[0048] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0049] like Figure 1 The diagram shown is a structural schematic of the present invention, which provides an adjustable height base, including a support base 1, a fixed bracket 2 fixedly mounted on the support base 1, a movable bracket 3 movably mounted within the fixed bracket 2, and a height adjustment mechanism disposed between the fixed bracket 2 and the movable bracket 3.

[0050] The support base 1 is a long strip plate with a trapezoidal longitudinal section. Typically, the bases of this invention are used in pairs, respectively arranged on both sides of the supported component 6 (such as a television set) along its length. The two parallel support bases 1 stably support the supported component (such as a television set). Figure 13 and Figure 14 (As shown).

[0051] The fixing bracket 2 is fixedly installed in the middle of the support base 1 and extends vertically. The fixing bracket 2 has an open top and a hollow interior. The bottom of the fixing bracket 2 is fixed to the support base 1 by multiple screws. Preferably, the fixing bracket 2 has a square tube structure.

[0052] To facilitate the installation of the fixed bracket 2, an installation groove 1-1 is provided in the middle of the support base 1 for the fixed bracket 2 to be inserted and fixed.

[0053] The movable support 3 is adjustablely positioned within the fixed support 2, and its upper part is fixedly connected to the supported component 6. To adapt to the fixed support 2, the movable support 3 is a square column that matches the fixed support 2.

[0054] like Figure 2 As shown, in order to facilitate connection with the supported member 6, a connecting part 3-1 is provided on the upper part of the movable bracket 3, and a connecting hole 3-2a for the connecting member to pass through is provided on the connecting part 3-2. At the same time, an installation clearance groove 3-2b is provided at one end of the connecting part 3-2 located at the connecting hole 3-2a. The connecting member can be a screw.

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

[0056] In this example, two height adjusters 5 are provided on the outer periphery of the movable support 3. The two height fixers 5 can stably support the movable support 3 and meet the coordination requirements of height adjustment. It should be understood that more than two height adjusters 5 can be provided as needed, and this utility model does not impose any restrictions.

[0057] The movable support 3 is provided with a height adjustment groove 3-1 that cooperates with the height fixing device 5. The height adjustment groove 3-1 is recessed on the surface of the fixed support 3 and includes a first groove 3-1a for limiting the movable support 3 to a first position, a second groove 3-1b for limiting the movable support 3 to a second position, and a third groove connecting the first groove 3-1a and the second groove 3-1b. The height of the second position is greater than the height of the first position. That is, the first position is the state in which the movable support 3 is in a low position, and the second position is the state in which the movable support 3 is in a high position. When the movable support 3 is in the first position, the upper end of the height fixing device 5 is located in the first groove 3-1a (e.g., when the movable support 3 is in the first position, the upper end of the height fixing device 5 is located in the first groove 3-1a). Figure 2 , Figure 5 As shown), when the movable bracket 3 is in the second position, the upper end of the height fixing device 5 is located in the second groove 3-1b (as shown). Figure 4 , Figure 9 , Figure 11 (As shown).

[0058] like Figure 1 As shown, the height fixing device 5 includes a pull rod part 5-1, a first limiting part 5-2 disposed at the upper end of the pull rod part 5-1, and a second limiting part 5-3 disposed at the lower end of the pull rod part 5-1. The first limiting part 5-2 and the second limiting part 5-3 are both connected to the pull rod part 5-1 at a 90-degree angle. Preferably, the height fixing device 5 is made of stainless steel round tube by die casting.

