Abstract
Description
Technical Field
[0001] This utility model relates to the fields of landscaping and plant protection, and in particular to a tree antifreeze and heat-insulating wrapping device. Background Technology
[0002] Winter temperatures are low, making trees, especially young trees, susceptible to frost damage, which can hinder their growth and even lead to death. To protect trees from low temperatures, trunk wrapping is commonly used for insulation. However, traditional wrapping methods rely heavily on manual labor, using materials such as straw ropes, cloth strips, or plastic film to directly wrap the trunk. This approach has certain shortcomings in practical application. For example, straw ropes and cloth strips have limited insulation and easily absorb water and freeze, further increasing the risk of frost damage; while plastic film provides some insulation, its poor breathability can lead to bark rot or disease development with prolonged wrapping. Furthermore, existing wrapping methods are mostly for single use, lacking reusability and increasing resource waste and maintenance costs.
[0003] Meanwhile, during the wrapping process, due to the varying shapes of trees, traditional materials are difficult to apply tightly, easily loosening or falling off, significantly reducing the insulation effect. Especially in windy areas, the wrapping materials are more susceptible to environmental factors and may even fail. These problems not only reduce the actual effectiveness of frost protection and insulation but also increase the frequency and difficulty of manual maintenance, causing numerous inconveniences to tree care. Utility Model Content
[0004] The purpose of this utility model is to provide a tree antifreeze and heat-insulating wrapping device, which solves the problems mentioned in the background art.
[0005] This utility model is implemented as follows: a tree antifreeze and heat-insulating wrapping device includes a support frame, an adjustable inner lining assembly, an outer protective sleeve, and a fixing and adjustment mechanism. The support frame is a split ring structure, composed of at least two arc-shaped support plates spliced together. Adjacent arc-shaped support plates are connected by hinges and equipped with locking devices to achieve fixation after splicing. Each arc-shaped support plate has a groove on its inner side, extending along the length of the arc-shaped support plate. The adjustable inner lining assembly includes multiple elastic support strips and a flexible heat-insulating pad. The two ends of the elastic support strips are respectively embedded in the grooves and can slide within the grooves. The flexible heat-insulating pad covers the elastic support strips and is fixedly connected to the elastic support strips by Velcro. The outer protective sleeve has a double-layer structure, with an inner layer of waterproof and breathable membrane and an outer layer of weather-resistant fiber fabric. The outer protective sleeve is connected to the support frame by a zipper. The fixing and adjustment mechanism includes a tension belt and a tension wheel. The two ends of the tension belt are respectively fixed to both sides of the support frame. The tension wheel is installed on the tension belt and the tension of the tension belt is adjusted by a threaded rod.
[0006] Furthermore, it also includes heat-conducting adjustment plates; each arc-shaped support plate has a groove on its outer surface, and the heat-conducting adjustment plate is embedded in the groove and fixed with bolts; the heat-conducting adjustment plate is made of metal and has serrated protrusions on its surface to increase the friction between it and the outer protective sleeve; the number of heat-conducting adjustment plates can be adjusted according to the trunk diameter, and there is a gap between adjacent heat-conducting adjustment plates with a gap width of 5mm to 10mm.
[0007] Furthermore, the elastic support bar has a hollow structure filled with phase change energy storage material; the cross-section of the elastic support bar is elliptical, and its major axis is consistent with the radial direction of the arc-shaped support plate; both ends of the elastic support bar are equipped with buckles, which cooperate with the limiting blocks in the slide groove to prevent the elastic support bar from disengaging from the slide groove.
[0008] Furthermore, the outer surface of the flexible insulation pad is provided with a reflective coating made of aluminum foil to reflect external heat; the inner surface of the flexible insulation pad is provided with a moisture-absorbing layer made of microfiber material to absorb moisture from the surface of the tree trunk.
[0009] Furthermore, the outer protective cover has a two-way zipper with a locking device on the zipper pull, which is secured by a spring pin. The top of the outer protective cover has a drainage hole with a filter screen embedded inside to prevent debris from entering.
[0010] Furthermore, the tension belt has a multi-layer composite structure, including a nylon braided layer and a rubber interlayer, with the nylon braided layer on the outside and the rubber interlayer on the inside; the rim of the tensioning wheel is provided with anti-slip patterns, which are wavy and used to increase the friction between the tensioning belt and the anti-slip pattern.
[0011] Furthermore, it also includes positioning pins; each arc-shaped support plate has multiple positioning holes in its groove, and the positioning pins are inserted into the positioning holes and fixed by threads; the end of the positioning pin is provided with a knob, and the surface of the knob is provided with anti-slip texture.
[0012] Furthermore, the hinges of the support frame are concealed, with the hinge's rotation axis embedded in the edge of the curved support plate and secured by screws; the hinge's rotation angle ranges from 0° to 180° to accommodate tree trunks of different diameters.
[0013] Furthermore, the locking device is a quick-release structure, including a latch and a bolt. The latch is fixed to the end of one of the arc-shaped support plates, and the bolt is fixed to the end of the other arc-shaped support plate. The latch and bolt are quickly locked by a spring pin.
