Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural insect control equipment, specifically relating to a modular insect control net that can be spliced ​​together. Background Technology

[0002] In the fields of agricultural planting, home ventilation, and industrial ventilation protection, insect nets are the core components for blocking pests from invading and ensuring air circulation. The detachable and firm splicing structure, as well as the angle adjustment and locking functions after splicing, directly affect the adaptability and protective stability. Currently, traditional insect nets have significant defects in terms of limiting fixation and splicing angle adjustment and locking, making it difficult to meet the needs of flexible use in multiple scenarios.

[0003] On the one hand, the existing methods of fixing insect nets to splicing blocks and frames cannot simultaneously ensure both detachability and sturdiness. The common buckle-type fixing is prone to loosening due to material aging and environmental vibration after long-term use, causing the insect net to shift and gaps to appear at the edges, thus failing to effectively block small pests. On the other hand, the splicing block connection structure of existing splicing insect nets lacks angle adjustment and reliable locking capabilities. Traditional splicing structures are mostly straight-line fixed splicing, which can only achieve the longitudinal or lateral extension of the insect net and cannot adapt to non-linear installation scenarios such as corners and tilts. Even if a few splicing structures support angle adjustment, they do not have an effective locking mechanism. The adjusted angle is prone to shift due to wind or external force, and cannot maintain the preset angle for a long time. This not only affects the protective sealing of the insect net, but also reduces the overall aesthetics after installation.

[0004] Therefore, developing a spliced ​​insect net with an integrated detachable and robust limiting structure and angle adjustment and locking functions is the key to solving the problem of adaptability in multiple scenarios, and is of great significance to improving the fixing reliability, angle adaptability and usage flexibility of the insect net. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a splicable and modular insect-proof net. This device aims to solve the technical problems of difficult-to-disassemble and sturdy limiting structure and lack of angle adjustment and locking functions.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a modular insect-proof net. The device includes an insect-proof net with multiple splicing blocks on both sides. Each splicing block has an installation groove on the side closest to the insect-proof net. Both sides of the insect-proof net along its length are embedded in the installation grooves of the splicing blocks. A positioning through-hole is formed at the top of each splicing block, extending into the installation groove. A limiting component is provided at the positioning through-hole. The limiting component includes a limiting plate, and a limiting post is fixedly connected to the bottom of the limiting plate to restrict the movement of the insect-proof net within the installation groove. A circular through-hole is formed on the side of the splicing block away from the insect-proof net, extending into the positioning through-hole. A limiting groove is formed on one side of the limiting plate. A sleeve adapted to the limiting groove is slidably connected inside the circular through-hole. A threaded rod is threadedly connected inside the sleeve. The end of the threaded rod away from the sleeve is located on the outside of the splicing block and fixedly connected to a first knob. The threaded rod and the circular through-hole are rotatably connected via a bearing. Splicing components are provided on both sides of the splicing block.

[0009] When using the device of this technical solution, the insect-proof net is first embedded into the installation groove of the splicing block along both sides of its length. When the first knob is rotated, the threaded rod fixed to the knob rotates in the circular through hole through the bearing. Because the threaded rod is threadedly connected to the sleeve and the sleeve can only slide axially due to the restriction of the circular through hole, the sleeve will move towards the limiting plate, so that the limiting post at the bottom of the limiting plate is accurately inserted into the mesh of the insect-proof net to restrict its movement in the installation groove. At the same time, the self-locking property of the threaded drive maintains the fixed state. When the first knob is rotated in the opposite direction, the threaded rod drives the sleeve to slide in the opposite direction, and the limiting plate and the limiting post move upward, causing the limiting post to disengage from the mesh. The insect-proof net can then be removed or adjusted from the installation groove. The entire process can achieve firm fixation and convenient disassembly and assembly of the insect-proof net and the splicing block without the need for tools.

[0010] Preferably, the splicing assembly includes an insert block fixedly connected to one side of the splicing block, and a positioning groove adapted to the insert block is provided on the side of the splicing block away from the insert block.

[0011] Furthermore, the top of the splicing block has a slot extending into the positioning groove, and a pin is installed inside the slot.

[0012] Furthermore, a stop groove is provided on the outer wall of the pin, and a guide through hole adapted to the stop groove is provided on the side of the insert block away from the splicing block.

[0013] Furthermore, the top of the splicing block has a circular groove, the bottom of the circular groove has a sliding groove, a rack is slidably connected inside the sliding groove, and a positioning pin is fixedly connected to one end of the rack.

