Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a wheel hub with a self-locking function. Background Art

[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile and is mounted on an axle. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material.

[0003] The wheel hub currently used in the cart is fixed to the body by using a nut. However, with the long-term use of the cart, the wheel hub is constantly vibrated, and the nut is easily loosened, resulting in the wheel hub being no longer tightly fixed. For this reason, we propose a wheel hub with a self-locking function. Utility Model Content

[0004] The purpose of the utility model is to provide a wheel hub with a self-locking function to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned object, the utility model provides the following technical solutions: a wheel hub with a self-locking function, comprising a wheel hub;

[0006] A groove formed in the center of the hub;

[0007] A locking portion disposed on the surface of the hub for locking the bolt;

[0008] A control part is arranged on the surface of the hub for controlling the locking part.

[0009] Preferably, the locking portion includes a rotating disk, which is rotatably mounted on the surface of the wheel hub, the surface of the rotating disk is provided with an arc groove, the surface of the wheel hub is provided with a sliding groove, a sliding rod is slidably mounted on the inner side of the sliding groove, the sliding rod passes through the arc groove, one end of the sliding rod away from the wheel hub is hingedly connected to a resistance rod, a torsion spring is fixed to the surface of the sliding rod, and one end of the torsion spring away from the sliding rod is fixed to the resistance rod. When the wheel hub is installed, the resistance rod can resist the surface of a nut that fixes the wheel hub. At this time, the nut rotates clockwise when it is rotated and tightened, and the nut resists on the resistance rod, so that the resistance rod swings at the position hinged with the sliding rod, and when the nut rotates counterclockwise, the resistance rod can resist the surface of the nut, locking it, thereby achieving a self-locking effect and preventing the nut from loosening due to vibration when the wheel hub is in use.

[0010] Preferably, the control part includes a rotating ring, which is rotatably installed on the inner side of the groove, a spiral spring is fixed on the surface of the rotating ring, one end of the spiral spring away from the rotating ring is fixed on the inner side of the groove, a control ring is slidably installed on the inner side of the rotating ring, and an annular groove and a vertical groove are opened on the inner side of the groove.

[0011] Preferably, the annular groove and the vertical groove are connected, a connecting block is fixed on the inner side of the control ring, and the end of the connecting block away from the control ring is inserted into the inner side of the annular groove, a large gear is fixed on the surface of the rotating ring, and a small gear is fixed on the surface of the turntable, and the large gear and the small gear are meshed with each other. When the control ring is rotated, the control ring can drive the rotating ring and the large gear to rotate together, so that the turntable can be driven to rotate by the small gear. When the control ring is pushed and the control ring slides to the position of the vertical groove with the connecting block, the control ring and the rotating ring can be limited, so that the rotating ring cannot rotate under the action of the spiral spring.

[0012] Preferably, a protective cover is clamped on the surface of the wheel hub, and the locking part and the control part can be controlled by removing the protective cover, and the nut fixing the wheel hub can be installed and removed. By installing the protective cover, the locking part and the control part can be protected.

[0013] Preferably, the arc groove, slide groove, slide rod, resistance rod and torsion spring are each provided with six groups, and the six groups of arc grooves, slide grooves, slide rods, resistance rods and torsion springs are all arranged in a circular array with the center point of the turntable as the center. The six groups of resistance rods can resist the edge of the nut, thereby achieving a better locking effect.

[0014] Compared with the prior art, the utility model provides a wheel hub with a self-locking function, which has the following beneficial effects:

[0015] 1. The wheel hub with self-locking function has a locking part, when the wheel hub vibrates during use, causing the nut to rotate counterclockwise, the abutment rod can abut against the surface of the nut to lock it, thereby achieving a self-locking effect and preventing the nut from loosening due to vibration when the wheel hub is in use.

[0016] 2. The wheel hub with self-locking function, through the control part and the locking part provided, when the nut needs to be disassembled, it is only necessary to remove the protective cover again and rotate the control ring, and the control ring drives the swivel to rotate together. When the control ring drives the connecting block to rotate to the position of the vertical groove, the control ring is pushed to move, and the connecting block slides into the vertical groove, and the swivel is limited so that it cannot rotate in the opposite direction under the action of the spiral spring. When the swivel rotates, the swivel drives the turntable to rotate through the large gear and the small gear. Since the slide rod is limited by the slide groove, the turntable contacts the slide rod through the arc groove on its surface, so that the slide rod moves along the slide groove to the side away from the center of the turntable, and the slide rod moves with the resistance rod, so that the resistance rod no longer resists the nut, so that the nut can be disassembled by rotating counterclockwise.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a wheel hub with a self-locking function, comprising a wheel hub 1, a groove 2 is opened in the center of the wheel hub 1, a locking portion 3 for locking a bolt is arranged on the surface of the wheel hub 1, a control portion 4 for controlling the locking portion 3 is arranged on the surface of the wheel hub 1, a protective cover 5 is clamped on the surface of the wheel hub 1, the locking portion 3 and the control portion 4 can be controlled by removing the protective cover 5, and the nut fixing the wheel hub 1 can be installed and removed, and the locking portion 3 and the control portion 4 can be protected by installing the protective cover 5.

