Abstract

(57) [Abstract] [Purpose] To obtain a reliable nozzle holding device having a simple structure. A nozzle holding device comprising a nozzle 2, a nozzle holder 1 having a U-shaped support portion 1a for holding the nozzle 2, and a burner body 5 fixing the nozzle holder 1, the nozzle holder 1 comprising: Has a rising part 1b from the supporting part 1a, and has mounting holes 1c for mounting to the burner body 5 at both ends, and the rising part 1b is swaged to fix the nozzle 2. Fewer points, simpler structure and easier assembly. Further, since it can be screwed to the burner body 5, it does not come off easily.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a nozzle holding device.

[0002]

[Prior Art]

 A conventional nozzle holding device will be described with reference to FIG.

In the figure, the nozzle 2 is placed on a U-shaped support portion (not shown) of a nozzle holder 6 fixed to the burner body 5, and in this state, the nozzle is pushed from above the nozzle 2. It was fixed to the nozzle holder part 6 with a screw or the like.

[0004]

[Problems to be solved by the device]

 In the conventional nozzle holding device as described above, there are problems that the number of parts is large, the assembly is complicated, and the nozzle holding part 6 and the burner body 5 are not firmly fixed to each other.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and a nozzle including a nozzle, a nozzle holder having a U-shaped support portion for sandwiching the nozzle, and a burner main body for fixing the nozzle holder. In the holding device, the nozzle holder has a rising portion from the supporting portion and has mounting holes for attaching to the burner body at both ends, and the rising portion is swaged to fix the nozzle. I made it.

[0006]

[Action]

 In the above nozzle holding device, the nozzle holder has a rising portion that is raised from a U-shaped support portion that holds the nozzle, and has mounting holes at both ends for mounting to the burner body. The nozzle can be fixed by crimping the rising portion.

Further, the nozzle holder to which the nozzle is fixed can be fixed to the burner body by screwing.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a nozzle holder, and nozzle holder 1 is raised from two U-shaped support portions 1 a and 1 b that support a nozzle 2 and a pipe 3 described later on the upper surface. It has a portion 1b and mounting holes 1c at both ends. Reference numeral 2 denotes a nozzle for ejecting gas. The nozzle 2 has a groove 2a at the outer diameter of the central portion and a step portion 2b at the inner diameter of the root portion. Reference numeral 3 denotes a pipe, which has a convex flange portion 3a at its tip. Reference numeral 4 is an O-ring, 5 is a burner body, and the tip of the pipe 3 is screwed to the nozzle 2 through an O-ring 4. In this state, the groove 2a of the nozzle 2 and the flange portion 3a side of the pipe 3 are supported by the support portion 1a of the nozzle holder 1, and the rising portion 1b is swaged as shown by the arrow in FIG. The nozzle 2 is fixed to the nozzle holder 1. The nozzle holder 1 to which the nozzle 2 is fixed is fixed to the burner body 5 with screws through the mounting holes 1c.

Next, the operation of this embodiment will be described.

With the above configuration, the nozzle holding device can fix the nozzle 2 to the nozzle holder 1 by swaging the rising portion 1b.

Further, in the nozzle holding device, the nozzle holder 1 to which the nozzle is fixed can be fixed to the burner main body 5 with screws through the mounting holes 1c.

[0013]

[Effect of the device]

 According to the present invention as described above, in the above nozzle holding device, the nozzle holder has the rising portion and the mounting hole, and since the nozzle is fixed by swaging the rising portion, the number of parts is reduced, Since the structure is simple and the assembly is easy, there is an effect that an inexpensive nozzle holding device can be provided.

Further, since the nozzle holder can be screwed to the burner body through the mounting hole, the nozzle holder does not easily come off from the burner body, and there is an effect that a reliable nozzle holder can be provided.
