Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, and in particular to a frost-resistant device for landscaping seedlings. Background Technology

[0002] With the acceleration of modern urbanization, people have increasingly higher demands for urban greening. Therefore, tree transplantation is becoming more and more frequent. Since the root system of trees inevitably suffers some damage during transplantation, it is essential to protect transplanted trees, especially by protecting them from cold and moisture. Doing a good job in this regard plays a crucial role in ensuring the survival rate of transplanted trees.

[0003] The patent document CN203057967U, concerning a tree cold-proofing and moisture-retaining device, includes: a straw rope wrapped around the tree trunk, with multiple bamboo boards evenly arranged on the outer side of the straw rope, the concave surfaces of the bamboo boards facing inwards; the bamboo boards are fixed to the tree trunk with iron nails; the bamboo boards extend downwards from the middle or upper part of the straw rope and are inserted into the soil. In this tree cold-proofing and moisture-retaining device, the straw rope is generally wrapped horizontally around the tree trunk, but the bamboo strips and boards are arranged vertically. During rain or watering, the vertically arranged bamboo strips and boards can accelerate the downward flow of water, thereby reducing water penetration into the straw rope and preventing mold and rot. The bamboo boards are fixed to the tree trunk wrapped with straw rope by iron nails, interrupting the continuity of the straw rope and preventing the entire straw rope from falling off due to breakage at a certain point. These measures can extend the service life of the straw rope, making it more effective at retaining moisture. This achieves the goal of saving material and labor costs. However, the above patent document still has the following defects in its implementation:

[0004] This device only uses straw ropes and bamboo boards to protect trees from freezing and keep them warm. However, during use, there are many gaps between the straw ropes, which not only allow cold air to easily pass through the gaps and take away the heat from the tree trunk, reducing the insulation effect of the device, but also allow wind and snow to penetrate more easily. When snowflakes accumulate on the tree trunk through the gaps, they will freeze directly on the surface of the tree trunk in low-temperature environments, increasing the risk of frost damage to the tree trunk. Therefore, we propose a frost-resistant device for landscaping seedlings to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a frost-resistant device for landscaping seedlings, which can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, such as Figure 1-5As shown, a frost-resistant device for landscaping seedlings includes a connecting frame 1, wherein there are two connecting frames 1, the inner walls of the two connecting frames 1 are in close contact with the tree trunk 11, the inner surfaces of the two connecting frames 1 are fixedly connected with insulation cotton 12, the interior of the two connecting frames 1 is provided with insulation components 3, and the top and bottom of the two connecting frames 1 are provided with two installation components 2.

[0026] Specifically, in order to achieve the goal of covering the gaps in the device, see [reference needed]. Figure 4 and Figure 5 In this embodiment, the two heat insulation components 3 are symmetrically arranged with the center of the tree trunk 11. The heat insulation component 3 includes four arc-shaped rods 31. The inner surfaces of the two connecting frames 1 are provided with four grooves 32. The left and right sides of the four arc-shaped rods 31 are fixedly connected to the inner wall of the grooves 32 on the same side.

[0027] Further reading Figure 4 In this embodiment, sliders 33 are slidably connected to the outer surfaces of the four arc-shaped rods 31. Two windproof cloths 34 are provided on the side of the connecting frame 1 away from the trunk 11. The two windproof cloths 34 are symmetrically arranged with the center of the connecting frame 1. A connecting rod 331 is fixedly connected to the end of the windproof cloth 34 near the center of the connecting frame 1. The top and bottom of the connecting rod 331 are fixedly connected to the end of the slider 33 on the same side near the center of the connecting frame 1.

[0028] Further reading Figure 5 In this embodiment, spring 2 311 is sleeved on the outer surface of each of the four arc-shaped rods 31. The end of each of the four spring 2 311 near the center of the connecting frame 1 is fixedly connected to the end of the slider 33 on the same side away from the center of the connecting frame 1. The end of each of the four spring 2 311 away from the center of the connecting frame 1 is fixedly connected to the inner wall of the groove 1 32 on the same side.

[0029] Further reading Figure 5 In this embodiment, the two windproof cloths 34 on the front are fixedly connected with Velcro tabs 341 at the ends away from the center of the tree trunk 11, and the two Velcro tabs 341 on the back are fixedly connected with Velcro tabs 342 at the ends near the center of the tree trunk 11.

[0030] During implementation, after the two connecting frames 1 are installed, a certain gap will exist between the two connecting frames 1 due to the thickness of the tree trunk. By pulling all four windproof cloths 34 towards the gap on the same side, when the two windproof cloths 34 on the same side are pulled to a certain distance, the ends of the two windproof cloths 34 on the front away from the center of the tree trunk 11 are fixed with Velcro fasteners 341, and the ends of the two windproof cloths 34 on the back near the center of the tree trunk 11 are fixed with Velcro fasteners 342. When the two windproof cloths 34 on the same side are pulled to a certain distance, the Velcro fasteners 341 and Velcro fasteners 342 can be used to secure the two windproof cloths 34. When the two windproof cloths 34 are fixed together, pulling the windproof cloth 34 will cause the connecting rod 331 to move. When the connecting rod 331 moves, it will cause the two sliders 33 to slide on the outer surface of the corresponding arc rod 31. When the sliders 33 slide, they will compress the second spring 311 and cause it to deform. When the two windproof cloths 34 are fixed together, the deformed second spring 311 will pull the windproof cloth 34 to move, so that it can cover the gap between the two connecting frames 1. This not only prevents cold air from contacting the tree trunk through the gap and taking away the heat of the tree trunk, thus improving the heat preservation effect of the device, but also prevents snowflakes from accumulating on the tree surface and avoids damage to the tree caused by the refreezing of the melted snow.

