Description

Technical Field

[0001] The utility model relates to the technical field of insect attracting plates, in particular to a magnetic bracket of an insect attracting plate which is easy to install. Background Art

[0002] In the process of agricultural planting, in order to ensure agricultural output, it is necessary to kill agricultural pests. In the process of physical killing of pests, pests are killed by devices such as insect trap lamps and insect trap boards. The insect trap boards need to be used in conjunction with brackets during use to complete the insect trap board's killing of pests. However, the existing insect trap boards and brackets still have certain use defects during use, such as:

[0003] The utility model announcement number CN213307024U discloses an insect trap bracket, which relates to the field of insect trapping devices, and in particular to an insect trap bracket, which includes a main rod, one end of which is used to be fixed on the ground, and the other end is connected to a clamping plate, and the clamping plate is connected to a fixing piece for fixing the insect trap, which has the effect of facilitating the fixing, replacement, and height adjustment of the insect trap;

[0004] In the above document, the utility model also improves the fixing method of the traditional insect attracting board, but the utility model is only applicable to single-sided insect attracting boards, while most insect attracting boards are double-sided insect attracting boards. This solution reduces the insect attracting effect of the original insect attracting board, and the installation of the insect attracting board still requires two steps, opening the clip, putting the insect attracting board into the clip and loosening it, while the utility model only requires one step, that is, putting the insect attracting board in front of the bracket, which reduces the time required for installation or insect attracting board, and the insect attracting board bracket used in the utility model is double-sided, and there is no disadvantage of the single-sided insect attracting board of the above utility model;

[0005] For example, the utility model announcement number CN214155945U discloses a multi-layer insect attractant board. This utility model provides a multi-layer insect attractant board to solve the problem that the insect attractant board in the prior art needs to be frequently replaced. The insect attractant board is fixed by an elastic pressing sheet and can be quickly rearranged.

[0006] However, the disadvantages are the same as those of the previous utility model. Due to design problems, only one side of the insect trap can be used, and there are many steps to install and replace the insect trap, which increases the time required for replacing the insect trap, affecting the use effect of the bracket.

[0007] Another example is the utility model announcement number CN110012889B which discloses an adjustable insect trap bracket. The utility model provides an adjustable insect trap bracket, which is convenient for installing and replacing the insect trap, and can support double-sided insect trapping. The extension part can limit the free end of the insect trap grid frame between the connection between the insect trap grid frame and the cross bar and the extension part, and the insect trap grid frame is closed. When the extension part is in the second position, the insect trap grid frame is opened.

[0008] In the above document, the insect attractant plate in the middle of the grid is fixed by a horizontal bar latch. However, the method of replacing the insect attractant plate is quite cumbersome, and the grid needs to be opened to take out the latch, and the fixing method also uses iron wire, which is more cumbersome than the general insect attractant plate fixing method. The grid design is used to facilitate monitoring and reporting. Since the grid obscures a part of the insect attractant plate, it is easy to have a negative effect on the actual insect attracting effect.

[0009] In view of the above problems, it is urgent to carry out innovative design based on the original bracket structure. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Embodiment 1: This embodiment Figure 1 , Figure 3 and Figure 8 As shown, in order to solve the problem that the existing bracket is difficult to adjust to any height, the working process of the internal lifting structure of the bracket is disclosed, and the effect of the bracket being able to adjust to any height within a certain range is achieved. The specific contents are as follows:

[0040] A support rod 1 and a mounting tube 2 threadedly mounted on the outer side of the lower end of the support rod 1;

[0041] A tripod 3 is fixedly installed at the lower end of the mounting tube 2, a limited cavity 13 is provided inside the support rod 1, and a lifting rod 4 is slidably installed inside the limited cavity 13, and a fixed shaft 5 is fixedly installed on the upper end of the lifting rod 4, two groups of support plates 6 are rotatably installed on the outer side of the fixed shaft 5, and a limited shaft 7 is fixedly installed inside one end of the support plate 6 away from the fixed shaft 5, and a positioning plate 8 is rotatably installed on the outer side of the limited shaft 7, and a magnetic plate 9 is nested and installed on the outer side of the positioning plate 8;

