[0001] This utility model relates to the field of medical device technology, and in particular to a telescopic rocker with precise angle adjustment ruler. Background Technology
[0002] In medical rehabilitation settings, the nursing needs of postoperative patients are paramount. For example, if the angle of the rocking bed is not appropriate when a patient is eating, it may lead to swallowing difficulties or even choking. When using a lower limb function bed, precisely adjusting the bed elevation angle plays a crucial role in promoting blood circulation in the lower limbs and assisting rehabilitation training. In these cases, ordinary rocking bed angle adjustment methods are insufficient, thus requiring a precise rocking bed angle adjustment ruler.
[0003] However, existing angle adjustment rulers still have the following technical problems in practical use:
[0004] Most existing adjustment rulers may not have folding or telescopic extension functions, taking up a lot of space when stored, making them inconvenient to store and carry in space-constrained settings such as hospitals and home care facilities. If the rocker has a special size, existing adjustment rulers may not be able to flexibly adjust the length, making it difficult to ensure a tight fit with the bed frame, thus affecting the accuracy of angle measurement. They may only be compatible with rockers of specific sizes or shapes, making them unsuitable for small children's beds, large double beds, or irregularly shaped beds, failing to meet diverse usage needs. Furthermore, they lack effective fixing devices, and the adjustment ruler may easily wobble and shift during rocker angle adjustment, affecting the accuracy and stability of angle adjustment.
[0005] In response to this technical problem, this application proposes a telescopic rocker angle precision adjustment ruler. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a telescopic rocker angle precision adjustment ruler. This ruler allows for space saving and easy storage and carrying by rotating the movable plate to overlap with the fixed plate when stored, retracting the limiting plate, and shrinking the extension plate and movable plate. When in use, the limiting plate can attract and clamp bed bodies of different sizes, greatly expanding the applicability range and surpassing existing adjustment rulers.

Detailed Implementation
[0026] 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.
[0027] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a telescopic rocker angle precision adjustment ruler, comprising a fixed plate 1, an angle groove 2 at the front right end of the fixed plate 1, a through groove 3 at the front right end of the fixed plate 1, a movable plate 5 connected to the through groove 3 via a movable component 4, a display groove 6 at the front left end of the movable plate 5, an extension plate 7 rotatably connected to the front right end of the movable plate 5, a sliding groove 8 at the front of the extension plate 7, a second sliding groove 10 at the middle of the rear side of the inner wall of the sliding groove 8, an extension plate 9 slidably connected to the inner wall of the sliding groove 8, the extension plate 9 being connected to the sliding groove 10 via a positioning component 11, a third sliding groove 12 at the rear right end of the extension plate 9, a limit block 20 slidably connected to the inner wall of the third sliding groove 12, a tension spring 21 fixedly connected to the bottom of the limit block 20, the bottom end of the tension spring 21 being fixedly connected to the bottom side of the inner wall of the third sliding groove 12, and a limit plate 13 rotatably connected to the rear bottom end of the fixed plate 1.
[0028] Specifically, the angle groove 2 features a clear and intuitive scale marking design, allowing users to quickly and accurately read the rocker angle value even in low-light conditions. This greatly improves the convenience and efficiency of operation, avoiding adjustments due to incorrect angle readings. The movable component 4 has a compact structure and is easy to operate. Users can easily rotate the tensioning bolt 401 to flexibly rotate the movable plate 5 to form an angle with the fixed plate 1. When no adjustment is needed, rotating the movable plate 5 to align it with the fixed plate 1 and then tightening the limiting bolt 402 achieves folding and storage. This adjustment method not only quickly adapts to various sizes of rockers but also significantly shortens the length of the adjustment ruler during storage, effectively saving storage space. It is convenient to store and carry in scenarios such as hospitals and home care.
