Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0039] The utility model provides an adjustable nursing bed guardrail, comprising: a bed board 1, bed legs 3 are fixedly installed at the four corners of the lower side of the bed board 1, lower brackets 3 are installed on both sides of the bed board 1, multiple first connecting plates 4 are fixedly connected to the upper sides of the lower brackets 3, the multiple first connecting plates 4 are rotatably connected to the rotating plates 5 through pins, the upper sides of the rotating plates 5 are rotatably connected to the second connecting plates 6 through pins, the upper sides of the multiple second connecting plates 6 are fixedly connected to the upper brackets 7, a locking mechanism 8 is provided on the right side of the upper bracket 7, and the lower brackets 3 are provided with quick-release mechanisms 9.

[0040] This design, through the quick-release mechanism 9, makes the installation and disassembly process between the bed body and the guardrail quick and convenient. This design not only greatly saves the user's time and energy, but also significantly improves the applicability and practicality of the utility model, meeting the needs and scenarios of different users.

[0041] The quick-release mechanism 9 can quickly assemble and disassemble the guardrail and the bed. When comprehensive protection is required for both sides of the bed, the user only needs to pull up the upper bracket 7. As the upper bracket 7 rises steadily to the specified height, the built-in locking mechanism 8 will accurately lock the inclination angle of the rotating plate 5 to ensure the stability and safety of the guardrail, and effectively avoid the risk of falling due to negligence when the user uses the protective bed. When the user needs to get on and off the bed, by simply operating the locking mechanism 8, the user can easily unlock the inclination angle of the rotating plate 5, and then press down the upper bracket 7 to quickly complete the storage of the guardrail.

[0042] In this embodiment, the locking mechanism 8 includes a cavity block 801, which is fixedly connected to the underside of the upper bracket 7. A first spring 802 is fixedly connected to the inner wall of the upper side of the cavity block 801, and a first clamping block 803 is fixedly connected to the underside of the first spring 802. A second through-slot 804 is defined on the outer surface of the cavity block 801, which is compatible with the first clamping block 803. A first connecting rod 805 is fixedly connected to the right side of the first clamping block 803. The first connecting rod 805 extends to the outside of the cavity block 801 through a third through-slot 806 and is slidably connected to the third through-slot 806. A fixing block 807 is fixedly connected to the right side of the rightmost rotating plate 5, and a notch 808 is defined on the upper side of the fixing block 807, which is compatible with the first clamping block 803.

[0043] With this design, due to the elastic action of the first spring 802, the first card block 803 will naturally move downward. At the same time, due to the setting of the first connecting rod 805 and the third through slot 806, it is ensured that the first card block 803 has a clear limit during the descending process to prevent it from excessively descending. When the upper bracket 7 drives the five rotating plates 5 to perform the ascending operation, the first card block 803 will first pass through the inclined surface on the right side of the fixed block 807, and then accurately snap into the notch 808 inside the fixed block 807, thereby achieving a firm locking of the five rotating plates 5; if it is necessary to descend or store the rotating plate 5, the operation process is also simple and quick. First, gently pull the first connecting rod 805 upward to disengage the first card block 803 from the notch 808, and then apply pressure to the upper bracket 7 to the lower right, so that the rotating plate 5 can be quickly stored and lowered.

[0044] In this embodiment, the quick-release mechanism 9 includes a push rod 901. A first through-slot 301 is defined within the lower bracket 3, adapted to fit within the push rod 901. A second slider 902 is fixedly connected to the outer surface of the push rod 901, which is slidably connected to the first through-slot 301. A second spring 903 is fixedly connected to the left side of the second slider 902, and a second clamping block 904 is fixedly connected to the end of the second spring 903 away from the second slider 902. A fixed ring block 905 is fixedly connected to the outer surface of the push rod 901. A movable member 906 is provided on the left side of the fixed ring block 905. The movable member 906 is slidably connected to the push rod 901. A semicircular block 907 is connected to the push rod 901, and a third spring 908 is fixedly connected to the middle of the semicircular block 907 and the movable member 906. The bed board 1 has a first chute 101 formed inside thereof, adapted to fit within the semicircular block 907. A placement slot 102 is formed above the first chute 101. The first chute 101 and placement slot 102 are in communication. A fixed plate 909 is fixedly connected to the placement slot 102. A second connecting rod 910 is slidably connected to the fixed plate 909. A limit plate 911 is fixedly connected to the upper side of the second connecting rod 910, and a third clamping block 912 is fixedly connected to the lower side of the second connecting rod 910. A fourth spring 913 is fixedly connected between the third clamping block 912 and the middle portion of the fixed plate 909. The third clamping block 912 fits within the gap between the movable member 906 and the middle portion of the semicircular block 907.

[0045] With this design, when the guardrail and the bed are to be quickly installed, the semicircular blocks 907 on both sides of the lower bracket 3 are first made to enter the first slide grooves 101 on both sides of the bed. When the semicircular blocks 907 contact the third clamping blocks 912, because the semicircular blocks 907 are semicircular, they will push the third clamping blocks 912 upwards, and then the third clamping blocks 912 will be stuck in the gap between the movable part 906 and the middle part of the semicircular blocks 907, thereby locking the guardrail. When the guardrail and the bed are to be quickly disassembled, the push rod 901 is first pushed to the left, and the push rod 901 will drive the movable part 906 to be disassembled. The movable member 906 moves to the left. Since the movable member 906 is approximately rhombus-shaped, when the movable member 906 moves to the left, the third clamping block 912 will slide to the right side of the movable member 906, and then the guardrail will be pulled outward. The third clamping block 912 will drive the movable member 906 to the right to compress the third spring 908. The movable member 906 and the semicircular block 907 will conflict with each other, and the guardrail will continue to be pulled outward. The third clamping block 912 can slide through the outer surface of the movable member 906 connected to the semicircular block 907 and away from the semicircular block 907, so that the guardrails on both sides can be disassembled.

[0046] Pulleys are installed on the bottom of the bed legs 3. Designed like this, the entirety of the bed is easy to move and can be moved to different areas for use.

[0047] The specific method of use is as follows: first, the guardrail and the bed body are quickly installed through the quick-release mechanism 9, which greatly improves the convenience of operation. Secondly, the locking mechanism 8 can accurately lock the tilt angle of the rotating plate 5 to ensure the stability and safety of the guardrail, which can effectively avoid the risk of falling due to negligence when the user is using the protective bed. When the user needs to get on and off the bed, the user can easily unlock the tilt angle of the rotating plate 5 by simply operating the locking mechanism 8, and then press down the upper bracket 7 to quickly complete the storage of the guardrail. When the guardrail and the bed body need to be quickly disassembled, when the guardrail and the bed body need to be quickly disassembled, First, push the push rod 901 to the left, and the push rod 901 will drive the movable part 906 to move to the left. Because the movable part 906 is approximately rhombus-shaped, when the movable part 906 moves to the left, the third clamping block 912 will slide to the right side of the movable part 906. Then, pull the guardrail outward, and the third clamping block 912 will drive the movable part 906 to the right to compress the third spring 908. The movable part 906 and the semicircular block 907 will conflict with each other. Continue to pull the guardrail outward, and the third clamping block 912 can slide through the outer surface connected to the semicircular block 907 of the movable part 906 and away from the semicircular block 907, so that the guardrails on both sides can be disassembled.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
