Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology and relates to a doghouse. Background Technology

[0002] A dog kennel is a product used in pet living environments. It primarily serves as a resting place for pets, providing a safe and comfortable sleeping space. Dog kennels come in various shapes, with some designed as boxes and equipped with openable / closable lids. Opening the lid facilitates cleaning and disinfection of the dog kennel.

[0003] For example, Chinese patent literature discloses a foldable outdoor storage box (application number: 202421718514.6), including a storage box body, a lid, and a support structure. The lid is hinged at the opening of the storage box body and supported by the support structure. When the support structure uses a support rod, the top of the support rod is hinged to the lid, and the storage box body is provided with a limiting support member that cooperates with the tail end of the support rod. The limiting support member has multiple limiting grooves. When using the box, the tail end of the support rod is manually placed into the corresponding limiting groove, and the limiting groove limits and supports the tail end of the support rod, thereby supporting the lid when it is flipped open. The storage box with this structure has the following shortcomings: the tail end of the support rod is only fixed by the limiting groove. In actual use, especially in outdoor environments or when subjected to external forces, this positioning method is prone to swaying left and right due to the deformation of the support rod itself or assembly gaps, thus disengaging from the limiting groove and causing the lid to close unexpectedly. In addition, when the storage box is used outdoors and is disturbed by external factors such as wind, the lid may tend to flip backward. This may not only cause the end of the support rod to disengage from the limiting groove, resulting in poor stability, but may also cause the lid to close suddenly, causing accidental injury to the user. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a doghouse that solves the problem that existing doghouses, when using support rods to support the lid, are prone to the support rods coming loose, resulting in poor stability.

[0005] The purpose of this utility model can be achieved through the following technical solution: A dog kennel includes a lid, a bottom plate, a front plate, a back plate, and two side plates arranged opposite to each other. The rear side of the lid is hinged to the back plate. The dog kennel is characterized by further including a support bar that is straight and bent at the lower end. One of the side plates is provided with a flat guide hole that passes through its upper edge. A limiting protrusion located at the opening of the guide hole is integrally formed on the hole wall at the upper end of the guide hole. The limiting protrusion is hook-shaped, with its straight part horizontally arranged and its bent end having a bent flange. The support bar passes through the guide hole and its upper end extends out of the guide hole and is hinged to the lid. When the lid is flipped up, the lower end of the support bar can move to below the straight part of the limiting protrusion and abut against the bent end.

[0006] In this dog kennel, when the lid is flipped up, the lower end of the support bar is moved below the straight portion of the limiting protrusion and rests against the curved end, thus supporting the lid. In this state, firstly, because the curved end of the limiting protrusion has a bent flange, the lower end of the support bar is prevented from slipping off the limiting protrusion; secondly, because the limiting protrusion has a horizontal straight portion and the lower end of the support bar is bent, the limiting protrusion can limit the upward movement of the support bar. This structure ensures that when the doghouse is used outdoors, even if it is disturbed by external factors such as wind, the lid tends to flip back. The flat part can also block the bent part at the lower end of the support bar, thus stably confining the support bar to the limiting protrusion and effectively preventing the support bar from detaching from the limiting protrusion, thereby having high stability. Thirdly, the guide hole adopts a flat structure, and its two side hole walls can also limit the left and right swaying of the support bar, further preventing the support bar from detaching from the limiting protrusion due to swaying.

[0007] Based on the analysis of the above three aspects, it can be seen that after the lid of this dog kennel is opened, the special shape design of the limiting protrusion can effectively limit the lower end of the support bar, greatly reducing the risk of the support bar detaching from the limiting protrusion and greatly improving stability.

[0008] Under normal use, the dog kennel lid is closed. To open the lid, simply flip it upwards. Since the upper end of the support bar is hinged to the lid, it moves upwards along with the lid. During this process, the flat guide hole limits the lateral movement of the support bar, restricting its upward movement and facilitating the precise alignment and movement of the lower end of the support bar to the limiting protrusion. Furthermore, when the lower end of the support bar abuts against the straight portion of the limiting protrusion while the lid is being flipped, its position can be roughly determined. At this point, simply adjusting the angle of the support bar quickly positions its lower end against the curved end of the limiting protrusion, achieving stable positioning of the lid at that opening angle. This design effectively solves the problem of difficulty in accurately positioning the support bar relative to the limiting protrusion due to the limiting protrusion being hidden inside the guide hole, thus making operation more convenient.

[0009] In the aforementioned dog kennel, the limiting protrusion is integrally formed on the inner wall of the guide hole. The horizontal thickness of the curved end of the limiting protrusion is greater than the horizontal thickness of its straight portion. The support strip enters the guide hole from the outside of the straight portion of the limiting protrusion. The thinner horizontal thickness of the straight portion of the limiting protrusion provides clearance for the support strip, allowing the lower end of the support strip to move smoothly below the straight portion and rest against the curved end. The greater horizontal thickness of the curved end results in higher structural strength and provides more stable support for the kennel lid.

