Description

Technical Field

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

[0002] Inline skate deceleration devices are specialized components installed on inline skates such as inline skates and quad skates. They help users actively reduce speed, control skating rhythm, or assist in stopping smoothly during skating. Their core function is to generate resistance through friction between the device and the ground, as well as wheel braking, to counteract the skating inertia of the skates and prevent loss of control due to excessive speed. Common types include rubber brake blocks installed on the heel, which achieve deceleration by lifting the toes and the brake blocks touching the ground.

[0003] In existing devices, the pulley and brake pads are mostly fixed by bolts. When users need to replace the brake pads after long-term use, they must first remove the bolts. This is not only cumbersome and time-consuming, making it difficult to replace quickly, but it also further affects the continuity and safety of gliding. Utility Model Content

[0004] The purpose of this utility model is to provide a deceleration device for roller skates. By setting a fixing part, it solves the problem that the fixing of the pulley and the brake block mostly relies on bolt connection. When the user needs to replace the brake block after long-term use, the bolt must be removed first. This is not only cumbersome and time-consuming, making it difficult to achieve quick replacement, but also further affects the continuity and safety of skating.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a deceleration device for roller skates, comprising a roller skate and further comprising: a fixing part disposed on the back of the roller skate; a buffer part disposed on the fixing part; the fixing part comprising a fixing component mounted on the roller skate; and a configuration component mounted on the fixing component; the fixing component comprising a T-shaped sliding frame fixedly connected to the back of the roller skate, a T-shaped connecting block slidably connected within the T-shaped sliding frame, two fixing grooves formed on the T-shaped sliding frame and the T-shaped connecting block, each fixing groove containing a screw rod slidably connected to a screw rod, the outer walls of each screw rod being threaded with a nut, and a folding groove formed at the end of each screw rod away from the nut, each folding groove containing two folding rods rotatably connected to a folding groove, the four folding rods being respectively adapted to the two folding grooves.

[0007] Furthermore, the buffer section includes a connecting assembly mounted on a T-shaped connecting block; and a buffer assembly mounted on the connecting assembly, the buffer assembly being located at the bottom of the connecting assembly.

[0008] Furthermore, the configuration component includes two springs (I) disposed on one side of several folding rods that are close to each other; two stops (I) fixedly connected in each of the two folding slots; several stops (I) adapted to several folding rods; several stops (II) fixedly connected to the right side of the T-shaped connecting block; several stops (II) adapted to several folding rods; the two springs (I) on the one side of the folding rods that are close to each other can automatically push the folding rods to reset and unfold after the screw has fully penetrated the fixing slot, providing a reliable limit for the screw and ensuring a stable connection between the brake block and the roller skate; the stops (I) in the folding slots are adapted to the folding rods and can limit the unfolding range of the folding rods, preventing them from over-unfolding and affecting the subsequent nut tightening operation.

[0009] Furthermore, the connecting assembly includes a brake block disposed at the bottom of the T-shaped connecting block, a slide rod assembly fixedly connected to the top of the brake block, two slide frames slidably connected to the outer wall of the slide rod assembly, each slide frame being provided with a connector, a reset component being provided on the slide rod assembly, the slide rod assembly consisting of two slide rods, the connectors including connecting rods hinged to the two slide frames, a fixed frame hinged to the end of each connecting rod away from the slide frame, the top ends of each fixed frame being fixedly connected to the T-shaped connecting block, the slide frame, connecting rod, and fixed frame forming a combination, and such a combination has two... The reset component includes two springs wound around the slide rod assembly. The ends of the two springs, which are far apart from each other, are fixedly connected to two sliding frames. The brake block at the bottom of the T-shaped connecting block is connected to the two sliding frames through the slide rod assembly. The sliding frames are hinged to the fixed frame through the connecting rod. The two sets of sliding frames, connecting rods, and fixed frames are symmetrically distributed. With the help of the two springs connected to the sliding frames on the slide rod assembly, when the brake block rubs against the ground, the sliding frames slide along the slide rod assembly and the springs compress and accumulate potential energy to achieve braking buffer. At the same time, the springs can push the sliding frames to reset after braking, causing the brake block to return to its initial position.

