Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model
[0024] Embodiment
[0025] Next, in combination with Figures 1 to 4 , a new type of hand elevation pillow provided by the present application is introduced, including a pillow body 1, a traction sub-rope 3, a traction main rope 4, an adjustment device 6 and a hook device 5
[0026] Referring to Figure 1 , the pillow body 1 is long strip-shaped, suspension rings 2 are provided at the four corners of the pillow body 1, traction sub-ropes 3 are connected between the two suspension rings 2 on each long side of the pillow body 1, the two traction sub-ropes 3 are commonly connected to a traction main rope 4, the other end of the traction main rope 4 is connected to an adjustment device 6, the adjustment device 6 is used to contract and relax the traction main rope 4, and a hook device 5 for hanging traction is provided on the traction main rope 4
[0027] One end of the main traction rope 4 connected to the two sub-traction ropes 3 is connected with a slip ring 41. The two sub-traction ropes 3 jointly pass through the slip ring 41. The outer surface of the slip ring 41 is provided with friction stripes for increasing friction. The slip ring 41 with friction stripes can increase the friction between the slip ring 41 and the sub-traction ropes 3, so that the sub-traction ropes 3 between the two hanging rings 2 on each long side of the pillow body 1 stay at the set position. The angle of the pillow body 1 relative to the patient can be adjusted, so that the relative positions of the hands and the torso in the sitting and lying postures can be taken into account, improving the comfort level.
[0028] The adjustment device 6 includes a housing 60, a first rotating shaft 62, a second rotating shaft 63, a one-way bearing 66, a first conical wheel 64, a knob 7, a second conical wheel 65 and a fixing part;
[0029] Through holes 61 allowing the main traction rope 4 to pass through are provided at the upper and lower ends of the housing 60; a first rotating shaft 62 and a second rotating shaft 63 which are parallel to each other are horizontally arranged in the housing 60. The first rotating shaft 62 is threadedly connected to the side wall of the housing 60. The first rotating shaft 62 is rotatably installed with a first conical wheel 64 through a one-way bearing 66. One end of the first rotating shaft 62 extends out of the housing 60 and is connected with the knob 7. The second rotating shaft 63 is fixedly installed in the housing 60. The second rotating shaft 63 is rotatably installed with a second conical wheel 65 through a one-way bearing 66; the conical surfaces of the first conical wheel 64 and the second conical wheel 65 are complementarily arranged. The rotating directions of the first conical wheel 64 and the second conical wheel 65 are towards each other towards the joint surface. The first conical wheel 64 and the second conical wheel 65 form a clamping to jointly contract and relax the main traction rope 4; the fixing part is used for being fixed to the hospital bed.
[0030] Referring to Figure 4 , when the height of the pillow body 1 needs to be adjusted, the first rotating shaft 62 is screwed into the housing 60 until the first conical wheel 64 and the second conical wheel 65 form a clamping on the main traction rope 4. Under the action of the one-way bearing 66, the rotating directions of the first conical wheel 64 and the second conical wheel 65 are towards each other towards the joint surface, forming a one-way transmission. That is, at this time, the main traction rope 4 can be pulled downward with one hand, and at this time, the pillow body 1 moves upward to achieve position adjustment. When the pillow body 1 needs to be lowered, the first rotating shaft 62 is screwed out of the housing 60 until the first conical wheel 64 and the second conical wheel 65 release the clamping on the main traction rope 4, and the one-way transmission is released.
[0031] The hanging device 5 includes an inverted U-shaped chute 50 and a hook 51. The inverted U-shaped chute 50 is used to change the direction of the main traction rope 4. A hook 51 is rotatably installed at the top end of the inverted U-shaped chute 50. The hook 51 is used for hanging and fixing to an infusion pole of an infusion rack, etc. The rotational installation of the U-shaped chute and the hook 51 can ensure that the opening part of the inverted U-shaped chute 50 always faces downward when the main traction rope 4 is pulled and will not deflect.
[0032] At the top and both ports of the inverted U-shaped sliding groove 50, there are runners 52 for reducing the friction with the main traction rope 4, which reduces the resistance of pulling the main traction rope 4, further improves comfort and reduces the usage difficulty.
[0033] One end of the main traction rope 4 close to the housing 60 is coated with a rubber coating 42 for increasing friction. The rubber coating 42 can increase the surface friction, which is used to increase the release of the clamping of the main traction rope 4 by the first conical pulley 64 and the second conical pulley 65, and improve the reliability.
[0034] On the surfaces of the first conical pulley 64 and the second conical pulley 65, there are grooves 641 perpendicular to the length direction of the main traction rope 4. On the rubber coating 42, there are protrusions 43 adapted to the grooves 641. The engaging structure formed by the grooves 641 and the protrusions 43 further increases the effect of the first conical pulley 64 and the second conical pulley 65 releasing the clamping of the main traction rope 4, and improves the reliability.
[0035] The fixing part includes an L-shaped plate 67. One end of the L-shaped plate 67 is fixedly connected to the outer side wall of the housing 60 to form a downward-opening trough-shaped structure. On the L-shaped plate 67, there is a fastening screw 671 passing through the L-shaped plate 67 and abutting against the housing 60. The L-shaped plate 67 and the fastening screw 671 can clamp and fix the erected plate-like structure, such as the backrest of a hospital bed, the edge of a bed, etc.
[0036] In the housing 60, there is a connecting sliding sleeve 69 cooperating with the first rotating shaft 62. Inside the threaded connecting sleeve, there is a compression spring 691 for abutting against the inner wall of the housing 60 and the first rotating shaft 62. The compression spring 691 realizes the effect of pre-tightening and relaxing on the first rotating shaft 62, and improves the fixing effect between the first rotating shaft 62 and the outer side wall of the housing 60.
[0037] The fixing part includes a hook 68 and an elastic buckle 681. The outer side wall of the housing 60 is connected with a hook 68 through a flexible connecting piece 682. The opening part of the hook 68 is provided with an elastic buckle 681. The flexible connecting piece 682 includes any one of a rope, an iron chain, and multiple connecting rods. The hook 68 and the flexible connecting piece 682 can realize the hook-and-fix of a ring-shaped structure, such as a handle, a perforated bed edge, a frame-type hospital bed backrest, etc. The elastic buckle 681 can improve the hook-and-fix effect.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
