[0038] Reference Figure 1As shown, the roller skate assembly structure according to an embodiment of the present invention includes a shoe shell 100 and a foot strap 200; the foot strap 200 is rotatably connected to the shoe shell 100, and the foot strap 200 can rotate relative to the shoe shell 100 between a first position and a second position; when in the first position, the foot strap 200 is engaged with the shoe shell 100 to fix the foot strap 200 to the shoe shell 100; when in the second position, the foot strap 200 is not engaged with the shoe shell 100 so that the foot strap 200 can be removed from the shoe shell 100.

[0039] The foot strap 200 can be installed or removed simply by driving the foot strap 200 to rotate. No additional tools are required to install or remove the foot strap 200, making it convenient for users to replace it.

[0040] When installing the foot strap 200, install the foot strap 200 on the shoe shell 100, and then drive the foot strap 200 to rotate to the first position so that the foot strap 200 is engaged with the shoe shell 100, thereby fixing the foot strap 200 on the shoe shell 100.

[0041] When the foot strap 200 is removed, drive the foot strap 200 to rotate to the second position so that the foot strap 200 is not locked to the shoe shell 100, and then the foot strap 200 can be removed from the shoe shell 100, thus completing the removal of the foot strap 200.

[0042] In some embodiments of this utility model, such as Figure 1 As shown, it also includes a strap 300, which is detachably mounted on the shoe shell 100 for easy replacement by the user.

[0043] In a further embodiment of this utility model, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, one of the strap 300 and the shoe shell 100 has a first engaging groove 110, and the other of the strap 300 and the shoe shell 100 has a first engaging portion 310. A portion of the first engaging portion 310 is rotatably placed within the first engaging groove 110, and the other portion of the first engaging portion 310 is located outside the first engaging groove 110. The strap 300 can rotate between a third position and a fourth position. When the strap 300 is in the third position, as shown in Figures 3, 4, and 5, the strap 300 is rotated between a third position and a fourth position. Figure 5 As shown, another part of the first snap-fit ​​portion 310 snaps into the first snap-fit ​​slot 110; when the strap 300 is in the fourth position, as Figure 4 As shown, the first card connector 310 can be removed from the first card connector slot 110.

[0044] The strap 300 and the shoe shell 100 adopt the above structure so that the installation or removal of the strap 300 only requires driving the strap 300 to rotate, and the installation or removal of the strap 300 can be achieved without additional tools, making it convenient for users to replace.

[0045] like Figure 2 , 3As shown, taking the strap 300 having a first snap-fit ​​portion 310 and the shoe shell 100 having a first snap-fit ​​groove 110 as an example;

[0046] When installing strap 300, strap 300 is in the fourth position, such as... Figure 4 As shown, a portion of the first latching part 310 is inserted into the first latching slot 110, while the other portion of the first latching part 310 is positioned outside the first latching slot 110. Then, the strap 300 is driven to rotate, causing the strap 300 to rotate the first latching part 310 to the third position. Figure 5 As shown, the other part of the first snap-fit ​​portion 310 is snapped into the first snap-fit ​​through groove 110, thereby fixing the strap 300 to the shoe shell 100.

[0047] When the strap 300 is removed, drive the strap 300 to rotate in the opposite direction, causing the strap 300 to rotate the first locking part 310 to the fourth position, such as... Figure 4 As shown, the other part of the first snap-fit ​​portion 310 is not snapped into the first snap-fit ​​slot 110, so that the strap 300 can be removed from the shoe shell 100, thus completing the disassembly of the strap 300.

[0048] Specifically, such as Figure 1 , 3 As shown, the shoe shell 100 has a first receiving groove 140 on the side of the first snap-fit ​​groove 110, so that the other part of the first snap-fit ​​portion 310 can be placed in the first receiving groove 140, avoiding the other part of the first snap-fit ​​portion 310 from protruding and affecting the aesthetics of the shoe shell 100.

[0049] Specifically, such as Figure 4 , 5 As shown, the first snap-fit ​​portion 310 includes a first cylinder 311 and a plurality of first extension portions 312 disposed on the side wall of the first cylinder 311. The plurality of first extension portions 312 are spaced apart along the circumferential direction of the first cylinder 311. The shape of the first snap-fit ​​groove 110 matches the shape of the first snap-fit ​​portion 310. The first snap-fit ​​groove 110 includes a first slot 111 that matches the shape of the first cylinder 311 and a second slot 112 that matches the shape of the first extension portion 312. The first extension portion 312 is another part of the first snap-fit ​​portion 310.

