Description

Technical Field

[0001] This utility model is an insect repellent release device, belonging to the forestry field. Background Technology

[0002] In modern tree pest and disease control, to prevent pests from climbing up the trunk and threatening the tree's health, a common practice is to wrap plastic strips around the trunk as a physical control method, combined with chemical control measures, such as hanging insecticide bags on the surface of the barrier strips. The pesticide in the bags is continuously released, forming an insecticidal circle around the plastic strips. This two-pronged approach effectively prevents pests from climbing up the trunk.

[0003] Plastic strips, with their smooth surface, physically hinder pests from climbing, and their adhesive layer allows them to adhere end to end, tightly wrapping around the trunk and effectively blocking pests' climbing paths. However, as trees grow, their trunks thicken, and these tightly fitting plastic strips, lacking elasticity and scalability, cannot adapt to the trunk's increasing thickness. Over time, they are highly likely to break. Once the plastic strip breaks, not only is it difficult to maintain the insecticide bag, rendering the protective ring ineffective, but pests also regain their climbing channels, significantly impacting pest control effectiveness and increasing the cost and difficulty of pest control efforts. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an insect repellent release device to solve the problems mentioned in the background art. This utility model prevents the plastic strip from being torn by the growth of tree branches and extends the service life of the plastic strip.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an insect repellent release device, comprising a plastic strip, wherein a plastic bag for storing insect repellent is glued to the upper outer surface of the plastic strip, the outer surface of the plastic bag is evenly provided with a plurality of small holes, and a plastic sheet is provided on the outer side of the plastic strip for covering the gap between the two ends of the plastic strip, both ends of the plastic sheet are bent to form a cylindrical insertion part, and both sides of the plastic sheet are provided with straight tubes, the straight tubes being connected to the insertion part through a connector.

[0006] Furthermore, the connector includes an elastic rubber band, which is inserted into the straight tube in a stretched state. Connecting rods are installed at both ends of the elastic rubber band. One end of each connecting rod is slidably installed inside the straight tube, and the other end is inserted into the connector. Both ends of the straight tube are provided with blocking rings, which are respectively sleeved on the two connecting rods and connected and fixed to them. Two elastic bands are installed on the outer surface of the straight tube, and a thin rod is inserted into the end of each elastic band away from the straight tube. Multiple upper limit sleeves are evenly installed at the middle of the outer surface of the plastic strip, and multiple lower limit sleeves that cooperate with the upper limit sleeves are evenly installed at the lower part of the outer surface of the plastic strip. The bottom of the lower limit sleeve is closed, and the thin rod is inserted into the upper limit sleeve, with its lower end inserted into the lower limit sleeve.

[0007] Furthermore, the end of the elastic band away from the straight tube is machined with a socket, and the thin rod is inserted into the socket.

[0008] Furthermore, two tube heads are fixedly connected to the outer surface of the straight tube, and the end of the elastic band away from the insertion hole is glued to the inside of the tube head.

[0009] Furthermore, a lower plastic strip is glued to the lower part of the outer surface of the plastic strip, and multiple lower limit sleeves are evenly glued to the outer surface of the lower plastic strip.

[0010] Furthermore, an upper plastic strip is glued to the middle of the outer surface of the plastic strip, and multiple upper limit sleeves are evenly glued to the outer surface of the upper plastic strip.

[0011] Furthermore, a blind hole is provided at the position where the elastic rubber strip is installed on the connecting rod, and the end of the elastic rubber strip is glued into the blind hole.

[0012] The beneficial effects of this utility model are:

[0013] 1. The elastic rubber band is stretched inside the straight tube. Under the action of the elastic rubber band's rebound force, the two blocking rings contact the two ends of the straight tube respectively, so that one end of the two connecting rods is always inside the straight tube, shortening the length of the connecting rods inserted into the straight tube. Then, the other end of the connecting rod is inserted into the insertion part. Under the action of the two connecting rods, the straight tube and the plastic sheet are assembled, making it easy to store the straight tube and the plastic sheet separately.

