Description

Technical Field

[0001] This invention relates to a stroller, and more particularly to an easy-to-assemble and disassemble wheel with a simple structure and quick and convenient installation and disassembly. Background Technology

[0002] Current strollers typically come with four wheels: two swivel wheels in the front and two fixed wheels in the rear. All four wheels are pivotally connected to wheel seats, which are directly fixed to the frame's support legs. However, since the wheels are made of rubber, they wear out after a period of use and require replacement. The wheel connection method is not convenient, making manual replacement impossible for ordinary users. For example, the commonly used hairpin wheels require tools for disassembly and installation, which is cumbersome, difficult to maintain, and inconvenient for the average user. Summary of the Invention

[0003] The primary objective of this invention is to provide an easy-to-assemble and disassemble wheel that is simple in structure and quick and convenient to install and disassemble.

[0004] The second objective of this invention is to provide an easy-to-assemble and disassemble wheel with a simple structure and quick and convenient installation and disassembly.

[0005] The third objective of this invention is to provide an easy-to-assemble and disassemble wheel with a simple structure and quick and convenient installation and disassembly.

[0006] The fourth objective of this invention is to provide an easy-to-assemble and disassemble wheel with a simple structure and quick and convenient installation and disassembly.

[0007] To achieve the above objectives, the present invention provides an easy-to-install and detachable wheel comprising a wheel, a swivel, and a locking component. The wheel has a mounting hole at its center, and one end of the swivel has a receiving groove. The locking component is movably fastened to the receiving groove. The locking component can swing between a first position and a second position. When the locking component is in the first position, the locking component and the swivel can pass through the mounting hole of the wheel. When the locking component is in the second position, the swivel and the wheel are connected and locked.

[0008] Compared with existing technologies, this invention features a locking component that movably engages with the connecting part of the axle. When the wheel is connected to the axle, the locking component can swing to either a first or a second position. In the first position, the locking component and the axle can pass through the wheel's mounting hole, allowing for wheel removal. In the second position, the locking component is engaged with the mounting hole, preventing the wheel from detaching from the axle and thus locking the wheel in place. Therefore, wheel installation and removal can be quickly achieved simply by operating the locking component; the structure is simple, and maintenance and use are very convenient.

[0009] Preferably, the receiving groove extends through both sides and the end face of the rotating shaft, and a connecting part is provided inside the receiving groove, the connecting part passing through the engaging member.

[0010] Preferably, the first position is when the engaging member swings to the same direction as the extension direction of the central axis of the rotating shaft; the second position is when the engaging member swings to the point where its length direction intersects the extension direction of the central axis of the rotating shaft, and the engaging member abuts against the edge of the mounting hole.

[0011] Preferably, the engaging component has a long, circular structure.

[0012] Specifically, an elongated hole is formed in the middle of the engaging part, and an engaging position is provided in the middle of the elongated hole. When the shaft and the wheel are locked, the connecting part engages in the engaging position.

[0013] Preferably, the connecting part is a connecting shaft.

[0014] Preferably, the easy-to-install wheel also includes a wheel cover that covers one side of the wheel to conceal the locking mechanism. The inner side of the wheel cover has locating ribs for positioning the locking mechanism.

[0015] An easy-to-install and detachable wheel includes a wheel, a shaft, a locking element, and an elastic element. The wheel has a mounting hole at its center, and one end of the shaft has a locking groove that allows the shaft to extend into or retract from the mounting hole. The locking element is movably disposed on one side of the wheel. The elastic element provides an elastic force that engages the locking element in the locking groove, thereby locking the shaft and the wheel together. When the locking element disengages from the locking groove, the shaft and the wheel can be released and separated.

[0016] Compared with existing technologies, this invention features a locking component that is movably mounted on the wheel. When the wheel is connected to the axle, the locking component moves to the locking groove on the axle and engages with it, thus locking the wheel and axle. When the locking component moves out of the locking groove, it releases the wheel and axle. Therefore, the wheel can be quickly installed and removed simply by operating the locking component. The structure is simple, and maintenance and use are very convenient.

