Detailed Implementation

[0056] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0057] Example 1 Refer to the accompanying drawings in the instruction manual, such as Figures 1-20 As shown, a telescopic support 2 includes a vertical rod 4, which is a hollow tube, and a first through hole 47 on the vertical rod 4. It also includes a second sleeve 5, which has a through groove 51 extending vertically through the vertical rod 4, allowing the vertical rod 4 to pass through and move up and down along the through groove 51. Multiple first limiting holes 52 are vertically provided on the side wall of the second sleeve 5. It also includes a mounting block 41, which is fixed inside the vertical rod 4. A telescopic pin 411 is installed inside the mounting block 41. A second through hole 48 is provided on the mounting block 41. When the pin 411 is retracted inside the mounting block 41, the vertical rod 4 can move up and down along the second sleeve 5. The pin 411 passes through the second through hole 48 and the first through hole 47 in sequence, extending out to the first limiting hole 52, thus fixing the vertical rod 4 to the second sleeve 5. It also includes several support rods 6, which provide fixed support for the second sleeve 5.

[0058] Specifically, it also includes a first sleeve 3, a lifting member 33, a slider 43, a sliding member 44, and a connecting body 42.

The first sleeve 3 is a hollow structure with an open bottom, and an installation groove 32 is provided on the top of the first sleeve 3. The lifting member 33 is disposed within the installation groove 32 and can move up and down along the installation groove 32. Two partitions 414 are provided inside the mounting block 41, forming a first mounting groove 412 between the two partitions 414. The slider 43 is disposed within the first mounting groove 414, and a second through hole 48 is located on one side of the first mounting groove 414. A pin 411 is fixed to the end of the slider 43 and can extend out of the second through hole 48. One side surface of the slider 43 is set as a first inclined surface. A slider 44 is disposed within the mounting block 41. The slider 44 includes a connecting block 441 and a guide rail 442 fixed below the connecting block 441. One side surface of the guide rail 442 is configured as a second inclined surface. One end of the connecting body 42 is connected to the lifting member 33, and the other end is connected to the connecting block 441. When the lifting member 33 moves up and down, the first inclined surface moves against the second inclined surface, causing the slider 43 to move horizontally within the first mounting groove 412, thereby allowing the pin 411 to be accommodated within or protrude from the second through hole 48.

[0059] Furthermore, a second limiting plate 443 is provided at the bottom end of the guide rail 442 of the slider 44, and the slider 44 moves upward until the second limiting plate 443 contacts the partition 414.

[0060] Furthermore, the mounting block 41 is provided with a first limiting plate 415 protruding outward. A first baffle 45 is fixedly provided on one side of the mounting block 41, and the bottom of the first baffle 45 contacts the first limiting plate 415. The first limiting plate 415 restricts the movement of the slider 43 and the sliding member 44 within the mounting block 41.

[0061] Furthermore, spherical protrusions 421 are provided at both ends of the connector 42. A first receiving groove 444 is provided on one side of the connector block 441, and a second receiving groove 31 is provided on one side of the lifting member 33. The spherical protrusions 421 at both ends of the connector 42 are respectively engaged in the first receiving groove 444 and the second receiving groove 31.

[0062] Furthermore, a scale plate 46 is attached and fixed to the surface of the vertical rod 4, and multiple scales are arranged vertically on the scale plate 46; a scale notch 53 for scale display is provided on the surface of the second sleeve 5.

[0063] Furthermore, there are two upper connecting bodies 34, symmetrically arranged on the first sleeve 3. The upper connecting body 34 is arc-shaped, with the arc opening facing upwards on the first sleeve 3. There are two support rods 6, symmetrically arranged at the bottom of the second sleeve 5, forming a triangle with the ground. The bottom of the second sleeve 5 has second mounting slots 54 on both sides for inserting and fixing the support rods 6, with one end of the second mounting slots 54 closed. A first connecting member 61 is provided between the two support rods 6. The first connecting member 61 includes a connecting sleeve 611 sleeved on the support rod 6 and a reinforcing rod 612 integrally connected to the connecting sleeves 611 on both sides. The connecting sleeve 611 is fixedly connected to the support rod 6, and the reinforcing rod 612 is an arc-shaped rod with the center of curvature facing the ground.

[0064] Furthermore, the top of the first sleeve 3 is provided with an installation groove 32, and a lifting element 33 is provided protruding from the upper surface of the installation groove 32.

[0065] The specific height adjustment process for telescopic bracket 2 is as follows: Figure 19 As shown, when the height of the telescopic bracket 2 is adjusted, the connecting body 42 is subjected to an upward force and moves upward. The connecting body 42 drives the sliding member 44 to move upward along the first mounting groove 412 through the first receiving groove 444. During the movement, the slider 43 slides downward relative to the guide rail 442 on the sliding member 44, so that the pin 411 gradually retracts inward through the second through hole 48 until the second limiting plate 443 contacts the partition plate 414. At this time, the pin 411 is completely retracted, and then the height of the telescopic bracket 2 is adjusted.

[0066] like Figure 20 As shown, after the height of the telescopic bracket 2 is adjusted, the sliding member 44 moves downward along the first mounting groove 412 under the influence of gravity. During the movement, the slider 43 slides upward relative to the guide rail 442 on the sliding member 44, and the pin 411 gradually extends outward through the first limiting block 52 until the bottom of the connecting block 441 contacts the partition 414. At this time, the pin 411 extends completely out of the second through hole 48, and then passes through the first through hole 47 on the vertical rod 4 and the first limiting hole 52 on the second sleeve 5, so that the height of the telescopic bracket 2 remains unchanged after adjustment.

[0067] In addition, to facilitate the movement of the telescopic bracket 2, a caster wheel 9 is provided at the bottom of the support rod 6, and the caster wheel 9 is detachably connected to the support rod 62.
