the horizontal straight portion of door spigot 5 passes the removal hole that the outer wall of installation door 2 was seted up and extends to installation door 2 outside, and the surface of installation door 2 is seted up and is inserted 5 moving parts adapted shifting chute with the door, and the elastic component 3 of installation in the shifting chute, and the locating hole 51 of door spigot 5 looks adaptation is seted up to box 1 inner wall.

Specifically, two sets of horizontal inner walls of stiffening beam 13 and along the peripheral equidistance of slot seted up multiunit screw hole, wherein through two sets of locking bolt 15 fixedly connected with limiting plate 14 between two sets of screw holes. The reinforcement beam 13 can be tightly coupled to the back plate 102 and the frame 102 by laser welding.

Specifically, the edge position of the inner side wall of the installation door 2 is bonded with a damping pad 4, and the damping pad 4 is set to be of a double-layer structure.

Specifically, the box body 1 and the reinforcing beam 13 are both made of stainless steel or galvanized plates.

A novel box body manufacturing method is used for manufacturing the box body 1 and comprises the following steps:

s1, taking a square frame 101 and a square back plate 102, welding the back plate 102 to the frame 101 in a laser welding mode, and bending and welding an iron plate to form a combined body of the frame 101 and the back plate 102;

s2: welding a reinforcing beam 13 with a certain radian to the middle part of the frame, wherein the arc centripetal part of the reinforcing beam 13 faces the back plate 102;

s3: pressing down one side of the back plate 102 corresponding to the reinforcing beam 13 so that the back plate 102 is in contact with the reinforcing beam 13, welding the back plate 102 and the reinforcing beam 13 together by laser welding again so that the back plate 102 is concave inwards, and forming tension on the plate surface, wherein an included angle with an angle theta is formed between the back plate 102 and the plate surface before treatment;

s4: the other panels and the installation door 2 of the box body 1 are sequentially subjected to adaptive processing, and the box body 1 is assembled with other components into a complete box body 1, and the back plate 102 of the box body 1 presents a structure with a concave surface facing outwards.

Specifically, the included angle is-10 < theta <10 degrees, certain tension is formed on the metal back plate, surface looseness is avoided, the tension is smaller than the tensile strength of the plate, and the metal back plate is enabled to form a firm three-dimensional structure. As shown in fig. 6-7, after the reinforcement beam 13 is welded to the back plate 102, a downward tensile force F3 is generated in the recess of the back plate 102, and accordingly, a tensile force in the opposite direction is generated, i.e., a certain force F (tensile force) is generated between a and B. Taking the right end of the panel as an example, when the back plate 102 is not stretched, there is no tension, and since the back plate 102 is a multi-purpose iron piece in a conventional application, it is difficult to complete stretching when it is fixed to the frame 101, and the rattling of the rattling is easily caused by the wind. And the included angle of stretching of the reinforcing beam 13 is generally small. First, when the angle is viewed, the vertical tension of the downward tension at one end is F4, and the lateral tension is F1, then the relationship between the forces F along the arc surface of the backboard 102 is: sin θ is F4/F, then F4/sin θ. After stretching, if θ is 5 °, sin θ is calculated to be 0.087, and F is calculated to be 11.49 × F4, that is, the tension F on the back plate 102 is more than 11 times the vertical downward tension F4; the tension created by the other ends F1 and F4 is thus also difficult to push out. Therefore, under the design, each surface of the novel box body is in a tight state, and noise generated by vibration of the back plate 102 due to wind pressure of the external environment is avoided, so that the structure of the whole box body is firmer and more durable, and the requirement of the outdoor environment is met.

The theory of operation, this novel box, when using, when closing the chamber door, because the stroke that door inserted 5 is limited, its tail end can not reach the position of elastic component 3, but to the position of solid fixed ring 7, the limiting displacement of elastic component 3 prevents to insert 5 to push to the position of solid fixed ring 7 and open the door to the door. When opening, pushing down elastic component 3, moving door again inserts 5 for door is inserted 5 and is reached elastic component 3 position, makes elastic component 3 insert 5 to the door and carry out spacingly, and door is inserted 5 and is break away from the fixed of 1 with installation door 2 of box, at this moment will install door 2 and open. The normal gas meter is firstly fixed on a wall, then the meter box is buckled on the wall, namely the meter box is empty without a board surface by the wall surface, and the meter box is fixed on the wall by expansion screws. This time, the gas meter is installed on the two groups of stiffening beams 13, the locking bolts 15 are matched with threaded holes in the stiffening beams 13 to be connected with the limiting plates 14 to fix and limit the gas meter, then the installation door 2 is closed, the reverse moving door 5 is inserted, and the door 5 is fixed on the box body 1 and the installation door 2 through the telescopic effect of the compression springs.

The box body of the invention has a stable box body structure, combines an acute-angle windward side and a fastened support body, simultaneously reduces the formation of secondary sound waves, and is comfortable to surrounding and nearby people, especially for medium-sized and large-sized facilities.

The secondary sound wave is low-frequency irregular vibration, the vibration of a heavy object usually generates enough strength and obvious feeling, but the light-weight structure is provided with a thin wall and a box body, and a large area of material is easy to form, so that the secondary sound wave disturbs people only under the condition of being not easy to detect, and is very annoying.

In the experiment, people feel comfortable when the waves disappear, so that the infrasound treatment is a main index for the quality of a small environment), and the parts of the box body are made into a compact internal stretching structure with a plane function, so that the possibility of generating the infrasound by the vibration of the box body can be effectively reduced.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
