Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a bearing portion into which a wick adjustment shaft of an oil-burning appliance with an upper and lower wick is inserted.

(Conventional structure and its problems) As shown in FIGS. 3 and 4, the structure of a conventional bearing tube is such that a bearing tube 11 equipped with a packing presser flange 12 is inserted through the side surface of a tank top plate 10. The tip was supported by a support piece 13 fixed to the inner surface of the tank top plate 10, and screwed to the side of the tank top plate 10 with screws 15 on both ends of the flange 12 through packing 16 in an oil-tight manner. It is something.

Therefore, in the conventional type, since the screws 15 are used for screwing, the pressure contact between the flange 12 and the side surface of the tank top plate 10 becomes uneven, which causes oil leakage from the packing 16. It was hot.

(Purpose of the invention) The present invention eliminates the above problems and secures the bearing pipe packing presser flange and the side surface of the tank top plate by uniform pressure contact through the packing to prevent oil leakage. This is what I am trying to do.

(Structure of the Device) In order to achieve the above object, the present invention is configured such that a threaded portion is carved at an appropriate location on the bearing tube, and a threaded hole to be screwed into the threaded portion is provided in the support piece or the insertion hole. ing.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described with reference to the drawings. In FIG. 1, 1 is a tank top plate, and 2 is a bearing tube integrally protruding from a packing presser flange 5 provided with a groove 4a into which a packing 4 is fitted at a proper position on the circumferential side. The tank is inserted into an insertion hole 1a drilled in the side wall of the tank, has a screw 2a carved in its tip, and is oil-tightly inserted through a packing 4 into a screw hole 3a drilled in a support piece 3 fixed to the inner surface of the tank top plate 1. It is screwed onto the

FIG. 2 shows another embodiment, in which a screw hole 1b is carved into the bearing tube insertion hole of the tank top plate 1, and a screw portion 2b that fits the screw hole 1b is formed at a suitable location on the outer circumference of the bearing tube 2. It is engraved and screwed on in an oil-tight manner.

(Effect of the invention) As described above, according to the present invention, the flange 5 and Since the packing 4 is uniformly pressed against the side wall of the tank upper plate 1, there is no fear of oil leakage from the joint between the bearing tube 2 and the insertion hole 1a. In addition, instead of the groove 4a of the packing presser flange 5, a concave groove is provided around the insertion hole 1a of the tank top plate 1, and the packing 4 is fitted into the groove 4a of the packing presser flange 5.
The same effect can be obtained even if it is attached so as to be pressed by a button (not shown).
