Description

Technical Field

[0001] This utility model relates to the field of forestry pest control, and in particular to an installation structure and a pest trapping device. Background Technology

[0002] The primary natural enemy of trees during their growth is various pests. When pests invade or parasitize trees, they cause a series of abnormal changes in the plant's morphology, tissues, or physiology, leading to poor growth and development, reduced yield and quality, and even plant death and ecological degradation. To better ensure plant growth, people use various trapping devices to help eliminate pests from trees, enabling early warning and control of tree pests.

[0003] Due to limited installation conditions in forests, trapping devices are mostly installed on tree trunks on-site. To accommodate tree trunks of different diameters, existing trapping device installation structures are often adaptable to different tree diameters, using rigid materials for clamping and securing the device. This method offers the advantage of quick installation compared to flexible ropes and belts. However, since most tree trunks are non-standard cylindrical shapes, existing rigid material installation structures struggle to achieve complete or near-complete contact with trunks of varying shapes and sizes. To ensure a secure installation and increase the static friction between the installation structure and the trunk, operators often apply significant clamping force, causing a small contact area between the trunk and the installation structure to bear a large load. Over time, this can damage the tree itself.

[0004] Based on the above, it is necessary to design an installation structure for an insect trapping device that can achieve rapid installation and reduce the damage to the tree trunk caused by localized stress. Utility Model Content

[0047] Embodiment 1

[0048] Reference Figures 1-4 For the present embodiment provides a mounting structure, including clamping assembly 1 and fit component 2. Clamping assembly 1 with hard material, such as plastic metal parts and so on, can be applied to the need to install the object of the trunk of a basic clamping force, and facilitate and pest trapping device and other installation between the connection and fixed, fit component 2 with flexible soft material, such as pull rope, belt, rubber belt and so on, in straight after the tight self-adaptation and between the special-shaped tree trunk fit.

[0049] Specifically, clamping assembly 1 includes two groups of clamping parts 11, two groups of clamping parts 11 form a containing groove 12 can accommodate installation object between the two groups of clamping parts 11, movable connection, and then can be through the movement of the two clamping parts 11 between the interval adjustment containing groove 12 size, to adapt to the different diameter size of the installation object; between the two groups of clamping parts 11 is also connected for fixing the size of the containing groove 12 locking part 13, when the two groups of clamping parts 11 between the movable to the installation object in the containing groove 12 extrusion contact, can be through the locking part 13 limit the size of the containing groove 12 between the two groups of clamping parts 11 increase, so that the two groups of clamping parts 11 to the installation object exert a basic clamping force.

[0050] Further, fit component 2, including the flexible band 21 arranged in the two groups of clamping parts 11 inside, and the tightening part 22 arranged in the clamping part 11 side, the tightening part 22 for pulling the flexible band 21 to the center of the containing groove 12. The tightening part 22 for applying tension to the flexible band 21, in the present embodiment, the flexible band 21 can be specifically selected by pull rope or belt, after the two groups of clamping parts 11 to the installation object exerting clamping force, through the tightening part 22 pull the flexible band 21 tight extrusion fit to the installation object in the containing groove 12, increase the adaptive contact area.

[0051] Among them, the two groups of clamping parts 11 through the rotation center 111 rotating connection, the two groups of clamping parts 11 away from the end of the rotation center 111 between the notch 112 formed with the containing groove 12 communication, before installation, through the rotation center 111 rotating two groups of clamping parts 11, so that the size of the notch 112 is not less than the installation object, will be installed through the notch 112 into the containing groove 12, then through the rotation center 111 reverse rotation of the two groups of clamping parts 11, so that the notch 112 decreases, until the two groups of clamping parts 11 to the installation object extrusion. In some embodiments, the rotation center 111 for the shaft or hinge, the maximum size of the notch 112 and the size of the installation object adaptation.

[0052] Preferably, the locking part 13 comprises a torsion spring 131 nested on the rotating shaft, and the two ends of the torsion spring 131 are connected with the two groups of clamping parts 11 respectively. The torsion spring 131 is a common part structure in the prior art, so that a torsion force is generated between the two clamping parts 11, when the two clamping parts 11 are relatively rotated to increase the gap 112, the torsion spring 131 is deformed to accumulate the torsion force, after the installation object is put into the accommodating groove 12 through the gap 112, the two clamping parts 11 are stopped from rotating, and the two clamping parts 11 are automatically reversely rotated under the reset action of the torsion force to clamp the installation object. By arranging the torsion spring 131, a range value of the clamping force is provided, that is, the maximum torsion force generated by the torsion spring 131 is set to be not obvious to the installation object, so as to prevent the excessive extrusion force on the installation object; meanwhile, the minimum torsion force generated by the torsion spring 131 should ensure that there is a basic value of the static friction force between the installation object, such as not less than the weight of the installation structure, so as to facilitate use. In addition, the clamping force is automatically provided by the torsion spring 131, which can facilitate the installation operation, and the two clamping parts 11 can also be accommodated under the action of the torsion spring 131 when not in use.

