For the emergency personnel, the whole process is time-consuming and labor-consuming, and the emergency rescue work can not be carried out in time.

Based on the problem, the utility model provides a support body for fixed mounting positive pressure air respirator realizes dressing fast, has improved the efficiency of rescue work of speedily carrying out rescue work.

The following describes a detailed description of a frame body provided in the embodiments of the present invention with reference to the accompanying drawings, and these specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 2 is a schematic structural view of a frame body according to an embodiment of the present invention, as shown in fig. 2, the frame body 20 of this embodiment includes: a fixed plate 21 and an arc-shaped clamping plate 22;

the arc-shaped clamping plate 22 is arranged on the fixed plate 21, and the inner diameter of the arc-shaped clamping plate 22 is the same as the outer diameter of the gas cylinder 1;

the arc-shaped clamping plate 22 is arranged to be opened outwards, and the width of the opening of the arc-shaped clamping plate 22 is not larger than the outer diameter of the gas cylinder 1.

In this embodiment, the connection relationship between the fixing plate 21 and the arc-shaped clamping plate 22 can be selected in various forms as long as the connection between the fixing frame 21 and the arc-shaped clamping plate 22 is ensured to be reliable. For example, the fixing plate 21 and the arc-shaped clamping plate 22 of the frame body may be integrated, or the fixing plate 21 and the arc-shaped clamping plate 22 may be detachably connected.

Specifically, the arc-shaped holding plate 22 may be welded to the middle of the fixing plate 21, and this embodiment is not particularly limited.

Optionally, the fixing plate 21 is an elongated fixing plate, and the shape of the elongated fixing plate is rectangular, but not limited to rectangular.

If the elongated fixing plate is a rectangular plate, the long side direction of the rectangular plate should be perpendicular to the ground, and the opening direction of the arc-shaped holding plate 22 is perpendicular to the long side direction of the rectangular plate.

The frame body 20 is fixed to the wall by means of a fixing plate 21, and possible fixing means will be described below.

In one possible fixing manner, the fixing plate 21 is provided with a mounting hole 211, and the fixing plate is fixed on the wall through a pointed screw. The number of the mounting holes 211 is at least four, and the mounting holes are respectively provided at four corners of the fixed plate 21. Since the fixing plate 21 is usually a strip-shaped fixing plate, a row of mounting holes 211 may be additionally formed at the middle position of the strip-shaped fixing plate, so as to ensure that the fixing plate 21 can be stably fixed on the wall.

For the installation height of the frame body 20, the average height of the rescuers needs to be considered, and it should be ensured that when the rescuers stand in front of the frame body 20, the back frame of the positive pressure air respirator clamped on the frame body is just opposite to the back of the rescuers, so that the rescuers can wear the positive pressure air respirator.

Another possible fixing manner, fig. 3 is a schematic structural diagram of the slide provided in the first embodiment of the present invention, and fig. 4 is a schematic connection diagram of the fixing plate and the slide in the first embodiment of the present invention. The upper part of fig. 3 is a top view of the slide way, the lower part of fig. 3 is a front view of the slide way, as shown in fig. 3-4, in order to realize the adjustable installation height, a slide block 212 is vertically arranged at the center position of the back side of the fixing plate 2, and correspondingly, a slide way 9 matched with the slide block 212 is vertically arranged on the wall. According to the height of the rescue worker, through holes 91 with different heights and communicated left and right can be arranged in the horizontal direction of the side surface of the slide 9, baffles can be inserted into the through holes 91 and used for positioning the height of the fixing plate 21, and a structural schematic diagram of the slide comprising three through holes is shown in fig. 4. Through above-mentioned structural design, realize the regulation to support body 20 mounting height.

It should be noted that when the air cylinder 1 of the positive pressure air respirator 10 is clamped on the arc-shaped clamping plate 22, the back frame part bound on the air cylinder 1 should be located outside the frame body 20, so that the rescuers can wear the positive pressure air respirator.

The quantity of arc grip block 22 in this embodiment is at least one, because positive pressure air respirator's weight is indefinite, according to the practical application demand, to heavier positive pressure air respirator, can set up a plurality of arc grip blocks 22 at the interval on fixed plate 21, and a plurality of arc grip blocks 22's size of a dimension is the same, and is parallel to each other, and a plurality of arc grip blocks 22's top line is perpendicular with ground. Through the arrangement, the clamping force of the single arc-shaped clamping plate 22 is prevented from being insufficient, and the clamping effect of the gas cylinder cannot be well played.

Optionally, when the number of the arc-shaped clamping plates 22 is two, the interval between the two arc-shaped clamping plates 22 may be set as: greater than 1/2 of the length of the gas cylinder and less than 2/3 of the length of the gas cylinder, and through the arrangement, the weight of the gas cylinder is distributed on the two arc-shaped clamping plates 22, so that the clamping force on the gas cylinder is ensured.

It should be noted that the material of the arc-shaped holding plate 22 in this embodiment is a rigid elastic material. When guaranteeing the clamping force of arc grip block 22 to positive pressure air respirator 10, this arc grip block 22 should have certain elasticity, after the rescue personnel is dressing positive pressure air respirator 10, when moving to the direction of keeping away from support body 20, can make positive pressure air respirator 10 break away from arc grip block 22.

The method of using the positive pressure air respirator 10 fixed to the frame body 20 of the present embodiment will be described in detail below.

When taking place the poison gas leakage incident, the rescue personnel can run rapidly to the support body 20 position of installing positive pressure type air respirator 10 to back of the body positive pressure type air respirator 10 stands, then dress the braces of positive pressure type air respirator 10 on one's body fast, and take up the face guard, treat the back that finishes of dressing, the rescue personnel can remove to the direction of keeping away from the wall, because the arc grip block 22 of support body 20 has certain elasticity, thereby make the positive pressure type air respirator 10 of centre gripping on support body 20 break away from arc grip block 22 under the exogenic action. The whole process saves wearing time, is simple and convenient to operate, and is beneficial to rescue workers to carry out emergency rescue work quickly.

Because the rescuer moves in the direction far away from the wall after wearing the positive pressure type air respirator, the external force action can cause damage to the air bottle of the positive pressure type air respirator, therefore, on the basis of the embodiment, the two ends of the arc-shaped clamping plate are further improved to avoid the damage of the arc-shaped clamping plate to the air bottle.

The following detailed description will proceed with reference to the improved structure of the arc-shaped holding plate of the frame body according to the following specific embodiments.

Fig. 5 is a schematic structural view of a frame body provided by the second embodiment of the present invention, and fig. 6 is a schematic structural view of a frame body provided by the third embodiment of the present invention.
