Description

Technical Field

[0001] The utility model relates to the technical field of baby walkers, and specifically relates to a speed reduction device for a baby walking cart. Background Art

[0002] As a kind of children's walking toy, baby walkers are widely loved by people. The speed of common baby walkers is relatively inconvenient to adjust, and the deceleration effect is not good. It is easy for children to fall because the vehicle speed is too fast and they can't keep up with the cart, so it is relatively inconvenient to use. Content of the Utility Model

[0003] In view of the problems existing in the prior art, the utility model discloses a speed reduction device for a baby walking cart, which includes a covering piece, a connecting piece, connecting screw holes, a cover plate, connecting screws, a knob, and a rubber pressing piece; the covering piece is a thin iron sheet, with a semi-circular groove formed by bending downward at the center of the bottom, bent upward on both left and right sides, and a connecting piece is welded and fixed on the top; three connecting screw holes are arranged along a straight line on the connecting piece; there are a countersunk hole on each of the front and rear sides of the upper surface of the cover plate, and a screw hole is opened in the center; the connecting screw is installed in the countersunk hole and fixed on the middle connecting screw hole; the knob is installed in the screw hole in the center of the cover plate, a screw rod is fixed at the center of its lower surface, and a rubber pressing piece is installed at the end of the screw rod.

[0004] As a preferred technical solution of the utility model, the edge of the connecting piece is flush with the edge of the cover plate.

[0005] The beneficial effects of the utility model: The speed of the cart can be easily changed by adjusting the knob, and by adjusting the pressure between the rubber pressing piece and the rotating shaft, the rotating speed of the cart rotating shaft can be changed, making the adjustment more simple and effective.

[0012] Embodiment 1

[0013] As Figures 1 to 4 shown, the utility model discloses a deceleration device for a baby walker, which includes a covering piece 1, a connecting piece 2, a connecting screw hole 3, a cover plate 4, a connecting screw 5, a knob 6, and a rubber pressing piece 7; the covering piece 1 is a thin iron sheet, with a semicircular groove formed by bending downward at the center of the bottom, bent upward on both left and right sides, and a connecting piece 2 is welded and fixed at the top; the connecting piece 2 is provided with three connecting screw holes 3 along a straight line.

[0014] On the upper surface of the cover plate 4, there is a countersunk hole on each of the front and rear sides, and a screw hole is opened in the center; the connecting screw 5 is installed in the countersunk hole and fixed on the middle connecting screw hole 3; the knob 6 is installed in the central screw hole of the cover plate 4, a screw rod is fixed at the center of its lower surface, and a rubber pressing piece 7 is installed at the end of the screw rod. On the lower surface of the baby walker 10, there are rectangular grooves on each of the front and rear sides, a rectangular hole is opened in the center of the rectangular groove, the connecting piece 2 is clamped into the rectangular groove, and screws are installed on the two side connecting screw holes 3 and fixed on the baby walker 10, the covering piece 1 passes through the rectangular hole, the center of the rotating shaft 8 is clamped into the semicircular groove of the covering piece 1, and wheels 9 are installed after both ends pass through the baby walker 10, the cover plate 4 is clamped into the rectangular groove and fixed on the connecting screw hole 3 in the center of the connecting piece 2 by installing the connecting screw 5, and the rubber pressing piece 7 abuts against the rotating shaft 8.

[0015] The working principle of the utility model: when the utility model is in use, only need to rotate the knob 6, so that the screw rod on the lower side of the knob 6 drives the rubber pressing piece 7 to press against the rotating shaft 8, and cooperate with the covering piece 1 to increase the friction force when the rotating shaft rotates. The friction force when the rotating shaft rotates can be controlled by submitting the number of turns of the rotation 6, so that it is at a suitable flying speed, the adjustment is simple and convenient, and the deceleration is more effective.

[0016] The components not detailed in this article are prior art.

[0017] Although the specific embodiments of the utility model are described in detail above, the utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the utility model, and the modifications or deformations without creative labor are still within the protection scope of the utility model.