[0059] like Figure 6 , Figure 10 , Figure 12 As shown, the third groove includes a first sliding groove 3-1c and a second sliding groove 3-1d extending vertically. The two ends of the first groove 3-1a are connected to the upper ends of the first sliding groove 3-1c and the second sliding groove 3-1d respectively, and a first limiting groove matching the height fixing device 5 is formed in the middle. A first step 3-1e is provided on one side of the first limiting groove to restrict the movement of the height fixing device 5 towards the first sliding groove 3-1c. A second step 3-1f is provided between the first groove 3-1a and the first sliding groove 3-1c to restrict the retraction of the height fixing device 5. A third step 3-1g is provided between the first groove 3-1a and the second sliding groove 3-1d to restrict the retraction of the height fixing device 5. The two ends of the second groove 3-1b are connected to the lower ends of the first sliding groove 3-1c and the second sliding groove 3-1d respectively, and a second limiting groove matching the height fixing device 5 is formed in the middle. A fourth step 3-1h is provided on one side of the second limiting groove to restrict the movement of the height fixing device 5 towards the second sliding groove 3-1d.

[0060] In this example, both the first groove 3-1a and the second groove 3-1b are V-shaped. The first step 3-1e is inclined towards the first slide 3-1c to limit and guide the movement of the upper end of the height fixer 5. The fourth step 3-1h is inclined towards the second slide 3-1d to limit and guide the movement of the lower end of the height fixer 5. The second step 3-1f creates a height difference between the first slide 3-1c and the first groove 3-1a, preventing the height fixer 5 from retracting into the first groove 3-1a when it moves into the first slide 3-1c (e.g., ...). Figure 7 and Figure 8 As shown, the third step 3-1f creates a height difference between the first groove 3-1a and the second slide groove 3-1d. When the height fixer 5 moves to the first groove 3-1a, it prevents it from retracting into the second slide groove 3-1d. Simultaneously, the second and third steps 3-1f also serve as audible cues. When the height fixer 5 moves from the second step 3-1f to the first slide groove 3-1c, or from the third step 3-1f to the first groove 3-1a, a clicking sound is emitted as a notification. The first limiting part 5-2 of the height fixer 5 slides within the first groove 3-1a, the third groove, and the second groove 3-1b to fix the height, while the second limiting part 5-3 is fixed to the fixed bracket 2.

[0061] like Figure 3 As shown, in order to facilitate the connection between the height fixing device 5 and the fixed bracket 2, the bottom of the fixed bracket 2 is provided with 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. Most of the height fixing device 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] To improve structural stability, such as Figure 3 As shown, a limiting block 1-2 is provided in the mounting groove 1-1 of the support base 1 to abut against the pull rod part 5-1. By abutting against the pull rod part 5-1 with the limiting block 1-2, the lower part of the height fixing device 5 can be positioned on the fixed bracket 2 to prevent it from detaching from the fixed bracket 2.

[0063] To facilitate the installation of the gas spring 4, a receiving cavity 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 receiving cavity. In this example, the pressure value of the gas spring 4 can be selected according to the weight of the supported component 6. This gas spring 4 is different from the conventional structure, including a cylinder, a piston set in the cylinder, and a piston rod connected to the piston. The cylinder is filled with high-pressure nitrogen. There are no connecting parts on the cylinder and the piston rod. The movable bracket 3 is supported by the piston rod abutting against it.

[0064] The working principle of this utility model is as follows:

[0065] When the movable bracket 3 is in the first position, there is a gap between the bottom of the movable bracket 3 and the fixed bracket 2 (e.g., Figure 5 As shown), the gas spring 4 is in a partially extended state. When the movable bracket 3 is pressed, the first limiting part 5-1 at the upper end of the height fixing device 5 passes through the second step 3-1f and disengages from the first groove 3-1a (as shown). Figure 8 As shown), when a clicking sound is heard, release your hand. The gas spring 4 loses its restraint, and the movable bracket 3 rises under the action of the gas spring 4. After that, the first limiting part 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 part 3-1b. At this time, the movable bracket 3 is in the second position (as shown). Figure 9 (As shown); Press the movable bracket 3, the first limiting part 5-1 disengages from the second groove 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 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, allowing for height switching simply by pressing it manually.

[0067] The above examples are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
