Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a stop bar connecting assembly and an electric bed. Background Technology

[0002] Modern electric beds and smart beds all use mattress guards. Their purpose is to prevent the mattress from sliding towards the feet (foot of the bed) when the back of the electric bed or smart bed is raised. Many existing guards are installed by inserting them into the bed frame. The guard sleeves that fit with the guards are mainly made of plastic. They are usually installed by directly hammering them into the pre-drilled holes in the bed surface. This installation method can easily cause the guard sleeves to become crooked or even fall off, causing unnecessary trouble for customers.

[0003] Chinese patent document CN219742272U discloses a mattress stop device and an electric bed, including a stop, a connecting component, and a fixing component. The fixing component consists of at least two hole sleeves. In use, the hole sleeves are inserted into corresponding countersunk holes on the bed frame. The hole sleeves are made of plastic, silicone, or other materials with a certain degree of elastic deformation. The diameter of the countersunk hole is slightly smaller than the outer diameter of the hole sleeve. By utilizing the deformation of the hole sleeve itself, the hole sleeve is pressed into the countersunk hole, thus creating a tight fit between the hole sleeve and the bed frame. One end of the connecting component is inserted directly into the positioning hole at the top of the hole sleeve, and the other end is connected to the stop. Therefore, when the head of the bed is raised, the stop can be used to restrict the tail end of the mattress, preventing the mattress from slipping or falling off the tail end of the bed frame. In the aforementioned technical solution, the installation method of inserting the sleeve into the countersunk hole by deforming and squeezing it may lead to the sleeve being installed crookedly, resulting in the connection rod and stop rod being installed crookedly. Secondly, when the headboard is raised, the mattress is pressed against the inclined bed board, and under the action of gravity, it tends to slide down the inclined surface. To prevent the mattress from sliding down, the stop rod device needs to withstand the combined force of the mattress's own weight and the user's own weight. This installation method of the sleeve poses a risk of detaching from the bed frame. When using an electric bed, the mattress may slip, posing a certain safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a stop bar connecting assembly and an electric bed, so that the stop bar connecting assembly is stably connected to the bed board, is not easy to fall off, reduces the probability of the mattress slipping off, and improves the safety of the electric bed.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: A stop bar connecting assembly, fixed to a bed board, includes a stop bar sleeve and a nut.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0029] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0030] like Figure 1-7As shown, one embodiment of this utility model relates to a stop bar connection assembly, which is fixed to the bed board 10 and used to connect functional accessories to the bed board 10; the functional accessories include, for example, a stop bar 30 used to restrict the movement of the mattress in the field of electric beds, and a handrail 40 for people with leg disabilities to use for support. The stop lever connecting assembly 20 includes a stop lever sleeve 21, which includes a cylindrical body 210. The body 210 has a positioning hole 212 extending through it along its axis. A flange 211 extends radially outward from the top of the body 210. The lower end face of the flange 211 has multiple first anti-rotation thorns 213. The lower end of the body 210 is a threaded part 214. The outer circumferential surface of the threaded part 214 is provided with an external thread that mates with the nut 23. When the stop lever connecting assembly 20 is fixed to the bed plate 10, the stop lever sleeve 21 passes through the mounting hole 11 on the bed plate 10, the lower end face of the flange 211 abuts against the upper surface of the bed plate 10, the first anti-rotation thorns 213 pierce the upper surface of the bed plate 10, the threaded part 214 protrudes from the lower surface of the bed plate 10, and the nut 23 is threadedly engaged with the threaded part 214 and a preload is applied, thereby locking the stop lever sleeve 21 to the bed plate 10. Preferably, the stop lever sleeve 21 is made of metal to further increase its durability and reduce the risk of breakage due to pressure. The first anti-rotation spike 213, inserted into the upper surface of the bed board 10, circumferentially fixes the stop lever sleeve 21 to the bed board 10, effectively preventing rotation of the stop lever sleeve 21 relative to the bed board 10. The threaded engagement of the nut 23 with the threaded portion 214 of the stop lever sleeve 21 locks the stop lever sleeve 21 to the bed board 10, effectively preventing the stop lever sleeve 21 from axially dislodging from the mounting hole 11 of the bed board 10, thus improving the stability and safety of the connection between the stop lever sleeve 21 and the bed board 10.

