Description

Technical Field

[0001] This utility model relates to the field of insect-attracting lamp technology, and in particular to an agricultural insect-attracting lamp. Background Technology

[0002] In agricultural production, agricultural insect-attracting lamps, as green pest control devices, are widely used in fields, greenhouses, orchards, and other field settings. They attract and kill agricultural pests using specific wavelength LED light sources, reducing the use of chemical pesticides and ensuring crop safety. These insect-attracting lamps need to operate in outdoor field environments for extended periods. Field environments are characterized by high humidity, dust, frequent rain and dew, and large diurnal temperature variations, placing stringent requirements on the protective performance of the lamp's key components.

[0003] Most traditional insect-attracting lamps have exposed screw heads without dedicated protective components; some are equipped with simple plastic covers, but the protective effect is poor. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural insect-attracting lamp to solve the problems of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural insect-attracting lamp, comprising an agricultural insect-attracting main lamp, wherein a lamp holder connecting screw head is coaxially provided at the top of the agricultural insect-attracting main lamp, the lamp holder connecting screw head being used to engage with an external lamp holder thread, so that the agricultural insect-attracting main lamp can achieve electrical connection and illuminate and attract insects through the lamp holder connecting screw head;

[0006] The outer circumferential surface of the lamp holder connecting screw head is fitted with a protective component. This protective component can slide along the axial direction of the lamp holder connecting screw head. By sliding the protective component, it can cover the outer circumferential surface of the lamp holder connecting screw head and the connection between the lamp holder connecting screw head and the lamp holder, so as to form a shielding and protection for the lamp holder connecting screw head.

[0007] Preferably, the protective component includes a screw-in support sleeve, which is coaxially sleeved on the outer peripheral surface of the lamp holder connecting screw head, and the bottom end of the screw-in support sleeve is fixedly connected to the top outer peripheral surface of the agricultural insect-attracting main lamp.

[0008] The inner wall of the free end of the screw support sleeve away from the main agricultural insect-attracting lamp has an annular groove. The inner wall of the annular groove is slidably connected to a screw-hole blocking sleeve along its axial direction. By pushing the screw-hole blocking sleeve to slide along the annular groove axially, the screw-hole blocking sleeve can partially or completely cover the installation part of the lamp holder connecting screw head, thereby achieving shielding, protection and sealing of the lamp holder connecting screw head.

[0009] Preferably, a push block sliding groove is provided on the side wall of the screw support sleeve, extending along its axial direction. One end of the push block sliding groove is connected to the annular groove of the screw support sleeve, and the other end extends to the end of the screw support sleeve near the main agricultural insect-attracting lamp.

[0010] The inner wall of the push block sliding groove is slidably connected to a sliding sleeve push block. One end of the sliding sleeve push block is fixedly connected to the outer circumferential surface of the threaded obstruction sliding sleeve, and the other end extends out of the push block sliding groove. The sliding sleeve push block and the inner wall of the push block sliding groove are interference-fitted to achieve position positioning during the sliding process of the threaded obstruction sliding sleeve.

[0011] Preferably, the end of the screw-hole blocking sleeve away from the main agricultural insect-attracting lamp is coaxially fixedly connected to a screw-hole connecting sleeve; the inner diameter of the screw-hole connecting sleeve is adapted to the outer circumferential contour of the lamp holder connecting screw head, and as the screw-hole blocking sleeve slides along the axial direction of the screw-hole support sleeve, the screw-hole connecting sleeve can be simultaneously covered to the connection point between the lamp holder connecting screw head and the lamp holder, or detached from the connection point.

[0012] Preferably, a threaded sealing ring is coaxially fixedly connected to the inner wall of the threaded connection sleeve at the end away from the threaded shielding sleeve; when the threaded connection sleeve covers the connection between the lamp holder connecting screw head and the lamp holder, the threaded sealing ring is interference-fitted onto the outer peripheral surface of the connection between the lamp holder connecting screw head and the lamp holder to enhance the sealing and protection effect at the connection.

