[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for locking a lid of a pneumatic pot.

[0002]

2. Description of the Related Art Conventionally, a pneumatic pot uses a shoulder member connected to the upper end of an exterior case surrounding an inner container, and a receiving portion provided at the center of the shoulder member with an opening communicating with a wide opening of the inner container. And a beak communicating with the upper end of the receiving portion is provided at the front of the receiving portion, and a hinge portion is provided at the rear of the receiving portion.

[0003] On the upper surface of the shoulder member, there is provided an upper lid and a lower lid with a built-in bellows pump, and a hinged lid is provided at the hinge portion of the shoulder member, and a discharge mechanism for discharging the liquid in the inner container to the outside is provided. A bottom member is connected to the lower end of the outer case, and air is pressure-fed into the inner container by pressing a bellows pump to discharge the liquid in the inner container to the outside via a discharging mechanism.

A locking groove for a locking claw is provided at the upper end of the beak of the shoulder member. A lid for opening and closing the opening of the receiving portion is detachably mounted on the upper surface of the shoulder member. A hole for a lock claw is formed in the front wall of the lower lid behind the lock groove for the lock claw of the shoulder member.

A lock claw is formed by forming a long hole in the front upper wall of the upper cover of the cover body, and the locking device penetrating through the lock claw hole of the lower cover and locking in the locking groove for the lock claw of the shoulder member. A lock body having a lock body, a lock body contact plate for restricting backward movement of the lock body, and one end contacting the lock body, and the other end contacting the lock body contact plate so that the lock claw of the lock body is always used for the lock claw. A spring locked in the locking groove and an operation knob that slides along the long hole of the upper lid and contacts the lock body to slide the lock body are provided.

When the operation knob is slid backward and upward along the long hole of the upper lid of the lid, the lock claw of the lock body is separated from the lock claw locking groove of the shoulder member, and the receiving portion opening of the shoulder member is opened. The lid was more open.

[0007]

[Problem to be solved by the invention] In this kind of pot,
The structure of the lock device that opens and closes the lid on the upper surface of the shoulder member is complicated, the number of assembly parts is large, and the cost increases,
In assembling, the lock body and the lock body contact plate are temporarily fixed to the lower lid, and a spring has to be stretched between these narrow parts, which has a problem that the operation is extremely complicated.

The present invention has been made to solve the above problems, and has a simple structure, a very small number of assembly parts, and can be easily assembled and disassembled without complicated assembly work. The efficiency can be improved and the cost can be significantly reduced. Another object of the present invention is to provide a pneumatic pot that can reliably and smoothly operate the lock body without rattling on the left and right sides of the lock body.

[0009]

In order to achieve the above object, the pneumatic pot of the present invention is provided with a recess for inserting a finger at the front of the upper wall of the upper cover, and a lower portion is provided at the front end of the recess. A through-hole is provided toward the front, a locking rib for a spring is provided on the front end wall of the recess, and a hanging claw having elasticity is provided on the left and right sides of the inner peripheral wall forming the through-hole, and the left and right hanging claws are provided. Each of the locking devices is provided with a lock body and a spring, and the lock body jumps over the right and left locking claws and the hanging claw which are locked in the locking grooves of the shoulder member. Left and right spindles fitted in the groove, locking ribs for springs, a front part that covers the through hole of the upper lid at the front upper surface, and an operation knob part that covers the upper front part of the recess of the upper lid at the rear upper part, Both ends of the spring are locked on both locking ribs Than it is.

[0010]

[Function] Since the lock device for the pneumatic pot is only a lock body and a spring, the number of assembly parts is very small.
In addition, with the operation knob of the lock body passed through the through hole from the back side of the upper lid and the front part also passed through the through hole, push up both support shafts of the lock body upward along both hanging claws of the upper lid. Just by fitting into both shaft grooves, the lowering of each shaft is supported by the hanging claw that forcibly jumped over, and only locking both ends of the spring to the spring locking ribs between the upper lid and the lock body Easy to assemble.