[0017] Preferably, the engaging component has an elongated hole through which the rotating shaft passes, with a first engaging position at one end and a second engaging position at the other end, the first engaging position and the second engaging position having different curvatures.

[0018] Specifically, the diameter of the arc-shaped edge of the first engaging position is smaller than the diameter of the rotating shaft, while the diameter of the arc-shaped edge of the second engaging position is larger than the diameter of the rotating shaft. This allows the rotating shaft to engage with the edge of the first engaging position when it is in the first engaging position, and to pass directly through the second engaging position and disengage from the engaging component when it is in the second engaging position, thus achieving the purpose of locking or unlocking.

[0019] Preferably, one end of the engaging component is pivotally connected to one side of the wheel, and the other end is provided with an engaging position. After the engaging component rotates in one direction, it engages into the engaging groove, and after the engaging component rotates in another direction, it disengages from the engaging groove.

[0020] Preferably, a pushing part extends from one side of the engaging component. The easily detachable wheel also includes a wheel cover, which is slidably disposed in the middle of the wheel and has a driving part. Pressing the wheel cover causes the driving part to drive the pushing part. The wheel cover serves two purposes: it can conceal the engaging component, making the wheel more aesthetically pleasing, and it can also function as an operating element for manipulating the engaging component, thereby improving ease of operation.

[0021] Specifically, the drive unit has a drive ramp, and the push unit has a mating ramp, with the drive ramp and the mating ramp sliding against each other. By utilizing the drive ramp and the mating ramp, the wheel cover can drive the engagement parts to move more smoothly, further improving the ease of operation.

[0022] An easy-to-install and detachable wheel includes a wheel, a swivel, and a locking component. The wheel has a mounting hole at its center, and one end of the swivel has a locking groove, allowing the swivel to extend into or retract from the mounting hole. The locking component is located on one side of the wheel and has an elastic portion. The elastic portion elastically engages with the locking groove, allowing the swivel to be connected and locked to the wheel.

[0023] Compared with existing technologies, this invention features a locking component with an elastic part at one end. Utilizing the resilient nature of this part, when in its natural state, it springs back and engages with the locking groove of the axle, thus locking the axle to the wheel. When the elastic part is opened under force, it disengages from the locking groove, releasing the axle from the wheel, thereby achieving the purpose of unlocking both the wheel and the axle. Therefore, wheel installation and removal can be quickly accomplished simply by operating the elastic part; the structure is simple, and maintenance and use are very convenient.

[0024] Preferably, the engaging component includes a U-shaped structure with elastic portions formed at both ends of the U-shaped structure.

[0025] Preferably, the easy-to-install wheel also includes an operating element that is slidably disposed on one side of the wheel to push the elastic part away from the engagement groove. This improves the ease of operation.

[0026] Specifically, a guide portion extends from the end of the elastic part, and the operating member has an oblique hole. The guide portion is slidably disposed within the oblique hole to drive the elastic part to open. By providing the guide portion, the operating member can more easily drive the elastic part to move, thereby improving the convenience of operation.

[0027] Preferably, the easy-to-install wheel also includes a wheel cover, which is located on one side of the wheel and covers the operating components. The wheel cover conceals the locking mechanism, thus making the wheel appear more aesthetically pleasing.

[0028] An easily detachable wheel includes a wheel, a swivel, a locking element, and an elastic element. The center of the wheel is fixedly connected to one end of the swivel. The other end of the swivel is provided with a locking groove and can extend into or retract from a support leg of the frame. The locking element is movably disposed on the support leg. The elastic element provides an elastic force that engages the locking element in the locking groove, thereby locking the swivel and the support leg. When the locking element disengages from the locking groove, the swivel and the support leg can be released and separated.