[0013] Preferably, an anti-slip ring is coaxially sleeved and fixedly connected to the outer circumferential surface of the threaded connection sleeve; the anti-slip ring is arranged along the circumferential direction of the threaded connection sleeve to increase the friction when holding the threaded connection sleeve, making it easier to push the threaded blocking sleeve to slide.

[0014] Preferably, an anti-scalding component is coaxially sleeved on the outer surface of the agricultural insect-attracting main lamp, near the side of the screw-connected protective sleeve; the anti-scalding component includes an anti-scalding outer ring and a heat-insulating ring, the heat-insulating ring is located between the anti-scalding outer ring and the agricultural insect-attracting main lamp, and the inner wall of the anti-scalding outer ring is fixedly connected to the outer peripheral surface of the heat-insulating ring, and the inner wall of the heat-insulating ring is fixedly connected to the outer surface of the agricultural insect-attracting main lamp;

[0015] The heat insulation ring is made of heat insulation cotton to isolate the heat generated by the main agricultural insect-attracting lamp during operation and prevent burns when holding it.

[0016] Preferably, the outer circumferential surface of the heat-resistant outer ring is provided with a plurality of ring anti-slip grooves evenly distributed along its circumferential direction; each ring anti-slip groove extends along the axial direction of the heat-resistant outer ring to increase the friction when holding the heat-resistant outer ring, making it easier to load and unload the agricultural insect-attracting main lamp.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this utility model, the protective component, through the physical shielding of the screw-connected protective sleeve 4 and the elastic sealing of the screw-connected sealing ring 7, continuously blocks the infiltration of rainwater and dew in the field and the accumulation of dust, thus preventing poor circuit contact or short circuit at the lamp holder connection point.

Detailed Implementation

[0025] Example 1, as Figure 1-3 As shown, an agricultural insect-attracting lamp has an agricultural insect-attracting main lamp 1 as its core supporting component. The lamp body is injection molded from high-temperature resistant ABS plastic, possessing good impact resistance and weather resistance, suitable for hanging or fixed installation in agricultural fields. The lamp body integrates an LED insect-attracting light source assembly (including a substrate, LED beads, and driving circuit, not shown in the figure). The LED beads use a specific wavelength spectrum to specifically attract common agricultural pests, enhancing the insect-attracting effect.

[0026] At the top of the main agricultural insect-attracting lamp 1, a lamp holder connecting screw head 8 is coaxially fixed along the lamp body axis. The screw head is made of nickel-plated brass, which ensures good conductivity to achieve power transmission and has excellent rust resistance to resist corrosion in the humid field environment. Its thread specification matches that of conventional agricultural insect-attracting lamp holders, and is used to realize the electrical connection and mechanical fixation between the main agricultural insect-attracting lamp 1 and the external lamp holder. Then, the lamp holder obtains power to light up the LED light source and complete the insect-attracting operation.

[0027] A protective component for moisture and dust protection is fitted around the outer periphery of the lamp holder connecting screw head 8, providing dynamic shielding and sealing protection for the lamp holder connection area. On the outer surface of the main agricultural insect-attracting lamp 1, near the protective component, a heat-insulating and anti-scalding component is coaxially fitted, providing a safe grip for users when installing or removing the insect-attracting lamp. These two components, together with the main agricultural insect-attracting lamp 1, form a modular assembly structure, each independently fulfilling its function while working together to ensure the overall performance of the insect-attracting lamp, balancing protective effectiveness and ease of operation.