[0024] The locking portion 3 includes a rotating disk 31, which is rotatably mounted on the surface of the wheel hub 1. The surface of the rotating disk 31 is provided with an arc groove 32, and the surface of the wheel hub 1 is provided with a sliding groove 33. A sliding rod 34 is slidably mounted on the inner side of the sliding groove 33. The sliding rod 34 passes through the arc groove 32, and an end of the sliding rod 34 away from the wheel hub 1 is hingedly connected to a resistance rod 35. A torsion spring 36 is fixed to the surface of the sliding rod 34, and an end of the torsion spring 36 away from the sliding rod 34 is fixed to the resistance rod 35. When the wheel hub 1 is installed, the resistance rod 35 can resist the surface of the nut that fixes the wheel hub 1. At this time, the nut rotates clockwise when it is rotated and tightened, and the nut resists on the resistance rod 35, so that the resistance rod 35 swings at the position hinged with the sliding rod 34. When the nut rotates counterclockwise, the resistance rod 35 can resist the surface of the nut, locking it, realizing the self-locking effect, and preventing the nut from loosening due to vibration when the wheel hub 1 is in use.

[0025] The control part 4 includes a rotating ring 41, which is rotatably mounted on the inner side of the groove 2. A spiral spring 42 is fixed on the surface of the rotating ring 41, and one end of the spiral spring 42 away from the rotating ring 41 is fixed on the inner side of the groove 2. A control ring 43 is slidably mounted on the inner side of the rotating ring 41. An annular groove 45 and a vertical groove 46 are provided on the inner side of the groove 2. The annular groove 45 and the vertical groove 46 are connected. A connecting block 47 is fixed on the inner side of the control ring 43. One end of the connecting block 47 away from the control ring 43 is plugged into the inner side of the annular groove 45. The rotating ring 41 A large gear 48 is fixed on the surface of the rotating disk 31, and a small gear 44 is fixed on the surface of the rotating disk 31. The large gear 48 and the small gear 44 are meshed with each other. When the control ring 43 is rotated, the control ring 43 can drive the rotating ring 41 and the large gear 48 to rotate together, so that the rotating disk 31 can be driven to rotate through the small gear 44. When the control ring 43 is pushed and the control ring 43 slides to the position of the vertical groove 46 with the connecting block 47, the control ring 43 and the rotating ring 41 can be limited, so that the rotating ring 41 cannot rotate under the action of the spiral spring 42.

[0026] There are six groups of arc grooves 32, slide grooves 33, slide rods 34, resistance rods 35 and torsion springs 36, and the six groups of arc grooves 32, slide grooves 33, slide rods 34, resistance rods 35 and torsion springs 36 are arranged in a circular array with the center point of the turntable 31 as the center. The six groups of resistance rods 35 can resist the edge of the nut, thereby achieving a better locking effect.

[0027] Based on the above implementation, the protective cover 5 is removed, the wheel hub 1 is aligned with the installation position, the bolts at the installation position pass through the through holes reserved on the wheel hub 1, the nuts for fastening the wheel hub 1 are screwed on accordingly, the installation of the wheel hub 1 is completed, and the protective cover 5 is buckled back on.

[0028] As the wheel hub 1 is used, the abutment rod 35 abuts against the surface of the wheel nut to lock the nut so that the nut cannot rotate counterclockwise, thereby preventing the nut from loosening due to vibration when the wheel hub 1 is in use.

[0029] When the nut needs to be removed, the protective cover 5 only needs to be removed again, and the control ring 43 is rotated. The control ring 43 drives the swivel ring 41 to rotate together. When the control ring 43 drives the connecting block 47 to rotate to the position of the vertical groove 46, the control ring 43 is pushed to move, and the connecting block 47 slides into the vertical groove 46 to limit the swivel ring 41 so that it cannot rotate in the opposite direction under the action of the spiral spring 42.

[0030] When the swivel ring 41 rotates, the swivel ring 41 drives the turntable 31 to rotate through the large gear 48 and the small gear 44. Since the slide rod 34 is limited by the slide groove 33, the turntable 31 contacts the slide rod 34 through the arc groove 32 opened on its own surface, so that the slide rod 34 moves along the slide groove 33 to the side away from the center of the turntable 31, and the slide rod 34 moves with the resistance rod 35, so that the resistance rod 35 no longer resists the nut, so that the nut can be disassembled by rotating counterclockwise. After disassembly, it is only necessary to pull the control ring 43 so that the control ring 43 and the connecting block 47 slide back into the annular groove 45. Under the action of the spiral spring 42, the swivel ring 41 rotates in the opposite direction, thereby controlling the slide rod 34 to reset the resistance rod 35.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
