Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical trolley technology, and in particular to a side-front bidirectional pull-out nursing trolley. Background Technology
[0002] Nursing carts are a type of mobile storage platform commonly equipped in clinical wards. They consist of a tabletop, multiple drawers, and bottom casters. They are used to centrally store and transport medicines, instruments, and dressings needed for procedures such as dressing changes and infusions. They are equivalent to a mobile workstation by the bedside. With the help of nursing carts, nursing staff do not need to frequently travel between the treatment room and the bed when performing various bedside procedures, which can effectively shorten the work path.
[0003] In practical use, when nursing carts are used in areas such as extra-bed wards and corridors, some operational limitations are exposed due to different spatial conditions. These places are usually narrow passages and the beds are closely spaced. Most of the movable trays or drawers on existing nursing carts can only be pulled out in one direction. Once the cart is blocked by surrounding beds, IV stands or other equipment and cannot be moved or turned, nursing staff often cannot pull out the drawer on the side that needs to be operated. At this time, they can only use the limited gap to move the cart repeatedly, or even need to remove the entire cart from the current work area, adjust the orientation from the outside and push it back in. This series of adjustment actions not only consumes physical strength and time, but is also prone to collisions with surrounding facilities. Utility Model Content
[0004] The purpose of this utility model is to provide a side-front bidirectional pull-out nursing trolley. In wards with extra beds or narrow corridors, the side pull-out frame slides out along the side of the base frame, and the front pull-out frame drives the movable tray to extend forward. Items can be retrieved from multiple directions without moving the trolley body, flexibly adapting to limited spaces and effectively solving the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A two-way pull-out nursing trolley includes a first fixed tray and a second fixed tray. Multiple support columns are fixedly connected between the first and second fixed trays. A push-pull handle is fixedly connected to one side of the second fixed tray. Multiple movable tray assemblies are arranged vertically between the support columns. Each movable tray assembly includes a support frame, a base frame, a side pull frame, and a front pull frame. The support frame is detachably fixed between the support columns. An installation groove is provided at the upper end of the support frame. The base frame is fixedly installed in the installation groove. The side pull frame is slidably connected to the base frame. The front pull frame is slidably connected to the side pull frame. A movable tray is fixedly connected to the front pull frame.
[0006] Preferably, rollers are fixedly installed at the four corners of the lower end of the first fixed tray, and the rollers are used to move the nursing cart.
[0007] Preferably, the base frame includes two first base frame strips, and two second base frame strips are fixedly connected between the two first base frame strips to form a rectangular structure. Each second base frame strip has a first limiting groove on its front and rear side walls. Each second base frame strip has a plurality of first bearing balls rotatably mounted on its upper surface. The base frame formed by the first and second base frame strips provides an installation base for the side pull frame. The first limiting grooves and the first bearing balls provide guidance and support for the lateral sliding of the side pull frame.
[0008] Preferably, the side pull frame includes two first side pull frame strips, two second side pull frame strips are fixedly connected between the two first side pull frame strips, and a plurality of reinforcing ribs are fixedly connected between the two first side pull frame strips and the second side pull frame strips. The side pull frame formed by the first side pull frame strips and the second side pull frame strips is used to realize the lateral pull-out of the movable pallet and to provide a load-bearing foundation for the front pull frame, so that the movable pallet can be pulled out forward through the front pull frame.
[0009] Preferably, the upper end of the first side pull frame edge strip is provided with a first bearing groove, and a first limiting slider is fixedly installed on the first side pull frame edge strip located on both sides of the first bearing groove. The longitudinal section of the first limiting slider is L-shaped. The lower end of the second side pull frame edge strip is provided with a second bearing groove, and a second limiting slider is fixedly installed on the second side pull frame edge strip located on the front and rear sides of the second bearing groove. The longitudinal section of the second limiting slider is L-shaped. The second bearing groove is in rolling cooperation with a plurality of first bearing balls, and the second limiting slider is slidably connected in the corresponding first limiting groove. The side pull frame slides relative to the second base frame edge strip through the rolling cooperation between the second bearing groove of the second side pull frame edge strip and the first bearing balls, and is prevented from detaching by the sliding cooperation between the second limiting slider and the first limiting groove.
[0010] Preferably, the front pull frame includes two first front pull frame side strips, and two second front pull frame side strips are fixedly connected between the two first front pull frame side strips. Each of the two side walls of the first front pull frame side strip is provided with a second limiting groove. A plurality of second bearing balls are rotatably installed on the lower end face of the first front pull frame side strip located between the two second limiting grooves. The second bearing balls roll into the corresponding first bearing groove, and the second limiting groove is slidably connected to the corresponding first limiting slider. The front pull frame slides forward relative to the first side pull frame side strip through the rolling engagement of the second bearing balls and the first bearing groove, realizing the forward pull-out of the movable tray, and is prevented from detaching by the sliding engagement of the second limiting groove and the first limiting slider.
