JPH09323747A - Device for opening/closing oil inlet cap - Google Patents

Abstract

PROBLEM TO BE SOLVED: To simplify a structure and easily allow injection molding by providing a lateral groove for locking a protrusion provided at an oil inlet cap to prevent the cap from removing when the cap is rotated in a direction for removing from a cap of a cartridge tank on a terminal of a longitudinal groove formed at an inner diameter part of an opening/closing part. SOLUTION: When an oil inlet cap 4 with protrusions is to be removed from a cap 3 of a cartridge tank 1 of a kerosene heater or the like, a device for opening/closing a cap 11 is rotated clockwise viewed from above. A plurality of protrusions 5 formed on an outer peripheral face of the cap 4 reach a position P1 of a lateral groove 13 connected to a terminal of a longitudinal groove 12 formed on an inner diameter part of the device 11. Therefore further rotation applies torque to the cap 4 with the terminal 14 of the lateral groove 13, so that the cap 4 rotates integrally with the device 11 and is removed from the cap 3. The position of the protrusions 5 of the cap 4 while it is removed from the cap 3 remains P1, wherein movement downward of the protrusions 5 is prevented by a groove wall 15, so that the cap 4 held in the device 11 without being removed from the device 11.

Description of the Related Art When removing the filler cap from a cartridge tank of an oil heater or inserting the filler cap into the cartridge tank, it is necessary to rotate the filler cap by hand. The fuel filler cap is in a state of being immersed in the fuel receiving port while the cartridge tank is supplying fuel to the combustion side of the oil heater, and therefore, when the cartridge tank is pulled up, it is wet with kerosene. In such a case, if the refueling port lid is covered with something and then screwed back, the hand can be opened without soiling the hand, and even if it is placed on the floor or the like in the covered state, the floor is not soiled.

る。The operation of the filler opening lid opening and closing device constructed as described above will be described. When refueling the cartridge tank 1, the filler cap lid opening and closing tool 6 is attached to the tank cap 3 of the container 2 of the cartridge tank 1 by fitting the protrusion 6 with the groove provided on the inner surface thereof. Cover 4 As a result, as shown in FIG. 5, the oil supply port lid with protrusion 4 is fitted into the recess of the oil supply port lid opening / closing device 6, and at the same time, the protrusion 5 of the oil supply port lid with protrusion 4 is provided on the inner peripheral surface of the oil supply port lid opening / closing device 6. It is inserted into the groove 7 to prevent rotation. Further, the magnetic force of the permanent magnet 8 causes the valve portion 10 to move.
The valve portion 10 is attracted to the permanent magnet 8. When the filler opening lid opening / closing device 6 is turned in this state, the protrusion 5 of the protrusion-containing oil supply port lid 4 is also locked in the groove 7, so that the protrusion-containing oil supply port lid 4 also rotates, and the protrusion-containing oil supply port lid 4 opens. And is removed from the tank base 3. At this time, since the valve portion 10 is attracted to the permanent magnet 8, the protrusion-added fuel filler cap 4 is held without being separated from the filler cap opening / closing tool 6.

きる。When mounting the oil supply port lid with protrusions 4 on the tank mouthpiece 3, the oil supply port lid opening / closing device 6 is attached to the tank mouthpiece 3 while the oil supply port lid opening / closing device 6 is held inside.
When it is covered with a cover and turned in the opposite direction to the front, the oil supply port lid with projection 4 is fastened to the base. In this case, the tank mouthpiece 3 is covered with the filler opening lid opening / closing device 6 facing downward, but since the magnet adsorbs the protrusion-added filler opening lid 4, the protrusion-containing filler opening lid 4 cannot fall from the filler opening lid opening / closing device 6. Without it, anyone can easily attach the protrusion-added oil filler cap 4 to the tank base 3.

作用を有する。In order to solve this problem, the present invention as set forth in the claims of the present invention is directed to an inner diameter portion of the cartridge tank which is provided with a diameter substantially equal to the outer diameter of the oil filler port lid. It has a vertical groove that allows the protrusion provided on the outer peripheral surface to be inserted from the opening side to the bottom side, and is fitted so as to cover the refueling port lid from above and then screwed back to remove the refueling port lid from the cartridge tank. A refueling port lid opening / closing tool, which locks a protrusion provided on the refueling port lid to prevent the refueling port lid from coming off when the fitted refueling port lid is rotated in a direction to be removed from the tank cap of the cartridge tank. The horizontal groove is provided at the end of the vertical groove. With this configuration, since the protrusion of the removed filler cap is moved into the lateral groove when the screw is unscrewed from the mouthpiece, it is retained inside so that the filler cap does not come off even when the filler cap is opened downwards. Further, when closing, the projection returns from the horizontal groove to the vertical groove, so that there is an effect that the fuel filler cap opening / closing tool can be easily removed from the fuel filler cap fitted in the tank cap.

れる。The operation of the filler opening lid opening / closing tool constructed as described above will be described. When detaching the fuel filler cap with protrusion 4 from the tank cap 3 (see FIG. 4) of the cartridge tank 1, the fuel filler cap opening / closing tool 11 is rotated counterclockwise when viewed from above (arrow AR1 direction). In this state,
The projection 5 reaches the position P1 in FIG. 3 and abuts against the end 14 of the lateral groove, and by further rotation, the oil supply port lid 4 with projection is given a rotational force by the end 14 of this lateral groove, and together with the oil supply port lid opening / closing device 11. It rotates counterclockwise and eventually comes off the tank base 3. The position of the protrusion 5 of the oil filler cap with protrusion 4 in the state of being disengaged from the tank mouthpiece 3 is still P1, and in this state, the downward movement of the protrusion 5 is blocked by the groove wall 15, so that the oil filler cap with protrusion 4 is Refueling port lid opening / closing tool 11
It does not come off and is retained in the filler opening lid opening / closing tool 11.
