Description

Technical Field

[0001] This utility model relates to the field of bird feeder technology, and in particular to a squirrel-proof bird feeder. Background Technology

[0002] With the improvement of living standards, people have adopted bird feeders for bird watching. Bird feeders are devices placed in outdoor environments such as parks and forests to provide food for wild birds. They are generally installed on the ground or hung on tree branches or supports. In existing bird feeders, the inner tube for holding the food is a one-piece structure, while the outer cover covers the outside of the inner tube. When squirrels climb on it, the outer cover closes the window to prevent them from eating. However, the overall height of the outer cover covering the inner tube requires a large amount of sheet metal and metal. The existing technology of the outer cover covering the inner tube has obvious defects in terms of material saving and cost control. There is an urgent need for an improved solution that can reduce material consumption, simplify the structure, and still have the function of preventing squirrels from eating.

[0003] Therefore, it is necessary to provide a squirrel-proof bird feeder to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a bird feeder to prevent squirrels from flying, which solves the problem of excessive material usage in the existing bird feeder's outer casing covering the inner tube in terms of material saving and cost control.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a squirrel-proof bird feeder, comprising a base and a fixed tube fixed on the top of the base for storing food, the base comprising an inner cylinder connected to the fixed tube, a sleeve that can be raised and lowered on the inner cylinder, and an elastic element located on the periphery of the inner cylinder for resetting the sleeve, the periphery of the inner cylinder is provided with a recessed placement groove for the elastic element to fit, the sleeve abuts against the upper part of the elastic element, the lower part of the inner cylinder is provided with a plurality of first windows for birds to feed, the lower part of the sleeve is provided with a plurality of second windows adapted to the first windows and a standing pole located below the second windows and extending away from the second windows.

[0006] In this utility model, the inner cylinder includes an L-shaped first limiting ring, an L-shaped second limiting ring, an inner tube located between the first limiting ring and the second limiting ring, and a fixing seat located at the bottom of the inner tube. The diameters of the first limiting ring and the second limiting ring are both larger than the diameter of the inner tube. The elastic element is sleeved on the inner tube, and the second limiting ring and the sleeve abut against the two ends of the elastic element respectively. The first window is located on the fixing seat.

[0007] In this invention, an annular limiting plate is provided on the inner side of the top of the sleeve, the limiting plate is located below the first limiting ring, and the elastic element abuts against the limiting plate.

[0008] In this invention, the second limiting ring is provided with a plurality of protrusions evenly distributed around its periphery, and the inner wall of the sleeve is provided with a plurality of symmetrical limiting strips extending along the height direction of the sleeve, with the symmetrical limiting strips located on both sides of the protrusions.

[0009] In this invention, the second limiting ring has multiple protrusions on its periphery, and the sleeve has multiple strip holes extending along the height direction of the sleeve. The protrusions are located in the strip holes and are used to limit the rotation of the sleeve.

[0010] In this invention, a funnel for grain leakage is also provided on the inner side of the fixed base.

[0011] In this invention, the bottom of the fixing base is provided with multiple through holes.

[0012] In this invention, the top of the fixed tube is also provided with a detachable cap that is connected to the fixed tube, and the cap is conical.

[0013] In this invention, a hook is provided inside the cap, and one end of the hook extends to the top of the cap.

[0014] In this invention, the fixing tube is made of a transparent material.

[0015] Compared with the prior art, the advantages of this utility model are as follows: When a squirrel stands on the pole to feed, the pole causes the sleeve to move downward. The sleeve squeezes the elastic element, causing the second window to misalign with the first window and the side wall of the sleeve to close the first window, preventing the squirrel from feeding through the first window. Since the sleeve only moves up and down on the inner cylinder, less material is needed, thus reducing the material used in the sleeve and effectively saving costs. While saving costs, it can also effectively prevent squirrels from feeding. Attached Figure Description

