Description

  The present invention relates to a gas pipe fixing bracket for mutually fixing a gas pipe and a thermal power control apparatus in a gas stove device.

  In the gas stove device, gas pipes for sending gas introduced from the outside to various places in the gas stove device are laid. For example, when three thermal power control devices are arranged on the back side of the front panel of the gas stove device, gas pipes are laid in the left and right longitudinal directions at the bottom of the gas stove device. These three thermal power adjusting devices are juxtaposed at predetermined positions.

  An opening is formed on the upper surface of the gas pipe at a position where each thermal power control device is attached, and a cylindrical gas inlet that protrudes downward from the lower surface of the thermal power control device is inserted into the opening of the gas pipe. In this way, the thermal power control device is connected to the gas pipe. However, an O-ring is attached to the outer periphery of the inlet so that gas does not leak from the connecting portion, and the gas piping is connected between the thermal power control device so that the gas piping and the thermal power control device are in close contact with each other. The fixing bracket is screwed to the thermal power control device so as to sandwich the gap (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2002-5427 (FIG. 1)

  The conventional fixing metal fitting is provided with a curved portion for holding a gas pipe at the central portion of a rectangular sheet metal, but the portions located on both sides of the curved portion are flat plate-shaped, and the flat plate-shaped portion Since only a round hole for screwing is formed in the fixing bracket, when fixing the fixing bracket with two screws to the thermal power control device, the fixing bracket will not fall off when the first screw is screwed together The fixing bracket swings when the first screw is completely tightened, and the other round hole matches the screw hole on the thermal power control device side when tightening the remaining screws. Without such a problem, the work of attaching the fixing bracket becomes very troublesome.

  Then, this invention makes it a subject to provide the fixing fitting for gas piping which can perform a screwing operation | work easily in view of said problem.

In order to solve the above problems, a gas pipe fixing bracket according to the present invention is provided with a gas pipe sandwiched between connecting portions of a thermal power control apparatus in a state where the thermal power control apparatus is connected to a gas pipe laid in a gas appliance. In the gas pipe fixing bracket for fixing the gas pipe and the thermal power control device to each other by being screwed into the two screw holes, the screw is fixed when screwed to the thermal power control device. It has a movement prevention part that sandwiches the stopper part formed in the vicinity of the hole from both sides along the longitudinal direction of the gas pipe, and when the screw is screwed into one screw hole, the end on the other screw hole side parts is not more that so as not to swing, the movement-preventing unit is characterized in that it is formed at the distal end of the longitudinal folded portion in a direction orthogonal to the gas pipe.

  By forming a stopper part on the thermal power adjustment device side and sandwiching the stopper part with a movement prevention part formed on the fixing bracket, it is not necessary to hold the fixing tool by hand when first tightening the screw, and Since the fixing bracket does not swing when the first screw is tightened, the remaining screws can be tightened continuously.

  In addition, when the movement preventing part is formed by bending a part of the fixing metal, even if the bending angle varies, the movement preventing part is formed by bending it in a direction perpendicular to the longitudinal direction of the gas pipe. The range does not vary.

  As is clear from the above description, the present invention does not need to hold the fixing bracket by hand when initially tightening the screw, and the fixing bracket does not swing when the first screw is tightened. The remaining screws can be tightened continuously, and the fixing work can be facilitated.

  Referring to FIG. 1, reference numeral 1 denotes a heating power adjusting device incorporated in a gas stove device. By swinging a heating power adjusting lever 12 left and right, an adjusted amount of gas is transferred from a nozzle 11 to a gas burner (not shown). It is a eruption. The gas is supplied from a gas pipe 2 installed in the gas stove device. Therefore, the thermal power control apparatus 1 and the gas pipe 2 are connected to each other, and the fixture 3 is used so that the connection is not removed.

  With reference to FIG. 2, an opening 21 is formed in the gas pipe 2 at a location where the thermal power control apparatus 1 is connected, and gas is introduced into the thermal power control apparatus 1 through the opening 21. The connecting operation of the gas pipe 2 and the thermal power control apparatus 1 is performed in a state where the thermal power control apparatus 1 is turned upside down.

  Referring to FIG. 3, a cylindrical introduction port 14 for introducing gas into the thermal power control apparatus 1 is provided in the lower part of the thermal power control apparatus 1 (the upper part in FIG. 3 because the thermal power control apparatus 1 is inverted). Thus, the introduction of the inlet 14 into the opening 21 of the gas pipeline 2 connects the thermal power control device 1 and the gas pipe 2.

  Two screw holes 13 are provided across the introduction port 14, and the fixing bracket 3 is set in a state where the introduction port 14 is inserted into the opening 21, and the two screws 4 are respectively inserted into the screw holes 13. By screwing, the thermal power adjusting device 1 and the gas pipe 2 are fixed so as not to be separated.

  Referring to FIGS. 4 and 5, the thermal power adjusting device 1 has stopper portions 15 formed on the outer sides of the screw holes 13. Reference numeral 5 denotes an O-ring for preventing gas leakage. Further, the fixing metal 3 is formed by processing a rectangular metal plate by sheet metal processing, and an arch-shaped curved portion 32 for holding the gas pipe 2 is formed at the center portion. A round hole 31 through which the screw 4 is inserted is formed at a position corresponding to the screw hole 13 with the curved portion 32 interposed therebetween.

  Further, a movement preventing portion made up of a pair of claw portions 33 is bent outside each round hole 31. The interval between the two claw portions 33 that form a pair is set such that the stopper portion 15 can be sandwiched from both sides along the longitudinal direction of the gas pipe 2. Therefore, as shown in FIG. 3 above, when the fixing bracket 3 is attached in a state where the thermal power control apparatus 1 and the gas pipe 2 are connected, the two pairs of claws 33 sandwich the stopper portion 15 respectively. Even if it is released, the fixture 3 is stable and does not fall. In this state, both the round holes 31 coincide with the screw holes 13, respectively.

  When the screw 4 is screwed into one screw hole 13 and completely tightened, the fixing bracket 3 is tightened in the tightening direction, that is, clockwise by friction between the seat surface of the head of the screw 4 and the upper surface of the fixing bracket 3. Even if it is going to swing, the claw portion 33 comes into contact with the stopper portion 15 and the fixing bracket 3 does not swing. Therefore, when the remaining screw 4 is screwed into the other screw hole 13, the state in which the round hole 31 matches the screw hole 13 is maintained. The screw 4 can be tightened. As shown in FIG. 5, when the claw portion 33 is bent, it is bent in a direction perpendicular to the longitudinal direction of the gas pipe 2. By bending in this direction, even if the bending angle varies, the distance between the pair of claws 33 does not change.

Next, a fixing bracket as a reference example is shown in FIG. In this case, as shown in FIG. 6, the fixing bracket 6 in which the claw portion 63 is bent in the direction along the longitudinal direction of the gas pipe is shown in FIG. was Rukoto used similarly to the fixing bracket 3 is also possible according to the present invention. The round hole 61 and the curved portion 62 are the same as the round hole 31 and the curved portion 32.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
