Description

Technical Field

[0001] This utility model relates to the field of agriculture and horticulture, and more specifically, to an insect-proof and light-transmitting protective cover for agriculture and horticulture. Background Technology

[0002] In the field of agriculture and horticulture, the protection of plant seedlings is crucial for their growth and development, so protective covers are needed to protect them.

[0003] Chinese Patent Publication No. CN220307960U provides a seedling protective cover. The seedling protective cover includes a seedling protective cover body and a lifting protective mechanism. The seedling protective cover body includes a frame and a protective net. The frame is placed on the ground, and its outer wall is attached to the inner wall of the protective net. The lifting protective mechanism includes a protective part and a limiting part. The bottom outer wall of the protective part is attached to the inner wall of the frame, and its top extends out of the top of the frame. The top of the limiting part is welded to the bottom side of the protective part, and its bottom outer wall is slidably connected to the inner wall of the frame.

[0004] However, in the aforementioned patent, since four threaded rods are used for height adjustment, the operator needs to rotate four limit nuts simultaneously to complete the rotation of the threaded rods. This process is rather tedious and slow, and the adjustment speed is inconvenient, thus having certain limitations in use.

[0005] Therefore, an insect-proof and light-transmitting protective cover for agricultural and horticultural use is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide an insect-proof and light-transmitting protective cover for agricultural horticulture, which can realize the function of quickly adjusting the height of the protective cover.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] An agricultural and horticultural insect-proof and light-transmitting protective cover includes a base, a first protective cover fixedly connected to the top of the base, a second protective cover slidably connected inside the first protective cover, the base, the first protective cover, and the second protective cover are all made of transparent plastic, the outer wall of the first protective cover has four sliding grooves arranged in an equidistant circular array, and the second protective cover has four sliding blocks fixedly connected, the four sliding blocks being slidably connected inside the four sliding grooves respectively.

[0011] Furthermore, the outer walls of the four sliding blocks are fixedly connected with connecting rings, which are located outside the second protective cover and the first protective cover, and the connecting rings are slidably connected to the outer wall of the first protective cover.

[0012] Furthermore, the outer wall of the first protective cover is provided with four rows of limiting holes at equal intervals, and each row of limiting holes is composed of a linear equidistant array of six limiting holes.

[0013] Furthermore, four mounting blocks are fixedly connected to the outer wall of the connecting ring. The four mounting blocks are arranged in an equidistant circular array, and springs are fixedly connected inside each of the four mounting blocks.

[0014] Furthermore, one end of each of the four springs is fixedly connected to a limiting block, and the four limiting blocks slide inside the mounting block.

[0015] Furthermore, all four limiting blocks are engaged with the limiting holes.

[0016] Furthermore, four ground nails are fixedly connected to the bottom of the base, and the four ground nails are arranged in an equidistant circular array below the base.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] In this solution, the operator pulls the connecting ring to vertically raise and lower the No. 2 protective cover. The inner wall of the limiting hole presses against the limiting block, causing it to slide into the mounting block. The spring contracts, and when the No. 2 protective cover reaches the target height, the force is stopped, and the spring rebounds, locking the limiting block into the limiting hole. The wedge-shaped fit creates a self-locking mechanism, forming a four-point rigid constraint to prevent displacement. The adjustment is completed in three steps: "lifting, positioning, and releasing." This method can protect seedlings of different heights while significantly improving adjustment efficiency compared to traditional knob or bolt structures. Attached Figure Description

[0029] Example 1

[0030] Please see Figure 1-4 An agricultural and horticultural insect-proof and light-transmitting protective cover includes a base 1. A first protective cover 11 is fixedly connected to the top of the base 1. A second protective cover 12 is slidably connected inside the first protective cover 11. The base 1, the first protective cover 11, and the second protective cover 12 are all made of transparent plastic. The outer wall of the first protective cover 11 has four sliding grooves 13 arranged in an equidistant circular array. The second protective cover 12 is fixedly connected to four sliding blocks 15, which are slidably connected inside the four sliding grooves 13. The outer wall of the four sliding blocks 15 is fixedly connected to a connecting ring 16, which is located outside the second protective cover 12 and the first protective cover 11. The connecting ring 16 is slidably connected to the outer wall of the first protective cover 11.

