DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1-Figure 7 ,in, Figure 1 A schematic diagram of the overall structure of a baby carriage that is easy to fix provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of shown; Figure 3 for Figure 2 The schematic diagram of the split structure of the fixed component shown; Figure 4 for Figure 2 A schematic diagram of a partial structure of a fixing plate shown; Figure 5 for Figure 4 A schematic cross-sectional structure diagram of the fixing plate shown; Figure 6 for Figure 2 A schematic diagram of the internal structure of the fixing plate shown; Figure 7 for Figure 6 The schematic diagram of the disassembled structure of the limiting mechanism is shown.

[0025] In the specific implementation process, Figure 1-Figure 7 As shown, a baby stroller that is easy to fix includes a bed 1 for a baby to rest, a fixing frame 2 for fixing the bed 1, a plurality of universal wheels 3 with brakes, and a plurality of fixing components. The bottom of the bed 1 is fixedly connected to the top of the fixing frame 2, and the plurality of universal wheels 3 are respectively connected to the bottom of the fixing frame 2 through a plurality of fixing components.

[0026] The fixing assembly includes a sliding block 4 and a fixing plate 5. The fixing plate 5 is located at one side of the bottom of the fixing frame 2. The bottom of the sliding block 4 is fixedly connected to the top of the universal wheel 3. A convex groove matching the fixing plate 5 is provided on the top of the sliding block 4. The fixing plate 5 is located in the convex groove. The sliding block 4 can slide on the surface of the fixing plate 5. A limiting mechanism for limiting the sliding block 4 is provided in the fixing plate 5. By making the inside of the convex groove provided in the sliding block 4 fit with the surface of the fixing plate 5, the sliding block 4 can be prevented from shaking. The sliding block 4 can be limited by the limiting mechanism to prevent the sliding block 4 from sliding, thereby fixing and installing the universal wheel 3 at the bottom of the sliding block 4.

[0027] The limiting mechanism includes a first clamping block 6, a second clamping block 7 and a driving member, a clamping groove 8 is respectively provided on both sides of the inner wall of the convex groove, a groove is provided in the fixing plate 5, the first clamping block 6 and the second clamping block 7 are both located in the groove, and a first L-shaped block 9 and a second L-shaped block 10 are respectively provided on the opposite sides of the first clamping block 6 and the second clamping block 7, a first spring 11 is provided on the side of the first L-shaped block 9 away from the first clamping block 6, and one end of the first spring 11 away from the first L-shaped block 9 is fixedly connected to one side of the second clamping block 7, a second spring 12 is provided on the side of the second L-shaped block 10 away from the second clamping block 7, and one end of the second spring 12 away from the second L-shaped block 10 is fixedly connected to the first spring 11, and one end of the second spring 12 away from the second L-shaped block 10 is fixedly connected to the second spring 11. One side of a clamping block 6 is fixedly connected, and through grooves are respectively provided on both sides of the inner wall of the groove. The first clamping block 6 and the second clamping block 7 are respectively penetrated through the two through grooves on the side away from the first L-shaped block 9 and the second L-shaped block 10 and are respectively located in the two clamping grooves 8. The driving member is used to drive the first L-shaped block 9 and the second L-shaped block 10. The first L-shaped block 9 and the second L-shaped block 10 are respectively driven by the driving member to shrink the first clamping block 6 and the second clamping block 7 into the groove and compress the first spring 11 and the second spring 12 respectively. The first clamping block 6 and the second clamping block 7 shrink into the groove and separate from the two clamping grooves 8 respectively, so that the sliding block 4 loses its limit position.

[0028] The driving member includes a pressing block 13 and an extruding block 14. The extruding block 14 is located in the groove. Both sides of the bottom of the extruding block 14 are inclined. The first L-shaped block 9 and the second L-shaped block 10 are respectively provided with an inclined groove 15 on one side of the top. Both sides of the extruding block 14 are respectively fitted with one side of the inner wall of the two inclined grooves 15. The bottom of the pressing block 13 is fixedly connected to the extruding top. The top of the pressing block 13 passes through the top of the inner wall of the groove. By pressing the top of the pressing block, the pressing block pushes the extruding block 14 to move. The extruding block 14 squeezes the inner walls of the inclined grooves 15 provided on the tops of the first L-shaped block 9 and the second L-shaped block 10 through the inclined surfaces on both sides, so that the first L-shaped block 9 and the second L-shaped block 10 move.

[0029] The first clamping block 6 is provided with a first limiting groove 16 at the top and bottom, respectively, and the first limiting block 17 is provided at the top and bottom of the inner wall of the through slot where the first clamping block 6 is located, respectively. The first limiting block 17 can slide in the first limiting groove 16, and is used to limit the first clamping block 6 to prevent the first clamping block 6 from being separated from the through slot where it is located;

[0030] The second clamping block 7 is provided with a second limiting groove 18 at the top and bottom, respectively. The second clamping block 7 is provided with a second limiting block 19 at the top and bottom of the inner wall of the through slot where the second clamping block 7 is located. The second limiting block 19 can slide in the second limiting groove 18 to limit the second clamping block 7 to prevent the second clamping block 7 from being separated from the through slot where the second clamping block 7 is located.

[0031] Rollers 20 are respectively provided on both sides of the fixing frame 2. One side of the two rollers 20 is rotatably connected to the two sides of the fixing frame 2 respectively, so as to keep the balance of the fixing frame 2 and thus keep the sleeping bed 1 balanced.

[0032] The working principle of the utility model is as follows: when the universal wheel 3 needs to be disassembled, the pressing block is pressed on the top to make the pressing block push the extrusion block 14 to move, and the extrusion block 14 squeezes the inner wall of the inclined groove 15 set on the top of the first L-shaped block 9 and the second L-shaped block 10 through the inclined surfaces on both sides, so that the first L-shaped block 9 and the second L-shaped block 10 respectively drive the first clamping block 6 and the second clamping block 7 to shrink into the groove and compress the first spring 11 and the second spring 12 respectively, and the first clamping block 6 and the second clamping block 7 are moved into the groove. The contraction will disengage from the two slots 8 respectively, so that the sliding block 4 loses its limit, so that the sliding block 4 can slide down from the surface of the fixed plate 5. When installing the universal wheel 3, the pressing block is pressed to slide the sliding block 4 to the surface of the fixed plate 5, so that the two slots 8 are aligned with the first block 6 and the second block 7 respectively. By releasing the pressing block, the first spring 11 and the second spring 12 rebound and make the first block 6 and the second block 7 respectively snap into the two slots 8, so as to limit the sliding block 4 and fix the universal wheel 3.
