Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device capable of locking a body of a body and a lid.

[0002]

2. Description of the Related Art In order to strengthen a mechanism for locking a body of a body and its lid, a large locking device member may be used for each of the body and the lid.

[0003]

However, depending on the sizes of the main body and the lid, each member may not be as large and strong as desired. Therefore, an object of the present invention is to make it possible to reliably lock the main body and the lid body even if the locking portion on the body side is relatively small in the locking device.

[0004]

In order to solve the above problems, the present invention is characterized in that a fixed locking member having a first locking portion, a base end portion, a free end portion and the free end portion are provided. A movable locking member having a second locking portion that can be engaged with and disengaged from the first locking portion in the vicinity of an end portion, and the movable locking member that is located on both sides along the length direction of the movable locking member. And a fixed support member that pivotally supports the base end portion of the movable locking member so as to rotate in the first direction in which the spring rotates toward the side of the first locking portion and in the second direction opposite thereto. The fixed support member includes guide holes through which lock bars are inserted on both sides of the tip of the fixed support member facing the vicinity of the free end of the movable locking member, and the fixed support member facing the guide hole. Is located on the body side to which is fixed, and has an abutting portion with respect to the vicinity of the free end, and the movable locking member is There is a receiving portion for the lock rod between the free end portion and the second locking portion, the movable locking member pivots in the first direction, and the second locking portion causes the first locking member to move. The receiving portion is located between the guide hole and the abutting portion in a state in which the receiving portion is engaged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The lock device according to the present invention will be described in detail with reference to the accompanying drawings as follows.

[0006] The locking device 1 shown in a partially cutaway perspective view in FIG.
Is used for a container including a container body 2 and a lid 3 that opens by rotating in a clockwise direction P with respect to the container body 2. In the figure, the lid 3 is in a closed state, and is attached to the container body 2 via the locking device 1 so as not to open accidentally. If necessary, it can be locked with a virtual padlock 30. The lock device 1 is composed of a fixed locking member 5 attached to the container body 2 and a body 6 attached to the lid 3.

As is clear from the view taken along the line II-II of FIG. 1 shown in FIG. 2, the fixed locking member 5 is formed by bending a metal plate, and is substantially horizontal with the vertical mounting portion 7. Locking part 8
And the folded-back portion 9 at the tip of the locking portion 8, the mounting portion 7 is fixed to a required portion of the container body 2 with a screw or brazing.

The main body 6 includes a cover member 11 fixed to the lid 3 and an arm member 15 pivotally supported by a support shaft 12 of the cover member 11 and biased counterclockwise by a spring 13. The cover member 11 is fixed to a required portion of the lid 3 with a screw (not shown) at a mounting portion 14 extending along the outer surface of the lid 3 from the inner surface of the side wall portions 17 (see FIG. 1) on the left and right sides of the cover member 11. . Cover member 11
Has a top 16 covering a majority of the arm member 15, and an upper end curved to cover the support shaft 12 and the spring 13. The lower end of the top portion 16 has a raised portion 18 at the center in the width direction. The raised portion 18 is provided on the arm member 15 as indicated by an imaginary line.
It is formed to allow the turning of the required angle.
A guide hole 19 for receiving the lock rod 31 of the padlock 30 and a folded-back portion 20 inward of the cover member 11 are formed at the lower end of the side wall portion 17 (see FIG. 1).

The arm member 15 has a width wider than that of the fixed locking member 5 of the container body 2, and a guide hole 23 is formed in the middle of the upper and lower end portions 21 and 22, and an inner side formed by folding back a lower edge portion of the guide hole 23. And a wall 25. The lower end portion 22 is bent at an appropriate angle in a direction away from the container body 2 so that the tip portion thereof can be easily grasped. The lower end portion 22 of the arm member 15 in the state of FIG. 2 has its front surface 15A abutting against the folded-back portion 20 of the side wall 17, and is located between the folded-back portion 20 and the guide hole 19. The inner wall 25 is in a state of lightly contacting the locking portion 8 of the fixed locking member 5. However, the inner wall 25 and the locking portion 8 are adjusted in angle and clearance between them so as not to hinder the smooth turning of the arm member 15. When the lock rod 31 of the padlock 30 is inserted into the guide holes 19 of the left and right side walls 17, the arm member 15 is located between the lock rod 31 and the folded portion 20 of the side wall 17.

When the lid 3 is to be opened in FIG. 2, the locking portion 8 of the fixed locking member 5 is attached to the inner wall 25 of the arm member 15.
Collide. Therefore, the lid 3 is in a state in which turning in the P direction is blocked. The lid 3 can be opened by pivoting the arm member 15 to the position of the imaginary line so that the locking portion 8 and the inner wall 25 do not collide with each other. Also,
When the lock rod 31 of the padlock 30 is inserted into the guide hole 19, the arm member 15 that pivots in the clockwise direction abuts on the lock rod 31, and the pivoting to the position of the virtual line is blocked. Such lock rod 3
The insertion of 1 causes the locking device 1 to be locked.

[0011]

In the lock device constructed as described above, when a large force is applied to the arm member to forcefully open it in the locked state, the lock of the padlock supported by the side wall of the cover member. Since it is received by the rod, almost no force is exerted on the fixed locking member of the container body. Therefore,
The fixed locking member does not have to be large and rigid.
