[0001] The utility model relates to a seesaw, more particularly to a level-breaking children's seesaw. Background Art

[0002] With the progress of society, people have gradually paid more attention to the cultivation of children's various abilities. Therefore, a large number of children's amusement facilities have emerged for the purpose of exercising the body and cultivating children's body balance ability, such as children's climbing frames, children's trampolines, children's seesaws, etc.

[0003] Most of the existing children's seesaws are made of long wooden boards or long metal tubes. A support part is provided in the middle of the seesaw, and two seats are provided at both ends of the seesaw. Two children can sit on the two ends of the seesaw respectively, and the two children take turns to push the ground with their feet to make one end rise and the other end fall, and so on. However, the above method requires two children of similar weight to play. However, it is difficult to get children of similar weight together during the actual play process, so the play experience is not good.

[0004] Currently, there is patent No. 202122807849.8 in the prior art. A utility model patent for a level-breaking rocking seesaw discloses that by setting a transmission device and a motor and a main shaft, the motor drives the main shaft to rotate, and then the main shaft drives the seesaw to actively drive the seesaw up and down, thereby solving the problem in the prior art that the seesaw requires two children of similar weight to play. However, the structure of the level-breaking rocking seesaw with the above-mentioned structure is relatively complicated and has a high cost. Utility Model Content

[0007] As a further improvement of the utility model, the support column is hollow, an air pipe is vertically passed through the support column, a pipe is extended from the side of the air pipe, and the end of the pipe passes through the side wall of the support column to the outside to connect with an external pumping and inflation device.

[0008] As a further improvement of the utility model, a plurality of air holes are provided on the side wall of the trachea, so that air can be filled into the protective airbag through the air holes.

[0009] As a further improvement of the utility model, the damping device is composed of two air buffer rods, which are respectively arranged on the left and right sides of the support column, one end of the two air buffer rods is hinged on the lower side of the plate body, and the other end is hinged on the left and right sides of the support column, the two air buffer rods are connected to the inside of the support column through a pipe, and the protective airbag is made of elastic cloth.

[0010] As a further improvement of the utility model, a truncated cone-shaped base is coaxially fixed to the lower end of the support column. The lower bottom edge of the truncated cone is provided with a flange edge, which is fixed to the external ground by bolts passing through the flange edge. The base is hollow and is used to accommodate the folded protective airbag.

[0011] As a further improvement of the present invention, two mounting grooves for mounting handles are respectively provided on the upper side surface of the plate body near the two ends thereof.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figures 1 to 3As shown, a children's seesaw for passing levels in the present embodiment comprises a support column 1 and a plate body 2 hinged in the middle part to the upper end of the support column 1, and is characterized in that: a damping device 3 is provided between the plate body 2 and the support column 1 to damp the rotation of the plate body 2 about the hinge axis with the support column 1, and a protective airbag 4 is provided in the support column 1 near its lower end, and the protective airbag 4 is spread out after being inflated to form a square air cushion under the plate body 2, and the damping device 3 is a pneumatic damping device, and the damping device 3 is connected to the protective airbag 4 through a pipeline. In the process of using the seesaw of the present embodiment, it is only necessary to set the seesaw on the level-breaking route, and then in the process of children playing, the damping device 3 can slow down the turning of the plate body 2 to reduce the situation of children falling, and on the other hand, through the action of the protective airbag 4, a safety protection effect is achieved for children who fall, which greatly increases the safety of the seesaw.

[0018] As an improved specific implementation method, the support column 1 is hollow, and an air pipe 5 is vertically penetrated in the support column 1. A pipe is extended from the side of the air pipe 5. The end of the pipe passes through the side wall of the support column 1 to the outside to be connected to an external pumping and inflation device. Through the arrangement of the above structure, the inflation of the protective airbag 4 can be simply and effectively realized.

[0019] As an improved specific implementation method, a plurality of air holes 11 are opened on the side wall of the trachea 5, so that air can be filled into the protective airbag 4 through the air holes 11. Through the provision of the air holes 11, the air can be inflated toward the support column 1 by using an external pumping and inflation device, and the air holes 11 can be used to inflate the protective airbag 4.

[0020] As an improved specific implementation method, the damping device 3 is composed of two air buffer rods, which are respectively arranged on the left and right sides of the support column 1, one end of the two air buffer rods is hinged on the lower side of the plate body 2, and the other end is hinged on the left and right sides of the support column 1. The two air buffer rods are connected to the inside of the support column 1 through a pipeline, wherein the protective airbag 4 is made of elastic cloth. Through the setting of the above structure, it can be effectively realized that the protective airbag 4 and the damping device 3 use the same air source, so there is no need to set up an additional air source.

[0021] As an improved specific implementation, a truncated cone-shaped base is coaxially fixed to the lower end of the support column 1, and the lower bottom edge of the truncated cone is provided with a flange edge, which is fixed to the external ground by bolts passing through the flange edge. The base is hollow and is used to accommodate the folded protective airbag 4. The use of a truncated cone-shaped base can effectively increase the firmness of the support column 1 fixed to the external ground, and also provide a larger space for folding the protective airbag 4 in cooperation with the support column 1.

[0022] As an improved specific implementation, two mounting grooves for mounting handles are respectively provided on the upper side surface of the plate body 2 near its two ends. The mounting grooves can be used to install the handles. In this way, when there is no need to perform a level-breaking operation, the seesaw of this embodiment can reduce the air pressure in the protective airbag 4, thereby reducing the damping force of the damping device 3, and then the normal seesaw play can be achieved through the action of the handles.

[0023] In summary, the children's seesaw for passing levels in this embodiment can effectively protect children from falling by providing the protective airbag 4 and the damping device 3, and can slow down the turning speed of the board 2, thereby reducing the chances of children falling during the process of passing levels.

[0024] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
