Description

Technical Field

[0001] This utility model relates to the field of pet supplies, and in particular to the field of pet cage door hinges. Background Technology

[0002] Pet cage doors, especially the top doors, often use a swing-type opening and closing mechanism. These doors are typically connected to the cage body via hinges to achieve the swing. Existing hinges usually lack a limiting mechanism, meaning the cage door only has one open and one closed state, with the angle between them typically being 90° or 270°. In actual use, depending on the placement environment and the activity, users often need to switch between 90° and 270° opening. For example, when only retrieving pet supplies, the cage door only needs to be opened briefly, in which case a 90° opening is sufficient. However, when the cage door needs to be opened for extended periods for cleaning or when the pet cage is used as a playpen, if the door remains only open at 90°, the pet cage will occupy a significant amount of space for an extended period, hindering user operation, and the pet may easily climb over the door and close it.

[0003] It is evident that existing pet cages have relatively limited opening angles for their cage doors, making it difficult to meet the diverse needs of users. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a pet cage door hinge that can achieve multiple opening states and helps to improve the flexibility of pet cage use.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A pet cage door hinge, comprising:

[0007] The first connector is used to connect the cage body;

[0008] The second connector is used to connect the cage door;

[0009] The second connector is rotatably mounted on the first connector and can rotate relative to the first connector from front to back. The second connector has a first angular position, a second angular position and a third angular position that are sequentially distributed from front to back along its rotation direction.

[0010] A locking structure is provided between the first connector and the second connector, the locking structure being used to restrict the rearward rotation of the second connector when the second connector is in the second angular position;

[0011] The second connector can be moved relative to the first connector in a specified direction under the action of an external force to unlock the locking structure.

[0012] Preferably, when the second connector is in the first angular position, the cage door it is connected to is in a horizontal position; when the second connector is in the second angular position, the cage door it is connected to is in a vertical position and is located above the rotation axis of the second connector; when the second connector is in the third angular position, the cage door it is connected to is in a vertical position and is located below the rotation axis of the second connector.

[0013] Preferably, when the second connector is in the second angle position, the cage door it is connected to is tilted backward at an angle relative to the vertical plane where the rotation axis of the second connector is located.

[0014] Preferably, the second connector is rotatably mounted on the first connector via a pivot shaft. The first connector or the second connector is provided with a strip-shaped sliding hole. The pivot shaft is located in the sliding hole and can move radially along the sliding hole. When the second connector is in the second angular position, the specified direction is parallel to the length direction of the sliding hole.

[0015] Preferably, the locking structure includes a first blocking portion disposed on the first connecting member and a second blocking portion disposed on the second connecting member. When the second connecting member is in the second angular position, the first blocking portion and the second blocking portion abut against each other in the front-back direction to restrict the rearward rotation of the second connecting member. The second connecting member can be moved in the specified direction under the action of an external force to make the first blocking portion and the second blocking portion misaligned to unlock the locking structure.

[0016] Preferably, the pivot shaft and the sliding hole are configured such that when the second connector is in the second angular position, the second connector can move downwards by its own weight or the weight of the cage door to align and abut against the first blocking part and the second blocking part; the specified direction is an upward direction.

[0017] Preferably, the sliding hole is provided on the second connector; the first connector is provided with a limiting part, and the second connector is provided with a cylindrical limiting surface. During the process of the second connector rotating forward from the third angle position to the second angle position, the central axis of the limiting surface coincides with the central axis of the pivot shaft, and the limiting part slides against the limiting surface to restrict the radial movement of the pivot shaft along the sliding hole.

[0018] Preferably, the limiting surface is cylindrical and located in front of the pivot shaft, and the central axis of the limiting surface coincides with the central axis of the pivot shaft. When the second connector is in the third angle position, the top end of the limiting part is located above the limiting surface and within the vertical projection range of the limiting surface.

[0019] Preferably, the first connector is provided with a third blocking part, and the second connector is provided with a fourth blocking part. When the second connector is in the first angular position, the third blocking part and the fourth blocking part abut against each other in the front-back direction to restrict the pivot shaft from sliding radially along the sliding hole.

