Description

Technical Field

[0001] This utility model relates to the field of mosquito repellency technology, and in particular to a structure that facilitates the observation of mosquito repellency effects. Background Technology

[0002] Mosquitoes belong to the family Culicidae in the order Diptera. They are small flying insects with piercing-sucking mouthparts. Mosquitoes are vectors for many diseases, such as malaria, dengue fever, Zika virus disease, and Japanese encephalitis, seriously threatening human health. Mosquito bites can cause itchy and swollen skin, affecting people's lives and sleep quality, and may cause allergic reactions in children, the elderly, and people with sensitive constitutions. To study mosquito repellents, it is usually necessary to collect mosquitoes and use various agents to test which drugs have a better repellent effect.

[0003] Currently, most devices used to observe mosquito repellency effects consist of a frame and gauze covering the frame. The repellent is placed inside for observation. However, existing frames have limitations; they are usually a single structure, unable to be adjusted in length according to actual needs, nor can multiple frames be connected. This significantly affects the user's practical experience, making it difficult to observe mosquito flight paths and hindering the development of mosquito repellent agents. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenient connection between frames for observing mosquito repellency in the prior art, and to propose a structure that facilitates the observation of mosquito repellency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure for convenient observation of mosquito repellency includes multiple base plates, each base plate is fixedly connected to four fixing strips, the top of each fixing strip is fixedly connected to a top plate, and the top ends of each base plate are symmetrically fixedly connected to a first fixing seat and a second fixing seat, respectively. It also includes a cylinder fixedly connected to the first fixing seat, the top of the cylinder is provided with a limit groove, and an insertion rod is rotatably connected to the second fixing seat, the insertion rod is fixedly connected to a limit rod.

[0007] Preferably, an extrusion plate is slidably connected inside the cylinder, and a spring is fixedly connected between the extrusion plate and the cylinder.

[0008] Preferably, the limiting groove includes a straight groove, a horizontal groove, and a locking groove.

[0009] Preferably, each of the base plate, fixing strip, and top plate is transparent.

[0010] Preferably, the insertion rod passes through the second fixed base and is rotatably connected to the second fixed base. A connecting rod is fixedly connected to one side of the insertion rod, and a handwheel is rotatably connected to the connecting rod.

[0011] Preferably, a mesh screen is fixedly installed between each of the bottom plates and the top plates.

[0012] Preferably, the limiting rod is slidably connected to the limiting groove.

[0013] Preferably, each of the top plates is hinged to an L-shaped friction plate, and a torsion spring is fixedly connected between the L-shaped friction plate and the top plate. Each of the bottom plates is fixedly connected to a rectangular frame, and a sliding plate is slidably connected inside the rectangular frame. A pull plate is fixedly connected to the L-shaped friction plate.

[0014] Compared with the prior art, this utility model provides a structure that facilitates observation of mosquito repellency, and has the following beneficial effects:

[0015] 1. This structure facilitates observation of mosquito repellency. Two rods on the two second fixing seats on the top plate are aligned with two cylinders on the two first fixing seats on another top plate and inserted. The rods contact the compression plate and compress the spring. Then, the limiting rod on the rod passes through the straight groove and reaches the horizontal groove. Turning the two handwheels rotates the connecting rod, causing the rod to rotate and the limiting rod to rotate. After the limiting rod rotates into the slot, the handwheel is released. The spring applies a reverse elastic force to the compression plate and the rod towards the outside of the cylinder, causing the limiting rod to fit tightly against the inner wall of the slot. This allows multiple top plates to be quickly connected. After the multiple top plates are connected, the mosquito repellent is placed on the outermost bottom plate. Then, the mesh is attached to the fixing strip using a magnet to complete the installation, and the mosquito repellency effect can be observed.

[0016] 2. This structure facilitates observation of the mosquito repellency effect. By pushing the handwheel, the insertion rod is driven to squeeze the compression plate again, causing the limiting rod to slide from the slot to the horizontal slot. Then, by rotating the two handwheels, the limiting rod can be driven into the straight slot. After that, it can be released, and the spring will automatically pop out the insertion rod, allowing the top plates to separate and complete the quick disassembly. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example 1, refer to Figures 1-6A structure for convenient observation of mosquito repellency includes multiple base plates 1, each base plate 1 is fixedly connected to four fixing strips 2, and a top plate 3 is fixedly connected to the top of each fixing strip 2. A first fixing seat 4 and a second fixing seat 5 are symmetrically fixedly connected to the top ends of each base plate 1. The structure also includes a cylinder 6 fixedly connected to the first fixing seat 4. A limiting groove 7 is opened on the top of the cylinder 6. An insertion rod 8 is rotatably connected to the second fixing seat 5, and a limiting rod 9 is fixedly connected to the insertion rod 8. In use, the second fixing seat 5 on one top plate 3 is aligned with the first fixing seat 4 on the other top plate 3. The insertion rod 8 on the second fixing seat 5 is inserted into the cylinder 6. Then, the insertion rod 8 is rotated to allow the limiting rod 9 to enter the limiting groove 7 of the cylinder 6, so that the two top plates 3 can be quickly connected and fixed.

