Description

Technical Field

[0001] This utility model relates to the field of cage technology, specifically a cage locking hook. Background Technology

[0002] Cage locking hooks, as a common type of fastener, are widely used in animal cages, industrial equipment railings, warehouse isolation netting, and other applications requiring detachable installation and high safety standards. Their core function is to quickly and securely lock the hook components onto the cage body or frame bars, forming a stable connection or closed structure.

[0003] However, such existing technologies have certain shortcomings in practical applications. These structures generally lack effective multi-stage anti-loosening and vibration-resistant designs. Under long-term dynamic loads of impact or vibration, threaded connections are prone to gradually loosening due to fretting wear, posing safety hazards. Furthermore, the anti-slip and ergonomic considerations of the operating surface are insufficient, making it easy to slip when operating by hand, especially in wet conditions or when wearing gloves. Utility Model Content

[0004] The purpose of this invention is to provide a cage locking hook to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cage locking hook includes a hook clamp and a knob nut. The hook clamp is provided with an installation part, and the knob nut is screwed and locked onto the hook clamp through the installation part.

[0007] The outer surface of the hook and latch is provided with a mounting surface, and the mounting part is located at the center line of the mounting surface;

[0008] The mounting part includes a four-lobed threaded support block, which is arranged in a ring array to form the mounting part, and each of its periphery is provided with mounting threads.

[0009] The main body of the knob nut is a cap body, and an installation screw sleeve is provided inside the cap body. The installation screw sleeve is provided with an internal thread, and the installation screw sleeve is connected to the installation thread of the mounting part through the internal thread.

[0010] The mounting screw sleeve is surrounded by several support blocks, which support the mounting screw sleeve and the cap body.

[0011] As a further embodiment of this utility model: the outer periphery of the cap body is provided with a number of screw-in concave angles at equal angles, and there are six screw-in concave angles; the support block is connected between the mounting screw sleeve and the cap body in a radiating manner.

[0012] As a further embodiment of this utility model: friction ridges are provided on the side edge of the mounting surface, and the friction ridges are respectively located on both sides of the mounting surface.

[0013] As a further embodiment of this utility model: the inner surface of the hook and clip is provided with a plurality of engagement points, and the engagement points are provided with elastic fasteners.

[0014] As a further improvement of this utility model: the hook fastener is a snap-on structure and is provided with a hook mounting frame, and the frame edge of the hook mounting frame is provided with an engaging edge.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention employs a split-type elastic threaded connection mechanism, designing the mounting section as a multi-lobed, independent annular array of threaded support blocks. This structure imparts radial elasticity, enabling adaptive compensation for assembly tolerances and thread engagement deviations. It fundamentally avoids the seizing or stripping problems common in traditional integral threads, ensuring a tight and smooth connection between the threaded pairs. By integrating friction ribs with specific anti-slip textures and a cap with multi-angled concave corners on the outer surface, and cooperating with a snap-fit ​​mounting frame with elastic clips on the inner surface, it ensures a stable connection over long-term use. A uniquely designed radially radiating support block inside the knob nut forms a high-strength mechanical bridge between the mounting sleeve and the cap shell, evenly distributing the enormous torque and axial tension during locking, greatly enhancing the overall structural rigidity and deformation resistance. Furthermore, its multi-stage fixing mechanism enhances adaptability to cage components of different specifications and shapes.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, examples of which are shown in the drawings. In the following description relating to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or identical elements.

[0025] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Example 1, as Figures 1 to 4 As shown, this embodiment provides a basic implementation of a cage locking hook, the core components of which include a hook clamp 1 for holding onto the cage bars or frame, and a knob nut 2 for providing locking force. The hook clamp 1 is designed to have an outer surface facing the user and an inner surface facing away from the user for fitting or engaging with the target installation position.

[0028] In the central area of ​​the outer surface of the hook-and-loop fastener 1, there is a flat or slightly raised mounting surface 11. The mounting surface 11 serves as the support base for the entire locking mechanism, and multiple raised friction ribs 12 extend horizontally from its two side edges. These friction ribs 12 are arranged in parallel to provide anti-slip resistance during manual operation.

[0029] A mounting section 3 is integrally formed at the central longitudinal axis of the mounting surface 11. This mounting section 3 is not a complete tubular structure, but rather consists of four independent threaded support blocks 31 arranged in a circular array, meaning the four threaded support blocks 31 are distributed at 90-degree intervals around a common virtual central axis. Each threaded support block 31 has external threads machined on its outer arc surface, collectively forming the complete mounting thread 32 of the mounting section 3. This segmented design gives the threaded support blocks 31 a certain degree of radial elasticity.

