Description

Technical Field

[0001] This utility model relates to a shoe heel, and more particularly to a women's shoe heel that is easy to replace. Background Technology

[0002] In existing technologies, fixed-heel women's shoes are used in various life scenarios. In formal occasions such as business meetings, dinners, or social events, women often choose stiletto heels to project elegance and professionalism, requiring attention to gait balance to maintain a proper posture. For everyday outings, such as shopping, commuting, or leisure travel, chunky heels are favored for their more stable support and reduced foot pressure, making them suitable for extended walking. Users typically pre-select heel styles based on the type of activity, making the process of putting on and taking off shoes simple and straightforward. However, once the heel is fixed, it cannot be adjusted, meaning each pair of shoes is only suitable for a single occasion, lacking flexibility. This forces women to stock multiple pairs of shoes for different needs, taking up space and increasing the complexity of their choices.

[0003] While fixed heel designs are simple and reliable, they cannot simultaneously accommodate the needs of stiletto heels for formal occasions and the preference for chunky heels for everyday wear. Users need to purchase multiple pairs of shoes to meet diverse needs, which not only increases the financial burden but also incurs storage and management costs. To address this issue, existing technology has developed plug-in heels, which consist of a main shoe body and a replaceable heel piece. The heel piece can be designed as either a stiletto or chunky heel, and the connection is achieved through a plug-in method, aiming to improve the versatility of the shoe. However, this connection method lacks structural stability and is prone to loosening or even detachment during actual use due to friction, pressure, or frequent handling. This not only affects walking safety and comfort but may also accelerate component wear, reducing the shoe's lifespan and user experience. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a women's shoe heel that is securely connected and easy to replace.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a women's shoe heel that is easy to replace, comprising a main body and a heel body, wherein the main body and the heel body are connected in a detachable manner. The main body is provided with a first buckle area and a first tenon area, and the heel body is provided with a second buckle area and a second tenon area at corresponding positions to the first buckle area and the first tenon area. The first tenon area and the second tenon area are positioned towards the rear of the heel compared to the first buckle area and the second buckle area. The main body and the heel body are detachably connected by buckles and tenons.

[0006] The beneficial effects of this utility model are as follows: By setting a composite connection structure of mortise and tenon joints and snap fasteners, this utility model cleverly combines the advantages of two connection methods, effectively improving the structural stability and reliability of replaceable heels. The mortise and tenon structure mainly bears the torque and pressure from the back of the heel during walking. Due to its excellent tensile and shear resistance, it can significantly prevent the heel from flipping backward or loosening under force. The snap fastener structure mainly provides lateral fastening force, preventing the heel from swaying left and right or separating up and down from the main body. The two work together to form a three-dimensional, multi-directional constraint, making the connection point more stable. This overcomes the problem of easy loosening and falling off of simple plug-in connections in the prior art, improves walking safety and comfort, and helps extend the service life of the heel components. As a preferred embodiment, the mortise and tenon structure can be specifically implemented by setting a tenon with an inwardly tapering interlocking bevel on the main body and a matching mortise on the heel. During installation, the tenon is inserted into the mortise, and its beveled surface fits tightly against the inner wall of the mortise. Due to the beveled surface, when subjected to backward tension, the tenon and mortise engage even more tightly, thus preventing loosening. As another preferred method, the tenon can also have a transverse boss at its end, while the bottom of the mortise has a corresponding groove. When the tenon is fully inserted, the boss engages with the groove, forming a mechanical interlock, further preventing the tenon from accidentally coming out of the mortise.

[0007] Furthermore, the first snap-fit ​​area has symmetrically arranged side plates on both sides of the main body, the side plates extending towards the heel body, and a snap-fit ​​groove formed between the two side plates. The side plates are provided with positioning holes. The second snap-fit ​​area is provided with snaps that can be inserted into the snap-fit ​​groove. At least part of the snaps protrudes outside the heel body and is submerged in the snap-fit ​​groove after engaging with it. The snaps are provided with positioning protrusions that cooperate with the positioning holes to form a fixed positioning protrusion.

