[0002] With the development of society and the improvement of people's living standards, people's entertainment methods are gradually enriched. Roller skates are a type of footwear with rollers on the sole for sliding on flat roads. Wearing roller skates can achieve a higher moving speed by continuously exerting force on the legs under the action of one's own gravity and inertia. However, when roller skates encounter bumps or need to brake at a higher moving speed, they can only decelerate by friction between the heel of the sole and the ground. The deceleration and braking function is single, and when braking, the foot needs to be lifted up with the ankle as the center, so that the heel rubs against the ground, and at this time only the rear wheel is in contact with the ground, and the contact area is extremely small, which can easily lead to imbalance and falls due to bumps.

[0012] Beneficial effects of the present invention:

[0013] The high-stability roller skates of the present invention are provided with a stable control function. Both sides of the roller skate base are equipped with a balancing leg structure. When an emergency brake operation is required during high-speed sliding, the heel deceleration part is decelerated by friction with the ground by conventional ankle force. At this time, only the last pulley is in contact with the ground, and the contact area is small and the wheel slippage is high, which makes it easy to lose balance and fall. By setting up the balancing leg structure, when an emergency brake action is performed, the torsion structure drives the balancing legs on both sides to rotate to an inclined position close to the ground, and cooperates with the leg elastic extension structure to make the friction deceleration blocks at the bottom of the leg structure contact with the ground to assist in the deceleration effect. At the same time, the friction deceleration blocks on both sides cooperate with the heel deceleration part to form an inverted triangle support structure, and the rear wheel is placed inside the inverted triangle, so that the sliding and deflection of the rear wheel are controlled through the friction support deceleration at three points, thereby greatly improving the stability during the brake action and achieving the deceleration effect during the emergency brake.

[0014] The high-stability roller skates of the present invention are provided with a stable control function. The deceleration heel of the heel deceleration structure on the rear side of the base is elastically extendable. When the brake stop operation is performed, the deceleration heel is driven by the extension structure to be placed in front of the contact point in advance, so that the deceleration heel can contact the ground without the ankle being bent vigorously, and the balanced leg structure is cooperated to achieve stable deceleration. At the same time, the deceleration heel is partially slid back with the force of the ankle, and pressure is input into the rear wheel deceleration structure through the pneumatic transmission component, so that the friction force of the rear wheel axle is increased to achieve active speed control effect, thereby achieving labor-saving and stable deceleration and speed control effect;

[0015] The high stability roller skates of the present invention are provided with a smooth control function. The balancing leg structures on both sides of the base can not only realize auxiliary deceleration to form a three-point support smooth deceleration effect, but also, when used by beginners or in the stage where the safety factor needs to be improved, the front side of the balancing leg board is provided with an auxiliary pulley, and the angle of the balancing leg board is driven by the torsion structure to be in contact with the ground, so that the auxiliary pulleys form an auxiliary balancing effect on the front two sides of the base, so that the movement balance is improved and the elastic structure is used to avoid affecting the sliding experience when sliding force is applied. When the balancing leg structures are placed on both sides to assist in sliding, when imbalance occurs or emergency braking is required, the speed of balancing braking through the torsion structure is further increased because of their current position close to the ground, thereby further ensuring the smooth control effect when the roller skates move forward.

For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front, and back directions mentioned below are the same as Figure 1 The up-down, left-right, front-back directions of the projection relationship itself are consistent.

[0024] A high-stability roller skate described in conjunction with Figures 1-5 includes a shoe body 11, the shoe body 11 is equipped with a mounting bottom shell 12, the mounting bottom shell 12 is equipped with a roller skating base 14, the roller skating base 14 is rotatably equipped with pulleys 15, the rearmost pulley 15 is fixedly equipped with a rear wheel speed control device 25, the rear wheel speed control device 25 includes a speed control function block 31, the speed control function block 31 is provided with a speed control cavity 32, the speed control cavity 32 is rotatably equipped with a shaft connecting block 36, the shaft connecting block 36 is fixedly connected to the wheel axle of the rear wheel speed control device 25, the inner wall of the speed control cavity 32 is equipped with a speed control friction bag 33 that can be pressurized and expanded, and the roller skating base 14 is equipped with a heel deceleration device 2 0, the heel deceleration device 20 includes a heel carrier 21, the heel carrier 21 can be lifted and slidably installed with a deceleration heel 29, the roller skating base 14 is symmetrically slidably installed with a torsion device 40, the torsion device 40 includes a torsion carrying block 51, the torsion carrying block 51 is rotatably installed with a rotating slide 43, the rotating slide 43 is slidably installed with an elastic sliding rod 44, the elastic sliding rod 44 is installed with an elastic spring 45, the end of the elastic sliding rod 44 is rotatably installed with a leg plate 46, the leg plate 46 is installed with an auxiliary pulley plate 47, the end of the leg plate 46 is installed with a friction deceleration block 50, and the roller skating base 14 is symmetrically installed with a limited fixed plate 49.

[0025] When working, by wearing the shoe body 11, the pulley 15 is rotated to slide under the force of the foot. Under normal circumstances, the deceleration and braking are achieved by applying force on the wrist or by the deceleration heel 29 being stretched downward to contact the ground to achieve the deceleration and braking effect. When the sliding speed is high or an emergency braking effect is required under special circumstances, the foot slightly applies force to make the roller skating base 14 rotate counterclockwise, and the transmission structure in the heel deceleration device 20 drives the deceleration heel 29 to move downward. During the process, the torsion device 40 drives the rotating slide 43 to rotate clockwise. The leg plate 46 and the elastic sliding rod 44 are connected to the rotating shaft and a torsion spring is installed. Its initial state is the tilt angle shown in the figure. Therefore, when the rotating slide 43 is driven to tilt, the elastic sliding rod 44 retracts, so that the leg plate 46 is no longer restricted by the limit fixing plate 49, and the elastic sliding rod 44 pops out, driving the friction deceleration block 50 to generate friction with the ground to assist in deceleration. The deceleration heel 29 is pressed against the ground with the force of the ankle, and the deceleration heel 29 and the friction deceleration blocks 50 on both sides form an inverted triangle. The invention relates to a stable structure, and the rear wheel is placed in the triangular structure, thereby improving the deceleration efficiency and further improving the stable balance effect. At the same time, the ankle exerts force, so that the deceleration heel 29 is further squeezed with the ground, so that the deceleration heel 29 gradually retracts to the normal braking position, and the back pressure effect causes the air pressure transmission in the heel deceleration device 20 to pressurize the speed control friction bag 33, so that the speed control friction bag 33 collides and squeezes the shaft rotating block 36, thereby controlling the speed of the rear wheel so that a stable deceleration is achieved in cooperation with the inverted triangle deceleration effect, and the problem of unbalanced rear wheel slip after braking is prevented. The leg plate 46 can be controlled by the torsion device 40 to perform an auxiliary sliding balance effect during the sliding process. The torsion device 40 drives the leg plate 46 to rotate counterclockwise, so that the wheel part of the auxiliary pulley plate 47 contacts the ground first, thereby performing auxiliary sliding without braking effect, and supporting on both sides to improve the sliding balance degree. At this time, the leg plate 46 is in place, and when emergency braking is required, a stable support deceleration effect can be achieved more quickly.

[0031] The air pressure transmitted through the air pressure output port 26 pushes the push piston 38 to slide, so that the push piston 38 squeezes the liquid in the hydraulic transfer groove 34 and inputs it into the speed control friction bag 33, so that the speed control friction bag 33 expands and forms friction extrusion with the shaft connecting block 36, thereby achieving braking of the rear wheels.
