[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings.

[0022] Referring to Figures 1 to 5 , an embodiment of the present invention provides a wheel fixing device for roller skates. The roller skates include a bracket 1 and a plurality of rollers 2 mounted on the bracket 1. The wheel fixing device includes a wheel locking member 3 and a driving member 4. The driving member 4 is pivotally connected to the bracket 1. The driving member 4 and the wheel locking member 3 are connected by a transmission mechanism so that when the driving member 4 rotates, it can drive the wheel locking member 3 to move up and down. When the wheel locking member 3 moves downward, it presses against the rolling surface 21 of the roller 2 to lock the roller 2. The wheel fixing device further includes a locking mechanism capable of locking the wheel locking member 3 in the up and down direction.

[0023] When a beginner uses such roller skates, the driving member 4 can be rotated to drive the wheel locking member 3 to press against the rolling surface 21 of the roller 2, locking the roller 2. Then, the wheel locking member 3 is locked by the locking mechanism, so that the roller 2 remains in a locked state, facilitating the beginner to wear such roller skates to complete the standing action and adapt to the roller skates. After the beginner adapts to the roller skates, the locking mechanism can be unlocked, and then the driving member 4 is rotated in the reverse direction to separate the wheel locking member 3 from the roller 2, and the beginner can then normally learn roller skating.

[0024] Preferably, the transmission mechanism includes a gear 41 provided on the driving member 4 and a plurality of transmission teeth 31 provided on the wheel locking member 3 and meshing with the gear 41. The transmission teeth 31 are arranged at intervals in the up and down direction.

[0025] Referring to Figure 1 And Figure 3 , the bracket 1 includes a left side plate 11 and a right side plate 12 arranged at intervals. The wheel locking member 3 is arranged between the left side plate 11 and the right side plate 12. The right end of the driving member 4 is provided with a limit head 42 located on the right side of the right side plate 12. The left end of the driving member 4 passes through the right side plate 12 and extends into the space between the left side plate 11 and the right side plate 12.

[0026] Furthermore, the wheel locking member 3 is provided with a through hole 33 penetrating from left to right, and the left end of the driving member is received in the through hole 33.

[0027] Referring to Figure 3, the right side plate 12 is provided with a first through hole, and the driving member 4 is inserted through the first through hole so that the driving member 4 can rotate relative to the right side plate 12 and can also move left and right relative to the right side plate 12. The locking mechanism includes a plurality of card slots 421 spaced apart on the left end face of the limiting head 42, and a latch 121 provided on the right side face of the right side plate 12. When the latch 121 is inserted into the card slot 421, it can limit the rotation of the driving member 4. The locking mechanism further includes a fastener 5 movably provided on the left side plate 11. The right end of the fastener 5 is threadedly connected to the left end of the driving member 4. When the fastener 5 rotates relative to the driving member 4 in one direction, it drives the driving member 4 to move leftward so that the latch 121 is inserted into the card slot 421. When the fastener 5 rotates relative to the driving member 4 in the other direction, it drives the driving member 4 to move rightward so that the latch 121 disengages from the card slot 421.

[0028] Preferably, the fastener 5 is a screw. The left side plate 11 is provided with a second through hole. The head of the screw is located on the left side of the left side plate 11. The screw is inserted through the second through hole and can rotate and move left and right relative to the left side plate 11. The threaded end of the screw is threadedly connected to the left end of the driving member 4.

[0029] In a preferred embodiment of the present invention, a plurality of ratchet teeth 422 are provided on the left end face of the limiting head 42. Each ratchet tooth 422 is radially distributed around the axis of the driving member 4. The tooth grooves between adjacent ratchet teeth 422 form the card slot 421, so that when the latch 121 is inserted into the card slot 421, it can limit the upward movement of the locking wheel member 3. In this solution, in the initial state of the roller skate, the latch 121 is stuck in the card slot 421, and the head of the screw is in contact with or very close to the left side plate 11 to limit the rightward movement of the driving member 4. When the user needs to lock the roller 2, the driving member 4 can be rotated in one direction, so that the latch 121 moves along the inclined surface on the ratchet tooth 422 and switches to other card slots 421. During this process, the gear 41 of the driving member 4 meshes with the transmission teeth 31 on the pressing wheel member, driving the pressing wheel member to press down the roller 2 tightly. After pressing, the back surface of the ratchet tooth 422 abuts against the latch 121, locking the driving member 4, and then locking the pressing wheel member to prevent the pressing wheel member from loosening. When the user needs to unlock the roller 2, first loosen the screw, then move the driving member 4 to the right to disengage the card slot 421 from the latch 121, and then the driving member 4 can be rotated in the reverse direction to drive the pressing wheel member to move upward and disengage from the roller 2.

[0030] Further, the limiting head 42 is provided with a first screwing hole 423 into which a screwing tool can be inserted to screw the driving member 4, and the left end of the fastener 5 is provided with a second screwing hole 51 into which a screwing tool can be inserted to screw the fastener 5. The first screwing hole 423 and the second screwing hole 51 are generally arranged in a polygonal prism shape. Preferably, they are in the shape of a regular hexagonal prism, a regular triangular prism, or a regular quadrangular prism. Taking the regular hexagonal prism as an example, the corresponding screwing tool can be an internal hexagonal wrench. Using the screwing tool to screw the driving member 4 and the fastener 5 is convenient and labor-saving.

[0031] Further, the roller 2 is in a round drum shape, and the locking wheel member 3 is provided with a locking wheel arc surface 32 that can be fitted to the rolling surface 21. The locking wheel arc surface 32 can increase the contact area between the locking wheel member 3 and the roller 2, improving the locking effect.

[0032] Preferably, the number of the locking wheel arc surfaces 32 is two, and the two locking wheel arc surfaces 32 are respectively arranged at positions on the locking wheel member 3 corresponding to the two rollers 2.

[0033] The above is only the preferred implementation mode of the present invention. As long as the technical solutions that achieve the object of the present invention by basically the same means fall within the protection scope of the present invention.