[0014] Furthermore, the end of the locating pin furthest from the rack penetrates the guide hole and extends into the stop groove.

[0015] Furthermore, a rotating shaft is rotatably connected inside the chute, and a gear is fixedly connected to the outer wall of the rotating shaft, with the gear meshing with the rack.

[0016] Furthermore, the top of the rotating shaft has a through-groove and a keyway. A key shaft is slidably connected inside the keyway. A return spring is fixedly connected between one end of the key shaft and the inside of the keyway. The other end of the key shaft extends out of the keyway and is located outside the splicing block, and a second knob is fixedly connected thereto.

[0017] Furthermore, an external gear ring is fixedly connected to the outer wall of the key shaft, located between the outer side of the splicing block and the second knob, and an internal gear groove is opened on the top of the splicing block at the circular groove, with the external gear ring meshing with the internal gear groove.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This device achieves high efficiency through a dual-optimized structure. Firstly, a limiting assembly consisting of a limiting plate, limiting post, sleeve, threaded rod, and a first knob is installed at the positioning through-hole on the top of the splicing block. The threaded rod is rotatably connected to the circular through-hole via a bearing, and the sleeve is threadedly engaged with the threaded rod and adapted to the limiting groove of the limiting plate. During operation, rotating the first knob drives the threaded rod to rotate, and the threaded transmission causes the sleeve to slide axially along the circular through-hole. The sleeve embeds into the limiting plate, and the limiting post at the bottom of the limiting plate precisely inserts into the mesh of the insect-proof net. The self-locking property of the threaded transmission secures the insect-proof net to the splicing block. The system is securely fixed. On the other hand, it features a locking structure consisting of inserts and positioning slots on both sides of the splicing block, along with pins in the slots, racks and gears in the slides, positioning pins, and a key shaft assembly with a self-locking function. During operation, the second knob is pulled up to compress the key shaft and return the spring, causing the outer gear ring to disengage from the inner gear groove. Rotating the second knob drives the gear to rotate through the shaft. The gear meshes with the rack and drives the positioning pin to retract and disengage from the stop groove. The pin can then be pulled out, and the splicing angle can be adjusted within the range by matching the inserts and positioning slots. The entire process is manual and requires no tools, significantly improving installation efficiency and protective sealing. Attached Figure Description

[0030] This specific embodiment is a modular insect-proof net, the structural diagram of which is shown below. Figure 1-8As shown, the device includes an insect-proof net 1, with multiple splicing blocks 2 on both sides of the insect-proof net 1. Each splicing block 2 has an installation groove on its side near the insect-proof net 1. Both sides of the insect-proof net 1 are embedded into the installation grooves of the splicing blocks 2 along its length. A positioning through-hole is formed at the top of each splicing block 2, extending into the installation groove. A limiting component 3 is provided at the positioning through-hole. The limiting component 3 includes a limiting plate 301. A limiting post 302, which can be inserted into the mesh of the insect-proof net 1 to restrict its movement within the installation groove, is fixedly connected to the bottom of the limiting plate 301. A circular through-hole is formed on the side of the splicing block 2 away from the insect-proof net 1, extending into the positioning through-hole. A limiting groove is formed on one side of the limiting plate 301. A sleeve 303, adapted to the limiting groove, is slidably connected inside the circular through-hole. A threaded rod 304 is threadedly connected inside the sleeve 303. The threaded rod 304 is located away from the sleeve. One end of 303 is located on the outside of the splicing block 2 and is fixedly connected to the first knob 305. The threaded rod 304 is rotatably connected to the circular through hole through the bearing. Splicing components 4 are provided on both sides of the splicing block 2. By embedding the insect net 1 into the mounting groove of the splicing block 2 along the length direction, rotating the first knob 305 drives the threaded rod 304 to rotate in the circular through hole through the bearing, so that the sleeve 303 slides along the circular through hole and pushes the limiting plate 301 down, so that the limiting post 302 is inserted into the mesh of the insect net 1 to restrict its movement and is fixed by the thread self-locking. Reverse rotation makes the limiting post 302 disengage from the mesh to complete the unlocking. This allows the insect net 1 and the splicing block 2 to be firmly fixed and easily disassembled without tools. At the same time, the splicing components 4 on both sides of the splicing block 2 can meet the combination requirements of multiple sets of insect nets, improving the overall flexibility and stability of use.