[0050] During installation, first rotate the strap 300 degrees to the fourth position, such as... Figure 4 As shown, the first extension 312 of the first latching portion 310 is aligned with the second slot 112 of the first latching groove 110, so that the first latching portion 310 can be inserted into the first latching groove 110, and the first extension 312 is positioned outside the first latching groove 110. Then, the strap 300 is driven to rotate to the third position, as shown. Figure 5As shown, the first extension 312 of the first snap-fit ​​portion 310 is misaligned with the second slot 112 of the first snap-fit ​​groove 110, so that the first snap-fit ​​portion 310 cannot detach from the first snap-fit ​​groove 110, and the strap 300 is fixed to the shoe shell 100, thereby realizing the installation of the strap 300.

[0051] When removing, rotate the strap 300 degrees to the fourth position, as shown. Figure 4 As shown, the first extension 312 of the first snap-fit ​​portion 310 is aligned with the second slot 112 of the first snap-fit ​​groove 110, so that the first snap-fit ​​portion 310 can be removed from the first snap-fit ​​groove 110, thereby realizing the disassembly of the strap 300.

[0052] Specifically, one end of the strap 300 is provided with a first snap-fit ​​part 310, and one end of the strap 300 is installed on the left side of the shoe shell 100 through the first snap-fit ​​part 310. The other end of the strap 300 can be connected to the fixing part on the right side of the shoe shell 100 to tie the foot.

[0053] In a further embodiment of the present invention, one of the foot strap 200 and the shoe shell 100 has a second locking groove 120, and the other of the foot strap 200 and the shoe shell 100 has a second locking portion 210. A portion of the second locking portion 210 is rotatably placed in the second locking groove 120, and the other portion of the second locking portion 210 is located outside the second locking groove 120. When the foot strap 200 is in the first position, the other portion of the second locking portion 210 is engaged with the second locking groove 120. When the foot strap 200 is in the second position, the second locking portion 210 can be removed from the second locking groove 120.

[0054] The foot strap 200 and the shoe shell 100 adopt the above structure, which makes it easy to install and remove the foot strap 200 without the need for tools.

[0055] Specifically, the structure of the second card slot 120 is the same as that of the first card slot 110, and the structure of the second card part 210 is the same as that of the first card part 310. Therefore, the installation and disassembly principles of the strap 200 can be referred to the installation and disassembly principles of the strap 300.

[0056] Specifically, such as Figure 1 , 3 As shown, the shoe shell 100 has a second receiving groove 150 on the side of the first snap-fit ​​groove 110, so that the other part of the second snap-fit ​​portion 210 can be placed in the second receiving groove 150, avoiding the other part of the second snap-fit ​​portion 210 from protruding and affecting the aesthetics of the shoe shell 100.

[0057] Specifically, the foot strap 200 has a second locking part 210 on both the left and right sides of the bottom, and the foot strap 200 is rotatably installed on the left and right sides of the shoe shell 100 through the second locking part 210.

[0058] In some embodiments of this utility model, such as Figure 6 , 7 As shown, it also includes a bracket 400 for mounting pulleys. The top of the bracket 400 has a groove 410 with an opening on one side. The bottom of the shoe shell 100 has a first slider portion 130. The first slider portion 130 can be inserted into the groove 410 from the opening and engage with the groove 410 to facilitate replacement of the bracket 400.

[0059] In a further embodiment of this utility model, such as Figure 7 As shown, multiple slide grooves 410 are provided, spaced apart in the front-to-back direction. The number of first slider parts 130 is the same as the number of slide grooves 410, and their positions correspond one-to-one. At least one first slider part 130 has a mounting cavity 131. The side wall of the mounting cavity 131 is connected to an elastic member 132 that can deform under force in the vertical direction. A portion of the elastic member 132 protrudes downward from the mounting cavity 131. At least one slide groove 410 has a notch 411 at its bottom. Figure 8 As shown, when the first slider part 130 is located in the slide groove 410, the elastic member 132 can engage with the side wall of the notch 411 so that the notch 411 can prevent the first slider part 130 from being removed from the slide groove 410.

[0060] The first slider part 130 is provided with an elastic element 132 that can deform under force in the vertical direction, and the groove 410 is provided with a notch 411 so that when the bracket 400 is installed, the bracket 400 can automatically engage with the shoe shell 100, and when disassembling, it is only necessary to drive the elastic element 132 to deform upward, making the bracket 400 easy to install and disassemble.

[0061] Specifically, such as Figure 6 , 7 As shown, there are two slide grooves 410, which are spaced apart in the front-back direction and the openings of both slide grooves 410 are located on the rear side of the slide grooves 410. There are also two first slider parts 130. The slide groove 410 located at the rear is provided with a notch 411, and the first slider part 130 located at the rear is provided with a mounting cavity 131. An elastic member 132 is connected to the rear side wall of the mounting cavity 131.

