Description

Technical Field

[0001] This utility model relates to the field of elderly care technology, and in particular to a service vehicle for elderly care. Background Technology

[0002] Elderly care is a professional care service provided for elderly people who have difficulty moving around or whose physical functions are declining. It covers aspects such as daily living, dietary care, and health monitoring. With the arrival of an aging society, the demand for elderly care is increasing, especially for elderly people who are bedridden or have difficulty walking. The convenience and comfort of care are particularly important.

[0003] Nursing carts are important auxiliary tools in elderly care, often used to transport meals, medicines, or nursing supplies. For example, when elderly people with mobility issues eat in bed, caregivers need to move the nursing cart to the edge of the bed so that the dining table is close to the elderly person, making it easier for them to eat.

[0004] Currently, most elderly care carts on the market use swivel casters with pedal-type locking mechanisms to enable movement and fixation. However, in actual use, when the cart is pushed to the edge of the bed, the bottom structure often extends into the space under the bed, obstructing the locking mechanism of the casters. This design flaw forces caregivers to bend over or lean over to lock the casters one by one under the bed, increasing workload and reducing care efficiency. Therefore, a service cart for elderly care is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a service cart for elderly care, which aims to improve the problem mentioned in the prior art that "when the care cart is in use, its bottom structure often extends into the space under the bed, making it difficult for caregivers to lock the casters."

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a service cart for elderly care, including a base plate 1, a column 2 fixedly connected to the top of the base plate 1, and a top plate 3 fixedly connected to the top of the column 2. The end of the base plate 1 away from the threaded rod 65 is pushed into the bottom of the bed, so that the column 2 fits against the edge of the bed. At the same time, the top plate 3 at the top of the column 2 can be placed horizontally above the bed to facilitate the elderly person eating in bed. The bottom of the base plate 1 is fixedly connected to a caster wheel 4, which can move the base plate 1. The caster wheel 4 is provided with a pedal-type lock 5 for locking the caster wheel 4. The caster wheel 4 with the pedal-type lock 5 is prior art, so it will not be described in detail here. The base plate 1 is provided with a locking mechanism 6, and the bottom of the base plate 1 is provided with a positioning mechanism 7.

[0033] Reference Figure 2 - Figure 4The locking mechanism 6 includes a sliding frame 61, which is slidably connected to the outer wall of the base plate 1. A disc 62 is fixedly connected to the inner wall of the sliding frame 61. When the sliding frame 61 slides downward, it drives the disc 62 to move downward synchronously. The central axis of the caster wheel 4 is concentric with the disc 62. A slider 63 is slidably connected to the inner wall of the disc 62. When the disc 62 moves downward, it drives the slider 63 to move downward synchronously. The disc 62 has a circular disc-shaped structure. The slider 63 moves in a circular motion around the center of the disc 62. The circumferential sliding connection between the slider 63 and the disc 62 does not interfere with the rotation of the caster wheel 4. A connecting rod 64 is hinged to the bottom of the base plate 1. The end of the connecting rod 64 away from the slider 63 is hinged to the top of the pedal-type lock 5. When the slider 63 moves downward, it pushes the connecting rod 64 downward, causing the connecting rod 64 to press the pedal-type lock 5 downward, thereby locking the universal wheel 4. A threaded rod 65 is rotatably connected through the inner wall of the base plate 1. The threaded rod 65 is threadedly connected to the slide frame 61. The rotation of the threaded rod 65 can drive the slide frame 61, which is threadedly connected to it, to slide up and down on the outer wall of the base plate 1. A handle 66 is fixedly connected to the top of the threaded rod 65. The handle 66 makes it convenient for caregivers to rotate the threaded rod 65.

[0034] Reference Figure 2 - Figure 3 The positioning mechanism 7 includes a bracket 71, which is fixedly connected to the bottom of the slide frame 61. When the slide frame 61 slides downward, it will drive the bracket 71 to slide downward synchronously. The inner wall of the bracket 71 is slidably connected to a positioning rod 72. The bottom of the positioning rod 72 is fixedly connected to a suction cup 73. When the positioning rod 72 moves downward, it can press the suction cup 73 firmly onto the tile on the ground, so that the suction cup 73 can be attracted to the tile. At this time, the suction cup 73, together with the positioning rod 72, the bracket 71 and the slide frame 61, can improve the stability of the base plate 1. The top of the positioning rod 72 is fixedly connected to a limit block 74. The outer wall of the positioning rod 72 is fitted with a spring 75. One end of the spring 75 is fixedly connected to the bottom of the limit block 74, and the other end of the spring 75 is fixedly connected to the outer wall of the bracket 71. When the bracket 71 moves downward, it will drive the spring 75 to move downward synchronously. At this time, the spring 75 will pull the limit block 74 downward, so that the limit block 74 will drive the positioning rod 72 to move downward synchronously.

[0035] Working principle: During use, the base plate 1 is moved by the casters 4, pushing the end of the base plate 1 away from the threaded rod 65 into the bottom of the bed, so that the upright 2 fits against the edge of the bed. At the same time, the top plate 3 on the top of the upright 2 can be placed horizontally above the bed for the elderly to eat in bed. Then, the threaded rod 65 is rotated by the handle 66, so that the threaded rod 65 drives the sliding frame 61 connected to it to slide downward on the outer wall of the base plate 1. As the sliding frame 61 slides downward, it drives the disc 62 to move downward in sync. As the disc 62 moves downward, it drives the slider 63 to move downward in sync. At this time, the slider 63 pushes the connecting rod 64 downward, so that the connecting rod 64 presses the pedal-type lock 5 downward, thereby locking the casters 4. The four sets of casters 4 on the base plate 1 will be locked simultaneously, making the locking of the casters 4 more convenient, so that caregivers can take care of the elderly to eat more efficiently.

[0036] As the sliding frame 61 slides downward, it drives the bracket 71 to slide downward simultaneously. As the bracket 71 moves downward, it drives the spring 75 to move downward simultaneously. At this time, the spring 75 pulls down the limiting block 74, causing the limiting block 74 to drive the positioning rod 72 to move downward simultaneously. The downward movement of the positioning rod 72 can press the suction cup 73 firmly onto the tile on the ground, so that the suction cup 73 can be attached to the tile. At this time, the suction cup 73, together with the positioning rod 72, the bracket 71 and the sliding frame 61, can improve the stability of the base plate 1 and prevent the base plate 1 from shifting, so that the elderly can eat on the top plate 3.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