[0028] The threaded support sleeve 2 is the basic support component of the protective structure. Made of transparent PC plastic, its transparency allows users to easily observe the installation status of the lamp holder connecting screw head 8 without disassembling the protective structure. Its inner diameter is slightly larger than the outer diameter of the lamp holder connecting screw head 8 to ensure no interference with the screw head during installation. Its length is designed not to obstruct the exposed threaded portion of the lamp holder connecting screw head 8, avoiding any impact on the mating installation of the screw head and the lamp holder. During assembly, the threaded support sleeve 2 is coaxially fitted onto the outer circumference of the lamp holder connecting screw head 8, and the bottom end of the threaded support sleeve 2 is fixedly connected to the top outer circumference of the agricultural insect-attracting main lamp 1 using ultrasonic welding or high-strength weather-resistant adhesive. During the fixing process, it is essential to ensure that the threaded support sleeve 2, the lamp body, and the lamp holder connecting screw head 8 are coaxial and without radial offset to guarantee smooth operation of subsequent sliding components. On the inner wall of the free end of the screw-in support sleeve 2 away from the main agricultural insect-attracting lamp 1, there is an annular groove extending along its circumference. This annular groove provides a sliding track for the screw-in blocking sleeve 3. Its structure is adapted to the shape of the screw-in blocking sleeve 3 to ensure that the sliding process is stable and without jamming.

[0029] The threaded end shielding sleeve 3 is made of the same transparent PC plastic as the threaded end support sleeve 2, ensuring visual consistency and ease of observation for the overall protective components. Its outer diameter matches the inner diameter of the annular groove of the threaded end support sleeve 2, and the sliding clearance is controlled within a reasonable range, ensuring smooth axial reciprocating sliding along the annular groove while preventing excessive clearance that could lead to dust infiltration. Its inner wall is polished smooth without burrs to prevent scratching damage to the surface of the lamp holder connecting screw head 8 during sliding. During assembly, the threaded end shielding sleeve 3 is slid into the annular groove along the axial direction of the threaded end support sleeve 2. Its sliding stroke is designed to completely cover the installation part of the lamp holder connecting screw head 8. When the sleeve slides to the top, it can cover the connection between the screw head and the lamp holder; when it slides to the bottom, it can completely expose the screw thread without affecting the installation operation.

[0030] To achieve sliding control and positioning of the screw-in blocking sleeve 3, a push block sliding groove 5 is provided axially on the side wall of the screw-in support sleeve 2. One end of the push block sliding groove 5 connects to the annular groove of the screw-in support sleeve 2, and the other end extends to the end of the screw-in support sleeve 2 near the main agricultural insect-attracting lamp 1. The length of the groove matches the sliding stroke of the screw-in blocking sleeve 3, providing a moving path for the sleeve push block 9. The sleeve push block 9 adopts a composite structure of rubber-coated rigid PVC. The outer rubber material increases the friction when pushed by the finger, preventing slippage; the inner rigid PVC material ensures structural strength and prevents deformation and damage during pushing. Its cross-section is "T"-shaped. The transverse end is embedded in a pre-set groove on the outer circumference of the screw-in blocking sleeve 3 and fixed with glue to ensure synchronous movement with the sleeve; the longitudinal end extends out of the push block sliding groove 5, with the extension length suitable for easy finger hooking and pushing, improving operational convenience.

[0031] Meanwhile, the longitudinal end of the sliding sleeve pusher block 9 and the inner wall of the pusher block sliding groove 5 are interference-fitted. The interference is designed so that it does not hinder manual pushing of the sliding sleeve, but can also achieve the position positioning of the screw-hole blocking sliding sleeve 3 through the friction between the two after sliding stops, preventing it from sliding due to its own weight or field wind, vibration, etc., and ensuring stable protection. The screw-hole connecting sleeve 4 is made of opaque ABS plastic. Its opacity can prevent external light from interfering with the insect-attracting light source effect of the agricultural insect-attracting main lamp 1 after being reflected by the protective component. Its inner diameter is adapted to the outer circumference of the connection part between the lamp holder connecting screw head 8 and the lamp holder, ensuring that it can tightly cover the part. One end of the screw-hole connecting sleeve 4 and the end of the screw-hole blocking sliding sleeve 3 away from the agricultural insect-attracting main lamp 1 are coaxially fixedly connected by ultrasonic welding. The welding process can ensure that the connection between the two is firm and prevent them from falling off after long-term use. At the same time, it can move synchronously with the sliding of the screw-hole blocking sliding sleeve 3.

