[0018] The present utility model will be further described below with reference to the accompanying drawings.
[0019] According toFigures 1-4 As shown: The present utility model provides an office chair with a liftable armrest, which includes a chair main body 1. A support frame 4 is fixedly connected below the chair main body 1, and a universal wheel 5 is connected below the support frame 4, which can ensure the flexibility of the movement of the chair main body 1.
[0020] Support plates 2 are fixedly connected to both sides of the chair main body 1. A chute 6 is formed in the support plate 2, and an armrest structure is slidably arranged in the chute 6. An insertion hole 8 is formed in the armrest structure, and a sliding insertion structure is arranged in the support plate 2, and the sliding insertion structure is inserted into the insertion hole 8. The armrest structure can be conveniently fixed by means of sliding insertion. A communication groove 9 is formed on the upper surface of the support plate 2, and an operating rod 10 capable of driving the sliding insertion structure to slide is arranged in the communication groove 9, which is convenient for the user to operate while sitting on the chair main body 1.
[0021] As Figure 3 shown, the armrest structure includes an armrest plate 3 and a sliding column 7. The armrest plate 3 is arranged above the support plate 2, and the sliding column 7 is fixedly connected to the lower part of the armrest plate 3, and the sliding column 7 is slidably arranged in the chute 6. The insertion hole 8 is formed in the sliding column 7. There are three insertion holes 8, and the three insertion holes 8 are equidistantly distributed up and down on the sliding column 7, which can realize the adjustment of three height positions of the armrest plate 3.
[0022] As Figure 4 shown, the sliding insertion structure includes an insertion rod 11 and a sliding plate 12. A spring groove 16 is formed in the support plate 2, and the sliding plate 12 is slidably arranged in the spring groove 16. The insertion rod 11 is fixedly connected to the sliding plate 12, and the insertion rod 11 is inserted into the insertion hole 8. The spring groove 16 is communicated with the communication groove 9, and the operating rod 10 is inserted into the spring groove 16 and fixedly connected to the sliding plate 12. The sliding plate 12 can be directly driven to slide by the operating rod 10 outside the support plate 2, so as to facilitate the control of the insertion and connection of the insertion rod 11 and the insertion hole 8. A guide rod 13 is fixedly connected to one side of the sliding plate 12. A guide groove 14 communicated with the spring groove 16 is formed in the support plate 2, and the guide rod 13 is inserted into the guide groove 14. The guide groove 14 and the guide rod 13 can play a guiding role in the sliding of the sliding plate 12. A compression spring 15 is sleeved on the guide rod 13, which can provide a restoring force for the sliding plate 12 to return to its original position. A compression amount is reserved when the compression spring 15 is installed, and a continuous pressure can be applied to the sliding plate 12, so as to increase the insertion stability of the insertion rod 11 and the insertion hole 8.
[0023] The principle of the present utility model
[0024] When sitting on the chair main body 1 to adjust the height of the armrest plate 3, only need to push the operating rod 10 to make the two operating rods 10 on the same support plate 2 move towards each other, as Figure 4As shown, the operating rod 10 drives the sliding plate 12 to slide, and the insertion rod 11 disengages from the insertion hole 8, that is, the fixation of the sliding column 7 is released. At the same time, the sliding plate 12 compresses the compression spring 15. Directly pull the armrest plate 3 to drive the sliding column 7 to slide up and down, select a suitable insertion hole 8 to align the insertion hole 8 with the insertion rod 11, release the operating rod 10, and under the action of the resilience of the compression spring 15, the sliding plate 12 slides back, driving the insertion rod 11 to re-insert into the insertion hole 8, thus quickly completing the fixation of the sliding column 7 and the armrest plate 3. During the whole process of adjusting the height of the armrest, no tools are designed to be used. Only the user needs to manually operate the operating rod 10 and the armrest plate 3. At the same time, the user does not need to leave the chair body 1, which greatly improves the convenience of adjusting the height of the office chair armrest.