[0008] The beneficial effects of this technical solution are as follows: by designing side panels, buckle slots, and concealed buckles, the connection structure becomes more streamlined and integrated in appearance. When the heel is not connected to the main body, the buckle protrudes for easy alignment and operation; after connection, the protruding part is completely submerged in the buckle slot formed by the side panels. From the outside, the side panels conceal the buckle structure, giving the heel a complete and smooth profile, enhancing the product's aesthetics. The cooperation between the positioning hole and the positioning protrusion provides a clear and reliable locking mechanism, ensuring that the buckle is securely held in the locked position after being inserted into the buckle slot, preventing accidental unlocking due to vibration or slight external force, thereby enhancing the certainty and security of the connection. As a preferred embodiment, the buckle can be designed as a component with elastic deformation capability, with the positioning protrusion located at the end of the elastic arm. During insertion into the latch slot, the elastic arm is compressed inward by the inner wall of the side plate, causing the positioning protrusion to temporarily retract. When the latch moves to the predetermined position, i.e., when the positioning protrusion aligns with the positioning hole on the side plate, the elastic arm pops outward under its own restoring force, causing the positioning protrusion to engage in the positioning hole, thus completing the locking. This design achieves one-step quick locking without the need for additional tools.

[0009] Furthermore, the buckle is provided with at least two symmetrically arranged locking pins on both sides of the buckle, and the locking pins on both sides are provided with positioning protrusions. The locking pins on both sides have elasticity that can be retracted towards the center of the buckle or popped outward from the center of the buckle.

[0010] The beneficial effects of this technical solution are as follows: The clearly defined locking posts with specific elasticity and structural distribution make the extension and retraction of the positioning prongs more reliable and controllable. The symmetrically arranged locking posts provide balanced elastic restoring force, ensuring that the positioning prongs on both sides can synchronously and stably spring into the positioning holes, avoiding problems such as weak connections or misalignment due to unilateral failure. The elastic design of the locking posts is the core of achieving tool-free and convenient assembly and disassembly. It allows users to directly press the base during installation, using elastic deformation to lock it in place; during disassembly, pressing the locking post towards the center (or using other triggering mechanisms) will cause it to retract, thereby releasing the locking of the positioning prongs to the positioning holes and achieving rapid separation. As a preferred embodiment, the locking posts can be integrally injection molded from engineering plastics (such as polyoxymethylene, nylon, etc.) with good elasticity and fatigue strength. The connection between the base and the buckle body is designed as a thin, flexible hinge area, while the main body of the locking post is an arm-shaped structure with a certain thickness and strength. When subjected to an inward squeezing force, the flexible hinge area bends and deforms, causing the entire locking post to retract towards the center; after the external force is removed, the flexible hinge area returns to its original shape due to the elasticity of the material, driving the locking post to pop outward.

[0011] Furthermore, it also includes a snap-fit ​​post located at the center, which is provided with a snap-fit ​​groove, and a snap-fit ​​protrusion corresponding to the snap-fit ​​groove is provided in the snap-fit ​​groove.

[0012] The beneficial effects of this technical solution are as follows: The addition of a complementary engagement structure of a snap-fit ​​groove and a snap-fit ​​protrusion in the central area of ​​the snap-fit ​​structure provides multiple positive benefits. First, during assembly, the snap-fit ​​protrusion within the snap-fit ​​groove guides the groove's insertion, acting like a guide rail, allowing the snap-fit ​​to align more accurately and smoothly into the groove, reducing assembly difficulty and facilitating blind operation. Second, after the connection is locked, the interlocking of the snap-fit ​​protrusion and the snap-fit ​​groove increases the contact area and mechanical interlocking points between the snap-fit ​​and the groove. Particularly in the plane perpendicular to the insertion direction, it provides anti-torsional and anti-sway constraints, significantly enhancing the connection stiffness and overall stability, making the composite connection structure more robust. As a preferred design, the snap-fit ​​protrusion can be designed as a trapezoidal prism with guide bevels on both sides and a flat top. The corresponding snap-fit ​​groove is a matching trapezoidal recess. During the initial insertion, the guide slope of the snap-fit ​​protrusion contacts the entrance edge of the snap-fit ​​groove, automatically correcting minor alignment deviations and guiding the snap-fit ​​protrusion into the snap-fit ​​groove to achieve self-alignment.

[0013] Furthermore, the buckle is provided with a spring hole, and a spring is provided in the spring hole. The two ends of the spring are respectively connected to the snap-fit ​​posts located on both sides, so that it has or enhances the elasticity of retracting towards the center of the buckle.

