The first strip-shaped hole 103 further penetrates a locking pin 12, and both ends of the locking pin 12 can be formed into a rivet head outside the fixed seat by riveting, so that the rivet head is blocked on both sides of the fixed seat 1 respectively, thereby limiting the movement of the locking pin 12 along the first strip-shaped hole 103. Preferably, each pin shaft connected to the fixed seat 1 can be connected by this riveting method.

[0041] As shown in the drawings Figure 7 The middle of one end of wheel frame 2 is provided with a connecting pin 21 and a transmission pin 22, forming a structure in which the two ends of the transmission pin 22 and the two ends of the connecting pin 21 are fixed to two sheets respectively. The two sides of the other end of wheel frame 2 are connected to rotatable pulleys 23, and the other end of wheel frame 2 further penetrates a connecting shaft 24, which connects the two pulleys 23 through the two ends of the connecting shaft 24, so that the two pulleys 23 rotate around the connecting shaft 24 as the axis line. Referring again to the drawings Figure 1 And 2 The connecting pins 21 of the wheel frames 2 at both ends of the fixed seat 1 penetrate the fixed seat 1, so that the wheel frames 2 can only swing relative to the fixed seat 1, and the connecting pins 21 of the two wheel frames 2 are coaxial with the arc lines formed by the two arc-shaped holes 102 of the fixed seat 1 respectively. At the same time, the transmission pins 22 of the two wheel frames 2 penetrate the two arc-shaped holes 102 respectively, so that the transmission pins 22 of the two wheel frames 2 swing in the two arc-shaped holes 102 respectively with the connecting pins 21 as the axis, and the two wheel frames 2 form an arc structure relative to the fixed seat 1 as shown in the drawings Figure 1 And3 the expanded state and the attached Figure 8 and 9 the folded state.

[0042] as shown in the attached Figure 10 , the elastic member 4 is located in the accommodating slot 101 and is movable relative to the two wheel frames 2. Preferably, the bottom of the elastic member 4 is protruded to form two limiting portions 41, after the elastic member 4 is embedded into the accommodating slot 101, the transmission member 3 is sleeved outside the elastic member 4, and the bottom of the transmission member 3 is located on the two limiting portions 41 respectively, when the two ends of the transmission member 3 are connected to the wheel frames 2 at the two ends of the fixed seat 1 and are limited, the two limiting portions 41 of the elastic member 4 are limited between the bottom of the transmission member 3 and the bottom surface of the accommodating slot 101, and can only be substantially movable relative to the two wheel frames 2. The side surface of the elastic member 4 is also provided with a second strip-shaped hole 401 which is inclined relative to the first strip-shaped hole 103, and the locking pin 12 passes through the second strip-shaped hole 401. After the structure is adopted, when the elastic member 4 moves, the second strip-shaped hole 401 can push the locking pin 12 to ascend and descend relative to the first strip-shaped hole 103, that is, the movement of the elastic member 4 can drive the locking pin 12 to ascend and descend relative to the first strip-shaped hole 103.

[0043] further, as shown in the attached Figure 3 and 9 , a protruding elastic rib 13 is arranged in the fixed seat 1 at the bottom of the accommodating slot 101, the elastic rib 13 is inclined upward and towards the direction where the elastic member 4 is arranged, and the elastic rib 13 abuts against the end of the elastic member 4 which is away from the adjusting pin. When the adjusting pin 5 is pushed into the fixed seat 1, the elastic member 4 moves and abuts against the elastic rib 13, the elastic rib 13 is lifted up, and the elastic force of the elastic rib 13 when it is reset can push the elastic member 4 to reset automatically.

[0044] One end of the adjusting pin 5 passes into the fixed seat 1 and is connected to the elastic member 4, the connection mode can be as shown in the attached Figure 5 , 10 and 11, the elastic member 4 is provided with a connecting slot 402, the connecting slot 402 forms an aperture 403 at the end surface of the elastic member 4, the width of the aperture 403 is smaller than the internal width of the connecting slot 402, the ring surface of the adjusting pin 5 close to the end is provided with a ring-shaped slot 501, the ring-shaped slot 501 is adapted to be clamped in the aperture 403, and the end of the adjusting pin 5 is located in the connecting slot 402, when the cover plate 11 covers the fixed seat 1 and limits the adjusting pin 5 to be movable only relative to the fixed seat 1, the end of the adjusting pin 5 is simultaneously limited to be unable to move out of the connecting slot 402, and the adjusting pin 5 is rotatable relative to the elastic member 4.

[0045] In addition, one side of the surface of the adjusting pin 5 is provided with a protrusion forming a blocking part 51, the width of the blocking part 51 is smaller than the outer diameter of the adjusting pin 5, the end surface of the fixing base 1 is provided with a first slot 105 and a second slot 106 in communication, the width of the first slot 105 is greater than the width of the second slot 106, and the width of the second slot 106 is greater than the width of the blocking part 51. One end of the adjusting pin 5 is adapted to pass through the first slot 105, and the elastic member 4 is connected in the above manner. After the cover plate 11 is fixed to the fixing base 1 to cover the upper end of the first slot 105, the adjusting pin 5 can be limited to only extend and retract in the containing groove 101 of the fixing base 1. When the adjusting pin 5 is rotated to correspond to the blocking part 51 and the second slot, the blocking part 51 can pass into the second slot 106, so that the adjusting pin 5 can move relative to the fixing base 1 and drive the elastic member 4 to move, thereby realizing the lifting movement of the locking pin 12 relative to the first slot 103. When the adjusting pin 5 is rotated to misalign the blocking part 51 and the second slot, the blocking part 51 is blocked outside the end surface of the fixing base 1, so that the adjusting pin 5 cannot move relative to the fixing base 1 to fix the elastic member 4.

