Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insect catching, in particular to a novel insect catching net. Background Art
[0002] Insect nets are tools used to catch fast-flying, jumping and agile insects. Different insect nets are used according to the habits and living environments of different insects. Insect nets can generally be divided into three types: capture nets, sweep nets and water nets. Sweep nets are suitable for sweeping large areas of bushes while walking and catching multiple insects at one time; water nets are specifically used to catch aquatic insects; capture nets are suitable for purposeful catching of insects and are more commonly used in scientific research.
[0003] There are two ways to use the fishing net. One is that when the insect enters the net, the bottom of the net bag is swung upwards, and the bottom of the net bag and the insect are turned upside down; the other is that when the insect enters the net, the net handle is turned downward to seal the insect at the bottom of the net bag.
[0004] At present, a domestic patent with authorization announcement number CN216674400U discloses an insect catching net with telescopic and angle adjustment functions, including an insect catching net, a connecting rod, a matching rod and a fixed block, the insect catching net is movably connected to the connecting rod, the connecting rod is movably connected to the matching rod, the fixed block is fixedly connected to the matching rod, a cavity is opened inside the fixed block, a positioning device is fixedly installed on the bottom of the inner wall of the cavity, a supporting block is fixedly connected to the top of the inner wall of the cavity, and transmission devices are fixedly installed on the left and right sides of the supporting block.
[0005] The above-mentioned insect catching net with telescopic and angle adjustment functions has the advantages of adjusting the angle of the insect catching net, better fixing effect after telescopic, and avoiding loosening and jamming; however, the technical solution still has the following shortcomings:
[0006] When using the above-mentioned insect catching net with telescopic and angle adjustment functions to catch insects, after an insect enters the net, if the net bag is swung or the net mouth is not turned down quickly, the insect is easy to escape; in addition, the above-mentioned insect catching net does not have the function of temporarily storing captured insects. After each insect is captured, the insect in the net needs to be taken out in time before the insect catching net can be used again to carry out insect catching work, otherwise the captured insect is also easy to escape from the net, which is not conducive to improving the insect catching efficiency. Utility Model Content
[0007] The utility model aims to provide a novel insect catching net to solve the problem that the existing insect catching nets mentioned in the background art are prone to cause insects to escape when catching insects and cannot temporarily store the captured insects.
[0008] In order to solve the above problems, the utility model provides the following technical solutions:
[0009] A novel insect catching net comprises a rod body, a net frame and a net body, wherein the net frame is installed on the top of the rod body, the net body is installed on the net frame, an anti-escape component is arranged inside the net body, the anti-escape component comprises a hollow frustum tube, a circular cover plate, a rotating shaft and a torsion spring; one end of the hollow frustum tube is fixedly connected to the inner side of the net body, the other end of the hollow frustum tube is rotatably connected to the circular cover plate via a rotating shaft, a torsion spring is arranged on the rotating shaft, one end of the torsion spring abuts against the hollow frustum tube, and the other end of the torsion spring abuts against the circular cover plate; an opening structure is arranged at one end of the net body.
[0010] Furthermore, the opening structure is a zipper.
[0011] Furthermore, the rod body includes a telescopic member.
[0012] Furthermore, the telescopic member includes an inner rod, an outer rod, a positioning hole, a positioning block, a spring and a limit block; one end of the positioning block is fixedly connected to the limit block, the inner rod is matched with the hollow outer rod, and the outer rod is provided with a plurality of positioning holes that are compatible with the positioning block. The positioning block passes through the inner rod and the outer rod, and the two ends of the spring are respectively fixedly connected to the limit block and the inner wall of the inner rod.
[0013] Furthermore, one end of the outer rod is provided with anti-slip grooves.
[0014] Furthermore, the area of the circular cover plate is larger than the opening area of the hollow frustum tube.
