Description

Technical Field

[0001] The utility model relates to the technical field of roller skates, in particular to a pair of roller skates with wheels that can be switched from an inline row to a double row. Background Art

[0002] Roller skates, commonly known as roller skates, originated in the Netherlands. They are a competitive sport using special roller skates as a tool, and are also a leisure activity. Roller skates, due to their gliding function, have become a popular means of transportation for everyday use. Existing ice skates are also increasingly popular among young children, leading to the emergence of single-row and double-row convertible roller skates. For example, Chinese utility model patent No. CN215841527U discloses a single-row and double-row convertible roller skate. A locking tongue in a locking device is lifted, compressing a spring, and the turntable is disengaged from the shoe base. The turntable can then be rotated. Once the turntable is fully rotated, the locking tongue is released and inserted into a locking hole under the action of the spring, locking the turntable to the shoe base. However, lifting the locking tongue is difficult for people with limited strength, especially children, making it difficult for such users (children) to operate. Therefore, improvements to the existing technology are necessary to address this problem. Utility Model Content

[0051] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0052] Example 1: See Figures 1 to 19A roller skate with wheels that can be switched from inline to double-row, comprising a shoe body 1 and a roller skating device 2 for roller skating provided on the lower end surface of the shoe body 1. The roller skating mechanism 2 comprises a front pulley device 21 and a rear pulley device 22 provided on the lower end surface of the shoe body 1. The front pulley device 21 and the rear pulley device 22 can be in contact with the ground, which is conducive to roller skating. The front pulley device 21 and the rear pulley device 22 have the same structure. The front pulley device 21 and the rear pulley device 22 both comprise a rotatable turntable 211 provided on the lower end surface of the shoe body 1. The upper end surface of the turntable 211 is provided with positioning blocks that are distributed in pairs and can rotate by themselves. 212, an automatic reset limiter 213 capable of moving back and forth is provided on the upper end surface of the turntable 211 between the relative positioning blocks 212, and an automatic return positioning assembly 214 capable of clamping the positioning block 212 is provided on the automatic reset limiter 213. A card slot 215 for cooperating with one end of each automatic reset limiter 213 is provided on the lower end surface of the shoe body 1, and a rotary switch 216 for opening and closing the automatic reset limiter 213 is provided on the lower surface of the turntable 211. A wheel frame 217 connected to the corresponding positioning block 212 is provided on the lower surface of the turntable 211, and a wheel 218 is provided on the wheel frame 217. One end of the automatic reset limiter 213 is located in the slot 215, so that the turntable 211 is in an original state where it cannot rotate. By turning the rotary switch 216 to the on state, one end of the automatic reset limiter 213 will be disengaged from the slot 215. After the automatic reset limiter 213 is disengaged from the restriction of the automatic return positioning component 214, the automatic return positioning component 214 is returned to its position, so that the automatic return positioning component 214 is disengaged from the restriction of the corresponding positioning block 212. In this way, rotating a single wheel frame 217 can make a single wheel frame 217 rotate, or rotating the wheel frames 217 distributed in pairs can achieve paired rotation. The distributed wheel frames 217 rotate simultaneously, and this switching by rotating the rotary switch 216 is not only conducive to realizing the switching of the front pulley device 21 and the rear pulley device 22 into a unified straight row or a unified double row, but also conducive to realizing the switching into one straight row and one double row in the front pulley device 21, and also conducive to the switching into one straight row and one double row in the rear pulley device 22 itself. The function is more satisfactory for use. More importantly, its design is convenient for users with less strength, especially children, to easily switch, and the operation is easier, simpler and more convenient, which is also more conducive to large-scale application and promotion.

