[0044] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0045] See Figures 1 to 4 The diagram below is a structural schematic of an embodiment of the present invention. It provides a height-adjustable base, including a mounting frame 2, a support base 1 mounted on the mounting frame 2, and a locking component 3.

[0046] like Figure 11 As shown, the mounting bracket 2, which is fixedly connected to the television body 5, includes a vertically arranged base plate 2-1 and a cover plate 2-2 covering the base plate 2-1. There is a slot between the cover plate 2-2 and the base plate 2-1 for the support base 1 to be inserted.

[0047] Support 1, which has a first position and a second position with different heights relative to mounting bracket 2 (e.g. Figure 5 and Figure 6As shown in the figure, the second position is located above the first position. The support base 1 includes a support part, a first locking part 1-3 and a second locking part 1-4. The first locking part 1-3 is disposed at the upper end of the support part, and the second locking part 1-4 is disposed in the middle of the first locking part 1-3 and forms a locking groove 1-5 between the second locking part 1-3 and the first locking part 1-3.

[0048] Specifically, the support includes a first support rod 1-1 and a second support rod 1-2 connected in a T-shape. The first support rod 1-1 is arranged horizontally to fit against the mounting surface, and the second support rod 1-2 is arranged vertically. The first locking part 1-3 is L-shaped, and the second locking part 1-4 is connected to the middle of the first locking part 1-3 to form a locking groove 1-5 in the middle of the first locking part 1-3.

[0049] Locking assembly 3 includes a locking lever 3-1 and an elastic element 3-2 disposed between the locking lever 3-1 and the base plate 2-1. Preferably, the elastic element 3-2 is a spring. The locking lever 3-1 has a first state of being close to the support base 1 and a second state of being away from the support base 1 in the horizontal direction relative to the mounting bracket 2 (e.g., ...). Figures 7 to 9 As shown, when the locking lever 3-1 is in the first state, the spring is in a free state, the support seat 1 is in the first position, and the locking lever 3-1 abuts against the upper end of the first locking part 1-3. When the locking lever 3-1 is in the second state, the spring is compressed, the support seat 1 is in the second position, and the locking lever 3-1 engages with the second locking part 1-4. Thus, the locking of the support seat 1 at different height positions can be achieved through the cooperation of the locking assembly 3 and the support seat 1.

[0050] To facilitate the positioning of the height of the support base 1, a positioning component is also included. Specifically, the positioning component includes two elastic positioning elements 4 arranged on the support base 1 and spaced apart along the height direction. At the same time, the mounting bracket 2 is provided with three positioning holes that match the two elastic positioning elements 4. When the support base 1 is in the first position, the two elastic positioning elements 4 are located in the two lower positioning holes. When the support base 1 is in the second position, the two elastic positioning elements 4 are located in the two upper positioning holes. Preferably, the elastic positioning elements 4 are spring plungers.

[0051] like Figure 10As shown, the locking lever 3-1 includes a first lever 3-1a near the support base 1 and a second lever 3-1b away from the support base 1. A first guide portion 2-3 that slides with the first lever 3-1a and a second guide portion 2-4 that slides with the second lever 3-1b are provided on the base plate 2-1. An elastic member 3-2 is sleeved on the second lever 3-1b and located between the first lever 3-1a and the second guide portion 3-1b. Specifically, the first lever 3-1a is approximately rectangular, the second lever 3-1b is cylindrical, the first guide portion 2-3 has a groove matching the first lever 3-1a, and the second guide portion 2-4 has a through hole for the second lever 3-1b to pass through. A limiting portion 3-1d is provided at the end of the second lever 3-1b to confine the second lever 3-1b within the second guide portion 2-4.

[0052] When the support base 1 is in the second state, in order to facilitate the locking between the locking rod 3-1 and the support base 1, a locking block 3-1c is provided on the side of the first rod 3-1a facing the base plate 2-1 (e.g., Figure 9 As shown, the locking block 3-1c can extend from above into the locking groove 1-5 between the first locking part 1-3 and the second locking part 1-4, thereby achieving the locking between the locking rod 3-1 and the support base 1.

[0053] To facilitate the operation of the locking assembly 3, the locking assembly 3 also includes an operating part 3-3 that is fixedly connected to the first rod 3-1a. The operating part 3-3 is fixed to one end of the first rod 3-1a via a connecting block 3-4, and the second rod 3-1b passes through the connecting block 3-4.

[0054] To improve the stability of locking component 3, such as Figure 12 As shown, a first limiting seat 6 and a second limiting seat 7 are arranged at intervals on the base plate 2-1, and an elastic limiting member 3-5 is provided on the connecting block 3-4. When the locking rod 3-1 is in the first state, the elastic limiting member 3-5 extends into the first limiting hole on the first limiting seat 6; when the locking rod 3-1 is in the second state, the elastic limiting member 3-5 extends into the second limiting hole on the second limiting seat 7. The elastic limiting member 3-5 is a protruding structure made of elastic material.

[0055] The working principle of this invention is as follows:

[0056] When the support base 1 is in the first position, the two elastic positioning elements 4 are located in the two positioning holes below the cover plate 2-2. At this time, the elastic element 3-2 is in a free state, and the locking rod 3-1 abuts against the upper end of the first locking part 1-3 to lock the support base 1. Pulling the operating part 3-3 of the locking assembly 3 causes the locking rod 3-1 to move away from the support base 1, and the elastic element 3-2 is compressed. At this time, the TV or monitor moves down under the action of gravity. When the two elastic positioning elements 4 are located in the two positioning holes above the cover plate 2-2, the locking block 3-1c on the first rod 3-1a engages with the locking groove 1-5, and the locking rod 3-1 and the support base 1 are locked together. When the TV or monitor is lifted, the support base 1 slides down along the mounting bracket 2, completing the height increase of the support base 1. The elastic element 3-2 resets, and the locking rod 3-1 abuts against the upper end of the first locking part 1-3 to lock.

[0057] In summary, this device allows for height adjustment of the television, has a simple structure, and is easy to operate.

[0058] The above examples are merely illustrative of the technical concept and features of the present invention, intended to enable those skilled in the art to understand the content of the invention and implement it accordingly, and should not be construed as limiting the scope of protection of the present invention. All equivalent transformations or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
