The invention relates to a push-type actuating device, in particular to a push-type telescopic pushing device.

The push-push button has a simple structure, and the lock/release switch can be achieved through a simple pressing action. Therefore, the double-push pressing structure is widely used as a small bolt or a fast pushing structure.

Taking the fast pushing structure as an example, its operating direction is usually along the axial direction of the pushing rod, directly pressing against the pushing rod. This pressing direction limits the configuration of the fast pushing structure. In addition, even in the locked state, the pushing rod must be properly exposed for the next pressing operation. In order to solve the above problems, the prior art is to use a motor instead of a fast pushing structure to drive the pushing rod, such as using a solenoid valve (Solenoid valve) or a motor to drive the pushing rod instead of directly pressing the pushing rod.

The buckle 110 has a first end surface 111 and a second end surface 112 opposite to each other. The push rod 120 and the actuating rod 130 are coaxially arranged on the buckle 110 and pushed in a stretching direction Y. The abutting rod 120 protrudes from the first end surface 111 , and the actuating rod 130 protrudes from the second end surface 112 . The actuating rod 130 is used to be pressed repeatedly along the telescopic direction Y, so that the pushing rod 120 moves between a protruding position P protruding from the first end surface 111 and a retracting position R retracting into the buckle seat 110 .

As shown in FIGS. 1 , 2 , 3 and 4 , the pressing mechanism 200 includes a pressing lever 210 , a cam member 220 and a steering unit 230 . The pressing rod 210 is movably disposed along a pressing direction X, and there is an included angle between the pressing direction X and the telescopic direction Y. Specifically, the angle between the pressing direction X and the stretching direction Y may be configured to be 90 degrees, but other angles are not excluded.

The first resetting member 300 is used for normally providing a pushing force to make the pressing rod 210 move away from the cam member 220 along the pressing direction X. When the pressing force on the pressing rod 210 disappears as shown in Figure 7, the thrust of the first reset member 300 makes the pressing rod 210 move away from the cam member 220 along the pressing direction X, so that the cam member 220 is driven to rotate reversely through the steering unit 230, and the apex is moved. 221 departs from the telescopic direction Y and returns to the state before the pressing rod 210 is pressed. At this time, due to the function of the double-push retractable mechanism 100 , the pushing rod 120 will maintain at the protruding position P. As shown in FIG.

The cam member 220 is approached on the circumference of the outer peripheral surface of the rotating sleeve 232 . When the protruding block 231 is located at the second end 233b, the protruding block 231 drives the cam member 220 to rotate, and moves the apex 221 to the telescopic direction Y to press the actuating rod 130 . Since the rotating sleeve 232 is disposed in the lower housing 402 , the first end 233 a can extend to the end of the rotating sleeve 232 to form an open state, so as to facilitate the installation of the pressing rod 210 and the protrusion 231 .
