[0041] Example 1

[0042] This embodiment provides, for example Figures 1-5An adjustable hail net support bracket is shown, including a support frame 1, and a telescopic component 2 is provided under the support frame 1;

[0043] A lifting component 3 is fixedly installed on the telescopic component 2;

[0044] The bottom end of the telescopic component 2 is fixedly provided with a pre-embedded component 4;

[0045] The telescopic component 2 serves as the lifting and support structure at the lower end of the support frame 1. It rises and falls by being driven by the lifting component 3, thereby changing the overall height of the hail net support to adapt to crops of different heights. This changes the situation where the hail net is too high and does not provide adequate protection when it is placed in advance in the early stage of crop growth. The pre-embedded component 4 is embedded in the ground. Compared with the traditional concrete structure, it ensures the stability of the overall hail net support while the structural design makes it easy to replace later.

[0046] Furthermore, such as Figure 1 As shown, the support frame 1 includes a horizontal bar 12, a central bar 11, and a diagonal bar 13;

[0047] The crossbar 12 is fixedly connected to the center bar 11;

[0048] One end of the diagonal bar 13 is fixedly connected to the horizontal bar 12, and the other end is fixedly connected to the central bar 11;

[0049] The support frame 1 serves as the support structure for installing the hail protection net. By designing the height of the support frame 1 uniformly and installing it on the telescopic component 2, it is no longer necessary to customize support frames 1 of different lengths according to different customer needs before leaving the factory. At the same time, the shorter length of the center rod 11 also makes the on-site installation and layout work more convenient.

[0050] Furthermore, the telescopic component 2 includes an outer rod 21 and an inner rod 22, with the inner rod 22 sleeved on the outer rod 21, and the inner rod 22 can slide up and down in the outer rod 21;

[0051] The inner rod 22 is fixedly connected to the center rod 11. Specifically, the top end of the inner rod 22 is connected to the bottom end of the center rod 11 through a flange. During on-site installation, the center rod 11 of the support frame 1 is first connected to the inner rod 22 through a flange. Then, the height of the entire support frame 1 can be increased by raising the height of the inner rod 22.

[0052] Multiple through positioning holes 23 are longitudinally provided on the inner rod 22. Two positioning rods 24 are fitted on the positioning holes 23. By inserting the positioning rods 24 into the positioning holes 23, the inner rod 22 is locked and positioned after its height is raised. At the same time, the positioning rods 24 also serve to support the inner rod 22.

[0053] The upper end face of the outer rod 21 is provided with a mounting groove 212 that matches the positioning rod 24. The mounting groove 212 is used to place the positioning rod 24. When the telescopic assembly 2 reaches the required height, the positioning rod 24 is inserted into the positioning hole 23 at the target height and slowly lowered into the mounting groove 212. At the same time, the mounting groove 212 can better place the positioning rod 24, making the telescopic assembly 2 more stable and reliable, and also preventing the inner rod 22 from rotating or wobbling.

[0054] The telescopic assembly 2 is raised by installing two positioning rods 24. In the initial state, the first positioning rod 24 is located in the mounting groove 212. After being raised by the lifting assembly 3, the lower positioning hole 23 will appear. At this time, the second positioning rod 24 is inserted into the lowermost positioning hole 23 and the lifting assembly 3 is lowered so that the second positioning rod 24 falls into the mounting groove 212. Then the first positioning rod 24 is pulled out. By repeating this cycle, the height of the telescopic assembly 2 can be raised.

[0055] Furthermore, such as Figure 2 and Figure 3 As shown, a horizontal limiting plate 211 is fixedly installed inside the outer rod 21. The limiting plate 211 is the bottom limiting structure of the outer rod 21. That is, the lowest height of the inner rod 22 is the height when the lower end contacts the limiting plate 211, which is used to prevent the inner rod 22 from sliding down.

[0056] A vertical limiting groove 25 is provided on the inner right side of the outer rod 21. A limiting rod 26 matching the limiting groove 25 is provided on the inner rod 22. The limiting rod 26 slides in the limiting groove 25. Through the cooperation between the limiting rod 26 and the limiting groove 25, the inner rod 22 is prevented from rotating in the outer rod 21, which would affect the rising and falling action and the reliability of the structure. At the same time, the limiting groove 25 is opened on the right side of the outer rod 21 to ensure that the positioning hole is always in the front and rear direction when the inner rod 21 is installed, which is more convenient for on-site operation.

[0057] Furthermore, the positioning holes 23 are evenly spaced along the length of the inner rod 22. The evenly spaced positioning holes 23 allow the lifting distance to be roughly determined by the number of holes raised during the lifting process of the inner rod 22. At the same time, during the lifting operation, a fixed number of holes can be raised with one press. For example, the number of holes raised by one action can be adjusted by pressing down the lifting component 3. Therefore, during the initial lifting, the positioning rod 24 can be inserted across the interval to achieve the purpose of quickly raising the height. When the height is close, the positioning rod 24 is inserted next to the next hole to adjust the height more accurately.

