Description

Technical Field

[0001] This utility model belongs to the field of pet cage technology, and in particular relates to the rotating hinge of the top door of a pet cage. Background Technology

[0002] Pet cages are common tools for pet feeding and transportation. Their top covers are usually designed as openable doors for easy feeding, cleaning, or interaction with pets. The stability of the connection between the top door and the cage body, the smoothness of opening and closing, and the ease of installation directly affect the user experience and pet safety.

[0003] Currently, the rotating connection structure of pet cage top doors mostly uses traditional hinges or simple pin connections. However, this type of connection has obvious shortcomings when applied to pet cage top doors:

[0004] 1. Complex installation with high precision requirements for holes: Existing connectors often require precise drilling at specific locations on the cage body mesh panel and the top door mesh panel for fixing. For mesh-like metal mesh panels, precise hole alignment is difficult, time-consuming, and labor-intensive, and drilling errors can easily lead to uneven rotation or structural misalignment after installation.

[0005] 2. Poor rotation smoothness and limiting mechanism: Simple pin connections may lack effective rotation guidance and limiting mechanisms. During the opening and closing of the top door, especially during the initial opening or near the closed position, problems such as jamming, deviation, or inability to accurately position the door in the fully open / closed state may occur, affecting the user experience.

[0006] 3. Poor compatibility with mesh structure: The frame of a pet cage is usually made up of crisscrossing mesh bars. Conventional flat-mounted hinges cannot fully utilize the three-dimensional structure of the mesh to achieve stable multi-point and multi-directional connections and stress distribution.

[0007] Therefore, there is an urgent need for a rotating hinge structure specifically designed for the top door of pet cages. It should have higher structural strength and stability to withstand frequent opening and closing and impact loads, simplify the installation process (especially adapting to the structural characteristics of metal mesh panels), ensure smooth and stable rotation and have good limiting function, and effectively adapt to the structure of the cage body and the top door mesh panel to achieve a stable and reliable connection. Utility Model Content

[0008] The purpose of this invention is to provide a rotating hinge for the top door of a pet cage to solve existing problems.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a rotating hinge for the top door of a pet cage, including a base, a plug, and a base. The base is an integral box-shaped structure formed by a front end face, a rear end face, a left end face, a right end face, and a top end face. The front end face of the base has a clearance groove that matches the plug. The left and right end faces of the base are "L"-shaped plate structures. A pivot groove is provided at the corner of the left and right end faces of the base. A track groove is provided on the lower side of the two opposing surfaces of the left and right end faces of the base. A slot is provided at the corner of the front end face and the left and right end faces of the base. A fixing hole is provided on the lower side of the rear end face of the base. A limit rod is fixed in the middle of the lower surface of the upper end face of the base. Guide blocks that are fixedly connected to the base are provided on the upper part of both sides of the clearance groove. An arc-shaped guide surface is provided on the lower surface of the guide block.

[0011] The plug-in has a "U" shaped plate structure. The lower limit holes that match the limit rod are opened on the lower sides of the two opposite surfaces of the plug-in. The upper limit hole is opened on the upper side of the surface of the plug-in away from the limit rod.

[0012] The base is an integrally formed structure consisting of a base plate and a U-shaped side plate. The base plate has symmetrically formed fixing slots on one surface. The two corners at both ends of the U-shaped side plate have auxiliary limiting slots that match the rotating shaft slots. The upper surfaces of the two bends of the U-shaped side plate are fixed with insert rods that match the slots. The center of one surface of the U-shaped side plate has a protrusion that matches the clearance slot, and the upper surface of the protrusion is fixed with a limiting post. The base plate has fixing screw holes that match the positions of the fixing holes. The two ends of the U-shaped side plate are fixed with sliders that match the track slots.

[0013] Furthermore, the shape and size of the clearance groove are adapted to the plug-in, and the shape and size of the limiting rod are adapted to the lower limiting hole. The base and the plug-in are fixed by the limiting rod and the lower limiting hole, forming the first rotating groove.

[0014] Furthermore, the position and size of the rotating shaft groove are adapted to the auxiliary limiting groove, and the rotating shaft groove and the auxiliary limiting groove form a second rotating groove.

[0015] Furthermore, the shape and size of the slot are adapted to the insertion rod, and the insertion rod and the slot cooperate with each other; the shape and size of the track groove are adapted to the slider, and the track groove and the slider cooperate with each other.

[0016] Furthermore, several reinforcing ribs are provided at the connection between the base plate and the U-shaped side plate, and the position of the fixing slot is adapted to the second rotating slot.

[0017] Furthermore, the shape and size of the base are adapted to the base, and the base and the base are fixed together by a limiting rod and a limiting post to secure the plug.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, the base adopts an integrated box-shaped structure, with the base formed integrally from a bottom plate and U-shaped side plates, and reinforcing ribs at the connection points, resulting in a strong overall structural rigidity and resistance to deformation. By using inserts to connect the mesh panel side posts, fixing slots to engage the vertical mesh strip posts, and auxiliary limiting slots to support the side posts, a three-point stable connection (insert point, fixing slot, and auxiliary limiting slot) is achieved between the pet cage top door and the cage body, effectively distributing the weight of the door and the torque and impact forces during opening and closing. The base and the base are finally fastened together with screws to form a robust overall frame.

[0020] In this utility model, a split design (base, plug-in, base) is adopted, and the installation steps are clear: first, put on the plug-in, then insert the base limiting rod, then lock the base fixing slot, and finally push the base to insert the plug-in into the slot and the slider into the track groove for positioning. Finally, tighten the screws. The cooperation between the slider and the track groove, and the cooperation between the plug-in and the slot, play an important guiding and coarse positioning role in the installation process, which significantly reduces the dependence on the accuracy of the mesh plate hole position, simplifies the installation process, and improves the installation efficiency.

[0021] In this invention, the base and the plug are connected by a limiting rod and a lower limiting hole to form a first rotating groove, and the base and the base are connected by a rotating shaft groove and an auxiliary limiting groove to form a second rotating groove. The double rotating groove structure works together to greatly improve the stability and smoothness of the rotation process and effectively prevent the door from shaking or shifting. The guide block and the arc-shaped guide surface on its lower surface provide smooth initial guidance at the beginning of the rotation (especially when opening) to reduce the feeling of jamming.

[0022] In this utility model, the design fully considers the structural characteristics of the pet cage mesh panel (side posts, vertical mesh strips); the U-shaped structure of the plug, the shape and position of the fixing slot (adapted to the second rotating slot), and the setting of the auxiliary limiting slot all enable it to fit tightly and effectively utilize the existing structure of the mesh panel for fixation without additional complex modifications; in particular, the matching of the protrusion and the avoidance slot, as well as the final insertion of the limiting post into the upper limit hole, lock the plug after installation to prevent it from coming out during operation, further enhancing the reliability and integrity of the connection.

[0023] In this invention, the robust structural design, smooth rotation characteristics, and reliable limiting reduce abnormal wear and impact damage between components, thus extending the service life of the hinge.

[0024] Therefore, the pet cage top door rotating hinge provided by this utility model significantly improves the stability of the top door connection, the smoothness of opening and closing, and the convenience of installation. It is especially suitable for pet cage scenarios that need to withstand a certain load and frequent opening and closing, and has high practical value and market prospects.