[0014] The beneficial effects of this technical solution are as follows: by introducing a spring as an independent elastic element, a stronger, more controllable, and more durable elastic force is provided for the retraction movement of the locking pins. Compared to a design that relies entirely on the elasticity of the locking pin material itself, the addition of a spring ensures that even when the locking pin material undergoes slight plastic deformation or elastic decay due to long-term use or changes in ambient temperature, it still provides a stable and reliable elastic reset function, thereby extending the service life and reliability of the locking mechanism. Furthermore, the spring's elastic characteristics (such as the spring constant) can be precisely selected and designed as needed, making the required pressing force during unlocking more moderate, ensuring both a secure connection and easy disassembly. As a preferred embodiment, the spring hole can extend laterally through the locking body, with its two ends opening to the inner walls of the two locking pins respectively. A compression spring is placed horizontally inside the spring hole, with its two ends abutting against the protrusions on the inner sides of the two locking pins respectively. In its natural state, the preload of the spring causes the two locking pins to tend to converge toward the center; when unlocking is required, the locking pins are pressed from the outside to overcome the spring force and make them converge further; after being released, the spring force pushes the locking pins to reset and pop out.

[0015] Furthermore, the buckle is symmetrically provided with first fastening holes on both sides of its center line, and the second buckle area is provided with a second fastening hole corresponding to the first fastening hole, which can be spliced ​​with it. The buckle and the heel body are detachably fixed by fasteners passing through the first fastening hole and the second fastening hole.

[0016] The beneficial effects of this technical solution are as follows: designing the buckle as a detachable, independent component from the heel body greatly improves the product's maintainability and modularity. When the buckle is damaged due to long-term use, accidental damage, or requires upgrading, it is not necessary to replace the entire heel body; simply unscrew the fasteners to remove the old buckle module and replace it with a new one, reducing maintenance costs. The symmetrically arranged first and second fastening holes ensure that the buckle is evenly and firmly fixed to the heel body, preventing it from loosening or shifting during use, ensuring the reliability of the connection between the buckle mechanism and the heel body, and thus ensuring the long-term stable operation of the entire heel replacement system. As a preferred embodiment, the fasteners can be miniature screws. The first fastening hole is a through hole penetrating the buckle body, and the second fastening hole is a threaded blind hole located on the internal support structure of the heel body shell. When installing the buckle, place the buckle in the predetermined position of the second buckle area, aligning its first fastening hole with the second fastening hole of the heel body. Then, screw in the micro screw from the outside of the buckle. After the screw passes through the first fastening hole, it is screwed into the thread of the second fastening hole, thereby tightening and fixing the buckle to the heel body.

[0017] Furthermore, a tenon is provided in the first mortise and tenon area, and a mortise is provided in the second mortise and tenon area. The tenon and the mortise are provided with matching bevels, and the bevels on the tenon are wrapped inside the mortise after they are matched.

[0018] The beneficial effects of this technical solution are as follows: it concretizes the structural form of mortise and tenon connections, and greatly optimizes the mechanical properties between the tenon and the mortise by setting mutually cooperating bevels. The bevels effectively decompose the loads perpendicular or inclined to the connection surface (especially the tensile force from behind the heel) into normal pressure perpendicular to the bevel and frictional force along the bevel inward. This decomposition and transformation of force gives the connection a "self-tightening" effect when under tension, that is, the greater the tensile force, the tighter the tenon and mortise engage, thus reliably resisting the tendency of the heel and body to separate. The design of the tenon being wrapped inside the mortise protects the interlocking contact surface, reducing the possibility of external dust and dirt intruding and affecting the joint accuracy. It also allows external forces to be transmitted more evenly to the tenon through the mortise wall, resulting in high connection strength and good stability. As a preferred embodiment, the tenon can be designed as a dovetail-like structure, with interlocking bevels on both sides that gradually widen from the heel towards the end. The corresponding mortise is a dovetail groove that precisely matches it. Once the tenon is inserted into the dovetail groove, its two beveled sides fit perfectly against the inner beveled side of the groove, forming a large surface contact area. Any attempt to pull the tenon out from behind will cause the two beveled sides to press even tighter, dramatically increasing the friction and thus achieving a secure lock.

[0019] Furthermore, the tenon protrudes outward from the heel and has an interlocking platform, and the bottom of the mortise has a connecting slot corresponding to the interlocking platform.

