Description

Technical Field

[0001] This utility model relates to the field of agricultural rain shelter technology, specifically to a metal wire fixing structure for agricultural rain shelters. Background Technology

[0002] like Figure 1 As shown, the frame structure of a rain shelter for crops (vegetables, fruit trees, etc.) includes several arched support frames 01 arranged at intervals along the length of the rain shelter. Metal wires 02 (usually steel wires) are connected between the support frames 01 to increase the overall structural stability. The rain-shielding membrane is fixed to the top of the frame structure. In existing technology, when constructing a rain shelter, the metal wires are tied and fixed to the support frames to achieve the connection between the metal wires and the support frames. This tying and fixing operation is cumbersome, time-consuming, and labor-intensive, especially when there are many support frames and a large number of tying points, which seriously affects the construction efficiency of the rain shelter. Utility Model Content

[0003] The purpose of this utility model is to address the problem that fixing metal wires to the support frame by binding is a cumbersome, time-consuming, and labor-intensive process that affects the efficiency of building agricultural rain shelters, in the existing technology. This invention provides a metal wire fixing structure for agricultural rain shelters.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A wire fixing structure for an agricultural rain shelter includes a wire and a support frame, a conical cylinder, and a cylindrical cylinder fixedly connected to the support frame. The central axis of the cylindrical cylinder is along the length of the rain shelter. The inner diameter of the cylindrical cylinder is larger than the outer diameter of the small end of the conical cylinder and smaller than the outer diameter of the large end of the conical cylinder. A notch is provided on the small end of the conical cylinder, and the length of the notch is parallel to the central axis of the conical cylinder. The wire passes through the central hole of the conical cylinder and the cylindrical cylinder, with the small end of the conical cylinder facing the cylindrical cylinder. The conical cylinder can slide along the wire, and when the conical cylinder slides to abut against the cylindrical cylinder, the length of the portion inserted into the cylindrical cylinder is less than the length of the notch. The conical cylinder can be pushed in by an external force until its small end is clamped inside the cylindrical cylinder, and during the pushing process, the small end gradually contracts to press against the wire.

[0006] In this utility model employing the aforementioned technical solution, when it is necessary to fix the metal wire to the support frame, the metal wire is first passed through the conical cylinder and the cylindrical cylinder. Then, the conical cylinder is slid until it abuts against the cylindrical cylinder. Afterward, the operator pushes the conical cylinder into the cylindrical cylinder with external force. The small end of the conical cylinder deforms, the notch gradually shrinks, and the small end gradually contracts. The small end of the conical cylinder and the cylindrical cylinder are squeezed together, and the friction between them ensures that the conical cylinder remains firmly stuck inside the cylindrical cylinder after the pushing force is removed. At this time, the small end of the conical cylinder has contracted and pressed the metal wire. Thus, the metal wire is fixed. Compared with the existing technology of fixing the metal wire to the support frame by binding when building a rain shelter for crops, which is cumbersome, time-consuming, and labor-intensive, affecting the construction efficiency of the rain shelter, this utility model only requires the operator to push the conical cylinder to clamp it inside the cylindrical cylinder to fix the metal wire. Compared with the method of binding the metal wire, the operation is simpler, saves time and labor, and the construction efficiency of the rain shelter is higher.

[0007] Furthermore, the notch is U-shaped; setting the notch in a U-shape avoids stress concentration at the bottom of the notch, which could cause damage to the conical cylinder.

[0008] Furthermore, the taper of the conical cylinder is 5° to 7°. If the taper of the conical cylinder is too large, it cannot be tightly clamped inside the cylindrical cylinder; if the taper of the conical cylinder is too small, the deformation of its small end is too small to clamp the metal wire. By adopting the aforementioned taper of the conical cylinder, it can be ensured that after the conical cylinder is pushed into the cylindrical cylinder, the conical cylinder is still clamped inside the cylindrical cylinder after the thrust is released, and it can also be ensured that the deformation and contraction of the small end is sufficient to clamp the metal wire.

[0009] Furthermore, the conical cylinder is made of aluminum, copper, or rubber; the cylindrical cylinder is made of steel. The cylindrical cylinder is made of a harder material, while the conical cylinder is made of a relatively softer material, making it easier to deform and be pushed in and locked inside the cylindrical cylinder.

[0010] Furthermore, the metal wire is steel wire or iron wire; steel wire or iron wire has a better load-bearing effect on the rain shelter.

[0011] Furthermore, it also includes a base, which is fixedly connected to the support frame; the cylindrical tube is fixedly connected to the base; the cylindrical tube is indirectly fixedly connected to the support frame through the base, and the base can be set to a shape that fits the support frame, making the connection more secure.

