Description

[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is a lock handle for an incinerator that is attached to the input door of a household incinerator used in general households or a commercial incinerator used in business establishments, factories, hotels, schools, public facilities, etc. Regarding lock structure.

[0002]

2. Description of the Related Art As a conventional lock structure for a lock handle for an incinerator, a lock structure having a structure in which a lock piece on the lock handle side is simply locked with a hook on the main body of the incinerator, or a lock piece on the lock handle side is used. After locking on the hook, the lock handle is moved further as an operation to ensure the locking, or the lock door is rotated to rotate the lock handle and the closing door has a strong tightening force. There was something that was used for high pressure, which was locked in and sealed so that the gas inside the main unit would not come out to the outside.

[0003]

However, the structure in which the hooking piece is simply hooked with the hook is not limited to the case where the hooking state is always reliable, and the hooking piece is slightly hooked on the hook. There are times when it is not possible to reliably hang it. In particular, if the incineration material bursts inside the incinerator, there was a risk that the loading door would open and an accident could be injured to a person nearby. Also, in the case of the structure in which the lock handle is moved so that the hook piece can be surely attached to the hook, when the lock is released, even if the lock handle is returned to the original position, the hook piece does not come off and the hook remains as it is. Since it remained in a state where it did not separate, the operation had to be troublesome because the hanging pieces had to be manually removed from the hooks one by one. Moreover, since the heat of the incinerated material is conducted to the hanging piece and it is heated, it cannot be grasped with bare hands, and it is necessary to wear gloves and the like without fail. Further, the high-voltage type has a problem in that the lock handle has to be rotated many times, and the lock operation is troublesome and is a heavy work.

An object of the present invention is to provide a lock structure for a lock handle for an incinerator, which can be locked easily and reliably without using excessive force.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, that is, a spring is inserted inside a lock handle from which a lock pin is projected,
When the lock pin is floated from the closing door by a spring and the lock pin is hooked with the hook, the elastic force of the spring strengthens the hooked state.

[0006]

Next, the operation of the present invention will be described. Attach the lock handle (1) to the closing door (7) in advance. At this time, a spring (4) is attached to the lock handle (1).
By the action of, it becomes a state of being levitated from the closing door (7) [Fig.
(See (a)]. First, hold the lock handle (1) and press it toward the closing door (7). Then lock handle (1)
Is no longer floating, and the end surface of the boss (3) comes into contact with the flange of the boss (3) fixed to the closing door (7) [Fig.
(B)]. After the contact, the lock handle (1) is rotated until the lock pin (13) is inserted into the hooking portion of the hook (6) [see FIG. 3 (c)]. Then release the lock handle (1) to release the lock pin (1
3) contacts with the hooking portion of the hook (6) by the action of the spring (4) [see FIG. 3 (d)]. At this time, the elastic force of the spring (4) is applied to the lock handle (1) to lock the lock handle (1), so that the lock handle (1) continues to be reliably held in the locked state.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. (1) is a boss (11) having a stepped through hole (11a)
And a long lever (12) with two protruding pieces on one end side.
And a lock pin (13) projecting from the outer periphery of the boss (11). Reference numeral (2) is a round bar protruding from the closing door (7), a threaded portion (2a) is provided at the tip of the round bar (2), and the round bar (2) is provided with a boss (11). Penetrates into. (3) is a boss that penetrates the round bar (2) and is fixed to the closing door (7), and a hole (3a) into which the spring (4) is inserted and installed is bored inside the boss (3). The outer diameter of the boss (3) is set so that it can be inserted into the stepped through hole (11a), and its length is shorter than the depth of the stepped through hole (11a).
Reference numeral (5) is a nut screwed with the screw portion (2a). (6)
Is a hook fixed to the incinerator body (8), and the hook (6) hooks the lock pin (13).

[0008]

[Effects of the Invention] The present invention having the above-described structure has the following effects.

In the present invention, it is not necessary to rotate many times as in the case of rotating the conventional lock handle (1), and as in the case of moving the lock handle (1), gloves are put on and the hooking piece is manually attached. It is not necessary to remove it one by one, and it is possible to perform a very simple one-touch locking operation, and even a woman can easily open and close the loading door (7) of the incinerator body (8).

With the product of the present invention, the incinerator body (8)
Even if the incineration material bursts inside, the closing door (7) does not open, and a strong and reliable locked state is achieved, so it is safe to work near the incinerator body (8).

In the locked state, the closing door (7) is pressed by the spring (4) to prevent smoke and generated gas from leaking inside the incinerator body (8). It can be installed and used in.