[0029] Compared with existing technologies, this invention uses a locking component to connect the wheel to the axle. The locking component is movably mounted on the support leg. When the axle is connected to the support leg, the locking component can move to the locking groove of the axle and engage with it, thus locking the wheel. When the locking component moves out of the locking groove, the wheel is released. Therefore, the wheel can be quickly installed and removed simply by operating the locking component. The structure is simple, and maintenance and use are very convenient.

[0030] Preferably, the engaging component has an elongated hole through which the rotating shaft passes, with a first engaging position at one end and a second engaging position at the other end, the first engaging position and the second engaging position having different curvatures.

[0031] Specifically, the diameter of the arc-shaped edge of the first engaging position is smaller than the diameter of the rotating shaft, while the diameter of the arc-shaped edge of the second engaging position is larger than the diameter of the rotating shaft. This allows the rotating shaft to engage with the edge of the first engaging position when it is in the first engaging position, and to pass directly through the second engaging position and disengage from the engaging component when it is in the second engaging position, thus achieving the purpose of locking or unlocking.

[0075] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0076] like Figures 1 to 7 As shown in the figure, the structure of Embodiment 1 of the present invention is illustrated below:

[0077] Please see Figures 1 to 3 The easily detachable wheel 100 of this embodiment includes a wheel 110, a pivot 120, and a locking member 130. The wheel 110 has a receiving cavity 111 in its middle, and a mounting hole 112 at the center of the receiving cavity 111. One end of the pivot 120 has a receiving groove 121 that extends through both sides and the end face, and the other end of the pivot 120 is connected to the frame. A connecting part 122 is provided within the receiving groove 121, and the connecting part passes through the locking member 130; the connecting part 122 is a connecting shaft. The locking member 130 is movably fastened to the receiving groove 121; the locking member 130 can swing between a first position and a second position. When the locking member 130 is in the first position, the locking member 130 and the pivot 120 can pass through the mounting hole 112 of the wheel; when the locking member 130 is in the second position, the pivot 120 and the wheel 110 are locked together. The first position is that the engaging member 130 swings so that its length direction is in the same direction as the extension direction of the central axis of the rotating shaft 120; the second position is that the engaging member 130 swings so that its length direction intersects the extension direction of the central axis of the rotating shaft 120, and the engaging member 130 abuts against the edge of the mounting hole 112.

[0078] For example Figure 3As shown, the engaging member 130 has an elongated, circular structure. An elongated hole 131 is formed in the center of the engaging member 130, with an engaging position 132 in the center of the elongated hole 131 and arc-shaped holes 133 on both sides. When the rotating shaft 120 is locked to the wheel 110, the connecting part 122 engages with the engaging position 132. Specifically, one side of the engaging member 130 has a pleated structure forming the engaging position 132, and this side has a certain elasticity. When the connecting part 122 reaches the pleated structure, the pleated structure elastically opens to allow the connecting part 122 to pass through; when the connecting part 122 passes over the pleated structure, the pleated structure springs back, thus engaging the engaging position 132 with the connecting part 122.

[0079] The easy-to-install wheel 100 also includes a wheel cover 140, which covers the receiving cavity 111 of the wheel 110 to cover the engaging member 130. The inner side of the wheel cover 140 is provided with a positioning rib 141 for positioning the engaging member 130.

[0080] Please see Figures 4 to 7 When it is necessary to install and lock the wheel 110, simply position the engaging member 130 so that its length direction is aligned with the extension direction of the central axis of the rotating shaft 120, and then fit the wheel 110 onto the rotating shaft 120, with the rotating shaft 120 passing through the mounting hole 112. Next, position the engaging member 130 so that its length direction is perpendicular to the extension direction of the central axis of the rotating shaft 120, and simultaneously slide the engaging member 130 until the engaging position 132 engages with the connecting part 122. At this point, the engaging member 130 will be locked onto the side of the wheel 110, and the rotating shaft 120 will be unable to exit the mounting hole 112 due to the locking of the engaging member 130, thus connecting and locking the rotating shaft 120 to the wheel 110.

