Description

Technical Field

[0001] This utility model relates to the field of mannequin display accessories, and more specifically to a mannequin heel protection iron structure that is easy to guide. Background Technology

[0002] The existing protective iron structure is composed of a triangular pyramid (a) and a concave body (b). The top surface of the triangular pyramid is connected to the concave body, and the diameter of the top surface is smaller than the diameter of the bottom surface. The side surface is provided with mounting screw holes for fixing the support rod (the support rod is used to support the mannequin). One side of the concave body is open (set on the same side as the mounting screw hole), and the other side is closed and is provided with fixing screw holes (for fixing the entire structure to the heel of the mannequin). The structure has significant operational defects in actual use: after the concave body is installed on the heel of the mannequin through the fixing screw hole of the closed surface, the operator needs to align the support rod with the opening (guide) of the concave body to guide it into the mounting screw hole of the triangular pyramid to complete the fixation. However, due to the small size of the guide and its rectangular design, the narrow space of the guide makes it difficult for the operator to quickly position and align it, and the angle needs to be adjusted repeatedly to find the correct insertion position. On the other hand, the edge of the rectangular guide port is prone to contact with the outer edge of the support rod during the insertion process, which obstructs the insertion process and requires additional adjustment of the direction to continue pushing, seriously affecting the efficiency and convenience of the support rod installation. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the support rod is difficult to position and easily introduced in the existing protective iron structure technology. This utility model provides a protective iron structure for mannequin heels that is easy to guide and convenient to introduce.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes an easy-to-guide mannequin heel protection iron structure, including a concave body with a triangular pyramid integrated with the concave body. The guide opening of the concave body is also provided with a flared guide frame, which is used to expand the entrance area of ​​the guide opening and guide the insertion of the support rod.

[0005] As a preferred embodiment of this utility model, the left side of the trumpet-shaped inlet frame is an open surface, and the right side is a closed surface; The opening face of the trumpet-shaped import frame and the opening face of the concave body are set on the same side; The closed surface of the trumpet-shaped inlet frame is parallel to and on the same side as the closed surface of the concave body; The top and bottom of the horn-shaped import box are symmetrically arranged to resemble a horn. The top surface of the triangular pyramid is connected to the concave body. The diameter of the top surface is smaller than the diameter of the bottom surface, and the side surface is provided with mounting screw holes for fixing the support rod (the support rod is used to support the mannequin). One side of the concave body is open (set on the same side as the mounting screw hole), and the other side is closed and is provided with fixing screw holes (used to fix the whole structure to the heel of the mannequin).

[0006] As a preferred embodiment of this utility model, the upper and lower parts of the opening surface of the concave body are provided with sliding grooves; Several I-shaped sliding columns are slidably connected inside the sliding groove (the I-shaped sliding columns can slide inside the sliding groove via sliding balls). The I-shaped sliding column is used to assist the support rod in sliding along the sliding groove.

[0007] As a preferred technical solution of this utility model, the inclination angle of the upper and lower surfaces of the trumpet-shaped guide frame is 30-45°.

[0008] As a preferred embodiment of this utility model, the concave body and the horn-shaped guide frame are integrated or welded together.

[0009] As a preferred embodiment of this utility model, the inner surface of the trumpet-shaped guide frame is magnetically set.

[0010] The beneficial effects of this utility model are as follows: This invention, by adding a trumpet-shaped guide frame, significantly reduces the difficulty of initial alignment of the support rod by increasing the entrance area. At the same time, the shape guidance function brings the support rods from scattered positions to the center of the guide, achieving the effects of rapid positioning, easy guidance, and convenient import.

[0013] like Figures 1 to 2 As shown, this utility model proposes: an easy-to-guide mannequin heel protection iron structure, including a concave body with a triangular pyramid integrated with the concave body, and a flared guide frame provided at the guide opening of the concave body. The flared guide frame is used to expand the entrance area of ​​the guide opening and guide the insertion of the support rod (for mannequin support). The structure ensures overall rigidity through the integrated design of the triangular pyramid (supporting and fixing the main body) and the concave body (the basic structure connecting the model), while the addition of the flared guide frame specifically solves the problem of "difficulty in finding" caused by the narrow guide opening in the existing technology: the enlarged entrance area of ​​the flared guide frame significantly reduces the difficulty of initial alignment of the support rods, and at the same time, the shape guidance function brings the support rods from scattered positions to the center of the guide opening, achieving the effects of rapid positioning, easy guidance and convenient import.

