DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] The biggest advantage of the children's interactive amusement turntable is that it allows children to participate in interactive games, and children's favorite riding games are horse riding, bicycle riding and other riding games. Therefore, in addition to the turntable 1, baffle 2 and other necessary components of a general children's amusement turntable, the design focuses on the connection relationship between the transmission device 4 and the rideable wooden horse 7, the bicycle 6 and the bracket 5 and the fixed plate 20.

[0027] The transmission device 4 is arranged at the center bottom of the turntable 1, and the transmission device 4 includes a fixed part and a rotating part.

[0028] The fixed part of the transmission device 4 includes a column 18, a cross bar 19, a fixed plate 20 and an outer cylinder 14. The outer cylinder 14 is a metal cylinder with a closed lower end, which is the outer shell of the transmission device 4 and is responsible for installing and supporting all components of the transmission device 4. The thrust ring 10 is placed at the center of the bottom of the outer cylinder 14, that is, the position of the annular thrust ring 10 at the bottom of the outer cylinder 14 is movable. The lower end of the outer cylinder 14 is fixedly connected to the column 18, and the bottom of the column 18 is welded with a cross bar 19. The fixed plate 20 is welded on the outer edge of the upper port of the outer cylinder 14. The fixed plate 20 must be kept parallel to the turntable 1, and can be made of metal or other materials that are not easily deformed by force, or it can be prevented from deforming with the help of a flat foundation ground. The diameter of the fixed plate 20 is smaller than the diameter of the turntable 1 to meet the contact drive of the wheel rim 9.

[0029] The rotating part of the transmission device 4 includes a washer 11, a sleeve 12, a half shaft 13, a shaft end sleeve 15, a radial ball bearing 16 and a thrust ball bearing 17, wherein the half shaft 13 is a stepped shaft made of metal, and the half shaft 13 is installed in the outer cylinder 14 through a bearing. There are three shaft diameters on the half shaft 13, and a pair of radial ball bearings 16 are installed on the middle shaft diameter. The two radial ball bearings 16 are separated by the sleeve 12. The thrust ball bearing 17 is installed after the lower end shaft diameter of the half shaft 13 passes through the washer 11. After the half shaft 13 is installed in the outer cylinder 14, the lower end is inserted into the inner hole of the thrust ring 10, and the lower shaft end surface thereof is spaced from the inner bottom of the outer cylinder 14. The radial direction of the half shaft 13 is only positioned by two radial ball bearings 16.

[0030] An end sleeve 15 is installed on the upper end diameter of the half shaft 13. The cylindrical tube of the end sleeve 15 is sleeved on the upper end diameter of the half shaft 13. After the upper end of the end sleeve 15 passes through the center hole of the turntable 1, the bottom outer edge of the end sleeve 15 lifts the turntable 1 upward. The pressure on the half shaft 13 acts on the thrust ball bearing 17 through the lowest shoulder of the half shaft 13. The thrust ball bearing 17 applies force to the outer cylinder 14 and the column 18 through the thrust ring 10, thereby axially positioning the half shaft 13 and keeping the half shaft 13 and the turntable 1 rotating freely in the outer cylinder 14.

[0031] The interior of the bracket 5 is a hollow structure, that is, the bracket 5 can be made of a metal plate and is open along the length direction of the bracket 5. The rim 9 of the bicycle 6 passes through the middle of the opening of the bracket 5. The drive shaft 22 of the bicycle 6 is horizontally mounted on both side surfaces of the bracket 5. The bottom of the rim 9 passes through the long hole 23 on the turntable 1 and contacts the upper surface of the fixed plate 20. The pedal 21 is installed on the drive shaft. By rotating the pedal 21, the rim 19 rotates and can drive the turntable 1 to rotate; similarly, the wooden horse 7 is also installed on the bracket 5. The wooden horse has a rim 9 inside, and the rim 9 is also driven by the drive shaft 22 inside the bracket 5 to drive the turntable 1 to rotate.

[0032] In order to ensure the normal and long-term operation of the children's ride-on amusement turntable, it is very important to ensure that the turntable 1 is parallel to the fixed plate 20, and the distance between the two is maintained within a certain range. Therefore, it is necessary to adjust the distance between the turntable 1 and the fixed plate 20. A threaded hole is provided at the center of the upper end of the shaft end sleeve 15, and an adjusting bolt 3 is screwed into the threaded hole. The lower end of the adjusting bolt 3 is against the upper shaft end surface of the half shaft 13. The turntable 1 can be lifted or lowered by rotating the adjusting bolt 3, and the distance between the turntable 1 and the fixed plate 20 can be changed. It can be adjusted at any time during installation and use. At the same time, the tire of the rim 9 should be made of a material with high elasticity and a large friction coefficient. First, it can allow some small changes in the distance between the turntable 1 and the fixed plate 20, and the tire of the rim 9 can still keep in contact with the fixed plate 20. Second, the tire friction coefficient is large, and the rim 9 drives the fixed plate 20 without slipping. The cylindrical sleeve of the shaft end sleeve 15 is sleeved on the half shaft 13 and connected with each other by clearance fit, which can ensure that when the turntable 1 moves up and down, the upper end shaft diameter of the half shaft 13 guides the turntable 1 through the shaft end sleeve 15.

[0033] Since all the pressure on the half shaft 13 is transmitted to the thrust ball bearing 17 through the washer 11, if the washer 11 is deformed, it will directly affect the normal operation of the thrust ball bearing 17, so the height of the washer 11 is preferably 8-10 mm.

[0034] When installing the children's interactive amusement turntable, the uprights 19 and the outer cylinder 14 can be buried underground, and the crossbar 19 can make the device as a whole more stable.

[0035] Usage process

[0036] When a child sits on the amusement turntable and rides a wooden horse 7 or a bicycle 6, after stepping on the pedal 21, the torque drives the wheel rim 9 to rotate through the driving shaft 22. The wheel rim 9 passes through the long hole 23 on the turntable 1 and contacts the fixed plate 20. Since the fixed plate 20, the outer cylinder 14 and the column 18 are all fixed parts, when the wheel rim 9 rotates forward, the driving shaft 22 drives the bracket 5 to move forward. The bracket 5 is fixed on the turntable 1, and a rotation torque is applied to the turntable 1. Under the action of this torque, the turntable 1 rotates on the fixed plate 20 with the half shaft 13 as the center. Since the half shaft 13 and the outer cylinder 14 are connected by a bearing, the amusement turntable can be driven to rotate without applying a lot of force to the pedal. Children see that they can ride a bicycle 6 or a wooden horse 7 to rotate with the amusement turntable, and can also control the speed, which can be fast or slow. They feel mysterious and get great satisfaction through operation. It greatly stimulates children's interest in play and exercises their bodies, while also planting seeds of mystery in children's hearts, leaving an impression on their later growth and exploration of knowledge.

[0037] It should be noted that the amusement turntable still needs to be operated by children under the supervision of adults. If conditions permit, it can be used as a children's amusement device in a family courtyard, or as an amusement project for families in an amusement park for children to play. If several children ride at the same time, the amusement turntable can rotate faster, which can cultivate children's sense of collective cooperation.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