[0012] Furthermore, the base includes a base plate and two vertical plates fixed to the base plate, the two vertical plates being arranged in parallel; a U-shaped groove is formed between the base plate and the two vertical plates, the length of the U-shaped groove being along the length of the rain shelter; a cylindrical tube is provided in the middle area of ​​the top of each of the two vertical plates; this arrangement allows two parallel metal wires to be fixed, and a U-shaped guide rail can be suspended through the two metal wires, the ends of the U-shaped guide rails overlapping in the U-shaped groove, and a slider is provided in the U-shaped guide rails to connect with the side of the rain shelter, allowing the rain shelter to be moved and retracted.

[0013] Furthermore, the base plate is provided with several connection holes for use with bolts to bolt the base to the support frame; the bolt connection ensures a stable and reliable structure.

[0014] Furthermore, a rib is provided between the side of any of the upright plates away from the U-shaped groove and the base plate; the rib can increase the structural strength of the base.

[0015] Compared with the existing technology, the advantages of this utility model are: the metal wire can be fixed by simply having the operator push the conical cylinder to clamp it in the cylindrical cylinder. Compared with the method of tying the metal wire, the operation is simpler, saves time and effort, and the construction efficiency of the rain shelter is higher. Attached image description:

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This embodiment provides a wire fixing structure for agricultural rain shelters, such as... Figures 2-4As shown, the canopy includes a metal wire 2 and a support frame 1, a conical cylinder 3, and a cylindrical cylinder 4 fixedly connected to the support frame. The central axis of the cylindrical cylinder 4 is along the length of the canopy. The inner diameter of the cylindrical cylinder 4 is larger than the outer diameter of the small end of the conical cylinder 3 and smaller than the outer diameter of the large end of the conical cylinder 3. A notch 5 is provided on the small end of the conical cylinder 3, and the length of the notch 5 is parallel to the central axis of the conical cylinder. The metal wire passes through the central hole of the conical cylinder 3 and the cylindrical cylinder 4, with the small end of the conical cylinder facing the cylindrical cylinder. The conical cylinder 3 can slide along the metal wire. When the conical cylinder 3 slides to abut against the cylindrical cylinder, the length of the part inserted into the cylindrical cylinder 4 is less than the length of the notch 5. The conical cylinder 3 can be pushed in by external force until its small end is clamped in the cylindrical cylinder 4, and during the pushing process, the small end gradually contracts to press against the metal wire 2. The notch 5 is U-shaped.

[0024] The taper of conical cylinder 3 is 5° to 7°;

[0025] The conical cylinder 3 is made of aluminum, copper, or rubber; the cylindrical cylinder 4 is made of steel.

[0026] Metal wire 2 is steel wire or iron wire;

[0027] It also includes a base, which is fixedly connected to the support frame 1; a cylindrical tube 4 is fixedly connected to the base; the base includes a bottom plate 6 and two upright plates 7 that are vertically fixed on the bottom plate 6, and the two upright plates 7 are arranged in parallel; a U-shaped groove is formed between the bottom plate 6 and the two upright plates 7, and the length direction of the U-shaped groove is along the length direction of the rain shelter; a cylindrical tube 4 is provided in the middle area of ​​the top of each of the two upright plates 7.

[0028] The base plate 6 is provided with a number of connection holes 8 for use with bolts to connect the base to the support frame 1; in this embodiment, the base plate 6 is provided with two connection holes 8 on each side of the U-shaped groove.

[0029] A rib 9 is connected between the side of any upright plate 7 away from the U-shaped groove and the bottom plate 6.

[0030] In this utility model employing the aforementioned technical solution, when it is necessary to fix the metal wire 2 to the support frame 1, the metal wire 2 is first passed through the conical cylinder 3 and the cylindrical cylinder 4. Then, the conical cylinder 3 is slid until it abuts against the cylindrical cylinder 4. Afterward, the operator pushes the conical cylinder 3 into the cylindrical cylinder 4 using external force (either by hand or by striking with a tool). The small end of the conical cylinder 3 deforms, the notch 5 gradually shrinks, and the small end gradually contracts. Extrusion occurs between the small end of the conical cylinder 3 and the cylindrical cylinder 4. The friction between the two causes the conical cylinder to deform after the pushing force is removed. The conical tube 3 remains firmly inside the cylindrical tube 4, and at this time, the small end of the conical tube 3 has contracted and pressed the metal wire 2; thus, the metal wire 2 is fixed. Compared with the existing technology of fixing the metal wire to the support frame by binding when building a rain shelter for crops, which is more cumbersome, time-consuming and labor-intensive, affecting the construction efficiency of the rain shelter, this utility model only requires the operator to push the conical tube to be clamped inside the cylindrical tube to fix the metal wire. Compared with the method of binding the metal wire, the operation is simpler, saves time and labor, and the construction efficiency of the rain shelter is higher.
