Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1 - 5 , a forest nursery pest trap, including a base 1, a hollow rod 2 is vertically and fixedly installed on the upper surface of the base 1, an insertion rod 3 is slidably inserted into the hollow rod 2, a mounting plate is fixedly installed at the top of the insertion rod 3, an insect attracting lamp is fixedly installed on the upper surface of the mounting plate, and an electric grid 4 for covering the insect attracting lamp is fixedly installed on the upper surface of the mounting plate.

[0024] A mounting ring 5 is sleeved at the top of the hollow rod 2. Symmetrically fixed on the inner wall of the mounting ring 5 are mounting rods 6. The ends of the two mounting rods 6 are fixedly connected to the surface of the hollow rod 2. An L-shaped locking rod 7 is slidably sleeved on the mounting rod 6. The locking rod 7 is connected to the mounting ring 5 through a telescopic member. The telescopic member includes a telescopic spring 9 sleeved on the mounting rod 6. The two ends of the telescopic spring 9 are respectively fixedly connected to the mounting ring 5 and the locking rod 7. A plurality of locking holes 8 for the ends of the locking rod 7 to insert are horizontally opened on the surface of the insertion rod 3. Through holes for the ends of the two locking rods 7 to pass through are symmetrically opened on the surface of the hollow rod 2.

[0025] By controlling the two locking rods 7 to move away from each other, after the ends of the two locking rods 7 that are close to each other are removed from the locking holes 8, the locking between the hollow rod 2 and the insertion rod 3 can be released. Then, by controlling the insertion rod 3 to move vertically in the hollow rod 2, the total length of the insertion rod 3 and the hollow rod 2 can be changed. Until the insect attracting lamp and the electric grid 4 located at the top of the insertion rod 3 move to a suitable height position, at this time, finely adjust the vertical movement of the insertion rod 3. After the locking hole 8 closest to the two locking rods 7 corresponds to the positions of the ends of the two locking rods 7, release the two locking rods 7. The two locking rods 7 will quickly move back under the elastic potential energy of the telescopic spring 9, and the ends that are close to each other will be inserted into the locking holes 8 corresponding to their own positions, thus completing the locking between the hollow rod 2 and the insertion rod 3. The ground clearance of the insect attracting lamp and the electric grid 4 can be adjusted, so that the pests that the insect attracting lamp can trap are no longer in a certain height area, improving the practicability of the device.

[0026] On the upper surface of the base 1, a plurality of circular openings are provided. Vertically fixed inside the circular openings are buried rods 10. At the top of the buried rod 10, an installation groove 11 is vertically provided. On the surface of the bottom end of the buried rod 10, a through hole 12 is provided. Horizontally and slidably inserted into the through hole 12 is a positioning rod 13. One end of both the positioning rod 13 and the buried rod 10 is tapered. A plurality of positioning rods 13 are controlled to move laterally together through a pressing component. The pressing component includes a threaded rod 14, a sliding ring 15 threadedly sleeved on the threaded rod 14, a plurality of I-shaped blocks 16, and a plurality of inclined plates 17. The threaded rod 14 is vertically rotatably installed on the upper surface of the base 1. The rotation of the sliding ring 15 is restricted by a restricting component. The restricting component includes two restricting rods 20 vertically and fixedly installed on the upper surface of the base 1. The sliding ring 15 is slidably sleeved on the plurality of restricting rods 20. An installation plate is fixedly sleeved on the positioning rod 13. A plurality of inclined plates 17 are respectively fixedly installed at the tops of the plurality of installation plates and are each provided with an inclined opening 18. A plurality of I-shaped blocks 16 are respectively slidably arranged in the plurality of inclined openings 18. On the lower surface of the sliding ring 15, a plurality of connecting rods 19 are fixedly installed in a circumferential shape. The bottom ends of the plurality of connecting rods 19 are respectively fixedly connected to the surfaces of the plurality of I-shaped blocks 16.

[0027] When the trap moves to a suitable placement position, at this time, control the plurality of buried rods 10 to be vertically inserted into the soil until the base 1 contacts the ground. Then, by rotating the threaded rod 14, the sliding ring 15 threadedly sleeved on the threaded rod 14 will drive the plurality of I-shaped blocks 16 to move vertically under the restricting action of the plurality of restricting rods 20. The plurality of I-shaped blocks 16 will respectively slide in the plurality of inclined openings 18. When the I-shaped block 16 moves upward, at this time, under the action of inclined surface pressing, the positioning rod 13 will move towards the inside of the installation groove 11. And when the I-shaped block 16 moves downward, at this time, the positioning rod 13 will move towards the outside of the installation groove 11. Control the plurality of positioning rods 13 to move towards the outside of the installation groove 11 until the end of the positioning rod 13 moves out of the through hole 12 and is inserted into the soil. At this time, the buried rod 10 will be in a T shape in the soil, thereby increasing the grip of the buried rod 10 and improving the stability of the device when installed in the soil.

[0028] And when it is necessary to pull out the buried rod 10 from the soil, just rotate the threaded rod 14 to control the sliding ring 15 to drive the plurality of I-shaped blocks 16 to move upward, so that the plurality of positioning rods 13 all move towards the inside of the installation groove 11. Until the end of the positioning rod 13 moves back into the through hole 12, then pull out the buried rod 10 from the soil, which is convenient and fast.

[0029] In the present utility model, by controlling the two locking rods 7 to move away from each other, after the end portions of the two locking rods 7 that are close to each other are moved out of the locking openings 8, the locking between the hollow rod 2 and the insertion rod 3 can be released. Then, by controlling the vertical movement of the insertion rod 3 within the hollow rod 2, the total length of the insertion rod 3 and the hollow rod 2 can be changed. Until the insect attracting lamp and the electric grid 4 located at the top of the insertion rod 3 are moved to a suitable height position, at this time, finely adjust the vertical movement of the insertion rod 3 so that the locking opening 8 closest to the two locking rods 7 moves to a position corresponding to the end portions of the two locking rods 7, and then release the two locking rods 7. The two locking rods 7 will quickly move back to their original positions under the elastic potential energy of the telescopic member, and the end portions that are close to each other will be inserted into the locking openings 8 corresponding to their respective positions, thereby completing the locking between the hollow rod 2 and the insertion rod 3. The ground clearance height of the insect attracting lamp and the electric grid 4 can be adjusted, so that the pests that can be trapped and killed by the insect attracting lamp are no longer in a certain height range, improving the practicability of the device.

[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, should be covered by the protection scope of the present utility model.
