Description

Technical Field

[0001] This utility model relates to a folding anti-pinch structure for a skateboard. Background Technology

[0002] Traditional skateboard folding structures typically employ a one-piece connection, a design that is quite common, while skateboards with folding connection structures are relatively rare. Although some skateboards do incorporate folding structures, these designs often fail to adequately address the potential for fingers or objects to be caught during folding. Particularly at the hinge joints of the folding surfaces, fingers, clothing, or other small items are highly susceptible to accidental trapping, potentially causing injury to the user and damage to belongings. Furthermore, traditional folding structures are relatively weak in terms of safety protection, often lacking effective safety mechanisms and relying primarily on the user's heightened attention to avoid being caught. However, this design approach, dependent on the user's subjective attention, clearly poses certain safety risks and fails to fundamentally guarantee a safe user experience. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model proposes a folding anti-pinch structure for skateboards, which can not only ensure safety during the folding process, but also improve the convenience of use.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A folding anti-pinch structure for a skateboard includes a first folding plate, a second folding plate connected to the first folding plate via a hinge, a spring telescopic structure disposed within the first folding plate, and a limiting slot disposed at the folding surface of the second folding plate. The spring telescopic structure includes a spring ejection structure disposed within the first folding plate and a telescopic protrusion disposed within the first folding plate that protrudes outward via the spring ejection structure and cooperates with the limiting slot.

[0006] Preferably, a folding hinge is provided on one side of the first folding plate and the second folding plate. One end of the folding hinge is fixed to the first folding plate with screws, and the other end is fixed to the second folding plate with screws.

[0007] Preferably, the spring ejection structure includes two spring mounting posts inserted into the first folding plate, spring insertion holes opened on the spring mounting posts, and compression springs inserted into the spring insertion holes.

[0008] Preferably, the spring mounting post is inserted into the first folding plate and abuts against and is fixed to the baffle formed inside the first folding plate.

[0009] Preferably, the telescopic protrusion includes a mounting block inserted into the first folding plate and a card head insertion hole opened on the mounting block, into which a strip-shaped protrusion is inserted.

[0010] Preferably, the mounting clip is inserted into the first folding plate and fixed to the first folding plate by screws.

[0011] Preferably, the shape of the strip-shaped protrusion matches the shape of the spring socket and is inserted into the spring socket to form a resistance with the compression spring.

[0012] Preferably, one side of the strip-shaped protrusion is provided with a control handle that controls the extension and retraction of the strip-shaped protrusion on the card head insertion hole, and one side of the mounting block is provided with a lateral slide rail that matches the moving direction of the control handle.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating a spring-loaded telescopic structure and a limiting latch, fingers or other objects can be effectively prevented from being caught during skateboard folding, significantly reducing the risk of injury caused by improper operation. The combination of the spring-loaded ejection structure and the telescopic latch with the limiting latch ensures the stability of the skateboard during folding, preventing the skateboard from accidentally popping open or failing to lock properly, thus increasing the safety and reliability of operation.

[0015] This design avoids excessive reliance on precise user operation. The automated anti-pinch mechanism makes the folding process smoother, reduces complex manual operation steps, and improves ease of use. The reasonable spring telescopic structure design helps to disperse the impact force during the folding process, reduces wear on structural components, and thus extends the life of the skateboard. Through innovative anti-pinch design, it can stand out in the market, attract consumers who value safety and convenience, and enhance the product's competitiveness. Attached Figure Description

[0024] See Figure 1-5As shown, a folding anti-pinch structure for a skateboard includes a first folding plate 1, a second folding plate 2 connected to the first folding plate 1 via a hinge, a spring telescopic structure 3 disposed within the first folding plate 1, and a limiting slot 4 disposed at the folding surface of the second folding plate 2. The spring telescopic structure 3 includes a spring ejection structure 31 disposed within the first folding plate 1, and a telescopic protrusion 32 disposed within the first folding plate 1, which is ejected outward via the spring ejection structure 31 and cooperates with the limiting slot 4.

[0025] Through a meticulously designed spring telescopic mechanism and precise limiting latch 4, we have successfully avoided the risk of fingers or other objects being pinched during folding, greatly improving user safety when using the skateboard. The spring-protruding structure 31 automatically pushes the telescopic latch 32 to engage tightly with the limiting latch 4, effectively preventing the skateboard from accidentally pinching the user's fingers or clothing during folding, ensuring user safety. This structural design allows for precise alignment and locking during folding, avoiding the instability or misalignment that may occur in traditional folding designs, thus improving the stability and reliability of the skateboard.