[0020] Preferably, the first connector is provided with a first connecting structure for connecting the cage door, and the second connector is provided with a second connecting structure for connecting the cage body. Both the first connecting structure and the second connecting structure are detachable connecting structures.

[0021] The beneficial effects of this utility model are as follows: The locking structure of this hinge can restrict the second connecting member from rotating from the second angle position to the third angle position. After the locking structure is unlocked, the second connecting member can continue to rotate from the second angle position to the third angle. This allows the cage door connected to the second connecting member to have two different opening angles, which can adapt to the diverse needs of users and effectively improve the flexibility of pet cage use. Furthermore, since the unlocking of the locking structure can be achieved by moving the second connecting member in a specified direction, in actual operation, the user can operate the cage door with one hand to simultaneously rotate and open the cage door and unlock the locking structure. The operation is simple, quick, and convenient. Attached Figure Description

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 5According to a first preferred embodiment of the present invention, a pet cage door hinge includes: a first connector 10 for connecting the cage body; and a second connector 20 for connecting the cage door. The second connector 20 is rotatably mounted on the first connector 10 and can rotate relative to the first connector 10 from front to back. The second connector 20 has a first angular position, a second angular position, and a third angular position sequentially distributed from front to back along its rotation direction. A locking structure is provided between the first connector 10 and the second connector 20. The locking structure is used to restrict the rearward rotation of the second connector 20 when it is in the second angular position. The second connector 20 can move relative to the first connector 10 in a specified direction under the action of an external force to unlock the locking structure. This hinge features a locking structure that restricts the second connecting member 20 from rotating from a second angle position to a third angle position. After the locking structure is unlocked, the second connecting member 20 can continue to rotate from the second angle position to the third angle position. This allows the cage door connected to the second connecting member 20 to have two different opening angles, adapting to diverse user needs and effectively improving the flexibility of pet cage use. Furthermore, since the locking structure can be unlocked by moving the second connecting member 20 in a specified direction, in actual operation, users can operate the cage door with one hand to simultaneously rotate and unlock the locking structure, making operation simple, quick, and convenient.

[0035] As a first preferred embodiment of this utility model, it may also have the following additional technical features:

[0036] In this embodiment, when the second connector 20 is in the first angle position, the cage door it connects to is horizontal; when the second connector 20 is in the second angle position, the cage door it connects to is vertical and located above the rotation axis of the second connector 20; when the second connector 20 is in the third angle position, the cage door it connects to is vertical and located below the rotation axis of the second connector 20. In use, the first angle position corresponds to the cage door being closed, the second angle position to the cage door being normally open, suitable for most short-term operations such as taking out pet food and supplies, and the third angle position to the cage door being retracted. At this time, the cage door rotates backward to be close to the rear cage grille, effectively reducing the space occupied by the pet cage and facilitating operation inside the pet cage from all directions. The pet cage can also be used as a fence. This angle setting method can adapt to the needs of most situations. In other embodiments, the angle states of the first, second, and third angle positions can be flexibly adjusted according to different pet cage structures and requirements, and are not limited to this.

[0037] In this embodiment, when the second connector 20 is in the second angle position, the cage door it is connected to is tilted backward at an angle relative to the vertical plane where the rotation axis of the second connector 20 is located. In this way, together with the locking structure, the second connector 20 and the cage door can be maintained in the second angle position. Especially when applied to the upper cage door of a pet cage, it can effectively prevent the cage door from closing accidentally and make it convenient to use.

[0038] In this embodiment, the second connector 20 is rotatably mounted on the first connector 10 via a pivot shaft 41. The first connector 10 or the second connector 20 is provided with a strip-shaped sliding hole 42. The pivot shaft 41 is located inside the sliding hole 42 and can move radially along the sliding hole 42. When the second connector 20 is in the second angle position, the specified direction is parallel to the length direction of the sliding hole 42. The structure is simple, easy to process, manufacture and assemble, and helps to reduce product costs. Furthermore, the operation of unlocking the locking structure in the specified direction is to pull up or push down the cage door, which effectively facilitates the unlocking operation.

