[0021] like Figure 1 and Figure 4As shown, an adjustable chair armrest includes a connecting plate 1 for connecting with a seat, a support plate 2 is slidably provided on the connecting plate 1, a first connecting rod 21 is fixedly provided on the connecting plate 1, a second connecting rod 22 is fixedly provided on the support plate 2 and the second connecting rod 22 is slidably penetrated in the first connecting rod 21, a plurality of threaded holes 23 are opened on the second connecting rod 22, a bolt 24 is provided on the first connecting rod 21 and the bolt 24 passes through the first connecting rod 21 and is threadedly connected with one of the threaded holes 23, the distance between the armrest plate 5 and the seat can be changed by changing the position of the second connecting rod 22 on the first connecting rod 21, and the moved second connecting rod 22 can be locked by the bolt 24 and the threaded hole 23 on the second connecting rod 22.

[0022] like Figure 2 and Figure 4 As shown, a hollow first armrest 3 is slidably provided on the support plate 2, a guide groove 14 is opened on the support plate 2, a roller 15 is rotatably provided on the first armrest 3 and the roller 15 rolls in the guide groove 14, and the cooperation between the roller 15 and the guide groove 14 facilitates the movement of the first armrest 3 on the support plate 2.

[0023] like Figure 1 and Figure 2 As shown, a locking assembly for locking the position of the first armrest 3 is provided on the first armrest 3, and the locking assembly includes a fixed plate 6 with an opening, a first spring 7, a penetration rod 8, a sliding plate 9, a pull rope 10 and an insertion block 11, the fixed plate 6 is fixed in the first armrest 3, the first spring 7 is fixed on the fixed plate 6, the penetration rod 8 is fixedly connected to the first spring 7, the sliding plate 9 is slidably arranged in the first armrest 3 and the sliding plate 9 is fixedly connected to the penetration rod 8, the pull rope 10 is fixed on the sliding plate 9 and the pull rope 10 slides through the fixed plate 6 and toward the outside of the first armrest 3 The plug block 11 is fixedly arranged on the side of the sliding plate 9 away from the pull rope 10, a plurality of insertion holes 12 are opened on the support plate 2 and the plug block 11 is clamped with the insertion hole 12, a fixed pulley 13 is arranged in the first handrail 3, and the pull rope 10 is wound around the fixed pulley 13. The pull rope 10 can be used to disengage the plug block 11 on the sliding plate 9 from the plug block 11 on the support plate 2, so as to facilitate the user to move the first handrail 3. The sliding plate 9 that loses the pulling force of the pull rope 10 can be returned to the initial position through the setting of the first spring 7, so as to facilitate the plug block 11 to be clamped with the plug block 11 again.

[0024] like Figure 1 and Figure 3As shown, a hollow second armrest 4 is vertically slidably penetrated in the first armrest 3, a height adjustment component for adjusting the sliding height of the second armrest 4 is provided in the first armrest 3, the height adjustment component includes a second spring 16, a sliding block 17 and a plurality of fixed blocks 18, a first horizontal slide groove 19 is provided on the first armrest 3, the second spring 16 is fixedly arranged in the first slide groove 19, the sliding block 17 is fixedly connected to the second spring 16 and the sliding block 17 is slidably arranged in the first slide groove 19, a second vertical slide groove 20 is provided on the second armrest 4 and the end of the sliding block 17 is fixedly arranged in the first slide groove 19, The sliding block 17 slides through the second slide groove 20, and the fixed blocks 18 are vertically arranged in the second handrail 4. The top of one end of the sliding block 17 extending into the second handrail 4 abuts against the bottom of one of the fixed blocks 18. An armrest plate 5 is fixed to the end of the second handrail 4 away from the first handrail 3. The sliding block 17 can be disengaged from the abutment with the fixed block 18 by pulling the sliding block 17, so that the user can adjust the height position of the second handrail 4. The sliding block 17 that has lost the pulling force can be returned to the initial position by the setting of the second spring 16, so that the top surface of the sliding block 17 abuts against the bottom surface of the fixed block 18.

[0025] Working principle:

[0026] First, connect the connecting plate 1 to the seat body. When the user needs to adjust the distance between the seat body and the armrest plate 5, the user can rotate the bolt 24 to disconnect it from the threaded hole 23 on the second connecting rod 22, and then move the second connecting rod 22 to a suitable position, and then thread the bolt 24 to the threaded hole 23 on the second connecting rod 22 again.

[0027] When the user needs to change the position of the armrest plate 5, the user pulls the pull rope 10, and the pull rope 10 can make the sliding plate 9 and the plug block 11 gradually move away from the hole 12. When the plug block 11 is disengaged from the hole 12, the user moves the first armrest 3, and the roller 15 on the first armrest 3 can move in the guide groove 14 on the support plate 2. When the first armrest 3 moves to a suitable position, the user releases the pull rope 10, and the sliding plate 9 returns to its initial position under the elastic force of the first spring 7, so that the plug block 11 on the sliding plate 9 is re-engaged with the hole 12 on the support plate 2, thereby locking the position of the first armrest 3 after moving.

[0028] When the user needs to change the height position of the armrest board 5, the user pulls the sliding block 17, and the sliding block 17 can move in the first sliding groove 19 and the second sliding groove 20, so that the top surface of the sliding block 17 loses the abutment relationship with the bottom of the fixed block 18, and then the user moves the position of the second armrest 4 on the first armrest 3 to change the height position of the armrest board 5. When the user moves the armrest board 5 to a suitable height position, the user releases the sliding block 17, and under the action of the second spring 16, the top surface of the sliding block 17 abuts against the bottom surface of the fixed block 18 again, thereby locking the position of the moved second armrest 4 and changing the height position of the armrest board 5.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