[0014] Furthermore, the bottom of the outer protective cover is equipped with a ventilation opening, which contains an activated carbon filter to adsorb harmful substances in the air; the opening of the ventilation opening faces downward to prevent rainwater from entering.
[0015] The beneficial effects of this utility model are as follows: By combining a split-type ring support frame with an adjustable inner lining component, the size of the wrapping device can be flexibly adjusted according to the trunk diameter to ensure a tight fit to the trunk surface and prevent loosening or falling off. At the same time, the phase change energy storage material filled inside the elastic support strip can absorb external heat during the day and release it at night, playing a role in regulating the temperature and thus improving the heat preservation effect.
[0016] The outer protective sleeve adopts a double-layer structure design. The inner waterproof and breathable membrane effectively blocks external moisture and prevents the bark from rotting, while the outer weather-resistant fiber fabric enhances the durability and wind resistance of the device. In addition, the serrated protrusions of the heat conduction adjustment plate increase the friction between it and the outer protective sleeve, further improving the stability of the device.
[0017] The reflective coating of the flexible insulation pad can reflect external heat and reduce heat loss, while the moisture-absorbing layer can absorb moisture from the surface of the tree trunk, keep the bark dry, and reduce the risk of disease growth. The design of the tension belt and tension wheel allows the device to be finely adjusted according to the shape of different tree trunks, ensuring that the wrapping device is always in a taut state and is not easily affected by the external environment and will not fail.
[0018] In summary, this utility model solves many problems existing in traditional tree antifreeze and insulation wrapping methods by combining multiple technical means, and has significant creativity, novelty and practicality. Attached Figure Description

[0023] The tree antifreeze and heat-insulating wrapping device of this utility model is as follows: Figures 1 to 3 As shown, its overall structure consists of a support frame 1, an adjustable inner lining assembly, an outer protective sleeve 6, and a fixing and adjusting mechanism. The support frame 1 is a split ring structure, composed of at least two arc-shaped support plates 2 spliced together. Adjacent arc-shaped support plates 2 are connected by hinges. The rotation axis of the hinge is embedded in the edge of the arc-shaped support plate 2 and fixed by screws. The rotation angle of the hinge is 0° to 180° to accommodate tree trunks of different diameters. Each arc-shaped support plate 2 has a locking device at its end, which includes a latch and a bolt. The latch is fixed to the end of one arc-shaped support plate 2, and the bolt is fixed to the end of the other arc-shaped support plate 2. The latch and bolt are quickly locked by a spring pin. A groove 3 is formed on the inner side of the arc-shaped support plate 2 along its length. The groove 3 is used to install the elastic support strip 4 in the adjustable inner lining assembly.
[0024] The adjustable inner lining assembly consists of multiple elastic support strips 4 and flexible insulation pads 5. The two ends of the elastic support strips 4 are embedded in grooves 3 and can slide within them. Limiting blocks are installed within the grooves 3, engaging with the snap-fit ends of the elastic support strips 4 to prevent them from detaching. The elastic support strips 4 are hollow, filled with phase change energy storage material. The cross-section of the elastic support strips 4 is elliptical, with its major axis aligned radially with the arc-shaped support plate 2. Flexible insulation pads 5 cover the elastic support strips 4 and are fixed with Velcro. The outer surface of the flexible insulation pads 5 has a reflective coating of aluminum foil, and the inner surface has a moisture-absorbing layer of microfiber material. The outer surface of the arc-shaped support plate 2 has grooves, into which heat-conducting adjustment pieces 10 are embedded and fixed with bolts. The heat-conducting adjustment pieces 10 are made of metal and have serrated protrusions on their surface. A gap of 5mm to 10mm is maintained between adjacent heat-conducting adjustment pieces 10.
[0025] The outer protective sleeve 6 has a double-layer structure. The inner layer is a waterproof and breathable membrane, and the outer layer is a weather-resistant fiber fabric. The outer protective sleeve 6 is connected to the support frame 1 via a zipper 7. The zipper 7 is a two-way zipper with a locking device on the zipper pull. The locking device uses a spring pin to secure the zipper pull. The top of the outer protective sleeve 6 has a drainage hole 11 with an embedded filter screen, and the bottom has a vent 12 with an embedded activated carbon filter screen, and the vent faces downward to prevent rainwater from entering.
[0026] The fixing and adjusting mechanism includes a tension belt 8 and a tension wheel 9. The tension belt 8 has a multi-layer composite structure, with an outer nylon braided layer and an inner rubber interlayer. Both ends of the tension belt 8 are fixed to the two sides of the support frame 1. The tension wheel 9 is mounted on the tension belt 8 and its tension is adjusted via a threaded rod. The rim of the tension wheel 9 has a wavy anti-slip texture to increase friction with the tension belt 8. Each arc-shaped support plate 2 has multiple positioning holes in its groove 3. Positioning pins are inserted into these holes and fixed by threads. A knob is located at the end of each positioning pin, and the knob surface has an anti-slip texture.