[0031] One embodiment relates to a stop lever connection assembly, wherein a first anti-rotation thorn 213 is provided on the lower surface of a flange 211. The first anti-rotation thorn 213 has a tip extending toward the threaded portion 214. When the stop lever sleeve 21 is installed from top to bottom into the mounting hole 11, the tip of the first anti-rotation thorn 213 abuts against the upper surface of the bed plate 10 before the lower surface of the flange 211. Thus, when the nut 23 and the threaded portion 214 are engaged and a preload is applied, the tip penetrates the upper surface of the bed plate 10, increasing the stability of the connection between the stop lever sleeve 21 and the bed plate 10. Preferably, the longitudinal section of the first anti-rotation thorn 213 is an acute-angled triangle; the transverse section of the first anti-rotation thorn 213 is any one of a circle, a strip, or an S-shape. In an exemplary example, the first anti-rotation thorn 213 is generally conical, with its conical apex facing toward the threaded portion 214.

[0032] One embodiment involves a stop lever connection assembly. To further enhance the stability and durability of the connection between the stop lever connection assembly 20 and the bed board 10, a washer 22 is provided between the nut 23 and the lower surface of the bed board 10. The washer 22 has multiple second anti-rotation spikes 221 on its end face facing the lower surface of the bed board 10. When the stop lever connection assembly 20 is fixed to the bed board 10, the second anti-rotation spikes 221 pierce the lower surface of the bed board 10. Preferably, the longitudinal section of the second anti-rotation spike 221 is an acute-angled triangle; the transverse section of the first anti-rotation spike 213 is any one of a circle, a strip, or an S-shape. In an exemplary example, the second anti-rotation spike 221 is generally conical, with its conical apex facing the flange 211. The washer 22 effectively reduces the probability of the nut 23 loosening, further increasing the stability and durability of the connection between the stop lever connection assembly 20 and the bed board 10.

The connecting posts 52 are inserted into the stop bar connecting components 20 on the adjacent sides of the two bed boards 10 to limit the relative displacement of the two electric beds, thereby further increasing the practicality and functionality of the electric bed.

[0037] like Figure 8 As shown, one embodiment of this utility model also provides an electric bed, including a bed board 10 and an armrest 40 connected to the bed board 10. Multiple stop bar connecting assemblies 20 are fixedly installed on the bed board 10, and the inner wall of the positioning hole 212 of the stop bar sleeve 21 is provided with an internal thread 2121. The armrest 40 is detachably and fixedly connected to the bed board 10 through the stop bar connecting assemblies 20. Preferably, a connecting piece 41 is provided between the armrest 40 and the stop bar connecting assemblies 20. One end of the connecting piece 41 is fixed to the stop bar sleeve 21 by a screw 42 engaging with the internal thread 2121 of the positioning hole 212 of the stop bar connecting assembly 20, and the other end of the connecting piece 41 is fixedly connected to the bottom end of the armrest 40 by a screw 42. In some embodiments, the stop bar connecting assembly 20 is disposed on the side or front of the bed board 10 to cooperate with the installation of the armrest 40, thereby assisting the elderly or people with mobility impairments in getting in and out of bed.

[0038] The stop lever connecting assembly provided by this utility model features a first anti-rotation thorn that penetrates the upper surface of the bed board, circumferentially fixing the stop lever sleeve to the bed board and effectively preventing the stop lever sleeve from rotating relative to the bed board. The threaded engagement between the nut and the threaded portion of the stop lever sleeve locks the stop lever sleeve to the bed board, effectively preventing the stop lever sleeve from axially dislodging from the mounting hole of the bed board, thus improving the stability and safety of the connection between the stop lever sleeve and the bed board. In particular, the internal thread of the positioning hole of the stop lever sleeve facilitates the installation of handrails on the side or front of the bed board, increasing convenience for people with mobility impairments when getting in and out of bed and enhancing the practicality of the stop lever connecting assembly.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
