DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] A confined space emergency ventilation device, such as Figure 1-Figure 3 As shown, including: The storage shell assembly 1 comprises a storage body 11 and an upper cover body 12 hinged to one side of the storage body 11, wherein the storage body 11 and the upper cover body 12 are respectively provided with corresponding storage chambers; A fan assembly 2 mounted on the inner wall of the storage chamber of the upper cover 12, wherein the fan assembly 2 can be stored in the storage chambers of the storage body 11 and the upper cover 12; and An opening and closing assembly 3 is arranged on the side of the storage body 11, and the opening and closing assembly 3 includes a first pushing component 31 rotatably installed on one side of the storage body 11, a rotating arm 32 rotatably connected to one end of the first pushing component 31, and an opening and closing hinge seat 33 hingedly matched with the rotating arm 32. The opening and closing hinge seat 33 is fixed on the storage body 11 and is located at the corner of the storage body 11. The rotating arm 32 is fixed on the upper cover body 12 so that the first pushing component 31 can drive the upper cover body 12 to be opened or closed from the storage body 11 when working.

[0021] According to a specific embodiment provided by the present invention, the storage body 11 is placed horizontally on the ground when in use, and the bottom of the storage body 11 has a counterweight structure, for example, the thickness of the storage body 11 is thickened, so as to prevent the upper cover body 12 and the fan assembly 2 from tipping over. The upper cover body 12 and the storage body 11 are structurally matched, and the upper cover body 12 can be covered on the upper part of the storage body 11, so that the fan assembly 2 can be stored in the storage chamber of the storage body 11 and the upper cover body 12. A pulling handle is provided on one side of the storage body 11, and the pulling handle is located on the opposite side of the hinged side. A rolling wheel 112 is installed on the hinged side of the storage body 11. After the storage body 11 is flipped over a certain angle, the rolling wheel 112 contacts the ground, so that it is convenient to bring the limited space emergency ventilation device to the infrastructure construction site for use, such as construction in a cable tunnel.

[0022] Specifically, the opening and closing hinge seat 33 on the storage body 11 and the rotating arm 32 on the upper cover body 12 are hinged, and the opening and closing hinge seat 33 and the rotating arm 32 are respectively provided with corresponding shaft holes, and the opening and closing hinge seat 33 and the rotating arm 32 are hingedly connected by a connecting shaft, so that the storage body 11 and the upper cover body 12 are hinged, so that the overall structural design of the storage shell assembly 1 can be made more compact, saving material costs and reducing design redundancy. The opening and closing hinge seat 33 is fixed at the corner of the storage body 11, and the rotating arm 32 also has an L-shaped fixing portion, which is fixed at the corner of the upper cover body 12 through the L-shaped fixing portion. Specifically, the switch cover hinge seat has an L-shaped fixing portion, so that it is matched with the corner of the storage body 11 and fixed. The purpose of installing it at the corner of the storage body 11 and the upper cover body 12 is to better realize the hinge connection between the storage body 11 and the upper cover body 12 and provide a connection point for the first pushing component 31 at the same time.

[0023] When the volume and weight of the storage shell assembly 1 are large, the weight of the upper cover body 12 itself is also large. At the same time, in order to prevent the upper cover body 12 from opening too quickly under the action of the first pushing member 31, or the upper cover body 12 from closing too quickly under its own gravity to damage the locking assembly 4, this embodiment has a damping structure coaxially arranged between the opening and closing hinge seat 33 and the rotating arm 32. The damping structure can be a disc damper 34, and the disc damper 34 can be installed with the center of the circle aligned with the axis of the rotation connection between the opening and closing hinge seat 33 and the rotating arm 32.

By setting the opening and closing component 3, the upper cover body 12 equipped with the fan assembly 2 can be easily opened and closed from the storage body 11 without relying on manpower. At the same time, by installing the opening and closing component 3, when the upper cover body 12 is in the open state, the position of the upper cover body 12 can be controlled by setting the stroke of the first pushing component 31, thereby adjusting the blowing direction of the fan assembly 2. At the same time, due to the supporting effect of the first pushing component 31, the upper cover body 12 is prevented from accidentally buckling on the storage body 11 when the fan assembly 2 is in the working state. In this embodiment, there is only one opening and closing component 3, which is only arranged on one side of the storage body 11, that is, it can be on the left or right side of the storage body 11, as long as it can open or close the upper cover body 12 and the storage body 11 as a standard.
