Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, specifically relating to a storage device that is easy to open and protected from pets. Background Technology

[0002] In modern society, pets are a source of emotional support for many people, and more and more people are keeping pets. During the process of raising pets, they inevitably develop some bad habits, such as rummaging through things or stealing food. This behavior can cause the living space to become dirty and messy or make it impossible to control the pet's diet.

[0003] To address the aforementioned issues, containers with locking mechanisms have emerged to prevent pets from accessing the pets. These containers allow owners to store food or other items they don't want their pets to rummage through. For example, patent document CN208657629U discloses an automatic pet feeder, which includes a lid, a feed hopper, a base, and a feed bowl. The top of the feed hopper is hinged to the lid, which has a lock. The top of the feed hopper has a corresponding push-button lock that engages with the lock. The bottom of the feed hopper has a base with a motor inside. A rotating shaft is located in the center of the bottom of the feed hopper, and the motor's output shaft is connected to the rotating shaft. Multiple stirring blades are mounted on the rotating shaft at the bottom of the feed hopper. The bottom of the feed hopper also has an inclined discharge hopper, and a feed bowl is located on one side of the base below the outlet of the inclined discharge hopper.

[0004] The aforementioned existing technology can conveniently control and record the pet's eating status through structural design. The lid and body of the bucket are connected by a push-button lock, and the lid can be opened by pressing it. However, the action of pressing the lid is very intuitive and easy to learn. Pets with a certain level of intelligence (such as cats and dogs) can learn by observation and then open the lid to eat on their own.

[0005] Based on the above analysis, the present invention aims to provide a storage device that is easy for owners to open but difficult for pets to learn to open. Summary of the Invention

[0006] In view of the problems in the related technologies, this utility model proposes a storage device that is easy to open and pet-proof, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A convenient, pet-proof storage device includes a container lid and a container with a container opening. A hinge structure is provided between the container lid and the container. The container lid can be flipped relative to the container to cover or expose the container opening. The container has at least one locking position at a position away from the hinge structure, and the locking position extends along the opening direction of the container opening and protrudes beyond the edge of the container opening.

[0009] The inner side of the container lid is provided with at least one push button, the push button has a locking protrusion adapted to the locking position, the end face of the push button near the hinge structure is provided as a push end, and the push button can slide in a direction away from or near the locking position.

[0010] The top surface of the container lid is recessed downward to form a groove, and the groove side away from the hinge structure has a first opening for exposing the push end; preferably, the push end is recessed in the direction away from the hinge structure to facilitate finger gripping.

[0011] The storage device also includes at least one elastic element, one end of which is connected to the container lid and the other end of which is connected to the push buckle. The elastic element has a tendency to pull the locking protrusion close to the locking position.

[0012] Applying force causes the locking protrusion of the push-button to move away from the locking position, compressing the elastic element, unlocking the container lid, and allowing the container lid to be flipped up and opened;

[0013] When the container lid is flipped down close to the container opening, force is applied again to move the locking protrusion of the push-button away from the locking position. The locking protrusion enters the locking position, and the force is stopped. The elastic element extends and pulls the locking protrusion close to the locking position, thereby locking the container lid. The container lid cannot be flipped open.

[0014] To make it easier for the keeper to close the lid, preferably, the lock is a forward-opening hook groove structure, the lock protrudes backward and has a guide slope at the bottom, and the rotation trajectory of the lock and the guide slope coincides.

[0015] When the container lid is flipped down close to the container opening and no external force is applied to the push button, the guide slope contacts the top of the lock position and slides downward. The locking protrusion moves away from the lock position, and the elastic element is compressed until the guide slope completely slides past the top of the lock position. The locking protrusion enters the lock position, and the elastic element automatically releases and extends to pull the locking protrusion close to the lock position, locking the container lid. The breeder only needs to press the container lid to close the lid.

[0016] Preferably, the container lid has a three-dimensional structure and at least the position near the lock is a cavity structure, which is designated as the inner cavity;

[0017] The inner cavity houses the push-button and elastic element. The first opening communicates with the inner cavity, and the bottom of the inner cavity has a second opening for the lock to enter. This design avoids exposing small parts such as the push-button and elastic element, resulting in a simpler overall shape for the container lid and also preventing the accumulation of dirt and grime and impact damage.

[0018] More preferably, the first opening is no more than 10 centimeters away from the outer circumference of the container lid, so that the thumb can grasp the front end of the container lid and cooperate with other fingers gripping the push end to flip the container lid.