[0053] Working principle: before installation, the two groups of clamping parts 11 are rotated through the rotating center 111, when the two clamping parts 11 are relatively rotated to increase the gap 112, the torsion spring 131 is deformed to accumulate the torsion force, after the installation object is put into the accommodating groove 12 through the gap 112, the two clamping parts 11 are stopped from rotating, and the two clamping parts 11 are automatically reversely rotated under the reset action of the torsion force to clamp the installation object.

[0054] Embodiment 2

[0055] Reference Figures 1-7 For the second embodiment of the utility model, different from the previous embodiment, the embodiment provides specific implementation structures of the accommodating groove 113, the limiting piece 114, the staggered groove 115 and the tightening part 22, which facilitates the tightening use of the flexible belt 21.

[0056] Specifically, the inner side of the clamping part 11 is provided with the accommodating groove 113 matched with the flexible belt 21, and the limiting piece 114 for blocking the flexible belt 21 from moving out of the accommodating groove 113 completely, the flexible belt 21 in the accommodating groove 113 is limited and blocked by the limiting piece 114, so that the flexible belt 21 is stored in the accommodating groove 113, and the accommodating groove 113 is located in the clamping part 11 and on the outside of the installation object in the accommodating groove 12, which facilitates use; meanwhile, the flexible belt 21 is limited to ensure that the flexible belt 21 can be bundled towards the center of the accommodating groove 12 to realize self-adaptive fitting to the installation object during tightening.

[0057] The flexible belt 21 is provided with two groups and is arranged in the installation groove 113 of the two groups of clamping parts 11. The end of the two groups of flexible belts 21 close to the gap 112 is provided with a detachable connecting piece 211. Before installation, the connecting pieces 211 of the two flexible belts 21 are detached, so that the installation object can enter the containing groove 12 through the gap 112. Then, the two flexible belts 21 are connected by the connecting pieces 211 to be integrated, so that when one end of the flexible belt 21 is pulled and tightened, the two flexible belts 21 will be pulled and tightened at the same time. The detachable structure of the connecting piece 211 can be selected from common clamping structures, threaded connection structures, etc., and the preferred spring clamping structure is shown in the figure. The end of the two flexible belts 21 is provided with a connecting block, and the two connecting blocks are respectively provided with a slidingly connected elastic plug 211a and a fixedly arranged plug sleeve 211b matched with the elastic plug 211a. The elastic plug 211a and the connecting block are connected by a spring 211c, which facilitates quick installation and disassembly. It is worth noting that when the installation groove 113 is arranged inside the clamping part 11, the size of the connecting piece 211 needs to be matched with the installation groove 113 to prevent interference and block the installation groove 113, thereby affecting the tightening of the flexible belt 21.

[0058] In some embodiments, the connecting piece 211 at the end of the two flexible belts 21 is provided with magnetism, and the end of the two clamping parts 11 close to the gap 112 is also provided with a magnetic connecting piece 211. In this way, the connecting piece 211 can be temporarily fixed to the end of the clamping part 11 by magnetic force when not in use. When needed, the gap 112 is increased to overcome the magnetic force between the connecting piece 211 and the end of the clamping part 11 to separate them, which is convenient to use.

[0059] One end of one group of flexible belts 21 close to the rotation center 111 is fixedly connected with the clamping part 11, and the other end of the other group of flexible belts 21 close to the rotation center 111 is connected with the tightening part 22. After the two flexible belts 21 are connected by the connecting piece 211, the flexible belt 21 connected with the tightening part 22 is pulled, so that the integrated flexible belt 21 is collected to the installation object in the containing groove 12.

[0060] Further, the limiting member 114 is fixedly arranged at one side of the accommodating groove 113 close to the containing groove 12, or / and is slidingly arranged in the accommodating groove 113, and the flexible belt 21 is gathered from the two sides of the limiting member 114 to the containing groove 12. When the limiting member 114 is fixedly arranged in the accommodating groove 113, the limiting member 114 can be a fixed baffle, which is preferably arranged at the middle position of the clamping part 11 to adapt to most use scenarios; when the limiting member 114 is slidingly arranged in the accommodating groove 113, the limiting member 114 can be a sliding rod, and the flexible belt 21 can be slidingly connected with the sliding rod, so that when the flexible belt 21 is tightened, the sliding rod slides in the accommodating groove 113 to adaptively adjust the position of the limiting member 114, so that the fitting state between the flexible belt 21 and the installation object is better, and more special-shaped installation objects can be conveniently adapted.

