Description

Technical Field

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

[0002] The folding structure of roller skate wheels is a special mechanical structure designed to improve the portability and space utilization of roller skates. It is mainly used in recreational or portable roller skates. The core function is to use a specific folding mechanism to allow the originally fixed arrangement of the wheel frame and wheels to be folded and stored when not in use. This can be achieved by bending the frame along a preset axis point, bringing multiple sets of wheels together, or folding the entire wheel frame towards the skate body. This significantly shortens the longitudinal length of the roller skate or reduces its overall volume, making it easier for users to carry in backpacks, tote bags, etc. At the same time, this structure is usually equipped with a reliable locking device that locks the folded parts into a stable straight shape during roller skating, ensuring the rigidity of the wheel frame and skating safety, thus balancing portability and normal skating function.

[0003] However, the existing devices use a non-foldable connection between the pulleys and roller skates, which makes it difficult to compress the device when it is not in use. The overall structure always remains large, which causes a lot of inconvenience for users to move, store, and carry when going out, thus reducing the portability of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a folding structure for roller skate wheels. By setting a folding part, the problem of the non-foldable connection between the roller skate wheels and roller skates is solved. This makes it difficult to compress the size of the device when it is not in use, and the overall structure always maintains a large size, which brings a lot of inconvenience to users in terms of handling, storage and carrying, and thus reduces the portability of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model discloses a folding structure for roller skate wheels, including a roller skate and further comprising: a folding part disposed at the bottom of the roller skate; several limiting parts disposed at the bottom of the roller skate; the folding part including a folding assembly mounted on the bottom of the roller skate; and a resetting assembly mounted on the folding assembly; the folding assembly including a folding groove formed in the bottom of the roller skate, within which two folding rods are rotatably connected, the two folding rods being located away from one end of the roller skate. Each end is rotatably connected to a pulley. A bidirectional screw is fixedly connected inside the folding groove. Two sliding frames are slidably connected to the outer wall of the bidirectional screw. A connecting rod is hinged to each of the two sliding frames. A fixed frame is fixedly connected to the side of each of the two folding rods that is close to each other. The ends of the two connecting rods that are away from the sliding frames are hinged to the two fixed frames. A limiting component is provided on the bidirectional screw. Both of the two folding rods are adapted to the folding groove. The limiting component includes two knobs threaded to the outer wall of the bidirectional screw. The ends of the two knobs that are far from each other are in contact with the two sliding frames.

[0006] Furthermore, the limiting part includes a limiting component installed on the bottom of the roller skate; and a pushing component installed on the limiting component.

[0007] Furthermore, the reset assembly includes two slide rods fixedly connected within the folding groove. A reset component is provided on the outer wall of each slide rod. Each slide rod passes through and is slidably connected to both slide frames. Each reset component includes two springs wound around the outer wall of each slide rod. One end of each spring is fixedly connected to the folding groove, and the other end is fixedly connected to both slide frames. Four springs are provided, wound in pairs around the outer wall of each slide rod. The sliding cooperation between the two slide rods within the folding groove and the slide frames provides stable guidance for the movement of the slide frames. The four springs, wound in pairs around the outer wall of each slide rod, with one end fixed to the folding groove and the other end connected to the slide frames, provide a reset elastic force after the slide frames are moved under force, allowing them to automatically return to their initial position. The configuration of four springs enhances the balance and stability of the reset force, ensuring accurate and reliable reset action.

[0008] Furthermore, the limiting component includes a mounting groove on the bottom of the roller skate, a sliding plate slidably connected in the mounting groove, a limiting plate fixedly connected to the sliding plate, and the limiting plate is adapted to the folding rod. By sliding the mounting groove on the bottom of the roller skate and the sliding plate, the limiting plate is moved. Utilizing the compatibility between the limiting plate and the folding rod, the folding rod can be precisely limited to prevent it from accidentally folding or shifting during roller skating. The sliding connection design makes the limiting operation flexible and convenient, and the limiting state can be quickly switched as needed.

