(Problem) In the conventional locking device described above, when the locking device R is attached to a surface that has an extremely small slope with respect to the sealing surface 58 of the floor and the engine cover 56 is locked, as shown in FIG. 56
is drawn to the locking device R via the ring receiver 57 in an approximately horizontal direction. Therefore, there was a problem in that almost no vertical pressing force was applied to the seal rubber 59 provided at the edge of the cover 56, and the sealing performance between the seal rubber 59 and the seal surface 58 was extremely poor.

(Means for Solving the Problems) The present invention was devised in view of the above problems, and its gist is to provide a lock handle rotatably supported on a body side fixing member via a support shaft. a ring rotatably supported on the lock handle via a swing shaft; and a ring holder attached to a mating member that is attached to and detached from the body-side fixing member and to which the ring is locked when the lock handle is locked. When the lock handle is rotated about the support shaft and is locked by coming into contact with the body-side fixing member, the swing shaft is rotated about the support shaft and is rotated more than the support shaft. The lock device is positioned close to the body-side fixing member, and the ring turns over accordingly, drawing and locking the ring receiver toward the body-side fixing member, wherein the body-side fixing member is connected to the support shaft. A link is provided on the ring receiving side and rotatably supported via a link shaft disposed at a higher position than the support shaft, and the free end side of this link is the free end side of the ring. They are rotatably connected, and the rotation range of the free end side of the ring is restricted to the rotation locus range of the free end side of the link, and the free end side of the ring is latched and locked to the ring receiver. In the locked state, the free end of the link presses the ring receiver in a substantially vertical direction, thereby locking the mating member against the body.

(Function) In the lock device, the ring receiver is pulled in a substantially horizontal direction via the ring, and receives a pushing force in a substantially vertical direction from the free end side of a link connected to the free end side of the ring. That is, the ring is rotatably supported on the lock handle via a swing shaft, and when the lock handle is rotated about the support shaft when the ring is locked, its free end side moves downward. In that case, the free end side of the ring is connected to the free end side of the link rotatably supported by the body side fixing member, so the free end side of the ring follows the rotation locus of the free end side of the link. move downward. Therefore, the free ends of the links also move downward and come into contact with the ring receiver. Since the link rotates around the link shaft, which is on the ring receiving side of the support shaft and located higher than the support shaft, the ring receiver is pressed from above in an almost vertical direction. It is pressed against the lower body side and locked.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In this example, as shown in FIG.
An example of a locking device R is shown below. One end side of the cover C, which is covered above the battery B, is pivoted by a hinge H, and the cover C can be opened and closed. The other end of the cover C is locked to the floor F by a locking device R. This locking device R is the fourth
As shown in the figure, it is attached to the slightly inclined surface of the floor F.

The details of this locking device will be explained based on FIGS. 1 and 2. The body side fixing member 1 is fixed to the inclined surface 8 of the floor F, and the bottom surface thereof is fixed to the inclined surface 8. The rear end forms a protruding piece 1a that is inclined upward, and the entire body is formed in a dogleg shape.

A lock handle 3 is rotatably supported on the body side fixing member 1 via a support shaft 2.
A square bar-shaped ring 4 is rotatably supported on the lock handle 3 via a swing shaft 4a located forward of the support shaft 2 (on the left side in the drawing).
The swing shaft 4a is set to be closer to the body-side fixing member 1 than the support shaft 2 when the lock handle 3 comes into contact with the body-side fixing member 1 to be in the locked state.

A link shaft 6a is installed horizontally near the upper end of the projecting piece 1a of the body-side fixing member 1, and rod-shaped links 6 are rotatably connected to the body-side fixing member 1 at both ends of the link shaft 6a via the link shaft 6a. is supported by That is, the attachment position of the link shaft 6a is closer to the ring receiver 5 (described later) than the support shaft 2, and is located higher than the support shaft 2.

Note that the free end side 6b of the link 6 is rotatably connected to the free end side 4b of the ring 4. Therefore, the rotation range of the free end side 4b of the ring 4 is restricted to a rotation trajectory range centered on the link shaft 6a of the free end side 6b of the link 6.

In the figure, reference numeral 5 denotes a ring receiver, which is attached to the outer side of the free edge of the cover C, and is latched to the free end side 4b of the ring 4 when the locking device R is locked.

In the figure, reference numeral 9 denotes a seal rubber attached to the end of the cover C, which comes into contact with the sealing surface 7 of the floor F to form a seal between the cover C and the sealing surface 7.

In this example, the angle θ° between the inclined surface 8 of the floor F and the sealing surface 7 is close to horizontal (180°>θ°>
90°).

In the locking device of this embodiment constructed as described above, the lock handle 3 is rotated about the support shaft 2 and is locked by coming into contact with the body side fixing member 1. At this time, the swing shaft 4a is rotated about the support shaft 2 and is positioned closer to the body-side fixing member 1 than the support shaft 2 is. In that case, the swing shaft 4a side of the ring 4 turns over the support shaft 2, the free end side 4b of the ring 4 moves downward and is drawn toward the body side fixing member 1 side, and the free end side 4b of the ring 4
The ring receiver 5 is locked to b and pulled. In that case, since the free end side 4b of the ring 4 is connected to the free end side 6b of the link 6, it descends along the rotation trajectory of the free end side 6b of the link 6, and the free end side 6b of the link 6 also moves downward. It moves downward and is stopped by the ring receiver 5. According to the pulling force of the ring 4 in the horizontal direction, the free end side 6b of the link 6 presses the ring receiver 5 in a substantially vertical direction from above, and the ring receiver 5 receives the pulling force in the horizontal direction and at the same time in the vertical direction. Receives pressing force. Therefore, the sealing rubber 9 of the cover C is pressed against the sealing surface 7 of the floor F, and is securely sealed at the same time as the locking.

(Effects) The present invention includes a lock handle rotatably supported on a body-side fixing member via a support shaft, a ring rotatably supported on the lock handle via a swing shaft, and A ring receiver is attached to a mating member that is attached to and detached from the body-side fixing member, and the ring is locked when the lock handle is rotated about the support shaft and comes into contact with the body-side fixing member. When the ring is locked, the swing shaft is rotated about the support shaft and is positioned closer to the body-side fixing member than the support shaft, and the ring is accordingly turned over and the ring receiver is rotated. A locking device that draws and locks the body-side fixing member toward the body-side fixing member, and the body-side fixing member is connected to the body-side fixing member via a link shaft that is located on the ring receiving side and higher than the support shaft. A rotatably supported link is provided, the free end side of this link is rotatably connected to the free end side of the ring, and the rotation range of the free end side of the ring is set to the free end side of the link. In a locked state in which the free end side of the ring is latched and locked to the ring receiver, the free end side of the link presses the ring receiver in a substantially vertical direction; By configuring the mating member to be locked on the body side, even if the floor surface to which the locking device is attached has a slight inclination, the object to be locked, such as the cover to be locked, can be pressed from a substantially vertical direction. It has the effect of being able to securely seal and lock onto the floor surface.
