Specific implementation mode
Further explanation is done to the present invention below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of push-push telescopic device, including guide groove set, spring, telescopic rod.Guide groove covers madial wall
It is equipped with one section of guide groove, the initiating terminal of this section of guide groove leans on the port of close guide groove set, the port that the destination terminal of guide groove is covered far from guide groove,
The initiating terminal and destination terminal of guide groove are respectively equipped with stationary point slot, and stationary point groove depth is more than channel depths, the connection of stationary point slot and guide groove
Place is smooth radian.Guide groove is that the radian extended from initiating terminal to destination terminal is less than or equal to 360 ° of arc groove, and arc groove edge is led
The distance for the port that the distalmost end of slot set axis direction is covered to guide groove is more than the distance for the port that stationary point slot is covered to guide groove, such as Fig. 3
It is shown.In the present embodiment, guide groove section radian about 30 ° of the arc groove between the distalmost end and stationary point slot that guide groove covers axis direction.
Spring is located in guide groove set, and telescopic rod gos deep into from the port that guide groove covers in guide groove set.Contracting bar side face is equipped with vertical telescopic rod axis
Pin-guide hole, the guide pin being adapted to guide groove is connected by pilot pin spring in pin-guide hole, guide groove section is arc-shaped, and guide pin end is
Spherical shape, guide pin slide between the initiating terminal and destination terminal of guide groove.
The end of telescopic rod is equipped with connector, and the connector is ball seat in the present embodiment, can coordinate work with bulb rod piece
Make.The bulb of the bulb rod piece is placed in the ball seat of telescopic rod end, between the two can with respect to 360 degree free movements.Along flexible
The axial of bar push bulb rod piece, bulb rod piece that telescopic rod is pushed into guide groove set by ball seat, and telescopic rod side is led at this time
Pin slides into from the stationary point slot of initiating terminal in guide groove, and under the guiding of guide groove, telescopic rod is deep into along guide groove rotation in guide groove set
Portion, when the deepest point for moving to guide groove, that is, when moving to distalmost end of the arc groove along guide groove set axis direction, since inertia is made
With telescopic rod continues to move segment distance along guide groove rotation and toward guide groove set is outer, when guide pin slides into the stationary point slot of guide groove destination terminal
When, stop the thrust that applies by ball rod, telescopic rod rests on current location, and spring is in compressed energy-storage state, as Fig. 4,
Shown in Fig. 5, Fig. 6.
When returning to original state, only telescopic rod need to be inwardly pushed when needing to release telescopic rod so that guide pin skids off stationary point
Slot simultaneously enters in guide groove, and telescopic rod rotates movement and compressed spring, under effect of inertia, when to cross guide groove most deep for guide pin
After point, stop applying external force, telescopic rod rotates outward to reach when guide pin reaches initiating terminal stationary point slot and stop under the action of the spring
It only moves, spring is in diastole state at this time, completes projecting motion, as shown in Figure 7.
In above-described embodiment, stationary point slot is deeper than guide groove processing and has transition gentle slope to be combined between guide groove, makes guide pin can
It is slided between guide groove, stationary point, guide pin can rest in stationary point and can remove stationary point with smaller external force.When rising for guide groove
When beginning is not provided with stationary point slot, telescopic rod can prevent it from skidding off by covering end set position limiting structure in guide groove.Guide groove and guide pin
Quantity can also be multigroup, the load of bigger can be born.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