[0081] When it is necessary to unlock and remove the wheel 110, simply force the engaging member 130 to move, so that the engaging position 132 is away from the connecting part 122. Then swing the engaging member 130 so that the length direction of the engaging member 130 is in the same direction as the extension direction of the central axis of the rotating shaft 120. At this time, the rotating shaft 120 and the engaging member 130 can pass through the mounting hole 112, and the wheel 110 can be disengaged from the rotating shaft 120.

[0082] Compared with the prior art, the present invention, by setting a locking member 130, allows the locking member 130 to be movably fastened to the connecting part 122 of the rotating shaft 120. When the wheel 110 is connected to the rotating shaft 120, the locking member 130 can be swung so that its length direction is in the same direction as the extension direction of the central axis of the rotating shaft 120, or swung so that its length direction intersects the extension direction of the central axis of the rotating shaft 120. Therefore, when both are in the same direction, the locking member 130 and the rotating shaft 120 can pass through the mounting hole 112 of the wheel 110, achieving the purpose of removing the wheel 110; when they intersect, the locking member 130 is locked on the mounting hole 112, thereby preventing the wheel 110 from detaching from the rotating shaft 120, achieving the purpose of connecting and locking the wheel 110. Therefore, only the locking member 130 needs to be operated to quickly install and remove the wheel 110, which is simple in structure and very convenient to maintain and use.

[0083] like Figures 8 to 12 As shown in the figure, the structure of Embodiment 2 of the present invention is illustrated below:

[0084] Please see Figures 8 to 11 The easily detachable wheel 200 of this embodiment includes a wheel 210, a shaft 220, a locking member 230, and an elastic element 240. The wheel 210 has a receiving cavity 211 in its middle, with a mounting hole 212 at its center. One end of the shaft 220 has an annular locking groove 221, allowing the shaft 220 to extend into or retract from the mounting hole 212. The locking member 230 is radially movable and positioned on one side of the wheel 210. The elastic element 240 provides an elastic force that engages the locking member 230 in the locking groove 221, thereby locking the shaft 220 to the wheel 210. The elastic element 240 is a compression spring, with one end abutting against the locking member 230 and the other end abutting against the wheel 210. When the locking member 230 disengages from the locking groove 221, the shaft 220 and wheel 210 are released and separated.

[0085] For example Figure 11 As shown, specifically, the engaging member 230 has an elongated hole 231 through which the rotating shaft 220 passes. One end of the elongated hole 231 has a first engaging position 232, and the other end has a second engaging position 233. The curvatures of the first engaging position 232 and the second engaging position 233 are different. Specifically, the edge of the first engaging position 232 is arc-shaped, and the diameter of the arc-shaped side of the first engaging position 232 is smaller than the diameter of the rotating shaft 220. The edge of the elongated hole 231 between the first engaging position 232 and the second engaging position 233 is straight. This allows the rotating shaft 220 to engage with the edge of the first engaging position 232 when it is located at the first engaging position 232, and to directly pass through the second engaging position 233 and disengage from the engaging member 230 when it is located at the second engaging position 233, thus achieving the purpose of locking or unlocking.

[0086] For example Figure 11 and Figure 12 As shown, a pushing part 234 extends from one side of the engaging member 230. The pushing part 234 has a mating inclined surface 235. The easily detachable wheel 200 also includes a wheel cover 250. The wheel cover 250 is slidably disposed in the middle of the wheel 210 along the central axis of the rotating shaft 220. The wheel cover 250 has a driving part 251, and the driving part 251 has a driving inclined surface 252. The driving inclined surface 252 slides against the mating inclined surface 235. Pressing the wheel cover 250 along the axial direction of the rotating shaft 220 can cause the driving part 251 to drive the pushing part 234, thereby driving the engaging member 230 to slide. The wheel cover 250 can be used to cover the engaging member 230, making the wheel 210 more aesthetically pleasing, and can also serve as an operating component for operating the engaging member 230, thereby improving the convenience of operation. By utilizing the driving ramp 252 and the mating ramp 235, the wheel cover 250 can drive the locking piece 230 to move more smoothly, further improving the ease of operation.