[0032] On the inner wall of the threaded connection sleeve 4 at the end away from the threaded shielding sleeve 3, a threaded sealing ring 7 is coaxially fixed. This sealing ring is made of aging-resistant silicone rubber, possessing good elasticity and weather resistance. It can maintain its elasticity for a long time in the environment of large temperature differences between day and night and high humidity in agricultural fields, and is not prone to hardening or cracking. When the threaded connection sleeve 4 is placed over the lamp holder connection part, the threaded sealing ring 7 can tightly fit the outer circumference of the connection part, forming a ring-shaped sealing structure, effectively preventing rainwater, dew, and dust from entering the connection and avoiding circuit failure. In addition, on the outer circumference of the threaded connection sleeve 4, a sleeve anti-slip ring 6 is coaxially fitted and fixed with glue. This anti-slip ring is made of nitrile rubber, possessing excellent wear resistance and anti-slip properties, and its surface is pressed with diamond-shaped anti-slip patterns to further increase friction. When it is inconvenient to operate the sliding sleeve pusher block 9 (such as when hands are wet or when working with gloves), the user can directly hold the protective sleeve anti-slip ring 6 to drive the threaded connection protective sleeve 4 and the threaded blocking sliding sleeve 3 to slide, improving the flexibility of operation and adapting to different field operation scenarios.

[0033] The anti-scalding components include an outer anti-scalding ring 10 and a heat-insulating ring 12, both of which are ring-shaped and coaxially fitted onto the outer surface of the agricultural insect-attracting lamp 1, forming a composite structure of "inner heat insulation + outer grip," balancing heat insulation effect and ease of operation. The heat-insulating ring 12 is made of high-density insulation cotton, which has excellent heat-blocking properties, effectively preventing the heat from the agricultural insect-attracting lamp 1 during operation from being transferred to the lamp surface. Its inner diameter matches the outer diameter of the agricultural insect-attracting lamp 1, and its inner wall is fixedly connected to the outer surface of the agricultural insect-attracting lamp 1 with high-temperature resistant adhesive. After fixing, there is no loosening or displacement, ensuring uniform heat insulation and avoiding the risk of burns due to localized heat accumulation.

[0034] The anti-scalding outer ring 10 is made of PP plastic, which is lightweight, impact-resistant, and chemically resistant. It protects the internal heat-insulating ring 12 from damage caused by external impacts in the field, while providing a stable grip for the user. Its inner diameter matches the outer diameter of the heat-insulating ring 12, and a snap-fit ​​structure secures it to the heat-insulating ring 12. Specifically, the inner wall of the anti-scalding outer ring 10 is provided with several elastic snaps, and corresponding slots are provided on the outer circumference of the heat-insulating ring 12. During assembly, the snaps are simply inserted into the slots to complete the fixation. Disassembly is convenient and facilitates subsequent maintenance and replacement. To further improve grip stability, especially in humid field environments, several anti-slip grooves 13 are evenly provided along the circumference of the outer circumference of the anti-scalding outer ring 10. Each groove extends axially along the anti-scalding outer ring 10, and the spacing between the grooves is equal. The groove structure increases the contact friction between the fingers and the ring surface, preventing slippage when hands are sweaty or damp from the field, ensuring a firm grip when the user loads and unloads the agricultural insect-attracting lamp 1, and reducing the risk of the lamp slipping and getting damaged.

