[0055] The height adjustment mechanism is used to adjust the position of the movable bracket 3 in the fixed bracket 2, and includes a gas spring 4 arranged between the fixed bracket 2 and the movable bracket 3 and a plurality of height fixers 5 arranged on the outer periphery of the movable bracket 3. The lower end of the height fixer 5 is limited on the fixed bracket 2 and the upper end is adjustably arranged on the movable bracket 3.

[0056] In this example, two height adjusters 5 are relatively arranged on the outer periphery of the movable bracket 3. The two height fixers 5 can stably support the movable bracket 3 while meeting the coordination requirements of the height adjustment. It should be understood that more than two height adjusters 5 can be set as needed, and the present invention does not limit this.

[0057] A height adjustment groove 3-1 cooperating with the height fixer 5 is provided on the movable bracket 3, and the height adjustment groove 3-1 is recessed on the surface of the fixed bracket 3, including a first groove portion 3-1a for limiting the movable bracket 3 to be located at a first position, a second groove portion 3-1b for limiting the movable bracket 3 to be located at a second position, and a third groove portion connecting the first groove portion 3-1a and the second groove portion 3-1b, wherein the height of the second position is greater than the height of the first position, that is, the first position is a state where the movable bracket 3 is in a low position, and the second position is a state where the movable bracket 3 is in a high position. When the movable bracket 3 is in the first position, the upper end of the height fixer 5 is located in the first groove portion 3-1a (such as Figure 2 , Figure 5 When the movable bracket 3 is located at the second position, the upper end of the height fixer 5 is located at the second groove portion 3-1b (as shown in FIG. Figure 4 , Fig. 9 , Fig.11 shown).

[0058] like Figure 1 As shown, the height fixer 5 includes a pull rod portion 5-1, a first limit portion 5-2 arranged at the upper end of the pull rod portion 5-1, and a second limit portion 5-3 arranged at the lower end of the pull rod portion 5-1. The first limit portion 5-2 and the second limit portion 5-3 are both connected to the pull rod portion 5-1 at a ninety-degree angle. Preferably, the height fixer 5 is made of a stainless steel round tube die-casting.

[0059] like Figure 6 , Fig.10 , Fig.12 As shown, the third groove portion includes a first slide groove 3-1c and a second slide groove 3-1d extending in the vertical direction, the two ends of the first groove portion 3-1a are respectively connected with the upper ends of the first slide groove 3-1c and the second slide groove 3-1d, and a first limiting groove matching the height fixer 5 is formed in the middle, and a first step 3-1e for limiting the movement of the height fixer 5 to the first slide groove 3-1c is provided on one side of the first limiting groove, a second step 3-1f for limiting the retreat of the height fixer 5 is provided between the first groove portion 3-1a and the first slide groove 3-1c, and a third step 3-1g for limiting the retreat of the height fixer 5 is provided between the first groove portion 3-1a and the second slide groove 3-1d; the two ends of the second groove portion 3-1b are respectively connected with the lower ends of the first slide groove 3-1c and the second slide groove 3-1d, and a second limiting groove matching the height fixer 5 is formed in the middle, and a fourth step 3-1h for limiting the movement of the height fixer 5 to the second slide groove 3-1d is provided on one side of the second limiting groove.

[0060] In this example, the first groove portion 3-1a and the second groove portion 3-1b are both V-shaped, the first step 3-1e is inclined toward the first slide groove 3-1c to limit and guide the movement of the upper end of the height fixer 5, and the fourth step 3-1h is inclined toward the second slide groove 3-1d to limit and guide the movement of the lower end of the height fixer 5. The second step 3-1f makes the position where the first slide groove 3-1c and the first groove portion 3-1a are connected have a height difference, when the height fixer 5 moves into the first slide groove 3-1c, it can avoid retreating into the first groove portion 3-1a (such as Figure 7 and Figure 8 As shown in the figure, the third step 3-1f makes the connection position between the first slot 3-1a and the second slot 3-1d have a height difference. When the height fixer 5 moves to the first slot 3-1a, it can avoid retreating to the second slot 3-1d. At the same time, the second step 3-1f and the third step 3-1f can also play a role of sound prompt. When the height fixer 5 moves to the first slot 3-1c via the second step 3-1f, or moves to the first slot 3-1a from the third step 3-1f, a click sound will be emitted to serve as a prompt. The first limit part 5-2 of the height fixer 5 slides in the first slot 3-1a, the third slot and the second slot 3-1b to achieve height fixation, and the second limit part 5-3 is limited on the fixed bracket 2.

[0061] like Figure 3 As shown, in order to facilitate the connection between the height fixer 5 and the fixed bracket 2, a through groove 2-1 for the second limiting part 5-3 to extend out and a limiting hole 2-2 for the second limiting part 5-3 to be inserted are provided at the bottom of the fixed bracket 2. Most of the height fixer 5 is located inside the fixed bracket 2, and its lower part is positioned in the limiting hole 2-2 after extending out through the through groove 2-1.

[0062] In order to improve the stability of the structure, Figure 3 As shown, a limit block 1-2 abutting against the pull rod portion 5-1 is provided in the installation groove 1-1 of the support seat 1. The limit block 1-2 abuts against the pull rod portion 5-1 to position the lower portion of the height fixer 5 on the fixed bracket 2 to prevent it from detaching from the fixed bracket 2.

[0063] In order to facilitate the installation of the gas spring 4, a accommodating chamber for the gas spring 4 is provided at the bottom of the movable bracket 3. The cylinder of the gas spring 4 abuts against the fixed bracket 2 and the piston rod abuts against the top of the accommodating chamber. The gas spring 4 in this example can select a pressure value according to the weight of the supported member 6. The gas spring 4 is different from the conventional structure and includes a cylinder, a piston arranged in the cylinder and a piston rod connected to the piston. The cylinder is filled with high-pressure nitrogen. No connecting parts are provided on the cylinder and the piston rod. The movable bracket 3 is supported by abutting against the piston rod.

[0064] The working principle of the present invention is:

[0065] When the movable bracket 3 is located at the first position, there is a distance between the bottom of the movable bracket 3 and the fixed bracket 2 (such as Figure 5 As shown), the gas spring 4 is in a partially extended state, pressing the movable bracket 3, the first limit portion 5-1 at the upper end of the height fixer 5 passes the second step 3-1f and disengages from the first groove portion 3-1a (as shown Figure 8 As shown in the figure, when the hand is released after a click sound, the gas spring 4 loses its restriction, and the movable bracket 3 is lifted under the action of the gas spring 4. Thereafter, the first limiting portion 5-1 slides along the first slide groove 3-1c until it passes the fourth step 3-1h and reaches the second limiting groove position of the second groove portion 3-1b. At this time, the movable bracket 3 is in the second position (as shown in the figure). Fig. 9 As shown); press the movable bracket 3, the first limiting portion 5-1 disengages from the second groove portion 3-1b and slides upward along the second slide groove 3-1d until it passes the third step 3-1g and returns to the first groove portion 3-1a. When a click sound is heard, release your hand, the gas spring 4 rebounds and drives the movable bracket 3 back to the first position.

[0066] In summary, the base has a simple structure and is easy to operate, and the height can be switched by manual pressing.