[0087] Please see Figure 10 and Figure 11 When it is necessary to install and lock the wheel 210, simply press the button on the wheel cover 250, which will cause the wheel cover 250 to push the engaging member 230 to slide, so that the second engaging position 233 is aligned with the mounting hole 212. At this time, the rotating shaft 220 passes through the mounting hole 212 and the second engaging position 233, and the wheel 210 is fitted onto the rotating shaft 220. Afterward, release the engaging member 230, and the engaging member 230 will reset under the elastic force of the elastic element 240. At this time, the engaging member 230 will slide and the first engaging position 232 will be aligned with the mounting hole 212, with the edge of the first engaging position 232 engaged in the engaging groove 221. The rotating shaft 220 cannot exit the mounting hole 212 due to the locking of the engaging member 230, and the rotating shaft 220 can be connected and locked to the wheel 210.

[0088] Please see Figure 12 When it is necessary to unlock and remove the wheel 210, simply press the wheel cover 250 to drive the locking member 230. The locking member 230 can then slide and compress the elastic element 240, and the second locking position 233 will be aligned with the mounting hole 212 again. At this time, the shaft 220 will disengage from the second locking position 233 and the mounting hole 212, and the wheel 210 can then disengage from the shaft 220.

[0089] Compared with the prior art, the present invention, by setting a locking member 230, allows the locking member 230 to be movably mounted on the wheel 210. When the wheel 210 is connected to the axle 220, the locking member 230 can move to the locking groove 221 of the axle 220 and engage with it, thereby locking the wheel 210 and the axle 220. When the locking member 230 moves out of the locking groove 221, it releases the wheel 210 and the axle 220. Therefore, the wheel 210 can be quickly installed and removed simply by operating the locking member 230. The structure is simple, and maintenance and use are very convenient.

[0090] like Figures 13 to 19 As shown in the figure, the structure of Embodiment 3 of the present invention is illustrated below:

[0091] For example Figures 13 to 16 The easily detachable wheel 300 of this embodiment includes a wheel 310, a rotating shaft 320, a locking member 330, and an elastic element 340. The wheel 310 has a receiving cavity 311 in its middle, with a mounting hole 312 at its center. One end of the rotating shaft 320 has an annular locking groove 321, allowing the shaft to extend into or retract from the mounting hole 312. The locking member 330 is located on one side of the wheel 310, with one end pivotally connected to the side of the wheel 310 via a pin 350, and the other end having a locking position 331, which is recessed. After rotating along the pin 350, the locking member 330 can engage with or disengage from the locking groove 321. The elastic element 340 provides an elastic force that engages the locking member 330 in the locking groove 321, thereby locking the rotating shaft 320 to the wheel 310. The elastic element 340 is a compression spring, with one end abutting against the engaging member 330 and the other end abutting against the wheel 310. When the engaging member 330 disengages from the engaging groove 321, the rotating shaft 320 and the wheel 310 can be released and separated.

[0092] For example Figure 16 As shown, a pushing part 332 extends from one side of the engaging member 330. The pushing part 332 has a mating inclined surface 333. The easily detachable wheel 300 also includes a wheel cover 360. The wheel cover 360 is slidably disposed in the middle of the wheel 310 along the central axis of the rotating shaft 320, and the wheel cover 360 has a driving part 361. The driving part 361 has a driving inclined surface 362, which slides against the mating inclined surface 333. Pressing the wheel cover 360 along the axial direction of the rotating shaft 320 causes the driving part 361 to drive the pushing part 332, thereby causing the engaging member 330 to swing around the shaft pin 350. The wheel cover 360 can be used to cover the engaging member 330, making the wheel 310 more aesthetically pleasing, and can also serve as an operating component for operating the engaging member 330, thereby improving the convenience of operation. By utilizing the driving ramp 362 and the mating ramp 333, the wheel cover 360 can drive the engagement piece 330 to move more smoothly, further improving the ease of operation.