[0039] In this embodiment, the locking structure includes a first blocking part 31 disposed on the first connecting member 10 and a second blocking part 32 disposed on the second connecting member 20. When the second connecting member 20 is in the second angle position, the first blocking part 31 and the second blocking part 32 abut against each other in the front-back direction to restrict the rearward rotation of the second connecting member 20. The second connecting member 20 can move in a specified direction under the action of external force to make the first blocking part 31 and the second blocking part 32 staggered to unlock the locking structure. This locking structure is simple, reliable and easy to process and manufacture.

[0040] In this embodiment, the pivot shaft 41 and the sliding hole 42 are configured such that when the second connector 20 is in the second angle position, the second connector 20 can move down by its own weight or the weight of the cage door to align and abut against the first blocking part 31 and the second blocking part 32. The specified direction is upward, that is, when the second connector 20 rotates with the cage door to the second angle position, it can fall a short distance by its own weight to lock itself. When the locking structure needs to be unlocked, simply lift the cage door. The operation is simple and can reduce the size of the protruding parts of the first connector 10 and the second connector 20, which helps to reduce the space occupied by the pet cage during use and makes it convenient to place and use.

[0041] In this embodiment, the sliding hole 42 is provided on the second connector 20; the first connector 10 is provided with a limiting part 11, and the second connector 20 is provided with a cylindrical limiting surface 21. During the process of the second connector 20 rotating forward from the third angle position to the second angle position, the central axis of the limiting surface 21 coincides with the central axis of the pivot shaft 41, and the limiting part 11 slides against the limiting surface 21 to restrict the radial movement of the pivot shaft 41 along the sliding hole 42. This can prevent the cage door from moving relative to the pivot shaft 41 in the radial direction of the pivot shaft 41 during the closing process, which would cause the second connector 20 to be blocked by the first connector 10 and thus cause the cage door to jam and be unable to close, making operation and use convenient.

[0042] In this embodiment, the limiting surface 21 is cylindrical and located in front of the pivot shaft 41. The central axis of the limiting surface 21 coincides with the central axis of the pivot shaft 41. When the second connecting member 20 is in the third angle position, the top end of the limiting part 11 is located above the limiting surface 21 and within the vertical projection range of the limiting surface 21, ensuring the limiting effect on the second connecting member 20 and helping to reduce the exposure of the limiting part 11. At the same time, it can also limit the forward translation of the cage door during the closing process, ensuring the smooth closing of the cage door. In this embodiment, a protruding plate 14 is provided on the first connecting member 10, and the limiting part 11 is also cylindrical and adapted to the limiting surface 21. In other embodiments, the limiting part 11 may also adopt other suitable shapes and structures.

[0043] In this embodiment, the first connecting member 10 is provided with a third blocking part 12, and the second connecting member 20 is provided with a fourth blocking part 22. When the second connecting member 20 is in the first angular position, the third blocking part 12 and the fourth blocking part 22 abut against each other in the front-back direction to restrict the radial sliding of the pivot shaft 41 along the sliding hole 42. This allows for accurate positioning and limiting of the front-back position when the cage door is closed, preventing backward movement after the cage door is closed and thus affecting normal use. In this embodiment, the third blocking part 12 and the fourth blocking part 22 are mutually adaptable inclined surfaces, which helps guide the second connecting member 20 to the predetermined front-back position during the cage door closing process.

