[0012] Compared with the prior art, the beneficial effects of the utility model are: 1. The ground roller frame, by sliding the fixed shaft in the middle of the supporting wheel into the two bracket grooves, the two limit blocks are stuck in the limit grooves. In the process of the limit block moving downward, the block can be squeezed to make the two blocks move away from each other. When the limit block is completely stuck in the limit groove and no longer moves, the sliding frame is driven by the tension of the spring to approach the side plate, so that the sliding frame drives the block to be stuck in the slot, thereby achieving the purpose of locking the limit block and preventing the fixed shaft from slipping out of the bracket groove, thereby achieving the purpose of installing the supporting wheel, abandoning the traditional use of lock nuts to fix the supporting wheel. Even if the supporting wheel vibrates, the block will not fall out of the slot, thereby improving the convenience of installation operation and the stability of the use of the ground roller frame.

[0013] 2. The ground roller frame can be removed from the ground roller frame by pulling the handle to drive the sliding frame away from the side plate, so that the sliding frame can drive the card block to leave the card slot, so that the limit block is in a free movable state in the limit slot, and the supporting wheel can be lifted up to remove it from the ground roller frame.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a ground roller frame, including a support base 1, baffles 2 are respectively provided on both sides of the support base 1, two side plates 3 are respectively fixed to the opposite surfaces of the two baffles 2, a support wheel 4 is connected between the two side plates 3, slideways 13 are respectively opened on both sides of the top of the support base 1, an adjustment component 14 is slidably connected in the slideway 13, and the adjustment component 14 is fixed to the baffle 2 and the two side plates 3.

[0023] The adjustment assembly 14 includes a slide 141. The slide 141 and the slide 13 are both T-shaped. A fastening bolt 142 is threadedly connected to the slide 141. Through the mutual cooperation between the slide 141 and the slide 13, the slide 13 plays a role of supporting and limiting the slide 141, ensuring that the slide 141 drives the side plate 3 and the baffle 2 to move stably and horizontally.

[0024] A plurality of positioning grooves 15 are provided at the bottom of the slide 13, and a fastening bolt 142 is clamped in one of the positioning grooves 15. Four mounting holes 16 are provided on both sides of the top of the support base 1. Because of the positioning grooves 15, the fastening bolt 142 can be clamped in any positioning groove 15, so as to fix the slide 141.

[0025] Two bracket grooves 5 are provided on the side plate 3, and a bearing 6 is clamped in the middle of the supporting wheel 4. Due to the bearing 6, the supporting wheel 4 can drive the outer ring of the bearing 6 to rotate when rotating, ensuring that the fixed shaft 7 does not rotate on the inner wall of the bearing 6, thereby improving the smoothness of the rotation of the supporting wheel 4. The fixed shaft 7 is sleeved in the bearing 6, and the fixed shaft 7 is embedded in the two opposite bracket grooves 5. Limiting blocks 8 are fixed on both sides of the fixed shaft 7.

[0026] A limiting groove 10 is provided at the bottom of the bracket groove 5, and the limiting block 8 is inserted into the limiting groove 10. A slot 9 is provided on one side of one of the limiting blocks 8, and two locking components 11 are provided on one side of the limiting groove 10. The locking component 11 is inserted into the slot 9. The locking component 11 includes a sliding frame 111. A block 112 is fixed to one side of the inner wall of the sliding frame 111. The block 112 is inserted into the slot 9. One side of the top of the block 112 is designed with an inclined surface, and the shape of the block 112 is adapted to the shape of the slot 9. Because one side of the block 112 is designed with an inclined surface, the block 112 can be squeezed when the limiting block 8 moves downward to change the position of the block 112. There is no need for manual assistance to adjust the position of the block 112 to insert the limiting block 8 into the limiting groove 10, thereby improving the convenience of operation.

[0027] A handle 114 is fixedly connected to the side of the sliding frame 111 away from the side plate 3, and a sliding groove 12 is provided on the side of the side plate 3 corresponding to the sliding frame 111. The end of the sliding frame 111 is slidably connected in the sliding groove 12. Because the handle 114 is provided, the position of the sliding frame 111 and the block 112 can be easily adjusted by pulling the handle 114. Secondly, the sliding groove 12 can limit the sliding frame 111, thereby improving the stability of the sliding frame 111 driving the block 112 to move.

[0028] Two springs 113 are fixedly connected between the sliding frame 111 and the side plate 3 .

[0029] The working principle of the utility model is as follows: when in use, the handle 114 is pulled to drive the sliding frame 111 away from the side plate 3, and the sliding frame 111 drives the card block 112 to fall off the card slot 9, and then the supporting wheel 4 is lifted up to remove it, and the fixed shaft 7 on the supporting wheel 4 is inserted into another bracket slot 5. When the limit block 8 is inserted into the limit slot 10, the card block 112 can be squeezed during the downward movement of the limit block 8, so that the two card blocks 112 are separated from each other, and when the limit block 8 is completely inserted into the limit slot 10 and no longer When moving, the sliding frame 111 is driven by the pulling force of the spring 113 to approach the side plate 3, so that the sliding frame 111 drives the card block 112 to be stuck in the card slot 9, thereby achieving the purpose of locking the limit block 8. When adjusting the position of the baffle 2 and the two side plates 3, loosen the fastening bolts 142 to make it disengage from the positioning groove 15, pull the baffle 2 to make it drive the sliding seat 141 to slide in the slide 13, and when positioning the sliding seat 141, tighten the fastening bolts 142 and stick it into other positioning grooves 15.
