Description

Technical Field

[0001] This utility model relates to the field of bag and clothing accessories technology, specifically to a wear-resistant foot spike and a molding die. Background Technology

[0002] Luggage feet are components of luggage, installed on the bottom to protect the bottom surface from wear and damage when in contact with the ground, and to assist in gliding or securing the luggage. Existing feet are mostly made of single materials such as plastic or metal. When using plastic feet, the surface is prone to scratches and wear from long-term friction, leading to structural damage and significantly shortening its lifespan. When using metal feet, long-term friction can damage the overall appearance, causing discoloration and easy oxidation and corrosion. Furthermore, the use of hard materials means that when the luggage hits the ground, it is prone to impact and vibration, lacking necessary cushioning. This vibration is transmitted to the user when the luggage travels on bumpy surfaces, resulting in a poor user experience. Hard materials also generate noise when in contact with tabletops, further complicating comfort. Therefore, there is a need for a type of foot for the bottom of luggage that is wear-resistant and provides cushioning, solving the problems of poor wear and corrosion resistance, poor shock absorption, and excessive noise during use. Utility Model Content

[0003] One of the purposes of this utility model is to provide a wear-resistant foot nail that solves the problems of poor wear and corrosion resistance, poor shock resistance, and high noise of existing foot nails.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A wear-resistant spike includes a spike body, a wear-resistant sleeve, and a connecting post. The wear-resistant sleeve is disposed on one end of the spike body, and the connecting post is disposed on the other end of the spike body. A protrusion is provided on the lower end of the spike body, and the two side walls of the protrusion extend outward to form a buckle. The protrusion is embedded in the wear-resistant sleeve, and the buckle and the wear-resistant sleeve are engaged. The buckle extends deep into the wear-resistant sleeve to form a snap-fit. The wear-resistant sleeve is a non-metallic sheath, which improves the mechanical strength of the connection and also enhances the shock absorption capacity.

[0006] Furthermore, one end of the nail body is provided with an annular groove, which is arranged to surround the connecting post. At least one through hole is provided on the bottom surface of the annular groove, and at least one through hole penetrates the nail body, thereby reducing the mass of the nail body and absorbing the impact transmitted from the ground to a certain extent.

[0007] Preferably, the connecting post is provided with internal threads for connection to the fabric.

[0008] Preferably, a connector is also included, which passes through the fabric and connects to the internal thread, providing a secure connection that is not easily damaged.

[0009] Even better, the edge of the wear-resistant sleeve is flush with the outer contour of the nail body, which is aesthetically pleasing and easy to replace.

[0010] As an even better feature, the top of the wear-resistant sleeve is designed in a hemispherical shape, making it suitable for use in mobile bags.

[0011] As a better option, the top of the wear-resistant sleeve is designed in a columnar shape, which is suitable for fixed placement and use.

[0012] Even better, the wear-resistant sleeve is made of PET, which has wear-resistant and oil-resistant properties and low usage cost.

[0013] The second objective of this utility model is to provide a foot nail forming mold that solves the problem of difficulty in repairing existing foot nails after they have worn down.

[0014] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0015] A foot spike molding mold includes the wear-resistant foot spike and a molding plate. The molding plate has a recessed portion, and the side wall of the spike abuts against the inner wall of the recessed portion. A molding cavity for molding the wear-resistant sleeve is provided between the bottom of the spike and the bottom surface of the recessed portion. This mold is used to quickly repair damaged foot spikes. The foot spikes have low operating costs and are easy to maintain.

[0016] Preferably, the top of the nail body is flush with the upper surface of the molding plate, which reduces the difficulty of molding the wear-resistant sleeve.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The wear-resistant foot nail is provided with a nail body. The protrusion at the end of the nail body and the buckles extending laterally on both sides form a snap-fit ​​structure with the wear-resistant sleeve, which effectively enhances the mechanical locking force between the wear-resistant sleeve and the nail body, and prevents the wear-resistant sleeve from loosening and falling off under long-term friction or impact. The wear-resistant sleeve has a certain hardness and elasticity, which can improve the service life. At the same time, it can absorb the impact force of the bag contacting the ground, play a shock-absorbing role, improve the shock resistance performance, and reduce the noise during use.

[0019] (2) The wear-resistant foot nail has a ring groove and a through hole at the upper end of the nail body, which reduces the overall weight of the foot nail and allows the nail body to be fixed to the external fabric through the through hole. With the internal thread of the connecting column, it can be used to fit standard connectors such as screws, ensuring the connection strength between the foot nail and the bag, while simplifying the installation steps and improving assembly efficiency.

[0020] (3) The recessed part of the foot nail molding mold is designed to abut against the nail sidewall, forming a molding cavity between the bottom of the nail body and the mold. Glue is injected into the molding cavity through the through hole, and the wear-resistant sleeve is directly molded from the molding cavity, ensuring a seamless fit between the wear-resistant sleeve and the nail body during injection molding. The mold supports customization of the top of the wear-resistant sleeve into a hemispherical or cylindrical shape to adapt to the wear-resistant requirements of different scenarios. It can be quickly replaced after the wear-resistant sleeve is damaged, and the connection strength after molding is high. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] Example 1

