[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3 As shown, the utility model provides a stable structure of a construction cart, including a cart body 1, a fixed box 2 is fixedly connected to the bottom of the cart body 1, a transmission shaft 3 is movably connected to the inner cavity of the fixed box 2, the front end and back end of the transmission shaft 3 both pass through the inner side of the fixed box 2 and are fixedly connected to rollers 4, the front end and back end of the surface of the transmission shaft 3 are fixedly sleeved with flywheels 5, the top and bottom of the inner side of the flywheel 5 and the top and bottom of the transmission shaft 3 are slidably connected with sliding rods 6, the left side of the fixed box 2 is movably connected with a rotating rod 7 through a bearing seat, the right side of the rotating rod 7 passes through the interior of the fixed box 2 and is fixedly connected with a movable plate 8, the front end and back end of the right side of the movable plate 8 are slidably connected to the left side of the sliding rod 6 through sliding columns.

[0021] refer to Figure 3 An annular groove 9 is provided on the surface of the flywheel 5 and corresponds to the position of the slide bar 6. A clamping groove 10 is provided at the top and bottom of the annular groove 9. The number of the clamping grooves 10 is several and evenly distributed.

[0022] As a technical optimization solution of the utility model, the annular groove 9 and the clamping groove 10 are provided to assist the slide bar 6 in working and play a role of limiting, thereby avoiding the slide bar 6 from being separated during movement.

[0023] refer to Figure 2 A sliding groove 11 is provided on the surface of the sliding rod 6 and at a position corresponding to the sliding column, and the length of the sliding groove 11 is greater than the moving distance of the sliding column.

[0024] As a technical optimization solution of the present invention, the slide groove 11 is provided to enable the movable plate 8 to move inside the slide groove 11 and to play a limiting role, thereby preventing the movable plate 8 from being separated during the rotation process.

[0025] refer to Figure 2 The front end and the back end of the surface of the slide rod 6 are fixedly sleeved with a fixing ring 12, and the top of the fixing ring 12 is fixedly connected with an anti-collision pad 13, and the anti-collision pad 13 is used in conjunction with the fixing ring 12.

[0026] As a technical optimization solution of the utility model, the setting of the fixing ring 12 and the anti-collision pad 13 can assist the slide bar 6 in working, thereby avoiding the phenomenon of collision caused by the slide bar 6 moving beyond the distance.

[0027] refer to Figure 1 The front end and the back end of the left side of the bucket 1 are fixedly connected with a handle 14, and the surface of the handle 14 is provided with anti-skid patterns, and the handle 14 is used in conjunction with the anti-skid patterns.

[0028] As a technical optimization solution of the present invention, the handle 14 is provided to assist the bucket 1 in working, thereby preventing the bucket 1 from being unable to control the direction for operation and movement.

[0029] refer to Figure 2 The front end and the back end of the fixed box 2 are both provided with through holes 15 , and the diameter of the through hole 15 is larger than the diameter of the transmission shaft 3 .

[0030] As a technical optimization solution of the utility model, the provision of the through hole 15 enables the transmission shaft 3 to completely pass through the through hole 15 for mechanical transmission, thereby avoiding the phenomenon that the transmission shaft 3 is stuck in the through hole 15 due to the through hole 15 being too narrow.

[0031] The working principle and use process of the utility model are as follows: when in use, the handle 14 is held to push the bucket 1 to move as a whole, and the bucket 1 cooperates with the roller 4 and the transmission shaft 3 to rotate to drive the bucket 1 to move. When it is necessary to stop steadily, the rotating rod 7 is rotated, and the rotating rod 7 drives the movable plate 8 to rotate. The movable plate 8 rotates and cooperates with the sliding column and the sliding groove 11 to force the sliding rod 6 to separate up and down. The sliding rod 6 moves upward through the annular groove 9 to the inside of the locking groove 10 to lock the flywheel 5 and prevent it from rotating. The inability of the flywheel 5 to rotate prevents the transmission shaft 3 and the roller 4 from rotating. The inability of the roller 4 to rotate drives the bucket 1 as a whole to be unable to move, thereby achieving the effect of stable parking.

[0032] In summary: the stable structure of the construction cart, through the coordinated use of the cart body 1, the fixed box 2, the transmission shaft 3, the roller 4, the flywheel 5, the slide bar 6, the rotating rod 7 and the movable plate 8, solves the problem that most of the existing carts are man-powered carts that cannot stop steadily when passing through steep slopes and are prone to slipping.