[0027] In actual operation, the support frame 1 is first unfolded around the tree trunk. The angle of the arc-shaped support plate 2 is adjusted by hinges to fit the surface of the tree trunk. Then, the adjacent arc-shaped support plates 2 are fixed to form a complete ring structure using a locking device. Next, the two ends of the elastic support strip 4 are embedded into the sliding groove 3 and the position is adjusted according to the diameter of the tree trunk. The phase change energy storage material inside the elastic support strip 4 can absorb external heat during the day and release it at night to regulate the temperature. The flexible insulation pad 5 covers the elastic support strip 4 and is fixed with Velcro. The reflective coating of the flexible insulation pad 5 reflects external heat, and the moisture-absorbing layer absorbs moisture from the surface of the tree trunk to keep the bark dry. The heat-conducting adjustment plate 10 is embedded in the groove of the arc-shaped support plate 2 and fixed with bolts. The serrated protrusions increase the friction between it and the outer protective sleeve 6. The outer protective sleeve 6 is wrapped around the outside of the support frame 1 by a zipper 7. The locking device of the zipper 7 ensures that the outer protective sleeve 6 is tightly closed. The design of the drainage hole 11 and the vent 12 ensures the breathability and waterproof performance of the device. Finally, the overall tightness of the tensioning device is adjusted by tensioning belt 8 and tensioning wheel 9 to ensure that the wrapping device fits tightly against the tree trunk surface and avoids failure due to external environmental influences.
[0028] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.
[0029] In practice, the support frame 1 is first unfolded around the tree trunk. At this point, the angle of the curved support plate 2, connected by hinges, is adjusted to ensure it can accommodate tree trunks of different diameters. The hinge's rotation axis is embedded in the edge of the curved support plate 2 and secured with screws; its rotation range of 0° to 180° allows the device to flexibly adapt to changes in the shape of the tree trunk. Once the support frame 1 is in contact with the tree trunk, the locking device quickly locks the latches and tongues at the ends of adjacent curved support plates 2. The spring pin design further enhances the ease of operation. This process ensures that the support frame 1 is firmly fixed to the tree trunk, preventing loosening due to external wind or vibration.
[0030] Next, elastic support strips 4 are installed inside the groove 3. After the two ends of the elastic support strip 4 are embedded in the groove 3, its position can be adjusted by sliding along the groove 3 according to the actual diameter of the tree trunk. The limiting blocks inside the groove 3 engage with the snap-fit at the ends of the elastic support strip 4 to prevent it from detaching from the groove 3. The phase change energy storage material filled inside the elastic support strip 4 can absorb solar radiation heat during the day and release heat when the temperature drops at night, thereby regulating the temperature around the tree trunk. This heat storage and release mechanism effectively alleviates the damage of low temperatures to the tree trunk, while avoiding the insufficient heat insulation effect caused by traditional materials that simply insulate heat.
[0031] Subsequently, the flexible insulation pad 5 is placed over the elastic support strip 4 and secured with Velcro. The outer surface of the flexible insulation pad 5 has a reflective aluminum foil coating that reflects low-temperature radiation from cold air, reducing heat loss. Its inner surface has a microfiber moisture-absorbing layer that absorbs moisture from the tree trunk, keeping the bark dry and reducing the risk of disease. This double-layer design of the flexible insulation pad 5 not only enhances insulation performance but also provides breathability and moisture resistance.
[0032] During the installation of the outer protective sleeve 6, it is wrapped around the support frame 1 using a zipper 7. The zipper 7 is a two-way design, and the zipper pull is equipped with a locking device, secured by a spring pin to ensure a tight closure of the outer protective sleeve 6. The top of the outer protective sleeve 6 has a drainage hole 11, and the bottom has a ventilation opening 12. The drainage hole 11 has an embedded filter screen to prevent debris from entering, while the ventilation opening 12 has an embedded activated carbon filter screen, which can absorb harmful substances in the air and prevent rainwater backflow. This design ensures the breathability of the internal environment of the device while avoiding the problem of bark rot caused by water accumulation or dampness.
[0033] Finally, the overall tension of the device is adjusted using the tension band 8 and tension wheel 9. The tension band 8 employs a multi-layered composite structure; the outer nylon braided layer provides high-strength support, while the inner rubber interlayer increases friction, ensuring a tight fit between the device and the tree trunk. The tension wheel 9 adjusts the tension of the tension band 8 via a threaded rod, and its wavy anti-slip texture further enhances grip. This adjustment process allows the device to be fine-tuned according to the shape of different tree trunks, thus preventing loosening or detachment due to irregular trunk shapes or external wind forces.
[0034] In summary, this utility model achieves the installation of the support frame 1, the fixing of the outer protective sleeve 6, and the functional coordination of each component through the above steps. Each step has been carefully designed to ensure that the device fits tightly against the tree trunk, provides a stable heat preservation effect, and has good air permeability and waterproof performance. These technical means work together to solve many problems existing in traditional tree antifreeze and heat preservation methods, achieving significant technical results.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
