Embodiment 1

[0047] Such as Figures 1 to 4 As shown, a rotary locking wheel includes a wheel connecting part 1, a wheel frame 2 rotatably connected to the wheel connecting part 1, and a wheel 3 hinged between the two sides of the wheel frame 2; it is characterized in that: The rotary locking wheel also includes a locking mechanism 21 which is arranged on the wheel frame 2 and can lock the rotation of the wheel frame 2 and the wheel 3 relative to the wheel connection part 1. The locking mechanism 21 includes : positioning plate 211, which is fixedly connected to the bottom end of the wheel connecting portion 1, and the positioning plate 211 is provided with a positioning portion 2111; brake pads 212, whose two sides are hinged on both sides of the wheel frame 2, so The front end of the brake pad 212 is provided with a limiting portion 2121 that engages with the positioning portion 2111; a presser 213 is located above the brake pad 212, connected with the wheel frame 2 and can be opposite t...

Embodiment 2

[0057] Such as Figures 5 to 6 As shown, the difference between the second embodiment and the second embodiment is that the wheel connection part 1 has changed, and the wheel connection part 1 includes: a rotating connection top cover 14, which is arranged on the wheel frame 2 Moreover, the fifth ball groove 141 for accommodating the large ball 26 is provided on the rotating connection top cover 14 , and the third ball groove 2001 cooperates with the fifth ball groove 141 to form a groove corresponding to the size of the large ball 26 . The third cavity 15, the large ball 26 can roll in the third cavity 15, and each of the four corners of the rotary connection top cover 14 is provided with one for fixing the rotary locking wheel. Fixed through hole 142; rotating connecting shaft 16, which corresponds to the size of the circular through hole and the rotating connecting top cover 14 passes through the positioning plate 211, the main body of the wheel frame 2 and the rotating con...

Abstract

The invention discloses a rotary locking wheel. The rotary locking wheel comprises a wheel connection part 1, a wheel frame 2 rotatably connected with the wheel connection part 1, and a wheel 3 hingedbetween two sides of the wheel frame 2; and the rotary locking wheel also comprises a locking and pressing mechanism 21 arranged on the wheel frame 2 and can lock the wheel frame 2 and the wheel 3 tobe prevented from rotating relative to the wheel connection part 1, the locking and pressing mechanism 21 comprises a positioning disc 211, a brake plate 212 and a press-fitting device 213, the positioning disc is provided with a positioning part 2111; the brake plate 212 is hinged onto the wheel frame 2, and the brake plate 212 is provided with a limiting part 2121; and when the press-fitting device 213 is pressed downwards, the rear end of the brake plate 212 is driven to press against the wheel 3, the front end of the brake plate 212 is tilted upwards, so that the limiting part 2121 is engaged with the positioning part 2111, and the swinging problem of the wheel frame relative to the wheel connection part can be solved.

Description

【Technical field】 [0001] The present application relates to the field of locking wheels, in particular, to a rotary locking wheel. 【Background technique】 [0002] Locking wheels are usually used in various mechanical handling and cargo transportation, which is convenient for human propulsion. [0003] In addition, generally when valuables or heavy objects are transported, rollers with brake pads or brake pads are used to prevent the rollers from rolling. But these rollers equipped with brake pads are not very safe, because the wheel frame of the roller will swing on uneven roads, and the swing of the wheel frame may cause the goods to tip over. 【Content of invention】 [0004] The purpose of this application is to solve the above technical problems by providing a rotary locking wheel. [0005] In order to solve the above technical problems, the application is realized through the following technical solutions: [0006] A rotary locking wheel, comprising a wheel connectin...
