact with the deflector block 225. At this time, the reset torsion spring 224 re-engages the deflector block 225 with part of the sector teeth on the rotating member 228, and then the pedal assembly 22 resumes the working state;

[0118] Therefore, the foot pedal assembly 22 can drive the ratchet assembly 10 to undergo corresponding changes and also has a folding function.

[0119] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the ratchet assembly 10 includes: a driving wheel 101, a ratchet body 102, a pawl 103 and a spring 104;

[0120] The outer surface of the driving wheel 101 is fixedly connected to the end of the fixing piece 222, the driving wheel 101 is movably sleeved on the driving shaft 23, the ratchet body 102 is installed on the driving shaft 23 through the third flat key 105, the pawl 103 is installed on the side of the driving wheel 101 through the spring 104, and the pawl 103 is clamped with the ratchet body 102, and a driving wheel cover 106 covering the ratchet body 102 is fixedly installed on the side of the driving wheel 101.

[0121] When the fixing member 222 rotates with the driving shaft 23 as the center, the driving wheel 101 sleeved on the driving shaft 23 will be driven to rotate. Since the ratchet body 102 is installed on the driving shaft 23 through the third flat key 105, the pawl 103 installed by the driving wheel 101 through the spring 104 is engaged with the ratchet body 102. When the fixing member 222 rotates downward, the driving wheel 101 rotates and drives the pawl 103 to drive the ratchet body 102 to rotate. The ratchet body 102 drives the driving shaft 23 to rotate through the third flat key 105; when the fixing member 222 rotates upward, the pawl 103 will not drive the ratchet body 102 to rotate, and the driving shaft 23 will not rotate; and then when the fixing member 222 performs intermittent upward and downward motions, the ratchet body 102 will intermittently rotate in the same direction, thereby providing the driving shaft 23 with the required power, so that the driving shaft 23 can and can only rotate in one direction; therefore, the ratchet assembly 10 achieves the effect of unidirectional rotation of the driving shaft 23.

[0122] Among them, the ratchet assembly 10 can be changed into a rotating spring pin locking structure;

[0123] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, a sliding groove 25 for sliding the clutch handle 96 is provided on the front of the control box 2, so that the movement of the clutch handle 96 is not hindered and the user can use the width of the sliding groove 25 as a reference for the moving distance.

[0124] As attached Figure 1-14 As shown, a method for using a multifunctional lifting device for a transfer machine includes a multifunctional lifting device for a transfer machine, and the specific operation steps are as follows:

[0125] S1: The patient sits on the seat plate component 1 of the lifting device of the transfer machine, and the adjustment is made according to the patient's own condition: in the initial state, if the seat plate component 1 needs to be adjusted upward, enter S2;

[0126] If it is necessary to lower the seat plate assembly 1, then enter S3;

[0127] If the height of the component 1 on the seat plate meets the requirements, the process goes to S4;

[0128] S2: Adjust the foot pedal assembly 22 to the working state, then move the clutch handle 96 to the rightmost position, and control the seat assembly 1 to rise by stepping on or pressing the pedal member 221; then return to S1;

[0129] S3: Adjust the foot pedal assembly 22 to the working state, then move the clutch handle 96 to the far left, and control the seat assembly 1 to descend by stepping on or pressing the pedal member 221; then return to S1;

[0130] S4: Check that the clutch handle 96 is in the middle, adjust the lifting device of the transfer machine to the self-locking state; adjust the foot pedal assembly 22 to the non-working state, and fold the foot pedal assembly 22; then return to S1.

[0131] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the initial state of the lifting device of the transfer machine: the clutch handle 96 is in the middle, the first spline 93 and the second spline 94 at both ends of the clutch connecting rod 95 are respectively connected to the fourth bevel gear 91 and the fifth bevel gear 92, and the third bevel gear 88 is locked;

[0132] The pedal assembly 22 is in a non-working state: the recovery plate 223 lifts up the blocking block 225, and the blocking block 225 is not engaged with the rotating member 228.

[0133] In a preferred embodiment, as shown in the attached Figure 1-14 As shown, the pedal assembly 22 is changed from the non-working state to the working state: the pedal member 221 is rotated to restore the blocking block 225 to the engagement with the rotating member 228 .