[0019] The elastic element can be a sheet, spring, torsion spring, or retractable rubber block. Preferably, the elastic element is a spring, which facilitates control and adjustment of the extension and retraction trajectory. The bottom of the inner cavity protrudes upward to form a column corresponding to the number of elastic elements. The outer circumference of the column protrudes away from the locking position to form a stop portion that can secure the first end of the spring. The push buckle is provided with a support portion for the second end of the spring to abut.

[0020] The spring pushes the push-button towards the hinge structure, and the compressible length of the spring after installation is greater than the front and rear thickness of the locking protrusion.

[0021] More preferably, the bottom of the push button has a mounting groove adapted to the spring, the post is located in the mounting groove away from the hinge structure, the groove wall of the mounting groove near the hinge structure serves as the top holding part, and the size of the mounting groove makes the built-in spring unable to bend.

[0022] The distance between the blocking part and the supporting part is less than or equal to the axial length of the spring when it is fully extended, but greater than the length of the spring when it is fully compressed, in order to support the push-button spring-back locking function.

[0023] Preferably, the mounting groove has a vertically extending strip groove arranged horizontally. The top surface of the column has a downward-facing fixing hole. A fixing member passes through the strip groove from top to bottom. The lower part of the fixing member is fixed to the fixing hole, and the upper part is locked to the top surface of the strip groove. The push buckle slides horizontally to lock or unlock. Compared with pushing downwards, the horizontal pushing operation can further increase the difficulty of opening the cover, making it difficult for the pet's forelimbs to bend and push the push buckle forward.

[0024] More preferably, the bottom of the inner cavity is provided with at least two upwardly protruding latches, which are opposite each other and slide to secure the push buckle. The push buckle can be pre-installed by pressing and engaging before the above-mentioned fasteners are installed. At the same time, the horizontal movement of the push buckle is further limited to ensure accurate and quick unlocking or locking.

[0025] Preferably, the bottom surface of the container lid is provided with an upwardly recessed spoon position, the spoon position is provided with a grain spoon, and the grain spoon and the container lid are provided with one or more of the following: a matching snap-fit ​​structure, a magnetic structure, and a detachable adhesive structure.

[0026] The depth of the recess at the handle of the scoop position is greater than the thickness of the handle, and the width of the recess is greater than the width of the handle, so that fingers can easily reach into the scoop position and grip the handle.

[0027] Preferably, the bottom surface of the container lid is provided with a rubber ring, which is adapted to the shape and size of the container opening. When the container lid is closed and locked, the rubber ring abuts against the edge of the container opening to prevent the contents of the container from getting damp. At the same time, it also reduces the production precision requirements of the locking position and locking protrusion to a certain extent. The production error can be compensated by the elastic deformation of the rubber ring.

[0028] Preferably, the container lid includes a separate outer shell, a main frame, and a spoon housing, which facilitates mold making for different structures and selection of appropriate materials. The outer shell is preferably made of a pet-resistant metal plate, and the main frame is installed inside the outer shell to support the shape of the metal shell and prevent it from easily deforming.

[0029] The inner cavity is formed between the main frame and the outer shell. The spoon holder shell and the main frame are provided with a matching snap-fit ​​structure. The spoon holder shell serves as part of the bottom structure of the container lid and is provided with the spoon position.

[0030] The cross-sectional structure of the rubber ring is S-shaped, with an upward-opening slot and a downward-opening slot. The main frame is provided with a rubber ring groove for housing the rubber ring. The rubber ring groove has a downward protruding strip that fits the upward slot. The spoon housing has an upward-protruding retaining edge that fits the downward slot.

[0031] The upward slot engages with the downward protrusion, thereby pre-installing the rubber ring on the main frame. The edge engages with the downward slot and makes the rubber ring abut against the rubber ring groove. At the same time, the spoon housing is engaged with the main frame through a snap-fit ​​structure. The rubber ring is clamped by the spoon housing and the frame housing, making the overall assembly convenient and sturdy.

[0032] The beneficial effects of this utility model are as follows: the owner can easily unlock or lock the lid by pushing the push button, which is convenient and quick. Compared with the prior art, this utility model sets the push button inside the container lid and does not expose it. At the same time, a groove with a first opening is provided on the top surface of the container lid, so that the owner's pushing action is not directly seen by the pet, making it difficult for the pet to learn to open the lid. On the other hand, by setting the elastic element, the locking effect is more secure and will not be easily unlocked due to the pet's pushing or impact. Attached Figure Description

[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0060] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0061] like Figures 1 to 11 As shown, a convenient and pet-proof storage device includes a container lid A and a container B with a container opening. A hinge structure is provided between the container lid A and the container B. The container lid A can be flipped relative to the container B to cover or expose the container opening.

