DETAILED DESCRIPTION

[0018] In the following description, a lot of specific details are set forth in order to facilitate a thorough understanding of the utility model. However, the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, so the utility model is not limited to the specific embodiments disclosed below.

[0019] Example 1

[0020] As Figures 1-4As shown, a multi-mode playing device for children's dental chair comprises a support 1 and a display screen 2. The support 1 is rotationally connected with the children's dental chair and can rotate 360 degrees in a horizontal plane. The support 1 is provided with a transverse support portion at the top end, and the transverse support portion is connected with an up-down telescopic rod 3 at the end. The up-down telescopic rod 3 is connected with a universal rotating U-shaped seat 4 at the end, the U-shaped seat 4 is provided with a vertical rotating display screen seat 5 inside, and the display screen 2 is arranged on the display screen seat 5.

[0021] Based on the above structure, the display screen 2 can be conveniently adjusted in front-back, up-down, left-right or pitch angle to adapt to the body position of the child on the dental chair without worrying about hurting the eyes. The display screen 2 is integrated with a touch module, a voice module and a sound module. By means of the voice module, the display screen 2 can play soothing songs, stories or cartoon through voice instructions or the crying sound of the child.

[0022] The up-down telescopic rod 3 comprises a sleeve-connected inner tube 31 and an outer tube 32. The inner tube 31 is provided with a gourd-shaped through hole 311 (i.e. a plurality of circular holes are connected through a smaller strip-shaped hole) on one side in the axial direction, and the side wall of the outer tube 32 is provided with a radial locking bolt 33 inserted into the through hole 311. The shaft of the radial locking bolt 33 is provided with a large shaft section 331 and a small shaft section 332. The large shaft section 331 cannot pass through the gourd neck of the through hole 311, and the outer diameter of the small shaft section 332 is smaller than the width of the gourd neck of the through hole 311. A spring 34 is sleeved on the shaft of the radial locking bolt 33 to keep the large shaft section 331 clamped with the through hole 311, and after pressing the radial locking bolt 33, the small shaft section 332 is located in the through hole 311.

[0023] In this way, in the normal state, the large shaft section 331 is located in the through hole 311 of the inner tube, and the inner tube 31 is clamped and cannot be up-down telescopic; when telescopic is needed, the radial locking bolt 33 is pressed, the spring 34 is compressed, the radial locking bolt 33 moves into the inner tube 31, and the small shaft section 332 is located in the through hole 311, at this time the gourd neck of the through hole 311 can smoothly pass through the small shaft section 332, so that the telescopic of the inner tube 31 can be realized; after adjusting the height, the radial locking bolt 33 is released, the radial locking bolt 33 moves to the outside of the outer tube 32 under the action of the spring 34, and the large shaft section 331 enters the through hole 311 to realize the locking of the inner tube 31.

[0024] The outer wall of the inner tube 31 and the inner wall of the outer tube 32 are provided with a telescopic guide structure, which can guide the correct telescopic of the inner tube 31 and avoid the rotation of the inner tube 31. Specifically, the telescopic guide structure comprises a guide block 312 arranged on the outer wall of the inner tube 31 and a guide groove 321 arranged on the inner wall of the outer tube 32 in the axial direction, and the guide block 312 is slidingly arranged in the guide groove 321. It should be noted that the positions of the guide block and the guide groove can also be exchanged, and similar structure changes shall be within the protection scope of the utility model.