[0053] Example 2: It can be explained based on Example 1, as shown in Figures 1 to 19As shown, the lower end surface of the shoe body 1 is provided with a groove for the rotation of the turntable 211. The inner side wall of the groove is provided with two engaging grooves 215. This facilitates the better engagement of one end of the automatic reset limiter 213 into the engaging groove 215. In this way, the rotation of the switch 216 can be connected to the automatic reset limiter 213 to achieve the rotation of the turntable 211 and prompt the automatic return positioning assembly 214 to control the opening and closing of the corresponding positioning block 212. Further, the two engaging grooves 215 are arranged at 90 degrees on the inner side wall of the groove, which facilitates the turntable 211 to achieve 90-degree rotation back and forth. The groove of the present invention is more conducive to the installation of the turntable 211, and it does not protrude, which better meets the production and user requirements. In addition, since two locking grooves 215 are provided on the inner side wall of the groove, this is conducive to the rotation of the rotary switch 216 to achieve the on and off states, which better meets the use requirements. In particular, when the rotary switch 216 is turned to the off state, one end of the automatic reset limiter 213 is locked in the locking groove 215, so that the turntable 211 cannot rotate. At the same time, the automatic reset limiter 213 will also lock the automatic return positioning component 214, and then the automatic return positioning component 214 will lock the corresponding positioning block 212, so that the wheel frame 217 connected to the positioning block 212 cannot rotate, which is conducive to the user's roller skating. Further explanation: a limit ring 219 is provided on the turntable 211. Specifically, the limit ring 219 is covered on the turntable 211, which is more conducive to the turntable 211 being able to rotate in the groove.

[0054] like Figures 1 to 19As shown, it is further explained that the rotary switch 216 includes a mounting hole 2161 that passes through the turntable 211, and the lower surface of the turntable 211 is provided with a blocking opening protrusion 2162 and a blocking closing protrusion 2163, and the lower surface of the turntable 211 is provided with a rotating body 2164, and a protrusion 2165 is provided on one side of the rotating body 2164. The protrusion 2165 rotates back and forth between the blocking opening protrusion 2162 and the blocking closing protrusion 2163, and an arc-shaped notch 2166 is provided on the circumference of the rotating body 2164, which is conducive to making the rotating body 2164 thick and thin. The rotating body 2164 is connected to the automatic reset limiter 213, which is conducive to the rotation of the rotating body 2164. When the protrusion 2165 rotates to block the opening protrusion 2162, the rotating body 2164 will prompt the automatic reset limiter 213 to move to the side away from the card slot 215, and the automatic reset limiter 213 will release the restriction on the automatic return positioning component 214. In this way, the automatic return positioning component 214 will also release the restriction on the relative positioning block 212, so that the front pulley device 21 and the rear pulley device 22 can be switched into a unified straight row or a unified double row, and it is also beneficial to realize the switching of the front pulley device 21 into one straight row and one double row, and it is also beneficial to switch the rear pulley device 22 itself into one straight row and one double row. The function is more satisfactory for use. More importantly, the design is convenient for users with less strength, especially children, to open and close the switch easily, making operation easier, simpler, and more convenient, which is also more conducive to large-scale application and promotion. The automatic reset limiter 213 automatically returns to its original position, causing one end of the automatic reset limiter 213 to snap into the slot 215, which is conducive to adjusting the thickness position and fixing it. When the protrusion 2165 rotates to block the closing protrusion 2163, it will cause one end of the automatic reset limiter 213 to snap into the slot 215, at which time neither the turntable 211 nor the rotating body 2164 can rotate. In this embodiment, the mounting hole 2161 adopts a football field shape (oval field shape), which facilitates the back-and-forth rotation of the rotating body 2164 to cause the automatic reset limiter 213 to slide back and forth.

[0055] Example 3: This can be explained based on Example 1 or Example 2, such as Figures 1 to 19As shown, the automatic reset limit member 213 includes a limit slider 2131 set on the turntable 211 and capable of sliding back and forth, a return member 2132 is set between the limit slider 2131 and the turntable 211, a limit groove 2133 is set on the turntable 211 to limit the back and forth movement of the limit slider 2131, and a notch 2134 is set on the turntable 211 on one side of the limit groove 2133, a block portion 2135 is set on one end of the limit slider 2131 to match the slot 215, and a return member 2132 is set on the limit slider 2131 in the limit groove 2133, and the limit slider 2131 is connected to the rotary switch 216 through a locking member. In this embodiment, the locking member is a bolt, a screw or a rivet. The rotation of the wheel frame 217 allows the limiting slider 2131 to slide back and forth along the limiting groove 2133, which facilitates the engagement or withdrawal of the block portion 2135 on one end of the limiting slider 2131 with the limiting groove 2133. After the external force disappears, the limiting slider 2131 can be urged back to its original position by the return member 2132. The limiting slider 2131 is provided with an automatic return positioning assembly 214. After the block portion 213 on one end of the limiting slider 2131 exits the limiting groove 2133, the limiting slider 2131 also releases the restriction of the automatic return limit member 213 on the paired positioning blocks 212, and the positioning blocks 212 can then be rotated by the rotation of the wheel frame 217, which facilitates the corresponding switching required by the user. The return member 2132 is a spring, which is widely available and easy to implement.

