Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a light-shielding helmet for attaching a holder that replaces a light-shielding helmet or a hand shield used for work such as arc welding and semi-automatic welding.

[0002]

[Prior art]

 As shown in Fig. 3, light-shielding helmets, hand shields, apron, arm covers, foot covers, leather gloves, etc. have been used as protective equipment for arc welding or semi-automatic welding work. A light-shielding helmet and a hand shield are used to protect the face. Among them, light-shielding helmets are often used for welding with long beads such as welding at shipyards and upward welding, but in other welding, the actual hand shield is used regardless of arc welding or semi-automatic welding. is there. However, regardless of whether it is a light-shielding helmet or a hand shield, welding is usually started, that is, arc strike is performed outside the groove, but the base metal is tapped lightly or the base metal is lightened at the tip of the welding rod. The arc is generated in this way. If you wear a light-shielding helmet or put a hand shield on your face during the first arc strike, you cannot see the arc strike part. Therefore, in the case of an arc strike, a light-shielding helmet or a hand shield is not used, but the fact is that the face is shook, and in the case of welding small items, hold one of the base materials with the left hand. The base part with a welding rod and tap the base metal with the tip of the welding rod or lighten the base metal to generate an arc, which adversely affects the eyes and burns the face. There was a problem.

[0003]

[Problems to be solved by the device]

 For this reason, it is an issue to be solved by the present invention to develop a protector capable of reliably protecting the eyes and face at the time of arc strike in arc welding or semi-automatic welding.

[0004]

[Means for Solving the Problems]

 The present invention was developed as a solution to the above problem, and is an attachment that can be freely rotated and tilted in all directions at one end of a light-shielding shield and can be detachably attached to the body of a holder. It does not present a light-shielding shield for mounting the holder in arc welding etc. that is equipped with metal fittings.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described below. In FIG. 1, 1 is a shield, 2 is a mounting bracket, 3 is a holder, 4 is a welding rod, and 5 is a base material. The shield 1 is provided with a light-shielding window 6 at the bottom so that the arc strike area can be confirmed. The shape of the shield 1 is slightly narrower than that of an ordinary hand shield. This is because the shield 1 is used with it attached to the holder 3 so that the weight can be reduced. Therefore, the material and the like can be the same as those of a normal hand shield, but it is desirable that the thickness be a little thin, but the width etc. It is not limited to this embodiment. In addition, it is possible to use a heat-resistant and light-shielding plastic plate as the shield material. In the case of this plastic shield, the processing is easy and the weight is light, so that it is effective for the purpose of the present invention. is there.

As shown in FIG. 2, a mounting metal fitting 2 to be provided at the lower end of the shield 1 has a cylindrical main body 8 having a bottom plate 7, and a spherical body 10 having a mounting rod 9 welded to the upper part thereof. A rubber body 12 is inserted between the bottom plate 7 and the bottom plate 7 via a contact plate 11. Mounting plates 13 are welded to both sides of the main body 8, and upper ends of the mounting plates 13 are each bent inward to form a holding portion 14 for holding the sphere 10. Since the rubber body 12 is appropriately pressed through the abutment plate 11 by the screw 15 which is formed by screwing a screw hole into the bottom plate 7, the spherical body 10 is held between the rubber body 12 and the holding portion 14. Therefore, it is configured so that it can rotate and fall over freely in all directions. A screw hole is also threaded on one side of the mounting plate 13 so that a set screw 16 is screwed in so that when the mounting bracket 2 of the shield 1 is mounted on the holder 3, the set screw 16 is fixed. I am configuring. The rubber body 12 may be a compression spring, and the mounting plate 13 may be made of a thin spring steel material. When the spring steel material is used, the set screw 16 is unnecessary. The mounting bracket 2 itself is not limited to the structure shown in this embodiment.

[0007]

[Effect of the invention]

 As described above, according to the present invention, an arc is provided at one end of the light-shielding shield 1, which can be freely rotated and fallen in all directions and which can be detachably mounted on the body of the holder 3. Since it is a light-shielding shield for attaching the holder in welding, etc., the shield 1 is attached to the holder 3 even in the case of welding small objects, so check the points even if you do not use a hand shield or the like during arc strike. While generating an arc, the face is protected. Also, continuous welding can be performed as it is even after shifting to normal continuous welding, or the shield 1 that has been covered can be lowered and the shield 1 can be tilted toward the arm. However, if normal welding is performed after arcing, the face can be completely protected with the hand shield and the shield 1 can be tilted toward the arm. Since the mounting bracket 2 only presses the sphere 10 against the holding part 14 with the rubber body 12, it can freely rotate and fall over in all directions, so the mounting angle of the shield 1 can be adjusted according to the location of the arc strike. Can be changed. In addition, when the mounting plate 13 of the mounting bracket 2 is made of spring steel, the shield 1 is attached to the holder 3 by the elasticity of the spring, so that the shield 1 is easy to remove and the shield 1 is removed after lowering the light-shielding helmet. It has a very remarkable practical effect such as easy removal.