[0030] An extrusion plate 10 is slidably connected inside the cylinder 6. A spring 11 is fixedly connected between the extrusion plate 10 and the cylinder 6. When the insertion rod 8 enters the cylinder 6, it will first come into contact with the extrusion plate 10, causing the extrusion plate 10 to compress the spring 11. After the limiting rod 9 is fixed to the limiting groove 7, the spring 11 will simultaneously apply a reverse thrust to the extrusion plate 10 and the insertion rod 8, so that the limiting rod 9 and the limiting groove 7 fit tightly together, thereby making the docking effect between the top plates 3 better and more stable.

[0031] The limiting groove 7 includes a straight groove 701, a horizontal groove 702, and a locking groove 703. When the insert rod 8 enters the cylinder 6, the limiting rod 9 will first pass through the straight groove 701 and then enter the horizontal groove 702. Then, by rotating the insert rod 8, the limiting rod 9 can be driven into the locking groove 703. After releasing the insert rod 8, the limiting rod 9 will fit tightly against the inner wall of the locking groove 703 under the action of the spring 11, which is convenient for the user to quickly connect and thus helps the user to easily observe the mosquito repellency effect.

[0032] Each base plate 1, fixing strip 2, and top plate 3 is transparent, making it easier for staff to observe the mosquito repellency effect.

[0033] The insertion rod 8 passes through the second fixed seat 5 and is rotatably connected to the second fixed seat 5. A connecting rod 12 is fixedly connected to one side of the insertion rod 8, and a handwheel 13 is rotatably connected to the connecting rod 12. After the limiting rod 9 is inserted into the horizontal groove 702, the connecting rod 12 can be rotated by rotating the handwheel 13. The connecting rod 12 drives the insertion rod 8 to rotate, and the insertion rod 8 can drive the limiting rod 9 to rotate into the slot 703. This is convenient and simple to operate.

[0034] Each base plate 1 and top plate 3 is fixedly installed with a mesh 14. After multiple top plates 3 and base plates 1 are connected, the mesh 14 can be attracted to the fixing strip 2 with a strong magnet, which makes it easy to install the mesh 14. It should be noted that the fixing strip 2 is made of stainless steel, which makes it easy for the magnet to attract.

[0035] The limiting rod 9 is slidably connected to the limiting groove 7.

[0036] Example 2, refer to Figures 7-9 Similar to Embodiment 1, but with a further improvement, each top plate 3 has an L-shaped friction plate 15 hinged to its top, and a torsion spring 16 is fixedly connected between the L-shaped friction plate 15 and the top plate 3. Each bottom plate 1 has a rectangular frame 17 fixedly connected, and a sliding plate 18 is slidably connected within the rectangular frame 17. A pull plate 19 is fixedly connected to the L-shaped friction plate 15. After the operator completes the assembly according to the required number or length, to further observe the mosquito repellency effect, the pull plate 19 can be pulled to one side to move the L-shaped friction plate 15 and... Once the slide plate 18 detaches, simply press down on the slide plate 18 and slide it within the rectangular frame 17 to adjust the size of the rectangular hole in the rectangular frame 17. The deeper the slide plate 18 slides down, the smaller the space in the rectangular frame 17 becomes. After placing the repellent at one end, if mosquitoes can pass through the narrow space of the rectangular frame 17 to the other end, it proves that the repellent is more effective. The L-shaped friction plate 15 allows the slide plate 18 to stop at any position on the rectangular frame 17, making it easy to adjust the space size and helping to better observe the mosquito repellency effect.

[0037] In this utility model, during use, the operator places multiple base plates 1 according to the required number or length. Then, the two insert rods 8 on the two second fixing seats 5 on the top plate 3 are aligned with the two cylinders 6 on the two first fixing seats 4 on another top plate 3 and inserted. The insert rods 8 abut against the extrusion plate 10 and compress the spring 11. Then, the limiting rod 9 on the insert rod 8 passes through the straight groove 701 and reaches the transverse groove 702. The two handwheels 13 are then rotated to drive the connecting rod 12 to rotate, causing the insert rod 8 to drive the limiting rod 9 to rotate. After the limiting rod 9 rotates into the slot 703, the handwheel 13 is released. The spring 11 applies a reverse elastic force to the extrusion plate 10 and the insert rod 8 towards the outside of the cylinder 6, causing the limiting rod 9 to fit tightly against the inner wall of the slot 703. This allows for quick connection between multiple top plates 3. After connection, the insect repellent is placed on the outermost bottom plate 1. Then, the mesh 14 is attached to the fixing strip 2 using a magnet to complete the installation. The insect repellency effect can then be observed. If mosquitoes fly towards the bottom plate 1 without the insect repellent, it proves that the insect repellent is effective. When disassembly is required, simply push the handwheel 13 to push the insertion rod 8 to press the compression plate 10 again, causing the limiting rod 9 to slide from the slot 703 to the horizontal slot 702. Then, turn both handwheels 13 to move the limiting rod 9 into the straight slot 701. Then, release the handwheels. The spring 11 will automatically pop out the insertion rod 8, allowing the top plates 3 to separate and complete the quick disassembly.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
