The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

As shown in fig. 1 to 10, an adjustable armrest support device according to an embodiment of the present invention includes a support 1, an armrest assembly 2, and an adjustment assembly 3; a mounting seat 11 is formed by the bulge on the support 1; the armrest component 2 comprises an armrest arm 21 and a ratchet wheel 22, wherein one end of the armrest arm 21 forms a supporting portion 211, the ratchet wheel 22 is fixedly connected with the other end of the armrest arm 21, the ratchet wheel 22 is rotatably arranged on the mounting seat 11, a tooth groove 221 is formed in the ratchet wheel 22, and a ratchet wheel protruding point 222 is arranged on the side portion of the ratchet wheel 22.

The adjusting component 3 comprises a cam 31, a pawl 32 and an elastic part 33, the cam 31 and the ratchet 22 are coaxially arranged, the side part of the cam 31 is provided with a track limiting groove 311 matched with the ratchet salient point 222, the cam 31 is driven to rotate by the rotating ratchet salient point 222, and the bottom surface of the cam 31 comprises an arc surface 312 and an inclined surface 313 integrally connected with the arc surface 312; the pawl 32 is rotatably mounted on the mounting seat 11, and the elastic member 33 is connected to the pawl 32 and drives the pawl 32 to rotate away from the support 1, so that the pawl 32 is tightly abutted against the bottom surface of the cam 31 or the pawl 32 is driven to be clamped into the tooth groove 221 of the ratchet wheel 22.

When the supporting is needed, the hand of the user applies force to the supporting portion 211 to drive the armrest arm 21 to rotate on the mounting seat 11 through the ratchet 22, the pawl 32 is initially tightly abutted against the arc surface 312 of the cam 31, when the armrest arm 21 rotates, the ratchet salient point 222 rotates to drive the cam 31 to rotate through the track limiting groove 311, when the supporting portion 211 rotates to the horizontal state, the pawl 32 is separated from the arc surface 312, the elastic member 33 drives the pawl 32 to be clamped into the tooth groove 221 to limit the armrest arm 21 to continuously descend, so that the supporting portion 211 of the armrest arm 21 can be supported, after the user finishes supporting, the force can be applied to the armrest arm 21 to drive the armrest arm 21 to reversely rotate, when the armrest arm 21 reversely rotates, the ratchet salient point 222 reversely rotates to drive the cam 31 to reversely rotate through the track limiting groove 311, so that the pawl 32 is separated from the tooth groove 221 and is abutted against the arc surface 312 again, so that the armrest arm 21 is in a vertical state as a whole, thereby reducing the occupied space.

Optionally, one end of the track limiting groove 311 is a first limiting point 3111, the other end of the track limiting groove 311 is a second limiting point 3112, and the ratchet bump 222 can swing back and forth between the first limiting point 3111 and the second limiting point 3112. The ratchet wheel 22 has a plurality of tooth slots 221 and the pawls 32 can be snapped into different tooth slots 221.

In this example, as shown in fig. 2, three tooth slots 221 are provided, which are a first tooth slot 2211, a second tooth slot 2212 and a third tooth slot 2213, in an initial state, the ratchet salient point 222 abuts against the first limit point 3111, when the supporting portion 211 rotates to a horizontal state, the ratchet salient point 222 moves from the first limit point 3111 to the second limit point 3112, the pawl 32 abuts against the arc surface 312 of the cam 31, the cam 31 prevents the pawl 32 from being clamped into the first tooth slot 2211 and the second tooth slot 2212, after the ratchet salient point 222 moves to the second limit point 3112, the ratchet salient point 222 continues to move, the cam 31 is driven by the second limit point 3112 to rotate, so that the pawl 32 is separated from the arc surface 312, the elastic member 33 prevents the pawl 32 from being clamped into the third tooth slot 2213, so as to limit the armrest arm 21 from continuing to descend, so that the supporting portion 211 of the armrest arm 21 can support, and at this time, the supporting portion 211 is in a horizontal state.

After the user finishes supporting, force is applied to the armrest arm 21, the armrest arm 21 is driven to rotate reversely, when the armrest arm 21 rotates reversely, the ratchet salient point 222 moves to the first limit point 3111 from the second limit point 3112, when the ratchet salient point 222 does not move to the first limit point 3111, the pawl 32 is clamped into the second tooth groove 2212, the second tooth groove 2212 prevents the armrest arm 21 from sliding downwards, so that a person with a higher height can support the armrest arm, the ratchet salient point 222 continues to move, the pawl 32 is clamped into the third tooth groove 2213, the third tooth groove 2213 prevents the armrest arm 21 from sliding downwards, and therefore a person with a higher height can support the armrest arm conveniently. Finally, when the ratchet salient point 222 moves to the first limit point 3111, the cam 31 is driven to rotate by the first limit point 3111, so that the initial position is recovered, and the next use is facilitated.

In this example, the adjustable armrest supporting device may be disposed on one side of the wall, so that after use, when the arm support 21 is wholly in a vertical state, the arm support 21 may abut against the wall.

Mounting holes may be provided in the armrest arm 21 and the armrest support 4, and screws may be sequentially inserted through the mounting holes of the armrest arm 21 and the mounting holes of the armrest support 4 to securely connect the armrest support 4 to the armrest arm 21. The armrest support 4 and the first rotating shaft 112 can be rigidly connected through a key 41, and the first rotating shaft 112 and the ratchet wheel 22 can be rigidly connected through a key 41.

As an example, the mounting seat 11 is provided with a first connection hole 111, the first connection hole 111 is provided with a first rotation shaft 112, and the first rotation shaft 112 passes through the mounting seat 11, the ratchet wheel 22, the cam 31 and the armrest support 4 so that the armrest arm 21 can be rotatably disposed on the mounting seat 11. The first connection holes 111 may be two, the ratchet 22 may be two, and the first rotating shaft 112 passes through one of the first connection holes 111, one of the ratchet 22 and the cam 31 and then is connected to the other ratchet 22 and the other first connection hole 111.

As an example, a second connection hole 113 is formed on the mounting base 11, a second rotation shaft 114 is formed on the second connection hole 113, and the second rotation shaft 114 passes through the mounting base 11 and the pawl 32 so that the pawl 32 can be rotatably disposed on the mounting base 11. The number of the second connecting holes 113 may be two, the number of the pawls 32 may be two, and the second rotating shaft 114 passes through one of the second connecting holes 113, and one of the pawls 32 is connected to the other pawl 32 and the other second connecting hole 113.

In this example, the elastic member 33 is a torsion spring, one side of the torsion spring abuts against the surface of the support 1, and the other side of the torsion spring abuts against the bottom wall of the pawl 32. The pawl 32 is provided with a pawl salient point 321, and the pawl salient point 321 penetrates through the middle of the torsion spring to limit the torsion spring. The spring provides a spring force urging pawl 32 away from holder 1, thereby urging pawl 32 to rotate away from holder 1 to tighten pawl 32 against the bottom surface of cam 31 or urging pawl 32 to snap into tooth slot 221 of ratchet 22.