[0031] In this embodiment, the four sliding blocks 15 slide inside the four sliding grooves 13 respectively, which can position the first protective cover 11 and the second protective cover 12. The four sliding blocks 15 and the sliding grooves 13 are circumferentially symmetrically distributed to form a stable four-point constraint structure, so that when the second protective cover 12 and the first protective cover 11 slide relative to each other, the second protective cover 12 will not rotate, ensuring the stability of vertical lifting. The operator can pull the connecting ring 16 to make the second protective cover 12 slide precisely along the axial direction of the first protective cover 11. During the sliding process, the sealing rubber ring on the inner wall of the connecting ring 16 is tightly attached to the outer wall of the first protective cover 11, which can not only prevent dust and insects, but also provide a moderate damping feel.

[0032] Example 2

[0033] Please see Figure 1-4 An agricultural and horticultural insect-proof and light-transmitting protective cover is provided. The outer wall of the first protective cover 11 is provided with four rows of limiting holes 14 at equal intervals. Each row of limiting holes 14 is composed of six limiting holes 14 arranged in a linear equidistant array. The outer wall of the connecting ring 16 is fixedly connected to four mounting blocks 17. The four mounting blocks 17 are arranged in an equidistant circular array. Springs 18 are fixedly connected inside each of the four mounting blocks 17. One end of each of the four springs 18 is fixedly connected to a limiting block 19. The four limiting blocks 19 slide inside the mounting blocks 17 and engage with the limiting holes 14. Four ground nails 2 are fixedly connected below the base 1. The four ground nails 2 are arranged in an equidistant circular array below the base 1.

[0034] In this embodiment, when the worker pulls the connecting ring 16 to move the second protective cover 12 vertically, the inner wall of the limiting hole 14 will press against the limiting block 19. After being pressed by the inner wall of the limiting hole 14, the limiting block 19 will slide towards the inside of the mounting block 17. During this process, the spring 18 will be compressed by the limiting block 19 and undergo elastic deformation and contraction. As the second protective cover 12 continues to move, when the second protective cover 12 reaches the target height, the worker stops applying force, and the spring 18 immediately releases its elastic potential energy, driving the limiting block 19 precisely. The limiting hole 14 is inserted into the corresponding position. The wedge-shaped mating surface design of the limiting block 19 and the limiting hole 14 creates a self-locking effect at the moment of engagement, forming a four-point rigid constraint evenly distributed in the circumference. This effectively prevents the second protective cover 12 from being displaced by external force. This structure can be adjusted without additional tools, and the operation process is simplified to three steps: "lift-position-release". The adjustment efficiency is significantly improved compared to the traditional knob or bolt structure. Compared to bolt-type height adjustment, the operator only needs to pull the connecting ring 16 upwards, which is convenient and quick, improving the operator's work efficiency.

[0035] Working principle: Workers can place the seedlings inside protective covers 11 and 12. Ground nails 2 are inserted into the soil to enhance stability. Four sliding blocks 15 slide within four sliding grooves 13, simultaneously positioning protective covers 11 and 12. The four sliding blocks 15 and sliding grooves 13 are symmetrically distributed, forming a stable four-point constraint structure. This ensures that protective cover 12 will not rotate when it slides relative to protective cover 11, guaranteeing vertical lifting stability. Workers can precisely slide protective cover 12 along the axial direction of protective cover 11 by pulling the connecting ring 16. During sliding, the sealing rubber ring on the inner wall of the connecting ring 16 tightly adheres to the outer wall of protective cover 11, providing dust and insect protection as well as moderate damping. When the worker pulls the connecting ring 16, it moves protective cover 12... During vertical lifting, the inner wall of the limiting hole 14 will press against the limiting block 19. After being pressed by the inner wall of the limiting hole 14, the limiting block 19 will slide towards the inside of the mounting block 17. During this process, the spring 18 will be compressed by the limiting block 19 and undergo elastic deformation and contraction. As the second protective cover 12 moves continuously, when the second protective cover 12 reaches the target height, the staff stops applying force, and the spring 18 immediately releases its elastic potential energy, driving the limiting block 19 to accurately engage with the corresponding limiting hole 14. The wedge-shaped mating surface design of the limiting block 19 and the limiting hole 14 creates a self-locking effect at the moment of engagement, forming a four-point rigid constraint evenly distributed in the circumference, effectively preventing the second protective cover 12 from displacing due to external force. This structure can be adjusted without additional tools, and the operation process is simplified to three steps: "lift-position-release". The adjustment efficiency is significantly improved compared with the traditional knob or bolt structure, thereby achieving the purpose of protecting the support seedlings at different heights.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