[0033] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0034] This utility model provides a squirrel-proof bird feeder, including a base 12 and a fixing tube 11 fixed to the top of the base 12 for storing food. The base 12 includes an inner cylinder 121 connected to the fixing tube 11, a sleeve 122 that can be raised and lowered on the inner cylinder 121, and an elastic member 123 located on the periphery of the inner cylinder 121 for resetting the sleeve 122. The periphery of the inner cylinder 121 is provided with a recessed placement groove for the elastic member 123 to fit. The sleeve 122 abuts against the upper part of the elastic member 123. The lower part of the inner cylinder 121 is provided with multiple first windows for birds to feed. 1218, the lower part of the sleeve 122 is provided with multiple second windows 1221 adapted to the first window 1218, and a standing pole 1222 located below the second windows 1221 and extending away from the second windows 1221. The fixing tube 11 is used to store food to extend the time for adding food. The base 12 is used for birds to eat. The elastic force of the elastic element 123 is greater than the weight of the bird and less than the weight of the squirrel. When the sleeve 122 is in the initial state, the second windows 1221 of the sleeve 122 overlap with the first windows 1218 of the inner cylinder 121, which facilitates... When birds come to feed, they stand on the stand 1222. Because of their light weight, they cannot move the sleeve 122, allowing them to pass their beaks through the second window 1221 into the first window 1218 to eat. When squirrels come to feed, their heavier weight allows them to climb onto the stand 1222, causing the sleeve 122 to move downwards. As the sleeve 122 moves downwards, it compresses the elastic element 123, causing it to deform. This deformation causes the second window 1221 and the first window 1218 to move downwards. The window 1218 is misaligned so that the side wall of the sleeve 122 closes the first window 1218, preventing squirrels from eating through the first window 1218. When the squirrel leaves the bird feeder, the elastic element 123, according to its own spring, drives the sleeve 122 to restore its deformation, so that the second window 1221 of the sleeve 122 overlaps with the first window 1218, making it easier for birds to eat again. Since the sleeve 122 is connected to the inner tube 1213, less material is needed, thereby reducing the material used for the sleeve 122 and saving costs. While saving costs, it can also effectively prevent squirrels from eating.

[0035] In this embodiment, the elastic element 123 is a spring, but it is not limited to using only springs; it can also be a sheet spring, etc.

[0036] Please refer to Figure 3 , Figure 3This is a perspective view of the inner cylinder of the anti-squirrel bird feeder of this utility model. The inner cylinder 121 includes an L-shaped first limiting ring 1211, an L-shaped second limiting ring 1212, an inner tube 1213 located between the first limiting ring 1211 and the second limiting ring 1212, and a fixing seat 1214 located at the bottom of the inner tube 1213. The diameters of the first limiting ring 1211 and the second limiting ring 1212 are both larger than the diameter of the inner tube 1213. An elastic element 123 is sleeved on the inner tube 1213. The second limiting ring 1212 and the sleeve 122 respectively abut against the two ends of the elastic element 123. A first window 1218 is located on the fixing seat 1214. The elastic element 123 is sleeved on the inner tube 121. After the first limiting ring 1211 and the second limiting ring 1212 are used to limit the elastic element 123 to prevent the elastic element 123 from separating from the inner tube 1213. At the same time, the sleeve 122 abuts against the elastic element 123. When a squirrel is on the perch 1222, the sleeve 122 moves down and squeezes the elastic element 123, causing the elastic element 123 to deform so that the side wall of the sleeve 122 closes the first window 1218. When the squirrel leaves the perch 1222, the elastic element 123 loses the squeezing force of the sleeve 122 and squeezes the sleeve 122 in the opposite direction, so that the sleeve 122 is reset and the second window 1221 of the sleeve 122 overlaps with the first window 1218, making it easier for birds to eat.

[0037] Please refer to Figure 4 , Figure 4 The three-dimensional design of the sleeve for the anti-squirrel and bird feeder of this utility model Figure 1 An annular limiting plate 1224 is provided on the inner side of the top of the sleeve 122. The limiting plate 1224 is located below the first limiting ring 1211. The elastic element 123 abuts against the limiting plate 1224. The limiting plate 1224 is located between the elastic element 123 and the first limiting ring 1211. One end of the elastic element 123 is located below the limiting plate 1224. The first limiting ring 1211 is used to limit the limiting plate 1224 and prevent the limiting plate 1224 from separating from the first limiting ring 1211, so that the elastic element 123 is stably sleeved on the inner tube 1213. When the sleeve 122 moves down, the limiting plate 1224 squeezes the elastic element 123, so that the limiting plate 1224 can stably apply pressure to the elastic element 123. When the elastic element 123 squeezes the limiting plate 1224 in the opposite direction, the sleeve 122 can stably rise.

[0038] The second limiting ring 1212 has a plurality of protrusions 1216 evenly arranged around its periphery. The inner wall of the sleeve 122 has a plurality of symmetrical limiting strips 1223 extending along the height direction of the sleeve 122. The symmetrical limiting strips 1223 are located on both sides of the protrusions 1216 and are fixed inside the sleeve 122 to prevent the sleeve 122 from rotating, so that the second window 1221 of the sleeve 122 can overlap with the first window 1218 of the inner cylinder 121.