[0010] Furthermore, the buffer assembly includes several dampers fixedly connected to the top of the brake block. The top ends of each damper are fixedly connected to a T-shaped connecting block. Each damper is provided with a reset element II. There are four dampers. Each reset element II includes a spring III wrapped around the outer wall of the dampers. One end of each spring III is fixedly connected to the T-shaped connecting block, and the other end of each spring III is fixedly connected to the brake block. There are four spring IIIs, each wrapped around the outer wall of a damper. The four dampers fixed between the top of the brake block and the T-shaped connecting block, together with the four spring IIIs wrapped around their respective outer walls, can form a double buffer structure when the brake block rubs against the ground. The dampers can reduce the impact speed of the brake block through their own damping characteristics, while the spring IIIs further absorb impact energy through compression deformation. The two work together to significantly reduce the vibration during braking.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting a fixing part, when it is necessary to assemble the brake block and roller skate, first slide the T-shaped connecting block into the T-shaped sliding frame, and then insert the screw into the fixing groove of the two. The fixing groove squeezes the two folding rods on the screw to retract into the folding groove. After the screw is fully inserted, the folding rod is pushed by the first spring to reset and unfold and limit the position. Rotate the nut to cooperate with the folding rod to complete the fixation. During this period, the second stop restricts the rotation of the folding rod to prevent the screw from moving randomly, and the first stop restricts the folding rod from over-expanding. This setting can quickly and firmly connect the two and simplify the disassembly and replacement steps.

[0013] 2. By setting up a buffer section, if it is necessary to slow down the roller skates, the operator can lift their toes to tilt the heel of the roller skate, allowing the brake block to rub against the ground to slow down. When the brake block slows down, multiple dampers on its top and spring three play a buffering role. At the same time, the two sets of symmetrically distributed sliding frames, connecting rods and fixed frames on the brake block will slide closer to each other along the sliding rod group and compress spring two, allowing spring two to accumulate potential energy to support the subsequent reset of the brake block. This setting can effectively ensure the stability of the brake block during the buffering process.

[0014] 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

[0023] 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.

[0024] Please see Figure 1-5 As shown, this utility model is a deceleration device for roller skates, including roller skate 1, and further including: a fixing part 2, which is disposed on the back of roller skate 1; and a buffer part 3, which is disposed on the fixing part 2.

[0025] The fixing part 2 includes a fixing component 21, which is mounted on the roller skate 1; and a configuration component 22, which is mounted on the fixing component 21. The fixing component 21 includes a T-shaped slide frame 211 fixedly connected to the back of the roller skate 1. A T-shaped connecting block 212 is slidably connected inside the T-shaped slide frame 211. Two fixing grooves 213 are formed on the T-shaped slide frame 211 and the T-shaped connecting block 212. A screw 214 is slidably connected inside each of the two fixing grooves 213. Nuts 215 are threaded onto the outer walls of the two screws 214. A folding groove 216 is formed at the end of each screw 214 away from the nut 215. Two folding grooves 216 are rotatably connected inside each of the two folding grooves 216. Four folding rods 217 are adapted to two folding slots 216 respectively. The configuration component 22 includes two springs 221 disposed on one side of the plurality of folding rods 217 close to each other. Two stops 222 are fixedly connected in each of the two folding slots 216. The plurality of stops 222 are adapted to the plurality of folding rods 217. A plurality of stops 223 are fixedly connected to the right side of the T-shaped connecting block 212. The plurality of stops 223 are adapted to the plurality of folding rods 217. By setting the fixing part 2, when it is necessary to assemble the brake block 311 with the roller skate 1, the T-shaped connecting block 212 can be slid into the T-shaped sliding frame 211 first. Insert the screw 214 into the fixing groove 213 on the T-shaped slide frame 211 and the T-shaped connecting block 212. During insertion, the fixing groove 213 will compress the two rotatable folding rods 217 on the screw 214. As the screw 214 goes deeper, the two folding rods 217 will be compressed and retracted into the folding groove 216 of the screw 214 to avoid interfering with the screw 214 penetrating the fixing groove 213. When the screw 214 has completely penetrated the fixing groove 213, the two folding rods 217 will be reset and unfolded under the push of the two springs 221, which will limit the penetration end of the screw 214. Then, the operator can use a tool to turn the nut on the screw 214. 215. The screw 214 engages with the two unfolded folding rods 217 to retract and fix them. In addition, when the screw 214 drives the two folding rods 217 to rotate, the two stops 223 on the T-shaped slide frame 211 will limit the folding rods 217 to prevent the screw 214 from rotating unnecessarily and affecting the screwing of the nut 215. During the retraction of the screw 214 and the folding rods 217, the two stops 222 in the folding groove 216 will limit the unfolded folding rods 217 to prevent them from over-unfolding. Through this assembly setting, the brake block 311 and the roller skate 1 can be quickly and securely connected, while simplifying the subsequent disassembly and replacement operation steps.

