Description

Technical Field

[0001] This utility model relates to the field of cold-proof fixing belt technology, specifically a quick-fixing belt for cold-proof wrapping of forestry seedlings. Background Technology

[0002] The forestry seedling frost protection wrapping quick-fixing strap is an auxiliary tool used to quickly and firmly fix frost protection wrapping materials. It is mainly used in scenarios where seedlings need frost protection. Its core function is to tightly wrap the frost protection material on the surface of the seedling and quickly fix it through a convenient structure to prevent the frost protection material from loosening or falling off, and to ensure stable frost protection effect. The tree insulation and cold protection wrapping structure for greening maintenance described in application number CN202322372021.3 has the following shortcomings: The device adopts a structure combining a metal frame and injection-molded parts. Wrapping the tree trunk with the frame will hinder manual inspection of bark cracks and insect eggs, as well as maintenance operations such as "scraping off cracked bark". The frame must be removed before operation, which is not very flexible. At the same time, the manufacturing cost of the metal frame and injection-molded parts is relatively high. Although it is suitable for municipal greening projects with sufficient budget, it is difficult to popularize in scenarios with limited budgets, such as nurseries or small-scale growers. Based on this, this solution proposes "a quick-fixing strap for frost protection wrapping of forestry seedlings" to solve the above problems. Utility Model Content

[0012] 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.

[0013] Please see Figure 1-8 The technical solution of this utility model includes: a strap 1, a fixing block 2, an adjusting wrench 3, a first gear 4, a second gear 5, a traction rod 6, a traction groove 7, a first traction roller 8, a second traction roller 9, a positioning block 10, a guide rod 11, a spring 12, a first pin 13, and a second pin 14. The wrapping strap 1 has six strips of cloth on its side, and the side strips are fixedly connected to two symmetrically distributed traction rods 6. The traction rods 6 are made of hard plastic, which can enhance the connection stability with the wrapping strap 1 and ensure the balanced transmission of traction force. The wrapping strap 1 is woven from multi-layer composite heat insulation cloth, which can enhance the cold protection and heat insulation effect and provide reliable protection for seedlings. The traction rod 6 on the right side of the strap 1 is engaged in the traction groove 7 of the first traction roller 8, and the traction rod 6 on the left side is engaged in the traction groove 7 of the second traction roller 9. The engaging structure can prevent slippage during traction. The first traction roller 8 and the second traction roller 9 are rotatably connected to both sides of the fixed block 2, and the two have the same structure, which can realize the two tractions of the strap 1, ensure uniform force during tightening, and avoid local damage to the seedlings. The first gear 4 is fixedly connected to the upper shaft end of the first traction roller 8, and the second gear 5 is fixedly connected to the lower shaft end. The first gear 4 and the second gear 5 have the same structure, which can ensure stable power transmission. An adjustment wrench 3 is installed below the second gear 5, which makes it easy for the operator to flexibly control the rotation of the traction roller, realize the precise adjustment of the tightness of the wrapping tape 1, and improve the ease of operation. The upper surface of the fixing block 2 is fixedly connected to the positioning block 10, and the two sides of the positioning block 10 are fixedly connected to the guide rods 11. The guide rods 11 are fitted with springs 12 on the outside. The right side of the guide rods 11 is slidably connected to the first pin 13, and the left side is slidably connected to the second pin 14. This structure can provide sliding guidance and automatic reset function for the first pin 13 and the second pin 14. It can quickly lock after the fixing belt is tightened to prevent the structure from loosening and improve the safety and reliability of use.

[0014] Working principle: When using a forestry seedling cold protection wrapping quick fixing strap, first wrap the strap 1 around the seedling that needs cold protection. Utilize the characteristics of its multi-layer composite insulation cloth to initially form a cold protection wrapping layer. At this time, the two symmetrically distributed rigid plastic traction rods 6 on the side of the strap 1 respectively connect with the traction structure in the fixing block 2 - the right traction rod 6 is inserted into the traction groove 7 of the first traction roller 8, and the left traction rod 6 is inserted into the traction groove 7 of the second traction roller 9. The interlocking structure ensures that there is no slippage during traction. The operator rotates the adjusting wrench 3, which is mounted below the second gear 5, to drive the second gear 5 and the first traction roller 8, which is fixedly connected to it, to rotate. When the traction roller rotates, it generates a pulling force on the traction rod 6 through the traction groove 7, which causes the wrapping strap 1 to tighten. Because the traction structures on both sides are symmetrical, the wrapping strap 1 is evenly stressed when it wraps around the seedling, avoiding local overtightness that could damage the seedling. When the strap 1 is tightened to the appropriate tightness, the first pin 13 and the second pin 14 on the guide rods 11 on both sides of the positioning block 10 automatically reset under the elastic force of the spring 12 and insert into the corresponding locking position, restricting the traction roller from reversing, thereby firmly locking the tightened state of the strap 1 and preventing the package from failing due to structural loosening.

[0015] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
