Description

[Detailed description of the invention] The present invention relates to the structure of an oil-burning appliance, and in particular, an operating arm for moving up and down the wick is rotatably attached to one side of the body, and the combustion wick can be attached and detached from the operating arm. This provides a mounting structure for mounting on the

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings. Reference numeral 1 denotes a twisted sintered core. The twisted sintered core 1 is attached to a core protection tube 2 so as to be vertically slidable along a core guide tube 3 at the top of the vessel. A locking piece 5 provided with a hole 4 is provided in a protruding manner by spot welding or the like. On the other hand, a bearing 6 is formed on the front side of the vessel, and a shaft 8 of an operating arm 7 for vertically operating the twisted core 1 is rotatably mounted on the bearing 6. The other end protrudes outward and the operating arm 11 is pivotally attached. Further, on the outside of the shaft 8, a locking arm 15 having a hook 14 for engaging with the locking end 13 of the vibration detection arm 12 is rotatably attached.

On the other hand, the vibration detection arm 12 is rotatably attached to a holding frame 16 formed on the other side of the vessel, and a weight 17 for vibration detection is placed on the holding frame 16. An operating shaft 18 protruding from the lower part thereof is led out to the other end of the vibration detection arm 12. Further, the locking arm 15 is provided with a movable protrusion 20 protruding from it, and the operating arm 11 is provided with a long hole 19 for receiving the protrusion in a movable manner.

In this case, as an engagement mechanism for the elongated hole 19 of the protrusion 20, for example, a guide rail is formed on the locking arm 15, and a core adjustment plate provided with the protrusion 20 is mounted so as to be movable along the guide rail. . Further, a shaft 28 is provided protruding from the other end of the operating arm 7, and a holding roller 9 for engaging with the long hole 4 of the locking piece 5 is mounted thereon, as well as a spring 10 for pressing. do.

In the above configuration, the holding roller 9 can be formed of a molded product such as a hard synthetic resin, and the opening edge of the elongated hole 4 into which the holding roller 9 is inserted is provided with an abutting edge 27 by folding inward. to increase the contact area with the holding roller 9. Further, the operation arm 11, the locking arm 15, and the vibration detection arm 12 are provided with return springs 21, 25, and 2, respectively.
6 is installed.

With the above configuration, the springs 21, 25
When the operating handle 24 of the ignition arm 22 is pushed down against the ignition arm 22 and the locking arm 15 is rotated via the protrusion 23 opposite to this, the operating arm 1
1 also rotates, and the operating arm 7 is rotated through its shaft 8, and the core protection cylinder 2 is raised via the holding roller 9 and the locking piece 5. On the other hand, when the hook 14 of the locking arm 15 gets over the locking end 13 of the vibration detection arm 12 and the two engage, the twisted sintered core 1 can be held at the ignition position.

However, in the present invention, the core protection cylinder 2 is raised via the holding roller 9 and the locking piece 5 by the operating arm 7 which rotates around the shaft 8, but at this time, the holding roller 9 and the locking piece A large mechanical operating force is applied to the elongated hole 4 of 5. However, if the holding roller 9 is made of a hard synthetic resin that is resistant to mechanical action as described above, the friction caused by different materials can be reduced, and the abutment edge 27 can be formed on the opening edge of the elongated hole 4. By protruding, the contact area with respect to the holding roller 9 can be increased, concentration of mechanical operating force can be eliminated, and wear resistance and mechanical strength can be improved.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of the main structure of an oil-burning appliance showing an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the main part of the engagement portion between the core protection tube and the operating arm. In the figure, 1 is a twisted core, 2 is a core protection cylinder, 4 is a long hole, 5 is a locking piece, 7 is an operating arm, 9 is a holding roller, 10 is a spring, and 27 is a contact edge.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A bearing is formed on the side of the device body, an operating arm for raising and lowering the core is attached to the bearing, and a shaft is provided protruding from the end of the operating arm. A holding roller and a spring to press it are installed, and a locking piece with an elongated hole into which the holding roller is fitted is protruded from the protective cylinder of the combustion wick, and a locking piece is provided on the inner edge of the elongated hole. An oil-burning appliance characterized by forming an abutting edge by folding back the rim.