[0042] A lifting structure is provided inside the support rod 1, and the lifting structure can achieve the effect of adjusting the height of the bracket;

[0043] A limit cavity 13 and a fixed block 14 are provided inside the lifting structure. The fixed block 14 is fixedly installed inside the limit cavity 13, and a moving rod 15 is slidably installed inside the fixed block 14. A pulling block 18 is fixedly installed at one end of the moving rod 15 away from the limit cavity 13, and the pulling block 18 is located on the outside of the support rod 1.

[0044] A seal 16 is fixedly installed on the outer side of the pulling block 18, and the seal 16 is sealed and connected to the limiting cavity 13 through a sealing ring, and the seal 16 is an isosceles trapezoidal structure in front view, and the seal 16 is located between the fixed block 14 and the pulling block 18;

[0045] A support spring 17 is sleeved on the outer side of the movement rod 15, and the support spring 17 is located between the fixed block 14 and the sealing member 16, and the two ends of the support spring 17 are in close contact with the fixed block 14 and the sealing member 16 respectively;

[0046] A placement cavity 19 and a placement piece 20 are provided inside the folding structure. The placement cavity 19 is opened inside the upper end of the support plate 6, and the placement piece 20 is slidably installed inside the placement cavity 19, and two sets of traction ropes 21 are fixedly installed on the outside of the placement piece 20, and the traction ropes 21 are located inside the support plate 6.

[0047] When using the easy-to-install magnetic bracket of the insect-attracting plate, first install the bracket at the position where work is required. During the installation process, the tripod 3 needs to be inserted into the ground, and then the height of the bracket can be adjusted. In this process, the lifting rod 4 is directly pulled to slide upward inside the support rod 1. During the upward sliding process of the lifting rod 4, the air pressure inside the limiting cavity 13 will be lower than the external air pressure. At this time, the sealing member 16 will separate from the limiting cavity 13 and allow the external air to enter the limiting cavity 13. At this time, the lifting rod 4 can continue to move upward, and the sealing member 1 6 is separated from the limiting cavity 13, the moving rod 15 will slide inside the fixing block 14, and the sealing member 16 will squeeze the supporting spring 17 and make the supporting spring 17 shrink. After the lifting rod 4 drives the supporting plate 6 to the required height, the lifting rod 4 can be stopped from being pushed. At this time, the shrinking supporting spring 17 will expand and make the sealing member 16 seal with the limiting cavity 13 again. At this time, the lifting rod 4 can be limited inside the supporting rod 1. At this point, the height adjustment process of the bracket is completed, which effectively improves the convenience of using the bracket.

[0048] Embodiment 2: This embodiment is as follows Figure 1-Figure 7 As shown, in order to solve the problem that the existing bracket is difficult to shrink and transport, the working process of the internal folding structure of the bracket is disclosed, and the bracket is reduced in space by shrinking to facilitate transportation. The specific contents are as follows:

[0049] A folding structure is provided inside the support plate 6, and the folding structure can achieve the effect of folding and storing the support plate 6 and the positioning plate 8;

[0050] A moving groove 22 is provided inside the folding structure, and the moving groove 22 is opened inside the support plate 6, and a moving part 24 is slidably installed inside the support plate 6, and a return spring 23 is fixedly installed at one end of the moving part 24 close to the placement cavity 19, and one end of the moving part 24 close to the return spring 23 is fixedly connected to the traction rope 21;

[0051] The folding structure is provided with engaging grooves 25 and limiting grooves 26 inside. Two groups of engaging grooves 25 are provided inside the fixed shaft 5, and two groups of limiting grooves 26 are provided inside the pulling block 18. The engaging grooves 25 and limiting grooves 26 are respectively engaged with the moving part 24.