[0062] In this embodiment, container B opens upwards to form the container opening, and includes a separate inner bucket 12 and a metal outer bucket 11 to prevent pets from scratching it. The outer bucket 11 has symmetrically recessed hand grooves 1102 on its front and rear sides for easy lifting and carrying. Two rollers 1104 are provided on one side of the outer bucket 11 for easy dragging and carrying. Two anti-slip feet 1103 are provided on the other side of the outer bucket 11 opposite to the rollers 1104.

[0063] The container B has at least one locking position 1101 located away from the hinge structure, the locking position 1101 extending outward along the opening direction of the container opening to exceed the edge of the container opening.

[0064] The inner side of the container lid A is provided with at least one push buckle 2. The push buckle 2 has a locking protrusion 201 that is adapted to the locking position 1101. The end face of the push buckle 2 near the hinge structure is provided as a push end 202. The push buckle 2 can slide in a direction away from or near the locking position 1101.

[0065] The top surface of the container lid A is recessed downwards to form a groove 101. The groove 101 has a first opening on the side away from the hinge structure to expose the push end 202, preventing the pet from looking directly at it while pushing, and also serving as a sheltered structure for the fingers. The push end 202 is recessed away from the hinge structure to facilitate gripping with fingers.

[0066] The storage device also includes at least one elastic element 3, one end of which is connected to the container lid A and the other end is connected to the push buckle 2. The elastic element 3 has a tendency to pull the locking protrusion 201 close to the locking position 1101.

[0067] Applying force causes the locking protrusion 201 of the push buckle 2 to move away from the locking position 1101, compressing the elastic element 3, unlocking the container lid A, and allowing the container lid A to be flipped up and opened;

[0068] When the container lid A is flipped down and close to the container opening, force is applied again to move the locking protrusion 201 of the push buckle 2 away from the locking position 1101. The locking protrusion 201 enters the locking position 1101, and the force is stopped. The elastic member 3 extends and pulls the locking protrusion 201 close to the locking position 1101, thereby locking the container lid A. The container lid A cannot be flipped open.

[0069] To make it easier for the breeder to close the lid, in this embodiment, the locking position 1101 is a forward-opening hook groove structure, the locking protrusion 201 protrudes backward and has a guide slope 201a at the bottom, and the rotation trajectory of the locking position 1101 and the guide slope coincides.

[0070] When the container lid A is folded down close to the container opening and no external force is applied to the push button 2, the guide slope 201a contacts the top of the locking position 1101 and slides downward. The locking protrusion 201 moves away from the locking position 1101, and the elastic element 3 is compressed until the guide slope 201a completely slides past the top of the locking position 1101. The locking protrusion 201 enters the locking position 1101, and the elastic element 3 automatically releases and extends to pull the locking protrusion 201 close to the locking position 1101, locking the container lid A. The breeder only needs to press the container lid A to close the lid.

[0071] In this embodiment, the container cover A has a three-dimensional structure and at least the position near the lock position 1101 is a cavity structure, which is designated as the inner cavity.

[0072] The inner cavity houses the push-button 2 and the elastic element 3. The first opening communicates with the inner cavity, and the bottom of the inner cavity has a second opening 401 for the locking position 1101 to enter. This design avoids exposing small parts such as the push-button 2 and the elastic element 3, making the overall shape of the container lid A simpler and also preventing dirt and grime from accumulating and being damaged by impacts.

[0073] In this embodiment, the first opening is no more than 10 centimeters away from the outer circumference of the container lid A, which makes it convenient for the thumb to grasp the front end of the container lid A and cooperate with other fingers gripping the push end 202 to flip the container lid A.

[0074] In this embodiment, there are two elastic elements 3, specifically two helical springs. The bottom of the inner cavity protrudes upward to form a column 402 corresponding to the number of elastic elements. The outer periphery of the column 402 protrudes away from the locking position 1101 to form a blocking part 402a that can lock the first end of the spring. The push buckle 2 is provided with a supporting part 203b for the second end of the spring to support.

[0075] The spring pushes the push buckle 2 towards the hinge structure. Specifically, the compressible length of the spring after installation is greater than the front and rear thickness of the locking protrusion.

