Abstract
The utility model discloses a welding helmet. The front part of a helmet body is provided with a pair of retractable goggles the upper parts of which are fixedly connected with a moving rod, and the moving rod is provided with moving teeth. The helmet body is provided with a motor, the motor drives gear wheels, and the gear wheels are matched with the moving teeth to realize the opening-closing of the goggles. The lower part of the helmet body is provided with a switch for controlling the motor, and the switch is controlled by the touching or extrusion of the lower jaw of a welding person. By the motor, the gear wheel or a gear set and the switch arranged on the helmet body, the welding person can control the motor by the lower jaw, so that the lifting of the goggles can be realized, and the opening-closing is more convenient. When the welding person uses the welding helmet in welding, the welding person does not put down a welding torch, can control the lifting of the welding helmet by the lower jaw and can always watch the welding conditions. Therefore, the convenience and the welding speed of welding are increased.
Description
Technical field
Eye protection device when this utility model relates to a kind of welding, especially a kind of welding helmet.
Background technology
Welding is to send the high light of dazzling the eyes, and this high light has very big infringement to human eye, and for the eyes of protecting welding personnel escape injury, welding personnel is equipped with eye protection device more when welding, as welding helmet.But existing welding helmet is the protective eye lens that folding is housed in the front of medicated cap body, utilizes the protection of the protective capacities realization of protective eye lens to eyes.Existing welding helmet need strike out protective eye lens with the hand in the gap of welding in use, observes the welding situation, will cause like this welding job pause, prolong weld interval.It is manipulation to put down welding gun during each folding protective eye lens, and the folding of protective eye lens is more loaded down with trivial details.
The utility model content
The technical problems to be solved in the utility model provides a kind of welding helmet of controlling the protective eye lens folding with convenience.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: but its front portion at the medicated cap body is provided with the protective eye lens of folding, is connected with carriage release lever on the top of protective eye lens, and carriage release lever is provided with mobile tooth; Be provided with motor on the medicated cap body, driven by motor has gear, and gear matches with mobile tooth and realizes the folding of protective eye lens; Be provided with the switch of control motor in the bottom of medicated cap body, switch is realized control by the touching or crowded the rolling of the chin of welding personnel.
As preferred version of the present utility model, described gear train is to be consolidated with driving gear by motor, and driving gear is realized and being in transmission connection of mobile tooth by the change-speed gearing of switching on the medicated cap body.
Further preferred version is to be provided with to limit the locating part that carriage release lever swings on the medicated cap body of carriage release lever middle and upper part.
Adopt the beneficial effect that technique scheme produced to be: motor, gear or gear train, the switch of this utility model by on the medicated cap body, being provided with, make welding personnel can realize the lifting of protective eye lens to the control of motor by chin, folding is convenient.Welding personnel need not put down welding gun when using this utility model welding, be the lifting of may command weld cap by chin, can watch the situation of welding at any time, thereby has improved the convenience and the speed of welding of welding.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, but the structure of this welding helmet is the protective eye lens 9 that is provided with folding in the front portion of medicated cap body 11, and protective eye lens 9 is arranged on the medicated cap body by being plugged on, the draw-in groove 7 of protective eye lens both sides moves up and down, and realizes folding.Be connected with the carriage release lever 10 of bar shaped on the top of protective eye lens 9, a side of carriage release lever 10 is provided with mobile tooth 6.On medicated cap body 11, be fixed with motor 3; The gear train that is rotationally connected on medicated cap body 11, gear train is driven by motor 3.Described gear train constitutes by the driving gear 1 on the arbor 2 that is fixed in motor with the change-speed gearing 5 of driving gear 1 engagement, and on medicated cap body 11, the mobile tooth 6 of the gear teeth of change-speed gearing 5 and carriage release lever meshes change-speed gearing 5 by connecting axle 4 switchings.The gear teeth quantity of change-speed gearing 5 is far longer than the gear teeth quantity of driving gear 1, thereby effectively rotating speed of motor is carried out speed change, realizes deceleration transmission, makes carriage release lever 10 carry out lifting with rational speed.Certainly an also available independent gear replaces gear train.
Shown in Figure 1, this welding helmet is provided with the switch of control motor 3 in the bottom of medicated cap body 11, the touching of the chin that this switch can be by welding personnel or squeeze to roll and realize control; Described switch is preferably travel switch 8, and it is more convenient to make it control.Shown in Figure 1, this welding helmet is provided with on the medicated cap body of carriage release lever 10 middle and upper parts can limit the locating part 12 that carriage release lever swings.
This welding helmet welding helmet in use, welding personnel is worn over the medicated cap body on the head, with chin touching or squeeze and roll travel switch, protective eye lens moves down under the drive of motor and gear train, thereby the eyes of welding personnel are protected, and can weld; When needing to open protective eye lens in welding process, welding personnel is touched once more with chin or is squeezed and rolls, motor with last time switched in opposite direction rotate, move up by gear set drive carriage release lever and protective eye lens, realize the unlatching of protective eye lens.
Claims (4)
1. welding helmet, but its front portion at the medicated cap body is provided with the protective eye lens of folding, it is characterized in that: and the top at protective eye lens is connected with carriage release lever, and carriage release lever is provided with mobile tooth; Be provided with motor on the medicated cap body, driven by motor has gear or gear train, and gear or gear train match with mobile tooth and realize the folding of protective eye lens; Be provided with the switch of control motor in the bottom of medicated cap body, switch is realized control by the touching or crowded the rolling of the chin of welding personnel.
2. welding helmet according to claim 1 is characterized in that described gear train is to be consolidated with driving gear by motor, and driving gear is realized and being in transmission connection of mobile tooth by the change-speed gearing of switching on the medicated cap body.