[0046] Referring again to the drawings Figure 12 Further, the two ends of the transmission member 3 are respectively provided with transmission pins 22 of the two wheel frames 2, so that the two ends of the transmission member 3 are respectively connected to the two wheel frames 2. When the transmission member 3 moves, the two wheel frames 2 can swing around the connecting pin 21 as the axis, thereby forming an unfolded or folded state. Further, the position of the transmission member 3 between the two transmission pins 22 is further provided with a first clamping groove 301 and a second clamping groove 302, and the transmission member 3 is further connected to an elastic member 31, which can be a spring. One end of the elastic member 31 is hooked in the fixing base 1, and specifically can hook the connecting pin 21 of one of the two wheel frames 2. The other end of the elastic member 31 is hooked in the connecting hole 303 of the transmission member 3. In this structure, the elastic force formed by the elastic member 31 pulls the transmission member 3 away from the locking pin 12, so that the first clamping groove 301 or the second clamping groove 302 clamps the locking pin 12 falling below the first slot 103, thereby fixing the transmission member 3, and further fixing the two wheel frames 2 connected to the two ends of the transmission member 3 relative to the fixing base 1, avoiding loosening of the wheel frames 2. That is, the two wheel frames 2 can be kept in a fixed state after unfolding or folding. Specifically, when the two wheel frames 2 are unfolded relative to the fixing base 1, the transmission member 3 moves to the first clamping groove 301 to clamp the locking pin 12. When the two wheel frames 2 are folded relative to the fixing base 1, the transmission member 3 moves to the second clamping groove 302 to clamp the locking pin 12. Through the clamping of the first clamping groove 301 and the second clamping groove 302 to the locking pin 12, the fixed state of the transmission member 3 relative to the fixing base 1 can be further improved, thereby improving the stability of the two wheel frames 2, avoiding accidents caused by automatic and sudden swinging of the wheel frames 2 during sliding.

[0047] After the above structure is adopted, the working mode of the folding mechanism of the utility model is as follows:

[0048] As shown in the accompanying Figure 8 and 9 , when the pulley 23 needs to be retracted, after rotating the adjusting pin 5 to the second notch 106 corresponding to the blocking part 51, the adjusting pin 5 is pushed into the fixed seat 1, the elastic member 4 is moved forward to drive the locking pin 12 to rise to the first clamping groove 301, and the elastic member 4 is pushed up to the elastic spring 13, at this time, the transmission member 3 is not limited by the locking pin 12 and can be moved, so that the wheel frame 2 can be pushed to embed the pulley 23 in the gap slot, in the process, the elastic member 31 is elongated, and after the two wheel frames 2 are retracted, the second clamping groove 302 corresponds to the first slot 103, at this time, the elastic spring 13 is reset to push the elastic member 4 back, so that the locking pin 12 falls to be clamped in the second clamping groove 302, so that the transmission member 3 is clamped and fixed, and then the two wheel frames 2 are retracted and kept in a fixed state.

[0049] As shown in the accompanying Figure 1 and 3 , when the pulley 23 needs to be retracted, after rotating the adjusting pin 5 to the second notch 106 corresponding to the blocking part 51, the adjusting pin 5 is pushed into the fixed seat 1, the elastic member 4 is moved forward to drive the locking pin 12 to rise to the first clamping groove 301, and the elastic member 4 is pushed up to the elastic spring 13, at this time, the transmission member 3 is not limited by the locking pin 12 and can be moved, so that the wheel frame 2 can be pushed to embed the pulley 23 in the gap slot, in the process, the elastic member 31 is elongated, and after the two wheel frames 2 are retracted, the second clamping groove 302 corresponds to the first slot 103, at this time, the elastic spring 13 is reset to push the elastic member 4 back, so that the locking pin 12 falls to be clamped in the second clamping groove 302, so that the transmission member 3 is clamped and fixed, and then the two wheel frames 2 are retracted and kept in a fixed state.

[0050] From the above operation mode, the pulley 23 can be retracted in the shoe sole relatively quickly, and the pulley 25 can be automatically popped out of the shoe sole by pressing the adjusting pin 5, so that the pulley 23 is quickly expanded, and the operation convenience is greatly improved.

[0051] As shown in the accompanying Figure 13As shown, the roller skate provided with the folding mechanism includes a sole 61, the sole 61 is provided with a mounting groove 601, the fixing base 1 is embedded and fixed in the mounting groove 601 so that the folding mechanism is wholly accommodated in the sole 61, further, the fixing base 1 extends outwardly at the side of the opening position of the accommodating groove 101 to form a fixing plate 14, the mounting groove 601 is provided with a step 603 at the upper end position of the sole 61, when the fixing base 1 is embedded in the mounting groove 601, the fixing plate 14 is adapted to be clamped on the step 603, and the fixing plate 14 and the step 603 are fixed in the sole 61 by adhesive. The sole 61 is provided with a pulley groove 602 at both sides of the mounting groove 601, when the two wheel frames 2 are in the folded state relative to the fixing base 1, the pulley 23 is embedded in the pulley groove 602, so that the pulley 23 is hidden in the shoe, and the normal walking is not affected.

[0052] Referring to the drawings again Figure 14 The sole 61 is provided with an operation hole 604 at the heel position, the adjusting pin 5 is passed through the operation hole 604 to the outside of the shoe at the end far away from the elastic member 4. When it is needed to fold or unfold the pulley 23, the adjusting pin 5 is only needed to be rotated and pressed at the heel position of the shoe, which is very convenient.

[0053] The above is only the specific embodiment of the present application, but the design concept of the present application is not limited to this, any non-substantial change of the present application by using the concept should belong to the behavior of infringing the protection range of the present application.
