A support structure for roller skates

Abstract

This utility model discloses a support structure for roller skates, relating to the field of roller skate technology. The utility model includes a roller frame and further includes: a buffer section disposed on the top of the roller frame; several quick-release sections, all disposed on the roller frame; the buffer section includes a buffer assembly mounted on the top of the roller frame; and a folding assembly mounted on the buffer assembly; the buffer assembly includes two rectangular plates fixedly connected to the top of the roller frame. By incorporating a buffer section, this utility model solves the problem of directly fixing the skate body to the bottom roller support without a buffer space. This results in the user being directly impacted by the ground impact force when encountering bumps, changes in speed, or accidental collisions, as the lack of a buffer structure allows the impact force to be directly transmitted to the skate body, thus affecting the foot and leg joints.

Description

Technical Field

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

[0002] The support structure for roller skates refers to the core component system integrated into the roller skate body to enhance the stability of the shoe, distribute foot pressure, and ensure skating safety and control. It is usually in the form of a shell, frame, support plate, and connecting parts, covering key areas from the toe to the heel. For example, the ankle and foot are fixed by a rigid or semi-rigid shell made of PP or PC material, the reinforced frame on the sides or middle of the shoe body is used to improve the resistance to deformation, and the detachable support plate is used to adapt to different foot shapes and skating scenarios such as freestyle, speed skating, and braking. At the same time, through the coordinated design with the sole and straps, it can limit excessive foot sway while also ensuring a certain degree of flexibility.

[0003] However, existing devices directly fix the shoe body to the bottom roller bracket during use, without any buffer space between the two. This means that when the user encounters bumpy roads, changes in speed, or accidental collisions while gliding, the impact force from the ground is directly transmitted to the shoe body due to the lack of a buffer structure to dissipate the force, and then acts on the foot and leg joints. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure for roller skates. By setting a buffer part, it solves the problem that when the shoe body is directly fixed to the bottom roller bracket, there is no buffer space between the two. This causes the impact force of the ground to be directly transmitted to the shoe body when the user encounters bumpy road, turns, speed changes, or accidental bumps while skating, due to the lack of a buffer structure to absorb the force. This impact force then acts on the foot and leg joints.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a support structure for roller skates, including a roller frame and further comprising: a buffer section disposed on the top of the roller frame; several quick-release sections disposed on the roller frame; the buffer section includes a buffer assembly mounted on the top of the roller frame; and a folding assembly mounted on the buffer assembly. The buffer assembly includes two rectangular plates fixedly connected to the top of the roller frame. Two sliding rods are fixedly connected to the sides of the two rectangular plates that are close to each other. Sliding frames are slidably connected to the outer walls of the two sliding rods. Dampers are fixedly connected to the sides of the two rectangular plates that are close to each other. The ends of the two dampers that are close to each other are fixedly connected to the two sliding frames. Each damper has a reset component located in the middle of the two rectangular plates. Each reset component includes springs wound around the two dampers. One end of each spring is fixedly connected to the two rectangular plates, and the other end of each spring is fixedly connected to the two sliding frames. The two springs are located at the ends of the two sliding frames that are far apart from each other.

[0006] Furthermore, the quick-release part includes a limiting component disposed on the pulley frame; and a fixing component mounted on the limiting component.

[0007] Furthermore, the folding assembly includes connecting plates hinged to two sliding frames. A fixed frame is hinged to the end of each connecting plate away from the sliding frame. A fixed plate is fixedly connected to the top of each fixed frame. The connecting plates hinged to the two sliding frames are hinged to the fixed frames. Folding or unfolding of the sliding frames and fixed frames can be achieved by rotating the connecting plates. The fixed plate at the top of the fixed frame can support related components. The hinged structure makes the folding operation flexible and effortless, allowing the device to be reduced in size when not in use, saving storage space, and enabling rapid unfolding and structural stability during use, thus improving the portability and space utilization of the device.

[0008] Furthermore, the limiting component includes a limiting groove on the left side of the pulley frame, a limiting block slidably connected within the limiting groove, two slots on the limiting block, a pulley inside the pulley frame, a locking rod slot on the pulley, both slots communicating with the pulley frame and the sliding rod, a screw on the pulley, both ends of the screw extending beyond the pulley frame and the limiting block, a limiting element on the screw, and the screw being both slidably and rotatably connected to the pulley, pulley frame, and limiting block, the limiting element including a fixed connection. A locking rod is attached to the outer wall of the screw, and the locking rod is adapted to two locking slots. The locking rod is slidably connected to the locking rod slots and slides within the limiting slot through a limiting block. Combined with the sliding and rotational connection between the screw, pulley, pulley frame, and limiting block, the limiting position can be flexibly adjusted. The locking rod on the screw is adapted to the locking slots and can lock the limiting block and pulley at a specific position. The locking rod slots ensure smooth movement of the locking rod. The overall structure can accurately limit the relative movement of the pulley and the sliding rod, and facilitate the adjustment of the limiting state according to needs, thereby improving the stability and adjustment flexibility of the pulley assembly.

