[0022] like Figures 1-6 As shown, this utility model addresses the problem of high operating costs caused by the need for additional locking mechanisms in existing movable chair armrest structures by providing the following technical solution: An armrest structure for a hospital bed includes an armrest bracket 1, which is disposed on one side of the bed and supports the entire armrest structure; a connecting rod 2, which is fixedly disposed on the outer middle of the armrest bracket 1, the connecting rod 2 being horizontally arranged, and both ends of the connecting rod 2 being hinged to first armrest support rods 3, with connecting pins 4 fixedly disposed on the outer side wall of the connecting rod 2; and a second armrest support rod 5, which is mounted on the two first armrest support rods 3. The top of the first handrail support rod 3 provides the main support function for the handrail. A connecting block 6 is detachably installed on the second handrail support rod 5, which is located directly above the first handrail support rod 3. The lower end of the connecting block 6 is hinged to the first handrail support rod 3. A sliding plate 7 is movably installed on the outside of the connecting rod 2 to adjust the state of the handrail. One end of the sliding plate 7 is connected to the first handrail support rod 3. A guide groove 8 is provided on the sliding plate 7. The connecting pin 4 extends into the guide groove 8 and slides in cooperation with the guide groove 8. No additional locking mechanism is required, which simplifies the operation steps and reduces manufacturing and maintenance costs.

[0023] Specifically, a sleeve 31 is provided at the bottom of the first handrail support rod 3. The sleeve 31 is connected to the connecting rod 2 through the first rotating shaft 32 to realize the rotation function of the first handrail support rod 3. A flat connecting part 33 is provided at the top of the first handrail support rod 3 for easy installation.

[0024] In this embodiment, as Figure 5 As shown, the top of the connecting block 6 is connected to the second handrail support rod 5 by fasteners arranged side by side, and the bottom of the connecting block 6 is provided with an installation groove 61 that matches the connecting part 33. The structure is simple and easy to process.

[0025] In this embodiment, as Figure 1 As shown, a second rotating shaft 62 is threaded through the bottom of the connecting block 6, and the second rotating shaft 62 is rotatably connected to the connecting part 33. The structure is simple and easy to install.

[0026] In this embodiment, as Figure 6As shown, the guide slot 8 includes a clamping groove 81 arranged on the side wall of the sliding plate 7, when the connecting pin 4 is located in the clamping groove 81, the handrail structure is locked, the bottom of the clamping groove 81 is provided with a first inclined sliding groove 82, one side of the first inclined sliding groove 82 is provided with a smooth groove 83, one side of the smooth groove 83 is provided with a second inclined sliding groove 84, one side of the second inclined sliding groove 84 is provided with a third inclined sliding groove 85, to realize the opening and locking of the handrail structure.

[0027] In this embodiment, as shown in the figure, Figure 1 As shown, the two ends of the second handrail support rod 5 are provided with plugs 9 to protect the end of the second handrail support rod 5.

[0028] In this embodiment, as shown in the figure, Figure 1 As shown, during installation, the handrail bracket 1 and the connecting rod 2 are made of square tubes, the first handrail support rod 31 is made of a hollow circular tube, the sliding plate 7 is made of a stainless steel plate, and the second handrail support rod 5 is made of a semicircular aluminum tube. The handrail bracket 1 is fixed on one side of the bed body to ensure stable connection with the bed body. The connecting rod 2 is horizontally installed on the outer middle part of the handrail bracket 1 and is fixed by bolts or welding. The first handrail support rod 3 is installed on both ends of the connecting rod 2. The bottom of the first handrail support rod 3 is hinged to the connecting rod 2 through the sleeve 31 and the first rotating shaft 32 to ensure that the first handrail support rod 3 can rotate around the first rotating shaft 32. The connecting block 6 is installed on the second handrail support rod 5. The top of the connecting block 6 is fixed to the second handrail support rod 5 by fasteners. The installation slot 61 of the connecting block 6 is connected to the connecting part 33 of the first handrail support rod 3, and the second rotating shaft 62 is used for hinging. One end of the sliding plate 7 is connected to the first handrail support rod 3. The connecting pin 4 on the connecting rod 2 is inserted into the guide slot 8 to ensure that the connecting pin 4 can slide in the guide slot 8.

[0029] In this embodiment, as shown in the figure, Figure 1 As shown, during use, the user holds the second handrail support rod 5 and moves it upward. The second handrail support rod 5 drives the first handrail support rod 3 to rotate through the connecting block 6. The first handrail support rod 3 rotates around the connecting rod 2 to a vertical state through the sleeve 31 and the first rotating shaft 32. The sliding plate 7 slides with the movement of the first handrail support rod 3. The connecting pin 4 slides in the guide slot 8 through the third inclined sliding groove 85, the second inclined sliding groove 84, the smooth groove 83, and the first inclined sliding groove 82. When the first handrail support rod 3 is adjusted to a vertical position, the connecting pin 4 stays in the clamping groove 81 of the guide slot 8, and the handrail structure is locked.

[0030] In this embodiment, as shown in the figure, Figure 3 As shown, when the handrail needs to be flat, the user lifts the sliding plate 7 slightly, so that the connecting pin 4 is located in the first inclined sliding groove 82. The user holds the second handrail support rod 5 and moves it. The connecting pin 4 slides in the guide slot 8 until the second handrail support rod 5 is in a flat state.
