[0028] For the convenience of explanation, in this embodiment, each direction is as follows Figure 1 shown.

[0029] In the foldable bedside armrest provided by the utility model, the base 1 and the armrest assembly 2 are not a fixed structure, and the base 1 and the armrest assembly 2 are connected by an adjustment assembly 3. Specifically, an adjustment plate 31 in the adjustment assembly 3 is connected to the base 1, and the armrest assembly 2 is rotatably connected to the adjustment plate 31. Therefore, a rotatable connection between the armrest assembly 2 and the base 1 can be achieved, that is, the angle between the armrest assembly 2 and the base 1 can be adjusted, so that the entire bedside armrest can be stored, and the storage is very convenient. More specifically, when storing, the adjustment pin 33 is moved away from the locking hole 311, and the armrest assembly 2 can be rotated for storage. During normal use, the armrest assembly 2 is rotated to a vertical state, and the adjustment pin 33 is provided on the armrest assembly 2. The elastic member 32 can drive the adjustment pin 33 to be plugged into the locking hole 311. By plugging the adjustment pin 33 into the locking hole 311, the position of the armrest assembly 2 can be fixed. During normal use, the armrest assembly 2 itself can be prevented from rotating, thereby improving the supporting stability of the armrest assembly 2 and improving the safety of the entire foldable bedside armrest during use. While improving the convenience of storage, it also ensures the safety of use.

[0030] In some embodiments, the adjustment assembly 3 also includes an adjustment sleeve 34, which is disposed on the armrest longitudinal rod 21 and passes through the armrest longitudinal rod 21. One end of the elastic member 32 is connected to the adjustment sleeve 34, and the other end of the elastic member 32 is connected to the adjustment pin 33. By setting the adjustment sleeve 34, it is convenient to install the elastic member 32 and the adjustment pin 33, and it is also convenient for the adjustment pin 33 to move left and right more stably, so that it can be inserted into or leave the locking hole 311 more accurately.

[0031] In some embodiments, the armrest longitudinal rod 21 is provided with a mounting hole, and the adjusting sleeve 34 is inserted into the mounting hole. The outer shape of the adjusting sleeve 34 is stepped, and the outer diameter of the end of the adjusting sleeve 34 close to the adjusting plate 31 is larger than the inner diameter of the mounting hole. Specifically, there is an interference fit between the adjusting sleeve 34 and the mounting hole, and the adjusting sleeve 34 can be stably installed in the mounting hole. Designing the outer shape of the adjusting sleeve 34 to be stepped can better position the adjusting sleeve 34 and more conveniently install the adjusting sleeve 34 in the mounting hole.

[0032] In some embodiments, the interior of the adjusting sleeve 34 is provided with a first adjusting hole 341 and a second adjusting hole 342 which are connected to each other. The inner diameter of the first adjusting hole 341 is larger than the inner diameter of the second adjusting hole 342. The adjusting pin 33 has an adjusting portion 331 and a plug-in portion 332. The outer diameter of the plug-in portion 332 is larger than the outer diameter of the adjusting portion 331. The outer diameter of the plug-in portion 332 is adapted to the inner diameter of the first adjusting hole 341. The outer diameter of the adjusting portion 331 is adapted to the inner diameter of the second adjusting hole 342. The elastic member 32 is provided in the first adjusting hole 341. The two ends of the elastic member 32 are respectively abutted against the adjusting sleeve 34 and the plug-in portion 332.

The first adjustment hole 341 and the second adjustment hole 342 can form a step-like structure. The elastic member 32 is arranged at the step-like structure in the adjustment sleeve 34, which can better drive the plug-in portion 332 to be plugged into the locking hole 311, and can better fix the position of the armrest assembly 2, thereby preventing the armrest assembly 2 from rotating itself, improving the support stability of the armrest assembly 2, and improving the safety of the entire foldable bedside armrest when in use.

[0034] In some embodiments, the elastic member 32 is a spring, and the elastic member 32 is sleeved on the adjusting portion 331. The outer diameter of the elastic member 32 is larger than the inner diameter of the second adjusting hole 342, and the outer diameter of the elastic member 32 is smaller than the outer diameter of the plug-in portion 332. The spring can better drive the plug-in portion 332 to be plugged into the locking hole 311, and can better fix the position of the armrest assembly 2, thereby preventing the armrest assembly 2 from rotating itself, improving the supporting stability of the armrest assembly 2, and improving the safety of the entire foldable bedside armrest when in use.

[0035] In some embodiments, the foldable bedside armrest also includes a connecting piece 4. The number of adjustment components 3 is two. The two adjustment components 3 are symmetrically arranged on both sides of the armrest component 2. The two ends of the connecting piece 4 are respectively connected to the two adjustment pins 33. The connecting piece 4 is a flexible belt-like structure. The connecting piece 4 can be deformed to drive the two adjustment pins 33 to approach each other and leave the locking hole 311. By setting up two adjustment components 3, the armrest component 2 can be better stored, and the position of the armrest component 2 can be better fixed. By setting up a connecting piece 4 with a flexible belt-like structure, such as a rope, the two adjustment pins 33 can be simultaneously pulled out of the two locking holes 311 by pulling the connecting piece 4, and then stored. The operation is simpler and the storage is more convenient.

[0036] In some embodiments, the connecting member 4 is a rubber member. The connecting member 4 is a belt-shaped structure made of rubber and has a certain deformation ability and recovery ability. It can more conveniently pull the two adjustment pins 33, which is more convenient to use.

[0037] In some embodiments, the armrest assembly 2 also includes an armrest shaft 22, and the number of armrest longitudinal rods 21 is two. The two ends of the armrest shaft 22 are respectively fixedly connected to the two armrest longitudinal rods 21, and the two ends of the armrest shaft 22 are respectively rotatably connected to the two adjustment plates 31, which can better rotate the armrest longitudinal rods 21 and make storage more convenient.

[0038] In some embodiments, the armrest assembly 2 further includes an armrest cross bar 23, the two ends of which are respectively connected to the two armrest longitudinal bars 21. The armrest cross bar 23 facilitates the user to apply force, making it more convenient to use.

[0039] In some embodiments, the foldable bedside armrest also includes a reinforcing tube 5, and both ends of the reinforcing tube 5 are respectively connected to the two adjustment plates 31. By providing the reinforcing tube 5, the overall structural strength can be improved and the stability during use can be improved.