[0093] Combination Figure 17 As shown, when it is necessary to install and lock the wheel 310, simply press the button on the wheel cover 360, which will cause the wheel cover 360 to push the engaging member 330 to swing, so that the engaging position 331 disengages from the mounting hole 312. At this time, the rotating shaft 320 passes through the mounting hole 312, and the wheel 310 is fitted onto the rotating shaft 320. Then, release the engaging member 330, and the engaging member 330 will rotate and reset under the elastic force of the elastic element 340. At this time, the engaging position 331 is facing the mounting hole 312 and the edge of the engaging position 331 is engaged in the engaging groove 321. The rotating shaft 320 cannot exit the mounting hole 312 due to the locking of the engaging member 330, and the rotating shaft 320 can be connected and locked to the wheel 310.

[0094] Combination Figure 18 and Figure 19 As shown, when it is necessary to unlock and remove the wheel 310, simply press the wheel cover 360 to drive the engaging member 330. The engaging member 330 can then swing and compress the elastic element 340, causing the engaging position 331 to leave the mounting hole 312. At this time, the rotating shaft 320 can disengage from the engaging member 330 and the mounting hole 312, and the wheel 310 can then disengage from the rotating shaft 320.

[0095] like Figures 20 to 22 As shown in the figure, the structure of Embodiment 4 of the present invention is illustrated below:

[0096] Please see Figure 20 and Figure 21The easily detachable wheel 400 of this embodiment has a structure that is basically the same as that of Embodiment 2, both including a wheel 410, a rotating shaft 420, a locking member 430, and an elastic element 440. The wheel 410 has a mounting hole 411 at its center, and one end of the rotating shaft 420 has an annular locking groove 421, allowing the rotating shaft 420 to extend into or retract from the mounting hole 411. The locking member 430 is movably disposed on one side of the wheel 410 along its radial direction. The elastic element 440 is a compression spring. The difference lies in that the locking member 430 has an elongated hole 431 through which the rotating shaft 420 passes. One end of the elongated hole 431 has a first locking position 432, and the other end has a second locking position 433. The curvatures of the first locking position 432 and the second locking position 433 are different. Specifically, the edge of the first locking position 432 is arc-shaped, and the diameter of the arc-shaped edge of the first locking position 432 is smaller than the diameter of the rotating shaft 420. The edge of the second engaging position 433 is arc-shaped, and the diameter of the arc-shaped edge of the second engaging position 433 is larger than the diameter of the rotating shaft 420. The edge of the elongated hole 431 between the first engaging position 432 and the second engaging position 433 is arc-shaped. This allows the rotating shaft 420 to engage with the edge of the first engaging position 432 when it is in the first engaging position 432, and to pass directly through the second engaging position 433 and disengage from the engaging member 430 when it is in the second engaging position 433, thus achieving the purpose of locking or unlocking. A pushing part 434 extends from one side of the engaging member 430. A through hole 412 is provided on the side of the wheel hub of the wheel 410 opposite the pushing part 434. The pushing part 434 can be pushed from the outside through the through hole 412, thereby pushing the engaging member 430 to slide.

[0097] Combination Figure 21 As shown, when it is necessary to install and lock the wheel 410, simply push the pushing part 434 so that the second engaging position 433 is aligned with the mounting hole 411. At this time, the rotating shaft 420 passes through the mounting hole 411 and the second engaging position 433, and the wheel 410 is fitted onto the rotating shaft 420. Afterward, release the engaging member 430, and the engaging member 430 resets under the elastic force of the elastic element 440. At this time, the engaging member 430 slides and the first engaging position 432 is aligned with the mounting hole 411, with the edge of the first engaging position 432 engaged in the engaging groove 421. The rotating shaft 420 cannot exit the mounting hole 411 due to the locking of the engaging member 430, and the rotating shaft 420 can be connected and locked with the wheel 410.

