Description

Welding protective mask

Technical Field

The utility model relates to a welding protective face mask belongs to welding apparatus technical field.

Background

the welding process can generate smoke and strong light, and the possible injuries to human bodies include burns, electric shock, visual damage, toxic gas inhalation, excessive ultraviolet irradiation and the like. Therefore, the welder needs to use a protective mask during work. The existing protective mask has single function, or can be held only by hands, or is fixed only by an elastic band, and has no universality. In addition, the welding process needs to be stopped continuously to observe the welding seam, and the observation is not clear due to the optical filter.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a welding protective face mask solves above-mentioned technical problem.

In order to realize the purpose, the utility model discloses a technical scheme is:

A welding protective mask comprises a mask which can cover the face and extend backwards to protect; the mask is provided with an elastic fixing belt; an observation window embedded with transparent glass is arranged on the face mask, an eye shield capable of covering the observation window is hinged above the outer side of the observation window, and an optical filter is embedded in the eye shield; the sponge strip is arranged at the edge of the inner side of the face mask in a surrounding way, and the inner side of the face mask is provided with an auxiliary observation cover with the end part jointed with the outline of the eyes corresponding to the observation window; the lower end of the face mask is detachably provided with a handle through threaded connection.

The utility model discloses technical scheme's further improvement lies in: the two elastic fixing belts are respectively positioned at the upper part and the lower part of the mask.

The utility model discloses technical scheme's further improvement lies in: the eye shield is provided with a handle for holding and rotating.

The utility model discloses technical scheme's further improvement lies in: the handles are arranged on two side surfaces of the eye shield.

Since the technical scheme is used, the utility model discloses the technological effect who gains has:

the utility model discloses an articulated cover glass that sets up, sets up the observation window that has clear glass simultaneously, can the person of facilitating the use under the good condition of assurance environment, the observation welding seam of knowing at any time can provide good protection for the user at operating condition's any homoenergetic constantly.

The utility model discloses an observation window is inlayed and is set up clear glass, can be when opening the cover glass with the flue dust and the high-temperature gas isolation after the welding outside the face guard, cover glass and clear glass can form dual protection.

The utility model discloses set up the sponge strip at the inboard edge of face guard position, the user has comfortable sensation when using facial pressing close to the sponge strip, and the sponge strip can also play the filtering action, filters the gas that gets into in the face guard, prevents that the smoke and dust from getting into.

The utility model discloses simple structure, convenient to use can accomplish good comprehensive protection to the user, and comprehensive performance is good.

Drawings

Fig. 1 is a perspective view of the present invention;

Fig. 2 is a perspective view of another perspective of the present invention;

The device comprises a face mask 1, a face mask 2, an elastic fixing band 3, an observation window 4, an eye shield 5, a light filter 6, a sponge strip 7, an auxiliary observation cover 8, a handle 9 and a handle.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments:

The utility model discloses a welding protective face mask is the instrument of a welding usefulness, has improved current protective face mask, makes its performance better. The following are specific examples:

The welding protective mask of the utility model, as shown in fig. 1 and fig. 2, comprises a mask 1 which can cover the face and extend the protection to the back. The mask 1 provides the most basic protection for the user against the effects of high temperatures on the human body. The face mask 1 is provided with the elastic fixing belt 2, so that a user can sleeve the face mask on the head without holding the face mask by hands, and other work can be conveniently done by two hands. Preferably, two elastic fixing bands 2 are arranged and are respectively arranged at the upper part and the lower part of the mask 1, so that the wearing stability of a user is ensured.

The utility model discloses set up the observation window 3 of inlaying transparent glass on face guard 1, still articulate the cover glass 4 that can cover observation window 3 in 3 outside tops of observation window simultaneously. The eyeshade 4 is inlaid with the optical filter 5, the optical filter 5 can filter harmful visible light generated during welding, accordingly eyes are protected, objects are observed through the optical filter 5, and the sight is dark. The eye shield 4 is hinged and can be rotated upwards to be opened. For example, when the welding gap needs to be observed, the eye shield 4 can be rotated upwards to be opened, and at the moment, the user can normally observe the welding seam through the observation window 3 under the condition of brighter light. The observation window 3 is embedded with transparent glass, and can isolate the smoke dust and high-temperature gas after welding outside the face mask 1.

the utility model discloses 1 inboard edge position of face guard is encircleed and is set up sponge strip 6, and through setting up sponge strip 6, the user has more comfortable sensation when using facial sponge strip 6 of pressing close to sponge strip 6 can also play certain filtering action, filters the gas that gets into in the face guard 1, prevents that the smoke and dust from getting into.

The utility model discloses 1 inboard observation window 3 that corresponds of face guard sets up tip and the supplementary observation cover 7 of eye contour laminating, and when the welding, the user both eyes lean on supplementary observation cover 7. This arrangement enables the viewing window 3 to be separated from the interior of the mask 1, preventing the effect of the gases exhaled by the user on the transparent glass on the viewing window 3 from fogging. As shown in particular in figure 1.

the utility model discloses can dismantle through threaded connection and set up handle 8 at 1 lower extreme of face guard, the user can install handle 8 according to the demand. For example, when welding for a long time, the protective mask is worn by using the elastic fixing band 2; when welding is performed for a short time, the welding tool can be held by hand by using the handle 8.

In the specific implementation of the utility model, the eye shield 4 is also provided with a handle 9 for holding the rotation. In particular, the handles 9 may be provided on both sides of the eye protector. The user can hold the handle 9 and rotate the eye protector 4 open. As shown in particular in fig. 2.

the utility model discloses an articulated cover glass that sets up, sets up the observation window that has clear glass simultaneously, can the person of facilitating the use under the good condition of assurance environment, the observation welding seam of knowing at any time, the security is good.
