DETAILED DESCRIPTION

[0020] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0021] Example:

[0022] Reference Figure 1-Figure 5A gas pressure regulating box that is easy to maintain, including a pressure regulating box body, which is formed by a bottom plate 1, a back plate 3 integrally formed with one end of the bottom plate 1, side plates 4 hinged at both ends of the back plate 3, and a box cover 5 hinged at the top of the back plate 3, a pressure regulating device 2 is installed on the top of the bottom plate 1, and a pop-up component for opening the box cover 5 is provided between the back plate 3 and the box cover 5;

[0023] The pop-up assembly includes two groups of gas springs 9 and a torsion spring 8. A sleeve 6 is provided at one end of the box cover 5. A fixing rod 7 penetrating the inner side of the sleeve 6 is provided at the top of the back plate 3. The fixing rod 7 is connected to the sleeve 6 through the torsion spring 8. Two groups of gas springs 9 are hinged on one side of the back plate 3. The other ends of the two groups of gas springs 9 are hinged to the bottom of the box cover 5.

[0024] Specifically, through the two sets of hinged side panels 4 and the box cover 5, the enclosure and unfolding of the pressure regulating box body can be facilitated. Under the joint action of the two sets of gas springs 9 and the torsion spring 8, the box cover 5 can be easily popped up. Furthermore, through the above structure, the pressure regulating device 2 can be easily exposed, which is convenient for the staff to observe from all directions and greatly improves the operational convenience of the staff.