[0026] Meanwhile, the design of the spring-telescopic structure 3 makes folding the skateboard simpler and easier. Users don't need to perform complicated manual operations; they can easily fold the skateboard simply by operating the spring-telescopic structure 3. This design not only improves the user experience but also reduces the difficulty of use.

[0027] Furthermore, through the rationally designed spring telescopic structure 3, we can effectively disperse the stress generated during folding, reducing wear on the folding connection components, thereby improving the skateboard's durability and extending its service life. This structural design helps slow down the aging and damage of the folding hinge 5 components, ensuring the skateboard's long-term stable operation and providing users with a more reliable and durable product.

[0028] A folding hinge 5 is provided on one side of the first folding plate 1 and the second folding plate 2. One end of the folding hinge 5 is fixed to the first folding plate 1 with screws, and the other end is fixed to the second folding plate 2 with screws.

[0029] The use of screws and bolts for fastening ensures a more secure connection between the first folding plate 1 and the second folding plate 2, avoiding the loosening or instability that can occur with traditional folding structures, thus improving the safety and stability of the skateboard. The screw and bolt fastening method also simplifies the disassembly and replacement of the folding hinge 5. When the hinge components wear or are damaged, users can easily perform repairs or replacements without replacing the entire folding structure, reducing maintenance costs and operational complexity. The screw and bolt connection method allows users to adjust the tightness of the connection as needed, providing a degree of flexibility. For example, during use, the tightness of the bolts can be adjusted according to the wear condition of the folding hinge 5 to ensure the folding structure is always in optimal working condition, enhancing the skateboard's durability and adaptability.

[0030] The spring ejection structure 31 includes two spring mounting posts 311 inserted into the first folding plate 1, a spring insertion hole 312 opened on the spring mounting post 311, and a compression spring 313 inserted into the spring insertion hole 312; the spring mounting post 311 is inserted into the first folding plate 1 and abuts against and is fixed to the baffle formed inside the first folding plate 1.

[0031] The design of the spring mounting post 311 and the compression spring 313 provides constant elastic support, ensuring that the spring ejection structure 31 can operate stably during the folding and unfolding of the skateboard. With the ejection action of the compression spring 313, the skateboard can achieve precise folding, locking, and unfolding, thereby reducing human error and ensuring the stability and reliability of the skateboard during use.

[0032] The design of the spring mounting post 311 allows the spring to be securely fixed within the first folding plate 1 and to form abutment against the baffle, which enhances the durability of the entire structure. Even during frequent folding operations, the stability of the spring and structure effectively reduces wear and ensures good working performance even after prolonged use.

[0033] This design not only facilitates the installation and replacement of the spring, but also simplifies the assembly process of the entire structure through the cooperation of the spring mounting post 311 and the baffle. Users or manufacturers can easily replace or adjust the compression spring 313, reducing the difficulty of maintenance and repair, while ensuring the stability and reliability of the spring ejection structure 31 in use.

[0034] The telescopic protrusion 32 includes a mounting block 321 inserted into the first folding plate 1, and a head insertion hole 322 opened on the mounting block 321. A strip-shaped protrusion 323 is inserted into the head insertion hole 322. The mounting block 321 is inserted into the first folding plate 1 and is fixed to the first folding plate 1 by screws. The shape of the strip-shaped protrusion 323 matches the shape of the spring insertion hole 312 and is inserted into the spring insertion hole 312 to form a resistance with the compression spring 313.

[0035] The design of the telescopic latch 32, through the matching shape of the strip-shaped protrusion 323 and the spring insertion hole 312, enables precise locking and positioning, ensuring accurate alignment and fixation of the folding structure during operation. This structure avoids misalignment caused by errors, improving the stability and smoothness of the skateboard during folding and unfolding.

[0036] By inserting the strip-shaped protrusion 323 into the spring socket 312 and forming a counterforce with the compression spring 313, an effective pressure dispersion mechanism is created. This enhances the durability and impact resistance of the skateboard's folding section, preventing damage or aging caused by excessive friction or pressure concentration during long-term use.

[0037] The mounting block 321 is secured with screws, simplifying the assembly process and allowing users to easily install, disassemble, and maintain the structure. The design of the strip-shaped protrusion 323 and the clip insertion hole 322 also makes the clip structure easy to replace or adjust, reducing maintenance costs and operational complexity.

[0038] One side of the strip-shaped protrusion 323 is provided with a control handle 324 that can control the extension and retraction of the strip-shaped protrusion 323 on the card insertion hole 322, and one side of the mounting block 321 is provided with a lateral slide rail 325 that matches the moving direction of the control handle 324.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