[0026] The buffer section 3 includes a connecting assembly 31, which is mounted on the T-shaped connecting block 212; and a buffer assembly 32, which is mounted on the connecting assembly 31 and located at the bottom of the connecting assembly 31. The connecting assembly 31 includes a brake block 311 disposed at the bottom of the T-shaped connecting block 212. A slide rod assembly 312 is fixedly connected to the top of the brake block 311. Two sliding frames 313 are slidably connected to the outer wall of the slide rod assembly 312. Each of the two sliding frames 313 is provided with a connector. A reset component is provided on the slide rod assembly 312. The slide rod assembly 312 consists of two slide rods. The buffer assembly 32 includes several dampers fixedly connected to the top of the brake block 311. 321, the top ends of several dampers 321 are fixedly connected to T-shaped connecting blocks 212. Each damper 321 has a reset component. There are four dampers 321. The connecting components include connecting rods 314 hinged to two sliding frames 313. A fixed frame 315 is hinged to the end of each connecting rod 314 away from the sliding frame 313. The top ends of the two fixed frames 315 are fixedly connected to the T-shaped connecting blocks 212. The sliding frame 313, connecting rods 314, and fixed frames 315 form a combination, and there are two such combinations. The reset component includes two springs 316 wound around the sliding rod assembly 312. The two springs 316 are spaced apart from each other. The two ends are fixedly connected to two sliding frames 313. The reset component two includes springs 322 wrapped around the outer wall of several dampers 321. One end of each spring 322 is fixedly connected to a T-shaped connecting block 212, and the other end of each spring 322 is fixedly connected to a brake block 311. There are four springs 322, each wrapped around the outer wall of four dampers 321. By setting the buffer part 3, if it is necessary to decelerate the roller skate 1, the operator only needs to lift the toes, so that the roller skate 1 at the heel forms a certain angle, which will allow the brake block 311 on it to rub against the ground, thereby achieving the purpose of deceleration. At the same time, during the deceleration process of the brake block 311, The multiple dampers 321 and spring 322 on the top of the brake block 311 can buffer the brake block 311. During the buffering process, the two sliding frames 313 on the brake block 311 will cooperate with the connecting rod 314 and the fixed frame 315 that are hinged to it to drive the transmission. There are two sets of the above-mentioned sliding frames, connecting rods and fixed frames, which are symmetrically distributed. When the brake block 311 is buffered, the two sets will slide closer to each other along the sliding rod group 312 and compress the spring 316 on the sliding rod group 312, so that the spring 316 accumulates elastic potential energy to support the subsequent reset of the brake block 311. Through this setting, the stability of the brake block 311 during the buffering process can be effectively guaranteed.

[0027] A specific application of this embodiment is as follows: When the brake block 311 needs to be assembled with the roller skate 1, the T-shaped connecting block 212 can be slid into the T-shaped sliding frame 211 first. Then, the screw 214 is inserted into the fixing groove 213 on the T-shaped sliding frame 211 and the T-shaped connecting block 212. During the insertion process, the fixing groove 213 will compress the two rotatable folding rods 217 on the screw 214. As the screw 214 goes deeper, the two folding rods 217 will be compressed and retracted into the folding groove 216 of the screw 214 to avoid interfering with the screw 214 penetrating the fixing groove 213. When the screw 214 is fully penetrated... After the fixing slot 213 is closed, the two folding rods 217 will be reset and unfolded under the push of the two springs 221, which will limit the end through which the screw 214 passes. Then, the operator can use a tool to rotate the nut 215 on the screw 214, so that the screw 214 and the unfolded two folding rods 217 can retract and fix. In addition, when the screw 214 drives the two folding rods 217 to rotate, the two stops 223 on the T-shaped slide frame 211 will limit the folding rods 217 to prevent the screw 214 from rotating unnecessarily and avoid affecting the screwing of the nut 215. During the retraction process, the two stops 222 within the folding groove 216 limit the unfolded folding rod 217 to prevent over-expansion. This assembly setup allows for a quick and secure connection between the brake block 311 and the roller skate 1, simplifying subsequent disassembly and replacement procedures. To decelerate the roller skate 1, the operator simply lifts their toes, tilting the roller skate 1 at the heel, causing the brake block 311 to rub against the ground, thus achieving deceleration. Simultaneously, during the deceleration process of the brake block 311, multiple dampers 321 and spring 322 on its top can... The brake block 311 acts as a buffer, and during the buffering process, the two sliding frames 313 on the brake block 311 will cooperate with the connecting rod 314 and the fixed frame 315 that are hinged to it for transmission. There are two sets of the above-mentioned sliding frames, connecting rods and fixed frames, which are symmetrically distributed. When the brake block 311 is buffered, the two sets will slide closer to each other along the sliding rod group 312 and compress the second spring 316 on the sliding rod group 312, so that the second spring 316 accumulates elastic potential energy to support the subsequent reset of the brake block 311. Through this setting, the stability of the brake block 311 during the buffering process can be effectively guaranteed.
