[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides a height-adjustable lattice column, including a base plate 1. The upper surface of the base plate 1 has multiple ring-shaped fixing mechanisms 3. An adjusting mechanism 2 is fixedly mounted on the upper surface of the base plate 1. A lattice column frame 4 is fixedly mounted on the upper surface of the adjusting mechanism 2. The adjusting mechanism 2 includes multiple lifting cylinders 28. The lower end of each lifting cylinder 28 is fixedly connected to the upper surface of the base plate 1. A lifting rod 26 is slidably mounted on the inner side of each lifting cylinder 28. The upper end of the lifting rod 26 is fixedly connected to the lower end of the lattice column frame 4. An adjusting frame 20 is fixedly mounted on the upper surface of the base plate 1. An adjusting plate 22 is fixedly mounted on the upper end of the adjusting frame 20. An adjusting screw 24 is fixedly mounted on the lower end of the lattice column frame 4. The adjusting screw 24 slides with the adjusting plate 22. Two adjusting nuts 23 are threaded onto the outer side of the adjusting screw 24. The adjusting mechanism 2 is used to adjust the lattice column frame 4 when necessary. When adjusting the height, first loosen the adjusting nut 23 so that it no longer exerts clamping force on the adjusting screw 24. Then, the adjusting screw 24 can be slid up and down. Since the adjusting screw 24 is in sliding fit with the adjusting plate 22, and the upper end of the adjusting screw 24 is fixedly connected to the mounting bracket 25, which is connected to the lower end of the lattice column frame 4, the up and down sliding of the adjusting screw 24 will drive the lattice column frame 4 and its entire upper structure to rise and fall together. At the same time, the lifting rod 26 will slide in the lifting groove 27 of the lifting cylinder 28 to ensure the smoothness and verticality of the lifting process. After adjusting to the required height, tighten the adjusting nut 23 so that it exerts sufficient clamping force on the adjusting screw 24, thereby fixing the height of the lattice column frame 4. The anti-slip rubber ring 21 increases the friction between the adjusting nut 23 and the adjusting screw 24, preventing them from loosening under the action of external forces such as vibration.

[0018] The upper end of the lifting cylinder 28 is provided with a lifting groove 27, which slides and fits with the lifting rod 26. Two anti-slip rubber rings 21 are slidably sleeved on the outer side of the adjusting screw 24. The lower end of the lattice column frame 4 is fixedly provided with a mounting bracket 25, and the lower surface of the mounting bracket 25 is fixedly connected to the upper end of the adjusting screw 24. The lifting rod 26 can slide in the lifting groove 27. The anti-slip rubber rings 21 can prevent the adjusting screw 24 from becoming loose. The mounting bracket 25 can fix the adjusting screw 24.

[0019] The fixing mechanism 3 includes a fixing cylinder 30, which is located on the upper surface of the base plate 1. The lower end of the fixing cylinder 30 has multiple annularly distributed expansion grooves 31. A fixing screw 35 is slidably mounted on the inner side of the fixing cylinder 30, and a fixing nut 37 is threaded onto the outer side of the fixing screw 35. An expansion rod 34 is fixed to the lower end of the fixing screw 35, and an expansion block 33 is fixed to the lower end of the expansion rod 34. The expansion block 33 slides within the lower inner side of the fixing cylinder 30. When it is necessary to fix the height-adjustable lattice column to the ground, the fixing cylinder 30 is first placed in the pre-drilled hole on the upper surface of the base plate 1, and then the fixing screw 35 is pushed by rotating the fixing nut 37. The expansion rod 34 and expansion block 33 at its lower end move outward. Since the fixed cylinder 30 is a plastic cylinder and its lower end has multiple annularly distributed expansion grooves 31, when the expansion block 33 moves outward, it will squeeze the lower end of the fixed cylinder 30, causing it to undergo plastic deformation and expand, thus tightly fitting into the reserved hole. At the same time, the anti-slip texture 32 increases the friction between the fixed cylinder 30 and the ground, preventing the lattice column from sliding. The anti-loosening washer 36 is used to prevent the fixing nut 37 from loosening due to vibration during long-term use. Through this fixing mechanism 3, the stable installation of the height-adjustable lattice column in different terrains and environments can be ensured.

[0020] The lower end of the fixing cylinder 30 is fixed with multiple anti-slip patterns 32 arranged in a linear pattern. The outer side of the fixing screw 35 is slidably fitted with an anti-loosening washer 36. The fixing cylinder 30 is a plastic cylinder. The anti-slip patterns 32 can increase the friction coefficient with the reserved hole. The anti-loosening washer 36 can prevent the fixing mechanism 3 from loosening. The plastic cylinder 30 can effectively expand and fix within the reserved hole.

[0021] Working principle: When the height of the lattice column frame 4 needs to be adjusted using the adjustment mechanism 2, first loosen the adjusting nut 23 so that it no longer exerts clamping force on the adjusting screw 24. Then, the adjusting screw 24 can be slid up and down. Since the adjusting screw 24 is slidably engaged with the adjusting plate 22 and the upper end of the adjusting screw 24 is fixedly connected to the mounting bracket 25, and the mounting bracket 25 is connected to the lower end of the lattice column frame 4, the up and down sliding of the adjusting screw 24 will drive the lattice column frame 4 and its entire upper structure to rise and fall together. At the same time, the lifting rod 26 will slide in the lifting groove 27 of the lifting cylinder 28 to ensure the smoothness and verticality of the lifting process. After adjusting to the required height, tighten the adjusting nut 23 so that it exerts sufficient clamping force on the adjusting screw 24, thereby fixing the height of the lattice column frame 4. The anti-slip rubber ring 21 increases the friction between the adjusting nut 23 and the adjusting screw 24, preventing them from loosening under the action of external forces such as vibration.

[0022] When it is necessary to fix the height-adjustable lattice column to the ground, first place the fixing cylinder 30 in the reserved hole on the upper surface of the base plate 1, and then push the fixing screw 35 and its lower expansion rod 34 and expansion block 33 to move outward by rotating the fixing nut 37. Since the fixing cylinder 30 is a plastic cylinder and its lower end has multiple annularly distributed expansion grooves 31, when the expansion block 33 moves outward, it will squeeze the lower end of the fixing cylinder 30, causing it to undergo plastic deformation and expand, thus tightly fitting into the reserved hole. At the same time, the anti-slip texture 32 increases the friction between the fixing cylinder 30 and the ground, preventing the lattice column from sliding. The anti-loosening washer 36 is used to prevent the fixing nut 37 from loosening due to vibration during long-term use. Through this fixing mechanism 3, the stable installation of the height-adjustable lattice column in different terrains and environments can be ensured.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