[0039] Please refer to Figure 5 , Figure 5 The three-dimensional design of the sleeve for the anti-squirrel and bird feeder of this utility model Figure 2 The second limiting ring 1212 has multiple protrusions 1216 on its periphery, and the sleeve 122 has multiple strip holes 1225 extending along the height direction of the sleeve 122. The protrusions 1216 are located in the strip holes 1225 to limit the rotation of the sleeve 122. The protrusions 1216 are used to prevent the sleeve 122 from rotating and to avoid the second window 1221 of the sleeve 122 from being offset from the first window 1218. At the same time, when the sleeve 122 moves, the protrusions 1216 are also used to limit the position of the sleeve 122. When the sleeve 122 rises, the second window 1221 of the sleeve 122 can accurately overlap with the first window 1218.

[0040] The inner side of the fixing base 1214 is also provided with a grain leakage funnel 1215, which is used to reduce the grain discharge speed and avoid grain waste.

[0041] The bottom of the mounting base 1214 is provided with multiple through holes 1217. The through holes 1217 are used for water leakage. When birds put their heads into the mounting base 1214 while eating, the raindrops carried by their heads fall into the mounting base 1214. The through holes 1217 are used to drain the water in the mounting base 1214 to prevent the food from getting damp and moldy.

[0042] The top of the fixed tube 11 is also provided with a cap 13 that is detachably connected to the fixed tube 11. The cap 13 is conical and is used to close the fixed tube 11 to prevent the grain inside the fixed tube 11 from being exposed to the air. At the same time, it is used to prevent rainwater from falling into the fixed tube 11 when it rains. Also, the cap 13 is detachably connected to the fixed tube 11 to facilitate adding grain into the fixed tube 11.

[0043] The cap 13 is provided with a hook 14, one end of which extends to the top of the cap 13. The hook 14 is used to conveniently hang the bird feeder on a tree branch or a support. Hanging it on a tree or a support makes it easier for birds to find and increases their sense of security.

[0044] The fixing tube 11 is made of transparent material, which makes it easier for birds to find the food inside the fixing tube 11, and is used to attract birds to come and eat.

[0045] In this embodiment, the standing pole 1222 is L-shaped. On the one hand, it is convenient to fix the standing pole 1222 on the sleeve 122, and on the other hand, it is convenient for birds to stand and eat.

[0046] Working principle: When the sleeve 122 is in its initial position, the second window 1221 of the sleeve 122 overlaps with the first window 1218 of the fixing seat 1214. When birds come to feed, they stand on the perch 1222. Due to the light weight of the birds, the pressure of the sleeve 122 is insufficient to compress the elastic element 123, thus keeping the sleeve 122 in its initial position. This allows the birds to easily pass their heads through the second window 1221 into the first window 1218 to feed. If a squirrel comes to feed, when the squirrel climbs onto the perch 1222, its weight... The heavier pole 1222 causes the sleeve 122 to move downwards. As the sleeve 122 moves downwards, it compresses the elastic element 123, causing the elastic element 123 to deform. When the sleeve 122 moves downwards, the protrusion 1216 limits the movement of the limiting strip 1223, preventing the sleeve 122 from rotating during movement. Similarly, if the protrusion is located inside the slotted hole of the sleeve, the protrusion 1216 limits the movement trajectory of the sleeve 122 through the slotted hole 1225 during movement, preventing the sleeve 122 from rotating during movement. As the squirrel rotates, the second window 1221 of the sleeve 122 moves downward, causing it to misalign with the first window 1218. The side wall of the sleeve 122 blocks the first window 1218, preventing the squirrel from eating through it. After the squirrel leaves, the elastic element 123 loses the squirrel's pressure from the sleeve 122. The elastic element 123 then reverses the pressure on the sleeve 122, causing it to return to its original position. This allows the second window 1221 of the sleeve 122 to overlap with the first window 1218 of the fixing seat 1214, facilitating the bird's return. When feeding, the protrusion 1216 limits the limiting strip 1223, preventing the sleeve 122 from rotating during the downward or upward movement of the sleeve 122, so that the second window 1221 of the sleeve 122 can always overlap with the first window 1218 when the sleeve 122 is reset. Since the sleeve 122 is installed on the periphery of the inner cylinder 121 and the inner cylinder 121 is located below the fixed tube 11, less material is required, which reduces the material used for the sleeve 122 and saves costs. At the same time, it can effectively prevent squirrels from feeding.

[0047] In this preferred embodiment, the anti-squirrel bird feeder works by having a squirrel stand on the pole to feed. The pole causes the sleeve to move downward, and the sleeve compresses the elastic element, causing the second window to misalign with the first window. This also causes the side wall of the sleeve to close the first window, preventing the squirrel from feeding through the first window. Since the sleeve only moves up and down on the inner cylinder, less material is needed, thus reducing the material used in the sleeve and effectively saving costs. While saving costs, it can also effectively prevent squirrels from feeding.

[0048] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