[0098] Combination Figure 21 As shown, when it is necessary to unlock and remove the wheel 410, simply push the push part 434 so that the second engagement position 433 is aligned with the mounting hole 411. At this time, the shaft 420 can disengage from the second engagement position 433 and the mounting hole 411, and the wheel 410 can be disengaged from the shaft 420.

[0099] Compared with the prior art, the present invention, by setting a locking member 430, allows the locking member 430 to be movably mounted on the wheel 410. When the wheel 410 is connected to the axle 420, the locking member 430 can move to the locking groove 421 of the axle 420 and engage with it, thereby locking the wheel 410 and the axle 420. When the locking member 430 moves out of the locking groove 421, it releases the wheel 410 and the axle 420. Therefore, the wheel 410 can be quickly installed and removed simply by operating the locking member 430. The structure is simple, and maintenance and use are very convenient.

[0100] like Figures 23 to 27 As shown in the figure, the structure of Embodiment 5 of the present invention is illustrated below:

[0101] Please see Figures 23 to 26 The easily detachable wheel 500 of this embodiment includes a wheel 510, a shaft 520, and a locking member 530. The wheel 510 has a receiving cavity 511 in its middle, and a mounting hole 512 at the center of the receiving cavity 511. One end of the shaft 520 has an annular locking groove 521, and the shaft 520 can extend into or retract from the mounting hole 512. The locking member 530 is disposed within the receiving cavity 511 and has an elastic portion 531. Specifically, the locking member 530 includes a U-shaped structure, with elastic portions 531 formed at both ends of the U-shaped structure. The elastic portions 531 elastically engage with the locking groove 521, allowing the shaft 520 to be connected and locked to the wheel 510.

[0102] Please see again Figure 26 and Figure 27 The end of the elastic part 531 extends into a guide part 532. The easily detachable wheel 500 also includes an operating member 540, which is slidably disposed on one side of the wheel 510 along the radial direction of the wheel 510. The operating member 540 has an oblique hole 541, and the guide part 532 is slidably disposed within the oblique hole 541 to drive the elastic part 531 to open. By providing the guide part 532, the operating member 540 can more easily drive the elastic part 531 to move, thereby improving the convenience of operation.

[0103] The easy-to-install and remove wheel 500 also includes a wheel cover 550, which is disposed on the receiving cavity 511 and covers the operating member 540. The wheel cover 550 is provided to cover the engaging member 530, thereby making the wheel 510 more aesthetically pleasing.

[0104] When it is necessary to install and lock the wheel 510, simply press the operating member 540, causing it to slide and push the guide part 532. The guide part 532 slides along the direction of the inclined hole 541, thereby causing the elastic part 531 to open and leave the mounting hole 512. At this time, the shaft 520 can pass through the mounting hole 512, and the wheel 510 is fitted onto the shaft 520. Afterward, release the operating member 540, and the elastic part 531 returns to its original position under the action of elastic force, at which point the elastic part 531 is locked in the engaging groove 521. The shaft 520 cannot exit the mounting hole 512 due to the locking of the engaging member 530, and the shaft 520 is thus connected and locked to the wheel 510.

[0105] When it is necessary to unlock and remove the wheel 510, simply press the operating member 540, causing it to slide and push the guide portion 532. The guide portion 532 slides along the inclined hole 541, thereby causing the elastic portion 531 to open and move away from the mounting hole 512. At this time, the shaft 520 can disengage from the engaging member 530 and the mounting hole 512, and the wheel 510 can then be disengaged from the shaft 520.