[0061] In the embodiment, the clamping part 11 is provided with the arc-shaped clamping segment 116, which can adapt to the installation object such as a tree trunk. When the clamping segment 116 is rotated to the position where the gap 112 is 0 through the rotation center 111, if the size or shape of the installation object causes the clamping segment 116 to still fail to press the installation object, the two clamping segments 116 can continue to rotate towards each other through the mutually adapted misaligned grooves 115 until the installation object is clamped. The misaligned grooves 115 improve the applicability of the installation object.

[0062] It is worth noting that the accommodating groove 113 of one group of clamping parts 11 is arranged in the clamping segment 116, and the accommodating groove 113 of the other group of clamping parts 11 is arranged in the corresponding misaligned groove 115. Since the clamping segment 116 and the misaligned groove 115 are correspondingly arranged, the flexible belt 21 in the corresponding accommodating groove 113 can be connected at the same height without misalignment and the like, preventing the flexible belt 21 from being tangled.

[0063] Further, the misaligned grooves 115 and the clamping segments 116 are spaced apart along the axial direction of the rotation center 111 by not less than two groups. Multiple groups are arranged along the axial direction to increase the contact area of the clamping segment 116 and the installation object, ensuring the stability of the installation, especially when the installation structure is under load, the lower clamping segment 116 will provide good support. The limiting member 114 in each group of misaligned grooves 115 or clamping segments 116 of the same clamping part 11 is aligned and arranged along the axial direction of the rotation center 111. Each clamping part 11 is provided with a flexible belt 21, so that the gathering tendency of each layer of flexible belt 21 is close, the contact area of the gathering force of each layer is close, and the flexible belts 21 are prevented from being tangled.

[0064] Preferably, the tightening part 22 comprises a threaded rod 221 connected with the clamping part 11, a sliding block 222 threaded on the surface of the threaded rod 221, and a guide 223 arranged on one side of the clamping part 11 and slidingly connected with the sliding block 222. The sliding block 222 is fixedly connected with the end of the flexible belt 21, and the sliding direction of the sliding block 222 is parallel to the axial direction of the threaded rod 221. The guide 223 can be a guide rod parallel to the axial direction of the threaded rod 221, or a guide groove arranged on the surface of the sliding block 222, and then a guide column arranged on one side of the clamping part 11.

[0065] The rest of the structure is the same as that of Example 1.

[0066] Working principle: before installation, the connecting piece 211 between the two flexible belts 21 is disassembled, then the two sets of clamping parts 11 are rotated through the rotating center 111, so that the installation object is put into the containing groove 12 through the gap 112, and when the flexible belt 21 needs to be tightened, the threaded rod 221 is rotated to make the sliding block 222 move away from the clamping part 11 through the guide 223, and then the flexible belt 21 is pulled, until the flexible belt 21 is pulled tight, the flexible belt 21 is attached to the installation object in the containing groove 12 for extrusion, until the flexible belt 21 completely extrudes the installation object, and the threaded rod 221 is stopped rotating, because the screw rotation direction of the threaded rod 221 is perpendicular to the stress direction of the flexible belt 21, so the threaded rod 221 will not be loosened in the opposite direction, and the use effect is stable.

The bottom of the connecting frame 32 is detachably connected with a storage disc 44 for storing the pest corpses, the pest corpses killed by electricity fall into the storage bin 441 of the storage disc 44 under the action of gravity, and when the corpses collected in the storage disc 44 are enough, the storage disc 44 can be disassembled and processed, and then reinstalled and replaced. The disassembly structure of the storage disc 44 can be selected as a common threaded connection structure, and is detachably connected through bolts.

[0071] The power supply assembly 5 is electrically connected with the trapping lamp 41 and the killing electric net 42, and includes at least one of a solar panel, a detachable mobile power supply and an electrical connection port arranged at the top of the connecting frame 32. The solar panel can store electricity by using the sunlight in the wild forest area, at this time, the protective plate at the top of the connecting frame 32 should be made of transparent material to ensure that the light can pass through, and the detachable mobile power supply such as a battery or the electrical connection port can be directly plugged in for use.