[0010] In the aforementioned dog kennel, the guide hole has a strip-shaped opening extending in the front-to-back direction, and the length of the straight portion of the limiting protrusion is greater than the length of the opening. The strip-shaped opening of the guide hole allows the support bar to swing in the front-to-back direction, ensuring the lid can be smoothly flipped up or closed. When the lid is flipped up to a certain position, the lower end of the support bar moves below the straight portion of the limiting protrusion. At this point, because the length of the straight portion is greater than the length of the guide hole, it effectively blocks the lower end of the support bar, preventing it from detaching from the guide hole and causing the lid to flip completely. Furthermore, when the lid is disturbed by external factors such as wind, it also prevents the lid from flipping backward and causing the lower end of the support bar to detach from the limiting protrusion, thereby further improving safety.

[0011] In the aforementioned dog kennel, a C-shaped positioning protrusion with its opening facing backward is integrally formed on the inner wall of the lower end of the guide hole. The horizontal thickness of the upper half of the positioning protrusion is less than the horizontal thickness of its lower half. When the lid is closed, the support bar is located behind the positioning protrusion and its lower end is lower than the positioning protrusion. By flipping the lid upward, the lower end of the support bar can be positioned outside the upper half of the positioning protrusion and abut against the lower half of the positioning protrusion.

[0012] This dog kennel is primarily used for accommodating pets' daily activities and storing related items. When the lid is closed, the lower end of the support bar is below the positioning protrusion. When the support bar rests against the limiting protrusion, the lid has a larger opening angle, facilitating cleaning of the kennel's interior. When the support bar rests against the positioning protrusion, the lid opens at a smaller angle, allowing for ventilation. The "C"-shaped positioning protrusion is designed with a thinner upper section than a thinner lower section. This allows the upper section to avoid the support bar when the lid is open at a small angle, ultimately positioning the lower end of the support bar outside the upper part of the positioning protrusion and against it, ensuring stable lid positioning. This structure not only provides two opening angles for the lid but also ensures stable and reliable opening and closing.

[0013] In the aforementioned dog kennel, the rotation center line of the support bar is parallel to the rotation center line of the lid. This parallelism allows the support bar to swing stably back and forth around its upper end as the lid flips up or closes, facilitating its contact with the limiting and positioning protrusions, thus making operation more convenient.

[0014] In the aforementioned dog kennel, the bottom surface of the lid has a strip-shaped groove parallel to the rotation center line of the lid. The upper end of the support bar is bent to the side to form an L-shape, and the upper end of the support bar is rotatably positioned within the strip-shaped groove. A limiting piece is also fixedly connected to the bottom surface of the lid to limit the upper end of the support bar within the strip-shaped groove. Designing the upper end of the support bar as an L-shape bent to the side and rotatably positioned within the strip-shaped groove, while simultaneously using the limiting piece fixedly connected to the bottom surface of the lid, effectively limits the upper end of the support bar within the strip-shaped groove. This ensures smooth rotation of the support bar while effectively preventing it from detaching from the lid during movement, thus guaranteeing the stability and reliability of the entire lid opening and closing structure. Furthermore, this structure is easy to process and can reduce manufacturing costs.

[0015] In the aforementioned dog kennel, the support bar is a component formed by bending a straight metal strip at both ends towards the same side. Using a bent metal strip to form the support bar not only ensures sufficient strength to support the lid, but also facilitates manufacturing, reduces costs, and allows the dog kennel to maintain a long service life even in outdoor environments.

[0016] Compared with existing technologies, this doghouse has the following advantages:

[0017] 1. When this dog kennel is used outdoors, even if the lid tends to flip back due to external factors such as wind, the lid will not suddenly close because the support bar is firmly positioned on the limiting protrusion and the guide hole restricts the left and right sway of the support bar. This avoids possible accidental injury to the user and greatly improves the safety of the dog kennel.

[0018] 2. The lid of this dog kennel has two opening angles, which can well meet the requirements of ventilation and cleaning.