[0014] As a preferred embodiment of this utility model, the left side of the trumpet-shaped inlet frame is an open surface, and the right side is a closed surface; The open end, serving as the entry point of the support rod, is directly exposed to the external space, facilitating external observation and adjustment of the support rod's position by operators. The closed end, in conjunction with the closed end of the concave body, forms a "front-open, rear-closed" guide channel, preventing the support rod from shifting from the rear and ensuring the directionality of the guide path. The opening face of the trumpet-shaped import frame and the opening face of the concave body are set on the same side; The same-side setting keeps the insertion path of the support rod straight, avoiding the problem that the support rod needs to be adjusted in angle to enter the concave guide due to misalignment of the opening surface, reducing extra operation steps in the insertion process and improving the continuity of the path. The closed surface of the trumpet-shaped inlet frame is parallel to and on the same side as the closed surface of the concave body; The parallel design ensures that the forces on both are in the same direction, avoiding structural stress concentration caused by angular deviation (such as deformation or breakage that may occur after long-term use); the same-side setting makes the fixing screw hole of the closed surface (used to connect the mannequin's heel) coincide with the structural center of gravity of the flared guide frame, enhancing the overall installation stability and making it easier for the installation screws to be screwed into the fixing screw hole smoothly. The top and bottom of the horn-shaped import box are symmetrically arranged to resemble a horn. The tilted and symmetrical trumpet-shaped structure forms a natural guide slope, similar to the "convergence" principle of a funnel. When the support rod approaches the guide from any angle, the tilted top and bottom surfaces will gradually correct the lateral offset of the support rod to the central axis through physical contact, thereby transforming the "small-range positioning" that originally required precise alignment into "large-range guidance", which greatly reduces the difficulty of alignment. The top surface of the triangular pyramid is connected to the concave body. The diameter of the top surface is smaller than the diameter of the bottom surface, and the side surface is provided with mounting screw holes for fixing the support rod (the support rod is used to support the model). The design of the top diameter being smaller than the bottom diameter creates a tapered structure, which not only enhances the structural strength at the connection between the triangular pyramid and the concave body (the larger bottom diameter can distribute the force), but also guides the support rod towards the mounting screw hole through the tapered shape (similar to the guiding effect of a mortise and tenon structure); the mounting screw hole on the side provides the final fixed position for the support rod, ensuring that the supporting force is stably transmitted to the model through the triangular pyramid; One side of the concave body is open (set on the same side as the mounting screw hole), and the other side is closed and has a fixing screw hole (used to fix the whole structure to the heel of the mannequin). The opening is set on the same side as the mounting screw hole, so that the insertion path of the support rod is directly aligned with the mounting screw hole, avoiding bending or angle adjustment; the fixing screw hole on the closed surface is used to connect the entire protective iron part to the mannequin's heel with bolts and other connectors, ensuring the overall stability of the support system and preventing the risk of the mannequin tipping over due to loose connection.

[0015] As a preferred technical solution of this utility model, the upper and lower parts of the opening surface of the concave body are provided with sliding grooves; the sliding grooves provide a moving track for the subsequent I-shaped sliding column, and their positions (upper and lower parts of the opening surface) are perpendicular to the insertion direction of the support rod, which can constrain the support rod from the upper and lower sides and prevent it from shifting up and down during the insertion process. Several I-shaped sliding columns are slidably connected within the sliding groove (the I-shaped sliding columns can slide within the sliding groove via sliding balls); this allows the I-shaped sliding columns to move freely with the insertion direction of the support rod, dynamically adjusting the guide position; The I-shaped sliding column is used to assist the support rod in sliding along the sliding groove. When the support rod contacts the I-shaped sliding column, the I-shaped sliding column will slide synchronously with the direction of the support rod's advance (similar to a pulley on a track). The radial offset of the support rod is offset by the dynamic adjustment of the contact point, thereby transforming the "blocking" that may occur with the guide edge into "smooth sliding", which significantly improves the smoothness of the insertion process.

[0016] The inclination angle of the upper and lower surfaces of the trumpet-shaped guide frame is 30-45°. When the angle is less than 30°, the inclination surface is too gentle and the guiding effect is not obvious (the support rod still needs a large offset to be corrected). When the angle is greater than 45°, the inclination surface is too steep, which may lead to excessive contact stress between the support rod and the inclination surface (easy wear). The inclination angle of 30-45° can effectively converge the support rod and control the contact stress within a reasonable range.

[0017] The concave body and the horn-shaped guide frame are either integrally formed or welded together.

[0018] The inner surface of the horn-shaped guide frame is magnetically set; the magnetic inner surface (such as embedding a permanent magnet or coating a magnetic coating) can generate a weak attraction force on the metal support rod. When the support rod deviates slightly, the magnetic force will pull it back to the central axis, similar to the "self-alignment" function of a magnetic levitation rail, which further reduces the need for manual adjustment and makes the insertion process more automated.
