[0020] Example one
[0021] As Figures 1 to 3 shown, the embodiment provides a tree trunk winter cold protection device for landscaping, which comprises an outer fixed ring 1, long screw rods 2 are slidably penetrated and arranged on the two sides of the outer fixed ring 1, first anti-loose nuts 6 are threadedly sleeved on the two ends of the long screw rods 2, a second square plate 9 is fixedly arranged at the top end of the outer fixed ring 1, a first square plate 7 is fixedly arranged at the bottom end of the outer fixed ring 1, a short screw rod 8 is fixedly arranged at the bottom end of the first square plate 7, a second anti-loose nut 10 is threadedly sleeved on the bottom end outer surface of the short screw rod 8 through the second square plate 9, an inner fixed ring 3 is arranged in the outer fixed ring 1, a plug-in block 11 is fixedly arranged at the bottom end of the inner fixed ring 3, the outer fixed ring 1, the inner fixed ring 3 and the thermal blanket layer 4 are all arranged in an arc shape, the outer fixed ring 1, the inner fixed ring 3 and the thermal blanket layer 4 are provided with the same number of groups, every two groups of the outer fixed ring 1, every two groups of the inner fixed ring 3 and every two groups of the thermal blanket layer 4 are symmetrically distributed, the long screw rods 2 are provided in multiple groups, the two ends of every four groups of the long screw rods 2 are respectively slidably penetrated through the two ends of every two groups of the symmetric outer fixed ring 1, an arc-shaped groove is arranged at the top end of the inner fixed ring 3 and is matched with the plug-in block 11, the plug-in block 11 is slidably arranged in the arc-shaped groove, and the two are closely attached without gap.
[0022] In this embodiment, when installing the device, first, the two symmetrical groups of heat preservation cloth layers 4 are tightly attached to the surface of the tree trunk, then the two ends of the long screw rod 2 are inserted through one side of the two symmetrical groups of outer fixing rings 1, and then the first anti-loose nut 6 is rotated to tightly attach one side of the first anti-loose nut 6 to one side of the outer wall of the outer fixing ring 1, thereby limiting and fixing the two symmetrical groups of outer fixing rings 1. It should be noted that after the two symmetrical groups of outer fixing rings 1 are installed, the spring 12 should be in a non-stretched state, and the heat preservation cloth layer 4 should be tightly attached to the tree trunk. Under the obstruction of the first anti-loose nut 6, the two symmetrical groups of outer fixing rings 1 will not easily separate. When the tree trunk is high, the other two symmetrical groups of outer fixing rings 1 can be placed above the two symmetrical groups of outer fixing rings 1, so that the short screw rod 8 slides through the second square plate 9, one side of the first square plate 7 is attached to one side of the second square plate 9, and the two symmetrical groups of insertion blocks 11 are slid into the arc-shaped slots at the top of the two symmetrical groups of inner fixing rings 3. Then the second anti-loose nut 10 is rotated until one side of the second anti-loose nut 10 is tightly attached to the other side of the second square plate 9. Under the obstruction of the second anti-loose nut 10, the first square plate 7 and the second square plate 9 will not easily separate, thereby realizing the splicing and fixing of the four groups of outer fixing rings 1 and the four groups of inner fixing rings 3. According to the above method, a plurality of groups of outer fixing rings 1 and a plurality of groups of inner fixing rings 3 are stacked in turn until the height of the plurality of groups of outer fixing rings 1 and the plurality of groups of inner fixing rings 3 is approximately the same as the height of the part of the tree trunk that needs to be protected from cold.
[0023] Embodiment Two
[0024] As Figure 1 With Figure 4 the same concept as the above embodiment, the inner wall of the inner fixing ring 3 is fixed with a heat preservation cloth layer 4, the outer wall of the inner fixing ring 3 is fixed with a limiting column 5, and the outer surface of the limiting column 5 is slidably sleeved with a spring 12. The two ends of the spring 12 are respectively fixedly connected to the inner wall of the outer fixing ring 1 and the outer wall of the inner fixing ring 3. The heat preservation cloth layer 4 is a heat preservation layer made of elastic polyurethane foam material. Such heat preservation layer has certain elasticity and good heat preservation effect. The surface of the outer fixing ring 1 is provided with a circular hole, and one end of the limiting column 5 is slidably inserted through the inside of the circular hole, leaving a gap therebetween.
[0025] In this embodiment, when the tree trunk grows, its diameter will gradually increase, thereby first extruding the heat preservation cloth layer 4, so that the two groups of heat preservation cloth layers 4 drive the two groups of inner fixing rings 3 to expand in the opposite direction. The inner fixing ring 3 drives the limiting column 5 to move synchronously, so that the limiting column 5 slides along the circular hole on the surface of the outer fixing ring 1. The inner fixing ring 3 simultaneously extrudes the spring 12, so that the spring 12 is compressed. Under the rebounding force of the spring 12, the inner fixing ring 3 and the heat preservation cloth layer 4 have a reverse extrusion force on the tree trunk, thereby ensuring that the heat preservation cloth layer 4 can be tightly attached to the surface of the tree trunk, and the growth of the tree trunk is not excessively limited.
