The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] In order to enable those skilled in the technical field to better understand the solution of the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 4 , the present application provides a hanging rack 100, the hanging rack 100 includes a first mounting portion 10 and a second mounting portion 20 opposite to the first mounting portion 10, and a tray 30 connected to the first mounting portion 10 and the second mounting portion 20. The first mounting portion 10 is used to hang on a supporting object 01, and the second mounting portion 20 is used to mount an electronic device 02. The tray 30 receives the bottoms of the first mounting portion 10 and the second mounting portion 20, and the tray 30 is used to accommodate a viscous substance, and the viscous substance prevents small organisms from climbing from the first mounting portion 10 to the second mounting portion 20.

[0024] It can be understood that the hanging rack 100 is mainly used to mount the electronic device 02 on a supporting object 01 such as a tree, and the supporting object 01 can also be a utility pole or a street lamp pole. The electronic device 02 can be a device for bird conservation, or a device for assisting in bird conservation, or a device for conserving other animals with a habit of living at high altitudes.

[0025] Since the electronic device 02 is fixed to the support object 01 via the mounting bracket 100, and the support object 01 is in an outdoor environment, there may be small creatures such as small ants crawling onto the mounting bracket 100 and then from the mounting bracket 100 to the electronic device 02, which may affect the normal use of the electronic device 02. For example, small ants may cause a short circuit in the circuit of the electronic device 02, thus damaging the electronic device 02.

[0026] In the mounting bracket 100 of this embodiment, the first mounting portion 10 is fixed to the support object 01, the second mounting portion 20 mounts the electronic device 02, the bottom of the first mounting portion 10 and the bottom of the second mounting portion 20 are received by the tray 30, and the tray 30 is used to accommodate a viscous substance, and the viscous substance prevents small creatures from crawling from the first mounting portion 10 to the second mounting portion 20, thereby preventing small creatures from crawling to the electronic device 02 and ensuring the normal use of the electronic device 02.

[0027] In this embodiment, one end of the first mounting portion 10 away from the tray 30 is used to be fixed to the support object 01. One end of the second mounting portion 20 away from the tray 30 is used to mount the electronic device 02. Since the first mounting portion 10 and the second mounting portion 20 are relatively fixed, the electronic device 02 can be stably fixed to the support object 01. For example, the electronic device 02 as a bird care device can be stably fixed to a high position on the tree trunk via the mounting bracket 100. When the mounting bracket 100 fixes the electronic device 02 to the support object 01, the opening of the tray 30 faces vertically upward to effectively store the viscous substance in the tray 30 and prevent the viscous substance from falling off. Since the bottom of the first mounting portion 10 is received in the tray 30 and the bottom of the second mounting portion 20 is received in the tray 30, the path of small creatures from the first mounting portion 10 to the second mounting portion 20 must pass through the inside of the tray 30, that is, it will pass through the viscous substance inside the tray 30. The viscous substance in the tray 30 surrounds the bottom of the first mounting portion 10 and the bottom of the second mounting portion 20, so that the viscous substance can prevent small creatures from crawling from the first mounting portion 10 to the second mounting portion 20. For example, when a small creature crawls from the support object 01 to the first mounting portion 10 and then to the bottom of the first mounting portion 10, if it continues to crawl, it will contact the viscous substance, and the adhesive force of the viscous substance will cause the small creature to be unable to continue crawling, thus achieving the prevention of small creatures from crawling from the support object 01 to the electronic device 02. The viscous substance can be water, or glue, or adhesive and other substances.

[0028] Further, the mounting bracket 100 further includes a U-shaped bending portion 40 integrated with the first mounting portion 10 and the second mounting portion 20, and the U-shaped bending portion 40 is received in the tray 30.

[0029] In this embodiment, the first mounting portion 10, the U-shaped bending portion 40, and the second mounting portion 20 integrally form a bent metal part. Specifically, the first mounting portion 10 is substantially a rectangular plate member, and the second mounting portion 20 is substantially a rectangular plate member. The U-shaped bending portion 40 is a "U"-shaped plate member. The U-shaped bending portion 40 is fixed to the tray 30 to ensure the stability of the metal part and the tray 30. The first mounting portion 10, the second mounting portion 20, and the U-shaped bending portion 40 are integrated, which is convenient for manufacturing and has high strength, enhancing the stability between the first mounting portion 10 and the supporting object 01, and enhancing the load-bearing capacity of the second mounting portion 20. Since the U-shaped bending portion 40 is connected to the first mounting portion 10 and the second mounting portion 20, the supporting force of the second mounting portion 20 can be transmitted to the first mounting portion 10 through the U-shaped bending portion 40. Furthermore, the tray 30 will not bear excessive stress, preventing the tray 30 from tilting, and thus ensuring that the viscous substance in the tray 30 will not overflow. At least a part of the U-shaped bending portion 40 is covered by the viscous substance, thereby blocking the path from the first mounting portion 10 to the second mounting portion 20, and effectively preventing small organisms from crawling from the first mounting portion 10 to the second mounting portion 20.