[0031] First, the splicing component 4 includes an insert block 401 fixedly connected to one side of the splicing block 2. The side of the splicing block 2 away from the insert block 401 has a positioning groove that matches the insert block 401. By matching the insert block 401 on one side of the splicing block 2 with the positioning groove on the other side of the other splicing block 2, the initial docking of the two splicing blocks 2 can be achieved by inserting the insert block 401 into the positioning groove. This provides a basic connection structure for the combination of multiple sets of insect nets, allowing the insect nets to be flexibly spliced ​​and extended as needed, improving the overall adaptability and ease of combination.

[0032] Furthermore, the top of the splicing block 2 has a slot extending into the positioning groove. A pin 402 is installed inside the slot. After the splicing block 2 is initially connected by inserting the insert 401 into the positioning groove, the pin 402 is inserted along the slot on the top of the splicing block 2 until it is inside the positioning groove. The pin 402 restricts the vertical displacement of the insert 401 in the positioning groove, further enhancing the stability of the initial connection of the two splicing blocks 2 and preventing the insert 401 from coming out of the positioning groove due to external disturbances, thus providing a basic limit for the subsequent locking structure.

[0033] Then, a stop groove is provided on the outer wall of the pin 402, and a guide through hole adapted to the stop groove is provided on the side of the insert block 401 away from the splicing block 2. After the pin 402 is inserted into the positioning groove along the slot, the stop groove on its outer wall is precisely aligned with the guide through hole on the side of the insert block 401 away from the splicing block 2. The two are adapted to provide a channel for the subsequent through locking of the positioning pin 404. The positioning pin 404 can be inserted into the stop groove through the guide through hole, which restricts the axial movement of the pin 402 in the slot, further strengthens the limiting effect of the pin 402 on the insert block 401, and improves the anti-loosening ability of the splicing block 2 connection.

[0034] Furthermore, the top of the splicing block 2 has a circular groove, and the bottom of the circular groove has a sliding groove. A rack 403 is slidably connected inside the sliding groove. One end of the rack 403 is fixedly connected to a positioning pin 404. The circular groove at the top of the splicing block 2 provides operating space, and the sliding groove at the bottom of the circular groove provides sliding guidance for the rack 403, allowing the rack 403 to move stably along the sliding groove and drive the positioning pin 404 at one end to slide synchronously. This provides a structural basis for the positioning pin 404 to subsequently pass through the guide hole and engage with the stop groove. The linkage between the rack and the positioning pin 404 ensures accurate locking position, further enhancing the stability and reliability of the splicing block 2 connection.

[0035] Secondly, the end of the positioning pin 404 away from the rack 403 passes through the guide hole and into the stop groove. The rack 403 drives the positioning pin 404 to slide along the slide groove, so that the end of the positioning pin 404 away from the rack 403 passes through the guide hole of the insert block 401 and extends into the stop groove of the pin 402, forming a lock on the pin 402 and the insert block 401, restricting the relative displacement of the two, greatly enhancing the firmness of the connection of the splicing block 2, and avoiding loosening and separation caused by external force.

[0036] Secondly, a rotating shaft 405 is rotatably connected inside the slide groove, and a gear 406 is fixedly connected to the outer wall of the rotating shaft 405. The gear 406 meshes with the rack 403. The rotating shaft 405 rotatably connected inside the slide groove drives the gear 406 fixed on the outer wall to rotate synchronously. By utilizing the meshing of the gear 406 and the rack 403, the circumferential rotation of the rotating shaft 405 is converted into the axial sliding of the rack 403 along the slide groove. This drives the positioning pin 404 at one end of the rack 403 to move precisely, providing a power transmission basis for the positioning pin 404 to pass through the guide hole, engage in the stop groove, or disengage from unlocking. This ensures the smoothness and precision of the locking and unlocking actions and improves the ease of operation.

[0037] Secondly, the top of the rotating shaft 405 has a through-hole circular groove and a keyway. A key shaft is slidably connected inside the keyway. One end of the key shaft is fixedly connected to the inside of the keyway with a return spring. The other end of the key shaft extends out of the keyway and is located outside the splicing block 2, and is fixedly connected to a second knob 407. The rotating shaft 405 has a through-hole circular groove and a keyway. The key shaft is slidably connected to the keyway, with one end connected to the keyway via a return spring and the other end extending out of the keyway and connected to the second knob 407. During operation, pulling up the second knob 407 can drive the key shaft to slide along the keyway axis and compress the return spring. Rotating the second knob 407 will transmit torque through the cooperation between the key shaft and the keyway, driving the rotating shaft 405 to rotate synchronously, thereby driving the gear 406 to mesh with the rack 403. When the second knob 407 is released, the return spring rebounds and pushes the key shaft to return to its axial position, realizing the power input for locking and unlocking and the axial return function, taking into account both the ease of operation and the reset requirements of the subsequent structure.

