Description

Technical Field

[0001] The utility model relates to an electric welding protective hood, belonging to the technical field of welding protection. Background Art

[0002] Electric welding refers to a welding method that uses electric energy to achieve atomic bonding of the weldment through heating or pressurization, or both, with or without filler materials. The processing equipment used for electric welding is called an electric welder. The welded parts have the characteristics of good air tightness and light weight. Electric welding can also be used to achieve welding between ultra-thin and ultra-fine materials.

[0003] Most of the existing welding masks are handheld masks with simple structure and easy to use. For example, CN208017662U discloses a welding protective mask, which includes a mask body and a handle fixed at the lower part of the mask body for convenient holding by hand. A through hole is opened in the middle of the mask body, and a protective lens is sealed in the through hole in an openable and closable manner. The welding protective mask of this patent can only be used by holding the handle with one hand for welding and cutting operations, which reduces the work efficiency to a certain extent. Alternatively, CN218979443U discloses a head-mounted welding protective mask, which solves the problem of hand-held operation, but sparks fly during the welding and cutting process, and it cannot effectively protect exposed parts such as the neck.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figures 1 to 6 , the utility model provides a technical solution:

[0023] A welding protective head cover comprises a protective helmet 1 and a protective cover 2, wherein the protective cover 2 is arranged below the protective helmet 1, the protective cover 2 is a fiber cloth with fireproof and insulation properties, the fiber cloth is a silicon dioxide fire-resistant fiber cloth, the protective helmet 1 is made of carbon fiber, and the outer surface of the protective helmet 1 is provided with a fireproof and wear-resistant coating; the provision of the protective cover 2 can effectively protect exposed parts such as the neck, and two straps 21 are symmetrically arranged at the bottom of the protective cover 2. Since the protective cover 2 is made of fiber cloth, it may be lifted up under the action of strong winds and cannot protect exposed parts such as the neck, and it may also cause the protective cover 2 to be lifted up, resulting in accidents during the welding process, and so two straps 21 are provided. When in use, the user crosses the strap 21 over the arm and tightens it to the armpit. Due to the pulling force of the strap 21, the protective cover 2 will be pulled and fixed, thereby avoiding the above problems;

[0024] A visual window is arranged at the front of the protective helmet 1, and a welding protective lens 3 matched with the visual window is installed on the protective helmet 1 through a rotating device. A rotating shaft 11 and a turntable frame 4 are arranged on both sides of the protective helmet 1. The turntable frame 4 is fixedly sleeved on the outer wall of the rotating shaft 11. A gear slot 41 is arranged on the side of the turntable frame 4 away from the protective helmet 1. The gear slot 41 is arranged in a wavy line ring array. An elastic wall structure is rotatably arranged on the rotating shaft 11, and the elastic wall structure is fixedly connected to the welding protective lens 3. The elastic wall structure is used to cooperate with the gear slot 41 to realize the rotation / stop of the welding protective lens 3; the elastic wall structure can adopt any existing structure that can realize the sliding adjustment of the position of the welding protective lens 3; the welding protective lens 3 can be lifted up and kept relatively stable through the elastic wall structure;

[0025] The elastic wall structure includes a turntable 5 rotatably sleeved on the outer wall of the rotating shaft 11, and the side wall of the turntable 5 is provided with an elastic wall groove 51, a spring 52 is fixedly connected inside the elastic wall groove 51, and a marble 53 is fixedly connected to the end of the spring 52. The marble 53 cooperates with the gear slot 41 to realize the rotation / stop of the welding protective lens 3; when the marble 53 cooperates with the gear slot 41, the marble 53 shrinks inward due to the action of the internal spring 52, passes through the protrusion of the gear slot 41, and pops out again, thereby realizing adjustment.

[0026] At the same time, if Figure 6As shown, as a preferred solution, since some electricians have presbyopia and need to wear reading glasses to work, the position of the lenses will interfere with the welding device in actual operation. Telescopic frames 121 are installed on both sides of the cover body 12, and the ends of the telescopic frames 121 are connected to mounting bottom frames 122. The mounting bottom frames 122 are used to accommodate glasses frames 124 with corrective lenses 123 of appropriate degrees. The mounting bottom frames 122 can avoid horizontal position displacement, and ensure the stability of the position of the glasses frames 124, thereby ensuring the stability of the position of the corrective lenses 123 in the glasses frames 124, so that the operators can clearly observe the welding points. The glasses frames 124 can be moved to a suitable position by changing the telescopic frames 121. Specifically, the telescopic frame 121 has a certain friction force, which can ensure the stability of the relative position after adjustment. When the glasses frame 124 is not needed, the telescopic frame 121 is adjusted so that the glasses frame 124 will not block the line of sight; further, since the internal space of the protective helmet 1 is large and the cover body 12 is arranged at the rear of the protective helmet 1, that is, a large space is left between the front end of the protective helmet 1 and the cover body 12, on the one hand, it can avoid the protective helmet 1 from interfering with the human face and causing discomfort, and on the other hand, it can also provide sufficient installation space for the installation of the telescopic frame 121, which is convenient for the telescopic adjustment of the telescopic frame 121, so that the glasses frame 124 is in a suitable position, ensuring the clarity of the human eye when viewing objects.

[0027] The protective helmet 1 is provided with a plurality of evenly distributed breathing hoods 13 , and a filter is provided in the middle of the breathing hoods 13 .

[0028] The working principle of the above-mentioned welding protective hood is as follows:

[0029] After the staff puts the head into the protective helmet 1, they adjust the structure to match the head and firmly clamp it into the protective helmet 1, and then put their arms out of the straps 21, that is, the user puts the straps 21 over their arms and tightens them to their armpits. Due to the tension of the straps 21, the protective cover 2 will be pulled and fixed, which can avoid the protective cover 2 being lifted up under the action of strong wind and failing to protect exposed parts such as the neck.

[0030] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