[0035] Working principle

[0036] The user hooks their finger onto the sliding sleeve push block 9 and slides it along the sliding groove 5 towards the main agricultural insect-attracting lamp 1. Simultaneously, the screw-end blocking sleeve 3 moves down along the annular groove of the screw-end support sleeve 2 until the screw-end connecting sleeve 4 is completely detached from the top of the lamp holder connecting screw head 8, fully exposing the threaded part of the lamp holder connecting screw head 8 for easy mating with the external lamp holder. The user holds the heat-resistant outer ring sleeve 10, using the anti-slip groove 13 on the outer circumference of the ring sleeve to increase grip friction and ensure stable holding. Then, the user aligns the lamp holder connecting screw head 8 with the screw hole of the external lamp holder and rotates the main agricultural insect-attracting lamp 1 clockwise until the lamp holder connecting screw head 8 is fully screwed into the lamp holder. The process involves electrically connecting the main agricultural insect-attracting lamp 1 to the lamp holder (ensuring the LED light source can be powered normally) and mechanically fixing it (ensuring the lamp body is securely installed). After installation, the user pushes the sliding sleeve push block 9 upwards, causing the screw-hole blocking sliding sleeve 3 and the screw-hole connecting sleeve 4 to move upwards synchronously along the screw-hole support sleeve 2 until the screw-hole connecting sleeve 4 completely covers the connection between the lamp holder connecting screw head 8 and the lamp holder. At this time, the screw-hole sealing ring 7, due to its elastic deformation, is pressed against the outer circumference of the connection part, forming a tight seal. At the same time, the screw-hole blocking sliding sleeve 3 covers the exposed part of the lamp holder connecting screw head 8 that is not covered by the lamp holder, completing the moisture-proof and dust-proof protection of the connection part. The installation process is then complete.

[0037] During operation, the agricultural insect-attracting lamp 1 uses the physical shielding of the screw-connected sleeve 4 and the elastic sealing of the screw-connected sealing ring 7 to continuously block rainwater, dew, and dust from seeping in and accumulating, thus preventing poor circuit contact or short circuits at the lamp holder connection. The anti-scalding component uses the heat-insulating ring 12 to limit the heat generated by the lamp body to the inside of the lamp body, keeping the surface temperature of the anti-scalding outer ring 10 within a safe range for human contact. Even if the lamp body operates for a long time, users will not be burned when touching the ring.

[0038] Since both the screw support sleeve 2 and the screw shielding sleeve 3 are made of transparent material, users can directly observe the inside of both to intuitively judge the installation status of the lamp holder connecting screw head 8 (such as whether it is loose or whether foreign objects have entered), without having to disassemble the protective components, thus reducing the complexity of maintenance operations.

[0039] When it is necessary to disassemble the agricultural insect-attracting lamp (such as replacing the lamp body, maintaining the circuit, or relocating the installation position), the operation steps are as follows: First, the user pushes the sliding sleeve push block 9 downwards towards the main agricultural insect-attracting lamp 1, causing the screw-connecting sleeve 4 to disengage from the lamp holder connection part, exposing the lamp holder connecting screw head 8 again; then, holding the heat-resistant outer ring 10, the user rotates the main agricultural insect-attracting lamp 1 counterclockwise to unscrew the lamp holder connecting screw head 8 from the lamp holder, completing the disassembly. The entire disassembly process does not require any tools, making it convenient to operate and suitable for agricultural field operation scenarios without auxiliary tools. The main agricultural insect-attracting lamp 1 is the core load-bearing component, and its lamp body is made of high-temperature resistant ABS plastic injection molding, which has good impact resistance and weather resistance, suitable for hanging or fixed installation scenarios in agricultural fields. The lamp body integrates an LED insect-attracting light source component (including a substrate, LED beads and driving circuit, not shown in the figure), where the LED beads use a specific wavelength spectrum to specifically attract common agricultural pests, improving the insect-attracting effect.

[0040] At the top of the main agricultural insect-attracting lamp 1, a lamp holder connecting screw head 8 is coaxially fixed along the lamp body axis. The screw head is made of nickel-plated brass, which ensures good conductivity to achieve power transmission and has excellent rust resistance to resist corrosion in the humid field environment. Its thread specification matches that of conventional agricultural insect-attracting lamp holders, and is used to realize the electrical connection and mechanical fixation between the main agricultural insect-attracting lamp 1 and the external lamp holder. Then, the lamp holder obtains power to light up the LED light source and complete the insect-attracting operation.