[0031] Example 2: This example sets up the installation components based on Example 1.

[0032] Specifically, to achieve the goal of quick and easy installation and disassembly of the device, please refer to... Figure 2 and Figure 3 In this embodiment, the mounting component 2 includes two connecting blocks 21. One end of each connecting block 21 near the center of the connecting frame 1 on the same side is fixedly connected to the surface of the connecting frame 1 on the same side. Each connecting block 21 is slidably connected with a sliding rod 22.

[0033] Further reading Figure 3 In this embodiment, the outer surface of the slide rod 22 is threaded, and a nut 23 is threadedly connected to the outer surface of the slide rod 22. The front of the nut 23 contacts the back of the connecting block 21 located on the same side of the back. A limiting block 24 is fixedly connected to the outer surface of the slide rod 22, and the front of the limiting block 24 contacts the back of the connecting block 21 located on the same side of the front.

[0034] Further reading Figure 3 In this embodiment, a fixing block 25 is fixedly connected to the front of the slide rod 22, and a spring 251 is sleeved on the outer surface of the slide rod 22. The front of the spring 251 is fixedly connected to the back of the fixing block 25, and the back of the spring 251 is fixedly connected to the front of the connecting block 21 located on the same side of the front.

[0035] During implementation, firstly, the two connecting brackets 1 are attached to the surface of the tree trunk 11. After the two connecting brackets 1 are attached, several sliding rods 22 are pushed to slide backward in the inner wall of the connecting block 21 located on the front side of the same side. After the sliding rods 22 slide a certain distance, their backs will pass through the inner wall of the connecting block 21 located on the back side of the same side. During the sliding process, the sliding rods 22 will compress the spring 251, causing it to deform. The two connecting brackets 1 can be fixed to the surface of the tree trunk 11 by turning the nut 23 clockwise. When the device is no longer needed, it can be removed by rotating the nut 23 counterclockwise. The deformed spring 251 will push the slide bar 22 to slide forward in the inner wall of the two connecting blocks 21 on the same side due to the elastic force, so that it releases the restriction on the two connecting frames 1, allowing the device to be quickly removed from the tree trunk surface for multiple uses. Not only can the device be installed on a large number of seedlings in a short time, but it can also be removed in time after the cold wave ends, without affecting the growth of seedlings and landscape effect under normal weather conditions, thus improving the practicality of the device. Moreover, the ability to be used multiple times means that it is not necessary to repurchase a large amount of materials every winter, thus improving the economy and environmental protection of the device.

[0036] The working principle of this utility model is as follows: When the device needs to be installed on the surface of a tree trunk, firstly, two connecting brackets 1 are attached to the surface of the tree trunk 11. After the two connecting brackets 1 are attached, several sliding rods 22 are pushed to slide backward in the inner wall of the connecting block 21 located on the front side of the same side. After the sliding rods 22 slide a certain distance, their backs will pass through the inner wall of the connecting block 21 located on the back side of the same side. During the sliding process, the sliding rods 22 will compress the spring 251, causing it to deform. By turning the nut 23 clockwise, the two connecting brackets 1 can be fixed to the surface of the tree trunk 11. When the device is no longer needed, it can be removed by rotating the nut 23 counterclockwise. The spring 251, due to its elastic force, pushes the slide bar 22 to slide forward within the inner walls of the two connecting blocks 21 on the same side, releasing it from the restriction on the two connecting frames 1. This allows the device to be quickly removed from the tree trunk surface for multiple uses. Not only can the device be installed on a large number of seedlings in a short time, but it can also be removed promptly after a cold snap, without affecting the growth of the seedlings or the landscape effect under normal weather conditions, thus improving the device's practicality. Furthermore, its reusability means that it eliminates the need to purchase large quantities of materials every winter, improving the device's economy and environmental friendliness. Once the two connecting frames 1 are installed, they will slide forward along with the tree trunk. The thickness of the trunk results in a gap between the two connecting frames 1. By pulling all four windproof cloths 34 towards the gap on the same side, when the two windproof cloths 34 on the same side are pulled to a certain distance, the ends of the two windproof cloths 34 on the front away from the center of the trunk 11 are fixed with Velcro fasteners 341, and the ends of the two windproof cloths 34 on the back near the center of the trunk 11 are fixed with Velcro fasteners 342. When the two windproof cloths 34 on the same side are pulled to a certain distance, the Velcro fasteners 341 and Velcro fasteners 342 can fix the two windproof cloths 34 together. The connecting rod 331 will move, and when the connecting rod 331 moves, it will cause the two sliders 33 to slide on the outer surface of the corresponding arc rod 31. When the sliders 33 slide, they will compress the second spring 311 and cause it to deform. When the two windproof cloths 34 are fixed together, the deformed second spring 311 will pull the windproof cloth 34 to move, so that it can cover the gap between the two connecting frames 1. This not only prevents cold air from contacting the tree trunk through the gap and taking away the heat of the tree trunk, thus improving the heat preservation effect of the device, but also prevents snowflakes from accumulating on the tree surface and avoids damage to the tree caused by the refreezing after the snow melts.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