[0030] The knob nut 2 is independent of the hook clip 1, and its main body is a cap body 21 that is easy to grip. Viewed from above, the outer contour of the cap body 21 is not a complete circle; its outer peripheral wall is cut with six inwardly recessed turning angles 22 at equal angles, forming an approximately hexagonal contour, facilitating the application of force using general tools or by hand. A mounting sleeve 23 is coaxially fixed at the center of the cap body 21. The inner wall of the mounting sleeve 23 is machined with internal threads 25 that match the mounting threads 32. To ensure the connection strength between the mounting sleeve 23 and the cap body 21 when subjected to high locking torque, multiple triangular support blocks 24 are radially connected between the outer wall of the mounting sleeve 23 and the inner top wall of the cap body 21. These support blocks 24 are evenly distributed circumferentially, effectively distributing the force on the sleeve to the entire cap body 21.

[0031] Furthermore, the hook clamp 1 has a snap-fit ​​structure, with an open or closed hook mounting frame 13 at its lower or side. The edges of this frame are bent inward to form engaging edges 14 for hooking or limiting. Multiple raised engagement points 15 are distributed on the inner surface of the hook clamp 1, each engagement point 15 connected to an elastically deformable fastener 16 for providing pre-fixation and cushioning during initial installation.

[0032] During operation, the first step is pre-installation. Align the hook mounting frame 13 of the hook clamp 1 with the target horizontal bar or frame of the cage. At the same time, the elastic buckle 16 on the inner surface will contact the surface of the cage and undergo elastic deformation, generating a certain pre-tightening force and friction, so that the hook clamp 1 can be temporarily stabilized in the preset position to prevent it from falling off.

[0033] Next, perform the final tightening. Align the mounting sleeve 23 of the knob nut 2 with the mounting portion 3 on the hook clamp 1, allowing the four-lobed threaded support block 31 to enter the mounting sleeve 23. Then, rotate the knob nut 2 clockwise. The screwing concave angle 22 on the nut body 21 provides a good point of force. During rotation, the internal thread 25 of the mounting sleeve 23 engages with the external mounting thread 32 of the threaded support block 31. As the knob nut 2 is continuously screwed in, the inner top wall of its nut body 21 will eventually press against the mounting surface 11 of the hook clamp 1. This continuous clamping force is transmitted through the body of the hook clamp 1 to the hook mounting frame 13 and its engaging edge 14, thereby firmly locking it onto the cage component. During this process, the friction ribs 12 on both sides of the mounting surface 11 effectively prevent the user's fingers from slipping.

[0034] The basic structure provided in this embodiment achieves fast, reliable, and high-strength cage locking. Installation is highly convenient; the elastic clips 16 and snap-fit ​​design enable quick pre-positioning, allowing for easy operation by a single person. The locking force is substantial and stable; the segmented elastic thread ensures maximum thread contact area and even force distribution. Combined with the radial support structure, it can withstand frequent vibrations and impacts, preventing loosening. It has strong applicability; the elastic thread design tolerates minor misalignment of the installation axis, improving the assembly success rate. The user experience is excellent; the multi-faceted cap and anti-slip ribs provide a comfortable, effortless, and non-slip tightening experience, whether by hand or with tools.

[0035] Example 2, as Figure 4 As shown, in this embodiment, based on Embodiment 1, the outer shape of the cap body 21 of the knob nut 2 is further strengthened. The depth of the six screw-in concave corners 22 is increased, making the convex corners formed between adjacent concave corners sharper and more prominent. The top surfaces of these convex corners can be knurled or scored. The top plane of the cap body 21 can also be designed with concave finger grooves or intersecting reinforcing ribs. At the same time, the area of ​​the mounting surface 11 on the hook clip 1 is appropriately increased, and the number of friction ribs 12 on both sides of its sides is increased, and the cross-sectional shape is optimized to be asymmetrical sawtooth or wavy. The extension range of the friction ribs 12 also extends beyond the mounting surface 11, partially extending to the adjacent area of ​​the outer surface of the hook clip 1. The root of the four-lobed threaded support block 31 of the mounting part 3 can be rounded to further concentrate the elastic deformation capability.

[0036] Example 3, as Figure 3As shown, based on the structure of Embodiment 1, the retaining and contact components of the hook clamp 1 are further designed. In this embodiment, the hook mounting frame 13 is adapted to the shape of common cage-like grid bars (such as round or square). The engaging edge 14 is no longer a simple right-angled fold, but has evolved into a composite structure with an arc-shaped guide surface and a multi-segmented interlocking surface. For example, it can be designed as a guide ramp connecting to an acute-angled interlocking hook. The number of interlocking points 15 on the inner surface is increased and arranged in the stress concentration area or edge position of the inner surface of the hook clamp 1 according to mechanical analysis. When the grid bar contacts the elastic buckle 16, the buckle bends elastically, and the contact head at its end will slightly "bite" into the grid bar surface or generate a large static friction force (for smooth hard materials), instantly generating a constraint force in multiple directions, achieving a preliminary stable engagement with a "click". At this time, the hook clamp 1 has no risk of falling off. Subsequently, during the final tightening process by screwing in the knob nut 2, a strong axial tightening force is transmitted through the rigid hook clamp 1 body, forcing the sharp-angled hook of the engaging edge 14 to generate a strong mechanical interlock with the grid surface.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