[0041] A protective component for moisture and dust protection is fitted around the outer periphery of the lamp holder connecting screw head 8, providing dynamic shielding and sealing protection for the lamp holder connection area. On the outer surface of the main agricultural insect-attracting lamp 1, near the protective component, a heat-insulating and anti-scalding component is coaxially fitted, providing a safe grip for users when installing or removing the insect-attracting lamp. These two components, together with the main agricultural insect-attracting lamp 1, form a modular assembly structure, each independently fulfilling its function while working together to ensure the overall performance of the insect-attracting lamp, balancing protective effectiveness and ease of operation.

[0042] The threaded support sleeve 2 is the basic support component of the protective structure. Made of transparent PC plastic, its transparency allows users to easily observe the installation status of the lamp holder connecting screw head 8 without disassembling the protective structure. Its inner diameter is slightly larger than the outer diameter of the lamp holder connecting screw head 8 to ensure no interference with the screw head during installation. Its length is designed not to obstruct the exposed threaded portion of the lamp holder connecting screw head 8, avoiding any impact on the mating installation of the screw head and the lamp holder. During assembly, the threaded support sleeve 2 is coaxially fitted onto the outer circumference of the lamp holder connecting screw head 8, and the bottom end of the threaded support sleeve 2 is fixedly connected to the top outer circumference of the agricultural insect-attracting main lamp 1 using ultrasonic welding or high-strength weather-resistant adhesive. During the fixing process, it is essential to ensure that the threaded support sleeve 2, the lamp body, and the lamp holder connecting screw head 8 are coaxial and without radial offset to guarantee smooth operation of subsequent sliding components. On the inner wall of the free end of the screw-in support sleeve 2 away from the main agricultural insect-attracting lamp 1, there is an annular groove extending along its circumference. This annular groove provides a sliding track for the screw-in blocking sleeve 3. Its structure is adapted to the shape of the screw-in blocking sleeve 3 to ensure that the sliding process is stable and without jamming.

[0043] The threaded end shielding sleeve 3 is made of the same transparent PC plastic as the threaded end support sleeve 2, ensuring visual consistency and ease of observation for the overall protective components. Its outer diameter matches the inner diameter of the annular groove of the threaded end support sleeve 2, and the sliding clearance is controlled within a reasonable range, ensuring smooth axial reciprocating sliding along the annular groove while preventing excessive clearance that could lead to dust infiltration. Its inner wall is polished smooth without burrs to prevent scratching damage to the surface of the lamp holder connecting screw head 8 during sliding. During assembly, the threaded end shielding sleeve 3 is slid into the annular groove along the axial direction of the threaded end support sleeve 2. Its sliding stroke is designed to completely cover the installation part of the lamp holder connecting screw head 8. When the sleeve slides to the top, it can cover the connection between the screw head and the lamp holder; when it slides to the bottom, it can completely expose the screw thread without affecting the installation operation.

[0044] To achieve sliding control and positioning of the screw-in blocking sleeve 3, a push block sliding groove 5 is provided axially on the side wall of the screw-in support sleeve 2. One end of the push block sliding groove 5 connects to the annular groove of the screw-in support sleeve 2, and the other end extends to the end of the screw-in support sleeve 2 near the main agricultural insect-attracting lamp 1. The length of the groove matches the sliding stroke of the screw-in blocking sleeve 3, providing a moving path for the sleeve push block 9. The sleeve push block 9 adopts a composite structure of rubber-coated rigid PVC. The outer rubber material increases the friction when pushed by the finger, preventing slippage; the inner rigid PVC material ensures structural strength and prevents deformation and damage during pushing. Its cross-section is "T"-shaped. The transverse end is embedded in a pre-set groove on the outer circumference of the screw-in blocking sleeve 3 and fixed with glue to ensure synchronous movement with the sleeve; the longitudinal end extends out of the push block sliding groove 5, with the extension length suitable for easy finger hooking and pushing, improving operational convenience.