[0056] like Figures 1 to 19As shown, the limiting slider 2131 is a rectangular frame. The limiting slider 2131 of the rectangular frame is provided with recesses on the corresponding long sides in the longitudinal direction. In this embodiment, two recesses are provided on each long side. The recesses are used to locate and clamp the automatic return positioning assembly 214. The automatic return positioning assembly 214 includes correspondingly distributed latch sliders 2141. The relatively distributed latch sliders 2141 are connected by reset members 2142. This facilitates the relative distribution of the latch sliders 2141 to restore their original state. In this embodiment, two reset members 2142 are used, which further facilitates the reset of the latch sliders 2141. The reset members 2142 are springs, which are widely available and easy to implement. The locking member 212 is locked and the locking member 2132 is locked, so that the locking member 212 can be locked and the locking member 2132 can be locked.

[0057] like Figures 1 to 19 As shown, relatively distributed positioning plates 2111 are provided on the turntable 211 in the limiting groove 2133. The relatively distributed positioning plates 2111 can limit the movement of the latch slider 2141 toward the corresponding positioning block 212. In this embodiment, the relatively distributed latch slider 2141 moves back and forth in a vertical direction to the limiting slider 2131.

[0058] like Figures 1 to 19As shown, the positioning block 212 includes a positioning groove 2121 provided on the upper end surface of the turntable 211, the positioning groove 2121 is provided with an arcuate groove 2122, a rotatable positioning body 2123 is installed in the positioning groove 2121, and a limiting column 2124 is provided on the lower surface of the positioning body 2123 to slide back and forth in the arcuate groove 2122. At least two slots 2125 are provided on the circumference of the positioning body 2123 to engage with the latch slider 2141. This facilitates the back-and-forth rotation of the positioning body 2123 so that it can be stuck and prevented from rotating when not needed. The positioning body 2123 is connected to the wheel frame 217 by a fixing member, which facilitates the rotation of the positioning body 2123 driven by the wheel frame 217. Further, the circumference of the positioning body 2123 is provided with concave and convex shapes between adjacent slots 2125. This configuration facilitates the vibration of the positioning body 2123 during the rotation process driven by the wheel frame 217. In this embodiment, two slots 2125 are used, and a concave-convex shape is provided on the circumference of the positioning body 2123 between the two slots 2125, which is convenient for implementation. In this embodiment, the fixing member is a rivet, which is convenient for implementation.

[0059] Example 4: This can be explained based on Example 1, Example 2, or Example 3. Figures 1 to 19 As shown, the shoe body 1 includes a sole 11 and an upper 12 disposed on the sole 11. The sole 11 is provided with an adjustment member 13 that can cause the sole 11 and the upper 12 to move back and forth. By rotating the adjustment member 13 clockwise or counterclockwise, the sole 11 moves relative to the upper 12. In this way, the size of the roller skates can be adjusted by rotating the adjustment member 13. The adjustment method is simple and easy, and has strong versatility. The adjustment member 13 includes a screw rod 131 and a handle 132 disposed on the end face of the screw rod 131. The lower end face of the sole 11 is provided with a receiving groove. The receiving groove is used to accommodate the screw rod 131, thereby promoting the back and forth movement of the sole 11. This technical solution uses the existing shoe body 1 (that is, the toe cap in the prior art) for the foot to insert and wear. The prior art of this work station will not be discussed here one by one.

[0060] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the existing technology, which will not be described in detail here.

[0061] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments herein, or equivalent structural or equivalent process transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields are all included in the scope of protection of the present utility model patent.
