Abstract
The utility model relates to a novel electric welding helmet of lens open-close type, it has solved the technical problem that the lens opened and shut. The technical characteristics are that the upper horizontal edge of the square mirror bracket is a mirror bracket shaft, a button spring and a rotating wheel are installed on the shaft, a control box for realizing the opening and closing of the mirror bracket is a cylinder, a pressing plate controlled by a spring, a hook and a hook groove plate is installed on the lower portion of an inner cavity of the control box, a contact with the spring and a bullet-shaped fork rod is installed on the upper portion of the control box, two ends of a control line are respectively connected with the rotating wheel and the hook groove plate, and when the pressing plate moves up and down, the hook hooks the hook groove plate or breaks away from the hook groove plate, so that the opening. The utility model discloses be convenient for observe the welding condition, need not hand, convenient to use, safety, raise the efficiency.
Description
This utility model relates to the novel welding helmet of a kind of eyeglass open-close type.
Existing welding helmet is two kinds of hand-held and wear-types, two kinds all is not the eyeglass open-close type, be not easy to observe the welding situation in the welding, and hold face shield or often pull face shield with hands always, notification number is that the electric welding head protector of CN21438992 and CN2146873 all needs in welding manually, this class weld cap aloft weld or weld in the overhead position in particularly inconvenience, exist and be unfavorable for safe factor.
The purpose of this utility model is, folding at any time is provided, and is convenient to observe welding quality, need not hand, and is easy to use, increases work efficiency, and welds, helps in overhead welding and the butt welding the novel welding helmet of a kind of eyeglass open-close type of safety operation aloft.
The technical solution of the utility model is achieved in that establishes fixing collar at the ellipse garden shape helmet in lower edge garden week, around helmet transverse center position, corresponding two ears two fixing bands that hang down, article two, the control box of dress control eyeglass closing device in being provided with in the middle of the lower end of fixing band, be provided with the face shield that the top intermediate lateral is shaped on arcuate groove in helmet front portion, but on the face shield be folding has been fixed at the center with axle and pedestal mirror holder with the arcuate groove, it cooperates, separates with the picture frame that is located at the face shield middle part, is provided with control line between runner and the control box.
Excellent beneficial effect of the present utility model is: but because eyeglass folding at any time, so help observing welding quality, accelerate speed of welding, raise the efficiency, need not hand weld cap, can vacate hands in the operation and do the security protection work of self, help aloft welding, butt welding, the narrow and small place welding of overhead welding and space.

Tell about embodiment below in conjunction with accompanying drawing:
The novel welding helmet of eyeglass open-close type, comprise the helmet (10), face shield (3), mirror holder (6), pedestal (7), knob spring (8), runner (9), control box (2), in the lower edge garden week of the ellipse garden shape helmet (10) fixing collar (11) is arranged, around helmet transverse center position, corresponding two ears two fixing bands (12) that hang down, fixing band flexibly connects with the hook of its end and the control box that is arranged between two bands, it is arc being provided with end surface shape in the front portion of the helmet (10), the top intermediate lateral is shaped on the face shield (3) of arcuate groove, the face shield and the helmet are all with asbestos or engineering plastics injection mo(u)lding, and face shield (3) is fixedlyed connected with the helmet (10), face shield (3) is gone up with the arcuate groove be the center with spool (13) and pedestal (7) but fixed the mirror holder (6) of folding, it cooperates with picture frame built in face shield (3) middle part, separate, sealing ring 4 is housed in the picture frame, mirror holder (6) is a square steel wire frame, its top is mirror holder axle (13), runner (9) is equipped with in the centre of axle, knob spring (8) is equipped with on both sides respectively, runner (9) is connected with the two ends of control line (1) respectively with the interior hook frid of control box (2), control line (1) has the steel wire brake cable of overcoat for the band wire core, control box (2) is a cylindrical shell, one place of its inwall is axially arranged with a retainingf key (21), spiral cover (22) is equipped with in the bottom of control box (2), the interior center fixation of spiral cover (22) has steel elastic hook (19), be provided with pressing plate (18) on the top of control box inner hanging hook (19), compression spring (20) has been fixed in the bottom of pressing plate (18), there are keyway and key (21) to be slidingly matched on the Wai Yuan limit of pressing plate (18), there is aperture at the center of pressing plate (18), the bottom of aperture and the corresponding fixed-site of hook (19) the hook frid, there is the anchor line (string) hole lower end of hook frid, the bottom has been installed for dull and stereotyped in the top of control box (2), top is the contact (14) of thin barrel, dull and stereotyped Wai Yuan has keyway and key (21) to be slidingly matched on the limit, the central upper portion of contact (14) inwall has been fixed spring (15) and steel elasticity fork arm (16), fork arm (16) places the center of spring (15), and the following fork of fork arm (16) is respectively aduncate inclined-plane.
At ordinary times on top that the effect lower platen (18) of spring (20) places control box (2) promptly under the pulling of control line (1) eyeglass (5) be in closed dress attitude, when the operator need open eyeglass, open slightly and chew contact under the promotion of lower jaw (14) and just move down, the flat board of contact (14) presses down pressing plate (18), hook the groove of hook frid at elastic force effect lower draw-bar (19), control line (1) is released, mirror holder under the effect of knob spring (8) (6) is opened eyeglass (5), closes to chew contact (14) and be reset.Because hook (19) is between the fork seam of fork arm (16), so during the baseplane of the interior inclined-plane of fork arm lower end by hook (19), fork arm (16) is separated, and breaks away from hook, and jaw closes up, fork arm resets in reseting procedure.Open fork arm when chewing (16) presses down the hook gib head with its bottom through small holes ramp once more, hook breaks away from the hook frid, effect lower platen (18) at spring (20) resets, the tension control line, overcome the knob power of knob spring (8), rotating wheel drives the mirror holder eyeglass that closes fast, repeats to realize the random folding of eyeglass with this.