[0029] Extension plates 7 and 9, through the ingenious cooperation of slide rails 8 and 10, achieve length adjustment, precisely matching complex and varied usage scenarios. For example, on some specially shaped or irregularly sized rockers, by finely adjusting the length of the extension plates, it can ensure that the adjusting ruler fits tightly with the bed frame, thus providing a more stable and reliable foundation for angle measurement and significantly improving the accuracy and stability of angle adjustment. The limiting block 20, which is slidably connected inside slide rail 12, can fit against the surface of the top side of the bed frame. Together with tension spring 21, it provides a stable initial fixing point for the adjusting ruler during the rocker angle adjustment process, effectively reducing the shaking and displacement of the adjusting ruler. Combined with the clamping action of limiting plates 13 and 18, it further ensures the stability of the adjusting ruler during use, making angle adjustment more accurate and reliable.
[0030] Reference Figure 2 , Figure 3 and Figure 5A limiting groove 15 is formed at the rear end of the top side of the fixed plate 1. A limiting block 16 is slidably connected to the inner wall of the limiting groove 15. A connecting block 17 is fixedly connected to the top of the limiting block 16. A limiting plate 2 18 is rotatably connected to the top rear side of the connecting block 17. A tension spring 19 is fixedly connected to the bottom of the limiting block 16. The bottom end of the tension spring 19 is fixedly connected to the bottom side of the inner wall of the limiting groove 15. The movable component 4 includes a plug 401 and a through groove 2 403. The plug 401 is detachably connected to the inner wall of the through groove 1 3. The outer front end of the plug 401 passes through the through groove 1 3 and is threadedly connected to a limiting plug 402. The through groove 2 403 is formed at the left front end of the movable plate 5. The middle outer end of the plug 401 is detachably connected to the through groove 2 403. The positioning component 11 includes a screw hole 1101, which is located on the rear left side of the extension plate 2 9. A positioning bolt 1102 is threaded onto the inner wall of the screw hole 1101, and the outer middle end of the positioning bolt 1102 is detachably connected to the inner wall of the slide groove 2 10. Magnetic adhesive strips 14 are fixedly connected to the adjacent sides of the limiting plate 13 and the limiting plate 2 18. The slide groove 2 10 is a long strip shape from left to right.
[0031] Specifically, limiting plates 13 and 18 can not only be magnetically attached to the bed frame via the magnetic adhesive 14, but also be rotated to clamp different bed frame sizes, greatly expanding the applicability of the angle adjustment ruler. Whether it's a small children's bed, a large double bed, or an irregularly shaped special bed frame, a suitable fixing method can be found, meeting diverse usage needs. When the angle adjustment ruler is not in use, limiting plates 13 and 18 can be rotated and folded up to fit against the fixing plate 1, reducing the overall size. At the same time, extension plate 9 and movable plate 5 can also be retracted to their shortest length for easy storage in confined spaces. Moreover, due to the sturdy structure of the adjustment ruler, it is not easily damaged by shaking or collisions during transport, making it suitable for use in various scenarios.
[0032] Working principle: During operation, the movable component 4 firstly uses the plug 401 to cooperate with the through slot 3 and through slot 403 to rotate the movable plate 5 and the fixed plate 1 to unfold the adjustment ruler. When not in use, it can be folded for storage. The angle slot 2 reads the angle value. The extension plate 7 and extension plate 9 are adjusted in length by means of the slide 8 and slide 10 to adapt to irregular rocking beds. The limiting block 20 is attached to the top side surface of the bed and cooperates with the tension spring 21 to provide the initial fixing point. The limiting plate 13 and limiting plate 28 are attached to the bed by the magnetic sticker 14 and can also rotate to clamp different sizes of bed. The limiting block 16 and tension spring 19 allow the limiting plate 28 to flexibly adjust its position. The positioning plug 1102 of the positioning component 11 cooperates with the screw hole 1101 and the slide 10 to fix the extension plate 29. Finally, it can achieve functions such as precise adjustment of the rocking bed angle, stable fit to the bed, and convenient storage and carrying.
[0033] 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.