[0014] 2. Wrap the plastic strip around the tree trunk, then cover the gap between the two ends of the plastic strip with a plastic sheet. Next, insert the thin rod at one end of the elastic band into the channel formed by the upper and lower limit sleeves. At this time, the elastic band is in a stretched state. Under the action of the elastic band's rebound force, the structure formed by the plastic strip and the plastic sheet is restricted to the tree trunk. As the tree trunk grows thicker, the degree of stretching of the elastic band gradually increases, thereby reducing the overlap area between the plastic sheet and the plastic strip. This prevents the plastic strip from being torn by the growth of the tree branches and extends the service life of the plastic strip. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an insect repellent release device, including a plastic belt 1, with a plastic bag 15 glued to the upper outer surface of the plastic belt 1. The outer surface of the plastic bag 15 has a plurality of small holes 16 evenly distributed, so that the insect repellent bag is stored in the space formed by the plastic bag 15 and the plastic belt 1, providing storage space for the insect repellent bag. The medicine in the insect repellent bag diffuses through the small holes 16 to realize the release of the insect repellent.

[0023] See Figures 1-4 The plastic strip 1 has a plastic sheet 8 on its outer side to cover the gap between its two ends. Both ends of the plastic sheet 8 are bent to form a cylindrical insertion part 11. Straight tubes 10 are provided on both sides of the plastic sheet 8. An elastic rubber strip 14 in a stretched state is inserted into each straight tube 10. Connecting rods 9 are installed at both ends of the elastic rubber strip 14. Blind holes are provided at the positions where the connecting rods 9 are installed with the elastic rubber strip 14, allowing the ends of the elastic rubber strip 14 to be glued into the blind holes, improving the stability of the connection between the elastic rubber strip 14 and the connecting rods 9. One end of the connecting rod 9 is slidably installed inside the straight tube 10, and the other end is inserted into the insertion part 11. Both ends of the tube 10 are provided with blocking rings 13. The two blocking rings 13 are respectively sleeved on the two connecting rods 9 and connected and fixed to the connecting rods 9, so that the elastic rubber band 14 is in a stretched state inside the straight tube 10. Then, under the action of the elastic rubber band 14, the two blocking rings 13 contact the two ends of the straight tube 10 respectively, so that one end of the two connecting rods 9 is always inside the straight tube 10, and the length of the connecting rod 9 inserted into the straight tube 10 is shortened. Then, the other end of the connecting rod 9 is inserted into the insertion part 11. Then, under the action of the two connecting rods 9, the straight tube 10 and the plastic sheet 8 are assembled, which facilitates the separate storage of the straight tube 10 and the plastic sheet 8.

[0024] See Figure 1 and Figure 2 A lower plastic strip 2 is glued to the lower part of the outer surface of the plastic strip 1. Multiple lower limit sleeves 3 are evenly glued to the outer surface of the lower plastic strip 2. The bottom of the lower limit sleeves 3 is closed. The lower plastic strip 2 increases the connection range between the lower limit sleeves 3 and the plastic strip 1. An upper plastic strip 4 is glued to the middle part of the outer surface of the plastic strip 1. Multiple upper limit sleeves 5 that cooperate with the lower limit sleeves 3 are evenly glued to the outer surface of the upper plastic strip 4. The upper plastic strip 4 increases the connection range between the upper limit sleeves 5 and the plastic strip 1.

[0025] See Figures 1-4Two elastic bands 7 are installed on the outer surface of the straight tube 10. Two tube heads 12 are fixed to the outer surface of the straight tube 10. The ends of the elastic bands 7 away from the insertion holes are glued to the tube heads 12 to improve the stability of the connection between the elastic bands 7 and the straight tube 10. A thin rod 6 is inserted into the insertion hole at the end of the elastic band 7 away from the straight tube 10. The thin rod 6 is inserted into the upper limit sleeve 5, and the lower end of the thin rod 6 is inserted into the lower limit sleeve 3. The plastic strip 1 is wrapped around the tree trunk, and then the plastic sheet 8 covers the two ends of the plastic strip 1. At the gap between the elastic band 7, the thin rod 6 inserted at one end is inserted into the channel formed by the upper limit sleeve 5 and the lower limit sleeve 3. At this time, the elastic band 7 is in a stretched state. Under the action of the elastic band 7's rebound force, the structure formed by the plastic strip 1 and the plastic sheet 8 is restricted to the tree trunk. As the tree trunk grows thicker, the degree of stretching of the elastic band 7 gradually increases, thereby reducing the overlap area between the plastic sheet 8 and the plastic strip 1, preventing the plastic strip 1 from being torn by the growth of the tree branches and extending the service life of the plastic strip 1.
