The shape is roughly the same as that of the shoe shell head 16, and the size of its bottom 31 is slightly smaller than that of the sole 12, so that the inner cover body 3 can move along the length direction of the skate in the cavity 13, and the inner cover 3 can move along the length of the skate. A shoe cavity 30 is defined between the body head 32 and the shoe shell heel 17 to accommodate the skater's foot, and the size of the shoe cavity 30 will change with the position of the inner sleeve in the cavity 13 .

In this embodiment, the sole 12 is provided with a midsole 11, and the midsole 11 also has a front portion 111 adjacent to the shoe shell head 16 and a rear portion 112 adjacent to the heel 17 of the shoe shell 1, and the inner sleeve The body 3 is placed on the front portion 111 of the midsole 11, and an insole 15 can be placed between the inner sleeve body 3 and the midsole 11; in addition, an insole can also be placed on the inner sleeve body 3.

The utility model is characterized by the design of the adjustment device 2; as shown in Figure 2 and Figure 3, the adjustment device 2 includes a screw sleeve 21 combined with the inner sleeve body 3 below, and a screw sleeve 21 screwed in the screw sleeve 21. A lead screw 22 and a pair of screw seats 23, 24 combined under the shoe sole 12; There is a space 141 for installing the adjusting device 2 in the space below the sole 12 at the front end, that is, in the front housing 140 of the skate 14 , as shown in FIG. 2 .

As shown in Fig. 3 and Fig. 4, the utility model is respectively provided with a slot 123, 113 at the front portion 121 of the sole 12 and the front portion 111 of the midsole 11, and the two slots 123, 113 are opposite up and down, and can be The screw sleeve 21 is provided to pass through so as to be combined under the inner sleeve body 3; in this embodiment, the distance between the two slots 123, 113 in the length direction of the skate is larger than that of the screw sleeve 21 to allow the screw sleeve 21 to It can move in the slot, and the screw sleeve 21 is combined with the screw 4 on the bottom 31 of the inner sleeve body 3, so that when the screw sleeve 21 moves, the inner sleeve body 3 will be driven to move in the chamber 13.

The inside of the screw sleeve 21 has a threaded hole 211 extending axially, and the lead screw 22 has a threaded portion 221 , a front end 222 and a rear end 223 , and the threaded portion 221 passes through the threaded hole 211 engagingly. , and the front end 222 and the rear end 223 on both sides of the threaded part 221 are not threaded, and there is an operation hole 224 in the front end of the lead screw 22. In this embodiment, the operation hole 224 can provide The hexagonal wrench fits into the hexagonal recess for insertion.

The pair of screw seats 23, 24 are oppositely combined under the sole 12 on both sides of the slot 123. In this embodiment, each screw seat is locked under the sole 12 with the screws 5 in the figure; the pair of screw seats 23 and 24 respectively have a shaft hole 231 and 241 penetrating in the axial direction to provide the front end 222 and the rear end 223 of the lead screw 22 to pass through correspondingly; A bearing 25 is set in the shaft hole 241 for receiving the rear end 223 of the lead screw 22, and a clip 26 is used to combine the lead screw 22 with the bearing 25, so that the axial direction of the lead screw 22 is positioned, That is to say, when the lead screw 22 rotates clockwise or counterclockwise, it will drive the screw sleeve 21 to move axially, and form an idle rotation by itself.

According to the skates formed by the utility model, as shown in Fig. 1 to Fig. 3, the adjusting device 2 is arranged in the lower space 141 of the front end of the shoe shell, and the lower space 141 is connected with an opening 142 through the front end of the skate 14. The external communication makes the operating tool 6 such as a hex wrench easily pass through the opening 142 and insert into the operating hole 225 of the front end 224 of the lead screw 22 to rotate the lead screw 22 of the adjusting device 2 .

Please refer to Fig. 2, shown in Fig. 4, when the shoe cavity 30 size of this skates will be adjusted, as long as the operation tool 6 is inserted into the operation hole of the front end of the adjustment device and rotated, the screw sleeve 21 can be moved, and then The inner sleeve body 3 can be adjusted according to the needs of the user to change the position of the inner sleeve body head 32 relative to the shoe shell heel 17, and the shoe cavity 30 defined by the inner sleeve body and the shoe shell heel Appropriate adjustments can be made.

Fig. 2 shows that the inner cover body 3 is at the position closest to the shoe shell head 16. At this time, the shoe cavity formed is the largest. Fig. 4 shows that the inner cover body 3 is at the position farthest from the shoe shell head 16. At this time, The formed shoe cavity is the smallest, and the inner sleeve body 3 can be adjusted in the range between the two positions, so that the size of the shoe cavity 30 of the skate can be adjusted most appropriately in response to the size of the user's foot; moreover, the The adjustment device 2 is very flexible and convenient in the implementation of the adjustment, and the user can achieve the adjustment purpose without wasting time and effort; in addition, the adjustment device 2 is arranged under the sole 12 of the skates, which is quite safe to use and will not affect wearing comfort, so the utility model has been able to achieve the desired design effect.

The foregoing description is only described for a specific preferred embodiment of the utility model, and does not limit the implementation of other variations or modified embodiments of the utility model. For example, the adjustment device 2 is not limited to be arranged on the center line of the shoe shell , and is not limited to be located at the front end of the shoe shell. Therefore, obvious replacements and modifications that can be made by those skilled in the art will still be incorporated within the patent scope claimed by the utility model.
