[0015] Example: Figs. 1-3As shown, the utility model provides a nursing storage cart, including a bottom frame 1, both sides of the top of the bottom frame 1 are fixedly connected to a lifting device 2, the tops of the two lifting devices 2 are fixedly connected to a storage table 3, one end of the storage table 3 is inserted and slidably connected to two drawers 31, the other end of the storage table 3 is provided with a groove 34 on the upper part, and an extension mechanism 4 is slidably provided between the grooves 34, the lifting device 2 includes a support leg 21, the bottom end of the support leg 21 is fixedly connected to one side of the top of the bottom frame 1, and the outer surface of the support leg 21 is slidably sleeved with a lifting device. The housing 22, the top of the lifting housing 22 is fixedly connected to one side of the bottom end of the storage platform 3, a screw rod 25 is inserted in the middle of the support leg 21, the middle outer surface of the screw rod 25 is threaded with a fixed block 23, the outer surface of the fixed block 23 is fixedly connected to the upper inner wall of the support leg 21, the upper outer surface of the screw rod 25 is fixedly sleeved with a shaft sleeve 24, the upper outer surface of the shaft sleeve 24 is fixedly connected to the upper inner wall of the lifting housing 22, the top of the screw rod 25 is fixedly connected to the first bevel gear 26, and the upper inner wall of the lifting housing 22 is rotatably connected to the transmission The outer surface of the transmission shaft 27 is fixedly sleeved with a second bevel gear 28, and the outer surface of the first bevel gear 26 is meshed with the outer surface of the second bevel gear 28. A motor 29 is fixedly installed on the upper part of one end of the lifting shell 22. The output end of the motor 29 passes through the lifting shell 22 and is fixedly connected to one end of the transmission shaft 27. The storage platform 3 drives the screw rod 25 to rotate under the transmission of the first bevel gear 26 and the second bevel gear 28 through the synchronous output of the two motors 29 in the two lifting devices 2, so that the screw rod 25 is rotated. The lifting platform 3 is lifted and lowered as a whole except for the lifting platform 22 and the fixed block 23, thereby realizing the lifting and lowering movement of the storage platform 3, helping the operator to adjust the height of the storage platform 3 up and down, and collecting and placing items through the two drawers 31 at one end of the storage platform 3.The extension mechanism 4 includes a first extension plate 41 and a second extension plate 42. One end of the first extension plate 41 and the second extension plate 42 are fixedly connected to two hinges 43. The outer surfaces of both sides of the groove 34 are slidably connected to the first slide rails 44. The top ends of the two first slide rails 44 are fixedly connected to the bottom end of the second extension plate 42. One end of the two first slide rails 44 is slidably sleeved with a second slide rail 45. One end of the two second slide rails 45 is fixedly connected to a pull rod 46. The outer surfaces of the two first slide rails 44 are provided with three limit grooves 40, which can be pulled outward by pulling the pull rod 46. The two second slide rails 45 are driven to slide linearly along the outer surface of the first slide rail 44. During the sliding process, the two first slide rails 44 are also driven to slide linearly along the outer surfaces on both sides of the groove 34. The three limit grooves 40 on both sides help the sliding first slide rail 44 to be limited and fixed. The operator can flip the first extension plate 41 so that the bottom end of the first extension plate 41 is against the top end of the two second slide rails 45 to realize the movement process of the extension area, thereby increasing the use area of the storage table 3. The hidden extension mechanism 4 improves the flexibility and space utilization of the storage table 3. The outer surfaces of both sides of the lifting shell 22 are fixedly connected with diagonal braces, and the two diagonal braces are fixedly connected to one side of the bottom end of the storage platform 3. Two hooks 33 are fixedly installed at the other end of the storage platform 3, and the two hooks 33 are distributed in a mirror image. One of the drawers 31 is provided with multiple compartments, and one end of the bottom frame 1 is fixedly connected to a dirt bucket 10, which is rectangular. The bottom end of the bottom frame 1 is fixedly connected to four universal wheels, and the four universal wheels are distributed in a rectangular array. The role of the diagonal brace is to increase the stability of the storage platform 3 and improve the load-bearing capacity of the storage platform 3. The two hooks 33 are for helping the operator to hang items such as hanging bottles and hanging bags conveniently. The compartments opened inside the drawer 31 are for increasing the classification of items in the drawer 31, realizing different storage spaces for items, and facilitating the rational use of space. The role of the dirt bucket 10 is to facilitate nursing staff to collect and store some discarded items for subsequent cleaning. The four universal wheels are for flexible movement in any direction. The first extension plate 41 and the second extension plate 42 are the same size, and the two hinges 43 are distributed in a mirror image. The two first slide rails 44 and the second slide rails 45 are also distributed in a mirror image. The outer surfaces of both sides of the groove 34 are fixedly installed with spring pins used in conjunction with the limit groove 40. The first extension plate 41 and the second extension plate 42 of the same size are to facilitate the operator to maintain the same horizontal height after flipping and extending, so that the placement plane is flatter. The two mirror image hinges 43 are to facilitate the connection of the first extension plate 41 and the second extension plate 42. The spring pins located on the outer surfaces of both sides of the groove 34 limit and fix the first slide rail 44 during the sliding of the two first slide rails 44. When the first slide rail 44 moves to a certain extent, the spring pin pushes out to penetrate the limit groove 40, making it convenient for the operator to place objects.
[0016] Working principle: When it is necessary to lift or lower objects, the motor 29 in the lifting device 2 is started, and the output end of the motor 29 drives the transmission shaft 27 to rotate, and the rotating transmission shaft 27 drives the second bevel gear 28 to rotate, thereby driving the first bevel gear 26 to rotate horizontally, and the rotating first bevel gear 26 drives the screw rod 25 to rotate vertically, and the vertically rotating screw rod 25 is threadedly moved up and down through the fixed block 23 fixedly connected to the inner wall of the support leg 21, thereby driving the lifting shell 22 to slide up and down on the outer surface of the support leg 21 through the connection and fixation of the shaft sleeve 24, thereby lifting and lowering the storage table 3, and realizing the up and down movement of the storage table 3. The operator can take or store nursing appliances or medicines through the two drawers 31, and hang and discard items through the two hooks 33 at one end and the waste bucket 10; When the storage surface needs to be expanded, the operator puts his hand deep into the inside of the groove 34 and pulls it outward through the pull rod 46, so that the two second slide rails 45 slide and withdraw synchronously along the outer surfaces of the two first slide rails 44. When it is withdrawn to a certain distance, it drives the two first slide rails 44 to slide linearly along the outer surfaces on both sides of the groove 34, thereby driving the second extension plate 42 and the first extension plate 41 to slide and extend outward. When sliding to a certain distance, it is fixed by the three limit grooves 40 and the spring pin. Then, the first extension plate 41 is flipped to one side through the two hinges 43 so that the first extension plate 41 is placed on the top of the two second slide rails 45. The operator can place items on the first extension plate 41 and the second extension plate 42, thereby expanding the usable area.
[0017] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