[0045] Meanwhile, the longitudinal end of the sliding sleeve pusher block 9 and the inner wall of the pusher block sliding groove 5 are interference-fitted. The interference is designed so that it does not hinder manual pushing of the sliding sleeve, but can also achieve the position positioning of the screw-hole blocking sliding sleeve 3 through the friction between the two after sliding stops, preventing it from sliding due to its own weight or field wind, vibration, etc., and ensuring stable protection. The screw-hole connecting sleeve 4 is made of opaque ABS plastic. Its opacity can prevent external light from interfering with the insect-attracting light source effect of the agricultural insect-attracting main lamp 1 after being reflected by the protective component. Its inner diameter is adapted to the outer circumference of the connection part between the lamp holder connecting screw head 8 and the lamp holder, ensuring that it can tightly cover the part. One end of the screw-hole connecting sleeve 4 and the end of the screw-hole blocking sliding sleeve 3 away from the agricultural insect-attracting main lamp 1 are coaxially fixedly connected by ultrasonic welding. The welding process can ensure that the connection between the two is firm and prevent them from falling off after long-term use. At the same time, it can move synchronously with the sliding of the screw-hole blocking sliding sleeve 3.

[0046] On the inner wall of the threaded connection sleeve 4 at the end away from the threaded shielding sleeve 3, a threaded sealing ring 7 is coaxially fixed. This sealing ring is made of aging-resistant silicone rubber, possessing good elasticity and weather resistance. It can maintain its elasticity for a long time in the environment of large temperature differences between day and night and high humidity in agricultural fields, and is not prone to hardening or cracking. When the threaded connection sleeve 4 is placed over the lamp holder connection part, the threaded sealing ring 7 can tightly fit the outer circumference of the connection part, forming a ring-shaped sealing structure, effectively preventing rainwater, dew, and dust from entering the connection and avoiding circuit failure. In addition, on the outer circumference of the threaded connection sleeve 4, a sleeve anti-slip ring 6 is coaxially fitted and fixed with glue. This anti-slip ring is made of nitrile rubber, possessing excellent wear resistance and anti-slip properties, and its surface is pressed with diamond-shaped anti-slip patterns to further increase friction. When it is inconvenient to operate the sliding sleeve pusher block 9 (such as when hands are wet or when working with gloves), the user can directly hold the protective sleeve anti-slip ring 6 to drive the threaded connection protective sleeve 4 and the threaded blocking sliding sleeve 3 to slide, improving the flexibility of operation and adapting to different field operation scenarios.

[0047] The anti-scalding components include an outer anti-scalding ring 10 and a heat-insulating ring 12, both of which are ring-shaped and coaxially fitted onto the outer surface of the agricultural insect-attracting lamp 1, forming a composite structure of "inner heat insulation + outer grip," balancing heat insulation effect and ease of operation. The heat-insulating ring 12 is made of high-density insulation cotton, which has excellent heat-blocking properties, effectively preventing the heat from the agricultural insect-attracting lamp 1 during operation from being transferred to the lamp surface. Its inner diameter matches the outer diameter of the agricultural insect-attracting lamp 1, and its inner wall is fixedly connected to the outer surface of the agricultural insect-attracting lamp 1 with high-temperature resistant adhesive. After fixing, there is no loosening or displacement, ensuring uniform heat insulation and avoiding the risk of burns due to localized heat accumulation.

[0048] The anti-scalding outer ring 10 is made of PP plastic, which is lightweight, impact-resistant, and chemically resistant. It protects the internal heat-insulating ring 12 from damage caused by external impacts in the field, while providing a stable grip for the user. Its inner diameter matches the outer diameter of the heat-insulating ring 12, and a snap-fit ​​structure secures it to the heat-insulating ring 12. Specifically, the inner wall of the anti-scalding outer ring 10 is provided with several elastic snaps, and corresponding slots are provided on the outer circumference of the heat-insulating ring 12. During assembly, the snaps are simply inserted into the slots to complete the fixation. Disassembly is convenient and facilitates subsequent maintenance and replacement. To further improve grip stability, especially in humid field environments, several anti-slip grooves 13 are evenly provided along the circumference of the outer circumference of the anti-scalding outer ring 10. Each groove extends axially along the anti-scalding outer ring 10, and the spacing between the grooves is equal. The groove structure increases the contact friction between the fingers and the ring surface, preventing slippage when hands are sweaty or damp from the field, ensuring a firm grip when the user loads and unloads the agricultural insect-attracting lamp 1, and reducing the risk of the lamp slipping and getting damaged.