[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0016] When the utility model is in use, the user holds the rod body and waves the opening of the net body toward the insects to be caught. During the waving of the net body, part of the air flow converges in the hollow conical tube. Due to the relativity of the movement, the air flow and the insects entering the net body move backwards relative to the direction in which the net body is swung. Under the action of the air flow, the circular cover plate rotates and opens, thereby allowing the insects that also move relatively backwards to pass through the hollow conical tube. When the user stops waving the net body, the circular cover plate returns to a closed state under the action of the torsion spring, thereby closing the captured insects, preventing the captured insects from escaping, and temporarily storing the captured insects.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] See also Figure 1 to Figure 5 , the utility model provides a technical solution:
[0032] A novel insect catching net comprises a rod body 1, a net frame 2 and a net body 3. The net frame 2 is installed on the top of the rod body 1, and the net body 3 is installed on the net frame 2. An anti-escape component 4 is arranged inside the net body 3. The anti-escape component 4 comprises a hollow frustum tube 4.1, a circular cover plate 4.2, a rotating shaft 4.3 and a torsion spring 4.4. One end of the hollow frustum tube 4.1 is fixedly connected to the inner side of the net body 3, and the other end of the hollow frustum tube 4.1 is rotatably connected to the circular cover plate 4.2 through the rotating shaft 4.3. A torsion spring 4.4 is arranged on the rotating shaft 4.3, and one end of the torsion spring 4.4 abuts against the hollow frustum tube 4.1, and the other end of the torsion spring 4.4 abuts against the circular cover plate 4.2.
[0033] When the utility model is in use, the user holds the rod body 1 and waves the opening of the net body 3 toward the insects to be caught. During the waving of the net body 3, part of the air flow converges in the hollow conical tube 4.1. Due to the relativity of movement, the air flow and the insects entering the net body 3 move backwards relative to the direction in which the net body 3 is waved. Under the action of the air flow, the circular cover plate 4.2 rotates and opens, so that the insects that also move relatively backwards pass through the hollow conical tube 4.1. When the user stops waving the net body 3, the circular cover plate 4.2 returns to the closed state under the action of the torsion spring 4.3, thereby closing the captured insects and temporarily storing the captured insects.
[0034] One end of the net body 3 is provided with an opening structure, which is a zipper 5; when a certain number of insects are captured, the insects stored at one end of the net body 3 can be driven to other insect storage spaces such as insect collecting bottles by opening the zipper 5.
[0035] The rod body 1 includes a telescopic member, which includes an inner rod 1.1, an outer rod 1.2, a positioning hole 1.3, a positioning block 1.4, a spring 1.5 and a limit block 1.6; one end of the positioning block 1.4 is fixedly connected to the limit block 1.6, the inner rod 1.1 is matched with the hollow outer rod 1.2, and the outer rod 1.2 is provided with a plurality of positioning holes 1.3 that are compatible with the positioning block 1.4. The positioning block 1.4 runs through the inner rod 1.1 and the outer rod 1.2, and the two ends of the spring 1.5 are respectively fixedly connected to the limit block 1.6 and the inner wall of the inner rod 1.1.
[0036] When the utility model is in use, the user presses the positioning block 1.4 to move the positioning block 1.4 out of the positioning hole 1.3 provided on the outer rod 1.2, and then pulls the inner rod 1.1 to adjust the length of the rod body 1 according to the actual needs of catching insects, until the positioning block 1.4 moves to other suitable positioning holes 1.3. At this time, the positioning block 1.4 is ejected under the action of the spring 1.5, so that the positioning block 1.4 fixes the inner rod 1.1 and the outer rod 1.2.
[0037] In addition, the limiting block 1.6 fixedly connected to one end of the positioning block 1.4 can limit the position of the positioning block 1.4 to prevent the positioning block 1.4 from being separated from the rod body 1 under the elastic force of the spring 1.5, thereby avoiding malfunction of the utility model.
[0038] One end of the outer rod 1.2 is provided with an anti-skid pattern 1.7 to facilitate the user's grip on the rod body 1 and prevent slipping.
[0039] The area of the circular cover 4.2 is larger than the opening area of the hollow truncated cone tube 4.1, ensuring the tight closure of the circular cover 4.2 and the opening of the hollow truncated cone tube 4.1, while also ensuring that the circular cover 4.2 can only be rotated open toward one end of the net body 3 to prevent captured insects from escaping.
[0040] When implementing the technical solution of the present application, the material of the mesh body 1 can be nylon yarn, and the inner rod 1.1 and the outer rod 1.2 can be common hollow stainless steel tubes, and the present application does not make any limitation on this.
[0041] Finally, it should be noted that when implementing the technical solution of the present application, the torsion spring 4.1 should preferably be a torsion spring with a smaller torque, and the circular cover plate 4.2 should preferably be a lightweight plastic material such as polypropylene, so that when the net body 3 is waved, the circular cover plate 4.2 is more likely to rotate and open under the action of air flow, making it easier for insects captured by the net body 3 to pass through the hollow conical tube 4.1, thereby improving the insect capture effect.
[0042] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
