In order to solve the problem that the potential safety hazard exists when the person who wears the glasses among the prior art wears the air respirator face guard, the utility model provides an air respirator face guard and air respirator. Specifically, the air respirator includes an air respirator mask described below.

Example one

As shown in fig. 1, the air respirator mask includes a mask body 10, a frame 20, a frame insert bar 30, a socket frame 40, and a socket 50. The frame 20 is used for fixing lenses. The frame 20 is connected to the frame insertion rod 30. The socket frame 40 includes a first socket rod 41 and a second socket rod 42 which are arranged at an angle, the second socket rod 42 is located in the middle of the first socket rod 41, and the end of the first socket rod 41 is detachably connected with the frame socket rod 30. The socket 50 is provided on the mask body 10 and has a receiving portion to which the second socket bar 42 is fixed.

Through set up socket 50, socket 40, picture frame 20 and picture frame socket pole 30 on the air respirator face guard for the sealed not tight problem can not appear when wearing the air respirator face guard in the personnel that need wear glasses, has solved the potential safety hazard, and above-mentioned device can the high-speed joint, and convenient to use is swift.

In this embodiment, the frame 20 is removably connected to the frame stem 30. The first socket bar 41 and the second socket bar 42 are detachably connected. The lens frame 20 is detachably connected with the lens frame insertion rod 30, so that the lens frame 20 and the lens frame insertion rod 30 can be stored separately, the storage space is saved, the carrying is convenient, and the damage caused by the scratch of foreign objects is prevented. Similarly, the first socket rod 41 and the second socket rod 42 are detachably connected, so that the first socket rod 41 and the second socket rod 42 can be stored separately, the storage space is saved, the carrying is convenient, and the damage caused by the scratch of foreign objects is prevented.

Further, the frame insertion rod 30 and the frame 20 can be connected in advance for standby, and a plurality of frames 20 can be prepared according to the number of lenses in the frame 20, wherein the lenses in the frames 20 have different degrees, and are marked, so that the time for installing and replacing the lenses is reduced when an emergency situation occurs.

In this embodiment, socket 50 includes a mask connection piece 51 and a socket tube 52. The mask connecting member 51 is fixedly provided to the mask body 10. Socket tube 52 is provided on the mask connection piece 51 and projects in a direction away from the mask body 10, the socket tube 52 serving as a receiving portion.

Specifically, when the air respirator mask is installed, the second socket rod 42 of the socket frame 40 is inserted into the socket pipe 52, so that the frame 20, the frame socket rod 30 and the socket frame 40 can be fixed on the socket pipe 52, and then the whole device can be fixed on the mask body 10 through the mask connecting piece 51. The mask connecting piece 51 is connected with the mask body 10 in an integrated sealing manner, so that the sealing performance of the mask body 10 is ensured.

In this embodiment, the frame 20 is removably connected to the lenses. The lenses can be disassembled so that a person wearing the air respirator mask can select a suitable lens according to the degree of the person, thereby increasing the applicability of the air respirator mask.

In the present embodiment, there are two lens frames 20 and two lens frame insertion rods 30, and the two lens frames 20 are symmetrically disposed with respect to the insertion frame 40; two frame insertion rods 30 are symmetrically connected to both ends of the first insertion rod 41. The two frames 20 correspond to the eyes of the person, and the lengths of the frame insert rod 30 and the insert frame 40 are adapted to the distance between the eyes of the person.

In this embodiment, the end of the frame stem 30 away from the frame 20 has a press-fit, and the ends of the first stem 41 have slots into which the press-fit is inserted to fix the frame stem 30 and the frame 20.

Specifically, when the frame insertion rod 30 and the insertion frame 40 are connected, the press-fitting of the frame insertion rod 30 is pressed into the insertion groove of the corresponding size in the first insertion rod 41 of the insertion frame 40. When the lens frame is detached, the pressing buckle is pressed downwards, and the lens frame insertion rod 30 can smoothly withdraw from the slot. The beneficial effect of using the pressure to detain is that the pressure is detained and is pressed the picture frame and is convenient for to hold in the insert pole 30 gets into the first insert pole 41 of holding the insert frame 40 smoothly and correspond the slot of size, then, the pressure is detained automatically and is bounced, fixes in the slot to make the picture frame hold the connection between insert pole 30 and the socket frame 40 more firm, also be convenient for wear the personnel adjustment interpupillary distance of air respirator face guard.

In this embodiment, the frame 20 and at least one of the frame stem 30, the socket 40 and the socket 50 are titanium alloy materials. The service environment of air respirator face guard is mostly adverse circumstances such as high temperature, and air respirator face guard wears the face at people, and its quality can not be too big, still will guarantee sufficient intensity simultaneously. The titanium alloy material has the characteristics of high heat resistance, good corrosion resistance, high strength and light weight, so the mirror frame 20, the mirror frame insert rod 30, the socket 50 and the insert frame 40 in the embodiment are all made of the titanium alloy material.

In this embodiment, the frame 20 and at least one of the frame stem 30, the socket 40 and the socket 50 are polygonal in cross-section. Specifically, the cross sections of the frame 20 and the frame socket bar 30, and the socket 40 and the socket 50 in this embodiment are triangular, that is, the frame 20 and the frame socket bar 30, the socket 40 and the socket 50 are triangular prism structures. The structural style of the triangular prism can improve the overall stability of the socket, so that the lens frame 20, the lens frame socket rod 30, the socket frame 40 and the socket 50 can be stably arranged on the mask body 10.

Example two

The difference from the first embodiment is that the connection manner of the frame 20 and the frame insertion rod 30, and the connection manner of the first insertion rod 41 and the second insertion rod 42 are different from the first embodiment.

Specifically, in the present embodiment, the frame 20 is integrally formed with the frame insertion rod 30. The first socket bar 41 and the second socket bar 42 are integrally formed. The integrally formed connection mode can enhance the strength of the frame 20 and the frame insertion rod 30, and also enhance the strength of the first insertion rod 41 and the second insertion rod 42, thereby increasing the service life. Further, a plurality of integrally formed frames 20 and frame insertion rods 30 can be prepared according to the requirement, wherein the lenses in the frames 20 are lenses with different degrees and are marked, so that the time for mounting the lenses is reduced when an emergency situation occurs.
