Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a fitting device for accurately fixing a moving body to be deployed at a predetermined position.

[Conventional technology]

A conventional fitting device of this type has a structure as shown in FIG. In FIG. 3, (1) is a moving body, (2) is a fixed body, (3) is a latch pin, (4) is a spring for pushing the latch pin (3), and (5) is a latch hole into which the latch pin (3) is inserted. , (6) is a latch holder, and (7) is a latch block for receiving the latch holder (6).

The latch holder (6) moves according to the movement of the moving body (1) and collides with the latch block (7). At the same time, the latch pin (3) is pushed out by the spring (4) and inserted into the latch hole (5), so that the moving body (1) is fixed to the fixed body (2).

[Problems to be solved by the invention]

When the conventional fitting device is used to fix the object to be deployed, the latch pin (3) moves along with the movement of the moving body (1) until the latch holder (6) hits the latch block (7). Exercise while hitting the top. Therefore, when a plurality of fitting devices are used with the same deploying force, there is a problem that the drag force against the deploying becomes large.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a fitting device in which the latch pin can be fitted to the moving body without sliding.

[Means for solving problems]

The fitting device according to the present invention is housed in the cavity of the fixed body so as to be movable in the direction perpendicular to the movement direction of the moving body having the latch hole, and has a pin hole formed perpendicularly to the axial direction. And a latch pin whose one end is fitted in the latch hole at the time of latching, and a latch pin which is mounted on the side of the fixed body on the moving direction side of the moving body and which corresponds to the pin hole of the latch pin, A leaf spring whose one end facing the body is an open end, and one end of which is engaged with a pin hole of the latch pin and the other end of which is projected outward from the hole of the leaf spring. A holding pin for holding the latch pin such that one end of the latch has a predetermined gap with respect to the moving body, a spring provided on the cavity of the fixed body, and biasing the latch pin toward the moving body, and the moving body. Is installed in The open end of the leaf spring is pushed along with the movement of the moving body, and the other end of the holding pin is released from the hole of the leaf spring when the latch hole of the moving body is in the position for fitting with the latch pin. It is equipped with a block for.

[Action]

In this invention, a holding pin keeps one end of the latch pin at a predetermined gap from the moving body by a holding pin until the moving body moves and a latch hole of the moving body comes to a position where the latch hole fits with the latch pin. It enables the unfolding movement without sliding, and the latch hole of the moving body fits with the latch pin and has a pin hole formed perpendicular to the axial direction. Further, the holding pin (7) is positioned such that one end thereof engages with the pin hole of the latch pin (3) and the other end thereof projects outward from the holding hole (11) of the leaf spring (8). The latch pin (7) is held so that one end of 7) has a predetermined gap with respect to the moving body (1). Further, the connection block (6) pushes the leaf spring (8) while engaging with the connection hole (10) provided at the open end of the leaf spring (8) in accordance with the movement of the moving body (1), and the latch hole of the moving body. It serves to release the other end of the holding pin (7) from the hole of the leaf spring (8) when (5) is in a position to be fitted with the latch pin (3).

In the fitting device configured as described above, as shown in (a) and (b) of FIG. 1, before the fitting of the moving body (1) and the fixed body (2), the latch pin (3) is attached. The latch pin (3) is held by the fixed body (2) by engaging the fixed holding pin with the hole of the leaf spring (8). The moving body (1) moves as shown in (a) and (b) of FIG.
When approaching the contact surface (9), the connecting block (6) enters the hole (10) of the leaf spring (8) and lifts the leaf spring (8). As a result, the holding pin (7) is released from the hole of the leaf spring (8) and the holding state is released. Therefore, the latch pin (3) is moved by the spring (4) to the latch hole (5) of the moving body (1). The moving body (1) is fixed to the fixed body (2) by the latch pin (3) and the contact surface (9).

Although there is one latch pin (3) as shown in FIGS. 1 (a) and (b) and FIGS. 2 (a) and (b),
The number of latch pins may be increased in the direction parallel to the leaf spring.

[Effect of device]

As described above, according to the present invention, since the latch pin is engaged with the fixed body side using the holding pin and the leaf spring until just before the fitting, there is no resistance due to the sliding between the moving body and the latch pin as in the conventional case. By connecting the connection block and the leaf spring at the time of fitting, the movement of the moving body in the axial direction of the latch pin with respect to the fixed body can be fixed.