[0020] The beneficial effects of this technical solution are as follows: Adding an interlocking platform and a corresponding connecting slot to the tenon end creates another layer of mechanical locking protection on top of the beveled interlocking. The engagement of the interlocking platform and the connecting slot forms an interlocking structure similar to a "hook" or "step." When the tenon is fully inserted into the mortise, the interlocking platform enters and locks into the connecting slot. At this point, if subjected to a backward pulling force, the side of the interlocking platform will directly contact and abut against the inner wall of the connecting slot, bearing the main tensile force. This purely mechanical rigidity effectively prevents the tenon from coming out of the mortise, greatly improving the tensile strength of the connection. This structure works in conjunction with the beveled interlocking surface, which provides continuous pre-tightening and friction locking, while the interlocking platform provides final rigid protection. This dual protection ensures the absolute reliability of the mortise and tenon connection under extreme stress conditions. As a preferred embodiment, the interlocking platform can be a rectangular or trapezoidal protrusion extending backward from the center of the tenon end face. The connecting slot is a blind hole or through groove located at the bottom of the mortise, with a shape matching the interlocking platform. In the final stage of assembly, once the beveled portion of the tenon is fully inserted into the mortise, the interlocking plate precisely embeds into the connecting slot, accompanied by a clear "click" feel or sound, indicating to the user that the connection is fully in place and locked.

Detailed Implementation

[0022] This utility model embodiment provides a women's shoe heel that is easy to replace, such as... Figure 1-12 As shown: It includes a main body 1 and a heel body 2. The main body 1 is the part that is fixedly connected to the sole, and the heel body 2 is the part that contacts the ground. The two are connected in a detachable manner, so that users can replace the heel body 2 with different heights or styles as needed.

[0023] Specifically, a first snap-fit ​​area 11 and a first tenon-and-mortise area 12 are provided on the mating surface of the main body 1 facing the heel body 2. Correspondingly, a second snap-fit ​​area 21 and a second tenon-and-mortise area 22 are provided on the mating surface of the heel body 2 facing the main body 1. To achieve better mechanical support, the first tenon-and-mortise area 12 and the second tenon-and-mortise area 22 are positioned closer to the rear of the heel (i.e., towards the heel when worn) than the first snap-fit ​​area 11 and the second snap-fit ​​area 21. The main body 1 and the heel body 2 are detachably connected through a combination of a tenon-and-mortise connection at the rear and a snap-fit ​​connection at the front. This layout utilizes the characteristic that the tenon-and-mortise structure can withstand a larger bending moment than the snap-fit ​​structure, placing the main stress-bearing part (tenon-and-mortise) at the heel position, which is prone to backward bending moment, effectively preventing unstable connection or loosening between the heel body 2 and the main body 1 under stress.

[0024] Within the first mortise and tenon area 12, an outwardly protruding tenon 121 is provided. Within the second mortise and tenon area 22, an inwardly recessed mortise 221 is provided, the shape of which matches the tenon 121 for insertion. To enhance the tightness and guidance of the connection, matching bevels are provided on the mating surfaces of the tenon 121 and the mortise 221. When the tenon 121 is inserted into the mortise 221, its bevels will fit tightly against the bevels of the mortise 221, and the entire tenon 121 will be enclosed within the mortise 221. Furthermore, to improve the resistance to pull-out, a protruding engagement platform 1211 is provided on the end face of the tenon 121 facing the rear of the heel. Correspondingly, a recessed connecting slot 2211 is provided at the bottom (i.e., the deepest point) of the mortise 221. During assembly, the engagement plate 1211 is inserted into the connection slot 2211 to form an additional mechanical interlock, thereby further increasing the stability of the connection.

