[0022] 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.

[0023] like Figure 1 As shown, a tree antifreeze device for garden maintenance includes: a base shell 1 surrounding the bottom of the tree, with two base shells 1; a hemp rope 2 disposed inside the base shell 1; a lifting shell 3 slidably connected to the base shell 1; an observation mechanism 4 disposed on the side wall of the lifting shell 3; and windproof stickers 5 disposed on the top and side wall of the lifting shell 3.

[0024] like Figure 2 As shown, the bottom shell 1 includes an inner shell 11 and an outer shell 12. Both the inner shell 11 and the outer shell 12 are semi-circular. The diameter of the outer shell 12 is larger than the diameter of the inner shell 11. The bottoms of the inner shell 11 and the outer shell 12 are fixed together and supported on the ground. There is an accommodating space 13 in the upper part of the inner shell 11 and the outer shell 12. The accommodating space 13 is arc-shaped. The two accommodating spaces 13 can be spliced ​​together to form an annular hole.

[0025] Both the inner shell 11 and the outer shell 12 are filled with thermal insulation cotton. During installation, the outer shell 12 is attached to the tree. The two layers of protection of the inner shell 11 and the outer shell 12 can keep the tree warm, reduce the impact of wind on the tree, and reduce the probability of the tree being damaged by frost.

[0026] Connecting blocks 14 are provided at both the upper and lower ends of the side of the outer shell 12. The connecting blocks 14 protrude outward from the side wall of the outer shell 12. After both inner shells 11 are attached to the tree, the connecting blocks 14 of the two outer shells 12 are at the same height. A locking screw 141 passes through the connecting blocks 14 and passes through the two outer shells 12. Due to the different diameters of the trees, there is a distance between the two connecting blocks 14. A positioning nut 142 is screwed onto the side wall of the locking screw 141. After the locking screw 141 passes through the two connecting blocks 14, the positioning nut 142 is turned to fix the position of the two bottom shells 1.

[0027] An extension rod 15 is provided on the lower part of the side wall of the outer casing 12. A guide wheel 151 is rotatably connected to the extension rod 15. The guide wheel 151 can change its orientation relative to the extension rod 15. When the guide wheel 151 rotates downward, it will contact the ground, which facilitates the movement of the bottom casing 1, saves the installer's effort, and improves installation efficiency. After the bottom casing 1 is fixed in position, the guide wheel 151 is lifted upward, so that the guide wheel 151 does not contact the ground, and the bottom casing 1 is stably installed on the ground. To prevent the guide wheel 151 from turning during movement, a limit pin 152 is detachably connected to the side wall of the extension rod 15. When the guide wheel 151 contacts the ground, the limit pin 152 is inserted, and the limit pin 152 is in contact with the top surface of the guide wheel 151. At this time, the guide wheel 151 cannot rotate upward, and the bottom casing 1 can be pulled to move.

[0028] The two bottom shells 1 have interconnected receiving spaces 13, within which a hemp rope 2 is coiled and wound. To install the hemp rope 2, simply insert one end of the rope into the bottom of the receiving space 13, and then spiral it inwards along the path within the space. The hemp rope 2 is inexpensive and provides wind and cold protection. Positioned between the inner shell 11 and the outer shell 12, the hemp rope 2 forms a third layer of protection, enhancing the device's anti-freezing effect. A gap exists between the two bottom shells 1, which is filled by the hemp rope 2, allowing the device to provide comprehensive warmth and anti-freezing for trees of different sizes.

[0029] A vertical slide rail 16 is provided at the outer shell 12, with the top of the vertical slide rail 16 penetrating through the outer shell 12. A slide rod 31 is provided on the side wall of the lifting shell 3, and the slide rod 31 is slidably connected to the vertical slide rail 16. The lifting shell 3 is slidably connected to the receiving space 13, and the bottom of the lifting shell 3 is in contact with the hemp rope 2. When installing the lifting shell 3, the slide rod 31 is placed into the vertical slide rail 16, and the main body of the lifting shell 3 is placed into the receiving space 13. The movement of the slide rod 31 along the vertical slide rail 16 restricts the lifting shell 3 to only move up and down. The bottom of the lifting shell 3 compresses the hemp rope 2 by gravity. After the hemp rope 2 is compressed, the gaps are reduced, and the windproof and cold-proof ability is further improved. The lifting shell 3 is used to increase the protective height of this device. The lifting shell 3 also contains insulation cotton. In trees with tall trunks, the bottom of the lifting shell 3 is raised using hemp rope 2. The specific height of the raising is determined individually according to the height of each tree. The lifting shell 3 protects the higher tree trunks, further improving the anti-freezing effect. The lifting shell 3 is slidably connected to the bottom shell 1, so the protective height can be changed according to the height of the tree, making it more adaptable.

[0030] Observation unit 4 is used to observe the frost damage to trees in the insulation area, such as... Figure 3As shown, the observation mechanism 4 includes an observation window 41, a sealing plug 42, a fixing plate 43, and a positioning pin 44. The observation window 41 is located on the side wall of the lifting shell 3 and is a notch in the side wall of the lifting shell 3. The sealing plug 42 is detachably connected to the observation window 41 and has the same size as the observation window 41. When not observing, the sealing plug 42 is placed in the observation window 41 to keep the tree warm. The fixing plate 43 is located at the rear end of the sealing plug 42 and is used to pull or push the observation window 41 in. The positioning pin 44 is located on the side wall of the lifting shell 3. After the sealing plug 42 is installed, the positioning pin 44 passes through the fixing plate 43. A limit nut 441 is screwed onto the positioning pin 44. The limit nut 441 fits against the fixing plate 43. After the limit nut 441 is screwed in, the sealing plug 42 will not fall off. When it is necessary to remove the sealing plug 42 for observation, the limit nut 441 is unscrewed and the fixing plate 43 is pulled backward.

[0031] There are gaps between the two lifting shells 3, and also between the top of the lifting shell 3 and the tree. These gaps can easily allow air to leak in, affecting the anti-freezing effect. Therefore, windproof stickers 5 are affixed to these gaps. The windproof stickers 5 are elastic and can be pulled apart. They are adhesive and seal the gaps between the lifting shells 3 and between the lifting shells 3 and the tree. In use, first, the windproof stickers 5 are affixed to the vertical gap between the two lifting shells 3. Then, a ring of windproof stickers 5 is wrapped around the lifting shells 3 and the tree. At this point, the vertical windproof stickers 5 are clamped and fixed, completely sealing the gaps and improving the anti-freezing performance of the device.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
