Description

[Brief explanation of the drawing]

FIG. 1 is a front view of the device of the present invention, with a part thereof cut away, and FIG. 2 is a diagram showing the device of FIG. 1 cut along the line Y-Y shown in the same figure. FIG. 3 is a sectional view taken in the direction of the arrow, showing the apparatus shown in FIG. 2 in a state in which the slide is lowered.

Claims (1)

[Claims for Utility Model Registration] A housing having a rotating shaft that is reciprocated around the axis over a certain angular range by a drive device, and a top wall and a bottom wall that face each other with a cavity in between; a slide attached to the bottom wall of the housing so as to make reciprocating linear motion in the vertical direction with respect to the housing, and having a concave groove with a semicircular cross section formed on the upper surface; The semi-circular cross section is disposed between the lower surface of a plate fixed to the shaft, is slidably held against the lower surface of the plate and the surface of the concave groove, and has a downwardly bulging cross section. a first sliding member; a first sliding member that is placed on the upper surface of the plate so as to be symmetrical with the first sliding member with respect to the plate, and that has an upside-down shape; and a block disposed above the second sliding member and having a concave groove with a semicircular cross section formed on the lower surface', and the cross section bulges upward. The second sliding member has a semicircular shape and is slidable on the upper surface of the plate and the surface of the concave groove of the block, and further has one end fixed to the slide and the other end fixed to the housing. a connecting rod supported by the top wall and capable of reciprocating vertically with respect to the housing; and a retaining ring mounted on the connecting rod and disposed above the block; A collar that cannot be moved downwardly with respect to the connecting rod, and a collar that is compressed between a spring receiver provided on the connecting rod and the collar, and when compressed, exerts elasticity on the spring receiver. and a spring capable of pulling the slide upward and press-fitting the slide into engagement with the first sliding member, and the retaining ring is configured such that when the slide is pushed downward, the spring causes the spring to elastically press against the collar. is attached to the connecting rod in a position where the collar is not pressed against the block by pressing the collar, and when the rotating shaft rotates in a direction to lower the plate.
In this case, the plate presses the slide through the first sliding member to lower it, and the spring also lowers together with the threaded rod, but the spring presses against the block through the collar. The block lowers with a gap formed between it and the collar, and when the rotary shaft rotates in the direction of raising the plate, the plate moves up the second sliding surface. The spring is compressed by pressing the collar through the member and the block, and the elastic force causes the slide to rise together with the first sliding member. A device that converts the motion into reciprocating linear motion.
