Abstract

PURPOSE:To surely engage a lock board even when some dimensional error is present between a lock board engaging part and the lock board. CONSTITUTION:A square projection 7 having a height larger than the thickness of a lock board 6 is provided on the rear end surface of a shaft 4, and the lock board 6 having an inducing part on its forward end is mounted to the projection 7 through a spring member. As a result, the lock board 6 is allowed to move back and forth under the resilience of the spring member, and hence locking can always be made surely even if there is some dimensional error.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box handle which is mainly attached to a door of a box such as a box for storing electric equipment and which is locked by a locking plate.

[0002]

2. Description of the Related Art A conventional handle attached to a door of a box or the like and locked by a locking plate is, for example, Jikkei 3-192.
As disclosed in Japanese Patent Publication No. 49, a lock plate is fitted to the rear end of a shaft rotated by a handle and fixed by bolts and nuts.

[0003]

However, in such a conventional handle, since the locking plate is fixed to the shaft by the bolts and nuts without rattling, the box body and the door are not attached when assembled in boxes. It was necessary to perform complicated correction work such as bending the tip of the locking plate in accordance with the dimensional error of. Further, the tip of the locking plate strongly hits the locking plate locking part of the box body during use, the coating on that part may peel off, and the handle may not rotate smoothly. The present invention solves the above problems and does not require a complicated correction work even if there is a slight dimensional error between the box body and the door, and handles of the boxes can be smoothly rotated. It was made to provide.

[0004]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, has a structure in which a rear end surface of a shaft rotated by a handle is provided with an angular projection having a thickness higher than the thickness of a locking plate, and a tip thereof is provided. It is characterized in that a locking plate having a guiding portion is fitted to this angular projection and is elastically attached via a spring material.

[0005]

The lock plate of the present invention is attached to the rear end surface of the shaft with a spring member interposed, and the plate thickness of the lock plate is made thinner than the height of the angular protrusions to ensure elasticity. . Therefore, when the shaft is rotated, even if there is a slight dimensional error between the locking plate locking part of the box body and the locking plate due to variations in sheet metal processing, the tip of the locking plate is guided. With the guiding function of the part, the whole locking plate elastically moves,
It can be smoothly locked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 denotes a vertically long main body fixed to a door of a box or the like. The main body 1 has a shallow concave portion 2 for storing a handle on a front surface thereof, and a bearing portion 3 protruding from the upper rear portion of the concave portion 2. There is. Reference numeral 4 denotes a handle shaft that is rotatably supported by the bearing portion 3, and a flat plate-like handle 5 is attached to the front side of the handle so that the handle 5 can be undulated.

On the rear end surface of the shaft 4, there is provided a protrusion 7 for attaching a locking plate 6. The angular protrusions 7 are formed slightly higher than the thickness of the locking plate 6. A square mounting hole 8 is formed at the base of the locking plate 6, and the rotation of the shaft 4 is surely transmitted to the locking plate 6 by fitting the square mounting hole 8 into the square protrusion 7. It has a structure. Further, as shown in FIG. 3, a slightly inclined guiding portion 14 is formed at the tip of the locking plate 6.

A screw hole 9 is provided at the center of the angular protrusion 7, and the locking plate 6 is attached with a bolt 10. This bolt 10 is provided with a flange portion 11, and by interposing a spring member consisting of a corrugated spring washer 12 having a claw 15 for engaging with the bolt 10 between the flange portion 11 and the locking plate 6. The locking plate 6 is elastically attached to the angular protrusion 7. As described above, since the height of the angular protrusion 7 is larger than the thickness of the locking plate 6, the bolt 1
Even if 0 is tightened, the locking plate 6 can secure elasticity at the peripheral edge of the angular protrusion 7. The corrugated spring washer 12 of the embodiment is provided with through holes 13 at a required interval in order to secure elasticity on average when tightened.

With this construction, the main body 1 is used by attaching it to the door 21 of a box or the like, and the locking plate 6 is fitted to the angular projection 7 of the shaft 4, so that the handle When the shaft 4 is rotated by 5, the locking plate 6 also rotates and engages with the box body 22 for locking. At this time, even if there is a slight dimensional error between the position of the locking plate 6 and the locking plate locking portion of the box body 22 due to variations in sheet metal processing, the guiding portion 1 at the tip of the locking plate 6
4 acts as a guide, and the entire locking plate 6 is the shaft 4
Since it moves elastically with respect to, the locking operation can be performed smoothly. Moreover, because of the elastic force, the locking plate 6 presses the locking plate locking portion of the box body 22 with a stable force, so that the force required for rotating the handle 5 can be stabilized.

[0010]

As is apparent from the above description, the present invention ensures that the locking plate 6 is always properly attached to the locking plate locking portion 23 of the box body 22 while the spring material consisting of the wavy spring washer 12 is elastically resilient. Since the lock plate 6 is locked, even if there is a slight dimensional error between the lock plate locking portion 23 and the lock plate 6 due to variations in sheet metal processing, it is necessary to correct the lock plate 6 as in the conventional case. Absent. In addition, the handle 5 can be rotated lightly and smoothly, and the locking plate 6 does not forcibly bite into the locking plate locking portion 23 of the box body 22, so that the peeling of the coating on that part can be prevented. Therefore, the present invention greatly contributes to the industry by solving the conventional problems.