[0049] Working principle

[0050] The user hooks their finger onto the sliding sleeve push block 9 and slides it along the sliding groove 5 towards the main agricultural insect-attracting lamp 1. Simultaneously, the screw-end blocking sleeve 3 moves down along the annular groove of the screw-end support sleeve 2 until the screw-end connecting sleeve 4 is completely detached from the top of the lamp holder connecting screw head 8, fully exposing the threaded part of the lamp holder connecting screw head 8 for easy mating with the external lamp holder. The user holds the heat-resistant outer ring sleeve 10, using the anti-slip groove 13 on the outer circumference of the ring sleeve to increase grip friction and ensure stable holding. Then, the user aligns the lamp holder connecting screw head 8 with the screw hole of the external lamp holder and rotates the main agricultural insect-attracting lamp 1 clockwise until the lamp holder connecting screw head 8 is fully screwed into the lamp holder. The process involves electrically connecting the main agricultural insect-attracting lamp 1 to the lamp holder (ensuring the LED light source can be powered normally) and mechanically fixing it (ensuring the lamp body is securely installed). After installation, the user pushes the sliding sleeve push block 9 upwards, causing the screw-hole blocking sliding sleeve 3 and the screw-hole connecting sleeve 4 to move upwards synchronously along the screw-hole support sleeve 2 until the screw-hole connecting sleeve 4 completely covers the connection between the lamp holder connecting screw head 8 and the lamp holder. At this time, the screw-hole sealing ring 7, due to its elastic deformation, is pressed against the outer circumference of the connection part, forming a tight seal. At the same time, the screw-hole blocking sliding sleeve 3 covers the exposed part of the lamp holder connecting screw head 8 that is not covered by the lamp holder, completing the moisture-proof and dust-proof protection of the connection part. The installation process is then complete.

[0051] During operation, the agricultural insect-attracting lamp 1 uses the physical shielding of the screw-connected sleeve 4 and the elastic sealing of the screw-connected sealing ring 7 to continuously block rainwater, dew, and dust from seeping in and accumulating, thus preventing poor circuit contact or short circuits at the lamp holder connection. The anti-scalding component uses the heat-insulating ring 12 to limit the heat generated by the lamp body to the inside of the lamp body, keeping the surface temperature of the anti-scalding outer ring 10 within a safe range for human contact. Even if the lamp body operates for a long time, users will not be burned when touching the ring.

[0052] Since both the screw support sleeve 2 and the screw shielding sleeve 3 are made of transparent material, users can directly observe the inside of both to intuitively judge the installation status of the lamp holder connecting screw head 8 (such as whether it is loose or whether foreign objects have entered), without having to disassemble the protective components, thus reducing the complexity of maintenance operations.

[0053] When it is necessary to disassemble the agricultural insect-attracting lamp (such as to replace the lamp body, maintain the circuit, or relocate the installation position), the operating steps are as follows: First, the user pushes the sliding sleeve push block 9 downwards towards the main agricultural insect-attracting lamp 1, causing the screw-connecting sleeve 4 to disengage from the lamp holder connection part, exposing the lamp holder connecting screw head 8 again; then, holding the heat-resistant outer ring 10, the user rotates the main agricultural insect-attracting lamp 1 counterclockwise to unscrew the lamp holder connecting screw head 8 from the lamp holder, completing the disassembly. The entire disassembly process requires no tools, is convenient to operate, and is suitable for agricultural field operations without auxiliary tools.

[0054] Each component is assembled in a modular fashion, which facilitates manufacturing and subsequent maintenance and replacement; the transparent protective component design enables visual monitoring of the connection status, reducing unnecessary disassembly operations; the overall structure is compatible with conventional agricultural insect-attracting lamp holders, and can be installed and used without additional lamp holder modifications, reducing the cost of promotion and application.