[0030] Furthermore, two opposite buckles 31 are provided in the tray 30, and the two buckles 31 are engaged with opposite sides of the U-shaped bending portion 40.

[0031] In this embodiment, the buckle 31 protrudes from the bottom of the tray 30. The ends of the buckle 31 are bent towards each other. When the two buckles 31 are engaged with the U-shaped bending portion 40, the ends of the buckle 31 can be pressed against the edge of the U-shaped bending portion 40, and force the U-shaped bending portion 40 to abut against the bottom of the tray 30, so that the U-shaped bending portion 40 and the tray 30 are stable, and the tray 30 is not easily detached from the U-shaped bending portion 40, increasing the reliability of the hanger 100. The buckle 31 is made of an elastically deformable material, which is convenient for quickly assembling the U-shaped bending portion 40 and the tray 30. It can be understood that the viscous substance can cover the buckle 31, increasing the length of the path blocking the crawling of small organisms between the first mounting portion 10 and the second mounting portion 20, and improving the reliability of blocking the crawling of small organisms.

[0032] In this embodiment, the U-shaped bending portion 40 is provided with concave engaging shoulders 41 on two opposite edges. The engaging shoulders 41 cooperate with the buckles 31, so that the buckles 31 press the engaging shoulders 41 to ensure the effective positioning of the buckles 31 on the U-shaped bending portion 40.

[0033] Furthermore, two opposite limiting plates 32 are provided in the tray 30. The two limiting plates 32 limit opposite sides of the U-shaped bending portion 40, and the buckles 31 extend from the tops of the limiting plates 32.

[0034] In this embodiment, the limiting plate 32 extends from the bottom of the tray 30 towards the opening of the tray 30. The limiting plate 32 fits against the edge of the U-shaped bending portion to effectively limit the U-shaped bending portion 40 and prevent the U-shaped bending portion 40 from moving left and right within the tray 30. The buckle 31 extends from the edge of the limiting plate 32 away from the bottom of the tray 30, thereby increasing the height of the buckle 31 to allow a U-shaped bending portion 40 with sufficient thickness to be accommodated within the tray 30, thus increasing the structural strength of the U-shaped bending portion 40 and improving the mounting performance of the hanger 100. It can be understood that a plurality of buckles 31 can also be arranged at intervals along the edge of each limiting plate 32 to improve the stability between the tray 30 and the U-shaped bending portion 40.

[0035] In this embodiment, the length of the limiting plate 32 extends from the side wall of the tray 30 near the first mounting portion 10 to the side wall of the tray 30 near the second mounting portion 20. Thus, the limiting plate 32 can form a reinforcing rib of the tray 30 in the direction from the first mounting portion 10 to the second mounting portion 20, improving the structural strength of the tray 30. There is a certain distance between the side of the limiting plate 32 facing away from the U-shaped bending portion 40 and the inner wall of the tray 30, so that there is a distance between the opposite two edges of the U-shaped bending portion 40 and the two inner side walls of the tray 30, enabling viscous substances to bend and block the U-shaped bending portion 40, improving the reliability of blocking the crawling of small organisms.

[0036] Furthermore, the tray 30 is provided with two opposite reinforcing ribs 33, and the reinforcing ribs 33 extend from the inner side wall of the tray 30 to the limiting plate 32.

[0037] In this embodiment, the reinforcing rib 33 extends from the bottom of the tray 30, and one end of the reinforcing rib 33 is connected to the inner wall of the tray 30, and the other end is connected to the limiting plate 32. The height of the end of the reinforcing rib 33 connected to the inner wall of the tray 30 is greater than the height of the end of the reinforcing rib 33 connected to the limiting plate 32, thereby increasing the stress intensity of the limiting plate 32 and preventing the limiting plate 32 from breaking under stress. Arc-shaped inner chamfers are provided on the bottom and the surrounding side walls of the tray 30. To ensure uniform wall thickness of the tray 30, corresponding arc-shaped outer chamfers are provided on the outer surface around the bottom of the tray 30, which can enhance the appearance simplicity performance of the tray 30, facilitating the sufficient concentration of viscous substances to "block" the U-shaped bending portion 40 and reducing the use cost. And because arc-shaped chamfers are provided inside the tray, it is convenient to increase the smoothness of the inner wall of the tray 30, thereby preventing small organisms from crawling on the inner wall of the tray. When there are small organisms on the inner wall of the tray, they will fall onto the viscous substances inside the tray due to the smoothness of the inner wall.

