[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1-8 A folding bedside armrest includes a support assembly 10, an armrest assembly 20, and a locking assembly 30. The support assembly 10 is provided with a first connecting member 110 on the left and right sides, and the armrest assembly 20 is provided with a second connecting member 210 on the left and right sides. The first connecting member 110 is rotatably connected to the second connecting member 210. The locking assembly 30 includes a locking pin 310 that moves left and right relative to the first connecting member 110. The second connecting member 210 is provided with a locking groove 211. The locking pin 310 and the first connecting member 110 are connected to an elastic element 320.

[0026] The elastic element 320 is configured as follows: the elastic element 320 applies a force to the locking pin 310 so that the locking pin 310 is inserted into the locking groove 211;

[0027] The locking assembly 30 further includes a soft pull member 330 , the left and right ends of which are respectively connected to the left and right locking pins 310 .

[0028] When the armrest assembly 20 needs to be folded and stored relative to the support assembly 10, the soft pull member 330 is pulled to drive the locking pin 310 to disengage from the locking groove 211 to complete the unlocking. After unlocking, the first connecting member 110 and the second connecting member 210 can rotate relative to each other for easy folding and storage.

[0029] See also Figure 4 The first connecting member 110 is provided with a transverse channel 111 which is interconnected with the locking groove 211 , and the locking pin 310 is arranged in the transverse channel 111 to move left and right.

[0030] See also Figure 4, a connecting hole 112 is provided on the wall surface of the first connecting member 110 facing the other first connecting member 110, which is interconnected with the transverse channel 111. The locking pin 310 includes a locking column 311 slidably arranged in the transverse channel 111. The locking column 311 is connected to a connecting column 312, and the connecting column 312 extends outward through the connecting hole 112. The elastic element 320 is sleeved on the connecting column 312 and is respectively connected to the locking column 311 and the inner wall of the transverse channel 111; the soft pull member 330 is connected to the connecting column 312. In this embodiment, the aperture of the connecting hole 112 is smaller than that of the transverse channel 111. This design can prevent the locking column 311 from detaching from the connecting hole 112 during the transverse unlocking process. In the actual unlocking process, pulling the soft pull member 330 can drive the connecting column 312 to move, thereby driving the locking column 311 to detach from the transverse channel 111 to achieve unlocking.

[0031] See also Figure 4 The left and right ends of the soft pull member 330 are provided with connecting rings 340, and the connecting rings 340 are sleeved on the connecting column 312. The connecting column 312 is threadedly connected with a locking nut 350, and the connecting ring 340 is located between the first connecting member 110 and the locking nut 350.

[0032] Furthermore, the soft pull member 330 is a steel wire rope.

[0033] See also Figure 5 The support assembly 10 includes support rods 120 spaced apart on the left and right sides, and a stabilizing rod 130 is connected to the left and right support rods 120. A first connecting pipe 113 is provided on the first connecting member 110, and the first connecting pipe 113 is fixedly connected to the support rods 120.

[0034] See also Figure 5 The armrest assembly 20 includes an armrest body 220 , and the armrest body 220 is respectively provided with a second connecting pipe 230 extending downward, and the second connecting pipe 210 is provided with a third connecting pipe 212 fixedly connected to the second connecting pipe 230 .

[0035] See also Figure 1 The support assembly 10 is connected to a connecting frame 40 fixed to the bed body. The function of the connecting frame 40 is to connect the bed body and play a fixing role.