[0052] In the process of carrying the magnetic bracket of the insect attracting plate that is easy to install, it is necessary to reduce the space occupied by the bracket. In this process, it is necessary to press the pulling block 18 and make the pulling block 18 approach the support rod 1. At this time, the sealing member 16 will separate from the limiting cavity 13 and the gas inside the limiting cavity 13 will be discharged under the gravity of the lifting rod 4.

[0053] Pulling the placement piece 20 upward can cause the traction rope 21 to pull the moving piece 24 to move, and the moving piece 24 will move away from the engaging groove 25 and the limiting groove 26. During this process, the return spring 23 will be squeezed by the moving piece 24 and shrink. After the engaging groove 25 and the limiting groove 26 are separated from the moving piece 24, the support plate 6 and the positioning plate 8 can be rotated. The rotation of the positioning plate 8 and the support plate 6 can further reduce the space occupied by the bracket. By reducing the space occupied by the bracket, the bracket can be easily carried.

[0054] Embodiment 3: This embodiment is as follows Figure 1-Figure 2 and Figure 6 As shown, in order to solve the problem of inconvenience in replacing the insect attracting plate 10, the process of replacing the insect attracting plate 10 at the upper end of the bracket is disclosed, and the effect of facilitating the replacement of the insect attracting plate 10 by the bracket is achieved, and the specific contents are as follows:

[0055] A magnetic plate 27 is provided on the side of the magnetic plate 9 away from the positioning plate 8, and an insect attracting plate 10 is fixedly installed on the side of the magnetic plate 27 close to the support rod 1, and an easy-tear buckle 11 is fixedly installed on the upper end of the magnetic plate 27, and an anti-sticking film 12 is bonded to the outer sides of the front and rear ends of the insect attracting plate 10;

[0056] The magnetic plate 9 and the magnetic attraction plate 27 are opposite magnetic poles, and the magnetic plate 9 is in close contact with the magnetic attraction plate 27, and two groups of magnetic attraction plates 27 are symmetrically arranged about the vertical center axis of the insect attracting plate 10;

[0057] The insect attracting board 10 is made of waterproof corrugated paper, and the anti-adhesive film 12 bonded to the outside of the insect attracting board 10 is made of PE material. The thickness of the insect attracting board 10 is 3 mm, and the insect attracting board 10 is yellow as a whole.

[0058] During the installation of the insect attracting plate 10 at the upper end of the bracket, it is necessary to make the magnetic suction plates 27 on both sides of the insect attracting plate 10 engage with the two groups of magnetic plates 9, and then the two groups of anti-adhesion films 12 on the outer side of the insect attracting plate 10 can be torn off, and then the two sides of the insect attracting plate 10 can be made to stick to the pests. After the insect attracting plate 10 has been used for a period of time, it needs to be replaced. In this process, the insect attracting plate 10 is directly removed from the upper end of the support plate 6 through the easy tear buckle 11, and the magnetic suction plate 27 is separated from the magnetic plate 9, and then the installation of the insect attracting plate 10 can be completed by the attraction of the magnetic suction plate 27 and the magnetic plate 9 again, thereby effectively improving the convenience of replacing the insect attracting plate 10;

[0059] The edge of the insect attractant board 10 has an embedded or exposed ferromagnetic part, so that it can be directly placed in front of a magnetic bracket and fixed without the need for wire or splints. The insect attractant board 10 is a traditional three-layer structure, the middle layer is the insect attractant board 10, and the front and back are anti-sticking films 12. Ferromagnetism can be achieved by embedding iron wire, iron sheet or iron powder in the interlayer. The key point is that the ferromagnetism is set on the left and right but not on the top and bottom, which is also convenient for maximizing the use of the sticky part of the insect attractant board 10. It is also convenient for rolling production of insect attractant boards, and can be cut after mass production, which increases the overall practicality.

[0060] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