[0038] Further, two opposite limiting posts 34 are provided on the inner wall of the tray 30 adjacent to the first mounting portion 10, and a limiting boss 35 is provided between the two limiting posts 34. The first mounting portion 10 is provided with limiting holes 11 respectively cooperating with the two limiting posts 34, and a limiting groove 12 cooperating with the limiting boss 35.

[0039] In this embodiment, the limiting posts 34 protrude horizontally from the inner wall of the tray 30. The two limiting posts 34 can be pins provided on the tray 30, or can be integrally formed with the tray 30 as metal inserts. Specifically, the tray 30 is a plastic part. The inner wall of the tray 30 is provided with a draft angle to facilitate the molding and demolding of the tray 30. To enhance the structural stability between the limiting posts 34 and the tray 30, a locally thickened inner wall 36 is provided at the position of the tray 30 corresponding to the limiting posts 34, and the limiting posts 34 protrude from the locally thickened inner wall 36, so that the structural reliability of the limiting posts 34 is enhanced. When the mating hole of the first mounting portion 10 cooperates with the limiting posts 34, the first mounting portion 10 and the locally thickened inner wall 36 can be closely attached, so as to prevent the first mounting portion 10 from moving back and forth in the tray 30. The limiting boss 35 and the limiting posts 34 are at approximately the same height inside the tray 30. The limiting boss 35 is provided with an inclined surface facing away from the bottom of the tray 30. When the first mounting portion 10 is snapped into the tray 30, the bottom of the first mounting portion 10 can be guided along the inclined surface, so that the limiting boss 35 can be easily snapped into the limiting groove 12, thereby effectively positioning the first mounting portion 10 and the tray 30 and preventing the first mounting portion 10 from moving relative to the tray 30.

[0040] In this embodiment, the side plate of the tray 30 adjacent to the first mounting portion 10 is higher than the side plate of the tray 30 adjacent to the second mounting portion 20, so as to ensure effective support of the first mounting portion 10 by the tray 30 and enhance the structural reliability between the tray 30 and the first mounting portion 10. The limiting posts 34 and the limiting boss 35 are provided on the higher part of the tray 30. Of course, in other embodiments, the side plate of the tray 30 connecting the second mounting portion 20 can also be provided with a certain higher part to enhance the stability between the tray 30 and the second mounting portion 20. Since the side plate of the tray 30 adjacent to the first mounting portion 10 serves as a fulcrum to mainly support the force of the entire hanger 100, the higher side plate of the tray 30 adjacent to the first mounting portion 10 can enhance the load-bearing capacity of the entire hanger 100.

[0041] Further, the first mounting portion 10 is provided with screw holes 13 for cooperating with screws to fix the first mounting portion 10 to the support object 01.

[0042] In this embodiment, the first mounting portion 10 is provided with two screw holes 13, and the two screw holes 13 are arranged along the width direction of the first mounting portion 10, so as to keep the bottom of the tray 30 stable in the horizontal direction, thereby preventing the leakage of the viscous substances in the tray 30. Of course, in other embodiments, three or more screw holes 13 may also be provided on the first mounting portion 10.

[0043] In this embodiment, the two edges of the first mounting portion 10 in the width direction are provided with first flanges 14 bent away from the second mounting portion 20. The first flanges 14 protrude relative to the outer side wall of the tray 30 to enhance the structural strength of the first mounting portion 10. When the first mounting portion 10 is fixed to the support object 01, the first flanges 14 abut against the support object 01, and there is a certain distance between the tray 30 and the support object 01. Furthermore, small organisms will not directly crawl from the support object 01 to the outer wall of the tray 30, thereby preventing small organisms from crawling from the tray 30 to the electronic device 02 on the second mounting portion 20. The end of the first flange 14 also has a certain distance from the opening of the tray 30 to prevent small organisms from crawling to the opening of the tray 30.