[0062] During installation, the drive shoe shell 100 moves forward, causing the two first slider parts 130 to move forward and insert into the groove 410 through the opening. During insertion, the bottom of the groove 410 causes the elastic element 132 to bend upward, positioning it within the mounting cavity 131. When the first slider part 130 moves to the position where the elastic element 132 aligns with the notch 411, as... Figure 8 As shown, the elastic element 132 elastically recovers, extends out of the mounting cavity 131 and abuts against the rear side wall of the notch 411. The notch 411 prevents the elastic element 132 from moving backward, thereby preventing the shoe shell 100 from moving backward relative to the bracket 400, thus fixing the shoe shell 100 to the bracket 400.

[0063] During disassembly, the drive elastic element 132 bends and deforms upward, causing the elastic element 132 to leave the notch 411, and thus the shoe shell 100 can be removed from the bracket 400.

[0064] In some embodiments of this utility model, such as Figure 6 , 8 As shown, the bottom of the groove 410 has an inclined surface 420 on the side near the notch 411, which facilitates the engagement of the elastic member 132 with the side wall of the notch 411. By providing the inclined surface 420, the elastic member 132 can better extend out of the mounting cavity 131, making it easier for the elastic member 132 to engage with the notch 411.

[0065] Specifically, the inclined surface 420 is located on the front side of the notch 411.

[0066] In some embodiments of this utility model, such as Figure 8 As shown, the mounting cavity 131 extends through the shoe shell 100 in the vertical direction, allowing the user to drive the elastic element 132 to deform from the top or bottom of the shoe shell 100, making it easier to install and remove the bracket 400.

[0067] In some embodiments of this utility model, such as Figure 1 , 9 As shown, it also includes a buckle base 500, which is snapped together with the foot strap 200 for easy installation and removal of the buckle base 500.

[0068] Specifically, the buckle base 500 is installed on the left side of the foot strap 200, and the buckle clip is installed on the right side of the foot strap 200. The buckle base 500 is connected to one end of the buckle. When it is necessary to tie the foot with the foot strap 200, the other end of the buckle is connected to the buckle clip to tighten the buckle.

[0069] In a further embodiment of this utility model, such as Figure 9 As shown, the bottom of the buckle base 500 is provided with a second slider portion 510 with a T-shaped cross-section, as... Figure 10As shown, the side wall of the foot strap 200 has a third locking groove 220, which includes a removable section 221 and a locking section 222 located in front of the removable section 221, as shown. Figure 1 As shown, the second slider portion 510 is movably disposed within the third card slot 220;

[0070] The second slider 510 is capable of moving between the fifth position and the sixth position;

[0071] When the second slider part 510 is in the fifth position, such as Figure 12 , 13 As shown, the second slider part 510 is engaged with the snap-fit ​​section 222, and the second slider part 510 is engaged with the rear side of the pull-out section 221, so that the buckle base 500 is fixed on the binding foot 200.

[0072] When the second slider portion 510 is in the sixth position, the second slider portion 510 located on the third locking groove 220 can be moved out from the removal section 221.

[0073] This allows the buckle base 500 to be installed and removed without additional tools.

[0074] Specifically, such as Figure 9 , 10 As shown in Figure 13, the second slider part 510 includes a first connecting section 511 and a second connecting section 512. One end of the first connecting section 511 is fixedly connected to the buckle base 500, and the other end of the second connecting section 512 is fixedly connected to the first connecting section 511. The length of the second connecting section 512 in the front-back direction is greater than the length of the first connecting section 511 in the front-back direction, and the width of the second connecting section 512 in the vertical direction is greater than the width of the first connecting section 511 in the vertical direction. The width of the moving section 221 in the vertical direction is greater than the width of the second connecting section 512 in the vertical direction, and the width of the locking section 222 in the vertical direction is greater than the width of the first connecting section 511 in the vertical direction and less than the width of the second connecting section 512 in the vertical direction. By adopting the above-mentioned size design of the second slider part 510 and the third locking groove 220, it is ensured that the second slider part 510 can be locked with the third locking groove 220, and also ensures that the second slider part 510 can be moved out of the third locking groove 220.

[0075] During installation, such as Figure 9 , 10 As shown, the second connecting segment 512 is inserted forward into the removing segment 121, and the first connecting segment 511 is located within the snap-fit ​​segment 222, causing the second slider portion 510 to move forward along the snap-fit ​​segment 222. When the second slider portion 510 moves to the sixth position and then moves backward to the fifth position, as shown... Figure 13As shown, the first connecting section 511 is completely located within the third snap-fit ​​slot 220, and the second connecting section 512 snaps into the snap-fit ​​section 222 and also snaps into the rear side of the removal section 121, thereby fixing the buckle base 500 onto the foot 200.

[0076] During disassembly, the second slider 510 moves forward and to the sixth position, so that the second connecting section 512 is located inside the removal section 121, so that the second connecting section 512 is not engaged with the rear side of the removal section 121, thereby driving the second connecting section 512 to move backward, so that the second connecting section 512 is removed from the removal section 121, thereby allowing the entire second slider 510 to move backward, so that the buckle base 500 is removed from the third engaging slot 220.
