[0023] Example 1 like Figure 1 As shown, a chair height-adjustable armrest structure includes an armrest base 1, a telescopic arm 2 slidably mounted on the armrest base 1, and an armrest body 3 mounted on the free end of the telescopic arm 2; combined with Figure 2 As shown, it also includes an adjustment mechanism 4 for controlling the telescopic arm 2 to perform multi-level sliding adjustment. The adjustment mechanism 4 includes a press member 41 for pressing to control sliding unlocking. The press member 41 is provided to cover at least part of the outer wall of the telescopic arm 2 so that the user can trigger the press by holding it.

[0024] As an improvement, the pressing member 41 is arranged to cover at least one side of the outer wall of the telescopic arm 2.

[0025] In this embodiment, the pressing element 41 is configured to cover the outer wall of the telescopic arm 2 over a large area, which effectively increases the pressing trigger area, making it convenient for users to quickly trigger the pressing by holding the arm. This makes the operation convenient, especially suitable for blind pressing, and greatly improves the ease of operation and user experience.

[0026] As an improvement, such as Figure 3-4 As shown, one end of the pressing member 41 is rotatably mounted on the telescopic arm 2, and the other end is provided with a pressing part 411 extending into the telescopic arm 2. The adjustment mechanism 4 also includes a gear adjustment component 42 located in the telescopic arm 2. When the pressing member 41 is gripped and force is applied by the user, it rotates slightly, and the pressing part 411 touches the gear adjustment component 42 to rotate and unlock.

[0027] As an improvement, such as Figure 3As shown, the gear adjustment assembly 42 includes an adjustment arm 421 rotatably mounted on the telescopic arm 2, combined with... Figure 7 As shown, the armrest seat 1 has a plurality of gear slots 20 arranged along the sliding direction of the telescopic arm 2. The free end of the adjusting arm 421 has a buckle 420 that matches and is locked in the gear slot 20. The pressing part 411 is in contact with the adjusting arm 421 and drives the adjusting arm 421 to rotate so that the buckle 420 disengages from the gear slot 20.

[0028] When the pressing part 411 is pressed, the pressing part 41 rotates slightly inward, so that the pressing part 411 touches the telescopic arm 2, causing the telescopic arm 2 to rotate and the buckle 420 to disengage from the position groove 20. At this time, it is unlocked, and the telescopic arm 2 can freely extend and slide to adjust the overall height.

[0029] As an improvement, the top of the adjusting arm 421 is rotatably mounted on the telescopic arm 2, and the bottom of the adjusting arm 421 is provided with the buckle 420.

[0031] In this embodiment, the bottom of the pressing member 41 is rotatably mounted on the telescopic arm 2, and the top is limited within the telescopic arm 2 by the stop part 413 and has a certain amount of room for movement. Thus, the user can achieve a slight rotation of the pressing member 41 by holding and pressing it lightly, and open and unlock the adjusting arm 421 through the lever action. The operation is effortless and the user experience is good.

[0032] As an improvement, the pressing part 411 abuts against the middle section of the adjusting arm 421.

[0033] As an improvement, such as Figure 3 As shown, the gear adjustment assembly 42 also includes an elastic element 422 that drives the adjustment arm 421 to reverse and reset. An arm 423 extends laterally from the top of the adjustment arm 421, and the elastic element 422 is connected between the arm 423 and the top surface of the telescopic arm 2.

[0034] For illustration, the support arm 423 extends laterally from the top end of the adjusting arm 421, and the buckle 420 extends laterally from the bottom end of the adjusting arm 421, with its extension direction opposite to that of the support arm 423.

[0035] When the user releases their grip, the adjusting arm 421 reverses and resets under the elastic restoring force of the elastic element 422, that is, the buckle 420 is re-locked into a certain gear slot 20. Since the pressing part 411 is in contact with the adjusting arm 421, it drives the pressing part 41 to synchronously reverse and reset. At this time, under the action of the stop part 413, the pressing part 41 will not come out of the telescopic arm 2 when it rotates outward to reset, so the structure is stable and reliable.

[0036] In addition, the top of the adjusting arm 421 is provided with a mounting groove for limiting the elastic element 422, and the upper part of the support arm 423 is also provided with a pin for sleeved on the elastic element 422, thereby limiting the elastic element 422.

[0037] As an improvement, the telescopic arm 2 is hollow and slidably sleeved on the outside of the armrest seat 1, and the armrest seat 1 is hollow and contains the gear adjustment component 42.

[0038] Example 2 The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that: like Figure 1 As shown, as an improvement, the pressing member 41 is arranged in a "C" shape to cover and extend the length of the telescopic arm 2.

[0039] In this embodiment, the pressing member 41 is arranged in a "C" shape to cover the telescopic arm 2, which is highly compatible with the user's hand grip posture, making it easy to operate and providing a good user experience.

[0040] Furthermore, it is worth noting that in this embodiment, the large-area pressing element 41 also has the effect of a hidden button, making the overall shape of the armrest structure more simple and aesthetically pleasing, which meets the modern and minimalist aesthetic needs of consumers.

[0041] As an improvement, such as Figure 5-6 As shown, pin holes 21 are provided on both opposite side walls of the telescopic arm 2, and a matching pin shaft 412 is provided on the pressing member 41, which is combined with... Figure 4 As shown, the pin 412 is rotatably limited within the pin hole 21.

[0042] As a preferred option, combined with Figure 3 , 5 The telescopic arm 2 has a through hole 22 for the pressing member 41 to pass through.