[0031] like Figures 1-6As shown, this embodiment discloses a wear-resistant nail, including a nail body 1, a wear-resistant sleeve 2, and a connecting post 12. The wear-resistant sleeve 2 is disposed on one end of the nail body 1, and the connecting post 12 is disposed on the other end of the nail body 1. A protrusion 13 is provided on the lower end of the nail body 1. The side wall of the protrusion 13 extends outward to form a buckle 131. Specifically, the two side walls of the protrusion 13 extend laterally to form the buckle 131, or the outer wall of the protrusion 13 extends into a ring-shaped buckle 131. The protrusion 13 is embedded into the wear-resistant sleeve 2. Inside, the buckle 131 and the wear-resistant sleeve 2 are engaged. The wear-resistant sleeve 2 is a non-metallic protective sleeve, specifically a plastic or rubber protective sleeve, which can effectively enhance the mechanical locking force between the wear-resistant sleeve 2 and the nail body 1, preventing the wear-resistant sleeve 2 from loosening and falling off under long-term friction or impact. The buckle 131 and the nail body 1 have a certain shock absorption capacity. In addition, the wear-resistant sleeve 2 has a certain hardness and elasticity, which can absorb the impact force of the bag contacting the ground, improve service life and user experience.

[0032] Among them, the wear-resistant sleeve 2 is a non-metallic protective sleeve, specifically made of plastic or rubber, which improves the corrosion caused by the damage to the surface anti-rust layer of existing metal spikes, thus enhancing wear resistance and corrosion resistance.

[0033] Preferably, the diameter of the protrusion 13 is smaller than the diameter of the nail body 1, so that the buckle 131 on the nail body 1 forms a groove that is recessed towards the center of the nail body 1, which increases the contact area and depth between the nail body 1 and the wear-resistant sleeve 2, thereby improving the connection strength between the two.

[0034] Furthermore, a ring groove 16 is provided on one end of the nail body 1. The ring groove 16 is arranged to surround the connecting post 12. At least one through hole 11 is provided on the bottom surface of the ring groove 16. The at least one through hole 11 penetrates the nail body 1. The through hole 11 is used for injection molding of the wear-resistant sleeve 2. The ring groove 16 can prevent the injection of glue from overflowing and reduce the use of materials, reduce the weight of the nail body 1, and improve the comfort of using the bag. The through hole 11 is used as an injection port. The wear-resistant sleeve 2 forms an integral structure with the nail body 1 through secondary molding by injection of glue, so that the bonding strength between the nail body 1 and the wear-resistant sleeve 2 is higher.

[0035] Preferably, the connecting post 12 is provided with an internal thread 14, which is used for connecting bags and suitcases, making it convenient for disassembly, assembly, and replacement.

[0036] More preferably, the top of the protrusion 13 is set in an arc shape, and the arc shape tapers from the middle high point to both sides, so that the impact of the foot spike contacting the ground is transmitted to both sides after passing through the wear-resistant sleeve 2, reducing the direct upward transmission of vibration and thus improving the comfort of use.

[0037] More preferably, it also includes a connector 4, which passes through the fabric 5 and is connected to the internal thread 14. The connector 4 is a large flat head bolt, which increases the diameter of the head and increases the contact area with the fabric 5, thereby improving the connection strength between the connector 4 and the bag, and is less likely to damage the bag fabric 5, resulting in a high aesthetic appeal.

[0038] More preferably, the edge of the wear-resistant sleeve 2 is flush with the outer contour of the edge of the nail body 1, which is aesthetically pleasing and makes it easy to replace the wear-resistant sleeve 2 later.

[0039] More preferably, the top of the wear-resistant sleeve 2 is set in a hemispherical shape, which has a small contact area and strong vibration absorption capacity, making it convenient to assist in sliding on the ground.

[0040] More preferably, the top of the wear-resistant sleeve 2 is designed in a columnar shape, which increases the contact area with the ground so that it can be placed on an inclined surface, making it easier to use.

[0041] More preferably, the wear-resistant sleeve 2 is made of PET, which has good mechanical properties, impact strength, flexural strength, and oil resistance. Its heat resistance is not high, its heat distortion temperature is low, and the equipment requirements for remolding after damage are low, making it easy to maintain.

[0042] Example 2

[0043] like Figure 3-6 As shown, this embodiment also discloses a foot nail forming mold, including a wear-resistant foot nail and a forming plate 3. The forming plate 3 is provided with a recessed portion 15. The side wall of the nail body 1 abuts against the inner wall of the recessed portion 15. A forming cavity 17 for forming a wear-resistant sleeve 2 is provided between the bottom of the nail body 1 and the bottom surface of the recessed portion 15. The forming cavity 17 has the same shape as the wear-resistant sleeve 2 and is used for quick maintenance of the foot nail to replace the wear-resistant sleeve 2.

[0044] Preferably, the top of the nail body 1 is flush with the upper surface of the molding plate 3. After the nail is put into the mold, an upper cover plate can be added to press the nail into the mold, preventing it from shaking when injection molding into the molding cavity 17 and improving the dimensional accuracy of the molded wear-resistant sleeve 2.

[0045] The process of using this foot nail forming mold is as follows:

[0046] When repairing the feet, use tools to remove the feet from the bag 6 and peel off the wear-resistant sleeve 2 on the protrusion 13. Clean the feet, then place the nail body 1 on the mold, so that the protrusion 13 falls into the molding cavity 17 of the mold, and the outer edge of the nail body 1 abuts against the outlet edge of the molding cavity 17. Then, use an injection molding tool to inject flowing plastic into the molding cavity 17 through the through hole 11 until the molding cavity 17 is filled. After initial cooling, remove the nail body 1 and let it cool completely outside. Repeat the above steps to replace each foot on the bag in turn.

[0047] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