[0106] Compared with the prior art, the present invention provides a locking member 530 with an elastic portion 531 at one end. Utilizing the resilient nature of the elastic portion 531, when in its natural state, it can spring back and engage with the locking groove 521 of the rotating shaft 520, thus locking the rotating shaft 520 and the wheel 510 together. When the elastic portion 531 is opened under force, it can disengage from the locking groove 521 of the rotating shaft 520, thereby releasing the rotating shaft 520 from the wheel 510, thus achieving the purpose of unlocking both the wheel 510 and the rotating shaft 520. Therefore, the wheel 510 can be quickly installed and removed simply by operating the elastic portion 531, resulting in a simple structure and convenient maintenance and use.

[0107] like Figures 28 to 31 As shown in the figure, the structure of Embodiment Six of the present invention is illustrated below:

[0108] Please see Figures 28 to 30 The easily detachable wheel 600 of this embodiment includes a wheel 610, a pivot 620, a locking member 630, and an elastic element 640. The center of the wheel 610 is fixedly connected to one end of the pivot 620. The other end of the pivot 620 is provided with a locking groove 621 and a mounting hole 611 for inserting into or retracting from the support leg 1000 of the frame. The locking member 630 is movably disposed on the support leg 1000. The elastic element 640 provides an elastic force that engages the locking member 630 in the locking groove 621, thereby locking the pivot 620 and the support leg 1000 together. The elastic element 640 is a compression spring, with one end pressing against the locking member 630 and the other end contacting the support leg 1000. When the locking member 630 disengages from the locking groove 621, the pivot 620 and the support leg 1000 are released and separated.

[0109] Please see again Figure 31 The engaging component 630 has an elongated hole 631 through which the rotating shaft 620 passes. One end of the elongated hole 631 has a first engaging position 632, and the other end has a second engaging position 633. The curvatures of the first engaging position 632 and the second engaging position 633 are different. Specifically, the diameter of the arc-shaped edge of the first engaging position 632 is smaller than the diameter of the rotating shaft 620, while the diameter of the arc-shaped edge of the second engaging position 633 is larger than the diameter of the rotating shaft 620. This allows the rotating shaft 620 to engage with the edge of the first engaging position 632 when it is located at the first engaging position 632, and to directly pass through the second engaging position 633 and disengage from the engaging component 630 when it is located at the second engaging position 633, thus achieving the purpose of locking or unlocking. One end of the locking component 630 is provided with a pushing part 634, and the bottom of the support leg 1000 is provided with a through hole 1100. The through hole 1100 is directly opposite to the pushing part 634, and the locking component 630 can be pushed to slide through the through hole 1100.

[0110] Combination Figure 30 As shown, when it is necessary to install and lock the wheel 610, simply push the pushing part 634, so that the second engaging position 633 is aligned with the mounting hole 611. At this time, the axle 620 passes through the mounting hole 611 and the second engaging position 633 of the support leg 1000. Then, release the engaging member 630, and the engaging member 630 resets under the elastic force of the elastic element 640. At this time, the engaging member 630 slides and the first engaging position 632 is aligned with the mounting hole 611, and the edge of the first engaging position 632 is engaged in the engaging groove 621. The axle 620 cannot exit the mounting hole 611 due to the locking of the engaging member 630, and the wheel 610 and the axle 620 can be connected and locked with the support leg 1000.

[0111] Combination Figure 30 As shown, when it is necessary to unlock and remove the wheel 610, simply push the push part 634 so that the second engagement position 633 is aligned with the mounting hole 611. At this time, the shaft 620 can disengage from the second engagement position 633 and the mounting hole 611, and the wheel 610 and the shaft 620 can be disengaged from the support leg 1000.

[0112] Compared with the prior art, the present invention connects the wheel 610 to the axle 620 by setting a locking member 630. The locking member 630 is movably disposed on the support leg 1000. When the axle 620 is connected to the support leg 1000, the locking member 630 can move to the locking groove 621 of the axle 620 and engage with the locking groove 621 to lock the wheel 610. When the locking member 630 moves out of the locking groove 621, the wheel 610 is released. Therefore, the wheel 610 can be quickly installed and removed by simply operating the locking member 630. The structure is simple and maintenance and use are very convenient.

[0113] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
