The pressing rotary self-locking structure is composed of the axial tube 63 (the deep groove 66, the shallow groove 67 therein), the button column 42 (the bump 43 thereon, the sleek tooth structure 45), and the rotating pin 46 (the side body 482 and the italic body 483) are comprised.

The pressing rotation self-locking structure has the following two stationary states:

1) Unbraked state

At this time, the position of the button post 42 placed in the cylindrical hole 64 is at a higher position, and it can be considered that the projection 43 thereon moves to the tip end in the shallow groove 67. The side body 482 on the rotating pin 46 is displaced into the deep groove 66 and placed at the top end of the deep groove 66 by the button return spring 49.

Since the upper button post 42 and the rotating pin 46 do not press the brake substrate 5 below it, and there is a certain gap therebetween, the brake substrate 5 moves upward by the brake return spring 28 and The lower end of the brake disc pin 51 thereon is disengaged from the positioning hole 21, thereby being in an unbraked state.

2) Brake status

At this time, the bump 43 on the button post 42 is still located at the lower end of the shallow groove 67, and the rotating pin 46 is disengaged from the deep groove 66 due to the downward pressing of the button post 42, but due to the rounded tooth structure disposed at the lower end surface of the button post 42 The portion of the italic body 483 with the top surface of the rotating pin 46 is in an unstable state by the button return spring 49, and since the projection 43 of the button post 42 is caught in the shallow groove 67, it is impossible to rotate, and therefore, the forcing The rotating pin 46 is rotated at an angle such that the top end of the italic body 483 is placed between the two teeth in the rounded tooth structure 45. By properly designing the angle of rotation thereof, the latch on the rotating pin 46 can be placed in the barrel. The lower end surface of the groove wall 65 (the groove wall 65 corresponding to the shallow groove 67) in the hole 64, whereby the rotation pin 46 presses downward and presses the brake substrate 5 downward, so that the lower end of the brake disk pin 51 is inserted into the turntable In the positioning hole 21 on the second side, the turntable 2 is prevented from rotating and is in a braking state.

The process of pressing the rotary self-locking structure is as follows:

1) Brake

The upper end of the button post 42 is pressed down, the bump 43 thereon moves downward along the shallow groove 67, and the rounded tooth structure 45 at the lower end of the button post 42 is pressed against the italic body 483 of the ramp tooth portion 48 of the release pin. Up and forcing the rotation pin 46 to move downward. When the side body 482 of the ramp tooth portion 48 on the rotation pin 46 moves out of the deep groove 66, the between the rounded tooth structure 45 and the italic body 483 In the steady state, under the action of the restoring force of the button return spring, the unstable state seeks a steady state, so that in the case where the button post 42 cannot be rotated, the rotating pin 46 is rotated by an angle so that the italic portion 483 on the rotating pin 46 The card is placed on the lower end surface of the shallow groove 67. As described above, the brake substrate 5 is moved downward so that the lower end of the brake disc pin 51 is inserted into the positioning hole 21.

2) Release the brakes

Pressing the upper end of the button post 42 downward again, the bump 43 thereon continues to move downward along the shallow groove 67, and the rounded tooth structure 45 at the lower end of the button post 42 is pressed against the ramp tooth portion 48 of the release pin. The iterative body 483 forces the rotation pin 46 to continue to move downward. When the italic body 483 of the ramp tooth portion 48 on the rotation pin 46 moves out of the lower end surface of the shallow groove 67 and passes over the lower end surface of the groove wall 65 on the deep groove 66 side, the sleek The unstable state between the toothed structure 45 and the italic body 483, under the action of the restoring force of the button return spring, the unstable state seeks a steady state, so that the rotation pin 46 is rotated in the case where the button post 42 cannot be rotated. The angle is again rotated by an angle in the direction of the direction of rotation of the brake so that the side body 482 on the rotating pin 46 is located on the lower port of the deep groove 66. At this time, the pressure pressed against the upper end of the button post 42 is released, and the pin 46 is rotated. The side body 482 moves upward along the deep groove 66. Thus, the rotation of the rotating pin 46 causes the brake substrate 5 to move upward, so that the lower end of the brake disk 51 is pulled out from the positioning hole 21, and as a result, the brake is released.

The above two steps are alternated to allow the structure to change between braking and braking.
