Detailed Description
The invention is further explained below with reference to the drawings.
As shown in fig. 1 and 2, a push-push type telescopic device comprises a guide groove sleeve, a spring and a telescopic rod. The inner side wall of the guide groove sleeve is provided with a section of guide groove, the initial end of the section of guide groove is close to the port of the guide groove sleeve, the final end of the guide groove is far away from the port of the guide groove sleeve, the initial end and the final end of the guide groove are respectively provided with a standing point groove, the depth of the standing point groove is larger than that of the guide groove, and the joint of the standing point groove and the guide groove is smooth radian. The guide groove is an arc-shaped groove with the radian less than or equal to 360 degrees, and the distance from the farthest end of the arc-shaped groove along the axial direction of the guide groove sleeve to the port of the guide groove sleeve is greater than the distance from the standing point groove to the port of the guide groove sleeve, as shown in fig. 3. In this embodiment, the arc of the guide slot segment between the most distal end of the arcuate slot along the axial direction of the guide slot sleeve and the standing point slot is about 30 °. The spring is positioned in the guide groove sleeve, and the telescopic rod stretches into the guide groove sleeve from the port of the guide groove sleeve. The side of the telescopic rod is provided with a guide pin hole perpendicular to the axis of the telescopic rod, the guide pin hole is internally connected with a guide pin matched with the guide groove through a guide pin spring, the section of the guide groove is arc-shaped, the end part of the guide pin is spherical, and the guide pin slides between the starting end and the finishing end of the guide groove.
The end of the telescopic rod is provided with a connecting piece, which in the embodiment is a ball seat and can be matched with the ball rod piece. The ball head of the ball head rod piece is arranged in the ball seat at the end part of the telescopic rod, and the ball head of the ball head rod piece can move freely by 360 degrees relatively. The ball rod piece is pushed along the axial direction of the telescopic rod, the ball rod piece pushes the telescopic rod into the guide groove sleeve through the ball seat, at the moment, the guide pin on the side face of the telescopic rod slides into the guide groove from the standing point groove at the initial end, the telescopic rod is rotated to be deep into the guide groove sleeve along the guide groove under the guide of the guide groove, when moving to the deepest point of the guide groove, namely moving to the farthest end of the arc-shaped groove along the axial direction of the guide groove sleeve, the telescopic rod continuously rotates along the guide groove and moves out of the guide groove sleeve for a small distance due to the inertia effect, when the guide pin slides into the standing point groove at the final end of the guide groove, the thrust exerted by the ball rod is stopped, the telescopic rod stays at the current position, and the spring is in a compressed energy storage state, as shown in fig. 4, 5 and 6.
When the telescopic rod is required to be pushed out to return to the initial state, the telescopic rod is only required to be pushed inwards, so that the guide pin slides out of the standing point groove and enters the guide groove, the telescopic rod rotates to move and compress the spring, under the action of inertia, after the guide pin passes through the deepest point of the guide groove, external force is stopped, the telescopic rod rotates outwards under the action of the spring to extend out of the guide pin to reach the starting end standing point groove, and then the spring is in a relaxed state, so that pushing-out action is completed, as shown in fig. 7.
In the above embodiment, the standing point groove is deeper than the guide groove and is combined with the guide groove in a transition gentle slope manner, so that the guide pin can slide between the guide groove and the standing point, and the guide pin can stay in the standing point and can move out of the standing point with relatively small external force. When the standing-point groove is not arranged at the starting end of the guide groove, the telescopic rod can be prevented from sliding out by arranging a limiting structure at the end part of the guide groove sleeve. The number of the guide grooves and the guide pins can also be multiple groups, so that the guide grooves and the guide pins can bear larger load.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