[0009] Furthermore, the fixing component includes a limiting groove two opened at the right end of the screw, a limiting ring slidably connected in the limiting groove two, a plurality of pin holes opened on the right side of the pulley frame, a fixing nut threadedly connected to the outer wall of the screw, and four pins provided on the limiting ring, with each of the four pins matching the four pin holes. The limiting ring sliding in the limiting groove two at the right end of the screw, its four pins can be matched and engaged with the pin holes on the right side of the pulley frame. With the fixing nut threadedly connected to the outer wall of the screw, the screw position can be further locked after the limiting ring is engaged and fixed, preventing the screw from rotating or moving accidentally. The overall structure achieves precise positioning through the cooperation of the pins and pin holes, and strengthens the fixing effect with the fixing nut, ensuring the stability of the limiting component's limiting state of the pulley, and improving the reliability of the cooperation between the pulley frame and the sliding rod.

[0010] This utility model has the following beneficial effects: 1. By setting up a buffer section, when the user encounters road bumps, turns, speed changes, or accidental collisions while gliding, the impact force from the ground is transmitted to the roller frame through multiple rollers. At this time, the roller frame cooperates with the shoe body, so that the roller frame between the two is connected by a hinged connecting plate and a fixed frame. The two connecting plates fold outward and compress, causing the two roller frames to slide away from each other on the outer wall of the roller rod. At the same time, the damper and spring on the rectangular plate are compressed to release the impact force. This setting can effectively buffer the impact of the ground, reduce the force on the foot and leg joints, and improve gliding comfort and safety. 2. By setting up a quick-release mechanism, if it is necessary to disassemble the pulley and pulley frame during use, first use the tool to remove the fixing nut on the screw, and then slide out the limiting ring stuck on the screw; then rotate the screw 90 degrees, so that it drives the locking rod at the other end to rotate into the locking rod groove to release the limit. Then, through the locking rod groove, let the screw drive the locking rod to move out of the limiting block, pulley frame and pulley, so that the pulley can be easily replaced. When installing, follow the reverse steps. This setting can realize quick disassembly and assembly of pulleys, which facilitates the maintenance and replacement of parts.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, this utility model is a support structure for roller skates, including: a pulley frame 1, and further including: a buffer part 2, the buffer part 2 is disposed on the top of the pulley frame 1; quick release parts 3, a plurality of quick release parts 3 are disposed on the pulley frame 1.

[0017] The buffer section 2 includes a buffer assembly 21, which is mounted on the top of the pulley frame 1; and a folding assembly 22, which is mounted on the buffer assembly 21. The buffer assembly 21 includes two rectangular plates 211 fixedly connected to the top of the pulley frame 1.

The two springs 215 are located at the ends of the two sliding frames 213 that are far apart from each other. By setting the buffer part 2, when the user encounters road bumps, turns, or accidental collisions while gliding, the impact force of the ground will be transmitted to the pulley frame 1 through multiple pulleys 314. At this time, the pulley frame 1 cooperates with the shoe body, so that the sliding frame 213 between them is folded and compressed outward by the two connecting plates 221 and the fixed frame 222, causing the two sliding frames 213 that are hinged to them to slide away from each other on the outer wall of the two sliding rods 212.

The locking rod 317 is adapted to two locking slots 313, and the locking rod 317 is slidably connected to the locking rod slot 315. By providing a quick-release part 3, if it is necessary to disassemble the pulley 314 and the pulley frame 1 during use, the fixing nut 324 fixed to the screw 316 can be removed first using a tool, and then the locking nut 324 can be slid outward to remove the locking part. The limiting ring 322 on the screw 316 is then rotated 90 degrees, causing the locking rod 317 at the other end to rotate to the locking rod groove 315, releasing the limiting on the other end of the screw 316. Then, the screw 316 can drive the locking rod 317 out of the limiting block 312, the pulley frame 1 and the pulley 314 through the locking rod groove 315, which facilitates the replacement of the pulley 314 and other operations. The installation can be carried out by referring to the reverse steps. With this setting, the pulley can be quickly disassembled and assembled, which is convenient for maintenance and replacement of parts.

[0019] A specific application of this embodiment is as follows: During use, when the user encounters road bumps, steering changes, or accidental collisions while gliding, the impact force is transmitted to the pulley frame 1 via multiple pulleys 314. At this time, the pulley frame 1 cooperates with the shoe body, so that the sliding frame 213 between them, with the help of the hinged connecting plate 221 and the fixed frame 222, is compressed outward by the two connecting plates 221, causing the two sliding frames 213 hinged to them to slide away from each other on the outer walls of the two sliding rods 212. At the same time, the dampers 214 and springs 215 on the two rectangular plates 211 are compressed, thereby releasing the impact force. Through this setting, the impact of the ground can be effectively buffered, the force on the foot and leg joints can be reduced, and the gliding comfort can be improved. For both appropriateness and safety, if it is necessary to disassemble pulley 314 and pulley frame 1 during use, first use a tool to remove the fixing nut 324 fixed on screw 316, then slide outward to remove the limiting ring 322 stuck on screw 316, then rotate screw 316 ninety degrees so that it drives the locking rod 317 at the other end to the locking rod groove 315, releasing the limiting on the other end of screw 316. Then, screw 316 can drive locking rod 317 through locking rod groove 315 to move out of limiting block 312, pulley frame 1 and pulley 314, which is convenient for replacing pulley 314 and other operations. The installation can be carried out by referring to the reverse steps. With this setting, the pulley can be quickly disassembled and assembled, which is convenient for maintenance and replacement of parts.