[0038] Finally, an external gear ring is fixedly connected to the outer wall of the key shaft, located between the outer side of the splicing block 2 and the second knob 407. An internal gear groove is opened at the top of the splicing block 2, located at the circular groove. The external gear ring meshes with the internal gear groove. Through the external gear ring located between the outer side of the key shaft and the second knob 407, the external gear ring meshes with the internal gear groove at the top circular groove of the splicing block 2. When the return spring pushes the key shaft to reset, the external gear ring and the internal gear groove are tightly meshed to restrict the rotation of the key shaft, thereby locking the rotating shaft 405 and the gear 406, preventing the positioning pin 404 from loosening due to external force. When the second knob 407 is pulled up, the external gear ring disengages from the internal gear groove, which can rotate the key shaft to drive the rotating shaft 405, realizing a reliable switch between locking and unlocking, greatly improving the anti-loosening ability of the splicing structure, while maintaining ease of operation.

[0039] When using the device of this technical solution, by embedding the insect-proof net 1 into the mounting grooves of the splicing block 2 along both sides of its length, rotating the first knob 305 drives the threaded rod 304 to rotate within the circular through hole via a bearing, causing the sleeve 303 to slide along the circular through hole and push the limiting plate 301 downward, allowing the limiting post 302 to insert into the mesh of the insect-proof net 1 to restrict its movement and maintain fixation through threaded self-locking. Reverse rotation causes the limiting post 302 to disengage from the mesh, completing the unlocking process. This achieves tool-free, secure fixing of the insect-proof net 1 and the splicing block 2, and convenient assembly and disassembly. Simultaneously, the splicing assembly 4 connects to the other splicing block 2 via the insert 401 on one side of the splicing block 2. The positioning groove on the other side of the splicing block 2 is adapted to achieve initial docking, providing a foundation for the combination of multiple sets of insect-proof nets. After docking, the pin 402 is inserted into the positioning groove along the slot at the top of the splicing block 2 to limit the vertical displacement of the insert block 401 and enhance the stability of the initial docking. The stop groove on the outer wall of the pin 402 is precisely aligned with the guide through hole on the side of the insert block 401 away from the splicing block 2, providing a channel for subsequent locking. The circular groove at the top of the splicing block 2 provides operating space, and its bottom sliding groove provides sliding guidance for the rack 403. The rack 403 can drive the positioning pin 404 at one end to slide synchronously, while the rotating shaft 405 connected in the sliding groove drives the outer side The fixed gear 406 rotates, and through the meshing of the gear 406 and the rack 403, the circumferential rotation of the rotating shaft 405 is converted into the axial sliding of the rack 403. This drives the positioning pin 404 to pass through the guide hole and extend into the stop groove, forming a double lock on the pin 402 and the insert 401, greatly enhancing the connection firmness of the splicing block 2. In addition, the top of the rotating shaft 405 has a through-hole and a keyway. The key shaft is slidably connected to the keyway, and one end is connected to the keyway through a return spring. The other end extends out of the keyway and connects to the second knob 407. During operation, pulling up the second knob 407 can drive the key shaft to slide and compress the return spring. The spring and the rotating knob transmit torque through the key shaft and keyway to drive the rotating shaft 405 to rotate. After being released, the return spring pushes the key shaft to return to its original position. At the same time, the outer toothed ring on the outer wall of the key shaft, located between the splicing block 2 and the second knob 407, meshes with the inner toothed groove at the top circular groove of the splicing block 2. During the reset, the outer toothed ring and the inner toothed groove are tightly meshed to restrict the rotation of the key shaft, thereby locking the rotating shaft 405 and the gear 406 and preventing the positioning pin 404 from loosening due to external force. Pulling up the knob will cause the outer toothed ring to disengage from the inner toothed groove, thus unlocking the device. The overall design takes into account the ease of operation, splicing flexibility, and structural anti-loosening ability, effectively improving the stability and adaptability of the device.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