[0058] The positioning rod 24 passes through the positioning hole 23, meaning that the length of the positioning rod 24 is greater than the length of the positioning hole 23 and both ends extend out of the positioning hole 23, so that the lifting component 3 can directly lock the positioning rod 24 to complete the raising and lowering action of the telescopic component 2.

[0059] Furthermore, such as Figure 2 and Figure 4 As shown, the lifting assembly 3 includes a mounting base 31 and a handle 32, with the mounting base 31 fixedly connected to the outer rod 21;

[0060] A connecting rod 35 is hinged to the right side of the handle 32. The hinge point between the connecting rod 35 and the handle 32 is the rotation point of the handle 32 and also serves as the force support point of the handle 32. The connecting rod 35 and the handle 32 cooperate to form a lever structure. The handle 32 on the left side of the connecting rod 35 forms a longer torque structure, making it easier to operate. The handle 32 is hinged to the mounting base 31 through the connecting rod 35. When not in use, the handle 32 can be lowered and hung on the mounting base 31.

[0061] A concave locking block 33 is fixedly provided at the head end of the handle 32;

[0062] The locking block 33 has a slot 34 that matches the positioning rod 24. The locking block 33 is a lifting structure at the head of the handle 32. The slot 34 is used to engage the positioning rod 24 to complete the function of the telescopic component 2. Specifically, the slot 34 and the positioning rod 24, the handle 32 and the connecting rod 35, and the connecting rod 35 and the mounting base 31 work together to complete the downward pressing action of the lifting component 3. At the same time, when the locking block 33 hooks the positioning rod 24, the position of the connecting rod 35 is tilted to the right, that is, the upper end of the connecting rod 35 is closer to the telescopic component 2, and the lower end is further away from the telescopic component 2. Figure 2 As shown, the connecting rod 35 provides a supporting force to the handle 2, and together with the action of the locking block 33 and the positioning rod 24, they form a lever structure to complete the action of lifting component 3.

[0063] Furthermore, the embedded component 4 includes a base plate 41 and a U-shaped embedded block 42;

[0064] The base plate 41 is horizontally positioned at the bottom end of the outer rod 21;

[0065] The pre-embedded block 42 is set with its opening facing upwards and is bolted to the base plate 41;

[0066] A counterweight block 5 is installed inside the embedded block 42;

[0067] The pre-embedded component 4 is the bottom center-of-gravity stabilizing structure of the overall support. It is buried underground to ensure that the support will not tilt. The base plate 41 is used to expand the lateral contact area with the ground to further improve the overall stability of the support. The pre-embedded block 42 is bolted to the lower end of the base plate 41, and the counterweight block 5 is placed in the pre-embedded block 42 and buried underground together. This effectively improves the overall stability of the support and also makes it easier to disassemble and replace during later replacement and maintenance.

[0068] When in use: dig a pre-embedded pit at the measured and positioned point on site, and bury the outer rod 21 of the telescopic component 2 into the ground along with the pre-embedded component 4. At this time, it is necessary to ensure that the base plate 41 is buried to a certain depth, that is, a part of the bottom end of the outer rod 21 needs to be buried in the ground together. After the filling is completed and the soil foundation is compacted, put the inner rod 22 into the outer rod 21 until it contacts the limiting plate 211. At this time, insert the positioning rod 24 into the upper positioning hole 23 to further support and position the inner rod 22.

[0069] Afterwards, depending on the site conditions, the upper ends of the center rod 11 and the inner rod 22 of the support frame 1 can be connected by flange or welded together to complete the installation of the overall support frame.

[0070] When lifting, hold the left end of the handle 32 and engage the slot 34 of the locking block 33 with the positioning rod 24. Then press down the tail end of the handle 32, and the locking block 33 will lift up, causing the inner rod 22 to rise. Then insert the other positioning rod 24 into the lower positioning hole 23, and repeat the process to raise the inner rod 22 to the required height, thus completing the overall height increase of the bracket. The simple structure makes the bracket reliable and easy to operate. After one assembly, customers can perform lifting operations or maintenance and replacement themselves, making the maintenance cost of the bracket lower and more convenient.

[0071] Depending on the site conditions, the handle 32 and the connecting rod 35 can be removed together. That is, each bracket only needs to be installed with the mounting base 31. Then, the connecting rod 35 and the mounting base 31 can be hinged together by a double-ended screw, so that the handle 32 can be used repeatedly. The lifting height of the telescopic component 2 can reach 2 meters. Combined with the height of the outer rod 21 and the height of the support frame 1, the overall height of the hail protection net bracket can reach the range of 2-6 meters to meet the needs of different types of crops.

[0072] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
