Description

Technical Field

[0001] The utility model relates to the technical field of wheelbarrow wheels, in particular to an easily detachable wheelbarrow wheel. Background Art

[0002] Handcarts are widely used in daily life. The wheels of handcarts are damaged at a high rate during use, and thus the wheels need to be disassembled and repaired. However, the disassembly of the wheels of the handcart is cumbersome, and there are also problems such as instability after the wheels are fixed.

[0003] In response to the defects in the prior art, there are many wheel locking structures in the art, such as a detachable drive shaft wheel with publication number CN214822348U, which includes a wheel body, a mounting frame and a fixing frame. The wheel body is a cylindrical structure and has a mounting groove on its outer wall. An inner cavity is formed inside the wheel body, and a plurality of protrusions are arranged in an array on the inner wall of the inner cavity. A plurality of spokes are installed directly below the protrusions. The spokes are connected to a mounting frame, and a bayonet is formed on the mounting frame. A positioning block is movably connected to the bayonet. A mounting plate is connected to the positioning block, and an end of the mounting plate away from the positioning block is connected to a transmission rod, a fixing bracket is provided on the outer wall of the transmission rod, and a plurality of convex plates are arranged in an array on the outer wall of the fixing bracket, and a fixing block is movably connected to the inner part of the convex plate, and the fixing block is movably matched with the positioning hole provided on the convex block. The detachable drive shaft type wheel has a simple and reasonable structural design and is convenient for operators to install and disassemble.

[0020] See also Figures 1 to 3 The utility model provides an easily detachable cart wheel, including a walking wheel 1 and a fixed shaft 2, the fixed shaft 2 and the center of the walking wheel 1 are slidingly connected, one end of the fixed shaft 2 is slidingly sleeved with an active motion block 3, the active motion block 3 is hollow, one end of the active motion block 3 is provided with a driven motion block 4, one end of the driven motion block 4 is slidingly connected to the inner side wall of the active motion block 3, the active motion block 3 is provided with a plurality of clips 32, the bottom of the driven motion block 4 is provided with a connecting shaft 5, both ends of the connecting shaft 5 are sleeved with slides 6, an elastic member 7 is provided between the slides 6, the outer side of the fixed shaft 2 is sleeved with a sleeve 8, and one side of the sleeve 8 is fixedly connected to the center of the walking wheel 1.

[0021] See also Figures 1 to 3 In a further embodiment, the bottom of the active motion block 3 is provided with a plurality of arc blocks, the top of the driven motion block 4 is provided with an arc groove 41 that cooperates with the arc block, and there is an avoidance space between the arc grooves 41. The outer wall of the active motion block 3 is provided with a plurality of card grooves, and the card grooves and the card strips 32 are slidingly arranged. When the bottom of the arc block and the top of the arc groove 41 cooperate, the two sides of the card strip 32 do not contact the arc groove 41. When the arc surface of the arc plate 31 and the arc surface of the arc groove 41 cooperate, the two sides of the card strip 32 and the arc groove 41 are in contact.

[0022] See also Figures 1 to 3 In a further embodiment, the two ends of the elastic member 7 are respectively connected to the slide plate 6, and the slide plate 6 is divided into a moving part and a fixed part. The moving part is fixedly connected to the connecting shaft 5 but is slidably connected to the sleeve 8, and the fixed part is slidably connected to the connecting shaft 5 but is fixedly connected to the sleeve 8. When the fixed shaft 2 is pressed, the fixed shaft 2 drives the active motion block 3 to move. When the arc surface of the arc plate 31 on the active motion block 3 matches the arc surface of the arc groove 41, the two sides of the clip 32 are in contact with the arc groove 41, and the moving part compresses the elastic member 7. The moving part also drives the connecting shaft 5 to slide along the fixed part, and then pushes out the connecting shaft 5, so that the connecting shaft 5 is connected to the rotating shaft on the cart (not shown in the figure). When the fixed shaft 2 is pressed again, when the bottom of the arc block matches the top of the arc groove 41, the two sides of the clip 32 are not in contact with the arc groove 41, and the elastic member 7 drives the moving part to reset under the action of the fixed part, thereby retracting the connecting shaft 5 to complete the disassembly.

[0023] See also Figures 1 to 3 In a further embodiment, an empty slot 21 is provided at the end of the fixed shaft 2 away from the active motion block 3, and a connecting plate 11 is provided at the center of the walking wheel 1. An auxiliary plate 111 is slidably connected to the connecting plate 11. When fixing the wheel, in order to prevent accidental touching of the fixed shaft 2, the auxiliary plate 111 is set through the empty slot 21 to fix the fixed shaft 2. When removing the wheel, the auxiliary plate 111 is pulled out, and then the fixed shaft 2 is pressed to complete the disassembly.

[0024] See also Figures 1 to 3 In a further embodiment, a rough surface is provided on the end of the connecting shaft 5 away from the walking wheel 1. The setting of the rough surface of the connecting shaft 5 can increase the friction between the connecting shaft 5 and the rotating shaft, thereby facilitating the movement of the cart.

[0025] When the wheel is fixed, the fixed shaft 2 is pressed, and the fixed shaft 2 drives the active motion block 3 to move. When the arc surface of the arc plate 31 on the active motion block 3 matches the arc surface of the arc groove 41, the two sides of the clip 32 are in contact with the arc groove 41, and the moving part compresses the elastic member 7. The moving part also drives the connecting shaft 5 to slide along the fixed part, and then pushes out the connecting shaft 5, so that the connecting shaft 5 and the rotating shaft on the cart (not shown) are connected. When the wheel is fixed, in order to prevent the fixed shaft 2 from being accidentally touched, the auxiliary plate 111 is set through the empty groove 21 to fix the fixed shaft 2. When the fixed shaft 2 is pressed again, the bottom of the arc block and the top of the arc groove 41 are matched, and the two sides of the clip 32 are not in contact with the arc groove 41. The elastic member 7 drives the moving part to reset under the action of the fixed part, and then retracts the connecting shaft 5. When the wheel is removed, the auxiliary plate 111 is pulled out, and then the fixed shaft 2 is pressed to complete the disassembly.
