[0028] In view of the problems existing in the prior art, the utility model provides a universal wheel fixing frame for producing a trolley case, comprising a U-shaped bracket 11, wherein the inner wall of the U-shaped bracket 11 is symmetrically provided with L-shaped grooves 12, and a square groove 13 is provided between the two L-shaped grooves 12;

[0029] A quick fixing mechanism is slidably installed inside each of the two L-shaped grooves 12;

[0030] The quick fixing mechanism includes a first card block 14 and a second card block 15. The square groove 13 is symmetrically provided with a first slide groove 16 and a second slide groove 17. The two first slide grooves 16 are both located above the second slide groove 17. The first card block 14 and the second card block 15 are L-shaped. The quick fixing mechanism also includes a first slider 18, a first square plate 19, a first rack group 21, a support block 22, a second slider 23, a second square plate 24, a second rack group 25, a rotating rod 26 and a gear 27. The two first sliders 18 are both located inside the first slide groove 16 for sliding installation. The first square plate 19 is located between the first sliders 18 and fixedly installed. The first rack group 21 is located at the lower end of the first square plate 19 and fixedly installed. The two support blocks 22 are slidably installed inside the second slide groove 17. By rotating the rotating rod 26 clockwise, the rotating rod 26 drives the gear 27 to rotate and engage with the first rack group 21 and the second rack group 25 respectively, so that the second rack group 25 will drive the second square plate 24 and the second card block 15 to move toward the side of the first card block 14, and the first rack group 21 drives the first square plate 19 to move toward the side of the second card block 15, thereby realizing the two-way approach of the first card block 14 and the second card block 15, so that the first card block 14 and the second card block 15 are quickly inserted into the card slot inside the trolley case, thereby completing the installation, which is simple, fast and convenient to use, thereby improving the installation efficiency.

[0031] The first rack group 21 is fixedly installed between the support blocks 22, the two second sliders 23 are both slidably installed inside the second slide groove 17, the second square plate 24 is fixedly installed between the second sliders 23, the first square plate 19 and the second square plate 24 are fixedly installed with the first clamping block 14 and the second clamping block 15 respectively, the second rack group 25 is fixedly installed at the upper end of the second square plate 24, the rotating rod 26 is rotatably installed inside the square groove 13, the gear 27 is fixedly installed on the circumferential surface of the rotating rod 26, the gear 27 is meshed and installed between the first rack group 21 and the second rack group 25, and the rotating rod 26 is partially exposed outside the U-shaped bracket 11 On the side, a universal wheel body 28 is symmetrically fixedly installed at the lower end of the U-shaped bracket 11.

[0032] Working principle:

[0033] The first step is to install the suitcase (two card slots are provided inside the suitcase, and the connection between the card slots and the first card block 14 and the second card block 15 is card connection) between the two L-shaped slots 12, and then the rotating rod 26 can be rotated clockwise, so that the rotating rod 26 drives the gear 27 to rotate and mesh with the first rack set 21 and the second rack set 25 respectively. At this time, the second rack set 25 will drive the second square plate 24 and the second card block 15 to move toward the first card block 14, and the second card block 15 and the second slide block 23 will slide in the L-shaped slot 12 and the second slide slot 17 respectively. At this time, the first rack set 21 located above the second rack set 25 will mesh with the gear 27, so that the first rack set 21 drives the first square plate 19 to move toward the second card block 15.

[0034] In the second step, when the first square plate 19 moves, it will drive the first clamping block 14, the first slider 18 and the support block 22 to slide in the L-shaped groove 12, the first slide groove 16 and the second slide groove 17 respectively, so as to realize the two-way approach of the first clamping block 14 and the second clamping block 15, and then the first clamping block 14 and the second clamping block 15 are clamped into the inside of the trolley case to complete the fixation, thereby completing the fixation of the universal wheel body 28 on the trolley case.
