Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a container for holding a pair of halves in a closed state, such as a main body and a lid, which are composed of a pair of halves. It relates to a stop device.

2. Description of the Related Art In a container and the like composed of a pair of halves such as a main body and a lid, each wall surface of the pair of halves comprises a protrusion having a different length, and a latch slidably wrapping the protrusion. A locking device that is brought into an engaged state or a disengaged state by sliding the latch is, for example, Japanese Utility Model Publication No. 53-3.
The one described in Japanese Patent No. 7997 is known.

DISCLOSURE OF THE INVENTION Problems to be Solved By the way, in the conventional container and the like as described above, concave portions are formed on both side surfaces of a protrusion formed on a wall surface of a pair of half bodies,
In addition, since the latch has a structure in which the protrusion of the latch is engaged with the recess so that the latch is slidable, it is possible to prevent the so-called rattling, which is an inconsistent engagement of the latch with the protrusion. Requires the latch to be tightly engaged with the protrusion, but on the other hand, because the latch slides smoothly, the assembly process for engaging the latch with the protrusion is easy. It is desirable that there is a considerable gap between the protrusion and the latch.

In view of such various problems in the conventional one, the present invention satisfies both of the contradictory requirements, and the latch is always aligned with the protrusion to ensure the locked state,
Moreover, it is an object of the present invention to provide a locking device for a container or the like, which enables smooth sliding operation and facilitates work for incorporating a latch.

Means for Solving Problems The present invention has the following technical means for achieving the object.

That is, the container locking device according to the present invention has protrusions having different lengths formed on the respective wall surfaces of a container composed of a pair of halves, and the latches slidable by enclosing both protrusions. In the locking device configured to provide the above-mentioned projections by sliding the latch and to release the engagement, the periphery of the latch is separated from the top plate part of the latch except the connection part with the top plate part. The present invention is characterized in that a spring portion is formed, and a sliding pressure contact portion for the projection is provided on the spring portion.

In the container locking device according to the present invention, when the latch is slid to the disengagement position, the engagement state of both protrusions is released, and one half body can be freely opened with respect to the other half body. The pair of halves are held closed by closing the pair of halves and sliding the latch to the engaged position. Further, the latch has a spring portion on its top plate, and the sliding pressure contact portion of this spring portion is in sliding contact with the protrusion, so that the latch maintains the alignment state with respect to the protrusion and smoothly performs the sliding operation. It can be performed.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

The illustrated container is made of plastic, and is composed of a pair of halves consisting of a main body 1 and a lid body 2 which can be opened and closed. Long protrusions 3 on the open side wall of the body 1
However, short projections 4 are formed on the open side wall surface of the lid body 2. 5 is a latch, and this latch 5
Encloses a long protrusion 3 and a short protrusion 4 and has one side 6
And an intermediate tongue 7 slidably engages the long protrusion 3 and the other side 8 engages the short protrusion 4.
That is, engaging grooves 9, 9'are formed on both side surfaces of the long protrusion 3, and engaging grooves 9, 9'are formed on one side surface 6 of the latch 5 and the tongue piece 7.
9'is formed with protrusions 10 and 10 ', and the engagement grooves 9 and 10' are formed.
The ridges 10 and 10 'engage with the 9'to allow the latch 5 to slide. An engaging groove 11 is also formed on one side surface of the short protrusion 4, and a protrusion that engages with the other side surface 8 of the latch 5 is formed.
Twelve are provided.

A spring portion 14 is formed on the top plate portion 13 of the latch 5 on the long protrusion 3 side. The spring portion 14 has a connecting portion 15 inside the top plate portion 13, and is formed in a tongue shape by cutting off the periphery excluding the connecting portion 15. 20 is the detaching part. At the open end of the spring portion 14 facing the long protrusion 3, a protrusion 16 which is slidably contacted with the upper surface of the long protrusion 3 is integrally provided. The protrusion 16 is elongated in the sliding direction. The upper surface of the latch 5 is formed on a lower surface except for the peripheral edge 17, and a cover 18 is fitted on the lower surface. The upper surface of the spring portion 14 is lower than the upper surface of the latch 5, and a gap 19 is provided with respect to the cover 18. The gap 19 is for keeping the spring portion 14 elastic. A cut portion 20 'is provided near the connecting portion 15 of the spring portion 14, and the cut portion 20' allows the spring portion 14 to have appropriate elasticity. Reference numeral 21 is a fitting hole of the cover 18, and the claw 18 'of the cover 18 is fitted into the fitting hole 21. Reference numeral 22 is a slide positioning spring piece, which is formed by a separating portion 22 ', and has a convex portion 23 at its free end so that when the latch 5 is slid to reach the locking position. The long projection 3 is engaged with the concave portion 24, and the state is surely maintained. The spring piece 22 may lock the latch 5 even in the open position.

In the above-described embodiment, since the latch 5 is elastically held in a tight state by the long protrusion 3 by the spring portion 14, the latch 5 always maintains a so-called rattling-free alignment state and is locked by the latch 5. The state is reliable, and the sliding operation can be performed smoothly. Further, since the latch 5 is supported by the long protrusion 3 by the spring portion 14, an appropriate gap can be provided between the two, and the assembly process for engaging the latch 5 with the long protrusion 3 is easy. .

Advantageous Effect of the Invention As described above, according to the present invention, protrusions having different lengths are formed on the respective wall surfaces of a container or the like composed of a pair of halves, and the protrusions are wrapped around to provide a slidable latch. In the locking device configured to engage and disengage the both protrusions by sliding the latch, a spring portion is provided on the top plate portion of the latch, the periphery of which is separated except for a connecting portion with the top plate portion. Since the spring portion is provided with a sliding pressure contact portion for the protrusion, the latch is always aligned with the protrusion to ensure the locked state, and the sliding operation can be smoothly performed. In addition, the effect that the work of assembling the latch is easy can be obtained.