[0009] Furthermore, the pushing component includes a second slide rod fixedly connected in the mounting groove. The outer wall of the second slide rod is provided with a second reset component. The second slide rod passes through the sliding plate and is slidably connected to the sliding plate. The second reset component includes a second spring wound around the outer wall of the second slide rod. One end of the second spring is fixedly connected to the mounting groove, and the other end of the second spring is fixedly connected to the sliding plate. The second slide rod in the mounting groove provides a stable sliding guide for the sliding plate, ensuring that the sliding plate moves accurately without deviation when driving the limiting plate. The second spring wound around the outer wall of the second slide rod connects one end to the mounting groove and the other end to the sliding plate, which can provide a reset elastic force for the sliding plate, so that it automatically returns to its original position after being pushed to continuously adapt to the limiting requirements of the folding rod. It can also enhance the stability of the movement of the sliding plate with the help of the spring force.

[0010] This utility model has the following beneficial effects: 1. By setting up a folding part, when it is necessary to fold and store the roller skates and rollers, first turn the knob on the outer wall of the two-way screw inward to release the limit on the sliding frame. The sliding frame will slide inward under the reset thrust of the spring on the outer wall of the sliding rod. Through the linkage between the connecting rod hinged on the sliding frame and the fixed frame on the folding rod, the folding rod and rollers will be driven to rotate inward and be stored in the folding slot. Another set of this folding mechanism is mirrored. The other roller can be stored by referring to the same steps. This symmetrical folding structure can realize the quick storage of two rollers, reduce the size of the device when not in use, and improve portability. 2. By setting a limiting part, before storing the pulley, the sliding plate needs to be slid outward to move the limiting plate outward to avoid interfering with the storage of the folding rod and pulley into the folding groove. When moving outward, the sliding plate will squeeze the spring on the outer wall of the sliding rod to compress and store force. After the two pulleys are completely stored in the folding groove, the sliding plate is released. The sliding plate will automatically rebound under the reset thrust of the spring, forming a limiting fixation on the folding rod in the folding groove, preventing the folding rod from accidentally moving the pulley out, and ensuring the stability of the storage state.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0015] 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 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 1-5 As shown, this utility model is a folding structure for roller skate wheels, including: a roller skate 1, and further including: a folding part 2, the folding part 2 being disposed at the bottom of the roller skate 1; and a limiting part 3, wherein a plurality of limiting parts 3 are provided, and the plurality of limiting parts 3 are all disposed at the bottom of the roller skate 1.

[0017] The folding part 2 includes a folding assembly 21, which is installed on the bottom of the roller skate 1; and a reset assembly 22, which is installed on the folding assembly 21. The folding assembly 21 includes a folding groove 211 formed in the bottom of the roller skate 1. Two folding rods 212 are rotatably connected in the folding groove 211. The ends of the two folding rods 212 away from the roller skate 1 are each rotatably connected to a pulley 213. A bidirectional screw 214 is fixedly connected in the folding groove 211. Two sliding frames 216 are slidably connected to the outer wall of the bidirectional screw 214. A connecting rod 217 is hinged to each of the two sliding frames 216. A fixing frame 218 is fixedly connected to the side of the two folding rods 212 that is close to each other. The ends of connecting rods 217 away from sliding frames 216 are hinged to two fixed frames 218. Limiting elements are provided on the bidirectional screw 214. The two folding rods 212 are adapted to the folding grooves 211. The reset assembly 22 includes two sliding rods 221 fixedly connected within the folding grooves 211. Reset elements are provided on the outer walls of the two sliding rods 221. Each sliding rod 221 passes through and is slidably connected to the two sliding frames 216. The limiting elements include two knobs 215 threaded to the outer wall of the bidirectional screw 214. The ends of the two knobs 215 away from each other are in contact with the two sliding frames 216. The reset elements include two springs wound around the outer walls of the two sliding rods 221. One end of each of several springs 222 is fixedly connected to the folding groove 211, and the other end of each spring 222 is fixedly connected to two sliding frames 216. Four springs 222 are provided, and each pair is wrapped around the outer wall of the two sliding rods 221. By providing the folding part 2, when it is necessary to fold and store the roller skates 1 and the wheels 213, the knob 215 on the outer wall of the bidirectional screw 214 can be turned inward to release the restriction on the outer sliding frame 216. At this time, the sliding frame 216 will slide inward under the restoring thrust of the springs 222 on the outer wall of the two sliding rods 221. Since a connecting rod 217 is hinged to the sliding frame 216, and the connecting rod 217... The other end is hinged to the fixed frame 218, which is rotatably connected to the folding rod 212 in the folding slot 211. Therefore, during the process of the spring 222 pushing the sliding frame 216 to move inward, the folding rod 212 on the fixed frame 218 can be pulled in conjunction with the connecting rod 217 and the fixed frame 218 to drive the pulley 213 on it to rotate inward, and finally fold and store it in the folding slot 211. At the same time, the folding mechanism also has another set arranged in a mirror image. The other pulley 213 can be folded and stored by referring to the above storage steps. Through this symmetrical folding structure, the two pulleys can be quickly stored, effectively reducing the overall volume of the device in the non-use state and improving portability.

