Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for attaching a back plate of a hot-air heater, etc., which is used by housing a fuel tank containing liquid fuel inside.

[Conventional technology]

The configuration of a conventional hot air heater of this type will be explained with reference to FIGS. 4 and 5. 4 and 5, 1 is a main body case, 2 is a fuel tank that stores liquid fuel, 3 is an opening for storing this fuel tank in the main body case 1, and 4 is a cover that can open and close this opening. The attached lid 5 is a back plate that covers the open back part of the main body case 1.

Reference numeral 6 denotes a bent portion formed on the rear edge of the main body case 1, and the back plate 5 is attached to this bent portion with screws 7 at appropriate intervals.

8 and 9 are screw holes formed at appropriate intervals in the bent portion 6 and the peripheral edge of the back plate 5, respectively;
Reference numeral 10 denotes a reinforcing bent portion formed by bending the mouth edge of the storage opening 3 of the fuel tank 2.

[Problem that the invention attempts to solve]

Since the conventional warm air heater is configured as described above, when attaching the back plate 5, the screw holes 8 provided in the bent portion 6 of the main body case 1 and the screw holes 9 provided in the back plate 5 are connected. Screw 7 must be tightened while holding it in the matched position, and screw holes 8 and 9 must be tightened.
The position of the screws 7 is likely to shift, and a large number of screws 7 are required, which causes problems in that the work is time-consuming and the workability is poor.

In addition, if the tip of the screw 7 protrudes into the fuel tank storage space and the reinforcing bent portion 10 is small, it will get in the way when taking the fuel tank in and out, causing problems such as the risk of damaging the tank. It was hot.

This invention was made in order to solve the above-mentioned problems, and the purpose is to provide a rear mounting device for a hot-air heater, etc., which allows easy mounting of the back plate and reduces the number of screws.

[Means for solving problems]

The back plate mounting device according to this invention has a reinforcing bent part formed at the edge of the fuel tank storage opening provided on the top surface of the main body case, and a mounting bent part formed at the back end of the main body case. The bent part with a U-shaped cross section formed at the upper end of the back plate is held in place, and the other part is fixed with screws.

[Effect]

The back plate mounting device of this invention has a back plate between the reinforcing bent part formed on the edge of the fuel tank storage opening and the mounting bent part formed at the back end of the main body case. By pinching the bent portion having a U-shaped cross section formed at the upper end, the back plate is positioned, the screw holes are prevented from shifting, and the portion is fixed without screws.

[Example of idea]

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 to 3, numerals 1 to 10 are the same as the configuration of the conventional example, so the explanation thereof will be omitted. Reference numeral 11 denotes a bent portion formed on one side of the upper end of the back plate 5 and having a U-shaped cross section.

In the above embodiment, when attaching the back plate 5 to the back of the main body case 1, first
The bent portion 11 formed in the above is inserted between the pair of bent portions 6 and 10 formed on the main body case 1 side, and then the screw hole 8 of the bent portion 6 of the main body case 1 and the periphery of the back plate 5 are inserted. Align the screw holes 9 provided in the section. In this state, the bent portion 11 of the back plate 5 is held between the pair of bent portions 6 and 10 on the main body case 1 side, so it is only necessary to hold it with one hand, and the next tightening operation of the screws 7 is performed. It can be done very easily.

In addition, since the area near the bent portion 11 can be securely fixed without fixing with the screws 7, the number of screws 7 can be reduced, and the tips of the screws 7 will not protrude into the fuel tank storage space, so reinforcement There are no restrictions on the dimensions of the bending portion 10, and there is no fear of damaging the fuel tank 2 when taking it in or out. Further, since the pair of bent portions 6 and 10 formed on the main body case 1 side can be conventionally provided, the manufacturing cost can be reduced.

[Effect of idea]

As described above, according to this invention, there is a reinforcing bent part formed on the edge of the fuel tank storage opening provided on the top surface of the main body case, and a mounting part formed on the rear end of the main body case. The bent part, which has a U-shaped cross section formed at the upper end of the back plate, is held between the bent part and the other parts are fixed with screws, making it easy to align the back plate when installing it. Furthermore, the number of screws can be reduced, and there is no need to worry about damaging the tank with the tips of the screws when inserting or removing the fuel tank, which improves assembly efficiency and allows the device to be provided at low cost.
