Description

Technical Field

[0001] This utility model belongs to the field of pulley installation technology, and in particular relates to a pulley installation structure for roller skates. Background Technology

[0002] Roller skates are a type of sports equipment that uses wheels mounted on the sole for gliding on the ground. They are commonly used for recreational activities, sports training, or professional competitions. The wheels are not directly fixed to the skate frame but require a specific mounting structure. The core reason for this is that the structure can achieve multiple key functions: it can stably connect the wheels to the skate frame, preventing the wheels from loosening and falling off during skating, thus ensuring safety; it can also adjust the angle and spacing of the wheels to adapt to the flexibility or stability requirements of different skating scenarios; in addition, the mounting structure can also cushion vibrations and impacts during skating, reducing the force on the feet, improving skating comfort, and making it easier for users to control the direction and speed of skating, ensuring that roller skating is safe and smooth.

[0003] However, in the existing roller installation structure, the rollers may become loose or shift during use due to the vibration generated by the roller skates, increasing safety risks and affecting the structural stability of the roller skates. Utility Model Content

[0004] The purpose of this utility model is to provide a pulley mounting structure for roller skates. By setting a fastening part, it solves the problem that in the existing pulley mounting structure, the rollers may become loose or shift during use due to the vibration generated by the roller skates, which increases safety risks and affects the structural stability of the roller skates.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a roller skate installation structure, comprising a roller skate and a support frame fixedly connected to the bottom of the roller skate. The support frame has a plurality of rollers. The structure further includes: a plurality of fastening parts mounted on the support frame; a plurality of limiting parts mounted on the fastening parts; each fastening part including a fastening assembly mounted on the support frame; and a driving assembly mounted on the fastening assembly. The fastening assembly includes a hollow rod mounted on the roller skate, the hollow rod having a cylindrical groove. The internal fixed connection includes several fixed blocks, each of which is slidably connected to a sliding rod. The right side of each sliding rod extends beyond the hollow rod, and both sliding rods are slidably connected to the hollow rod. Fasteners are provided on each sliding rod. Four pulleys are provided, with four fastening and four limiting parts arranged in a linear array. Four fixed blocks are provided, arranged in a circumferential array within the cylindrical groove. The fasteners include a fastening plate rotatably connected to the outer wall of the cylindrical rod, which is fixedly connected to the sliding rods. The fastening plate is located on the right side of the hollow rod and clamps the pulleys through cooperation with the arc-shaped block, enhancing the fixing effect and preventing the pulleys from loosening during sliding.

[0006] Furthermore, the limiting part includes a support assembly mounted on the hollow rod; a limiting assembly mounted on the support assembly; and the support assembly located inside the hollow rod.

[0007] Furthermore, the drive assembly includes a cylindrical rod disposed within a hollow rod. A threaded groove is formed on the inner wall of the hollow rod, and a threaded protrusion is fixedly connected to the outer wall of the cylindrical rod. The threaded groove and the threaded protrusion are configured to interact. An auxiliary component is provided on the outer wall of the cylindrical rod. The cylindrical rod is threadedly connected to the hollow rod through the engagement of the threaded groove and the threaded protrusion. The auxiliary component includes a drive handle fixedly connected to the outer wall of the cylindrical rod. The drive handle is located on the right side of the fastening plate, and can be tightened or loosened simply by rotation, improving operational convenience and serving as the core power source for the fastening component.

[0008] Furthermore, the support assembly includes several rectangular slots formed on the hollow rod, a rectangular block is fixedly connected to the inner left wall of the hollow rod, and several telescopic rods are fixedly connected to the outer wall of the rectangular block; four rectangular slots and four telescopic rods are provided, arranged in a circumferential array, and the rectangular slots are formed on the hollow rod to provide space for the extension and retraction of the arc-shaped block.

[0009] Furthermore, the limiting assembly includes arc-shaped blocks fixedly connected to the opposite sides of several telescopic rods. Springs are sleeved on the outer walls of several telescopic rods. The opposite sides of several springs are fixedly connected to several arc-shaped blocks, and the opposite sides of several springs are fixedly connected to rectangular blocks. Several arc-shaped blocks are located at several rectangular slots, and several springs are located inside hollow rods to ensure that the arc-shaped blocks are tightly engaged.

[0010] This utility model has the following beneficial effects: 1. By setting a fastening part, the cylindrical rod is rotated by the drive, and the cylindrical rod rotates on the fastening plate. With the help of the threaded groove and threaded protrusion, it moves into the hollow rod, and at the same time drives the fastening plate to move. With the assistance of several sliding rods, the fastening plate moves smoothly and moves closer to the support frame. Finally, through the cooperation of the fastening plate and several arc-shaped blocks, the fixing stability of the pulley is further improved, effectively reducing the loosening or displacement of the pulley during use, and greatly improving the structural stability and safety of roller skates during use. 2. By setting a limiting part, the pulley is first placed between the support frames, and then the hollow rod is inserted into the pulley. During the process, the arc-shaped block is squeezed closer and squeezes the telescopic rod and spring, causing it to deform and generate elastic force. After the arc-shaped block passes through the support frame, it returns to its original position under the action of the spring force, thereby fixing the pulley between the support frames. When disassembling, pinch the arc-shaped block to bring it closer together, and the hollow rod can be removed and the pulley can be removed. The installation process uses the compression and elastic force of the structure itself to fix the pulley. The operation is convenient and efficient, without complicated tools, greatly simplifying the pulley disassembly and assembly process.

By pinching the arc-shaped blocks 321, the pulley 113 can be fixed in place. The blocks 321 move closer together, thereby removing the hollow rod 211 and disassembling the pulley 113. The cylindrical rod 221 is rotated by the drive handle 224. At this time, the cylindrical rod 221 rotates on the fastening plate 215. The cylindrical rod 221 moves into the hollow rod 211 under the action of the threaded groove 222 and the threaded protrusion 223. The cylindrical rod 221 drives the fastening plate 215 to move. Under the action of several sliding rods 214, the fastening plate 215 moves smoothly and moves closer to the support frame 112. The fastening plate 215 and several arc-shaped blocks 321 work together to improve the stability of the pulley 113.
