[0020] See also Figure 1-3 As shown, the utility model provides a technical solution:

[0021] A roller skate with easily replaceable roller skate wheels comprises a base 1 and a wheel frame 2. A T-shaped connecting slot 11 is provided on one side of the base 1. The top of the base 1 is fixedly connected to the bottom of the shoe body of the roller skate. Four T-shaped connecting slots 11 on the base 1 are arranged side by side at equal intervals along the front and rear directions. A pulley 3 is rotatably connected to the wheel frame 2 through a wheel axle. A T-shaped connecting slide 9 is fixedly connected to the top of the wheel frame 2. The T-shaped connecting slide 9 is cooperated with the T-shaped connecting slot 11. A limited slot 91 is provided on the top of the T-shaped connecting slide 9. A limited plug 8 is movably provided inside the base 1. A guide slot 12 is provided inside the base 1. The guide slot 12 is connected to the T-shaped connecting slot 11. The limit plug 8 slides along the guide slot 12. A brake block 7 is fixedly connected to the rear side of the base 1. During the skating process, the friction between the brake block 7 and the ground can achieve braking deceleration.

[0022] The base 1 above the limit plug 8 is rotatably connected to a screw 6 through a bearing. The lower end of the screw 6 is threaded into the limit plug 8. The lower end of the limit plug 8 is inserted into the limit slot 91. The upper end of the screw 6 is sleeved and fixed with a worm gear 5. The worm gear 5 is rotatably connected to the base 1 on the side away from the T-shaped connecting groove 11 through a bearing. The worm 4 is transmission-connected to the worm gear 5. The worm 4 is transmission-connected to the worm gear 5, and the worm 4 is transmission-connected to the worm gear 5 sleeved and fixed on the four screws 6 inside the base 1. The four worm gears 5 are rotated together with the four screws 6 by rotating the worm 4. , can drive the four limiting plugs 8 to move upward along the guide slide 12, so that the lower end of the limiting plug 8 is removed from the limiting slot 91, and then the T-shaped connecting slide 9 can be released from the limit, so that the four wheel frames 2 can be slid out of the T-shaped connecting slide 11 together, and the four pulleys 3 can be replaced synchronously without having to disassemble the individual pulleys 3 one by one, which is more convenient. The rear end of the worm 4 extends to the outside of the base 1 and is fixed with an adjusting handle 41. After a period of use, when the four pulleys 3 need to be replaced uniformly, When the worm 4 is rotated, the adjusting handle 41 can be manually rotated counterclockwise to drive the worm 4 to rotate. The rotation of the worm 4 can drive the four worm wheels 5 to rotate together with the four screws 6. The rotation of the screws 6 can drive the limit plug 8 to move upward along the guide slot 12, so that the lower end of the limit plug 8 is removed from the limit slot 91. At this time, after the T-shaped connecting slide 9 loses the limit of the limit plug 8, the base 1 can be tilted toward the side of the opening of the T-shaped connecting slot 11, so that the four T-shaped connecting slides 9 can slide out of the T-shaped connecting slots 11 where they are located. The wheel 3 is removed from the bottom of the base 1, and then the T-shaped connecting slide 9 above the new pulley 3 is slid into the four T-shaped connecting slots 11 one by one, and the T-shaped connecting slide 9 is slid into the innermost end of the T-shaped connecting slot 11. Then the adjusting handle 41 is manually rotated clockwise to drive the worm 4 to rotate, which can synchronously drive the four limit plugs 8 to move downward along the guide slot 12, so that the lower end of the limit plug 8 is inserted into the limit slot 91, and the T-shaped connecting slide 9 is limited and fixed in the T-shaped connecting slot 11, and the pulley 3 can be replaced.

[0023] Working principle: When in use, after a period of use, when the four pulleys 3 need to be replaced uniformly, the worm 4 can be driven to rotate by manually rotating the adjusting handle 41 counterclockwise. The rotation of the worm 4 can drive the four worm wheels 5 together with the four screws 6 to rotate together. The rotation of the screw 6 can drive the limit plug 8 to move upward along the guide slot 12, so that the lower end of the limit plug 8 is removed from the limit slot 91. At this time, after the T-shaped connecting slide 9 loses the limit of the limit plug 8, the base 1 can be tilted toward the side of the opening of the T-shaped connecting slot 11, so that the four T-shaped connecting slides 9 can be moved from their respective positions. Slide out of the T-connecting slot 11 and remove the four pulleys 3 from the bottom of the base 1. Then slide the T-connecting slide 9 above the new pulley 3 into the four T-connecting slots 11 one by one, and make the T-connecting slide 9 slide into the innermost end of the T-connecting slot 11. Then manually rotate the adjusting handle 41 clockwise to drive the worm 4 to rotate, which can synchronously drive the four limit plugs 8 to move downward along the guide slot 12, so that the lower end of the limit plug 8 is inserted into the limit slot 91, and the T-connecting slide 9 is limited and fixed in the T-connecting slot 11 to complete the replacement of the pulley 3.