[0044] Furthermore, the first mounting portion 10 is provided with a hollow groove 15, and a clamping plate 16 extends from the end of the hollow groove 15 away from the tray 30, and the clamping plate 16 is used to cooperate with a hoop or a binding rope on the support object 01.

[0045] In this embodiment, the hollow groove 15 penetrates through the first mounting portion 10 so that the clamping plate 16 protrudes outward, and there is a hollow area between the clamping plate 16 and the hollow groove 15. Furthermore, a hoop or a binding rope can pass through the hollow area between the clamping plate 16 and the hollow groove 15. The hoop or the binding rope can bind the first mounting portion 10 to the support object 01, and the end of the clamping plate 16 limits the hoop or the binding rope to prevent the first mounting portion 10 from detaching from the hoop or the binding rope.

[0046] In this embodiment, the hollow groove 15 communicates with the two screw holes 13. The hollow groove 15 is a square groove. The two screw holes 13 are respectively located at two corners of the hollow groove 15. The first mounting portion 10 can be fixed to the support object 01 by adapting screws to the screw holes 13, and can also be fixed to the support object 01 by adapting a hoop or a binding rope to the clamping plate 16, so that the first mounting portion 10 has a variety of stable ways to be fixed to the support object 01, which is convenient for quickly installing the first mounting portion 10 and supports a variety of installation methods.

[0047] In another embodiment, as Figure 3 shown, and Figure 2The implementation manners are substantially the same. The difference is that the first mounting portion 10 is provided with two hollow slots 15, the two hollow slots 15 are respectively communicated with the two screw holes 13, and the clamping plate 16 is formed between the two hollow slots 15. The hollow slot 15 has a hollow hole 151 extending to the first folded edge 14. The two hollow holes 151 are used to allow a hoop, or a bandage, or a binding rope to pass through, so as to fix the first mounting portion 10 on the support 01.

[0048] Further, please continue to refer to Figure 2 、 Figure 3 and Figure 4 , the second mounting portion 20 is provided with two opposite hooks 21, the hooks 21 extend in a direction away from the tray 30, and the hooks 21 are used for hooking with the bracket 03 of the electronic device 02.

[0049] In this embodiment, the second mounting portion 20 is provided with second folded edges 22 on both opposite sides in the width direction, and the second folded edges 22 are bent away from the first mounting portion 10. The hooks 21 are arranged on the second folded edges 22. The second mounting portion 20 and the first mounting portion 10 are an integral sheet metal part, and the first mounting portion 10 and the second mounting portion 20 can be formed by punching. The root of the hook 21 is closer to the tray 30 than the end, so that the hook 21 can support the electronic device 02 upward or fix the bracket 03 of the electronic device 02. The second folded edge 22 can enhance the structural strength of the second mounting portion 20. The bracket 03 fixed on the hook 21 can protrude relative to the tray, so that there is a certain distance between the electronic device 02 fixed on the bracket 03 and the tray 30, so as to prevent small organisms from crawling from the tray 30 to the electronic device 02.

[0050] It can be understood that by hanging the bracket 03 on the electronic device 02 on the two buckles 31, the electronic device 02 can be stably fixed on the second mounting portion 20. The electronic device 02 can be quickly disassembled from the second mounting portion 20, so as to facilitate the maintenance of the electronic device 02.

[0051] In this embodiment, the second mounting portion 20 is further provided with fixing holes 23, and the fixing holes 23 can fix the electronic device 02 through screws, or pins, or buckles 31, so as to facilitate fixing the electronic device 02 in a variety of ways.

[0052] In this embodiment, in order to enhance the structural strength of the first mounting portion 10 and the second mounting portion 20, both the first mounting portion 10 and the second mounting portion 20 are provided with strength ribs 101 extending vertically, and the strength ribs 101 can be formed by a stamping process. The number of the strength ribs 101 is not limited. By arranging the strength ribs 101 on the first mounting portion 10 and the second mounting portion 20, the first mounting portion 10 and the second mounting portion 20 can be prevented from bending and deforming, and the load-bearing capacity of the hanger 100 can be increased.

[0053] The hanger 100 provided by the embodiment of the present application houses the bottom of the first mounting portion 10 and the bottom of the second mounting portion 20 through the tray 30, and the tray 30 is used to accommodate viscous substances, which prevent small organisms from climbing from the first mounting portion 10 to the second mounting portion 20, thereby preventing small organisms from climbing to the electronic device 02 and ensuring the normal use of the electronic device 02.

[0054] The above are the preferred embodiments of the application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the application, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the application.