[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the movable tray assembly is formed by a base frame, a side pull frame, and a front pull frame sliding together in sequence. The second side strip of the base frame is provided with a first limiting groove and a first bearing ball. The second side strip of the side pull frame is fastened to the first bearing ball of the base frame through its second bearing groove, achieving rolling support. At the same time, the second limiting slider cooperates with the first limiting groove to guide the side pull frame to move smoothly laterally, driving the tray to extend from the side of the vehicle body. The lower end of the first side strip of the front pull frame is equipped with a second bearing ball. The ball rolls along the first bearing groove on the first side strip of the side pull frame, and its second limiting groove engages with the first limiting slider of the side pull frame, providing a straight guide for forward pulling. Thus, in situations where the passage is narrow, the distance between beds is insufficient, and the trolley is difficult to turn, nursing staff can choose to pull out the tray laterally or forward to retrieve items according to the available space.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] In this embodiment, as Figures 1-8 As shown, the present invention provides a side-front bidirectional pull-out nursing trolley, including a first fixed tray 1 and a second fixed tray 2. Multiple support columns 4 are fixedly connected between the first fixed tray 1 and the second fixed tray 2. A push-pull handle 3 is fixedly connected to one side of the second fixed tray 2. Multiple movable tray assemblies 5 are arranged vertically between the multiple support columns 4. The movable tray assembly 5 includes a load-bearing frame 6, a base frame 8, a side pull frame 9, and a front pull frame 10. The load-bearing frame 6 is detachably fixed between the multiple support columns 4. An installation groove 7 is opened at the upper end of the load-bearing frame 6. The base frame 8 is fixedly installed in the installation groove 7. The side pull frame 9 is slidably connected to the base frame 8. The front pull frame 10 is slidably connected to the side pull frame 9. A movable tray 11 is fixedly connected to the front pull frame 10.
[0016] Rollers 12 are fixedly installed at the four corners of the lower end of the first fixed tray 1, so that it can be smoothly turned when pushed in narrow places such as extra bed wards or corridors, providing a basis for subsequent multi-directional pull-out operations.
[0017] The base frame 8 includes two first base frame side strips 13, and two second base frame side strips 14 are fixedly connected between the two first base frame side strips 13 to form a rectangular structure. Each second base frame side strip 14 has a first limiting groove 15 on its front and rear side walls. Each second base frame side strip 14 has multiple first bearing balls 16 rotatably installed on its upper surface. The first bearing balls 16 provide rolling support for the lateral sliding of the side pull frame 9, which can effectively reduce the pulling resistance and allow the side pull frame 9 to slide out smoothly without colliding with the surrounding facilities. In this embodiment, the side pull frame 9 includes two first side pull frame strips 17, and two second side pull frame strips 18 are fixedly connected between the two first side pull frame strips 17. Multiple reinforcing ribs are fixedly connected between the two first side pull frame strips 17 and the second side pull frame strips 18. A first bearing groove 19 is provided at the upper end of the first side pull frame strip 17. First limiting sliders 20 are fixedly installed on both sides of the first side pull frame strip 17 located at the first bearing groove 19. The longitudinal section of the first limiting slider 20 is L-shaped. A second bearing groove 21 is provided at the lower end of the second side pull frame strip 18. Second limiting sliders 22 are fixedly installed on the front and rear sides of the second side pull frame strip 18 located at the second bearing groove 21. The longitudinal section of the second limiting slider 22 is L-shaped. The second bearing groove 21 and multiple first bearing... The bearing ball 16 rolls in contact with the first bearing ball, while the second limiting slider 22 slides within the corresponding first limiting groove 15. When items need to be taken out or put in from the side of the vehicle, a lateral pulling force is applied to the side pull frame 9, and the second bearing groove 21 rolls smoothly along the first bearing ball 16, causing the side pull frame 9, along with the front pull frame 10 and the movable tray 11, to extend from the side. At the same time, the second limiting slider 22 slides within the corresponding first limiting groove 15. When the side pull frame 9 is pulled out to its maximum stroke, the second limiting slider 22 enters the groove near the outer side of the first limiting groove 15 and forms an interference fit, keeping the side pull frame 9 in a fully extended state and preventing accidental retraction due to vehicle shaking during operation. When the item is pushed back in, the second limiting slider 22 slides into the groove near the inner side of the first limiting groove 15 and forms an interference fit, preventing it from sliding out by external force.
[0018] In this embodiment, the front pull frame 10 includes two first front pull frame side strips 23, and two second front pull frame side strips 24 are fixedly connected between the two first front pull frame side strips 23. Each first front pull frame side strip 23 has a second limiting groove 25 on both side walls. Multiple second bearing balls 26 are rotatably mounted on the lower end face of each first front pull frame side strip 23 located between the two second limiting grooves 25. The second bearing balls 26 roll within the corresponding first bearing groove 19, and the second limiting grooves 25 are slidably connected to the corresponding first limiting sliders 20. When it is necessary to take or put an item from the front, the front pull frame 10 is pulled forward. The pull frame 10 and the second bearing ball 26 roll along the first bearing groove 19, causing the front pull frame 10 to extend forward smoothly relative to the side pull frame 9. The first limiting slider 20 slides synchronously in the second limiting groove 25. When the front pull frame 10 is fully pulled out, the first limiting slider 20 slides into the groove near the front end of the second limiting groove 25 and is interference-fitted with it, so that the front pull frame 10 is kept in the pulled-out position, which makes it convenient for nursing staff to directly take medicines, instruments, etc. from the front of the vehicle. When storing, the first limiting slider 20 slides into the groove near the rear end of the second limiting groove 25 and is interference-fitted to prevent the front pull frame 10 from moving forward at will.
[0019] Therefore, the movable tray 11 can be flexibly pulled out to the side or forward according to the actual space conditions, without having to move or rotate the vehicle body due to narrow passages, which can improve nursing efficiency and operational safety in compact medical environments.
