Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
With reference to fig. 1-11, a push-button assembly with a safety mechanism comprises a push-button 1, and also elastic means 2 acting on said push-button 1, said elastic means 2 giving said push-button an upward tendency, said elastic means 2 being generally in the form of a compression spring.
The button comprises a button base 3, wherein the button 1 is sleeved in the button base 3, the button base 3 limits the button 1 to enable the button to move up and down and not to rotate, in the embodiment, a rotation stopping block 4 is arranged on the button 1, a rotation stopping groove 5 is formed in the side wall of the button base 3, and the rotation stopping block 4 is located in the rotation stopping groove 5 to achieve the purpose that the button 1 can only move up and down and not to rotate.
The knob 6 is also sleeved in the button 1, the knob 6 can rotate to a locking position and an unlocking position, the knob 6 is also connected with a reset mechanism, and the reset mechanism enables the knob 6 to have a tendency of rotating to the locking position. In this embodiment, the reset mechanism is a torsion spring 7, one end of the torsion spring 7 is connected to the knob 6, and the other end of the torsion spring 7 is connected to the button seat 3.
A safety mechanism and a positioning mechanism are further arranged between the knob 6 and the button 1, and when the knob is in a locking position under the action of the torsion spring 7, the button 1 is blocked by the safety mechanism so as not to be pressed down; when the knob 6 is rotated to the unlocking position, the knob 6 is positioned by the positioning mechanism so as to be kept at the unlocking position, at the moment, the safety mechanism no longer blocks the button 1, so that the button 1 can be pressed down, and the knob is still approximately positioned at the unlocking position under the positioning of the positioning mechanism after the button 1 is pressed down; when the button 1 is lifted back, the positioning mechanism does not position the knob 6 any more, and the knob 6 automatically returns to the locking position under the action of the reset mechanism.
In this embodiment, the safety mechanism includes a stopper 8 disposed in the knob 6 and protruding inward in the radial direction, and the button 1 is provided with a positioning block 9 corresponding to the stopper 8. When the knob 6 is rotated to the locking position, the positioning block 9 of the button 1 is positioned above the stop 8, so that the positioning block 9 is stopped by the stop 8; when the knob 6 is rotated to the unlocking position, the stop block 8 no longer blocks the positioning block 9, so that the button 1 can be pressed down.