[0025] Within the first snap-fit ​​area 11, side plates 111 are symmetrically arranged on both sides of the main body 1, both extending towards the heel body 2. A snap-fit ​​groove 112 opening towards the heel body 2 is formed between the two side plates 111. A positioning hole 113 is provided on each side plate 111. Within the second snap-fit ​​area 21, a snap-fit ​​211 is provided. This snap-fit ​​211 is provided with at least two snap-fit ​​posts 2111, which are symmetrically arranged on both sides of the snap-fit ​​211. The position and size of the snap-fit ​​posts 2111 are designed to be able to be inserted into the snap-fit ​​groove 112 formed by the two side plates 111. In the initial state (i.e., before insertion into the snap-fit ​​slot 112), at least part of the snap-fit ​​post 2111 protrudes beyond the mating plane of the body 2. When the snap-fit ​​211 and snap-fit ​​slot 112 are fully engaged, this protruding part disappears into the internal space of the snap-fit ​​slot 112, resulting in a minimal gap at the joint when viewed from the outside, leading to a more integrated and streamlined appearance. Positioning protrusions 21111 are provided on the snap-fit ​​posts 2111 on both sides of the snap-fit ​​211, their positions corresponding to the positioning holes 113 on the side plate 111. The snap-fit ​​posts 2111 on both sides are elastic, allowing them to retract towards the center of the snap-fit ​​211 or pop out away from the center. This elasticity can come from the elastic deformation capability of the material used to make the snap-fit ​​posts 2111 (such as plastic or metal with a certain degree of toughness). To achieve a more reliable and easily controllable elastic reset, a spring hole 2112 can be provided on the snap fastener 211, and a spring 2113 can be installed in the spring hole 2112. The two ends of the spring 2113 are respectively connected to the snap-fit ​​posts 2111 located on both sides, thereby providing or reinforcing the snap-fit ​​posts 2111 with an elastic force that pulls them towards the center of the snap fastener. At the center of the snap fastener 211 (i.e., between the two snap-fit ​​posts 2111), a central snap-fit ​​post 2114 can also be provided, on which a snap-fit ​​groove 2116 can be formed. Correspondingly, a snap-fit ​​protrusion 1121 that mates with the snap-fit ​​groove can be provided in the snap-fit ​​groove 112 of the main body 1. The engagement between the central locking post 2114 and the protrusion in the locking groove 112 serves to guide the precise insertion of the locking buckle 211 into the locking groove 112, preventing misalignment, and also enhances the overall connection between the locking buckle 211 and the locking groove 112. Furthermore, to facilitate maintenance or replacement of the locking buckle 211, first fastening holes 2115 are symmetrically arranged on both sides of its center line. On the heel body 2 structure within the second locking area 21, second fastening holes 212 are provided corresponding to the first fastening holes 2115. The locking buckle 211 can be detachably fixed to the heel body 2 by fasteners such as screws passing through the aligned first fastening holes 2115 and second fastening holes 212.

[0026] The working principle and assembly method of this embodiment are as follows: When the heel body 2 needs to be installed, first align the mortise 221 on the heel body 2 with the tenon 121 on the main body 1, and insert the tenon 121 into the mortise 221. During this process, the engagement platform 1211 of the tenon 121 will slide into the connecting slot 2211 at the bottom of the mortise 221, completing the pre-positioning of the mortise and tenon connection. During this process, the buckle 211 on the heel body 2 will be aligned with the buckle groove 112 on the main body 1 and inserted. During the insertion process, the positioning protrusions 21111 on the two sides of the buckle 211 will first contact the inner side of the side plate 111. Under the pressure of the side plate 111, the elastic buckle 2111 will retract towards the center of the buckle 211, thereby retracting the positioning protrusions 21111, allowing the buckle 2111 to slide smoothly into the buckle groove 112. When the locking pin 2111 slides to the position of the positioning hole 113, the locking pin 2111, no longer pressed by the side plate 111, quickly pops outward under the elasticity of its own material or the action of the spring 2113, causing the positioning protrusion 21111 to engage in the positioning hole 113. At the same time, the entire buckle 211 is inserted into the buckle groove 112. A clear "click" sound will be heard, indicating that the buckle is in place. At this point, the main body 1 and the base body 2 are firmly connected together through the mortise and tenon interlock at the rear and the buckle lock at the front. When it is necessary to disassemble and replace the base body 2, the operator can use their fingers or tools to simultaneously press the parts of the locking pins 2111 on both sides of the buckle 211 that are exposed outside the positioning hole 113 (i.e., the exposed positioning protrusions 21111), forcing the locking pin 2111 to retract towards the center again, causing the positioning protrusions 21111 to exit from the positioning hole 113. Then, pull out the rear end of the heel body 2 to the rear, so that the engagement platform 1211 of the tenon 121 disengages from the connecting slot 2211, thereby separating the heel body 2 from the main body 1 and completing the disassembly.

[0027] The spring configuration of the latch 211 is as follows: the latching posts 2111 on both sides are integrally formed with the latch 211. The spring 2113 is a tension spring and is sleeved on the screw post 2117 used to position the spring 2113. The two ends of the spring 2113 are respectively latched on the latching posts 2111 on both sides to enhance the elasticity of the latching posts 2111 on both sides retracting towards the center of the latch 211.

[0028] The spring configuration of the latch 211 is as follows: the latching posts 2111 on both sides are inserted into the spring holes 2112 and fixed to the latch by fasteners. Each latching post 2111 has a connecting post 2118 facing the center of the spring hole 2112. The two ends of the spring 2113 are fixed to the connecting posts 2118 respectively to enhance the elasticity of the latching posts 2111 on both sides retracting towards the center of the latch 211.

[0029] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