[0076] In this embodiment, the bottom sides of the push button 2 have strip-shaped mounting grooves 203 adapted to the two springs. The column 402 is located in the mounting groove 203 away from the hinge structure. The groove wall of the mounting groove 203 near the hinge structure serves as the top holding part 203b. The size of the mounting groove 203 prevents the built-in spring from bending.

[0077] The distance between the blocking part 402a and the supporting part 203b is less than or equal to the axial length of the spring when it is fully extended, but greater than the length of the spring when it is fully compressed.

[0078] In this embodiment, each mounting groove 203 has a vertically extending, horizontally oriented strip groove 203a, the length and width of which are smaller than the mounting groove 203. The top surface of the column 402 has a downward-facing fixing hole 402b (specifically a screw hole). A fixing member 10 (specifically a screw) passes through the strip groove 203a from top to bottom. The lower part of the fixing member 10 is fixed to the fixing hole 402b, and the upper part (i.e., the screw nut) is engaged with the top surface of the strip groove 203a. Under the constraint of the strip groove 203a and the screw, the push-button 2 slides horizontally to lock or unlock.

[0079] The bottom of the inner cavity is provided with at least two upward protruding latches 403. The latches 403 are opposite each other and slide to secure the push buckle 2. In this embodiment, the two opposite latches 403 are specifically located on both sides of the push buckle 2. The push buckle 2 can be pre-installed by pressing and engaging before the screws are installed. At the same time, the horizontal movement of the push buckle 2 is further limited to ensure accurate and quick unlocking or locking.

[0080] The bottom surface of the container lid A has an upwardly recessed spoon position 601, on which a grain spoon 7 is provided. The grain spoon 7 and the container lid A are provided with one or more of the following: a locking structure, a magnetic structure, and a detachable adhesive structure. In this embodiment, one end of the spoon position 601 has a locking slot 603 adapted to the edge of the grain spoon 7, and a first magnet 8 is provided corresponding to the handle position of the grain spoon 7. A second magnet 9 is built into the handle of the grain spoon 7. When placing the grain spoon 7, the edge of the grain spoon 7 away from the handle is locked into the locking slot 603, and then the handle is brought closer to the spoon position 601 to be attracted and fixed.

[0081] The depth of the recess at the handle of the scoop position 601 corresponding to the grain scoop 7 is greater than the thickness of the handle, and the width of the recess is greater than the width of the handle, so that fingers can easily reach into the scoop position 601 to grip the handle.

[0082] The bottom surface of the container lid A is provided with a rubber ring 5, which is adapted to the shape and size of the container opening (specifically, the opening of the inner barrel 12 in this embodiment). When the container lid A is closed and locked, the rubber ring 5 abuts against the edge of the container opening to prevent the contents of the container B from getting damp. At the same time, it also reduces the production precision requirements of the locking position 1101 and the locking protrusion 201 to a certain extent. The production error can be compensated by the elastic deformation of the rubber ring 5.

[0083] In this embodiment, the container lid A includes a separate outer shell 1, a main frame 4, and a spoon housing 6, which facilitates mold making for different structures and selection of appropriate materials. The outer shell 1 is preferably made of a metal plate that is resistant to pet scratches. The outer shell 1 is flush with the outer periphery of the outer bucket 11. The main frame 4 is installed inside the outer shell 1 to support the shape of the metal outer shell 1 and prevent it from being easily deformed.

[0084] The inner cavity is formed between the main frame 4 and the outer shell 1. The spoon position shell 6 and the main frame 4 are provided with a matching snap-fit ​​structure. The spoon position shell 6 serves as part of the bottom structure of the container lid A and is provided with the spoon position 601.

[0085] The cross-sectional structure of the rubber ring 5 is S-shaped, with an upward-opening slot and a downward-opening slot. The main frame 4 is provided with a rubber ring groove 404 that can house the rubber ring 5. The rubber ring groove 404 has a lower protrusion that adapts to the upward slot. The spoon housing 6 has an upward-protruding retaining edge 602 that adapts to the downward slot.

[0086] The upward slot engages with the downward protrusion, and the rubber ring 5 is pre-installed on the main frame 4. The locking edge 602 engages with the downward slot and makes the rubber ring 5 abut against the rubber ring groove 404. At the same time, the spoon housing 6 is engaged with the main frame 4 through the locking structure. The rubber ring 5 is clamped by the spoon housing 6 and the frame housing, making the overall assembly convenient and sturdy.

[0087] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