[0044] In this embodiment, the first connector 10 is provided with a first connecting structure 13 for connecting the cage door, and the second connector 20 is provided with a second connecting structure 23 for connecting the cage body. Both the first connecting structure 13 and the second connecting structure 23 are detachable connecting structures, which facilitates assembly and disassembly, and is convenient for production and use. In this embodiment, both the first connecting structure 13 and the second connecting structure 23 include a connecting groove 51 and a connecting block 52. The connecting block 52 is located in the connecting groove 51 and is adapted to the spacing between the two rods at the corresponding positions of the pet cage. At the same time, the connecting block 52 is locked and fixed to the connecting groove 51 by a bolt assembly 53, thereby realizing the connection and fixation on the pet cage. In other embodiments, the first connector 10 and the second connector 20 may also adopt other commonly used detachable connecting structures such as snap-fit ​​structures and binding structures, or they may be directly connected to the cage door or cage body by welding, bonding, or other methods.

[0045] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0046] This utility model provides a second preferred embodiment. In this embodiment, a sliding hole 42 is still provided on the first connecting member 10 or the second connecting member 20, and the first connecting member 10 and the second connecting member 20 are also rotatably connected by a pivot shaft 41. The movement of the second connecting member 20 in a specified direction is achieved by the radial movement of the pivot shaft 41 along the sliding hole 42. At the same time, the first blocking part 31 and the second blocking part 32 are used to limit the continued rearward rotation of the second connecting member 20 at the second angular position. Unlike the first preferred embodiment, in this embodiment, the second connecting member 20 moves towards... When rotated to the second angular position, the second connecting member 20 does not need to move radially along the pivot shaft 41. The first blocking part 31 and the second blocking part 32 abut against each other. Then, by moving the second connecting member 20 in a specified direction, the first blocking part 31 and the second blocking part 32 are offset vertically to unlock the locking structure. This specified direction can be upward or downward. When the specified direction is downward, elastic devices such as springs or sheet springs can be added to maintain the position of the second connecting member 20 to keep the first blocking part 31 and the second blocking part 32 abutting. Those skilled in the art can easily understand the arrangement of the structure in this second preferred embodiment based on the above description and reference to the first preferred embodiment. It is simple and can be achieved simply by adjusting the initial relative position of the sliding hole 42 and the pivot shaft 41.

[0047] This utility model also provides a third preferred embodiment. This embodiment is the same as the first preferred embodiment in that the locking structure still uses the first blocking part 31 and the second blocking part 32 as the locking structure. The difference from the first preferred embodiment is that the sliding hole 42 is not used in this embodiment. The first connecting member 10 and the second connecting member 20 are only rotatably connected by the pivot shaft 41. However, it is set so that the second connecting member 20 can move relative to the first connecting member 10 in the axial direction of the pivot shaft 41 and this is taken as the specified direction. The first blocking part 31 and the second blocking part 32 are misaligned by the movement of the second connecting member 20 in the circumferential direction of the pivot shaft 41, thereby unlocking the locking device. Specifically, this can be achieved by making the length of the pivot shaft 41 longer than the length of the corresponding hole on the second connecting member 20 or the length of the corresponding hole on the first connecting member 10. Of course, other common methods can also be used to achieve this.

[0048] This utility model can also have other feasible embodiments. The specified direction can also be set to forward or backward, and only the relative positions of each part of the locking structure need to be adjusted accordingly. Alternatively, the locking structure can adopt other suitable structures. For example, a retractable pin can be set on the second connector 20, which is inserted into the pin groove on the first connector 10 to restrict the rearward rotation of the second connector 20 at the second angle position. A movable push rod connected to the pin is set on the side of the pin. The push rod abuts against the first connector 10. When the second connector 20 is pressed down, the pin can be retracted by the push rod and disengaged from the pin groove, thereby unlocking the locking device. In addition, the locking structure can also have other commonly used structures. Based on the inventive concept provided by this utility model, those skilled in the art can easily select or design from the prior art.

[0049] It should be noted that the directions such as up, down, front, and back in this utility model are based on the state in which this hinge is applied to the upper cage door of a pet and installed at the rear end of the upper cage door. This is also the installation position of this hinge in most cases. These orientation settings are only for the convenience of description and understanding and should not be construed as a limitation of this utility model. In actual use, this hinge can also be used in other required positions such as the side door and front door of the pet cage door. In this case, the various directions will also change with the installation position and installation angle of the hinge.

[0050] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