[0018] The limiting part 3 includes a limiting component 31, which is installed on the bottom of the roller skate 1; and a pushing component 32, which is installed on the limiting component 31. The limiting component 31 includes a mounting groove 311 formed on the bottom of the roller skate 1, a sliding plate 312 slidably connected in the mounting groove 311, and a limiting plate 313 fixedly connected to the sliding plate 312. The limiting plate 313 is adapted to the folding rod 212. The pushing component 32 includes a sliding rod 321 fixedly connected in the mounting groove 311. A reset member 2 is provided on the outer wall of the sliding rod 321. The sliding rod 321 passes through the sliding plate 312 and is slidably connected to the sliding plate 312. The reset member 2 includes a spring 322 wound around the outer wall of the sliding rod 321. One end of the spring 322 is fixedly connected to the mounting groove 311, and the other end of the spring 322 is fixedly connected to the sliding plate 312. By setting the limiting part 3, the roller skate 21 is retracted. Before folding, slide the sliding plate 312 outwards to move the limiting plate 313 outwards synchronously. This prevents the limiting plate 313 from interfering with the folding rod 212 and its pulleys 213 being stored in the folding groove 211. During the outward movement of the sliding plate 312, it also compresses the spring 322 on the outer wall of the sliding rod 321, causing the spring 322 to compress and accumulate elastic potential energy, providing power support for the subsequent reset action of the sliding plate 312. Once both pulleys 213 are fully stored in the folding groove 211, the sliding plate 312 can be released. At this time, the sliding plate 312 will automatically rebound under the reset thrust of the spring 322, forming a limiting fixation on the folding rod 212 corresponding to the pulleys 213 stored in the folding groove 211. This prevents the folding rod 212 from accidentally moving the pulleys 213 out of the folding groove 211 under external force, ensuring a stable storage state.

[0019] A specific application of this embodiment is as follows: When using the roller skates 1 and the rollers 213, if it is necessary to fold and store them, the knob 215 on the outer wall of the bidirectional screw 214 can be turned inward to release the restriction on the outer wall slide frame 216. At this time, the slide frame 216 will slide inward under the return thrust of the springs 222 on the outer wall of the two slide rods 221. Since the slide frame 216 is hinged with a connecting rod 217, and the other end of the connecting rod 217 is rotatably connected to the folding rod 212 in the folding groove 211, the slide frame 216 will slide inward. Since the fixed frame 218 is hinged, during the process of the spring 222 pushing the sliding frame 216 inward, the connecting rod 217 and the fixed frame 218 can be linked to pull the folding rod 212 on the fixed frame 218, causing the pulley 213 on it to rotate inward, and finally fold and store it in the folding slot 211. At the same time, the folding mechanism also has another set arranged in a mirror image. The other pulley 213 can be folded and stored in the same way as described above. Through this symmetrical folding structure, two pulleys can be folded and stored. The quick folding effectively reduces the overall size of the device when not in use, improving portability. Simultaneously, before folding the pulley 213, the sliding plate 312 must be slid outwards, causing the limiting plate 313 to move outwards synchronously. This prevents the limiting plate 313 from interfering with the folding rod 212 and its pulley 213 being folded into the folding slot 211. During the outward movement of the sliding plate 312, it also compresses the spring 322 on the outer wall of the sliding rod 321, causing the spring 322... 2. The elastic potential energy is compressed and stored to provide power support for the subsequent reset action of the sliding plate 312. When both pulleys 213 are fully retracted into the folding groove 211, the sliding plate 312 can be released. At this time, the sliding plate 312 will automatically rebound under the reset thrust of the second spring 322, forming a limit fixation on the folding rod 212 corresponding to the pulley 213 retracted in the folding groove 211, preventing the folding rod 212 from accidentally moving the pulley 213 out of the folding groove 211 under the action of external force, and ensuring the stability of the retracted state.