[0019] 3. The dog kennel's body is made of plastic, and the guide holes and limiting protrusions on the side panels are injection molded together with the side panels. Clearly, this dog kennel does not use precision components such as pneumatic telescopic rods that are easily affected by the environment to achieve the opening and closing function of the kennel lid. Instead, the guide holes, positioning protrusions, and support strips integrally molded on the side panels work together to stably meet the functional requirements. This design eliminates concerns about problems such as poor extension and retraction or jamming caused by rust, dirt accumulation, or corrosion of traditional telescopic rods. Even with long-term outdoor use, it can still maintain a stable and reliable lid opening and closing function, ultimately achieving a long service life even in outdoor environments.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figures 1 to 3 As shown, this dog kennel includes a rectangular box body, a lid 1 covering the top of the box body, and a straight support bar 6. The box body includes a bottom plate 2, a front panel 3, a back panel 4, and two side panels 5 arranged opposite each other. The front panel 3 has a door 9 for the pet to enter and exit. The rear side of the lid 1 is hinged to the upper edge of the back panel 4. The right side panel 5 has a flat guide hole 51 that runs through its upper edge. Of course, in actual manufacturing, the guide hole 51 can also be provided on the left side panel 5. A limiting protrusion 52 is integrally formed on the upper wall of the guide hole 51 at its opening 511. The limiting protrusion 52 is hook-shaped, with its straight part horizontally positioned and its curved end having a bent retaining edge.

[0033] Under normal use, the lid 1 of the dog kennel is in the closed position, such as... Figure 3 As shown, at this time, the lower end of the support bar 6 is at the bottom of the guide hole 51. Figure 4 and Figure 5 As shown, the orifice 511 of the guide hole 51 is strip-shaped and extends in the front-to-back direction, and the length of the straight portion of the limiting protrusion 52 is greater than the length of the orifice 511. After the box cover 1 is flipped upward, the lower end of the support bar 6 can move to below the straight portion of the limiting protrusion 52 and abut against the end of the curved end. Figure 7 and Figure 8 As shown, the limiting protrusion 52 is integrally formed on the inner wall of the guide hole 51. The horizontal thickness of the curved end of the limiting protrusion 52 is greater than the horizontal thickness of its straight part. The support bar 6 passes through the guide hole 51 from the outside of the straight part of the limiting protrusion 52.

[0034] like Figure 8 and Figure 9 As shown, a C-shaped positioning protrusion 53 with its opening facing backward is integrally formed on the inner wall of the lower end of the guide hole 51. The horizontal thickness of the upper half of the positioning protrusion 53 is less than the horizontal thickness of its lower half. When the box cover 1 is closed, the support bar 6 is behind the positioning protrusion 53 and its lower end is lower than the positioning protrusion 53. By flipping the box cover 1 upward, the lower end of the support bar 6 can be placed outside the upper half of the positioning protrusion 53 and abut against the lower half of the positioning protrusion 53.

[0035] like Figure 6 As shown, the support bar 6 is a component formed by bending a straight metal bar at both ends to the same side.

[0036] like Figure 10As shown, the rotation center line of the support bar 6 is parallel to the rotation center line of the cover 1. To facilitate the installation of the support bar 6, a strip-shaped groove 11 parallel to the rotation center line of the cover 1 is provided on the bottom surface of the cover 1. The upper end of the support bar 6 is bent to the side to form an L-shape, and the upper end of the support bar 6 is rotatably positioned within the strip-shaped groove 11. A limiting piece 7 is also fixedly connected to the bottom surface of the cover 1 to limit the upper end of the support bar 6 within the strip-shaped groove 11. The limiting piece 7 is fixedly connected to the cover 1 by screws 8.

[0037] This doghouse is primarily used for accommodating the pet's daily activities and storing related items. When lid 1 is closed, as... Figure 3 As shown, the lower end of the support bar 6 is below the positioning protrusion 53. When the pet in the doghouse needs ventilation, open the lid 1 slightly upwards, then manually pull the support bar 6 forward to move its lower end to the outer side of the upper part of the positioning protrusion 53. Then release the lid 1. Figure 9 As shown, the lower end of the support bar 6 can abut against the lower half of the positioning protrusion 53 to achieve stable positioning of the box cover 1.

[0038] When cleaning the inside of the doghouse, lift the lid 1 upwards until the lower end of the support bar 6 abuts against the straight part of the limiting protrusion 52. At this point, the lid 1 cannot be lifted any further. Then, push the support bar 6 backwards until it can no longer be pushed. After that, the lid 1 can be released. Figure 4 As shown, the lid 1, by its own weight, causes the lower end of the support bar 6 to abut against the bent end of the limiting protrusion 52, thus positioning the lid 1 at this opening angle. This design effectively solves the problem that the limiting protrusion 52 is hidden inside the guide hole 51, making it difficult for users to accurately position the relative position of the support bar 6 and the limiting protrusion 52 during operation. This makes operation more convenient and avoids the reliability issues and safety hazards caused by the lid 1 closing instantly due to the failure of the support bar 6 and the limiting protrusion 52 to abut against each other.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0040] Although this document frequently uses terms such as 1. lid; 11. groove; 2. bottom plate; 3. front panel; 4. back plate; 5. side plate; 51. guide hole; 511. orifice; 52. limiting protrusion; 53. positioning protrusion; 6. support strip; 7. limiting piece; 8. screw; and 9. door, the possibility of using other terms is not excluded.
