Abstract

The utility model relates to a protective device for electric arc welding. The device is composed of parts, such as a protective cover, a fixing picture frame, a rotary picture frame, a pull wire, a trigger, a pair of electrode holders, etc. When the utility model is used for performing operations, only the trigger is wrenched and the rotary picture frame can be closed and opened by the traction of the pull wire. The device has the characteristics of compact structure, easy operation, labor saving and safety.

Description

The total journey of rotary switch formula electric welder's helmet

This utility model relates to a kind of welding preventer, specifically a kind of preventer that is become a hand operated by operator when welding by two hand operateds.

Traditional welding mask is covered with hand-held and wear-type, forms by protective cover, picture frame, screening glass, cover plate, and the right hand is held electrode holders during welding, and left hand is held face shield, even if the also handy left hand of wear-type lifts up puts down, and uses very inconvenient.

The purpose of this utility model just provides a kind of new design of welding preventer, to save the labour force, conveniently uses and operates.

This utility model is achieved in that and still comprises protective cover, picture frame, screening glass, cover plate in the device, on original picture frame, load onto the rotation picture frame, two ends by special backguy connect rotation picture frame and the trigger that is fixed on the electrode holders respectively, pull trigger and just can make the open and close of rotation picture frame.

Below in conjunction with accompanying drawing this utility model is further described.

As shown in the figure: protective cover (1), fixed picture frame (5) remains unchanged, left and right sides support (3) 9), left and right sides torque spring (4) (10) and rotation picture frame (8) are through on the same axle (2), and left and right sides support (3) (9) is installed in two upper lateral parts of fixed picture frame (5), trigger (11) is installed on the electrode holders (12) that handle has groove, one end of special backguy (7) and rotation Goggles frame (8) connect, the other end penetrates and trigger (11) connection from electrode holders (12) handle hole, and special backguy (7) is fixed on the protective cover (1) with wire clamp (6), after installing face shield is worn on the head, the right hand of holding electrode holders (12) is pulled trigger (11) just can make backguy (7) affect rotation Goggles frame (8) backspin, close form, just can weld, when stopping welding, trigger (11) is unclamped, utilize the elasticity of spring (4) (10), commentaries on classics Goggles frame (8) is opened automatically resetted.

This utility model is got final product by a hand operated; the left hand that uses traditional face shield to hold face shield has obtained liberation fully; idle left hand can replace the assistant to put workpiece; therefore saved the labour force; cleaning during welding slag because wear this new device; cover plate protection eyes are arranged again, prevented that welding slag from scalding eyes and skin and flesh, especially during work high above the ground; left hand can be climbed firm attachment; can avoid falling down the generation of traumatic injury accident, this apparatus structure is tightly beaten, and is easy and simple to handle; because of adopting the rotation form; rotate flexibly, wearing and tearing are few, guaranteed service life.

Claims

1, rotary switch formula electric welder's helmet assembly, relate to a kind of arc welding preventer, it is characterized in that it is by protective cover (1), fixed picture frame (5) and rotation Goggles frame (8), left and right sides support (3) (9), left and right sides torque spring (4) (10) on same axle (2), electrode holders compositions such as (12), support (3) (9), be installed in fixed picture frame (5) two upper lateral parts, connect rotation Goggles frame (8) respectively and be fixed on handle by the two ends of special backguy (7) and have trigger (11) on the electrode holders (12) of groove.

2, according to claim 1, it is characterized in that electrode holders (12) handle leaves a groove, special backguy (7) penetrates from electrode holders (12) handle hole.And and the trigger (11) that is installed in the groove place connect, pull trigger (11) and just can make backguy (7) affect the Goggles frame backspin to close form.
